The invention discloses a bogie lifting device which comprises a base and a lifting seat located above the base, and a lifting mechanism used for driving the lifting seat to move upwards and a locking mechanism used for locking the lifting seat are arranged between the base and the lifting seat. The lifting mechanism comprises two first swing rods and two second swing rods which are rotationally connected to the upper surface of the base, the first swing rods and the second swing rods which are adjacent left and right are distributed in a crossed mode, and the upper ends of the first swing rods and the upper ends of the second swing rods are rotationally connected to the lower surface of the lifting base. According to the lifting device, the locking mechanism is arranged so that the lifting base can be conveniently locked after the lifting base ascends, and the safety performance of the device is effectively improved; and by arranging the lubricating mechanism, lubricating oil can be conveniently sprayed to the two ends of the first swing rod and the two ends of the second swing rod when the base and the lifting base are folded, the situation that the device is stuck after being used for a long time is prevented, and the safety performance of the device is further improved.
本发明公开了一种转向架举升装置,包括底座,以及位于底座上方的举升座,所述底座和举升座之间设置有用于驱动举升座向上移动的升降机构,以及用于锁定举升座的锁定机构,所述升降机构包括转动连接于底座上表面的两个第一摆杆和两个第二摆杆,左右相邻的第一摆杆和第二摆杆之间交叉分布,所述第一摆杆和第二摆杆的上端均转动连接于举升座下表面。本发明,通过设置锁定机构,以便于在举升座上升后对其进行锁定,有效地提高了装置的安全性能;通过设置润滑机构,以便于在底座和举升座折叠时对第一摆杆和第二摆杆的两端喷上润滑油,防止设备在长时间使用下发生卡顿的情况,进一步的地升了装置的安全性能。
