Description

Technical Field

[0001] The utility model relates to the field of brake devices, in particular to a wheel brake device for a coking electric locomotive. Background Art

[0002] The electric locomotive is equipped with both electrical and mechanical braking systems. During operation, the electric brake is mainly used to achieve satisfactory results. The electric brake is controlled by operating the hand wheel of the driver controller. The mechanical brake of the electric locomotive is composed of brake shoes, levers, brake screws and nuts, hand wheels and balance arms. It brakes four wheels at the same time through four unidirectional brake shoes. When braking, the driver only needs to operate the brake handwheel in the driver's cab. The handwheel rotates clockwise for braking and reverses for relief. A Chinese patent discloses a hydraulic disc brake device for mining electric locomotives (authorization announcement number CN 202669840 U). The patented technology can reduce the labor intensity of the driver operating the locomotive, has good heat dissipation, and does not cause brake failure when the brakes need to be stepped on continuously, ensuring safety. The disc brake system has a fast response speed and can perform high-frequency braking actions. The braking force is relatively even, and the driver will not panic due to uncontrollable braking force. Because the drainage of the brake disc is better, the situation of poor braking caused by water or mud can be reduced. The disc brake has a simple structure and is relatively cheap to maintain. However, the disc brake described in the design is not equipped with a return spring, which may cause brake failure, seriously threatening driving safety. Therefore, a person skilled in the art provides a wheel brake device for a coking electric locomotive to solve the problems raised in the above background technology. Utility Model Content
