A maintenance operation vehicle for anti-offline switch equipment

Abstract

The invention proposes an operation vehicle for maintenance and repair of off-line switch equipment, including a vehicle frame, a longitudinal beam arranged on the vehicle frame, a carrying platform slidingly connected with the longitudinal beam, an operation box arranged on the longitudinal beam, and a The winding drum in the box, the hanging wheel on the beam on the top of the longitudinal beam, the carrying hanging wheel on the carrying platform, and the anti-offline device on the operation box; the anti-offline device includes a hinged horizontal shaft and a hinged horizontal shaft The swing arm connected with the shaft, the off-line wheel on the swing arm, the tension spring on the swing arm, and the anti-off-line pawl on one end of the hinged horizontal axis; When the handle is shaken, the wire rope is loose, and the ratchet pawl is locked under the action of the tension spring, and the handle cannot be shaken in the opposite direction, which avoids the failure of the maintenance vehicle caused by off-line or even the messy winding of the wire rope; Between the winding drums, both positive and negative swings are labor-saving, which reduces the labor intensity of workers.
