[0001] The utility model belongs to the technical field of bridge protection, and particularly relates to a highway bridge anti-collision device. Background Art
[0002] With the development of China's economy and the continuous improvement of the living standards of the people, the construction of road bridges is also developing rapidly. However, the resulting road traffic safety accidents have become increasingly prominent. Many of the accidents are caused by the lack of good road anti-collision devices, resulting in casualties. At present, anti-collision devices are installed on both sides of general roads and bridges. The anti-collision device refers to the guardrail installed on the bridge, and its purpose is to prevent out-of-control vehicles from going out of the bridge. It has the functions of preventing vehicles from breaking through, passing under, or climbing over the bridge and beautifying the bridge structure.
[0003] At present, the anti-collision devices on the market only form a simple guardrail by support columns and cross plates to protect the cars. As a result, the existing anti-collision devices have poor buffering ability when being impacted, so that the vehicles still have a great impact force during the impact and cannot play a good protective role.

At this time, the buffer cavities play a primary buffer effect, and the elasticity of the elastic structure plays a secondary buffer effect, so that when the cross plate is impacted, a double buffer protection effect is achieved, the buffering ability is improved, and a good protective effect is achieved on the vehicle during the impact.
[0007] Further, the elastic structure includes a buffer box, a plurality of deformation grooves formed on both sides of the buffer box, and a first elastic member disposed inside the buffer box.

[0008] Further, on one side of the two cross plates close to each other, card slots are respectively formed. A clamping block is inserted into the card slots. The clamping block is connected to the elastic structure, and the cross section of the clamping block is arranged in a T shape.
[0009] Further, the elastic extrusion structure includes two extrusion plates and a second elastic member disposed between the two extrusion plates. The bottoms of the two extrusion plates are respectively slidably connected to the bottom of the limiting groove.

For example, it may be a fixed connection, a detachable connection, or an integral body; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.
[0024] As Figure 1 and Figure 2 shown, in the first embodiment of the present utility model, a highway bridge anti-collision device is provided, including: a plurality of columns 10 arranged in a row and a plurality of cross beam assemblies 20. The cross beam assemblies 20 are arranged between two adjacent columns 10. The side wall of the column 10 is connected to the end of the cross beam assembly 20 through a connection assembly 30. The cross beam assembly 20 includes two cross plates 21 arranged at intervals and an elastic structure 22 detachably arranged between the two cross plates 21, so as to form a plurality of buffer cavities 23 between the two cross plates 21. The connection assembly 30 includes a limiting groove 31 opened on one side of the column 10, an elastic extrusion structure 32 arranged in the limiting groove 31, and two limiting members 33 arranged in the limiting groove 31 and on both sides of the elastic extrusion structure 32 respectively. The limiting member 33 is connected to one end of the cross plate 21. The elastic extrusion member is used to limit the two limiting members 33 in the limiting groove 31 and form a buffer for the two limiting members 33.
[0025] It should be noted that by arranging the elastic structure 22 between the two cross plates 21, a plurality of buffer cavities 23 are formed between the two cross plates 21, and the two cross plates 21 are limited together to improve the stability between them. At this time, a primary buffer effect is achieved through the buffer cavities 23, and a secondary buffer effect is achieved through the elasticity of the elastic structure 22, so that when the cross plate 21 is impacted, a double buffer protection effect is achieved, the buffer capacity is improved, and a good protection effect is achieved when the vehicle is impacted;
[0026] In addition, through the detachable arrangement of the elastic structure 22, the elastic structure 22 and the cross plate 21 are detachable. In addition, by making the elastic extrusion structure 32 not extrude the limiting member 33, the limitation on the limiting member 33 is lost, and the limiting member 33 can be detached from the limiting groove 31, so that the cross plate 21 and the column 10 can be detached. It can be seen that when a certain component in the cross beam assembly 20 is impacted and bent and damaged, the changed component can be replaced, improving the practicability of the highway bridge anti-collision device of the present application.
[0027] As Figure 3As shown, the elastic structure 22 includes a buffer box 221, a plurality of deformation grooves 222 opened on both sides of the buffer box 221, and a first elastic member 223 arranged inside the buffer box 221, the two ends of the first elastic member 223 are respectively connected to the two inner walls of the buffer box 221, the deformation grooves 222 are used to enable the buffer box 221 to undergo wrinkle deformation, and the first elastic member 223 is used to buffer the wrinkle deformation of the buffer box 221. It is worth mentioning that a plurality of deformation grooves 222 are arranged on both sides of the buffer box 221 so that the buffer box 221 can be wrinkled and deformed after one end of the buffer box 221 is hit. When the cross plate 21 is hit by the outside, the deformation grooves 222 opened on both sides of the buffer box 221 can make the buffer box 221 wrinkle and deform under the severe impact force, thereby buffering the impact force. In the process of deformation of the buffer box 221, the elastic effect of the first elastic member 223 can buffer the impact force generated by the deformation of the buffer box 221, thereby avoiding the phenomenon of the buffer box 221 being broken due to excessive impact force.
[0028] Furthermore, a card slot 211 is respectively provided on one side of the two horizontal plates 21 close to each other, and a card block 212 is inserted into the card slot 211. The card block 212 is connected to the elastic structure 22, and the cross section of the card block 212 is set in a T shape. The card block 212 is inserted into the card slot 211 to facilitate the installation and removal of the card block 212, thereby facilitating the installation and removal of the elastic structure 22.
[0029] like Figure 4As shown, the elastic extrusion structure 32 includes two extrusion plates 321 and a second elastic member 322 disposed between the two extrusion plates 321. The bottom portions of the two extrusion plates 321 are respectively slidably connected to the bottom of the limiting groove 31. In specific implementation, when two cross plates 21 need to be installed, first move the elastic extrusion structure 32 towards one end of the limiting groove 31 to make the size of the other end of the limiting groove 31 larger. When the size of the other end is large enough, place the limiting member 33 of one cross plate 21 into the other end of the limiting groove 31 (i.e., one side of the elastic extrusion structure 32). Then, squeeze one extrusion plate 321 of the elastic extrusion structure 32 towards the direction close to the other extrusion plate 321 (i.e., move one extrusion plate 321 towards the limiting member 33 installed in the limiting groove 31 at this time), so that one extrusion plate 321 squeezes the second elastic member 322, thereby making the size of one end of the limiting groove 31 also larger. When the size of one end is large enough, place the limiting member 33 of the other cross plate 21 into one end of the limiting groove 31 (i.e., the other side of the elastic extrusion structure 32). Then, release the extrusion on the second elastic member 322, so that the restored elastic force of the second elastic member 322 squeezes the two extrusion plates 321 towards both sides at the same time. Thus, the two extrusion plates 321 respectively squeeze the two limiting members 33, so that the limiting members 33 are limited in the limiting groove 31, thereby making the cross plate 21 limited on the column 10. At the same time, through the setting of the second elastic member 322, buffering of the limiting member 33 can also be achieved, thereby buffering the cross plate 21. When the cross plate 21 needs to be disassembled, squeeze the extrusion plate 321 again to make the distance between the two extrusion plates 321 smaller, release the extrusion limit on the limiting member 33, and the limiting member 33 can be disassembled, so that the cross plate 21 can be disassembled, facilitating the disassembly and installation of the cross plate 21 and the replacement of the cross plate 21.
[0030] In this embodiment, both the first elastic member 223 and the second elastic member 322 are springs 342.
[0031] Further, in order to more stably limit the limiting member 33 within the limiting groove 31, limiting blocks 35 are provided on both sides of the limiting groove 31 through a third elastic member 34. The limiting blocks 35 are adapted to the limiting member 33 so that the limiting member 33 is limited within the limiting groove 31. Further still, the third elastic member 34 includes a receiving groove 341 opened on one side of the limiting groove 31 and a spring 342 disposed within the receiving groove 341. The spring 342 is connected to the limiting block 35, and the receiving groove 341 is adapted to the limiting block 35. Specifically, during installation, first, the limiting block 35 is squeezed so that the limiting block 35 squeezes the spring 342 into the receiving groove 341. Then, the limiting member 33 is inserted into the limiting groove 31. After being completely inserted into the limiting groove 31, at this time, the restoring elastic force of the spring 342 that has lost the extrusion causes the limiting block 35 to protrude out of the receiving groove 341, so that the limiting block 35 stays outside the limiting member 33 to block the limiting member 33 and achieve the limitation of the limiting member 33.
[0032] In this embodiment, at least two of the crossbeam assemblies 20 are provided between every two adjacent columns 10. A plurality of buffer plates 24 are arranged on one side of all the crossbeam assemblies 20 between two adjacent columns 10, and the buffer plates 24 limit all the crossbeam assemblies 20 together. A buffer layer 25 extends from the side of the buffer column away from the crossbeam assembly 20, and the cross-section of the buffer layer 25 is arc-shaped.
[0033] Further, in order to install flower pots, a decorative plate 26 is connected to the other side of all the crossbeam assemblies 20 between two adjacent columns 10, and a plurality of flower pot holes 27 are opened in the decorative plate 26.
[0034] In summary, for the highway bridge anti-collision device in the above embodiments of the present utility model, through the arrangement of the elastic structure 22 between the two cross plates 21, a plurality of buffer cavities 23 are formed between the two cross plates 21, and the two cross plates 21 are limited together to improve the stability between them. At this time, a primary buffering effect is achieved through the buffer cavities 23, and a secondary buffering effect is achieved through the elasticity of the elastic structure 22, so that when the cross plate 21 is impacted, a double buffering protection effect is achieved, improving the buffering ability and providing good protection for the vehicle during impact;
[0035] In addition, through the detachable setting of the elastic structure 22, the elastic structure 22 and the cross plate 21 are detachable. In addition, by making the elastic extrusion structure 32 not extrude the limiting member 33, the limitation on the limiting member 33 is lost, and the limiting member 33 can be detached from the limiting groove 31, so that the cross plate 21 and the column 10 can be disassembled. It can be seen that when a certain component in the cross beam assembly 20 is bent and damaged by impact, the changed component can be replaced, which improves the practicability of the highway bridge anti-collision device of the present application.
[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
