Description

Technical Field

[0001] This utility model relates to the field of traffic safety technology, and in particular to a traffic safety isolation pier. Background Technology

[0002] Traffic barriers are traffic safety facilities installed at urban intersections, sidewalks, and between buildings to warn oncoming motor vehicles. They are typically placed along the sides or middle edge of roads and serve to indicate the direction of travel, possessing retroreflective properties and providing a degree of separation.

[0003] Patent document CN215669207U, entitled "A Traffic Safety Traffic Block," discloses that by incorporating water inlet / outlet holes, a combined support column unit, a limiting frame unit, and a plug block unit into the main body of the traffic block, the traffic block can achieve long-term stable use. This utility model has the following advantages: First, the main body of the traffic block does not directly contact the road, ensuring that it is not easily broken or leaks water, and guaranteeing sufficient weight; Second, the main body of the traffic block is movably connected to the traffic barrier, providing both sufficient connection strength and easy disassembly.

[0004] While the aforementioned median barriers are easy to disassemble and provide stable placement, sufficient weight is required for them to be truly stable. When the weight is particularly large, although disassembly is convenient, transportation and handling become very troublesome, making it difficult to move them by manpower. This is especially true when special vehicles need to use the road with median barriers, making it difficult to quickly remove them. Utility Model Content

[0005] This utility model discloses a traffic safety barrier, which aims to solve the technical problem that in order to be stable enough, the barrier must have sufficient weight. When the weight is particularly large, although it is easy to disassemble, its transportation and handling are very troublesome and difficult to move by manpower. In particular, when special vehicles need to pass through the road with barriers, it is difficult to quickly move the barriers.

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

[0007] A traffic safety barrier includes multiple supporting devices, with guardrails installed between each supporting device. Each supporting device includes a lifting part pre-installed underground. A column is installed above the lifting part, and the column is slidably connected to the lifting part via a connecting part. The connecting part includes a connecting plate, with a stud fixedly connected to the top of the connecting plate. The top of the stud extends into the column and is threadedly connected to it. A cross-shaped insert is provided on the lower surface of the connecting plate, and the bottom end of the cross-shaped insert is inserted into the lifting part and slidably connected to it. The connecting plate is fixedly connected to the cross-shaped insert via a brittle connecting post.

[0008] By setting up a support device, which includes a lifting unit and a column above the lifting unit, and the lifting unit is pre-installed below the ground, when the column needs to be used as a road barrier, the lifting unit moves the column upward to expose it above the ground, thus isolating the road surface. When the column is not needed, the lifting unit is used to move the column downward until it is completely lowered and embedded in the road surface. This effectively solves the awkward situation where road barriers need to be moved when they are not needed for temporary road isolation, but their weight makes them difficult to move.

[0009] By providing a connecting part, one end of which is fixedly connected to the column and the other end is slidably connected to the lifting part, and the connecting part is equipped with a brittle connecting column, so that when the vehicle makes a mistake and crashes into the column, the brittle connecting column will break under the impact force, thus effectively protecting the column and the lifting part and preventing them from deforming due to the large impact force.

[0010] In a preferred embodiment, the bottom of the lifting unit is fixedly connected to a pre-embedded base, the lifting unit includes an electric lifting column, the top of the electric lifting column is fixedly connected to a lifting plate, and adjustment parts are provided between the two ends of the upper surface of the lifting plate and the column.

[0011] By setting a pre-embedded base, which has a large area, the lifting unit can be effectively and stably installed on the road surface. Electric lifting bollards are an existing technology. They drive the lifting plate to move up and down, and the movement of the lifting plate drives the column to move up and down synchronously.

[0012] In a preferred embodiment, the adjusting part includes a rotating plate, one end of which is rotatably connected to the column, and the other end of which is rotatably connected to a T-shaped block, which is slidably connected to the lifting plate.

[0013] By setting up an adjustment mechanism, after the column is moved off the ground, when it is necessary to make a fine adjustment to the height of the column, simply slide the T-block, and with the support of the rotating plate, the column can be moved to make a small range of height adjustments.

[0014] In a preferred embodiment, the upper surface of the lifting plate is provided with a T-shaped groove that matches the T-shaped block, the upper surface of the lifting plate is provided with a bolt, the end of the bolt extends into the T-shaped groove and is threadedly connected to the T-shaped block, and the lifting plate is provided with a strip groove that mates with the bolt.

[0015] By setting and tightening the bolts, the position of the T-block can be fixed. The T-block slides, and with the cooperation of the strip groove, the bolts can slide synchronously without interference.

[0016] In a preferred embodiment, the guardrail includes two railings hinged at their ends, with insert plates fixedly connected to the ends of the two railings that are far apart from each other. The periphery of the post is provided with slots that match the insert plates, and rubber pads are fixedly connected to the sides of the insert plates. A limiting groove that matches the rubber pads is provided on the inner wall of the post located on the side of the slot.

[0017] By installing interlocking railings, when a vehicle slightly touches the railings, the hinged ends allow for some degree of avoidance, thus preventing bending and deformation.

[0018] In a preferred embodiment, one end of the railing is provided with a reinforcing rib, the end of which passes through both railings and is slidably connected to them.

[0019] By adding reinforcing ribs, the railings can be prevented from rotating automatically.

[0020] As can be seen from the above, the traffic safety isolation pier provided by this utility model has the following technical effects.

[0021] Firstly, by setting up a support device, which includes a lifting unit and a column positioned above the lifting unit, which is pre-installed below the ground, the column can be used as a road barrier when needed. The lifting unit moves the column upwards to expose it above the ground, thus isolating the road surface. When the column is no longer needed, the lifting unit can be used to move the column downwards until it is completely lowered and embedded in the road surface. This effectively solves the awkward situation where road barriers need to be moved when they are not needed for temporary road isolation, but their weight makes them difficult to move.

[0022] Secondly, by setting up a connecting part, one end of which is fixedly connected to the column and the other end is slidably connected to the lifting part, and the connecting part is equipped with a brittle connecting column, so that when the vehicle makes a mistake and crashes into the column, the brittle connecting column will break under the force of a large impact, thus effectively protecting the column and the lifting part and preventing them from deforming due to a large impact force.

[0029] 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.

[0030] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Reference Figures 1-5A traffic safety barrier includes multiple support devices 1, with guardrails 2 installed between each support device 1. Each support device 1 includes a lifting part 4 pre-installed underground. A column 5 is installed above the lifting part 4. The column 5 is slidably connected to the lifting part 4 via a connecting part 7. The connecting part 7 includes a connecting plate 72. A stud 73 is fixedly connected to the top of the connecting plate 72. The top of the stud 73 extends into the column 5 and is threadedly connected to it. A cross-shaped insert 71 is provided on the lower surface of the connecting plate 72. The bottom end of the cross-shaped insert 71 is inserted into the lifting part 4 and slidably connected to it. The connecting plate 72 is fixedly connected to the cross-shaped insert 71 via a brittle connecting post 74.

[0032] In this embodiment, a support device 1 is provided, which includes a lifting part 4 and a column 5 is set above the lifting part 4. The lifting part 4 is preset below the ground. When the column 5 needs to be used as a barrier, the lifting part 4 moves the column 5 upward to protrude from the ground, thereby isolating the road surface. When the column 5 is not needed, the lifting part 4 is used to move the column 5 downward until it is completely lowered and embedded in the road surface. This effectively solves the awkward situation that when the barrier is not needed for road isolation, it is necessary to move the barrier, but its weight is too large and it is difficult to move.

[0033] By providing a connecting part 7, one end of which is fixedly connected to the column 5 and the other end is slidably connected to the lifting part 4, and the connecting part 7 is provided with a brittle connecting column 74, so that when the vehicle makes a driving error and crashes into the column 5, the brittle connecting column 74 will break under the large impact force, thereby effectively protecting the column 5 and the lifting part 4 and preventing them from deforming due to the large impact force.

[0034] Reference Figure 1 and Figure 4 In a preferred embodiment, the bottom of the lifting part 4 is fixedly connected to a pre-embedded base 3, the lifting part 4 includes an electric lifting column 41, the top of the electric lifting column 41 is fixedly connected to a lifting plate 42, and adjustment parts 6 are provided between the two ends of the upper surface of the lifting plate 42 and the column 5.

[0035] In this embodiment, by setting a pre-embedded base 3, the pre-embedded base 3 has a large area, which can effectively make the lifting part 4 stably set in the road surface. The electric lifting column 41 is the prior art, which drives the lifting plate 42 to move up and down. The lifting plate 42 moves up and down, which drives the column 5 to move up and down synchronously.

[0036] Reference Figure 1 and Figure 4 In a preferred embodiment, the adjustment unit 6 includes a rotating plate 62, one end of which is rotatably connected to the column 5, and the other end of which is rotatably connected to a T-shaped block 61, which is slidably connected to the lifting plate 42.

[0037] In this embodiment, by setting the adjustment part 6, when the height of the column 5 needs to be finely adjusted after the column 5 is moved off the ground, simply slide the T-shaped block 61, and with the support of the rotating plate 62, the column 5 can be driven to make a small range of height adjustment.

[0038] Reference Figure 1 and Figure 4 In a preferred embodiment, the upper surface of the lifting plate 42 is provided with a T-shaped groove 421 that matches the T-shaped block 61, and a bolt 63 is provided on the upper surface of the lifting plate 42. The end of the bolt 63 extends into the T-shaped groove 421 and is threadedly connected to the T-shaped block 61. The lifting plate 42 is provided with a strip groove 422 that cooperates with the bolt 63.

[0039] In this embodiment, by setting bolt 63 and tightening bolt 63, the position of T-block 61 can be fixed. T-block 61 slides, and with the cooperation of strip groove 422, bolt 63 can slide synchronously without interference.

[0040] Reference Figure 1 and Figure 3 In a preferred embodiment, the guardrail 2 includes two railings 21 with their ends hinged together. Each of the two railings 21 has a fixed plate 211 at one end that is far apart from the other. The periphery of the post 5 is provided with a slot 51 that matches the slot 211. A rubber pad 212 is fixedly connected to the side of the slot 211. A limiting groove 52 that matches the rubber pad 212 is provided on the inner wall of the post 5 located on the side of the slot 51.

[0041] In this embodiment, by setting up mutually hinged railings 21, when a vehicle slightly touches the railings 21, the hinged ends of the railings can avoid the vehicle to a certain extent, thereby preventing bending deformation.

[0042] Reference Figure 1 and Figure 3 In a preferred embodiment, one end of the railing 21 is provided with a reinforcing rib 22, the end of the reinforcing rib 22 passing through the two railings 21 and slidably connected thereto.

[0043] In this embodiment, by providing reinforcing ribs 22, the railing 21 can be prevented from rotating automatically under the airflow of the vehicle.

[0044] Working principle: When in use, simply start the electric lifting column 41. The electric lifting column 41 will drive the column 5 to rise and move out of the ground. Then, the guardrail 2 can be directly installed on the column 5 through the slot 51 to isolate the road surface. When it is necessary to remove the isolation function of the column 5 for a short time, simply turn off the electric lifting column 41 and drive the column 5 to move down and retract into the ground. When the column 5 is retracted into the ground, the guardrail 2 will detach from the column 5 due to the obstruction of the road surface. At this time, people nearby only need to move the railing 21 to the road surface.

[0045] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
