Elevator buffer

Abstract

The invention discloses an elevator buffer. The elevator buffer comprises a collided head and a body. The elevator buffer is characterized in that the body is movably connected with the collision head through an axis; a buffering head is closely attached and fixed to the upper portion of the collision head, and a wood buffering head is adopted as the buffering head and has good buffering performance and hit performance; the bottom end of the body is fixed to the contact ground; the body is further fixed to the contact ground through a support, wherein one end of the support is welded to the lower middle section of the body, and the other end of the support is fixed to the contact ground through a fixing piece; and a hydraulic buffer is adopted as the buffer. The elevator buffer has the advantages that firstly, the running performance is stable, and the buffering effect can be guaranteed; secondly, the elevator buffer is protected, and the situation that the elevator buffer is stressed, consequently, the elevator buffer is laterally inclined or topples down, and the buffering function is lost is prevented; thirdly, the space needed for operation is small; and fourthly, raw materials needed for the hydraulic buffer are oil or other liquid, and therefore compared with other buffers, the manufacturing cost is much lower.

Description

technical field [0001] The invention relates to an elevator buffer and belongs to the technical field of elevator safety protection. Background technique [0002] Nowadays, elevators are indispensable no matter in shopping malls, residences or hospitals, etc. It is also common for elevators to break down. After a long time, elevators stop running due to minor problems. You can wait for professionals to solve the problem. Sometimes because there is no maintenance, Once the elevator wire rope is disconnected, the elevator may directly and rapidly descend. Currently, the commonly used buffers for buffering can play a certain buffering effect on the elevator, but the stalled and falling elevator car and the buffer When in contact, the vibration and impact force generated by the impact can be directly transmitted to the elevator car, so it is easy to cause casualties to passengers in the elevator car. At the same time, due to the limitation of its structure, the buffer stroke of...

[0002] Nowadays, elevators are indispensable no matter in shopping malls, residences or hospitals, etc. It is also common for elevators to break down. After a long time, elevators stop running due to minor problems. You can wait for professionals to solve the problem. Sometimes because there is no maintenance, Once the elevator wire rope is disconnected, the elevator may directly and rapidly descend. Currently, the commonly used buffers for buffering can play a certain buffering effect on the elevator, but the stalled and falling elevator car and the buffer When in contact, the vibration and impact force generated by the impact can be directly transmitted to the elevator car, so it is easy to cause casualties to passengers in the elevator car

At the same time, due to the limitation of its structure, the buffer stroke of the traditional elevator buffer device is small, so the buffer performance is poor

Moreover, the buffers commonly used at present are not fixed by brackets, and there are cases where the buffer is tilted under pressure and cannot play the role of buffering.
