At present, the subway contact rail supports are mainly connected to metal bases or cement piers. The connection methods are chemical anchor bolts or spike connections. The spike connection requires reserved spike threaded holes during the early line construction. The chemical anchor connection requires drilling holes and planting anchor bolts on the cement pier or roadbed.

[0003] When the contact rail and its ancillary equipment fail and need to be equipped with a base, the existing normal base cannot meet the needs of emergency repair and temporary restoration of traffic, and an emergency repair base needs to be installed to support the insulating bracket. The emergency repair base in the elevated section, especially at the platform position, cannot be used, and the bottom of the existing emergency repair base needs to be raised before it can be used;

A fixing block 202 is provided at the lower end of the vertical adjustment rod 2, and a thread is provided on the side of the vertical adjustment rod 2.

[0025] By lengthening the length of the vertical adjustment rod 2, the vertical adjustment rod 2 can still effectively support the emergency repair base body 1 when there is a large height difference in the elevated section of the contact rail. By customizing and enlarging the fixed block 202 at the lower end of the vertical adjustment rod 2 that contacts the ground, compared with the traditional fixed block 202, the enlarged fixed block 202 can effectively reduce the instability of the emergency repair base body 1 in the elevated section due to the repair base being too high from the ground, so that the emergency repair base body 1 can meet the repair needs of the elevated section of the contact rail, further improving the applicability.

[0026] At least two horizontal adjustment rods 4 are provided, and the horizontal adjustment rods 4 are perpendicular to the side of the side plate 102. The multiple horizontal adjustment rods 4 are in parallel. The side of the horizontal adjustment rod 4 is provided with a thread. One end of the horizontal adjustment rod 4 is provided with a second limit block 401. From the second limit block 401 to the other end of the horizontal adjustment rod 4, a splint 402, a first adjusting nut 403 and a second adjusting nut 404 are sequentially provided.

[0027] The telescopic clip nut 3 includes a guard plate 301, a closing plate 302, a spring 303, a positioning nut 304, a button 305 and a pressing block 306. The closing plate 302, the spring 303 and the positioning nut 304 are at least two, and the two closing plates 302 are respectively located above and below the guard plate 301. One end of the spring 303 contacts the inner side of the guard plate 301, and the other end of the spring 303 contacts the side of the positioning nut 304. The button 305 is connected to the pressing block 306, and the positioning nut 304 is It is threadedly connected to the vertical adjustment rod 2, a first through hole 3011 is arranged on the side of the guard plate 301, the button 305 is located inside the first through hole 3011, a slide groove 3021 is arranged on the side of the closing plate 302, a second through hole 3022 is arranged inside the closing plate 302, a protrusion 3042 is arranged on one side of the positioning nut 304, a top block 3041 is arranged on the other side of the positioning nut 304, the protrusion 3042 is located inside the slide groove 3021, and the pressing block 306 is in contact with the top block 3041.

[0028] By replacing the nut that limits the position of the vertical adjustment rod 2 in the repair base body 1 with a telescopic clip nut 3, when the personnel directly presses the button 305 on the telescopic clip nut 3, the pressure block 306 squeezes the top block 3041 to both sides, so that the positioning nut 304 is no longer connected to the vertical adjustment rod 2, and the telescopic clip nut 3 can be driven to move on the vertical adjustment rod 2; when the personnel releases the button 305, the spring 303 squeezes the positioning nut 304 toward the center of the telescopic clip nut 3, so that the positioning nut 304 is connected to the vertical adjustment rod 2. At this time, the telescopic clip nut 3 is fixed on the vertical adjustment rod 2, and the personnel can use the two telescopic clip nuts 3 to clamp the support plate 101 to fix the vertical adjustment rod 2 on the repair base body 1, thereby reducing the time for personnel to tighten the nuts, reducing labor costs, improving installation efficiency, and further improving the timeliness of emergency repairs.

[0029] Working principle: When a fault occurs in the equipment of the elevated section of the contact rail and it is necessary to install an emergency repair base body 1 to raise the insulating frame, first fix the support plate 101 in the emergency repair base body 1 under the insulating frame, and at the same time use the first adjusting nut 403 to limit the position of the clamping plate 402 on the horizontal adjusting rod 4 so that the clamping plate 402 clamps the rail, and then control the position of the telescopic clip nut 3 on the vertical adjusting rod 2 so that the fixed block 202 contacts the ground, and use two telescopic clip nuts 3 to clamp the support plate 101 so that the vertical adjusting rod 2 is fixed on the emergency repair base body 1, thereby meeting the maintenance needs of the elevated section of the contact rail. Compared with traditional nut fixing, the telescopic clip nut 3 reduces the time for personnel to tighten the nut, reduces labor costs, and improves installation efficiency.
