BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inrush prevention vehicle for protecting a worker from an inrush accident of a vehicle at a road construction site, and more specifically, to improve an inrush prevention function,
The present invention relates to an inrush prevention vehicle having excellent mobility such as installation, removal, and movement.

[0002]

2. Description of the Related Art In order to carry out road construction without completely blocking the road, the road construction area is limited to one of left and right oncoming lanes, and the other is made to pass by alternately. When performing such road construction, safety equipment such as barricades for preventing the entry of vehicles is installed before and after the construction site on the lane for road construction to protect the safety of workers. But,
Since it is very troublesome to transport such safety equipment to the construction site, and to remove, move, and re-install it every time the construction position changes at the construction site, it may cause a significant decrease in work efficiency. Was becoming.

In order to improve the work efficiency of transporting such safety equipment to the construction site, and removal, movement, and re-laying at the construction site, a buffer box as safety equipment is previously attached to the rear part of the moving vehicle. A rush-prevention vehicle has been put to practical use, which is mounted upright and transported to the construction site as it is, and at the same time, it is laid down and used. However, since the width of the buffer box mounted on the vehicle cannot be wider than the vehicle width due to the regulation of the safety standards for road transport vehicles, the buffer box must be installed to improve the inrush prevention function at the construction site. Even if I tried to increase the range of the situation, I couldn't do it.

SUMMARY OF THE INVENTION It is an object of the present invention to increase the width of a buffer box to a width greater than the vehicle width within the regulation of the safety standards of road transportation vehicles while ensuring the mobility of the vehicle for inrush prevention. An object of the present invention is to provide a vehicle for inrush prevention that enables the inrush prevention function to be further improved.

[0005]

A vehicle for rush prevention according to the present invention is provided with a pair of left and right shock absorbing boxes attached to a cargo bed, and the pair of shock absorbing boxes are placed upright in front of and behind the cargo bed and a position behind the cargo bed. The present invention is characterized in that it is movable and can be laid down in the left-right direction at a position behind the loading platform, and the total width of the pair of buffer boxes after the laying down is made larger than the vehicle width.

[0006] As described above, the buffer box which is larger than the vehicle width is provided. However, the buffer box is stored as a pair of buffer boxes in a folded state during movement so that it can be transported without violating the safety standard of the road transportation vehicle. To enable.
In addition, the pair of shock-absorbing boxes are laid down in the left-right direction at the rear of the bed during use to be used in a state in which the cushion boxes are expanded more than the vehicle width, whereby the rush prevention function can be further improved.

The structure of the present invention will be described below with reference to the accompanying drawings. In the figure, a vehicle 1 for rush prevention is equipped with a signal display device 2 for displaying traffic information related to road construction at the rear of a driver's seat, and a collision energy absorption device 4 on a cargo bed 3. The collision energy absorbing device 4 is configured as follows. That is, the storage device 5 is installed between a pair of rails 6 provided on both edges of the luggage carrier 3, and the rails 6 are driven by the engine output or the like as a drive source.
Is slidable on the cargo bed 3 in the vehicle length direction. The rail 6 is provided with a spiral shaft (not shown) in the length direction, and the storage device 5 is moved forward and backward by transmitting engine output or the like from the shaft 7 to the spiral shaft for rotational driving. A pair of support arms 8 which can be opened and closed in a V shape from a vertical state to a horizontal state by expansion and contraction of a hydraulic cylinder are installed at the rear part of the storage machine 5, and a buffer box 9 is attached to each of the pair of support arms 8. Has been. A tail lamp 10 may be provided on the rear end surface of the buffer box 9 to prevent a rush accident, or a striped pattern may be applied.

Each buffer box 9 may be one that absorbs impact energy by being deformed by an external force,
It may be made of a shock absorbing material such as a hollow aluminum material or urethane which is finely divided, and these may be combined. The width of each buffer box 9 in the vehicle length direction (see FIG. 4) is set so that the total width when the pair of buffer boxes 9 is horizontally arranged is at least wider than the width of the vehicle 1. ,
The length and thickness are not particularly limited and can be set appropriately. For example, when a pair of closely-spaced hollow aluminum buffer boxes 9 (total width 3685 mm) having a width of 1830 mm, a length of 2070 mm and a thickness of 570 mm are attached to a vehicle width of 2370 mm, the speed is 60 km. Even if a passenger car or a light-duty truck (gross weight of 2 tons or less) traveling at / h rushes in, the impact energy can be sufficiently absorbed.

On the other hand, protective fences 11 are provided on both sides of the rush prevention vehicle 1, respectively. The protective fence 11 is supported by three support arms 12 that are expandable and contractible by a hydraulic pump or the like, and can be expanded in the vehicle width direction by expanding and contracting the support arms 12. It is preferable to control the expansion operation of the protective fence 11 independently on the left and right sides, and by performing the independent control in this way, only the side that requires protection can be expanded according to the construction lane.

A vehicle 1 for preventing inrush constructed as described above.
At the time of movement, the pair of buffer boxes 9 are stored in the luggage carrier 3 in a state of being folded parallel to each other as shown in FIG. Therefore, even if the buffer box 9 is made large, the collision energy absorbing device 4 can be mounted without causing the vehicle width or vehicle length to violate the safety standards of the road transportation vehicle.

On the other hand, at the time of work, the rush prevention vehicle 1 is stopped in front of the road construction site, and the storage unit 5 is slid to the rear side of the vehicle as shown in FIG.
Is projected to the rear of the vehicle and the protective fence 11 is expanded in the vehicle width direction. Thereafter, as shown in FIGS. 3 and 4, the pair of support arms 8 are opened to the horizontal state, whereby the pair of buffer boxes 9 are laid down in the left-right direction and horizontally supported in a state in which the cushion boxes 9 are expanded more than the vehicle width. In this case, the protective fence 11 preferably extends to the end of the buffer box 9 protruding from the vehicle width.

This allows the pair of buffer boxes 9 to be used during work.
Since the road width wider than the vehicle width can be closed by the total width of, and the pair of buffer boxes 9 can be set to a size capable of sufficiently absorbing the impact energy as described above,
It is possible to reliably prevent a rush accident even on a road wider than the vehicle width. Further, the installation and removal as described above can be easily performed, and since the collision energy absorbing device 4 is mounted on the rush prevention vehicle 1, it has excellent mobility in installation, removal and movement.

Further, by extending the protective fence 11 to the end of the buffer box 9 protruding from the vehicle width, the side surface of the rush prevention vehicle 1 can be protected against a rush vehicle from the side, and The inrush vehicle can be safely guided to the driving lane. The vehicle for rush prevention of the present invention protects a worker from a rush accident at a road construction site, and as shown in FIG. 5, the buffer box 9 is deformed by an external force at the time of vehicle rush to absorb the collision energy. As a result, it is possible to ensure the safety of the entry vehicle. In this case, the shock absorbing box 9 is significantly damaged, but other members are hardly damaged, so that the shock absorbing device 4 can be repeatedly used by replacing only the shock absorbing box 9.

[0014]

As described above, according to the present invention, a pair of left and right shock absorbing boxes are attached to a cargo bed, and the pair of shock absorbing boxes can be moved back and forth between the cargo bed and a position behind the cargo bed in an upright state, While being able to fall in the left-right direction at a position behind the loading platform, and making the total width of the pair of buffer boxes after this fall larger than the vehicle width, while ensuring the maneuverability of the rush prevention vehicle. The width of the buffer box can be increased more than the vehicle width within the regulation of the safety standard of the road transportation vehicle, and the inrush prevention function can be further improved.

Further, a protective fence that can be expanded in the vehicle width direction is provided on the side of the vehicle, and this protective fence is expanded to the end of the buffer box that protrudes from the vehicle width during work, so that the side surface of the vehicle for preventing entry is expanded. The vehicle can be protected and the entry vehicle can be safely guided to the driving lane.
