Description

Technical Field

[0001] This invention relates to the field of power auxiliary equipment technology, and in particular to a wire connection device for overhead power transmission line towers. Background Technology

[0002] Spacer bars are hardware installed on split conductors to fix the spacing between each split conductor, preventing conductors from whipping each other, suppressing aerobatic vibrations and span oscillations. In long-distance, high-capacity ultra-high voltage transmission lines, each phase conductor uses two, four or more split conductors. In order to ensure that the spacing between the split conductor bundles remains unchanged to meet electrical performance requirements, reduce surface potential gradients, and prevent electromagnetic forces from being generated between conductor bundles in the event of a short circuit, causing mutual attraction and collision, or even if momentary attraction and collision occur, the conductors can return to normal after the accident is cleared, spacer bars are installed at certain intervals in the span.

[0003] Existing hardware for wire connection typically suffers from the following drawbacks: poor connection performance and inconvenience of use; it cannot effectively adjust the extension length of the adjusting rod, thus making it unsuitable for use with transmission lines of different spacings, resulting in poor adaptability of the connection hardware.

The ring assembly secures multiple wires one-to-one. The line ring assembly includes a convex end semi-circular ring and a concave end semi-circular ring, each hinged to one side of an inner slide rod. A sliding sleeve and a nut sleeve are respectively fitted onto the inner slide rod. The nut sleeve is threadedly connected to the inner slide rod.

[0023] like Figures 1-7 The image shows an embodiment of the wire connection device for overhead power transmission line towers according to the present invention.

[0024] This embodiment of the wire connection device for overhead power transmission line towers includes: a fixing ring 1; an inflation chamber shell 3 located in the middle of the fixing ring 1, with a rotating pressure arm 4 rotatably mounted on one side surface of the inflation chamber shell 3 via a rotating shaft 5, and the rotating pressure arm 4 connected to an arc-shaped inflation piston rod 7; an arc-shaped compressed air cylinder 6 fixedly mounted on the surface of the inflation chamber shell 3, the arc-shaped compressed air cylinder 6 communicating with the interior of the inflation chamber shell 3, wherein: the arc-shaped inflation piston rod 7 is slidably mounted inside the arc-shaped compressed air cylinder 6; multiple guide cylinders 2 connected between the inflation chamber shell 3 and the fixing ring 1, with an inner sliding rod 35 slidably mounted in the guide cylinder 2; a line collar assembly 12 mounted at the end of the inner sliding rod 35; a sliding connecting rod 14 mounted inside the inner sliding rod 35; and a pneumatic cylinder 8 mounted at the bottom of the guide cylinder 2, the inflation port of the pneumatic cylinder 8 communicating with the interior of the inflation chamber shell 3.

[0026] In practice, an air release valve is installed on the upper part of the air chamber shell 3, and multiple guide cylinders 2 are evenly spaced; the arc-shaped air piston rod 7 and the arc-shaped air compressor cylinder 6 are respectively set with the rotating shaft 5 as the center point of the rotation radius.

[0027] Furthermore, the line collar assembly 12 includes a convex end semicircular ring 15 and a concave end semicircular ring 21, which are respectively hinged to one side of one end of the inner slide rod 35; a sliding sleeve 10 and a nut sleeve 9 are respectively sleeved on the inner slide rod 35, and the nut sleeve 9 is threadedly connected to the inner slide rod 35. The opposite sides of the sliding sleeve 10 are respectively hinged to the convex end semicircular ring 15 and the concave end semicircular ring 21 through the hinge rod 11. The nut sleeve 9 is rotated to move along the inner slide rod 35 to push the sliding sleeve 10 to slide, thereby driving the hinge rod 11 to push the convex end semicircular ring 15 and the concave end semicircular ring 21 to close.

[0028] The inner sides of both the convex end semicircular ring 15 and the concave end semicircular ring 21 are fixedly provided with ceramic insulating anti-slip blocks 13. One end of the convex end semicircular ring 15 is fixedly provided with a mating protrusion 16, and the inner side of the concave end semicircular ring 21 is provided with a mating groove that matches the mating protrusion 16. The mating protrusion 16 is inserted into the mating groove of the concave end semicircular ring 21, and the wire is secured to the ceramic insulating anti-slip block 13.

[0029] The concave end semicircular ring 21 has a receiving groove 18 on its surface. A rotating plate 19 is rotatably provided inside the receiving groove 18. A triangular locking block 17 is fixedly provided at one end of the rotating plate 19. The mating protrusion 16 has a triangular mating groove that matches the triangular locking block 17 on its surface. A first spring 20 is fixedly provided on the inner side of the other end of the rotating plate 19. Under the action of the first spring 20, the triangular locking block 17 at one end of the rotating plate 19 is locked into the triangular mating groove in the mating protrusion 16 for limiting.

[0030] During implementation, the rotating nut sleeve 9 moves upward on the surface of the inner slide rod 35, pushing the slide sleeve 10 to slide, thereby driving the hinge rod 11 to push the convex end semicircular ring 15 and the concave end semicircular ring 21 to lock the wire through the inner ceramic insulating anti-slip block 13. At this time, the mating protrusion 16 is inserted into the mating groove inside the concave end semicircular ring 21, and the triangular locking block 17 at one end of the rotating plate 19 is locked into the triangular mating groove inside the mating protrusion 16 under the action of the first spring 20, thus completing the limiting.

[0031] Furthermore, the bottom of the nut sleeve 9 is provided with a limiting tooth groove 22; the sliding connecting rod 14 is fixedly provided with a pressing block 24 corresponding to the limiting rotation stop 23; the inner slide rod 35 is respectively equipped with the sliding connecting rod 14 and the rotatable limiting rotation stop 23, and the limiting rotation stop 23 is fixedly provided with a second spring 25 on one side of the inner surface of the inner slide rod 35, wherein: the second spring 25 pushes the limiting rotation stop 23 to rotate, so that it is engaged in the limiting tooth groove 22, thereby limiting the nut sleeve 9; pressing the sliding connecting rod 14 drives the pressing block 24 to move downward and press the limiting rotation stop 23 to rotate, so that it disengages from the limiting tooth groove 22, thereby releasing the limiting of the nut sleeve 9.

[0032] In practice, several limiting tooth grooves 22 are provided, and the limiting rotation stop bar 23 is set corresponding to the limiting tooth groove 22. The second spring 25 pushes the limiting rotation stop bar 23 to rotate, thereby locking into the limiting tooth groove 22 on the lower surface of the nut sleeve 9 to prevent the nut sleeve 9 from rotating. Pressing the sliding connecting rod 14 drives the pressing block 24 to move downward to press the limiting rotation stop bar 23 to rotate, so that it is disengaged from the limiting tooth groove 22. At this time, the nut sleeve 9 can rotate.

[0033] Preferably, the cross-section of the limiting rotation stop 23 is L-shaped, the cross-section of the extrusion block 24 is trapezoidal, and the hypotenuse of the extrusion block 24 is in close contact with the limiting rotation stop 23.

[0034] Furthermore, a fixed stop 26 is installed on the sliding link 14, a fixed baffle 28 is fixedly installed inside the inner slide rod 25, and a third spring 27 is sleeved on the sliding link 14, with the third spring 27 connected between the fixed stop 26 and the fixed baffle 28.

[0035] The inner slide rod 35 has a retaining groove 33 on its inner side at the end. A rotating sleeve 30 is rotatably mounted in the middle of the retaining groove 33 via a bearing. The rotating sleeve 30 is connected to the limiting triangular block 32 via a steel wire rope. The limiting triangular block 32 is slidably mounted on both sides inside the retaining groove 33. A fourth spring 31 is provided between the inner wall of the retaining groove 33 and the limiting triangular block 32. The guide cylinder 2 has triangular anti-backward retaining grooves 36 on both sides inside. The limiting triangular block 32 is correspondingly mounted to the triangular anti-backward retaining grooves 36. A sliding protrusion 29 is fixedly mounted on one end of the sliding connecting rod 14. A spiral groove 34 is provided on the inner surface of the rotating sleeve 30. The sliding protrusion 29 is slidably mounted on the inner side of the spiral groove 34.

[0036] During implementation, pressing the sliding link 14 causes it to slide in the spiral groove 34 inside the rotating sleeve 30 via the sliding protrusion 29, which in turn causes the rotating sleeve 30 to rotate and pull the retractable wire rope, thereby pulling the limiting triangular block 32 out of the triangular anti-backward slot 36; when the sliding link 14 is released, the third spring 27 causes the sliding link 14 to slide back to its original position, the rotating sleeve 30 reverses, the wire rope is released, and the fourth spring 31 causes the limiting triangular block 32 to insert into the triangular anti-backward slot 36.

[0037] In this embodiment, the wire connection device for overhead power transmission line towers is implemented by repeatedly pressing and rotating the pressure arm 4, which drives the arc-shaped inflation piston rod 7 to inflate the inflation chamber shell 3 inside the arc-shaped compressed air cylinder 6, thereby completing the inflation of the air cylinder 8, driving the inner slide rod 35 to slide inside the guide cylinder 2, thereby adjusting the length, and releasing pressure through the air release valve.

[0038] The rotating nut sleeve 9 moves upward on the surface of the inner slide rod 35, pushing the slide sleeve 10 to slide, thereby driving the hinge rod 11 to push the convex end semicircular ring 15 and the concave end semicircular ring 21 to lock the wire through the inner ceramic insulating anti-slip block 13. At this time, the mating protrusion 16 is inserted into the mating groove in the concave end semicircular ring 21. Under the action of the first spring 20, the triangular locking block 17 at one end of the rotating plate 19 is locked into the triangular mating groove in the mating protrusion 16, completing the limiting.

[0039] The second spring 25 pushes the limiting rotation stop 23 to rotate, thereby engaging in the limiting tooth groove 22 on the lower surface of the nut sleeve 9, preventing the nut sleeve 9 from rotating. Pressing the sliding connecting rod 14 drives the pressing block 24 to move downwards and press the limiting rotation stop 23 to rotate, causing it to disengage from the limiting tooth groove 22. At this time, the nut sleeve 9 can rotate.

[0040] When the sliding link 14 is pressed, it slides downward through the spiral groove 34 inside the rotating sleeve 30 via the sliding protrusion 29, thereby driving the rotating sleeve 30 to rotate and pulling the retractable steel wire rope, thereby pulling the limiting triangle block 32 out of the triangular anti-backward slot 36; when the sliding link 14 is released, the third spring 27 drives the sliding link 14 to slide upward and reset, and at the same time the rotating sleeve 30 reverses to release the steel wire rope. The fourth spring 31 drives the limiting triangle block 32 to insert into the triangular anti-backward slot 36 to prevent the inner slide rod 35 from retracting due to loss of pressure in the pneumatic cylinder 8.

The system includes a wire collar assembly at the end of the slide rod; a sliding connecting rod installed inside the inner slide rod; and a pneumatic cylinder installed at the bottom of the guide cylinder. The air inlet of the pneumatic cylinder is connected to the inside of the inflation chamber. By repeatedly pressing and rotating the pressure arm, the arc-shaped inflation piston rod reciprocates inside the arc-shaped compressed air cylinder, inflating the inflation chamber. The pneumatic cylinder then pushes the inner slide rod, causing it to slide along the guide cylinder, thus adjusting the length of the inner slide rod extending out of the guide cylinder. Multiple wire collar assemblies are used to secure multiple wires one-to-one, allowing for length adjustment of the wire collar assemblies used for wire connections, improving work efficiency.
