The invention discloses a metal mine underground electric locomotive braking device. The metal mine underground electric locomotive braking device comprises a lever, an air cylinder, a brake shoe, a first group of special shape levers, a first group of hinge joints, a second group of special shape levers, a second group of hinge joints and couplers, wherein the air cylinder is fixedly installed at the upper end of the lever, the brake shoe is installed on the lower portion of the lever, one end of each special shape lever in the first group of the special shape levers is connected with the brake shoe, the other end of each special shape lever in the first group of the special shape levers is fixedly installed on each hinge joint in the first group of the hinge joints, one end of each special shape lever in the second group of the special shape levers is fixedly installed on each hinge joint in the second group of the hinge joints, the other end of each special shape lever in the second group of the special shape levers is connected with the brake shoe, the bottom of the lever is connected with the bottoms of the second group of the special shape levers through the couplers, the brake shoe comprises a brake shoe block and a brake shoe support, and the brake shoe block is connected with the brake shoe support. The metal mine underground electric locomotive braking device solves the problem that the braking distance of an electric locomotive is long, and eliminates negative effects caused by unidirectional acting force on a wheel and a shaft, generated by the brake shoe during the braking process.
Description
technical field [0001] The invention relates to the field of braking electric locomotives, in particular to a braking device for electric locomotives underground in metal mines. Background technique [0002] The traction equipment of the underground transportation system mostly adopts the electric locomotive with variable frequency speed regulation on DC wire, with 20t electric locomotive and 25t electric locomotive as the mainstream equipment. The mine car is used for ore transportation, and the braking system is composed of hand wheel basic braking, aerodynamic braking and electrical resistance braking. [0003] Aerodynamic braking is mainly used for deceleration braking of electric locomotives, and consists of brake shoes, lever systems, brake cylinders, cross arms and other parts. By compressing air or manually, the brake shoe and the wheel rim are closely attached or separated, so as to realize the braking or release of the system. [0004] The handwheel basic brake i...
