Description

Technical Field

[0001] This utility model relates to the field of cable conduit forming technology, and in particular to a cable conduit forming device. Background Technology

[0002] Cable conduits are key components used in power, communications and other fields to protect cable lines. Their main function is to provide physical protection for cables, preventing them from being squeezed, impacted, corroded and mechanically damaged. At the same time, they facilitate the installation, maintenance and replacement of cables, and ensure the stable operation of the line. They are widely used in construction, municipal engineering, rail transit and other scenarios.

[0003] In the production of cable conduits, extrusion molding is the mainstream process. After the high-temperature molten plastic raw material is extruded through the mold, it needs to be cooled and shaped quickly. If the cooling is not timely or uniform, it will cause defects such as deformation, dimensional deviation and surface roughness of the conduit, which will affect the mechanical properties and safety of use.

[0004] However, after the conduit is formed, it is prone to deviation during transportation, making it inconvenient to use. Furthermore, when cooling it, it cannot be cooled in sections, and the conduit is prone to sudden cooling, which leads to stress concentration inside the pipe and a decrease in its mechanical properties. In view of this, this application proposes a cable conduit forming device. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] This utility model provides a technical solution: such as Figure 1-6 As shown, a cable conduit forming device includes a base plate 1. Multiple first electric telescopic rods 2 are symmetrically mounted on the top surface of the base plate 1. A cooling box 3 is mounted on the top of the multiple first electric telescopic rods 2. Openings 4 are provided at both ends of the cooling box 3. A fixed shaft 17 is fixedly mounted inside the base plate 1. Multiple rotating rods 18 are symmetrically rotatably connected to the outer side of the fixed shaft 17, and each pair of corresponding rotating rods 18 are arranged in a V-shape. A rotating roller 19 is rotatably connected to the inner side of each rotating rod 18. A roller 19 is mounted on the top wall of the base plate 1. There is a drive mechanism that drives the rotating rod 18 to rotate. Air-cooled bracket 11 and water-cooled bracket 12 are fixedly installed on the inner wall of the base plate 1. Multiple first nozzles 15 are fixed and connected to the inner side of the air-cooled bracket 11. Multiple second nozzles 16 are fixed and connected to the inner side of the water-cooled bracket 12. An air-cooling component is installed on the outer side of the base plate 1 and is connected to the air-cooled bracket 11. A water-cooling component is installed on the outer side of the base plate 1 and is connected to the water-cooled bracket 12. A controller 5 is fixedly installed on the outer side of the cooling box 3.

[0025] It should be noted that by having two rotating rods 18 arranged in a V-shape, the rotating rods 18 are driven to rotate by the drive mechanism, thereby changing the opening and closing angle of the two rotating rods 18. This makes it easier to lift conduits of different diameters and avoids lateral displacement of the conduits. In addition, the setting of the rotating roller 19 can change static friction to rolling friction, avoiding scratches or deformation of the pipe caused by rigid extrusion.

[0026] Furthermore, the drive mechanism includes multiple second electric telescopic rods 22, which are symmetrically installed on the top wall of the base plate 1. The bottom ends of the multiple second electric telescopic rods 22 located on the same side are all connected to a connecting plate 20. A push rod 21 is fixedly installed at the top of each connecting plate 20. A U-shaped seat 24 is slidably connected to the outside of each rotating rod 18, and the top of each push rod 21 is rotatably connected to the U-shaped seat 24 corresponding to the position. By lifting the push rod 21 upward, the included angle between the two rotating rods 18 can be reduced, and conversely, the included angle between the two rotating rods 18 can be increased.

[0027] Furthermore, the air-cooled assembly includes a fan 13, which is fixedly installed on the top surface of the base plate 1. One end of the fan 13 is connected to the air-cooled bracket 11. A dust filter plate 14 is installed at the top air inlet of the fan 13. The dust filter plate 14 can prevent external dust from contaminating the duct. By first cooling the duct with airflow, the duct can be initially cooled, avoiding stress concentration inside the pipe caused by rapid cooling.

[0028] Furthermore, the water-cooling assembly includes a water pump 8, which is fixedly installed on the top surface of the base plate 1. One end of the water pump 8 is connected to the water-cooling bracket 12 through a water injection pipe 9. A cooling device 7 is installed on the outside of the base plate 1 and is connected to the water pump 8. A water suction pipe 6 is fixed and connected to the outside of the cooling device 7, and the other end of the water suction pipe 6 is fixed and connected to the outside of the base plate 1. It should be noted that the cooling device 7 is a mature existing technology, which can cool the water flow and facilitate secondary cooling of the conduit.

[0029] Furthermore, a filter plate 10 is fixedly installed on the side wall of the base plate 1, and the height of the connection between the water pipe 6 and the base plate 1 is lower than the installation height of the filter plate 10.

[0030] Furthermore, each rotating rod 18 has two symmetrically formed T-shaped grooves 23 on its outer side, and each U-shaped seat 24 is slidably connected to the corresponding T-shaped groove 23. Each rotating roller 19 is covered with rubber on its outer side.

[0031] This utility model provides a cable conduit forming device, the specific working principle of which is as follows: First, according to the diameter of the cable conduit to be produced, the extension amount of the second electric telescopic rod 22 in the drive mechanism is set by the controller 5. When it is necessary to adapt to a large-diameter conduit, the second electric telescopic rod 22 extends, pushing the connecting plate 20 and the push rod 21 to move downward. The U-shaped seat 24 slides along the T-shaped groove 23 on the outside of the rotating rod 18, driving the rotating rod 18 to rotate outward around the fixed shaft 17, increasing the opening and closing angle of the two rotating rods 18. Conversely, if it is to adapt to a small-diameter conduit, the second electric telescopic rod 22 shortens, the push rod 21 is raised upward, and the U-shaped seat 24 drives the rotating rod 18 to rotate inward, reducing the included angle, so that the inner side of the rotating roller 19 forms a V-shaped support space that matches the diameter of the conduit.

[0032] Subsequently, the extruded high-temperature conduit enters from the opening 4 at one end of the cooling box 3 and falls onto the rotating rollers 19 of the multiple sets of V-shaped rotating rods 18. The weight of the conduit causes the rotating rollers 19 to roll, driving the conduit to be transported to the other end.

[0033] During this process, the air-cooled component starts first: the fan 13 draws in clean air through the dust filter plate 14 and sprays it onto the duct through the first nozzle 15 of the air-cooled bracket 11 to achieve initial cooling and reduce rapid cooling stress. When the duct moves to the area of ​​the water-cooled bracket 12, the water-cooled component starts: the water pump 8 delivers the cooled water from the refrigeration unit 7 to the second nozzle 16 through the water injection pipe 9 to perform secondary spray cooling on the duct. The cooled water flows into the base plate 1, and after being filtered by the filter plate 10 to remove impurities, it flows back to the refrigeration unit 7 through the water pumping pipe 6 for circulating cooling.

[0034] Meanwhile, the first electric telescopic rod 2 can adjust the height of the cooling box 3 to adapt to the height requirements of different production lines.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
