Construction lift for building under construction

Abstract

The invention discloses a construction lift for a building under construction. The construction lift comprises a guide track bracket, a cage and a motor. The construction lift is equipped with an anti-dropping system which comprises a rope grabbing device and a safety rope. The rope grabbing device is arranged on the cage of the construction lift; one end of the safety rope is connected at a setting position above the cage; the safety rope extends from top to bottom to run through the rope grabbing device arranged on the cage and is connected and fixed at a proper position below the cage; the rope grabbing device is sleeved at the outer side of the safety rope and can lift and descend freely on the guiding track bracket of the construction lift; and when the rope grabbing device is activated, the cage grabs and fixes the safety rope through the rope grabbing device.

Description

technical field [0001] The invention belongs to the field of construction elevators. Background technique [0002] Construction elevator refers to the elevator used for vertical transportation in building construction to carry people and materials. It is also called external elevator because it is often attached to the outside of the building. 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 security risks 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, ...

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 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 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 breaks and falls from a high place; 2. The fall arrester fails and fails

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.
