Description

Technical Field

[0001] This utility model relates to the field of power construction and maintenance technology, and in particular to a general-purpose double-split conductor lifting device. Background Technology

[0002] With the continuous expansion of the power industry, power transmission lines are widely distributed and becoming increasingly complex, and double-split conductors occupy an important position and are increasingly widely used.

[0003] When performing inspections and maintenance on double-split conductors, lifting the conductor to the appropriate position is a crucial step. However, existing horizontal and vertical double-split conductor lifters are specialized tools, and using different lifters for different types of conductors increases economic costs. Therefore, we propose a universal double-split conductor lifting device. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies, and through reasonable optimization, save costs. It can adapt to both horizontal and vertical double-split circuits, and reduce tool size, weight, and cost, thereby greatly improving maintenance efficiency and economic benefits.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A general-purpose double-split conductor lifting device includes a lifting ring, a pulley rotatably connected to the inner open end of the lifting ring, a steel wire rope passing between the lifting ring and the pulley, and conductor hooks provided at both ends of the steel wire rope;

[0007] Furthermore, the pulley is fixed inside the lifting ring via a rotating shaft.

[0008] Furthermore, the number of steel wire ropes is one, and it is inserted into the pulley groove.

[0009] Furthermore, the wire hooks are symmetrically arranged at the loops at both ends of the wire rope.

[0010] Furthermore, the pulley is made of 45# steel, and the lifting ring and the guide hook are both made of 40Cr steel.

[0011] Furthermore, the guide hook can swing horizontally and be lifted vertically.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention is applicable to both horizontal and vertical double-split lines, eliminating the need for different lifting devices to complete construction work, thus reducing workload and increasing efficiency. Its rationally designed structure results in small size, light weight, novel structure, balanced overall force distribution, strong versatility, and high safety and reliability, significantly reducing safety risks for workers, improving work efficiency, avoiding waste from purchasing different lifting devices, and saving operating costs.

[0028] Example 1

[0029] like Figure 1-9 As shown, this utility model provides a technical solution: a universal double-split conductor lifting device, including a lifting ring 1, a pulley 2 rotatably connected to the inner open end of the lifting ring 1, a steel wire rope 3 passing between the lifting ring 1 and the pulley 2, and conductor hooks 4 provided at both ends of the steel wire rope 3. The pulley 2 is made of 45# steel, and the lifting ring 1 and conductor hooks 4 are both made of 40Cr. Through a reasonable structure, it has the characteristics of small size, light weight, large load, novel structure, balanced overall force, strong versatility, and safety and reliability.

[0030] Example 2

[0031] like Figure 1-9 As shown, pulley 2 is fixed inside lifting ring 1 via rotating shaft 21.

[0032] There is one steel wire rope 3, which is inserted into the groove of pulley 2.

[0033] The wire hooks 4 are symmetrically arranged at the loops 31 at both ends of the wire rope 3.

[0034] The guide hook 4 can swing horizontally and lift vertically.

[0035] It should be noted that the size of the horizontal opening of the wire hook 4 can be adjusted by lengthening the steel wire rope 3;

[0037] The working process of this utility model is as follows: When using a universal double-split conductor lifting device:

[0038] The horizontal double-split conductor is raised by adjusting the opening size of the two conductor hooks 4 so that the hook groove of the conductor hook 4 hooks the conductor. Then, the top lifting ring 1 is connected to the lead screw, and the lead screw drives the whole body to lift the conductor.

[0039] The vertical double-split conductor is lifted by adjusting the opening size of the two conductor hooks 4 so that the hook groove of the conductor hook 4 hooks the conductor. Then, the top lifting ring 1 is connected to the lead screw, and the lead screw drives the whole to lift the conductor.

[0040] In summary, this invention can be applied to both vertical double-split circuits and horizontal double-split circuits.
