[0030] Fig. 1 , 2 , and 3 to 10Figure 1 shows a system 1 according to the invention, in particular comprising an adjustment device 2, and a method according to the invention for automatically adjusting a variable mast position MS of an adjustable distribution mast 3 of a construction and / or high-viscosity pumping device 4. At least one same tip position SPO of a mast tip 3S of the distribution mast 3 can be achieved by different mast positions MS, MS'.

[0031] Furthermore, system 1, in particular the setting device 2, is designed to determine and set a mast position MS depending on a given size VG, determining a top position SPO and based on an optimization criterion OK, in particular determining and setting it.

[0032] Furthermore, the procedure includes the step: Determining and adjusting the mast position MS depending on the given size VG determining the top position SPO and based on the optimization criterion OK, in particular by means of system 1, in particular the adjustment device 2.

[0033] The optimization criterion OK is a minimized tipping moment KM of the distribution mast 3 with respect to a support system 7 of the construction and / or high-viscosity pumping device 4, in particular a mast base 3F of the distribution mast 3. The tipping moment KM depends on the mast position MS.

[0034] In the illustrated embodiment, the system 1 includes the distribution mast 3, in particular the construction and / or high-viscosity pumping device 4.

[0035] In detail, the distribution mast 3 has several adjustable mast joints 5a, 5b, 5c, 5d, 5e. The mast position MS can be changed by a variable joint position combination GSK of the mast joints 5a-e. The same tip position SPO can be achieved by different joint position combinations GSK, GSK'. In particular, the mast joints 5a, 5b, 5c, 5d, 5e have different adjustment ranges 5Va, 5Vb, 5Vc, 5Vd, 5Ve. This step involves: determining and setting a joint position combination GSK depending on the given value VG and based on the optimization criterion OK, in particular and taking into account the adjustment ranges 5Va-e, in particular by means of system 1, in particular the setting device 2. The tipping moment KM depends on the joint position combination GSK.

[0036] In detail, the distribution mast 3 can be rolled and / or Z-folded by means of the mast joints 5a-e, in particular rolled-Z-folded.

[0037] Furthermore, the distribution mast 3 has several mast segments 6a, 6b, 6c, 6d, 6e, which are adjustable, particularly relative to each other. The mast position MS can be changed by a variable adjustment combination VSK of the mast segments 6a-e, particularly relative to each other. The same tip position SPO can be achieved by different adjustment combinations VSK, VSK'. In particular, the mast segments 6a, 6b, 6c, 6d, 6e have different masses ma, mb, mc, md, me and / or different lengths La, Lb, Lc, Ld, Le and / or different center of gravity positions GPa, GPb, GPC, GPd, GPe. The step involves: Determining and setting an adjustment combination VSK depending on the given size VG and based on the optimization criterion OK, in particular and taking into account the masses ma-e and / or the lengths La-e and / or the center of gravity positions GPa-e, in particular by means of the system 1, in particular the adjustment device 2.The tilting moment KM depends on the adjustment combination VSK.

[0038] In the illustrated embodiment, the distribution mast 3 has five adjustable mast joints 5a-e. In alternative embodiments, the distribution mast can have at least three mast joints.

[0039] Furthermore, in the illustrated embodiment, the distribution mast 3 has five mast segments 6a-e. In alternative embodiments, the distribution mast can have at least three mast segments.

[0040] Background: A mast joint and / or a mast segment allows movement of the masthead. Two mast joints and / or two mast segments allow free movement of the masthead, in particular where height and radius are independent of each other, especially within certain limits. At least three mast joints and / or at least three mast segments allow free movement of the masthead and adjustment of the mast position over at least one degree of freedom. In other words: N mast joints and / or N mast segments with N ≥ three allow free movement of the masthead and adjustment of the mast position over N-two degrees of freedom.

[0041] Furthermore, in the illustrated embodiment, a radius or distance r and / or a direction or angle RI of the distributor mast 3, in particular its mast tip 3S, especially in relation to its mast base 3F and / or the support system 7, can be changed by the variable joint position combination GSK and / or the variable adjustment combination VSK.

[0042] Furthermore, the step involves: Determining and adjusting a change VMS starting from an actual mast position IMS based on a, in particular maximum, minimization starting from an actual tipping moment IKM of the distributor mast 3 with respect to the support system 7, in particular by means of the system 1, in particular the adjustment device 2. The actual tipping moment IKM depends on the actual mast position IMS.

[0043] Background: the tilting moment KM, in particular the actual tilting moment IKM, especially a function of the tilting moment KM depending on the mast position MS, is, for example: KM = g ⋅ ∑ i = 1 , a N , e l G , i ⋅ m i , N ≥ 3 g . . Erdbeschleunigung 9 , 81 m s 2 l G,i .. Lever arm for the weight force of mast segment i mi .. Mass of mast segment i

[0044] The lever arms of the mast segments 6a-e depend on the mast position MS, in particular the actual mast position IMS, e.g.: l G , i = r i + L , x SP , i ⋅ cos φ R , i r i = ∑ j = 1 i − 1 l j ⋅ cos φ R , j , r 1 , a = 0 l G , i = L , x SP , i ⋅ cos φ R , i + ∑ j = 1 i − 1 l j ⋅ cos φ R , j φ R , i = ∑ j = 1 i φ G , j φ.. Adjustment coordinate, in particular angle, of the mast joints 5a-e

[0045] In particular, minimizing the tipping moment KM, especially starting from the actual tipping moment IKM, means, for example, deriving the function of the tipping moment KM after the change VMS of the mast position MS, especially the adjustment coordinate or the angle of the mast joints 5a-e, especially starting from the actual mast position IMS: KM . = dKM dt = ∂ KM ∂ φ → G ⋅ ω → = C , with C < 0 , φ → G = φ G , 1 , a ⋮ φ G , N , e , ω → = ω 1 , a ⋮ ω N , e = d φ → G dt .

[0046] Determining, in particular setting, the velocities of the mast joints 5a-e, especially solely or purely, to minimize the tilting moment KM, is possible, for example, via pseudo-inverse or inverse direct kinematics: ω → red = ∂ KM ∂ φ → G + ⋅ C

[0047] Furthermore, the step involves: controlling, in particular regulating, the mast position MS to achieve and / or maintain the peak position SPO, in particular a target peak position SSPO, in particular starting from an actual peak position ISPO of the distribution mast 3 and / or during the determination and adjustment of the change VMS and / or as long as the actual tipping moment IKM is minimized, in particular by means of system 1, in particular the adjustment device 2.

[0048] Background: Reaching and / or holding, in particular holding, the mast tip 3S e.g. via a controller, in particular the adjustment device 2.

[0049] A deviation of the peak position SPO, in particular the actual peak position ISPO, from the target peak position or the target value SSPO leads to a position error, e.g.: e → SPO = r → SPO , soll − r → SPO , ist

[0050] To minimize the positional error, a movement of the mast tip 3S to the target tip position SSPO can or should be initiated, e.g. via a simple proportional control law: v → SPO = k p ⋅ e → SPO

[0051] A mapping to the velocities of the mast joints 5a-e is possible, for example, via the following relationship: v → SPO = ∂ r → SPO ∂ φ → G ⋅ ω →

[0052] Furthermore, the step involves: determining and adjusting the change VMS and controlling, in particular regulating, the mast position MS by determining a solution LS for a kinematic relationship KIZ of minimizing the actual tipping moment IKM and achieving and / or maintaining the tip position SPO together, in particular by means of system 1, in particular the adjustment device 2.

[0053] Background: the last-mentioned function or requirement can be addressed by minimizing the tipping moment KM, in particular this function or requirement, e.g. by the vector equation C v → SPO = ∂ KM ∂ φ → G ∂ r → SPO ∂ φ → G ⋅ ω → can be combined, in particular to form a combined Jacobian matrix, specifically composed of, in particular, the function of the change in the tilting moment and, in particular, the function of a movement of the mast tip, or to form the kinematic relationship KIZ. For three mast segments, this kinematic relationship KIZ or this equation is exactly solvable. In general, it can be useful to directly impose at least one additional requirement on the velocities of the mast joints 5a-e. This can either serve to proceed as efficiently as possible, such as: ω → 2 = min or to take into account at least one, and in particular all, of the adjustment ranges 5Va-e. To integrate the efficiency of the procedure into the analysis, the following requirement, for example, can be used: ω → gef = 0 →

[0054] To take into account at least one, and in particular all, of the adjustment ranges 5Va-e, a travel or movement command can be requested, for example, depending on the joint position GS of one of the mast joints 5a-e, within the adjustment range 5Va-e, and in particular the associated one. If, for example, the angle of the first mast joint 5a, in particular at the mast base 3F, is close to a limit value, then, for example: ω 1 , gef = D , in particular with D < 0 near an upper limit and / or D > 0 near a lower limit. The relationship of the vector of the required velocities of the mast joints 5a-e can be represented, for example, using the identity matrix: ω → gef = ω 1 , gef ⋮ ω N , gef = 1 0 ⋱ 0 ⋱ 0 ⋱ 0 1 ⋅ ω → = E N ⋅ ω →

[0055] With this additional requirement or condition or function, the kinematic relationship KIZ, in particular the overall relationship, or the combined Jacobian matrix, results: C v → SPO ω → gef ≈ ∂ KM ∂ φ → G ∂ r → SPO ∂ φ → G E N ⋅ ω →

[0056] This kinematic relationship KIZ represents an overdetermined system of equations that generally cannot be solved exactly. Instead, the best solution LS of this system of equations can be determined, for example, in terms of least squares. This can be achieved by minimizing the sum of the squares of the errors in the equation above. The cost functional of this optimization is: K ω → = C v → SPO ω → gef − ∂ KM ∂ φ → G ∂ r → SPO ∂ φ → G E N ⋅ ω → T ⋅ W ⋅ C v → SPO ω → gef − ∂ KM ∂ φ → G ∂ r → SPO ∂ φ → G E N ⋅ ω →

[0057] In order to prioritize the individual components of the procedure or process (minimizing the tipping moment KM, achieving and / or maintaining the target tip position SSPO, and implementing the required speeds of the mast joints 5a-e), especially if they differ, these components can be considered with different weightings in the cost functional K. The diagonal matrix W can display, and in particular contain, these weights.

[0058] Since this is a linear relationship, it can be solved directly using a general least-squares solution, for example: ω → opt = ∂ KM ∂ φ → G ∂ r → SPO ∂ φ → G E N T ⋅ W ⋅ ∂ KM ∂ φ → G ∂ r → SPO ∂ φ → G E N − 1 ⋅ ∂ KM ∂ φ → G ∂ r → SPO ∂ φ → G E N T ⋅ W ⋅ C v → SPO ω → gef

[0059] Alternatively, and particularly advantageous in this or the present case, the cost functional can also be minimized iteratively using its gradient: ∂ K ω → ∂ ω → = − 2 ∂ KM ∂ φ → G ∂ r → SPO ∂ φ → G E N T ⋅ W ⋅ C v → SPO ω → gef − ∂ KM ∂ φ → G ∂ r → SPO ∂ φ → G E N ⋅ ω → take place: ω → opt , i + 1 = ω → opt , i + λ ⋅ ∂ K ω → ∂ ω → ω → = ω → opt , i , with the step size parameter λ and a starting value ω opt, 0, which in the simplest case can simply be chosen to be equal to the zero vector.

[0060] Furthermore, the support system 7 is adjustable. The method comprises the step: locking mast positions MS" and / or tilting moments KM" depending on a determined quantity EG, determining at least one variable support configuration ASK of the adjustable support system 7 to counteract the tilting moment KM, in particular by means of the system 1, in particular the adjustment device 2.

[0061] Furthermore, the distribution mast 3 has a conveying line 8 for conveying construction and / or thick material BDS, in particular conveying.

[0062] Furthermore, distribution mast 3 has an end hose, in particular a freely hanging one.

[0063] In particular, the end hose can be taken into account in the mass me and / or the center of gravity position GPe of the, in particular the last, mast segment 6e.

[0064] As the exemplary embodiments shown and explained above clearly demonstrate, the invention provides an advantageous method for automatically adjusting a variable mast position of an adjustable distribution mast of a construction and / or thick substance pumping device and an advantageous system, in particular one which has improved properties.

[0065] In other words, the method and / or system for automatically minimizing the tipping moment enables the operator / user to maximize the utilization of the working space by releasing it based on the actual tipping moment. Upon reaching the limit of the released working space, the distributor boom can be repositioned with the simple push of a button to minimize the actual tipping moment, thereby releasing further portions of the working space. This allows the operator / user, without needing to understand the relationship between tipping moment and boom position, to operate the construction and / or high-viscosity pumping equipment within the maximum possible range and with minimal outrigger width.
