Description

Technical Field

[0001] This utility model relates to the field of high-voltage transmission line maintenance technology, and in particular to a double-split conductor maintenance device. Background Technology

[0002] The manned maintenance device for double-split conductors plays a crucial role in high-voltage line maintenance. It allows maintenance personnel to directly access fault points on high-voltage lines without the need for complex scaffolding or other high-altitude work equipment, significantly saving time and labor costs. It enables rapid fault diagnosis and repair, shortening power outage time and improving power supply reliability. As long as safety regulations and operating procedures are strictly followed, it provides a relatively safe working environment for maintenance personnel. However, existing simple manned maintenance devices for double-split conductors are inconvenient for storage and cannot help workers carry maintenance tools, requiring workers to carry multiple tools directly, resulting in additional physical exertion and increased fatigue.

[0023] The present invention will be further described in detail below with reference to the embodiments.

[0024] Specific embodiments of the double-split conductor maintenance device provided by this utility model:

[0025] Please see Figure 1-4 The double-split conductor maintenance device includes a rectangular frame 1, pulleys 2, work chair 3, and toolbox 5.

[0026] The rectangular frame 1 forms a ring-shaped enclosure structure that can protect maintenance personnel. Pulleys 2 are installed on the upper side of the rectangular frame 1 and roll along the conductor. There are four pulleys 2. During the maintenance of double-split conductors, every two pulleys 2 are aligned one after the other and roll along the upper side of the same conductor.

[0027] Two inverted U-shaped screws 8 are threaded through both ends of the rectangular frame 1. The threaded section of the lower end of the inverted U-shaped screw 8 passes through the rectangular frame 1, and the rectangular frame 1 has through holes for the inverted U-shaped screws 8 to pass through. Four fastening nuts 9 are threadedly connected to the outer side of the lower end of the inverted U-shaped screw 8. The lower end of the inverted U-shaped screw 8 has two threaded sections, and at least two fastening nuts 9 are located on the outer side of each threaded section. The two fastening nuts 9 are located on the upper and lower sides of the rectangular frame 1, respectively. In this embodiment, the pulley 2 is rotatably installed on the inner side of the upper end of the inverted U-shaped screw 8, and the wire passes through the inner side of the upper end of the inverted U-shaped screw 8.

[0028] The rectangular frame 1 is equipped with cup holders 7 at both the front and rear ends; the cup holder 7 is a cylindrical structure with a closed bottom and an opening at the top, which is located on the upper side of the rectangular frame 1. The cup holder 7 can hold water bottles, making it convenient for maintenance personnel to drink water.

[0029] The work chair 3 is connected to the lower side of the rectangular frame 1, and several reinforcing rods 4 connect the work chair 3 and the rectangular frame 1. In this embodiment, the work chair 3 includes a seat and a backrest. The seat corresponds to the lower side of the rectangular frame 1. When the maintenance personnel sit on the work chair 3, their upper body passes through the inside of the rectangular frame 1, and the rectangular frame 1 provides protection for the personnel. The upper end of the backrest is connected to the rectangular frame 1, and reinforcing rods 4 are connected to both ends of the seat and the rectangular frame 1. Armrests 10 are provided on both sides of the seat of the work chair 3 to improve the comprehensiveness of protection and provide support for maintenance personnel.

[0030] The toolbox 5 is located below the front side of the work chair 3, and several inclined connecting rods 6 connect the toolbox 5 and the lower side of the work chair 3. The toolbox 5 has an opening on the upper side for easy access to maintenance tools by maintenance personnel. An inclined foot pedal 14 is connected to the upper front side of the toolbox 5, and the upper edge of the foot pedal 14 is inclined away from the work chair 3. When maintenance personnel are sitting on the work chair 3, they can place their feet on the foot pedal 14 to improve comfort.

[0031] Link 6 connects to a standing support plate 11, which is parallel to the seat of the work chair 3 and located directly below the seat. The seat of the work chair 3 has a notch, and a movable plate 12 is located at the notch. The movable plate 12 has a first state of covering the notch and a second state of not covering the notch. When the movable plate 12 covers the notch, maintenance personnel can sit on the work chair 3 and the movable plate 12. When the movable plate 12 does not cover the notch, maintenance personnel can stand on the upper side of the standing support plate 11, with their legs passing through the notch in the seat of the work chair 3. Compared to standing directly on the upper side of the seat of the work chair 3, this reduces the standing height, improves safety, and facilitates maintenance work.

[0032] In this embodiment, the movable plate 12 is rotatably connected to the inner end of the notch; a support strip 13 supporting the movable plate 12 is provided on the lower side of the work chair 3 at the edge of the notch; when the movable plate 12 is rotated to a horizontal position, as... Figure 1 In the first state, the movable panel 12 is in the position of covering the notch, and the work chair 3 can be used for seating; when the movable panel 12 is rotated to rest against the backrest, as... Figure 4 In the first state, the movable plate 12 is in the second state where the notch is partially blocked, and the standing support plate 11 can be used for standing. In some other embodiments, the movable plate 12 can be translated or detached to achieve the transition between the first and second states, instead of rotating the movable plate 12 in this embodiment.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
