Description

Technical Field

[0001] The present invention relates to the technical field of agricultural planting, and specifically to an equipment for thermoplastic repair pipeline folding and forming from a circular pipe to an I-shaped pipe. Background Art

[0002] For the FIPP method of lining and repairing pipes, generally, the pipe needs to be extruded to reduce its volume so that it can be inserted into the pipe to be repaired. The currently used extrusion equipment, such as a pipe automatic extrusion forming equipment with the authorization announcement number CN214521861U, includes a bracket. One end of the bracket is fixedly installed with a first extrusion component for extruding the pipe up and down, the middle of the bracket is fixedly installed with a second extrusion component for extruding the two sides of the pipe, and the other end of the bracket is fixedly installed with a forming component for defining the shape of the pipe. By rotating the knob to drive the adjustment screw rod to rotate, the distance between the mounting frame and the forming turntable is adjusted. Thus, when the pipe body passes through the forming turntable, the forming turntable will push the materials on both sides of the pipe body inward to realize the extrusion forming of the pipe body. Through the free adjustment of multiple positions, the extrusion forming of pipes with different sizes can be satisfied, and thus the problem that the existing device cannot flexibly adjust the forming size is solved.

[0003] For the above-mentioned extrusion equipment, the pipe is first extruded into a square shape, and then the two sides are extruded and sunken. The pipe needs to be controlled at a high temperature state before extrusion. After it is extruded into a square shape, the two sides are extruded and sunken by the extrusion disks. Generally, the extrusion disks are in a rotating state. During extrusion, it is not easy to clamp and fix the pipe in a high temperature state because when clamping and fixing, the pipe in a high temperature state is prone to deformation. Generally, the conveying rollers convey slowly and stop conveying during extrusion. When the rotating extrusion disks extrude the front end of the pipe, since the pipe is not fixed, during the friction extrusion process, the pipe may be controlled to move forward, and the front end of the pipe is not extruded into the predetermined state. If the extrusion disks are in a non-rotating state, after the front end of the pipe is extruded, when subsequent extrusion is carried out, the pipe may need to be pushed, and for the pipe in a high temperature state, it may also deform when pushed forcefully.

Detailed implementation manners

[0025] The following further describes in detail the implementation manners of the present disclosure in conjunction with the drawings and embodiments. The detailed descriptions and drawings of the following embodiments are used to exemplarily illustrate the principles of the present disclosure, but cannot be used to limit the scope of the present disclosure. The present disclosure can be implemented in many different forms, not limited to the specific embodiments disclosed herein, but including all technical solutions falling within the scope of the claims.

[0026] Please refer to Figures 1-8, A thermoplastic repair pipeline forming equipment that folds from a circular pipe to an I-shaped structure, including a workbench 1. At both ends of the workbench 1, a first extrusion assembly and a second extrusion assembly are installed. The first extrusion assembly includes a double-shaft motor 5 fixedly installed at the upper end of the workbench 1 and two first threaded rods 11 rotatably connected to the workbench 1 (the thread directions at the upper and lower ends of the first threaded rod 11 are opposite). The working end of the double-shaft motor 5 is fixedly installed with a first bevel gear 16, and the upper end of the first threaded rod 11 is fixedly installed with a second bevel gear 17 meshing with the first bevel gear 16. A connecting block 13 is threadedly connected to the first threaded rod 11. A first extrusion roller 2 is rotatably installed between the two connecting blocks 13. The two first extrusion rollers 2 are respectively located above and below the pipeline 7. A protective housing 6 fixedly connected to the workbench 1 is arranged outside the first bevel gear 16 and the second bevel gear 17. When the pipeline 7 enters the workbench 1, first start the double-shaft motor 5 located on one side of the end of the pipeline 7. The double-shaft motor 5 controls the first extrusion rollers 2 above and below the pipeline 7 to move towards the pipeline 7 simultaneously. The second extrusion assembly includes a power motor 4 fixedly installed on the side of the workbench 1 and two rotating rods 18 rotatably installed in the workbench 1. The rotating rod 18 located above is a second threaded rod (the thread directions at the upper and lower ends of the second threaded rod are opposite), and the rotating rod 18 located below is a sliding column. The second threaded rod is fixedly connected to the output end of the power motor 4. An installation block 19 is arranged on the rotating rod 18. The installation block 19 is threadedly connected to the second threaded rod and is slidably connected to the sliding column. A second extrusion roller 12 is rotatably installed between the two installation blocks 19. The two second extrusion rollers 12 are respectively located on both sides of the pipeline 7. Then start the power motor 4 located on one side of the end of the pipeline 7. The power motor 4 controls the second extrusion rollers 12 on both sides of the pipeline 7 to move towards the pipeline 7 simultaneously. Through the sequential operation of the first extrusion roller 2 and the second extrusion roller 12, the end of the pipeline 7 is extruded into a square shape;

[0027] On both sides of the workbench 1, a third extrusion assembly is installed. On the lower wall of the workbench 1, a mounting plate 14 is fixedly installed. A first sliding opening 27 and two second sliding openings 29 are penetrated and opened at the upper end of the mounting plate 14. The third extrusion assembly includes a rotating column 31 that is in sliding contact with the second sliding opening 29. An extrusion disc 3 is fixedly installed at the upper end of the rotating column 31. A detection assembly for detecting the extrusion disc 3 is fixedly installed on the side wall of the workbench 1. A power assembly for controlling the movement of the two extrusion discs 3 to perform extrusion work is installed at the lower end of the mounting plate 14. The power assembly includes a first serrated plate 22 and two second serrated plates 15 that are slidably connected to the lower end of the mounting plate 14. The first serrated plate 22 and the second serrated plates 15 are arranged in a staggered manner. The lower end of the rotating column 31 penetrates the second sliding opening 29 and is rotatably connected to the second serrated plate 15. A first gear 33 that meshes with the second serrated plate 15 is rotatably installed at the lower end of the mounting plate 14. A second gear 26 that meshes with the first serrated plate 22 is fixedly installed at the lower end of the first gear 33. An electric push rod 34 for controlling the movement of the second serrated plate 15 is fixedly installed at the lower end of the mounting plate 14. A conveying assembly for controlling the rotation of the extrusion disc 3 is installed at the upper end of the mounting plate 14. The conveying assembly includes a working motor 24 fixedly installed on the first serrated plate 22. A first sliding rod 25 that is in sliding contact with the first sliding opening 27 is fixedly installed at the output end of the working motor 24. A second sliding rod 23 is rotatably installed on one of the second serrated plates 15. Connecting gears 21 and rotating gears 32 that mesh with each other are respectively fixedly installed at the lower ends of the second sliding rod 23 and one of the rotating columns 31. Pulley wheels 28 are fixedly sleeved on the other rotating column 31, the second sliding rod 23, and the first sliding rod 25. A conveying belt 30 is sleeved between the three pulley wheels 28. A controller 35 is fixedly installed on one side of the workbench 1. After the end of the pipeline 7 is extruded into a square shape, it is conveyed between the two extrusion discs 3. At this time, the conveying of the pipeline 7 stops. The electric push rod 34 is started to work, and the working motor 24 does not work, keeping the two extrusion discs 3 from rotating (to avoid rotation of the extrusion discs 3 during extrusion due to friction, which may cause the pipeline 7 to move forward without being properly extruded). The electric push rod 34 pushes the second serrated plate 15 connected to it to move. Through the cooperation of the first gear 33, the other second serrated plate 15 moves synchronously towards the pipeline 7, so that the two non-rotating extrusion discs 3 extrude the pipeline 7 and finally extrude it into an I-shaped shape. During the extrusion process, through the cooperation of the second gear 26, the first serrated plate 22 is synchronously pushed to move, so that the conveying belt 30 is always kept in a taut state. After the front end of the pipeline 7 is extruded, the electric push rod 34 stops working, and the working motor 24 is started to rotate. Through the cooperation of the pulley wheels 28, the conveying belt 30, the connecting gears 21, and the rotating gears 32, the extrusion disc 3 is controlled to rotate, giving the pipeline 7 a forward moving force, which can reduce the force for pushing the pipe at the rear side and reduce the possibility of deformation of the pipe due to strong pushing.

[0028] After the pipeline 7 moves to the positions of another first extrusion assembly and the second assembly, the auxiliary shaping is carried out according to the above steps.

[0029] As a further technical solution of the present invention, the detection component includes a fixed frame 8 fixedly installed on the workbench 1. The rotating column 31 penetrates through the fixed frame 8 and is in sliding contact with it. An arc-shaped housing 9 slidably connected to the fixed frame 8 is arranged outside the extrusion disc 3. Scanners 10 are fixedly installed at both the upper and lower ends of the arc-shaped housing 9. The scanners 10 are used to detect the protrusions and depressions on the surface of the extrusion disc 3. When the extrusion disc 3 works, it is in a state of long-term friction, and its surface is prone to damage. The scanners 10 detect the degree of damage to its surface, and if there is a problem, it can be timely feedback.

[0030] As a further technical solution of the present invention, two wiping rollers 20 are threadedly connected inside the arc-shaped housing 9. The wiping roller 20 is composed of a threaded shaft and a wiping rod. The threaded shaft is threadedly connected to the arc-shaped housing 9, which is convenient for disassembly and replacement. The wiping rod is rotatably connected to the threaded shaft. The two wiping rollers 20 are respectively in contact with the upper surface and the lower surface of the extrusion disc 3. The wiping rollers 20 can wipe off the impurities on the surface of the extrusion disc 3 to avoid affecting the detection.

[0031] Working principle:

[0032] When the pipe 7 is just transmitted to the inside of the workbench 1, first start the double-shaft motor 5 to control the rotation of the two first bevel gears 16. The two first bevel gears 16 respectively drive the rotation of the two second bevel gears 17. The two second bevel gears 17 respectively drive the rotation of the two first threaded rods 11, and control the first pressing rollers 2 above and below the pipe 7 to move towards the pipe 7 at the same time. Then start the power motor 4 to control the rotation of the second threaded rod, so that the two second pressing rollers 12 move towards the pipe 7 at the same time, and squeeze the end of the pipe 7 into a square shape;

[0033] After the end of the pipe 7 is squeezed into a square shape, it is transmitted between the two extrusion discs 3. At this time, the transmission of the pipe 7 stops. Start the electric push rod 34 to work, and the working motor 24 does not work, keeping the two extrusion discs 3 stationary (to avoid rotation of the extrusion discs 3 during extrusion due to friction, which may cause the pipe 7 to move forward before being properly extruded). The electric push rod 34 pushes the second serrated plate 15 connected to it to move. Through the cooperation of the first gear 33, the other second serrated plate 15 moves towards the pipe 7 synchronously, so that the two rotating columns 31 push the extrusion discs 3 to extrude the pipe 7, and finally extrude it into an I-shaped shape. During the extrusion process, since the first gear 33 drives the rotation of the second gear 26, the second gear 26 pushes the first serrated plate 22 to move, and the first serrated plate 22 drives the first sliding rod 25 to move, so that the conveyor belt 30 always remains in a taut state;

[0034] After the extrusion at the front end of the pipeline 7 is completed, the electric push rod 34 stops working, and the working motor 24 is started to rotate. The rotation of the extrusion disc 3 is controlled through the cooperation of the pulley 28, the conveyor belt 30, the connecting gear 21 and the rotating gear 32 (during the rotation of the extrusion disc 3, the damage degree of its surface is detected by the scanner 10, and if there is a problem, it can be timely feedback). A forward moving force is given to the pipeline 7, which can reduce the pushing force on the rear side of the pipe and reduce the possibility of deformation of the pipe due to strong propulsion;

[0035] After the pipeline 7 moves to the position of another first extrusion component and the second component, the auxiliary shaping is carried out according to the above steps.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art may make equivalent replacements for its features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
