Description

The utility model relates to the field of railway transport, namely to machines for cleaning crushed stone ballast of railway tracks and turnouts.

From the textbook "Machines and mechanisms for track facilities" under. Ed. S.A. Solomonova, M, ed. "Transport", 1984, p. 254-257, fig. 7.30, fig. 7.32 known track machine SCHOM-3U, which contains a frame based on two self-propelled carts, a power plant, a control cabin mounted on the frame on both sides of the machine with the ability to turn and lower one-way cesspool devices, a device for mechanical cleaning of crushed stone and several conveyors for transporting cut and cleaned crushed stone, as well as weeds. The SHOM-3U machine allows cleaning crushed stone or gravel ballast under turnouts and across the entire width of one track.

The disadvantage of this well-known machine is the impossibility of cutting the ballast to a great depth, as a result of which, for the complete removal of weeds, it is necessary to carry out at least two passes of the machine in the same work area, which adversely affects a number of performance indicators and, first of all, on performance.

From the patent of the Russian Federation for utility model No. 164510 according to class. E01B 27/06, publ. 09/10/2016, a ballast cleaning machine is known, consisting of two sections, each of which is equipped with a bar sump device. When these two sections of the crushed stone cleaning machine work together, high productivity and the ability to cut ballast to a greater depth in one pass are ensured, but separate placement of cesspool working bodies leads to an increase in the cost of the complex as a whole and an increase in energy consumption.

From the textbook "Track Machines" ed. S.A. Solomonova, M., Zheldorizdat, 2000, p. 265-269, fig. 7.14 known track machine SHOM-6B, which is selected as a prototype. This machine contains a frame resting on the undercarriages, a power plant, a control cabin, a bar sump device, a device for mechanical cleaning of crushed stone, several conveyors for transporting cut and cleaned crushed stone, as well as weeds.

This known machine does not cut the ballast to a great depth and requires the use of unproductive manual labor when charging and discharging the bar chain under the rail and sleeper grid.

The inventive concept of the authors is to place various known working bodies of track machines on the basis of one section, reducing the cost of its manufacture and expanding functionality.

To solve this problem, the track machine, containing a frame resting on the undercarriages, a power plant, a control cabin, a bar sump device, several conveyors for transporting crushed stone, is equipped with a single-sided chain sump device fixed on the frame with the possibility of turning and lowering.

This implementation of the proposed machine allows to reduce the cost of its manufacture and expand functionality. A one-sided cesspool does not require preliminary removal of crushed stone for its charging and allows you to prepare a place for charging the bar chain without using manual labor to clear the area for its installation.

The proposed technical solution is illustrated by drawings, where

in fig. 1 shows a general view of the track machine, side view;

in fig. 2 is a side view of a one-sided cesspool; in fig. 3 shows the ballast cutting zones by different devices.

The track machine is made in a self-propelled version and cleans and cuts the crushed stone base of the ballast prism without raising the track grid.

The track machine contains a frame 1 based on self-propelled carts 2 and 3. A power plant 4 is located in the rear part of the frame 1. A control cabin 5 is located in the base space of the frame 1 to control and monitor the operation of the machine.

On the frame 1 there is a bar cesspool device 6 with a drive 7 of the bar chain, as well as a device for mechanical cleaning of crushed stone 8, several conveyors 9 for transporting cut and cleaned crushed stone, as well as weeds

One-way cesspool 10 consists of a cesspool 11, for example, double-hinged with blades, which moves in the guide housing 12. The hydraulic cylinders 13 are designed to lower and raise the cesspool 10, and the hydraulic cylinder 14 serves to move the cesspool 11 in the horizontal plane of the housing 12 of the cesspool 11 together with its drive, made in the form of an electric motor 15 and a gearbox 16. The electric motor 17, by means of the gearing of the gearbox 18 and the ring gear 19, makes it possible to rotate the console with the cesspool device 10 by 360 ° to put the chain 11 under the rail and sleeper grid.

The electric motor 20 through a belt drive 21 allows you to rotate the cesspool chain 11 relative to the axis of the chain drive. This function is intended for placing the working body under the rail and sleeper grid.

A characteristic feature of this machine is the preparation of a one-sided sump device 10 for charging a bar sump chain. To prepare the charging site, the one-sided cesspool 10 is lowered, positioned along the axis of the track, the drive 15 of the chain is started, and with the cesspool running, the body 12 is turned towards the axis of the path. In this case, the cesspool device cuts into the ballast prism and thereby cuts the ballast under the rail and sleeper grid. After that, the one-way sump device 10 is returned to the transport position, the machine moves forward until the bar sump chain is aligned with the place where the ballast is cut, where the sump chain of the bar device 6 is charged.

The most important advantage of the combined use of one-way pit 10 and bar 6 pits, along with the preparation of the charging site, is the layer-by-layer cutting of the ballast, which entails an increase in productivity and cutting depth. Section cutouts are shown in Fig. 3. The upper layer of the ballast prism 22 under the rail and sleeper grid is cut out by means of a one-sided raking device 10, which allows the bar chain to cut the lower layer 23 somewhat lower, thereby increasing the depth of the crushed stone ballast cut.

By adjusting the angle of rotation of the cesspool 10, it is possible to change the width of the ballast notch under the rail and sleeper grid without stopping and "recharging".

Thus, it becomes possible to increase the productivity of the crushed stone cleaning machine, expand its functionality, and also reduce its cost.

Since the design of this utility model includes existing components and assemblies that have proven their industrial applicability and efficiency, it can be manufactured and used in industry, that is, it satisfies the patentability condition "industrial applicability".
