Abstract

The crushed stone cleaning machine belongs to the field of railway transport equipment, is intended for servicing the infrastructure of railways and contains a frame resting on undercarriages, a power plant, a control cabin, rotary working bodies mounted on the frame on both sides of the machine, a device for mechanical cleaning of crushed stone, several conveyors, as well as a bar sump fixed to the frame.

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 "Track Machines" ed. S.A. Solomonova, M., Zheldorizdat, 2000, p. 260-271, fig. 7.11, a rotary chip cleaning machine SHOM-6R is known. This machine contains a frame resting on undercarriages, a power plant, a control cabin, rotary working bodies mounted on the frame on both sides of the machine, a device for mechanical cleaning of crushed stone, several conveyors for transporting cut and cleaned crushed stone, as well as weeds.

The SHOM-6R crushed stone cleaning machine is not able to remove crushed stone under the sleepers, therefore, when cleaning crushed stone, the ballast prism is used in conjunction with the second section SHOM-6B, (see Fig. 7.14 of the same source of information), which is equipped with a bar sump device.

The SHOM-6B crushed stone cleaning machine was chosen as a prototype and 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.

When these two sections of the crushed stone cleaning machine work together, high productivity is ensured, but the separate placement of the rotary working bodies and the bar sump chain leads to an increase in the cost of the complex as a whole and an increase in energy consumption.

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

To solve this problem, a crushed stone cleaning machine containing a frame resting on 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, is additionally equipped with from the longitudinal axis of the machine by rotary working bodies. This implementation of the proposed machine allows to reduce the cost of its manufacture and expand functionality.

The claimed technical solution is illustrated by drawings, where: in Fig. 1 shows a general view of the crushed stone cleaning machine, side view; in fig. 2 - ballast cutting zones by different devices.

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

The crushed stone cleaning machine contains a frame 1 resting on self-propelled carts 2 and 3. A power plant 4 is located in the rear part of the frame 1. To control and monitor the operation of the machine, a control cabin 5 is located in the base space of the frame 1.

The frame 1 also has a rotary working body 6, consisting of two multi-bucket rotors located on both sides of the longitudinal axis of the machine. Rotary working bodies 6 are capable of cutting crushed stone behind the ends of the sleepers from the side of the curb and between the tracks, which makes it possible to prepare a place for charging the bar cesspool device 7 for the sleepers and to divide the ballast prism into cutting zones (see Fig. 2).

The crushed stone cleaning machine is equipped with a device for mechanical cleaning of crushed stone 8 (screen), based on sifting the weed through the openings of the “sieve” of the device.

In the middle part of the frame 1, there is a device for distributing clean crushed stone 9, by means of which it is possible to return crushed stone to various areas of the track (ends of the sleepers, the area between the rails).

Also, the machine is equipped with a system of conveyors 10 transporting crushed stone and weed in sections. At the rear of the machine there is a rotary conveyor 11, which has the ability to eject the weed, both to the side of the road and into a special rolling stock.

Owing to a set of working bodies (rotor, bar squeegee) the machine makes it possible to carry out divided cutting of ballast according to the zones shown in Fig. 2. Due to the cutting of the ballast at the ends of the sleepers, the load on the cesspool 7 is reduced, which makes it possible to increase the operating speed of the machine.

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".

Claims (1)

A crushed stone cleaning machine containing 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, characterized in that it is equipped with mounted on the frame on both sides from the longitudinal axis of the machine by rotary working bodies.
