Embodiment Construction

[0016] The following are specific embodiments of the present invention, and in conjunction with the accompanying drawings, further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] A safety anti-fall elevator, such as figure 1 As shown, it includes an elevator shaft 10, a guide rail 11 disposed on the elevator shaft 10, a traction machine 20, and a car 30 connected to the traction machine 20 through a traction rope 21. The two sides of the car 30 are slidingly arranged on the guide rail 11, In the traditional elevator structure, under the traction action of the traction machine 20 and the guidance and stability maintenance action of the guide rail 30, the traction rope 21 drives the car 30 to move up or down. In the present invention, an anti-falling device is also included. The anti-falling device includes a motor 41 and a screw 42 that is arranged on the output shaft of the motor 41 and is parall...

Abstract

The invention relates to the technical field of elevators, in particular to a safe fall prevention elevator comprising an elevator shaft, a guide rail, a tractor and a car. The guide rail and the tractor are arranged in the elevator shaft. The car is connected with the tractor through a traction rope. The two side edges of the car are slidably arranged on the guide rail. The safe fall prevention elevator further comprises a fall prevention device. The fall prevention device comprises a motor and a screw, and the screw is arranged on an output shaft of the motor and is parallel to the directionof the guide rail. The car comprises a bearing cavity and solid parts, and the solid parts are arranged in the positions, close to the two ends of the guide rail, of the bearing cavity correspondingly. The solid parts are provided with inner threaded holes in threaded connection with the screw. The elevator is pulled through the motor and the tractor, when the tractor fails, the car is preventedfrom moving too fast through the thread limiting characteristic, and thus the purpose of safe fall prevention is achieved.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a safe anti-fall elevator. Background technique [0002] As a common vertical lifting tool, traction elevators are widely used in large commercial buildings or office buildings. They have the advantages of high transmission height, high acceleration, and rapid lifting. They are widely used in civil and industrial fields, such as large shopping malls, teaching buildings, and hospitals. and other buildings, mines, mountains, etc. The complex and changeable application environment also puts forward higher requirements for the various safety structures of the traction elevator. However, in actual use, problems such as electrical safety device failure, insufficient traction force, and speed limiter failure often occur, and frequent ladder accidents occur. Therefore, a safety anti-fall elevator is needed. Contents of the invention [0003] The present invention aims to solve the ...
