[0041] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that for the convenience of description, only parts related to the present invention are shown in the drawings, rather than all the structures.

In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0045] As Figures 1 to 4 shown, the present invention provides a pipeline auxiliary processing and display device, which includes a frame 1 and a commutation unit 3, a moving unit 4 and a plurality of clamping mechanisms 2 arranged on the frame 1. The plurality of clamping mechanisms 2 are arranged in sequence along the length direction of the pipeline to be processed 100, and the distance between two adjacent clamping mechanisms 2 is adjustable. The clamping mechanism 2 is used for clamping the pipeline to be processed 100; the commutation unit 3 abuts against the pipeline to be processed 100, and the commutation unit 3 can drive the pipeline to be processed 100 to rotate around the axis; the moving unit 4 abuts against the pipeline to be processed 100, and the moving unit 4 can drive the pipeline to be processed 100 to move axially.

[0046] In this embodiment, a plurality of clamping mechanisms 2 are arranged in sequence along the length direction of the pipeline 100 to be processed, and each clamping mechanism 2 is used to clamp the pipeline 100 to be processed. Therefore, it can clamp various parts of the pipeline 100 to be processed along the length direction, ensuring the stability of the pipeline during processing. Since the distance between two adjacent clamping mechanisms 2 is adjustable, the clamping mechanism 2 can clamp and fix pipelines 100 to be processed with different lengths, thus expanding the applicable range of the pipeline auxiliary processing and display device; The commutation unit 3 and the moving unit 4 are both in contact with the pipeline 100 to be processed. Since the commutation unit 3 can drive the pipeline 100 to be processed to rotate along the axis and the moving unit 4 can drive the pipeline 100 to be processed to move along the axis, the pipeline auxiliary processing and display device has the ability to adjust the pipeline to rotate circumferentially and move axially, and can realize the flexible movement and precise positioning of the pipeline 100 to be processed, meeting the refined and diversified processing requirements for pipelines with different lengths. It can be understood that the pipeline auxiliary processing and display device can also be used for the fixed display of pipelines, and the commutation unit 3 and the moving unit 3 are used to adjust and move the pipelines to achieve a good display effect.

[0047] Specifically, as Figures 1 to 4 shown, two clamping mechanisms 2 are arranged on the frame 1. When clamping and fixing the pipeline 100 to be processed, the two clamping mechanisms 2 respectively clamp both ends of the pipeline 100 to be processed, thus ensuring the stability of the pipeline 100 to be processed; The pipeline auxiliary processing and display device further includes a driving power supply and a controller. The driving power supply is electrically connected to the clamping mechanism 2, the commutation unit 3, and the moving unit 4 to supply power to the above-mentioned parts, and the controller is used to control the start and stop of each part. Therefore, the staff can adjust the position and placement angle of the pipeline 100 to be processed according to actual needs.

[0048] The clamping mechanism 2 includes a top positioning member and a bottom positioning member. The top positioning member and the bottom positioning member are arranged at intervals in the height direction, and the top positioning member and the bottom positioning member are oppositely in contact with both sides of the pipeline 100 to be processed. The top positioning member and the bottom positioning member press and clamp the pipeline 100 to be processed from the upper and lower directions, thus ensuring the reliability of the pipeline auxiliary processing and display device to fix the pipeline 100 to be processed.

[0049] Specifically, as Figures 1 to 4As shown, the clamping mechanism 2 further includes a mounting frame 23. The top positioning member and the bottom positioning member are both arranged on the mounting frame 23. A slide rail 11 is arranged on the machine frame 1 along the axial direction of the pipeline 100 to be processed, and the mounting frame 23 is slidably arranged on the slide rail 11. In this embodiment, the pipeline auxiliary processing and display device has two clamping mechanisms 2, and each clamping mechanism 2 has a mounting frame 23. The two mounting frames 23 are both slidably arranged on the slide rail 11. Therefore, the distance between the two clamping mechanisms 2 can be adjusted by moving the mounting frame 23 along the slide rail 11 to meet the processing requirements of pipelines 100 to be processed with different lengths.

[0050] The specific structure of the mounting frame 23 can be set according to actual needs as long as it can ensure driving the top positioning member and the bottom positioning member to move along the slide rail 11. Exemplarily, as Figures 1 to 4 shown, the mounting frame 23 includes a base 231, a top plate 233 and a telescopic vertical rod 232. The base 231 is embedded in the slide rail 11, the top plate 233 is connected to the base 231 through the vertical rod 232, the top positioning member is arranged on the top plate 233, and the bottom positioning member is arranged on the base 231. In this embodiment, slide rails 11 are arranged on both sides of the machine frame 1, the base 231 of the mounting frame 23 is embedded on the slide rail 11, and two first lead screws 24 are respectively rotatably arranged on the machine frame 1 corresponding to the two mounting frames 23. The first lead screws 24 and the slide rail 11 are both arranged along the axial direction of the pipeline 100 to be processed. Threaded holes are formed in the base 231, and the first lead screw 24 is threaded through the threaded hole in a threaded fit with the base 231. The base 231, the first lead screw 24 and the slide rail 11 form a common lead screw guide device in the art. When the first lead screw 24 rotates forward, the base 231 moves along the slide rail 11 in the direction close to the end of the pipeline 100 to be processed. When the first lead screw 24 rotates reversely, the base 231 moves along the slide rail 11 in the direction away from the end of the pipeline 100 to be processed. The two first lead screws 24 are independently arranged, so that the individual movement of the two bases 231 can be controlled respectively, and thus the distance between the two mounting frames 23 can be adjusted flexibly, with a simple structure and convenient operation. The vertical rod 232 is a commonly used electric telescopic rod in the art. The fixed end of the vertical rod 232 is fixedly arranged on the base 231, the telescopic end of the vertical rod 232 is connected to the top plate 233, and the vertical rod 232 is electrically connected to the driving power supply and the controller, and can receive the instruction of the controller to extend or contract, so as to change the distance between the top positioning member and the bottom positioning member, thereby clamping and fixing pipelines with different diameters. Handwheels are installed at the ends of the two first lead screws 24 extending out of the machine frame 1 to facilitate the staff to rotate the first lead screws 24.

[0051] As Figures 2 to 5As shown in the figure, the bottom positioning member includes two bottom wheels 22, which are symmetrically arranged on both sides of the pipeline to be processed 100 and respectively abut against the pipeline to be processed 100; the top positioning member includes two top wheels 21, which are symmetrically arranged on both sides of the pipeline to be processed 100 and respectively abut against the pipeline to be processed 100; specifically, during the processing of the pipeline, the two bottom wheels 22 abut against the outer wall surface of the pipeline to be processed 100 from both sides and are tangent to the outer wall surface, and the two top wheels 21 abut against the outer wall of the pipeline to be processed 100 from both sides and are tangent to the outer wall surface, so as to realize the clamping and positioning of the pipeline to be processed 100. The bottom wheels 22 and the top wheels 21 are both made of rubber and can rotate freely under the action of external force, so as to avoid damaging the outer wall surface of the pipeline during the process of clamping the pipeline to be processed 100, and can cooperate with the pipeline to be processed 100 to realize rotation and commutation; it can be understood that the axes of the bottom wheels 22, the top wheels 21 and the pipeline to be processed 100 are parallel. The two bottom wheels 22 are arranged on the base 231 of the mounting frame 23, and the two top wheels 21 are arranged on the top plate 233 of the mounting frame 23.

[0052] In order to further improve the adaptation range of the pipeline auxiliary processing and display device, the two bottom wheels 22 are arranged on the mounting frame 23 with adjustable spacing, and the two top wheels 21 are arranged on the mounting frame 23 with adjustable spacing; specifically, as Figures 1 to 5As shown in the figure, a guide rod 25 and a rotatable second lead screw 26 are provided on the base 231 of the mounting bracket 23. The guide rod 25 and the second lead screw 26 are both arranged perpendicular to the axial direction of the pipe 100 to be processed. Two moving platforms 27 are sleeved on the guide rod 25, and the two moving platforms 27 are respectively in threaded engagement with the second lead screw 26. Two bottom wheels 22 are respectively rotatably arranged on the two moving platforms 27. The threads on the second lead screw 26 are divided into two sections, and the directions of the two sections of threads are opposite. One moving platform 27 is in engagement with one section of the thread, and the other moving platform 27 is in engagement with the other section of the thread. It can be understood that the guide rod 25, the second lead screw 26 and the moving platform 27 constitute a common lead screw guide device in the art. When the second lead screw 26 rotates forward, one of the moving platforms 27 moves along the guide rod 25 in the direction close to the pipe 100 to be processed. Since the two moving platforms 27 are in engagement with two sections of threads with opposite directions, the other moving platform 27 also moves along the guide rod 25 in the direction close to the pipe 100 to be processed, that is, the moving directions of the two moving platforms 27 are opposite and they approach each other. When the second lead screw 26 rotates reversely, the moving directions of the two moving platforms 27 are opposite and they move away from each other, so as to realize the adjustment of the distance between the two bottom wheels 22. In order to realize the synchronous adjustment of the top wheel 21 and the bottom wheel 22, a synchronous connecting rod 28 is provided on the mounting bracket 23. The top wheel 21 is adjustably arranged on the top plate 233 through a sliding plate. One end of the synchronous connecting rod 28 is fixedly connected to the moving platform 27 of the base 231, and the other end is fixedly connected to the sliding plate of the top plate 233. There are two synchronous connecting rods 28, which are respectively arranged corresponding to the bottom wheels 22 on both sides of the pipe 100 to be processed. When the second lead screw 26 rotates to drive the moving platform 27 to move, the moving platform 27 drives the sliding plate to move through the synchronous connecting rod 28, so as to realize the synchronous movement of the bottom wheel 22 and the top wheel 21 on the same side, and further ensure that the distances between the two bottom wheels 22 and the two top wheels 21 are equal, improving the positioning accuracy and reliability of the clamping mechanism 2 for the pipe 100 to be processed.

[0053] In another embodiment, the threads on the second lead screw 26 are arranged in the same direction, and the directions of the threads in the threaded holes on the two moving platforms 27 are opposite. Therefore, when the second lead screw 26 rotates, the moving directions of the two moving platforms 27 are opposite, and the adjustment of the two bottom wheels 22 can be realized.

[0054] Further, as Figure 3 and Figure 8As shown, the moving unit 4 includes a driving roller block 41. The driving roller block 41 abuts against the pipeline 100 to be processed, and the rotation of the driving roller block 41 can apply an axial frictional force to the pipeline 100 to be processed. The driving roller block 41 is arranged on the frame 1 and is located below the pipeline 100 to be processed. The driving roller block 41 can be a cylindrical structure or a regular prism structure. In this embodiment, the driving roller block 41 is a regular hexagonal prism structure. The driving roller block 41 is driven by a controller and a driving power source to rotate, and its rotation axis is perpendicular to the axis of the pipeline 100 to be processed. When the pipeline 100 to be processed does not need to be axially moved, the side surface of the driving roller block 41 faces the pipeline 100 to be processed above, and there is a gap between the driving roller block 41 and the pipeline 100 to be processed at this time. When the pipeline 100 to be processed needs to be axially moved, since the driving roller block 41 is a regular hexagonal prism structure, the diameter of the circumscribed circle of the end face of the driving roller block 41 is larger than the diameter of the inscribed circle. Therefore, when the driving roller block 41 rotates to the side edge facing the pipeline 100 to be processed, the side edge will abut against the outer wall surface of the pipeline 100 to be processed and drive the pipeline 100 to be processed to move axially by means of frictional drive. It can be understood that since when the pipeline 100 to be processed does not need to be axially moved, the side surface of the driving roller block 41 faces the pipeline 100 to be processed above, and there is a gap between the driving roller block 41 and the pipeline 100 to be processed at this time, the driving roller block 41 will not interfere with the rotation of the pipeline 100 to be processed around the axis for commutation, thereby improving the practicability of the pipeline auxiliary processing and display device.

[0055] As Figure 3 and Figure 8As shown, the mobile unit 4 also includes two auxiliary rollers 42, which are symmetrically arranged on both sides of the pipe 100 to be processed and respectively abut against the pipe 100 to be processed. The auxiliary rollers 42 can apply axial friction to the pipe 100 to be processed by rotating. The auxiliary rollers 42 can clamp the pipe 100 to be processed from both sides and drive the pipe to move synchronously with the driving rollers 41. Specifically, the mobile unit 4 also includes a carrier 43 and a first transmission assembly 44. The carrier 43 is connected to the frame 1 through an electric telescopic rod. The electric telescopic rod can drive the carrier 43 to approach or move away from the pipe 100 to be processed above in the height direction. The driving rollers 41 are rotatably arranged on the carrier 43. The two sides of the carrier 43 are An electric telescopic rod is horizontally provided at each end, and the electric telescopic rod can be extended and retracted in a direction perpendicular to the axis of the pipe 100 to be processed, and an electric telescopic rod that can be extended and retracted in the vertical direction is provided at the end of the horizontal electric telescopic rod. The auxiliary roller 42 is rotatably provided on the vertical electric telescopic rod. Through the cooperation of the above-mentioned horizontal electric telescopic rod and the vertical electric telescopic rod, the auxiliary roller 42 can move in the vertical and horizontal directions, thereby adapting to pipes of different sizes; the driving roller 41 and the auxiliary rollers 42 on both sides are connected by a first transmission assembly 44. The specific structure of the first transmission assembly 44 can be set according to actual needs, as long as the linkage between the driving roller 41 and the auxiliary roller 42 can be achieved. For example, Figure 1 and Figure 8 As shown, the first transmission assembly 44 includes a transmission shaft 441 and a first transmission belt 442. The transmission shaft 441 is rotatably set on the carrier 43 or the vertical electric telescopic rods on both sides. The driving roller 41 is passed through the transmission shaft 441. A mobile driving motor is provided on the carrier 43. The mobile driving motor is electrically connected to the driving power supply and the controller. The output end of the mobile driving motor drives the transmission shaft 441 to rotate through a gear. The positions on both sides of the transmission shaft 441 near the auxiliary rollers 42 are connected to the auxiliary rollers 42 through the first transmission belt 442; when the mobile driving motor is started, the transmission shaft 441 will be driven to rotate, and the driving roller 41 will be driven to rotate by the transmission shaft 441, and the auxiliary rollers 42 on both sides are driven to rotate through the first transmission belt 442, thereby realizing the synchronous rotation of the driving roller 41 and the auxiliary roller 42, so as to realize the axial drive of the pipeline 100 to be processed.

[0056] In this embodiment, the first transmission belt 442 is a belt with a toothed groove on the inner ring. The transmission shaft 441 is engaged with the toothed groove of the first transmission belt 442 through a gear, and the first transmission belt 442 is engaged with the matching gear on the auxiliary roller 42 through the toothed groove, thereby realizing transmission; a tensioning wheel can also be provided on the carrier 43 to keep the first transmission belt 442 taut, and the setting of the tensioning wheel belongs to the existing technology in this field, and its specific structure and setting method are not described in detail here.

[0057] likeFigure 3 and Figure 7 As shown in Figure 7 , the commutation unit 3 includes a driving wheel 31 rotatably arranged. The driving wheel 31 abuts against the pipeline 100 to be processed, and the outer peripheral surface of the driving wheel 31 is tangent to the outer peripheral surface of the pipeline 100 to be processed. Specifically, there are two driving wheels 31, and the two driving wheels 31 are arranged corresponding to the positions of the two bottom wheels 22, and the outer diameters of the driving wheel 31 and the bottom wheel 22 are the same. The two driving wheels 31 are respectively connected to the two moving platforms 27. That is, when the moving platform 27 moves, the driving wheel 31 and the bottom wheel 22 can move synchronously, so as to ensure that the driving wheel 31 and the bottom wheel 22 always abut against the pipeline 100 to be processed synchronously. Without additionally arranging a structure to move the driving wheel 31, the frictional driving of the driving wheel 31 on the pipeline 100 to be processed can be realized. It can be understood that the two driving wheels 31 are symmetrically arranged on both sides of the pipeline 100 to be processed, and the axes of the driving wheel 31, the pipeline 100 to be processed, the bottom wheel 22 and the top wheel 21 are parallel.

[0058] Specifically, as Figure 3 and Figure 7 shown in Figure 7 , a rubber sleeve is sleeved on the outer peripheral surface of the driving wheel 31, and tooth grooves are arranged on the surface of the rubber sleeve to increase the frictional force between the driving wheel 31 and the pipeline 100 to be processed, and avoid the situation that the pipeline rotation fails due to slipping. The two driving wheels 31 can both be driving wheels that rotate actively, or one can rotate actively and the other can rotate drivenly, as long as they can rotate synchronously to drive the rotation of the pipeline 100 to be processed. In this embodiment, the commutation unit 3 further includes a second transmission assembly 32. The second transmission assembly 32 includes a guide wheel frame 321 and a second transmission belt 322. One of the two driving wheels 31 is a driving wheel, and the other is a driven wheel. A commutation driving motor is arranged on one of the moving platforms 27. The commutation driving motor is electrically connected to the driving power supply and the controller. The output end of the commutation driving motor is connected to the driving wheel among the two driving wheels 31. The driving wheel is connected to the driven wheel through the second transmission belt 322. One end of the guide wheel frame 321 is fixedly connected to the moving platform 27, and a guide wheel is rotatably arranged at the other end of the guide wheel frame 321. The guide wheel abuts against the second transmission belt 322 from the inside of the second transmission belt 322 to keep the second transmission belt 322 in a taut state.

[0059] Specifically, the second transmission belt 322 is a belt with tooth grooves arranged on the inner circle. The guide wheel is provided with teeth, and the guide wheel meshes with the second transmission belt 322 through the teeth. Both of the two driving wheels 31 are provided with mating gears, and the second transmission belt 322 meshes with the mating gears to achieve effective transmission.

[0060] Furthermore, as Figure 3 and Figure 8As shown, since the auxiliary rollers 42 are symmetrically arranged on both sides of the pipe 100 to be processed and can abut against the pipe 100 to be processed, when the auxiliary rollers 42 do not rotate, the auxiliary rollers 42 can clamp and fix the pipe 100 to be processed, preventing the pipe 100 to be processed from rotating due to external force or inertia. Specifically, since the top wheel 21 and the bottom wheel 22 are both freely rotatable wheel structures, they cannot completely fix the pipe 100 to be processed. The auxiliary rollers 42 can keep the pipe 100 to be processed in a fixed state through friction. The specific operation process is as follows: First, the pipe 100 to be processed is placed between the top wheel 21 and the bottom wheel 22 to achieve clamping and positioning of the pipe 100 to be processed. Then, the staff adjusts the position of the auxiliary rollers 42 by controlling the carrier 43 on the mobile unit 4 and the electric telescopic rod connected to the auxiliary rollers 42 on the carrier 43, so that the auxiliary rollers 42 on both sides are pressed against the outer wall surface of the pipe 100 to be processed from both sides. Since the moving When the driving motor is turned off, the auxiliary rollers 42 are in a stationary and non-rotating state, thereby effectively preventing the pipe 100 to be processed from rotating due to external forces; when the reversing unit 3 is needed to drive the pipe 100 to be processed to rotate, the staff first controls the auxiliary rollers 42 on both sides to break away from contact with the outer wall of the pipe, and then starts the reversing driving motor. The driving wheel 31 will drive the pipe 100 to be processed to rotate around the axis. After rotating to the specified angle, the staff turns off the reversing driving motor and controls the auxiliary rollers 42 on both sides to stick to the outer wall of the pipe again, so that the pipe 100 to be processed remains stationary and prevents the pipe 100 to be processed from continuing to rotate under the influence of rotational inertia.

[0061] The specific structure of the auxiliary roller 42 can be set according to actual needs, as long as it can achieve effective contact with the outer wall of the pipe; for example, Figure 8 As shown, the auxiliary roller 42 is a regular hexagonal pyramid structure, and its side surface can be in contact with the outer wall surface of the pipe to be processed 100, thereby fixing the pipe to be processed 100; when the pipe to be processed 100 is axially moved by the moving unit 4, the auxiliary roller 42 cooperates with the driving roller 41 to drive the pipe to be processed 100 to move by friction driving; it should be noted that when the pipe to be processed 100 is driven to rotate by the reversing unit 3, the auxiliary roller 42 and the driving roller 41 have no contact with the outer wall surface of the pipe, so as to reduce the resistance when the pipe rotates.

[0062] Further, in order to reduce the resistance suffered by the pipeline 100 to be processed during axial movement, before driving the pipeline with the moving unit 4, the staff first makes the top positioning member disengage from the abutment with the pipeline 100 to be processed by extending the vertical rod 232, and then controls the auxiliary rollers 42 on both sides to approach each other and abut against the outer wall surface of the pipeline 100 to be processed. Since the auxiliary roller 42 has a regular hexagonal frustum structure, after its side surface abuts against the outer wall surface of the pipeline, the pipeline 100 to be processed will be subjected to an upward force from the auxiliary roller 42 and rise, thus disengaging from the contact with the bottom positioning member. After that, the staff starts the moving drive motor, and the drive roller 41 and the auxiliary roller 42 rotate synchronously to frictionally drive the pipeline 100 to be processed to move axially.

[0063] Further, as Figure 2 and Figure 9 shown, a traveling device 5 is provided on the frame 1. The traveling device 5 includes rollers 51, which facilitates the staff to move the frame 1. Specifically, the frame 1 is a rectangular parallelepiped frame structure, and the rollers 51 are arranged at the four corners of the frame 1. By providing the rollers 51, the pipeline auxiliary processing and display device can be moved according to the site requirements.

[0064] As Figure 2 and Figure 9 shown, the traveling device 5 further includes a locking assembly 52. The locking assembly 52 is used to position the frame 1 and prevent the frame 1 from moving freely on the ground. The specific structure of the locking assembly 52 can be set according to actual needs as long as it can prevent the frame 1 from moving freely. Exemplarily, there are four locking assemblies 52, which are respectively arranged at the corners of the frame 1 corresponding to the four rollers 51. The locking assembly 52 includes a lifting rod 521 and a support block 522. The lifting rod 521 is threadedly connected to the frame 1. The end of the lifting rod 521 is fixedly connected with the support block 522. The support block 522 has a cylindrical structure. An adjusting nut 523 is also fixedly provided on the lifting rod 521. When the adjusting nut 523 is screwed forward, the adjusting nut 523 will drive the lifting rod 521 to rotate and move downward, and the support block 522 will abut against the ground and lift the frame 1, so that the rollers 51 are disengaged from the ground. At this time, the frame 1 is fixed at a certain position on the ground. When it is necessary to move the pipeline auxiliary processing and display device, the adjusting nut 523 is screwed backward, the adjusting nut 523 will drive the lifting rod 521 to rotate and move upward, and the support block 522 will approach the frame 1 and disengage from the ground until the rollers 51 contact the ground. At this time, the frame 1 can move under the action of an external force.

[0065] Further, since there are two clamping mechanisms 2, the clamping mechanism 2 drives the two bottom wheels 22 to approach or separate from each other by rotating the second lead screw 26 to adapt to pipelines 100 to be processed with different sizes. In order to ensure the synchronism of the movement of the bottom wheels 22 on the two clamping mechanisms 2, as Figure 1 and6 As shown, the pipe auxiliary processing and display device further includes a third transmission assembly 6. The third transmission assembly 6 includes a third transmission belt 61 and sprockets 62. There are two sprockets 62, and the two sprockets 62 are respectively fixedly arranged at the ends of the two second lead screws 26 extending out of the base 231. The third transmission belt 61 is wound around the two sprockets 62. Tooth grooves are arranged on the inner wall of the third transmission belt 61, and the sprockets 62 are engaged with the third transmission belt 61 to achieve transmission. And a handwheel is also connected to the end of one of the second lead screws 26 extending out of the base 231, so as to facilitate the staff to rotate the second lead screw 26. When the second lead screw 26 rotates, the other second lead screw 26 rotates synchronously under the drive of the third transmission belt 61. In order to ensure the effectiveness of the transmission and improve the transmission efficiency, a tensioning wheel can also be provided for the third transmission assembly 6. The setting of the tensioning wheel belongs to the prior art in this field, and its specific structure and setting method will not be elaborated here.

[0066] To further improve the practicability and convenience of pipe processing, the pipe auxiliary processing and display device further includes a mounting bench 7, as Figure 5 and Figure 10 shown. The mounting bench 7 includes traveling wheels 71, a rack bar 72, a horizontal bar 73, a fixing table 74 and a traveling motor. A groove rail 12 is arranged on the side surface of the frame 1 along the axial direction of the pipe to be processed 100. The traveling wheels 71 are arranged in the groove rail 12 and the traveling wheels 71 roll and abut against the groove bottom surface of the groove rail 12. A through groove is opened on the side surface of the groove rail 12, and the traveling wheels 71 are clamped in the groove rail 12 through a pin shaft. The rack bar 72 is vertically connected to the traveling wheels 71, the horizontal bar 73 is connected to the top of the rack bar 72, and a fixing table 74 is arranged on the horizontal bar 73. The fixing table 74 is used to fix pipe processing equipment such as a grinding disc and a drilling machine. The processing equipment can be fixedly connected to the fixing table 74 through existing connection methods such as bolt connection, clamping and abutting. The specific connection method and connection structure will not be elaborated here. Both the horizontal bar 73 and the rack bar 72 are commonly used electric telescopic rods in this field, and can be telescoped to control the processing equipment on the fixing table 74 to move to a specified position, so as to facilitate the processing operation of the pipe to be processed 100. The bottom of the rack bar 72 is connected to the traveling wheels 71 through a connecting plate, and the traveling motor is installed on the connecting plate. The traveling motor is connected to a driving power source and a controller, and the output end of the traveling motor is connected to the pin shaft of the traveling wheels 71. Therefore, the traveling motor can drive the traveling wheels 71 to move along the groove rail 12.
