Self-adaption elevator buffer with feedback

Abstract

The invention discloses a self-adaptive elevator buffer with feedback, which comprises an oil cylinder. A piston is arranged inside the oil cylinder. The piston is fixedly connected to a baffle above the oil cylinder through a piston rod. The lower end of the baffle is connected to the upper end of the oil cylinder. A spring is arranged between them; an installation box is arranged on the upper end of the baffle, a programmable PLC controller is arranged in the installation box, and a wire inlet hole is arranged on the right side of the installation box; a strike plate is arranged on the upper end of the installation box, The lower end of the right side of the strike plate is provided with a speed detection module, and the upper end of the strike plate is provided with a buffer pad. The new type can change the damping coefficient of the damping hole in real time according to the speed feedback when the elevator bridge car collides through the form of quantitative buffering and variable buffering, so as to achieve an adaptive buffering process and avoid existing buffers that are difficult to meet different collision speeds. disadvantages, so that buffering is a more reasonable gradient process.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an adaptive elevator buffer with feedback. Background technique [0002] The buffer is installed at the bottom of the elevator shaft. When the elevator car or the counterweight falls, it can play the role of final buffering, stopping and protection, so as to prevent the car or the counterweight from directly hitting the bottom. The buffering effect of the elevator buffer is currently It is not good enough. It generally realizes the buffering of the elevator through springs or hydraulic damping, but due to the characteristics of the spring or damping itself, the buffering strength is fixed, and the buffering strength cannot be automatically adjusted for different elevator speeds. As we all know, the elevator car in When falling at different heights, the speed when it contacts the buffer is different, so it is obviously inappropriate to reduce the buffering of the elevator with a...

[0002] The buffer is installed at the bottom of the elevator shaft. When the elevator car or the counterweight falls, it can play the role of final buffering, stopping and protection, so as to prevent the car or the counterweight from directly hitting the bottom. The buffering effect of the elevator buffer is currently It is not good enough. It generally realizes the buffering of the elevator through springs or hydraulic damping, but due to the characteristics of the spring or damping itself, the buffering strength is fixed, and the buffering strength cannot be automatically adjusted for different elevator speeds. As we all know, the elevator car in When falling at different heights, the speed when it contacts the buffer is different, so it is obviously inappropriate to reduce the buffering of the elevator with a fixed buffering strength, so there is an urgent need for a buffer that can automatically adapt to the falling speed of the elevator
