The bogie lifting hydraulic pressurizing device comprises a top plate, two sliding blocks are slidably connected to the inner wall of a sliding opening formed in the top end of the top plate, the bottom ends of the sliding blocks are both fixedly connected with side plates, clamping lifting mechanisms are arranged on one sides of the side plates, and the clamping lifting mechanisms are used for fixing and lifting a bogie. An auxiliary block is connected with a stroke column, after a linkage column penetrates through a clamping block and a connecting strip, an electric pressurizing oil cylinder pushes the connected clamping block and the auxiliary block to synchronously get close, the clamping block gets close to clamp a transmission shaft between steering wheels on a bogie, and then the auxiliary block is pushed to make contact with the transmission shaft; the connecting bolts on the rotary fixing plate are connected with the corresponding auxiliary blocks and the corresponding clamping blocks correspondingly to fix the auxiliary blocks, the second motor drives the worm to drive the worm gear to rotate, the worm gear ascends along the second lead screw, the lifting plate drives the bogie to ascend and lift, the bogie is convenient to overhaul, and the overhaul efficiency is improved.

    本发明公开了一系簧为人字簧的转向架托举液压加压装置,包括包括顶板,顶板顶端开设的滑动口的内壁滑动连接有两个滑块,滑块的底端均与侧板固定连接,侧的一侧均设有夹紧托举机构,夹紧托举机构用于固定和托举转向架,本发明通辅助块与行程柱连接,联动柱穿过夹紧块和连接条后,电动加压油缸推动连接的夹紧块,辅助块同步靠近,夹紧块靠近对转向架上转向轮之间的传动轴进行夹紧,再推动辅助块与其接触后,转动固定板上的连接螺栓分别与对应的辅助块和夹紧块连接,对辅助块进行固定,第二电机驱动蜗杆带动蜗轮转动,蜗轮沿第二丝杆上升,托举板带动转向架上升托举,便于转向架的检修,提高了检修效率。
