[0002] During the construction and operation of high-voltage transmission lines, weather conditions or external forces can cause cross-sectional wear, damage, and breakage of high-voltage conductors. Broken strands can affect power transmission and reduce the mechanical properties of the conductor, even leading to complete line breakage. Therefore, repair measures must be taken at the damaged areas to ensure the conductor's transmission cross-section and tensile strength. According to the national standard GBJ233 "Code for Construction and Acceptance of 110~550KV Overhead Power Lines", steel-cored aluminum alloy stranded wires with damaged areas at the same cross-section accounting for 7% to 25% of the total area of ​​the aluminum strands should be repaired using repair pipes.

[0003] Currently, most repair solutions for broken-strand pipes rely on manual operation, involving the straightening and crimping of the broken strands. However, manual straightening and crimping are tedious, time-consuming, labor-intensive, risky, and require highly skilled operators, severely impacting the efficiency of pipe repair.

[0032] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0033] Please refer to Figures 1 to 6 A straightening and crimping mechanism for transmission line repair pipes includes a workbench and a guide rail 1, a first linear drive 2, a straightening device, and a crimping device 6 located on the workbench.

[0034] The straightening device includes a clamping assembly 3, a clamping block 4, and a first rotation drive assembly 5;

[0035] The clamping assembly 3 is slidably disposed on the guide rail 1, and the movable end of the first linear drive member 2 is connected to the clamping assembly 3, and the direction of movement of the movable end is parallel to the track direction of the guide rail 1.

[0036] The clamping block 4 is rotatably mounted on the movable end of the clamping assembly 3. The clamping block 4 has a clamping channel 7 for the repair tube to pass through. The clamping channel 7 is parallel to the guide rail 1. The opening of the clamping channel 7 is provided with a flared opening 8.

[0037] The first rotation drive assembly 5 is connected to the clamping block 4 in a transmission manner, and is used to drive the clamping block 4 to rotate;

[0038] The crimping interface of the crimping device 6 is located on the same straight line as the clamping channel 7, and is used to crimp the repair tube onto the broken strand of the conductor.

[0039] As can be seen from the above description, the beneficial effects of the present invention are as follows: A clamping assembly 3, a clamping block 4, and a first rotation drive assembly 5 are provided on the guide rail 1. The clamping assembly 3 and the clamping block 4 cooperate to clamp the repair tube on the broken strand of the wire. The first linear drive member 2 and the first rotation drive assembly 5 serve as driving forces to control the clamping block 4 to rotate while driving the repair tube to slide on the broken strand of the wire. This allows the flared mouth 8 to cooperate with the repair tube, straightening and gathering the broken strand at the broken strand into the repair tube. After the straightening operation is completed, the repair tube is pressed and fixed by the crimping device 6, replacing manual operation, reducing the difficulty of straightening and crimping the repair tube, and improving the efficiency of repair tube repair.

[0040] Furthermore, it also includes a broken wire straightening assembly and a second linear drive 9 located on the workbench;

[0041] The broken wire straightening assembly includes a fixing base 10, a wire bundle block 11, and a second rotation drive assembly 12;

[0042] The fixed base 10 is slidably disposed on the guide rail 1, and the movable end of the second linear drive member 9 is connected to the fixed base 10, and the direction of movement of the movable end is parallel to the track direction of the guide rail 1.

[0043] The wire harness block 11 is rotatably mounted on the fixed base 10. The wire harness block 11 has a wire through hole 13 for the broken strand of wire to pass through. The wire through hole 13 and the clamping channel 7 are located on the same straight line. The flared mouth 8 is located on the channel opening of the clamping channel 7 facing the wire through hole 13.

[0044] The second rotation drive assembly 12 is connected to the wire harness block 11 for driving the wire harness block 11 to rotate.

[0045] As described above, a broken wire straightening assembly and a second linear drive 9 are also provided in the track direction of the guide rail 1. When the clamping block 4 rotates and drives the repair tube to slide on the broken wire, so that the flared mouth 8 cooperates with the repair tube to straighten and gather the broken wire on one side of the broken wire into the repair tube, the second linear drive 9 and the second rotation drive assembly 12 are used as power to control the wire bundle block 11 to rotate and slide on the broken wire, thereby straightening and gathering the broken wire on the other side of the broken wire until the wire bundle block 11 and the clamping block 4 contact the broken wire. This allows the straightening and gathering of the wires on both sides of the broken wire to be completed automatically, significantly shortening the operation time and improving the operation efficiency.

[0046] Furthermore, the clamping assembly 3 includes a base and a third linear drive 31, a first splicing plate 32 and a second splicing plate 33 located on the base;

[0047] The first splicing plate 32 is disposed on the movable end of the third linear drive member 31, and the movable end of the third linear drive member 31 faces the second splicing plate 33;

[0048] Both the first splicing plate 32 and the second splicing plate 33 are provided with a semi-circular groove 34;

[0049] The clamping block 4 includes two sub-clamping blocks 41. Each sub-clamping block 41 has a semi-circular edge portion 42 that is adapted to the size of the semi-circular groove 34. Each sub-clamping block 41 corresponds to the semi-circular groove 34 and is rotatably disposed in the semi-circular groove 34 through the semi-circular edge portion 42.

[0050] When the first splicing plate 32 and the second splicing plate 33 are spliced ​​together, the two sub-clamping blocks 41 are spliced ​​together to form the clamping block 4 and the clamping channel 7, and the two semi-circular grooves 34 are spliced ​​together to form a rotation space for the clamping block 4 to rotate.

[0051] As can be seen from the above description, the clamping assembly 3 adopts a splicing combination structure. The semi-circular grooves 34 and sub-clamping blocks 41 on the first splicing plate 32 and the second splicing plate 33 correspond to each other. In use, the broken wire and the repair tube only need to be placed between the first splicing plate 32 and the second splicing plate 33 at the position corresponding to the sub-clamping block 41. By moving the first splicing plate 32 back and forth, the clamping and loosening operations can be realized. The structure is simple, easy to control, and cleverly coordinated.

[0052] Furthermore, the first rotation drive assembly 5 includes a rotation motor 51, a drive gear 52, and a driven gear 53;

[0053] The rotating motor 51 is mounted on the clamping assembly 3, the driving gear 52 is mounted on the movable end of the rotating motor 51, and the driven gear 53 is mounted on the clamping block 4.

[0054] The driving gear 52 is meshed with the driven gear 53.

[0055] As can be seen from the above description, the transmission is achieved by meshing the driving gear 52 and the driven gear 53, which makes the rotation control of the clamping block 4 more stable and reliable.

[0056] Furthermore, the crimping device 6 includes an electric hydraulic clamp 61, a protective cover 62, and a mounting base 63;

[0057] The protective cover 62 is disposed on the electric hydraulic clamp 61, and the electric hydraulic clamp 61 is disposed on the mounting base 63.

[0058] As can be seen from the above description, the crimping device 6 consists of an electric hydraulic clamp 61, a protective cover 62, and a mounting base 63. It mainly relies on the electric hydraulic clamp 61 to complete the crimping operation, which is easy to control.

[0059] Furthermore, the crimping device 6 also includes an electric push rod 64;

[0060] The movable end of the electric push rod 64 abuts against the pressure relief drive shaft of the electric hydraulic clamp 61.

[0061] As can be seen from the above description, by setting the electric push rod 64 to abut against the pressure relief transmission shaft of the electric hydraulic clamp 61, the automatic pressure relief and reset operation is realized without manual operation, saving time and effort.

[0062] Furthermore, the crimping device 6 also includes a power supply battery 65 and a fixing plate 66;

[0063] The power supply battery 65 is fixed to the workbench via the fixing plate 66 and is electrically connected to the electric hydraulic clamp 61.

[0064] As can be seen from the above description, the electric hydraulic clamp 61 is independently powered by the power supply battery 65, so that it can be independently controlled and can maintain a long working state without external power supply, making it stable and reliable in use.

[0065] Furthermore, clamping block 4 is an elastic element.

[0066] As can be seen from the above description, the clamping block 4 is an elastic element with a certain deformation capacity. While clamping the repair tube, it ensures that the repair tube will not be deformed due to excessive clamping force or other factors, making it convenient to use.

[0067] Furthermore, the first linear drive component 2 is a lead screw module.

[0068] As can be seen from the above description, the first linear drive component 2 is a lead screw module, which controls the movement of the clamping assembly 3 by means of lead screw transmission. Its composition is simple and easy to control.

[0069] Please refer to Figure 7 A method for using a transmission line repair pipe straightening and crimping mechanism, applicable to the aforementioned transmission line repair pipe straightening and crimping mechanism, includes the following steps:

[0070] S1. Start the clamping assembly 3 to clamp and fix the repair tube on the broken wire into the clamping channel 7 of the clamping block 4;

[0071] S2. Simultaneously activate the first linear drive component 2 and the first rotation drive component 5 to control the clamping component 3 to move, so that the clamping block 4 rotates while driving the repair tube to slide on the broken strand of the wire, so as to straighten the wire on one side of the broken strand of the wire.

[0072] S3. After the wire on the other side of the broken strand is straightened, control the repair tube to continue sliding and completely cover the broken strand, and remove the clamping block 4.

[0073] S4. Control the crimping device 6 to crimp the repair tube onto the broken strand of the conductor.

[0074] As can be seen from the above description, the beneficial effects of the present invention are as follows: A clamping assembly 3, a clamping block 4, and a first rotation drive assembly 5 are provided on the guide rail 1. The clamping assembly 3 and the clamping block 4 cooperate to clamp the repair tube on the broken strand of the wire. The first linear drive member 2 and the first rotation drive assembly 5 serve as driving forces to control the clamping block 4 to rotate while driving the repair tube to slide on the broken strand of the wire. This allows the flared mouth 8 to cooperate with the repair tube, straightening and gathering the broken strand at the broken strand into the repair tube. After the straightening operation is completed, the repair tube is pressed and fixed by the crimping device 6, replacing manual operation, reducing the difficulty of straightening and crimping the repair tube, and improving the efficiency of repair tube repair.

[0075] The transmission line repair pipe straightening and crimping mechanism and its usage method of the present invention are applicable to repair pipe repair operations. The following is a detailed description of the specific implementation method:

[0076] Please refer to Figures 1 to 6 Embodiment 1 of the present invention is as follows:

[0077] A transmission line repair pipe straightening and crimping mechanism, such as Figure 1 , Figure 2 and Figure 6As shown, the device includes a worktable and a guide rail 1, a first linear drive 2, a straightening device, and a crimping device 6 located on the worktable. The straightening device includes a clamping assembly 3, a clamping block 4, and a first rotation drive assembly 5. The clamping assembly 3 is slidably mounted on the guide rail 1. The movable end of the first linear drive 2 is connected to the clamping assembly 3, and the direction of movement of the movable end is parallel to the track direction of the guide rail 1. The clamping block 4 is rotatably mounted on the movable end of the clamping assembly 3. The clamping block 4 has a clamping channel 7 for the repair tube to pass through. The clamping channel 7 is parallel to the guide rail 1, and a flared opening 8 is provided at the channel opening of the clamping channel 7. The first rotation drive assembly 5 is drively connected to the clamping block 4 and is used to drive the clamping block 4 to rotate. The crimping interface of the crimping device 6 is located on the same straight line as the clamping channel 7 and is used to crimp the repair tube onto the broken strand of the wire. Furthermore, the clamping block 4 is an elastic element, specifically made of an elastic material such as a rubber block.

[0078] In this embodiment, combined with Figures 1 to 4 As shown, the workbench is also equipped with a broken wire straightening assembly and a second linear drive 9. The broken wire straightening assembly includes a fixed base 10, a wire bundling block 11, and a second rotation drive assembly 12. The fixed base 10 is slidably mounted on the guide rail 1. The movable end of the second linear drive 9 is connected to the fixed base 10, and the direction of movement of the movable end is parallel to the track direction of the guide rail 1. The wire bundling block 11 is rotatably mounted on the fixed base 10. The wire bundling block 11 has a wire through hole 13 for the broken wire to pass through. The wire through hole 13 and the clamping channel 7 are located on the same straight line, and the flared mouth 8 is located on the channel opening of the clamping channel 7 facing the wire through hole 13. The second rotation drive assembly 12 is connected to the wire bundling block 11 for driving the wire bundling block 11 to rotate.

[0079] In this embodiment, as Figure 5 As shown, the straightening device and the broken strand straightening assembly are arranged along the track direction on the guide rail 1. The clamping block 4 on the straightening device is used to drive the repair tube to straighten and gather the broken strands on one side of the broken strand of the broken strand, while the wire-binding block 11 on the broken strand straightening assembly is used to straighten and gather the broken strands on the other side of the broken strand of the broken strand. Furthermore, in order to improve the gathering effect and cooperate with the flared mouth 8, the wire through hole 13 on the wire-binding block 11 is designed with a chamfer at the end facing the flared mouth 8, so that the broken strands can be better gathered from the flared mouth 8 into the clamping channel 7.

[0080] In this embodiment, the first linear drive 2 and the optional second linear drive 9 are lead screw modules. In other equivalent embodiments, linear drive devices such as cylinders can also be used.

[0081] Please refer to Figure 1 and Figure 3 Embodiment two of the present invention is as follows:

[0082] A transmission line repair pipe straightening and crimping mechanism, based on the above-described embodiment one, such as... Figure 1 and Figure 2 As shown, the clamping assembly 3 includes a base and a third linear drive 31, a first splicing plate 32, and a second splicing plate 33 located on the base. The first splicing plate 32 is disposed on the movable end of the third linear drive 31, with the movable end of the third linear drive 31 facing the second splicing plate 33. Both the first splicing plate 32 and the second splicing plate 33 are provided with semi-circular grooves 34. The clamping block 4 includes two sub-clamping blocks 41; each sub-clamping block 41 has a semi-circular edge portion 42 of a size adapted to the semi-circular groove 34. The sub-clamping blocks 41 correspond one-to-one with the semi-circular grooves 34 and are rotatably disposed within the semi-circular grooves 34 through the semi-circular edge portion 42. When the first splicing plate 32 and the second splicing plate 33 are spliced, the two sub-clamping blocks 41 are spliced ​​to form the clamping block 4 and the clamping channel 7, and the two semi-circular grooves 34 are spliced ​​to form a rotation space for the clamping block 4 to rotate.

[0083] In this embodiment, a cam follower is provided on the semi-circular edge 42 of the sub-clamping block 41. The sub-clamping block 41 rotates within the groove track of the semi-circular groove 34 via the cam follower.

[0084] In this embodiment, as Figure 2 As shown, each of the two sub-clamping blocks 41 has a semi-cylindrical through groove. When the two sub-clamping blocks 41 clamp the repair tube, the two through grooves are joined together to form a clamping channel 7.

[0085] In this embodiment, the first rotation drive assembly 5 includes a rotation motor 51, a drive gear 52, and a driven gear 53. The rotation motor 51 is mounted on the clamping assembly 3, the drive gear 52 is mounted on the movable end of the rotation motor 51, and the driven gear 53 is mounted on the clamping block 4. The drive gear 52 and the driven gear 53 are meshed together. Furthermore, as shown in the figure, to correspond to the semi-circular edge 42 of the sub-clamping block 41, the driven gear 53 is also divided into two semi-circular racks, respectively mounted on the first splicing plate 32 and the second splicing plate 33. The positions of the semi-circular racks, the semi-circular groove 34, and the semi-circular edge 42 correspond. Two drive gears 52 and two rotation motors 51 are also correspondingly provided. In this embodiment, the semi-circular racks and the sub-clamping block 41 are detachable, specifically using bolt assembly.

[0086] In this embodiment, as Figure 1 and Figure 3As shown, the clamping assembly 3 and the fixing base 10 have the same structure, both being assembled by splicing. They are arranged opposite each other on the guide rail 1. The wire harness block 11 is also composed of two spliced ​​parts. Correspondingly, the second rotation drive assembly 12 has the same structure as the first rotation drive assembly 5. Since the above structures are similar, they will not be described in detail in this embodiment.

[0087] Please refer to Figure 6 Embodiment 3 of the present invention is as follows:

[0088] A transmission line repair pipe straightening and crimping mechanism, based on the above-described embodiment one, such as... Figure 6 As shown, the crimping device 6 includes an electric hydraulic clamp 61, an electric push rod 64, a protective cover 62, and a mounting base 63; the protective cover 62 is mounted on the electric hydraulic clamp 61, and the electric hydraulic clamp 61 is mounted on the mounting base 63. The movable end of the electric push rod 64 abuts against the pressure relief drive shaft of the electric hydraulic clamp 61.

[0089] In this embodiment, the crimping device 6 is also equipped with an independent power supply, consisting of a power supply battery 65 and a fixing plate 66. The power supply battery 65 is fixed to the workbench via the fixing plate 66 and is electrically connected to the electric hydraulic clamp 61.

[0090] Please refer to Figure 7 Embodiment four of the present invention is as follows:

[0091] A method for using a transmission line repair pipe straightening and crimping mechanism, applicable to a transmission line repair pipe straightening and crimping mechanism in Embodiments 1, 2, or 3 above, includes the following steps:

[0092] S1. Start the clamping assembly 3 to clamp and fix the repair tube on the broken wire into the clamping channel 7 of the clamping block 4;

[0093] In this embodiment, the operation of activating the clamping assembly 3 and subsequent other components can be performed by the maintenance robot.

[0094] S2. Simultaneously activate the first linear drive component 2 and the first rotation drive component 5, control the clamping component 3 to move, so that the clamping block 4 rotates while driving the repair tube to slide on the broken strand of the wire, so as to straighten the wire on one side of the broken strand of the broken strand.

[0095] In this embodiment, when the repair tube is clamped by the clamping block 4, the broken strand of the broken wire is located between the clamping assembly 3 and the fixing base 10. As the clamping block 4 rotates and drives the repair tube to slide along the broken wire toward the wire-binding block 11 of the fixing base 10, the wire-binding block 11 also rotates and moves toward the position of the clamping block 4 under the action of the second linear drive 9 and the second rotational drive, thereby straightening and gathering the wire on the other side of the broken strand. It is worth noting that since the same wire is being straightened, the rotation directions of the clamping block 4 and the wire-binding block 11 are opposite.

[0096] S3. After the wire on the other side of the broken strand is straightened, control the repair tube to continue sliding and completely cover the broken strand, and remove the clamping block 4.

[0097] In this embodiment, when the wire harness block 11 touches the flared end on the clamping block 4, it indicates that the wires on both sides of the broken strand have been straightened and gathered into the space formed by the clamping channel 7, the flared end, and the wire through hole 13. At this time, the second linear drive 9 is driven to make the wire harness block 11 retract, and then the first linear drive 2 is driven to make the clamping block 4 continue to move towards the wire harness block 11. This action is repeated several times until the broken strand of the broken wire falls at the center of the repair tube. Finally, the clamping assembly 3 is released and the clamping block 4 is removed.

[0098] S4. Control the crimping device 6 to crimp the repair tube onto the broken strand of the conductor.

[0099] In this embodiment, the electric hydraulic clamp 61 performs the crimping deformation action after the repair tube is fitted onto the broken strand. It can cooperate with the movement of the maintenance robot to complete the crimping in sequence, and finally fix the repair tube stably and reliably on the broken strand of the conductor.

[0100] In summary, the present invention provides a transmission line repair pipe straightening and crimping mechanism and its usage method. A clamping assembly, a clamping block, and a first rotation drive assembly are arranged on a guide rail. The clamping assembly and clamping block work together to clamp the repair pipe on the broken strand of the conductor. A first linear drive and the first rotation drive assembly provide the driving force, controlling the clamping block to rotate while simultaneously sliding the repair pipe on the broken strand of the conductor. This allows the flared end to engage with the repair pipe, straightening and gathering the broken strands within the repair pipe. After straightening, the repair pipe is crimped and fixed by a crimping device, replacing manual operation, reducing the difficulty of straightening and crimping the repair pipe, and improving the efficiency of repair pipe repair.

[0101] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
