Description

Technical Field

[0001] The present utility model relates to the technical field of electric power construction tools, and particularly relates to a guy wire bending and threading tool. Background Art

[0002] In the process of traditional electric power line construction, the fixation of the guy wire terminal is usually installed by a clamp, but this process has obvious technical problems and operational inconveniences. The previous manual operation mode requires the construction personnel to first manually bend the relatively hard steel strand (guy wire) into a specific "U" - shaped return bend structure, and then thread it into the slot of the clamp. Due to the high hardness of the steel strand, manual bending is not only difficult, the bending angle is difficult to accurately control, but also extremely labor - intensive. In addition, after inserting the bent steel strand and the tongue plate (wedge - shaped block) into the clamp slot together, it is also necessary to use a hammering method to make it closely fit with the clamp slot wall. This method not only easily damages the anti - corrosion coating on the surface of the clamp, affecting the service life and installation quality of the clamp, but also has high requirements for the operation skills and strength of the construction personnel, increasing the labor intensity of the operation.

[0003] Practical Content

[0004] Aiming at the deficiencies of the prior art, the present utility model provides a guy wire bending and threading tool, the purpose of which is to solve the problems that the steel strand has high hardness, manual bending is not only difficult, the bending angle is difficult to accurately control, but also extremely labor - intensive.

[0005] To achieve the above - mentioned purpose, the present utility model provides the following technical solution: A guy wire bending and threading tool, comprising a bottom plate, a tensioning power device fixed on the bottom plate, a push rod connected to the output end of the tensioning power device, a pull rod hinged to the push rod, and guide shafts on the bottom plate on both sides of the pull rod. The top of the pull rod has a hook for hooking one end of the wedge - shaped block, and a step for abutting against one end of the clamp is provided at the other end of the bottom plate far from the tensioning power device.

[0006] Further, an arc - shaped notch is provided at the top of the push rod.

[0007] Further, rollers are rotatably connected to the guide shafts. An arc - shaped concave surface is provided on the rollers. There are two guide shafts in total on the bottom plate, and a notch is provided on one of the guide shafts.

[0008] Further, one end of a pressing plate is rotatably connected to one of the guide shafts on the bottom plate, and the other end of the pressing plate is snapped into the notch of the other guide shaft.

[0009] Further, a pressing nut for locking the snapped - in pressing plate on the guide shaft is threadedly connected to the guide shaft on one side of the notch.

[0010] Further, pressing rollers are provided at the bottom of the pressing plate.

[0011] Further, two mounting plates are provided at the bottom of the pressing plate, and the pressing roller is rotationally connected between the two mounting plates through a rotating shaft.

[0012] Further, a heightening block is connected to the bottom plate between the two guide shafts by bolts, and the heightening block is of a "U" - shaped structure.

[0013] Further, the arc - shaped concave surface of the roller is used to define the stay wire.

[0014] Compared with the existing technology, the present utility model has the following beneficial effects: (1) Automatic operation: By integrating components such as a tensioning power device, a push rod, a pull rod, a hook, and a wedge block, the automatic bending and threading process of the stay wire is realized, getting rid of the high dependence on manpower and technical proficiency in traditional manual operations, significantly reducing the labor intensity of construction workers, and improving work efficiency.

(3) Wide applicability: Through the design of an adjustable tensioning power device and pressing rollers, this tool can adapt to different specifications and types of wire clamps, meeting the requirements of stay wire bending and threading in different application scenarios, and improving the versatility of the tool. (4) Protecting the wire clamp and the anti - corrosion layer: Compared with the traditional manual knocking method, this tool mechanically pushes the stay wire into the wire clamp, avoiding possible damage to the wire clamp and the anti - corrosion layer during the knocking process, extending the service life of the wire clamp, and ensuring the overall safety performance of the power line. (5) Simple and fast operation: The entire stay wire bending and threading process is divided into two clear steps, each step has detailed guidance, the operation is simple and easy to perform, and even non - professional technical personnel can quickly master it, which is beneficial to shortening the construction period and reducing the probability of operation errors.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The present utility model will be further described in detail below in conjunction with the embodiments and the drawings.

[0020] As Figure 1 shown, a wire-pulling bending and threading tool includes a bottom plate 1, a tensioning power device 2 fixed on the bottom plate 1, a push rod 3 connected to the output end of the tensioning power device 2, a pull rod 4 hinged to the push rod 3, and guide shafts 5 on the bottom plate 1 on both sides of the pull rod 4. The top of the pull rod 4 has a hook 7 for hooking a wedge block 6. A step 8 for abutting against one end of a wire clamp 19 is provided at the other end of the bottom plate 1 away from the tensioning power device 2. The tool of the present application realizes the precise bending and threading functions of the steel strand through components such as the bottom plate 1, the tensioning power device 2, the push rod 3, the pull rod 4, the guide shafts 5, and the hook 7. The design of the step 8 on the bottom plate 1 ensures the stable positioning of the end of the wire clamp 19 during the bending and threading processes, effectively preventing the wire clamp 19 from sliding or misaligning, and improving the accuracy and safety of the overall operation.

[0021] Among them, the tensioning power device 2 can adopt forms such as an electric cylinder, an oil cylinder, or a pneumatic cylinder.

[0022] Among them, an arc-shaped notch 9 is provided at the top of the push rod 3. The top of the push rod 3 mainly abuts against the wedge block 6 and the wire 18. By providing the arc-shaped notch 9, the mechanical transmission effect between the push rod 3, the wire 18, the wedge block 6, and other components is enhanced, enabling the push rod 3 to better conform to the pushing and pulling trajectories when performing the tensioning and pushing actions, avoiding tool damage or wire 18 damage caused by stress concentration, and further ensuring the smoothness of the bending of the wire 18.

[0023] Among them, a roller 10 is rotatably connected to the guide shaft 5. An arc-shaped concave surface 11 is provided on the roller 10. There are two guide shafts 5 in total on the bottom plate 1. A notch 13 is provided on one of the guide shafts 5. The arc-shaped concave surface 11 of the roller 10 is used to define the position of the wire 18, and at the same time, the rolling action of the roller 10 helps the wire 18 pass through the guide shaft 5 smoothly, improving the bending efficiency and bending accuracy.

[0024] Among them, one end of a pressing plate 12 is rotatably connected to one of the guide shafts 5 on the bottom plate 1, and the other end of the pressing plate 12 is snapped into the notch 13 of the other guide shaft 5. A pressing nut 14 for locking the snapped-in pressing plate 12 on the guide shaft 5 is threadedly connected to the guide shaft 5 on one side of the notch 13. The pressing plate 12 adopts a separable design structure. Its main function is to ensure that during the bending process of the wire 18, the pressing plate 12 can effectively press the pull rod 4 that has hooked the wedge block 6, preventing the pull rod 4 from tilting or loosening when subjected to the force of the tensioning power device 2, and maintaining the stability and accuracy of the wire 18 bending operation.

[0025] In addition, a compression nut 14 is threadedly connected to the guide shaft 5 to ensure that the pressing force of the pressing plate 12 on the pull rod 4 in the closed state is firmly maintained; this design enhances the firmness of the connection between the pressing plate 12 and the pull rod 4, so that even when encountering large resistance or impact during the strong tensioning process, the pressing plate 12 will not accidentally break away or become loose, thus ensuring the continuity and consistency of the bending of the wire 18.

[0026] Wherein, a pressing roller 15 is provided at the bottom of the pressing plate 12, and two mounting plates 16 are provided at the bottom of the pressing plate 12. The pressing roller 15 is rotatably connected between the two mounting plates 16 through a rotating shaft; the pressing roller 15 provided at the bottom of the pressing plate 12 ensures that the wedge block 6 receives a uniform and stable pressing force during the bending process by reducing the contact area.

[0027] Wherein, a heightening block 17 is bolted to the bottom plate 1 between the two guide shafts 5, and the heightening block 17 is of a "U" - shaped structure; the main function of the heightening block 17 is to support and position the wedge block 6. As Figure 1 - Figure 2 shown, when using wire clamps 19 of other specifications, the heightening block 17 can be removed, as Figure 3 shown.

[0028] As Figure 1 - Figure 3 shown, the specific working process of the present utility model is as follows:

[0029] Place the wire 18 to be bent between the two guide shafts 5 of the tool, ensuring that the wire 18 is centered; then, press one end of the wedge block 6 against the middle of the wire 18, and at the same time stably hook the other end of the wedge block 6 through the hook 7 at the top of the pull rod 4; subsequently, lock the pressing plate 12 on the guide shaft 5, and use the pressing roller 15 on the pressing plate 12 to firmly press the pull rod 4 to ensure that the hook 7 of the pull rod 4 can reliably hook the wedge block 6; start the tensioning power device 2, and through the linkage of the tensioning power device 2 and the push rod 3, drive the wedge block 6 to move along the tensioning direction, thereby forcing the wire 18 to stretch and pass through the channel formed by the guide shafts 5, and then realizing that the wire 18 is bent into a preset "U" - shaped structure at one time; pre - connect the wire clamps 19 to be installed to both ends of the wire 18 respectively, and then accurately abut one end of the wire clamp 19 against the step 8 provided at one end of the tool bottom plate 1 away from the tensioning power device 2; then, release the fixed state of the pressing plate 12 and lift the pull rod 4; finally, start the tensioning power device 2 again, and manipulate the push rod 3 to push the bent wire 18 and the wedge block 6 as a whole into the wire clamp 19 until the wire 18 and the wedge block 6 are completely embedded in the notch of the wire clamp 19, thus completing the wire threading and assembly process.

[0030] By using the tool and the usage method of the present application, not only can the precise bending and rapid threading of the guy wire 18 be completed at one time, but also the labor intensity is significantly reduced, the work efficiency is improved, and at the same time, the damage to the anti-corrosion layer of the clamp 19 is avoided, ensuring the installation quality, and reflecting the convenience and high efficiency of the tool in practical applications.

[0031] Although the embodiments of the present utility have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility.
