Description

Technical Field

[0001] This utility model relates to the field of guyed pole construction technology, and in particular to fastening and adjusting hardware for guyed poles. Background Technology

[0002] Guy wire fittings, using components such as wedge clamps and UT clamps, securely connect the tower to the guy wire, ensuring the tower remains stable under external forces such as wind and gravity. By adjusting the tension of the guy wire, the fittings balance the forces on the tower in all directions, preventing the tower from tilting or collapsing and ensuring the safe operation of the transmission line. In guy wire towers, the fittings also undertake the task of suspending and fixing conductors and lightning protection wires, ensuring that the mechanical strength of electrical equipment meets safety standards.

[0003] When connecting, insert the wire into the fitting and tighten the nut. The tightening force of the nut should be moderate. Too tight will cause damage, and too loose will result in a loose connection. Existing fittings often require tightening multiple nuts to secure the fitting. Installing the fitting takes a lot of time. Furthermore, because the space between the fitting and the nut is small, it is extremely inconvenient to operate with tools such as wrenches. The wrench needs to be turned repeatedly to tighten it, which also takes time. All of these factors combined result in an inability to flexibly adjust the tension of the pull cable. Utility Model Content

When the tightness of the guy wire needs to be adjusted, no additional tools are required, which is convenient and quick. The tightness of the guy wire can be flexibly adjusted as needed. The drive assembly provides a support point, making the adjustment more labor-saving and convenient.

[0017] Please see Figure 2 and Figure 3 In this embodiment, a flange bearing 6 is fixedly installed on the surface of the movable disk 5. The flange bearings 6 are distributed in a ring around the edge of the movable disk 5. A threaded seat 7 is fixedly installed at the center of the surface of the movable disk 5. The threaded seat 7 is threadedly connected to the threaded rod 4. Multiple guide shafts 8 are fixedly installed on one side of the outer casing 1. The guide shafts 8 are slidably connected to the flange bearings 6. A cavity is provided inside the support column 9. The threaded rod 4 is located in the cavity of the support column 9. A movable plate 11 is slidably connected to the surface of the hanger 10. A locking nut 12 is threadedly connected to one side of the hanger 10. The locking nut 12 is used to fasten the movable plate 11. A bearing seat 13 is fixedly installed on the surface of the outer shell 1 of plate 11. A worm gear 14 is rotatably connected between the two bearing seats 13. The worm gear 14 is meshed with the worm wheel 3. When it is necessary to adjust the tightness of the pull cable, hold and rotate the rotating handle 15. The worm gear 14 rotates at the bearing seat 13, and the worm wheel 3 meshing with the worm gear 14 rotates at the same time. The threaded rod 4 rotates at the same time, and the moving disc 5 slides on the surface of the guide shaft 8 at the same time. The bracket 10 at one end of the support column 9 moves towards the middle at the same time, thus tightening the pull cable. When it is necessary to loosen the pull cable, rotate the rotating handle 15 in the opposite direction.

[0018] Please see Figure 1 and Figure 5 In this embodiment, the drive assembly includes a rotating handle 15, which is fixedly connected to one end of the worm gear 14. A telescopic support frame 16 is rotatably connected to the rotating shaft surface of the rotating handle 15. A fastening handle 17 is threadedly connected to the surface of the telescopic support frame 16, which is used to fix the telescopic end of the telescopic support frame 16. A base plate 21 is fixedly connected to the telescopic end of the telescopic support frame 16.

The moving disc 5 slides on the surface of the guide shaft 8. The flange bearing 6 is used to ensure the stability of the moving disc 5. The support column 9, which is fixedly connected to the surface of the moving disc 5, moves simultaneously. The bracket 10 at one end of the support column 9 moves towards the center, thus tightening the pull cable. To loosen the pull cable, simply rotate the handle 15 in the opposite direction.

[0021] When rotating the handle 15, the telescopic end of the telescopic support frame 16 is extended and the base plate 21 contacts the ground. Then, the fastening handle 17 is locked, and the telescopic end of the telescopic support frame 16 is fixed. Then, the foot is pressed down on the pedal 18, so that the positioning pin 19 is inserted into the ground to complete the positioning. This provides a support point for rotating the handle 15, making it easier to rotate the handle 15. After the adjustment is completed, the pedal 18 is released, and the spring 20 pulls the positioning pin 19 out of the ground.

[0022] Through the above steps, when the tightness of the guy wire needs to be adjusted using the fastening and adjusting hardware of the guy wire tower, no additional tools are required, which is convenient and quick. The tightness of the guy wire can be flexibly adjusted as needed. When rotating the handle 15, the telescopic end of the telescopic support frame 16 is extended and fixed. Then, the foot is pressed down on the pedal 18, so that the positioning pin 19 is inserted into the ground to complete the positioning. This provides a support point for rotating the handle 15, making it easier and less strenuous to rotate the handle 15.
