Description

The invention relates to mechanical devices, in particular to anti-ram barriers, designed to block the unauthorized passage of vehicles to special modes and protected areas.

Known designs of mechanical barriers and barriers for detaining vehicles in the form of struts with pneumatic drive (see US 4576508 A, F01F 13/00, E01F 15/00, 03/18/1986), anti-ram devices in the form of hedgehogs with pneumatic and electric drive (see SU 1799452 A3, E01F 13/00, F41H 11/08, dated 02.28.1993) and the anti-ram barrier (see US 5997211 A, E01F 13/06, dated 07.12.1999).

The disadvantage of these devices is the low mechanical strength of the attachment points of the beams (cables) with struts (supports), the complexity of the structures and low operational properties.

Closest to the invention in essence and the technical result achieved is an anti-ram barrier containing a beam, one end of which is pivotally mounted on one support, and the other end on the other support using a locking device (see RU 2224840 C1 7 E01F 13/10, dated July 12, 2002).

This device also has drawbacks in that the cantilever end of the beam in horizontal position is supported by a strut and wheel, which makes it difficult to open and close the barrier beam when snow is covered, ice freezes or uneven road surface. With this design, it is practically impossible to use an electric drive and automate the control of the barrier.

The absence of a cable tension unit in the barrier and its connection with the end plate reduces the strength of beam fastening in the locking device, and open spikes do not allow applying the desired color to the beam and increase the aesthetics of the barrier. These factors significantly reduce the possibility of applying a barrier.

An object of the invention is to increase the reliability of the barrier in any temperature and climate conditions, the use of a cable tensioning unit, providing the possibility of using an electric drive and control automation, increasing the strength and aesthetics of the barrier.

The problem is solved due to the fact that the supports of the barrier are made of two metal pipes of different diameters and different levels in height, with reinforced concrete welded into them. The barrier beam is welded from two channels in the form of a box with steel cables pre-tensioned in it. On the hinged support, the beam is fixed with a sleeve, two bearings and a locking sleeve, ensuring its rotation in the horizontal plane by an angle of at least 90 °.

The cantilever end of the beam is fixed to the castle support using a tension unit and a locking device consisting of two faceplates with holes, a locking bolt and a special lock that fixes it. The beam in the horizontal plane is held by means of a bracket consisting of the upper part of the pipe of the articulated support and the bearing mounted in it, the upper rod and the lower rod connected by an adjusting nut, and a nut welded to the upper plane of the beam. This design of the bracket allows you to open and close the beam with the application of a minimum force (5 kg) in any temperature and climate conditions. Using the adjusting nut, the beam is exposed in the horizontal plane, and during operation, the gaps between the beam and the faceplates in the vertical plane are adjusted.

At the cantilever end of the beam, a cable tension unit is provided, consisting of two tension devices, two end plates and four M16 bolts. After tensioning the cables, the tensioning devices are welded to the channels, and the end plates are welded together and welded to the end of the beam. The ends of the plates protrude 10-15 mm above the level of the faceplates, which prevents, when ramming, tearing the end of the beam from the locking device.

The barrier can be made with either manual or electric drive. With a manual drive, the cantilever end of the beam is displayed and inserted into the locking device manually using the handle, and the beam is locked with a bolt, which is fixed with a special lock. With an automatic drive, the cantilever end of the beam is brought out and brought into the locking device using an electric motor gearbox, the beam in the locking device is fixed with an electromagnetic lock and automatically locked by an electromagnet anchor, for this you must first press and release the button on the barrier control station.

Opening time - closing the barrier from 10 to 30 seconds.

To compensate for the linear elongation of the beam when the air temperature drops from -50 ° C to + 50 ° C, an oval hole is provided in the beam for a locking bolt or an anchor of an electromagnet.

To increase the barrage properties, steel spikes can be welded on the vertical planes of the beam. In order to increase the aesthetics of the barrier, the spikes are closed with a false box made of thin galvanized roofing sheet. The outside of the false box is covered with multi-colored reflective stripes.

When a vehicle hits the barrier beam at an angle from the bottom up to prevent the beam from breaking out, a locking sleeve is provided on the hinge support, and four kerchiefs welded to the pipe and upper faceplate on the castle support.

Comparison of the proposed solution not only with the prototype, but also with other technical solutions in the art did not allow them to identify signs that distinguish the claimed solution from the prototype, which allows us to conclude that the criterion of "inventive step".

The barrier supports are concreted into the ground at the curbs of the carriageway to a depth of approximately 1.5 meters. The distance between the supports depends on the width of the overlap of the carriageway and can be from 3 to 8 meters.

The distance from the upper plane of the beam to the carriageway should be 500-600 mm. At this height, the beam will interact with the front suspension of almost any heavy vehicle, regardless of its mass and speed.

When the supports are located on a line perpendicular to the center line of the road, the barrier beam will be at an angle of 3-4 ° with respect to the center line of the road. This is achieved by displacing the pipe of smaller diameter in the pipe of a larger diameter of the castle support. In this case, the barrier will perceive the ramming force of the impact at the initial time from one wheel of the vehicle.

The design strength of the main nodes of the anti-ram barrier is 50 tons, the design strength of the main components of the front suspension of the ZIL-4331, KAMAZ-5320, ZIL-131 vehicles is from 5 to 16 tons.

The barrier can be made: supports from pipes with a diameter of 325-100 mm, channels No. 16-18, steel cables with a diameter of 15-20 mm, faceplates and end plates - steel sheet with a thickness of 10-20 mm.

Figure 1, Figure 2 and Figure 3 shows a General view and the main nodes of the barrier.

The barrier comprises a hinge support 1, a locking support 2, a beam 3, a locking sleeve 4, a locking device consisting of two faceplates 5, a bolt 6, a tension unit containing two tension devices 7, two end plates 8, four bolts 9, an arm containing the upper part of the hinge bearing 10, the bearing 11, the upper thrust 12, the lower thrust 13, the adjusting nut 14, the nut on the upper plane of the beam 15, steel spikes 16, the false box 17, on the castle support of the scarf 18 can be welded on the vertical plane of the beam gearbox 19, electromagnet 20, electromagnets the lock 21, steel cables 22, special lock 23, handle 24.

The increased strength and operational properties of the barrier, the expanded possibilities of its use in any climatic and weather conditions, both with manual and electric drives and automatic control, with minimal dimensions and material consumption, as well as aesthetics of its appearance and safety of use, make it possible to use the proposed a barrier for equipping entrances and exits to guarded special regime facilities, government agencies, military units, industrial enterprises and checkpoints.
