UA142760U - MEANS TO PREVENT UNAUTHORIZED PASSAGE OF MOTOR VEHICLES - Google Patents

Abstract

The means for preventing the unauthorized passage of motor vehicles includes a plate for the passage of vehicles, entrance (exit) ramps, fixed stiffeners connected to the plate for the passage of vehicles, with a distance between them not less than the width of the wheel, parallel to the entrance ramparts and conical on the side of the exit ramparts. Fixed stiffeners are connected to movable stiffeners along the entire length from the entrance to the exit ramp by means of clamps.

Description

The useful model belongs to the field of means of combating manifestations of terrorism, namely to the means of preventing the penetration of cars, including minefields driven by terrorists, into the protected territory, and specifically to the means of preventing the unauthorized passage of motor vehicles, which are designed to forcibly stop motor vehicles , and can be used in the organization of mobile checkpoints and protection of objects.

Known devices for preventing unauthorized passage of cars. For example, there are known designs of mechanical barriers and barriers for forced stopping of vehicles in the form of racks that are installed below the ground level and that have the ability to extend above the ground surface with the help of a pneumatic drive (Patent 05 4576508 A, EOTE 13/04,

EOTE 13/00, 1986), in the form of "hedgehogs" with a pneumatic and electric drive (Patent 5 1799452, ГА1Н 11/08, EOTE 13/00, 1993), in the form of an anti-ramming barrier (Patent 05 5997211 A,

EOTE 13/06, EOTE 13/12, EOTE 13/00, 1999).

The disadvantage of these structures to prevent unauthorized passage of cars is that their construction requires time-consuming earth (concrete) works, so they can be used to protect stationary objects and cannot be used for the operational organization of mobile checkpoints and checkpoints on roads and in populated areas.

A known anti-ramming barrier, which consists of a beam, one end of which is hinged on one support with the ability to rotate the beam in the horizontal plane, and the other is fixed on the second support using a mechanical locking device (Patent VO 2224840

C1 (EOTE 13/10, 2004)).

The disadvantage of this design for preventing unauthorized vehicle passage is that its construction requires time-consuming earth (concrete) works, therefore it can be used to protect stationary objects and cannot be used for the operational organization of mobile checkpoints and checkpoints on roads and in populated areas.

A known anti-ramming barrier, which consists of a protective barrier in the form of a cable, which is stretched across the roadway between two supports located on both sides

From the driveway, and fixed to the racks with the help of fasteners that hold two platforms, fixed on the racks with hinges, with the possibility of overturning, on which two welded metal obstacles ("hedgehogs") are freely installed (Patent NO 2333308 C1 BOTE 13/10 , 20081.

The disadvantage of this design for preventing unauthorized vehicle passage is that its construction requires time-consuming earth (concrete) works, therefore it can be used to protect stationary objects and cannot be used for the operational organization of mobile checkpoints and checkpoints on roads and in populated areas.

The closest analogue is a device for preventing the unauthorized passage of motor vehicles, which consists of a plate for the passage of motor vehicles, an entrance (exit) apparatus, external stiffeners connected to a plate for the passage of motor vehicles, with a distance between them not less than the width of a car wheel , parallel on the side of the entrance apparatus and cone-shaped external stiffeners on the side of the exit apparatus. In the case of an unauthorized attempt to enter the prohibited territory, the car drives into the entry ramp, drives along the outer parallel stiffeners and hits the cone-shaped external stiffeners on the side of the exit ramp with its wheels, when the car wheels interact with the cone-shaped external stiffeners (due to frictional forces between the wheels of the car and the cone-shaped outer ribs) the car stops. (Patent OA 133779, BAS 11/08, EOTE 13/12, 04/25/2019

The disadvantage of this design for preventing unauthorized traffic is that it is structurally designed for one size of wheels and, accordingly, one class of car and is not universal. Yes, external parallel and cone-shaped stiffeners are permanently fixed to the plate (welding or bolting) and cannot change their height by sliding. That is, the design for preventing the unauthorized passage of passenger cars cannot be used to prevent the unauthorized passage of, for example, trucks. Therefore, for the organization of mobile checkpoints, it is necessary to have several standard sizes of structures, and this will create certain problems of both a technical and financial nature.

The useful model is based on the task of creating a means to prevent 60 unauthorized passage of motor vehicles, the design of which allows for prompt and reliable unauthorized passage of vehicles of various classes into prohibited territory when organizing mobile roadblocks, checkpoints on roads and in populated areas, when conducting mass shares

The task is solved due to the fact that in the design of the means for preventing unauthorized passage of motor vehicles, which contains a plate for the passage of motor vehicles, entry (exit) devices, fixed external stiffeners connected to the plate for the passage of motor vehicles, with a distance between they are not less than the width of a car wheel, parallel on the side of the entrance apparatus and cone-shaped stiffeners on the side of the exit apparatus, according to the useful model, additionally introduced movable stiffeners connected to fixed stiffeners along the entire length from the entrance to the exit appliances with the help of fasteners.

In Fig. 1 shows a scheme of means for preventing unauthorized passage of motor vehicles, top view.

In Fig. 2 shows a diagram of a device for preventing unauthorized passage of motor vehicles, side view.

In Fig. 3 shows a diagram of a device for preventing unauthorized passage of motor vehicles, general view.

The proposed means for preventing unauthorized traffic traffic includes: a plate for the passage of motor vehicles 1, fixed stiffeners 2, entry (exit) devices 3, movable stiffeners 4, fasteners 5 connecting movable and fixed stiffeners,

In the proposed means for preventing unauthorized passage of motor vehicles, all the components are made as known designs, for example, made of metal.

The work of the proposed tool is as follows:

When preparing for mass actions in populated areas, organization of mobile roadblocks, checkpoints on roads, an analysis of the operational situation is carried out, vehicles at the disposal of offenders are determined. A means to prevent unauthorized passage of motor vehicles into the prohibited territory is brought and installed in the required place. Mutual location of the outer movable ribs

From the rigidity of the correspondingly fixed external stiffeners in the vertical plane, it is established in accordance with the technique that can carry out unauthorized passage into the prohibited territory.

When an unauthorized person tries to enter the prohibited territory, the car drives into the entry ramp, drives along the parallel stiffeners and falls with its wheels into the cone-shaped stiffeners on the side of the exit ramp, when the car wheels interact with the cone-shaped stiffeners (due to the frictional forces between the wheels of the car and conical ribs) the car stops. In the event of a change in the operational situation, the device for preventing the unauthorized passage of motor vehicles can be reconfigured for the class of cars that the offenders have by raising or lowering the parallel and cone-shaped stiffeners relative to the plate for the passage of motor vehicles and fixing them at the required height.

The technical result that can be obtained in the execution of a useful model consists in increasing the efficiency of installation of a means to prevent the unauthorized passage of motor vehicles and the reliability of stopping the unauthorized passage of cars of various classes into the prohibited territory due to the forced deformation of tires and metal parts of the car wheels between the cone-shaped ribs, and corresponding loss of mobility by car.
