Description

Technical Field

[0001] This utility model belongs to the field of cable technology, and specifically relates to a pipe support roller device suitable for the production process of vertical tower cables. Background Technology

[0002] With the continued growth in market demand for high-voltage and ultra-high-voltage cables, vertical tower cable production technology has been widely adopted in China. By arranging production equipment vertically, vertical tower cable production effectively reduces or avoids problems such as cable eccentricity and abrasion caused by the cable's own weight and traction tension, thus significantly improving cable production quality and stability. However, existing vertical tower production technology has certain drawbacks during cable turning. For example, when the cable turns from vertical to horizontal, if the traction speed exceeds the extrusion speed, the cable turning angle is too small, causing the cable to scrape against the pipe wall; conversely, if the traction force is too small, the cable's own weight can also cause scraping, ultimately leading to serious quality problems. Utility Model Content

[0003] In view of this, the present invention provides a pipe support roller device suitable for the production of vertical tower cables. This device prevents the cable from colliding with the pipe at corners when the cable changes from a vertical to a horizontal direction, reducing friction between the cable and the pipe and improving product quality. The present invention is implemented as follows: It provides a pipe support roller device suitable for the production process of vertical tower cables, comprising two positioning sleeves, a support roller, and a support shaft. The support shaft is fixedly connected to the inner wall of the positioning sleeve, and the support roller is rotatably connected to the support shaft. The surface of the support roller is arc-shaped, and the outside of the support roller is covered with silicone. One positioning sleeve is used to connect the vertical cross-linking pipe, and the other positioning sleeve is used to connect the horizontal cross-linking pipe. Further improvements can be made: the support roller is a cylinder with a concave center and convex sides. The beneficial effects of adopting the above further solution are: it can greatly increase the contact area between the support roller and the cable in the working state, thereby reducing stress concentration, reducing roller deformation, improving the load-bearing capacity of the device, and increasing its service life. Furthermore, the support roller is coaxially arranged with the support shaft, and bearings are provided on the support roller at both ends. The advantage of this further solution is that it ensures the support roller can roll around the shaft. Furthermore, two first through holes are formed on the positioning sleeve, through which the support shaft passes and is fixedly connected to the positioning sleeve by bolts. Furthermore, the first through holes are located on the minor arc formed by the two first through holes, and the straight-line distance between the two first through holes is less than the diameter of the inner wall of the positioning sleeve. The advantage of this further solution is that it facilitates placing the support roller in a better position to support the cable. Furthermore, the positioning sleeve includes a first side and a second side on both sides, and the outer diameter of the first side and the second side is the same as the inner diameter of the positioning sleeve. The advantage of this further solution is that it connects the cross-linking pipe at the edge. Furthermore, the first side and the second side are in contact with the inner surface of the cross-linking pipe. Furthermore, a sealing ring made of rubber is provided at the connection between the first side, the second side, and the positioning sleeve. The advantage of this further solution is that it facilitates fixing the positioning sleeve. Furthermore, the outer diameter of the positioning sleeve is the same as the outer diameter of the cross-linking pipe. Furthermore, both the positioning sleeve and the support roller are made of steel.

[0004] The positioning sleeve is made of stainless steel, which has high strength and minimal deformation. The support roller is also made of stainless steel and coated with silicone to prevent scratches on the cable during rolling. Compared with existing technologies, the advantages of this utility model for a pipe support roller device suitable for vertical tower cable production processes are: by setting up this support roller device, friction can be effectively reduced when guiding L-shaped cables from vertical to horizontal, avoiding the risk of scratching the pipe and ensuring the stability and quality of the cable; the support roller is a cylinder with a concave middle and convex ends, which increases the contact area with the cable, reduces stress concentration, improves the load-bearing capacity of the device, and increases its service life.

[0013] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0014] like Figure 1-7As shown, this utility model provides a pipe support roller device suitable for the production process of vertical tower cables. It includes two positioning sleeves 10, a support roller 20, and a support shaft 30. Two first through holes 13 are opened on the positioning sleeves 10. The support shaft 30 passes through the first through holes 13 and is fixedly connected to the positioning sleeves 10 by bolts 131. Bearings 50 are provided at both ends of the support roller 20. The support roller 20 is rotatably connected to the support shaft 30 through the bearings 50. The support roller 20 is a cylinder with a concave middle and convex sides, which facilitates the placement of cables, makes the cables easy to move, and prevents them from contacting the inner wall of the cross-linking pipe. The support roller 20 is covered with silicone. Since the support roller 20 is made of steel, it is easy to scratch the cable. By wrapping the support roller 20 with silicone, the scratches on the cable can be reduced.

[0015] Two positioning sleeves 10 are used to connect the cross-linking pipe. The tower cable is usually L-shaped. One positioning sleeve is set on the cross-linking pipe in the vertical direction and the other positioning sleeve is set on the cross-linking pipe in the horizontal direction to prevent the cable from colliding with the pipe at the L-shaped corner.

[0016] On the vertical cross-linking pipe, the two first through holes 13 on the positioning sleeve 10 form a minor arc in the same direction as the horizontal cross-linking pipe. On the horizontal cross-linking pipe, the support roller 20 of the other positioning sleeve 10 is located at the lower part of the cable.

[0017] The positioning sleeve 10 has two sides, including a first side 11 and a second side 12. The outer diameter of the first side 11 and the second side 12 is the same as the inner diameter of the positioning sleeve 10. The first side 11 and the second side 12 are in contact with the inner surface of the cross-linking pipe. A sealing ring is provided at the connection between the first side 11, the second side 12 and the positioning sleeve 10 to ensure the airtightness during connection. In use, the positioning sleeve 10 is set on the cross-linking pipe of the L-shaped channel. During the vertical tower production process, the cable passes through the pipe vertically. One positioning sleeve 10 is set on the cross-linking pipe before the turn, and the other positioning sleeve 10 is set on the horizontal cross-linking pipe after the turn. Due to the dragging force, when the cable turns, it will generate a horizontal component force towards the inner wall, so that the cable is close to the support roller 20, but not close to the inner wall of the opposite side of the support roller 20. When moving horizontally, the cable will be close to the support roller 20 set in the horizontal direction of the cable due to its own weight.

[0018] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
