An electric cylinder hydraulic disc braking system and braking method

Abstract

The invention belongs to the field of mine hoisting equipment, and discloses an electric cylinder hydraulic disc braking system and a braking method thereof. The system includes a disc brake device, a gas station, an electric cylinder device and a control drive system, and the electric cylinder device includes an electric cylinder. and linear motor device; the oil port of the electric cylinder, the oil outlet of the gas station and the brake oil port of the disc brake device are all connected to the main pipeline of the system, and the movable end of the linear motor device is fixedly connected with the electric cylinder piston located inside the electric cylinder , the control drive system is used to drive the movement of the linear motor device; the brake piston is set in the brake cylinder, one end of the connecting bolt is fixedly connected with the brake piston, and the other end is fixedly connected with the liner through the brake cylinder, and the disc spring group is set in The outer periphery of the connecting bolt is located in the barrel of the liner, and the brake block is fixedly arranged on the outer side of the liner facing the brake disc. The invention has the advantages of simple structure, reliable operation and high efficiency, and can be widely used in the field of 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...
