It should be understood that these embodiments are only used to illustrate this patent and not to limit the scope of this patent. In addition, it should be understood that after reading the content taught in this patent, those skilled in the art can make various changes or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims of the application.

[0026] See Figures 1-4 is a schematic structural diagram of this patent. A pipe fixing and traction device includes a bottom plate 1, a workbench 3 is installed on the bottom plate 1, a traction member 5 is installed in the middle of the workbench 3, and a fixing structure 4 is installed on the workbench 3. The number of the fixing structures 4 is two, and the fixing structures 4 are symmetrically distributed on both sides with the midline of the workbench 3 as the center;

[0027] The fixing structure 4 includes a U-shaped frame 401, a first roller 402, a second roller 403, a vertical groove 404, a round sleeve 405, and a bearing 406;

[0028] The U-shaped frame 401 is installed on the workbench 1. The first roller 402 is rotatably installed within the U-shaped frame 401. Vertical grooves 404 are respectively formed on both sides of the U-shaped frame 401. Circular sleeves 405 are respectively placed within the vertical grooves 404. Bearings 406 are respectively installed on both sides of the second roller 403, and the outer rings of the bearings 406 are respectively installed within the circular sleeves 405.

[0029] The fixing structure 4 includes a limit groove 407, bolts 408, and nuts 409. Limit grooves 407 are respectively formed on the sides of the vertical grooves 404. Bolts 408 are respectively installed on the side walls of the circular sleeves 405. The bolts 408 are respectively placed within the limit grooves 407, and nuts 409 are respectively sleeved on the bolts 408.

[0030] The fixing structure 4 includes a first pipe groove 410 and a second pipe groove 411. First pipe grooves 410 are respectively formed on the first roller 402 and the second roller 403. Second pipe grooves 411 are respectively formed on the first roller 402 and the second roller 403. The length ratio of the first pipe groove 410 to the second pipe groove 411 is 1:2.

[0031] When fixing and pulling a pipe with a diameter smaller than the first pipe groove 410, insert the pipe into the first pipe grooves 410 between the first roller 402 and the second roller 403 on both sides. Move the circular sleeves 405 outside the bearings 406 on the second roller 403 downward along the vertical grooves 404. The circular sleeves 405 drive the bolts 408 to move downward along the limit grooves 407, so that the first pipe grooves 410 between the first roller 402 and the second roller 403 clamp and fix the pipe. Then, screw the nuts 409 onto the bolts 408 to fix them. At this time, the traction member 5 drives the pipe, and the first roller 402 rotates within the U-shaped frame 401. At the same time, the second roller 403 rotates within the circular sleeve 405 through the bearing 406, positioning and fixing the pipe and pulling and conveying it. When fixing and pulling a pipe with a diameter larger than the first pipe groove 410 and smaller than the second pipe groove 411, select the second pipe grooves 411 between the first roller 402 and the second roller 403 for positioning and fixing, and pull and convey it through the traction member 5 to prevent the pipe from deviating during the process of fixing, pulling, and conveying.

[0032] A rotating block 6 is installed on the workbench 3, and a U-shaped plate 7 is installed on the bottom plate 1. The rotating block 6 is rotatably installed within the U-shaped plate 7 through a rotating shaft 8.

[0033] An adjusting structure 9 is installed between the bottom plate 1 and the workbench 3. The number of the adjusting structures 9 is two. The adjusting structures 9 are symmetrically distributed on both sides with the midline of the bottom plate 1 as the center. The adjusting structure 9 includes a first servo motor 10, a perforated vertical plate 11, a threaded rod 12, a threaded sleeve 13, a connecting plate 14, and a vertical block 15.

[0034] The first servo motor 10 is installed on the bottom plate 1. The first servo motor 10 is powered on and operates. The perforated vertical plate 11 is installed on the bottom plate 1. One end of the threaded rod 12 is installed on the output shaft of the first servo motor 10, and the other end of the threaded rod 12 is placed in the hole of the perforated vertical plate 11. The threaded sleeve 13 is sleeved on the threaded rod 12, and the threaded rod 12 is sleeved in the threaded hole of the threaded sleeve 13. The vertical block 15 is installed on the workbench 3. One side of the connecting plate 14 is rotatably connected to the threaded sleeve 13 through a pin shaft, and the other side of the connecting plate 14 is rotatably connected to the vertical block 15. When the height of the fixed pipe needs to be adjusted during traction and conveying, the output shaft of the first servo motor 10 drives the threaded rod 12 to rotate forward and backward on the perforated vertical plate 11, and the threaded sleeve 13 reciprocates along the threaded rod 12. At this time, the connecting plate 14 rotates on the threaded sleeve 13 and the vertical block 15 through the pin shaft respectively, so that the rotating block 6 on the workbench 3 rotates forward and backward on the U-shaped plate 7 on the bottom plate 1 through the rotating shaft 8 to adjust the height angle of the pipe during traction and conveying after being fixed.

[0035] The U-shaped frame 401 is installed on the workbench 3 through a connection structure, and the connection structure is correspondingly arranged with the U-shaped frame 401. The connection structure includes a screw 16 and a threaded groove 17;

[0036] The screw 16 is installed on the U-shaped frame 401, the threaded groove 17 is opened on the workbench 3, the screw 16 is sleeved in the threaded groove 17, and the screw 16 on the U-shaped frame 401 is screwed only in the threaded groove 17 on the workbench 3, so that the U-shaped frame 401 is installed on the workbench 3. Conversely, the first pipe groove 410 and the second pipe groove 411 of large size or small size can be replaced according to the diameter of the pipe for fixed traction and conveying (designed according to the size of the screw and the threaded groove, so that after the U-shaped frame is installed on the workbench, it can be horizontal with the workbench).

[0037] The traction member 5 includes an electric push rod 18, a second servo motor 19 and a round roller 20;

[0038] The electric push rod 18 is installed on the workbench 3, the second servo motor 19 is installed on the output end of the electric push rod 19. The electric push rod 18 and the second servo motor 19 are both powered on and operate. The round roller 20 is installed on the output shaft of the second servo motor 19. The surface of the round roller 20 is processed with anti-slip lines. According to the diameter of the pipe for fixed traction and conveying, the output end of the electric push rod 18 drives the round roller 20 to move up and down through the second servo motor 19, so that the round roller 20 always contacts the bottom end of the pipe, and the output shaft of the second servo motor 19 drives the round roller 20 to drive, so that the pipe is traction-conveyed.

[0039] Four rollers 2 are installed at the bottom end of the bottom plate 1. The four rollers 2 are distributed at the four corners of the bottom end of the bottom plate 1. The base 1 can be moved to a designated location through the rollers 2, and the rollers 2 are limited by an external car stopper.

[0040] When this patent works, screw 16 on U-shaped frame 401 is screwed into only threaded groove 17 on workbench 3, so that U-shaped frame 401 is installed on workbench 3. Base 1 can move to a designated location through roller 2, and roller 2 is limited by an external car stopper. When fixing and towing a pipe with a diameter smaller than the first pipe groove 410, the pipe is inserted into the first pipe groove 410 between the first roller 402 and the second roller 403 on both sides. The round sleeve 405 outside the bearing 406 on the second roller 403 moves downward along the vertical groove 404, and the round sleeve 405 drives the bolt 408 to move downward along the limit groove 407, so that the first pipe groove 410 between the first roller 402 and the second roller 403 clamps and fixes the pipe. Then, the nut 409 is screwed onto the bolt 408 for fixation. At this time, the towing member 5 drives the pipe, and the first roller 402 rotates within the U-shaped frame 401. At the same time, the second roller 403 rotates within the round sleeve 405 through the bearing 406, so that the pipe is positioned and fixed and towed and conveyed. When fixing and towing a pipe with a diameter larger than the second pipe groove 410 and smaller than the second pipe groove 411, the second pipe groove 411 between the first roller 402 and the second roller 403 is selected for positioning and fixing, and it is towed and conveyed through the towing member 5 to prevent the pipe from deviating during the process of fixing, towing and conveying. When the height of the fixed pipe needs to be adjusted during towing and conveying, the output shaft of the first servo motor 10 drives the threaded rod 12 to rotate forward and backward on the perforated vertical plate 11, and the threaded sleeve 13 reciprocates along the threaded rod 12. At this time, the connecting plate 14 rotates through the pin shaft on the threaded sleeve 13 and the vertical block 15 respectively, so that the rotating block 6 on the workbench 3 rotates forward and backward on the U-shaped plate 7 on the bottom plate 1 through the rotating shaft 8 to adjust the height angle of the pipe after fixing and before towing and conveying.
