The guardrail for municipal road and bridge construction can be fixed to the two ends of the bridge and the road by the fixing components 3 without nailing the bridge deck or the road surface, thereby avoiding damaging the road condition.

[0027] like Figure 3 , Figure 4 As shown, the fixing assembly 3 includes a cylinder 301, a hollow shell 307 and two triangular plates 305. The cylinder 301 is fixedly mounted on the outer surface of the hollow shell 307 on a side away from the railing 1. A cylinder switch 303 is fixedly mounted on the side of the outer surface of the hollow shell 307 connected to the cylinder 301. The cylinder switch 303 is electrically connected to the cylinder 301. The output end of the cylinder 301 can be controlled to perform stretching movement in the horizontal direction through the cylinder switch 303. The output end of the cylinder 301 passes through the hollow shell 307 and is installed with a cross plate 304. The cylinder 301 can change the movement state of the cross plate 304. Sliders 309 are fixedly mounted on both ends of the cross plate 304. Grooves 310 are provided on the hypotenuse sides of the two triangular plates 305. The cross plate 304 is The slider 309 and the groove 310 are slidably connected to the triangular plate 305. When the cylinder 301 moves, the cross plate 304 will push the triangular plate 305 to move up and down in the vertical direction. The two triangular plates 305 are fixedly connected with a clamping plate 306 on the side away from the cylinder 301. The two side surfaces of the two triangular plates 305 close to the clamping plate 306 and in contact with the hollow shell 307 are both provided with convex strips 312. The two side surfaces of the hollow shell 307 close to the clamping plate 306 and in contact with the two triangular plates 305 are both provided with concave grooves 311. The two triangular plates 305 are slidably connected to the hollow shell 307 through the concave grooves 311 and the convex strips 312. The two triangular plates 305 penetrate the hollow shell 307 and move up and down. A support plate 308 is fixedly installed on the top of the hollow shell 307.

[0028] When in use, turn on the cylinder switch 303, the cylinder 301 will push or pull the horizontal plate 304 to do reciprocating motion, and the horizontal plate 304 is slidingly connected to the triangular plate 305, so the horizontal plate 304 will push the triangular plate 305 to move in the vertical direction. In addition, the triangular plate 305 is also slidingly connected to the hollow shell 307, and the triangular plate 305 is fixed to the clamping plate 306, so that the clamping plate 306 can clamp the original fixed objects on the bridge or road without drilling holes in the bridge deck or road surface.

[0029] like Figure 3 As shown, anti-skid pads 302 are fixedly installed on the opposite surfaces of the two clamping plates 306. The anti-skid pads 302 can make the entire fixing assembly 3 more tightly fixed to the road surface and will not easily loosen.

[0030] like Figure 3 As shown, the horizontal plate 304 can penetrate through one end of the hollow shell 307 close to the clamping plate 306, and the two clamping plates 306 are in an L-shape.

[0031] like Figure 5 As shown, the two lifting assemblies 2 each include a guardrail outer box 21 and a guardrail inner box 22. The two guardrail inner boxes 22 are arranged inside the two guardrail outer boxes 21. The two guardrail outer boxes 21 are fixedly connected through the guardrail 1. The outer surface of the guardrail outer box 21 is rotatably connected to the side away from the guardrail 1 with a handle 5. The lower end of the guardrail inner box 22 is fixedly connected to a support seat 23. The lower end of the support seat 23 is fixedly installed with a support plate 308. The support seat 23 supports the guardrail 1, the guardrail outer box 21 and the guardrail inner box 22. The interior of the guardrail inner box 22 A fixing nut 28 is fixedly installed on the upper end, and a screw 27 is threadedly connected to the fixing nut 28 in the vertical direction. The upper end of the screw 27 is fixedly connected to the base 26, and a bevel gear 25 is fixedly connected to the top of the base 26. The upper end of the bevel gear 25 is meshed with a bevel gear 1 24 on the side close to the handle 5 in the vertical direction. The bevel gear 1 24 is fixedly connected to a bearing rod 29 in the horizontal direction. The bearing rod 29 is rotatably connected to the side of the guardrail outer box 21 close to the fence 1. The handle 5 passes through the guardrail outer box 21 and is fixedly connected to the bevel gear 1 24. By rotating the handle 5, the fence 1 and the guardrail outer box 21 fixedly connected to the fence 1 can be raised and lowered.

[0032] During use, when the guardrail 1 needs to be raised or lowered, the handle 5 is rotated. When the handle 5 rotates, the bevel gear 1 24 connected thereto is driven to rotate. The rotation of the bevel gear 1 24 drives the bevel gear 25 to rotate. When the bevel gear 25 rotates, it drives the screw 27 to rotate. At this time, the rotating screw 27 will move up and down in the vertical direction, and will move the guardrail outer box 21 up and down, so that the height of the entire guardrail device can be adjusted.

[0033] like Figure 5 As shown, the guardrail outer box 21 and the guardrail inner box 22 are hollow structures.

[0034] like Figure 2 As shown, a plurality of guardrails 1 can be arranged between two guardrail outer boxes 21, and a plurality of guardrail holes 4 are evenly spaced in the vertical and horizontal directions on the outer surface of the guardrail 1. The guardrail holes 4 can facilitate pedestrians and drivers to observe the vehicle conditions on the road, and the arrangement of bridges and roads of different widths and lengths can also be achieved by the number of guardrails 1 set.

[0035] like Figure 2 As shown, three supporting protrusions 11 and concave grooves 12 are equidistantly arranged on the outer surfaces of the front and rear sides of the guardrail 1 in the vertical direction. The two guardrails 1 are slidably connected by the supporting protrusions 11 and the concave grooves 12. The supporting protrusions 11 are snapped into the concave grooves 12. The two guardrails 1 are slidably connected by the supporting protrusions 11 and the concave grooves 12, and the lengths of the two guardrails 1 can be adjusted by the supporting protrusions 11 and the concave grooves 12. In addition, the stability between the railings can be increased to prevent deformation due to vehicle collision.

[0036] Working principle: When in use, the fixing component 3 changes the movement state of the horizontal plate 304 through the power provided by the cylinder 301. Since the triangular plate 305 is slidably connected to the horizontal plate 304, and the triangular plate 305 is also slidably connected to the hollow shell 307, the horizontal plate 304 will push or stretch the triangular plate 305 to move in the vertical direction, and the splint 306 is fixed on the triangular plate 305, so that the opening and closing of the splint 306 can be controlled to realize the installation of the fixing component on the bridge deck or road surface.

[0037] In addition, when the height of the guardrail needs to be adjusted, the handle 5 is rotated. The rotation of the handle 5 can drive the bevel gear 1 24 fixedly connected thereto to rotate. Since the bevel gear 1 24 is meshingly connected with the bevel gear 25, the bevel gear 25 will rotate together. The screw 27 is threadedly connected with the fixing nut 28, and the fixing nut 28 is fixed on the guardrail inner box 22. When the bevel gear 25 rotates, the screw 27 fixedly connected to the bevel gear 25 will rise or fall, so that the height of the entire guardrail can be adjusted.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
