DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more specific definition of the scope of protection of the present invention. Obviously, the embodiments described in the present invention are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Example 1: The specific structure of the utility model is as follows:

[0032] Please refer to the attached Figure 1-4 The utility model discloses a wire-taking constant tension device for a cross-linking production line. The wire-taking constant tension device is applied to a 6-35kV cross-linking production line.

[0033] The structure comprises a column 8 and a tension rod 4, with the first end of the tension rod 4 angled with the top of the column 8. The column 8 comprises a base and a pole secured to the base. The pole is welded to the base, which is then secured to the ground via four anchor bolts. Specifically, the column 8 is welded from a 40mm diameter galvanized steel pipe and a 350mm diameter, 12mm thick steel plate base.

[0034] The tension rod 4 is made of Ø40 galvanized steel pipe. A counterweight 3 is provided on the rod body of the tension rod 4, and the position of the counterweight 3 is adjustable. Figure 4 As shown, the counterweight 3 is sleeved on the rod body of the tension rod 4 and is locked by two fastening bolts 2. By loosening the two fastening bolts 2, the position of the counterweight 3 on the tension rod 4 can be adjusted.

[0035] The wire-winding constant tension device further includes an angle-adjustable structure for adjusting the angle between the upright column 8 and the tension rod 4 ; the angle-adjustable structure includes a first fixed block 5 and a second fixed block 7 .

[0036] The first end of the first fixing block is mounted on the body of the tension rod. The tension rod 4 is inserted through the first fixing block 5. The tension rod 4 is loosened and tightened by the first fixing block 5 to adjust its position. The first fixing block 5 has three screw holes through which the tension rod 4 passes. Each of these three screw holes is secured with a set bolt 2. Loosening the set bolts 2 allows the tension rod 4 to move within the fixing block 5. Tightening the three set bolts 2 on the first fixing block 5 secures the tension rod 4. By adjusting the position of the tension rod 4 and the counterweight 3, the insulated core of the medium-voltage cable can be properly tensioned.

[0037] A second fixing block 7 has a first end mounted on the vertical post and an adjustable position. The second end of the second fixing block 7 is rotatably connected to the second end of the first fixing block 5. Specifically, the second fixing block 7 has three screw holes provided in the hole body for engaging the vertical post. Each of the three screw holes is screwed with a set bolt 2. When the set bolts 2 are loosened, the second fixing block 7 can move up and down along the vertical post. When the three set bolts 2 on the second fixing block 7 are tightened, the second fixing block 7 is locked and fixed.

[0038] The second end of the second fixing block 7 and the second end of the first fixing block 5 are rotatably connected via a movable shaft 6. Specifically, one end of the movable shaft 6 is inserted into the second end hole of the first fixing block 5 and is tightened by the set bolt 2, and the other end of the movable shaft 6 is inserted into the second end hole of the second fixing block 7, so that the movable shaft 6 and the second fixing block 7 form a dynamic fit, allowing the movable shaft 6 to rotate.

[0039] Furthermore, the movable shaft 6 is equipped with a potentiometer. The potentiometer is used to work in conjunction with the take-up controller to more accurately control the tension. This utility model's take-up constant tension device meets the constant tension control requirements during the production of the insulated core of the medium-voltage cable, ensuring the quality of the medium-voltage cable.

[0040] Example 2:

[0041] The constant tension device for winding wire also includes a pressure roller assembly 1 installed at the second end of the tension rod 4. The pressure roller assembly 1 includes a pressure roller shaft 11, a pressure roller sleeve 12, two bearings 13 and a retaining spring 14. The first end of the pressure roller shaft 11 is vertically fixed to the second end of the tension rod 4. Specifically, the first end of the pressure roller shaft 11 is fixed to the second end of the tension rod 4 via a washer 9 and a nut 10. The pressure roller sleeve 12 is rotatably mounted on the pressure roller shaft 11 via two bearings 13. The retaining spring 14 is clamped to the second end of the pressure roller shaft 11 to prevent the pressure roller shaft 11 from detaching from the pressure roller shaft 11. The pressure roller shaft 11 is a circumferential arc structure that is narrow in the middle and wide on both sides. The pressure roller shaft 11 is a nylon rod pressure roller shaft.

[0042] The utility model provides a constant tension device for winding that meets the requirements of a 6-35kV cross-linked production line. When the production line is started, the pressure roller assembly 1 first ensures the slackness of the insulating core of the medium-voltage cable. Then, the pressure roller assembly 1 is pressed on the insulating core of the medium-voltage cable, and the counterweight block 3 is adjusted to adjust the tension to an appropriate size before tightening the fixing bolts. The height of the constant tension device for winding is achieved by adjusting the position of the second fixed block 7 on the vertical pole, and the angle of the wire pressing can be achieved by adjusting the position of the tension rod 4 on the first fixed block 5. The movable shaft 6 is equipped with a potentiometer for detecting the position of the tension rod 4. The potentiometer is connected to the winding controller of the production line to achieve interlocking control. When the tension rod 4 is higher than the set position, the winding motor slows down, and when the tension rod 4 is lower than the set position, the winding motor accelerates, thereby ensuring that the winding tension is constant. The quality of the insulating core of the medium-voltage cable is guaranteed.

[0043] In summary, the present invention's constant take-up tension device addresses the problem of excessive take-up tension reducing the diameter of the insulated core of a medium-voltage cable. The present invention features adjustable counterweights and tension rods, ensuring proper tension. The present invention's angle-adjustable structure adjusts the angle of the tension rod and column to maintain the proper tension on the insulated core of the medium-voltage cable.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
