[0017] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0018] This application discloses a stranding machine loading device for overhead conductor production. (Refer to...) Figure 1 It includes a workbench 1, and two sets of guide wheel sets 2 are provided on the surface of the workbench 1. The two guide wheel sets 2 are arranged in the horizontal direction, and each guide wheel set 2 includes two guide wheels, one upper and one lower, for transporting cables.
[0019] Reference Figure 1 , Figure 2 and Figure 3 The worktable 1 has two mounting slots 11 on its surface. Both mounting slots 11 are located between the two guide wheel groups 2 on both sides. The two mounting slots 11 are set in the horizontal direction and the length direction of the mounting slots 11 is set in the vertical direction. Each mounting slot 11 is equipped with a tension adjusting wheel group 3. The tension adjusting wheel group 3 includes a mounting plate 31, a mounting block 32, a tension wheel 33 and an adjusting cylinder 34.
[0020] Reference Figure 1 , Figure 2 and Figure 3 The mounting plate 31 is disposed in the mounting groove 11. An adjustment groove 311 is provided on the surface of the mounting plate 31. The adjustment groove 311 is opened in the vertical direction. The mounting block 32 is slidably disposed in the adjustment groove 311. The two side walls of the mounting block 32 abut against the inner side wall of the adjustment groove 311 to ensure that the mounting block 32 can slide in the vertical direction. The adjusting cylinder 34 is disposed on the bottom wall of the adjustment groove 311. The piston rod of the adjusting cylinder 34 is connected to the bottom wall of the mounting block 32 to drive the mounting block 32 to move along the length direction of the adjustment groove 311.
[0021] Reference Figure 1 , Figure 2 and Figure 3The bottom wall of the adjusting groove 311 is provided with several pads 312. A support arm 313 is vertically provided on the surface of the pad 312. A hydraulic damper 314 is provided between the support arm 313 and the bottom wall of the mounting block 32. The two ends of the hydraulic damper 314 are respectively connected to the support arm 313 and the mounting block 32. In this embodiment, the damping force of the hydraulic damper 314 is adjustable in the range of 50-500N, which can buffer the sliding of the mounting block 32 to prevent the mounting block 32 from falling due to component damage, thus preventing damage to the tension adjusting wheel group 3 and improving safety.
[0022] Reference Figure 1 , Figure 2 and Figure 3 The mounting block 32 has a buffer groove 324 on its surface. Two parallel limiting rods 325 are provided in the buffer groove 324. The limiting rods 325 are arranged vertically. A buffer block 326 is slidably connected to the limiting rods 325. Several elastic elements 327 are provided on the upper and lower surfaces of the buffer block 326. The elastic elements 327 abut against the inner wall of the buffer groove 324 and the buffer block 326. In this embodiment, the elastic element 327 is a disc spring assembly, which includes 5-8 disc springs. The total stroke of the disc spring assembly is 30-50mm, which is used to assist the hydraulic damper 314 in buffering.
[0023] Reference Figure 1 , Figure 2 and Figure 3 A rotating bearing 321 is provided on the surface of the buffer block 326. A rotating shaft 322 is provided on the inner ring of the rotating bearing 321. The rotating shaft 322 is rotatably connected to the buffer block 326 through the rotating bearing 321. A shaped block 323 is provided on the peripheral wall of the end of the rotating shaft 322 that extends out of the rotating bearing 321. In this embodiment, the shaped block 323 is rhomboid. A shaped groove 331 for inserting the shaped block is provided through the center of the tension wheel 33 along the thickness direction. A number of locking members 332 are provided on the surface of the tension wheel 33 for fixing the shaped block 323 to the tension wheel 33. The locking members 332 are metal sheets and bolts for fixing the tension wheel 33 to the shaped block 323, so that the tension wheel 33 rotates with the rotating shaft 322.
[0024] Reference Figure 1 , Figure 2 and Figure 3 Guide ring plates 333 are provided around both ends of the tension wheel 33. In this embodiment, both the tension wheel 33 and the guide ring plates 333 are made of polyurethane material. By setting the guide ring plates 333, the running trajectory of the cable is restricted to ensure the smooth operation of the cable.
[0025] The implementation principle of the overhead conductor production stranding machine loading device in this application embodiment is as follows: When the cable is loaded between the two guide wheel groups 2, the cable needs to pass through two tension adjusting wheel groups 3 in sequence. The tension wheel 33 of one tension adjusting wheel group 3 moves downward, while the guide wheel of the other group moves upward, so that the cable can be tensioned upward and downward respectively. This achieves tension adjustment of the cable, improves the problems caused by the lack of tension adjustment capability of the existing loading device, such as loose stranded structure, damage to the stranded surface, uneven electrical performance of the stranded wire, frequent wire breakage and jumper, and thus improves the quality and efficiency of overhead conductor production.
[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
