Continuous oil pipe semitrailer

The utility model relates to a continuous oil pipe semitrailer. The continuous oil pipe semitrailer consists of a semitrailer, a control chamber, a power unit, an injection head, a continuous oil pipe expansion cylinder and a continuous oil pipe wound on the continuous oil pipe expansion cylinder. The power unit and the control chamber are sequentially arranged at the front part of the semitrailer, the injection head is rotatably arranged at the tail part of the semitrailer by a connection platform, and the continuous oil pipe expansion cylinder is connected onto the semitrailer by a pin shaft in an embedded manner. In the utility model, as all parts are installed on the semitrailer, the semitrailer has high integration level, is flexible, and strong in applicability, and can effectively reduce the operation cost. The injection head can rotate through the connecting platform, so that adjustment on different heights can be realized, the operation is convenient and the transportation convenience can be improved.
