Description

Technical Field

[0001] This utility model relates to the field of cable installation technology, specifically a cable stabilization and guiding device for power line overhead construction. Background Technology

[0002] Integrated utility tunnels are underground tunnel structures built in cities to centrally lay municipal pipelines such as electricity, communications, water supply, heating, and gas, and are hailed as the "main artery of the city's lifeline." Through unified planning, construction, and management, they systematically accommodate various pipelines that were originally buried or overhead, completely solving the problems of repeated road excavation, wasted space resources, and frequent pipeline accidents caused by traditional pipeline laying methods, and greatly improving the carrying capacity of urban infrastructure.

[0003] On the inner walls of the integrated utility tunnel, cable racks are specially installed for fixing and supporting cables. These cable racks are designed to ensure that cables can be installed orderly and safely within the tunnel's interior space. However, it is worth noting that some cable racks are installed at a certain height above the ground. While this design facilitates cable layout and maintenance, it can cause inconvenience in actual operation, especially when installing larger diameter and heavier cables. Therefore, a cable stabilization and guiding device for power line overhead line construction is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a stable guiding device for cables during power line construction to solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable stabilization and guiding device for power line overhead line construction, comprising a comprehensive utility tunnel, a cable rack fixedly installed on the side wall of the comprehensive utility tunnel, an equipment frame provided inside the comprehensive utility tunnel, a lifting mechanism installed on the equipment frame, the lifting mechanism comprising two positioning shafts fixedly installed on the equipment frame, a lower support arm rotatably installed on each of the two positioning shafts, a first connecting seat and a second connecting seat rotatably connected to the end of the lower support arm respectively, a first screw connecting the first connecting seat and the second connecting seat, an upper support arm rotatably installed at the end of each of the first and second connecting seats, a positioning seat rotatably installed at the end of the upper support arm, and a guiding mechanism installed on the positioning seat.

[0006] Preferably, the lifting mechanism further includes a lifting frame slidably mounted on the positioning seat and a second screw threadedly mounted on the bottom of the positioning seat. A guide roller is rotatably mounted inside the lifting frame, and the upper end of the second screw is rotatably mounted on the lifting frame.

[0007] Preferably, the positioning seat is provided with a rotating shaft, and the upper support arm is rotatably mounted on the positioning seat via the rotating shaft.

[0008] Preferably, the lower support arm is rotatably mounted on the equipment frame via a positioning shaft, one end of the first screw is rotatably mounted on the first connecting seat, the second connecting seat has a screw hole, and the first screw is threadedly connected to the second connecting seat.

[0009] Preferably, the guiding mechanism includes a mounting bracket and a housing fixedly mounted on the positioning seat. A threaded conveying roller is rotatably mounted on the mounting bracket. A planetary reducer is fixedly mounted inside the housing. A movable shaft is rotatably mounted on the housing. A pinion is fixedly mounted at one end of the movable shaft, and a sprocket is fixedly mounted at the other end of the movable shaft. A chain is connected to the sprocket.

[0010] Preferably, the output end of the planetary reducer is fixedly mounted on one end of the threaded conveyor roller, and a large gear is fixedly mounted on the input end of the planetary reducer.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a stable cable guiding device for power line overhead line construction. It includes a utility tunnel 1, a cable rack 2 fixedly installed on the side wall of the utility tunnel 1, an equipment frame 3 inside the utility tunnel 1, a lifting mechanism 4 installed on the equipment frame 3, and a guiding mechanism 5 installed on the positioning seat 407. The lifting mechanism 4 can lift the cable to one end height, and after the cable is lifted to one end height, the guiding mechanism 5 can push the cable onto the cable rack 2, achieving rapid cable installation.

[0017] Example 1: As Figure 2 , Figure 3 and Figure 4 As shown, the lifting mechanism 4 includes two positioning shafts 401 fixedly installed on the equipment frame 3. A lower support arm 402 is rotatably installed on each of the two positioning shafts 401. A first connecting seat 403 and a second connecting seat 409 are rotatably connected to the ends of the lower support arms 402, respectively. A first screw 408 is connected between the first connecting seat 403 and the second connecting seat 409. An upper support arm 404 is rotatably installed at the ends of the first connecting seat 403 and the second connecting seat 409. A positioning seat 407 is rotatably installed at the end of the upper support arm 404. The lifting mechanism 4 also includes a lifting frame 406 slidably installed on the positioning seat 407 and a second screw 410 threadedly installed at the bottom of the positioning seat 407. A guide roller 405 is rotatably installed inside the lifting frame 406, and the upper end of the second screw 410 is rotatably installed on the lifting frame 406. A rotating shaft is provided on the positioning seat 407, and the upper support arm 404 is rotatably installed on the positioning seat 407 through the rotating shaft.

[0018] Specifically, rotating the first screw 408 brings the first connecting seat 403 and the second connecting seat 409 closer together, thereby causing the upper support arm 404 and the lower support arm 402 to close. When the upper support arm 404 and the lower support arm 402 close, the positioning seat 407 moves upward, thereby lifting the cable to the installation position. After the cable is lifted to the installation position, rotating the second screw 410 causes the guide roller 405 on the lifting frame 406 to retract into the positioning seat 407.

[0019] Example 2: Figure 2 and Figure 5 As shown, the guide mechanism 5 includes a mounting frame 501 and a housing 504 fixedly mounted on the positioning seat 407. A threaded conveying roller 502 is rotatably mounted on the mounting frame 501. A planetary reducer 503 is fixedly mounted inside the housing 504. A movable shaft 506 is rotatably mounted on the housing 504. A pinion 507 is fixedly mounted at one end of the movable shaft 506, and a sprocket 505 is fixedly mounted at the other end of the movable shaft 506. A chain 509 is connected to the sprocket 505. The output end of the planetary reducer 503 is fixedly mounted on one end of the threaded conveying roller 502. A large gear 508 is fixedly mounted on the input end of the planetary reducer 503. Bearings are mounted on both the mounting frame 501 and the housing 504. The threaded conveying roller 502 is rotatably mounted on the mounting frame 501 via the bearings, and the movable shaft 506 is rotatably mounted on the housing 504 via the bearings.

[0020] Specifically, after the cable falls onto the threaded conveyor roller 502, it pulls the chain 509. The chain 509, when pulled, drives the sprocket 505 to rotate. The rotation of the sprocket 505, in turn, drives the movable shaft 506 to rotate. The rotation of the movable shaft 506 drives the pinion 507 to rotate. The rotation of the pinion 507, in turn, drives the large gear 508 to rotate. The rotation of the large gear 508 ultimately drives the threaded conveyor roller 502 to rotate. During the rotation of the threaded conveyor roller 502, its threaded mechanism pushes the cable forward, thus smoothly transferring the cable to the cable holder 2, achieving rapid cable installation.

[0021] Working principle: In operation, the entire equipment is first set up within the integrated utility tunnel 1. Then, the cable is pulled along the guide roller 405 to slide, thus placing the cable within the integrated utility tunnel 1. After the cable is placed, the first screw 408 is rotated. Rotating the first screw 408 brings the first connecting seat 403 and the second connecting seat 409 closer together, causing the upper support arm 404 and the lower support arm 402 to close. Once the upper and lower support arms 404 and 402 are closed, the positioning seat 407 moves upward, lifting the cable to the installation position. After the cable is lifted to the installation position, the second screw 410 is rotated. Rotating the second screw 410 causes the guide roller 405 on the lifting frame 406 to retract into the positioning seat 407. The cable falls onto the threaded conveyor roller 502. Once the cable is on the threaded conveyor roller 502, the chain 509 can be pulled. Pulling the chain 509 will drive the sprocket 505 to rotate. The rotation of the sprocket 505 will drive the movable shaft 506 to rotate. The rotation of the movable shaft 506 will drive the pinion 507 to rotate. The rotation of the pinion 507 will drive the large gear 508 to rotate. The rotation of the large gear 508 will drive the threaded conveyor roller 502 to rotate. When the threaded conveyor roller 502 rotates, the threaded mechanism on it will push the cable forward, thereby pushing the cable onto the cable rack 2, realizing the rapid installation of the cable.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
