Description

The utility model relates to devices for ensuring traffic safety, mainly rail transport, at the intersection of rail and road transport. The device is designed to prevent the departure of vehicles when moving trains on it. The device can also be used as a road barrier installed in front of a guarded enterprise or at a pedestrian intersection.

Enclosing devices at level crossings are also known, for example, automatic traffic lights with automatic barriers and level crossing devices. [Automatic traffic light devices with automatic barriers, "Systems of railway automation and telemechanics", ed. Doctor of Technical Sciences Yu.A. Kravtsova, Moscow, Transport, 1996, pp. 181-192]; ["Rail Transport. Encyclopedia", Moscow, Big Russian Encyclopedia, 1994, pp. 297, 498-499].

Also known are various barrage devices for railroad crossing barriers [RU patent for invention No. 2270777, RU patents for utility models No. 23066, No. 25875]. These devices comprise a support base on which a cover is pivotally mounted and a drive shaft is mounted. One end of the drive is connected to the cover coaxially to the hinges, and at the other end is a counterweight bracket rigidly attached to the drive gate.

The closest analogue to the claimed utility model is a “Barrier element for a railroad crossing fence device” [RU patent for invention No. 2156200], comprising a cover from rolling sections with a continuous sheet superimposed on them. The cover is mounted on the base across the road flush with its coating. The base is placed on the foundation. A counterweight is mounted on one side of the drive shaft, which is connected via a rod to the drive of the barrier element. The drive shaft is placed in the bearing bearings of the base and is closed on top with a solid sheet. A removable cover bracket is mounted on the other side of the shaft. There is a friction shock absorber slider type to regulate the braking of the counterweight. The edges of the sheets forming the surface of the barrier element are cut parallel to each other tangentially to the trajectory of rotation of the edge of the lid and are paired with each other with the possibility of lifting the latter. Brackets for mounting hinges are welded to the lid, the axis of rotation of which is outside the contour of the outline of a continuous sheet of the lid.

The operating experience of these barrier elements for railroad crossing fencing devices has shown the following significant drawbacks that determine low reliability, durability and maintainability in operation:

- the large mass of the floor cover causes inertial and, accordingly, dynamic loads acting on the drive elements, especially at the beginning and at the end of lifting the cover, opening the drive automatic switch lock at the beginning of the cover lifting leads to an instant (shock) application of the cover gravity transmitted through its bracket to drive shaft and drive elements; significant dynamic loads applied to the drive also occur at the end of the lifting of the cover when the kinetic energy (stopping) of the moving masses of the cover and the drive is extinguished; the above causes increased wear of drive parts and its failures;

- significant metal costs for the manufacture of floor coverings, which make up 30% of the total mass of the barrier element;

- the increased overall dimensions of the barrier element due to the presence of an electric drive with a mechanical headset in some cases do not provide the necessary dimensions for approaching the buildings to the railway track when it intersects with the road at an acute angle, which imposes restrictions on the placement of the barrier element relative to the railway track.

The objective of the proposed solution is to simplify the design without compromising reliability, as well as saving energy costs during the operation of the transport locking device.

The essence of the claimed utility model lies in the fact that in the transport blocking device, consisting of a support base, a barrier and an electric drive mechanism that drives the barrier, the electric drive mechanism has two stators serving as actuators equipped with end shock absorbers, a movable rotor in the form of a counterweight with a shape a guide cup moving along the bar inside it, and a control unit associated with a traffic light signaling device.

The technical result of the utility model is to simplify the designs and save operating costs of the inventive device due to the design of the electric drive mechanism introduced into the blocking transport device.

The type of electric drive recommended in the claimed solution does not require the use of additional units, in particular, a gearbox, which also saves the cost of a locking device.

The inventive utility model is illustrated using Fig.1-2, which show: Fig.1 is a schematic illustration of a transport locking device, Fig.2 is a diagram of an electric drive mechanism, where positions 1-8 indicate:

1 - supporting base;

2 - a barrier;

3 - electric drive mechanism;

4 - stators;

5 - movable rotor;

6 - end shock absorbers;

7 - rod;

8 - control unit.

The transport locking device consists of a support base 1, a barrier 2 and an electric drive mechanism 3, which drives the barrier 2. The electric drive mechanism 3 has two stators 4, a movable rotor 5. The stators 4 serve as actuators equipped with end shock absorbers 6. The rotor 5 is made in the form a counterweight with the shape of a guiding glass moving along the rod 7 inside it. The transport locking device has a control unit 8 connected to a traffic light signal device.

The transport blocking device is installed across the carriageway of the road. The barrier 2 in the raised state notifies the driver, approaching the move about the prohibition of entry to move.

The electric drive mechanism 3 is placed outside the carriageway of the road and in most cases is fenced, preventing unauthorized persons from entering the area of its operation.

When the rotor 5 is in the lower stator 4 and the barrier 2 is turned on, the control unit 8 supplies voltage to the stator 4 in such a way that the resulting traveling magnetic field pushes the counterweight - rotor 5 out of the stator 4.

The rotor 5 in the form of a counterweight moves along the rod inside it 7 to the upper stator 4 and is braked there using the end shock absorber 6, while the center of gravity of the device is shifted to the upper point of the rod 7. The barrier 2 rotates counterclockwise by 30 ° and blocks the carriageway the road.

To turn off the barrier 2, the control unit 8 switches the upper stator 4 to form a running magnetic field in the direction of the lower stator 4. Due to the mass of the front beam, the center of gravity shifts down to the support base 1, the barrier 2 rotates clockwise by 30 ° and the device opens the driveway part of the road.

Example.

The inventive device developed is transferred for experimental production to one of the plants in Saratov.
