Abstract

The invention discloses an elevator fall buffer device, which belongs to the technical field of elevator safety. It includes a buffer piston, a base plate and a buffer pad, the buffer piston is fixed on the base plate, the buffer pad is fixed on the bottom of the base plate, the buffer piston includes an upper spring piston rod, a lower spring piston rod, a piston cavity, an upper piston and The lower piston, the upper spring piston rod is connected with the upper piston, the lower spring piston rod is connected with the lower piston, the upper piston and the lower piston are arranged in the piston chamber, and a return spring is arranged between the upper piston and the lower piston. The upper piston and the lower piston are provided with oil holes, and both the upper piston and the lower piston are in sealing contact with the piston cavity through the sealing ring. The elevator fall buffer device of the present invention can achieve the purpose of buffering after the elevator accidentally falls, has good buffer effect and simple structure.

Description

technical field [0001] The invention relates to an elevator fall buffer device and belongs to the technical field of elevator safety. Background technique [0002] Elevator safety has become the focus of everyone's attention. Generally speaking, elevators have three safety lines of defense: [0003] The first layer of defense: wire ropes, generally speaking, there are at least 5 elevator wire ropes. With the strength of the wire rope, it is not a problem to break 1-2 wire ropes. However, in a static state, a wire rope can pull a car. [0004] The second layer of defense: car safety gear, even if the wire rope is completely broken, the elevator will fall. But when the falling speed exceeds the rated speed, the speed limiter will stop it, and the car safety gear will act jointly to lock the car on the guide rail to prevent the next fall. [0005] The third layer of defense: buffer device, there will be a buffer device on the buffer ground to reduce the impact force. If th...
