Description

Technical Field

[0001] This utility model relates to the field of bridge concrete guardrail technology, and in particular to a bridge concrete guardrail anti-collision buffer device. Background Technology

[0002] Bridge concrete railings refer to railings made primarily of cement concrete and installed on bridges; they are also known as bridge cement railings.

[0003] Collision buffer devices can absorb and disperse the energy of a vehicle impact, reducing damage to bridge concrete railings and vehicles, while protecting the safety of passengers inside the vehicle.

[0004] However, most existing bridge concrete guardrails are not equipped with crash buffer devices, making their protective capabilities relatively weak when faced with an out-of-control vehicle impact. Because concrete itself has a certain degree of rigidity and brittleness, the guardrails may break or fracture under strong impact, failing to effectively absorb and disperse impact energy, thus increasing the risk of damage to vehicles and passengers. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a bridge concrete guardrail anti-collision buffer device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A bridge concrete guardrail anti-collision buffer device includes a concrete guardrail body. Multiple anti-collision buffer components are evenly arranged on one side of the concrete guardrail body, and the anti-collision buffer components and the concrete guardrail body are connected and fixed by multiple high-strength bolts. The anti-collision buffer component includes a first mounting plate, a fixed shaft is fixedly installed on the top of the first mounting plate, an anti-collision buffer roller assembly is sleeved on the outer wall of the fixed shaft, and a second mounting plate is sleeved on the upper part of the outer wall of the fixed shaft. A limiting ring is sleeved on the top of the second mounting plate outside the fixed shaft.

[0008] The anti-collision buffer roller assembly includes a roller body, an annular cavity is formed inside the roller body, a reinforcing steel reinforcement assembly is placed inside the annular cavity, and a sponge ring is fixedly sleeved on the outer wall of the roller body.

[0009] Furthermore, in a preferred configuration, the reinforcing steel assembly includes several vertical reinforcing ribs and several reinforcing rib rings, with the several vertical reinforcing ribs arranged in a ring at equal intervals within the annular cavity, and several reinforcing rib rings installed at equal intervals between the several vertical reinforcing ribs.

[0010] Furthermore, in a preferred configuration, reflective rings and anti-collision rubber rings are installed at equal intervals on the outer wall of the sponge ring, and the width of the reflective rings is smaller than the width of the anti-collision rubber rings.

[0011] In addition, a preferred structure is that multiple T-shaped fixing blocks are symmetrically installed at equal distances at the top and bottom of the limiting ring, and a feed through hole is opened at the top of the second mounting plate at the T-shaped fixing block, and a movable cavity is opened inside the second mounting plate at the T-shaped fixing block.

[0012] In addition, a preferred structure is that a fixing plate is vertically fixed on one side of both the first mounting plate and the second mounting plate, and multiple mounting through holes are opened at equal intervals in the fixing plate.

[0013] In addition, a preferred structure is that an extension rod is vertically fixedly installed at the bottom of the first mounting plate at the fixed shaft, and a counterweight base is fixedly installed on the other side of the extension rod.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this utility model, multiple anti-collision buffer components are equidistantly arranged on one side of the concrete guardrail body. When a vehicle accidentally hits the guardrail, the rollers can convert the huge impact force into rotational kinetic energy, thereby effectively dispersing and mitigating the impact force, reducing the degree of vehicle damage and the risk of injury to occupants. Moreover, the anti-collision buffer components are detachable, and when a roller malfunctions or is damaged, it can be removed individually for repair or replacement. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3A bridge concrete guardrail anti-collision buffer device includes a concrete guardrail body 1. Multiple anti-collision buffer components 2 are evenly arranged on one side of the concrete guardrail body 1, and the anti-collision buffer components 2 and the concrete guardrail body 1 are connected and fixed by multiple high-strength bolts. The anti-collision buffer component 2 includes a first mounting plate 21, a fixed shaft 23 is fixedly installed on the top of the first mounting plate 21, an anti-collision buffer roller assembly 25 is sleeved on the outer wall of the fixed shaft 23, and a second mounting plate 22 is sleeved on the upper part of the outer wall of the fixed shaft 23. A limiting ring 24 is sleeved on the top of the second mounting plate 22 outside the fixed shaft 23. It is worth noting that the specific structure and working principle of the concrete guardrail body 1 are existing technologies that are currently disclosed in the market and are not the main technical problems to be solved by this utility model. Therefore, this utility model will not elaborate further.

[0022] The anti-collision buffer roller assembly 25 includes a roller body 251, an annular cavity is provided inside the roller body 251, a reinforcing steel rod assembly 252 is placed inside the annular cavity, and a sponge ring 253 is fixedly sleeved on the outer wall of the roller body 251. It is worth noting that the roller body 251 is made of polyurethane material.

[0023] Furthermore, the reinforcing steel assembly 252 includes several vertical reinforcing bars and several reinforcing bar rings, with the several vertical reinforcing bars arranged in a ring at equal intervals within the annular cavity, and several reinforcing bar rings installed at equal intervals between the several vertical reinforcing bars.

[0024] Meanwhile, reflector rings 254 and anti-collision rubber rings 255 are installed at equal intervals on the outer wall of the sponge ring 253, and the width of the reflector ring 254 is smaller than the width of the anti-collision rubber ring 255.

[0025] Meanwhile, multiple T-shaped fixing blocks are symmetrically installed at equal distances on the top and bottom of the limiting ring 24, and a feed through hole is opened at the top of the second mounting plate 22 at the T-shaped fixing block, and a movable cavity is opened inside the second mounting plate 22 at the T-shaped fixing block.

[0026] Furthermore, a fixing plate is vertically fixed on one side of both the first mounting plate 21 and the second mounting plate 22, and multiple mounting through holes are equally spaced inside the fixing plate.

[0027] Furthermore, an extension rod 26 is vertically fixedly installed at the bottom of the first mounting plate 21 at the fixed shaft 23, and a counterweight base 261 is fixedly installed on the other side of the extension rod 26.

[0028] In this embodiment, multiple anti-collision buffer components 2 are equidistantly arranged on one side of the concrete guardrail body 1. When a vehicle accidentally hits the guardrail, the roller body 1 can convert the huge impact force into rotational kinetic energy, thereby effectively dispersing and mitigating the impact force, reducing the degree of vehicle damage and the risk of injury to occupants. At the same time, the reflective ring 254 provides clear visual warnings to drivers both day and night, improving road visibility. By setting reinforcing steel reinforcement components 252 inside the roller body 1, the structural strength of the roller body 1 can be improved, and its impact resistance can be enhanced. Furthermore, the anti-collision buffer components 2 are detachable, so when a roller malfunctions or is damaged, it can be removed individually for repair or replacement.

When a vehicle accidentally hits the guardrail, the rollers can convert the huge impact force into rotational kinetic energy, thereby effectively dispersing and mitigating the impact force, reducing the degree of vehicle damage and the risk of injury to occupants. Moreover, the anti-collision buffer components 2 are detachable. When a roller malfunctions or is damaged, it can be removed individually for repair or replacement.
