Elevator buffering device

Abstract

The invention relates to an elevator buffering device. The elevator buffering device comprises an upper bottom plate and a lower bottom plate, at least three polyurethane buffers distributed in a geometric figure are arranged on the upper bottom plate, a hydraulic buffer is further arranged between the upper bottom plate and the lower bottom plate, the hydraulic buffer comprises a top cover connected with the bottom of the upper bottom plate, a plunger rod arranged below the top cover, a compression spring arranged around the plunger rod, a shell arranged below the compression spring and connected with the compression spring and a base arranged below the shell, a buffer pad is further arranged between the top cover and the upper bottom plate, a hollow guide pipe which divides the shell into an inner cavity and an outer cavity is arranged in the shell, a through throttling hole is formed in the side wall of the guide pipe, the lower end of the plunger rod is contained in the inner cavity, and hydraulic oil is arranged in the inner cavity. Compared with the prior art, the elevator buffering device uniform distribution effect is good, the defect that a traditional compression spring is only used for buffering work is overcome, the elevator buffering device is not easy to damage, can be found in time even if damaged, is durable, saves cost and the like.

Description

technical field [0001] The invention relates to an elevator accessory, in particular to an elevator buffer device. Background technique [0002] Lifting devices such as elevators are indispensable for urban life, and the safety of elevators has become a top priority for people to consider. The elevator buffer is the last link of the elevator safety system. It acts as a buffer when the elevator breaks down or crashes in an accident, so as to relieve the elevator or people in the elevator from direct impact. [0003] The existing elevator buffers with the same effect on the market mainly rely on compressing the internal spring to play a buffering role. However, the use of compression springs will have the following problems. First, when the compression spring has quality problems, it is difficult to find, and accidents are prone to occur ; And the volume is huge, the quality is heavy, and a single person cannot operate it. At the same time, when the elevator car fails, the e...

[0003] The existing elevator buffers with the same effect on the market mainly rely on compressing the internal spring to play a buffering role. However, the use of compression springs will have the following problems. First, when the compression spring has quality problems, it is difficult to find, and accidents are prone to occur ; And it is bulky and heavy, and cannot be operated by a single person

At the same time, when the existing elevator car fails, the existing elevator buffer is easy to deform the car due to the impact of the car on it, so that the elevator car cannot continue to be used, resulting in waste of resources
