Description

Technical Field

[0001] This utility model relates to the technical field of highway bridge protection equipment, specifically to an anti-collision protection device for road and bridge piers. Background Technology

[0002] As transportation becomes more developed, there are more and more overpasses and interchanges on roads, resulting in more exposed bridge piers along the roads. Therefore, in order to cope with traffic accidents involving heavy trucks, assembled concrete protective piers of a certain height are usually installed on the outside of the bridge piers.

[0003] According to the publication (announcement) number: CN113174888B, the publication (announcement) date: 2023-04-14, a protective bridge pier with high impact resistance for highway bridges is disclosed, including an outer protective plate located on the outside of the bridge pier.

[0004] In the prior art, including the aforementioned patent, since cement protective barriers can only be set at a predetermined position on the outside of the bridge pier, and then several fixed steel bars are buried in the ground, when the impact force is large, the inertia of the cement protective barrier will cause it to detach from the top of the steel bars and crash into the bridge pier along with the impact, still causing damage to the bridge pier. In fact, the cement protective barrier may even "uproot" some steel bars that are not inserted deep enough but are stably connected, causing secondary damage to heavy trucks involved in traffic accidents. Moreover, the road construction team also has a heavy burden when transporting cement protective barriers. Utility Model Content

[0005] The purpose of this invention is to provide an anti-collision protection device for road and bridge piers, aiming to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A collision protection device for a road and bridge pier includes a bridge pier, wherein an assembled protective cover is provided on the outer side of the bridge pier, and multiple connecting covers are fixedly installed on the inner side wall of the protective cover.

[0008] It also includes a column with a pointed cone at the end and a sliding groove on the side, and an inclined block that slides with the sliding groove is fixedly installed on the inner side wall of the connecting cover.

[0009] Preferably, the end of the protective cover is fixedly installed with multiple feet.

[0010] Preferably, elastic members arranged at equal intervals are fixedly installed between the column and the protective cover.

[0011] Preferably, the connecting cover has a notch, and a support column that cooperates with the column and forms a triangular support is slidably disposed in the notch.

[0012] Preferably, the lower end of the support column is provided with a pointed cone.

[0013] Preferably, the column is also provided with a slot that fits into the upper end of the support.

[0014] Preferably, the upper end of the support column can slide and switch with the equally spaced slots during the active phase.

[0015] Preferably, the elastic element is a spring.

[0016] Preferably, the column is a columnar steel plate.

[0017] Preferably, the connecting cover is a U-shaped steel plate cover.

[0018] In the above technical solution, the anti-collision protection device for road and bridge piers provided by this utility model has the following beneficial effects: the impact force is dispersed by the sliding of multiple inclined blocks and grooves, avoiding the situation where the impact force is too concentrated and the protective cover plate is severely deformed locally or even detached and unable to buffer, thus ensuring that the protective cover plate will not be hit by the bridge pier. At the same time, the pushing force of the inclined blocks causes the column to continue to penetrate into the soil along the cone, further improving the support stability of the column, making it less likely for the protective cover plate to approach the bridge pier after being hit, thereby making the bridge pier more protected and safer.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-4 As shown, a collision protection device for a road and bridge pier includes a pier 1, an assembled protective cover 2 on the outside of the pier 1, and multiple connecting covers 4 fixedly installed on the inner side wall of the protective cover 2.

[0028] It also includes a column 3 with a pointed cone at the end and a sliding groove 32 on the side, and an inclined block 41 that slides and engages with the sliding groove 32 is fixedly installed on the inner wall of the connecting cover 4.

[0029] Specifically, the L-shaped protective cover 2, after assembly, forms a square frame. The connecting positions of the protective cover 2 have cylindrical protrusions and cylindrical grooves, so that the protective cover 2 can be inserted into each other during on-site assembly, making installation simpler. The protective cover 2 is made of steel plate, and after assembly, a waterproof warning tape (the material is existing technology and will not be described in detail here) is attached to the outer wall of the protective cover 2. At the same time, the warning tape also covers the upper port of the square frame.

[0030] Furthermore, the slides 32 are equidistantly and symmetrically arranged on both sides of the column 3, and the end of the inclined block 41 is provided with an inclined surface, which does not contact the port of the slide 32 in the default state.

[0031] When the protective cover 2 is impacted, the force is transmitted to the connecting cover 4, causing multiple inclined blocks 41 to move towards the pier 1. During this process, the inclined blocks slide against the ports of the sliding grooves 32, and the multiple sliding grooves 32 are used to disperse the impact force, avoiding excessive concentration of impact force that could cause severe local deformation of the protective cover 2 or even detachment, thus preventing it from being impacted into the pier 1. At the same time, the pushing force of the inclined blocks 41 causes the column 3 to continue to penetrate deeper into the soil along the cone, further improving the support stability of the column 3. This makes it even more difficult for the protective cover 2 to approach the pier 1 after an impact, thereby strengthening the protection function of the pier 1 and increasing its safety.

[0032] As a further embodiment of this utility model, a plurality of feet 21 are fixedly installed at the end of the protective cover plate 2.

[0033] Specifically, holes are provided on the base 21 for inserting and fixing shorter steel bars (20-25 cm in length).

[0034] Multiple feet 21 are used to stabilize the protective cover plate 2 on the ground, and the reinforcing bars can be easily detached from the feet 21 so that the protective cover plate 2 can move when it is under pressure. The shorter reinforcing bars can also reduce secondary damage caused when the soil is pulled out.

[0035] As another embodiment further provided in this utility model, elastic members 31 arranged at equal intervals are fixedly installed between the column 3 and the protective cover plate 2.

[0036] The protective cover 2, which moves under impact, applies pressure to the elastic element 31 to buffer the impact force, thereby dispersing the impact force more effectively.

[0037] As another embodiment further provided by this utility model, the connecting cover 4 is provided with a notch 42, and a support column 5 that cooperates with the column 3 and forms a triangular support is slidably disposed on the notch 42.

[0038] The support column 5 forms a stable triangular structure on the column 3, which is used to enhance the stability of the column 3 when it is inserted into the soil. When the upper part of the support column 5 slides in the notch 42, it can also provide support and buffer space for the column 3 when it tilts.

[0039] As another embodiment provided in this utility model, the lower end of the support column 5 is provided with a pointed cone.

[0040] By inserting the lower end of the support column 5 into the soil, the tilted support column 3 can still transfer force to the support column 5, allowing the support column 5 to continue to penetrate deeper into the soil and further improve the buffering capacity.

[0041] As another embodiment provided in this utility model, the column 3 is also provided with a slot 33 that fits into the upper end of the support column 5.

[0042] The triangular slot 33 provides a stable support connection for the support column 5 and also facilitates the transfer of force to the support column 5.

[0043] As another embodiment provided by this utility model, the upper end of the movable lower support 5 slides and switches with the equally spaced slots 33.

[0044] The resistance generated by the support column 5 penetrating deep into the soil restricts the movement of the upper end of the support column 5, and the actively tilted column 3 can slide the upper end of the support column 5 out of the slot 33. When the tilted state is maintained for a short time, the upper end of the support column 5 slides upward in a series of slots 33 to increase the resistance of the support column 5 to the tilt of the column 3, so that the column 3 can maintain better vertical stability.

[0045] As another embodiment further provided in this utility model, the elastic element 31 is specifically a spring.

[0046] The spring makes the elastic element 31 deform more significantly, resulting in better cushioning and less impact on the stable erection of the column 3.

[0047] As another embodiment further provided in this utility model, the column 3 is specifically a columnar steel plate.

[0048] The use of steel plates makes the column 3 less prone to deformation under stress, which means that the column 3 has a stable and deep insertion effect into the soil, and its support and protection functions are stronger, making it less likely to cause impact damage to the bridge pier 1.

[0049] As another embodiment provided in this utility model, the connecting cover 4 is specifically a U-shaped steel plate cover.

[0050] The opening of the connecting cover 4 faces the inner wall of the protective cover plate 2, so that the protective cover plate 2 can quickly move towards the column 3 when subjected to force, so as to buffer and penetrate into the soil. At the same time, the steel material can reduce the squeezing damage to the connecting cover 4, so that the connecting cover 4 can be reused.

[0051] Working principle: When the protective cover plate 2 is impacted, the force is transmitted to the connecting cover 4, causing multiple inclined blocks 41 to move towards the pier 1. During the process, the inclined blocks slide against the port of the sliding groove 32, and the multiple sliding grooves 32 are used to disperse the impact force, avoiding the impact force from being too concentrated and causing severe local deformation of the protective cover plate 2, or even detachment and failure to buffer. This ensures that the protective cover plate 2 will not be hit by the pier 1. At the same time, the pushing force of the inclined blocks 41 causes the column 3 to continue to penetrate into the soil along the cone, further improving the support stability of the column 3. This makes it less likely for the protective cover plate 2 to get close to the pier 1 after being impacted, thus making the pier 1 more protected.

[0052] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
