Description

High energy dissipation anti-collision device

technical field

The utility model relates to the field of road facilities, in particular to a high energy dissipation anti-collision device.

Background technique

With the rapid development of highway construction in our country, the mileage of highway traffic has increased rapidly, but the road traffic safety problems brought about by it have become increasingly prominent. Highway anti-collision barrier is one of the most important safety protection facilities. It plays an important role in the development of national economy and society, and is an important safety guarantee facility for highways.

At present, anti-collision guardrails are installed on both sides of the road. Among them, wall-type anti-collision guardrails are widely used in the form of highway anti-collision barriers. The existing wall-type anti-collision barriers can protect vehicles, but the wall-type anti-collision barriers adopt reinforced concrete structure, the rigidity is too large, and the energy dissipation effect after the collision of the car is poor. Personnel are seriously injured.

Utility model content

In view of this, the purpose of the present utility model is to provide a high energy dissipation anti-collision device, so as to improve the energy dissipation effect of the anti-collision device, and further reduce the damage of traffic accidents to vehicles and passengers.

The utility model solves the above problems through the following technical means: a high energy dissipation anti-collision device, including a cement body, a buffer body is arranged inside the body, and the buffer body includes a rubber shell and a plurality of rubber shells arranged in the rubber shell. The energy dissipating body, the energy dissipating body includes a first spring, a corrugated rubber tube and a second spring connected in sequence.

Further, the surface of the rubber shell is provided with a plurality of grooves.

Further, the helical directions of the first spring and the second spring are opposite.

Beneficial effects of the utility model: the high energy dissipation anti-collision device of the utility model includes a cement body, and a buffer body is arranged inside the body, and the buffer body includes a rubber shell and a plurality of energy dissipation devices arranged in the rubber shell The energy dissipation body includes a first spring, a corrugated rubber tube and a second spring connected in sequence. The high energy dissipation anti-collision device of this structure reduces the stiffness of the anti-collision device, improves the energy dissipation effect of the anti-collision device, and can buffer the car that is out of control, such as rollover or collision, and avoids the impact of rigid collision on the car itself. , People inside the car and people or things outside the car cause damage.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Fig. 1 is the structural representation of the utility model.

detailed description

The utility model will be described in detail below in conjunction with the accompanying drawings, as shown in Figure 1: a high energy dissipation anti-collision device, including a cement body 1, a buffer body is provided inside the body, and the buffer body includes a rubber shell 2 And a plurality of energy dissipating bodies arranged in the rubber shell, the energy dissipating body includes the first spring 3, the corrugated rubber tube 4 and the second spring 5 connected in sequence, when the impact occurs, the first spring and the second spring can Realize nested or partially overlapping structures. When the vehicle runs out of control and crashes into the anti-collision device, the vehicle is in contact with the buffer body. On the one hand, the rubber shell has a good energy absorption effect; on the other hand, the first spring, the corrugated rubber tube and the second spring all have a good At the same time, when the impact occurs, with the help of the deformation of the rubber bellows, the first spring and the second spring are socketed or partially overlapped, which can change the overall elastic coefficient of the energy dissipation body and further improve the energy dissipation body. energy-absorbing effect. To sum up, the high energy dissipation anti-collision device of this structure reduces the stiffness of the anti-collision device, improves the energy dissipation effect of the anti-collision device, and can buffer the car that is out of control, such as rollover or collision, and avoids Rigid collisions cause damage to the car itself, people inside the car, and people or objects outside the car.

As a further improvement of the above technical solution, a plurality of grooves 6 are provided on the surface of the rubber shell. The groove has the function of absorbing and releasing the impact energy.

As a further improvement of the above technical solution, the helical directions of the first spring and the second spring are opposite, so as to improve the uniformity of absorbing impact energy and further enhance the energy absorbing effect.

Finally, it is noted that the above embodiments are only used to illustrate the technical solutions of the present utility model without limitation. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the utility model can be Modifications or equivalent replacements of the technical solutions without departing from the spirit and scope of the technical solutions of the utility model shall be covered by the claims of the utility model.
