Description

The invention relates to lifting and transporting devices, in particular, for unloading bulk cargo from railway gondola cars and can be used in all sectors of the national economy associated with unloading and cleaning railway gondolas from bulk cargo.

The purpose of the invention is to increase the productivity of unloading and more complete removal of bulk cargo.

Figure 1 shows the machine, a general view; figure 2 - section aa in figure 1 (the working bodies of the machine in the initial position); in fig.Z - the position of the unloading device of the machine in the process of unloading the car; figure 4 - the position of the cleaning device of the machine in the process of cleaning the car.

The machine contains a self-propelled gantry 1, on the cross beams of which a carriage 2 is installed with support posts supporting the vertical guides 3 for the unloading device 4 and the vertical guides 5 for the cleaning device 6 formed by a vertical elevator, in the lower part of which raking screws are horizontally mounted. On the longitudinal beams of the portal, the receiving reversing conveyor 7 is permanently installed and the dump conveyors 8 and 9 are suspended.

On the carriage 2, a casing 10 is installed, covering the discharging device 4. In the lower part of the casing 10, a wallpaper grid 11 is installed, protecting the receiving conveyor belt 7 from direct falling of large pieces of bulk material. Vertical guides 3 and 5 for the discharge and cleaning devices, respectively, are hinged on hinges 12 and 13, and in the lower part are pressed by elastic elements 14 and 15 to sensors 16 and 17.

In the lower part of the unloading device 4 between the two parallel branches of the elevator buckets, an emphasis 18 is installed in the form of a sector whose diameter is larger than the forming buckets moving in the loading section of the elevator. Difference

between the diameter of the stop 18 and the forming buckets provides the smallest residue of bulk material for cleaning after unloading.

The machine works as follows. Portal 1 of the vehicle moves along a rail track within which railway tracks of the rolling stock are located. Machine direction

indicated by an arrow in FIG. The carriage 2, carrying the working bodies 4 and 6, is mounted above a railway carriage located on one of the railway tracks. Unloading device 4 with

working buckets along the guides 3 are lowered down until the stop 18 contacts the bottom of the carriage. The movement of the portal 1 is turned on and the machine moves along the car, unloading it. Bulk

the load is scooped by buckets of the unloading device 4 and through the casing 10 covering the unloading device, through the baffle lattice 11 enters the reversing receiving conveyor 7. Depending on the direction of unloading, bulk material is fed to the dump conveyors 8 or 9 and further to the dump or another type of transport, Approaching the end wall of the car, the unloading device 4 rises up and

car moves to the next car. The unloading process is repeated.

During the unloading of the car, it is possible that the speed of movement of the portal 1 of the machine is ahead of the unloading speed of the bulk cargo. In this case, the unloading device 4 deviates from the vertical with the guides 3 suspended in the hinges 12, the sensor 16 is activated (limit switch) and the movement of the portal 1 stops.

The operating elevator of the unloading device 4 selects the bulk cargo and with the help of the elastic element 14 in the form of a spring returns with the guides 3 to the initial state. The sensor 16 is activated and the automatic movement of the vehicle occurs. Car unloading continues.

In addition, it is possible that there are various foreign objects hidden in the car body hidden by the main bulk cargo (concrete beams, pieces of rolled metal, large blocks, etc.). Similarly, a deviation from the vertical of the unloading device 4 with guides 3 occurs, the sensor 16 is activated, and the movement of the machine is stopped. Foreign objects are removed and the unloading process continues. Having finished unloading the filed composition of the cars, the machine reversely cleans them. The direction of movement of the machine during cleaning is shown by an arrow in FIG. 4.

During the cleaning of the car, it is possible that the front brush of the cleaning device b is overloaded, deviations of the guides 5 from the vertical with the cleaning device 6 suspended from the hinges 13 occur. As the resistance of the bulk cargo is eliminated, the cleaning device 6 with the guides 5 returns to its original vertical position with the help of an elastic element 15. The sensor 17 triggers and the machine continues to move, thus removing the bulk material.

If necessary, the carriage 2 adjusts the position of the cleaning device 6 relative to the railway car. Along the vertical guides 5 with a winch cleaning device 6

Says to the bottom of the car. The movement of the portal 1 is turned on, and the machine, moving along the car, removes the remains of the bulk cargo after the unloading device 4 is in operation.

The cleaning device 6 cleans the gondola from the remnants of the bulk cargo and with the help of an elevator delivers the harvested material to the receiving reversing conveyor 7. Depending on the discharge direction, the remains of the bulk cargo fall on the dump conveyors 8 or 9 and further to the dump or on another type of transport. Having finished unloading one car, the car moves to another, etc.
