Hydraulic disc braking system with electric cylinder and braking method

Abstract

The invention belongs to the field of mine hoisting equipment, and discloses a hydraulic disc braking system with an electric cylinder and a braking method. The system comprises a disc brake device, agas station, an electric cylinder device and a control driving system, wherein the electric cylinder device comprises the electric cylinder and a linear motor device; a gas port of the electric cylinder, a gas outlet of the gas station and a brake gas port of the disc brake device are connected with a main system pipeline, the movable end of the linear motor device is fixedly connected with an electric cylinder piston located in the electric cylinder, and the control driving system is used for driving the linear motor device to move; each brake piston is arranged in a brake cylinder, one endof each connecting bolt is fixedly connected with the corresponding brake piston, the other end of each connecting bolt penetrates through the corresponding brake cylinder and is fixedly connected with a liner plate, each belleville spring set is arranged on the periphery of the corresponding connecting bolt and located in a barrel of the corresponding liner plate, and each brake block is fixedlyarranged on the outer side of the corresponding liner plate and right faces a brake disc. The hydraulic disc braking system is simple in structure, reliable in running and high in efficiency, and canbe widely applied in the field of the mine hoisting equipment.

Description

technical field [0001] The invention belongs to the field of mine hoisting equipment, and in particular relates to an electric cylinder hydraulic disc braking system and a braking method thereof. Background technique [0002] The disc brake system is mainly used in the braking and braking systems of various lifting and transporting machinery and equipment such as belt conveyors, aerial ropeways, and ship lifts, especially in the braking and braking systems of mine hoisting equipment. The disc braking system of mine hoisting equipment in the current technology is completed based on the disc braking system of hydraulic transmission and hydraulic proportional control, and consists of a disc brake device, a hydraulic station, a control system, hydraulic pipelines and connecting cables. Among them, the disc brake device is a brake execution unit that uses components such as disc springs, oil cylinders and brake blocks to apply positive pressure to the brake disc of the lifting eq...
