Abstract
Abstract The invention relates to an arrangement for cleaning the surfaces of aircraft with a large manipulator having a rotating brush head consisting of several extensions (12, 12', 12", 14) pivotable on articulations (20, 22, 24, 28) by means of hydraulic drive systems (30) and fitted on a rotary bracket (11) of a motor-driven chassis (10) with its base extension (12) fitted on an angled mast to rotate about a main axis (11) and a multiple articulation (16) on the end extension (14) at the free end. To provide starting auxiliary for the chassis (10), the adaptation of the large manipulator to the aircraft and/or monitoring facilities for the cleaning process, there is an opto-electronic distance camera (40) and a computer-supported electronic evaluation system to which the output signals of the distance camera (40) are applied.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
240 words
An arrangement for the surface treatment of large objects, comprising a large manipulator having an articulated mast, the articulated mast consisting of several arms which are pivotally connected to one another on pivot joints, driving means for pivoting adjacent ones of said several arms at said pivot joints, one of said several arms being a base arm rotatably supported about a vertical axis on a pivot-bearing block of an apparatus carrier, and said mast having a tool arranged on one of a last arm of the several arms and a multiple joint having a free end arranged on the last arm, the articulated mast having a collapsed state supported on the apparatus carrier having the base arm being supported under the other arms on the apparatus carrier, and the last arm being arranged with the multiple joint extending in a direction toward the pivot-bearing block and the tool being adjacent the other arms, wherein the improvement comprises an opto-electronic distance camera being aligned with respect to the large object to be treated, being arranged on a console mounted on a side of the articulated mast in the collapsed state supported on the apparatus carrier, and being rotatable about the vertical axis together with the articulated mast, and calculator-supported evaluating electronics receiving output signals from the distance camera for performing at least one of locating the large manipulator relative to the large object to be treated and monitoring the treatment operation.
Claim 2
Dependent Claim
240 words
An arrangement for the surface treatment of large objects, comprising a large manipulator having an articulated mast, the articulated mast consisting of several arms which are pivotally connected to one another on pivot joints, driving means for pivoting adjacent ones of said several arms at said pivot joints, one of said several arms being a base arm rotatably supported about a vertical axis on a pivot-bearing block of an apparatus carrier, and said mast having a tool arranged on one of a last arm of the several arms and a multiple joint having a free end arranged on the last arm, the articulated mast having a collapsed state supported on the apparatus carrier having the base arm being supported under the other arms on the apparatus carrier, and the last arm being arranged with the multiple joint extending in a direction toward the pivot-bearing block and the tool being adjacent the other arms, wherein the improvement comprises an opto-electronic distance camera being aligned with respect to the large object to be treated, being arranged on a console mounted on a side of the articulated mast in the collapsed state supported on the apparatus carrier, and being rotatable about the vertical axis together with the articulated mast, and calculator-supported evaluating electronics receiving output signals from the distance camera for performing at least one of locating the large manipulator relative to the large object to be treated and monitoring the treatment operation.
Claim 3
Dependent Claim
14 words
The arrangement according to claim 1, wherein said tool is a rotating brush head.
Claim 4
Dependent Claim
53 words
The arrangement according to claim 1, wherein the distance camera is arranged on the large manipulator near the pivot-bearing block by a positioning means for selectively rigidly securing the distance camera to the console, for pivoting the distance camera about a vertical axis, and for inclining the distance camera about a horizontal axis.
Claim 5
Dependent Claim
28 words
The arrangement according to claim 1, wherein the base arm is supported pivotally having a pivot angle of approximately 180° about a horizontal axis on the pivot-bearing block.
Claim 6
Dependent Claim
39 words
The arrangement according to claim 1, wherein the base arm has a concave curvature opening upwardly remote from the apparatus carrier for receiving a second arm of the several arms hinged to the base arm in the collapsed state.
Claim 7
Dependent Claim
42 words
The arrangement according to claim 5, wherein the pivot joints provided at both ends of the second arm lie lower than a base pivot joint connecting the base arm to the pivot-bearing block when the articulated mast is in the collapsed state.
Claim 8
Dependent Claim
29 words
The arrangement according to claim 1, wherein the base arm and a second arm of the several arms attached at one end of the base arm both extend bend-free.
Claim 9
Dependent Claim
50 words
The arrangement according to claim 7, wherein the last arm is laterally bent with respect to a third arm of the several arms, and wherein the tool is supported near the pivot joint of the base arm on the pivot-bearing block when the articulated mast is in the collapsed state.
Claim 10
Dependent Claim
22 words
The arrangement according to claim 8, wherein said second and third arms are pivotally connected at one pivot joint to each other.
Claim 11
Dependent Claim
26 words
The arrangement according to claim 8, wherein the third arm is laterally bent with respect to the second arm toward the side opposite the last arm.
Claim 12
Dependent Claim
153 words
The arrangement according to claim 1, wherein the multiple joint has three pivot points driven by a motor, said three pivot points defining three axes arranged orthogonal to each other, and has a telescopible linear part connected to a last pivot point of the three pivot points, the telescopible linear part being aligned with the pivot axis of the last pivot point, being drivable by a motor, and being aligned in the collapsed state of the articulated mast parallel with respect to the last arm, wherein the tool is coupled through a further pivot point having an orientation axis perpendicular with respect to the telescopic axis of the telescopible linear part to the multiple joint, and the axes of the pivot point on the side of the last arm and of the linear part are arranged in planes, which are laterally offset with respect to one another and are parallel to one another.
Claim 13
Dependent Claim
