Description

The utility model relates to mechanical devices, in particular to anti-ram devices (barriers), designed to block the unauthorized passage of vehicles to special regime objects and protected areas.

A well-known automatic anti-ram barrier (Patent RU 115789, IPC: E01F 13/04, published May 10, 2012) containing a barrier hollow beam with power cables, one end of which is equipped with a counterweight and mounted on an axis mounted on the main rack with the possibility of rotation of the beam in vertical plane, and the free end is made with the possibility of fixing the beam in a horizontal position in the locking mechanism of the receiving rack. At the same time, the bases of both racks are rigidly fixed in the foundation blocks, and the lock mechanism body and the axis of the main rack are connected to additional power cables located vertically and rigidly fixed in the foundation blocks of the respective racks.

In this technical solution, the barrier beam is made with the possibility of movement in the vertical plane by rotation around the axis, which provides for the presence in its design of the counterweight necessary to hold the beam in the open position of the barrier. This significantly increases the intensity and weight of the device as a whole, while limiting the length of the specified beam to no more than six meters. The stiffness of the beam is also significantly reduced, and if its stiffness increases exponentially, the weight of the counterweight increases.

Known anti-ram barrier (Patent RU 2338830, IPC: E01F 13/10, published November 20, 2008) containing articulated and locking supports made of two metal pipes of different diameters with welded reinforcement in them, cast in concrete, and a beam welded from two channels in the form of a box mounted on supports with the possibility of its rotation in the horizontal plane. Inside the beam, pre-tensioned steel cables are mounted, fixed at the ends of the beam. The supports are made of different levels in height, on the hinge support the beam is fixed with a sleeve, two bearings and a locking clutch. On the castle support with the help of the tension unit of the cables and the locking device in the horizontal plane, the beam is held using a bracket.

The disadvantage of this technical solution is the low reliability of the device due to the high complexity of its design.

Closest to the claimed technical solution is the anti-ram barrier (Patent RU 2224840, IPC: E01F 13/10, published 02.27.2004) containing a beam, one end of which is pivotally mounted on one support (swivel support) with the possibility of its rotation in the horizontal plane, and the other is mounted on another support (fixing support) using a mechanical locking device. The beam is welded from two channels and inside the beam, pre-tensioned steel cables (ropes) are mounted and fixed at the ends of the beam, and steel spikes are welded outside the beam.

In this barrier, the cantilever end of the beam in a horizontal position is supported only by a rack with a wheel, which is not a reliable solution. In addition, the barrier has low strength, due to the fact that the beam has a rigid mount on only one support, as a result of which the design does not create a rigid opposing force that prevents unauthorized entry of vehicles.

The technical problem solved by the creation of this utility model is the low reliability, complexity and insufficient strength of the structures of close analogues, which, in turn, prevents the provision of high operational and protective properties.

The technical result of the claimed utility model is aimed at creating a simple in design and reliable in operation anti-ram device with enhanced strength and protective properties.

The technical result is achieved by the fact that the anti-ram device comprises a beam, one end of which is fixed on a rotary support with the possibility of its rotation in the horizontal plane, and the other is fixed on the first fixation support using a mechanical locking device. Inside the beam, a pre-tensioned steel ring rope is mounted and fixed at the ends of the beam. Moreover, it differs from the prototype in that the pivot bearing and the first fixing support are installed and rigidly fixed on reinforced concrete foundations dug into the ground. In this case, the pivot bearing is additionally fixed on the reinforced concrete base with scarves, and the end of the beam, mounted on the pivot bearing, is additionally fixed with a mechanical locking device to the second fixing support, which is mounted and rigidly fixed on the reinforced concrete base together with the pivot bearing. In addition, the beam is supported by a bond, one end of which is fixed on the cantilever end of the beam, and the other end is fixed on the upper part of the rotary support, which has a greater height than the first and second fixation supports.

The essence of the proposed technical solution is illustrated by drawings, which show:

FIG. 1 - General view of the anti-ram device;

FIG. 2 is a view A in FIG. one.

The anti-ram device (Fig. 1, 2) contains mounted and rigidly fixed on reinforced concrete bases 1, dug into the ground, a rotary support 2, the first 3 and second 4 fixation supports, as well as a beam 5 mounted with the possibility of rotation in the horizontal plane. One end of the beam 5 is fixed to the first fixing support 3, and the other end is fixed to the rotary support 2 and to the second fixing support 4 jointly installed with it (Fig. 1). The pivot bearing 2 is equipped with an articulated mechanism for moving the beam 5, and the first 3 and second 4 fixing supports are equipped with mechanical locking devices 6 (Fig. 1), in which the ends of the beam 5 are fixed, forming an additional passive hook during ramming. The pivot bearing 2 is additionally mounted on a reinforced concrete base 1 with scarves 7 (Fig. 1, 2), which are designed to hold (protect) the pivot bearing 2 from displacement during ramming. In the beam 5, a pre-tensioned annular rope 8 (Fig. 1) of steel is mounted and fixed at its ends, which, when the vehicle deforms the beam 5 in the closed position, is firmly fixed at its ends with metal trunnions. The beam 5 in a horizontal position is supported by communication 9 (Fig. 1, 2) and the rack 10 (Fig. 1). The connection 9 is a rectangular metal pipe, one end of which is fixed on the cantilever end of the beam 5, and the other end is fixed on the upper part of the rotary support 2. Moreover, to fix the connection 9, the rotary support 2 has a greater height than the first 3 and second 4 support fixation (Fig. 1). Connection 9 is an additional reinforcing element and provides reinforcement of the structure as a whole. The stand 10 (Fig. 1) is equipped with a wheel with a shock absorber, which allows you to compensate for irregularities in the road surface and to avoid difficulties when opening and closing the beam 5 of the anti-ram device. In addition, the wheel with a shock absorber is equipped with a brake, which is designed to fix the beam 5 in the open state, which eliminates the involuntary movement of the beam, possible injuries and damage to property. For the convenience of manually moving the beam 5 from the “open” position to the “closed” position and, conversely, a handle 11 is installed on its cantilever end (Fig. 1, 2).

Reinforced concrete bases 1 (Figs. 1, 2) have anchor devices 12 with nuts 13 buried in them. In this case, the first fixation support 3 and the rotary support 2 with scarves 7 and with the second fixation support 4 are mounted on metal plates 14 by welding (Fig. 2), which, in turn, are fixed on reinforced concrete bases 1 with nuts 13 screwed onto the protruding threaded parts of the anchor devices 12 (Fig. 1). This principle of fastening the supports is quite reliable and provides, if necessary, the possibility of transferring the structure without reinforced concrete bases 1 to another installation with prepared similar reinforced concrete bases.

Swivel bearing 2 (Fig. 1, 2) is made with the possibility of access to the internal nodes of the hinge mechanism, which facilitates maintenance and repair if necessary. The swivel mechanism of the rotary support 2 provides smoothness and ease of rotation. At the same time, a cap grease nipple is used to organize the supply of lubricant to the bearings. Depending on the installation location of the device, the rotary support 2 is capable of providing a rotation of the beam 5 by 270 °.

The first 3 and second 4 support fixing (Fig. 1, 2) are made the same. At the same time, their mechanical locking devices 6 (Fig. 1) contain two faceplates welded onto the upper part of each of the supports.

The design of the rack 10 (Fig. 1) provides the ability to mount a removable wheel with a shock absorber and brake. With abundant snow cover, as well as with freezing ice instead of a wheel, rack 10 can be equipped with a mini-ski of a special design. It should be noted that the horizontal position of the beam 5 when opening or closing is provided without installing the rack 10 with a wheel or other supporting elements.

Installation of anti-ram device at the facility is as follows.

Reinforced concrete base 1 (Fig. 1, 2) is dug into the ground on the side of the roadway. Then, the supports of the anti-ram device are installed, for which metal plates 14 (Fig. 2) are installed on reinforced concrete bases 1, which are fixed to them by means of anchor devices 12 (Fig. 1) with nuts 13 (Figs. 1, 2). On metal plates 14, by means of welding, a rotary support 2 with kerchiefs 7 and a second fixation support 4 are mounted on one side of the carriageway and the first fixation support 3 on the other side of the carriageway (Fig. 1, 2). After that, a beam 5 with a stand 10 and a connection 9 are mounted (Fig. 1, 2). In this case, the distance between the rotary support 2 and the first fixation support 3 depends on the width of the overlap of the carriageway and can be standard from three to six meters. Also, depending on the width of the carriageway (with a width of 12 meters or more), it is possible to use two or more anti-ram devices simultaneously installed across the entire width of the carriageway and opened depending on the direction of vehicles. Installation of the anti-ram device at the facility does not provide for road blocking during its installation, which does not create problems for the movement of vehicles. The distance from the upper plane of the beam 5 to the carriageway should be no more than 800 mm. At this height, beam 5 will interact with the front suspension of almost any heavy vehicle, regardless of its mass and speed.

The design strength of the main components of the anti-ram device exceeds the design strength of the main components of the front suspension of ZIL-4331, KAMAZ-5320, ZIL-131, the value of which reaches 16 tons. So, the anti-ram device allows you to forcibly stop the vehicle by damaging it and creating a stop that impedes further movement.

The anti-ram device can be made of the following materials: rotary support 2 of pipes with a diameter of 100 ... 325 mm; the first 3 and second 4 fixing supports from the channel No. 16-18; beam 5 and connection 9 from a rectangular pipe 100 × 150; annular rope 8 from a steel cable with a diameter of 15 ... 20 mm; faceplates and end plates made of steel with a sheet thickness of 10 ... 20 mm.

Thus, the proposed technical solution allowed us to create a reliable anti-ram device with a simple and robust design, providing high barrage properties.
