The invention discloses an automatic lifting steel rail hanging anti-slip device for a shield construction tractor. The automatic lifting steel rail hanging anti-slip device comprises an air cylinder and a rail clamping double-hook assembly. The rail clamping double-hook assembly is hinged to a front end plate of a cab of the tractor; the two ends of the air cylinder are hinged to the front end plate of the tractor cab and the rail clamping double-hook assembly; the rail clamping double-hook assembly is provided with clamping grooves corresponding to the two steel rails respectively, the two side walls of each clamping groove are provided with rail clamping plates respectively, a big-end-down wedge-shaped gap is formed, and the top size of each wedge-shaped gap is smaller than the width size of the upper plane of the corresponding steel rail. The device is simple in structure, cannot directly damage the steel rail, is provided with the flexible clamping rail, is small in damage to the steel rail, is low in maintenance cost of the steel rail, and enables driving to be safer and more reliable.

    本发明公开了一种用于盾构施工牵引车的自动升降挂钢轨防溜装置,包括气缸及卡轨双挂钩组件;所述的卡轨双挂钩组件铰接在牵引车司机室前端板上;气缸的两端分别与连接牵引车司机室前端板和卡轨双挂钩组件铰接;卡轨双挂钩组件对应于两钢轨分别设有一个卡槽,卡槽的两侧壁上分别设有一轨道夹板,形成上小下大的楔形间隙,楔形间隙顶部尺寸小于钢轨上平面宽度尺寸。本发明结构简单,不会直接破坏钢轨,带柔性卡轨,对钢轨的破坏性小,维护钢轨成本低,且使得行车更安全可靠。
