Description

one

This invention relates to the handling of rail transport.

Machines for unloading bulk cargo from covered railway cars are known, comprising a self-propelled carriage on which a support beam is mounted mounted in the doorway of the carriage, carrying an unloading conveyor and an expandable boom such as Nuremberg scissors with ends.

The disadvantage of these machines is the presence of unloaded cargo in the car.

The purpose of the invention is to increase the efficiency of discharge.

This is achieved by the fact that, in the proposed machine, each scraper is suspended to the end of the boom with the help of 1, the driving arms that form the Sharpyra and Alogram system, and is made of two parts hinged and interconnected with each other and has a tooth, the friend is made folding and has a spring-loaded latch that secures both parts of the scraper.

FIG. 1 shows the proposed machine, top view; in fig. 2 is a view along arrow L in FIG. one; in fig. 3 is a view along arrow B in FIG. one; in fig. 4 is a view along arrow B in FIG. 3

Machine for unloading bulk cargo from

of covered railway cars contains a self-propelled platform 1 moving along rails 2 along the railroad track 3, on which the self-propelled trolley 4 is located with two screw conveyors 5 mounted on it and a horizontal beam 6, and a boom is installed in both directions 7 types of Nurenber scissors.

At each end of the boom 7, a stand 8 is fixed, to which a scraper, made of two parts, is suspended by means of levers 9, which form a sharn-parallelogram mechanism. One part 10 interacts with the vibrator AND and has a tooth 12, and the other part 13 is made folding and has a spring-loaded latch 14, fixing both parts 10 and 13. On the folding part 13 of the scraper the power cylinder 15 is hinged

the other end of which is hinged on the other part of the scraper 10. One of the levers 9 is pivotally connected to the rod of another power cylinder 16, which is hinged to the post 8.

The folding part 13 of the scraper has a roller 17 in the lower part.

Rope 18 is attached to part 10 of the scraper, stocked by a winch 19, coupled to the drive 20 by a clutch 21. At the end of the beam 6

suspended on the levers 22 stripping scraper 23,

driven by power cylinders 24.

The machine works as follows.

Self-propelled platform 1 is installed opposite the unloading car 25.

A self-propelled trolley 4 with screw conveyors 5 and beam 6 with boom 7 installed on it is inserted into the doorway of wagon 25. At that, boom 7 is folded, parts 10 of scrapers are lowered, folding parts 13 are removed from latches 14, end scraper 23 lifts m. As you move into the wagon 25, the screw conveyors 5 unload the bulk cargo from the doorway area.

The coupler-coupling 21 is turned on, freeing the drum of winch 19, and lifting of parts 10 of the scrapers begins with simultaneous lifting of folding parts 13. To facilitate lifting of the scrapers when unloading caking loads, vibrators 11 are included. 10 scrapers. At the first penetration of the scrapers, the folding parts 13 are lowered and fixed by snaps 14 until the end of unloading of the wagon 25. The vibrators AND are also turned on when the scraper is buried.

After the scrapers are completely buried, the coupling coupling 21 is turned on, the winch 19 and the ropes 18 move the scraped off part of the cargo to the screw conveyors 5. The cycle repeats until the unloading of the car 25 is completely unloaded. After that, the self-propelled carriage 4 moves back and the cycle is repeated for the next car.
