Description

The invention relates to railway transport, and in particular to means of traffic safety at the intersection of railway and road transport.

A known method of fencing a railway crossing, including lowering the grill until it touches the roadway, as a result of which it blocks the movement of motor vehicles and prevents its collision with the train [Pat. RF 2067057, IPC B61L 29/02, 1996].

The disadvantages of this method are:

- relatively high energy consumption associated with raising the lattice to a high height and subsequent lowering;

- Significant time required to resume movement through the crossing.

The prototype is a method of fencing a railway crossing, including lifting the lid, which is a mechanical obstacle for vehicles to enter the crossing area [Pat. RF 2270777, IPC B61L 29/02, 2006].

The disadvantages of the prototype are:

- relatively large energy consumption associated with raising the massive cover and then lowering it;

- significant time required to resume movement through the crossing after the enable signal;

- the complexity of the operation caused by the ingress of debris (especially in windy weather) and snow in a niche under the lid, which requires periodic release of the niche from the specified garbage.

The objective of the invention is to remedy these disadvantages, namely improving operating conditions, improving safety, reducing power consumption and increasing speed.

The problem is solved in that in the method of fencing a railway crossing, including the installation of an artificial section of the roadway, from which, if necessary, form an obstacle that impedes the passage of vehicles through the crossing, the obstacle is formed in the form of a trap.

An obstacle is also formed in the form of a light barrier. The formation of the trap is carried out at the same time with the formation of a barrier. After the formation of the trap, at least one signal light of a traffic light is issued, allowing the train to follow through the level crossing, and when the trap is triggered, it is forbidden to fire. A traffic light is installed near the railway track in the direction of the train, and a light beam of the signal light is passed over the crossing floor at an altitude of about 1 m. The traffic light is installed on both sides of the railway track. The traffic lights are turned on at the time the crossing is closed. The traffic light is carried out in the mode of crossing signaling. The barrier is disbanded by laying it on the canvas.

These distinctive features allow you to achieve the following advantages compared with the prototype.

The formation of an obstacle in the form of a trap allows, without lifting massive structural elements, to preserve the protective function of an artificial roadbed, which is realized only when an unauthorized entry to a railway crossing is attempted. In known designs and methods, the raising and lowering of massive barrage elements occurs repeatedly, and cases of unauthorized passage are rare. As a result, a large amount of electricity is wasted, and the speed of the barrage devices is reduced due to their large inertia. Therefore, the trap significantly reduces power consumption and improves performance. In addition, since the canvas is always in a closed state, debris and precipitation do not fall there, which improves operating conditions.

The formation of an obstacle in the form of a light barrier also enhances the protective functions of the trap, preventing, for example, a motorcyclist from driving at high speed through the trap or drunk while moving. At the same time, the working conditions of drivers are improved, which more clearly see that the protective function is turned on, and access to the canvas is prohibited. All this improves operating conditions and increases safety.

The formation of a trap along with the formation of a protective barrier reduces energy consumption and improves performance.

After the trap has been set up, at least one signal light of a traffic light allowing the train to pass through the level crossing, and when the trap is triggered, the prohibition light will increase safety.

Establishing a traffic light near the railway track after crossing the train and passing a light beam of signal light over the leveling at an altitude of about 1 m also increases safety. This is due to the fact that if a stuck vehicle or cargo has fallen on the floor, the light beam will be blocked by these objects, as a result of which the driver will not see the traffic signal from far away, thereby revealing an unfavorable situation at the crossing. Such a traffic light can be installed in conjunction with a traffic light, which is currently located before the crossing, or instead of it, which seems more effective especially at maintenance-free railway crossings.

The installation of a traffic light on both sides of the railway allows in a similar way (using a light beam) to check the presence of objects to the left and to the right of the middle of the railway (according to the size of the train), which further increases safety.

Turning on the traffic light at the time the crossing is closed reduces energy consumption.

The implementation of the work of the traffic light in the mode of crossing signaling does not allow it to be confused with other traffic lights or lighting lamps, which also increases safety.

The dissolution of the barrier by laying it on the canvas allows you to lift it to a small height, which reduces performance. In addition, energy consumption is reduced.

The invention is illustrated by drawings.

Figure 1 shows a view of a railway crossing. Figure 2 shows a section of an artificial section of the roadway in the mode of passage of vehicles. Figure 3 shows a section of an artificial section of the roadway in trap mode. Figure 4 shows a section of an artificial section of the roadway with a light barrier in the mode of passage of vehicles. Figure 5 shows a section of an artificial section of the roadway with a light barrier in the trap mode. Figure 6 shows a view A of a variant of a light barrier.

The artificial section of the roadway contains a frame 1 with a fixed axis 2, on which a loop 3 is mounted, through a spring 4 connected to the frame and fixed at one end of the base 5, the other end of which is able to interact with the protrusion 6 of the frame and the cam 7 of the drive shaft 8 having the ability to interact with the emphasis 9 of the frame. A barrier element 10 with a chain 11 can be fixed on the cam, and a dwarf traffic light 13 can be installed behind the moving floor 12, the beam 14 of which passes above the floor at a height of about 1 m.

The method is implemented as follows.

The artificial section of the roadway is installed behind the barrier (figure 1). In the initial state, when the move is open, the cam 7 is in the extreme left position under the right end of the base 5, which is held in a horizontal position and pressed against the protrusion 6 of the frame 1 by means of the elastic force of the spring 4 acting on the loop 3 (figure 2). Note that there is a slight gap between cam 7 and base 5. When the vehicle hits the base 5, the weight force is transmitted through the loop 3 to the axis 2, as well as through the cam 7 (after selecting the clearance) and the shaft 8 to the stop 9. As a result, the base 5 remains in a horizontal position, allowing the vehicles to move.

To close the crossing, lower the barrier and, using the drive shaft 8, rotate the cam 7 clockwise to the right position (Fig. 3). Since there is a gap between the cam and the base, the force required to rotate the shaft is small, however, when the base of the vehicle is at that moment, this gap will not be present, which will not allow shaft 8 to be rotated between the cam and the base. This in turn, can serve as a signal of an unfavorable situation at the move. If the cam is turned to the right position, then the base 5 will be held in a horizontal position on one support (axis 2) due to the elastic force of the spring 4. This position of the base corresponds to the trap mode. Then turn on the traffic light 13 with an enable signal light. After following the train, turn the shaft 8 with the cam 7 in the initial extreme left position and resume the movement of vehicles through the level crossing.

In the case of an unauthorized vehicle hitting the base 5 in trap mode, overcoming the force of the spring 4, it will fall down, creating an insurmountable obstacle to the movement of the vehicle, the wheel of which will fail. When the trap is triggered, the enable fire at the traffic light 13 is switched to prohibit.

If, after the trap mode has been set and the enabling light of the traffic light 13 is turned on, some kind of object will appear on the floor 12, for example, a vehicle or a cargo that has fallen, then beam 14 will be interrupted by this object. As a result, the driver will not see the traffic light, which will serve as a signal for braking the train. For better control of the crossing zone, a traffic light 13 is installed on both sides of the railway line.

So that the lights of the traffic light 13 are not confused by the driver with others, the operation of the specified traffic light is carried out in the cross-signaling mode (flashing mode) during its operation.

For better visualization of the trap mode and the exclusion of passage through the trap at high speed of light vehicles, for example motorcycles, a barrier element 10 is used, which, when the vehicles are allowed to move, is in a horizontal position on the base 5 (Fig. 4). When entering the trap mode, the barrier element 10 is lifted above the base 5 at the same time as the shaft 8 is rotated clockwise, creating a light barrier that can be strengthened by chains 11 (Figs. 5, 6).

The implementation of the invention will allow you to create a convenient and easy to design device that prevents unauthorized passage of vehicles through the crossing and while consuming little energy.
