毕业设计：薄煤层采煤工作面电缆拖移系统

摘   要

       薄煤层采煤工作面电缆拖移系统，是薄煤层连续采煤机配套的附属装置，其主要作用就是当采煤机沿工作面运动时，拖动采煤机的驱动电缆和除尘用的水管。当采煤机前行时，拖移装置就下放电缆；当采煤机后退时，拖移装置就同步地收回电缆，并且保证电缆的收放速度与采煤机同步。

       目前，拖移装置主要是缠绕绞车的方式。不过，本设计内容将采用一种新的方式：改固定式缠绕绞车为往复移动的小车，采用齿轮-销排传动方案，车上载有四个滑轮的滑轮组，另一端是固定的四个滑轮组，两个滑轮组之间绕有电缆，通过小车的运动改变两滑轮组之间的距离，从而实现电缆的收放。

       本方案由中国矿业大学赵继云教授提出并亲自主导，聚集了老师和许多专家的智慧，具有更卓越的性能，前途光明。但由于拖移系统开发是一个复杂的过程，需做到机械和电子控制的完美结合，才能设计出一个性能良好的拖移系统。

ABSTRACT

    The cable-drag system of the thin coal seal is a subsidiary device of the thin seam shearer. Its main function is dragging the drive cable and dust water pipe of the shearer when it moves along the working surface. The drag system lays down the cable when the shearer moves forward. When the shearer moves back, it withdraws the cable in order to make sure the speed of cable is coordinate to the shearer.

       At present, the drag device is mainly using the form of winch. However, a new approach will be adopted in this design: change the fixed winding winch to reciprocating tram, using gear-peg program, carrying four pulleys of the pulley group, and there is four pulley groups at the other side. Twining cable between the two pulley groups, using the movement of the tram to change the distance between the groups, thus realizing the function of lengthen and shorten of the cable.

       This program is put forward and lead by professor zhao ji yun of China university of mining and technology, gathered many teachers and experts, a better performance and a bright future will be showed. However, due to the development of the drag system is a complex process, it needs the perfect combination of the mechanical and electronic control, and then a superior drag system can be designed.
