Description

Technical Field

[0001] This utility model relates to the field of rail transit materials technology, and in particular to a high-strength, high-conductivity aluminum alloy guide rail for rail transit. Background Technology

[0002] Urban rail transit, or subway for short, is a common public transportation tool for urban residents. It is generally built underground, with a small portion built in the air. It has advantages such as high speed, large passenger capacity, frequent service, and no traffic jams. The efficient operation of the subway relies on the coordinated operation of trains, tracks, safety facilities, and ticketing systems. And the stable and accurate stopping of trains at the platform requires compact physical components and reasonable system control.

[0003] In the rail transit industry, the performance of guide rails is crucial to the safety, stability, and power transmission efficiency of train operation. Existing rail transit guide rails have some shortcomings in terms of performance. First, the guide rail material is mostly alloy steel. In order to reduce the weight of rail transit, the rails are often set in an "I" shape. However, this structure is prone to deformation at the rail connection points due to pressure and vibration. At the same time, the sides and bottom of the rails are prone to corrosion and rust. Therefore, the rails need to be repaired and replaced frequently. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-strength, high-conductivity aluminum alloy guide rail for rail transit includes a track, a dispersing inclined surface on one side of the track, side support plates on both sides of the track, a positioning mechanism for positioning the side support plates between the side support plates and the track, a connecting groove at one end of the track, a connecting rod inside the connecting groove, a connecting mechanism for connecting and buffering adjacent tracks at the end of the track away from the connecting groove, and a sliding groove on one side of the track, a support mechanism for installing and supporting the track inside the sliding groove.

[0007] Preferably, the positioning mechanism includes multiple guide grooves formed on one side of the track, and two guide blocks are fixedly connected to one side of the support plate, with the guide blocks slidably connected within the guide grooves.

[0008] Preferably, a plurality of equally spaced support frames are fixedly connected to one side of the support plate, a plurality of equally spaced mounting grooves are opened on one side of the support plate, and a plurality of equally spaced mounting holes are opened on one side of the dispersive inclined surface, the mounting holes cooperating with the mounting grooves.

[0009] Preferably, the connecting mechanism includes a mating block fixedly connected to the end of the track away from the connecting groove. The mating block corresponds to the connecting groove. Two symmetrically arranged connecting frames are fixedly connected to one side of the mating block. A connecting hole is opened on one side of the connecting frame.

[0013] 1. This utility model is provided with structures such as a track, a dispersing slope, a connecting groove, a connecting rod, a mating block, and a connecting frame. The connecting frame and the connecting rod are slidably connected in the connecting groove. With the help of the connecting spring, the two ends of two adjacent tracks can be connected and buffered.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] Reference Figure 1-4 A high-strength, high-conductivity aluminum alloy guide rail for rail transit includes a rail 1, a dispersing inclined surface 2 on one side of the rail 1, side support plates 4 on both sides of the rail 1, a plurality of equally spaced support frames 5 fixedly connected to one side of the support plate 4, a plurality of equally spaced mounting grooves 6 opened on one side of the support plate 4, and a plurality of equally spaced mounting holes opened on one side of the dispersing inclined surface 2, the mounting holes cooperating with the mounting grooves 6.

[0022] A positioning mechanism for positioning the side support plate 4 is provided between the side support plate 4 and the track 1. The positioning mechanism includes multiple guide grooves 7 opened on one side of the track 1. Two guide blocks 8 are fixedly connected to one side of the support plate 4, and the guide blocks 8 are slidably connected in the guide grooves 7.

[0023] One end of the track 1 is provided with a connecting groove 9, and a connecting rod 10 is provided in the connecting groove 9. The end of the track 1 away from the connecting groove 9 is provided with a connecting mechanism for connecting and buffering two adjacent tracks 1. The connecting mechanism includes a mating block 12 fixedly connected to the end of the track 1 away from the connecting groove 9. The mating block 12 corresponds to the connecting groove 9. Two symmetrically arranged connecting frames 13 are fixedly connected to one side of the mating block 12. A connecting hole is provided on one side of the connecting frame 13. The connecting rod 10 mates with the connecting hole. Two symmetrically arranged connecting springs 11 are sleeved on the side wall of the connecting rod 10.

[0024] A sliding groove 16 is provided on one side of the track 1. A support mechanism for installing and supporting the track 1 is provided in the sliding groove 16. The support mechanism includes a base 14 slidably connected to one side of the track 1. A sliding frame 15 is fixedly connected to one side of the base 14. The sliding frame 15 is slidably connected in the sliding groove 16. A plurality of mounting blocks 3 are fixedly connected to one side of the track 1. A waist groove is opened on one side of the mounting block 3. A plurality of mating holes are opened on one side of the base 14. The waist groove and the mating holes are mated and connected.

[0025] When using this utility model, such as Figure 1-4 As shown, during use, the sliding frame 15 on the base 14 is first slidably installed onto the sliding groove 16 on the track 1. Then, the guide block 8 on the side support plate 4 is slidably connected into the guide groove 7, and the side support plate 4 is installed on both sides of the track 1. At this time, the inclined surface of the side support plate 4 is in contact with the dispersing inclined surface 2 on the track 1, which can distribute the force on the track 1 and avoid the problem of deformation caused by concentrated force on the track 1. At this time, the multiple support frames 5 on the side support frame 4 provide lateral support force for the side support frame 4 and the track 1. The support frames 5 and the support frame 4 are made of high-strength aluminum alloy material, which maintains the material strength while keeping it lightweight. By using a side-fitting installation method, the side of the track 1 can be protected to prevent corrosion and rust. Then, through the waist groove, mating hole, and mounting hole on the mounting block 3, the track 1, side support plate 4, and base 14 are fixed with bolts. Then, between two adjacent tracks 1, the mating block 12 and the connecting bracket 13 are inserted into the connecting groove 9. At this time, the connecting rod 10 is inserted into the connecting hole in the connecting bracket 13. At the same time, the connecting spring 11 is located between the connecting bracket 13 and the connecting groove 9 to buffer the connection between the connecting bracket 13 and the connecting groove 9. This can buffer the connection between adjacent tracks 1 when the track 1 is under pressure, and avoid the problem of track 1 deformation.
