    The invention relates to a device for machining surfaces comprising a cutting disc, which is set in rotation by means of a rotary drive, according to the preamble of claim 1.
    The cutting disc is, for example, a milling or grinding wheel used for machining wall, floor or ceiling surfaces, wherein a disc surface is guided parallel to the working surface and pressed against the surface to be machined. It is known to manually guide cutting discs for processing these surfaces in order to remove material layers from these surfaces. Work of this kind is exhausting and tedious and requires long working hours, since usually only about one square meter per hour can be processed by human effort. If the surfaces to be treated also contain contaminants, for example in nuclear power plant areas where the areas of ionizing radiation or contamination by unstable nuclides have been exposed, workers must wear protective suits which make the work even more difficult and dangerous. In particular, the processing of ceiling surfaces can be accomplished only with great effort. In addition, the removed material represents a dust load, which also contaminates the interior air of contaminated areas by contaminants. Covers and exhaust devices would in turn increase the overall weight of the cutting tool and thereby require even greater effort.
    Although it would be conceivable to automate the machining process by the cutting tool mounted approximately on guide rails and the like and remotely controlled from a safe distance, however, requires the installation and constant repositioning of the guide rails a time, which offers no time advantage over total dog work.
    It is therefore the object of the invention to accomplish the machining of surfaces by means of cutting tools in such a way that not only increases the safety and the manual effort of the work is reduced, but the processing of the surfaces can also be done faster than with manual processing.
    These objects are achieved by the features of claim 1. Claim 1 relates to a device for machining surfaces comprising a cutting disc which is rotated by means of a rotary drive, wherein according to the invention it is provided that the cutting disc is rotatably mounted on a first end of a pivot arm, the second end of a carriage is rotatably articulated, wherein the rotary drive for the disc, and a pivot drive for the pivot arm on the carriage or on the pivot arm are arranged, and the carriage is movably arranged on a carrier in a direction parallel to the disk plane feed direction.
    The invention thus provides, on the one hand, a carriage which is movably arranged on a carrier and, on the other hand, a swivel arm, via which the cutting disc is connected to the carriage. The carriage allows remote control of the cutting disc along the carrier, reducing the workers' effort and increasing their safety, as they no longer have to be in the vicinity of the surfaces to be processed. The processing speed is increased significantly by the inventively provided pivot arm, as in the successful positioning of the carrier by pivoting the pivot arm, a larger area can be edited. In addition, due to the pivoting of the disc can be processed as wall surfaces and surfaces that are covered in horizontal projection from the carrier by the disc is pivoted in the space between the carrier and the surface to be machined. Furthermore, corner areas of interiors are also better accessible by means of the device according to the invention. The applicant's first experiments have shown that the removal rate, including the mounting of the carrier, can be increased to about twenty square meters per hour, and thus a twentyfold increase over the conventional,
    ·· * · «··« · «··« · # represents manual processing speed. Furthermore, the driving power of the cutting disc can be significantly increased, namely currently up to about 22 kW. For reasons of safety at work, hand-operated machines usually have drive powers of less than 1.5 kW.
    Due to the inventive feature that the pivot drive and the rotary drive are arranged on the carriage or on the pivot arm, a functional, modular unit is created, which can be easily arranged on different carriers. It is advantageous if the feed motor for the movement of the carriage is arranged in its Vorschübrichtung along the carrier on the carriage, although it is also conceivable that the feed motor is arranged for this purpose on the support and via actuators such as tensioning belts and the like with the Carriage is connected.
    It is preferably proposed that crossbeams are provided on which the carrier is movably arranged in an adjustment direction parallel to the slice plane and perpendicular to the feed direction. In this way, the disc is guided two-dimensionally adjustable in one plane, so that with a single installation of the carrier and cross member an entire floor, wall or ceiling surface can be edited. The cross members may be part of a scaffold, which is positioned free standing above, in front of or below the surface to be machined, or they may be mounted on the surface to be machined.
    In order to compensate for unevenness and to preserve the disc is further preferably provided that the disc is resiliently mounted on the pivot arm. Furthermore, it is proposed that the disk is movable by means of a controllable pressing unit in a direction perpendicular to the disk plane pressing device. The contact pressure of the pressing unit is preferably infinitely controllable, the contact pressure defining the milling or grinding depth together with the feed speed. A particularly advantageous embodiment is given here, when the carrier is arranged to be movable on the cross members by means of cross member carriages, and the pressing unit is firmly connected on the one hand to the cross member carriage, and on the other hand to the carrier. In this way, the carrier is moved in a direction perpendicular to the disk plane pressing direction and thus the disc, wherein the pressing unit is supported on the cross member.
    Since the disc is motorized guided on the carrier, it can also be larger in diameter and therefore heavier, since the manual effort is no longer a limiting factor. Furthermore, the disc may be provided with a cover which is closed at its, the pivot arm-facing side, and at its, the pivot arm facing away from the side, wherein the cover has a suction device. Removed material is thus sucked controlled and therefore charged neither the workers, nor the indoor air. To make the cover of the disc during the processing of a surface denser, it can be provided that the surrounding the peripheral portion of the disc cover of the cover elastic shell elements has, which protrude in the axial direction of the disc on the, the pivot arm facing away from the disc surface. If the disk is pressed with this disk surface to the surface to be machined, thus apply the elastic mantle elements of the cover to the surface to be machined and produce around the disc a largely sealed area.
    In order to quickly dissipate the removed material, it is further proposed that the disk has apertures distributed over the disk surface whose side edges are oblique. In this way, a suction effect is achieved, so that the removed material can be fed through the apertures quickly a, preferably centrally arranged on the cover suction device. It is advantageous to provide the cover with a tangentially projecting intake for ambient air. In this way, an air flow is generated within the cover, which initially runs tangentially from the intake, starting in the outer peripheral regions of the disc, and is subsequently deflected in an increasingly radial direction until it crosses the disc using the apertures and arranged from a centrally Suction is sucked off. Removed material can thus be removed efficiently and without burdening the ambient air.

The pressing unit 9 is arranged on a cross member carriage 5 and in particular comprises a AnpressZylinder 10, such as a pneumatic cylinder. The pressure cylinder 10 is on the one hand fixedly mounted on the cross member carriage 5, wherein the piston of the Anpresszylinders 10 moves a guided on the cross member carriage 5 actuator, which is firmly connected to the carrier 4. The contact pressure of the pressing unit 9 is preferably infinitely controllable, wherein the contact pressure together with the feed rate set the milling or grinding depth. Furthermore, an adjusting motor 11 is arranged on the cross member carriage 5, which causes the vertical up and down movement of the cross member carriage 5 on the cross member 2, such as by a gear is driven, which meshes with a arranged on the cross member 2 rack.

In Fig. 4, the pivot arm 7 can be seen, via a rotary drive in Rotation can be offset. The rotary drive is arranged either at the free end of the pivot arm 7 in order to shorten the transmission path for the torque from the rotary drive to the disc 8, or it is arranged on the carriage 6 and connected to the disc 8 via a transmission which bridges the pivot arm 7. The swivel drive 12 is "* *« * • • • • • • • • • • • • • 90 90 90 90 • · · · · «« «« «« «« «« « * 9t ··· «9 · 9 · 9 ·· 9 99 ··· 99 · preferably arranged on the carriage 6. For reasons of better clarity, hose or cable feeds are not shown in FIGS. 4 and 5. The disc 8 is provided on its, the wall surface 1 facing disc surface as with chip-removing abrasive elements 19 made of polycrystalline diamond (PCD).
    In order to compensate for unevenness and to preserve the disc 8, the disc 8 is resiliently mounted on the pivot arm 7, for example by means of a plate spring.
