Buffer device of elevator lift car

Abstract

The invention relates to the technical field of elevator equipment, in particular to a buffer device of an elevator lift car. The problem that an existing elevator is poor in buffering effect is solved. The device comprises an elevator pit body, an elevator lift car, a split type buffer and a buffer base, wherein the buffer base is provided with a plurality of arc-shaped sliding blocks through a sliding guide structure, and the arc-shaped sliding blocks are distributed in the circumferential direction to surround a conical channel; the circumferential outer sides of the arc-shaped sliding blocks and the buffer base are connected through a horizontal buffering structure, a buffer circular table is inserted into the conical channel, an arc-shaped groove is formed in the center of the upper end of the buffer circular table, and a safety air bag corresponding to the arc-shaped groove is arranged at the bottom of the elevator lift car; and the safety air bag is connected with an air inflation structure, a speed sensing module is arranged in the elevator lift car, the speed sensing module is connected with a MCU module, and the MCU module is connected with the inflating structure. The device has the advantages of being good in buffering and vibration reduction effects, small in rebound force, simple in structure, and easy to maintain.

Description

technical field [0001] The invention relates to the technical field of elevator equipment, in particular to an elevator car buffer device. Background technique [0002] Elevators are being more and more widely used in various buildings. The reliability and safety of elevators are closely related to the safety of passengers, so elevators need to be installed with necessary safety detection and safety protection devices, such as elevator buffers. The buffer is the last link of the elevator safety system, which acts as a buffer when the elevator breaks down or falls to the bottom in an accident. Thereby relieving the elevator or people in the elevator from direct impact. There are also many types of elevator buffers, but the existing elevator buffers have more or less shortcomings, or there are places that can be improved. For example, the most basic buffering effect of some buffers is not good, and the safety of the elevator cannot be guaranteed; some The structure of the b...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned scheme solves the problems of complex structure, poor cushioning effect and large rebound force of the existing elevator buffer to a certain extent, but there are still many deficiencies in this scheme, for example, the lack of multi-level buffering, and the inability to disperse the vertical impact force in time and many more
