Abstract

The invention discloses a wheel dragging prevention device and method for an electric locomotive. The wheel dragging prevention device and method for the electric locomotive are suitable for monitoring the wheel dragging of the electric locomotive, and the problems that the locomotive moves forcedly when braking wheels of the electric locomotives are not released and under the condition of no warning, thus, the braking wheels are dragged for a long time and then are damaged finally, and the running safety of the locomotive is affected are solved. The device comprises a speed sensor, an alarm unit and a main machine; the speed sensor is arranged at a wheel, the main machine is arranged in an electric cabinet, the alarm unit is arranged in a control room, and the speed sensor, the main machine and the alarm unit are electrically connected. A main control board of the wheel dragging prevention device calculates, analyzes and diagnoses signals input by the speed sensor; and when wheel dragging is discovered in fault diagnosis of a main board, the alarm unit in the control room sends an alarm prompt to remind workers of fault treatment.

Description

technical field [0001] An anti-tug device and method for an electric locomotive, which is suitable for monitoring the tug phenomenon of an electric locomotive. Background technique [0002] When the brake wheel is not released, the phenomenon that the brake wheel is dragged and slid by the driven wheel is called tug wheel. The braking wheel of the electric locomotive was not relieved, and the vehicle was forcibly driven without warning, resulting in the brake wheel being damaged after long-term tug operation, which affected the safety of the locomotive. Contents of the invention [0003] The invention provides a solution to solve the problem that the brake wheels of electric locomotives are not relieved and forced to drive without warning, resulting in the brake wheels being damaged after long-term tug operation and improving the safety of locomotive operation. [0004] Technical solution: An anti-tug device for an electric locomotive includes a speed sensor, an alarm uni...
