基于 PLC 的多層停車場(chǎng)的研究與設(shè)計(jì)
1.立體停車庫(kù)發(fā)展概況
立體停車庫(kù)設(shè)備的應(yīng)用已有 30 多年的歷史了發(fā)展較早、較好的有日本、韓國(guó)、臺(tái)灣省、德國(guó)等眾所周知,我國(guó)經(jīng)濟(jì)在經(jīng)歷了近 30 年的高速增長(zhǎng)之后,大眾對(duì)生活質(zhì)量的要求日益提高,“衣食住行”中的“行”提高到一個(gè)新的高度。隨之而來(lái)的交通方面的情況也日加緊張,而這包含了動(dòng)態(tài)與靜態(tài)兩個(gè)方面。如同城市中由平房改建成高樓大廈一樣,停車也從平面轉(zhuǎn)向立體化停放,立體停車在靜態(tài)交通中已經(jīng)占有越來(lái)越重要的地位。立體停車庫(kù)與傳統(tǒng)的地下車庫(kù)相比,在許多方面都顯示出優(yōu)越性首先是節(jié)地優(yōu)勢(shì),以往的地下車庫(kù)由于要留出足夠的行車通道,平均一輛車就要占據(jù) 40 平方米的面積,而如果采用雙層立體停車庫(kù),可使地面的使用率提高 80%—90%,如果采用地上多層(21 層)立體式車庫(kù)的話,50 平方米的土地面積上便可存放 40 輛車,可以節(jié)省土地資源和減少土建開發(fā)成本。例如北京印度尼西亞駐華大使館未建多層立體停車庫(kù)前平面只能放五輛車,現(xiàn)建成三層立體升降橫移類停車庫(kù)后,能停放 13 輛車,基本能滿足駐華大使館要求。人們普遍認(rèn)為停車設(shè)備行業(yè)發(fā)展前景良好,并已被譽(yù)為 21 世紀(jì)最熱門的行業(yè)之一。
2.升降橫移式立體停車庫(kù)概念
立體停車設(shè)備目前已提供的共有 9 大類:升降橫移類(PSH)、簡(jiǎn)易升降類(PJS)、垂直升降類(PCS)、垂直循環(huán)類(PCX)、平面移動(dòng)類(PPY)、巷道堆垛類(PXD)、多層循環(huán)類(PDX)、水平循環(huán)類(PSX)、汽車升降機(jī)(PQS),又有幾十種規(guī)格,可以適用于不同的空間、場(chǎng)地條件,是一種具有高安全性,高可靠性、高效率的自動(dòng)化成套設(shè)備。在以上 9 種類型尤以升降橫移類(PSH)立體停車庫(kù)應(yīng)用最為廣泛。采用以載車板升降或橫移存取車輛的立體停車設(shè)備的停車庫(kù)叫做升降橫移類停車庫(kù)。升降橫移式立體停車庫(kù)采用模塊化設(shè)計(jì),每單元可設(shè)計(jì)成兩層、三層、四層、五層、半地下等多種形式,車位數(shù)從幾個(gè)到上百個(gè)。由于升降橫移類立體停車庫(kù)的型式比較多,規(guī)??纱罂尚?,對(duì)場(chǎng)地的適應(yīng)性較強(qiáng),因此,采用這類設(shè)備的停車庫(kù)十分普遍。其工作原理為:每個(gè)車位均有載車板,所需存取車輛的載車板通過(guò)升、降、橫移運(yùn)動(dòng)到達(dá)地面層,駕駛員進(jìn)入車庫(kù),存取車輛,完成存取過(guò)程。上層車位或下層車位需通過(guò)中間層橫移出空位,將載車板升或降到地面層,駕駛員才可進(jìn)入車庫(kù)內(nèi)將汽車開進(jìn)或開出車庫(kù)。
3.三層升降橫移式立體停車庫(kù)系統(tǒng)設(shè)計(jì)
升降橫移式立體停車庫(kù)是一種比較典型的跨學(xué)科機(jī)電一體化產(chǎn)品,集機(jī)械、電子、信息技術(shù)于一體。升降橫移式立體停車庫(kù)主要由鋼結(jié)構(gòu)部分、載車板部分、傳動(dòng)系統(tǒng)、控制系統(tǒng)、安全防護(hù)系統(tǒng) 5 部分組成,如圖 2 所示。三層機(jī)械停車設(shè)備是升降橫移類機(jī)械式停車設(shè)備的一個(gè)類型,此類型車庫(kù)每組設(shè)備的中間層、地面層都留有空車位,地面層只做橫移運(yùn)動(dòng),地上二層既做橫移運(yùn)動(dòng)又做升降運(yùn)動(dòng),地上三層只做升降運(yùn)動(dòng)。運(yùn)行時(shí),地面層可直接存取車;地上二層存取車,需通過(guò)地面層相對(duì)應(yīng)的載車臺(tái)橫移讓出空位后,升降到達(dá)地面層實(shí)現(xiàn);地上三層存取車時(shí),需通過(guò)地上二層、地面層相對(duì)應(yīng)的載車臺(tái)同時(shí)橫移讓出空位后,升降到達(dá)地面層實(shí)現(xiàn)。其運(yùn)動(dòng)的總原則是:升降復(fù)位平移不復(fù)位。立體停車庫(kù)按用戶所要求的停車規(guī)格設(shè)計(jì),運(yùn)行方式分自動(dòng)和手動(dòng)兩種,可通過(guò)開關(guān)切換,在車庫(kù)正常運(yùn)行時(shí)使用自動(dòng)方式,在設(shè)備維修和調(diào)試時(shí)可使用手動(dòng)方式。自動(dòng)方式和手動(dòng)方式均采用 PLC 可編程控制器控制,因此可保證設(shè)備在任何方式下的安全運(yùn)行。設(shè)備有多種安全裝置可確保人車安全,如安全防墜裝置,限位及防過(guò)卷裝置,斷電自動(dòng)剎車制動(dòng)裝置,錯(cuò)斷相保護(hù)等。
