Abstract
The utility model discloses a coal mining machine electric control box fixation damping device which is used for fixing electric control boxes and comprises a casing body. A number of grooves are arranged at the bottom of the inner wall of the casing body. The device further comprises a guide damping component which is correspondingly arranged in each groove and a locking component which is fixed between the top of each electric control box and the inner wall of the casing body, wherein each electric control box is arranged on each guide damping component. Each guide damping component comprises a rubber damping pad which is arranged in each groove and a guide steel plate which is arranged on each rubber damping pad. The device can damp vibration produced in the use process of the electric control boxes underground, improves the service lives of internal components of the electric control boxes, and reduces the failure rate of a coal mining machine.
