Anti-derailing safety protection device used for construction lift

Abstract

The invention discloses an anti-derailing safety protection device used for a construction lift. The anti-derailing safety protection device structurally comprises a lifting suspended table, a loadingbase plate, a protective guard, an electric motor, a power case, a balance rail limiting device, a guide-rail-type lifting beam, a strengthening beam, a fixing plate, a lifting driving mechanism, a steel-made chain, a top transverse beam and a fixed pulley. The loading base plate is arranged at the front edge of the lifting suspended table and connected with the lifting suspended table through electrowelding, and the protective guard is arranged above the left edge, the right edge and the rear edge of the lifting suspended table and connected with the lifting suspended table in a perpendicular-shaped mode through electrowelding. According to the anti-derailing safety protection device used for the construction lift, the balance rail limiting device is arranged, provided magnetic rollers of the anti-derailing safety protection device can be limited in a sliding rail to freely slide and cannot fall off due to magnetic force, and thus the effective anti-derailing effect is achieved; andthe anti-derailing safety protection device is provided with a balance force-bearing rod so that fixing of the suspended table can be reinforced, meanwhile the maximum bearable force of the suspendedtable is increased, and the practicability and safety of the construction lift are effectively improved.

Description

Technical field [0001] The invention is an anti-derailment safety protection device for a construction elevator, which belongs to the field of elevators. Background technique [0002] Lifts, lifting working platforms are a kind of multifunctional lifting mechanical equipment, which can be divided into fixed type and mobile type, rail type, crank type, scissor type, chain type, loading and unloading platform, etc. Lifts are usually used for rescue and decoration. [0003] The prior art discloses the application number CN201520954529.7, a derailment prevention safety protection device for a construction hoist. The invention discloses a derailment prevention safety protection device for a construction elevator. The elevator includes a main beam of a hanging cage and a main beam of a driving frame arranged in an up and down direction. The safety protection device includes a main beam and a main beam installed on the driving frame. There are several safety shaft mechanisms on the fron...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an anti-derailment safety protection device for construction elevators, to solve the poor anti-derailment effect of the prior art, or the large energy loss caused by the frictional force of the anti-derailment, Reduce the lifting speed of the construction hoist, affect its working efficiency, and its balance performance is poor, and the maximum force that the suspension platform can bear is small.
