TE032 brake shoe wear protection switch for winches

Our company specializes in the production of mining brake shoe wear switches. This utility model provides a low-potential stylus type brake shoe wear switch device, which is composed of stylus electrodes, intermediate relays, rectifier bridges, control transformers, time relays, indicator lights, and buzzers. The output current of the control transformer is rectified by the rectifier bridge and the output is direct current. The DC negative pole is grounded and the positive pole is connected to the contact pin electrode. There is a gap between the contact pin electrode and the brake disc. The alarm relay controls the time relay and the audible and visual alarm circuit. The opening and closing indicator light and Buzzers connected in parallel have the characteristics of high reliability and safety, which can prevent electric shock and reduce personal injury.

>Brake shoe wear switch is a mechanical switch designed specifically for detecting and controlling the brake shoe gap of the elevator disc brake. The dry contact output mode can detect the brake shoe gap (using normally closed contacts) and monitor the disc spring fatigue damage (using normally open contacts). After being applied to the elevator disc brake, it can be directly connected to the

> for monitoring. When there is a safety problem, it can automatically sound and light alarm. In addition, it can also be connected to the electronic control. The system can automatically power off the electronic control when encountering safety issues. Such a setting can meet the requirements of the "Coal Mine Safety Regulations" regarding the control of brake shoe clearance.

> Disc spring fatigue detection adjustment setting:
> Disc spring fatigue detection can be carried out using the normally open contact state of the travel switch. . Keep the brake in the open state, push the contact push rod of the brake shoe wear switch against the baffle until you hear a clicking sound, and then withdraw the wear switch backward
>Re-fix it. If the disc spring is fatigued and the switch is opened, The amount of gap behind the gate is greater than usual
>After the above, it is considered a fault. At this time, the normally open contact of the switch closes and sends a signal to alarm.

Brake shoe wear switch model for mine hoist disc brake:.

The outer casing is made of aluminum with one pair of normally open and one pair of normally closed voltage contacts. This part is installed on the side of the disc brake to detect the wear degree of the brake shoe.

The winch braking device is an important part of the mining winch. The correctness of brake shoe wear protection is directly related to the operational safety of the winch. The "Coal Mine Safety Regulations" require that when the wear gap of the brake shoe exceeds the specified value, it can automatically alarm or automatically cut off the power.
The brake shoe wear switch produced by our company is specially designed to detect and control the brake shoe gap of the elevator disc brake. It is a mechanical switch dry contact output form that can complete the detection of the brake shoe gap (usually used Monitoring of fatigue breakage of disc springs (closed contacts) and disc spring fatigue breakage (using normally open contacts). After being applied to the elevator disc brake, it can be directly connected to the brake shoe wear alarm device for monitoring. It can automatically issue audible and visual alarms when safety problems are encountered. In addition, it can also be connected to the electronic control system to control the electronic control when safety problems are encountered. Carry out automatic power-off processing. Such a setting can meet the requirements of the "Coal Mine Safety Regulations" regarding the control of brake shoe clearance.
