本发明公开了一种具有可移动抓轨装置的接触网梯车及控制方法,具体涉及轨道小车抓轨防脱技术领域,包括梯车架和在钢轨轨头上滑动的滑移座,所述滑移座固定安装在梯车架的底面上。本发明通过卷绕机构的工作,钢绳开始卷绕进而将提升板提升,直至提升板运动至与防护栏杆底部横杆齐平的高度后,卷绕轴杆停止收卷后并使得棘轮停止转动,之后旋转气缸驱动着传动横杆上的制动棘爪转动至棘轮的表面上,实现对棘轮的限位,从而对卷绕轴杆锁紧,避免卷绕轴杆出现松动偏离,保证提升板的稳定制动机构对棘轮限位,实现对提升板的高度锁定,此时使用者站在提升板上,并由防护栏杆对其进行保护,不再需要人工攀爬至梯车架的顶部,省去了攀爬步骤。
The invention discloses a catenary ladder trolley with a movable rail grabbing device and a control method, and particularly relates to the technical field of rail grabbing and falling prevention of rail trolleys, the catenary ladder trolley comprises a ladder trolley frame and a sliding seat sliding on a steel rail head, and the sliding seat is fixedly installed on the bottom face of the ladder trolley frame. Through work of the winding mechanism, a steel rope starts to be wound to lift a lifting plate until the lifting plate moves to the height flush with a cross rod at the bottom of the protective barrier, a winding shaft rod stops winding and enables a ratchet wheel to stop rotating, and then a rotating air cylinder drives a braking pawl on a transmission cross rod to rotate to the surface of the ratchet wheel; the ratchet wheel is limited, so that the winding shaft rod is locked, loosening and deviation of the winding shaft rod are avoided, it is guaranteed that the ratchet wheel is limited by the stable braking mechanism of the lifting plate, the height of the lifting plate is locked, at the moment, a user stands on the lifting plate and is protected by the protective handrail, and the user does not need to climb to the top of the ladder frame any more; and the climbing step is omitted.
