Description

A fixing device for hanging power wires

Technical Field

The invention relates to a wire fixing device, in particular to a fixing device for hanging power wires.

Background Art

In the daily operation and maintenance of the power system, the stability of power lines is crucial to ensure the continuity and safety of power transmission. After the power lines are fixed at both ends, over time and under the influence of various external factors, such as wind in the natural environment, thermal expansion and contraction of materials caused by temperature changes, gravity caused by ice on the surface of the wires in winter, and tiny vibrations caused by the wires themselves when carrying current, the wire segments between the fixed points at both ends may gradually become loose.

Once the wires become loose, their originally stable geometric shape will be destroyed, which will affect the stability of the wires. Loose wires not only look messy and unsightly, but more importantly, they may increase friction with surrounding objects due to swinging or vibration, causing wear of the wire insulation layer and increasing the risk of short circuits and leakage. In addition, loose wires may also affect the efficiency of power transmission, because non-ideal cable conditions may increase losses during power transmission.

In this situation, if it is difficult or impractical to directly re-secure the ends of the wires (for example, due to space limitations, cost considerations or operational complexity), then a more flexible and effective solution needs to be found to tighten and stabilize the loose wires.

Based on this, the present invention proposes a fixing device for loose power wires.

As shown in Figure 4, a locking head 401 is provided at the end of the first threaded rod 4. The locking head 401 is a hexagonal structure, that is, the staff can only rotate the first threaded rod 4 through a specific tool, thereby ensuring the stability of the locking rod 6, so that the limiting mechanism can continuously and stably limit the wire.

As shown in Figures 5, 6 and 7, it also includes a worm 11, a rotating shaft 12, a worm wheel 1201, a tightening rod 1202 and a fixed plate 13. The worm 11 and the rotating shaft 12 are vertically distributed and are rotatably connected in the wing plate 2 respectively. A worm wheel 1201 meshing with the worm 11 is arranged at the rear end of the rotating shaft 12. A fixing plate 13 is fixedly connected to the wing plate 2, and the fixing plate 13 is located at the front end of the rotating shaft 12. The rotating shaft 12 rotatably passes through the fixing plate 13. A symmetrical guide groove 1203 is opened at the front end of the rotating shaft 12. The guide groove 1203 is an oblique groove. Four tightening rods 1202 are slidably connected in the guide groove 1203. A symmetrical straight groove 1301 is opened in the fixing plate 13. The ends of the tightening rod 1202 are simultaneously limited and slid in the straight groove 1301. The tightening rod 1202 is made of hard rubber material, and the tightening rod 120 2 is located between the locking rod 6 and the limiting rod 8, so the tightening rod 1202 can wind and tighten the wire. Specifically, the worm gear 1201 can be driven to rotate by rotating the worm 11, thereby driving the rotating shaft 12 to rotate. Since the tightening rod 1202 is slidably connected to the guide groove 1203 and the straight groove 1301 at the same time, when the rotating shaft 12 rotates relative to the fixing plate 13, the position of the tightening rod 1202 will move accordingly with the overlapping part of the guide groove 1203 and the straight groove 1301. The straight grooves 1301 in this embodiment are symmetrically opened, so the two tightening rods 1202 on the left side (refer to FIG. 7) will be close to each other, and the two tightening rods 1202 on the right side will also be close to each other. When the wire passes through them, it will be slightly wound and locked by the tightening rod 1202, so as to achieve the effect of further tightening the wire.

As shown in Figures 5 and 6, it also includes a second threaded rod 10, a synchronous belt 1001 and a clamping block 14. The second threaded rod 10 is rotatably connected in the wing plate 2 and transmits the worm 11 through the synchronous belt 1001. The worm wheel 1201, the worm 11 and the synchronous belt 1001 are all provided with protective shells on the outside. In a complex external environment, the protective shell can provide a physical protection function. The clamping block 14 slides in the wing plate 2 and is arranged on the outside of the second threaded rod 10 through a threaded sleeve. The locking block 3 is provided with a clamping groove. The clamping block 14 can be slidably embedded in the clamping groove to limit and fix the locking block 3. The effect is that a knob with an anti-slip groove is fixed to the upper part of the second threaded rod 10 The staff can drive the second threaded rod 10 to rotate by turning the knob, and then transmit the worm 11 through the synchronous belt 1001, and finally drive the tightening rod 1202 in the rotating shaft 12 to move, so as to wind and tighten the wire. In the initial state, the card block 14 is located in the card slot to fix the locking block 3. As the tightening rod 1202 winds and tightens the wire, the card block 14 will also be separated from the card slot and release the fixation of the locking block 3. The locking block 3 will perform adaptive position adjustment according to the tightening state of the wire, which is specifically achieved by the guide rod 9 and the second return spring 901, so that the overall stress of the wire can be balanced and the stress concentration point can be eliminated.

As shown in Figure 8, it also includes an adjusting rod 15. The upper end of the limit rod 8 is rotatably connected to the adjusting rod 15. The outer side of the adjusting rod 15 is provided with a thread. The adjusting rod 15 is connected to the mounting seat 7 through the thread. The height of the limit rod 8 can be adjusted by rotating the adjusting rod 15, so that the pushing distance of the limit rod 8 on the wire can be adjusted to make appropriate adjustments according to the actual looseness of the wire.

The working principle of the embodiment of the present invention is as follows: an external fixing column is erected between two adjacent electric poles where the wires are loose, and the fixing ring 16 in the fixer is composed of two half rings installed opposite to each other. The fixing ring 16 is sleeved on the fixing column, and then the two parts of the fixing ring 16 are fixed by fastening screws 17, so that the main board 1 and the wing plate 2 are fixed on the fixing column, and the loose wires are respectively put in through the locking blocks 3 at both ends, and the staff rotates the lock head 401 with a special tool to drive the first threaded rod 4 to rotate, and the push block connected to the first threaded rod 4 5 pushes the locking rod 6 to rotate, the locking rod 6 will clamp and limit the wire, and then the middle end of the wire is placed in the limiting rod 8, and the wire is pushed by the clamping ring at the bottom of the limiting rod 8, and the extension length of the limiting rod 8 relative to the mounting frame is adjusted by rotating the adjusting rod 15, so that the wire can be supported and made straight. Compared with the loose state, the wire has improved stability at this time, ensuring the stability of power transmission. In order to improve the stress balance of the wire, the wire can be wound between the tightening rods 1202, and then the second threaded rod 10 is rotated, and the second The threaded rod 10 drives the worm 11 to rotate through the synchronous belt 1001, and the worm 11 can drive the worm wheel 1201 to rotate, thereby driving the rotating shaft 12 to rotate. Since the tightening rod 1202 is slidably connected to the guide groove 1203 and the straight groove 1301 at the same time, when the rotating shaft 12 rotates relative to the fixed plate 13, the position of the tightening rod 1202 will move accordingly with the overlapping part of the guide groove 1203 and the straight groove 1301, so the two sets of tightening rods 1202 will approach each other, and the tightening rods 1202 will lightly tighten the wires passing through them. Micro-winding and locking can further tighten the wire. At the same time, after the wire is slightly wound, the bending degree of the wire by the limit rod 8 and the locking block 3 is reduced. At the same time, the rotation of the second threaded rod 10 will drive the card block 14 to disengage from the card slot and thereby release the fixation of the locking block 3. The locking block 3 will adaptively adjust its position according to the tightening state of the wire, which is specifically achieved through the guide rod 9 and the second return spring 901, so that the overall stress of the wire can be balanced, the stress concentration point can be eliminated, the tension on the wire can be reduced and its service life can be increased.
