Problems solved by technology

Brake opening oil pressure is the oil pressure value at the moment when the brake shoe just leaves the brake disc. Similarly, the brake oil pressure is the oil pressure value at the moment when the brake shoe just touches the brake disc. Due to the response speed of the oil pressure and brake clearance sensor measurement The measured oil pressure curve and brake clearance change curve are irregular, so there is a large difference between the oil pressure of opening and closing the brake measured by capturing and measuring with feeler gauge and paper in the technical measurement, and the accuracy is difficult to achieve Requirements, this method is called an indirect measurement method, and because the oil pressure is residual pressure or zero in the braking state, it is impossible to directly measure the positive brake pressure through the oil pressure

Abstract

This invention is disk brake which monitors braking positive pressure under braking state. It includes braking disk, brake shoe, lining board, butterfly spring, joining bolt, brake seat, hydraulic cylinder, adjusting screw stem and piston. The superior part of lining board has a big groove, which bottom has a blind hole. The joining bolt rod has two bosses. The bottom boss is welded in blind hole at bottom of lining board. The middle boss is arranged with sleeve, which bears butterfly spring. There is sensor between joining bolt and sleeve. Nut component is set above joining bolt. This invention can measure positive pressure directly under braking state. Positive pressure data multiplies friction coefficient and brake radius to get brake moment, in order to monitor brake moment and check total brake moment is whether or not bigger than 3 times maximal static moment. This invention has widely practicability.

Description

technical field [0001] The invention relates to a disc brake for monitoring the braking positive pressure in the braking state, and is especially suitable for directly measuring the positive pressure in the braking state of a mine hoist, and also suitable for directly measuring the positive pressure in a belt conveyor in the braking state. Background technique [0002] The disc brake of the mine hoist generates a positive braking pressure by a butterfly spring, and the brake is released by hydraulic pressure. The generally used hoist disc brakes of mine hoists at home and abroad are all produced by butterfly springs and released by oil pressure. When the brake is braking, the oil pressure is zero, relying on the pre-compression force of the disc spring, the brake shoe, liner, piston and connecting screw are pressed against the brake disc together, as if the brake disc is clamped, to achieve braking. When the brake is released, the pressure oil is passed into the piston cham...
