Device for removing, cleaning and renewing railway ballast

The invention relates to a device for removing, cleaning and renewing iron gravel.

Devices for the repair and renewal of railway bedding are machines that take up the old ballast, Put these seven and the ballast stones back on the track bed, those of too large and too small particles and cleaned of dirt, with the replaced stones leveled and tamped down to the desired extent during a step called "leveling" and taking the sifted-out remainder into a container vehicle or is unloaded to the side of the track bed.

From FR-PS 1.526.948 a device has become known, which is essentially in connection with free tracks was developed, i.e. with tracks that are not located in the area of stations and switching points. This device lifts the rails and also the sleepers so that the bucket chain can reach under the rails, the ballast

is put down again behind the bucket plant and spread out, before the rails are lowered again. The machine therefore runs on the rails themselves, but in front of them in places and behind the workplace for removing, cleaning and renewing the ballast.

It goes without saying that such a machine is nearby of switching points and generally in stations in which the work space is limited, is not suitable. In such In some cases it is necessary to work the rail and ballast manually. For such a case it has been suggested To use cup cleaners of a known type, i.e. those that are mounted on caterpillars and a bucket elevator at the front end have or bucket works, in particular a conveyor of the cup type, which is arranged on a tower that is around a vertical axis can pivot by the desired width. These bucket works can have the removed material sideways or unloaded in various transport vehicles. You can even clean the gravel and remove the usable portions of the Return ballast, but in such a case the ballast is generally deposited behind the machine, i.e. behind the endless drive or the caterpillars. A number of disadvantages result from this.

The first disadvantage is that the machine must run on the rail bed from which the ballast is being removed i.e. on a relatively loose surface. The rails can become very irregular in the track bed dig in, especially because of the bucket conveyor

809809/0691

often pivoted to the left and right and the chassis performs appropriate tilting movements and therefore a Burrowing is more likely at certain points than at others, moreover it is then because of the lack of Reference points quite difficult to level the gravel.

In certain machines of this type, and in particular in the machine described in FR-OS 7.520.742, been proposed to deposit the ballast in front of the machine between the bucket chain and the endless drive. One such a machine has a chassis carried by a crawler track and a bucket mechanism at its front end or carries a bucket conveyor that can be pivoted horizontally about a vertical axis and one carried by the chassis Separating and sorting device for sorting out too large and too small particles and dirt and for removing this sorted out material and for the subsequent re-laying and spreading of the cleaned ballast the track bed behind the bucket conveyor, but in front of the tread, the device for spreading, the is carried by the machine, which thus acts on the ballast that has been moved between the bucket elevator and the drive is arranged. The conveyor belt that returns the cleaned gravel behind the bucket conveyor stores, is arranged for the purpose of rotation at its rear end about a vertical axis relative to the chassis of the Machine is fixed and arranged in front of the vertical axis for the horizontal pivoting movement of the bucket conveyor and on a

_80 9.8 09/0691

Point in the middle of its length under your chassis of the bucket conveyor for horizontal pivoting movement about its rear vertical axis is suspended to the horizontal Pivoting movement of the bucket conveyor to follow its own vertical axis, so that the cleaned gravel is deposited essentially over the entire width of the zone swept over by the bucket conveyor.

Although this training reduces the disadvantages of the known machines that run on the track bed that of his Ballast is freed, on the other hand, such a machine has the disadvantage that it works on the newly spread ballast runs, which is shifted by the swiveling movements of the crawler tracks, and it is also necessary to use other means to create a start-up bed to train or auxiliary bed and the elements, such as the old gravel, earth or too small particles, which from the bucket elevator or the screening device can fall down, can fall back on the new ballast.

The object of the present invention is therefore to provide a device for removing, cleaning and renewing railway ballast to improve so that the disadvantages of the known devices or machines do not occur.

This object is achieved by the invention specified in claim 1.

The apparatus for removing, cleaning and renewing railway ballast according to the present invention comprises a an endless drive mounted chassis that carries a bucket mechanism, which is mounted on a tower so that it is around a lower

both of which have the same vertical axis but different radii. A pair of rollers 15 runs on each of these rails and 16, which carry the support frame 17 of the bucket conveyor, whereby this frame is thus arranged for rotation about the axis 12, in that the drive takes place via chains, not shown, which run on the rails 13 and 14 or in another known manner. On the support frame 17 arms 18 are articulated on their other End at 19 are hinged on the frame 2o of the bucket factory. These arms 18 form with the support frame 17 and the frame of the bucket works 2o two lateral parallelograms, with which lifting devices 21 cooperate, relative to the working plane of the bucket elevator to raise or lower the chassis 1 of the device.

As shown in greater detail in FIG. 6, the chassis of the device, represented by its longitudinal rails 22, according to a preferred embodiment has at least two transverse rails 2 3 which are arranged pivotably about the ends of the longitudinal axes around the transverse rails 2 5 of the chain frame 6, the transverse inclination of the frame 1 being adjustable with the aid of lifting devices 26 which act on the cross rails 24 and 25. In this way, the chassis 1 can be kept horizontal despite the incline of the track bed. The vertical plate 1o is mounted on a transverse plate 27 at the rear end of the chassis 1 about a longitudinal axis 28 and its transverse inclination is adjustable by means of lifting devices 29, which act between carriers rigidly 1o connected to the rails 22 and fixed to the plate Centers or centering points 3o are connected. This makes it possible to reduce the transverse inclination of the working level of the bucket plant

809809/0691

-1O-

and to adjust the leveling device relative to the horizontally held chassis 1 and thus the new inclination of the rail to adjust.

In the particular embodiment of the carrier of the bucket mechanism shown in FIG. 2, this carrier has on his lower end two lateral arms 18 ', which at 31 on the support frame 17 are articulated and have an axle 32 which is equipped with vehicle wheels 33 for railroad tracks and on The articulation point 19 of the arms 18 is attached to the chassis 2o of the bucket conveyor via lateral lifting devices 34. On the axis 32 articulated arms 35 are arranged at 36 on the outer ends of transverse axles which are connected to the lower return sprocket axle of the bucket elevator coincides and is rigidly connected to the frame 2o of the bucket elevator. These arms 35 extend backwards, in order to carry a transverse rail 37 on the other side of the bucket elevator run, which forms the support frame of the leveling device. The arms 35 can be rigidly connected to the arms 18 'via removable spindles 38 will. In their working position, the spindles 38 are held in position and lifting devices 34 are not in operation, The working height of the bucket works can be adjusted with the aid of the lifting devices 21. For use on a railroad track the spindles 38 are removed and the hoists 34 are extended to bring the wheels 33 into contact with the rails to bring and the bucket elevator and the leveling device and the chassis of the bucket elevator and the leveling device tend to go through in the gauge so that they are raised above point 19.

On the other hand, the arms 35 carry lateral frames or brackets 39, on which pendulums 4o, which are provided with rollers 41, the run on inside rails 42, frames 43 of the side conveyor belts 44 are arranged. At the front end, the frames 43 are held by the support frame 17 so that they are the same Take the same direction as the bucket conveyor. They have a double hopper 45, the upper opening of which has the shape of an arc and which extends over two chutes 46 onto the conveyor belts emptied. The two filling hoppers are separated by a rabbit 47, which can be moved with the bucket elevator by 50 on both sides of the longitudinal axis is, in front of which the conveyor belt 48, which ensures the return of the good ballast, delivers its load. The conveyor belts 44 give off the cleaned ballast at the rear end of the rail 37. With such a device, the cleaned ballast between the longitudinal plane of the bucket elevator and the axis of the railroad track when the bucket elevator is around the vertical Axis 12 has rotated once in order to ensure the production of the ballast layer over the entire width of the bed cleaned with the help of the Eiroerwerkes.

The bucket conveyor or the bucket elevator itself is common Art, called retro, and the cups or buckets 49 that hold the ballast at the end of the circular arc they wrap around the lower sprocket describe, have picked up, transport the load upwards along the lower route to be in a hopper 5o unloaded, which in turn unloads onto a conveyor belt 5o, which transports the load to a sieve system 52, which with an Ab Provide clearing tape for the oversized and undersized particles 53

and that is of known training and therefore will not be described further here. A conveyor belt 54 is transported the cleaned ballast back to the conveyor belt 48. The buckets or cups 49 point according to a more detailed in FIG embodiment shown on a base part 55, which is on wheels 56, which is carried by the chassis 2o, the various base parts by means of connecting means, not shown are connected to one another, forming an endless chain that passes chain wheels, at least one of which is the drive wheel. On the base part, side walls 57 are fixedly arranged, which have a transverse guide vane 58, which is usually is provided with teeth. A pivotable wall 6o is articulated at 59 at the rear end of the guide vane. The shovel is also fixable. The bottom wall 61 of the bucket or beaker is hinged at 62 on the base part about a transverse axis and has flanges 63 rigidly connected, the wheels 64 carry. In the embodiment shown, the free edge has - but not necessarily - Hooks 65 that catch the rear edge of the plate 6o. The wall 61 could also consist of a rigid rubber sheet be made, at least along the closing edge, in order to avoid breakage if a stone is pinched along the edge. In the latter case, the flanges 63 form hinged levers at 62 which support said plate. Wheels 64 run at least during a pass that brings them back via the hopper 5o, on rails 66 fixedly connected to the frame 2o, in such a way, that the wall 61 is held in a closed position (bucket or cup 49a, FIG. 5). If the wheels 64 are out of contact with the slide

809809/0691

-13-

nen 66 arrive, the wall 61 (bucket 49b, Fig. 5) opens to to deliver the load into the hopper 5o. Thereafter, the bucket closes during the downward movement (bucket 49a) either by the Gravity or by the running of the rollers 64 on the rails 67, which are similar to the rails 66.

The pile of gravel 68 that has been unloaded by the conveyor belt 44 is spread and leveled through a leveling bucket 69. This leveling bucket 69 is articulated about a vertical axis (not shown) on one Horizontal rail 7o attached, guided by vertical axes 71, which are displaceable in the support rail 34. The height adjustment of the leveling shovel is accomplished with the aid of a lifting device 72. Maintaining the planer shovel 69 in the longitudinal plane of the bucket elevator is effected with the aid of springs which allow the shovel to be withdrawn when a abnormal resistance should occur.

As soon as the device moves forward, the bucket elevator 2o removes the ballast over a predetermined width according to its periodic pivoting movement about the axis 12, wherein the pivoting through an angle of 5o ° takes place on both sides of the axis of the railroad track. The cleaned gravel becomes returned at 68 behind the bucket elevator and spread out with the help of the leveling shovel 69.

The invention thus relates to a device for removing « Cleaning and renewal of railway ballast on a track bed, which has a chassis that is mounted on a crawler and has a bucket mechanism at its rear end "that denotes
