[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 3 This utility model provides a technical solution:

[0019] A quick-installation device for a highway roadside corrugated beam guardrail includes a post 1, a guardrail 2, and a fixing assembly for connecting the post 1 and the guardrail. The post 1 has a mounting base 3 at its bottom and a detachable sealing cap 4 at its top. The guardrail includes a first corrugated beam 5 and a second corrugated beam 6. The overlapping connection between the first corrugated beam 5 and the second corrugated beam 6 is fixed by multiple first bolts 7. The fixing assembly includes a connecting frame 8 and two connecting plates 9 slidably installed at one end of the connecting frame 8. The other end of the connecting frame 8 has a U-shaped groove 11 adapted to the post 1, and both sides are fixed to the post 1 by multiple second bolts 10. Connecting rods 12 are fixedly installed on both connecting plates 9, and are fixed to the first corrugated beam 5 and the second corrugated beam 6 by multiple third bolts 13.

[0020] The mounting base 3 has multiple first mounting holes and multiple reinforcing plates 14 are provided between it and the column 1. Multiple second mounting holes are provided on the outside of the column 1 to further improve the overall support strength.

[0021] The connecting plate 9 has the same cross-sectional shape as the first wave beam 5 and the second wave beam 6.

[0022] A rod 15 is fixedly installed in the middle of the U-shaped groove 11. A slot 17 adapted to the rod 15 is symmetrically opened on the outside of the column 1. One end of the rod 15 passes through the slot 17 and is screwed on with a fixing ring 16. The fixing ring 16 is in contact with the surface of the column 1.

[0023] During operation, the first corrugated beam 5 and the second corrugated beam 6 are fixed together by multiple first bolts 7 to form the guardrail 2. Then, they are connected to the column 1 by fixing components, and the first corrugated beam 5 and the second corrugated beam 6 are tightly fitted with the two connecting plates 9 and fixed by multiple third bolts 13. This increases the contact area during installation and enhances the firmness and stability of the installation. The U-shaped groove 11 at one end of the connecting frame 8 is fitted onto the outside of the column 1. The installation height on the column 1 can be adjusted to a suitable position according to the actual installation requirements. Finally, the guardrail 2 is fixed by multiple third bolts 13. Bolt 10 secures the connecting frame 8 and the post 1. Simultaneously, the insert rod 15 in the middle of the U-shaped groove 11 is inserted into the corresponding slot 17 and can move up and down within the slot 17 with the connecting frame 8 until it reaches the appropriate position. Tightening the fixing ring 16 makes it contact the surface of the post 1, and the frictional resistance of the contact serves as a limiting and fixing function, thereby improving the strength of the connection, enhancing the load-bearing strength and protective effect during impact, improving the safety of the corrugated beam guardrail, and the entire corrugated beam guardrail is easy to disassemble and quickly install, and can adapt to corrugated beams of different heights.

[0024] The connecting frame 8 has a cavity at one end, and a bidirectional screw 19 is rotatably installed in the cavity. Guide rods 18 are fixedly installed on both sides of the bidirectional screw 19. Movable blocks 20 are installed at both ends of the bidirectional screw 19, and a knob is installed at one end of the screw 19, which extends to the outside of the connecting frame 8. The two ends of the movable blocks 20 are respectively inserted through the guide rods 18. Sliding grooves 21 are symmetrically opened on the outside of the cavity. The connecting rod 12 is movably installed in the sliding groove 21, and one end extends into the cavity and is fixedly connected to the movable block 20.

[0025] When fixed, the position of the two connecting plates 9 can be adjusted according to the position of the overlapping connection between the first wave beam 5 and the second wave beam 6. Specifically, the two-way screw 19 can be rotated by holding the knob, which can drive the moving blocks 20 at both ends to move simultaneously, thereby driving the two connecting rods 12 to move in the sliding groove, thus realizing the adjustment of the position of the two connecting plates 9 and improving the flexibility of the installation operation.

[0026] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
