Description

Description of the invention

The invention relates to a machine for cleaning the rubble base of a rail track, which has its own frame, made with 2 possibilities of movement along the rail track with the help of running mechanisms, and two endless collection chains for receiving rubble from the rubble base, located one behind the other in the longitudinal direction of the machine, cover the corresponding section of the track and are made with the possibility of movement in height and in the lateral direction with the help of drives, as well as transport devices for delivering crushed stone, a screening unit for cleaning crushed stone, a transport device for feeding already cleaned crushed stone and track lifting devices, 710 connected with car frame The invention also relates to a method for cleaning crushed stone.

A similar cleaning machine is already known from (patent OE 4343148 A1, EC 1029167 and BO 240043 AT). This machine has its own frame, made with the possibility of moving on a rail track, and between the running mechanisms located at its ends, there are two collecting chains located directly behind each other. The screening unit is located between both collection chains. While the continuous advance of the machine 72 forwards crushed stone is delivered along the front, first collection chain to the screening unit, with the help of another collection chain, the soil is removed, which serves as the basis for the crushed stone ballast layer. The soil enters the transport device and is dumped, for example, into the next wagon behind. Before dumping the cleaned crushed stone, sand is added to create a protective layer of the ground surface.

From patent EC 714645, a device with four endless multi-bucket lines is known, along which crushed stone is fed upwards and enters the screening unit.

From ER 0629744 B1, another machine is known for carrying out cleaning work in the subway. The crushed stone removed by the layer with the help of the first collection chain is crushed in a stone crusher, dumped on the rail track to create a protective layer of the earth bed and compacted. With the help of the second collecting chain installed on the second frame of the machine, the soil is excavated, which is replaced by a protective layer of earth (3 sheets). Then the track is laid. At the next stage of the work, new crushed stone is poured to create a crushed ballast base.

The task of the proposed invention is to create a machine for cleaning rubble of the specified type, with the help of which an increase in the degree of cleaning is achieved. at

According to the invention, this task is solved using a machine of the specified type, which has the features given in the main claim.

Thanks to such a constructive solution, it is true that, on the one hand, the laying of the rail track for -- a short time for the support of the machine, and on the other hand, it is possible to significantly increase the degree of cleaning, thus avoiding large construction costs. Such significant construction costs would be necessary in the case of placing both assembly chains on one common frame of the machine, since the distance between the two running mechanisms - located at the ends - must be very large in order to be able to ensure the corresponding permissible mobility of the rail track. For this reason, in order to increase productivity, the capacity of the screening plant and the collection chain has been increased until now. With the help of the side seal, it is possible to stabilize the position of the track during the laying of the rails for a short time for the purpose of safety, so that the passage of the running mechanisms located between both collecting chains is ensured without any problems. Other benefits and forms of implementation of the invention are given in other clauses of the formula. c" Further, the invention is disclosed in more detail with the help of an example of implementation presented in the drawings.
