[0021] Please see Figure 1-4 This utility model provides the following technical solution: a bridge construction safety railing, comprising a first metal frame 1, a first barrier net 14 fixedly installed inside the first metal frame 1, a text panel 5 movably installed on the front of the first barrier net 14, a metal support plate 2 fixedly installed at the bottom of the first metal frame 1, a receiving plate 9 fixedly installed on the lower surface of the metal support plate 2, a receiving frame 24 fixedly installed at the bottom of the receiving plate 9, a first drive shaft 16 fixedly installed inside the receiving frame 24, a first movable leg 17 movably installed on the surface of the first drive shaft 16, and the other end of the first movable leg 17 being movable. A second drive shaft 18 is installed, and a second movable leg 19 is movably installed on the surface of the second drive shaft 18. A support column 13 is fixedly installed on the lower surface of the receiving plate 9, and a fixing plate 11 is fixedly installed at the lower end of the support column 13. A second metal frame 4 is movably installed on both sides of the first metal frame 1. A fluorescent lamp 6 is movably installed on the top of the first metal frame 1 and the second metal frame 4. A second barrier net 3 is fixedly installed on the inner side of the second metal frame 4, and a connecting plate 7 is fixedly installed on the outer side of the second metal frame 4. A hole is opened on the surface of the connecting plate 7, and a first connecting block 7 is movably installed in the hole.

[0022] Working principle: The bottom of the first metal frame 1 has a metal support plate 2 fixedly installed on both sides with symmetrical holes. These holes can accommodate second connecting blocks 15 to connect two different safety railings. A first barrier net 14 is fixedly installed inside the first metal frame 1. Fluorescent lights 6 are movably installed on the top of the first metal frame 1 and the second metal frame 4. At night, the fluorescent lights 6 emit light to prevent pedestrians from accidentally entering the construction site. A text board 5 is installed inside the first metal frame 1, movably connected to the first barrier net 14. The text board 5 can remind pedestrians of the construction progress. Second metal frames 4 are movably installed on both sides of the first metal frame 1. A second connecting block 15 is fixedly installed inside the second metal frame 4. The second barrier net 3, the first barrier net 14, and the second barrier net 3 are used to prevent outsiders from entering. A connecting plate 7 is fixedly installed on the outside of the second metal frame 4. The connecting plate 7 has holes, and a first connecting block 7 is movably installed on the holes. The first connecting block 7 can connect two different guardrails, or it can be removed to push open the second metal frame 4 to allow workers to pass through. A receiving plate 9 is fixedly installed at the bottom of the metal support plate 2. A receiving frame 24 is fixedly installed at the bottom of the receiving plate 9. A hole is opened on one side of the receiving plate 24. The second barrier plate 25 inside the hole can fix the first movable leg 17 when the safety guardrail is moved. A first drive shaft 16 is fixedly installed on the inside of the receiving frame 24. A first movable leg 17 is movably mounted on the surface of the safety railing. A second movable leg 19 is movably mounted on the other end of the first movable leg 17. The second movable leg 19 and the first movable leg 17 are movably connected by a second drive shaft 18. A stop bar 22 is fixedly mounted on one end of the second movable leg 19. A spring is fixedly installed inside the stop bar 22. When the safety railing needs to be moved, the stop bar 22 can be pushed into the groove in the first movable leg 17, thereby fixing the second movable leg 19. When the safety railing does not need to be moved, the first stop plate 23 on one side of the first movable leg 17 can be lowered, causing the spring in the stop bar 22 to contract and thus push the stop bar 22 out of the groove. A third drive shaft 20 is movably mounted on one end of the second movable leg 19. Wheels 21 are fixedly installed on both sides of the drive shaft 20. The extended first movable leg 17 and second movable leg 19 will cause the wheels 21 to support the ground. The wheels 21 in contact with the ground will make the safety railing easier to move. A support column 13 is fixedly installed at the bottom of the support plate 9. A fixing plate 11 is fixedly installed at the bottom of the support column 13. Fixing screws 10 are spirally installed on the surface of the fixing plate 11. The fixing screws 10 are spirally connected to the ground. The safety railing connected to the ground will not be affected by wind or other factors. The surfaces of the first metal frame 1, metal support plate 2, second metal frame 4, support plate 9, support column 13 and second connecting block 15 are all coated with anti-rust coating to prevent damage caused by river water erosion.

[0023] In one aspect of this embodiment, four fixing screws 10 evenly distributed on the fixing plate 11 can fix the safety railing to the ground to avoid unnecessary movement caused by external forces. The symmetrical holes on both sides of the metal support plate 2 can be used by the second connecting block 15 to fix two different safety railings through the holes, so that the distance between the safety railings can be extended to protect more construction site facilities.

[0024] In one aspect of this embodiment, a third drive shaft 20 is movably mounted on the other end of the second movable leg 19. Two rotating wheels 21 are fixedly mounted on the surface of the third drive shaft 20. The rotating wheels 21 can be brought into contact with the ground by the tension between the first movable leg 17 and the second movable leg 19, which can make the safety railing move more effortlessly. When not moving, the movable leg can be folded so as not to hinder its operation. The front of the receiving plate 24 has a hole. When it is necessary to move the safety railing, the second blocking plate 25 in the hole can be lowered to fix the first movable leg 17 and prevent it from moving randomly.

[0025] In one aspect of this embodiment, a stop bar 22 is fixedly installed at one end of the second movable leg 19. When preparing to move and install the guardrail, when the pressed stop bar 22 reaches the groove, the spring inside it will push the stop bar 22 into the groove in the first movable leg 17. At the same time, the spring inside the stop bar 22 will make the stop bar 22 tightly fixed in the groove, thereby preventing the second movable leg 19 from folding when the safety guardrail is moved. When preparing to fix the safety guardrail, pushing the first stop plate 23 on one side of the first movable leg 17 can push the stop bar 22 out of the groove, thereby folding the second movable leg 19. The surfaces of the first metal frame 1, metal support plate 2, second metal frame 4, receiving plate 9, support column 13, second connecting block 15, first movable leg 17 and second movable leg 19 are all provided with anti-rust coating, which can prevent corrosion from the external environment and increase their service life.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
