Embodiment Construction

[0012] The power of the elevator is provided by the motor. Under the control of the controller, the motor drives the reducer, and then drives the gear to realize the corresponding lifting movement of the elevator car. The speed limiter used on the elevator according to the present invention reduces the rotating speed of the friction shaft 4 through the interaction between the friction plate 33 in the retarding unit and the friction shaft 4, thereby reducing the speed of the elevator running power shaft 1 (that is, the output shaft of the speed reducer). ) speed, so as to achieve speed limit protection.

[0013] Such as figure 1 , 2 As shown, the speed governor for an elevator according to the present invention includes a runner 3, a friction shaft 4 and a blocking unit. The runner 3 is fixedly sleeved on the friction shaft 4, and the runner 3 is symmetrically arranged along There are two radial grooves 34 in the radial direction, and there are two blocking units, including ...

Abstract

The invention provides a speed governor for an elevator, which includes a running wheel, a friction shaft and a blocking unit. The running wheel is fixedly sleeved on the friction shaft. There are two blocking units, including a centrifugal block, a connecting rope and a friction plate, and the centrifugal block and the friction plate are connected by a connecting rope; the connecting rope in the blocking unit is worn on the friction shaft, and the centrifugal block The sliding is placed in the radial groove; the friction plate is an arc-shaped sheet structure; the connecting rope is an elastic rope. The speed limiter used in the elevator provided by the present invention is designed with a mechanical structure, the structure is simple, and the cost is reduced; through the interaction between the friction plate in the block unit and the friction shaft, the rotational speed of the friction shaft is reduced, thereby reducing the speed of the friction shaft. The speed of the elevator running power shaft, so as to realize the function of speed limit protection.

Description

technical field [0001] The invention relates to a speed governor for an elevator. Background technique [0002] In modern society, elevators are widely used in people's daily life. The importance of the overspeed protection of the elevator is self-evident. In the prior art, the overspeed protection is mainly realized through the speed limiter, but the existing speed limiter has a complicated structure, a large volume, and is expensive, which causes the elevator follow-up One of the main reasons for high maintenance costs. In reality, reports of various elevator accidents caused by untimely elevator follow-up maintenance due to cost issues have been repeatedly disclosed. Contents of the invention [0003] Based on the above reasons, the present invention provides a speed governor for an elevator, which includes a running wheel, a friction shaft and a blocking unit. There are two radial grooves, and there are two blocking units, including a centrifugal block, a connecting...
