液壓絞車設計

液壓絞車設計,液壓,絞車,設計 摘 要 本設計是通過對液壓絞車工作原理、工作的環(huán)境和工作的特點進行分析，并結(jié)合實際，在進行細致觀察后，對液壓絞車的整體結(jié)構進行了設計，對組成的各元件進行了選型、計算和校核。本絞車由進口液壓馬達、進口平衡閥、常閉多片式制動器、離合器、卷筒、支承軸和機架等部件組成，還可根據(jù)需要設計閥組直接集成于馬達配油器上，如帶平衡閥、高壓梭閥、調(diào)速換向閥或其它性能的閥組。在結(jié)構上具有緊湊、體積小、重量輕、外型美觀等特點，在性能上則具有安全性好、效率高、啟動扭矩大、低速穩(wěn)定性好、噪音低、操作可靠等特點，在提升和下放工作中運轉(zhuǎn)相當平穩(wěn)，帶離合器的絞車可實現(xiàn)自由下放工況，廣泛適用于鐵道機車和汽車起重機、船舶、油田鉆采、地質(zhì)勘探、煤礦、港口等各種起重設備中。 關鍵詞：液壓絞車；計算；校核；閥組 Abstract This design is to analyze the working principle，the working environment and the working characteristic of the hydraulic winch，and union reality，after the careful observation，I design the overall construction，and choose，compute and examine the various parts of the hydraulic winch. The winch is made up of the import hydraulic motor，import balancing valve，the brake of many pieces，coupling，reel，supporting axle and rack . Also we may design the valve group for the distributor of the motor，like with balancing valve，high-pressured shuttle valve，velocity modulation cross valve or other performance valve groups. The characteristic of the construction is compact ，small，light，beautiful and so on，the characteristic of the performance is safe，the high efficiency，the big start torque，the best low-speed stability characteristic，the low noise，the reliable operation. The winch is quite steadily in the work of promotion and relaxation ，The winch with the coupling also may release the things free ，It is popular to the railroad locomotive ，the auto hoist，the ships， the oil field of drills picks，the geological prospecting，the coal mine，the harbor and the each kind of hoisting equipment. Key words：Hydraulic winch；Computation；Examination；Valve group
