[0002] Railway track laying vehicles are specialized engineering vehicles used in railway construction to lay steel rails and track panels. Their core function is to efficiently complete the transportation and laying of track materials. During operation, railway track laying vehicles need to be equipped with a variety of warning devices to ensure construction safety, including mobile stop signs, speed reduction signs, and terminal signal signs. These are made of aluminum plates or reflective materials, and protective signal lights are required for nighttime operations.

[0003] The following problems exist in the application of external warning devices for railway track laying vehicles on the market: When using traditional external warning devices for railway track laying vehicles, the warning devices are usually directly welded to the outside of the track laying vehicle. When the internal warning plate structure of the warning device is damaged, the entire warning structure can only be replaced, which is time-consuming and laborious. Therefore, there is no externally mounted warning structure installed during use. Utility Model Content

[0027] like Figure 1-6As shown, this utility model discloses an external warning device for railway track laying vehicles, comprising a warning frame 1 and a warning plate 9. The warning plate 9 is installed inside the warning frame 1. The top of the warning frame 1 is connected to a strip plate 2 via a pivot. A base 10 is provided on the back of the warning frame 1. A first hanging rod 12 is provided on the top of the base 10. A hanging plate 14 is provided on the side of the first hanging rod 12. A second hanging rod 13 is installed on the other side of the hanging plate 14. An internal threaded groove 15 is formed inside the second hanging rod 13. A compression screw 16 is threaded into the internal threaded groove 15. A rubber ball 17 is provided at the bottom of the compression screw 16. A limiting groove 20 is formed on the inner side of the second hanging rod 13. A limiting ring 18 is installed inside the limiting groove 20. A rubber rod 19 is provided on the side of the limiting ring 18. By installing the first hanging rod 12 and the second hanging rod 13 on the back of the warning frame 1, Inside the second hanging ring, there is a compression screw 16 and a rubber ball 17. Inside the second hanging ring, there is a limiting ring 18 and a rubber rod 19. First, the warning plate 9 is initially installed inside the warning frame 1, and the external fasteners are tightened to fix it. The first hanging rod 12 and the second hanging rod 13 are removed, and the middle hanging plate 14 is installed on the outside of the line laying vehicle. Then, the compression screw 16 inside the second hanging rod 13 is directly tightened to press the bottom rubber ball 17 downwards. At the same time, the rubber rod 19 on the side of the limiting ring 18 is squeezed outwards, thereby installing and fixing the external warning device on the outside of the line laying vehicle. It is more time-saving and labor-saving. The rubber rods 19 are symmetrically distributed. A transparent plate 4 is installed on the outside of the warning frame 1. Due to the installation of the transparent plate 4, it is convenient to observe the warning plate 9 inside the warning frame 1.

[0028] The outer sleeve of the first hanging rod 12 is a collar 21. The side of the collar 21 is provided with a horizontal plate 22. The side of the base 10 is provided with a connecting plate 11. The outer side of the horizontal plate 22 is connected with a reinforcing rib 23. The reinforcing rib 23 is distributed at equal intervals. The connection strength between the first hanging rods 12 can be improved by installing the reinforcing rib 23.

[0029] The inner side of the strip plate 2 is provided with a sealing plate 3, the side of the strip plate 2 is provided with a top plate 5, and the outer side of the warning frame 1 is provided with a bottom plate 6. Because of the sealing plate 3, the junction between the warning frame 1 and the strip plate 2 can be sealed.

[0030] The top plate 5 has a fastening screw 7 inside, which passes through the bottom plate 6. The fastening screw 7 is connected to the fastening nut 8 by external thread. The installation of the fastening screw 7 and the fastening nut 8 makes it easy to install and fix the strip plate 2 on the top of the warning frame 1.

[0031] The warning frame 1 has a compression plate 26 inside, which is located at the bottom of the warning plate 9. The bottom of the compression plate 26 has a threaded ring 27. The bottom of the warning frame 1 has a circular hole 28, and the threaded ring 27 passes through the inside of the circular hole 28. The circular hole 28 makes it easy to install the threaded ring 27 at the bottom of the compression plate 26 inside.

[0032] The external mounting of the warning frame 1 is a threaded seat 24. The threaded seat 24 is threadedly connected to the threaded tie rod 25. The threaded tie rod 25 is threadedly connected to the threaded ring 27. The installation of the threaded seat 24 facilitates the installation of the unused threaded tie rod 25.

[0033] The working principle of this external warning device for railway track laying vehicles is as follows: When using the device, the top of the warning frame 1 is first connected to the strip plate 2 via a pivot. A sealing plate 3 is provided on the inner side of the strip plate 2, and a transparent plate 4 is installed on the side of the warning frame 1 to facilitate observation of the internal warning plate 9. To install the warning frame 1, a first hanging rod 12 and a second hanging rod 13 are installed on the back of the warning frame 1. A compression screw 16 and a rubber ball 17 are provided inside the second hanging ring. The internal limiting groove 20 is provided, and the limiting groove 20 is provided with a limiting ring 18 and a rubber rod 19. First, the warning plate 9 is initially installed inside the warning frame 1. Then, the strip plate 2 is pinched and the sealing plate 3 is embedded inside the warning frame 1. Next, the fastening screw 7 is taken out and passed through the top plate 5 and the bottom plate 6. Then, the fastening nut 8 is tightened to assemble the strip plate 2 and the warning frame 1. After that, the first hanging rod 12 and the second hanging rod 13 are pinched off and the middle hanging plate 14 is installed on the outside of the laying vehicle. The subsequent tightening is done directly. The compression screw 16 inside the second hanging rod 13 presses the rubber ball 17 at the bottom downwards, simultaneously causing the rubber rod 19 on the side of the limiting ring 18 to be squeezed outwards, thereby installing and fixing the external warning device to the outside of the laying vehicle. This process is repeated twice. This method is simpler to operate and saves time and effort. Furthermore, a collar 21 is fitted onto the outside of the first hanging rod 12. A horizontal plate 22 is provided on the side of the collar 21, and reinforcing ribs 23 are installed on the outside of the horizontal plate 22 to raise its height. 2. The connection strength between the two. Finally, when the staff needs to replace the warning plate 9, turn the fastening nut 8 in the opposite direction, take the fastening screw 7 out from inside the top plate 5 and bottom plate 6, hold the threaded pull rod 25 and take it out from inside the threaded seat 24, directly assemble the threaded pull rod 25 with the threaded ring 27, and then directly push the threaded pull rod 25 to move the top extrusion plate 26 upward. This can drive the warning plate 9 to be replaced. Moreover, the operation is simple. The replacement is to directly reinstall the threaded pull rod 25 inside the threaded seat 24.
