Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of power installation, and more particularly, to a power guy wire fitting. Background Art

[0002] In the power transmission and distribution system, utility poles are important infrastructure for supporting overhead power lines. Their stability is directly related to the safety and stability of power supply. Power guy wire fittings are key components to ensure the stability of utility poles. By connecting the utility pole and the guy wire, the unbalanced load borne by the utility pole is transferred to the ground, thereby preventing the utility pole from tilting or toppling and affecting power transmission. Existing power guy wire fittings mainly include wedge-type wire clamps, UT-type wire clamps, and U-type clamp heads. Most of their fixing methods use simple planar clamping methods. In actual fixing, since guy wires mostly use steel stranded wires, the contact between existing power guy wire fittings and the guy wire is only at local points or small areas. This leads to the fact that when facing complex natural environments for a long time, such as continuous shaking caused by strong winds, water flow impact brought by heavy rains, and external forces such as mechanical vibrations, the friction between the wire clamp and the guy wire is not enough to maintain a stable connection, and loosening is very likely to occur. Once the wire clamp loosens, the tension of the guy wire will become unstable, the force balance of the utility pole is broken, seriously threatening the stability of the utility pole, and even possibly causing major safety accidents such as the collapse of the utility pole. Summary of the Invention

[0014] The beneficial effects of the present disclosure are: 1. In the present disclosure, through the cooperative design of the wire-pulling slide rod and the one-way limiting part, the one-way progressive traction of the wire-pulling assembly is realized. Then, with the fixing effect of the traction positioning assembly, the traction stroke of the steel strand can be accurately controlled, avoiding the backstepping phenomenon. The synergistic effect of the trapezoidal limiting block and the limiting spring can ensure the stability and reliability of the traction process, and the single traction amount can be accurately adjusted through the spacing of the limiting grooves; 2. In the present disclosure, by setting the wire-clamping positioning assembly with worm and worm gear transmission, the symmetrically distributed wire-clamping screws are driven to move synchronously by the wire-clamping worm. Cooperating with the I-shaped wire-fixing clamp and the wire-winding positioning rod, a three-dimensional clamping structure is formed. This design not only realizes the self-locking fixation of the steel strand, but also can quickly adjust the clamping force through the internal hexagonal wire-clamping power groove, effectively preventing the steel strand from slipping. Before clamping and fixing the steel strand, the multiple steel wires wound at the end of the steel strand can be untwisted and dispersed. The dispersed steel wires are arranged through the corresponding wire-dividing through holes in the wire-dividing positioning cover through the wire-pulling tube. Then, when the I-shaped wire-fixing clamp and the wire-winding positioning rod compress the steel wires and approach the wire-winding movable rod, after some steel wires are located on one side of the wire-winding movable rod, by rotating the internal hexagonal wire-winding power groove on one side of the convex wire-winding block, the wire-winding movable rod is driven to move. The movement of the wire-winding movable rod can drive the steel wires between the winding movable rod and the winding positioning rod to bend. Through the cooperation of the wire-winding positioning bolt and the positioning thread groove, the angle of the wire-winding rod can be quickly locked. Then, with the movement of the I-shaped wire-fixing clamp and the wire-winding positioning rod, the steel strand with some bent steel wires is fixed. After some steel wires are bent and then pressed, the contact area and friction force between the steel strand and the I-shaped wire-fixing clamp, the wire-winding positioning rod and the wire-winding movable rod can be further increased, improving the stability of the wire-pulling; 3. In the present disclosure, by setting the wire-passing assembly, with the cooperation of the spring shock absorber and the arc friction block, a multi-directional buffer system is formed, effectively absorbing the vibration energy during the traction of the steel strand, reducing the risk of metal fatigue, and prolonging the service life of the wire; 4. In the present disclosure, by setting the traction positioning assembly and the wire-pulling ring, the position of the wire-pulling frame can be quickly connected and positioned through the traction positioning ring. By setting the wire-pulling ring, not only can the wire-pulling ring be pulled from a distance to traction one end of the steel strand to prevent the steel strand from loosening, but also the wire-pulling ring can be connected to the connecting device together with the traction positioning ring to form a double insurance mechanism, so that when the wire-pulling slider retracts on the wire-pulling slide rod, the wire-pulling slider can be tractioned a second time to prevent the steel strand from loosening.

[0023] Additionally, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0024] As Figures 1 to 6 shown, it shows a kind of electric wire-pulling fitting in an embodiment of this disclosure, including a wire-pulling frame 1, two wire-clamping and positioning assemblies 002, a wire-winding rod 3, a traction and positioning assembly 004, and a wire-passing assembly 005.

[0025] Among them, two wire-pulling slide bars 2 are detachably arranged in parallel on the wire-pulling frame 1, and a wire-pulling assembly 001 that moves unidirectionally is slidably arranged between the two wire-pulling slide bars 2 for pulling the steel strand. By disassembling the wire-pulling slide bar 2, the position of the wire-pulling assembly 001 can be reset and adjusted.

[0026] As described above, the wire-pulling assembly 001 includes two wire-pulling sliders 5 and a wire-pulling tube 7. The wire-pulling sliders 5 correspond to the wire-pulling slide bars 2 one by one. The wire-pulling sliders 5 are slidably arranged on the wire-pulling slide bars 2. A plurality of limiting grooves 6 are equidistantly formed on the wire-pulling slide bars 2. A unidirectional limiting part adapted to the limiting grooves 6 is arranged in the wire-pulling sliders 5, so that the wire-pulling sliders 5 move on the wire-pulling slide bars 2 in the direction of the wire-passing assembly 005 towards the traction positioning assembly 004. The wire-pulling tube 7 is arranged between the two wire-pulling sliders 5. A wire-splitting positioning cover 8 is arranged on one side of the wire-pulling tube 7 close to the traction positioning assembly 004. A winding positioning assembly 003 is arranged on the wire-splitting positioning cover 8. A wire-clamping positioning assembly 002 is arranged through the wire-pulling tube 7.

[0027] Among them, the unidirectional limiting part includes a trapezoidal limiting block 9. A unidirectional limiting groove is formed on the wire-pulling slider 5. The trapezoidal limiting block 9 is slidably arranged in the unidirectional limiting groove. One end of the trapezoidal limiting block 9 is adapted to the limiting groove 6. A plurality of limiting springs 10 are arranged between the other end of the trapezoidal limiting block 9 and the wire-pulling slider 5 for extruding the trapezoidal limiting block 9 into the limiting groove 6.

[0028] Specifically, when adjusting the position of the wire-pulling tube 7, the wire-pulling slider 5 is slid on the wire-pulling slide bar 2. As the wire-pulling slider 5 moves, under the compression deformation of the limiting spring 10, the trapezoidal limiting block 9 is toggled in the corresponding limiting groove 6. Due to the specific shapes of the trapezoidal limiting block 9 and the limiting groove 6, the limiting slider can only move unidirectionally on the limiting slide bar. The single traction amount of the trapezoidal limiting block 9 can be accurately adjusted through the distance between the limiting grooves 6.

[0029] As described above, both of the two wire clamping and positioning components 002 have a self-locking function and are symmetrically arranged on the wire pulling component 001 for fixing the steel strand. The wire clamping and positioning component 002 includes a wire clamping box 11, two wire clamping limiting tubes 12, two wire clamping nuts 13, two wire clamping screws 14, two wire clamping worm wheels 15, a wire clamping worm 16, a T-shaped wire fixing clamp 17 and a plurality of wire winding positioning rods 18. The wire clamping box 11 is arranged on the wire pulling tube 7. One end of the wire clamping limiting tube 12 penetrates and communicates with the wire pulling tube 7, and the other end of the wire clamping limiting tube 12 is located inside the wire clamping box 11. The wire clamping nuts 13 correspond to the wire clamping limiting tubes 12 one by one. The wire clamping nuts 13 are rotatably arranged on one side of the wire clamping limiting tubes 12 located inside the wire clamping box 11. The two wire clamping screws 14 are symmetrically arranged. The wire clamping screws 14 correspond to the wire clamping nuts 13 one by one. The wire clamping screws 14 are threadedly connected inside the wire clamping nuts 13. One end of the wire clamping screw 14 penetrates the wire clamping limiting tube 12 into the wire pulling tube 7. The wire clamping worm wheels 15 correspond to the wire clamping nuts 13 one by one. The wire clamping worm wheels 15 are sleeved on the wire clamping nuts 13. The wire clamping worm 16 penetrates and is rotatably arranged inside the wire clamping box 11. The wire clamping worm 16 is located between the two wire clamping worm wheels 15 and meshes with the two wire clamping worm wheels 15. One end of the wire clamping worm 16 is provided with an internal hexagonal wire clamping power groove. The T-shaped wire fixing clamp 17 is arranged on the two wire clamping screws 14. The T-shaped wire fixing clamp 17 is located inside the wire pulling tube 7. The plurality of wire winding positioning rods 18 are equidistantly arranged on the T-shaped wire fixing clamp 17. The wire winding positioning rods 18 are arranged in a staggered manner with the wire winding movable rods 4.

[0030] Specifically, when clamping and fixing the steel strand, rotating the internal hexagonal wire clamping power groove can drive the wire clamping worm 16 to rotate. The rotation of the wire clamping worm 16 drives the engaged wire clamping worm wheels 15 to rotate. The rotation of the wire clamping worm wheels 15 can drive the wire clamping nuts 13 connected thereto to rotate. By setting the thread directions on the two wire clamping screws 14, the rotation of the wire clamping nuts 13 can drive the wire clamping screws 14 to perform linear motion inside the wire clamping limiting tubes 12. The rotation of the wire clamping screws 14 can drive the T-shaped wire fixing clamp 17 and the wire winding positioning rods 18 to move. Through the relative movement of the two T-shaped wire fixing clamps 17, the clamping and fixing operation of the steel strand can be carried out.

[0031] As described above, the winding rod 3 is rotationally arranged in the wire pulling assembly 001 through the winding positioning assembly 003. A plurality of winding movable rods 4 are arranged on the winding rod 3. The winding movable rods 4 are located between two wire clamping positioning assemblies 002 in the wire pulling assembly 001 and are used for bending the scattered steel strands. The winding positioning assembly 003 includes a convex winding block 19 and a plurality of winding positioning bolts 20. The convex winding block 19 penetrates and is rotationally arranged on the side of the wire splitting positioning cover 8 away from the wire pulling pipe 7. An internal hexagonal winding power groove is formed on the side of the convex winding block 19 away from the wire pulling pipe 7. The winding rod 3 is arranged on the convex winding block 19. The plurality of winding positioning bolts 20 are evenly distributed at equal angles on the wire splitting positioning cover 8. The winding positioning bolts 20 penetrate and are threadedly connected to the wire splitting positioning cover 8. A plurality of positioning threaded grooves adapted to the winding positioning bolts 20 are formed on the convex winding block 19 for fixing the convex winding block 19.

[0032] Specifically, by rotating the internal hexagonal winding power groove, the convex winding block 19 can be driven to rotate. By the rotation of the convex winding block 19, the winding rod 3 and the winding movable rods 4 can be driven to rotate. By tightening the winding positioning bolts 20, the position of the convex winding block 19 can be positioned.

[0033] It should be supplemented that a plurality of wire splitting through holes 27 are equidistantly formed on the wire positioning cover for passing through the scattered steel strands.

[0034] By arranging the wire clamping positioning assembly 002 with worm and worm gear transmission, the symmetrically distributed wire clamping screws 14 are driven by the wire clamping worm 16 to move synchronously. Cooperating with the I-shaped wire fixing clamp 17 and the winding positioning rod 18, a three-dimensional clamping structure is formed. This design not only realizes the self-locking fixation of the steel strands, but also can quickly adjust the clamping force through the internal hexagonal wire clamping power groove, effectively preventing the steel strands from slipping. And before clamping and fixing the steel strands, the multiple steel wires wound at the end of the steel strands can be untwisted and scattered. The scattered steel wires are arranged through the corresponding wire splitting through holes 27 in the wire splitting positioning cover 8 from the wire pulling pipe 7. Then, when the I-shaped wire fixing clamp 17 and the winding positioning rod 18 compress the steel wires and approach the winding movable rod 4, after part of the steel wires are located on one side of the winding movable rod 4, by rotating the internal hexagonal winding power groove on one side of the convex winding block 19, the winding movable rod 4 is driven to move. By the movement of the winding movable rod 4, the steel wires between the winding movable rod and the winding positioning rod can be bent. Through the cooperation of the winding positioning bolts 20 and the positioning threaded grooves, the angle of the winding rod 3 can be quickly locked. Then, by the movement of the I-shaped wire fixing clamp 17 and the winding positioning rod 18, the steel strands with part of the steel wires bent are fixed. After part of the steel wires are bent, and then pressed, the contact area and friction force between the steel strands and the I-shaped wire fixing clamp 17, the winding positioning rod 18 and the winding movable rod 4 can be further increased, improving the stability of the wire pulling.

[0035] As described above, the traction positioning assembly 004 is provided on the wire drawing frame 1. The traction positioning assembly 004 is located on one side of the moving direction of the wire drawing assembly 001 and is used to position the wire drawing frame 1. The traction positioning assembly 004 includes a traction frame 21 and a traction positioning ring 22. The traction frame 21 is provided on the wire drawing frame 1, and the traction positioning ring 22 is provided on the side of the traction frame 21 away from the wire drawing frame 1.

[0036] Specifically, by providing the traction frame 21 and the wire drawing frame 1, the wire drawing assembly 001 and the wire clamping and positioning assembly 002 can be effectively protected from being impacted by relatively large external objects. By providing the traction positioning ring 22 on one side of the traction frame 21, it is convenient for the traction frame 21 to be quickly connected to external cables.

[0037] It should be supplemented that a wire drawing rope 28 is provided on one side of each wire drawing slider 5 close to the traction positioning assembly 004. One end of the wire drawing rope 28 passes through the traction frame 21 and is provided with a wire drawing ring 29. By providing the wire drawing ring 29, not only can the wire drawing ring 29 be pulled from a distance to traction one end of the steel strand to prevent the steel strand from loosening, but also the wire drawing ring 29 can be connected to the connection device together with the traction positioning ring 22 to form a double insurance mechanism, so that when the wire drawing slider 5 retracts on the wire drawing slide rod 2, the wire drawing slider 5 can be secondarily tractioned to prevent the steel strand from loosening.

[0038] As described above, the wire threading assembly 005 has a buffer and shock absorption function. The wire threading assembly 005 is provided on the side of the wire drawing frame 1 away from the traction positioning assembly 004 and is used to limit the steel strand. The wire threading assembly 005 includes a wire threading frame 23, a wire threading cylinder 24, and a plurality of spring shock absorption parts. The wire threading frame 23 is provided on the wire drawing frame 1, the wire threading cylinder 24 is provided on the wire threading frame 23, and the plurality of spring shock absorption parts are staggered and arranged around the wire threading cylinder 24 for shock absorption of the steel strand.

[0039] Among them, the spring shock absorption part includes a spring shock absorber 25 and an arc friction block 26. The spring shock absorber 25 is provided in the wire threading cylinder 24, and the arc friction block 26 is provided at the end of the spring shock absorber 25 away from the wire threading cylinder 24 for contacting the steel strand.

[0040] Specifically, the spring shock absorber 25 is a shock absorption device well-known to those skilled in the art, and its specific structure is not the main innovation point of this application. By providing a plurality of spring shock absorbers 25, through the cooperation of the spring shock absorber 25 and the arc friction block 26, the vibration and friction damage of the steel strand during the wire threading process can be effectively reduced. When the steel strand is impacted by external forces or vibrates during operation, the spring shock absorption part can absorb part of the energy, protect the steel strand and the fittings themselves, extend their service life, and at the same time reduce the risk of failures caused by the wear of the steel strand.

Although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present disclosure can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present disclosure, and all of them should be covered by the scope of the claims of the present disclosure.
