Description

Technical Field

[0001] This utility model belongs to the field of power construction technology, and in particular relates to a cable conveying device for power construction. Background Technology

[0002] In power construction, cable laying and transportation is a crucial step, involving the handling and arrangement of cables from the warehouse to the construction site. Cables are usually coiled into coils for easy laying and transportation at the construction site. The basic structure of a cable consists of four parts: the conductor, the insulation layer, the shielding layer, and the protective layer. Cables are relatively heavy per unit length. When cables are laid out on the ground and transported to cable towers, supports are needed to elevate the cables and reduce the friction they experience. Existing cable transport supports are not very stable and have poor support effects. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the existing technology, the purpose of this utility model is to provide a cable conveying device for power construction, which effectively solves the problem of unstable cable conveying.

[0004] The technical solution to the technical problem is as follows: The machine includes a frame, with adjustment mechanisms at both ends. Each adjustment mechanism includes a screw, threadedly connected to the frame. A support plate is rotatably connected to the lower end of the screw. Guide rods located on both sides of the screw are fixed on the support plate, sliding up and down within the frame. Multiple horizontally arranged first rollers are located below the support plate, with supports at both ends. The first rollers are rotatably connected to the supports. Guide columns are fixed to the upper ends of the supports, sliding up and down within the support plate. Springs are fitted onto the guide columns, located between the supports and the support plate. Multiple horizontally arranged second rollers are evenly installed at the bottom of the frame. Cables pass through the first and second rollers. Limiting devices corresponding to the cables are located at both ends of the frame.

[0005] Preferably, the limiting device includes a positioning plate, which is fixedly connected to the frame. The positioning plate has a through groove in the front-to-back direction. The front and rear sides of the cable are provided with stop bars. The bottom of the stop bars is fixed with bolts, which pass through the through grooves. The bolts are threadedly connected to nuts located at the bottom of the positioning plate.

[0006] Preferably, the frame is provided with an observation port.

[0007] Preferably, a limit block is fixed at the top of the guide post.

[0008] This invention has the following advantages over traditional equipment: it has a clever structure, and the lifting and lowering of the first roller can be adjusted by the adjustment mechanism, making it suitable for cables of various specifications. Under the action of the spring, the first roller has a high buffering effect, which is conducive to the cable passing between the first roller and the second roller. It has a good support effect, reduces cable friction, and has high conveying quality. Under the action of the stop bar, the cable is limited in the front and rear directions, which improves the stability of cable conveying. It is safe and reliable, simple to operate, and economical and practical. Attached Figure Description

[0015] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0016] Depend on Figures 1 to 5 A cable conveying device for power construction is provided, comprising a frame 1, with adjusting mechanisms at both ends of the frame 1. Each adjusting mechanism includes a screw 2, which is threadedly connected to the frame 1. A support plate 3 is rotatably connected to the lower end of the screw 2. Guide rods 4 located on both sides of the screw 2 are fixed on the support plate 3 and slide up and down within the frame 1. Multiple horizontally arranged first rollers 5 are provided below the support plate 3. Supports 6 are provided at both ends of the first rollers 5 and are rotatably connected to the supports 6. Guide columns 7 are fixed at the upper ends of the supports 6 and slide up and down within the support plate 3. Springs 8 are sleeved on the guide columns 7 and are located between the supports 6 and the support plate 3. Multiple horizontally arranged second rollers 9 are evenly installed at the bottom of the frame 1. Cables 10 are threaded between the first rollers 5 and the second rollers 9. Limiting devices corresponding to the cables 10 are provided at both ends of the frame 1.

[0017] To facilitate adjustment of the distance between the two stop bars 13 and to accommodate cables 10 of different specifications, the limiting device includes a positioning plate 11, which is fixedly connected to the frame 1. The positioning plate 11 has a through groove 12 in the front-to-back direction. Stop bars 13 are provided on the front and rear sides of the cable 10. Bolts are fixed at the bottom of the stop bars 13, and the bolts pass through the through groove 12. The bolts are threadedly connected to nuts 14 located at the bottom of the positioning plate 11.

[0018] In order to reduce the weight of the frame 1 and facilitate observation of the cable 10 conveying inside the frame 1, an observation port 15 is provided inside the frame 1.

[0019] To prevent the guide post 7 from detaching from the support plate 3, a limit block 16 is fixed at the top of the guide post 7.

[0020] In use, the power cable 10 passes between the first roller 5 and the second roller 9. The adjustment mechanism raises and lowers the cable 10 according to its specifications. The screw 2 rotates within the frame 1 via its internal thread. The screw 2 is rotatably connected to the support plate 3. The screw 2 drives the support plate 3 to slide up and down along the guide rod 4. The support plate 3 drives the guide column 7, the bracket 6, and the first roller 5 to move up and down as a whole, causing the first roller 5 and the second roller 9 to simultaneously contact the cable 10. A spring 8 is fitted on the guide column 7, located between the bracket 6 and the support plate 3, providing a certain degree of vertical buffering for the first roller 5, effectively protecting the surface of the cable 10. The threaded connection is self-locking, simple to operate, and safe and stable.

[0021] The limiting device can limit the cable 10 in the front and rear directions to prevent the cable 10 from detaching from the frame 1 during the transportation process. Loosen the nut 14, and the bolt moves in the front and rear directions in the through groove 12, thereby adjusting the front and rear position of the stop bar 13. Then tighten the nut 14 to limit the stop bar 13. There are stop bars 13 on both the front and rear sides of the cable 10, which is convenient, quick, low cost, economical and practical. The frame 1 can be installed on a trolley or motor vehicle to improve the flexibility of the frame 1 and facilitate the transportation of the cable 10 during power construction.

[0022] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
