Embodiment approach 1

[0028] Such as figure 1 , figure 2 and Figure 11 As shown, the anti-fall unit 0 of an 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, Spring 8, support shaft 5, nut, washer, cotter pin and sleeve 10, trigger unit 9 is installed on the support 6 by screw, roller 3 is installed freely rotatably between two support 6 by support shaft 5, through The support shaft 5 installs the first gear 1 freely rotatably between the two brackets 6, 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 Cooperate with the two smooth surfaces of the guide rail, the second gear 4 revolves around the axis of the first gear 1 through the connecting rod 7, and at the same time, the second gear 4 rotates freely relative to the connecting rod 7, and the ...

Embodiment approach 2

[0038] 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 and in particular relates to an anti-falling elevator. The invention discloses the anti-falling elevator. The anti-falling elevator mainly comprises a bracket fixedly connected with a lift car, a guide rail arranged along an elevator well and an anti-falling unit. The anti-falling elevator is characterized in that the anti-falling unit comprises a first gear, a second gear, a roller, a triggering unit, a connection rod, an elastic restoring part and a support shaft; the triggering unit is mounted on the bracket; the roller and the first gear are freely and rotationally mounted on the bracket by virtue of the support shaft; the guide rail is arranged between the first gear and the roller; the first gear is meshed with the toothed surface of the guide rail; the roller is in rolling fit with the smooth surface of the guide rail; the second gear rotates around the first gear and is meshed with the first gear by virtue of the connection rod; the connection rod is provided with a triggering hole in insertion fit with a triggering end of the triggering unit. When the triggering end is withdrawn from the triggering hole, the second gear is meshed with the guide rail by means of the elastic force of the elastic restoring part, the freedom degree of the mechanism at the moment is 0 and the elevator is incapable of running up and down, so that the falling of the elevator can be prevented.

Description

technical field [0001] The present invention relates to the field of elevators, in particular but not exclusively to an anti-fall elevator. 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 anti-fall elevator. [0004] For this reason, the present invention provides a kind of anti-f...
