Problems solved by technology

The installation of this device needs to occupy a large amount of machine room and hoistway space. At the same time, this device mainly prevents the horizontal shaking of the sling due to the influence of the wind, but it still does not solve the problem of vertical shaking of the car caused by people entering and leaving the car. solve

Embodiment Construction

[0054] like figure 1 As shown, the elevator anti-sway device includes a braking assembly 30, the braking assembly includes a braking block 31, the braking block 31 is arranged on one side of the guide rail 2, and the braking surface of the braking block 31 (that is, close to the guide rail 2) An angle is formed between the front side) and the guide surface (that is, the back side away from the guide rail 2), so that the brake block 31 is wedge-shaped (that is, the guide surface of the brake block 31 is an inclined surface); The side surfaces of the guide rail 2 are parallel, and an included angle is formed between the guide surface of the braking block 31 and the side surface of the guide rail 2 .

[0055] The guide block 35 is fixedly connected to the support frame 32 through the elastic body 36; the support frame 32 is fixedly connected to the car; the brake block 31 is connected to the support frame 32 through an elastic element; the actuator 8 is used to maintain the posit...

Abstract

The invention discloses an elevator anti-shaking device. The elevator anti-shaking device comprises a brake assembly arranged on a lift car of an elevator, a lift car door detection unit for detectinga lift car door opening signal, a lift car speed detection unit for detecting the speed of the lift car, a transmission unit for transmitting the detected lift car door opening signal and lift car speed signal to a control unit and the control unit; the control unit receives the lift car door opening signal and the lift car speed signal and controls a brake assembly according to the signals; andthe elevator anti-shaking device relies on electromagnetic operating force to enable the brake assembly to inhibit the lift car from shaking up and down when the operating speed is zero or the door isopened. According to the elevator anti-shaking device, after the elevator stops at a landing and it is judged that the elevator is opened, a brake device acts to clamp a guide rail so as to inhibit the up-and-down shaking of the lift car.

Description

technical field [0001] The invention relates to an elevator device, in particular to an elevator anti-shake device. Background technique [0002] Generally, the elevator car is towed and run by the elastic suspension system. When the car stops at the landing and people or objects enter and exit the car, due to the elasticity of the suspension system, the car will shake up and down in the vertical direction, and this shaking will affect the people. or adversely affect the safety of the material. [0003] Chinese Patent No. 201280074267.4 discloses an anti-sway device for elevator slings, which is an anti-sway device for elevator slings, which is wound from above to an elevator car that is raised and lowered in a hoistway and then is set upward again. The passing body is arranged so that the slings arranged downward from above and the slings arranged upward again intersect above the elevator car, and the penetrating body is arranged at the position where the slings intersect,...
