[0028] Example 1

[0029] like Figure 1-3 The portable warning sign device for railway operations shown includes two rotatably connected back plates 1 and a detachably connected warning sign 5. A pair of reinforcing panels 2 are also provided on the side of the back plate 1 away from the warning sign 5. A hinge structure 8 is provided between the paired reinforcing panels 2. Preferably, the hinge structure 8 in this embodiment is a hinge. The reinforcing panels 2 fixed to the surface of the back plate 1 can drive the back plate 1 to rotate around the hinge. Multiple sets of limiting clips 12 are also provided on the surface of the reinforcing panels 2. Preferably, the limiting clips 12 in this embodiment are spring clips. Four sets of spring clips are provided, specifically arranged around the outer perimeter of the reinforcing panels 2, and adjacent limiting clips 12 are symmetrically arranged along the axis of symmetry of the reinforcing panels 2. In addition, the surface of the back plate 1 is provided with openings that cooperate with the hanging posts 501 on the surface of the warning sign 5. The number of openings is the same as the number of hanging posts 501. The hanging posts 501 on the surface of the warning sign 5 pass through the openings on the surface of the back plate 1 and are fixed and limited by the limiting clips 12.

[0030] Please refer to the appendix. Figure 1-3 A rotating panel 3 is also provided on the surface of the reinforced panel 2. The rotating panel 3 is connected to the reinforced panel 2 by a rotating seat 9. The rotating seats 9 are arranged in pairs. In the vertical direction, the paired rotating seats 9 are located on the same straight line. The bottom of the rotating seat 9 is fixed to one of the panel surfaces of the reinforced panel 2. A positioning seat 10 is also fixedly provided on the surface of the other panel of the reinforced panel 2. A positioning pin 1001 is inserted inside the positioning seat 10. The positioning pin 1001 can move up and down in the vertical direction to position the rotating panel 3. The rotating panel 3 can rotate around the rotating seat 9 and the reinforced panel 2.

[0031] Please refer to the appendix. Figure 1-4The surface of the rotating panel 3 is provided with a foldable fixing bracket 4. Preferably, the fixing bracket 4 in this embodiment is L-shaped. The L-shaped fixing bracket 4 is composed of a long side and a short side perpendicularly connected by a rotating hinge. The two sides can rotate by rotating the hinge. In addition, a diagonal brace is provided between the two sides. One end of the diagonal brace is rotatably connected to the tail of the short side, and the other end can slide on the long side. When the fixing bracket 4 is unfolded, the diagonal brace provides bending support, improves the structural rigidity and resistance to external forces of the overall bracket, and forms a right triangle with the long side, the short side and the diagonal brace.

[0032] It is worth noting that a gourd hole 301 and a limiting hole 302 are also provided inside the rotating panel 3. In this embodiment, there are two sets of gourd holes 301 and the limiting hole 302 is located in the middle of adjacent gourd holes 301. The gourd holes 301 are used in conjunction with the bolt groups 7 on both sides of the U-shaped plate 6, and the limiting hole 302 is used in conjunction with the T-shaped pin 11. This can limit the relative movement between the gourd holes 301 and the bolt groups 7, thereby ensuring the stability during operation.

[0033] Please refer to the appendix. Figure 1 A U-shaped plate 6 is fixedly installed on the upper surface of the fixed bracket 4. The bottom surface of the U-shaped plate 6 is fixedly connected to the upper surface of the fixed bracket 4. A bolt group 7 is provided inside the U-shaped plate 6. The bolt group 7 is used in conjunction with the hoist hole 301. T-shaped pins 11 are also provided on both sides of the U-shaped plate 6. The two ends of the T-shaped pins 11 pass through the two sides of the U-shaped plate 6 and are used in conjunction with the limiting hole 302. The T-shaped pins 11 can move and rotate inside the U-shaped plate 6.

[0034] Please refer to the appendix. Figure 1-3 Before use, the back panel 1, the reinforcing panel 2, and the fixed bracket 4 are all folding devices. The rotating panel 3 is located on one side of the reinforcing panel 2. The back panel 1 and the reinforcing panel 2 are unfolded to a flat state, so that the left and right sides of the back panel 1 and the reinforcing panel 2 are fully opened through the hinge structure 8. The rotating panel 3 is rotated so that the two sides of the rotating panel 3 are located on the two sides of the reinforcing panel 2 respectively. The positioning pin 1001 is moved downward and the bottom of the positioning pin 1001 is inserted into the interior of the rotating panel 3. The fixed bracket 4 is unfolded, and the long side of the fixed bracket 4 rotates relative to the short side. The diagonal brace moves on the surface of the long side until the two sides are at right angles. The unfolded fixed bracket 4 is fixed in the corresponding position with straps. The unfolded back plate 1 structure is installed on the fixed bracket 4. During the installation process, the bolt group 7 on one side of the U-shaped groove enters into the gourd hole 301 on the surface of the rotating panel 3. The T-shaped pin 11 moves in the direction of the rotating panel 3 and enters into the limiting hole 302, completing the installation process of the back plate 1. Then, the warning sign 5 is installed on the surface of the back plate 1, so that the hanging post 501 on the surface of the warning sign 5 passes through the opening, and the hanging post 501 of the warning sign 5 is restricted by the limiting clip 12.

[0035] After completing the construction work, rotate the limiting clip 12 to release the hanging post 501 of the warning sign 5 from the limitation of the limiting clip 12, remove the warning sign 5, move the T-pin 11 away from the rotating panel 3, move the back plate 1 and the reinforcing panel 2 upward to release the gourd hole 301 from the bolt group 7, remove the back plate 1 and the reinforcing panel 2, move the positioning pin 1001 away from the rotating panel 3, rotate the rotating panel 3 so that the rotating panel 3 is on the surface of the reinforcing panel 2 on one side, fold the back plate 1 and the reinforcing panel 2, untie the straps and remove the fixing bracket 4, and fold the fixing bracket 4 to complete the storage after the construction work.

[0036] Example 2

[0037] When conducting regular inspections and maintenance on some railway components, the maintenance time span is relatively long. If the maintenance work is carried out for too long, it will directly affect the operation of the train. Therefore, it is necessary to coordinate the maintenance work time to minimize the impact on the normal operation of the train.

[0038] See attached document Figure 1-6 Unlike Embodiment 1 described above, this embodiment divides the warning sign 5 into multiple areas. Preferably, this embodiment divides it into two areas: a maintenance area and an operation area. The background color of the warning sign 5 in the two areas is different: red for the maintenance area and green for the operation area. A ring frame 13 is fixedly installed between the warning sign 5 and the back plate 1. The outer side of the ring frame 13 is provided with hanging holes 1301 around the back plate 1. The hanging holes 1301 correspond to the positions of the limiting clips 12. A detachable pointing arrow is provided in the middle of the ring frame 13, and the pointing arrow can rotate around the ring frame 13.

[0039] Unlike Embodiment 1, this device removes the directional arrow in the middle of the ring frame 13 during use. The hanging post 501 on the surface of the warning sign 5 passes through the hanging hole 1301 and the opening on the surface of the back plate 1 and is fixedly connected to the limiting clip 12. The directional arrow is then installed. During maintenance and construction, the arrow is adjusted to the maintenance area. During rest, the directional arrow is adjusted to the operating area. Furthermore, by using the ring frame 13, more than two function display areas can be added for easy switching.

[0040] In this embodiment, the structure provides a warning by adjusting the direction of the directional arrows over a long period of maintenance work, thereby reducing the impact on train operation during maintenance.
