RU2634059C1 - Frontal type machine for cutting out soil surface layer - Google Patents

Abstract

FIELD: construction.

SUBSTANCE: front-type car for cutting out the soil surface layer consists of a self-propelled frame, a supporting and rotating mechanism with an arrow and a ground cutting device placed on it, which moves along a conveyor belt onto a rotary conveyor. The self-propelled frame is mounted on the front and rear traveling trolleys on the rail. Between the frame and the pivoting mechanism guides are placed that allow to move the soil cutting device into the front working position and back to the transport position, where from the bottom, on the frame, retractable propellers are placed for autonomous movement of the machine on the soil in places where the rail lash has already been removed are placed.

EFFECT: expansion of geometric parameters of width and depth of cultivated soil grabbing.

Description

A front-type machine for cutting the surface layer of the soil (hereinafter referred to as the front-end machine) refers to the railway field of technology, and specifically to special track machines working with the soil when arranging the railway track.

According to the prior art, a frontal machine refers to a set of devices intended for cutting out a contaminated ballast layer during repair of a railway track, including replacement of a rail sleeper or turnouts.

This proposal is industrially applicable, since when constructing the frontal machine, structural elements known in world technology, methods and techniques were used.

From the information on the level of technology of existing similar machines of the frontal type for removing the surface layer of soil, the “Track Machine” device, RU No. 2376409 of 2009, is known for processing cuvettes of a railway bed, which is used for cutting ballast when replacing turnouts.

This technical solution served as an analogue to the proposed device of the front-type machine.

The design drawback of the chosen analogue is that when replacing the turnout switch for ballast cutting, the machine is put on an adjacent track, closing the train pass. In addition, the closing period is extended to supply fresh gravel also from a neighboring path.

The proposed frontal vehicle has a main course - railway, i.e. on a rail whip, and additional on the ground, due to special tracked or wheel type propellers. This technical solution makes it possible to cut the ballast, being on the "torn" thread of the path. On the site where the old turnout has already been removed, the proposed machine begins front cutting, moving first along the railroad track, and as it moves forward when the rail track ends, movers move out on the ground, providing support for the machine in the section of the track where the rail lash has already been removed . Thanks to this, the neighboring track remains free for passing trains. In this case, the filling of fresh gravel is also possible from a machine of a similar combined stroke, without occupying the adjacent path.

This method will ensure a high cyclic use of track equipment and perform some operations at the same time, significantly reducing the time of the “window” on the track being repaired, in addition, there will be no restrictions on movement along the neighboring track, which at the time of work will be used as a track with a direction in both side.

The technical result when using the proposed design of the machine frontal type for cutting the surface layer of soil is:

- expansion of the geometric parameters of the width and depth of capture of the treated soil;

- the emergence of the possibility of work in places where there is no rail lash;

- Prevention of restrictions on the movement of rail transport on an adjacent track;

- reducing the time of work.

As a result of the technical result achieved, a socially useful effect when using the proposed frontal machine design is the elimination of dangerous factors associated with finding obstacles to traffic on a nearby path, reducing labor costs and the likelihood of injuries during work due to a more rational organization of labor and reducing the duration of the “window” ”, As well as through the use of free paths for moving freight and passenger vehicles.

The technical result from the use of the frontal machine is achieved due to the special design of the device, which in its composition contains:

frame - 1, front undercarriage - 2, rear undercarriage - 3, tracked or wheeled movers - 4, guides for moving to the working position of the soil cutting device - 5, slewing gear - 6, boom - 7, bucket rotor ( or bar chain) - 8, transport conveyor - 9, rotary conveyor - 10.

The technical nature of the proposed design and its device is illustrated by the figure of FIG. 1 (Transport position), FIG. 2 (Operating position), FIG. 3 (Autonomous movement on the ground), FIG. 4 (Ballast mass transfer).

In the proposed design, the frame 1 is mounted on the front undercarriage 2 and the rear undercarriage 3, which, in turn, rest on the rails of the railway track. This design scheme ensures the prompt delivery of the machine to the place of work on the railway track, while fulfilling the requirements for the size of the rolling stock, as the machine is in transport position. On the frame 1 mounted crawler or wheel type 4 retractable movers, which allow, in the absence of a rail lash, to move the machine along the ground, while the undercarriage 2 and 3 are in a locked state. After arriving at the place of work, the machine is moved from the transport position to the working one, for which purpose special guides 5 are provided on the frame. For this purpose, the slewing gear 6 with the boom 7 installed on it and the bucket rotor (or bar chain) located at its end 8 are moved to the front (working) position along the guides 5. After this, the machine begins to cut the ballast while on the rail track. As the machine moves forward, the front undercarriage 2 stops, and the first mover 4 extends and provides support to the ground in front of the machine. Then, when the rear undercarriage 3 moves to the place where the rail lash ends, it also stops, and the second mover 4 extends and provides support on the ground for the entire machine (Fig. 3). To move the cut out part of the soil, a transport conveyor 9 is provided, which transfers the ballast mass to the rotary conveyor 10 (Fig. 4), which can discard it towards the cuvette or along the train axis to an adjacent train car for weeds.

After cutting the ballast, the machine, in the forward direction, is mounted on the rail lash with the front running trolley 2, raising the front mover to the transport position, and then, as you move forward, the rear running trolley 3 is also installed on the rail, while raising the rear mover also in transport position. Thus, the track section for the operation of other machines is quickly freed, ensuring the cyclical use of the track equipment.

The final operation of the slewing mechanism 6 with an arrow 7 and a device for cutting soil 8 moves along the guides 5 in the transport position.
