Description

Technical Field

[0001] This utility model relates to the technical field of high-voltage power grids, specifically to a high-strength wedge-shaped wire clamp. Background Technology

[0002] With the progress of the times and the development of science and technology, my country's power industry technology has also flourished, and the construction of various power infrastructures has entered a new development period. At present, most of the cables used on domestic transmission lines are compression-type tension clamps, while wedge-shaped tension clamps are only used in rural power distribution networks. Tension clamps are used to fix cables to withstand the tension between cable lines and to hang cables on strings or towers.

[0003] Utility model patent application No. 207117123U discloses a wedge-shaped insulated tension clamp, comprising a clamp body, a wedge-shaped through hole at one end of the clamp body, a support plate installed within the wedge-shaped through hole, the support plate being a wedge-shaped support plate with a wire groove, a bolt and nut pair at the end of the clamp body away from the wedge-shaped through hole, and a reinforcing protrusion on the outside of the wedge-shaped through hole of the clamp body. Both the clamp body and the support plate of this utility model are made of high-strength aluminum alloy casting, resulting in high product strength and energy efficiency. The use of the wedge-shaped through hole and wedge-shaped support plate prevents conductor slippage during actual operation after installation. The reinforcing protrusion on the outside of the wedge-shaped through hole enhances the strength of the clamp body and extends its service life. The grooves on both sides of the clamp body reduce its weight.

[0004] However, the technical solutions in the above-mentioned utility model still need improvement: when the wedge-shaped wire clamp is hung on the hardware, the bolt on the wedge-shaped wire clamp is directly subjected to force, which causes greater damage to the bolt, and the frictional resistance is small, resulting in poor stability when the wedge-shaped wire clamp is hung on the hardware; when the cable line vibrates and causes the wedge-shaped wire clamp to vibrate, the nut on the bolt will loosen, which will pose a significant safety hazard after a long period of time. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength wedge-shaped clamp that prevents metal cable connections from loosening and improves protection for the extended ends of metal cables.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The device includes a wedge-shaped clamp body, with a connecting seat at one end. The connecting seats are symmetrically arranged, and a through groove is provided on the side of the connecting seat. The through groove is connected to a through slot located inside the connecting seat. A T-shaped fixing tube is inserted into the through slot, and a metal cable is pressed and inserted into the T-shaped fixing tube. A hanging plate is snapped onto the end of the metal cable away from the two T-shaped fixing tubes. A sleeve is fixed to the top of the connecting seat with screws. A limiting member that slides along the axial direction of the sleeve is provided on the side of the sleeve. A metal cable protection member is fixed inside the sleeve.

[0008] Furthermore, an opening is provided on one side of the sleeve.

[0009] The above technical solution facilitates the entry of metal cables and makes installation easier.

[0010] Furthermore, the metal cable protection component includes an elastic sleeve clamp fixed to the inner wall of the sleeve, and the elastic sleeve clamp has a wedge-shaped inlet facing the opening side.

[0011] The above technical solution facilitates the insertion of metal cables and makes installation easier.

[0012] Furthermore, a connecting plate is welded to the bottom of the sleeve, and the connecting plate has several through holes for screws to pass through.

[0013] Using the above technical solution, when installing the sleeve onto the connector, it is fixed with screws. Correspondingly, a threaded hole is provided on the connector. After aligning the threaded hole with the through hole, the screw is screwed in to fix the sleeve.

[0014] Furthermore, a fixing seat is fixed to the side of the sleeve, and a sliding groove is provided inside the fixing seat. A limiting rod is slidably connected inside the sliding groove. A limiting block is integrally provided on the side of the limiting rod. The limiting block slides along the inside of the through groove. A limiting plate is integrally fixed to the end of the limiting rod away from the fixing seat. The limiting plate abuts against the bottom of the T-shaped fixing tube.

[0015] Using the above technical solution, after the T-shaped fixing tube is moved by the swaying of the metal cable, its movement can only be up and down. Therefore, a limiting plate is used to support the bottom of the T-shaped fixing tube to reduce its movement range and further prevent the connection between the metal cable and the T-shaped fixing tube from loosening. Furthermore, a damping rod is fixed to the bottom of the slide groove, and a sliding block that slides inside the slide groove is fixed to the end of the damping rod away from the bottom of the slide groove. The sliding block is welded to the side of the limiting rod.

[0016] Using the above technical solution, the sliding block on the side of the limiting rod abuts against the damping rod, and the damping rod counteracts the force of the movement.

[0017] In summary, the beneficial technical effects of this utility model are as follows:

[0018] 1. An elastic sleeve is adopted. When the metal cable sways, the stress point changes from the point where the metal cable extends out of the T-shaped fixing tube to the point where it contacts the elastic sleeve. Due to the high resilience of the elastic sleeve, it can resist the metal cable. At the contact point of the metal cable, the connection rigidity is reduced, the metal cable is prevented from bending, and the pulling of the T-shaped fixing tube is minimized, thus preventing the connection between the metal cable and the T-shaped fixing tube 5 from becoming loose.

[0019] 2. A limiting plate is used. When the T-shaped fixing tube is moved by the shaking of the metal cable, its movement can only be up and down. Therefore, the limiting plate supports the bottom of the T-shaped fixing tube, reducing its movement range and further preventing the connection between the metal cable and the T-shaped fixing tube from loosening. 3. A connecting plate is used. When installing the sleeve onto the connecting seat, it is fixed with screws. Correspondingly, threaded holes are set on the connecting seat. After aligning the threaded holes with the through holes, the screws are screwed in to fix the sleeve. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] 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.

[0027] Please see Figure 1-3 The present invention provides a technical solution comprising: a wedge-shaped clamp body 1, a connecting seat 2 at the end of the wedge-shaped clamp body 1, the connecting seats 2 being symmetrically arranged, a through groove 3 on the side of the connecting seat 2, the through groove 3 being connected to a through groove 4, the through groove 4 being located inside the connecting seat 2, a T-shaped fixing tube 5 being inserted into the through groove, a metal cable 6 being pressed and inserted into the T-shaped fixing tube 5, a hanging plate 7 being snapped onto the end of the metal cable 6 away from the two T-shaped fixing tubes 5, a sleeve 8 being screwed to the top of the connecting seat 2, a limiting member being provided on the side of the sleeve 8 for sliding along the axial direction of the sleeve 8, and a protective member for the metal cable 6 being fixed inside the sleeve 8.

[0028] In this embodiment, an opening 9 is provided on one side of the sleeve 8 to facilitate installation with the sleeve 8. A connecting plate 12 is welded to the bottom of the sleeve 8, and the connecting plate 12 is provided with a plurality of through holes 13 for screws to pass through.

[0029] Meanwhile, the protective component of the metal cable 6 includes an elastic sleeve 10 fixed on the inner wall of the sleeve 8, and the elastic sleeve 10 is provided with a wedge-shaped inlet 11 facing the opening 9.

[0030] Then, when installing the sleeve 8 onto the connecting seat 2, it is fixed by screws. Correspondingly, a threaded hole is provided on the connecting seat 2. After aligning the threaded hole with the through hole 13, the screw is screwed in to fix the sleeve 8. When the sleeve 8 is fixed, the metal cable 6 enters the inside of the sleeve 8 along the opening 9, and at the same time enters the inside of the elastic sleeve 10 along the wedge-shaped inlet 11. The elastic sleeve 10 is made of polyurethane material with good elasticity, and the inner wall of the elastic sleeve 10 abuts against the surface of the metal cable 6.

[0031] After using the elastic sleeve 10, when the metal cable 6 swings, the point of force changes from where the metal cable 6 extends out of the T-shaped fixing tube 5 to where it contacts the elastic sleeve 10. As a result, due to the high resilience of the elastic sleeve 10, it can resist the metal cable 6. At the contact point of the metal cable 6, the connection rigidity is reduced, the metal cable 6 is prevented from bending, and the pulling on the T-shaped fixing tube 5 is minimized, thus preventing the connection between the metal cable 6 and the T-shaped fixing tube 5 from becoming loose.

[0032] Meanwhile, a fixing seat 14 is fixed on the side of the sleeve 8. The fixing seat 14 has a sliding groove 15 inside. A limiting rod 16 is slidably connected inside the sliding groove 15. A limiting block 17 is integrally provided on the side of the limiting rod 16. The limiting block 17 slides inside the through groove 3. A limiting plate 18 is integrally fixed at the end of the limiting rod 16 away from the fixing seat 14. The limiting plate 18 abuts against the bottom of the T-shaped fixing tube 5.

[0033] A damping rod 19 is fixed to the bottom of the slide groove 15. A sliding block 20, which slides inside the slide groove 15, is fixed to the end of the damping rod 19 away from the bottom of the slide groove 15. The sliding block 20 is welded to the side of the limiting rod 16. Therefore, when the T-shaped fixing tube 5 is moved by the swaying of the metal cable 6, its movement is limited to up and down. Thus, a limiting plate 18 is used to support the bottom of the T-shaped fixing tube 5, reducing its range of motion and further preventing the connection between the metal cable 6 and the T-shaped fixing tube 5 from loosening. Specifically, when the limiting plate 18 moves downwards, it causes the limiting rod 16 to move downwards, causing the sliding block 20 on the side of the limiting rod 16 to abut against the damping rod 19, which counteracts the force of the movement. Simultaneously, a limiting block 17 is provided on the side of the limiting rod 16. The limiting block 17 slides inside the through groove 3, further improving the stability of the limiting rod 16 during movement and enhancing the overall installation stability of the connecting seat 2.

[0034] The working principle of this utility model is as follows: A sleeve 8 is installed at the connecting seat 2 of the wedge-shaped clamp body 1. The sleeve 8 is fixed to the connecting seat 2 with screws. The metal cable is placed inside the elastic sleeve 10 inside the sleeve 8. When the metal cable 6 shakes, the force point changes from the point where the metal cable 6 extends out of the T-shaped fixing tube 5 to the point where it contacts the elastic sleeve 10. Due to the high resilience of the elastic sleeve 10, it can resist the metal cable 6. At the contact point of the metal cable 6, the connection rigidity is reduced, and the metal cable 6 is prevented from bending. At the same time, the limiting plate 18 is used to support the bottom of the T-shaped fixing tube 5, reducing its movement range and further preventing the connection between the metal cable 6 and the T-shaped fixing tube 5 from loosening.
