[0013] Example

[0014] A brake shoe brake wear protection device, such as figure 1 As shown, the brake shoe includes a brake shoe and a brake disc 1. The brake shoe includes two brake shoe bodies 4, the brake disc 1 is located in the gap between the two brake shoe bodies 4, and an electric contact rod 3 is provided on the two brake shoe bodies 4, Contact pin electrodes 2 are provided on the electric contact poles 3, and there is a gap between the contact pin electrodes 2 and the brake disc 1. The contact pin electrodes 2 are all connected to the buzzer 9, the alarm 8 and the hoist controller 6 through wires 5. The gap between the two brake shoe bodies 4 is less than 2 mm. The contact pin electrodes 2 are all connected to the LED lights 7 through wires 5.

[0015] The brake disc 1 of the mine hoist is braked by the brake shoe. The two brake shoe bodies 4 are equipped with electric contact rods 3, and the contact needle electrodes 2 are arranged on the electric contact rods 3, and...

Abstract

The invention belongs to the field of shoe braking, and particularly relates to a shoe braking abrasion protection device. The shoe braking abrasion protection device comprises a shoe ad a braking disc; the shoe comprises two shoe bodies; the braking disc is located in a clearance between the two shoe bodies; each shoe body is provided with an electricity contact rod; each electricity contact rodis provided with a contact pin electrode; a clearance is preserved between each contact pin electrode and the braking disc; each contact pin electrode is connected with a buzzer, an alarming device and a lifting controller through a conductor; the clearance between the two shoe bodies is smaller than 2 mm; each contact pin electrode is connected with an LED lamp through a conductor; when the shoeis abraded to a safety thickness, the shoe braking abrasion protection device can inducts the condition sensitively, so that a lifter stops operation; and a repairer is reminded to repair, so that accidents are avoided, and the shoe braking abrasion protection device is high in reliability and safety.

Description

technical field [0001] The invention belongs to the field of brake shoe braking, and in particular relates to a brake shoe brake wear protection device. Background technique [0002] The brake device is an important part of the mine hoist. The brake shoe is a common mine hoist brake device. The brake shoe is an important part to ensure the safety of people. Its working braking and safety braking performance should comply with safety regulations. The brake shoe is used for a long time and is easy to wear, which affects the braking performance and is very dangerous. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a brake shoe brake wear protection device, which can sense sensitively when the brake shoe is worn to a safe thickness, stop the hoist, and remind maintenance personnel to Maintenance, so as to avoid accidents, high reliability and safety. [0004] The brake shoe braking wear prote...
