[0025] An embodiment of the present invention is shown in conjunction with Figures 1-7.

[0026] A traction device for drainage pipe inspection includes a base 1. An electric push rod 6 is installed on the inner wall of the base 1. One end of the electric push rod 6 is connected to a support platform 3. A drive motor 2 is installed on the outer surface of the support platform 3. A positioning seat 11 is connected to the upper surface of the support platform 3. A self-locking assembly 15 and a support assembly 12 are provided inside the support platform 3. A turntable 16 is located at the top of the support assembly 12. Symmetrical first cylinders 17 are connected to the upper surface of the turntable 16. Connecting plates 19 are hinged to the outer surfaces of both first cylinders 17. Second cylinders 18 are hinged to the interiors of both connecting plates 19. Symmetrical movable openings 20 are opened on the upper surface of the support platform 3. The tops of both second cylinders 18 extend into the interiors of the movable openings 20. Both clamping frames 10 are connected, and symmetrical first bearings 9 are embedded in the inner walls of both clamping frames 10. Threaded rods 21 are connected to the inner rings of both sets of first bearings 9. Movable blocks 22 are threaded onto the outer surfaces of both threaded rods 21. Arc plates 23 are connected to the sides of the two movable blocks 22 that are close to each other. A drive motor 2 enables the self-locking assembly 15 to rotate the turntable 16 via the support assembly 12, thus preventing the turntable 16 from rotating arbitrarily. A crank assembly is formed by the cooperation of the first cylinder 17, connecting plate 19, and second cylinder 18, thereby driving the clamping frames 10 to move in a relatively linear manner. The height of the arc plates 23 can be adjusted via the movable blocks 22 by rotating the threaded rods 21. The bearing platform 3 is pushed by the electric push rod 6, thereby pulling the pipeline.

[0027] In this embodiment, the support component 12 includes a second bearing 121, which is embedded in the inner bottom wall of the support platform 3. The inner ring of the second bearing 121 is connected to a support column 122, and the top end of the support column 122 is connected to the bottom surface of the turntable 16. By providing the second bearing 121, the support column 122 can be rotated and positioned. By providing the support column 122, the turntable 16 can be rotated.

[0028] In this embodiment, the self-locking assembly 15 includes two third bearings 151, both of which are embedded in the inner wall of the support platform 3. The inner rings of the two third bearings 151 are connected to a worm gear 152. A worm wheel 153 is connected to the outer surface of the support column 122. The worm gear 152 and the worm wheel 153 mesh with each other. The output end of the drive motor 2 is connected to one end of the worm gear 152 through the third bearings 151. The drive motor 2 rotates the worm gear 152. Due to the meshing relationship between the worm gear 152 and the worm wheel 153, the worm wheel 153 can be driven to rotate, thereby causing the support column 122 to rotate.

[0029] In this embodiment, the upper surface of the base 1 is provided with symmetrical sliding grooves 5, and sliders 4 are slidably connected inside the two sliding grooves 5. The upper surfaces of the two sliders 4 are connected to the bottom surface of the support platform 3. By sliding the support platform 3 in the sliding grooves 5 with the sliders 4, the support platform 3 can be supported.

[0030] In this embodiment, a limiting frame 13 is connected to the upper surface of the base 1, and a limiting bracket 14 is slidably connected inside the limiting frame 13. The upper surface of the limiting bracket 14 is connected to the bottom surface of the support platform 3. The limiting frame 13 limits the limiting bracket 14, thereby preventing the support platform 3 from separating from the base 1.

[0031] In this embodiment, the upper surface of the support platform 3 is connected to symmetrical fixing blocks 7, and the sides of the two sets of fixing blocks 7 that are close to each other are connected to sliding rods 8. The outer surfaces of the two clamping frames 10 are provided with symmetrical circular holes 25, and the outer surfaces of the two sliding rods 8 are slidably connected to the inner walls of the circular holes 25. By sliding the clamping frame 10 on the sliding rods 8, the clamping frame 10 can perform linear movement.

[0032] In this embodiment, the interior of each of the two clamping frames 10 is connected with a symmetrical limiting post 24. The outer surfaces of the two sets of limiting posts 24 are slidably connected to the interior of the movable block 22. By sliding the movable block 22 on the limiting post 24, the movable block 22 can be prevented from rotating with the threaded rod 21.

[0033] In this embodiment, a first protective pad 26 is connected to the upper surface of the positioning seat 11, and a second protective pad 27 is connected to the side of the two arc plates 23 that are close to each other. Both the first protective pad 26 and the second protective pad 27 are made of rubber, thereby preventing the arc plates 23 from causing damage to the pipeline.

[0034] Working principle: In use, first place the pipe on the positioning seat 11, then rotate the threaded rod 21 by gripping the handle to make the movable block 22 drive the arc plate 23 to move up and down, so that the arc plate 23 adapts to the height of the pipe. Then, the drive motor 2 drives the worm gear 152 to rotate through the third bearing 151. The worm gear 152 drives the worm wheel 153 to rotate. The worm wheel 153 drives the support column 122 to rotate. The support column 122 drives the turntable 16 to rotate. The turntable 16 drives the two first cylinders 17 to rotate. The two rotating first cylinders 17 drive the second cylinders 18 to move relative to each other through the connecting plate 19, so that the two clamping frames 10 drive the arc plate 23 to move closer to each other and clamp the pipe. Then, the electric push rod 6 pushes the support platform 3 to pull the support platform 3.

[0035] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
