Description

Technical Field

[0001] This utility model relates to the field of rail transport bracket technology, and in particular to a rail transport bracket for mountainous areas. Background Technology

[0002] A rail transport bracket is a device or structure used in a rail transport system to support, fix, and carry transported objects (such as trains, mine cars, etc.). Publication No. CN113620010A discloses a transport bracket for transporting objects, comprising: a chassis defining a main axis of the transport bracket and configured to run on a track system having a first track and a second track parallel to the first track, and having a first chassis unit for the first track and a second chassis unit for the second track; and a transport structure for at least one object defining a transport plane. The first chassis unit is rotatably fixed to the transport structure such that the first chassis unit cannot tilt relative to the transport plane along the direction of the main axis. The second chassis unit is rotatably connected to the transport structure such that the second chassis unit can tilt relative to the transport plane about an tilting axis along the direction of the main axis. In practical applications, it has some shortcomings. The uneven terrain in mountainous areas makes it impossible to install the tracks perfectly horizontally. When the bracket travels too fast and there are large bumps in front, the bracket is prone to derailment. In addition, the track installation cannot guarantee that the spacing is exactly the same. When the track spacing is narrow during the bracket's travel, the rollers will be squeezed. Over time, the rollers and brackets are prone to falling off, causing derailment. Improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] This utility model adopts the following technical solution: a mountain rail transport bracket, including an I-beam, with sliders slidably connected to both ends of the I-beam, a bracket fixedly installed at the bottom of the slider, a connecting plate fixedly installed at the bottom of the bracket, a groove opened inside the connecting plate, a limit plate slidably connected inside the groove, a spring groove opened inside the limit plate, a button slidably connected inside the spring groove, a first spring fixedly installed between the button and the spring groove, a roller rod rotatably connected inside the limit plate, a locking block fixedly installed at the bottom of the limit plate, a support rod slidably connected inside the slider, and a second spring sleeved on the surface of the support rod.

[0005] Preferably, the roller rod is rotatably connected to a roller, with both sides of the roller protruding beyond its center. This protrusion lowers the roller's center of gravity, enhancing the transport equipment's resistance to tilting during operation, especially at high speeds or when navigating curves. This helps maintain stability and prevents tipping. Simultaneously, the protruding sides can engage with the sides of the track, providing guidance and ensuring the roller stays on the track, reducing the risk of derailment. In some suspended rail transport systems, the protruding sides of the roller can engage with the track edge, ensuring stable operation of the transport equipment.

[0006] Preferably, one end of the second spring is fixedly mounted on the surface of the slider, and the other end is fixedly mounted on the protruding surface of the support rod. This ensures that the reaction force is directly transmitted to the main structure of the slider, preventing spring offset or twisting. This connection method allows the spring's compressive force to be fully used to buffer the longitudinal movement of the support rod, improving the stability of the bracket in complex terrain.

[0007] Preferably, the lower surface of the locking block is inclined. Here, the lower surface of the locking block is designed as an inclined surface so that when the device is placed on the track, the limiting plate can slide, causing the locking block to lock onto the track.

[0008] Preferably, the bracket is welded to the surface of the slider, and the connecting plate is welded to the surface of the bracket. Here, welding the bracket to the surfaces of the connecting plate and the slider makes the connection more secure and less prone to breakage or detachment.

[0009] Preferably, a carrying plate is fixedly mounted on the upper surface of the I-beam, and the carrying plate has connecting holes inside. These connecting holes facilitate the connection between the connecting block and the carrying plate.

[0010] Preferably, a connecting block is slidably connected inside the connecting hole. Both the surface of the carrying plate and the surface of the connecting block have screw holes, which are aligned. Bolts are threaded into the screw holes. Here, bolts and screw holes are used to secure the connected carrying plate, preventing the connecting block and the carrying plate from detaching.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by setting a limiting plate, a button, a first spring and a locking block structure, pressing the button compresses the first spring, causing the limiting plate to slide in the groove, and locking the locking block into the side of the track, thus connecting the bracket to the track and preventing the bracket from derailing due to the ruggedness of the mountain road.

[0013] 2. In this utility model, by setting a connecting hole, a connecting block and a carrying plate structure, the connecting block is slid into the connecting hole and the connecting block and the carrying plate are fixed with bolts, thus realizing the modular structure of the carrying plate, which facilitates the splicing of the carrying plates and increases the storage space.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1

[0023] Please see Figure 1-3This utility model provides a technical solution: a mountain rail transport bracket, including an I-beam 1, with sliders 2 slidably connected to both ends of the I-beam 1, a bracket 3 fixedly installed at the bottom of the sliders 2, and a connecting plate 4 fixedly installed at the bottom of the bracket 3. A groove 14 is provided inside the connecting plate 4, and a limiting plate 6 is slidably connected inside the groove 14. A spring groove 13 is provided inside the limiting plate 6, and a button 5 is slidably connected inside the spring groove 13. A first spring 12 is fixedly installed between the button 5 and the spring groove 13. A roller rod 7 is rotatably connected inside the limiting plate 6, and a roller 8 is rotatably connected to the surface of the roller rod 7. The two sides of the roller 8 protrude beyond its center, lowering the center of gravity and enhancing the anti-tilting ability of the transport equipment during operation. Especially at high speeds or when passing through curves, it helps maintain stability and prevents tipping. Simultaneously, the protruding sides cooperate with the sides of the track 20, providing guidance and ensuring the roller 8 always runs on the track 20, reducing the risk of derailment. In some suspended track 20 transportation systems, the rollers 8 protrude on both sides and can engage with the edge of the track 20 to ensure stable operation of the transportation equipment. A locking block 9 is fixedly installed at the bottom of the limiting plate 6. The lower surface of the locking block 9 is inclined. When the device is placed on the track 20, the limiting plate 6 can slide, causing the locking block 9 to engage with the track 20. A support rod 10 is slidably connected inside the slider 2. A second spring 11 is sleeved on the surface of the support rod 10. One end of the second spring 11 is fixedly installed on the surface of the slider 2, and the other end is fixedly installed on the protruding surface of the support rod 10. The second spring 11 ensures that the reaction force is directly transmitted to the main structure of the slider 2, preventing the second spring 11 from shifting or twisting. This connection method allows the compressive force of the second spring 11 to be fully used to buffer the longitudinal movement of the support rod 10, improving the stability of the bracket in complex terrain.

[0024] Example 2

[0025] Please see Figure 4 A carrying plate 15 is fixedly installed on the upper surface of the I-beam 1. A connecting hole 17 is provided inside the carrying plate 15 to facilitate the connection between the connecting block 16 and the carrying plate 15. The connecting block 16 is slidably connected inside the connecting hole 17. Screw holes 18 are provided on the surface of both the carrying plate 15 and the connecting block 16. The screw holes 18 on the carrying plate 15 and the connecting block 16 are aligned. A bolt 19 is threaded into the screw hole 18. The bolt 19 and the screw hole 18 are used to fix the connected carrying plate 15 to prevent the connecting block 16 and the carrying plate 15 from falling off.

[0026] Working principle: First, place the device on the track 20 and press button 5. Button 5 disengages from the spring groove 13, allowing the limit block to slide within the slide groove 14. The track 20 contacts the inclined surface of the locking block 9, allowing the limit block to slide within the slide groove 14. The locking block 9 engages with the protrusion of the track 20. When additional storage space is needed, the connecting block 16 can be inserted into the connecting hole 17. Align the screw hole 18 on the connecting block 16 with the screw hole 18 on the carrying plate 15, and screw the bolt 19 into the screw hole 18 to fix the carrying plate 15 and the connecting block 16. When the distance between the tracks 20 changes, the roller 8 drives the slider 2 to slide on the I-beam 1 and the support rod 10 to adjust the gap. The second spring 11 is compressed, providing an outward force to prevent uneven force caused by only one side of the roller 8 sliding on the I-beam 1.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
