An anti-falling device for a building-type machine room-less elevator and its application method

Abstract

The invention discloses an anti-falling device for a building-type machine room-less elevator and a use method thereof, which comprises a car and an elevator shaft body, and the car is arranged in the elevator shaft body. When the traction force of this device disappears, the second spring, the rotating rod and the guide wheel are used together, so that the hinge rod drives the splint to move upwards and fits closely with the side wall of the elevator shaft body, and an anti-skid layer is set on one side of the splint. This effectively increases the frictional resistance between the splint and the elevator shaft body, so that the car can be effectively fixed in the elevator shaft body, avoiding serious injury to the people inside the car due to landing, and even if the inside of the car is fully loaded and heavy, the setting of the splint can also Effectively reduce the descending speed of the car, and under the setting of the first rack, pinion and second rack, when the car slowly falls and touches the ground, the setting of multiple first springs can effectively The buffer function provides double protection for the internal personnel and effectively ensures that the personnel land safely.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a fall prevention device for a construction machine room-less elevator and a method for using it. Background technique [0002] As a common tool for vertical lifting on construction sites, machine room-less elevators have the advantages of high transmission height, high acceleration, and rapid lifting. They are also widely used in civil and industrial fields, such as large shopping malls, teaching buildings, hospitals, buildings, mines, Mountains etc. The complex and changeable application environment also puts forward higher requirements for the various safety structures of machine room-less elevators. However, in actual use, problems such as failure of the safety device of the elevator, insufficient traction, and failure of the speed limiter often occur, resulting in an elevator falling accident, causing heavy property damage and casualties. Can not guarantee the safety ...

AI Technical Summary

Problems solved by technology

However, in actual use, problems such as failure of the safety device of the elevator, insufficient traction, and failure of the speed limiter often occur, resulting in an elevator falling accident, causing heavy property damage and casualties. It cannot guarantee the safety of passengers well, and it will still cause arm fractures or even casualties, and it does not solve the safety problem well.
