Description

Technical Field

[0001] This utility model relates to the field of track monitoring technology, specifically a foreign object intrusion monitoring device for rail transit lines. Background Technology

[0002] Rail transit refers to a type of transportation vehicle or system that requires operating vehicles to run on specific tracks. The most typical rail transit system is the railway system composed of traditional trains and standard railways. Rail transit, such as conventional railways, high-speed railways, light rail, and subways, plays an important role in the transportation field. In rail transit systems, inspecting railway lines and analyzing whether there are any foreign objects encroaching on the tracks is a necessary way to ensure the safety of rail transit.

[0003] Chinese patent CN221809765U discloses a foreign object intrusion monitoring device for rail transit lines. By setting up an installation mechanism and a monitoring mechanism, it is easy to quickly assemble and disassemble the monitoring device and expand the monitoring range. By setting up an energy-saving mechanism, it can absorb solar energy to power the device, making the device more energy-efficient during operation and suitable for widespread use.

[0004] While the aforementioned solutions allow for quick assembly and disassembly of the monitoring device via an installation mechanism, the fact that the monitoring radar spans multiple tracks via fixed poles necessitates maintenance workers climbing the poles or using ladders on the tracks to disassemble the radar is inconvenient and poses safety hazards. Therefore, we provide a foreign object intrusion monitoring device for rail transit lines to address these issues. Utility Model Content

[0019] (iii) Beneficial effects:

[0020] Compared with existing technologies, this foreign object intrusion monitoring device for rail transit lines has the following advantages:

[0021] This invention uses a motor-driven screw to rotate, which in turn moves a slider along a groove, thereby enabling the lateral movement of the monitoring radar. This allows maintenance personnel to move the monitoring radar to the support frame and safely access the maintenance position using a ladder, eliminating the need for direct work at height. This improves the convenience and efficiency of maintenance work, significantly reduces the risks associated with working at height, and ensures the personal safety of personnel.

[0026] 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.

[0027] like Figure 1-3 As shown, this utility model provides a technical solution: a foreign object intrusion monitoring device for rail transit lines, including a fixed frame 1, a mounting base 15, and a movable component.

[0028] A shielding plate 7 is provided above the fixed frame 1. Two sets of support blocks 6 are fixedly connected to the shielding plate 7, and the bottom end of the support blocks 6 is fixedly connected to the fixed frame 1. The structure on the fixed frame 1 is shielded by the shielding plate 7.

[0029] Both ends of the fixed frame 1 are fixedly connected to the support frame 2. The fixed frame 1 has two sliding grooves 10, and each sliding groove 10 has a slider 11 slidably connected to it.

[0030] The bottom surfaces of the two support frames 2 are fixedly connected to the base 3. The fixed frame 1 is supported above the track by the two support frames 2, while the support frames 2 are fixed to the ground by the base 3. The two support frames 2 are provided with ladders 5 on their opposite sides. The two ladders 5 are fixedly connected to the connecting blocks 4, and one end of the connecting blocks 4 is fixedly connected to the support frame 2. The ladders 5 are fixed to the support frames 2 by the connecting blocks 4. When maintenance is required, the ladders 5 can be climbed to the fixed frame 1.

[0031] The mounting base 15 is provided with a connecting component, and the mounting base 15 can be detachably mounted on the slider 11 through the connecting component. The mounting base 15 is also equipped with a monitoring radar 16, which can be mounted on the mounting base 15 with bolts.

[0032] The connecting assembly includes a connecting plate 12, on which a positioning groove 13 is provided. A positioning block 14 is fixedly connected to the bottom surface of the slider 11, and the positioning block 14 is inserted into the positioning groove 13. When installing the connecting plate 12, the connecting plate 12 needs to be installed on the positioning block 14 through the positioning groove 13.

[0033] Two storage cavities 17 are provided in the connecting plate 12. A movable plate 19 is slidably connected in each of the two storage cavities 17. A guide rod 18 is fixedly connected to the opposite end of each of the two movable plates 19. The guide rod 18 passes through the connecting plate 12 and is fixedly connected to a fixed plate 21. A spring 20 is sleeved on the guide rod 18. A movable block 23 is installed on the fixed plate 21. Movable grooves 25 are provided on both sides of the fixed frame 1, and the movable block 23 is slidably connected in the movable grooves 25.

[0034] When installing the connecting plate 12, the fixed plate 21 needs to be moved by the guide rod 18 to move the moving plate 19 and compress the spring 20. Then, the connecting plate 12 is installed on the positioning block 14 through the positioning groove 13. Under the elasticity of the spring 20, the moving plate 19 is reset, thereby inserting the moving block 23 on the fixed plate 21 into the moving groove 25, thus completing the limiting of the connecting plate 12.

[0035] A roller 24 is rotatably connected to the movable block 23, and the roller 24 abuts against the inner wall of the movable groove 25, so that when the movable block 23 slides in the movable groove 25, the roller 24 rolls on the inner wall of the movable groove 25.

[0036] A handle 22 is fixedly connected to the fixed plate 21, which facilitates pushing and pulling the fixed plate 21.

[0037] The moving component is mounted on the fixed frame 1 and is used to drive the monitoring radar 16 to move on the fixed frame 1 via the slider 11. The moving component includes a motor 8 mounted on the fixed frame 1, and a screw 9 is mounted on the output shaft of the motor 8. The screw 9 is rotatably connected to the slide groove 10, and the slider 11 is threadedly connected to the screw 9.

[0038] When the monitoring radar 16 needs maintenance, the motor 8 can be started, causing the output shaft of the motor 8 to drive the screw 9 to rotate, and the slider 11 to slide inside the slide groove 10. The mounting base 15, through the connecting assembly, follows the slider 11 and moves the monitoring radar 16 to the support frame 2, allowing workers to climb the ladder 5 to a high place to directly maintain the monitoring radar 16.
