Description

Technical Field

[0001] The utility model relates to the field of guardrails, in particular to a bridge anti-collision guardrail. Background Art

[0002] Traditional bridge guardrails are mostly made of materials such as concrete and metal. Although they play a protective role to a certain extent, there are many limitations. For example, although concrete guardrails are strong and durable, their installation and maintenance costs are relatively high, and their visual effects are poor. Secondly, the fixing methods of some existing guardrails are relatively single, relying only on bolts or welding, etc., resulting in easy loosening or falling off when subjected to strong impacts, and unable to effectively protect the safety of bridges and passing vehicles and pedestrians. Content of the Utility Model

[0003] The purpose of the utility model is to provide a bridge anti-collision guardrail, and solve the following technical problems: how to achieve rapid installation while ensuring the stability after installation.

[0004] To solve the problems existing in the prior art, the technical scheme adopted by the utility model is as follows:

[0005] A bridge anti-collision guardrail includes a column. An embedding groove is opened on one side of the top of the column. The opening of the embedding groove is used for the pushing-in installation of a cross bar. A C-shaped plate is rotatably connected in the embedding groove. One side of the C-shaped plate is attached to the inner wall of the embedding groove, and the other side of the C-shaped plate is curved downward in an arc shape, and the lower edge finally remains flush with the side surface of the column;

[0006] A cross bar is embedded in the C-shaped plate.

[0007] Preferably, a sleeve is slidably connected to the outside of the top of the column.

[0008] Preferably, a sliding hole is opened on the surface of the sleeve, and a sliding block is fixedly connected to one side of the top of the column. The sliding block is slidably connected to the sliding hole.

[0009] Preferably, a threaded hole is provided on one side of the bottom of the C-shaped plate, and the threaded hole is arranged opposite to the sliding hole.

[0010] Preferably, two columns are symmetrically arranged, and a grid is fixedly connected between the two columns.

[0011] Preferably, lugs are symmetrically and fixedly connected to both sides of the column, connection pieces are fixedly connected to the four corners of the grid, and the connection pieces and the corresponding lugs are fixedly connected by bolts.

[0012] Preferably, the C-shaped plate and the inner wall of the embedding groove are elastically connected by a torsion spring.

[0013] Preferably, the inner diameter of the embedding groove is the same as the diameter of the cross bar.

[0014] Compared with the related technologies, the utility model has the following beneficial effects:

[0015] Through the ingenious design of the C-shaped plate and the embedding groove, the cross bar can be easily pushed in and automatically locked without additional fasteners, greatly simplifying the installation process. At the same time, this design also makes the disassembly of the cross bar convenient and fast, facilitating maintenance and replacement. The C-shaped plate automatically flips during the pushing process of the cross bar and tightly sleeves outside the cross bar, jointly forming a stable locking mechanism with the embedding groove, effectively preventing the cross bar from loosening or falling off due to external forces. In addition, the sliding design of the housing further enhances the fixing effect of the cross bar, ensuring the stability of the entire guardrail structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose, technical solutions and advantages of the utility model more clear and understandable, the following further details the utility model in conjunction with the drawings and embodiments.

[0022] The bridge anti-collision guardrail has a column 1 and a cross bar 2;

[0023] As Figures 1 to 4 shown, an embedding groove 11 is opened on one side of the top end of the column 1. The opening of the embedding groove 11 is used for the pushing and installation of the cross bar 2. A C-shaped plate 3 is rotatably connected in the embedding groove 11. One side of the C-shaped plate 3 is attached to the inner wall of the embedding groove 11. The other side of the C-shaped plate 3 is curved downward in an arc, and the lower edge finally remains flush with the side surface of the column 1. The cross bar 2 is embedded in the C-shaped plate 3.

[0024] When it is necessary to install the cross bar 2 between the columns 1, the cross bar 2 is pushed in from the opening of the embedding groove 11. In the initial state, the opening of the C-shaped plate 3 is in the same direction as the opening of the embedding groove 11. At this time, the cross bar 2 can be smoothly pushed into the C-shaped plate 3 in the embedding groove 11. As the cross bar 2 is pushed in, its own weight will cause the cross bar 2 to slide down in the embedding groove 11. This sliding process will drive the C-shaped plate 3 to flip downward, and finally the C-shaped plate 3 will tightly fit around the outside of the cross bar 2 with the opening facing downward. At this time, the C-shaped plate 3 and the embedding groove 11 are tightly matched to jointly and firmly position the cross bar 2 at the specified position, so as to assemble the cross bar 2 between the two columns 1.

[0025] As Figures 1 to 4 shown, a housing 4 is slidably connected to the outer side of the top end of the column 1.

[0026] As Figures 1 to 4 shown, a sliding hole 41 is formed on the surface of the housing 4, and a slider 12 is fixedly connected to one side of the top end of the column 1. The slider 12 is slidably connected to the sliding hole 41.

[0027] Through the cooperation of the slider 12 and the sliding hole 41 on the surface of the housing 4, the sliding of the housing 4 on the column 1 is realized. When the housing 4 slides down, the opening of the embedding groove 11 of the column 1 can be closed, thereby blocking the C-shaped plate 3 and preventing the C-shaped plate 3 from flipping upward, making the cross bar 2 more firmly assembled.

[0028] As Figures 1 to 4 shown, a threaded hole 31 is provided on one side of the bottom of the C-shaped plate 3, and the threaded hole 31 is arranged opposite to the sliding hole 41. The C-shaped plate 3 is further strengthened by inserting a threaded rod through the sliding hole 41 and being threadedly connected to the threaded hole 31.

[0029] As Figures 1 to 4 shown, two columns 1 are symmetrically arranged, and a grid 5 is fixedly connected between the two columns 1. The grid 5 is connected to enhance the stability and protection effect of the overall structure.

[0030] As Figures 1 to 4 shown, lugs 13 are symmetrically and fixedly connected to both sides of the column 1, and connecting pieces 51 are fixedly connected to the four corners of the grid 5. The connecting pieces 51 and the corresponding lugs 13 are fixedly connected by bolts 6. The connecting pieces 51 are fixedly connected to the lugs 13 on both sides of the column 1 by bolts 6, realizing the stable connection between the grid 5 and the column 1, which is more convenient during assembly.

[0031] As Figures 1 to 4 shown, the C-shaped plate 3 and the inner wall of the embedding groove 11 are elastically connected by a torsion spring 7. The C-shaped plate 3 has a certain ability of automatic reset, so that the opening of the C-shaped plate 3 can be kept in the same direction as the opening of the embedding groove 11 in the initial state, so as to facilitate the pushing and assembling of the cross bar 2.

[0032] As Figures 1 to 4As shown, the inner diameter of the embedding groove 11 is the same as the diameter of the cross bar 2, making the cross bar 2 more stable after being assembled into the embedding groove 11.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
