The invention relates to the technical field of service dollies, and discloses a lower-layer circuit breaker drawing and fixing structure for a lifting service dolly, which comprises a lifting service dolly, a tray is slidably connected in the lifting service dolly, the tray performs lifting motion through a hydraulic cylinder, and lock rods are symmetrically slidably connected to the bottom end of the tray. Fixing plates are clamped on the two sides of the tray, a baffle is rotationally connected to the side wall of the tray above the fixing plates, a supporting plate is fixedly connected to the top ends of the fixing plates, and a hook ring is rotationally connected to the bottom end of the supporting plate. The lifting service trolley can be conveniently mounted and dismounted, so that when a circuit breaker below needs to be taken out, the lifting service trolley can quickly work, meanwhile, the lifting service trolley can move and guide the whole lifting service trolley to conveniently form transverse limiting with a circuit breaker cabinet, and during working, the lifting service trolley can be stably linked with the circuit breaker cabinet by rotating a shackle in the lifting service trolley structure, so that the working efficiency is improved. And finally, the circuit breakers above and below the lifting service trolley can be stably mounted and taken out.

    本发明涉及服务小车技术领域,且公开了一种升降服务小车用下层断路器抽拉固定结构,包括升降服务小车,升降服务小车的内部滑动连接有托盘,托盘通过液压缸进行升降运动,托盘的底端对称滑动连接有锁杆,托盘的两侧均卡放有固定板,固定板上方的托盘侧壁转动连接有挡板,固定板的顶端固定连接有支撑板,支撑板的底端转动连接有钩环。本发明能够便捷的安装和拆卸,从而当需要取出下方断路器时,可快速的进行工作状态,同时能够对整个升降服务小车进行移动导向,便于与断路器柜形成横向限位,工作时,还能够通过转动该结构中的钩环与断路器柜进行稳定连锁,最终使得该升降服务小车能够稳定安装的取出上下方的断路器。
