Detailed Description
An embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the embodiment.
In the present application, the type and structure of components that are not specified are all the prior art known to those skilled in the art, and those skilled in the art can set the components according to the needs of the actual situation, and the embodiments of the present application are not specifically limited.
Specifically, as shown in fig. 1, an embodiment of the present invention provides a movable fence, including: division board 1, a plurality of guardrail 4, buffer gear 3 and buffer layer. Wherein, the division board 1 is arranged longitudinally along the yellow line of the road. A plurality of guardrail 4 sets up respectively one side of division board 1, adjacent two guardrail 4 articulates on the relative both sides face of a bracing piece 5 through first articulated elements respectively, the bottom of bracing piece 5 is provided with first gyro wheel 6. One end of the buffer mechanism 3 is connected to the isolation plate 1, and the other end is connected to the guardrail 4 or the support rod 5. The buffer layer is uniformly arranged on one surface of the isolation plate 1 facing the guardrail 4.
In the middle of the current road, a traffic department can draw a yellow line on the road surface, so that the vehicles coming and going take the yellow line as decomposition respectively, and the opposite directions are carried out on the two sides of the yellow line. Therefore, the invention arranges the isolation board 1 on the yellow line, so that the vehicle can respectively run on two sides of the isolation board 1 when running. When the guardrail is used, the guardrail has two states, wherein one state is a normal state, namely a state that no running vehicle collides with the guardrail, and the other state is a collision state, namely a state that the running vehicle collides with the guardrail.
When the invention is in a normal state, the guardrail 4 and the support rod 5 are positioned at one side of the isolation plate 1 and have a certain distance with the isolation plate 1, the distance is the length distance of the buffer mechanism 3 when the buffer mechanism is not buffered, in the normal state, some flowers and plants can be planted between the guardrail 4 and the support rod 5 and the isolation plate 1, and the buffer mechanism 3 only needs to penetrate through the planted flowers and plants, so that the attractiveness of the middle of a road can be improved, and the greening effect on the environment can be achieved.
When the invention is in a collision state, a vehicle is firstly collided on the guardrail 4, the guardrail 4 and the support rod 5 play a certain role in blocking the collision of the vehicle, so that the kinetic energy generated by the collision of the vehicle is balanced out to a certain extent, if the collision power of the vehicle still exists, the guardrail 4 and the support rod 5 can move towards one side of the partition board 1, at the moment, the buffer mechanism 3 plays a role in buffering, so that the kinetic energy generated by the collision of the vehicle is balanced out to a certain extent again, if the collision power of the vehicle still exists, the buffer layer can be reached, the kinetic energy generated by the collision of the vehicle is balanced out to a certain extent again, and thus the kinetic energy generated by the collision of the vehicle is greatly reduced through the buffer of multiple layers, so that the vehicle can gradually eliminate the collision kinetic energy under the buffer effect and stop gradually, finally, the casualty accidents of the personnel are reduced.
In this embodiment, the buffer mechanism 3 is connected to the support rod 5. Connect buffer gear 3 on bracing piece 5, can be so that the connection more firm, because the length of the cross section of bracing piece 5 is less than the length of the cross section of guardrail 4, just so make when colliding, buffer gear 3 is not fragile, and guardrail 4 and bracing piece 5 are also difficult to damage.
Meanwhile, in the present embodiment, the damper mechanism 3 includes: a plurality of connecting rods 3-2, telescopic rods 3-3 and second rollers 3-4. The head and the tail of each connecting rod 3-2 in the connecting rods 3-2 are sequentially hinged through a second hinge piece, the connecting rod 3-2 closest to the isolation plate 1 is hinged with the isolation plate 1, and the connecting rod 3-2 closest to the support rod 5 is hinged with the support rod 5.

The second roller 3-4 is arranged at the bottom of the telescopic rod 3-3.
The working principle of the technical scheme is that in a normal state, as shown in fig. 2, the connecting rods 3-2 are positioned on the same straight line, in a normal state, as shown in fig. 3, the connecting rods 3-2 are bent, the kinetic energy is offset through different state changes among the connecting rods 3-2, and in the force applying process, the shapes of the connecting rods 3-2 positioned on the same straight line are changed, so that the connecting rods 3-2 are bent. In the invention, the telescopic rods 3-3 with variable lengths keep the fixed points of the connecting rods 3-2 unchanged, so that the connecting rods 3-2 cannot be damaged when the state is changed, and meanwhile, the second rollers 3-4 at the bottom play a role in facilitating movement, which is consistent with the role of facilitating movement of the supporting rod 5 by the first rollers 6.
Meanwhile, in the present embodiment, the second hinge is a torsion spring 3-1. The torsion spring 3-1 is used as the second hinge part to enable a force action to be generated between two adjacent connecting rods 3-2, so that when a vehicle collides, the acting force between two adjacent connecting rods 3-2 enables the supporting rod 5 to be less likely to be close to the partition board 1, and therefore kinetic energy generated by the vehicle collision is offset to a certain extent.
Meanwhile, in this embodiment, the movable guardrail provided by the embodiment of the invention further comprises an electromagnetic buffer area. The electromagnetic buffer zone comprises a plurality of electromagnets 7 embedded in the road and positioned below the buffer mechanism 3, the telescopic rods 3-3 and the guardrail 4; the electromagnetic buffer area consists of a plurality of magnetic areas distributed along the trend of the guardrail 4, each magnetic area consists of a plurality of electromagnets 7, and the magnetic force of each magnetic area is the magnetic force of each electromagnet 7 in the magnetic area; the magnitude of the magnetic force of each magnetic field is inversely related to the distance of the magnetic field from the separator 1. The first roller 6 and the second rollers 3-4 are both made of iron.
In the present invention, as shown in fig. 2-3, the magnitude of the magnetic force is sequentially weakened along the direction pointed by the arrow in the figure, so that the magnetic force of the electromagnet 7 farther from the magnetic force area of the partition board 1 is smaller, and since the first roller 6 and the second roller 3-4 are made of iron, the first roller 6 and the second roller 3-4 are attracted by the magnetic force generated by the electromagnet 7 when rolling, so that the force required for rolling can be increased when the first roller 6 and the second roller 3-4 roll, and the rolling speed is reduced. Therefore, the support rod 5 is made more and more difficult to approach the partition board 1 when the first roller 6 and the second rollers 3 to 4 are rolling, so that the kinetic energy generated by the vehicle collision is somewhat offset at the time of the vehicle collision.
Meanwhile, in the present embodiment, the upper surface of the electromagnet 7 is on the same plane as the road surface. Thus, the road surface looks flat in appearance.
In this embodiment, the buffer layer is a plurality of buffer cushions 2, and the plurality of buffer cushions 2 are uniformly and densely distributed on the surface of the isolation board 1. The buffer air cushion 2 is a buffer defense line generated between the collision of the vehicle and the partition board 1, and aims to offset the kinetic energy generated by the collision of the vehicle to a certain extent through buffering.
In this embodiment, the guardrail 4 is of an inflatable structure. The guardrail 4 of the inflatable structure can buffer the automobile body of the automobile to a certain extent when the automobile collides, and meanwhile, the flexibility of the guardrail can greatly reduce the kinetic energy of the automobile collision under the condition of not damaging the automobile body, thereby reducing the casualty accidents of people
Meanwhile, in the present embodiment, the guard rail 4 includes: a plurality of inflatable bladders 4-2 and voids 3-1. Each inflatable airbag 4-2 in the plurality of inflatable airbags 4-2 is in a strip shape, and the plurality of strip-shaped inflatable airbags 4-2 are distributed in a transversely-longitudinally staggered mode. Gaps 3-1 are positioned between the inflatable air bags 4-2 which are distributed in a crisscross way.
The inflatable air bag 4-2 can buffer the automobile body of the automobile when the automobile collides, and meanwhile, the flexibility of the inflatable air bag 4-2 can greatly reduce the kinetic energy of the automobile collision under the condition of not damaging the automobile body, so that the casualty accidents of people are reduced. Meanwhile, the gaps 3-1 distributed among the inflatable air bags 4-2 in a transversely and longitudinally staggered manner are matched, and according to the basic principle of aerodynamics, the gaps 3-1 can further enhance the buffering effect and greatly reduce the kinetic energy of automobile collision under the condition of not damaging the automobile body.
When installing above-mentioned portable guardrail, need a transportation installation construction platform truck, be provided with a plurality of blowing districts 9 of different shape size on its mesa 8, the quantity of blowing district 9 equals with the quantity of the material kind of above-mentioned portable guardrail.
