RU46572U1 - Anti-barrage device - Google Patents

Abstract

The utility model relates to controlled blocking devices, and more specifically, to anti-ramming means that impede the promotion of vehicles at the entrance and exit from the territories of protected objects. The anti-ram barrage device contains blocking elements installed in a power metal structure mounted in a concrete foundation in the roadway. Each blocking element is provided with a centering roller and a lifting and lowering drive located in a power metal structure and actuating a gear rack rigidly connected to the blocking element. The technical effect of improving work efficiency due to the hidden placement of the device on the road and the possibility of unexpected use.

Description

The utility model relates to controlled blocking devices, and more specifically, to means that impede the promotion of vehicles at the entrance and exit from the territories of protected objects.

A known system for preventing unauthorized passage of cars according to the patent for utility model of the Russian Federation No. 39609 (publ. 10.08.2004), containing blocking elements. Each blocking element is equipped with levers, rods and a rocker, a lifting and lowering drive located under the drainage grill in the recess of the roadway, a control panel. The rods are pivotally connected to the beam, which in turn is pivotally connected to the levers.

A disadvantage of the known system for preventing unauthorized passage of vehicles is the unreliability of work in case of failure of one of the drives or swivel joints.

From this drawback, the UPU-001 free-blocking device, published on the Internet advertising website (www.zaotranzit.narod.ru), which is a prefabricated-welded power metal structure mounted in a concrete foundation in the roadbed. Two cavities are formed by the frame elements, in which blocking elements are mounted, fixed on the shaft. From the control panel, the shaft is rotated from the gear motor located on the foundation on the side of the roadway. To prevent unauthorized passage, by means of a gear motor, the blocking elements take a vertical position.

In the known blocking device closest in technical essence to the proposed system, there is no moment of surprise. Even horizontal locking elements

visible from afar. In addition, the architectural appearance of the protected structure is disrupted.

The proposed utility model solves the problem of increasing work efficiency due to the hidden placement of the device on the road and the possibility of unexpected use.

To achieve this technical result, in an anti-ram barrage device containing blocking elements installed in a power metal structure mounted in a concrete foundation in the roadway, a drive for raising and lowering the blocking elements, a control panel, each blocking element is provided with a centering roller and a drive for raising and lowering, located in a power metal structure and actuating a gear rack rigidly connected to the blocking element.

Distinctive features of the proposed anti-ram barrage device from the above known closest to it is that each blocking element is provided with a centering roller and a lifting and lowering drive located in a power metal structure and actuating a gear rack interacting with the blocking element.

Due to the presence of these signs, an unexpected use of an anti-ram barrage device and an increase in its operational efficiency is possible.

The proposed anti-ram barrage device is illustrated by the drawings shown in figures 1, 2.

Figure 1 shows a General view in section;

figure 2 is the same, a top view.

The anti-ram barrier device contains blocking elements 1 installed in a power metal structure 2 mounted in a concrete foundation 3 in the roadway 4. Each blocking element 1 is provided with a centering roller 5 and a drive

raising and lowering 6, located in the power metal structure 2 and driving a gear rack 7, rigidly connected to the blocking element.

The operation of the anti-ram barrage device is as follows.

When you press the "Start" button on the control panel 8, an electric signal is supplied to the lift drive 6, which moves the gear rack 7 through the gear 9 and with it the blocking element 1. The blocking element 1 is installed in the working position above the level of the roadway 4.

To return the blocking element 1 to the inoperative position, that is, flush with the roadway 4, the Reset button is pressed on the control panel. An electric signal is supplied to the lowering drive 6, which through the gear rack 7 lowers the blocking element 1 to the inoperative position.

Claims (1)
