Abstract

FIELD: transport.

SUBSTANCE: invention is designed to control passage of motor transport into the territory of special guarded objects, to prohibit unauthorised passage thereto, and to halt the said transport aiming at breaking through towards the guarded objects. The proposed simple-design and operation anti-ram barrier incorporates two supports spaced apart by the distance not smaller than the motor transport width and a cable barrier crossing the passage and attached to the said supports. The proposed structure comprises also the pillars mounted behind the said supports, along the motor transport motion, with the capsizing platforms hinged to the said pillars and accommodating a "hedgehog"-type metal structures falling on to roadway with the said platforms capsized. The cable arranged across the roadway is linked with retainers preventing the platform capsizing, the distance between the supports and pillars is selected subject to the motor transport ramming speed. The cable can furnished with connectors arranged on both supports and laid in a metal pipe at the section between the support and pillar.

EFFECT: reliable blocking of passage, ease of manufacture, installation and operation.

Description

The present invention relates to means of forced stopping of transport, namely to cable devices of forced stopping of transport, and can be used to control the passage of vehicles into the territory of especially important protected objects.

Known rotary road fence (Pat. France No. 27777301 from 04/14/1998, publ. 10/15/1999 g, IPC E01F 13/04), providing the possibility of selective permission or prohibition of the car from reaching its destination or leaving a street or road having a box, designed to be placed in the ground or pavement, which has a cavity with an opening for access to this cavity and a barrier element that retracts into this cavity, which rotates in the box around the axis of rotation between a position in which at least the first part is blocked of the element protrudes above the box, thus obstructing the passage of cars, and the second part overlaps the opening of the box, as well as the inoperative position, in which the element is completely removed into the box, while blocking its opening.

The disadvantages of this design are:

- the complexity in the manufacture and installation;

- high price;

- requires laborious maintenance during operation in the winter period of time;

- does not allow mechanical cleaning of the passage from snow;

- does not withstand the necessary shock load of a moving vehicle, and therefore, will not be able to reliably block access to the protected object.

The closest in terms of function and set parameters is the known anti-ram barrier (Pat. RF No. 2224840 of 07/12/2002, publ. 02/27/2004, IPC E01F 13/10) containing a beam, one end of which is pivotally mounted on one support with the possibility of it turning in the horizontal plane, and the other is mounted on another support using a mechanical locking device. The beam is welded from two channels and inside the beam pre-tensioned steel cables are mounted and fixed at the ends, and steel spikes are welded on the outside of the beam, which increase its protective properties. At the cantilever end of the beam, an end plate is welded to prevent the end of the beam from breaking out of the locking device when it is deflected.

This device is selected as a prototype.

The known device has several disadvantages:

- the great complexity of manufacturing and installation;

- high price;

- long recovery after operation;

- requires a lot of effort to service when passing transport;

- the device requires qualified maintenance.

The objective of the invention is the development of a simple design, reliable in operation and easy to manage and maintain, under any climatic conditions, cheap to manufacture and install an anti-ram device.

The technical result of the use of the claimed device is the reliable closure of the passage to the guarded object and the stop of vehicles moving to break through to the guarded object with different speeds, ease of manufacture, installation and operation.

The technical result is achieved due to the fact that the anti-ram barrier, containing two supports at a distance from each other no less than the vehicle width and a cable barrier mounted across the passage onto the supports, is equipped with uprights installed behind the supports along the vehicle, on them platforms with the possibility of overturning are pivotally fixed, metal structures in the form of "hedgehogs" falling on the roadway when the platforms overturn are freely placed on the platforms, a cable installed across so, it is in communication with retainers, the holding platform from tipping over, and the distance between the supports and struts is chosen depending on the target vehicle speed during ramming.

The barrier cable may have connectors on both supports for organizing the passage of the vehicle.

The cable can be enclosed in a pipe in the areas between the supports and uprights.

For authorized passage of vehicles, the barrier cable may be opened at one of the supports and removed from the roadway.

After passing vehicles, the barrier cable returns to its place.

The racks installed behind the supports in the direction of transport with platforms pivotally mounted on them are simple elements that do not require large expenses for manufacturing and installation. The articulated mounting of the platforms on the racks fixed by the clamps allows to reliably overturn the "hedgehogs" placed freely on the platforms, as these elements are reliable in operation and do not require qualified personnel when servicing. A cable covering the passageway, having a connection with the latches, pulls the latches when the vehicle is exposed to it, and the platforms tilt over, and the "hedgehogs" reliably block the unauthorized access of the vehicle to the protected area. The choice of the distance between the supports and racks allows you to set them depending on a given speed of transport, i.e. the anti-ram barrier can easily be re-adjusted to any vehicle characteristic.

Since the time of falling of mechanical barriers after pulling out the clamps is constant, an increase in the distance between racks with barriers and supports increases the likelihood of a reliable stop of a car moving at a higher speed. The connectors on both supports make it easy to service the vehicle pass, without the significant effort required in the prototype. The cable enclosure in the pipe in the area between the supports and uprights prevents from accidental operation of the anti-ram barrier.

The pulling force of the latches is selected in such a way that a person cannot force the device to operate by his own effort. This is a significant advantage of the claimed device.

The inventive combination of features, low cost and ease of manufacture of structural elements that make up the inventive means of forcibly stopping transport, ease of removal of the cable to pass transport allows you to achieve the above technical result.

Figure 1 presents a General view of the inventive device.

Figure 2 presents the operation diagram of the anti-ram barrier when trying to unauthorized passage, where:

1. cable;

2. support;

3.stand;

4. platform;

5. a metal barrier in the form of "hedgehogs";

6. clamp;

7. carabiner;

8. vehicle;

9. hinges.

Management of the passage of vehicles is as follows.

A rope-shaped barrier (1) is pulled across the car passage between two supports (2) located on both sides of the car passage and secured to the struts (3) using the clips (6) that hold the two platforms (4) in the cocked position mounted on racks by means of hinges (9), with the possibility of tipping over, onto which two welded metal barriers (hedgehogs) (5) are freely mounted. The cable opens at one of the supports (2) with a carbine (7) and is pulled out of the carriageway, freeing the car passage for the passage of vehicles.

The device operates as follows:

The cable (1) is installed across the passage and mounted on supports (2). When trying to ram, the vehicle (8) moves the cable in the direction of travel.

Under the action of the tensioned cable, the clips (6) are pulled out holding the platforms (4) with metal barriers (5). Platforms under their own weight and the weight of metal barriers installed on it, overturn and metal barriers (hedgehogs) slide off the platforms, and move to the carriageway, stopping in the path of movement of the vehicle (car).

As an example of a specific design, a prototype was designed to stop a vehicle (car) moving at a speed of up to 30 km / h, where the diameter of the power support pipes is 200 mm, the cable thickness is 10 mm in diameter, and the total cable length is 15 m. metal welded barriers were made "hedgehogs", welded from sections of channel No. 14, the length of each segment is 1500 mm. Welded metal structures with tipping platforms mounted on them, covered with steel sheets, are used as racks, the height of the center of the "hedgehogs" above the ground is 1,500 mm. The cable in the area from the clamps to the supports is hidden inside the fence pipe. As pins, metal pins are used, specially fixed at the ends of the cable.

Tests were carried out that confirmed the objectivity of the meeting of the car with metal barriers. The manufactured prototype of the claimed device during the test showed good results and confirmed a new technical result.
