Description

TECHNICAL FIELD

[0001] The utility model relates to the technical equipment field of clamp, specifically is a positioning and clamping device for line column type insulator processing. BACKGROUND

[0002] In modern power systems, insulators play an irreplaceable role as key components to ensure the safe and stable operation of power transmission. Insulators are mainly used to support and fix conductors, while ensuring good electrical insulation between conductors and objects of different potentials such as towers and ground. Line column type insulators are widely used in various overhead transmission lines and substations due to their unique structure and performance, and are subjected to high voltage, mechanical stress and complex natural environmental factors.

[0003] In order to improve the performance of insulators in harsh environments, insulator anti-fouling coating spraying processing has become a common and effective protection method. Anti-fouling coating can form a protective film with hydrophobicity on the surface of the insulator, effectively reducing the adhesion of contaminants on the surface of the insulator, reducing the risk of flashover caused by contamination, and improving the reliability and stability of power system operation. However, in the process of insulator anti-fouling coating spraying, accurate positioning and stable clamping of the insulator are crucial.

[0004] In existing insulator processing operations, the clamps used have many problems. Among them, the positioning of the clamp is not accurate enough, which is a prominent problem. Due to positioning deviation, the insulator may not be accurately positioned at the ideal spraying position during spraying, resulting in uneven anti-fouling coating spraying and affecting the anti-fouling performance of the insulator. For example, in some traditional clamp designs, the positioning method is relatively simple and rough, relying only on manual experience or basic mechanical limiting structure, which is difficult to meet the requirements of modern high-precision processing. When facing insulators of different specifications and shapes, it is difficult to flexibly and accurately adjust the positioning, making it difficult to ensure the processing quality.

[0005] In addition, the clamping force of the clamp is also a big problem. On the one hand, if the clamping force is too large, the relatively fragile insulator is easily clamped. The insulator is usually made of ceramic, glass and other materials, which have good insulation performance, but are easy to break and damage under excessive external force. Once the insulator is clamped in the processing, not only the material is wasted, the production cost is increased, but also the production progress is delayed. On the other hand, if the clamping force is too small, it is also difficult to achieve stable clamping. During the movement, the insulator is easy to shake or even fall off, which leads to the interruption of processing, and may also cause damage to the processing equipment, and the fallen insulator may also bring safety hazards. For example, in some simple clamps, only the spring or simple screw fastening method is used to adjust the clamping force, which cannot accurately adjust the clamping force according to the actual situation of the insulator, and it is difficult to achieve stable clamping without damaging the insulator.

[0006] In summary, it is of great practical significance to develop a positioning and clamping device that can accurately position, stably clamp and avoid damaging the insulator, in order to improve the quality and efficiency of insulator anti-fouling coating spraying processing.

[0057] Working principle: First, the feeding mechanism moves the insulator to be processed to the vicinity of the device, at which time the chuck 3 is at the feeding point. Then, the chuck 3 starts the clamping action and firmly holds the insulator. Next, the horizontal moving device 2 starts to work, driving the chuck 3 and the clamped insulator to move in the horizontal direction and accurately reach the processing point. At this point, the insulator receives the anti-fouling coating processing and other related operations. After the processing is completed, the horizontal moving device 2 operates again, driving the chuck 3 to move to the discharging point, releasing the chuck and completing the discharging operation. After discharging is completed, the moving device 2 drives the chuck 3 to move reversely, quickly returning to the feeding point, preparing to welcome the next insulator to be processed, and so on, realizing efficient and continuous processing operation. The core operation of the horizontal moving device 2 is based on the cooperation of the threaded screw 4 and the first servo motor 8. The threaded screw 4 installed on one side of the mounting plate surface 1 is stably welded with the mounting plate surface 1 to ensure the stability of the structure. On the side of the threaded screw 4 away from the mounting plate surface 1, the movement track 5 welded with it provides a precise sliding path for the slider 6. The first servo motor 8 is fixed on one side of the threaded screw 4, and its output end is coaxially connected with the screw rod of the threaded screw 4. When the chuck 3 needs to move horizontally, the first servo motor 8 is controlled to rotate. The rotation of the motor drives the screw rod of the threaded screw 4 to rotate. Since the slider 6 is welded with the movement part of the threaded screw 4 and is slidingly connected in the movement track 5, the rotation of the screw rod drives the slider 6 to move forward and backward along the movement track 5 in the single-axis direction. Because the servo motor only rotates one circle, the chuck only produces a very small displacement in the horizontal direction, so it can realize accurate positioning movement of the chuck 3 in the horizontal direction, providing reliable position guarantee for subsequent processing operations. The clamping action of the chuck 3 is completed by the synchronous contraction structure and the driving structure. In the driving structure, after the second servo motor 22 in the driving cavity 11 is started, its output end drives the second gear 21 coaxially connected with it to rotate. Since the second gear 21 is meshed with the first gear 20, the rotating shaft 19 is coaxially connected with the rotating disc 14, the first gear 20 is coaxially connected with the rotating shaft 19, and the second gear 21 is meshed with the first gear 20, the rotation of the second gear 21 drives the first gear 20 to rotate, thereby driving the rotating shaft 19 to rotate, and finally making the rotating disc 14 start to rotate. The rotation of the rotating disc 14 triggers the synchronous contraction structure to work. The three groups of trajectory grooves 16 distributed circumferentially on the rotating disc 14 rotate with the rotating disc 14, and the distance from the transmission rod 18 in the trajectory groove 16 to the center will increase or decrease during the rotation. Because the transmission rod 18 is welded with the sliding link 17, and the sliding link 17 is slidingly connected in the slide groove 15 circumferentially opened on the base block 10, the position change of the transmission rod 18 drives the sliding link 17 to expand outward or contract inward in the slide groove 15. The end of the sliding link 17 away from the rotating disc 14 is welded with the three groups of arc-shaped clamping blocks 13, which makes the three groups of arc-shaped clamping blocks 13 move synchronously.When the insulator needs to be clamped, the three sets of arc-shaped clamping blocks 13 are synchronously contracted inward, uniformly applying pressure on the insulator from all angles, achieving stable clamping; when the insulator needs to be released, the clamping blocks 13 are synchronously expanded outward. Moreover, the transmission cooperation of the first gear 20 and the second gear 21 effectively reduces the rotating speed, further improves the clamping precision, and ensures that the insulator will not be damaged in the clamping process.
