Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction, in particular to a wire threading device used for electric power construction. Background Art

[0002] Power construction refers to the various construction and maintenance activities carried out within power projects, including but not limited to the erection of power lines, construction of substations, and layout of distribution networks. The primary purpose of these activities is to establish and maintain the power supply system to ensure the safe and stable transmission of electrical energy to users. During power construction, cable threading is necessary to protect cables, reduce electrical interference, improve safety, facilitate maintenance, and maintain a clean and tidy construction site. Proper cable threading is crucial to ensuring the safe and reliable operation of the system.

[0003] The existing Chinese patent publication number is CN219998908U, and its name is a "construction power construction pipeline threading device," comprising a fixed hoop, a movable hoop, and a movable hoop movably connected to the end of the fixed hoop. Both the fixed hoop and the movable hoop are semi-annular, and the ends of the outer surfaces of the fixed hoop and the movable hoop are fixedly connected to end plates, which are fixedly connected to each other. Bolts are inserted into the end plates, and nuts are threaded on the bolts. A connecting piece is fixedly connected to one side of the fixed hoop, and the connecting piece is arc-shaped. The end of the connecting piece is fixedly connected to a first joint. Through the coordinated arrangement of the fixed hoop, movable hoop, connecting piece, first joint, spring, second joint, connecting handle, and guide wheel, the cable can be guided smoothly through the pipeline. The cable can be bent into different shapes according to the curvature of the pipeline, thereby guiding the cable through the bend of the pipeline and preventing the cable from getting stuck. This can effectively improve threading efficiency and effectively prevent jamming.

[0004] However, in this technology, the radius of the fixed hoop and the movable hoop is fixed. During use, only wires of one thickness can be clamped and pulled. When the thickness of the wires is different, the threading device needs to be replaced, which makes the threading device less adaptable and inconvenient to use. Therefore, we propose a threading device for power construction to solve the above problems. Utility Model Content

The cam 16 is provided with a plurality of end pieces 19 that are connected to the cam 16. The cam 16 is provided with a plurality of end pieces 17 that are connected to the cam 16. The cam 16 is provided with a plurality of end pieces 18 that are connected to the cam 16. The cam 16 is provided with a plurality of end pieces 19 that are connected to the cam 16.

[0026] In this embodiment, the splint 10 is adhesively connected to the clamping pad 11, and the connecting spring 12 is welded to the outside of the splint 10. The protrusion 15 on the upper connecting plate 13 is arranged above it, and the protrusion 15 on the lower connecting plate 13 is arranged below it. The two slide grooves 19 on the same side are opened at the top and bottom of the mounting groove 8, and the threaded rod 16 is welded and installed on the outer wall of the fixing ring 4. The threaded rod 16 and the block are an integral structure. When it is necessary to adjust the clamping of the wire, the two movable plates 14 on the same side are moved to the relatively far side, or the two movable plates 14 on the same side are moved to the relatively close side according to the width of the wire. When the movable plate 14 moves, it drives the connecting plate 13 to move the splint 10 outward or inward. When the wire is inserted into the outer sleeve 2 from the lower fixing ring 4 until the top of the wire is inserted into the upper fixing ring 4, the two movable plates 14 on the same side are moved to the relatively close side, pushing the connecting plate 13, the protrusion 15 slides in the slide groove 19, and the splint 10 moves toward the wire position until the clamping pads 11 on both sides clamp the wire, the connecting spring 12 is stretched, and the movement of the movable plate 14 is stopped.

Through the setting of the torsion spring 7, when the inner diameter of the wire conduit changes, the bracket 5 is retracted inward, driving the pulley 6 to move to match the inner diameter of the wire conduit. Through the four pulleys 6, traction and guidance are performed during the threading process of the wires. The convex ring 9 is welded to the fixed seat 1. When the threading device moves to the exit position and the pulley 6 is not moved out, the device and the wires can be pulled out by hooking the convex ring 9, which is convenient for use.

When the movable plates 14 move, they drive the connecting plates 13 to move the clamping plates 10 outward or inward. When the wire is inserted into the outer sleeve 2 from the lower fixing ring 4 until the top of the wire is inserted into the upper fixing ring 4, the two movable plates 14 on the same side are moved to the side relatively close to each other, pushing the connecting plates 13. The protrusions 15 slide in the slide grooves 19, and the clamping plates 10 move toward the wire position until the clamping pads 11 on both sides clamp the wire. Tighten, the connecting spring 12 is stretched, and the moving plate 14 stops moving, and the two limit blocks 17 on the threaded rod 16 are rotated to a position close to the moving plate 14, so that the upper limit block 17 is in contact with the upper moving plate 14, and the lower limit block 17 is in contact with the lower moving plate 14, and is used in conjunction with the stop block to limit the two moving plates 14 on the same side to prevent the splint 10 from moving. Then, according to the inner diameter of the wire conduit, the torsion spring 7 is set to retract the bracket 5 inward, driving the pulley 6 to move to match the inner diameter of the wire conduit, and the device is inserted into the wire conduit. Through the four pulleys 6, traction and guidance are performed during the threading of the wires.

[0030] To sum up, the threading device for power construction is used to clamp the wires through the outer sleeve 2, inner spring 3, fixed seat 1, fixed ring 4, clamping device and guide member, so as to perform the threading operation on the wires. The clamping member, connecting spring 12 and adjusting member are provided, so that the wires can be adjusted and clamped according to their width. The device is suitable for wires of various widths. The adaptability of the device is high and it is convenient to use.
