Description

Technical Field

[0001] This utility model relates to the field of adjustment device technology, specifically to a segmented insulator adjustment device. Background Technology

[0002] Sectional insulators are insulating devices used when electrical sections of the overhead contact system are segmented. Under normal circumstances, the pantograph slides under energized conditions. When a section of the contact system malfunctions or is shut down due to construction, the isolating switch at the sectional insulator is opened to disconnect that section of the contact system, while other sections can be powered normally. When the two parts of the contact system are powered separately, if the power supply to one part of the contact system fails, the isolating switch can be closed to allow it to use a single power supply, thereby improving the reliability and flexibility of the contact system operation.

[0003] During the installation of segmented insulators, it is necessary to keep both ends of the segmented insulator horizontal. If the two ends are not horizontal and there is a height difference, it may cause the contact wire to jump or arc when the pantograph passes. As for the existing segmented insulator products on the market, there is a common problem: the lack of a device that can effectively adjust and correct whether the two ends are horizontal. This deficiency means that when installing segmented insulators, installers can only make rough adjustments based on experience and some traditional measuring tools, which makes it difficult to ensure the horizontality of the two ends of the segmented insulator. Therefore, this application proposes a segmented insulator adjustment device. Utility Model Content

[0004] To solve the above-mentioned technical problems, this application provides a segmented insulator adjustment device, including a segmented insulator body and an adjustment component. The adjustment component includes a first positioning frame, a first correction plate, a first gravity support block, a second positioning frame, a second correction plate, a second gravity support block, and a laser pointer.

[0005] The No. 1 positioning frame and the No. 2 positioning frame are respectively fixedly connected to both sides of the segmented insulator body. The No. 1 gravity support block is fixedly connected to the lower end of the No. 1 correction plate. The No. 2 gravity support block is fixedly connected to the lower end of the No. 2 correction plate. The No. 1 correction plate is rotatably connected inside the No. 1 positioning frame. The No. 2 correction plate is rotatably connected inside the No. 2 positioning frame. The laser pointer is fixedly connected to the No. 2 correction plate.

[0006] In some embodiments, the adjustment assembly further includes a first positioning head and a second positioning head, which are fixedly connected to both sides of the segmented insulator body, and through holes are provided on the first positioning frame and the second positioning frame corresponding to the positions of the first positioning head and the second positioning head.

[0007] In some embodiments, the adjustment assembly further includes fastening bolts, and screw holes are provided on both sides of the segmented insulator body. The first positioning frame and the second positioning frame are respectively fixedly connected to the segmented insulator body by fastening bolts. The first positioning head is inserted into the first positioning frame, and the second positioning head is inserted into the second positioning frame.

[0008] In some embodiments, the adjustment assembly further includes a first bearing and a first rotating rod, the first rotating rod being fixedly connected in a first positioning frame, and the first positioning frame being rotatably mounted to the first rotating rod via the first bearing.

[0009] In some embodiments, the adjustment assembly further includes a second bearing and a second rotating rod, the second rotating rod being fixedly connected inside a second positioning frame, and the second positioning frame being rotatably connected to the second rotating rod via the second bearing.

[0010] In some embodiments, the adjustment assembly further includes a calibration ring disposed on a first calibration plate.

[0011] In some embodiments, the adjustment assembly further includes a mounting ring and positioning bolts. The mounting ring is fixedly connected to the second calibration plate, the laser pointer is movably mounted inside the mounting ring, and the positioning bolts are threadedly connected to both ends of the mounting ring. The laser pointer is fixedly connected inside the mounting ring by the positioning bolts.

[0012] This utility model has at least the following beneficial effects:

[0013] By adjusting the components, the system is calibrated on a horizontal standard plane. Under the influence of gravity, the first and second calibration plates remain vertical, and the laser pointer spot is centered on the calibration circle. After calibration, the segmented insulator body is installed. If the laser pointer spot is still centered on the calibration circle after installation, it proves that both ends of the segmented insulator body are horizontal. This structure makes it easy to adjust and calibrate the horizontal state of both ends of the segmented insulator body, improving the convenience of installation.

[0014] After installation, the fastening bolts can be unscrewed by the adjustable components, allowing the No. 1 and No. 2 positioning frames to be removed separately. This facilitates continued use on other similar segmented insulator bodies, improving the versatility of the adjustable components and reducing costs. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Please see Figures 1 to 4 This utility model provides a technical solution: a segmented insulator adjustment device, including a segmented insulator body 1, and an adjustment component 2. The adjustment component 2 includes a first positioning frame 203, a first correction plate 204, a first gravity support block 207, a second positioning frame 210, a second correction plate 211, a second gravity support block 214, and a laser pointer 216. The first positioning frame 203 and the second positioning frame 210 are respectively fixedly connected to both sides of the segmented insulator body 1.

[0025] Furthermore, the adjustment component 2 also includes a first positioning head 201 and a second positioning head 202. The first positioning head 201 and the second positioning head 202 are fixedly connected to both sides of the segmented insulator body 1, and through holes are provided on the first positioning frame 203 and the second positioning frame 210 corresponding to the positions of the first positioning head 201 and the second positioning head 202.

[0026] On both sides of the segmented insulator body 1, the No. 1 positioning head 201 and the No. 2 positioning head 202 respectively limit the position of the No. 1 positioning frame 203 and the No. 2 positioning frame 210.

[0027] Furthermore, the adjustment component 2 also includes fastening bolts 209. Screw holes are provided on both sides of the segmented insulator body 1. The first positioning frame 203 and the second positioning frame 210 are respectively fixedly connected to the segmented insulator body 1 by fastening bolts 209. The first positioning head 201 is inserted into the first positioning frame 203, and the second positioning head 202 is inserted into the second positioning frame 210.

[0028] The fastening bolts 209 pass through the first positioning frame 203 and the second positioning frame 210 respectively and are threaded to the segmented insulator body 1, thereby installing the first positioning frame 203 and the second positioning frame 210. When disassembly is required, the fastening bolts 209 can be unscrewed in sequence.

[0029] After the No. 1 positioning frame 203 and the No. 2 positioning frame 210 are inserted into the No. 1 positioning head 201 and the No. 2 positioning head 202 respectively, the fastening bolts 209 are then passed through the No. 1 positioning frame 203 and the No. 2 positioning frame 210 in sequence and installed into the screw holes on the segmented insulator body 1. After the segmented insulator body 1 is corrected and adjusted, the fastening bolts 209 are unscrewed in sequence and the No. 1 positioning frame 203 and the No. 2 positioning frame 210 can be removed. This adjustment component 2 can be reused, which reduces costs.

[0030] Example 2:

[0031] Please see Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 Based on Embodiment 1, this utility model provides another technical solution: a first gravity support block 207 is fixedly connected to the lower end of a first correction plate 204, a second gravity support block 214 is fixedly connected to the lower end of a second correction plate 211, a first correction plate 204 is rotatably connected to a first positioning frame 203, a second correction plate 211 is rotatably connected to a second positioning frame 210, and a laser pointer 216 is fixedly connected to a second correction plate 211.

[0032] Furthermore, the adjustment assembly 2 also includes a first bearing 205 and a first rotating rod 206. The first rotating rod 206 is fixedly connected inside the first positioning frame 203. The first positioning frame 203 is rotatably installed with the first rotating rod 206 via the first bearing 205. The adjustment assembly 2 also includes a second bearing 212 and a second rotating rod 213. The second rotating rod 213 is fixedly connected inside the second positioning frame 210. The second positioning frame 210 is rotatably connected with the second rotating rod 213 via the second bearing 212.

[0033] The No. 1 bearing 205 and the No. 1 rotating rod 206 facilitate the rotation of the No. 1 correction plate 204, and the No. 2 correction plate 211 facilitates its rotation by the No. 2 bearing 212 and the No. 2 rotating rod 213, thus enabling it to maintain a vertical state under the attraction of gravity.

[0034] Furthermore, the adjustment component 2 also includes a calibration ring 208, which is formed on the first calibration plate 204. The adjustment component 2 also includes a mounting ring 215 and a positioning bolt 217. The mounting ring 215 is fixedly connected to the second calibration plate 211. The laser pointer 216 is movably mounted in the mounting ring 215. The positioning bolt 217 is threadedly connected to both ends of the mounting ring 215. The laser pointer 216 is fixedly connected in the mounting ring 215 by the positioning bolt 217.

[0035] The installation ring 215 and positioning bolt 217 make it easy to disassemble structures such as the laser pointer 216, thus improving the versatility of the device.

[0036] Positioning frame 203 and positioning frame 210 are fixedly connected to both ends of the segment insulator body 1. By placing them on a horizontal standard surface, the first correction plate 204 and the second correction plate 211 are attracted by gravity and rotate downwards to maintain verticality. At this time, the light spot emitted by the laser pointer 216 is centered on the correction ring 208. Then, the segment insulator body 1 is installed with the cable. After installation, if both ends of the segment insulator body 1 are still horizontal, the laser light spot is still centered on the correction ring 208. If the two ends are not horizontal, the laser light spot will shift, which makes it easier for the staff to judge whether the two ends are horizontal and improves the convenience of installation.
