Description

The utility model relates to controlled means of protection against a ram attack delivered using vehicles by forcibly stopping the latter due to the repayment of the kinetic energy of movement with the help of physical obstacles, and is intended for the prompt erection of barriers on roads, including blocking a possible breakthrough of vehicles in cases of a threat of a terrorist attack on protected areas, buildings and structures for military and civilian purposes, as well as objects and places with a mass stay of people.

At present, most terrorist acts aimed at destroying military and civilian buildings and structures are carried out by means of vehicles filled with explosives entering the territory of these facilities, followed by their detonation. At the same time, terrorist attacks are increasingly aimed at objects and places with a massive presence of people.

An analysis of the vulnerability of such objects shows that the greatest danger in a ram breakthrough on an object is the use of heavy vehicles. The most likely means for a breakthrough can be trucks that develop speeds of over 80 km / h, weighing from 8 to 20 tons, having a clearance of about 260 - 400 mm, for example, the brands Ural, MAZ, KamAZ, KrAZ ". They are able to overcome anti-ram devices that are not strong enough and reliable from an engineering point of view, blocking the road and deliver a deadly load directly to the object, close to buildings, structures or crowds of people (S.Yu. security, No. 2, 2017, pp. 36-37).

Blocking the breakthrough of vehicles in such cases is usually solved with the help of anti-ram controlled devices (GOST R 57362-2016 "Controlled anti-ram devices. Classification. Terms and definitions"), which are divided into:

- barriers moved in vertical and horizontal planes, rising, rotary and retractable beams;

- vertically retractable poles and columns;

- retractable and vertically swivel platforms of the "elevating roadbed" type;

- cable block tension systems.

All of the above obstacles, as a rule, are stationary structures and provide protection for specific objects in standard countermeasure conditions.

In the event of unforeseen circumstances of the threat of a terrorist act by ramming anywhere, for example, in the event of a mass gathering of people on the streets, roads and squares during socio-political and festive events, rallies, demonstrations, etc., rapidly deployable mobile anti-ram barriers, which are mobile rigid metal structures, usually of a modular assembly, which must withstand a directed impact load and completely absorb the kinetic energy of the vehicle. They are characterized by fast delivery, assembly and installation, and the number of their modules is determined by the perimeter of the protected area and the width of the passage.

From the prior art, a fencing module and a fencing based on it are known (RU 2561129 C1, publ. 20.08.2015, bull. No. 23). The fencing module is a spatially curved wedge-shaped body. The rigidity of the body is provided by a jumper connecting the walls of the body to each other in the upper part. The lower parts of the walls are equipped with flanges directed outward, which act as supports. A plurality of single modules connected to each other by articulated rods and deployed in a line form a fence. Being deployed linearly, the walls of the module housing are structurally overlapped. At the same time, they are additionally connected to each other with fasteners, ensuring the rigidity of the fence as a whole.

The practice of erecting such a modular fence is very laborious. First, the modules connected by articulated rods are installed one into the other, forming an assembled fence from a package of folded modules, then the folded fence is placed on the vehicle platform and turned outwards with flanges in the direction of movement at an angle of not more than 90 degrees, and then unfolded linearly by means of forced dumping from the platform to the earth's surface during the movement of the vehicle. In this case, distortions of the modules relative to each other may occur, causing instability of the deployed fence as a whole, which can be eliminated manually.

It is also known a means of forced stopping of motor vehicles (RU 87007 U1, publ. 20.09.2009, bull. No. 26), which is a collapsible barrier containing many identical modules in the form of crossed steel profile beams. The beams are crosswise connected in pairs by means of locking devices, in the form of grooves mating with each other, made on adjacent profile shelves, with a depth of not more than half the width of the shelves.

Cross-shaped barrage modules are coaxially mounted on a horizontal carrier rod with a constant pitch and fixed from axial movement by separating tubes.

A support is rigidly attached to the lower part of each beam, for example, welded, the upper part of which is equipped with a spike to damage the wheels of vehicles, and the lower part has holes for the installation of anchor crutches to ensure the fixation of the barrier to the roadway. The upper part of the beams is made pointed and directed towards the moving vehicle in order to destroy the elements of its engine, cooling system, etc.

Known means for forced stopping of motor vehicles can be taken as the closest analogue of the claimed utility model (prototype) by the maximum number of essential features identical with it.

The disadvantage of the prototype is that when ramming the strength and stability of the known design as a whole leaves much to be desired. Although each individual module is cross-connected to ensure its rigidity, when assembled they are all mounted on a rather long rod in the only place - in the center of each cross beam. Without additional transverse rigid connections between the supports, or directly between the beams, the known barrier device may not withstand the powerful frontal shock load of the vehicle.

In the places where the beams are connected to the rod, the latter can be damaged (bent, twisted, etc.), and in general, the entire barrier will lose stability in the direction of the vehicle, and therefore the instant stop of the latter will not be achieved. The vehicle moving by inertia will overcome some more distance together with the damaged barrier towards the protected object, which is fraught with unpredictable consequences.

In addition, the well-known barrage means is devoid of mobility, its area of action is specific, and its working position is unchanged, therefore it does not have the ability to quickly move to a new location in case of unforeseen circumstances, the threat of a terrorist act with a ram strike anywhere, for example, in a mass congestion of people.

The problem solved by the claimed utility model is to create a new design of a mobile, collapsible, anti-ram barrier of a modular type, compact in storage and transportation, minimizing the time for its installation and dismantling, with the possibility of its prompt movement and installation in a new location. In this case, the mobile anti-ram device must be activated so quickly and work so effectively as to instantly disable the undercarriage of a vehicle with a carrying capacity of up to 20 tons and immobilize it completely.

With the practical application of the claimed utility model, the following technical result is achieved: the effectiveness of the anti-ram barrier in terms of increasing its stability during a ram impact and the reliability of stopping a moving vehicle is ensured; simplifies the assembly-dismantling procedure and minimizes the time of its implementation; provides a high degree of mobility when moving to a new location.

The task set can be implemented, and its technical result can be achieved through a specific technical solution of the utility model, characterized by the fact that:

- its design includes a plurality of anti-ram modules connected linearly with a constant step into a single whole with the help of crossed couplers, each of which is made in the form of a rack, articulated with the base, equipped with rear and front support wheels (which will allow blocking roads of any width);

- the rack of each anti-ram module is a frame structure made of two sidewalls rigidly connected to each other, and the base is installed between the sidewalls of the racks (which will ensure sufficient rigidity of the barrier structure and allow it to withstand the power of the frontal shock load of the vehicle);

- crossed ties are mounted between the posts in the upper part of the module and between the bases in the lower part of the module and are located respectively in the vertical and horizontal planes in pairs and symmetrically (which will provide additional rigidity of the barrier as a whole and allow you to quickly immobilize the vehicle);

- each anti-ram module is made collapsible, with the possibility of rotation of the rack relative to the base from the transport horizontal position to the working vertical position, followed by fixation of both in the place of their articulation (which turns the module into a transformer, compact during storage and small-sized during transportation);

- and is equipped with a removable thrust canine in the form of a pair of symmetrically arranged plates of the same configuration, the back part of which is made in the form of a figured shank containing two points - lower and upper (providing reliable adhesion of the canine to the road surface during ramming, which will increase the stability of the barrier and ensure its braking on the roadway);

- each rear support wheel is located between a pair of adjacent posts in the lower part of the barrier and is mounted on a removable tubular axle, fixed at the ends in the side walls of the posts with the possibility of linearly connecting all the wheels together into a prefabricated chassis (which will ensure high mobility in any direction of movement of the barrier and under any angle to the blocked road);

- at the same time, on both sides of the peripheral part of the plurality of support wheels connected in the chassis, handles of the same configuration are symmetrically attached to the end tubular axles, which together with the assembled tubular axles serve as a lever for transferring the chassis from the transport position to the working position and vice versa (which will allow you to quickly transfer the barrier from the mobile state to combat and back);

- each front support wheel is mounted on the periphery of the corresponding base on an axle fixed in lugs rigidly connected to the side walls of the base, and the upper surface of each base near the front support wheel is equipped with a tire cutter made in the form of a flat pointed wedge, mounted with the possibility of rotation from the working position to a safe one, for example, during the installation and dismantling of the barrier (which will allow you to instantly disable the chassis of the vehicle and damage the components and assemblies of the transmission and engine);

- each anti-ram module is equipped with a transport belt for ease of carrying it in the folded position, fixed on cylindrical inserts mounted on the rack and base and made of elastic material, for example, polyester tape (which will ensure proper handling of the barrier when transporting it to the place of deployment );

- the connection of all its main components and parts with each other during the mounting-dismantling process was carried out manually, without the use of mounting tools, using unified quick-release elements, for example, axles with a spring cotter pin or directly with pipe cotter pins (which simplifies the procedure for mounting and dismantling the barrier and minimizes execution time).

A comparative analysis of the essential features of the claimed utility model in comparison with its analogues shows that from the prior art at the date of filing the application is not known and does not follow explicitly for the "average specialist" in this field of technology device of the same purpose as the claimed utility model, in which the entire set of essential features given in the independent claim and disclosed in the description would be applied.

At the same time, the proposed set of essential features is not obvious and ensures the emergence of new properties for the claimed utility model, which make it possible to implement the task, which means that it meets the "novelty" criterion.

In general, the design of the claimed utility model is manufacturable, so its production does not present technical difficulties, which indicates that the utility model also meets the criterion of "industrial applicability".

The mobile anti-ram barrier "Interceptor 20" (Fig. 1, 2, 3, 4) is a rigid metal structure assembled from a plurality of anti-ram modules 1, each of which is made in the form of a rack 2, articulated with the base 3, which are connected to each other linearly with a constant step into a single whole with the help of crisscross couplers 4. Rack 2 is a frame structure of two sidewalls made of a metal profile, for example, a corner or a channel, or a curved profile, rigidly connected together, and base 3, made of the same profile , installed between the sidewalls of the rack 2 (Fig. 6). At the point of articulation, the rack 2 and the base 3 are connected by a unified quick-detachable element 7 (Fig. 2), for example, an axle with a spring cotter pin, forming a swivel joint.

Each anti-ram module 1, as a single modular element, has a folding structure (Fig. 5). It is equipped with a transport belt 15 (Fig. 6) for ease of carrying it in the folded position, fixed on cylindrical inserts 16 mounted on a rack 2 and a base 3 made of an elastic material, for example, a polyester tape. In the folded (transport) state, module 1 is quite compact, so it does not take up much space when stored in a warehouse and is convenient for transportation by road.

After assembly, the rigidity of the anti-ram barrier structure will be ensured by the presence of a plurality of modules connected by crossed ties 4, mounted both between posts 2 in the upper part of the module, and between bases 3 in its lower part, and located respectively in the vertical and horizontal planes in pairs and symmetrically (Fig. one).

The mobility of the anti-ram barrier is ensured by a system of rear 5 and front 6 support wheels.

Each of the rear 5 support wheels is located between a pair of adjacent posts 2 in the lower part of the barrier and is mounted on a removable tubular axle 9 (Fig. 8, 10). The rear support wheels 5 during the installation of the barrier are installed linearly with the possibility of connecting all together in a prefabricated chassis using tubular axles 9 by means of unified quick-release connecting elements 10, for example, pipe cotter pins.

On both sides of the peripheral part of the plurality of support wheels 5 connected in the chassis, handles 11 of the same configuration (Fig. 11, 3) are symmetrically attached to the end tubular axles 9, which together with the tubular axles 9 in the assembly serve as a lever for transferring the chassis from the transport position to the working position, providing thus the combat position of the anti-ram barrier.

Each front support wheel 6 (Fig. 12) is mounted on the periphery of the corresponding base 3 on the axis 12, fixed in the lugs 13, rigidly connected to the side walls of the base 3. The upper surface of each base 3 near the front support wheel 6 is equipped with a tire cutter 14 (Fig. 13 , 14) designed to damage the pneumatic tires, thus providing an additional stopping effect on the vehicle. Tire cutter 14 is made in the form of a flat pointed wedge, mounted with the possibility of rotation from a working, combat position to a safe, folded one. Anti-ram barrier with tire cutters 14 in a folded, safe position is used in situations with a large crowd of people in the area of its installation, in order to eliminate the risk of injury to people on the surface of the tire cutters.

The design of the tire cutter 14 excludes its accidental transfer from a safe position to a combat one, since in a safe position its wedge-shaped pointed part is securely fixed by a unified removable fastener in the form of an axis with a spring cotter pin (not shown in the figures). To transfer the tire cutter to the combat position, it is necessary to unlock it by removing the axle, turn the wedge-shaped part of the tire cutter with the tip up and install the axle again, fixing the axle with a spring cotter pin.

Each module 1 at the junction of the rack 2 with the base 3 contains a removable thrust canine 8 mounted using unified quick-release elements 7 (Fig. 8, 9). Removable thrust canine 8 is made in the form of a pair of symmetrically arranged plates of the same configuration, made of high-carbon, wear-resistant steel, the back of which is made in the form of a figured shank containing two points - the lower "a" and the upper "b". The set of many persistent fangs 8 performs the function of the braking mechanism of the anti-ram barrier and provides the required stability of the barrier during a ram impact due to the deep penetration into the surface of the road surface of the tip "a" or "b". The lower tip "a" is triggered when the vehicle hits the anti-ram barrier at low speed, and the upper tip "b" is triggered when a collision occurs at high speed, when the anti-ram barrier overturns "on its back" from the impact.

Thanks to the fastening of the thrust canine 7 with unified quick-release fasteners, it can be easily replaced without the use of mounting tools in case of bending of the upper or lower tip due to the impact of the vehicle on the anti-ram barrier or in cases of blunting of the lower tip "a" caused by abrasive wear during operation.

All strength and dynamic characteristics of the above-described design of the mobile anti-ram barrier "Interceptor 20" are designed to counter vehicles with a carrying capacity of up to 20 tons.

The assembly of the mobile anti-ram barrier "Interceptor 20" and its subsequent operation are as follows.

In the folded state, according to the principle of transformers, packed in a special container in the form of portable bags, anti-ram modules are stored in a warehouse. In the event of threats of a different nature, they are promptly delivered by any type of transport to the place of deployment, where they are installed by two people.

When mounting the anti-ram barrier, the modules are deployed from the transport, horizontal position (Fig. 5) to the working, vertical position by turning the rack 2 relative to the base 3 (Fig. 6).

Perform it as follows. First you need to unlock the rack 2, temporarily connected for ease of transportation with the base 3 by disconnecting a unified quick-release element (not shown in the figures), for example, an axle with a spring pin. Next, the rack 2 is transferred to the working position, turning around the axis 7 (Fig. 2) and connect both in a new place with the previously removed axis, fixing it with the same spring pin. This procedure is carried out without the use of mounting tools, since the entire structure of the anti-ram module is assembled using unified quick-detachable connecting elements 7.

Then they begin to assemble the rear support wheels 5 all together in the chassis (Fig. 8) by installing the end part of one of the tubular axles 9 into the side walls of the racks 2 until it stops, starting from the extreme, and then, sequentially connecting the remaining axles to each other coaxially with pipe fixation pins 10.

Handles 11 are attached to the rear wheels 5 connected in the chassis (Fig. 11, 3), which are the lever for transferring the chassis from the transport position to the working position.

Next, you need to unlock the end part of the ties 4 (Fig. 6), temporarily fixed during transportation on the rack 2 and base 3, and then spread the free part of the ties to the sides (Fig. 7) and linearly assemble modules 1 with each other by crossing adjacent pairs of ties between the posts 2 and between the bases 3 (Fig. 3, 4) with their subsequent fastening again to the side surfaces of the latter with previously removed unified fasteners.

The assembled anti-ram barrier by turning the lever 11 (Fig. 3) is brought into a mobile state supported by wheels 5, 6 and manually transported to the place of permanent deployment. Due to the use of a linear system for connecting support wheels in the construction of the barrier, the anti-ram barrier has a high degree of mobility. It can be easily moved back and forth, left and right and quickly deployed on the spot, blocking the road or pedestrian crossing at any angle. After installation in a given place, the anti-ram barrier is quickly transferred from the mobile to the combat position by turning the lever 11, relying on the system of thrust canines 8.

When a vehicle hits an anti-ram barrier, the latter creates a reliable obstacle in the area of the running gear of a moving vehicle by: disengaging the wheels from the road, puncturing wheel pneumatic tires, damaging engine and transmission components and assemblies, as well as braking the barrier on the road surface.

The use of the claimed utility model will make it possible to effectively operate a new type of mobile devices for the erection of temporary barriers - mobile, foldable, increased stability, quickly deployed on roads of any width, safe for pedestrians, compact when transported by any mode of transport, operated in any natural and climatic conditions, at any time of the year and day.
