FLOATING TYPE DISC BRAKE FOR KILOMETER-DEEP WELL ELEVATOR

摘要

A floating type disc brake for a kilometer-deep well elevator. The floating type disc brake comprises a brake disc (3), a main disc body, an auxiliary disc body and a floating type structure. The main disc body comprises a mechanical brake unit and a state monitoring unit. The mechanical brake unit comprises a brake shoe B (6), a liner plate B (5), a pressing sleeve (4), a pressing plate (19), a screw (22), a brake cylinder barrel (10), a brake piston (21), a T-shaped piston (15), a disc spring assembly (11) and a cylinder cover (12). The state monitoring unit comprises a pressure sensor (17), a disc spring base sensor (13) and an eddy current sensor (30). The auxiliary disc body comprises a brake shoe A (2) and a liner plate A (1). The floating type structure comprises a sliding pin shaft (24), a spring (27) and a support (26). The brake can dynamically monitor a brake positive pressure and a gap between the brake shoes (6, 2) and the brake disc (3), the abrasion loss of the brake shoes (6, 2), and the fatigue break state of the disc spring assembly (11). Meanwhile, real-time automatic compensation for abrasion of the brake shoes (6, 2) and automatic alignment of the brake disc (3) can be achieved.
