Description

Technical Field

[0001] This utility model relates to the field of wire pulling technology, and in particular to a power wire pulling device. Background Technology

[0002] Power line guy wire devices are important devices used in power systems to stabilize supporting structures such as power poles. They include: ordinary guy wires, corner guy wires, and high-pile guy wires.

[0003] In overhead power lines, poles are subjected to various external forces such as conductor tension and wind force. Existing power guy wire devices can effectively balance these external forces by setting guy wires, preventing poles from tilting or falling and ensuring that poles are stable and upright.

[0004] However, in practical applications, existing ordinary guy wires typically use UT-type clamps to connect the guy wire rod and the guy wire, using the tension of the guy wire to wedge and fix it. However, this fixing method only relies on friction in one direction. When the guy wire is subjected to reverse vibration, alternating load, or long-term fatigue, the wedge block is prone to slippage, resulting in the decrease of guy wire tension, which is not conducive to improving the stability of the pole.

[0005] Therefore, this application provides a power cable pulling device to meet the requirements. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a power cable pulling device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a power cable puller device, comprising a puller body, and further comprising:

[0008] A reinforcement component is placed at one end of the pull wire body. The reinforcement component includes a housing at one end of the pull wire body and a wire clamp inside the housing. Both ends of the wire clamp are connected to a serrated plate. The serrations on both sides of the serrated plate are arranged in opposite directions. A snap-fit ​​plate is provided on the side of the housing near the serrated plate. The snap-fit ​​plate snaps into the serrated plate.

[0009] A bonding assembly is placed on both sides of the reinforcing assembly and is used to bond the snap-fit ​​plate to the serrated plate. The bonding assembly includes a movable plate disposed on the housing near the snap-fit ​​plate. A spring is connected to the movable plate near the snap-fit ​​plate, and the spring is kinetically connected to the snap-fit ​​plate.

[0010] Furthermore, a slider is connected to the side of the serrated plate near the outer shell, and the serrated plate is slidably connected to the outer shell through the slider.

[0011] The beneficial effects of adopting the above-mentioned further solution are: the slider and the slide groove cooperate to limit the movement path of the wire clamp and reduce the friction between the wire clamp and the outer shell, ensuring the movement of the wire clamp inside the outer shell, and realizing the wire clamp driving the pull wire body to adjust the tightness.

[0012] Furthermore, a pull bar is provided on the side of the outer casing away from the pull bar body, and an annular connector is connected between the pull bar and the outer casing.

[0013] The beneficial effect of adopting the above-mentioned further scheme is that the bottom of the guy rod is buried at an angle in the ground, so that the angle between the outer shell and the pole is 45 degrees, which helps to improve the stability of the pole.

[0014] Furthermore, a snap-fit ​​block is connected to the side of the snap-fit ​​plate near the movable plate, and the snap-fit ​​plate snaps into the movable plate through the snap-fit ​​block.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the snap-fit ​​plate slides inside the snap-fit ​​groove through the snap-fit ​​block, and prevents the snap-fit ​​plate from separating from the movable plate.

[0016] Furthermore, a threaded post is rotatably provided on the side of the outer shell near the movable plate. The threaded post is threadedly connected to the movable plate, and the movable plate is slidably connected to the outer shell through the threaded post.

[0017] The beneficial effects of adopting the above-mentioned further solution are: the movable plate and the serrated plate work together to adjust the elasticity of the spring, which makes it easier to adjust the degree of engagement between the serrated plate and the snap-fit ​​plate, and helps to improve the adjustment and fixation of the wire clamp inside the housing.

[0018] Furthermore, a nut is connected to one end of the threaded post near the movable plate.

[0019] The beneficial effect of adopting the above-mentioned further solution is that it allows the movable plate to compress the spring sheet and squeeze the snap-fit ​​plate to snap into place with the serrated plate, which helps to improve the stability of the connection between the outer shell and the wire clamp.

[0020] Furthermore, an anti-slip coating is provided on the side of the active plate near the outer shell.

[0021] The beneficial effect of adopting the above-mentioned further solution is that the anti-slip coating, together with the nut, strengthens the connection between the movable plate and the outer shell, thereby improving the stability of the connection between the movable plate and the outer shell.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] 1. By setting up reinforcement components, the serrated plate and the snap-fit ​​plate achieve mechanical interlocking through their matching serrated structure, which enhances the anti-slip performance. The serrations on both sides of the serrated plate are in opposite directions, giving the serrated plate a bidirectional clamping function. This effectively resists unidirectional or bidirectional sliding caused by external forces, improves the stability of the connection between the guy wire and the clamp, and effectively reduces the loosening problem caused by vibration of traditional clamps. This helps to reduce the loosening of traditional clamps caused by vibration and improves the stability of the pole.

[0024] 2. By setting up the bonding component, during long-term use, the snap-fit ​​plate and the sawtooth plate will wear down due to frequent contact, resulting in a gap between them. At this time, the spring sheet will continuously apply a pushing force to the snap-fit ​​plate by the elastic force generated by its own elastic deformation, so that the snap-fit ​​plate will re-tightly bond with the sawtooth plate, ensuring that the snap-fit ​​plate and the sawtooth plate can always maintain precise engagement. Even under wear conditions, the stability of the connection between the snap-fit ​​plate and the sawtooth plate can be maintained, ensuring the stability of the connection.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] like Figures 1-6 As shown, this utility model provides a technical solution: a power cable puller device, including a puller body 1, and further comprising:

[0037] like Figures 1-4 As shown, the reinforcement component 2 is placed at one end of the pull wire body 1. The reinforcement component 2 includes a housing 21 disposed at one end of the pull wire body 1 and a wire clamp 22 disposed inside the housing 21. Both ends of the wire clamp 22 are connected to a serrated plate 23. The serrations on both sides of the serrated plate 23 are arranged in opposite directions. A snap-fit ​​plate 24 is disposed on the side of the housing 21 near the serrated plate 23. The snap-fit ​​plate 24 snaps into the serrated plate 23.

[0038] like Figures 1-5 As shown, the bonding component 3 is placed on both sides of the reinforcing component 2 and is used to bond the snap-fit ​​plate 24 and the serrated plate 23. The bonding component 3 includes a movable plate 31 disposed on the housing 21 near the snap-fit ​​plate 24. A spring piece 32 is connected to the movable plate 31 near the snap-fit ​​plate 24. The spring piece 32 is drivenly connected to the snap-fit ​​plate 24. By welding the serrated plate 23 to both sides of the wire clamp 22, when the wire clamp 22 is installed inside the housing 21, the serrated plate 23 and the snap-fit ​​plate 24 snap together. The serrated plate 23 and the snap-fit ​​plate 24 achieve mechanical engagement through their matching serrations, which helps to improve the anti-slip ability. Since the serrations on both sides of the serrated plate 23 are in opposite directions, the serrated plate 23 can be clamped in both directions, preventing the wire clamp 22 from being clamped in one or both directions due to external force. The sliding mechanism enhances the stability of the connection between the guy wire and the clamp 22, solving the problem of wedge block slippage and tension attenuation when the guy wire is subjected to reverse vibration, alternating load, or long-term fatigue. This helps reduce the loosening of the traditional clamp 22 due to vibration and improves the stability of the pole. Simultaneously, the welded connection method fixes the spring piece 32 between the snap-fit ​​plate 24 and the movable plate 31, connecting the snap-fit ​​plate 24 inside the movable plate 31. When the snap-fit ​​plate 24 and the serrated plate 23 experience prolonged use and wear, gaps may appear between them. At this time, the spring piece 32 uses its own elasticity to push the snap-fit ​​plate 24 and the serrated plate 23 back into contact, ensuring accurate engagement and stability of the connection between the serrated plate 23 and the snap-fit ​​plate 24.

[0039] Furthermore, such as Figures 3-6As shown, a slider 25 is connected to the side of the serrated plate 23 near the outer shell 21. The serrated plate 23 is slidably connected to the outer shell 21 through the slider 25. By welding the slider 25 onto the serrated plate 23 and opening a groove on the outer shell 21 that matches the slider 25, the wire clamp 22 slides along the groove on the outer shell 21 through the slider 25. The slider 25 and the groove cooperate to limit the movement path of the wire clamp 22 and reduce the friction between the wire clamp 22 and the outer shell 21, ensuring the movement of the wire clamp 22 inside the outer shell 21, so that the wire clamp 22 drives the pull wire body 1 to adjust the tightness.

[0040] Furthermore, such as Figures 1-2 As shown, a pull rod 27 is provided on the side of the outer casing 21 away from the pull rod body 1. An annular connector 26 connects the pull rod 27 and the outer casing 21. The connection between the pull rod 27 and the outer casing 21 is achieved by welding the annular connector 26 to the outer casing 21 and the pull rod 27. Since the bottom of the pull rod 27 is buried in the ground at an incline, the angle between the outer casing 21 and the pole is 45 degrees, which helps to improve the stability of the pole.

[0041] Furthermore, such as Figure 5 As shown, a snap-fit ​​block 33 is connected to the side of the snap-fit ​​plate 24 near the movable plate 31. The snap-fit ​​plate 24 snaps into the movable plate 31 through the snap-fit ​​block 33. By opening a snap-fit ​​groove on the movable plate 31 that matches the snap-fit ​​block 33, the snap-fit ​​plate 24 slides inside the snap-fit ​​groove through the snap-fit ​​block 33, and prevents the snap-fit ​​plate 24 from separating from the movable plate 31.

[0042] Furthermore, such as Figure 6 As shown, a threaded post 28 is rotatably mounted on the side of the outer casing 21 near the movable plate 31. The threaded post 28 is threadedly connected to the movable plate 31, and the movable plate 31 is slidably connected to the outer casing 21 through the threaded post 28. By opening a sliding groove on the outer casing 21, the threaded post 28 is slidably connected to the outer casing 21. When the threaded post 28 rotates, it drives the movable plate 31 to slide on the outer casing 21 through the automatic thread groove. The movable plate 31 and the serrated plate 23 cooperate to adjust the elasticity of the spring 32, which facilitates the adjustment of the serrated plate 23 and the snap-fit ​​plate 24, and helps to improve the adjustment and fixation of the wire clamp 22 inside the outer casing 21.

[0043] Furthermore, such as Figure 6 As shown, a nut 29 is connected to one end of the threaded post 28 near the movable plate 31. By installing the nut 29 on the threaded post 28 near the outer side of the movable plate 31, the nut 29 fixes the movable plate 31 to the outer shell 21, causing the movable plate 31 to compress the spring 32 and press the snap-fit ​​plate 24 to snap into the serrated plate 23, which helps to improve the stability of the connection between the outer shell 21 and the wire clamp 22.

[0044] Furthermore, such as Figure 5As shown, an anti-slip coating 34 is provided on the side of the movable plate 31 near the outer shell 21. By spraying the anti-slip coating 34 onto the movable plate 31, the anti-slip coating 34 increases the friction between the movable plate 31 and the outer shell 21. The anti-slip coating 34 and the nut 29 work together to strengthen the connection between the movable plate 31 and the outer shell 21, thereby improving the stability of the connection between the movable plate 31 and the outer shell 21.

[0045] Working principle: such as Figures 1-6 As shown, first, the bottom of the pull rod 27 is buried in the ground at an angle. The annular connector 26 is welded to the bottom of the housing 21 and installed on the pull rod 27. The end of the pull rod body 1 away from the pole is installed inside the clamp 22. Then, the threaded post 28 is rotated using an external tool. The threaded post 28 drives the movable plate 31 to move outward from the housing 21 through its own thread groove. At this time, the elasticity of the spring piece 32 inside the movable plate 31 returns to its maximum. The clamp 22 is inserted into the housing 21. When the serrated plate 23 contacts the snap-fit ​​plate 24, it pushes the snap-fit ​​plate 24 to move inward from the movable plate 31. After the clamp 22 moves to the designated position along the groove through the slider 25, the spring piece 32 pushes the snap-fit ​​plate 24 to snap with the serrated plate 23 through its own elasticity. Then, the threaded post 28 is reversed, so that the movable plate 31 moves outward. The internal movement of the shell 21 causes the movable plate 31 to press the spring 32 and the snap-fit ​​plate 24, reducing the elasticity of the spring 32 and causing the serrated plate 23 and the snap-fit ​​plate 24 to mesh with each other. Then, the nut 29 is installed on the threaded post 28, and the nut 29 fixes the movable plate 31 to the shell 21. Since the serrations on both sides of the serrated plate 23 are in opposite directions, the serrated plate 23 can be clamped in both directions, preventing the wire clamp 22 from sliding in one or both directions due to external force, and improving the stability of the connection between the pull wire and the wire clamp 22. When the snap-fit ​​plate 24 and the serrated plate 23 are used for a long time and wear out, gaps will appear between them. At this time, the spring 32 pushes the snap-fit ​​plate 24 and the serrated plate 23 to re-fit through its own elasticity, ensuring that the snap-fit ​​plate 24 and the serrated plate 23 are accurately meshed together, and ensuring the stability of the connection between the serrated plate 23 and the snap-fit ​​plate 24.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
