Description

Technical Field

[0001] The utility model relates to the technical field of disc brakes, in particular to a disc brake utilizing PLC and a photoelectric slow reflection switch. Background Art

[0002] In the safe production of coal mining, the performance and maintenance of equipment are crucial. Especially for key equipment such as mine hoists, the disc brakes they are equipped with must meet the strict safety requirements of the "Coal Mine Safety Regulations". According to Article 426 of the regulations, the gap between the disc brake block and the disc shall not exceed 2mm, which is a key parameter to ensure the braking performance and safe operation of the hoisting system.

[0003] However, existing disc brakes, such as a transport winch with a disc brake disclosed in the invention patent with authorization announcement number CN110329934B and a water-cooled disc brake for a coal mine down-carrying belt conveyor disclosed in the utility model patent with publication number CN204777218U, can achieve braking, but it is inconvenient to monitor the distance between the brake block and the brake disc, resulting in poor safety of the disc brake. Therefore, a disc brake using PLC and photoelectric slow reflection switch is urgently needed to improve the above problems. Utility Model Content

When the gap between the gate block and the gate disc exceeds the standard, or when the gate block is worn, the photoelectric slow reflection switch loses the obstruction of the gate block below, and an alarm is issued through the alarm mechanism to remind the staff to inspect the gate block and the gate disc, thereby improving the practicality of the equipment.
