[0003] After searching, the utility model patent with Chinese application number CN201920160934.X discloses a new type of coiled tubing operation vehicle group, which comprises a transport vehicle, an oil conveying device and an oil guiding device. The top of the transport vehicle is connected with the bottom of the oil conveying device, and the bottom of the oil conveying device is connected with the top of the oil guiding device. The oil conveying device is composed of an oil conveying pipe, a filter sleeve, a roller, a support frame, a control box, an oil pump, a driving belt, a driving gear, a servo motor, a driven gear, an oil tank and a monitoring head. The oil outlet of the oil conveying pipe is connected with the oil inlet of the oil pump, and the oil outlet pipe of the oil pump is connected with the oil inlet of the oil tank. The inside bottom of the control box is connected with the base of the servo motor, the output shaft of the servo motor is connected with the shaft center of the driving gear, and the inner wall of the support frame is connected with the two ends of the roller.

[0004] When the transport vehicle reaches the oil well, the staff manually puts the filter sleeve into the oil well mouth, and then controls the servo motor to drive the driving gear to rotate counterclockwise, so that the driving belt drives the driven gear to rotate counterclockwise, and the roller on the support frame rotates counterclockwise, so that the oil conveying pipe wound on the roller gradually enters the inside of the oil well. By starting the oil pump, the oil in the oil well gradually enters the oil tank.

[0005] When the transport vehicle is not convenient to park near the oil well mouth, it is not convenient to adjust the position of the roller. The oil conveying pipe on the roller will fall on the ground beside the transport vehicle due to gravity, and people need to lift the oil conveying pipe to the inside of the oil well mouth, thereby increasing the workload of people and reducing the practicality of use.
