Problems solved by technology

However, the stroke of the micro switch of the brake is generally greater than 1mm, which will cause a lag problem, that is, after the micro switch is activated, the brake does not operate, but waits until a certain time point after the micro switch is activated. Action occurs, which leads to longer braking time and poor braking stability

Embodiment Construction

[0016] like figure 1 As shown, a traction machine includes a brake 3 and a micro switch 5, and also includes a lever 1, a brake connecting rod 2, a micro switch connecting rod 4 and a fixing member 6, and the brake connecting rod 2 and the brake 3 connected, the micro switch connecting rod 4 is connected with the micro switch 5, the brake connecting rod 2 and the micro switch connecting rod 4 are both fixedly connected to the lever 1, and the lever 1 is fixed on On the fixing part 6, the fixing part 6 is fixedly connected to the traction machine body.

[0017] In order to make the connection position of the brake connecting rod 2 on the lever 1 adjustable, the brake connecting rod 2 and the lever 1 are not welded, but other adjustable connection methods, such as nut connection, and some through holes are set on the lever 1. Let the brake linkage 2 pass through. The brake link 2 can be connected at the midpoint or the lower end of the lever 1 .

Abstract

The invention relates to a tractor. The tractor comprises a brake and a microswitch, and further comprises a lever, a brake connecting rod, a microswitch connecting rod and a fixing piece; the brake connecting rod is connected with the brake; the microswitch connecting rod is connected with the microswitch; the brake connecting rod and the microswitch connecting rod are both fixedly connected to the lever; the lever is fixed on the fixing piece; and the fixing piece is fixedly connected to a tractor body. The tractor has the advantages of simple structure, stable and precise braking work and incapability of generating wrong signals due to the working temperature change.

Description

technical field [0001] The invention relates to a traction machine, in particular to a brake structure of the traction machine. Background technique [0002] The traction machine provides power for the operation of the elevator, and the brake in it acts as a brake on the active shaft. It is an indispensable safety device for the elevator, so that the elevator car in operation can be stopped automatically when the power is cut off. The electromagnet of the brake It is connected in parallel with the motor on the circuit, so when the elevator is running, the electromagnet is attracted to release the brake; when the elevator stops, the electromagnet is released, and the brake shoes hold the brake wheel tightly under the action of the spring to realize the mechanical brake brake. [0003] According to relevant national standards, the braking stroke of the traction machine brake is required to be 0.3-0.5mm, which can ensure short braking time and good braking effect. However, th...
