[0002] The workover rig is a kind of oilfield operation machine. It realizes its own walking and workover functions through the power switching device. When the workover rig is in the walking state, the engine power is transmitted to the front axle of the chassis through the transmission, transfer case and drive shaft. And the rear axle, before performing workover operations such as drilling and oil fishing, the operator needs to manipulate the power switching device to switch the engine power to the workover rig working device. When switching power, the operator needs to climb the frame of the workover rig On the narrow fixed table, it is very inconvenient to operate, and there are potential safety hazards

The invention discloses a well repair machine power switching device and relates to the field of oil field operation auxiliary machinery, in particular to the well repair machine power switching device. The well repair machine power switching device comprises a support seat fixed to a crossbeam in a vehicle frame, and a support fixed to a longitudinal beam on the left of the vehicle frame. A second transmission shaft is rotationally connected to the support seat and is connected with a first transmission shaft through a coupling. The first transmission shaft is rotationally connected with thesupport. A handle is connected to the tail end of the support. Two swing arms are arranged on the second transmission shaft and are the front swing arm and the rear swing arm correspondingly. The wellrepair machine power switching device is simple in structure, an operator can conduct power switching operation on the ground, and combination and separation movements are stable and reliable duringpower switching.
