Buffer structure at bottom of elevator

Abstract

The invention relates to the technical field of elevator equipment, and discloses an elevator bottom buffer structure which comprises a base, fixing plates are fixedly installed on the two sides of the base, a bottom plate is fixedly connected to the other ends of the fixing plates, telescopic springs are fixedly connected to the upper surface of the bottom plate, and a contact plate is fixedly installed on the upper surfaces of the telescopic springs. A tank body is fixedly mounted at the top of the base, an air bag is fixedly mounted in an inner cavity of the tank body, a polymer plate is fixedly mounted at the top of the air bag, and a metal plate is fixedly mounted at the top of the polymer plate. The air bag assembly is installed at the bottom of the equipment, the air bag assembly is used in cooperation with the air outlet device, air leakage of an air bag can be achieved through pressure of a telescopic rod when an elevator falls, counter-acting force is provided, then safety of the elevator during falling can be guaranteed, good buffering is provided, meanwhile, springback fatigue of a spring can be reduced, and the service life of the elevator is prolonged. The service life of the spring is prolonged.

Description

technical field [0001] The invention relates to the technical field of elevator equipment, in particular to an elevator bottom buffer structure. Background technique [0002] Elevator refers to a permanent transportation device that serves several specific floors in a building, and its car runs on at least two rows of rigid tracks perpendicular to the horizontal plane or with an inclination angle of less than 15° to the plumb line. There are also step type, the tread plate is installed on the crawler to run continuously, commonly known as escalator or moving walk. Fixed lift equipment serving specified floors. A vertical lift has a car running between at least two rows of rigid guide rails that are vertical or inclined at an angle of less than 15°. The size and structure of the car are convenient for passengers to enter and exit or load and unload goods. It is customary to use elevators as a general term for vertical transportation tools in buildings regardless of their d...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a buffer structure at the bottom of an elevator, which has a good buffering effect, can disperse the force, and at the same time can reduce the force of the spring, reduce the pressure of the spring, and at the same time ensure that the elevator The advantage of being able to receive a large reaction force when falling, solves the problem that the existing elevator buffer has a poor bearing capacity during use, which leads to elastic fatigue of the buffer after long-term use, which in turn leads to its failure in use. There are certain safety hazards in the process. Most of the existing elevator buffers use hydraulic rods to work with high-strength springs during use, resulting in the possibility of bending the hydraulic rods when they fall from a high altitude during use, and cannot The issue of ensuring the safety of passengers
