RU39609U1 - UNAUTHORIZED DRIVING PREVENTION SYSTEM - Google Patents

Abstract

The utility model relates to barrage devices, and more specifically, to means that impede the promotion of transport.

The system for preventing unauthorized passage of vehicles contains blocking elements located in the recess of the roadway, each of which is pivotally connected to the traction by means of levers, actuators for raising and lowering the blocking elements, a control panel and a drainage grill.

In order to reliably prevent the advancement of vehicles and further maintain the system’s operability while ensuring ease of operation, each blocking element is equipped with an additional drive and rod, as well as a beam, while the rods are pivotally connected to the beam, which in turn is pivotally connected to the levers. Drives are located under the drainage grill and the roadway.

Description

The utility model relates to barrage devices, and more specifically to means that impede the promotion of transport.

Known barrage device published in the advertising brochure of the Scientific and Technical Center "Reducer" ("Nomenclature of the enterprise", St. Petersburg, 10.2002, part 2, p. 18). This barrage device is a blocking band of synchronous action, containing blocking elements located in the recesses of the roadway, each of which is rigidly fixed to the shaft, and the shaft rotation drive.

This blocking strip does not reliably prevent the movement of vehicles, since with the ram, the whole strip can be tipped over, and not each blocking element individually.

There is also known a system for preventing unauthorized passage of cars according to the patent of the Russian Federation No. 1799452 (publ. 02.28.93), containing locking elements located in the transverse recess of the roadway, each of which is mounted on the shaft, a drive for lifting and lowering the locking elements with horizontal traction and a control panel . The locking elements are connected to the horizontal link through levers. An electric scraper conveyor is located under the blocking elements and the drainage grill. This system of preventing unauthorized passage of vehicles is the closest to the proposed one.

As a result of the installation of the blocking elements of this system in a vertical operating position, car tires may be punctured, but the car cannot be completely stopped.

The proposed utility model solves the problem of reliably preventing the advancement of vehicles when attacking a guarded

object of terrorists, as well as further maintaining the system’s operability while ensuring ease of operation.

To achieve this technical result, in the system for preventing unauthorized passage of vehicles containing blocking elements located in the recess of the roadway, each of which is pivotally connected with traction via levers, a drive for raising and lowering the blocking elements, a control panel and a drainage grill, each blocking element is equipped with an additional drive and traction, as well as the beam, while the rods are pivotally connected to the beam, which in turn is pivotally connected with levers, except t On the other hand, the drives are located under the drainage grill and the roadway.

Distinctive features of the proposed system for preventing unauthorized passage of vehicles from the above known, closest to it, is that each blocking element is equipped with an additional drive and rod, as well as a beam, while the rod is pivotally connected to the beam, which in turn is pivotally connected to levers, in addition, the drives are located under the drainage grid and the roadway.

Due to the presence of these signs during unauthorized passage of vehicles, their chassis is damaged or a mechanical stop is created. Unlike the prototype, the locking elements cannot be wrinkled or turned into a horizontal inoperative position by heavy vehicles, since the locking elements are hardened and additionally equipped with a drive and traction. In case of damage to the blocking elements, when removing the drainage grate, they can be replaced.

The proposed system to prevent unauthorized passage of vehicles is illustrated by the drawings presented in figures 1, 2.

Figure 1 shows a General view of the system;

figure 2 is the same, a top view (without drainage grate).

The system for preventing unauthorized passage of vehicles contains blocking elements 1 located in the recess of the roadway 2 and under the drainage grill 3. Each blocking element is pivotally connected by levers 4 to the rocker 5 and rods 6 with the lifting and lowering drives 7. The lifting and lowering drives are located under the drainage grill and roadbed and equipped with a control panel 8.

The operation of the system to prevent unauthorized passage of vehicles is as follows.

When you press the "Start" button on the control panel 8, an electrical signal is supplied to the lifting drives 7, which move the link 6, pivotally connected to the beam 5 and lever 4. The lever 4 raises the blocking element 1 and puts it in working position above the level of the roadway 2. The blocking element 1 is made of a thick-walled pipe.

To return the blocking element 1 to the inoperative position, that is, flush with the roadway 2 and the drainage grill 3, the Reset button is pressed on the control panel 8. An electrical signal is supplied to the lowering drives 7, which through the rods 6, the rocker 5 and the lever 4 lower the locking element 1 to the inoperative position.

Raising the rigid blocking elements and lowering them flush with the roadway increases the reliability of the system to prevent unauthorized passage of vehicles, as the undercarriage is damaged and a mechanical stop is created. The presence of two drives for raising and lowering the locking elements makes the system even more reliable. The performance of the system is maintained for a long time, due to the convenience of its repair and maintenance.

Claims (1)
