Description

Technical Field

[0001] The utility model relates to the technical field of transmission line repair, in particular to a patch clamping mechanism for the repair operation of broken strands of transmission lines. Background Technique

[0002] Most of the regions through which transmission lines pass have relatively harsh climatic conditions. Transmission line broken strand accidents caused by strong winds, icing, lightning strikes, corrosion, etc. occur frequently. If not dealt with in time, it is extremely easy to have loose strands under the action of tension and torsion, making the safety distance between the live conductor and the transmission line unable to meet the design requirements of line operation. Continuing to develop, especially under the accelerating action of harsh weather such as strong winds, rain and snow, it will eventually develop into a line grounding short-circuit accident, resulting in the forced outage of the transmission line.

[0003] In the prior art, the repair mechanism for repairing transmission lines mainly includes a feeding device for providing patches and a clamping device for bundling and clamping the transmission line and the broken strand line with the patch. And generally, there is a lack of a supporting structure for placing the patch in the conventional clamping device. If the patch is directly placed in the center between the two clamping arms for clamping the patch, it may be difficult to effectively apply a clamping force to the patch and cause the required deformation due to the displacement (or even falling) of the patch, resulting in the scrapping of the patch and the failure of this repair.

[0034] Patch 5. Specific embodiments

[0035] The following details the embodiments of the present utility model. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0036] This technical solution provides a patch clamping mechanism for repairing broken strands in a transmission line, including a clamping seat 321, a supporting block 322, a first clamping jaw 323, and a second clamping jaw 324;

[0037] The supporting block 322 is installed at the center of the top of the clamping seat 321, and a supporting position 3221 is recessed inward on the upper surface of the supporting block 322 for receiving and placing the patch 5; the first clamping jaw 323 and the second clamping jaw 324 are respectively movably hinged to both sides of the supporting block 322;

[0038] The patch clamping mechanism includes an open state and a clamped state:

[0039] When the patch clamping mechanism is in the open state, an opening 301 is left between the first clamping jaw 323 and the second clamping jaw 324, and the opening 301 is located at the top of the patch clamping mechanism;

[0040] When the patch clamping mechanism is in the clamped state, the first clamping jaw 323 and the second clamping jaw 324 jointly enclose a clamping cavity 302, and the first clamping jaw 323 and the second clamping jaw 324 jointly clamp the patch 5 outside the transmission line.

[0041] In the prior art, in a clamping device for bundling and clamping a power transmission line (not shown in the figure) and a broken strand wire using a repair patch 5, there is generally a lack of a supporting structure for placing the repair patch 5. If the repair patch 5 is directly placed in the center of two clamping arms for clamping the repair patch 5, it is possible that due to the displacement (or even dropping) of the repair patch 5, it is difficult to effectively apply a clamping force to the repair patch 5 and cause the required deformation, resulting in the scrapping of the repair patch 5 and the failure of this repair.

[0042] Therefore, in order to ensure the effectiveness of each clamping action, a supporting block 322 is added to the repair patch clamping mechanism in this solution, as Figures 1-5 shown, and an inwardly concave supporting position 3221 for receiving and placing the repair patch 5 is provided on its upper surface to ensure the effective feeding of the repair patch 5 in the repair patch clamping mechanism and further ensure the effective realization of the repair effect in the subsequent clamping process.

[0043] Furthermore, it is described that both the first clamping jaw 323 and the second clamping jaw 324 are provided with a hinged end and a clamping end;

[0044] The hinged end and the clamping end of the first clamping jaw 323 are respectively located at both ends of the first clamping jaw 323. The first clamping jaw 323 is hinged to the supporting block 322 through the hinged end, and the first clamping jaw 323 rotates around the hinged end; an inwardly concave clamping position 3231 is provided at the edge of the clamping end.

[0045] The hinged end and the clamping end of the second clamping jaw 324 are respectively located at both ends of the second clamping jaw 324. The second clamping jaw 324 is hinged to the supporting block 322 through the hinged end, and the second clamping jaw 324 rotates around the hinged end; a clamping piece 3241 is provided protruding outward at the edge of the clamping end.

[0046] The clamping position 3231 and the clamping piece 3241 are arranged oppositely, and the clamping piece 3241 can be accommodated inside the clamping position 3231.

[0047] Furthermore, it is described that the first clamping jaw 323 and the second clamping jaw 324 jointly enclose a sealed clamping cavity 302 through the clamping position 3231 and the clamping piece 3241.

[0048] In order to avoid the effective bundling of the repair patch 5 to the power transmission line and the broken strand wire, the specific structures of the first clamping jaw 323 and the second clamping jaw 324 are also optimized in this solution, so that the first clamping jaw 323 and the second clamping jaw 324 jointly enclose a sealed clamping cavity 302 through the clamping position 3231 and the clamping piece 3241, ensuring that the repair patch 5 reaches the required clamping degree.

[0049] Furthermore, it further includes a first sliding member 325 and a second sliding member 326. The first sliding member 325 and the second sliding member 326 are installed on both inner sides of the clamping seat 321, and both the first sliding member 325 and the second sliding member 326 move horizontally relative to the clamping seat 321;

[0050] Both the first sliding member 325 and the second sliding member 326 include a displacement block 3251 and a connecting rod 3252, and the connecting rod 3252 is located on the top of the displacement block 3251;

[0051] One end of the connecting rod 3252 of the first sliding member 325 is hinged to the outer side of the top of the displacement block 3251 of the first sliding member 325, and the other end of the connecting rod 3252 is hinged to the middle of the back of the first jaw 323; the horizontal movement of the first sliding member 325 is used to drive the rotation of the first jaw 323;

[0052] One end of the connecting rod 3252 of the second sliding member 326 is hinged to the outer side of the top of the displacement block 3251 of the second sliding member 326, and the other end of the connecting rod 3252 is hinged to the middle of the back of the second jaw 324; the horizontal movement of the second sliding member 326 is used to drive the rotation of the second jaw 324.

[0053] In an embodiment of the present technical solution, the first jaw 323 rotates relative to the supporting block 322 through the first sliding member 325, and the second jaw 324 rotates relative to the supporting block 322 through the second sliding member 326; and both the first sliding member 325 and the second sliding member 326 include a displacement block 3251 and a connecting rod 3252, which can effectively convert the horizontal movement of the displacement block 3251 into the rotation of the two jaws (323, 324), with a simple structure and reliable performance.

[0054] Furthermore, the first sliding member 325 and the second sliding member 326 move synchronously towards each other and synchronously away from each other relative to the clamping seat 321.

[0055] As a preference of the above embodiment, the displacements of the first sliding member 325 and the second sliding member 326 are synchronous relative movements, which is beneficial to realizing the synchronism of the opening and closing of the two jaws (323, 324), thereby improving the clamping efficiency.

[0056] For further illustration, it further includes a clamping drive assembly 327. The clamping drive assembly 327 is installed at the bottom of the clamping seat 321. The clamping drive assembly 327 is respectively connected to the first sliding member 325 and the second sliding member 326, and the clamping drive assembly 327 is used to drive the synchronous movement of the first sliding member 325 and the second sliding member 326.

[0057] Furthermore, in this solution, a clamping drive assembly 327 for driving the synchronous movement of the first sliding member 325 and the second sliding member 326 is additionally provided in the patch clamping mechanism, and it is installed at the bottom of the clamping seat 321, which can effectively save the space occupied by the patch clamping mechanism and make the volume of the patch clamping mechanism more compact.

[0058] For further illustration, the clamping drive assembly 327 includes a synchronous lead screw 3271. The synchronous lead screw 3271 is rotatably installed inside the clamping seat 321. The displacement blocks 3251 of the first sliding member 325 and the second sliding member 326 are respectively sleeved at both ends of the synchronous lead screw 3271. The rotation of the synchronous lead screw 3271 is used to drive the synchronous approaching movement and synchronous separating movement of the first sliding member 325 and the second sliding member 326 relative to the clamping seat 321.

[0059] Specifically, in this solution, a synchronous lead screw 3271 is arranged inside the clamping seat 321 to drive the synchronous movement of the first sliding member 325 and the second sliding member 326, and the rotation of the synchronous lead screw 3271 drives the synchronous approaching movement and synchronous separating movement of the first sliding member 325 and the second sliding member 326 relative to the clamping seat 321, which can ensure the normal realization of the synchronous function on the premise of a compact volume.

[0060] For further illustration, the clamping drive assembly 327 further includes a clamping driver 3272, a first transmission wheel 3273 and a second transmission wheel 3274. The clamping driver 3272 is installed inside the clamping seat 321, and the clamping driver 3272 is located below the synchronous lead screw 3271. The first transmission wheel 3273 and the second transmission wheel 3274 are rotatably installed outside the clamping seat 321, and the first transmission wheel 3273 and the second transmission wheel 3274 are meshed with each other.

[0061] The first transmission wheel 3273 is connected to the output end of the clamping driver 3272, the second transmission wheel 3274 is connected to the end of the synchronous lead screw 3271, and the clamping driver 3272 drives the rotation of the synchronous lead screw 3271 through the first transmission wheel 3273 and the second transmission wheel 3274.

[0062] More specifically, the clamping drive assembly 327 of the present solution further includes a clamping driver 3272, a first transmission wheel 3273, and a second transmission wheel 3274, such that the clamping driver 3272 drives the rotation of the synchronous lead screw 3271 through the first transmission wheel 3273 and the second transmission wheel 3274. The transmission structure is simple and reliable, and the equipment cost is effectively reduced.

[0063] To further illustrate, the inner side surfaces of the first jaw 323 and the second jaw 324 are both C-shaped, so as to facilitate conforming to the shape of the power transmission line and completely clamping the power transmission line and the broken strand.
