Description

Technical Field

[0001] The present invention relates to the technical field of wire tie fittings, in particular to a wire tie fitting for an electric tower. Background Art

[0002] Tower guy wire hardware is an essential component in wind turbine tower construction. They are specifically designed to connect, secure, adjust, and protect the guy wires, ensuring the overall stability and safety of the tower. These metal components play a vital role in power facilities. Their core function is to securely fasten, precisely adjust, and efficiently connect the tower guy wires. These features collectively maintain the stability of the tower structure, enabling it to withstand the intense impact of extreme natural conditions such as strong winds, effectively preventing safety accidents such as tower tilting or collapse, and thus ensuring the safe operation of power facilities.

[0003] In the existing technology, the wire pulling material used in wire pulling hardware is mainly galvanized steel stranded wire, which has good corrosion resistance and strength, and can meet the high requirements of power facilities for wire pulling materials. There are many types of wire pulling hardware. Among them, UT-shaped wire clamps, as an adjustable wire clamp, occupy an important position in wire pulling hardware. Through the UT-shaped wire clamp, the operator can easily adjust the tightness of the wire pulling body to adapt to different working environments and needs. At the same time, the wire clamp also uses a wedge running through the wire pulling ring to fix the wire pulling body to ensure the stability and reliability of the wire pulling.

[0004] However, although the wire pulling hardware in the existing technology has met the needs of power facilities to a certain extent, there are still some shortcomings, especially in the design of the wedge. Most of the wedges in the existing technology are straight-plate-shaped. This design method only relies on the wedge to contact the wire pulling body in the wire pulling hole for fixation. Under the long-term blowing of wind, it is easy to cause the wire pulling body to swing and slip, and the fixing effect of the wire pulling body is not strong enough. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem that most of the wedges in the prior art are straight-plate shaped. This design method only relies on the wedge to contact the wire body in the wire hole to fix it. When it is blown by the wind for a long time, it is easy to cause the wire body to swing and slip, and the fixing effect of the wire body is not strong enough.

[0006] To achieve the above-mentioned object, the present invention adopts the following technical solution: a power tower wire pulling hardware: comprising a hardware body, the hardware body including a U-shaped bolt, the outer periphery of the U-shaped bolt is slidably connected to a wire pulling block, and the wire pulling block is connected to the wedge block through a wire pulling channel provided inside, and further comprising: a wire pulling assembly and a tightening assembly installed inside the wire pulling channel; The wire pulling assembly includes a fixed column fixedly connected to the inner wall of the wire pulling channel, and the outer periphery of the fixed column is slidably connected to a sliding sleeve; The clamping assembly includes several sliding grooves opened on the sliding sleeve and the side of the wire pulling block. Several clamping blocks are connected to the inside of the sliding sleeve. The two sides of the clamping block are slidably connected to the sliding grooves through connecting rods and extension rods, and one end of the connecting rod passes through the sliding groove and is connected to the limit plate. One side of the wire pulling block is connected to the extension rod through a rotating part. The rotating part drives the extension rod to slide in the sliding groove, so that the clamping block expands outward, and the pull wire is pressed to contact the inner wall of the wire pulling channel, thereby increasing the contact area.

[0007] This technical solution uses a rotating part to drive the extension rod to slide in the sliding groove, causing multiple clamping blocks to expand outward synchronously, radially expanding the pull wire and pressing it tightly against the inner wall of the pull wire channel, significantly increasing the contact area between the pull wire and the channel and improving friction. The clamping block achieves multi-directional linkage expansion through the sliding mechanism of the connecting rod and the extension rod, and can adapt to pull wires of different diameters to ensure that it always fully fits the inner wall of the channel after expansion, avoiding local stress concentration. It solves the problem of loose fixation of straight wedge blocks due to only one-way resistance. It is especially suitable for scenes such as wind power towers that are subject to long-term wind vibration, and fundamentally improves the anti-slip ability of the pull wire.

[0008] As a further description of the above technical solution: The rotating part includes an embedded groove opened on one side of the wire pulling block, the inner wall of the embedded groove is slidably connected to a rotating plate, one side of the rotating plate is connected to a toggle plate, the side of the toggle plate is penetrated by a limiting groove for the extension rod to contact and slide, and the outer periphery of the toggle plate is connected to a plurality of clamping blocks.

[0009] As a further description of the above technical solution: A fixing part is connected between the outer periphery of the wire pulling block and the clamping block. The fixing part includes a mounting plate connected to the outer periphery of the wire pulling block. Several mounting brackets are fixedly connected to the inner wall of the mounting plate, and positioning columns are connected between the inner walls of the mounting brackets. The positioning columns are connected to the abutment blocks through the rotation of the torsion springs on the outer periphery, and the abutment blocks are in contact with the clamping block.

[0010] As a further description of the above technical solution: A release member is connected between the rotating plate and the toggle plate. The release member includes a plurality of telescopic slots opened inside the rotating plate. A telescopic rod slidably connected to the telescopic slot is connected to one side of the toggle plate, and a tension spring is connected between the telescopic rod and the telescopic slot.

[0011] As a further description of the above technical solution: The interior of the wire pulling block is connected with an adjustment component, which includes a telescopic spring and a pressure spring arranged on the outer periphery of the fixed column. The side of the sliding sleeve is connected with a push rod which is slidably connected to the wire pulling block. The push rod extends out of the wire pulling block and is connected to the push plate. The inner wall of the wire pulling channel is connected with two symmetrical oblique blocks.

[0012] As a further description of the above technical solution: The side surface of the inclined block is provided with an inclined surface facing the pressure spring.

[0013] As a further description of the above technical solution: The side of the sliding sleeve is connected to a clamping assembly, which includes a movable groove opened on the side of the sliding sleeve. The inner wall of the movable groove is slidably connected to a gear plate. The top of the gear plate is connected to a clamping block in contact with the pull wire. The gear plate and the extension rod are connected by a transmission member.

[0014] As a further description of the above technical solution: The transmission member includes a gear bar fixedly connected to the outer periphery of the extension rod and a mounting rod fixedly connected to the side of the sliding sleeve plate. The outer periphery of the mounting rod is rotatably connected to a rotating gear, and the rotating gear is meshed with the gear bar and the gear plate.

[0015] As a further description of the above technical solution: The hardware body also includes a fixing ring installed on the top of the pile body and connected to the U-bolt, and the U-bolt and the wire block are limited by fixing screws.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: By means of the provided tightening assembly, the toggle plate is rotated to drive the rotating plate and the extension rod to slide in the limiting groove and the sliding groove, so that the tightening block is extended outward and pushes the pull wire to fit closely against the inner wall of the pull wire channel, thereby increasing the contact area and friction and improving the fixing effect. At the same time, the rotation of the toggle plate also drives the clamping block to press the abutting block and squeeze the torsion spring. When the clamping block is disengaged from the abutting block, the torsion spring rebounds to reset the abutting block and abut against the clamping block again to prevent the toggle plate from deflecting, thereby ensuring the stability of the abutment block fixing the pull wire. When the fixation needs to be released, the toggle plate is pulled to separate the clamping block from the abutting block, and the toggle plate is rotated to reset the extension rod to separate the pull wire from the pull wire channel, so as to facilitate the adjustment of the fixing degree. By setting the adjustment component and the clamping component, in order to improve the fixing effect, the push plate can be pressed before installation to push the sliding sleeve to slide and stretch the telescopic spring and squeeze the pressure spring, so that the pull wire can smoothly pass through the space between the oblique block and the wedge block into the pull wire channel. After passing through, it is secured with a fixing clamp and the push plate is released. The spring restoring force makes the pull wire close to the angle space between the oblique block and the wedge block, increasing the contact area, which complements the tightening of the pull wire by the clamping block, further enhancing the fixing effect. At the same time, the sliding of the extension rod drives the gear bar to move, drives the rotating gear to rotate, causes the gear plate to move the clamping block to clamp the pull wire, further improving the fixing effect.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0029] like Figures 1-10 As shown, the present invention provides an electric tower wire pulling hardware: it includes a hardware body 10, the hardware body 10 includes a U-shaped bolt 11, the outer periphery of the U-shaped bolt 11 is slidably connected to a wire pulling block 13, and the wire pulling block 13 is connected to the wedge block 15 through a wire pulling channel 131 opened inside, the hardware body 10 also includes a fixing ring 12 installed on the top of the pile body and connected to the U-shaped bolt 11, the U-shaped bolt 11 and the wire pulling block 13 are limited by a fixing screw 14, and also includes: a wire pulling assembly 20 and a tightening assembly 30 installed inside the wire pulling channel 131.

[0030] When installing and fixing the wire, the first thing to do is to embed the fixing ring 12 into the top position of the pile body. Then, the U-bolt 11 needs to be smoothly passed through the reserved hole of the fixing ring 12, and then the wire block 13 is placed on the outer surface of the U-bolt 11. In order to ensure the stability and position of the wire block 13, it is necessary to rotate and tighten the fixing screw 14 to achieve effective limitation of the wire block 13. In addition, during the installation of the wire, the operator needs to pass one end of the wire through the wire channel 131 preset inside the wire block 13.

[0031] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 5As shown, the wire pulling assembly 20 includes a fixed column 21 fixedly connected to the inner wall of the wire pulling channel 131, and the outer periphery of the fixed column 21 is slidably connected to a sliding sleeve 22, and the sliding sleeve 22 contacts the inner wall of the wire pulling channel 131, preventing the wire from detaching from the middle area of ​​the sliding sleeve 22 when shaken by external wind.

[0032] After the pull wire passes through the pull wire channel 131, it is guided along the middle area of ​​the sliding sleeve 22, so that the pull wire moves along the middle area of ​​the sliding sleeve 22 and finally passes through the pull wire channel 131. Finally, the pull wire end is bound to the pull wire through a fixing clamp to prevent the pull wire end from detaching.

[0033] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 As shown, the tightening assembly 30 includes a plurality of sliding grooves 31 provided on the side of the sliding sleeve 22 and the wire pulling block 13, and a plurality of tightening blocks 32 are connected to the interior of the sliding sleeve 22. The two sides of the tightening block 32 are slidably connected to the sliding grooves 31 by connecting rods 33 and extension rods 34, and one end of the connecting rod 33 passes through the sliding groove 31 and is connected to the limit plate 331. One side of the wire pulling block 13 is connected to the extension rod 34 through a rotating member. The rotating member includes an embedded groove 35 provided on one side of the wire pulling block 13, and the inner wall of the embedded groove 35 is slidably connected to a rotating plate 351. One side of the rotating plate 351 is connected to a toggle plate 352. 2 is penetrated by a limiting groove 353 for the extension rod 34 to contact and slide, and the outer periphery of the toggle plate 352 is connected to a plurality of clamping blocks 354, and a fixing member is connected between the outer periphery of the pull wire block 13 and the clamping block 354. The fixing member includes a mounting plate 36 connected to the outer periphery of the pull wire block 13, and the inner wall of the mounting plate 36 is fixedly connected to a plurality of mounting brackets 361, and positioning columns 362 are connected between the inner walls of the mounting brackets 361. The positioning columns 362 are rotatably connected to the abutment blocks 364 through the torsion springs 363 on the outer periphery. The abutment blocks 364 are in contact with the clamping blocks 354, and the inner wall of the mounting plate 36 is connected to a welding block that limits the rotation of the abutment blocks 364.

[0034] After completing the binding operation of the pull wire, the pull wire can be fixed by rotating the toggle plate 352. The rotation of the toggle plate 352 will drive the rotating plate 351 to rotate synchronously in the embedded groove 35. At the same time, with the rotation of the toggle plate 352, the extension rod 34 will slide in the limiting groove 353, and at the same time, the extension rod 34 will slide smoothly along the sliding groove 31 opened on the sliding sleeve 22. This movement causes the clamping block 32 to extend outward. At the same time, the connecting rod 33 also moves accordingly in the sliding groove 31. As the clamping block 32 is extended outward, the pull wire mounted on the outer periphery of the clamping block 32 is pushed and stretched out by the clamping block 32, so that the pull wire fits tightly against the inner wall of the pull wire channel 131. This not only increases the contact area between the pull wire and the pull wire channel 131, thereby enhancing the friction and improving the fixing effect of the pull wire, but also the outward adaptability design of the clamping block 32 enables the clamping block 32 to be fixed for pull wires of different sizes.

[0035] At the same time, as the tightening block 32 expands, the pull wire on the outer periphery of the tightening block 32 will expand to a certain extent, and as the tightening block 32 drives the pull wire to expand, the pull wire will move downward a certain distance, so that the pull wire will be tightened to a certain extent while expanding. At the same time, the greater the expansion angle of the pull wire, the smaller the bending force on the pull wire will be, which prevents the pull wire from breaking during long-term use and improves its service life.

[0036] In addition, the rotation of the toggle plate 352 will also drive the clamping block 354 to rotate together. During the rotation process, the clamping block 354 will press the abutment block 364, forcing the abutment block 364 to rotate along the outer periphery of the positioning column 362 and squeeze the torsion spring 363. When the clamping block 354 rotates to disengage from the abutment block 364, the squeezed torsion spring 363 will rebound quickly, driving the abutment block 364 to reset and make close contact with the welding block. At this time, the abutment block 364 will form an abutment state with the clamping block 354 again. This design effectively prevents the toggle plate 352 from rotating and offsetting, thereby ensuring the stability and reliability of the entire fixing device.

[0037] like Figure 6 As shown, a release member is connected between the rotating plate 351 and the toggle plate 352, and the release member includes a plurality of telescopic slots 37 opened inside the rotating plate 351, and a telescopic rod 371 slidably connected to the telescopic slot 37 is connected to one side of the toggle plate 352, and a tension spring 372 is connected between the telescopic rod 371 and the telescopic slot 37.

[0038] At the same time, when it is necessary to release the fixation of the pull wire later, by pulling the toggle plate 352, the toggle plate 352 drives the telescopic rod 371 to slide in the telescopic groove 37, and stretches the tension spring 372. When the toggle plate 352 moves, it drives the clamping block 354 to move synchronously, so that the clamping block 354 gradually disengages from the abutment with the abutment block 364. At this time, the toggle plate 352 can be rotated so that the toggle plate 352 drives the rotating plate 351 to rotate together under the embedded action of the telescopic rod 371, and the extension rod 34 embedded in the limiting groove 353 is rotated and reset, so that the pull wire is disengaged from the contact with the pull wire channel 131, thereby facilitating the adjustment of the fixation degree of the pull wire again.

[0039] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 9 As shown, the interior of the wire pulling block 13 is connected with an adjusting component 40, and the adjusting component 40 includes a telescopic spring 41 and a pressure spring 42 which are sleeved on the outer periphery of the fixed column 21. The elastic force of the pressure spring 42 is greater than that of the telescopic spring 41. The side of the sliding sleeve 22 is connected with a pushing rod 44 which is slidably connected to the wire pulling block 13. The pushing rod 44 extends out of the wire pulling block 13 and is connected with the pushing plate 45. The inner wall of the wire pulling channel 131 is connected with two symmetrical inclined blocks 43, and the side of the inclined block 43 is provided with an inclined surface facing the pressure spring 42.

[0040] In order to improve the fixing effect of the pull wire, before installing the pull wire, a preparatory action can be performed by operating the push plate 45. Specifically, pressing the push plate 45 will drive the push rod 44 to move, and then push the sliding sleeve 22 to slide smoothly along the outer periphery of the fixed column 21. During this process, the sliding sleeve 22 will stretch the telescopic spring 41 and produce an extrusion effect on the pressure spring 42. Subsequently, pull wires of different sizes can smoothly pass through the space formed between the inclined block 43 and the wedge block 15, enter the interior of the pull wire channel 131, and continue to move along the area between the sliding sleeve 22 until it passes through the other end of the pull wire channel 131 and is finally stabilized by the fixing clamp.

[0041] After the pull wire is passed through and fixed, the push plate 45 is released. At this time, since the telescopic spring 41 is in a stretched state and the pressure spring 42 is in an extruded state, the rebound force of the telescopic spring 41 and the pressure spring 42 works together, so that the pull wire that has passed through the pull wire channel 131 will be tightly pressed against the angle space between the inclined block 43 and the wedge block 15. In this way, the pull wire forms a wider contact with the inclined surface of the inclined block 43 and the surface of the wedge block 15, which not only increases the contact area, but also complements the pressing effect of the pressing block 32 on the pull wire, further enhancing the fixing effect of the pull wire.

[0042] In addition, when the guy wire is installed, it is affected by the length of the guy wire. When the length of the guy wire is short, the tightening block 32 cannot expand and tighten the guy wire. In a wind power environment, the wind force is constantly changing. The design of the telescopic spring 41 and the pressure spring 42 in the adjustment component 40 enables the guy wire hardware to automatically adapt to the slight displacement of the guy wire when it is affected by wind force. When the wind force increases, the guy wire may be subjected to tension and try to move. The pressure spring 42 will be further compressed, providing a certain buffer and rebound force to help the guy wire maintain a stable position. This automatic adjustment capability helps to reduce the risk of the guy wire loosening or breaking due to changes in wind force. At the same time, the guy wire is affected by wind force and to a certain extent drives the sliding sleeve 22 to slide on the periphery of the fixed column 21, and produces additional squeezing on the pressure spring 42. Once the wind force weakens or disappears, the pressure spring 42 will rebound quickly, pushing the sliding sleeve 22 and the guy wire to quickly return to the state of contact with the inclined surface of the inclined block 43, increasing the contact between the inclined surface of the inclined block 43 and the guy wire, and improving the guy wire fixing effect.

[0043] When the pull wires of different sizes are blown by the wind, the pressure spring 42 is subjected to different extrusion forces. The large-sized pull wire contacts the inclined surface of the inclined block 43, which will cause the sliding sleeve 22 to move a long distance on the fixed column 21, thereby exerting a large extrusion force on the pressure spring 42, making the rebound force of the pressure spring 42 on the sliding sleeve 22 greater, and making the pull wire fit more tightly with the inclined surface of the inclined block 43. On the contrary, the small-sized pull wire contacts the inclined surface of the inclined block 43, which will cause the sliding sleeve 22 to move a short distance on the fixed column 21, thereby exerting a small extrusion force on the pressure spring 42, making the rebound force of the pressure spring 42 on the sliding sleeve 22 smaller, and making the pull wire fit more tightly with the inclined surface of the inclined block 43.

[0044] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 10 As shown, the side of the sliding sleeve 22 is connected to a clamping assembly 50, and the clamping assembly 50 includes a movable groove 51 opened on the side of the sliding sleeve 22, and the inner wall of the movable groove 51 is slidably connected to a gear plate 55, and the top of the gear plate 55 is connected to a clamping block 56 in contact with the pull wire, and the gear plate 55 is connected to the extension rod 34 through a transmission member, and the transmission member includes a gear bar 52 fixedly connected to the outer periphery of the extension rod 34 and a mounting rod 53 fixedly connected to the side of the sliding sleeve 22, and the outer periphery of the mounting rod 53 is rotatably connected to a rotating gear 54, and the rotating gear 54 is meshed with the gear bar 52 and the gear plate 55.

[0045] As the extension rod 34 slides in the sliding groove 31, the extension rod 34 will drive the gear bar 52 to move together, and drive the rotating gear 54 to rotate on the outer periphery of the mounting rod 53. At the same time, the rotation of the rotating gear 54 drives the gear plate 55 to move in the moving groove 51, so that the clamping block 56 on the top of the gear plate 55 moves relatively and clamps the pull wire. The clamped pull wire will be tightly attached to the surface of the wedge block 15, and cooperate with the abutment of the clamping block 32 and the bevel block 43, which further increases the contact area while increasing the friction force on the pull wire and improving the fixing effect of the pull wire.

[0046] At the same time, the two clamping blocks 56 clamp the wire inside the wire channel 131. Even if the fixing clamp at the end of the wire collapses after long-term use, the clamping of the wire by the two clamping blocks 56 can prevent the wire from being loose, further improving the degree of clamping and fixing of the wire.

[0047] Working principle: When installing and fixing the pull wire, first embed the fixing ring 12 into the top of the pile body, then insert the U-bolt 11 into the fixing ring 12, insert the pull wire block 13 and tighten the limit with the fixing screw 14, then pass the pull wire into the pull wire channel 131, guide it out through the middle area of ​​the sliding sleeve 22, and bind the pull wire end with a fixing clamp.

[0048] The pull wire is fixed by rotating the toggle plate 352. This action drives the rotating plate 351 to rotate, and the extension rod 34 slides in the limiting groove 353 and the sliding groove 31, so that the tightening block 32 is extended outward, pushing the pull wire to fit tightly against the inner wall of the pull wire channel 131, increasing the contact area and friction, and improving the fixing effect. At the same time, the rotation of the toggle plate 352 also drives the clamping block 354 to rotate, pressing the abutment block 364 and squeezing the torsion spring 363. When the clamping block 354 disengages from the abutment block 364, the torsion spring 363 rebounds to reset the abutment block 364 and abut against the clamping block 354 again to prevent the toggle plate 352 from shifting.

[0049] When the fixation needs to be released, pull the toggle plate 352 to make the telescopic rod 371 slide in the telescopic groove 37 and stretch the tension spring 372, move the toggle plate 352 to make the clamping block 354 disengage from the abutment block 364, rotate the toggle plate 352 to reset the extension rod 34, so that the pull wire does not contact the pull wire channel 131.

[0050] To improve the fixing effect, before installation, you can press the push plate 45 to drive the push rod 44 to move the sliding sleeve 22, stretch the telescopic spring 41 and squeeze the pressure spring 42, and the pull wire passes through the space between the oblique block 43 and the wedge block 15 into the pull wire channel 131. After passing through, it is fixed with a fixing clamp. Release the push plate 45, and the rebound force of the telescopic spring 41 and the pressure spring 42 makes the pull wire close to the angle space between the oblique block 43 and the wedge block 15, increasing the contact area. At the same time, the extension rod 34 slides to drive the gear bar 52 to move, driving the rotating gear 54 to rotate, so that the gear plate 55 moves the clamping block 56 to clamp the pull wire, further improving the fixing effect.

[0051] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
