Description

Technical Field

[0001] The utility model relates to the technical field of power transmission line repair, in particular to a repair mechanism for repairing broken strands of a power transmission line. Background Art

[0002] Most areas along which power transmission lines pass have relatively harsh climatic conditions. Transmission line strand breakage accidents caused by strong winds, icing, lightning strikes, corrosion, and other reasons often occur. If not handled in a timely manner, strands can easily become loose under the action of tension and torsion, making it impossible for the safe distance between live conductors and transmission lines to meet the design requirements for line operation. If this continues, especially under the accelerated action of severe weather such as strong winds, rain, and snow, it will eventually develop into a line grounding short circuit accident, forcing the transmission line to be forced to stop operating.

[0003] The repair mechanism used in the prior art for repairing power transmission lines mainly includes a feeding device for providing repair sheets and a clamping device for bundling and clamping the power transmission line and the broken wire using the repair sheets. The two devices are independently installed on the top of the repair platform and are far apart. On the one hand, this is not conducive to the effective delivery of the repair sheets, and on the other hand, it is not conducive to reducing the volume of the repair mechanism.

[0047] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0048] This technical solution provides a repair mechanism for repairing broken strands in a transmission line, comprising a mounting base 31, a clamping device 32, and a feeding device 33. The mounting base 31 is mounted on the outside of a mounting frame (not shown), and the clamping device 32 and the feeding device 33 are sequentially mounted on the mounting base 31 from the inside to the outside. The clamping device 32 moves up and down relative to the mounting base 31.

[0049] The repair mechanism further includes a mounting bracket 35; the mounting bracket 35 includes a connecting end and a mounting end, the connecting end being connected to the mounting surface 311 of the mounting seat 31, and the mounting end being used to mount the feeding device 33; the connecting end is located below the clamping device 32, and the mounting end is located within the movement range of the active end of the clamping device 32;

[0050] The feeding device 33 is used to transport the patch 5 to the active end of the clamping device 32 , and the clamping device 32 is used to clamp the broken part of the power transmission line using the patch 5 .

[0051] The repair mechanism used in the prior art for repairing power transmission lines mainly includes a feeding device for providing a patch sheet 5 and a clamping device for bundling and clamping the power transmission line (not shown in the figure) and the broken strand using the patch sheet 5. The two devices are independently installed on the top of the repair platform and are far apart. On the one hand, this is not conducive to the effective delivery of the patch sheet 5, and on the other hand, it is not conducive to reducing the volume of the repair mechanism.

[0052] In order to solve the above technical problems, the repair mechanism proposed in this solution includes a mounting seat 31, a clamping device 32 for clamping the broken part of the transmission line with the repair piece 5, and a feeding device 33 for feeding the repair piece 5 to the clamping device 32. Figure 1-3 Specifically, the clamping device 32 and feeding device 33 of this solution are sequentially mounted on the mounting base 31 from the inside out, effectively reducing the distance between the two devices. Furthermore, the feeding device 33 is mounted on the mounting surface 311 of the mounting base 31 via a mounting bracket 35, and the mounting end is positioned within the moving range of the active end of the clamping device 32. This reduces the distance between the discharge end of the feeding device 33 and the active end of the clamping device 32, enabling seamless transfer of the patch 5 from the feeding device 33 to the clamping device 32 while making the repair mechanism more compact.

[0053] It should be noted that the repair process of the repair mechanism of this scheme is as follows: the broken part of the straightened transmission line is located at the top of the repair mechanism; first, the clamping device 32 is moved downward relative to the mounting seat 31, so that the feeding device 33 conveys the repair piece 5 to the active end of the clamping device 32; then the clamping device 32 is moved upward relative to the mounting seat 31, and the repair piece 5 in the clamping device 32 is abutted against the bottom of the broken part of the straightened transmission line. The clamping device 32 clamps the repair piece 5, so that the transmission line and the broken strand are bundled to achieve repair.

[0054] To further illustrate, the repair mechanism further includes a lifting device 34, which is disposed between the mounting seat 31 and the clamping device 32. The clamping device 32 is moved up and down relative to the mounting seat 31 by the lifting device 34.

[0055] The lifting device 34 includes a lifting drive 341, a lifting rod 342 and a lifting transmission block 343; the lifting drive 341 is installed at the lower part of the mounting surface 311, and the lifting drive 341 is located below the mounting bracket 35; the lifting transmission block 343 is protrudingly installed on the upper part of the inner wall of the clamping device 32; the lifting rod 342 extends vertically through the mounting bracket 35, and the end of the lifting rod 342 is connected to the output end of the lifting drive 341, and the top of the lifting rod 342 is connected to the lifting transmission block 343, and the lifting drive 341 is used to drive the clamping device 32 to move up and down through the lifting rod 342.

[0056] In one embodiment of this technical solution, the clamping device 32 is moved up and down relative to the mounting base 31 using a lifting device 34. Specifically, the lifting device 34 includes a lifting driver 341, a lifting rod 342, and a lifting transmission block 343. The lifting driver 341 drives the clamping device 32 up and down via the lifting rod 342, resulting in a simple structure and reliable performance. Furthermore, the coordinated positional relationship between the lifting device 34 and the mounting bracket 35 makes the structural design of the repair mechanism more compact.

[0057] To further explain, the lifting device 34 also includes a guide rail 344 and a guide slider 345; the guide rail 344 is vertically extended and installed on both sides of the upper part of the installation surface 311, and the guide slider 345 is protrudingly installed on both sides of the lower part of the inner wall of the clamping device 32; a vertically extending slide groove 3451 is opened on the inner side of the guide slider 345, and the guide slider 345 can be slidably installed on the guide rail 344 through the slide groove 3451.

[0058] As a preferred embodiment of the above embodiment, the lifting device 34 also includes a guide rail 344 and a guide slider 345. The guide slider 345 can be slidably installed on the guide rail 344 through a slide groove 3451. On the one hand, it is beneficial to increase the connection strength between the clamping device 32 and the mounting seat 31 and reduce the load on the lifting drive 341 and the lifting rod 342. On the other hand, it is beneficial to ensure the stable movement of the clamping device 32 on the mounting seat 31.

[0059] To further illustrate, the feeding device 33 includes a storage seat 332 and a pushing block 333;

[0060] A storage cavity 3324 extending in the horizontal direction is provided at the top of the storage seat 332, and multiple repair pieces 5 are accommodated in the interior of the storage cavity 3324 in parallel in the horizontal direction; the pushing block 333 can be horizontally movably installed in the interior of the storage cavity 3324, and the pushing block 333 is located at the outer end of the storage cavity 3324, and the pushing block 333 is used to push the repair piece 5 out of the inner end of the storage cavity 3324.

[0061] In the prior art, a feeding device for providing patch sheets 5 generally stacks the patch sheets 5 together, uses a spring in the feeding device to push the sheets upward, and then pushes the patch sheets 5 horizontally one by one to the discharge end. When the thickness of the patch sheet 5 is relatively small, the clearance left for the pusher to push out is relatively small, and the shape and size of the patch sheet 5 must be very accurate. This is because if there is a slight error in the shape processing of the patch sheet 5, the pusher may easily push out the next patch sheet 5 together, causing the feeding action to be blocked and preventing continuous feeding.

[0062] Therefore, in order to ensure the effective supply of the patch 5, the present technical solution lays the patch 5 side by side in the storage cavity 3324, as shown in FIG. Figure 4-7 As shown, the pusher block 333 pushes the patch 5 forward to the output end (i.e., the inner end) of the storage chamber 3324, completing the feeding function. The patch 5 is laid out side by side, ensuring that only one patch 5 is pushed out at a time, regardless of how thin the patch 5 is, and the shape and size of the patch 5 do not require high processing accuracy.

[0063] To further illustrate, a material pushing gap 3325 extending in the horizontal direction is formed at the bottom of the material storage seat 332, and the material storage cavity 3324 and the material pushing gap 3325 are communicated with each other;

[0064] The feeding device 33 also includes a pushing drive component 334, which is installed at the bottom of the storage seat 332, and the output end of the pushing drive component 334 passes through the pushing gap 3325 and is connected to the pushing block 333. The pushing drive component 334 is used to drive the horizontal movement of the pushing block 333.

[0065] In one embodiment of this technical solution, horizontal movement of the pusher block 333 is achieved through a pusher drive assembly 334, resulting in a simple structure and reliable performance. Furthermore, the pusher drive assembly 334 of this solution is mounted at the bottom of the storage base 332, with its output end connected to the pusher block 333 via a pusher gap 3325 that communicates with the storage chamber 3324. This allows for a more compact structure of the feeder 33 while ensuring horizontal movement of the pusher block 333.

[0066] To further explain, the pushing drive assembly 334 includes a pushing drive 3341 and a telescopic sleeve 3342; the pushing drive 3341 is located at the inner end of the storage seat 332, one end of the telescopic sleeve 3342 is connected to the output end of the pushing drive 3341, and the other end of the telescopic sleeve 3342 is connected to the outer end of the pushing block 333, and the pushing drive 3341 is used to drive the extension and retraction of the telescopic sleeve 3342.

[0067] As a preferred embodiment of the above embodiment, the pushing drive assembly 334 includes a pushing drive 3341 and a telescopic sleeve 3342. The pushing drive 3341 drives the telescopic sleeve 3342 to extend and retract, thereby driving the pushing block 333 to move horizontally in the storage chamber 3324, which is beneficial to increase the moving range of the pushing block 333 without increasing the structural volume.

[0068] Further, the feeding device 33 further includes a pressing block 335, which is detachably mounted on the top of the storage seat 332, and the shape of the pressing block 335 matches the shape of the storage cavity 3324;

[0069] A material pushing channel is reserved between the material storage seat 332 and the pressing block 335 , and the material pushing channel is used to avoid the repair piece 5 and the material pushing block 333 .

[0070] In another embodiment of the present technical solution, in order to avoid stacking of the patch pieces 5 arranged side by side in the storage chamber 3324, the present solution further provides a clamping block 335 on the top of the storage seat 332, so that a pushing channel (not shown in the figure) that can only accommodate one patch piece 5 is left between the storage seat 332 and the clamping block 335, to further ensure that only one patch piece 5 is pushed out at a time.

[0071] Preferably, the material storage seat 332 includes a first fixed part 3321, a material storage part 3322 and a second fixed part 3323 connected in sequence, the upper surfaces of the first fixed part 3321 and the second fixed part 3323 are both horizontal planes, the material storage part 3322 is provided with the material storage cavity 3324, and the shape of the material storage cavity 3324 is U-shaped.

[0072] Preferably, the pressing block 335 includes an integrally formed first fixing plate 3351 , a pressing portion 3352 , and a second fixing plate 3353 ;

[0073] The lower surfaces of the first fixing plate 3351 and the second fixing plate 3353 are both horizontal surfaces, and the upper surface of the first fixing portion 3321 is in contact with the lower surface of the first fixing plate 3351, and the upper surface of the second fixing portion 3323 is in contact with the lower surface of the second fixing plate 3353;

[0074] The lower surface of the pressing portion 3352 is U-shaped, and the material pushing channel is reserved between the material storage portion 3322 and the pressing portion 3352 .

[0075] As a preferred embodiment of the above embodiment, the present solution further optimizes the shapes of the material storage seat 332 and the pressing block 335 to facilitate the disassembly and installation of the two.

[0076] To further illustrate, the outer end of the storage cavity 3324 and the outer end of the pushing gap 3325 are aligned with each other, and the length of the storage cavity 3324 is greater than the length of the pushing gap 3325.

[0077] Furthermore, this solution also optimizes the length of the storage cavity 3324 and the length of the pushing gap 3325, so that the inner end of the pushing gap 3325 serves as a limit for the stroke of the pushing block 333, to ensure that the repair piece 5 can be just pushed out of the feeding device 33, to prevent the repair piece 5 from being deformed or falling due to excessive pushing.

[0078] To further illustrate, the clamping device 32 includes a clamping seat 321, a supporting block 322, a first clamping jaw 323, and a second clamping jaw 324; the clamping seat 321 is mounted on the outside of the mounting seat 31, and the clamping seat 321 moves up and down relative to the mounting seat 31;

[0079] The supporting block 322 is mounted at the top center of the clamping seat 321, and the upper surface of the supporting block 322 is recessed to form a supporting position 3221, which is used to receive and place the repair piece 5 pushed out by the feeding device 33; the first clamping jaw 323 and the second clamping jaw 324 are respectively movably hinged to the two sides of the supporting block 322;

[0080] The clamping device 32 includes an open state and a clamping state:

[0081] When the clamping device 32 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 clamping device 32 ;

[0082] When the clamping device 32 is in the clamping state, the first clamping jaw 323 and the second clamping jaw 324 together form a clamping cavity 302 , and the first clamping jaw 323 and the second clamping jaw 324 are used together to clamp the patch 5 to the outside of the power transmission line.

[0083] In the prior art, the clamping device used to bundle and clamp the power transmission line and the broken wire using the patch 5 generally lacks a supporting structure for placing the patch 5. If the patch 5 is directly placed in the center of the two clamping arms used to clamp the patch 5, it is possible that the patch 5 will be displaced (or even fall), making it difficult to effectively apply the clamping force to the patch 5 and cause it to undergo the required deformation, thereby resulting in the scrapping of the patch 5 and the failure of the repair.

[0084] Therefore, in order to ensure the effectiveness of each clamping action, the present invention adds a support block 322 to the clamping device 32, such as Figure 8-12 As shown, the upper surface thereof is provided with a concave supporting position 3221 for receiving and placing the repair piece 5, so as to ensure the effective loading of the repair piece 5 in the clamping device 32, and further ensure the effective realization of the repair effect in the subsequent clamping process.

[0085] Preferably, the inner side surfaces of the first clamping jaw 323 and the second clamping jaw 324 are both C-shaped.

[0086] So as to fit the shape of the transmission line and completely clamp the transmission line and the broken strand.

[0087] To further illustrate, both the first clamping jaw 323 and the second clamping jaw 324 are provided with a hinge end and a clamping end;

[0088] The hinge end of the first clamping jaw 323 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 via the hinge end, and the first clamping jaw 323 rotates around the hinge end. The edge of the clamping end is recessed inward to form a clamping position 3231.

[0089] 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 via the hinged end, and the second clamping jaw 324 rotates around the hinged end. A clamping piece 3241 is protruding outward from the edge of the clamping end.

[0090] The clamping position 3231 and the clamping piece 3241 are arranged opposite to each other, and the clamping piece 3241 can be accommodated inside the clamping position 3231 . The first clamping jaw 323 and the second clamping jaw 324 jointly form a sealed clamping cavity 302 through the clamping position 3231 and the clamping piece 3241 .

[0091] In order to avoid the effective bundling of the transmission line and the broken wire by the patch 5, the present solution also optimizes the specific structure of the first clamping jaw 323 and the second clamping jaw 324, so that the first clamping jaw 323 and the second clamping jaw 324 can jointly form a sealed clamping cavity 302 through the clamping position 3231 and the clamping piece 3241 to ensure that the patch 5 reaches the required clamping degree.

[0092] Preferably, the clamping device 32 further includes a first sliding member 325 and a second sliding member 326, wherein the first sliding member 325 and the second sliding member 326 are installed on both sides of the interior of the clamping seat 321, and the first sliding member 325 and the second sliding member 326 both move horizontally relative to the clamping seat 321;

[0093] The first sliding member 325 and the second sliding member 326 each 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 ;

[0094] One end of the connecting rod 3252 of the first sliding member 325 is hinged to the top outer side 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 side of the first clamping jaw 323. The horizontal movement of the first sliding member 325 is used to drive the rotation of the first clamping jaw 323.

[0095] One end of the connecting rod 3252 of the second sliding member 326 is hinged to the top outer side 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 side of the second clamping jaw 324; the horizontal movement of the second sliding member 326 is used to drive the rotation of the second clamping jaw 324.

[0096] In one embodiment of the present technical solution, the first clamping jaw 323 is rotated relative to the supporting block 322 through the first sliding member 325, and the second clamping jaw 324 is rotated relative to the supporting block 322 through the second sliding member 326; and the first sliding member 325 and the second sliding member 326 both 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 clamping jaws (323, 324), with a simple structure and reliable performance.

[0097] Preferably, the first sliding member 325 and the second sliding member 326 move toward each other and away from each other synchronously relative to the clamping seat 321 .

[0098] As a preference of the above embodiment, the displacement of the first sliding member 325 and the second sliding member 326 is synchronous relative movement, which is conducive to achieving the synchronization of opening and closing of the two clamping jaws (323, 324), thereby improving the clamping efficiency.

[0099] Preferably, the clamping device 32 also includes a clamping drive assembly 327, which 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.

[0100] Furthermore, this solution also adds a clamping drive component 327 to the clamping device 32 for driving the first sliding member 325 and the second sliding member 326 to move synchronously, and it is installed at the bottom of the clamping seat 321, which can effectively save the space occupied by the clamping device 32 and make the volume of the clamping device 32 more compact.

[0101] Preferably, the clamping drive assembly 327 includes a synchronization screw 3271, which is rotatably mounted inside the clamping seat 321; the displacement block 3251 of the first sliding member 325 and the displacement block 3251 of the second sliding member 326 are respectively mounted on both ends of the synchronization screw 3271, and the rotation of the synchronization screw 3271 is used to drive the first sliding member 325 and the second sliding member 326 to move toward each other and move away from each other synchronously relative to the clamping seat 321.

[0102] Specifically, this solution sets a synchronization screw 3271 inside the clamping seat 321 to drive the synchronous movement of the first sliding member 325 and the second sliding member 326, so that the rotation of the synchronization screw 3271 drives the first sliding member 325 and the second sliding member 326 to move toward each other and toward each other relative to the clamping seat 321, thereby ensuring the normal implementation of the synchronization function while maintaining a compact size.

[0103] Preferably, 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 is located below the synchronization screw 3271; the first transmission wheel 3273 and the second transmission wheel 3274 are rotatably installed on the outside of the clamping seat 321, and the first transmission wheel 3273 and the second transmission wheel 3274 are engaged with each other;

[0104] The first transmission wheel 3273 is connected to the output end of the clamping driver 3272, and the second transmission wheel 3274 is connected to the end of the synchronization screw rod 3271. The clamping driver 3272 drives the rotation of the synchronization screw rod 3271 through the first transmission wheel 3273 and the second transmission wheel 3274.

[0105] More specifically, the clamping drive assembly 327 of this solution also includes a clamping driver 3272, a first transmission wheel 3273 and a second transmission wheel 3274, so that the clamping driver 3272 drives the rotation of the synchronous screw rod 3271 through the first transmission wheel 3273 and the second transmission wheel 3274. The transmission structure is simple and reliable, and effectively reduces equipment costs.

[0106] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form.

[0107] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0108] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0109] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0110] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components.
