Technical Field

[0001] This utility model relates to the field of line splitter technology, specifically a line splitter for power engineering overhead line construction. Background Technology

[0002] Electric power engineering refers to engineering related to the production, transmission, and distribution of electrical energy. In a broader sense, it also includes engineering that uses electricity as a power source and energy source in various fields. It can also be understood as power transmission and transformation expansion engineering. Stringing construction is the final stage of transmission line construction engineering and the main process in overhead transmission line construction. Its task is to erect the conductors and lightning protection wires on the assembled towers according to the designed stringing stress.

[0003] During the laying of power lines, different wires are often installed. It is necessary to separate these wires during the installation process to facilitate subsequent organization and laying. Since the wires are of varying thicknesses, the branch channels for the branch channels also need to be changed accordingly. Changing the branch channels based on the wire diameter during construction can be quite cumbersome. Therefore, we propose a branch channel device for power line installation to address these issues.

[0022] 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.

[0023] Please see Figure 1-4An embodiment of this utility model provides a power line splitter for overhead line construction, comprising a lower support rod seat 6 and a fixed base 12. An upper support rod 1 is inserted into the top of the lower support rod seat 6. An upper support crossbar 4 is inserted inside the upper support rod 1. An upper splitting pulley 3 is installed on the outside of the upper support crossbar 4. A telescopic groove 18 is opened inside the upper support rod 1. A movable crossbar 9 is inserted inside the telescopic groove 18. Telescopic springs 14 are connected to the bottom of both sides of the movable crossbar 9. A lower splitting pulley 5 is sleeved on the outside of the movable crossbar 9.

[0024] Multiple sets of upper dividing line pulleys 3 and lower dividing line pulleys 5 are provided. The upper dividing line pulleys 3 and lower dividing line pulleys 5 are sequentially sleeved on the outside of the upper support crossbeam 4 and the movable crossbar 9. The upper support crossbeam 4 is fixed to the top of the fixed base 12 by connecting with the upper support rod 1. The two sides of the movable crossbar 9 are inserted into the telescopic grooves 18 opened inside the upper support rod 1 and connected to the telescopic springs 14. The movable crossbar 9 extends and retracts inside the telescopic grooves 18 by the telescopic springs 14.

[0025] Specifically, such as Figure 1 and Figure 2 As shown, by setting an adaptive separation structure, during use, one end of the wire outside the limiting cover 7 is pulled out, and then the movable crossbar 9 is stretched inside the telescopic grooves 18 on both sides of the upper support rod 1 by the telescopic spring 14. The wire is placed between the upper wire separating pulley 3 and the lower wire separating pulley 5. The movable crossbar 9 rebounds inside the telescopic groove 18 by the telescopic spring 14, causing the lower wire separating pulley 5 outside the movable crossbar 9 and the lower wire separating pulley 5 outside the upper support crossbar 4 to clamp the wire. When the wire moves inside the upper wire separating pulley 3 and the lower wire separating pulley 5, the upper wire separating pulley 3 and the lower wire separating pulley 5 will rotate outside the upper support crossbar 4 and the movable crossbar 9 respectively, thereby realizing the adaptive separation function.

[0026] A support frame 8 is installed on the top of the fixed base 12. The bottom front and rear ends of the support frame 8 are provided with snap-fit ​​blocks 19. The front end of the fixed base 12 is provided with a sliding groove 11. A connecting screw 20 is inserted into the sliding groove 11. A locking block 10 is sleeved on the outside of the connecting screw 20.

[0027] The snap-fit ​​block 19 at the front end of the support frame 8 snaps into the inside of the fixed base 12. The support frame 8 slides with the fixed base 12 and the sliding groove 11 inside the fixed base 12 through the snap-fit ​​block 19 and the connecting screw 20. The connecting screw 20 passes through the sliding groove 11 inside the support frame 8 and the fixed base 12. The locking block 10 is sleeved on the outside of the connecting screw 20 and contacts the front and rear ends of the fixed base 12.

[0028] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, by setting a sliding adjustment structure, when in use, after the wires of different widths are sleeved on the outside of the limiting cover 7 of different widths, the support frame 8 is slid inside the fixed base 12 through the snap-fit ​​block 19, which drives the connecting screw 20 inserted inside the support frame 8 to slide inside the sliding groove 11 opened inside the fixed base 12, so that the support frame 8 can be moved and adjusted on the top of the fixed base 12. Then, the locking block 10 is sleeved on the front end of the connecting screw 20 and contacts the fixed base 12 to lock the support frame 8, thereby realizing the sliding adjustment function.

[0029] The rear end of the upper support rod 1 is fitted with a rear adjustable armrest 2, the bottom of the two sides of the rear end of the fixed base 12 is fitted with a movable side groove 21, the two sides of the movable side groove 21 are provided with limit groove seats 22, the outside of the movable side groove 21 is fitted with a sliding buckle 23, and the two sides of the rear end of the fixed base 12 are fitted with movable wheels 17.

[0030] The limiting slot seat 22 inside the movable side groove 21 slides on the sliding buckle 23 outside the fixed base 12, and the movable side groove 21 slides at the bottom of the fixed base 12 and engages with the movable wheel 17 at the rear end of the fixed base 12.

[0031] Specifically, such as Figure 2 and Figure 4 As shown, by setting an adjustment limit structure, when in use, the adjustment handle 2 is tilted to the upper support rod 1 and the lower support rod seat 6, so that the moving wheel 17 at the rear end of the fixed base 12 contacts the ground, and the moving wheel 17 drives the fixed base 12 to move. After the movement is completed, the limit slot seats 22 opened on both sides of the moving side groove 21 at the bottom of the rear end of the fixed base 12 are moved at the bottom of the fixed base 12 by the sliding buckle 23, and the moving wheel 17 at the rear end of the fixed base 12 is fitted, thereby realizing the adjustment limit function.

[0032] Working Principle: In use, the handrail 2 is first adjusted to tilt the upper support rod 1 and lower support rod seat 6, causing the movable wheel 17 at the rear end of the fixed base 12 to contact the ground. The movable wheel 17 then moves the fixed base 12. After movement, the limiting slots 22 on both sides of the movable side groove 21 at the bottom rear end of the fixed base 12 move along the bottom of the fixed base 12 via sliding buckles 23, thus securing the movable wheel 17 at the rear end of the fixed base 12. The movable wheel 17 will not move. After different widths of wires are fitted onto the limiting covers 7 of varying widths, the limiting covers 7, carrying the wires, are fitted onto the outside of the wire mounting rod 13. Then, the movable crossbar 9 is snapped into the mounting groove 15 at the top of the support frame 8. The support frame 8 then slides inside the fixed base 12 via the snap-fit ​​block 19, moving the support frame 8... The internally inserted connecting screw 20 slides within the sliding groove 11 inside the fixed base 12, adjusting the support frame 8 on top of the fixed base 12. Then, the locking block 10 is fitted onto the front end of the connecting screw 20 and contacts the fixed base 12 to lock the support frame 8. One end of the wire outside the limit cover 7 is pulled out. Then, the movable crossbar 9 is stretched inside the telescopic grooves 18 on both sides of the upper support rod 1 by the telescopic spring 14, placing the wire between the upper branching pulley 3 and the lower branching pulley 5. The movable crossbar 9 rebounds inside the telescopic groove 18 through the telescopic spring 14, causing the lower branching pulley 5 outside the movable crossbar 9 and the lower branching pulley 5 outside the upper support crossbar 4 to clamp the wire. When the wire moves inside the upper branching pulley 3 and the lower branching pulley 5, the upper branching pulley 3 and the lower branching pulley 5 will rotate outside the upper support crossbar 4 and the movable crossbar 9, respectively.

[0033] 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.
