Embodiment approach 1

[0027] Such as figure 1 , figure 2 with Figure 11 As shown, the anti-fall unit of the elevator disclosed in the present invention includes a bracket 6 firmly connected with the car, a first gear 1, a second gear 4, a guide rail 2, a roller 3, a trigger unit 9, a connecting rod 7, a spring 8. Support shaft 5, nut, washer, cotter pin and sleeve 10, the trigger unit 9 is installed on the bracket 6 by screws, and the roller 3 is freely rotatably installed between the two brackets 6 through the support shaft 5. The first gear 1 is freely rotatably installed between the two brackets 6 by the shaft 5, the guide rail 2 is arranged between the first gear 1 and the roller 3, the first gear 1 meshes with the tooth surface of the guide rail 2, and the roller 3 and the The two smooth surfaces of the guide rail are rolled and matched, and the second gear 4 revolves around the axis of the first gear 1 through the connecting rod 7. At the same time, the second gear 4 rotates freely relati...

Embodiment approach 2

[0036] The second gear 4 located under the bracket 6 in the first embodiment is arranged above the bracket 6, when the trigger end 901 is inserted into the trigger hole 701, the second gear 4 on the connecting rod 7 is kept above the first gear 1 and On the position away from the tooth surface of the guide rail 2, that is, the trigger end 901 keeps the second gear 4 from contacting the tooth surface of the guide rail 2; when the trigger end 901 withdraws from the trigger hole 701, the connecting rod 7 is made The second gear 4 on the top is close to the tooth surface of the guide rail 2, and makes the second gear 4 contact and mesh with the tooth surface of the guide rail 2, which can also realize the anti-falling of the elevator.

Abstract

The invention relates to the field of elevators, in particular to an anti-falling unit for an elevator and discloses an anti-falling unit of an elevator. The anti-falling unit of the elevator comprises a bracket fixedly connected with a lift car and a guide rail arranged along an elevator well. The anti-falling unit of the elevator is characterized by also comprising a first gear, a second gear, a roller wheel, a triggering unit, a connection rod, an elasticity restoring part and a support shaft, wherein the triggering unit is mounted on the bracket; the roller wheel and the first gear are mounted on the bracket through the support shaft in a manner of freely rotating; the guide rail is arranged between the first gear and the roller wheel; the first gear is meshed with the toothed surface of the guide rail; the roller wheel is in rolling fit with the smooth surface of the guide rail; the second gear revolves around the first gear through the connection rod; the second gear and the first gear are meshed with each other; a triggering hole in splicing fit with the triggering end of the triggering unit is formed in the connection rod. When the triggering end is withdrawn from the triggering hole, the second gear is meshed with the guide rail by means of the elastic action of the elasticity restoring part; the freedom degree of the mechanism is 0 at the moment, so that the elevator cannot run up and down, namely the falling prevention of the elevator can be implemented.

Description

technical field [0001] The present invention relates to the field of elevators, in particular but not exclusively to a fall prevention unit for elevators. Background technique [0002] When an accident occurs in the elevator in some cases, the elevator will fall sharply, causing injury to the people who take the elevator. Especially when the rescuers are evacuating the elevator stuck between the floors, the elevator will fall due to an accident, because the falling car and the stationary wall will have a cutting effect on the objects between the two , and some parts of the body of the evacuees are cut off by the falling car. How to avoid the accidental fall of the elevator, thereby reducing personal injuries or casualties has become a problem that people need to solve urgently. Contents of the invention [0003] The object of the present invention is to solve the above problems and provide an elevator anti-fall unit. [0004] To this end, the present invention provides ...
