Falling protection system for building construction elevators

Abstract

A falling protection system for building construction elevators comprises a descent control device, a slow descent rope, and one or a plurality of rope catchers. The rope catches are disposed on a cage of a construction elevator. The slow descent rope extends out of the descent control device, extends to be above the cage, extends from top to bottom, and is then fixedly connected to an appropriate position below the cage. The slow descent rope can be fastened through the rope catchers to allow for descent at the safety speed under the action of the descent control device.

Description

technical field [0001] The invention belongs to an anti-falling technology for a construction elevator. Background technique [0002] At present, the construction safety problems of the building under construction frequently occur. The main project of the building under construction must be combined with the construction elevator during the construction process. It is used for vertical transportation during construction. It is a dual-purpose elevator that carries people and materials. Because it is attached to the outside of the main body of the building, it is also called an external elevator. In recent years, the use of elevators in high-rise building construction has become more and more common. However, due to the certain gap between product safety performance and general passenger elevators, the working environment at the construction site is poor, the safety management of the construction unit is not in place, and the supervision unit has the ability to supervise safet...

AI Technical Summary

Problems solved by technology

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 passenger 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 supervisory unit Insufficient, resulting in equipment often have major safety hazards

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 (also known as the car) to fall, resulting in mass death and mass injury accidents.

The reasons for the falling of the elevator cage of the construction elevator include: 1. After the guide rail frame was raised, the stopper of the upper limit travel switch and the upper stopper of the limit switch were not installed in time. The connecting bolts of the standard section of the guide rail frame above the wall point are damaged, and the guide rail frame is broken and then falls from a high place; 2. The anti-fall device fails. The anti-drop safety device is an important part of the construction elevator, and it must be relied on to eliminate the ladder cage fall accident However, 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 construction elevators.
