[0036] See also Figure 1-Figure 5 , the utility model provides a bridge guardrail steel structure.

[0037] A guardrail column 001 for supporting and limiting the adjusting tube 002 is installed in the middle part of the adjusting tube 002. The guardrail column 001 includes two side panels 100. A bottom plate 110 for supporting the side panels 100 is fixedly installed at the lower ends of the two side panels 100. A plurality of bolts 111 are installed on the edge of the bottom plate 110 for facilitating the installation of the guardrail column 001 on the upper end of the bridge, thereby increasing the stability of the guardrail column 001.

[0039] A plurality of limiting tubes 200 for limiting the adjustment assembly 300 are fixedly installed in the middle of the side plate 100, and the limiting tubes 200 include a fixed tube 210, and a limiting hole 211 is opened in the middle of the fixed tube 210 for the adjustment tube 002 to slide, and the cavity diameter of the limiting hole 211 is larger than the cavity diameter of the limiting hole 120.

[0040] The lower end of the fixed pipe 210 is provided with a water leakage groove 212 for rainwater to fall, so as to prevent rainwater from accumulating in the cavity of the second limiting hole 211 for a long time and being unable to disperse during the rainy season, thereby causing rust on the fixed pipe 210. The upper end of the fixed pipe 210 is provided with an operation port 213, and a limiting shaft 214 for limiting the adjustment assembly 300 is fixedly installed in the middle of the operation port 213.

[0041] The guardrail column 001 includes an adjustment component 300 for controlling the adjustment tube 002 to move left and right. The adjustment component 300 includes a vertical rod 310. A limiting hole three 311 is opened in the middle of the vertical rod 310 for cooperating with the limiting shaft 214 to support the vertical rod 310. Both sides of the hole cavity of the limiting hole three 311 are processed into arc surfaces 312 to facilitate the tilting of the vertical rod 310, so that the tooth block 321 cancels the meshing with the rack 420.

[0042] The bottom end of the vertical pole 310 is fixedly mounted with a sector block 320, and the bottom end of the sector block 320 is fixedly mounted with a plurality of tooth blocks 321 for controlling the left and right movement of the adjusting tube 002. The top end of the vertical pole 310 is fixedly mounted with a fixing block 330, and the top middle part of the fixing block 330 is provided with a regular hexagonal slot 331 for conveniently controlling the rotation of the vertical pole 310. The vertical pole 310 can be rotated by inserting an Allen wrench into the hole of the regular hexagonal slot 331, so that the sector block 320 rotates with the limiting shaft 214 as the axis, so as to cooperate with the rack 420 to drive the tube body 400 to move, so as to facilitate the horizontal rail 10 to move out of the hole of the limiting hole 430, so as to replace the damaged horizontal rail 10.

[0043] The regulating tube 002 for limiting the horizontal rail 10 includes a tube body 400, and a plurality of limiting slide bars 410 for cooperating with the limiting groove 121 for limiting the tube body 400 are fixedly installed on the outer wall of the tube body 400, and a rack 420 for cooperating with the tooth block 321 to control the left and right movement of the tube body 400 is fixedly installed on the middle upper end of the tube body 400.

[0044] When the crossbar 10 is damaged and needs to be replaced, the hexagonal wrench is inserted into the cavity of the hexagonal slot 331, and the vertical rod 310 is rotated, so that the fixing block 330 is offset in the direction of the damage of the crossbar 10, and the tooth block 321 meshing with the rack 420 drives the tube body 400 away from the damaged crossbar 10, so that the crossbar 10 moves out of the cavity of the limiting hole 430, thereby facilitating the disassembly and replacement of the crossbar 10, and the vertical rod 310 needs to be rotated multiple times. When the horizontal rail 10 can be disassembled, when the upper end of the vertical rod 310 is rotated to one side of the operating port 213, the fixed block 330 is moved to the side so that the fan-shaped block 320 is away from the rack 420, and then the fixed block 330 is offset toward the direction of the intact horizontal rail 10, and the fixed block 330 is straightened so that the tooth block 321 and the rack 420 are engaged, and the vertical rod 310 continues to be rotated to control the horizontal rail 10 to move out of the cavity of the limiting hole 430.

[0045] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
