Description

Technical Field

[0001] The present application relates to the field of railway level aisle protection, and in particular to a railway level aisle protection early warning device. Background Art

[0002] A railroad crossing means a railroad grade crossing or railroad grade intersection. It refers to the point where the railway line crosses the road or sidewalk at the same level, allowing vehicles and pedestrians to cross the railway tracks, and these crossings are usually marked with warning signs, railings and signals to ensure safety and prevent accidents;

[0003] A common protective device at railway crossings is a guardrail. Currently, most of these guardrails are just a simple railing. When a train is about to come, the staff will pull down the railing and remind vehicles not to move forward. However, the length of the railing is limited. When the intersection is large, there will be a large gap even if the railing is lowered. Therefore, in the later stage, when the railing is closed, some vehicles will rush through the railway crossing from the intersection where the railing cannot stop them. Utility Model Content

[0025] Embodiment 1, below is combined with the attached Figure 1-6 This application is described in further detail.

[0026] The embodiment of the present application discloses a railway flat aisle protection and warning device, including a movable vertical rod 20, a connecting rod 21 is fixed to one side of the movable vertical rod 20 by bolt threads, one end of the connecting rod 21 and one end of the extension rod 26 are both provided with a T-shaped groove 22, and the bottom of one end of the connecting rod 21 and the bottom of one end of the extension rod 26 are both fixedly provided with a limiting plate 23. When the extension rod 26 needs to be connected to the connecting rod 21, the T-shaped protrusion 24 at one end of the extension rod 26 is embedded in the T-shaped groove 22 at one end of the connecting rod 21, so that the extension rod 26 and the connecting rod 2 1, and when the T-shaped protrusion 24 is embedded in the T-shaped groove 22 at one end of the connecting rod 21, the groove 25 at the bottom of the T-shaped protrusion 24 will be engaged with the limit plate 23 at the bottom of one end of the connecting rod 21, so that the extension rod 26 is connected to the connecting rod 21, and finally the upper protective cover 30 is put on the top of the connection between the connecting rod 21 and the extension rod 26, and then the lower protective cover 31 is put on the bottom of the connection between the connecting rod 21 and the extension rod 26, so that the upper protective cover 30 and the lower protective cover 31 wrap the connection between the connecting rod 21 and the extension rod 26;

[0027] When the upper protective cover 30 is fitted with the lower protective cover 31, the U-shaped protrusion 36 on the top of the lower protective cover 31 will be embedded in the U-shaped groove 35 at the bottom of the upper protective cover 30. Finally, two bolts are taken out and passed through the U-shaped protrusion 36 and the U-shaped groove 35 to extend to the inside of the connecting rod 21 and the extension rod 26 respectively, and the upper protective cover 30 and the lower protective cover 31 are threadedly fixed at the connection between the connecting rod 21 and the extension rod 26. By connecting in this way, the extension rod 26 can be expanded later, and the extension rod 26 can also be disassembled when not in use.

[0028] The support plate 15 is fixed to the bottom of the base plate 12 by bolt threads, and the other end of the support plate 15 is fixed to the outside of the fixing column 10 by bolt threads. When the support plate 15 is threadedly fixed to the base plate 12, a triangular support is formed between the base plate 12 and the support plate 15. The warning light 13 is threadedly fixed to the bottom of the base plate 12 by bolts, and the bottom of the solar photovoltaic panel 11 is threadedly fixed to the top of the base plate 12 by bolts. The solar photovoltaic panel 11 allows the warning light 13 to be on for a long time during operation, and a reflector 14 is threadedly fixed to the outside of the fixing column 10 by bolt threads. The reflector 14 allows the fixing column 10 to be seen when a light shines at night.

[0029] Please refer to Figure 1-2 And 6, before extending the extension rod 26, the silicone column 33 can be put on the outside of the sliding rod 34, and then the two ends of the sliding rod 34 can be respectively embedded in the two sliding grooves 32, so that the sliding rod 34 is movably connected with the sliding groove 32. Similarly, when the extension rod 26 is extended, the silicone column 33 and the sliding rod 34 can also be extended synchronously. Through the silicone column 33, when the guardrail is used later, if a car fails to brake and hits the silicone column 33, the silicone column 33 can reduce the impact through its own elastic force, thereby causing little damage to the guardrail.

[0030] The fixed column 10 is hollow, and a universal wheel is threadedly mounted on the bottom of the movable vertical rod 20 by bolts, so that the movable vertical rod 20 can slide left and right inside the fixed column 10 .

[0031] Working principle and process of this utility model:

[0032] The warning light 13 is powered by the solar photovoltaic panel 11, so the battery in the warning light 13 will be fully charged, so that the warning light 13 will light up for 24 hours without interruption. At the same time, it can also be powered by connecting to a power grid, and the overall length of the guardrail can be extended or shortened as needed. When the guardrail needs to be lengthened as a whole, first, the T-shaped protrusion 24 at one end of the extension rod 26 is engaged with the T-shaped groove 22 at one end of the connecting rod 21. After the connection is completed, the upper protective cover 30 is put on the top of the connection between the connecting rod 21 and the extension rod 26.

[0033] Then, the lower protective cover 31 is put on the bottom of the connection between the connecting rod 21 and the extension rod 26, so that the connection between the connecting rod 21 and the extension rod 26 is protected, and then the upper protective cover 30 and the lower protective cover 31 are threadedly fixed to the outside of the connecting rod 21 and the extension rod 26 with two bolts respectively, so that the extension rod 26 will not fall off after being connected to the connecting rod 21. Finally, a new extension rod 26 is taken out in the same way, and the T-shaped protrusion 24 at one end of the new extension rod 26 is aligned with the T-shaped groove 22 at one end of the extension rod 26 connected to the connecting rod 21, so that the two extension rods 26 are connected in the same way, and so on.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
