Description

The utility model relates to mechanical devices, in particular to anti-ram barriers, and can be used to detain vehicles in an attempt to unauthorized entry/passage to the territory (from the territory) of a protected facility or to a subject of protection and authorized access by lifting the blocking element of the cantilever fastening.

Known barrier automatic anti-ram (Sh AP-L) RU 115789 (E01F 13/04, Elantsev Nikolay Viktorovich (RU), Dudina Tatiana Nikolaevna (RU), 10.02.2012), containing a barrier hollow beam with power cables, one end of which is equipped with a counterweight and is mounted on an axis fixed on the main post with the possibility of beam rotation in a 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, while the bases of both racks are rigidly fixed in the foundation blocks, and the body of the locking mechanism and the axis of the main rack are connected with additional power cables located vertically and rigidly fixed in the foundation blocks of the respective racks.

The main disadvantage is the presence of a counterweight in the design of the barrage hollow beam, which significantly increases the weight of the structure. And also the presence of several power cables, namely, damage to one of the cables can lead to a deterioration in the anti-ram properties of the barrier and, as a result, to its breakage. Also, according to the authors, the presence of four additional power cables in the main and receiving racks is a disadvantage. The presence of additional power cables complicates the design of the anti-ram barrier, which leads to an increase in the cost of the barrier and complicates its installation.

Known anti-ram barrier RU 2338830 (E01F 13/10, Polishchuk Vladimir Nikolaevich (RU), Zarubina Svetlana Vladimirovna (RU), Kosheleva Tatyana Vladimirovna (RU), 21.02.2007), designed to block unauthorized passage of vehicles to special security facilities and protected areas . EFFECT: increased reliability of the barrier operation in any temperature and climatic conditions, providing the possibility of using an electric drive and control automation, increasing the strength and aesthetics of the barrier. The anti-ram barrier contains two supports made of metal pipes of different diameters with reinforcement welded into them, poured with concrete, and a beam made of two channels welded in the form of a box, in which pre-tensioned steel cables are mounted. The beam is fixed on the hinged support by means of a bushing, two bearings and a locking clutch, with the possibility of its rotation in a horizontal plane. On the castle support, it is fixed with the help of a tension knot of cables and a locking device. In a horizontal position, the beam is held by a bracket consisting of the upper part of the hinged support and two rods connected by an adjusting nut. At the cantilever end of the beam, a tension assembly is provided, consisting of two tension devices, four bolts and two end caps, which ensure reliable fastening of the beam in the locking device. If there are steel spikes on two vertical planes of the beam, they are closed with a false box, with stripes of different colors applied to its outer part.

The disadvantages of the invention are the lack of safety sensors, signal beacons and traffic lights in the design of the anti-ram barrier, allowing a safe cycle of lifting/lowering the barrier boom.

Another disadvantage is the absence of barrier boom position sensors in the design, which does not allow sufficient control over the process of lifting/lowering the boom.

Also, the disadvantage of the anti-ram barrier is the lack of the possibility of emergency raising / lowering the boom. According to the patent, this barrier is made either with a manual or with an electromechanical drive.

The closest analogue, according to the applicants, is the anti-ram barrier RU 2621774 (E01F 13/10, Closed Joint-Stock Company "Center for Special Engineering Structures of the Research and Design Institute of Radioelectronic Technology" (ZAO "CeSIS NIKIRET", RU), designed to create a physical obstacles in an attempt of unauthorized entry of vehicles into the territory or exit from the territory of protected objects of any class of significance.Technical result - increased reliability, maintainability and performance of the device.Anti-ram barrier consists of main (power) and auxiliary structural elements.The main elements are steel ropes, pins and supports, forming a single closed power system with the foundation.Auxiliary elements include the boom, frame, counterweight, electric drive and casing.The boom is made in the form of a truss of steel closed rectangular profiles.At both ends of the boom are w tyri, made in the form of cylinders of high-strength steel. Inside the upper and lower chords of the truss, steel ropes run around the pins, forming a closed system. The arrow shank is clamped in one of the counterweight nodes, forming a sliding seal with it. The boom and counterweight are balanced on an axis mounted on the frame, with the ability to move the boom in a vertical plane using an electric drive. The supports are box-section racks, each of which is formed by two paired I-beams. The bases of the supports and the frame have a rigid interface with blocks of foundation bolts, which, in turn, are located in the body of the foundation.

The disadvantages of the considered anti-ram barrier is the implementation of the boom in the form of a farm of steel closed rectangular profiles. Such an execution of the boom leads to a lighter structure, but reduces its strength characteristics. Another disadvantage is the lack of security sensors, signal beacons and traffic lights that ensure the safe opening and closing of the barrier boom.

Another disadvantage is the presence of a counterweight, which not only complicates, but also significantly weights the design.

Another disadvantage is the absence of barrier boom position sensors in the design.

These disadvantages are solved in the claimed utility model.

The technical problem solved by the claimed utility model is expressed in the expansion of the arsenal of technical means for the safety of using a barrier-type anti-ram device, which includes security sensors, signal beacons and traffic lights located on the signal post, and due to the possibility of emergency raising and lowering the barrier boom.

The technical result is to improve the technical and operational characteristics of the barrier-type anti-ram device due to the use of a safety sensor, a signal beacon and a traffic light as part of the anti-ram device, ensuring its safe operation.

To achieve the claimed technical result, a barrier-type anti-ram device is proposed, located on a foundation fixed to the ground or roadway and representing a metal structure consisting of a ramp, a rack in which a blocking element is mounted, a receiving block located on the foundation, while the blocking element is a barrier boom reinforced with a steel cable that blocks the passage while in the lower position, while the barrier boom is fixed by an electromagnetic drive brake connected in parallel with the engine, which is activated when the supply voltage is removed from the barrier drive, characterized in that the control of the position of the barrier boom is carried out due to the presence of an encoder and at least one position sensor of the barrier boom and each position of the barrier boom corresponds to certain states of at least one position sensor and encoder, and if the signal does not match to at least one position sensor and an encoder, the drive stops, and the safe use of the anti-ram device is carried out due to the presence of safety sensors, when the beams of which cross, during the movement of the barrier boom, the drive stops.

At the same time, the anti-ram device of the barrier type is made with the possibility of emergency raising/lowering the barrier boom by lowering the brake release lever.

Also, an anti-ram device of a barrier type can be equipped with signal stands fixed on the stand and the reception stand from opposite sides, with traffic lights, beacons and sound annunciators located on them.

These advantages of the utility model, as well as its features, are explained using the best version of its implementation with reference to the attached drawing.

The anti-ram device of the barrier type contains a foundation part 1, with a ramp located on it (not shown in the figure), on which, on opposite sides of the ramp, the main rack 2 is located on one side, in which the barrier drive is located (not shown in the drawing), position sensors the barrier booms and the encoder (not shown in the drawing), covered with a housing of the motor-reducer 4, covering the main rack 2 and preventing the ingress of precipitation, and on the other hand, the receiving rack 8, on which the barrier boom 7 is lowered, in which the steel cable is located, as a power element (not shown). In addition, on the main post 2 there is a casing of the motor-reducer 4, a steering wheel 3 for manually raising or lowering the barrier boom 7. On the main post 2 and on the reception post 8 there are safety sensors 6 and signal posts 5 containing signal beacons and traffic lights.

The barrier-type anti-ram device has two modes of operation:

automated - a mode in which the anti-ram device is controlled by commands from the operator's workstation and from the control panel;

emergency - a mode in which all actions are performed manually by the operator, designed for cases of power failures.

The operation of the barrier-type anti-ram device is carried out as follows.

In automatic mode, control is carried out using the control board located in the operator's workstation or from a control panel located separately from the anti-ram device. The control board, receiving signals from the encoder, position sensors and safety sensors (not shown in the drawing) located under the casing covering the main rack 2, controls the barrier drive (not shown in the drawing), signal racks 5, equipped with traffic lights, beacons and sound annunciators.

On command from the object's security system, or when buttons are pressed, the control board analyzes the command, analyzes the state of the encoder, position sensors and safety sensors 6, turns on beacons, and, if necessary, the red section of traffic lights located on signal stands 5, and sound annunciators . After that, the signal from the control board goes to the frequency converter, which supplies current to the drive of the anti-ram device. The barrier drive has in its design an electromagnetic brake connected in parallel with the motor, which is activated when the supply voltage is removed from the barrier drive.

An encoder and position sensors are used to control the position of the barrier boom 7. When the barrier boom 7 approaches the extreme position, the corresponding position sensor is triggered. The control board, after analyzing the state of the position sensor and encoder, gives a command to stop the drive. Each position of the barrier boom 7 corresponds to certain states of the position sensors and the encoder. If the signal of the position sensors and the encoder does not match, the drive stops. At the same time, the EMERGENCY STOP indicator will turn on on the operator's workstation or on the control panel.

To prevent people and vehicles from entering the working area of the barrier boom at the moment of its movement, infrared safety sensors 6 are used, when their beams cross, during the movement of the barrier boom 7, the control board stops the drive. At the same time, the indicators "EMERGENCY STOP" and "OBJECT IN THE WORK AREA" turn on on the operator's workstation or on the control panel.

The beacon, the sound annunciator and the traffic light ensure the safe operation of the anti-ram device, characterized by the following features: when the barrier boom is raised, the beacon turns on, signaling the beginning of the opening (closing) cycle of the anti-ram device, while the sound annunciator gives an audible signal, and the traffic light turns on red.

At the end of the opening cycle, after the anti-ram device is completely stopped, beacons and sound annunciators are turned off, and the traffic light switches to green.

The operation of the anti-ram device when the barrier is closed is similar.

In emergency mode, the operation of the anti-ram device - raising / lowering the barrier boom 7 is done manually. To do this, it is necessary to completely de-energize the anti-ram device by turning off the power supply. Next, the operator needs to lower the release lever 9 located behind the door of the casing of the motor-reducer 10 and remove the handwheel 3 located at the attachment point (next to the gearmotor) and install the handwheel 3 on the end section of the drive shaft 11,

hidden behind the second door of the casing of the motor-reducer 12, located on the casing of the motor-reducer 4.

If the barrier boom 7 is in the upper position for a long time in emergency mode, it is necessary to lift the brake release lever 9 to block it.

The most successfully declared barrier-type anti-ram device can be used as a means of preventing the passage of vehicles to and from the territory of protected objects. The inventive anti-ram device, due to the presence of a cable power element, stops a vehicle weighing up to 25 tons moving at a speed of 30 km/h.
