[0085] See 1 to Figure 5 As shown, Figures 1 to 5 A schematic diagram of the usage state of a fixing device provided in an embodiment of this application is shown.

[0086] An embodiment of this application provides a fixing device comprising: a clamping part 500, a fastening part 800, and an adjusting part 400. The clamping part 500 is connected to the tower 100; the fastening part 800 is connected to the cable 300; the adjusting part 400 is located between the clamping part 500 and the fastening part 800, the clamping part 500 is mounted on a first end of the adjusting part 400 (the upper end of the adjusting part 400 as shown in the figure), and the fastening part 800 is mounted on a second end of the adjusting part 400 (the lower end of the adjusting part 400 as shown in the figure); the adjusting part 400 is configured to adjust the distance between the first end and the second end of the adjusting part 400.

[0087] When assembling the suspension insulator 200, the suspension insulator 200 can be inserted into the central axis position of the adjustment part 400. The distance between the tower and the cable is adjusted by the fixing device so that the distance between the tower and the cable matches the suspension insulator, so that a specified number of suspension insulators can be installed between the cable and the tower pole. At the same time, the fixing device can also connect and fix the cable and the tower pole during the installation of the suspension insulator.

[0088] The structure of the adjusting part 400 is described in detail below. The adjusting part 400 includes: a support ring 401, a snap fastener 402, a connecting ring 403, a sliding inner groove 404, a positioning ring 405, and a control component 600. The top of the support ring 401 is provided with the snap fastener 402, and the clamping part 500 is snapped onto the support ring 401 via the snap fastener 402. The connecting ring 403 is located below the support ring 401, and the bottom of the connecting ring 403 is connected to the snap fastener 800. Sliding inner grooves 404 are provided at the bottom of the support ring 401 and the top of the connecting ring 403. The sliding inner grooves 404 on the support ring 401 and the connecting ring 403 generally need to be coaxial and relatively positioned to facilitate the arrangement of the control component 600. Two positioning rings 405 are respectively embedded in the sliding inner grooves 404 on the bearing ring 401 and the connecting ring 403, so that the positioning rings 405 can rotate within the sliding inner grooves 404 on the bearing ring 401 and the connecting ring 403. A control component 600 is installed between the two positioning rings 405, and the control component 600 can move along the axial direction of the positioning rings 405 to adjust the distance between the two positioning rings 405.

[0089] refer to Figure 6 As shown, Figure 6A schematic diagram of a control assembly provided in one embodiment of this application is shown. The control assembly 600 includes: two rotating rollers 601, transmission rods 602, a control wheel unit 603, a connecting belt 604, and four snap-fit ​​units 700. A plurality of transmission rods 602 are circumferentially mounted on the positioning ring 405, which is connected to the bearing ring 401. Adjacent transmission rods 602 are connected via universal joints. The control wheel unit 603 is fitted onto one of the transmission rods 602; the operation of the control wheel unit 603 first drives the transmission rod 602 connected to it to rotate axially around the transmission rod 602, and then sequentially drives the remaining transmission rods 602 to rotate axially around their respective transmission rods 602 via universal joints. The rotating rollers 601 are fitted onto the transmission rods 602, and the two rotating rollers 601 are symmetrically arranged relative to the control wheel unit 603. The upper end of the connecting belt 604 is wound around the rotating rollers 601. The rotating roller 601 is secured to the positioning ring 405 connected to the bearing ring 401 via a snap-fit ​​unit 700, and the tension band 604 is secured to the positioning ring 405 connected to the connecting ring 403 via a snap-fit ​​unit 700. The snap-fit ​​unit fixes the position of the snap-fit ​​unit 700 on the positioning ring 405, preventing relative slippage. In this embodiment, as the rotating roller 601 rotates with the transmission rod 602, the extension length of the tension band 604 wound around it can be adjusted to adjust the distance between the two positioning rings 405, thereby achieving position adjustment between the bearing ring 401 and the connecting ring 403.

[0090] In an alternative embodiment, combined with Figure 9 As shown, Figure 9 A partially enlarged structural schematic diagram of B is shown. The control wheel unit 603 includes a control worm and a control worm wheel. The control worm is rotatably mounted on the positioning ring 405 connected to the bearing ring 401; the control worm wheel is fitted onto the transmission rod 602, and the control worm wheel is meshed with the control worm. The control worm can be driven by a power source to rotate, thereby driving the control worm wheel to rotate. At this time, the transmission rod 602 connected to the control worm wheel can rotate around the axis of the transmission rod 602 as the control worm wheel rotates. In this embodiment, the control worm and control worm wheel achieve a unidirectional transmission effect of the control wheel unit 603 to the transmission rod 602, so that the transmission rod 602 forms a self-locking effect through the control wheel unit 603.

[0091] Optionally, refer to Figure 6 As shown, the control assembly 600 has six transmission rods 602 arranged in it, but the number of transmission rods 602 arranged is not limited to this.

[0092] See again Figure 6 and Figure 8 As shown, Figure 8 A partially enlarged structural schematic diagram of A is shown. Taking the snap-fit ​​unit 700 snapped onto the positioning ring 405 connected to the connecting ring 403 as an example, the snap-fit ​​unit 700 includes: a snap-fit ​​block 701, a detection block 702, and a snap-fit ​​inner block 703. The snap-fit ​​block 701 is snapped onto the positioning ring 405, and its position on the positioning ring 405 is fixed, preventing relative sliding. The snap-fit ​​inner block 703 is connected to the second end of the pull strap 604, and the snap-fit ​​inner block 703 is slidably snapped onto the snap-fit ​​block 701. The detection block 702 is snapped between the snap-fit ​​inner block 703 and the snap-fit ​​block 701. The detection block 702 can detect the snap-fit ​​status between the snap-fit ​​inner block 703 and the snap-fit ​​block 701, preventing the snap-fit ​​inner block 703 from sliding out of the snap-fit ​​block 701. Optionally, the detection block 702 can be equipped with a pressure element to achieve real-time pressure monitoring.

[0093] See Figure 7 As shown, Figure 7 A schematic diagram of the clamping part provided in an embodiment of this application is shown. The clamping part 500 includes: a connecting block 501, two snap-fit ​​brackets 502, a clamping bracket 503, and a guide block 504. One end of the connecting block 501 is installed at the first end of the adjusting part 400; one end of each of the two snap-fit ​​brackets 502 is hinged to one end of the connecting block 501 away from the adjusting part 400; the clamping bracket 503 is arranged along the opening and closing direction of the two snap-fit ​​brackets 502, wherein the opening and closing direction of the two snap-fit ​​brackets 502 is configured to be either a direction in which the two snap-fit ​​brackets 502 approach each other or a direction in which the two snap-fit ​​brackets 502 move away from each other; the clamping bracket 503 is connected to both snap-fit ​​brackets 502 simultaneously, and the opposite sides of the two snap-fit ​​brackets 502 are elastically abutting against the clamping bracket 503 respectively; the guide block 504 is connected to the side of the snap-fit ​​bracket 502 away from the connecting block 501, and the guide block 504 is respectively arranged on the opposite side of the two snap-fit ​​brackets 502.

[0094] The structure of the fastening part 800 is described in detail below. The fastening part 800 includes a fastening frame 801 and an adsorption plate 802. The fastening frame 801 has a hook-like structure and is used to hook the cable 300. The fastening frame 801 is hinged to the lower end of the adjusting part 400 (i.e., the lower end of the connecting ring 403), and the adsorption plate 802 is also installed at the lower end of the adjusting part 400 (i.e., the lower end of the connecting ring 403). When the fastening frame 801 is unhooked from the cable 300, the adsorption plate 802 is magnetically connected to the fastening frame 801, causing the fastening frame 801 to unfold away from the cable 300. When the fastening frame 801 hooks the cable 300, it grips the cable 300, and the adsorption plate 802 is not magnetically connected to the fastening frame 801; in other words, the adsorption plate 802 is not connected to the fastening frame 801 at this time. Referring to the attached diagram, the two fastening parts can be symmetrically positioned at the lower end of the connecting ring 403 to more securely grip the cable 300.

[0095] In one embodiment of this application, an auxiliary part 900 is further included. The auxiliary part 900 has a ring-shaped structure, with its inner ring end connected to the second end of the adjusting part 400, and its outer ring end located outside the adjusting part 400. During the assembly process of the suspension insulator 200, two types of parts are required. If a part falls, the auxiliary part 900 can act as a support and catcher, preventing damage from falling parts.

[0096] The structure of the auxiliary part 900 is described in detail below. The auxiliary part 900 includes a connecting rod 901, a support frame 902, and a support bag. The first end of the connecting rod 901 is connected to the second end of the adjusting part 400; the support frame 902 has a ring-shaped structure; the support frame 902 is sleeved on the outside of the adjusting part 400, and the support frame 902 is connected to the second end of the connecting rod 901; the support bag is placed on the support frame 902, and the support bag is connected to the support frame 902, the connecting rod 901, and the adjusting part 400.

[0097] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
