[0027] See also Figure 1 and Figure 4 A bridge construction protection device: a first support column 1, one side of the top of the first support column 1 is rotatably connected with a connecting component 2, both sides of the top of the connecting component 2 are rotatably connected with second support columns 3, the bottom of the inner wall of the second support column 3 is slidably connected with a plug 4, the surface of the plug 4 is overlapped with a spring 5, one side of the middle of the plug 4 is fixedly connected with a limit plate 6, one side of the plug 4 is fixedly connected with a handle 7, a card slot 8 is opened on one side of the top of the first support column 1, and a slot 9 is opened on one side of the top of the first support column 1.

[0028] When the device needs to be stored, first pull the handle 7 to take the plug 4 out of the slot 9, and then rotate the first support column 1 and the second support column 3 so that the first support column 1 and the second support column 3 are rotated on both sides of the connecting component 2, thereby folding the first support column 1 and the second support column 3 in half, thereby folding the device in half for storage. When the device needs to be used, rotate the first support column 1 and the second support column 3 again, and then pull the handle 7 to put the plug 4 into the second support column 3. After rotating both to both sides of the connecting component 2, release the handle 7, and the elastic force of the spring 5 pushes the limit plate 6 to reset. The reset of the limit plate 6 drives the plug 4 to reset. After the reset of the plug 4, it is inserted into the slot 9, thereby fixing the bottom of the second support column 3 to the top of the first support column 1.

[0029] See also Figure 1 and Figure 5A bridge construction protection device: a slide groove 10 is opened on one side of the first support column 1, a slider 11 is slidably connected to the inner wall of the slide groove 10, a first connecting block 12 is fixedly connected to one side of the slider 11, and a protection rod 13 is rotatably connected to one side of the first connecting block 12.

[0030] When using the device for protection, first pull the first support column 1 and the second support column 3 on both sides of the protection rod 13. The movement of the first support column 1 and the second support column 3 drives the first connecting block 12 to move. After the first connecting block 12 moves, it drives the protection rod 13 to tilt. After the protection rod 13 tilts, it drives the first connecting block 12 on one side to slide in the slide groove 10 through the slider 11, and moves in coordination with the tilt of the protection rod 13. After the protection rod 13 tilts, it cooperates with the first support column 1 and the second support column 3 to move relatively, and the protection range of the first support column 1 and the second support column 3 is adjusted.

[0031] See also Figure 1 , Figure 2 and Figure 6 A bridge construction protection device: a second connecting block 14 is fixedly connected to the bottom of one side of the first support column 1, a first supporting rod 15 is rotatably connected to one side of the second connecting block 14, a second supporting rod 16 is slidably connected to the surface of the first supporting rod 15, a threaded groove 17 is provided on one side of the first supporting rod 15, a hand wheel 18 is threadedly connected to one side of the second supporting rod 16, a supporting plate 19 is rotatably connected to the bottom end of the second supporting rod 16, a latch 20 is fixedly connected to the bottom of the supporting plate 19, a rotating groove 21 is provided on the bottom of one side of the first support column 1, and one side of the support plate 19 is rotatably connected to the inner wall of the rotating groove 21.

[0032] After adjusting the protection range of the equipment, first rotate the support plate 19 so that one side of the support plate 19 rotates in the rotating groove 21, so that the pin 20 at the bottom of the support plate 19 is stuck in the soil layer. After the pin 20 is stuck in the soil layer, the support plate 19 is fixed. When the support plate 19 rotates, it drives the second support rod 16 to slide on the surface of the first support rod 15. After the position of the support plate 19 is fixed, use the hand wheel 18 to fix the second support rod 16 to the surface of the first support rod 15 through the threaded groove 17. After the first support rod 15 and the second support rod 16 are fixed, the support plate 19 is fixed. After the support plate 19 is fixed, the bottom pin 20 is fixed. After the pin 20 is fixed, the position of the equipment is fixed.

[0033] Working principle: when the equipment needs to be protected, rotate the first support column 1 and the second support column 3. After rotating the two to the two sides of the connecting component 2, the elastic force of the spring 5 pushes the limit plate 6 to reset. The reset of the limit plate 6 drives the plug 4 to reset. After the plug 4 is reset, it is inserted into the slot 9, thereby fixing the bottom of the second support column 3 to the top of the first support column 1, and then pulling the first support column 1 and the second support column 3 to tilt the protection rod 13. After the protection rod 13 is tilted, the protection range of the first support column 1 and the second support column 3 is adjusted, and then the support plate 19 is rotated so that the pin 20 at the bottom of the support plate 19 is stuck in the soil layer, thereby fixing the position of the first support column 1. After the first support column 1 is fixed, the position of the equipment is fixed.
