Description

Technical Field

[0001] The utility model relates to the technical field of anti-blocking blocks, in particular to a guardrail buffer anti-blocking block. Background Art

[0002] The block is a spare part of the corrugated guardrail of the road, and is mainly used as a load-bearing component between the corrugated beam and the column of the highway. In the current transportation technology system, the block is cleverly designed as an efficient energy-absorbing mechanism. When the guardrail encounters a collision, the block can gradually deform using its unique hollow structure, thereby effectively absorbing part of the energy generated by the impact. This design not only significantly reduces the risk of casualties of passengers, but also improves the overall protection performance of the guardrail.

[0003] However, although the hollow structure of the anti-block performs well in absorbing impact energy, it also exposes its limitations when facing strong impacts. Due to the design of the hollow structure, the anti-block may appear relatively soft when hit by a strong impact, which may result in the vehicle not being effectively cushioned and then colliding with the roadbed, causing serious damage to the vehicle. Utility Model Content

[0004] The utility model aims to solve one of the technical problems in the related art at least to a certain extent.

[0005] To this end, one purpose of the utility model is to provide a guardrail buffer block, which increases the energy absorption effect and structural strength of the block by increasing the structure of the block itself, thereby reducing the damage to the vehicle after the collision.

[0006] To achieve the above-mentioned purpose, the utility model proposes a guardrail buffer block, comprising a support frame, a mounting assembly, a fixing assembly and a buffer assembly, wherein the mounting assembly is fixedly connected to the support frame; the support frame is connected to the column through the fixing assembly; the buffer assembly is fixedly connected to the support frame, and the buffer assembly comprises a mounting rod, a buffer spring, a buffer rod and a honeycomb buffer plate, wherein the two ends of the mounting rod are respectively fixedly connected to the buffer spring and the support frame, the buffer rod is fixedly connected to one end of the buffer spring away from the mounting rod, and the buffer rod passes through the mounting rod and the mounting assembly; the honeycomb buffer plates are provided in two groups, and the two groups of honeycomb buffer plates are respectively installed at the two ends inside the support frame.

[0007] The guardrail buffer block of the utility model improves the strength of the support frame by adding a buffer component inside the support frame, and completes the installation of the support frame on the column under the action of the installation component and the fixing component. When impacted, the impact is buffered by the installation rod, the buffer spring and the buffer rod, and the kinetic energy generated by the impact is absorbed under the action of the installation component to reduce the damage to the vehicle. The energy absorption effect and structural strength of the barrier block are increased by increasing the structure of the barrier block itself, thereby reducing the damage to the vehicle after the impact.

[0019] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0020] The guardrail buffer block according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0021] The guardrail buffer block provided in the embodiment of the utility model can be used for protection on both sides of the highway. The energy absorption effect and structural strength of the block are increased by increasing the structure of the block itself, thereby reducing the damage to the vehicle after the collision.

[0022] like Figure 1-Figure 3 As shown, the guardrail buffer block of the embodiment of the utility model may include a support frame 1, an installation component 2, a fixing component 3 and a buffer component 4.

[0023] It should be noted that a through slot (not shown in the figure) for connecting the guardrail is provided on the side of the support frame 1 away from the fixing assembly 3 .

[0024] Wherein, the mounting assembly 2 is fixedly connected to the supporting frame 1 .

[0025] It should be noted that, under the action of the mounting assembly 2 , both sides of the support frame 1 are protected after being impacted.

[0026] The support frame 1 is connected to the column through a fixing assembly 3 .

[0027] It is understandable that the support frame 1 can be connected to the column through the fixing component 3.

[0028] The buffer assembly 4 is fixedly connected to the support frame 1 , and the buffer assembly 4 may include a mounting rod 41 , a buffer spring 42 , a buffer rod 43 and a honeycomb buffer plate 44 .

[0029] It should be noted that the mounting rods 41 , buffer springs 42 and buffer rods 43 described in the above embodiments are each provided in two groups, and buffer springs 42 of corresponding strength can be selected according to the application scenario of the support frame 1 .

[0030] The two ends of the mounting rod 41 are fixedly connected to the buffer spring 42 and the support frame 1 respectively, the buffer rod 43 is fixedly connected to one end of the buffer spring 42 away from the mounting rod 41, and the buffer rod 43 passes through the mounting rod 41 and the mounting assembly 2.

[0031] It can be understood that when the support frame 1 is hit, the buffer spring 42 and the buffer rod 43 will be squeezed by the mounting rod 41, and the buffer spring 42 will contract to absorb the kinetic energy, and the kinetic energy will be consumed through the friction between the buffer rod 43 and the mounting assembly 2, thereby reducing the degree of damage when the vehicle hits the support frame 1 and protecting the people inside the vehicle.

[0032] Two groups of honeycomb buffer plates 44 are provided, and the two groups of honeycomb buffer plates 44 are respectively installed at two ends inside the support frame 1 .

[0033] It should be noted that, since the honeycomb buffer plate 44 uses the honeycomb's anti-vibration characteristics to reinforce the two ends of the support frame 1, it does not affect the use of the support frame 1 and further increases the structural strength of the support frame 1.

[0034] Specifically, in the actual operation process, when the relevant personnel install the support frame 1, they connect it to the column through the fixing component 3, and under the action of the installation component 2, further protect the two sides of the support frame 1. At the same time, when the support frame 1 is hit, the buffer spring 42 and the buffer rod 43 will be squeezed by the installation rod 41. At the same time, the buffer spring 42 contracts to absorb kinetic energy, and the friction between the buffer rod 43 and the installation component 2 is used to consume the kinetic energy, thereby achieving the effect of reducing the degree of damage when the vehicle hits the support frame 1 and protecting the people inside the vehicle. At the same time, due to the honeycomb anti-seismic characteristics of the honeycomb buffer plate 44, the two ends of the inside of the support frame 1 are reinforced. Without affecting the use of the support frame 1, the structural strength of the support frame 1 is further increased, and the energy absorption effect and structural strength of the anti-blocking block are increased by increasing the structure of the anti-blocking block itself, thereby reducing the damage to the vehicle after the collision.

[0035] In one embodiment of the present invention, Figure 1-Figure 2 As shown, the outer sides of the honeycomb buffer plates 44 are fixedly connected to the limiting plates, and the interior of the support frame 1 is provided with limiting grooves for the limiting plates to be engaged.

[0036] It is understandable that the connection between the limiting plate and the limiting groove facilitates the replacement of the honeycomb buffer plate 44 and also facilitates the installation of the mounting rod 41 , the buffer spring 42 and the buffer rod 43 .

[0037] In one embodiment of the present invention, Figure 1-Figure 2 As shown, the mounting assembly 2 may include an abutment frame 21 , a connecting rod 22 , a mounting plate 23 and a rubber plate 24 .

[0038] It should be noted that, in the above embodiment, two groups of abutment frames 21 are provided, and both groups of abutment frames 21 abut against the support frame 1 .

[0039] Among them, the abutment frame 21 is fixedly connected to the connecting rod 22, and two groups of connecting rods 22 are provided. Both groups of connecting rods 22 are fixedly connected to the mounting plate 23, the rubber plate 24 is fixedly connected to the mounting plate 23, and the buffer rod 43 passes through the mounting plate 23 and the rubber plate 24, and the outer side of the buffer rod 43 abuts against the inner side of the rubber plate 24.

[0040] Specifically, the support frame 1 is supported by the abutment frame 21, and the abutment frame 21 is installed on the column by the connection rod 22 and the mounting plate 23. At the same time, the kinetic energy generated by the sliding of the buffer rod 43 is reduced by the rubber plate 24.

[0041] In one embodiment of the present invention, Figure 1-Figure 2 As shown, the fixing assembly 3 may include a No. 1 nut 31 , a screw rod 32 , a No. 2 nut 33 and a sleeve 34 .

[0042] It should be noted that the corresponding sleeve 34 can be selected according to the size of the column to facilitate the installation and fixation of the support frame 1.

[0043] Among them, the No. 1 nut 31 is set on one side of the rubber plate 24, one end of the screw rod 32 is threadedly penetrated through the No. 1 nut 31 and the mounting assembly 2 to extend to the inside of the support frame 1, the No. 2 nut 33 is set inside the support frame 1, and the No. 2 nut 33 is threadedly connected to the other end of the screw rod 32. The sleeve 34 is set between the two groups of connecting rods 22. The middle part of the sleeve 34 is provided with a through hole 35 for the column to be inserted, and the screw rod 32 is set through the sleeve 34.

[0044] Specifically, the through hole 35 opened on the sleeve 34 is used to be sleeved with the column, and the screw 32 passes through the rubber plate 24, the mounting plate 23 and the sleeve 34, and one end of the screw 32 is connected by the No. 2 nut 33, and under the action of the No. 1 nut 31, the connection of the other end of the screw 32 is completed, and the support frame 1 can be fixed on the column.

[0045] In one embodiment of the present invention, Figure 1-Figure 2 As shown, a leather gasket is fixedly connected to the inner side of the through hole 35 .

[0046] It can be understood that the friction between the through hole 35 and the column can be increased by the leather washer, thereby ensuring the stability of the support frame 1 installed on the column.

[0047] In summary, the guardrail buffer block of the utility model embodiment improves the strength of the support frame by adding a buffer component inside the support frame, and completes the installation of the support frame on the column under the action of the mounting component and the fixing component. When impacted, the impact is buffered by the mounting rod, the buffer spring and the buffer rod, and the kinetic energy generated by the impact is absorbed under the action of the mounting component to reduce the degree of damage to the vehicle. The energy absorption effect and structural strength of the block are increased by increasing the structure of the block itself, thereby reducing the damage to the vehicle after the impact.
