Description

[0001] The invention relates to a method for operating a construction and / or thick matter pump for conveying construction and / or thick matter and a construction and / or thick matter pump for conveying construction and / or thick matter.

[0002] DE 10 2013 104494 A1 discloses a thick matter pump with at least one delivery cylinder, with a delivery piston guided in the at least one delivery cylinder, which is intended to be moved from a first dead center to a second dead center in a delivery cycle, and with an adjustment unit and a control and / or regulating unit, which are intended to change at least one feed speed and / or a feed pressure of the at least one delivery piston during the delivery cycle, wherein the control and / or regulating unit is intended to divide the delivery cycle into at least two different sub-sections, for which the feed speed and / or the feed pressure can be individually adjusted.DE 10 2013 104494 A1 does not describe the determination of the profile of a subsequent movement of the delivery piston by linking a detected position variable of the delivery piston and a detected delivery variable indicative of the position of a line switch with one another in such a way that the subsequent movement of the delivery piston and an adjustment of the line switch are synchronized.

[0003] US 6,779,983 B1 discloses a pump for viscous material (slurry), a method for accurately estimating the output of such a pump, and a method for efficiently managing such a pump. The pump can be a single- or double-cylinder pump. The pump is calibrated to determine a calibrated slurry weight output of the pump using a parameter defined as the "lost-path" position of the piston in the pump chamber. This position is defined by the position of the piston in the chamber when the pressure in the chamber reaches a preselected reference pressure, which is expressed as a percentage of the maximum pressure reached in the chamber during a just-previous discharge stroke of the piston. The lost-path parameter is used for comparison purposes to accurately estimate the actual pump output based on the calibrated pump output at the calibrated value of the lost-path parameter.The pump is efficiently controlled by controlling the speed of the auger. This ensures that a near-optimal amount of material is loaded into the pumping chamber during each pumping cycle. The pump is also controlled by managing the pump stroke and speed. TASK AND SOLUTION

[0045] In the illustrated embodiment, the construction and / or slurry pump 1 has at least one drive cylinder 10a, 10b, at least one drive piston 11a, 11b, and at least one piston rod 12a, 12b. The drive cylinder 10a, 10b is designed to receive hydraulic fluid HF, in particular, receives it. The drive piston 11a, 11b is movably arranged in the drive cylinder 10a, 10b. The piston rod 12a, 12b is attached to the drive piston 11a, 11b for movement coupling with the delivery piston 3a, 3b.

[0046] Furthermore, in the illustrated embodiment, the position variable PGa, PGb is a position of the drive piston 11a, 11b. In alternative embodiments, the position variable can be a position, in particular the position of the delivery piston or the piston rod.

[0047] In addition, in the embodiment shown, the construction and / or thick matter pump 1 has at least one drive motor device 13 and at least one drive pump device 14 for moving the delivery piston 3a, 3b, in particular moving it.

[0048] In detail, the drive motor device 13 is designed to drive or move the drive pump device 14, in particular drives or moves it. Furthermore, the drive pump device 14 is designed to pump or move hydraulic fluid HF at a pressure, in particular a drive pressure, p, and thus to move the drive piston 11a, 11b, in particular in the drive cylinder 10a, 10b, and thus to move the piston rod 12a, 12b and thus to move the delivery piston 3a, 3b.

[0049] In addition, the control device 7 is designed to control the drive motor device 13 and the drive pump device 14 to control the subsequent movement according to the determined profile, in particular controls, as in Fig. 3 shown.

[0050] In the exemplary embodiment shown, the construction and / or slurry pump 1 has, in particular, two delivery cylinders 2a, 2b, in particular, two delivery pistons 3a, 3b and, in particular, two displacement sensor devices 4a, 4b, in particular, two drive cylinders 10a, 10b, in particular, two drive pistons 11a, 11b and, in particular, two piston rods 12a, 12b. In alternative exemplary embodiments, the construction and / or slurry pump can have only a single delivery cylinder, only a single delivery piston and only a single displacement sensor device, in particular, only a single drive cylinder, only a single drive piston and only a single piston rod, or at least three delivery cylinders, at least three delivery pistons and at least three displacement sensor devices, in particular, at least three drive cylinders, at least three drive pistons and at least three piston rods.

[0051] Furthermore, in the illustrated embodiment, the construction and / or slurry pump 1 has a rocking line 15 for hydraulic fluid HF. The drive pump device 14 and the drive cylinders 10a, 10b form a drive circuit for hydraulic fluid HF by means of the rocking line 15. In other words: the drive cylinders 10a, 10b are connected by means of the rocking line 15 for a flow of hydraulic fluid HF, in particular between the drive cylinders 10a, 10b. The drive pistons 11a, 11b and thus the piston rods 12a, 12b and thus the delivery pistons 3a, 3b are coupled to one another by means of the rocking line 15, at least temporarily, in particular permanently, in particular in phase opposition, in particular 180 degrees in phase opposition, or for counter-rotating movement.

[0052] In Fig. 1 the drive piston 11a moves and thus the piston rod 12a moves and thus the delivery piston 3a moves to the right, as shown by an arrow. Hydraulic fluid HF flows from the drive cylinder 10a through the rocker line 15 to the drive cylinder 10b, as shown by an arrow. Thus, the drive piston 11b moves and thus the piston rod 12b moves and thus the delivery piston 3b moves to the left, as shown by an arrow. When the delivery pistons 3a, 3b, in particular, and the drive pistons 11a, 11b, have reached their, in particular respective, stroke end positions POAE, POVE, the directions of movement are swapped. Thus, the drive piston 11a moves and thus the piston rod 12a moves and thus the delivery piston 3a moves to the left and the drive piston 11b moves and thus the piston rod 12b moves and thus the delivery piston 3b moves to the right.

[0053] In particular, the construction and / or slurry pump can have a supply and / or discharge system for supplying and / or discharging hydraulic fluid into the rocking line. This can allow the drive pistons, and thus the piston rods and thus the delivery pistons, to be temporarily uncoupled or decoupled from each other, particularly for independent movement.

[0054] In addition, the construction and / or thick matter pump 1 has an adjustable line switch 9.

[0055] In the illustrated embodiment, the construction and / or thick matter pump 1 comprises a delivery line 8' and a construction and / or thick matter supply 20. The line switch 9 is designed to connect, in particular, either the delivery line 8' in one position or the construction and / or thick matter supply 20 in another position for a flow of construction and / or thick matter DS, the delivery cylinder 2a, 2b.

[0056] In Fig. 1 the line switch 9 connects the conveyor cylinder 2a with the conveyor line 8' and the conveyor cylinder 2b with the construction and / or thick material feed 20.

[0057] Furthermore, the delivery piston 3b sucks building and / or thick material DS, in particular from the, in particular connected, building and / or thick material supply 20, into the delivery cylinder 2b. At the same time, in particular, the delivery piston 3a displaces the sucked building and / or thick material DS out of the delivery cylinder 2a, in particular into the, in particular connected, delivery line 8'.

[0058] When the delivery pistons 3a, 3b have reached their, in particular respective, stroke end positions POAE, POVE, the line switch 9 is adjusted, in particular by means of the control device 7. The line switch 9 thus connects the delivery cylinder 2b to the delivery line 8' and the delivery cylinder 2a to the building and / or thick material feed 20. The delivery piston 3a thus sucks building and / or thick material DS, in particular from the, in particular connected, building and / or thick material feed 20, into the delivery cylinder 2a. In particular at the same time, the delivery piston 3b displaces sucked-in building and / or thick material DS out of the delivery cylinder 2b, in particular into the, in particular connected, delivery line 8'.

[0059] In addition, in the embodiment shown, the construction and / or thick matter pump 1 is designed as a mobile construction and / or thick matter pump, in particular as a car construction and / or thick matter pump, as in Fig. 2 shown.

[0060] Furthermore, the delivery variable FG' is characteristic of an input of energy from the delivery piston 3a, 3b into the building and / or thick material DS.

[0061] In detail, the feed quantity FG' is characteristic of the pressure, in particular the drive pressure, p acting on the building and / or thick material DS in the feed cylinder 2a, 2b, as shown in Fig. 4 shown.

[0062] In the embodiment shown, the conveying sensor device 5' has a pressure sensor device.

[0063] In addition, the delivery quantity FG' is characteristic of an excitation AN of at least one part 8 of the construction and / or thick matter pump 1 caused by the introduction of energy from the delivery piston 3a, 3b into the construction and / or thick matter DS, as in Fig. 2 shown.

[0064] In the embodiment shown, the conveyor sensor device 5' has an excitation sensor device, in particular an acceleration sensor device and / or a rotation rate sensor device.

[0065] Furthermore, in the embodiment shown, the, in particular one, part 8 is the conveyor line 8', in particular on the car, and the, in particular other, part 8 is a conveyor mast 8", in particular with the excitation sensor device of the conveyor sensor device 5' at a tip of the conveyor mast 8".

[0066] The method further comprises: determining a displacement start position POVA, at which the delivery piston 3a, 3b begins to displace sucked building and / or thick material DS from the delivery cylinder 2a, 2b, by linking the detected position variable PGa, PGb during the movement for displacement and the detected delivery variable FG' characterizing the input of energy from the delivery piston 3a, 3b into the building and / or thick material DS during the movement for displacement with each other, as in Fig. 4 shown, in particular by means of the determination device 6. Determining the profile PR based on the determined displacement start position POVA.

[0067] In the illustrated embodiment, the displacement starting position POVA is determined by linking the detected position variables PGa, PGb during displacement and the detected conveying variable FG' during displacement. In alternative embodiments, the displacement starting position can be determined by linking the detected position variables during movement to the determining displacement starting position and the detected conveying variable during movement to the determining displacement starting position.

[0068] In addition, in the embodiment shown, the displacement start position POVA is determined as the position POa, POb of the delivery piston 3a, 3b at which the delivery variable FG', in particular the pressure p, reaches or exceeds a limit value FG'limit, in particular plimit.

[0069] In Fig. 4 the delivery piston 3a moves, in particular from a suction or stroke end position POAE, to the right, as shown by an arrow. Initially, the delivery piston 3a moves due to vacuum or displaces building and / or thick material DS that has not yet been sucked in. The pressure p is therefore low. As soon as the delivery piston 3a reaches a nose of the building and / or thick material DS, the delivery piston 3a begins to displace or compress the building and / or thick material DS into a cylindrical shape, but not yet to displace it out of the delivery cylinder 2a. The pressure p therefore increases. As soon as the delivery piston 3a has displaced or compressed the building and / or thick material DS into the cylindrical shape, the delivery piston 3a begins to displace the building and / or thick material DS out of the delivery cylinder 2a, in particular into the delivery line 8'. The pressure p therefore reaches or exceeds the limit value plimit. The displacement start position POVA is thus determined.

[0070] In detail, the method comprises: determining a filling level FD of the conveyor cylinder 2a, 2b with building and / or thick material DS based on the determined displacement starting position POVA, in particular by means of the determining device 6, as in Fig. 3 Determining the profile PR of a subsequent movement for suction, in particular a subsequent suction, based on the determined filling level FD, as in Fig. 6 shown. Controlling the subsequent movement to the suction, in particular the subsequent suction, according to the determined profile PR.

[0071] Furthermore, the method comprises: determining a time period ZD for a previous movement for suction, in particular a previous suction, causing the determined displacement start position POVA and / or the determined filling level FD, as in Fig. 5 shown, in particular by means of the determining device 6. Determining a delivery quantity FM by linking the determined displacement starting position POVA and / or the determined filling level FD and the determined time period ZD with each other, in particular by means of the determining device 6, as in Fig. 3 Determining the profile PR of the subsequent movement to the suction, in particular the subsequent suction, based on the determined flow rate FM, as in Fig. 6 shown.

[0072] In addition, the method comprises: decreasing a speed v and / or increasing a standstill time SZD of the profile PR from a previous suction, as in Fig. 5 shown, to a subsequent suction, as in Fig. 6 shown, in particular by means of the determining device 6, until the displacement start position POVA no longer approaches the suction or stroke end position POAE and / or the filling level FD and / or the delivery rate FM no longer increase. Additionally or alternatively, increasing a speed v and / or decreasing a standstill period SZD of the profile PR from a previous suction, as in Fig. 5 shown, to a subsequent suction, as in Fig. 6 shown, in particular by means of the determining device 6, until the displacement start position POVA moves away from the suction or stroke end position POAE and / or the filling level FD and / or the delivery quantity FM decreases / decreases.

[0073] In Fig. 5 a standard profile SPR, in particular a standard acceleration and deceleration ramp, of the, in particular preceding, movement of the delivery piston 3a, 3b for the suction, in particular the preceding suction, of building and / or thick material DS with a standard viscosity is shown. However, if the building and / or thick material DS does not have the standard viscosity, but rather a different viscosity, then the standard profile SPR is not optimal. In particular, the, in particular determined, displacement start position POVA is not maximally close to the suction or stroke end position POAE, the, in particular determined, filling level FD is not maximum, and / or the, in particular determined, delivery rate FM is not maximum.

[0074] In Fig. 6 the profile PR of the, in particular subsequent, movement of the delivery piston 3a, 3b for the suction, in particular the subsequent suction, of building and / or thick material DS is shown, in particular by adaptation, in particular and iteration. The profile PR has or has, in particular in contrast to the standard profile SPR, a high speed v at a suction or stroke start position or displacement or stroke end position POVE. This enables a high initial suction vacuum to be generated quickly. Furthermore, the profile PR has or has, in particular in contrast to the standard profile SPR, a high speed v in a middle between the displacement or stroke end position POVE and the suction or stroke end position POAE or the stroke HU. This enables the, in particular determined, short time duration ZD. In addition, it has or hasThe PR profile, particularly in contrast to the standard SPR profile, has a low speed v and a long standstill time SZD at the suction or stroke end position POAE. This enables a high overrun effect. This thus enables a minimal vacuum. This thus enables the particularly determined displacement start position POVA to be as close as possible to the suction or stroke end position POAE, the particularly determined maximum filling level FD and / or the particularly determined maximum delivery rate FM.

[0075] Furthermore, the method comprises: determining the profile PR of a subsequent movement, in particular from the suction or stroke end position POAE, to a, in particular new or the, displacement start position POVA based on the determined displacement start position POVA, as in Fig. 4 shown. Controlling the subsequent movement to the displacement start position POAE according to the determined profile PR.

[0076] In detail, the method comprises: determining the profile PR such that the delivery piston 3a, 3b accelerates, in particular from the suction or stroke end position POAE, and subsequently brakes before the displacement start position POVA.

[0077] In other words: The profile PR has or shows an increase in the speed v at the intake or stroke end position POAE and subsequently a decrease in the speed v before the displacement start position POVA.

[0078] This makes it possible to reach the initial displacement position POVA in a minimum amount of time without the delivery piston 3a, 3b moving too quickly against the building and / or thick material DS.

[0079] In addition, the method comprises: determining a time duration ZD for the preceding movement for suction and / or for the determined subsequent movement for suction and / or for the preceding movement to the displacement start position POVA and / or for the determined subsequent movement to the displacement start position POVA, in particular by means of the determining device 6, as in Fig. 3 Determining a remaining time period RZD for a subsequent movement for displacement, in particular a subsequent displacement and / or up to the displacement or stroke end position POVE, by linking the determined time period ZD and a predetermined cycle and / or stroke time period HZD and / or a predetermined delivery quantity FM with each other, in particular by means of the determination device 6, as in Fig. 3 Determining the profile PR of the subsequent movement for displacement, in particular the subsequent displacement, in particular to the displacement or stroke end position POVE, based on the determined remaining time period RZD. Controlling the subsequent movement for displacement, in particular the subsequent displacement, according to the determined profile PR.

[0080] The method further comprises: determining the profile PR of the subsequent movement for displacement, in particular the subsequent displacement, in particular for the displacement orStroke end position POVE, by linking the detected position variable PGa, PGb during the movement for displacement, in particular the displacement, and the detected delivery variable FG' characteristic of the introduction of energy from the delivery piston 3a, 3b into the building and / or thick material DS, in the illustrated embodiment characteristic of an excitation AN of at least one part 8 of the building and / or thick material pump 1 caused by the introduction of energy from the delivery piston 3a, 3b into the building and / or thick material DS, during the movement for displacement, in particular the displacement, with one another in such a way that an excitation AN of at least one part 8 of the building and / or thick material pump 1 caused by the introduction of energy from the delivery piston 3a, 3b into the building and / or thick material DS is reduced or avoided. Controlling the subsequent movement for displacement, in particular the subsequent displacement, according to the determined profile PR.

[0081] In Fig. 4 the profile PR of the, in particular subsequent, movement of the delivery piston 3a, 3b for displacing, in particular the subsequent displacement, of building and / or thick material DS is shown, determined in particular by adaptation, in particular and iteration. The profile PR has or shows an increase in the speed v after the displacement start position POVA and subsequently a reduction in the speed v before the displacement or stroke end position POVE. In other words: the method comprises: determining the profile PR such that the delivery piston 3a, 3b brakes from the displacement start position POVA and subsequently before the displacement or stroke end position POVE. This makes it possible to reduce or avoid the remaining time period ZD and thus the cycle and / or stroke time period HZD and / or the delivery quantity FM and / or an excitation AN of at least one part 8.

[0082] In addition, the feed size FG" is characteristic for a position ST of the line switch 9, as in Fig. 2 , 4 and 6 shown.

[0083] In the embodiment shown, the conveyor sensor device 5" has a position sensor device.

[0084] Furthermore, in the embodiment shown, the construction and / or thick matter pump 1 has an adjustment system 19 for adjusting the line switch 9.

[0085] Furthermore, in the embodiment shown, the feed quantity FG" is a position of the actuating system 19. In alternative embodiments, the feed quantity can be the position of the line switch.

[0086] Furthermore, the control device 7 is designed to control the actuating system 19, in particular, as shown in Fig. 3 shown.

[0087] In detail, the method comprises: determining the profile PR of the subsequent movement for displacement to the displacement or stroke end position POVE and / or for suction from the displacement or stroke end position POVE and / or for suction to the suction or stroke end position POAE and / or for displacement from the suction or stroke end position POAE by linking the detected position variable PGa, PGb and the detected delivery variable FG" characteristic of the position ST of the line switch 9 with each other in such a way that the subsequent movement of the delivery piston 3a, 3b and the, in particular subsequent, adjustment of the line switch 9 are or are synchronized, as in Fig. 4 and 6 shown. Controlling the subsequent movement to the displacement or stroke end position POVE and / or from the displacement or stroke end position POVE and / or to the suction or stroke end position POAE and / or from the suction or stroke end position POAE according to the determined profile PR.

[0088] In Fig. 4 and 6 the profile PR of the, in particular subsequent, movement of the delivery piston 3a, 3b to the displacement or stroke end position POVE and / or from the displacement or stroke end position POVE and / or to the suction or stroke end position POAE and / or from the suction or stroke end position POAE is shown, determined in particular by adaptation, in particular and iteration. The profile PR is determined such that the delivery piston 3a, 3b is in the displacement or stroke end position POVE and / or the suction or stroke end position or is stationary precisely when the adjustment of the line switch 9 begins, and / or accelerates out of this precisely when the adjustment of the line switch 9 is finished.

[0089] In particular, the adjustment of the line switch 9 is somewhat sluggish. Furthermore, the braking and / or acceleration of the delivery piston 3a, 3b is / are somewhat sluggish. Thus, the adjustment of the line switch 9 is triggered, in particular by the control device 7, before the delivery piston 3a, 3b is in the displacement or stroke end position POVE and / or the suction or stroke end position or is stationary. Furthermore, the acceleration of the delivery piston 3a, 3b is triggered, in particular by the control device 7, before the line switch 9 is adjusted.

[0090] In particular, after the triggering of the adjustment of the line switch 9, the profile PR is determined by detecting the position variable PGa, PGb and the delivery variable FG" characteristic of the position ST of the line switch 9 and linking them together in such a way that if the building and / or thick material DS does not have the standard viscosity but a different viscosity, the delivery piston 3a, 3b brakes less or more, so that the delivery piston 3a, 3b is in the displacement or stroke end position POVE and / or the suction or stroke end position or is stationary exactly when the adjustment of the line switch 9 begins.

[0091] In particular, after the acceleration of the delivery piston 3a, 3b is triggered, the profile PR is determined by detecting the position variable PGa, PGb and the delivery variable FG" characteristic of the position ST of the line switch 9 and linking them together in such a way that if the building and / or thick material DS does not have the standard viscosity but a different viscosity, the delivery piston 3a, 3b accelerates less or more, so that the delivery piston 3a, 3b accelerates from the displacement or stroke end position POVE and / or the suction or stroke end position exactly when the adjustment of the line switch 9 is completed.

[0092] This enables low-wear and / or problem-free operation of the construction and / or thick matter pump 1 and / or as uninterrupted a pumping of construction and / or thick matter DS as possible by means of the construction and / or thick matter pump 1.

[0093] The method further comprises the step of selecting an optimization objective OZ from a set of several selectable optimization objectives OZ.
