The conveying device 5 comprises a plurality of trays 52 for receiving the oil pipe sections, the trays 52 move along a set path, so that the oil pipe sections pass through a plurality of operation stations, each operation station is provided with a device, and the devices on the operation stations are used for processing the oil pipe sections and joints subsequently installed on the oil pipe sections so as to produce a final high-pressure oil pipe finished product according to the working procedures. In order to facilitate continuous production, the distance between the devices on every two adjacent working stations is the distance of one step pitch, a plurality of trays 52 are arranged on the conveying device 5 at equal intervals, the trays can be synchronously translated and are translated by the distance of one step pitch every time, so that after the oil pipe section is processed by the front device, the trays 52 can move to the next working station with the oil pipe section, the rear device on the next working station continues to process the oil pipe section, meanwhile, the trays 52 on the previous working station of the front device are translated to the working station position of the front device and are continuously processed by the front device, and therefore the simultaneous online production of a plurality of oil pipe sections can be realized, the production beat is fast, and the efficiency is high.

It should be noted that the friction segment is not a fixed segment of the friction band 211, but a segment of the friction band 211 contacting the oil pipe material, and therefore, the friction segment is always changed from the friction band 211 itself because the oil pipe material is always fed in a running state.

In this embodiment, in order to further ensure the feeding accuracy, the friction belt 211 is a synchronous belt, and in order to maintain sufficient contact between the friction section and the oil pipe material, a plurality of rolling wheels 212 are arranged in a linear array on the inner side of the friction section of the friction belt 211, and the rolling wheels 212 are also synchronous wheels.

When the precision conveyor 2 and the tubing feeder 3 are operated cooperatively, the control system can detect the sagging state of the tubing material between the drawing component 35 and the precision conveyor 2 through the first sensing component 36 to determine whether the remaining amount of the tubing material between the drawing component 35 and the precision conveyor 2 meets the requirement, and prevent the tubing material between the drawing component 35 and the precision conveyor 2 from being straightened to affect the conveying precision of the precision conveyor 2, taking this embodiment as an example, in this embodiment, the first sensing component 36 includes three detecting sensors 361, a middle detecting sensor 361 and a lower detecting sensor 361, when the lowest detecting sensor 361 detects the tubing material below the detecting sensor, the remaining amount of the tubing material between the drawing component 35 and the precision conveyor 2 is detected to be larger, the drawing component 35 can maintain the current drawing speed, when the middle detecting sensor 361 detects the tubing material, the remaining amount of the tubing material is less, the operation speed of the pulling assembly 35 can be increased properly to make the oil pipe material hang down below the lower detecting sensor 361, when the uppermost detecting sensor 361 detects the oil pipe material, it indicates that the remaining amount of the oil pipe material is very small, at this time, the precise conveying device 2 can be slowed down or suspended, and the pulling assembly 35 can be accelerated, so that the precise conveying device 2 and the pulling assembly 35 can operate normally again when the remaining amount of the oil pipe material is large.

In order to coordinate the rotation speeds of the pulling assembly 35 and the feeding motor 33, so that the rotation speed of the feeding motor 33 is adapted to the pulling speed of the pulling assembly 35, a second sensing assembly 37 is further mounted on the first frame 31; the second sensing assembly 37 comprises an assembly seat 371, a transition wheel assembly 372 is slidably mounted on the assembly seat 371, and the oil pipe raw material led out from the rotating rack 32 passes through the transition wheel assembly 372 and then enters the traction device; an elastic element 373 is further mounted on the assembly seat 371, and in an initial state, the transition wheel assembly 372 is held at one end of the first frame 31 by the elastic element 373; a displacement sensor 374 for detecting the displacement of the transition wheel assembly 372 is also mounted on the assembly seat 371. By adopting the second sensing assembly 37, the control system detects whether the transition wheel assembly 372 translates through the displacement sensor 374 to judge whether the rotating speed of the feeding motor 33 is equal to the pulling speed of the pulling assembly 35, and the principle is as follows: under the normal state, the raw oil pipe material comes out from the rotating material frame 32 and then bypasses the transition wheel assembly 372 to turn a corner and then passes through the pulling assembly 35, when the rotating speed of the feeding motor 33 cannot follow the pulling speed of the pulling assembly 35, the raw oil pipe material between the pulling assembly 35 and the rotating material frame 32 can be shortened, so that the transition wheel assembly 372 can be pulled to slide relative to the assembly seat 371, and the reading of the displacement sensor 374 is reflected. When the control system determines that the rotation speed of the feeding motor 33 cannot follow the pulling speed of the pulling assembly 35, the control system may control the feeding motor 33 to increase the rotation speed, so that the transition wheel assembly 372 returns to the original position under the pushing of the elastic element 373. In this embodiment, a cylinder is used as the elastic element 373, which ensures sufficient thrust and certain elasticity for the transition wheel assembly 372.

In addition, because the oil pipe section needs to be cleaned, dried and pressed at each working station, the end of the oil pipe section sometimes needs to be extended out of the tray 52 in order to facilitate the operation of the end of the oil pipe section, and in order to facilitate the operation of extending and retracting the end of the oil pipe section out of the tray 52, the clamp 56 can be moved in a translational manner in the length direction of the tray 52, so that the integral movement of the oil pipe section can be facilitated; specifically, the lower end of the clamp seat 561 is provided with a slide block, the tray 52 is provided with a slide rail, and the slide block and the slide rail are in sliding fit.
