Construction elevator security auxiliary device

Abstract

The invention relates to the field of construction elevator manufacturing, in particular to a construction elevator security auxiliary device which comprises a vertical track, an elevator body, a speed reducer motor and an elevator top cover, wherein an accommodation cavity is formed in the bottom of the elevator body; the speed reducer motor is arranged inside the accommodation cavity; the speed reducer motor is meshed with the rack of the vertical track through a power gear; the around part of the elevator top cover is connected with the elevator body through buckles; the elevator top cover is provided with coilers; safety belts are fixedly connected below the coilers through ropes; a support suspending arm is fixedly connected above the elevator top cover; the suspending arm is connected with the vertical track through a brake gear; a band-type brake is arranged on the brake gear; the triggering rope of the band-type brake is connected with the safety belts. The construction elevator security auxiliary device has the beneficial effects that when an elevator drops down, the large-mass construction elevator body can be discarded, the brake effectiveness of the elevator top cover is ensured, and constructors can be out of danger; the scheme is simple and reliable and has the popularization significance.

Description

technical field [0001] The invention belongs to the field of construction elevator manufacturing, in particular to a safety auxiliary device for construction elevators. Background technique [0002] Construction elevator is a kind of construction machinery that transports construction personnel, equipment or materials through the transmission device to make the cage move vertically or obliquely. It is mainly used for interior and exterior decoration of high-rise buildings, bridges, chimneys and other buildings. Compared with other lifting mechanisms, the construction hoist does not need another machine room or shaft, and has a stable structure, safety and reliability, and has significant advantages in reducing the labor intensity of construction personnel and speeding up work efficiency. [0003] In recent years, the use of elevators in high-rise buildings has become more and more common. However, due to the gap between product safety performance and general manned elevators...

AI Technical Summary

Problems solved by technology

[0003] In recent years, the use of elevators in high-rise buildings has become more and more common. However, due to the gap between product safety performance and general manned elevators, the working environment at the construction site is poor, the safety management of the construction unit is not in place, and the safety supervision ability of the supervision unit is insufficient. As a result, there are often major safety hazards in the equipment

As for the construction elevator, it is the only vertical transportation equipment that can carry people on the construction site. Improper safety management may cause the ladder cage to fall, causing mass death and mass injury accidents

The anti-fall device is an important part of the construction elevator. Due to various reasons, the anti-fall device often fails to work, resulting in safety accidents. At present, there are no other anti-fall safety measures on the construction elevator.

Once an accident occurs, the people in the elevator completely lose the ability to save themselves
