Embodiment Construction

[0009] Below in conjunction with Fig. 1, describe in detail the concrete work situation that the present invention proposes, figure 1 In the elevator main body 10, the machine room 1, the main steel cable 3, the car guide rail 4, the car 5 and the car buffer 8 are fixedly installed, and the car buffer 8 is installed at the bottom 9 of the hoistway 7, and then in the machine room A speed control device 2 is installed in 1, and a backstop 6 is installed on the car guide rail 4 under the car 5, and the backstop 6 is electrically connected with the speed control device 2.

[0010] By installing a backstop 6 on the car guide rail 4 under the car 5, when the car 5 is running at a normal speed, the suppressor 6 slides up and down with the car 5 and does not work; when the main steel cable 3 breaks or other failures occur When the falling speed of the car 5 exceeds the speed set by the speed control device 2, the backstop 6 is activated, and the backstop 6 is firmly fixed on the guide...

Abstract

The invention relates to a device for preventing elevator falling. A speed control device is mounted in a machine room. A backstop electrically connected with the speed control device is mounted on the guiderail below an elevator car. When the elevator car moves at normal speed, the backstop slides up and down along the elevator car and does not work. When a main steel cable breaks or other faults occurs and the falling speed of the elevator car exceeds the set speed of the speed control device, the backstop starts and firmly fixes on the guiderail to prevent the elevator car from falling, the elevator car can be effectively and firmly fixed on the guiderail, and the elevator car is prevented from directly falling to the shaft bottom and causing irredeemable loss.

Description

technical field [0001] The invention is an elevator fall prevention device, which belongs to the field of electronic technology. Background technique [0002] The current elevator is not equipped with a backstop. When the main steel cable breaks, the car will directly slide into the bottom of the well, causing irreparable loss of life or property. Contents of the invention [0003] The object of the present invention is to provide an elevator fall prevention device, and the purpose of fixing the fast sliding of the car is achieved by installing a backstop on the guide rail of the car. [0004] Its purpose is achieved in this way, the elevator fall prevention device is composed of machine room, speed control device, main steel cable, car guide rail, car, backstop, shaft, car buffer, shaft bottom, elevator main body; The machine room, the main steel cable, the car guide rail, the car, and the car buffer are fixedly installed on the main body, and the car buffer is installed...
