The invention relates to the technical field of climbing machinery, in particular to a locking mechanism which comprises a shell, a brake pin shaft and a locking shaft, the shell is internally provided with a first channel and a second channel which are communicated with each other and form a set angle, the brake pin shaft is installed in the first channel and can move along the first channel, and the locking shaft is installed in the second channel. The brake pin shaft is arranged on the shell so as to be switched between an unlocking state of contracting relative to the shell and a locking state of stretching relative to the shell, and a brake hole is formed in the peripheral face of the brake pin shaft. The locking shaft is installed on the second channel, the locking shaft is suitable for being switched between the locking position and the avoiding position along the second channel, the invention further relates to a lifting device and a lifting system comprising the locking mechanism, the situation that the lifting device cannot stop due to the fact that the lifting device and the lifting system break down suddenly in the lifting process is solved, and the safety of the lifting device is improved. Especially under the condition that the vehicle cannot be parked in the ascending process, the vehicle body is parked through the locking function of the locking mechanism, and personnel and property losses are avoided to the maximum extent.

    本发明涉及爬升机械技术领域,尤其涉及一种锁止机构,包括壳体、制动销轴和锁止轴,壳体内部设置有相互连通且呈设定角度的第一通道和第二通道,制动销轴安装于第一通道,制动销轴可沿着第一通道移动,以在相对所述壳体收缩的解锁状态和相对所述壳体伸出的锁止状态之间切换,制动销轴的外周面设置有制动孔;锁止轴安装于第二通道,锁止轴适于沿着所述第二通道在锁止位置和避让位置切换,本发明还涉及含有该锁止机构的升降装置和升降系统,解决了升降装置及升降系统在升降过程中突发故障,造成的升降设备无法停车的情况,尤其是上升过程中的无法停车情况,利用锁止机构的锁止功能将车体停住,最大限度的避免的人员和财产损失。
