Spring shock absorber for elevator and using method thereof

Abstract

The invention discloses a spring shock absorber for an elevator. The spring shock absorber for the elevator comprises a lift car body and an elevator shaft, the lift car body is arranged in the elevator shaft in a matched mode, a bearing supporting plate is arranged in the bottom space of the elevator shaft in a horizontal state, and an air cushion is arranged on the upper plate face of the bearing supporting plate; a main body buffer spring is correspondingly arranged in a sleeve cavity of each supporting sleeve, a side edge horizontal buffer spring is further correspondingly arranged on a column body of each horizontal sliding column in a sleeved mode, and a side edge vertical buffer spring is further correspondingly arranged on a rod body of a linkage lower pull rod in a sleeved mode; and a synchronous downward moving column is further vertically fixed to the center of the upper surface of a pull-down walking block, a trapezoidal clamping head is correspondingly clamped between every two adjacent trapezoidal clamping teeth in the multiple trapezoidal clamping teeth, the trapezoidal clamping heads are movably limited in positioning short cylinders in a matched mode, and reset jacking springs are further arranged in cylinder cavities of the positioning short cylinders. According to the spring shock absorber for the elevator, a good buffering and damping effect is brought to personnel, and the safety of the whole equipment is guaranteed.

Description

technical field [0001] The invention relates to the technical field related to elevator equipment, in particular to a spring shock absorber for an elevator and a method for using the same. Background technique [0002] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, used for multi-storey buildings to take advantage of people or carry goods. A vertical elevator has a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use elevator as a general term for vertical transportation in buildings regardless of its driving mode. According to the speed, it can be divided into low-speed elevators, fast elevators and high-speed elevators. Hydraulic elevators began to appear in the mid-19th century and are still used in low-rise buildings today. In 1852, E.G...

AI Technical Summary

Problems solved by technology

[0005] With the development of buildings, elevators are used more and more, and the cases of elevator failures are gradually increasing. There are often elevators that often fall, resulting in the human body being unable to withstand the impact of the elevator falling at a high speed and dying.

[0006] The safety buffer device is an elevator safety device that provides the last safety protection, but the buffering and shock absorption effect of the safety buffer device in the prior art is not good. In the case of block upward "jiggling" phenomenon, the safety of the equipment cannot be guaranteed, and this problem needs to be designed
