[0025] such as Figures 1 to 6As shown in the figure, the utility model relates to a pipe fixing and traction device for pipe processing, which includes a base 1.

The outer wall of the support rod 8 and the inner wall of the traction roller 4 where it is penetrated are hermetically arranged. The inner end walls of the storage bins 7 are fixedly connected with springs 9. The other end of the spring 9 is fixedly connected with a push plate 10. The outer edge of the push plate 10 is slidably connected with the inner wall of the storage bin 7 and is hermetically arranged. Symmetrically arranged stop rods 11 are fixedly connected to the inner wall of the storage bin 7. A transmission rod 12 is rotatably connected to the top of the base 1. Symmetrically arranged thread grooves 13 are opened on the outer wall of the transmission rod 12. The transmission rod 12 penetrates through the limiting plate 3, and the thread grooves 13 are respectively threadedly connected with the inner walls of the through parts of the limiting plate 3 penetrated by the transmission rod 12. A first motor 14 is fixedly connected to the outer wall of the lower limiting plate 3. The main shaft of the first motor 14 penetrates through the limiting plate 3 and is fixedly connected to the end of the traction roller 4. By fitting the conveyor belt 6 with the pipe, the conveyor belt 6 is extruded by the pipe, so as to extrude the support rod 8, so that the support rods 8 start to move, and an arc arrangement state corresponding to the outer surface size of the pipe is formed between the support rods 8, so that the conveyor belt 6 plays a role in wrapping the pipe, so as to realize the fixation of the pipe. During the process of the conveyor belt 6 rotating to traction the pipe, the conveyor belt 6 continuously wraps the pipe, so as to ensure the stability when the pipe is tractioned, and it is also applicable to pipes of different sizes, with good convenience and practicability.

[0026] Furthermore, symmetrically arranged connecting rods 15 are fixedly connected to the top of the base 1. A support plate 16 is fixedly connected to the top of the connecting rod 15, and the end of the support plate 16 away from the connecting rod 15 is arc-shaped. By arranging the connecting rods 15 to support the support plate 16, the support plate 16 can support the pipe when the pipe enters between the conveyor belts 6, so as to prevent the pipe from tilting when it enters between the conveyor belts 6, so as to avoid affecting the fixed traction effect of the conveyor belt 6 on the pipe.

[0027] Furthermore, a plurality of uniformly arranged balls 17 are rotatably connected to the arc of the support plate 16. By arranging the balls 17, the wear between the pipe and the support plate 16 is prevented.

[0028] Furthermore, the connecting rod 15 is a telescopically adjustable structure; the telescoping of the connecting rod 15 can adjust the height of the support plate 16, so that the support plate 16 can support the pipe at different heights, increasing the versatility of the support plate 16.

[0029] Furthermore, a plurality of fastening screws 18 penetrating through the top of the base 1 are provided; by providing the fastening screws 18, the base 1 can be fixed to the pipe processing equipment or the ground, increasing the stability when fixing and pulling the pipe.

[0030] Furthermore, a second motor 19 is fixedly connected to the bottom of the base 1, and the main shaft of the second motor 19 penetrates through the base 1 and is fixedly connected to the lower end of the transmission rod 12; by providing the second motor 19, the transmission rod 12 can be driven to rotate by the second motor 19, thereby reducing the labor intensity of the staff.

[0031] Furthermore, a guide ring 20 is fixedly connected to the side of the support rod 8 away from the storage bin, a guide rod 21 is fixedly connected to the outer wall of the guide ring 20, a guide plate 22 is provided on two adjacent guide rods 21, guide grooves 23 are formed in the guide plates 22, and the guide grooves 23 are sleeved on the guide rods 21. By squeezing the support rod 8 through the guide ring 20, the support rod 8 gradually moves into the corresponding storage bin 7, thereby preventing the support rod 8 from getting stuck between the support rod 8 and the conveyor belt 6 during the rotation of the traction roller 4, resulting in the support rod 8 being unable to move into the storage bin 7, thus affecting the fixing effect of the pipe.

[0032] Working principle: This embodiment provides a pipe fixing and traction device for pipe processing. When in use, the pipe is inserted between the conveyor belts 6. Subsequently, the second motor 19 drives the transmission rod 12 to rotate. The rotation of the transmission rod 12 causes the limiting plates 3 to approach each other through the threaded grooves 13. The mutual approach of the limiting plates 3 drives the bearing rings 5 to approach each other through the traction rollers 4. The mutual approach of the bearing rings 5 causes the conveyor belts 6 to approach the pipe and clamp the pipe. At this time, the conveyor belts 6 will start to squeeze the support rods 8 under the pressure of contact and extrusion with the pipe, causing the support rods 8 to move towards the inside of the storage bin 7. A liquid is filled in the storage bin 7, so that when the support rods 8 move towards the inside of the storage bin 7, the liquid is squeezed, thereby causing the liquid in the storage bin 7 to start squeezing the push plate 10 to move. When the push plate 10 moves and contacts the stop rod 11, it is blocked by the stop rod 11, making the push plate 10 unable to continue moving. In this way, an arc arrangement state corresponding to the outer surface size of the pipe is formed between the support rods 8, so that the conveyor belts 6 play a wrapping role on the pipe, thereby realizing the fixation of the pipe. The first motor 14 operates to drive the traction rollers 4 to rotate. The traction rollers 4 drive the conveyor belts 6 to rotate through the bearing rings 5, so that the conveyor belts 6 drive the pipe to move. As the traction rollers 4 rotate, after the support rods 8 are not squeezed by the pipe through the conveyor belts 6, the spring 9 will push the push plate 10 to reset under its own elastic force, so that the push plate 10 pushes the liquid to push and squeeze the support rods 8, causing the support rods 8 to reset. In this way, the cycle realizes the fixed traction of the pipe;

[0033] And when the support rods 8 rotate with the traction rollers 4, the movement of the traction rollers 4 towards the inside of the storage bin 7 will synchronously drive the guide ring 20 to move together. The guide rods 21 on the guide ring 20 will squeeze one side of the guide plate 22 through the guide grooves 23 on the guide plate 22, making the guide plate 22 present an inclined state. And as the traction rollers 4 continue to rotate, the conveyor belts 6 will gradually squeeze the guide plate 22. Thus, the other side of the guide plate 22 squeezes the guide rods 21 on the support rods 8 that are about to contact the conveyor belts 6 through the guide grooves 23, so that the guide rods 21 on the support rods 8 that are about to contact the conveyor belts 6 gradually move the corresponding support rods 8 towards the inside of the storage bin 7 through the guide ring 20, thereby preventing the support rods 8 from getting stuck between the conveyor belts 6 during the rotation of the traction rollers 4, which may cause the support rods 8 to be unable to move towards the inside of the storage bin 7, thus affecting the fixing effect of the pipe.

Those of ordinary skill in the art can easily understand the spirit of this utility model according to the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of this utility model, they are within the protection scope of this utility model.
