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

The invention discloses an elevator speed-adjusting set, which comprises the following parts: speed-adjusting pulley (13), which coils the speed-adjusting cord (7) to link elevator vane (1) supported by shaft; swaying components (18, 18A), whose jaw parts (46, 46A) rotate to generate eccentric force through pulley (13) to make pulley (13) move toward external diameter side; chucking piece, which resists to rotate and cancel switch (22) through jaw parts (46, 46A); wedge parts (31, 31A), which utilize self-gravity to rotate and chuck speed-adjusting cord (7) between opposite chucking pieces (37, 37A); hook, which resists jaw parts (46, 46A) to rotate and cancel support of wedge parts (31, 31A); the wedge parts (31, 31A) are pressed towards speed-adjusting cord (7) through elasticity of dish-typed spring (43).

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...
