Embodiment Construction

[0016] Refer to the following Figure 1 to Figure 6 A first embodiment of the present invention will be described.

[0017] Figure six It is a structural schematic diagram showing the relationship between the elevator and the speed governor 6. exist Figure six Among them, the elevator car 1 and the counterweight 2 are connected by a main rope 3 wound around a hoist 4 and a pulley 5 . In addition, an endless speed governor rope 7 is wound around a pulley of the speed governor 6 , and a speed governor counterweight pulley 8 is provided at a lower end of the speed governor rope 7 . The frame body 9 of the elevator car 1 and a part of the speed governor rope 7 are clamped by a catch lever 10 of an unshown safety device. The pulley of the speed machine 6, and when it is detected that the specified overspeed occurs due to some reasons, the gear bar 10 is activated through the speed governor rope 7, so that the safety device operates, and if overspeed occurs in the descending d...

Abstract

A speed governor for an elevator, comprising: a speed governor pulley (13) wound with a speed governor rope (7) linked with an elevator car (1) and supported by a shaft; claws (46, 46A) The swing member (18, 18A) moved toward the outer diameter side of the pulley (13) by the centrifugal force generated by the rotation of the pulley (13); is formed by contacting the moving claw (46, 46A) Rotate and release the engaging piece of the switch (22); use its own weight to rotate, and clamp the wedge part (31, 31A) of the governor rope (7) between the opposite clamping piece (37, 37A) ); and a hook that rotates and releases the support of the wedge (31, 31A) by abutting against the claw (46, 46A) that moves further toward the outer diameter side of the pulley (13), wherein, The wedge portion (31, 31A) is urged toward the speed governor rope (7) by the elastic force of the disc spring (43). Therefore, a speed controller for an elevator that can be easily downsized is provided.

Description

technical field [0001] The invention relates to a speed regulator for an elevator. Background technique [0002] As conventional speed controllers for elevators, various speed controllers for elevators have been disclosed. For example, the following patent document 1 discloses a disc-shaped speed governor. The disc-shaped speed governor is configured to push the falling wedge part by the elastic force of the coil spring, and clamp the speed governor rope on it. between the clips. [0003] [Patent Document 1] Unexamined Patent No. 55-26140 ( Figure five Wait) [0004] However, in the speed governor disclosed in the above-mentioned Patent Document 1, there is a problem that, due to the use of a coil spring, the mechanism for clamping the rope of the speed governor becomes larger, thereby reducing the volume of the speed governor for an elevator. big. Contents of the invention [0005] An object of the present invention is to provide a speed controller for an elevator, w...
