If this problem is not solved, it will lead to low construction efficiency and it is difficult to ensure that the erected line reaches the ideal height. For example, when wind power construction is carried out in the current complex terrain, if the stringing height cannot be quickly and accurately adjusted, the project progress may be delayed and the cost may be increased. In addition, inaccurate height setting may also lead to reduced power transmission efficiency and even cause safety hazards. SUMMARY

[0028] The embodiment provides a kind of temporary stringing equipment for wind power construction as shown in Figures 1 to 5 The embodiment provides a kind of temporary stringing equipment for wind power construction as shown in

[0029] In the embodiment, rectangular through slot 7 is arranged in the lower part of installation gap groove 4 and in stringing column 2, installation gap groove 4 and rectangular through slot 7 are longitudinally through and together present inverted T-shaped gap structure.T-shaped block 10 is integrally formed with block limiting clamp 14 which is matched with T-shaped slot 8 at the end away from stringing arc-shaped rod 5, and each stringing arc-shaped rod 5 presents an arc shape structure with the arc center upward.

[0030] In the embodiment, the top end of the two T-shaped slots 8 extends through to the rectangular through slot 7, so that the block limiting clamp 14 of the T-shaped block 10 is installed and removed from the rectangular through slot 7. The top surface of each T-shaped block 10 is welded with a lifting ring 12 for hoisting connection of the pulling rope 11, and the bottom surface of each T-shaped block 10 is welded with a counterweight ball 13, so that the T-shaped block 10 can be lowered by gravity when there is no upward pulling force. The design of the counterweight ball 13 balances the pulling force of the lifting ring 12 when the T-shaped block 10 rises, preventing the block limiting clamp 14 from being stuck in the T-shaped slot 8.

[0031] In the embodiment, the lower end of the stringing column 2 has a cavity for mounting the winding crank assembly, and the winding crank assembly drives the pulling and unwinding action of the pulling rope 11 in the cavity. The two sides of the cavity and the two side outer walls of the stringing column 2 are mounted with detachable side plates 15 by screws, and the eccentric side of each detachable side plate 15 is embedded with a sealed bearing 19.

[0032] In this embodiment, two groups of winding crank assemblies are arranged on the two detachable side plates 15, so that each group of winding crank assemblies controls the driving of a corresponding one of the pull ropes 11. Each winding crank assembly comprises an L-shaped crank 16 in interference fit with the sealing bearing 19 on one of the detachable side plates 15, and a winding shaft 18 welded to the free end of the L-shaped crank 16.

[0033] In this embodiment, each winding shaft 18 is fixedly connected to a corresponding one of the pull ropes 11 in the chamber, and the end of the winding shaft 18 away from the L-shaped crank 16 is in interference fit with the sealing bearing 19 on the inner wall of the detachable side plate 15. The outer wall of each detachable side plate 15 is provided with a plurality of first limiting holes 17 arranged in a ring, and the free end of each L-shaped crank 16 is provided with a second limiting hole 20. When the position of the L-shaped crank 16 needs to be fixed and locked after the pull or winding is completed, a pin shaft or a bolt is passed through the second limiting hole 20 and one of the first limiting holes 17 to lock the position. A plurality of support ribs 3 are symmetrically welded between the top surface of the mounting base 1 and the outer wall of the stringing column 2. The inner bottom wall of the rectangular through slot 7 is symmetrically provided with two threading holes 9 for threading the two pull ropes 11, and each threading hole 9 extends downward to the chamber in the lower part of the stringing column 2 for the pull rope 11 to extend through the threading hole 9 to the chamber and be fixedly connected to the winding shaft 18.

[0034] Working principle:

[0035] The temporary stringing device for wind power construction is installed at a suitable position on the construction site, and the mounting base 1 is ensured to be stable. Then the stringing column 2 is welded on the mounting base 1 to ensure that the stringing column 2 is vertically stable. The T-shaped slider 10 is installed or adjusted through the rectangular through slot 7. One end of the T-shaped slider 10 is connected to the stringing arc-shaped rod 5, and the other end is connected to the T-shaped sliding slot 8 through the slider limiting clamp 14 to realize the function of moving up and down. At the same time, the counterweight ball 13 is welded at the bottom of the T-shaped slider 10 to provide a certain gravity for the slider to assist its downward movement.

[0036] The pull rope 11 is wound around the pulley 6 in the mounting gap groove 4, one end is connected to the lifting ring 12 on the T-shaped slider 10, and the other end is extended through the threading hole 9 to the chamber and fixed to the winding shaft 18. By rotating the L-shaped crank 16, the winding shaft 18 is driven to rotate, thereby controlling the winding and unwinding of the pull rope 11.

[0037] When the overhead line arc-shaped pole 5 needs to be lifted, the L-shaped handle 16 is rotated clockwise, the pulling rope 11 is tightened, and the T-shaped sliding block 10 and the overhead line arc-shaped pole 5 on the T-shaped sliding block 10 are moved upwards along the T-shaped sliding groove 8. When the overhead line arc-shaped pole 5 reaches the required height, the position of the L-shaped handle 16 can be locked by passing a pin shaft or a bolt through the second limiting hole 20 and one of the first limiting holes 17, so as to prevent the L-shaped handle 16 from being loosened accidentally. The line can be temporarily fixed on the overhead line arc-shaped pole 5, and the temporary line construction is completed.

[0038] When the overhead line arc-shaped pole 5 needs to be lowered or the position of the line needs to be adjusted, the locking state of the L-shaped handle 16 is released, the L-shaped handle 16 is rotated counterclockwise, and the pulling rope 11 is loosened. At this time, due to the action of the counterweight ball 13, the T-shaped sliding block 10 will slowly descend due to gravity until it reaches the predetermined position.

[0039] During use, if the internal components need to be inspected or repaired, the operation can be performed by removing the detachable side plate 15. The design of the sealing bearing 19 helps to reduce friction and prolong the service life of the equipment.
