Description

Technical Field

[0001] The utility model relates to the technical field of transmission line repair, in particular to a feeding mechanism for repair patches in 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 and other reasons occur frequently. If not dealt with in time, it is very easy to have loose strands under the action of tension and torsion, so that the safety distance between the live conductor and the transmission line cannot meet the design requirements of line operation. Continuing to develop, especially under the acceleration 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 repair patches and a clamping device for bundling and clamping the transmission line and the broken strand line with the repair patches. And in the feeding devices in the prior art, generally, the repair patches are stacked together, pushed up tightly by a spring in the feeding device, and the repair patches are pushed to the discharge end one by one horizontally through a push rod. When the thickness of the repair patch 5 is small, the pushing gap left for the push rod is small, and the shape and size of the repair patch are required to be very accurate. This is because if there is a slight error in the shape processing of the repair patch, the push rod is likely to push out together with the next repair patch, resulting in the jamming of the feeding action and unable to realize the continuous progress of the feeding action.

[0026] repair patch 5. Detailed Embodiment

[0027] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the 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.

[0028] This technical solution provides a repair patch feeding mechanism for repairing broken strands of a transmission line, including a storage seat 332 and a pusher block 333;

[0029] A storage cavity 3324 extending in the horizontal direction is formed at the top of the storage base 332, and multiple repair patches 5 are horizontally arranged and accommodated inside the storage cavity 3324. The pusher block 333 is horizontally movably installed inside the storage cavity 3324, and the pusher block 333 is located at the outer end of the storage cavity 3324. The pusher block 333 is used to push the repair patch 5 out of the inner end of the storage cavity 3324.

[0030] In the prior art, for the feeding device that provides the repair patch 5, the repair patches 5 are generally stacked together, and a spring in the feeding device is used to push them tightly upward, and the repair patches 5 are pushed one by one to the discharging end horizontally through a push rod. When the thickness of the repair patch 5 is small, the pushing gap left for the push rod is small, and the shape and size of the repair patch 5 need to be very accurate. This is because if there is a slight error in the shape processing of the repair patch 5, the push rod is likely to push out the next repair patch 5 together, resulting in jamming of the feeding action and inability to continuously perform the feeding action.

[0031] Therefore, in order to ensure the effective supply of the repair patch 5, the repair patch feeding mechanism of this technical solution includes a storage base 332 and a pusher block 333. The repair patches 5 are arranged side by side and laid flat in the storage cavity 3324 at the top of the storage base 332. As Figures 1-4 shown, the repair patch 5 is fed forward by the pusher block 333 and pushed to the output end (i.e., the inner end) of the storage cavity 3324 to complete the feeding function. For the side-by-side laying of the repair patches 5, no matter how thin the repair patch 5 is, it can ensure that only one repair patch 5 is pushed out at a time, and the requirement for the machining accuracy of the shape and size of the repair patch 5 is not high.

[0032] Furthermore, a pushing gap 3325 extending in the horizontal direction is formed at the bottom of the storage base 332, and the storage cavity 3324 and the pushing gap 3325 are in communication with each other;

[0033] The repair patch feeding mechanism further includes a pushing drive assembly 334. The pushing drive assembly 334 is installed at the bottom of the storage base 332, and the output end of the pushing drive assembly 334 passes through the pushing gap 3325 and is connected to the pusher block 333. The pushing drive assembly 334 is used to drive the horizontal movement of the pusher block 333.

[0034] In an embodiment of this technical solution, the horizontal movement of the pusher block 333 is realized by the pushing drive assembly 334, with a simple structure and reliable performance. Moreover, the pushing drive assembly 334 of this solution is installed at the bottom of the storage base 332, and its output end is connected to the pusher block 333 through the pushing gap 3325 that is in communication with the storage cavity 3324, which can make the structure of the repair patch feeding mechanism more compact on the premise of ensuring the horizontal movement of the pusher block 333.

[0035] Further explanation, the pusher driving assembly 334 includes a pusher driver 3341 and a telescopic sleeve rod 3342; the pusher driver 3341 is located at the inner end of the storage seat 332, one end of the telescopic sleeve rod 3342 is connected to the output end of the pusher driver 3341, and the other end of the telescopic sleeve rod 3342 is connected to the outer end of the pusher block 333. The pusher driver 3341 is used to drive the telescopic sleeve rod 3342 to extend and contract.

[0036] As a preference of the above embodiment, the pusher driving assembly 334 includes a pusher driver 3341 and a telescopic sleeve rod 3342. The pusher driver 3341 drives the telescopic sleeve rod 3342 to extend and contract, thereby driving the pusher block 333 to move horizontally in the storage cavity 3324, which is beneficial to increasing the moving range of the pusher block 333 without increasing the structural volume.

[0037] Further explanation, it further includes a pressing block 335. The pressing block 335 is detachably installed on the top of the storage seat 332, and the shape of the pressing block 335 matches the shape of the storage cavity 3324.

[0038] A pusher channel is left between the storage seat 332 and the pressing block 335, and the pusher channel is used to avoid the repair patch 5 and the pusher block 333.

[0039] In another embodiment of the present technical solution, in order to avoid the stacking of the repair patches 5 arranged side by side in the storage cavity 3324, a pressing block 335 is further provided on the top of the storage seat 332, so that a pusher channel (not marked in the figure) that can only accommodate one repair patch 5 is left between the storage seat 332 and the pressing block 335, so as to further ensure that only one repair patch 5 is pushed out at a time.

[0040] Further explanation, the storage seat 332 includes a first fixing part 3321, a storage part 3322 and a second fixing part 3323 connected in sequence. The upper surfaces of the first fixing part 3321 and the second fixing part 3323 are both horizontal planes, and the storage cavity 3324 is formed in the storage part 3322.

[0041] Further explanation, the pressing block 335 includes a first fixing plate 3351, a pressing part 3352 and a second fixing plate 3353 formed integrally.

[0042] The lower surfaces of the first fixing plate 3351 and the second fixing plate 3353 are both horizontal planes, and the upper surface of the first fixing part 3321 is attached to the lower surface of the first fixing plate 3351, and the upper surface of the second fixing part 3323 is attached to the lower surface of the second fixing plate 3353.

[0043] A pushing channel is left between the material storage part 3322 and the pressing part 3352.

[0044] As a preference of the above embodiment, the present solution also optimizes the shapes of the material storage base 332 and the pressing block 335 to facilitate the disassembly and installation of the two.

[0045] Further illustration, the shape of the material storage cavity 3324 is U-shaped, and the lower surface of the pressing part 3352 is U-shaped.

[0046] Further illustration, the outer ends of the material storage cavity 3324 and the pushing gap 3325 are aligned with each other, and the length of the material storage cavity 3324 is greater than the length of the pushing gap 3325.

[0047] Furthermore, the present solution also optimizes the lengths of the material storage cavity 3324 and the pushing gap 3325, so that the inner end of the pushing gap 3325 serves as the limit of the stroke of the pushing block 333, to ensure that the repair patch 5 can be just pushed out of the repair patch feeding mechanism, to prevent the deformation or dropping of the repair patch 5 caused by excessive pushing.
