The invention relates to a leveling railway electrification construction ladder truck which comprises a truck base, a rail grabbing device arranged below the truck base and an operation platform arranged above the truck base, the operation platform is connected with the truck base through an air cylinder, and a groove is formed in the side face of the operation platform in an embedded mode. When the ladder truck inclines to a certain degree, the sliding block is triggered to slide in the horizontal sliding rail and extrude the pneumatic switch, and after the pneumatic switch is pressed, under the pressure action of the operation platform, air in a cylinder barrel of the air cylinder is rapidly discharged through the pressure relief pipe and enters the groove, so that the ladder truck is prevented from falling off. And air in the air cylinder is exhausted, so that the air cylinder is automatically shortened, the gravity center of the ladder truck is lowered, the stability of the ladder truck is improved, and the risk of high-altitude construction of operators is reduced as much as possible.

    本发明涉及一种可调平铁路电气化施工梯车,包括车底座、设置在所述车底座下方的抓轨器以及设置在所述车底座上方的操作平台,所述操作平台与车底座之间通过气缸连接,所述操作平台的侧面嵌入设有凹槽,所述凹槽内滑动设有缓冲杆,本发明梯车倾斜到一定程度时,触发滑动块在水平滑轨内滑动并挤压气动开关,气动开关按压后,在操作平台的压力作用下,气缸缸筒内的空气通过泄压管快速排出并进入到凹槽中,使得缓冲板从操作平台的侧面伸出,起到防护作用,且因为气缸内空气的排出,使得气缸自动缩短,降低梯车的重心,提高梯车的稳定性,尽可能减少操作人员高处施工的风险。
