Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a segmented insulator. Background Art

[0002] A segment isolator is an insulating device used to electrically segment the catenary network. It is primarily used to electrically isolate two power supply sections in electrified railways or urban rail transit. Its primary function is to disconnect power to a specific catenary section by opening the isolating switch at the segment isolator when a fault or power outage occurs in that section, while maintaining normal power supply to the remaining sections.

[0003] By comparing a segmented insulator with patent announcement number CN219947947U, in this scheme, this device is easy to operate when installing, and it is convenient for people to install the device. When using the device, it can avoid the danger of sudden falling off caused by the loosening of a single insulator and nut. However, after the equipment has been used for a long time, the long-term friction between the train and the main slide when running may cause fluctuations in the position of the main slide, and the position of the main slide needs to be re-positioned and adjusted. Furthermore, during maintenance, it is necessary to manually level the position of the main slide through the combination of a measuring ruler and a spirit level. This operation is relatively cumbersome, not conducive to rapid maintenance, and has certain limitations. Utility Model Content

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figure 1-Figure 7 As shown, a segmented insulator includes two mounting seats 100 and a mounting mechanism for mounting and fixing the equipment. The mounting mechanism is located on the side wall of the mounting seat 100. Two main insulators 200 are symmetrical in upper and lower directions between the two mounting seats 100. It also includes a maintenance mechanism for auxiliary maintenance of the equipment. The maintenance mechanism is located below the mounting seat 100.

[0028] In this embodiment: the maintenance mechanism includes a storage frame 401 arranged at the bottom end of the mounting seat 100, and a lower pressure plate 402 is slidably installed on the upper end of the storage frame 401, and a tension spring 403 is connected between the lower pressure plate 402 and the storage frame 401, and a connecting plate 405 is fixed to the lower end of the lower pressure plate 402, and the connecting plate 405 is an inverted T-shape, and the connecting plate 405 and the lower pressure plate 402 form an H-shape with each other, and two front-to-back symmetrical support blocks 406 are slidably installed on the bottom end of the connecting plate 405, and a compression spring 407 is connected between the support block 406 and the connecting plate 405, and the support block 406 is arc-shaped at one end away from the compression spring 407, and a limiting protrusion 404 is provided on the inner wall of the storage frame 401, and a storage component for storing the support block 406 is provided under the support block 406.

[0029] The storage assembly includes a pull rope 409 arranged between the two support blocks 406, and a guide wheel 408 is rotatably installed at one end of the connecting plate 405 close to the support block 406. The pull rope 409 passes over the top of the guide wheel 408 and naturally moves vertically downward. Two symmetrical pull hooks 411 are fixed to the bottom end of the connecting plate 405, and a hook 410 is provided between the two pull hooks 411. When the equipment is repaired, the connecting plate 405 is pulled downward. When the storage frame 401 is released from the limit of the support block 406, the two support blocks 406 move toward the bottom ends of the two main slides 302 respectively, and the support block 406 squeezes the bottom end of the main slide 302 upward to adjust the bottom end of the main slide 302 to a horizontal state, and then fixes the main slide 302, and then uses the storage assembly to store the maintenance mechanism, which speeds up the maintenance time of the equipment, is simple to operate, easy to store, and improves the practicality of the device.

[0030] In this embodiment: the installation mechanism includes an auxiliary slide 301 arranged on the side wall of the main insulator 200, and a main slide 302 is provided on the front and rear sides of the mounting seat 100. A bracket 303 is provided between the main slide 302 and the mounting seat 100. The bracket 303 is connected to the mounting seat 100 by bolts. A slide 304 is slidably installed on one end of the bracket 303 near the main slide 302. The slide 304 and the bracket 303 are connected to the main slide 302 by bolts. An oblique groove is provided on the surface of the slide 304, and a vertical groove is provided on the bracket 303 near the slide 304.

[0031] The two mounting seats 100 are each provided with two front-to-rear symmetrical fixing splints 308 at one end away from each other, an upper fixing rod 305 is provided between the two fixing splints 308 above, and a lower fixing rod 307 is provided between the two fixing rods 305 and the lower fixing rod 307 at one end away from each other, and a wire hook clamp 306 is provided at the end where the two upper fixing rods 305 and the lower fixing rod 307 are both away from each other, and the wire hook clamp 306 is connected to the main slide 302 by bolts. After installation, the position of the main slide 302 is leveled, and the position of the main slide 302 is adjusted in all directions using the vertical groove on the bracket 303 and the oblique groove on the slide plate 304, and finally the main slide 302 is installed on the bracket 303 by bolts.

[0032] Working principle: First, set up the equipment in the area to be installed, then install the auxiliary slide 301 on the side wall of the main insulator 200, and then install the main slide 302 on the side wall of the mounting base 100 through the bracket 303, and then install the upper fixing rod 305 and the lower fixing rod 307 between the two fixing clamps 308, and gather the ends of the two main slides 302 through the wire hook clamp 306, so that the two main slides 302 are fastened to the front and rear sides of the wire hook clamp 306.

[0033] After installation, the position of the main slide 302 is leveled, and the position of the main slide 302 is fully adjusted using the vertical grooves on the bracket 303 and the inclined grooves on the slide 304. Finally, the main slide 302 is installed on the bracket 303 with bolts.

[0034] When the train is running for a long time, it will rub against the main slide 302 for a long time, which may cause fluctuations in the position of the main slide 302. The position of the main slide 302 needs to be re-positioned and adjusted. Then, during maintenance, the connecting plate 405 is pulled downward to drive the two support blocks 406 to move downward. When the storage frame 401 is free from the limit of the support blocks 406, the two support blocks 406 move toward the bottom ends of the two main slides 302 respectively. The support blocks 406 squeeze the bottom ends of the main slides 302 upwards, adjust the bottom ends of the main slides 302 to a horizontal state, and then fix the main slides 302.

[0035] After leveling the position of the main slide 302, pull the pull rope 409 downward to drive the two support blocks 406 to move toward each other, then release the pull on the connecting plate 405, and the connecting plate 405 will reset upward along with the lower pressure plate 402, and then the two support blocks 406 will be stored in the storage frame 401 again, and then the pull rope 409 will be hung on the hook 410 to prevent the pull rope 409 from affecting the travel of the train when it falls naturally.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
