Technical Field

[0001] The utility model relates to the technical field of guardrail structures, and particularly relates to an anti-collision guardrail with good buffering performance. Background Art

[0002] A guardrail refers to a guardrail set beside a road. Its purpose is to prevent out-of-control vehicles from going out of the bridge, and it has the functions of preventing vehicles from breaking through, passing under, or climbing over the bridge, as well as beautifying the bridge structure.

[0003] For existing guardrails, when being impacted, they all resist the energy generated by the impact through the material hardness of the guardrail itself. If the impact energy is too large, the guardrail itself is extremely likely to suffer irreparable damage, thus requiring the replacement of a new guardrail.

[0004] Therefore, it is necessary to propose an anti-collision guardrail with good buffering performance. Compared with the anti-collision guardrail of the prior art, its buffering performance is greatly improved, so as to avoid the irreparable damage of the guardrail itself when it is impacted by excessive energy. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and propose an anti-collision guardrail with good buffering performance, whose buffering performance is greatly improved, so as to avoid the irreparable damage of the guardrail itself when it is impacted by excessive energy.

[0006] The purpose of the utility model is achieved through the following technical solutions: an anti-collision guardrail with good buffering performance, including multiple columns. T-shaped grooves are formed in the columns along their elongation directions. A plurality of anti-blocks are arranged on one side of the columns far away from the openings of the T-shaped grooves. A corrugated beam plate is arranged on the anti-blocks.

[0007] Grooves are formed in the anti-blocks along their elongation directions. Connection parts connected to both sides of the anti-blocks are arranged at the openings of the grooves. The connection parts are connected to the columns through first locking bolts.

[0008] The protection plate is connected to the anti-block through a second locking bolt.

[0009] Installation shells matching the number and positions of the anti-blocks are arranged on the columns. The interiors of the installation shells are hollow. First sliders are slidably arranged in the installation shells. The anti-blocks are slidably arranged through the installation shells and fixedly connected to the first sliders. First sliding rods are slidably arranged through the installation shells and the columns. The first sliding rods are connected to the first sliders. First return springs are sleeved on the first sliding rods.

[0010] The first slider is a first wedge block, a second wedge block is slidably arranged in the mounting shell, the inclined surfaces of the first wedge block and the second wedge block are slidably connected, and a second return spring for driving the second wedge block to move is further included.

[0011] A fixing part is arranged on the column, a second sliding rod is slidably penetrated through the fixing part, the second sliding rod is connected with the second wedge block, a collar is fixedly sleeved on the second sliding rod, and the second return spring is sleeved on the second sliding rod and its two ends are respectively connected with the collar and the fixing part.

[0012] The protective plate is a corrugated beam plate.

[0013] The beneficial effects of the present utility model are as follows: by providing a T-shaped groove and an anti-blocking block on the column, when the protective plate is violently impacted, the anti-blocking block can buffer it and absorb the impact energy received by the protective plate. Since the column is provided with a T-shaped groove, it can also undergo corresponding deformation to absorb the impact energy received by the protective plate, thereby greatly improving the buffering performance of the present utility model.

Detailed Embodiments

[0020] The technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0021] It should be noted that in the following solutions, the orientation concepts of "left", "right", "up", "down", "front", "back", "inside", and "outside" are all relative directions, and will not be listed one by one here.

[0022] An anti-collision guardrail with good buffering performance, refer to Figures 1 - 4 , including a plurality of columns 1. A T-shaped groove 11 is opened on the rear side of the column 1 along its elongation direction. An anti-collision block 2 is detachably arranged on the front side of the column 1. A corrugated beam plate 5 is detachably arranged on the front side of the anti-collision block 2.

[0023] A slot 21 is opened on the rear side of the anti-collision block 2 along its elongation direction. Connecting portions 22 are arranged on both side walls of the anti-collision block 2. The connecting portions 22 are detachably connected to the column 1 through first locking bolts 23, so as to realize the detachable connection between the anti-collision block 2 and the column 1. The corrugated beam plate 5 is detachably connected to the anti-collision block 2 through a second locking bolt 24.

[0024] By opening the T-shaped groove 11 on the column 1 and arranging the anti-collision block 2, and opening the slot 21 on the anti-collision block 2, when the corrugated beam plate 5 is violently impacted, the anti-collision block 2 can buffer it and absorb the impact energy received by the corrugated beam plate 5. Since the T-shaped groove 11 is opened on the column 1 and the slot 21 is opened on the anti-collision block 2, the two can also undergo corresponding deformation to absorb the impact energy received by the corrugated beam plate 5, thereby greatly improving the buffering performance of the present utility model.

[0025] As a further improvement of the present utility model, it can be further extended according to the above case to provide a variety of new embodiments.

[0026] As the second embodiment of the present utility model, on the basis of Embodiment 1, refer to Figure 5 , an installation shell 3 which is hollow inside and matches the number, position and size of the anti-collision blocks 2 is arranged on the front side of the column 1. The anti-collision block 2 is slidably arranged through the installation shell 3 from left to right. A first wedge-shaped block 31 is slidably arranged in the installation shell 3 from left to right, and the right side of the first wedge-shaped block 31 is an inclined surface. The first wedge-shaped block 31 is connected to the anti-collision block 2. Two first sliding rods 32 are arranged on the first wedge-shaped block 31. The first sliding rods 32 are slidably arranged through the column 1 and the installation shell 3. A first return spring 33 is sleeved on the first sliding rods 32, and both ends of the first return spring 33 are abutted against the first wedge-shaped block 31 and the inner wall of the installation shell 3 respectively.

[0027] A second wedge block 34 is slidably arranged in the mounting shell 3 from top to bottom. The left side of the second wedge block 34 is an inclined surface and is slidably connected to the inclined surface of the first wedge block 31. A second sliding rod 41 is arranged on the lower side of the second wedge block 34. The second sliding rod 41 is slidably arranged through the mounting shell 3. A fixing part 4 is arranged on the front side of the upright column 1. The second sliding rod 41 is slidably arranged through the fixing part 4. A collar 42 is fixedly sleeved on the second sliding rod 41. A second return spring 35 is sleeved on the second sliding rod 41. The two ends of the second return spring 35 are respectively abutted against the collar 42 and the fixing part 4.

[0028] When the corrugated beam plate 5 is impacted, the anti-blocking block 2 moves from left to right in the mounting shell 3, thereby pushing the first wedge block 31 to move leftward and the second wedge block 34 to move downward. The first return spring 33 and the second return spring 35 are deformed, thereby absorbing the impact energy and further improving the buffering performance.

[0029] The above are only the preferred embodiments of the present invention.
