The invention discloses an elevator emergency hydraulic buffer capable of preventing reset performance from losing efficacy, and relates to the technical field of hydraulic buffers, in particular to an elevator emergency hydraulic buffer capable of preventing reset performance from losing efficacy, which comprises a cylinder body, an electromagnetic ring fixedly sleeved outside the cylinder body, and a limiting strip fixedly sleeved outside the cylinder body, a supporting ring is movably arranged outside the barrel in a sleeving mode, and a metal ring is fixedly connected to the bottom of the supporting ring. According to the elevator emergency hydraulic buffer capable of preventing the reset performance from losing efficacy, a supporting ring is arranged above an electromagnetic ring, the supporting ring can be fixed to a proper position during emergency use through cooperation of a metal ring, meanwhile, the upper face of the supporting ring is connected with a reset plate through a standby spring, and through cooperation of a metal block and an electromagnetic block, the reset performance can be effectively improved. When the internal reset spring fails, the standby spring can play a role of a standby reset spring to assist the piston connecting rod in resetting, and normal work of the device is guaranteed.

    本发明公开了一种可防止复位性能失效的电梯应急液压缓冲器,涉及液压缓冲器技术领域,具体为一种可防止复位性能失效的电梯应急液压缓冲器,包括筒体,所述筒体的外部固定套装有电磁环,所述筒体的外部固定套装有限位条,所述筒体的外部活动套装有支撑环,所述支撑环的底部固定连接有金属环。该可防止复位性能失效的电梯应急液压缓冲器,使支撑环设置在电磁环的上方,利用金属环的配合,在紧急使用时能够将支撑环固定在合适的位置,同时在支撑环的上面通过备用弹簧连接复位板,利用金属块和电磁块的配合,方便在内部的复位弹簧失效时,备用弹簧会起到备用复位弹簧的作用,辅助活塞连杆复位,保证装置的正常工作。
