The middle part of described automobile chassis is also provided with the derrick rotary oil cylinder be connected with fuel tank and Oil pump electrical machinery, and piston rod and the outer derrick front end of described derrick rotary oil cylinder are rotationally connected;
The rear portion of described automobile chassis is also provided with hydraulic tongs secured adjusted device, and described hydraulic tongs secured adjusted device and outer derrick be arranged in parallel;
The front and rear of described automobile chassis is respectively equipped with chassis front leg strut and chassis rear support leg; Described workover rig also comprises for monitoring the descending of suspension hook and the velocity sensor of mentioning speed.
The bottom end of described outer derrick is connected with base rotation, and the other end is removably connected by bolt and base.
Described hydraulic tongs secured adjusted device comprises the telescopic shaft be fixed on automobile chassis and the fixed support rotated around telescopic shaft.
Described chassis front leg strut and chassis rear support leg are respectively hydraulic oil cylinder support legs structure.
The utility model compared with prior art, have the following advantages: it is power, mechanically operated existing conventional workover rig that the utility model replaces with diesel oil, adopt hydraulic-driven, it configures intellectuality, significantly reduce the power of workover rig, that can detect suspension hook in real time removes speed, thus have installed power little, simple to operate, pollution-free, low without canopy rope, noise, take up an area little, safe and reliable, convenient transportation, long service life.
