The invention relates to the field of elevators, in particular to an elevator shaft buffering system which comprises a lift car arranged in an elevator shaft, a buffering base is arranged at the bottom of the elevator shaft, a water pressure buffering mechanism is further arranged at the bottom of the elevator shaft and provided with a water tank, and a first water filling cavity is formed in the water tank and the elevator shaft. The water tank and the exterior of the elevator shaft form a second water filling cavity, the first water filling cavity and the second water filling cavity communicate with each other, the depth of the second water filling cavity is higher than that of the first water filling cavity, a water filling opening is formed in the tank wall of the water tank, and a first floating plate is horizontally arranged in the first water filling cavity. According to the elevator car falling buffering device, falling of the elevator car is buffered for the first time through the buffering base, falling of the elevator car is buffered for the second time through the buffering base, the buffering effect is improved, meanwhile, the service life of the buffering base is prolonged, the situation that the buffering effect cannot be achieved due to performance deficiency caused by only using the buffering base is avoided, and it is guaranteed that personnel in the elevator car are effectively protected.

    本发明涉及电梯领域,具体是涉及一种电梯井缓冲系统,包括设置在电梯井中的轿厢,电梯井的底部设有缓冲底座,电梯井的底部还设有水压缓冲机构,水压缓冲机构设有水槽,水槽与电梯井的内部形成第一充水腔,水槽与电梯井的外部形成第二充水腔,第一充水腔和第二充水腔相互连通,第二充水腔的深度高于第一充水腔的深度,水槽的槽壁上开设有充水口,第一充水腔中水平设有第一浮板,本发明通过水槽中充水的方式,对轿厢的下坠进行了一次缓冲,再通过缓冲底座对轿厢的下坠进行了二次缓冲,提高了缓冲效果的同时,也提高了缓冲底座的寿命,避免只使用缓冲底座,而造成性能缺失无法起到缓冲效果的情况,保证对轿厢内人员的有效保护。
