Abstract
The invention discloses a continuous pipe working device comprising an injection head, a continuous pipe, a vehicle body, a roller arranged on the vehicle body, a roller driving mechanism, and a rack pipe mechanism. One end of the continuous pipe is connected with the injection head, while the other end of the continuous pipe is fixed on the roller after penetrating through the rack pipe mechanism. The roller is used for winding the continuous pipe and can be driven by the roller driving mechanism to rotate. The rack pipe mechanism can guide the continuous pipe to move in the axial direction of the roller. The axis of the roller is parallel to the length direction of the vehicle body. As the axis direction of the roller of the continuous pipe working device is parallel to the length direction of the vehicle body, the length of the roller is increased and then the length of the continuous pipe wound on the roller is increased, therefore the working depth of the continuous pipe working device is increased.
