文档介绍：摘要
本设计是通过对液压绞车工作原理、工作的环境和工作的特点进行分析,并结合实际,在进行细致观察后,对液压绞车的整体结构进行了设计,对组成的各元件进行了选型、计算和校核。本绞车由进口液压马达、进口平衡阀、常闭多片式制动器、离合器、卷筒、支承轴和机架等部件组成,还可根据需要设计阀组直接集成于马达配油器上,如带平衡阀、高压梭阀、调速换向阀或其它性能的阀组。在结构上具有紧凑、体积小、重量轻、外型美观等特点,在性能上则具有安全性好、效率高、启动扭矩大、低速稳定性好、噪音低、操作可靠等特点,在提升和下放工作中运转相当平稳,带离合器的绞车可实现自由下放工况,广泛适用于铁道机车和汽车起重机、船舶、油田钻采、地质勘探、煤矿、港口等各种起重设备中。

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 pute 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 pact,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 otive,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.
