Description

Technical Field

[0001] This utility model relates to the field of cable pulling tools, and in particular to a cable guiding mechanism. Background Technology

[0002] During the installation of high-voltage power lines between angle steel towers, guiding structures are required to direct the cable installation. This is primarily to ensure the high-voltage lines maintain the correct path during installation and prevent line faults due to positional deviations. For example, in transmission line construction, guiding devices help fix the cable position and prevent line deviation due to wind or construction errors. Many related traction structures exist in existing technology.

[0003] For example, Chinese Patent Application No. 202320003139.6 discloses a novel locking pin installation tool, including a housing, a guide wire, and a locking pin. The guide wire includes a guide ring, a connecting rod fixedly connected to the bottom of the guide ring, and a limiting block fixedly connected to the bottom of the connecting rod. The housing has an internal receiving groove for the limiting block to enter, and a through groove connected to the receiving groove is provided on the top of the housing. The connecting rod passes through the through groove. The guide wire passes through the receiving groove via the limiting block, and the connecting rod passes through the through groove to connect with the housing.

[0004] Although the existing tool makes the conductor structure less prone to loosening, the stability of the traction position adjustment is not high, and the compactness of the structure is not good enough, resulting in a large degree of loosening. In the long-term use process, such as in windy weather, the wires may cause the conductors to deflect violently, which can easily lead to various wear and tear and instability in the installation between structures.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.

[0025] Examples, such as Figure 1-6As shown, a cable guiding mechanism includes a supporting housing 1 and a cable guiding bracket mounted on the supporting housing 1. The supporting housing 1 is hollow, forming an internal cavity 10. Both the supporting housing 1 and the cable guiding bracket can be made of metal components such as stainless steel. The cable guiding bracket is used to guide high-voltage lines. Specifically, the cable guiding bracket includes a guiding ring 21 located above the supporting housing 1 for guiding the cable, a connecting rod 22 integrally connected to the lower part of the guiding ring 21, extending downward through the supporting housing 1 and into the internal cavity 10, and a limiting block 23 integrally connected to the lower end of the connecting rod 22, which is confined within the supporting housing 1. The limiting block 23 is also within the internal cavity 10 and mutually confines the internal cavity 10 and the supporting housing 1, preventing the cable guiding bracket from detaching from the supporting housing 1. The most significant feature of this application is that the limiting block 23 is elastically supported within the supporting housing 1. This elastic support allows the limiting block 23 to maintain better adhesion to the supporting housing 1, thus preventing the cable guiding bracket from shifting or loosening, resulting in better stability and safer use.

[0026] Specifically, the supporting shell 1 includes an upper plate 11, a left plate 12, a lower plate 13, and a right plate 14 that are integrally connected from top to bottom and right to bottom, and a front plate 15 that is integrally connected to the front surfaces of the upper plate 11, left plate 12, lower plate 13, and right plate 14, thus forming a semi-enclosed structure. The upper plate 11, left plate 12, lower plate 13, right plate 14, and front plate 15 enclose and form the internal cavity 10. The rear side of the internal cavity 10 serves as an inlet for the connecting rod 22 and the limiting block 2. 3. Entering from back to front: Because there is no enclosed structure on the rear side, entry is convenient. The bottom of the limiting block 23 is fixed with a downward-extending support spring 3 for elastic support. The lower end of the support spring 3 can directly abut against the upper side of the lower plate 13, thus allowing the limiting block 23 to elastically support and adhere tightly to the lower side of the upper plate 11. The preload force prevents the limiting block 23 from deflecting, thereby ensuring the stability of the upper guide ring 21. Since the guide ring 21 is the structure through which the high-voltage line passes directly, the position of the high-voltage line is also more stable. Of course, the lower end of the support spring 3 can be connected to other structures to support the lower plate 13 for even better results, as detailed below:

[0027] The lower end of the support spring 3 is fixed with a bottom ball 31 that allows it to rotate and is supported on the lower side of the lower plate 13. The bottom ball 31 can be made of steel ball. The upper and lower ends of the support spring 3 can be fixed to the limiting block 23 and the bottom ball 31 respectively by welding. The bottom ball bearing 31 is designed to facilitate the adjustment of the guide ring 21's angle. During the installation of the high-voltage line, its structure needs to be connected with the angle steel tower, and the direction of the high-voltage line is also determined by the site conditions. Therefore, the direction of the guide ring 21 needs to be easily adjustable during assembly, while ensuring stability after adjustment. The above structural design is very suitable. When the angle needs to be adjusted in the early stage, the guide ring 21 is pressed down slightly, the support spring 3 is compressed, and the limit block 23 will also move down and not be in close contact with the upper plate 11 for easy rotation. The bottom ball bearing 31 on the lower side is also easy to rotate, and the connecting rod 22 is also designed to be cylindrical for easy rotation. Thus, the guide ring 21 is pressed down to facilitate rotation and angle adjustment. After the angle is adjusted, the guide ring 21 is released to allow it to automatically return to its upward position. The rebound of the support spring 3 allows the limit block 23 to be in close contact with the lower side of the upper plate 11, thereby ensuring stability after adjustment. Of course, the support spring 3 is always kept in a compressed state with elastic force.

[0028] Preferably, the limiting block 23 includes a frustum portion 231 and a cylindrical portion 232 that are integrally connected. The top of the frustum portion 231 is integrally connected to the bottom of the connecting rod 22, and the bottom of the cylindrical portion 232 is fixedly connected to the upper end of the support spring 3. The frustum portion 231 is actually used for limiting, while the cylindrical portion 232 plays a supporting and reinforcing role.

[0029] Furthermore, the upper plate 11 has a support and positioning hole 110 that runs vertically through the connecting rod 22 for vertical passage. The lower surface of the upper plate 11 forms a frustum limiting groove 111 that matches the shape of the frustum portion 231. The upper plate 11 also has a front and rear guide channel 1101 that extends from back to front, runs vertically through the upper plate, and communicates with the support and positioning hole 110 for the connecting rod 22 to move back and forth. This structural design facilitates assembly and provides better positioning. During back-to-front assembly, the left and right widths of the front and rear guide channels 1101 remain relatively constant. The diameter of the upper connecting rod 22 is the same as or slightly larger than that of the upper connecting rod 22, but definitely smaller than the left and right dimensions of the limiting block and the guide ring 21. Thus, the lower portion of the limiting block and the lower part of the connecting rod 22 enters the internal cavity 10 from the rear inlet. The middle main body of the connecting rod 22 moves forward from the front and rear guide channels 1101 and finally reaches the support positioning hole 110. The guide ring 21, located above the upper plate, moves forward along with it to the designated position. The frustum-shaped limiting groove 111 is directly below the support positioning hole 110 and the two are vertically connected. Both the frustum-shaped limiting groove 111 and the support positioning hole 110 are located in the middle of the front and rear of the supporting housing 1. Due to the elastic structure, the entire structure needs to be pushed forward. The length of the connecting rod 22 needs to ensure sufficient margin so that the guide ring 21 does not press down on the upper plate 11, causing obstruction to its movement.

[0030] Specifically, a rear extension guide plate 16 extending to the right is integrally connected to the rear side of the lower plate 13. The upper surfaces of the lower plate 13 and the rear extension guide plate 16 form a continuous front and rear guide groove 136 for supporting and moving the bottom ball bearing 31. The front and rear guide groove 136 has an arc-shaped cross-section. This design facilitates forward assembly and allows for elastic up and down expansion. During assembly, the guide ring 21 presses down with the connecting rod 22 and the limiting block. The bottom ball bearing 31 is in the front and rear guide groove 136, and the support spring 3 is compressed. This causes the bottom ball bearing 31, the support spring 3, the limiting block, and part of the connecting rod to enter the central area of ​​the internal cavity 10 from the rear inlet. The connecting rod moves forward from the front and rear guide channel 1101 and also enters the central area. Then, the support spring 3 is no longer pressed down, and the support spring 3 expands. The limiting block can then be engaged in the frustum limiting groove 111 to achieve limiting and elastic support.

[0031] To ensure the stability of the limiting block, especially the entire cable guide bracket, after entering the center, a limiting structure is needed on the lower side. Specifically, the internal cavity 10 is equipped with a lower limiting connector that can be inserted from its rear inlet to limit the lower side of the cylindrical part 232, thus eliminating the possibility of the limiting block deflecting vertically. This ensures that the limiting block itself is more stable, thereby making the cable guide bracket more stable. The lower limiting connector can also be made of metal such as steel.

[0032] Specifically, the lower limiting connector includes a left limiting plate 41 and a right limiting plate 42 extending forward and backward and spaced apart left and right, and a rear reinforcing connecting plate 43 connecting the rear parts of the left limiting plate 41 and the right limiting plate 42. The gap between the left limiting plate 41 and the right limiting plate 42 is used for the insertion of the support spring 3 and the bottom ball bearing 31. The left limiting plate 41 and the right limiting plate 42 are located below the limiting block and are as close as possible to the lower side of the limiting block, so that the limiting effect is better. The lower limiting connector is inserted forward after the cable guide bracket and spring and other structures have entered the central area. The projection of the left limiting plate 41 and the right limiting plate 42 in the vertical direction with the cylindrical part 232 is at least partially overlapping, that is, directly below, so that it can truly play a limiting role.

[0033] Furthermore, the left plate 12, right plate 14, left limiting plate 41, and right limiting plate 42 are connected and fixed by transverse connecting bolts 401 extending to the left and right through these four. Each of the left plate 12, right plate 14, left limiting plate 41, and right limiting plate 42 has corresponding transverse mounting holes 400 for the transverse connecting bolts 401 to pass through. This ensures the stability of the position and the stability of the entire structure after the lower limiting connector is inserted forward into the internal cavity 10. Of course, a nut 402 is also required for the transverse connecting bolt 401. The two are used together to connect the four together.

[0034] Preferably, the lower surface of the lower plate 13 is connected to a connecting assembly for connecting with the angle steel tower. The connecting assembly can employ an existing structure. For example, the lower surface of the lower plate 13 may be integrally connected with a left base plate 51 and a right base plate 52 spaced apart, along with bottom bolts 53 passing through the left and right base plates 51 and 52. Thus, the left and right base plates 51 and 52 are mounted on corresponding parts of the angle steel tower and then connected and sealed using the bottom bolts 53. Nuts are generally also required. Of course, other existing connecting structures can also be used to connect the connecting assembly to the angle steel tower.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
