Train working vehicle and method of operation without operator

 

The invention relates to railway working vehicle. Train the working vehicle has a frame supported on the track by means running gears and having performed with the possibility of movement along the height of the working platform with a control device for actuating the mechanism to move. On the front side of a rail vehicle is located rangefinder contactless actions associated with the control device and having a plane reading, concluding with the plane of the path formed by rail, angle and serves to form a line reading, formed by the plane of the path and the plane of the reading and perpendicular to the longitudinal direction. The way to recognize obstacles in the field of railway track in front of the railroad vehicle, when continuous contactless reading area of the track, in the direction directly in front of the railroad vehicle, automatically stop the vehicle as soon as when reading registration obstacles, Nava. The technical result of the invention is the creation of a railroad worker vehicles, which can be easily controlled with a working platform. 2 N. and 6 C.p. f-crystals, 2 Il.

The invention relates to railway working vehicle having a frame supported on the track by means running gears and having performed with the possibility of movement along the height of the working platform with a control device for actuating the mechanism to move and also way of operating unmanned railway working vehicle configured to travel on the track.

In respect of such railway workers vehicles there is a problem, namely, that workers are on the job site, can't see part of the road, directly in front of the vehicle. In addition, workers are busy doing their jobs, and by changing the position of the working platform see track differently. Therefore, to manage the railway vehicle from operating platform is extremely dangerous and zaa DE 19721901 A1, 13.11.1997, G 01 S 13/93, 61 L 23/04) using radar systems. Thus the corresponding region of the track in front of the railway vehicles subject to emission of so-called lobe of the radar antenna. The rays of the radar system are reflected from contained in the track and having a certain arrangement of reflectors and perceived radar device mounted on railway working vehicle. Located on the track obstacle overlaps one or more reflectors, resulting in the loss of the expected echo. This lack of signals can be interpreted as the presence of obstacles and taking into account resolution radar to determine the location of obstacles.

Of technology (US patent 5429329 A, 04.07.1995, 61 L 1/00) it is known that it is necessary to control approximately 1-2 miles of rail track in front of the passenger or freight train using self-propelled auxiliary rail vehicle. With cameras following driver receives the image track in front of self-propelled auxil the materials for timely braking of the train.

The objective of the proposed invention is to provide such a railroad worker vehicles of the specified type, which can be easily controlled with a working platform.

According to the invention this task is solved with the help of a railroad worker, the vehicle of the specified type in such a way that its end face is rangefinder contactless steps to the plane of the reading, which concludes with the plane of the path formed by rail, angle and serves to form a line reading, formed by the plane of the path and the plane of the reading and perpendicular to the longitudinal direction of the path.

Thanks to this performance is a railroad worker vehicles reliably ensures that the workers are on the job site, not even passing the obstacles that cannot see, and vehicle time stops. Thus, for workers it has the advantage that they can fully concentrate on their work. It is advisable that when approaching the obstacle signal, turning the attention of workers in a dangerous situation, so that they may not suffer from a sudden stop of the machine.

is Rajah.

The invention is described in more detail below using the example of execution represented in the drawings.

Fig.1 is a side view of a railroad worker vehicles;

Fig.2 is a simplified top view of a fragment of a railroad worker vehicles.

Train the working vehicle 1 shown in Fig.1 and 2, is made with the possibility of movement on the track 3 by means of running gears 2 in the working direction 4. On the frame of the vehicle 6 having a driver's cab 5, strengthened the working space 8, is arranged to move in height by means of the actuator 7. The mechanism for moving 9 is driven with the power block 10.

At each end face 11 of the frame 6 of the vehicle is rangefinder contactless actions 12. He sends a pulsating laser beam 13, which after reflection newly registered in the finder 12. The time between the release and reception of the laser beam 13 is directly proportional to the distance between the range finder 12 and the object causing the reflection. Using the mirror-turning device, not represented here, the laser beam 13 is deflected and the pattern of rasmala obrazovannoi by 3, the angle of inclination, forming a common line read 16 perpendicular to the longitudinal direction of the machine or path.

For greater reliability provided by the first and second or front and rear plane of the reader 14, each of which has a different angle of inclination. The front plane of the reader 14 with the front line read 16 having a smaller angle of inclinationserves for activation of acoustic signal device 17 via the control unit 19, as soon as using the range finder 12 is register 18 obstacles in the path 3. This is the case when due to the reflection of the laser beam 13 from the obstacle 18 is reduced, the minimum distance x between the range finder 12 and the line reading 16. It is advisable to include certain permissible boundary to reduce the distance, so that not every time the slightest irregularities in the plane of the path 15 provided for incorporation of obstacles.

During operation of the working vehicle (1) is moved in a continuous contactless reading area rail transit (3) in the direction (4) directly re is th read 14 and the minimum distance of x to the range finder 12 is reduced, using the control device 19 associated with the range finder 12, an automatic actuation of the brake device 20 in combination with the interrupt load on the mechanism to move 9. Thus there is an immediate and reliable stopping the vehicle 1.

As can be seen in Fig.2, the length of each line read 16 perpendicular to the longitudinal direction of the machine, corresponds at least to the width b of the vehicle 1.
