Definitions
- the present invention relates to a device for editing and enlarging the clear cross section or the inner contour of an earthworks, e.g. a channel according to the preamble of claim 1.
- a processing device for enlarging the clear channel cross-section is for example, in AT 396 270 described.
- the removal tool is kept movable along a gate, wherein the Kulisse thereby the profile to be machined to produce according to the Adapt processing machine respectively.
- the known device has a carrier which is clamped in the clear cross section.
- the machining tool on the frame by a free-guided robotic arm to keep its movements controlled profile are.
- WO 90/12979 shows an apparatus for processing pipe systems in the shape of a pig, which is mounted on several training wheels.
- the newt carries on a cantilever arm a tool.
- the boom is in the radial direction pivotally mounted on a bogie, which is about a longitudinal axis is pivotable.
- the tool can be in any position be brought to the pipe wall.
- Such a device is for inspection or smaller Maintenance work, in particular in channel systems with a small cross section, quite suitable.
- rough work with a device of this structure are not readily executable.
- the cross-sectional widening by milling is problematic because of this Way no favorable angle for the milling tool can be reached.
- the relatively large occurring forces can not optimally from the movement mechanism be recorded.
- DE 20 27 192 shows a tunneling machine, which is designed to a Tunnel cross section from the full break out.
- a tunneling machine does not give the problem of the angle of attack or in completely different Shape. It is described in this document a storage of the milling head, the pivotal movement about a substantially vertical axis and a this axis provides intersecting horizontal axis. It turned out that such a kinematics not optimal for the extension of tunnel cross sections is.
- Object of the present invention is to avoid these disadvantages and to create a device of the type mentioned, which is optimal for the task the cross-sectional widening is adjusted, and in which a known Movable basic unit in a particularly simple manner to any contours is customizable and automatic control of the feed, for example along a route guiding device is made possible.
- the device Due to the kinematics of the boom are the necessary conditions created, the device jos vided on a beam or align a guide beam and each work out the desired nominal profile.
- the substantially horizontal Swivel axis on a slide or swingarm adjustable in height direction arranged, where it is sufficient for the exact control, each in the align the essential horizontal pivot axis on the route guide, in each case in the narrowed or to be enlarged clear cross section, the correct geometric conditions with respect to the target profile to be able to comply.
- the inventive training is made so that the pivot axis for the horizontal pivoting of the boom essentially normal to the horizontal pivot axis, whereby in particular deviating from the circular shape inner contours or clear cross sections be safely coated with the boom and the milling tools can.
- the required control signals arise in such a design as X and Y coordinates of the respective nominal profile in the machining cross section wherein the orientation of the substantially horizontal pivot axis sufficient to an automatic method along a guide beam analog to allow for the process along a route guide.
- the training is such that the actuators for vertical and horizontal pivoting of the extension arm are formed by hydraulic cylinders whose position from a control circuit is monitored and adjusted in dependence on a predetermined nominal profile becomes.
- the gimbal bearing and the device for adjustment the altitude of the horizontal pivot axis subsequently to any known movable devices are grown, due to the geometric Design an automatic process in a simple manner possible becomes.
- a secure adjustment and positioning of the device in the clear cross-section can be ensured in a simple manner that the carrier at least carries three support rollers on arms, which in the cross-sectional plane Y-shaped arranged and adjustable in the direction of the inner surface of the profile.
- the Use of a substantially Y-shaped arrangement of the support rollers allows in particular for cross sections which deviate from the circular shape, a large degree of self-centering of the device, so that the required Effort for Nachkorrekturen be kept low on Streckenleitstrahl can.
- a process control can be used to carry different profiles precisely control the hydraulic piston, the device without consuming Retooling can be used universally.
- the training is made such in that the milling tool is at the rear end in the direction of advancement or displacement the carrier is arranged on the boom.
- the milling tools of milling or Milling heads are formed, whose axis of rotation with the axis of the cantilever arm flees.
- a configuration can by appropriate head shape and head geometry each a largely flat contact of the cutting tools with the inner contour or the inner wall of the light to be enlarged Cross-section can be maintained, reducing the working speed can be increased.
- the axis of rotation the milling tool is transverse to the axis of the cantilever arm.
- the device is preferably designed such that the pivot axes of the boom to a beam, in particular a laser beam, are alignable.
- a beam in particular a laser beam
- the training is made so that at least one of Rollers connected to a traction drive.
- the present invention relates to a method for editing and enlarging the clear cross-section or the inner contour of a Erdbauwerkes, z. B. a channel, preferably using a device through the above described type.
- a milling tool used which is attached to a cantilever, the gimbal stored at a point that is at the height of a horizontal diameter an outer enveloping circle is arranged around the desired profile shape.
- a frame 1 can be seen on which wheels 2 and 3 rotatable are stored.
- the impeller 3 is connected to a drive motor, not shown, wherein the wheels are movable on the sole of a channel profile 4.
- the boom 7 is hinged gimbal, wherein the substantially vertical pivot axis is denoted by 8.
- the boom 7 carries on his front end coaxial with the axis of the boom rotatably mounted milling or cutting tools 9, wherein the corresponding drive motor with 10th is designated.
- the substantially vertical pivot axis 8 is in this case of a fork 11 of the extension arm 7 embraced, so that a secure recording the reaction forces is enabled.
- the pivot drive for the pivoting of the boom 7 to the in essential horizontal axis 6 is formed by a hydraulic cylinder 12, which engages an arm 13 of the universal joint.
- the pivoting in im substantially horizontal direction is caused by the hydraulic cylinder 14, wherein these two hydraulic cylinders 14, 12 via control lines 15 and 16 with a central control device 17 are connected, which also the signals a Leitleit issued not shown processed.
- the rocker 5 is pivoted by a hydraulic cylinder 18, so that the horizontal pivot axis 6 substantially diametrically in the enveloping circle of the Channel cross-section of the channel 4 runs.
- a centering or more Support is ensured by support rollers 19, which via hydraulic cylinders 20 against the inner wall of the channel 4 can be pressed and in one common carrier 21 are stored.
- the Carrier 21, which were indicated by dash-dotted lines, preferably Y-shaped be arranged, wherein at a substantially egg-shaped cross-section together with the lower driven support roller 3, a self-adjustment is possible.
- the support rollers 19 but can also deviate from the dot-dash line indicated location can be oriented in any way, as with the drawn in full lines rollers 19 is illustrated.
- the outside of the profile cross-section is surrounding Envelopes marked 22.
- the substantially horizontal pivot axis is in each case aligned with the horizontal diameter 23 of this enveloping circle, so that an exact adjustment of the entire device at one Routing beam can be done.
- the extension arm 7 on both sides separate hydraulic cylinder 14 are used, wherein the substantially horizontal pivot axis 6 in Height direction along the indicated with 24 vertical longitudinal center plane of is to be machined clear cross-section adjustable.
