Description

Technical Field

[0001] The utility model relates to the technical field of road guardrails, in particular to a road guardrail protection bracket. Background Art

[0002] As a key component of modern transportation infrastructure, central road guardrails ensure orderly and safe road traffic. They effectively separate the driving lane from the oncoming lane, preventing direct collisions between vehicles. This separation is particularly important on high-speed or high-traffic roads. Guardrails guide traffic flow, preventing vehicles from driving in the wrong direction or accidentally entering the oncoming lane, significantly reducing the risk of traffic accidents. These guardrails typically consist of a main frame made of columns and beams constructed from high-strength steel or aluminum alloy. These materials ensure the guardrail maintains structural stability and integrity even when subjected to external impacts. The guardrail also incorporates anti-collision devices, such as buffer materials or anti-collision plates, which can absorb and disperse the impact force when the vehicle collides, reducing damage; for example, a road guardrail protection bracket disclosed in the authorization announcement number CN213952046U includes a fixed base, the top of the fixed base is fixedly connected to a fixed sleeve, the interior of the fixed sleeve is plugged with a support column, one side of the support column is fixedly connected to two mutually parallel support beams, and a number of mutually parallel support vertical beams are fixedly connected between the two support beams, the support vertical beams are cylindrical, and the appearance of the support vertical beams is cylindrical. The surface is sleeved with a protective mechanism, and a rubber roller is provided. The rubber roller is rotated by external force while providing buffering. Since the contact surface between the rolling inner cylinder and the supporting vertical beam is relatively smooth, rotation occurs between the rolling inner cylinder and the supporting vertical beam, so that the direction of vehicle movement can be guided. However, the above technical solution is still composed of two cross beams and several vertical beams between the two cross beams during use. When the guardrail is subjected to external force (such as vehicle collision), it is still easy to deform or even break, and it cannot effectively prevent out-of-control vehicles from passing through the guardrail, increasing the risk of collision between vehicles and pedestrians in the opposite lane. Utility Model Content

[0003] The purpose of the utility model is to provide a road guardrail protection bracket, the base is bolted to the ground, and a circular double-layer protection frame with steel bars as the basis is installed on the top of the base to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a road guardrail protective bracket, comprising a base and an upward-extending circular double-layer protective frame installed on the outer walls around the base, the circular double-layer protective frame forming a circular cavity structure above the base, two symmetrical first rectangular protrusions and two symmetrical second rectangular protrusions are integrally formed on the left and right outer walls of the base, the tops of the first rectangular protrusions and the second rectangular protrusions are respectively fixed with a main steel column and a secondary steel column, a Z-shaped connecting frame is arranged between the two secondary steel columns in the same Y-axis direction, and the Z-shaped connecting frame is used to connect the main steel column and the secondary steel column.

[0005] Preferably, the circular double-layer protective frame includes arched arms fixed on the outer walls around the base, a circular frame installed on the top of several arched arms, and circular steel bars fixed between several arched arms, and several circular steel bars are arranged at equal intervals from top to bottom.

[0006] Preferably, at least two circular steel bars are provided, and the cross-sectional shape of the circular frame is circular.

[0007] Preferably, the main steel column and the auxiliary steel column are both made of aluminum alloy components.

[0008] Preferably, the Z-shaped connecting frame includes a square bottom plate and a square top plate slidably mounted on the secondary steel column, and a diagonal arm welded and mounted between the top wall of the square bottom plate and the bottom wall of the square top plate. Separate clamps are installed at the corners of the square bottom plate and the square top plate.

[0009] Preferably, the separate holding hoop includes a main holding ring fixed at the corners of the square bottom plate and the square top plate and a secondary holding ring bolted to the main holding ring.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the road guardrail protection bracket is provided with a structure that cooperates with each other, such as a circular double-layer protection frame and a Z-shaped connecting frame, and the base is bolted to the ground, which can provide strong pull-out resistance and lateral resistance, and can ensure that the guardrail bracket is firmly fixed to the ground to prevent it from shifting or tipping over due to external forces such as strong winds and vehicle collisions. The steel bar, as the main material of the circular double-layer protection frame, has high strength and toughness, and can effectively absorb and disperse impact forces from the outside. When a vehicle accidentally hits the guardrail, the steel bar protection frame can slow down the impact speed. Because it has a certain degree of redundancy, even if one layer is severely damaged, the other layer can still maintain a certain protection capability, thereby improving the bearing capacity of the entire bracket structure.

[0017] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-5 The utility model provides an embodiment of a road guardrail protection bracket, comprising a base 1 and an upwardly extending circular double-layer protection frame 2 installed on the outer walls around the base 1, the circular double-layer protection frame 2 forming a circular cavity structure above the base 1, two symmetrical first rectangular protrusions 3 and two symmetrical second rectangular protrusions 4 are integrally formed on the left and right outer walls of the base 1, the tops of the first rectangular protrusions 3 and the second rectangular protrusions 4 are respectively fixed with a main steel column 5 and an auxiliary steel column 6, the main steel column 5 and the auxiliary steel column 6 are both made of aluminum alloy components, a Z-shaped connecting frame 7 is provided between the two auxiliary steel columns 6 in the same Y-axis direction, and the Z-shaped connecting frame 7 is used to connect the main steel column 5 and the auxiliary steel column 6;

[0019] The circular double-layer protective frame 2 includes an arched vertical arm 201 fixed on the outer wall around the base 1, a circular frame 202 installed on the top of several arched vertical arms 201, and a circular steel bar 203 fixed between several arched vertical arms 201. Several circular steel bars 203 are arranged at equal intervals from top to bottom, and there are at least two circular steel bars 203. The cross-sectional shape of the circular frame 202 is circular. The arched structure of the arched vertical arm 201 itself has excellent mechanical properties and can withstand large bending moments and shear forces. By reasonably arranging the arched vertical arm 201 between the circular double-layer protective frame 2 and the circular frame 202, external forces can be effectively transmitted from the arched vertical arm 201 and the circular frame 202 to the base 1 and then dispersed to the ground. The circular frame 202 and the arched vertical arm 201 together constitute a solid frame, thereby increasing the rigidity of the protective frame.

[0020] A plurality of circular steel bars 203 are welded from top to bottom to the plurality of arched arms 201, forming a cage-like structure inside the plurality of arched arms 201. This structure prevents the arched arms 201 from bending or breaking when subjected to external forces. Even if the outer arched arms 201 are damaged, the circular steel bars 203 located inside can still provide effective protection.

[0021] The Z-shaped connecting frame 7 includes a square bottom plate 701 and a square top plate 702 which are slidably mounted on the secondary steel column 6, and an inclined pull arm 704 which is welded between the top wall of the square bottom plate 701 and the bottom wall of the square top plate 702. Separate clamps 703 are installed at the corners of the square bottom plate 701 and the square top plate 702. When the head and tail ends of two adjacent bases 1 are facing each other, the square bottom plate 701 and the square top plate 702 are mounted on the secondary steel column 6 and the main steel column 5 through the separate clamps 703, so that the main steel column 5 and the secondary steel column 6 can be connected, thereby helping the protective bracket to be assembled;

[0022] The detachable clamp 703 includes a main clamp 7031 fixed at the corners of the square bottom plate 701 and the square top plate 702, and a secondary clamp 7032 bolted to the main clamp 7031. The main clamp 7031 and the secondary clamp 7032 are connected by bolts, which allows the support structure formed by the inclined arm 704, the square bottom plate 701, and the square top plate 702 to be removed from between two adjacent guardrails. If any problems are found in the guardrails, they can be quickly repaired or replaced.

[0023] When the embodiment of the present application is in use, the staff first takes out several road guardrail protection brackets so that the head and tail ends of the two adjacent bases 1 are aligned. At this time, the main steel columns 5 and the auxiliary steel columns 6 between the head and tail ends of the two bases 1 are in a relative state. The staff then uses the Z-shaped connecting frame 7 to connect the main steel columns 5 and the auxiliary steel columns 6. At this time, the main steel columns 5, the auxiliary steel columns 6, and the Z-shaped connecting frame 7 form four connection points between the head and tail ends of the two bases 1, so that the two adjacent road guardrail protection brackets are assembled and connected. The staff can assemble the protection brackets in sequence in the extension direction of the road surface according to the same steps until the road is effectively separated. At this time, the base 1 is fixed to the ground by bolting to ensure the stability of the entire bracket system, and several sequentially extended circular double-layer protection frames 2 form a protection surface. The circular double-layer protection frame 2 is based on steel bars to form a double-layer circular structure, which increases the lateral and longitudinal stiffness of the guardrail bracket, can effectively absorb and disperse impact force from the outside, and can provide additional redundancy. Even if one layer is damaged, the other layer can still provide effective protection.

[0024] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
