Description

TECHNICAL FIELD

[0001] The utility model relates to the field of highway traffic safety facilities, in particular to a highway crash barrier anti-blocking block. BACKGROUND

[0002] Highway traffic safety has always been an important issue of social concern. As an important part of highway safety facilities, the performance of crash barriers is directly related to the safety of life and property of vehicles and pedestrians. The inventor knows that the highway crash barrier includes a column with a fixing function, a corrugated beam guardrail plate for directly receiving the impact of a car, and a highway crash barrier anti-blocking block connecting the column and the corrugated beam guardrail plate. The traditional highway crash barrier anti-blocking block mainly plays the role of supporting and connecting the corrugated beam guardrail plate and the column, so that the corrugated beam guardrail plate and the column form a whole. However, when the highway crash barrier is subjected to a collision and the collision energy reaches a certain degree, the traditional anti-blocking block is prone to deformation under pressure, which may cause the corrugated beam guardrail plate and the column to collapse together, thereby possibly causing the vehicle to cross the guardrail and rush out of the roadside. The design of such traditional anti-blocking block has obvious shortcomings in dealing with larger impact forces, and cannot effectively protect the safety of vehicles and personnel.

[0003] In actual highway traffic, vehicle collisions with the guardrail occur from time to time. Due to the structural and performance limitations of the traditional anti-blocking block, once a serious collision occurs, it is often unable to effectively absorb and disperse the collision energy, and cannot well control the degree of deformation and damage of the guardrail. This not only may cause the vehicle to be more severely damaged, but also may cause more serious traffic accidents, causing huge losses to society.

[0004] In addition, the manufacturing materials and processes of the traditional anti-blocking block also have certain limitations, and its strength and durability may not meet the growing demand for traffic safety. With the continuous increase of highway traffic flow and the increase of vehicle driving speed, the performance requirements for the anti-blocking block of the crash barrier are also becoming higher and higher. Therefore, it is of great practical significance and urgency to develop a new type of highway crash barrier anti-blocking block with superior performance. UTILITY MODEL CONTENTS

[0033] It should be noted that the same reference signs in the embodiments of the present application represent the same component or the same part.

[0034] The utility model discloses a kind of highway crash barrier block, to solve the problems existing in prior art, make highway crash barrier block easy to deform when being impacted, thereby cutting off the bolt between wave beam guardrail plate and highway crash barrier block, prevent wave beam guardrail plate from lodging, let wave beam guardrail plate can always block car, avoid car across guardrail and rush out road surface, guarantee the safety of vehicle and personnel in vehicle.

[0035] The utility model still provides a highway crash barrier, including above -mentioned highway crash barrier prevents resistance block, when the vehicle hits the guardrail, the corrugated beam guardrail board first uplifts, passes through the displacement and deformation of corrugated beam guardrail board absorption collision energy, promotes the buffering effect. With the continuous increase of impact force, the highway crash barrier prevents resistance block and continues to deform to a certain extent under pressure, will distort and produce shear force, shear the connecting bolt of connecting corrugated beam guardrail board, and the corrugated beam guardrail board and the resistance block, the column are separated, can continue to play the role of blocking and buffering, effectively avoid the vehicle to rush out the guardrail, guarantee the traffic safety.

[0036] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the utility model will be further described in detail below with the help of the drawings and specific embodiments.

[0037] As Figures 1-7 The utility model provides a highway crash barrier prevents resistance block, including main frame 1, main frame 1 is the parallelogram structure of the board material combination, and the wide surface of board material is parallel to the axis of main frame 1, and every long side of main frame 1 is provided with first bolt hole 101, still including support plate 2, and the both ends of support plate 2 are provided with the lug plate 202 with second bolt hole 201, and support plate 2 is arranged in main frame 1, and lug plate 202 is fixed on different long side respectively, and second bolt hole 201 is aligned with first bolt hole 101, and support plate 2 is parallel to the short side of main frame 1. The structure of parallelogram is easy to deform when being impacted, and main frame 1 and support 2 can cut off the bolt passing through first bolt hole 101 and second bolt hole 201 after deformation, so that the corrugated beam guardrail board and the highway crash barrier prevents resistance block are separated, and support plate 2 can construct a new parallelogram structure in the main frame 1, and the deformation effect is enhanced. Figure 3 The axis of main frame 1 is marked, and the wide surface of the board material is used as the mounting surface of the connecting piece.

[0038] In an embodiment, main frame 1 and support plate 2 are fixed by welding, and main frame 1 and support plate 2 can also be fixed by using other methods.

[0039] As Figures 1-3 In an embodiment, one long side of main frame 1 is an intermittent structure. Main frame 1 is a non-sealed structure, which further reduces the bearing capacity of main frame 1, and main frame 1 can deform faster and cut off the bolt earlier when being impacted. The intermittent structure can be arranged above support plate 2 and on the same side as the lower end of support plate 2.

[0040] In an embodiment, main frame 1 is a closed structure. The closed structure needs a larger impact force to deform, so when main frame 1 deforms, its own deformation force will also increase, resulting in an increase in the shear force on the bolt, and the cutting effect is better.

[0041] In one embodiment, the support plate 2 and the main frame 1 together form a sealed rhomboid structure. The rhomboid structure has four sides of equal length, resulting in rapid propagation of impact force and rapid deformation.

[0042] like Figure 4 As shown, in one embodiment, there are two ear plates 202, which are located at opposite ends of the support plate 2, and the extension directions of the two ear plates 202 are opposite. The extension directions of the ear plates 202 can also be kept in the same direction, and the number of ear plates 202 can be adjusted as needed.

[0043] In one embodiment, the main frame 1 is made of stainless steel or low-alloy high-strength steel, and the support plate 2 is also made of stainless steel or low-alloy high-strength steel. Low-alloy high-strength steel refers to low-alloy engineering structural steel in which a small amount of alloying elements are added to low-carbon steel, resulting in a yield strength exceeding 275 MPa in the rolled or normalized state. Stainless steel or low-alloy high-strength steel can meet the daily use requirements of highway crash barrier blocks, preventing damage and failure caused by severe weather conditions such as low temperatures, high temperatures, strong winds, rain, and hail. During manufacturing, stainless steel plates or low-alloy high-strength structural steel plates are selected as raw materials according to actual needs. The steel plates are cut and stamped to process the required main frame 1 and support plate 2. When the main frame 1 is a closed structure, sealing can be achieved through welding or other methods. Then, the main frame 1 and support plate 2 are assembled in a specific manner, tightly connected to form a vertical structure. Other materials that meet the usage requirements can also be used for the main frame 1 and support plate 2.

[0044] In one embodiment, the thickness of the plate of the main frame 1 is 2 mm to 6 mm, the width of the plate of the main frame 1 is 100 mm to 190 mm, the height of the main frame 1 is 200 mm to 500 mm, the thickness of the support plate 2 is 2 mm to 6 mm, and the width of the support plate 2 is 100 mm to 190 mm.

[0045] like Figure 8 As shown, during installation, the highway crash barrier anti-collision block provided by this utility model has one long side fixedly connected to the corrugated beam guardrail plate 3 by bolts, and the other long side fixedly connected to the post 4 by bolts. The end of the short side of the main frame 1 near the corrugated beam guardrail plate 3 is higher than the end of the short side of the main frame 1 near the post 4. This higher position ensures that when the highway crash barrier anti-collision block is impacted, it deforms upwards, thereby lifting the corrugated beam guardrail plate 3. The displacement and deformation of the corrugated beam guardrail plate 3 absorbs collision energy, improving the buffering effect. When the highway crash barrier anti-collision block cuts the bolts connecting the corrugated beam guardrail plate 3, the corrugated beam guardrail plate 3 separates from the highway crash barrier anti-collision block and the post 4, but can still continue to play a blocking and buffering role, effectively preventing vehicles from running off the guardrail and ensuring driving safety.

[0046] As Figure 8 shown, in an embodiment, one long side of the main frame 1 is discontinuous structure, the discontinuous long side is connected with the column 4, and the other long side is connected with the wave beam guardrail plate 3.

[0047] In an embodiment, the bolt for connection is a common bolt.

[0048] It should be noted that, for those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
