Description

Technical Field

[0001] The utility model belongs to the technical field of pipe production equipment, and particularly relates to an RTP pipe traction machine. Background Art

[0002] Reinforced Thermoplastic Pipes (RTP pipes) are a type of high-pressure plastic composite pipes. RTP pipes have the characteristics of good flexibility, corrosion resistance, high pressure resistance, impact resistance, wear resistance, light weight, easy connection, coiling, and long-distance joint-free rapid laying. They can overcome the corrosion problem of steel pipes and the pressure resistance problem of plastic pipes. They can be used in oil and natural gas extraction, high-pressure long-distance transportation of natural gas, and various pipeline fields that require higher pressure to transport media.

[0003] With the existing traction machine, the pipe after being pulled by the traction machine is still some distance away from being transported to the cutting mechanism. At this time, the plastic pipe has not been completely cooled and shaped and is in a suspended state, which can easily cause the plastic pipe to bend and deform under the action of residual heat and its own gravity, thereby affecting the quality of pipe production. Utility Model Content

[0051] With the above structure, the second support rod 26 is first fixed by the fixing assembly 27, so that the second support rod 26 will not be displaced when supporting the telescopic guide plate 24. After the RTP tube is pulled out from the outlet end 12 of the tractor body 11, the RTP tube will move to the telescopic guide plate 24, and the first support rod 23 and the second support rod 26 support the RTP tube through the telescopic guide plate 24, so as to avoid the plastic tube from bending and deforming due to residual heat and its own gravity during transportation, thereby improving the production quality of the tube. Moreover, when the distance between the outlet end 12 on one side of the tractor body 11 and the cutting mechanism changes, the telescopic guide plate 24 is pulled to the right to extend the length of the telescopic guide plate 24, so as to solve the problem of the distance between the outlet end 12 on one side of the tractor body 11 and the cutting mechanism changing, thereby increasing the flexibility and practicality of the support assembly 2.

[0052] In a more specific embodiment, a fixing seat 29 that cooperates with the telescopic material guide plate 24 is provided at the top of the first support rod 23 and the second support rod 26, and the telescopic material guide plate 24 is threadedly connected to the fixing seat 29 through bolts. The telescopic material guide plate 24 can be disassembled and assembled by disassembling and assembling the bolts on the fixing seat 29, thereby increasing the convenience of disassembling and assembling the telescopic material guide plate 24.

[0055] Specifically, the model of the electric push rod 122 is GX-DC / E10, and its working principle is to use an electric motor as the power, and drive a lead screw nut through gear reduction or a worm gear to convert the rotational motion of the motor into the linear motion of the push rod along the guide rail, and use the forward and reverse rotation of the motor to realize the reciprocating forward and backward movement of the push rod. The corresponding principle structure of this section is not drawn in the attached figure.

[0056] In a more specific embodiment, a connecting groove 25 is provided on one side of the fixed groove 21, and a slide groove 262 cooperating with the slide plate 261 is provided inside the fixed groove 21 and the connecting groove 25. When the telescopic material guide plate 24 is pulled to the right to extend the length of the telescopic material guide plate 24, the second support rod 26 passes through the slide plate 261 and the slide groove 262, so that the second support rod 26 moves to the right along with the telescopic material guide plate 24, supports the telescopic material guide plate 24, and increases the stability of the telescopic material guide plate 24.

[0060] The anti-skid pad 273 is arranged at the bottom of the threaded rod 271. When the slide plate 261 is to be fixed, the threaded rod 271 is rotated to move the anti-skid pad 273 downward through the threaded sleeve 272, so that the threaded rod 271 drives the anti-skid pad 273 to support and squeeze the inner bottom of the fixing groove 21, thereby fixing the slide plate 261 and increasing the stability of the second support rod 26.

[0061] In a more specific embodiment, a first connecting plate 211 is disposed on the top of the fixing groove 21.

[0062] The fixing groove 21 is fixed by bolts. By disassembling and assembling the bolts on the fixing groove 21 , the fixing groove 21 can be disassembled and assembled, thereby increasing the convenience of disassembling and assembling the fixing groove 21 .
