As preferred version of the present invention, described vehicle frame also comprises the hydraulic control room controlling the hydraulic mechanism be arranged on described vehicle frame.
As preferred version of the present invention, described vehicle frame is also provided with the hoist engine that the described injection head bearing of traction slides on described derrick.
As preferred version of the present invention, the lower end of described injection head connects preventer combination.
As preferred version of the present invention, the setting operation room, front end of described vehicle frame, the bottom of described operating room is provided with and drives its braced structures hoisted.
As preferred version of the present invention, it is characterized in that, described vehicle frame is semitrailer.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows:
1, the present invention can ensure that injection head remains the inconvenience being connected to avoid poling to cause under operation with travel position with continuous-tube.
2, compared with loop wheel machine, this derrick form supporting capacity is strong, and well-location adjustment is convenient.
3, the structure of semitrailer is adopted can to reduce the cost of transport vehicle.
