[0002] Wind energy is a renewable, pollution-free, high-energy, and broad-prospect energy source. Vigorously developing wind power, a clean energy source, has become a strategic choice for countries around the world and is also an important direction for the development of renewable energy. Therefore, the development and utilization of renewable energy, especially the development and utilization of wind energy, have received great attention from countries around the world. A wind turbine is the core device of wind power generation. To prevent the cables of the wind turbine from being worn, a corrugated pipe is usually sleeved outside the cables. As time goes by, the cables will become loose, and it is necessary to axially compress the corrugated pipe so that the ends of the cables are exposed outside the corrugated pipe, thereby re-crimping the ends of the cables. However, currently, the corrugated pipe is generally compressed manually, which is time-consuming and laborious and affects the working efficiency of corrugated pipe compression.

[0032] Refer to Figure 1 and Figure 2, in an embodiment of the present application, a compression tooling 10 is provided for compressing a corrugated pipe 20 sleeved with a cable, so as to shorten the length of the corrugated pipe 20, so that the end of the cable can be exposed from the corrugated pipe 20 for crimping. The corrugated pipe 20 includes a plurality of convex rings 21 arranged at intervals along the axial direction of the corrugated pipe 20, and an annular groove 22 is formed between any two adjacent convex rings 21. The compression tooling 10 includes a support assembly 100, a guiding assembly 200, and a compression assembly 300. The support assembly 100 and the compression assembly 300 are connected through the guiding assembly 200.

[0033] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , in some embodiments, a support hole 140 is formed on the support assembly 100. The support assembly 100 includes a support ring 130 protruding radially from the inner wall surface of the support hole 140 along the support hole 140. The support ring 130 is used to cooperate with the annular groove 22 on the corrugated pipe 20, so that the support ring 130 abuts axially on the corrugated pipe 20 between two convex rings 21. In this way, the support ring 130 can limit the corrugated pipe 20 axially along the corrugated pipe 20.

[0034] The support assembly 100 includes a first support block 110 and a second support block 120. The first support block 110 and the second support block 120 are detachably connected. The first support block 110 includes a first support body 111 and a first support protrusion 112. A first support arc-shaped hole 1111 is formed on the first support body 111. The first support protrusion 112 protrudes from the inner wall surface of the first support arc-shaped hole 1111. The first support arc-shaped hole 1111 can be a semi-circular hole or the like. The second support block 120 includes a second support body 121 and a second support protrusion 122. A second support arc-shaped hole 1211 is formed on the second support body 121. The second support protrusion 122 protrudes from the inner wall surface of the second support arc-shaped hole 1211. The second support arc-shaped hole 1211 can be a semi-circular hole or the like. When the first support block 110 and the second support block 120 are connected, the first support arc-shaped hole 1111 and the second support arc-shaped hole 1211 are spliced to form a closed-loop support hole 140. The corrugated pipe 20 is inserted into the support hole 140, and the inner wall surface of the support hole 140 can abut against the outer surface of the convex ring 21 on the corrugated pipe 20 radially along the support hole 140. The first support protrusion 112 and the second support protrusion 122 will be spliced to form a closed-loop support ring 130. By detachably connecting the first support block 110 and the second support block 120, interference can be eliminated, so that the first support protrusion 112 and the second support protrusion 122 can cooperate with the annular groove 22 of the corrugated pipe 20.

[0035] The first support block 110 is provided with a support positioning hole 113. The second support block 120 includes a support convex post 123. The support convex post 123 is protrudingly arranged on the second support body 121 along the axial direction of the guide rod 210. When the first support block 110 and the second support block 120 are spliced with each other, the support convex post 123 cooperates with the support positioning hole 113, so as to preliminarily position the first support block 110 and the second support block 120. The first support block 110 is further provided with a first support connection hole 114, and the second support block 120 is further provided with a second support connection hole 124. The center lines of the first support connection hole 114 and the second support connection hole 124 both extend along a direction perpendicular to the axial direction of the guide rod 210. After the support convex post 123 and the support positioning hole 113 cooperate with each other to preliminarily position the first support block 110 and the second support block 120, fasteners such as bolts can be inserted into the first support connection hole 114 and the second support connection hole 124, so as to fix the spliced first support block 110 and second support block 120. At this time, in view of the fact that the support ring 130 cooperates with the annular groove 22 of the corrugated pipe 20 and abuts between the two convex rings 21, when an axial force is applied to the corrugated pipe 20 along the axial direction of the corrugated pipe 20, the corrugated pipe 20 cannot break away from the support hole 140. Therefore, the entire support assembly 100 can position the corrugated pipe 20 axially and radially.

[0036] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , in some embodiments, the compression assembly 300 is provided with a compression hole 340. The compression assembly 300 includes a compression ring 330 protrudingly arranged on the inner wall surface of the compression hole 340 along the radial direction of the compression hole 340. The compression ring 330 is used to cooperate with the annular groove 22 on the corrugated pipe 20, so that the compression ring 330 axially abuts between the two convex rings 21 on the corrugated pipe 20. In this way, the compression ring 330 can limit the corrugated pipe 20 axially along the axial direction of the corrugated pipe 20.

[0037] The compression assembly 300 includes a first compression block 310 and a second compression block 320, which are detachably connected. The first compression block 310 includes a first compression body 311 and a first compression protrusion 312. The first compression body 311 is provided with a first compression arc hole 3111, and the first compression protrusion 312 is protrudingly arranged on the inner wall surface of the first compression arc hole 3111. The first compression arc hole 3111 may be a semicircular hole, etc. The second compression block 320 includes a second compression body 321 and a second compression protrusion 322. The second compression body 321 is provided with a second compression arc hole 3211, and the second compression protrusion 322 is protrudingly arranged on the inner wall surface of the second compression arc hole 3211. The second compression arc hole 3211 may be a semicircular hole, etc. When the first compression block 310 and the second compression block 320 are connected, the first compression arc hole 3111 and the second compression arc hole 3211 are spliced ​​to form a closed-loop compression hole 340, and the bellows 20 is inserted into the compression hole 340. The inner wall surface of the compression hole 340 can abut against the outer surface of the convex ring 21 on the bellows 20 along the radial direction of the compression hole 340. The first compression protrusion 312 and the second compression protrusion 322 are spliced ​​to form a closed-loop compression ring 330. By detachably connecting the first compression block 310 and the second compression block 320, interference can be eliminated so that the first compression protrusion 312 and the second compression protrusion 322 cooperate with the annular groove 22 of the bellows 20.

[0038] The first compression block 310 is provided with a compression positioning hole 313, and the second compression block 320 includes a compression boss 323, which is provided on the second compression body 321 along the axial direction of the guide rod 210. When the first compression block 310 and the second compression block 320 are spliced ​​with each other, the compression boss 323 cooperates with the compression positioning hole 313, thereby preliminarily positioning the first compression block 310 and the second compression block 320. The first compression block 310 is also provided with a first compression connection hole 314, and the second compression block 320 is also provided with a second compression connection hole 324. The center lines of the first compression connection hole 314 and the second compression connection hole 324 both extend perpendicular to the axial direction of the guide rod 210. After the compression boss 323 cooperates with the compression positioning hole 313 to preliminarily position the first compression block 310 and the second compression block 320, fasteners such as bolts can be inserted into the first compression connection hole 314 and the second compression connection hole 324 to fix the spliced ​​first compression block 310 and the second compression block 320. At this time, since the compression ring 330 cooperates with the annular groove 22 of the bellows 20 and abuts between the two convex rings 21, when a force is applied to the bellows 20 along the axial direction of the bellows 20, the bellows 20 will not be able to escape from the compression hole 340, so the entire compression assembly 300 can position the bellows 20 axially and radially.

[0039] See also Figure 1 ,Figure 2 , Figure 3 and Figure 4 , in some embodiments, the first compression block 310 further includes a first handle 315, and the first handle 315 is connected to the first compression body 311; the second compression block 320 further includes a second handle 325, and the second handle 325 is connected to the second compression body 321. By gripping the first handle 315 and the second handle 325, it is convenient to operate the entire first compression block 310 and the second compression block 320, thereby improving the splicing efficiency between the first compression block 310 and the second compression block 320.

[0040] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , in some embodiments, the guiding assembly 200 may include guiding rods 210. The number of the guiding rods 210 may be multiple. One end of the guiding rod 210 is fixedly connected to the supporting assembly 100, and the guiding rod 210 passes through the compression assembly 300, such that the compression assembly 300 can slide relatively close to or away from the supporting assembly 100 along the guiding rod 210. The number of the guiding rods 210 may be an even number. Half of the guiding rods 210 are arranged on the first supporting block 110 and slidably pass through the first compression block 310, and the other half of the guiding rods 210 are arranged on the second supporting block 120 and slidably pass through the second compression block 320. By providing the guiding rods 210, the sliding accuracy of the compression assembly 300 relative to the supporting assembly 100 can be improved.

[0041] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, when it is necessary to compress the bellows 20 with the compression tooling 10, the bellows 20 can be first placed in the first support arc hole 1111 and the second support arc hole 1211, and then the first support block 110 and the second support block 120 are spliced and fixed so that the first support protrusion 112 and the second support protrusion 122 cooperate with the annular groove 22 of the bellows 20 and abut between the two convex rings 21. Then the bellows 20 is placed in the first compression arc hole 3111 and the second compression arc hole 3211, and then the first compression block 310 and the second compression block 320 are spliced and fixed so that the first compression protrusion 312 and the second compression protrusion 322 cooperate with the annular groove 22 of the bellows 20 and abut between the two convex rings 21. Then the entire compression assembly 300 is slid along the guide rod 210 close to the support assembly 100, so that the width of the annular groove 22 on the bellows 20 and the distance between the two convex rings 21 can be reduced, thereby axially compressing the bellows 20 to reduce the length of the bellows 20. By setting the compression tooling 10 to replace the extensive manual operation, the working efficiency of compressing the bellows 20 can be greatly improved.

[0042] In some embodiments, a plurality of limiting holes 211 are further formed on the guide rod 210. The plurality of limiting holes 211 are arranged at intervals along the axial direction of the guide rod 210. A limiting member is used to pass through the limiting holes 211, and the limiting member is used to abut against the compression assembly 300 along the axial direction of the guide post. During the process of compressing the bellows 20, after the bellows 20 is compressed to a certain extent, the limiting member can be passed through the limiting hole 211, so that the limiting member applies a abutting force towards the support assembly 100 to the compression assembly 300, so that the compression assembly 300 stays at a preset position on the guide rod 210, and there is no need to hold the compression assembly 300 manually, thereby improving the convenience of operating the compression tooling 10.

[0043] In some embodiments, the compression tooling 10 further includes a first arc-shaped tube 410 and a second arc-shaped tube 420. The first arc-shaped tube 410 and the second arc-shaped tube 420 are located between the support assembly 100 and the compression assembly 300. The first arc-shaped tube 410 protrudes and is provided on the first support block 110, such that the end of the first arc-shaped tube 410 is fixedly connected to the first support block 110. The second arc-shaped tube 420 protrudes and is provided on the second support block 120, such that the end of the second arc-shaped tube 420 is fixedly connected to the second support block 120. The spliced first arc-shaped tube 410 and second arc-shaped tube 420 enclose a limiting lumen 430, and the limiting lumen 430 is used for passing through the bellows 20. After the support assembly 100 is assembled, the first arc-shaped tube 410 and the second arc-shaped tube 420 will enclose the limiting lumen 430, such that the bellows 20 is passed through the limiting lumen 430. During the process that the compression assembly 300 slides close to the support assembly 100 to compress the bellows 20, the limiting lumen 430 will always exert a limiting effect on the bellows 20, which can effectively prevent the bellows 20 from bending during the compression process and further improve the operation convenience of the compression tooling 10.

[0044] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0045] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
