Description

Field of application of the invention

The invention relates to a device for suspending and guiding rotating tools for processing vertical and vertical inclined surfaces, such as building facades to be reconstructed, building interior walls and corrosion-damaged surfaces of hydraulic structures.

Characteristic of the known state of the art DE 3039698 describes a device in which a tool, preferably a rotary tool, vibrates

offset and guided under pressure over a rigid Führungsami along the layer to be processed.

The rotating tool is rigidly connected to the boom of the guiding device. That means that bumps of the too

machined surface and the surface to be traveled by the guide device during the processing layer must be constantly compensated to ensure the required pressure of the tool against the layer to be processed. From the practice of mechanized processing of facades is well known that such

Guide the tool along the facade with manual control is not possible. The reason is that of Operators simultaneously several directions of movement must be corrected and multiple controls simultaneously

must be controlled exactly.

In DE 2648960 idt a device for milling of wall surfaces idt described in which a face milling cutter and horizontal

vertically parallel to the wall surface. As guide arms serve Rüststangen that are braced against the ceiling and floor. Due to the positive guidance of the milling cutter is also a constant position correction relative to the wall to be machined required to compensate for bumps.

This is counteracted that the alignment of the frame with respect to the wall surface to be processed is very expensive. There a Counterweight only serves to facilitate the vertical movement of the cutter during machining and due to the Forced operation does not work in the direction of the wall, the cutter is manuoll via a fine adjustment in the layer to be processed

pushed in, then to be moved vertically with the assistance of acting as counterbalance counterweight.

This process is repeated at each beginning of a new work path. The experiences made so far with the milling of wall surfaces show for positive-guided tools negative results, as with

the positive guidance equally coercive forces arise that lead to excessive wear of the tools and must be intercepted by the carrier device. So far, devices have not enforced according to DE 3039698 and DE 2648960 in the construction practice for the reasons mentioned.

7Ie of the invention

The aim of the invention is to significantly increase the labor productivity in the processing of vertical and vertical inclined surfaces, especially of buildings, to minimize the equipment and the operating effort of the device and obstacles in front of the surface to be machined, such. As plantings, crops, etc., to be able to leave.

Explanation of the essence of the invention

The invention has for its object to develop a device for suspending and guiding rotating tools, the required pressure of the rotating tool to the surface to be machined and the position of the rotating tool to the surface to be machined largely independent of the current position of the boom of the carrier self-regulated, so that must be provided to the carrier in terms of guiding accuracy and its location no particular claim. "

According to the invention, a rotating tool is attached to a strong boom of a mobile carrier device (eg excavator, loader, forklift, manipulator or similar construction machine) so that it can freely move around all three axes of rotation of the suspension point and that between suspension point and rotating tool a rigid intermediate member is arranged. This ensures that, regardless of the position of the jib of the carrier device to the surface to be machined, the axis of rotation of the rotating tool can be performed parallel to the surface to be machined with horizontal axis of rotation. The device is structurally designed, and so attached to the suspension point that during the

strip-shaped processing of the surface to be machined, the center of gravity of the device is always on the side opposite the facade of the suspension point. This ensures that during a strip-shaped removal in the vertical direction, preferably from bottom to top, an independent Ausgleich of unevenness of the surface to be machined and motion deviations from the vertical by the boom of the carrier without constant position correction

Device for the surface to be machined by the operator is possible. At the side of the suspension point opposite the surface to be machined, a device is attached to the device Mounted additional masses for shifting the center of gravity in this direction. This ensures that, depending on the type of layer to be removed and the size of the rotating tool

the required pressure of the rotating tool against the surface to be machined can be adjusted.

embodiment

The invention will be explained in more detail with reference to an embodiment. In the drawings show:

Fig. 1: The suspension device with rotating tool on the boom of a wheeled excavator in working position Flg. 2: The device system in plan view Fig. 3: The suspension in the rear view Fig.4: Suspension device before approaching the surface to be machined Fig. 5: The suspension in the side view with the rotating tool in operation. A rotating tool 1 is mounted in a frame 2. At the opposite side of the rotating tool 1 Frame 2, the Zyi 3 is attached. At the upper end there is the clutch 4, which is the turning of the Frame 2 ensures about the axis 5. Frame 2, intermediate member 3, member-side clutch disc 6 and Additional masses 7 form the suspension device. Above the Zwischengiiedseitigen clutch disc β is the

Excavator-side clutch disc 8. The horizontal axis of rotation 9 ensures the oscillation of the suspension in

Direction of the surface 12 to be machined and the coupling axis of rotation 10, the pendulum movement of the suspension

parallel to the surface to be worked. This is gr.wäh ', eistet that regardless of the spatial position of the rigid arm of the mobile carrier device 11 to the surface 12 to be machined the axis of rotation 13 of the rotating tool 1 is always horizontal and rests over its entire working width 14 on the surface to be machined 12 ,

The removal of the layer is preferably carried out from bottom to top in the mating principle. Due to the arrangement of the Center of gravity of the entire device on the surface 12 to be machined opposite side of the horizontal Rotary axis 9, the frame 2 is directed to the rotating tool 1 when coupling the hitch to the Carrier, as shown in FIG. 4 can be seen against a perpendicular line at an acute angle α. When editing in the surface, i. H. when tool engagement, changed by the restoring force from the working resistor

the skew of the frame 2 with respect to a perpendicular up to an obtuse angle α '.

This adjustment behavior of the suspension device causes unevenness and inclinations of the surface to be processed

and guide deviations compensated by the Ausloger of the mobile carrier device 11 automatically.

Up and down is the working space 15 of the rotating tool 1 with rubber sleeves 16 zumAßichtunggegendie

provided to be working surface.

The removed material escapes the working space 15 of the rotating tool 1 through the downpipe 17. When using different sized rotating tools 1 is the optimal mass balance by the change

the number of parts of the additional mass 7 guaranteed.

The particular advantages of this suspension device are the simple and robust design, in the Possible application of different carrier devices and in the adaptability of different width tools and before

especially in the automatic guidance of the active substance in inclinations and unevenness of the surfaces to be worked.

Another advantage of this design is that it can bypass the extensions on the facade η and Plantations need not be eliminated.
