Description

Technical Field

[0001] This utility model relates to the field of pipe processing equipment technology, and in particular to pipe traction equipment. Background Technology

[0002] Pipe traction is a crucial step in pipe production and construction. It refers to applying tension to the pipe using mechanical devices to maintain a stable movement during extrusion molding. Pipe traction machines are used for this purpose. Most modern pipe traction machines are belt-type or wheel-type, using the rotation of a conveyor belt or wheels to pull the pipe. During traction, the friction between the rubber blocks and the pipe is utilized to achieve the traction effect. However, for different types of pipes (such as different sizes and shapes), the rubber blocks need to be replaced. Currently, most rubber blocks are installed using bolts, which is cumbersome and inconvenient to operate. Furthermore, the traction stroke is limited during traction, making it difficult to adjust according to actual needs. Utility Model Content

[0003] To overcome the technical defects of the existing technology, this utility model provides a pipe traction device, which has the advantages of easy replacement of traction rubber blocks, easy assembly according to needs, and easy adjustment of traction stroke.

[0004] The technical solution adopted in this utility model is: a pipe traction device, including a frame, on which a first rotating wheel and a second rotating wheel are symmetrically rotated and meshed. A servo motor is fixedly installed at the lower end of the frame, and the output end of the servo motor is fixedly connected to the lower end of the first rotating wheel. An airbag ring is fixedly installed on the outer side of the first rotating wheel and the second rotating wheel. Traction rubber blocks are magnetically attached to the airbag ring in a circumferential array. An air pump is fixedly installed at the lower end of the frame, located on one side of the servo motor. One end of the air pump is connected to the airbag ring. In use, the traction rubber blocks are replaced according to the shape and size of the pipe to be traction, and the pipe is clamped between the symmetrically distributed traction rubber blocks. The air pump inflates the inside of the airbag ring to adjust the clamping force of the traction rubber blocks on the pipe. During traction, the servo motor drives the first rotating wheel to rotate, and the friction between the traction rubber blocks and the pipe is used to achieve the effect of traction, which is convenient to use.

[0005] Preferably, gears are fixedly installed at the lower ends of the rotating shafts of both the first rotating wheel and the second rotating wheel. The first rotating wheel and the second rotating wheel mesh with each other through the gears. When the first rotating wheel rotates, the second rotating wheel rotates, thereby achieving the effect of traction and conveying the pipe.

[0006] Preferably, a rotary joint is fixedly installed on the upper end of both the first rotating wheel and the second rotating wheel. One end of the rotary joint is connected to the airbag ring, and a ventilation tube is fixedly installed on one end of the air pump. The other end of the ventilation tube is connected to the rotary joint. During inflation and deflation, the gas flows through the ventilation tube and the rotary joint to adjust the air volume inside the airbag ring, thereby adjusting the clamping force of the tube.

[0007] Preferably, mounting female seats are fixedly installed in a circumferential array on the airbag ring, and mounting male seats are fixedly installed on one side of the traction rubber block. The traction rubber block is installed on the mounting female seat through the mounting male seat. The magnetic adsorption between the mounting female seat and the mounting male seat facilitates quick assembly and disassembly of the traction rubber block.

[0008] Preferably, a magnet plate is embedded inside the mounting base, and positioning rods are fixedly installed at the four corners of the magnet plate inside the mounting base. When the mounting sub-base is installed on the mounting base, one end of the mounting sub-base is inserted into the positioning rod to facilitate limiting the position of the mounting sub-base.

[0009] Preferably, a metal plate is embedded in one side of the mounting base, and the metal plate is attracted to and connected to the magnetic plate. A positioning hole is opened on one side of the mounting base, and the positioning rod is inserted into the positioning hole. After installation, the metal plate is attracted to and connected to the magnetic plate, and the positioning hole improves the stability of the installation.

[0010] Preferably, the traction block is made of rubber material, and the traction block on the side opposite to the mounting base has an arc-shaped structure, which facilitates clamping the pipe and improves the traction effect on the pipe.

[0011] Preferably, connecting ears are symmetrically installed on both sides of the frame to facilitate assembly according to traction requirements.

[0012] The beneficial effects of this utility model are: by using magnetic installation of the traction rubber block, it is easy to quickly replace the traction rubber block, which is suitable for different types of pipes, convenient to operate, and improves the replacement efficiency of the traction rubber block. Furthermore, the airbag ring facilitates the adjustment of the clamping force during traction, and the connecting ear facilitates the assembly of several of these devices, thereby adjusting the traction stroke and making them suitable for different traction needs.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] like Figures 1-5 As shown, this embodiment provides a pipe traction device, including a frame 1. A first rotating wheel 2 and a second rotating wheel 3 are symmetrically rotated on the frame 1, meshing with each other. A servo motor 4 is fixedly mounted at the lower end of the frame 1, with its output end fixedly connected to the lower end of the first rotating wheel 2. An airbag ring 5 is fixedly mounted on the outer side of the first rotating wheel 2 and the second rotating wheel 3. Traction blocks 6 are magnetically attached to the airbag ring 5 in a circular array. An air pump 7 is fixedly mounted at the lower end of the frame 1, located to one side of the servo motor 4. One end of the air pump 7 is connected to the airbag ring 5. During use, the traction blocks 6 are replaced according to the shape and size of the pipe to be traction. The tube is installed on the airbag ring 5 and clamped between the symmetrically distributed traction blocks 6. The airbag ring 5 is inflated by the air pump 7, and the clamping force of the traction blocks 6 on the tube is adjusted. During traction, the servo motor 4 drives the first rotating wheel 2 to rotate. Since the first rotating wheel 2 meshes with the second rotating wheel 3, the second rotating wheel 3 rotates synchronously. The friction between the traction blocks 6 and the tube is used to achieve the effect of traction. It is easy to use. Connecting ears 17 are symmetrically installed on both sides of the frame 1. During assembly, it is easy to select several of these technical solutions according to the traction requirements and connect them through the connecting ears 17 with external bolts, which facilitates assembly.

[0021] As a technical optimization solution of this utility model, specifically as follows: Figure 3As shown, gears 8 are fixedly installed at the lower ends of the rotating shafts of the first rotating wheel 2 and the second rotating wheel 3. The first rotating wheel 2 and the second rotating wheel 3 mesh with each other through the gears 8. When the first rotating wheel 2 rotates, the second rotating wheel 3 rotates as well, and the rotation directions of the first rotating wheel 2 and the second rotating wheel 3 are opposite, so as to achieve the effect of traction and conveying the pipe. Rotary joints 9 are fixedly installed at the upper ends of the first rotating wheel 2 and the second rotating wheel 3. One end of the rotary joint 9 is connected to the airbag ring 5. One end of the air pump 7 is fixedly installed with a ventilation tube 10, and the other end of the ventilation tube 10 is connected to the rotary joint 9. The air pump 7 is a suction pump, which is convenient for inflating and deflating the airbag ring 5. During inflation and deflation, the gas volume inside the airbag ring 5 is adjusted through the ventilation tube 10 and the rotary joint 9, thereby adjusting the clamping force of the pipe. The use of the rotary joint 9 for ventilation avoids affecting the rotation of the first rotating wheel 2 and the second rotating wheel 3.

[0022] As a technical optimization solution of this utility model, specifically as follows: Figure 4 and Figure 5 As shown, mounting female seats 11 are fixedly installed in a circumferential array on the airbag ring 5, and mounting male seats 12 are fixedly installed on one side of the traction rubber block 6. The traction rubber block 6 is mounted on the mounting female seat 11 through the mounting male seat 12. The magnetic attraction between the mounting female seat 11 and the mounting male seat 12 facilitates the quick installation and removal of the traction rubber block 6, making it convenient to replace different types of traction rubber blocks 6 for different pipe materials. A magnet plate 13 is embedded inside the mounting female seat 11, and positioning rods 14 are fixedly installed at the four corners of the magnet plate 13 inside the mounting female seat 11. When the mounting male seat 12 is installed on the mounting female seat 11, one end of the mounting male seat 12 is inserted into the positioning rod 14, which facilitates the limiting of the mounting male seat 12, and the magnetic attraction facilitates the quick installation and removal of the traction rubber block 6. The iron plate 13 facilitates magnetic fixation of the mounting base 12. A metal plate 15 is embedded in one side of the mounting base 12, and the metal plate 15 is attracted to the magnetic plate 13. A positioning hole 16 is opened on one side of the mounting base 12, and the positioning rod 14 is inserted into the positioning hole 16. After installation, the metal plate 15 and the magnetic plate 13 are attracted to each other, which facilitates connection. The positioning hole 16 prevents the mounting base 12 from sliding on the mounting female base 11 after installation, thus improving the stability of the installation. The traction rubber block 6 is made of rubber material, and the traction rubber block 6 on the opposite side of the mounting base 12 has an arc-shaped structure, which facilitates clamping of the pipe, increases the contact surface with the pipe, increases friction, and improves the traction effect on the pipe.
