    专利说明:

    The invention relates to a processing device for rail systems in the urban area with a drive, a machining drive and a contouring, rotationally driven and flying on a shaft arranged in a housing machining tool, wherein the machining tool, the housing and the shaft arranged on a chassis and with a Zustelltrieb be adjusted against a rail head to be machined.
    Mobile devices, in particular rail vehicles, are known which have a machining drive, a feed drive and a machining tool for machining track bodies for full webs (WO 2013109945 A1). Due to the high reaction forces occurring during processing, the processing device must on the one hand have a high rigidity and, on the other hand, have a high-performance energy supply, this usually taking place on the basis of diesel aggregates on the highest supply level and hydraulic and / or electrical ancillary units including the associated periphery. The disadvantage of this, however, is that this is associated with a large dimensioning and a high overall weight of the device, so that such mobile processing devices can not be used in urban areas, especially since the local track bodies are not designed for such a high axle load and only limited due to the prevailing infrastructure there Heights are possible. In addition, such devices contribute to an urban environment, especially in subway shafts, unwanted or inadmissible noise and exhaust pollution.
    The invention is therefore based on the object, a device of the type described in such a way that it has such a compact design, to be used for processing rail systems in the urban area both above ground and underground.
    The invention solves this problem by the fact that the machining tool is cup-shaped and frontally with its bottom attached to the shaft, wherein the peripheral surface of the cutting-carrying edge of the machining tool comprises the shaft and the closer shaft bearing at least partially circumferentially. As a result of these measures, the normal force component of the reaction forces occurring during the machining operation can be introduced by the tool into the shaft bearing so that the bending moment load of the shaft and consequently its deflection can be reduced. Because namely, according to the features of the invention an imaginary envelope of the cup-shaped machining tool within a plane perpendicular to the longitudinal axis cutting plane through the closer shaft bearing, can form only a small lever arm between the force application point of the reaction forces on the machining tool and the bearing forces. Characterized in that the shaft is acted upon according to the invention with a lower bending moment, it can be dimensioned correspondingly smaller than in common rail processing devices. This in turn means that an adapted smaller dimensioning of housing, processing drive, chassis and drive is made possible, whereby the size and the total weight of the processing device according to the invention can be reduced overall. The features according to the invention therefore make it possible to use the device in the urban area in the first place. In addition, a better dimensional stability of the machined rails can be achieved by the resulting higher rigidity of the shaft and the resulting lower vibrations and vibrations, which can also prove to be advantageous in the smaller dimensional tolerances of urban rail systems.
    In order to enable a stepless descending the rail with a guide shoe in the vertical direction with a constant force and over a large power range, and to achieve the setting of a defined depth of cut with the lowest possible number of components necessary for this, the Zustelltrieb can be connected via a transmission to the drive and have a hydraulic feed-free electro-hydraulic linear actuator. Due to these features can be dispensed with a central hydraulic unit of the device, as well as on a separate hydraulic tank and the necessary supply lines, whereby the size and the total weight of the device can be reduced. In rail processing, the use of a hydraulic cylinder due to its inherent power density is basically advantageous for positioning a reference point, which is usually defined by a guide shoe, for supporting the machining tool on the rail in the vertical direction and at the same time against a defined contact pressure to press the top of the rail. This ensures a uniform processing of the rail head and surface irregularities can be avoided. Particularly favorable design conditions arise when a hydraulic cylinder, a hydraulic pump, a servo valve and a pressure accumulator can be combined to form a linear actuator, which is equipped with a control block integrated in the transmission housing, so that the most compact design possible. After the wave can be dimensioned smaller as previously and the possibility exists to summarize the feed drive and machining drive to a common drive, which is connected via a corresponding gear with the drive, these features can work together in such an advantageous manner that the space saved and a design-related corresponding outdoor area can be created near the ground to comply with the necessary for the railway operation of the processing device ground clearance.
    Thus, with less total weight of the processing device and the concomitant loss of friction mass enough traction during the machining process is available, the running surfaces of the wheels can
    Have adhesive or friction lining. As a result, the reaction forces arising during the machining operation can be safely transmitted between the rail and the device, so that the device does not slip. According to one embodiment can be provided to compensate for the loss of friction mass in the wheel treads a circumferential groove, in each of which an elastic ring is used, which transmits a portion of Radaufstandskraft on the rail and physically achieved by the material selection of friction partners higher coefficients of friction. This in turn leads to an increase in the transmittable traction forces. With this arrangement, it is possible to still transfer the resulting processing forces with a reduced total device mass safely. In order for the operating device to be able to drive the differently designed rail systems in the urban area, the wheels of the device arranged on the chassis can be transversely adjustable in the direction of a chassis transverse axis for adjusting the track width.
    In order to enable both a horizontal positioning of the machining tool and the wheels, each lateral chassis side may be associated with a separate, connected to the drive via a gear machining drive, a feed drive and a machining tool assembly, the assemblies and the wheels in the direction of Chassis transverse axis for adjusting the track are transversely adjustable. According to these measures not only a Nachfahren the machining tool in the horizontal direction allows, but above all, a pressing force can be applied to the machining device facing sides of the respective rail heads, so that a guide and uniform contouring of the rails can be achieved by the machining tool. In one embodiment, the wheels of the processing device can be suspended on individual axles on the chassis frame in such a way that they can be displaced relative to one another along a carriage which is arranged in the chassis transverse direction and forms a guide. This ensures that the device can be used even with different gauges of rail systems in the urban area. The transverse adjustment of the assemblies can also be carried out analogously to the track
    Width adjustment of the wheels, but independently of these on a carriage arranged on the chassis.
    In order to ensure an energy supply of traction drive, machining drive and feed drive of the processing device, which is no additional source of noise and exhaust gas, so that the processing device can be used advantageously in the urban area, arranged in the vehicle frame of the device electrical energy storage can be provided, via a common electrical Energy distribution system provides the respective drives energy. As a result, conversion losses between two or more different forms of energy can be avoided, thereby increasing the overall efficiency of the energy supply system. Moreover, an electrically powered processing device with regard to their operation in the inner city area has the advantage that, due to the design, there is no exhaust gas pollution and only a low noise development. Nor are this highly inflammable fuels or hydraulic fluids needed, creating a safe operation is also possible in human-frequented urban areas. By a rechargeable version of the energy storage as a battery also occurring in the urban area overhead lines can be used advantageously to its charging, for example, during the arrival or return to the sites. Since the longitudinal forces occurring during the machining operation must be braked by the inventive machining device due to their compact lightweight construction, so that it experiences no acceleration against the machining direction, can also be provided that the traction drive via a controller in response to the forces acting on the machine tool in the rail longitudinal direction and forces in the Braking operation of the traction drive, the released braking energy is returned to the electrical energy storage. According to these measures, an overall higher energy efficiency of the processing device can also be achieved here, since the otherwise dissipated as heat braking energy can be made partially operational again via recuperation.
    In order to increase the energy capacity of the operating device, it is proposed that an additional mobile energy source be coupled on a separate chassis to the processing device for charging the energy storage and connected to the power distribution system. As a result, an increase in the range and the operating time of the device is achieved, wherein both the number of coupled and a supply circuit forming mobile energy sources and their energy form can be chosen arbitrarily. By one or more coupled, mobile energy sources also acting as Radsatzlast on the rail system total mass of the processing device can be increased so that due to the resulting higher traction forces occurring during the machining process in the rail longitudinal direction forces do not have to be braked. Accordingly, so the energy efficiency of the device can be further increased.
