[0001] This utility model relates to the technical field of isolation plate hanging and lifting equipment, and in particular to an automatic device for hanging and lifting phase spacer bars in overhead transmission lines. Background Technology

[0002] Overhead transmission lines are crucial for power transmission, and their stable operation is essential for power supply reliability. Anti-galloping phase-to-phase spacers are of great significance in suppressing conductor vibration, wear, and phase-to-phase flashover; their installation and retrieval are core tasks of line maintenance. Previously, the installation and removal of anti-galloping phase-to-phase spacers relied mainly on manual labor. Transmission lines are located in complex environments with high and widely distributed towers, requiring workers to climb towers, carry tools, and work at heights in harsh weather conditions. This involved high labor intensity, demanding high skill and psychological resilience, and was prone to accidents such as falls from heights, resulting in injuries and economic losses. Therefore, an automatic phase-to-phase spacer attachment device for overhead transmission lines was designed. Using a drone as a carrier, and equipped with a specially designed gripping and electromagnetic adsorption mechanism, the device can lift and remove anti-galloping phase-to-phase spacers, improving operational efficiency and safety. Utility Model Content

[0003] The purpose of this utility model is to provide an automatic phase-to-phase spacer device for overhead transmission lines, which can use a drone as a carrier and a specially designed gripping and electromagnetic adsorption mechanism to lift and dismantle anti-galloping phase-to-phase spacers, thereby improving the efficiency and safety of the operation.

[0004] The technical implementation scheme of this utility model is as follows:

[0005] An automatic phase-to-phase spacer attachment device for overhead transmission lines includes a first connecting support, a second connecting support, a connecting column, and an automatic clamping mechanism.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0024] like Figures 1-6 As shown, an automatic phase-to-phase spacer mounting device for an overhead transmission line includes a first connecting support 1, a second connecting support, a connecting column 7, and an automatic clamping mechanism 6. The first connecting support 1 forms a support structure with the second connecting support via a fiberglass connecting column 5. The bottom of both the first and second connecting supports is equipped with the automatic clamping mechanism 6. The automatic clamping mechanism 6 includes a drive motor 601, a drive box 602, a screw 603, a sliding groove 605, a fixed groove 607, and a slide bar 606. The drive motor 601 is located at the bottom of the first connecting support 1, and its output shaft is connected to the drive box 602. The drive box 602 contains a screw 603, one end of which is connected to the sliding groove 605. The upper part of the slot 605 is slidably connected to the slide bar 606 on the fixed support 604 via a sliding groove; the upper part of the fixed support 604 is connected to the bottom of the first connecting support 1 via a connecting column 7, and the fixed support 604 is provided with an electromagnet and an electromagnetic guide seat 11, and an anti-galling spacer 10 is installed inside the electromagnetic guide seat 11; the upper part of the fixed support 604 is provided with a through hole, and a rotating cylinder 611 is provided inside the through hole, and the rotating cylinder 611 is connected to the screw 603 via an internal thread 612; a bearing is provided at the connection between the rotating cylinder 611 and the through hole; the drive box 602 is provided with a worm gear 610 and a worm 609, the worm 609 is provided on the output shaft of the drive motor 601, and the worm 609 is meshed with the worm gear 610 on the rotating cylinder 611.

[0025] It should be noted that the first connecting support 1 forms a support structure with the second connecting support through the fiberglass connecting rod 5, and the fiberglass connecting rod 5 is connected to the hoisting equipment of the drone. The drone can hoist the entire equipment to a high altitude, and the anti-galloping phase spacer 10 is hoisted through the electromagnetic clamping mechanism at the bottom. The bottom of the first connecting support 1 and the second connecting support is connected to the fixed support 604 through the connecting column 7, and the fixed support 604 is provided with an electromagnetic guide seat 11, which contains the anti-galloping phase spacer 10. During transportation, it can be clamped by an electromagnet. After reaching the corresponding position, the electromagnet is turned off, and the anti-galloping phase spacer 10 is sent into the cable installation position under the guidance of the electromagnetic guide seat 11, so as to cooperate with the operators to complete the hoisting and feeding.

[0026] It should be further explained that in the drone delivery scenario, after the drone arrives at the designated location, considering the strong winds during high-altitude operations, to ensure the stability of the entire equipment during the guidance process of the anti-galling spacer bar 10, we have specially designed an automatic clamping mechanism 6. The working principle of this automatic clamping mechanism 6 is as follows: the drive motor 601 provides power to drive the worm gear 609 to rotate. The worm gear 609 meshes with the turbine 610 on the rotating drum 611. When the worm gear 609 rotates, it drives the rotating drum 611 to rotate synchronously through this meshing relationship. The rotating drum 611 has an internal thread. The internal thread matches the screw 603. Therefore, when the drum 611 rotates, the screw 603 will move left and right according to the thread transmission principle. The left and right movement of the screw 603 will directly drive the sliding groove 605 to make corresponding displacements. During this process, the sliding groove 605 will move closer to or away from the fixed groove 607 fixed at the other end. When it is necessary to lock the cable, the drive motor 601 starts, driving the sliding groove 605 to move towards the fixed groove 607 until the two together tightly clamp the cable, thereby completing the reliable locking of the cable and effectively enhancing the stability of the equipment in high-altitude and strong wind environments.

[0027] like Figures 1-6 As shown, a fixed slot 607 is provided at one end of the fixed support 604, and the fixed slot 607 is correspondingly provided with the sliding slot 605; a connecting rod is provided on the upper part of the first connecting support 1, and a guide bracket 8 is provided on the connecting rod; a support frame 4 is provided on the upper part of the fiberglass connecting rod 5; a fixed ear 2 is provided on the upper part of the first connecting support 1, and the fiberglass connecting rod 5 is located inside the fixed ear 2; a battery and a control box are provided inside the first connecting support 1.

[0028] It should be noted that the guide bracket 8 is set for positioning. During the transport of the UAV, the guide bracket 8 is used to position the cable. The automatic clamping mechanism (6) can then fix and limit the cable. The first connecting support 1 and the second connecting support are equipped with a battery and a control box. During operation, they can be used to start and disconnect the electromagnet, and can also control the opening and closing of the drive motor, thereby realizing automatic clamping operation.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
