Definitions
- the invention relates to a rail grinding machine according to the preamble of the claims, which is intended for grinding the railroad tracks, in particular the local and long-distance transport network.
- the invention is therefore based on the object of providing a rail grinding machine with means for dust and spark protection which enable the most exact, relief-dependent separation of the grinding space from the environment, do not require any special precautions to prevent fire and which furthermore improve sound insulation. , * Maintenance that simplify grinding tools. According to the invention, this object is achieved by the characterizing features of the first claim. A gradual adjustment must be small steps.
- the means for dust and spark protection are advantageously designed as one-piece or multi-piece blinds which are heat-resistant at least on their inner sides.
- the rouleaus are located on both sides of the grinding machine. The individual pieces of each blind (each blind) are articulated together.
- the inside of the rouleaus can be provided with a flexible layer that protects against flying sparks, or they can consist of one material (light metal, plastic, wood).
- these grooves are guided and provided with rubber aprons at their free ends that adapt well to the relief.
- sheet metal plates With the free ends of the rouleau, which is laterally encompassed by groove pieces, sheet metal plates are connected in an articulated manner, which support the functionality of the rouleau and to which the rubber aprons are fastened.
- the rubber aprons advantageously have heat protection on the inside.
- the height of the blind can be adjusted manually, by actuating switches belonging to electric or pneumatic drives, or automatically.
- each adjustable roller blind is assigned at least one sensor which rotates a spindle via a motor to which the roller blind is fastened and around which the roller blind is wound.
- Fig. 1 is a rail grinding machine essentially in side view and Fig. 2 is a two-part blind in a perspective view.
- a rail grinding machine 10 consists of a grinding carriage 11 and a generator carriage 12, which move with carriages 13, 14 in the direction of an arrow 15 on rails 16.
- Each undercarriage 13, 14 comprises four wheels, two of which are each seated on an axle 17, 18 and of which only the ones in the front are visible.
- Corresponding to the wheels, only the front one of the rails 16 is visible on an associated relief 19.
- At least one track roller 20 is pivotably connected to the chassis 13 for each wheel on each rail 16 and can be placed on the rail 16, only one track roller being shown for reasons of clarity.
- 14 track rollers can also be assigned to the undercarriage.
- each carriage 11, 12 there are four support feet 21, 22 which can be extended and retracted at right angles to the rails 16, only the front of which are visible and which are used to lift the carriages 11, 12 off the rails 16 (during maintenance work) and to put them on the car 11, 12 can be used on the rails 16 (in the event of accidents).
- a driver's cab 23 At the front end of the grinding carriage 11 there is a driver's cab 23, on the bottom surface of which two sensors 24, 25 are attached one behind the other in the drawing.
- two sensors 26, 27 are attached to the rear 121 of the carriage 12.
- the sensors 24 to 27 are range finders acting according to the optical principle or the ultrasound principle, which detect changes in distance from the relief 19 outside the rails 16 and pass them on to a central control unit 28 (FIG. 2).
- roller blinds in the form of blinds 29, 30 and 31 are provided on both sides, of which only those on the side facing the viewer are visible.
- the blinds 29, 3Q are guided laterally in groove guides 50, 51, 52 and the blind 31 is guided in groove guides 53, 54.
- single blind can also be used can be used if they meet the requirements for stability and tightness.
- the sensors 24 to 27, viewed in the direction of travel 15, are aligned with the right and left blinds corresponding to the rails 16.
- the blinds 29, 30 close a grinding chamber 32 in the grinding carriage 11, in which grinding modules 33 belonging to each of the adjacent track rails 16 are arranged on both sides in a regular arrangement and on the suction devices 34 in the upper part with cyclones 35 (as filter systems) and suction fans 36 are connected.
- cyclones 35 as filter systems
- suction fans 36 are connected in the suction devices 34.
- settling tanks 37 are provided with filters for the dust particles in the air flow.
- the dust-free air 39 is released into the environment through a pipeline system 38.
- the blind 31 closes a grinding chamber 40 of the generator carriage 12, in which grinding modules 41 are located, of which those belonging to the rear rail 16 are also not visible.
- the generator carriage 12 contains at least one generator 42 for driving all the grinding modules 33, 41 above the rails 16. Two generators can also be provided, each of which drives the grinding modules via a rail. Cooling and combustion air 44 reaches the generator 42 through ventilation slots 43. Slots are also provided on the rear side 121 of the generator carriage 12, through which the exhaust air 55 of the generator 42 can escape.
- the grinding chamber 40 of the generator carriage 12 is connected by a pipeline 45 to the suction device (s) 34 of the grinding carriage 11, so that this suction device 34 generates a vacuum in the entire grinding chamber 40 between the wheel axles of the grinding carriage 11 and the generator carriage 12 and its dusty air sucks, which is filtered in the settling tank 37 and freed of dust.
- each carriage can also be provided with its own suction device.
- protective aprons 46 are also attached transversely to the direction of travel. In this way it is ensured that, due to the action of the suction devices 34, fresh air 47 only through the narrow gaps 48 and 49 between the blinds 29, 30, 31 and protective aprons 46 on the one hand and the relief 19 on the other hand into the scarf spaces 32 and 40 arrives so that the greatest possible negative pressure is generated in the grinding rooms.
- the grinding mist 61 which arises during the grinding process in grinding rooms 32 and 40 and consists of fresh air, grinding stone residues, rust particles, iron dust and other rail and rail bed impurities is extracted from all areas of the grinding rooms.
- the narrow gaps 48, 49 do not allow the grinding mist to escape because of the large negative pressure in the grinding spaces 32, 40, although the grinding residues are associated with considerable kinetic energy due to the grinding process. This energy is considerably reduced for the grinding particles by mutual influences and by braking on the blinds 29, 30, 31 or grinding protection aprons 46 and other limitations, so that the grinding residues, like the other components of the grinding mist 61, are caused by those in the grinding chambers 32 and 40 Vacuum follow the suction of the suction or fall due to their mass on the superstructure.
- the dense blinds 29, 30, 31 serve not only to protect against dust and noise but also to protect against sparks. Flying glowing metal shavings cannot leave the track area through narrow gaps 48, 49 and therefore give no cause for fire.
- the use of special water spray systems is therefore basically unnecessary.
- the blinds 29, 30, 31 also prevent moisture (rain or water spray) from coming into contact with the aggressive grinding residues. Finally, the uncomplicated operation of the blinds 29, 30, 31 enables easy access to the grinding modules 33, 41 during maintenance work.
- the groove guide 51 is designed on both sides, so that both blinds 29, 30 are guided with their mutually facing sides in the same component 51.
- Each of the guides 50, 51, 52 has corner aprons 501, 511, 521 at its lower end.
- the blinds 29, 30 are fastened to a spindle 56 which is rotatably mounted in a box 57 about an axis XX.
- the rotation of the spindle 51 causes an electric motor 58 (for example a rod motor) which, depending on the signals from the sensors 24 to 27 from the control unit 28 is rotated depending on the direction.
- the groove guides 50, 51, 52 ensure not only an exact, but also a relatively tight guidance of the blinds 29, 30.
- a metal plate 59 (made of aluminum) is articulated at its free end 291, 301, with which a heat-resistant apron 60 is screwed.
- the apron 60 can be made of a heat-resistant, flexible plastic or of rubber, which is provided with a non-combustible layer on the grinding chamber side (sandwich shape).
- the blind 31 is designed, stored and driven similar to the blinds 29, 30.
- a motor is provided on the left side L and on the right side R of the rail grinding machine 10 for each blind spindle, which rotates the blind spindle assigned to it in a direction-dependent manner.
- the electric motor 58 can also be switched on and off manually depending on the direction. Finally, it is also possible to manually rotate the spindle 56 by the required amounts depending on the direction.
