SU196926A1 - RAILWAY MACHINE FOR CLEANING BROAD CONSTRUCTION UNDER THE WAY TRACK - Google Patents

Description

Railway machines are known for cleaning contaminated ballast under a track grid. These machines have two symmetrically located cesspools in the form of a spatial articulated endless chain with cutting blades, a ballast cleaning device, a tank for cleaning, a wane, an ebn, and a conveyor for waste disposal.

Known machines, giving good quality of rubble cleaning, at the same time, do not allow to completely mechanize this process in all parts of the railway track. Most of these machines can only work on the hauls, some - on the hauls and stations, but none of them makes cleaning w, ebn under switches, near platforms, and so on.

The proposed machine differs from the known ones in that each cesspool body is mixed together with the drive in the wing of the machine pivoting about a vertical axis with the possibility of placing a chain under the sleeper grid to the width of the track. The machine can clean the ballast ballast not only on the tracks, but also on the stations at the platforms and under the turnouts.

vertical lines and in plan, which ensures continuous cleaning of two layers of ballast across the entire width of the ballast layer simultaneously between stations, and each grab body can be fixed along the machine axis and across it. This allows the ballast to be cleaned under the switch by a non-switch by passing from the right side of the left side.

The device for cleaning ballast is expediently made in the form of a screened screen along the axis of a mesh belt that moves along curvilinear guides, and the ballast is freed from contamination by centrifugal force. Purified rubble is discharged into the bunker, and the waste is removed out of the way.

A waste conveyor can be mounted pivotally on a vertical carriage pox, which allows the waste to be thrown to the side of the machine or installed in a trailer car and set the conveyor into a car envelope along the transport axis.

The machine is self-propelled, so the cleaning work is done without the use of a locomotive.

On frame 1, supported by two self-propelled two-axle bogies, a cesspool device is mounted, which includes two identical, symmetrically located but on the sides of the frame, two curtain taps 2 with scrapers 3. Chains move in rails 4 along undercut ibju 5 using a vertical tubular axis 6 to pivot around the vertical column 7 wing 8.

In the center of the frame along the longitudinal axis there is a screen made in the form of a mesh belt 9, moving in curved guides 10 and driven from the electric motor 11 through a gearbox or chain drive.

In order to receive and distribute the cleaned rubble, a bunker 12 is mounted with two interconnections located in the zone of rail threads. A protective device in the form of a two-sided roof racks 13 is fixed under the branch pipes above the rail yarns, preventing the gravel in the gap between the rim 14 and the frame rail 15. A dispenser in the form of a shield 6 and wing flaps 17 is installed on the frame.

Behind the mesh belt there is an inclined conveyor 18, behind which a conveyor 19 is installed over the frame of the machine to remove waste. The conveyor belt removes waste off the track to the right or left side or feeds it into the gondola attached to the machine.

To install this conveyor in one working place or transport position, it is made rotatable around axis 20 by 360. The rotation conveyor can be moved in a horizontal plane across the maschine using the carriage 21 along the guides 22 with a special mechanism 23, which ensures compactness of the machine.

The body 24 is mounted on the frame of the machine, and a power station and control panel are located in the cohort.

To clean the gravel ballast on the stretch, the cesspools are placed under the path on both sides of the mashina, one of which is displaced but vertical and relative to the other, due to which the ballast is cut vertically in two layers.

Driving to the place of work and the continuous movement of the machine during operation is carried out by the help of self-propelled carts.

The rubble is cleaned as follows. The wing 8 with the sump is opened and lowered by an amount sufficient to remove the full layer of crushed stone ballast. Then the sump is turned and its lower part is turned under a path, perpendicular to its axis. In the process of turning, the scrapers 3 remove the rubble from the sub-path, freeing up space for the sump.

the grids and scrapers 3 are lifted onto the screen 9 of the screen.

Under the action of centrifugal force, the crushed stone is cleared of dirt when the curved guide 10 passes through the tape. The cleaned crushed stone is dumped into the bunker 12, from where it is poured out along the two pipes, located in the area of the rail threads. When the mashine moves, the cleaned rubble is distributed throughout the width of the path with the help of a dispenser.

The dirt, separated from the rubble, is ejected by centrifugal force through the mesh of the mesh screen onto the inclined conveyor 18, which lifts it and throws it onto the belt of the rotary conveyor 19. Depending on the position in which the novorotny transnorter is installed, the waste is thrown away putn or cargo ts to

gondola cars attached to the car from the side of the conveyor.

When cleaning rubble under switches, the maschina makes two passes: the first with the suction device on the right side and the exit in one direction, and the second with the suction device on the left side and an exit in the direction of the arrow the opposite side.
