The invention provides a locking structure for a lifting machine. The locking structure comprises a locking block, a locking plate and a driving rod, wherein the locking block is rotatably arranged on a pulley, the locking plate and the driving rod are arranged along the moving direction of the pulley, the locking plate is provided with a locking hole, the end part of the locking block extends into the locking hole, and the driving rod is used for pushing the locking block to enable the end part of the locking block to leave the locking hole. According to the locking structure for the lifting machine, the end part of a clamping block extends into the locking hole, so that the pulley is clamped and does not slide down, the weight of the pulley falls on the locking plate through the locking block; when the pulley is lifted, the driving structure does not need to be stressed, so that the service life of the driving structures such as a hydraulic oil cylinder is prolonged; and when the hydraulic oil cylinder breaks down, the end part of the clamping block extends into the locking hole, so that the pulley does not fall off, and the safety is ensured.
本发明提供一种用于举升机的锁止结构,包括:锁块、锁止板和驱动杆;所述锁块可转动的设于滑车上,所述锁止板和驱动杆均沿所述滑车的运动方向设置,所述锁止板设有锁止孔,所述锁块的端部伸入所述锁止孔中,所述驱动杆用于推动所述锁块,使所述锁块的端部离开所述锁止孔。本发明公开的一种用于举升机的锁止结构,卡块的端部伸入锁止孔中,使滑车卡住,不会下滑,而且,滑车的重量,通过锁块落在锁止板上,托举时,无需驱动结构受力,增加了液压油缸等驱动结构的寿命,当液压油缸出现故障时,由于卡块的端部伸入锁止孔中,使滑车不会掉落,保证了安全性。
