摘　　要：常见的便梁纵移人力推车只能运行于直线段的钢轨上,对于曲线段铁轨无法使用,给施工带来极大不便。提出一种适用于曲线钢轨的便梁纵移人力推车,负重轮上方焊接一个旋转部,旋转部由钢槽、钢封环、旋转板、竖向钢板和顶板构成,组装时,钢槽内部布满钢珠、旋转板置于钢槽内部并压在钢珠上、再把钢封环焊接于钢槽的敞口上。旋转板与钢槽之间非常容易发生相对旋转,从而实现车架与负重轮的自由旋转。所提推车设备简单、行走速度快、综合造价低廉,解决曲线钢轨区域的便梁纵移问题,为铁路工程施工提供简便实用设备。The common manual trolley with longitudinal movement of the beam can only run on the rail of the straight line section,and the rail of the curve section can not be used,which brings great inconvenience to the construction.In this paper,a kind of longitudinally moving manual trolley suitable for curved rail is proposed.A rotating part is welded above the load wheel,which is composed of steel groove,steel sealing ring,rotary plate,vertical steel plate and roof plate.Steel groove is covered with steel balls,the rotating plate is placed inside the steel groove and pressed on the steel ball,and then the steel sealing ring is welded to the open of the steel groove.The relative rotation between the rotating plate and the steel groove is very easy to realize the free rotation between the frame and the weight-bearing wheel.The trolley has the advantages of simple equipment,fast walking speed and low comprehensive cost,which solves the problem of longitudinal displacement of convenient beam in curved rail area,and provides simple and practical equipment for railway engineering construction.
