Elevator falling preventive device applicable to old building transformation

Abstract

The invention discloses an elevator falling preventive device applicable to old building transformation, and relates to the technical field of elevators. The elevator falling preventive device comprises an elevator car body. The elevator car body is arranged in a shaft; a speed sensor and a controller are fixed to a surface of the elevator car body; a clamping mechanism is arranged on the upper portion of the elevator car body; a speed reduction mechanism is arranged on the lower portion of the elevator car body; the clamping mechanism comprises limit components, a first motor and clamping rods; two ends of each limit component are fixed to the inner wall of the upper portion of the shaft and the inner wall of the lower portion of the shaft; the first motor is arranged on the upper surfaceof the elevator car body; the clamping rods are slidably arranged on the upper portion of the elevator car body; the speed reduction mechanism comprises speed reduction plates, a second motor and retardance components; the speed reduction plates are fixed onto the inner wall of the shaft; the second motor is arranged on the lower surface of the elevator car body; the retardance components are slidably arranged on the lower portion of the elevator car body. The elevator falling preventive device has the advantages that the clamping mechanism and the speed reduction mechanism are matched with each other, and accordingly the operating safety factors of elevators in old buildings can be increased.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to an elevator anti-falling device suitable for renovation of old buildings. Background technique [0002] An elevator is a vertical elevator powered by an electric motor, which is used in multi-storey buildings to take people or carry goods. At present, the elevators in old buildings are generally installed for a long time, resulting in a greatly reduced safety factor; moreover, most of the elevators in old buildings are installed without considering the installation of anti-fall equipment for elevators, which threatens the lives of passengers even more; Existing anti-falling equipment for elevators is generally all used in conjunction with modern elevators, and the installation parts and installation standards between the anti-falling equipment for elevators and the elevator of old buildings cannot be used in conjunction at all. Therefore, need a kind of elevator fa...
