外文資料:
China is a mining power and mining equipment manufacture and use of mechanical and electrical power.From the 20th century,modeled after the 50's the first since the mine hoist has been designed and manufactured,used more than 6,000. With the needs of the community and the rapid development of technology,mining industry production equipment and facilities need to mechanization,electrification,The mining industry is the throat of the elevator equipment,replacement products,old products long time run,the structural problems behind the original exposed prominent fault more serious impact on the safety of mining operations,curb the rapid development of mining industries to the national economy with to the adverse effects.With the ever-changing mine to increase production ,upgrade the machine to improve safety,of machine to run automated,reducing operation and maintenance of the labor intensity,the speed of of the accident and so on,into the urgent requirement.Mine hoist for renovation,is extremely important. For example,wood lining hoist drum serious wear and tear,when the trees lining up to a certain degree of wear and tear on the lining must be replaced wooden reel,or a security incident is likely to affect the safety in production.And replacement of wooden drum liner is a very cumbersome process,while the high cost of wood lining reel,high maintenance costs, maintenance time.Consume a large amount of manpower,material and time at the same time,and affects the security of the entire mine production and demand for production,to that end, the design of a reel turning wood lining device is a very necessary technology.As a result of taking into account the existing trees lining reel slot car there are many devices deficiencies,the paper lining from the existing wooden reel slot cars of the principle of analyzing devices,wear and tear on wire rope of research,the role of drum parts and the forces analysis of the existing car tank equipment to improve processing methods and applications,based on the user-friendly, effective and practical under the premise of turning wood on the drum liner device was designed to maximize the improvement of steel wire rope and reel service life of wood lining and reduce production costs and shorten the processing and maintenance cycle,reducing the labor intensity.Through constantly improving and perfecting the design of the drum lining wood turning can be a convenient device for turning wood drum liner,the installation of wire rope to reduce wear and tear,but also extended the service life of wooden drum and the lining can produce a substantial savings cost.
HKM2×4×1.8-based transformation of hoist
Jiaomei jiulishan mine hoist HKM2×4 ×1.8 Department of the former Soviet Union and type of products manufactured in the 50's,the reel structure of a typical shell thick branch. Put into use since 1963 until now,has been running for 47 years,for a total of about 64 million out of coal t.With the increasing production to meet the needs of the mine production in 1982 had a greater technological innovation,the annual output from 1,200,000 t to 1,800,000 t. Enhance the increase in weight as a result of running some time after percutaneous invagination and open reel welding,crack phenomenon. Also in 1985 inside the drum in two directions along the circumference,respectively,an increase of the I-11 # 2,to increase the support drum,to try to resolve open reel reel welding and the phenomenon of skin retraction.However, after running for some time, the support drum parts and drum skin open welding,the cracks gradually serious phenomenon,there are four supported I-beam 3 has a horizontal fracture,open reel welding vice 21,all four I-beam horizontal fracture.In order to ensure safety in production,we have adopted a variety of methods,such as an increase to strengthen the board,direct welding, hit 45 ° groove welding, welding,after annealing,and so will not solve the problem of DC welding,but welding arising as a result of repeated stress concentration,so that Open welding phenomenon more serious run-time hoister abnormal dislocation metal sound, has seriously affected the security of the entire mine production.In order to ensure safety in production, production management group and the jiulishan mining joint research,the status quo through the survey and found that the existence of the following issues:
1.Invagination serious skin drum,about 10~12mm,resulting in severe deformation of wood lining,the sound of running.
2.Lord, Vice-reel wood lining wear inconsistent,resulting in the main,the Deputy reel run that is inconsistent paragraph rope wrapped around the lame often said,resulting in loading,unloading difficulties.
3.Reel support I-beam and drum parts are cracking skin serious run soon after welding cracks,and cracks have been increased and extended. Is the main,the Deputy reel 8 to support the horizontal I-beam are broken,cracks in skin reel has been extended to drum brake wheel, hoist the wrong run-time anomalies metal sound.
4.The high maintenance costs.Reel hoist wood lining must be replaced once a year,each to be 24h,the material consumption for 35,000 yuan.
5.Repair time.Reel monthly reinforcement welding carried out in more than 16h,consume a large amount of manpower,material and time.
Due to these aspects of the fault,resulting in the normal operation of hoist can not be seriously affected the security of the entire mine production and demand for production,for which a technological transformation of the reel.
Rehabilitation programs
As the replacement cost of the elevator and the time too long,not in conformity with the actual scene,after full investigation, research and feasibility analysis,we have decided to upgrade the existing machines on the basis of the transformation, that is,to keep the original motor, speed machine,the braking system,the spindle and spindle support device round, the replacement of the main,the Deputy reel and reel spokes.The use of the new reel CITIC Heavy Machinery Company with a fixed rope groove, the structure of the reel one,two and a half of each reel by the reel of the drum skin is 40mm thick rolled steel plate 16Mn,tungsten above have fixed rope groove,which is a weak branch structure Cryptocarya high-strength roll.
Drum replacement program and a key link:
(1)The new reel will be processed to the scene,
(2)Installed in the garage outside the drilling of two in order to field drilling,
(3)Crane transform garages, walk in part by the manually read electric,
(4)The laying of railway, from the bus garages Shop Housing, in order to save time for the delivery drum,
(5)Preparation of a cable car, the garage is responsible for the lifting of work outside the drum,
(6)Principal, vice skip on the wellhead,
(7)Hoist to remove the gate and gate post,
(8)Spoke to the old Office disconnected from the reel, cut in half, were transported onto the Housing
(9)New drum hanging in place, the scene is looking for its eyes. And then transported onto the room, eyes drilling with drilling,
(10)through eyes will be hanging a new reel in place, Reaming and bolts,
(11)Field testing of the hoist at all stages of technical parameters and characteristics,
(12)Pile gate and gate installation and test on the ropes。
Program to determine how to ensure that the installation of the new reel spindle centerline and the centerline of coincidence is the key to this project. After studying the use of the original decision to hoist the main branch of the only round I,as a benchmark to look for now. When the old reel suspended from the Spindle, the technical staff from the new reel to detect only the spindle diameter and round the mouth of the branch diameter, and calculated only the mouth space, the new reel position determined by the gap is quite good, and then use Support round the old hole in the new roll number of the spokes on the eyes, drilling, Reaming, the last link to the original reel wheel support.
Works in several technical issues
（1）CITIC Heavy Machinery Company to use the vernier caliper to provide a new reel on the mouth and the only round of the spindle support Uehara I only measured the diameter of 1.5mm drum replacement.
（2）Diameter of the brake drum wheel drum brake wheel than the original diameter increased by 40mm the original wooden gates to re-processing.
（3）To increase the connection of the fastening screws, we adopted the first measurement of hole diameter, screw-processing method is to ensure co-ordination of the screw size, and the use of anaerobic technology to enhance the connection of the fastening.
Through the joint efforts of all the construction workers, which lasted 60h, the successful completion of the task. After field testing, the new reel to run a smooth, radial drum beat, the oval-round gate, the two-drum winding rope to meet the requirements of the accumulated error.
Effective
The total cost of million renovation project to completely upgrade the operation to solve the problems of insecurity, and ensure the safety of all mine production. Considerable economic benefits, compared with the transformation of the former:
(1)Savings once a year to replace wood lining reel maintenance time, saving each time 24h,
(2)Once a year to replace wooden drum lining material consumption, a total of 35,000 yuan.
(3)Twice a month savings Consolidation reel maintenance time per month of 16h,a year can save maintenance time 192h, can record 1.642 million yuan in profits.
Transformed in less than a year to recover the full investment. At the same time enhance our province to fill a gap machine.
Modified operation
After the transformation,from January 1995 until now,has been running for more than 15 years,4.2 million to upgrade coalt, running in good condition,compared with the transformation of the former has the following advantages:
(1) Completely eliminate the original invagination drum skin, cracks,the phenomenon of lift to run a smooth, no noise, and ensure the safety in production.
(2) As a result of the strong integration of thick shell support structure,the total elimination of the support of the original drum parts (I-) fracture phenomenon and improve the overall strength.
(3) Trough as a result of the use of fixed ropes,there is no inconsistency rope groove wear, thereby overcoming the countries of origin,the Deputy reel winding rope running above inconsistencies and enhance the work efficiency,
(4）Greatly reduce the workload of maintenance and repair saves time,saves maintenance costs
（5） Extended the life of wire rope.Trough as a result of the use of fixed rope to remove the original wire rope hoist run-time switch to the phenomenon of bite rope to rope to run a smooth,extended its service life and improve the whole system to enhance security.
Some Experience
Old-fashioned elevator renovation,is now facing the problem of the old mines in general,as the long run and changed mine,the expansion of most of the original hoist production can no longer meet the security needs of the operation，There are hidden dangers of insecurity,the need for reform.But how the transformation is a widespread problem.Although the replacement of hoist solve the problem,but the high cost of long hours do not meet the needs of actual production of coal,and the transformation of the mine,I opened up a shortcut to solve the problems not only save a lot of cost and time, with a certain degree of practicality and the value of a wide range of promotion.

我國(guó)是一個(gè)采礦大國(guó),也是礦山機(jī)電設(shè)備制造和使用大國(guó)。從20世紀(jì)50年代仿造第一臺(tái)礦山提升機(jī)以來(lái),至今已設(shè)計(jì)制造,使用了近6000多臺(tái)。隨著社會(huì)需求和現(xiàn)代技術(shù)的高速發(fā)展,礦山工業(yè)企業(yè)亟待生產(chǎn)設(shè)備及設(shè)施的機(jī)械化,電氣化,現(xiàn)代化。而礦山工業(yè)的提升機(jī)是咽喉設(shè)備,產(chǎn)品不斷更新?lián)Q代,老產(chǎn)品運(yùn)行年深日久,原本落后的結(jié)構(gòu)問(wèn)題暴露突出,故障增多,嚴(yán)重影響礦山的安全運(yùn)轉(zhuǎn),抑制了礦山工業(yè)的高速發(fā)展,給國(guó)民經(jīng)濟(jì)帶來(lái)了不良的影響。隨著國(guó)內(nèi)礦井產(chǎn)量的日新月異的提高,對(duì)提高提升機(jī)的安全性,可靠性,生產(chǎn)效率以及整機(jī)自動(dòng)化運(yùn)行水平,降低操作者及維護(hù)人員的勞動(dòng)強(qiáng)度,處理設(shè)備事故的速度與對(duì)策等,成了迫切要求。對(duì)于礦井提升機(jī)的更新改造,具有極其重要的意義。例如提升機(jī)卷筒襯木的磨損嚴(yán)重，當(dāng)襯木磨損達(dá)到一定程度時(shí)就必須更換卷筒襯木，否則就很有可能出現(xiàn)安全事故，影響安全生產(chǎn)。而更換卷筒襯木又是一個(gè)十分繁瑣的過(guò)程，同時(shí)卷筒襯木價(jià)格昂貴，維修費(fèi)用高，維修時(shí)間長(zhǎng)。消耗大量人力、物力和時(shí)間的同時(shí)，又影響了全礦的安全生產(chǎn)和產(chǎn)量的需求，為此，設(shè)計(jì)一個(gè)卷筒襯木車削裝置是一項(xiàng)十分必要的技術(shù)改造。由于考慮到現(xiàn)有卷筒襯木車槽裝置存在許多不足之處，本文從現(xiàn)有卷筒襯木車槽裝置的原理分析入手，通過(guò)對(duì)鋼絲繩磨損的調(diào)研，卷筒部件的作用和受力情況的分析，現(xiàn)有車槽設(shè)備加工方法的改進(jìn)和應(yīng)用，立足于方便，高效、實(shí)用的前提下對(duì)卷筒襯木車削裝置進(jìn)行設(shè)計(jì)，目的在于最大程度的提高鋼絲繩和卷筒襯木的使用壽命，降低生產(chǎn)成本，縮短加工和檢修周期，減緩了勞動(dòng)強(qiáng)度。通過(guò)不斷地改進(jìn)和完善，設(shè)計(jì)的卷筒襯木車削裝置可以很方便的進(jìn)行卷筒襯木車削，該裝置減少了鋼絲繩的磨損，又延長(zhǎng)了卷筒襯木的使用壽命且可大幅度節(jié)約生產(chǎn)成本。
HKM2×4×1.8型提升機(jī)的改造
焦煤九里山礦主井提升機(jī)HKM2×4×1.8系原蘇聯(lián)又型50年代制造的產(chǎn)品,其卷筒結(jié)構(gòu)為典型的厚支薄殼。自1963年投入使用至今,已經(jīng)運(yùn)行了47年,共計(jì)出煤約6400萬(wàn)t。隨著產(chǎn)量的逐年增加,為滿足該礦生產(chǎn)的需要,1982年進(jìn)行了一次較大的技術(shù)改造,年產(chǎn)量由120萬(wàn)t增加到180萬(wàn)t。由于提升重量的增加,運(yùn)行一段時(shí)間后,出現(xiàn)卷筒皮內(nèi)陷及開(kāi)焊、裂縫現(xiàn)象。1985年又在兩卷筒里面沿著周長(zhǎng)方向分別增加了兩根11# 的工字鋼,來(lái)增加卷筒的支撐,試圖解決卷筒開(kāi)焊及卷筒皮內(nèi)陷現(xiàn)象。但運(yùn)行一段時(shí)間后,卷筒的支撐件和卷筒皮開(kāi)焊、裂縫現(xiàn)象逐漸嚴(yán)重,4根支撐工字鋼有三根已經(jīng)橫向斷裂,副卷筒開(kāi)焊21處,4根工字鋼全部橫向斷裂。為保證安全生產(chǎn),我們采取了各種方法,如增加加強(qiáng)板,直接焊接,打45°坡口焊接,焊接后退火,直流焊接等都不能解決問(wèn)題,反而由于多次焊接而產(chǎn)生應(yīng)力集中,使開(kāi)焊現(xiàn)象更加嚴(yán)重,提升機(jī)運(yùn)行時(shí)有金屬錯(cuò)位的異常響聲,已經(jīng)嚴(yán)重影響到全礦的安全生產(chǎn)。為保證安全生產(chǎn),集團(tuán)公司生產(chǎn)管理處和九里山礦聯(lián)合進(jìn)行調(diào)研, 通過(guò)對(duì)現(xiàn)狀的調(diào)查,發(fā)現(xiàn)存在有以下幾方面的問(wèn)題:
1.卷筒皮內(nèi)陷嚴(yán)重, 約為10~12mm，致使襯木變形嚴(yán)重,運(yùn)行有響聲。
2.主、副卷筒襯木磨損不一致,致使主、副卷筒運(yùn)行段纏繩不一致即常說(shuō)的瘸腿,造成裝、卸煤困難。
3.卷筒的支撐件工字鋼和卷筒皮均開(kāi)裂嚴(yán)重,焊接后運(yùn)行不久又開(kāi)裂,且裂縫一直在增加和延伸。現(xiàn)主、副卷筒的8根支撐工字鋼均橫向斷裂,卷筒皮的裂縫已經(jīng)延伸到卷筒閘輪上,提升機(jī)運(yùn)行時(shí)有金屬錯(cuò)位的異常響聲。
4.維修費(fèi)用高。提升機(jī)的卷筒襯木每年必須更換一次,每次需24h,材料消耗為3.5萬(wàn)元。
5.維修時(shí)間長(zhǎng)。每月對(duì)卷筒進(jìn)行的燒焊加固均在16h以上,消耗大量的人力、物力和時(shí)間。
由于以上幾方面的故障,造成提升機(jī)不能正常運(yùn)行,嚴(yán)重影響了全礦的安全生產(chǎn)和產(chǎn)量的需求,為此對(duì)該卷筒進(jìn)行了技術(shù)改造。
改造方案
由于更換整個(gè)提升機(jī)費(fèi)用太高且時(shí)間又長(zhǎng),不符合現(xiàn)場(chǎng)的實(shí)際，經(jīng)過(guò)充分的調(diào)查、研究和可行性分析,我們決定在現(xiàn)有的提升機(jī)基礎(chǔ)上進(jìn)行改造,即保留原有電機(jī)、減速機(jī)、制動(dòng)系統(tǒng)、主軸裝置和主軸支輪,更換主、副卷筒及卷筒輪輻。新卷筒采用中信重型機(jī)械公司制造的帶有固定繩槽、一體結(jié)構(gòu)的卷筒,每個(gè)卷筒由兩個(gè)半卷筒組成,卷筒皮為40mm厚的16Mn鋼板卷成,上面鎢有固定的繩槽,屬厚殼弱支結(jié)構(gòu)的高強(qiáng)度卷筒。
卷筒更換的方案及關(guān)鍵環(huán)節(jié):
(1) 將加工好的新卷筒運(yùn)到現(xiàn)場(chǎng),
(2) 在車房外安裝兩臺(tái)鉆床,以便現(xiàn)場(chǎng)鉆孔,
(3) 改造車房的天車,行走部分由手動(dòng)改為電動(dòng),
(4) 鋪設(shè)鐵道,從車房?jī)?nèi)鋪出車房,以節(jié)省運(yùn)送卷筒的時(shí)間,
(5) 準(zhǔn)備一臺(tái)的吊車,負(fù)責(zé)車房外卷筒的起吊工作,
(6) 將主、副箕斗放在井口,
(7) 拆除提升機(jī)的閘及閘樁,
(8) 將老卷筒從輪輻處斷開(kāi),切割成兩半,分別運(yùn)出車房
(9) 將新卷筒吊到位,現(xiàn)場(chǎng)找正號(hào)眼。然后運(yùn)出車房,用鉆床鉆眼,
(10) 將鉆過(guò)眼的新卷筒吊到位,鉸孔并聯(lián)接螺栓,
(11) 現(xiàn)場(chǎng)測(cè)試提升機(jī)各技術(shù)參數(shù)和各個(gè)階段的特征,
(12) 安裝閘樁和閘,并上繩試車。
方案確定后,如何保證新卷筒的安裝中心線與主軸中心線重合是此項(xiàng)工程的關(guān)鍵環(huán)節(jié)。經(jīng)研究決定利用原提升機(jī)主軸支輪上的止口,做為基準(zhǔn)來(lái)進(jìn)行找正。當(dāng)老卷筒吊離主軸后,由技術(shù)人員測(cè)出新卷筒的止口直徑和主軸上支輪口的直徑, 并算出止口間隙,新卷筒的位置按算好的間隙確定,然后利用支輪上的老孔在新卷筒的輪輻上進(jìn)行號(hào)眼、鉆孔、鉸孔,最后將卷筒聯(lián)接在原支輪上。
工程中的幾個(gè)技術(shù)問(wèn)題
(1) 利用中信重型機(jī)械公司提供的游標(biāo)卡尺對(duì)新卷筒的止口和主軸上原支輪止口的直徑1.5mm進(jìn)行測(cè)量卷筒更換。
(2) 卷筒的閘輪直徑比原卷筒閘輪直徑增加了40mm,原有閘木進(jìn)行重新加工。
(3) 為增加聯(lián)接螺絲的緊固性,我們采用了先測(cè)量孔直徑,現(xiàn)加工螺絲的方法,保證了螺絲的配合尺寸,并采用厭氧膠技術(shù)提高了聯(lián)接的緊固性。
經(jīng)過(guò)全體施工人員的共同努力,歷時(shí)60h,圓滿完成了任務(wù)。經(jīng)現(xiàn)場(chǎng)測(cè)試,新卷筒運(yùn)行平穩(wěn),卷筒的徑向跳動(dòng)、閘輪的橢圓度、兩卷筒的纏繩累計(jì)誤差均滿足要求。
效益
此項(xiàng)改造工程共耗資萬(wàn)元,徹底解決了提升運(yùn)行中的不安全隱患,保證了全礦的安全生產(chǎn)。其經(jīng)濟(jì)效益相當(dāng)可觀,與改造前相比較：
（1） 節(jié)約了每年一次更換卷筒襯木的檢修時(shí)間,每次節(jié)約24h,
（2） 每年一次更換卷筒襯木的材料消耗,共3.5萬(wàn)元
（3） 節(jié)約了每月兩次加固卷筒的檢修時(shí)間,每月計(jì)16h,一年可節(jié)約檢修時(shí)間 192h,可創(chuàng)年利潤(rùn)164.2萬(wàn)元。
改造后,不到一年即可收回全部投資。同時(shí)還填補(bǔ)了我省提升機(jī)改造的一項(xiàng)空白。
改造后運(yùn)行狀況
改造后,從1995年1月至今,已經(jīng)運(yùn)行15年多,提升原煤420萬(wàn)t,運(yùn)行情況良好, 與改造前相比有以下優(yōu)點(diǎn):
(1) 完全消除了原來(lái)卷筒皮內(nèi)陷、裂縫現(xiàn)象,提升機(jī)運(yùn)行平穩(wěn),無(wú)雜音,保證了安全生產(chǎn)。
(2) 由于采用了一體的厚殼強(qiáng)支結(jié)構(gòu),完全消除了原卷筒的支撐件（工字鋼）斷裂現(xiàn)象,提高了整體強(qiáng)度。
(3) 由于采用固定繩槽,不存在繩槽磨損不一致現(xiàn)象,從而克服了原主、副卷筒運(yùn)行段纏繩不一致現(xiàn)象,提高了工作效率，
(4) 維修工作量大大降低,并節(jié)約了檢修時(shí)間,節(jié)省了維修費(fèi)用，
(5) 鋼絲繩的使用壽命有所延長(zhǎng)。由于采用固定繩槽,消除了原提升機(jī)運(yùn)行時(shí)鋼絲繩跳槽、咬繩的現(xiàn)象,使鋼絲繩運(yùn)行平穩(wěn),延長(zhǎng)了其使用壽命,并提高了整個(gè)提升系統(tǒng)的安全。
幾點(diǎn)體會(huì)
老式提升機(jī)的更新改造,是目前老礦井普遍面臨問(wèn)題,由于長(zhǎng)時(shí)間的運(yùn)行及礦井改、擴(kuò)建,原有的提升機(jī)大多已經(jīng)不能滿足安全生產(chǎn)的需要,運(yùn)行中都存在有不安全的隱患,必須進(jìn)行改造。但如何改造又是普遍存在的一個(gè)難題。更換提升機(jī)雖可解決問(wèn)題,但其費(fèi)用高、時(shí)間長(zhǎng)不符合煤礦實(shí)際生產(chǎn)的需要，而此次我礦的改造開(kāi)辟了一條捷徑,既解決了問(wèn)題又節(jié)省了大量的費(fèi)用和時(shí)間,具有一定的實(shí)用性和廣泛的推廣價(jià)值。
