Description

Technical field

The invention relates to a remediation mechanized machine which is intended for remediation work on a railway substructure, with the possibility of using gravel obtained from the railway superstructure, and without laying the rail grate.

The state of the art

With the increasing demands on rail transport, the demands on the superstructure are increasing. In order to increase its load-bearing capacity, reinforcing gravel layers are inserted between the ground plane and the gravel bed, geotextiles are optionally inserted between the gravel layer and the earth plane, the unbearable layer of the earth plane is removed and replaced with a more bearing material.

These works are currently carried out either with conventional earthmoving machines after laying the grate or with special machines, eg. type PM 200. The first method requires, as has already been said, the dismantling of the grate, the subsequent carrying out of the remediation work and finally the laying of a new grating. Although this method does not require any special machines, it is very time-consuming and very expensive due to the disassembly and refitting of the grating, notwithstanding the losses caused by the long-term interruption of the railway traffic in the section.

Used special remediation machines use a mining mechanism, which unloads the old gravel bed at the same time with an unbearable layer of the ground plan. Although these machines do not require disassembly of the grate, it is necessary to interrupt the track before the work begins. Today's special remediation machines are very large devices that do not allow other technological work, such as barking, undercutting, etc., directly behind the machine. In addition, the excavated gravel is mixed with the soil and cannot be reused, so the excavated material needs to be loaded onto the wagons while supplying the machine with a new gravel to replace the excavated gravel.

SUMMARY OF THE INVENTION

These drawbacks are eliminated wholly or at least to some extent by the mechanized repair machine according to the invention. The remediation machine is preferably formed by a two-wheeled four-axle vehicle without its own traction drive, which is connected to the traction unit and other elements of the remediation complex. It is an object of the invention that the machine is provided with two movably mounted extraction mechanisms, a first for the extraction of gravel bed material and a second for the excavation of a ground plane material. The machine is further preferably provided with a gravel separator which on one side removes unwanted large objects, e.g. by means of a sieve with large meshes, and on the other hand it removes admixed small impurities such as ground, sand, etc. These large objects and small debris are discharged to the waste conveyor path as well as the material extracted by the second extraction mechanism. The cleaned gravel can be used directly to backfill sleepers or can be stored in separate wagons for further use. Simple adjustment, eg. however, by separating the sorter, by spreading the shield above the waste conveying path, etc., it is possible to introduce a full extraction mode with the removal of all the excavated material.

The advantage of the rehabilitation mechanized machine according to the invention is, in particular, the possibility of re-using the cleaned gravel, because, due to the smaller dimensions of both extraction mechanisms, there is no need to interrupt the rails before starting work. The smaller dimensions and weight of the machine according to the invention mean substantially lower purchasing and operating costs. Given that in the remediation complex, the waste collection wagons as well as the gravel feed can be placed in front of the remediation mechanized machine itself, it is possible to perform almost immediately other technological operations connected with the operation of the rails. This results in a significant reduction in the required closure time.

It is preferred that the first extraction mechanism allows the material to be extracted up to a depth of 0.6 m below the bottom surface of the sleeper and the second extraction mechanism is capable of excavation to a depth of up to 0.5 m below the level of the first extraction and possible underlay of the geotextile.

Part of the invention is also a distribution device, which allows mainly the underfilling of sleepers in the area outside the rails and, in the case of a sufficient quantity of gravel, also the delivery of this gravel into the space between the rails. In the case of a further excess, the distribution device allows the gravel to be discharged into the gravel containers and the like. The splitting device is preferably mounted on a satellite towed by a machine on rails.

Advantageously, the remediation mechanized machine is provided with a device for conveying gravel from the attached storage vehicles and a device for forming a compacted gravel layer. It is advantageous even if the remediation mechanized machine is equipped with a device for laying geotextiles between the gravel layer and the ground

DETAILED DESCRIPTION OF THE INVENTION

The remediation machine in FIG. 1 is moved on two bogies 94, on which a frame 90 is supported, which carries the equipment necessary for the actual operation of the machine, the working cab 92 and the cover of the aggregates 93.

The extraction mechanism 11 consists of two troughs 10 in which the extraction chain is guided. The troughs 10 are suspended in a swinging frame 11 with a chain drive which extends into the hopper 12, the bottom of which flows into the gravel separator 30. This extraction mechanism loads the gravel bed.

The extraction mechanism H 2 again consists of two troughs 20 in which the hauling chain is guided. The troughs 20 are suspended in a swinging frame 21 with a chain drive which extends into the hopper 22, the bottom of which is connected to the waste conveyor I 51. This extraction mechanism loads part of the ground plan.

The sorting circuit 3 is primarily formed by a sorter 30, which is mounted in a pivotable manner in the machine. The upper screening area is extended by a screen 31 for separating large objects. The sieve fractions and large objects are led to the waste conveyor I 51 by means of chutes. A hopper 32 forms an integral part of the separation and storage circuit 4 in the front part of the separator.

The main element of the cartridge circuit 4 is a satellite with a distributor 41 and a hopper 42 of the container 42. In the transverse section of the distributor (FIG. 2), a hopper of a sorter 32 is shown in which a shield 33 is located. By expanding the shield 33, the gravel is directed to the waste conveyor I 51, i. j. "Full load" mode of operation. The actual distribution device is placed on the frame of the satellite 49, which is moved along the rail by rolls 48. Preferably the gravel is dosed under sleepers from the outside of the rails, the dosing can be influenced by the flap 46. The excess gravel is poured into the central part of the distribution device 41 If it is desired to place the gravel behind the sleeper heads, the flap 44 is opened and after the slip 45 the gravel is discharged behind the sleeper heads. This will create a new gravel bed 101.

In the cross section of the gravel container of FIG. 3 shows again the hopper of the classifier 32 with a fixed shield 34. The actual hopper of the container 42 with the shutter 47 is again placed on the frame of the satellite 49 with the traveling rolls 48. The gravel container together with the distribution device allows the necessary rail backfilling as necessary. The waste conveying path 5 is formed by a waste conveyor 151, a slanted conveyor from behind II 52 and a rotary conveyor 53 mounted on the frame 90 by means of a turntable 54.

In order to ensure the necessary position of the track for work, the remediation mechanized machine is equipped with a lifting and routing system 6 consisting of two lifting devices, namely the lifting device I 60 located in the gravel bed lifting area and the lifting device II 61 located at the creation points. gravel layer 102.

In order to form the gravel layer 102, a gravel conveyor 7 is provided in the sanitation mechanized machine. It is formed by its own conveyor 70 having a hopper 71 at the inlet end for receiving the gravel supplied from the stack of wagons. A dispensing hopper 72 is disposed at the outlet end of the gravel conveyor, which displaces the rails on its own trolley during operation. Dosing is accomplished by varying the width of the dispensing hopper outlet slot 72.

The metered gravel is processed under the rails by the diffusion and compaction system 8, which consists of a diffusion device 81 with the possibility of adjusting the desired layer thickness and a compaction device 82. It also allows insertion of the geotextile 103 between the ground plane and the hake layer by the diffusion device 80.

Figure 5 shows a further possible embodiment of the remediation mechanized machine, in which, in addition to the removal of waste and the supply of gravel at the front end, the discharge of the already cleaned gravel and the supply of a new gravel at the rear end of the machine are solved. In this embodiment, the cleaned gravel conveyor path 9 is formed by the conveyor 95, formed by the conveyor 95, the conveyor 96 positioned in the machine after sliding by rolls, and the guide 97, and the rotary conveyor 98 cleaned gravel located in the machine by the rotating device 99. It is constructed with a movable bottom 37 and sidewalls 38. The cleaned gravel is conveyed from the sorter 30 to a conveyor 95 which passes under a chute for separating large objects and a hopper of a second extraction mechanism 2. The gravel from conveyor 95 can then be supplied to either conveyor 96 or The choice of these two options is effected by means of a sliding guide for accommodating the conveyor 96 in the guide 97. From the conveyor 96, the gravel can be supplied either to the reservoir 39 or to the attached storage vehicles. This option allows the rotary conveyor 98 to be rotated either to a position where it transports the gravel to the hopper or to the attached bunkers. In the case where the cleaned gravel is delivered to the bunker wagons, or if refilling is required, a new ’pebble from the attached bunker wagons may be delivered to the bunker 39. The gravel is in this case supplied by the conveyor of the container car as shown in FIG. 6th

In FIG. 4 shows the connection of the remediation machine according to FIG. 1 in the remediation complex. machines for further technological work can be included. In FIG. 6 shows the wiring of the machine of FIG. 5 with the gravel container wagons attached, as well as possibly storing the cleaned gravel and refilling the new gravel into the container 39. The new gravel is supplied to the container 39 by the container truck conveyor.

It goes without saying that exemplary embodiments are not the only possible uses of the invention. The machine according to the invention can be made up of a plurality of mining equipment, the transport and deposit of gravel, gravel and waste can be performed differently than described, the remediation mechanized machine can be disassembled, e.g. on several vehicles, it may be equipped with a power supply, or it may only be connected to the power supply, etc. However, it will always be an advantage of the invention since its object is to extract the gravel layer capable of being cleaned and to clean it directly in a sanitation mechanized machine and to use the cleaned gravel in the formation of a new gravel bed.
