[0030] 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.

[0031] Reference Figures 1-3 This utility model provides an embodiment of a single-hole double-track running rail installation bracket, including a crossbar 1. The inner side wall of the crossbar 1 is provided with an oblong hole to meet the needs of subway track laying machines with different spans. Compared with traditional running rail brackets, it does not require drilling holes in the shield wall and existing structure, reducing damage to the original structure and ensuring the waterproofness of the shield section. A connecting frame 2 is fixedly connected to the side wall of the crossbar 1. A connecting block 9 is inserted into the inside of the connecting frame 2. A connecting plate 3 is fixedly connected to the side wall of the connecting block 9. A connecting groove adapted to the size of the connecting block 9 is provided inside the connecting frame 2 to improve the connection stability between the connecting plate 3 and the crossbar 1.

[0032] Furthermore, an adjusting cylinder 4 is hinged to the side wall of the connecting plate 3, and an adjusting rod 5 is connected to the internal thread of the adjusting cylinder 4. The inner side wall of the adjusting cylinder 4 is provided with an internal thread, and the outer surface of the adjusting rod 5 is provided with an external thread that matches the size of the internal thread. A stabilizing mechanism 8 is provided on the side wall of the adjusting rod 5, and a support plate 6 is connected to the end of the adjusting rod 5. The support plate 6 provides support for the side wall of the track. The end of the adjusting rod 5 is connected to the support plate 6 by bolts, and a buffer assembly 7 is provided on the inner side wall of the support plate 6.

[0033] Reference Figures 3-4The stabilizing mechanism 8 includes a stabilizing rod 81. The end of the stabilizing rod 81 is fixedly connected to the side wall of the adjusting rod 5. The end of the stabilizing rod 81 is elastically connected to a stabilizing block 83 through a return spring 82. Pulling the stabilizing block 83 stretches the return spring 82, causing it to deform. During reset, the rebound of the return spring 82 causes the stabilizing block 83 to slide and reset. The stabilizing block 83 is slidably connected to the outer surface of the stabilizing rod 81. A sliding hole is provided inside the stabilizing block 83, allowing it to slide on the outer surface of the stabilizing rod 81. A stabilizing hole is provided on the side wall of the stabilizing block 83. The stabilizing hole penetrates the bolt and contacts the side wall of the support plate 6. The stabilizing hole protects the bolt from falling off due to vibration.

[0034] Reference Figures 1-2 The buffer assembly 7 includes a fixed rod 71, the end of which is fixedly connected to the inner wall of the support plate 6. A limiting groove is formed on the side wall of the support plate 6, allowing for a stable connection between the fixed rod 71 and the support plate 6. A movable block 73 is slidably connected to the outer surface of the fixed rod 71, and the movable block 73 is slidably connected within the limiting groove. The movement of the fixed rod 71 drives the movable block 73 to slide within the limiting groove. The side wall of the movable block 73 is elastically connected to the inner wall of the support plate 6 via a buffer spring 72. Next, during the sliding process of the moving block 73, the buffer spring 72 is compressed, causing the buffer spring 72 to deform. When resetting, the rebound of the buffer spring 72 drives the moving block 73 to slide and reset. A buffer rod 74 is hinged to the side wall of the moving block 73, and a buffer plate 75 is hinged to the end of the buffer rod 74. A buffer groove adapted to the size of the buffer plate 75 is opened on the side wall of the support plate 6. The buffer plate 75 is made of rectangular hard rubber, which plays a stable fitting role to the side wall of the track, and at the same time plays a partial buffering and protection role against the vibration transmitted to the support during the use of the track.

[0035] Working principle: When in use, after placing the crossbar 1 in the required position, fix the bolt in the internal slotted hole according to the required size. Then, insert the connecting plate 3 and the connecting block 9 into the inside of the connecting frame 2. At the same time, use the bolt to connect the connecting plate 3 to the side wall of the crossbar 1. Adjust the length of the adjusting cylinder 4 and the adjusting rod 5 according to the supported track. When adjusting, rotate the adjusting rod 5 and slide it inside the adjusting cylinder 4. After adjusting to the appropriate position, connect the adjusting rod 5 to the support plate 6 with the bolt. After the connection is completed, pull the stabilizing block 83 and squeeze the return spring 82 to slide on the outer surface of the stabilizing rod 81. Then, insert the stabilizing hole inside the stabilizing block 83 into the end of the bolt. At the same time, release the pull on the stabilizing block 83. The rebound of the return spring 82 will cause the stabilizing block 83 to return and slide on the outer surface of the stabilizing rod 81. The stabilizing hole is inserted into the bolt to meet the stability during the bolt connection process.

[0036] By using the buffer plate 75 to support the side wall of the track, the track vibrates after the vehicle passes over it. The vibration of the track drives the buffer plate 75, which in turn drives the connecting buffer rod 74 and the moving block 73 to move. During the sliding process, the moving block 73 squeezes the buffer spring 72 and slides on the outer surface of the fixed rod 71, which has a buffering effect on the buffer plate 75 and improves the stability and safety of the support plate 6 during the support process.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
