Description
[0001] Construction material and / or thick material transport vehicle
[0002] The invention relates to a construction material and / or thick material conveying vehicle.
[0003] It is an object of the present invention to create a construction material and / or thick material conveying vehicle which has special properties. In particular, at least one support boom of the construction material and / or thick material conveying vehicle is to be improved with regard to lightweight construction and / or packaging.
[0004] This problem is solved by the subject matter of the independent patent claim. Preferred embodiments are the subject matter of the dependent patent claims. The wording of all patent claims is incorporated by express reference into the present description.
[0005] A construction material and / or high-density material conveying vehicle according to the invention comprises a chassis and at least one support boom. The support boom is designed to stabilize the chassis and prevent it from tipping over. By stabilizing the chassis with the at least one support boom, the chassis can be secured against tipping. The support boom has a foot section designed to make contact with the ground. When stabilizing the chassis and preventing it from tipping over, the foot section can contact the ground to transmit a stabilizing force. The support boom has a telescopic leg, which is designed to be length-adjustable for setting a horizontal distance between the foot section and the chassis. In particular, the telescopic leg can be retracted to adjust the foot section, thereby reducing the horizontal distance to the chassis.With the minimum horizontal distance between the foot section and the chassis set, the outrigger can be positioned for road travel of the construction material and / or bulk material transport vehicle. The telescopic leg has at least two telescopic segments that are adjustable relative to each other along a longitudinal direction of the telescopic leg. An inner and an outer section of the telescopic segments are nested. The telescopic leg also has a guide assembly designed to move the inner telescopic segment movably relative to the outer telescopic segment. The guide assembly has a guide rail that extends longitudinally along the longitudinal direction. Furthermore, the guide assembly has a guide element that is movably, and in particular slidably, guided on the guide rail.The guide rail is located on a lateral flank section of the inner telescopic segment, and the guide element is located laterally to the inner telescopic segment on a lateral flank section of the outer telescopic segment – or vice versa. In other words, the guide rail may be present on the lateral flank section of the inner telescopic segment, while the guide element is located laterally to the inner telescopic segment on a lateral flank section of the outer telescopic segment – or the guide element may be present on the lateral flank section of the inner telescopic segment, while the guide rail is located laterally to the inner telescopic segment on the lateral flank section of the outer telescopic segment.
[0006] The guide arrangement can provide additional guide surfaces for the mutually contacting circumferential surface sections of the telescopic segments, which can reduce the surface pressure acting on the circumferential surface sections to guide the telescopic segments, especially in the extended state.
[0007] In particular, the construction material and / or slurry conveying vehicle is a truck-mounted concrete pump, i.e., a self-propelled concrete pump. Alternatively, the construction material and / or slurry conveying vehicle could be a mobile, especially self-propelled, belt conveyor, which may be designed for conveying construction material in bulk form.
[0008] In this context, "thick material" refers to a paste-like mixture of different substances. Examples of thick material include mortar, cement, screed, or concrete, each in a mixable and / or pumpable state. In this mixable and / or pumpable state, the thick material is not yet hardened. Specifically, thick material is a building material. Alternatively or additionally, it can also be a bulk material.
[0009] In an embodiment of the invention, the inner telescopic segment is adjustable relative to the outer telescopic segment between an extended position and a retracted position. In the retracted position, the length of the telescopic leg is shorter than in the extended position. When the base section is unsupported, the guide element and the guide rail are pressed against each other along the direction of gravity to hold the inner telescopic segment essentially horizontally and—alternatively or additionally—parallel to the longitudinal direction of the telescopic leg. Specifically, when the base section is unsupported, the guide element and the guide rail are pressed against each other along the direction of gravity when the inner telescopic segment is in the extended position relative to the outer telescopic segment."Support contact" can mean, in particular, that there is not only a loose installation, but also an installation with the transmission of a support force. This support force can correspond to at least a portion of the weight of the construction material and / or bulk material transport vehicle.
[0010] “Support-contact-free” can mean, in particular, that there is no contact between the foot section and the ground, for example, that the foot section hangs freely.
[0011] Advantageously, the guide element and / or the guide rail can be subjected to different loads when the foot section is in contact with the ground compared to when the foot section is unsupported. For example, in some embodiments, the guide element and / or the guide rail can be relieved of load when the foot section is in contact with the ground. In other embodiments, the guide element and / or the guide rail can be subjected to the opposite load to that experienced when the foot section is unsupported.
[0012] In a further embodiment of the invention, the inner telescopic segment has a top surface section, which is in particular substantially flat. This top surface section specifically comprises a portion of the outer circumferential surface of the inner telescopic segment. The guide arrangement projects beyond the top surface section of the inner telescopic segment along the longitudinal direction of the telescopic leg towards the chassis. Conversely, the top surface section can be recessed relative to the guide arrangement along the longitudinal direction. The top surface section can form an "upper chord section" of the inner telescopic segment. This recessed top surface section relative to the guide arrangement allows for the creation of additional installation space, for example, for a cable reel for winding a hydraulic line for the hydraulic cylinders of the outrigger.In this way, despite the recessed upper section, a sufficient clamping length can be achieved in the extended position, both with a support-free foot section and with a support-contacting foot section.
[0013] In a further embodiment of the invention, the inner telescopic segment has an end section facing the chassis, particularly along the longitudinal direction. The end section of the inner telescopic segment facing the chassis diverges, particularly along the longitudinal direction, from the foot section. The inner telescopic segment has an end face at its end section facing the chassis, which is inclined, at least partially, relative to the longitudinal direction, and also relative to the direction of gravity. In particular, at least a region of the end face and a, in particular, substantially flat, underside section of the inner telescopic segment form an acute angle. The acute angle can be, in particular, a minimum of 30° and / or a maximum of 60°. For example, the acute angle can be approximately or exactly 45°.In particular, the acute angle widens in the opposite direction to gravity and away from the chassis along the longitudinal direction.
[0014] Advantageously, the underside section of the inner telescopic segment can form a portion of the outer circumferential surface of the inner telescopic segment. The underside section can form a "lower chord section" of the inner telescopic segment. The underside section can project beyond the upper section along the longitudinal direction. In particular, the underside section can terminate closer to the chassis along the longitudinal direction than the upper section. The underside section can thus project beyond the upper section towards the chassis along the longitudinal direction.
[0015] In a further embodiment of the invention, the guide element comprises a pin section. The pin section can have a non-circular and / or rectangular cross-sectional contour. In particular, a lateral through-opening is provided on the flank section of the outer telescopic segment, through which the pin section, in particular with a precise fit, extends. The pin section, in particular, has an outer circumferential guide surface section. The pin section can extend through the lateral through-opening such that the outer circumferential guide surface section of the pin section is arranged in an interior space of the outer telescopic segment in order to contact, in particular there, the guide rail present on the inner telescopic segment. An implementation of the guide element with a pin section can offer advantages with regard to ease of assembly and / or...The telescopic leg is designed to be removable, which can also prove advantageous in the event of maintenance.
[0016] In a further embodiment of the invention, the plug pin section has an outer circumferential surface which defines the cross-sectional contour of the plug pin section in a non-circular manner. The outer circumferential surface comprises the guide surface section of the plug pin section and a circumferential surface subsection opposite the guide surface section, particularly vertically. Alternatively or additionally to its convex design, the guide surface section, particularly in a cross-section of the plug pin section oriented perpendicular to a plug axis of the plug pin section, has a larger radius of curvature than the circumferential surface subsection. "Vertical" can mean parallel to the direction of gravity. "Horizontal" can mean perpendicular to the direction of gravity.
[0017] Advantageously, the circumferential surface section in the cross-section of the dowel pin section can correspond to a part, in particular a half, of an imaginary circular contour, wherein the guide surface section deviates radially inwards with respect to this circular contour such that the guide surface section and the circular contour define a crescent-shaped defect, wherein a cross-sectional area of the dowel pin section relative to an imaginary full circular area inscribed by the circular contour, in particular exactly, lacks the crescent-shaped defect.
[0018] In a further embodiment of the invention, the guide element has a flange section from which the pin section projects, in particular integrally and / or in a pin-like manner. The flange section can project radially from the pin section, particularly at least partially circumferentially. With the pin section projecting through the through-opening, the flange section is positioned on the outside against the flank section of the outer telescopic segment. In particular, with the pin section projecting through the through-opening, the flange section is not only loosely positioned on the outside against the flank section of the outer telescopic segment, but is also detachably fastened to this flank section, in particular by means of a screw connection.
[0019] In a further embodiment of the invention, the guide element has a projection. In particular, the projection has a non-circular and / or rectangular cross-sectional contour. Specifically, the projection is arranged to extend laterally outwards, and in particular is integrally arranged, on the flank section of the inner telescopic segment. The projection can extend and / or be arranged such that it contacts the guide rail present on the inner side, and in particular is integrally arranged, of the flank section of the outer telescopic segment.
[0020] In a further embodiment of the invention, the outer telescopic segment has two lateral flank sections that are opposite each other, particularly horizontally. The two lateral flank sections of the outer telescopic segment flank the inner telescopic segment. The inner telescopic segment can therefore be arranged horizontally between the two lateral flank sections of the outer telescopic segment. The inner telescopic segment has two lateral flank sections that are opposite each other, particularly horizontally. The telescopic leg has two guide assemblies that are opposite each other, particularly horizontally. In particular, the two guide assemblies flank the inner telescopic segment. The two guide assemblies can be of the same design. However, it may also be advantageous if the two guide assemblies are designed differently, for example, one with a pin section and the other with a projection.
[0021] In a further embodiment of the invention, the outer telescopic segment is mounted on the chassis, in particular so as to be pivotable about a vertical pivot axis. Alternatively or additionally, the construction material and / or thick material conveying vehicle has at least two, in particular four, support booms. Two support booms without a telescopic leg may be present.
[0022] The construction material and / or thick material conveying vehicle should ideally have at least one linear drive unit per support boom, in particular in the form of a hydraulic cylinder, for extending and retracting the respective telescopic leg.
[0023] In a further embodiment of the invention, the construction material and / or slurry conveying vehicle is designed as a truck-mounted concrete pump and has a distributor mast that is adjustable relative to the chassis for distributing the conveyed construction material and / or slurry. A conveying line through which the conveyed construction material and / or slurry can flow can be routed from the chassis along the distributor mast and / or terminate at a free end of the distributor mast.
[0024] In a further, particularly alternative, embodiment of the invention, the construction material and / or thick material conveying vehicle is designed as a mobile belt conveyor and has a conveyor belt device that is telescopic relative to the chassis.
[0025] Further advantages and features of the invention will become apparent from the claims and from the following description of preferred embodiments of the invention, which are illustrated with reference to the drawings. Reference numerals refer to identical, similar, or functionally equivalent components.

[0034] A construction material and / or viscous material transport vehicle 1 is designed for conveying construction material and / or viscous materials, particularly in the form of concrete. The construction material and / or viscous material transport vehicle 1 can be mobile, allowing it to be moved to a construction site and used there temporarily and / or for the conveying of construction material and / or viscous materials.
[0035] The construction material and / or viscous material conveying vehicle 1 can be a self-propelled work machine. According to Fig. 1, the construction material and / or viscous material conveying vehicle 1 is, for example, a truck-mounted concrete pump 2. In other embodiments, the construction material and / or viscous material conveying vehicle 1 can, for example, be designed as a mobile belt conveyor, in particular for conveying bulk materials.
[0036] The construction material and / or thick material conveying vehicle 1 has a chassis 3. The chassis 3 can be a commercial vehicle chassis, in particular, as in the present case, a truck chassis. The construction material and / or thick material conveying vehicle 1 has at least one support boom 4, which is designed to support the chassis 3 against tipping, in particular overturning. The construction material and / or thick material conveying vehicle 1 can have at least two support booms 4. In the present case, the construction material and / or thick material conveying vehicle 1 has four such support booms 4, of which two are arranged substantially diagonally opposite each other.
[0037] The support arms 4 each have a foot section 5. The foot section 5 is designed to contact a ground U for anti-tipping bracing. The foot section 5 can serve to transfer part of the weight of the construction material and / or high-strength material transport vehicle 1 and / or to transfer at least part of a tipping moment into the ground U.
[0038] At least two of the outriggers 4 each have a telescopic leg 6. The telescopic leg 6 is designed to be length-adjustable for setting a horizontal distance HA between the base section 5 and the chassis 3. By adjusting the length of the telescopic leg 6, the horizontal distance HA can be varied. The telescopic leg 6 can connect the base section 5 to the chassis 3. The horizontal distance HA is measured horizontally. "Horizontal" can mean perpendicular to the direction of gravity G. "Vertical" can mean parallel to the direction of gravity G.
[0039] In particular, there are embodiments in which at least one non-length-adjustable, especially non-telescopic, additional support boom is provided. Specifically, such a non-length-adjustable additional support boom can be pivoted laterally to adjust a horizontal distance HA between the relevant foot section 5 and the chassis 3. For example, two length-adjustable support booms 4 and two non-length-adjustable additional support booms may be provided.
[0040] The telescopic leg 6 of the respective support boom 4 has at least two, in this case exactly two, telescopic segments 7. The telescopic segments 7 are adjustable relative to each other along a longitudinal extension direction L of the respective telescopic leg 6. Of the telescopic segments 7 of the respective telescopic leg 6, an inner telescopic segment 7, 8 and an outer telescopic segment 7, 9 are arranged nested. The telescopic leg 6 has a guide arrangement 10, which serves to adjustably guide its inner telescopic segment 7, 8 relative to its outer telescopic segment 7, 9.
[0041] The guide arrangement 10 has a guide rail 11 that extends longitudinally along the longitudinal direction L of the respective telescopic leg 6. The guide arrangement 10 also has a guide element 12 that is movably guided on the guide rail 11. In particular, the guide element 12 is guided on the associated guide rail 11 along the longitudinal direction L, for example by sliding or rolling motion. The guide rail 11 is, for example, located on a lateral flank section 13 of the inner telescopic segment 7, 8, while the guide element 12 is located laterally to the inner telescopic segment 7, 8 on a lateral flank section 13 of the outer telescopic segment 7, 9, cf. illustrations in Figs. 4 and 5.Alternatively, the guide element 12 can also be located on the lateral flank section 13 of the inner telescopic segment 7, 8, while the guide rail 11 is located laterally to the inner telescopic segment 7, 8 on the lateral flank section 13 of the outer telescopic segment 7, 9, cf. illustrations in Figs. 6 and 7.
[0042] For example, the inner telescopic segment 7, 8 is adjustable relative to the outer telescopic segment 7, 9 between an extended position SA and a retracted position SE, as can be seen particularly in the illustrations of Figs. 2 and 3. In the retracted position SE, the length LB of the telescopic leg 6 is less than in the extended position SA.
[0043] The inner telescopic segment 7, 8 and / or the outer telescopic segment 7, 9 may be made of steel.
[0044] For example, particularly in the extended position SA, the guide element 12 and the guide rail 11 are in contact with each other along the direction of gravity G when the associated foot section 5 is not used for support. If the foot section 5 is not used for support, it can be free of contact with the support.
[0045] For example, the guide element 12 and the guide rail 11 can be pressed together along the direction of gravity G, with the support section 5 free from contact with the support. As a result of the guide element 12 and the guide rail 11 being pressed together with the support section 5 free from contact with the support, the inner telescopic segment 7, 8 can be held essentially horizontally and / or parallel to the longitudinal extension direction L of the respective telescopic leg 6. In particular, this prevents the respective telescopic leg 6 or inner telescopic segment 7, 8 from "winging out".
[0046] When the foot section 5 is in contact with the support surface U, the guide element 12 and / or the guide rail 11 can be subjected to a different load than when the foot section 5 is not in contact with the support surface. For example, in some embodiments, the guide element 12 and / or the guide rail 11 can be relieved of load when the foot section 5 is in contact with the support surface U. This can be the case in the example shown in Figures 4 and 5. In other embodiments, the guide element 12 and / or the guide rail 11 can be subjected to a load opposite to that experienced when the foot section 5 is not in contact with the support surface U. This can again be the case in the example shown in Figures 6 and 7.
[0047] In this case, the inner telescopic segment 7, 8 has an upper section 14. The upper section 14 can be essentially planar. The upper section 14 can be referred to as the upper chord section of the inner telescopic segment 7, 8. In this case, the guide arrangement 10 projects beyond the upper section 14 along the longitudinal direction L towards the chassis 3, in particular towards a machine center of the construction material and / or thick material conveying vehicle 1.
[0048] Due to the recessed upper surface section 14 relative to the guide arrangement 10, installation space can be gained – as in the present case – for example, for a cable reel for winding up a hydraulic line for the hydraulic cylinders of the support boom 4. In this way, a sufficient clamping length can be achieved in the extended position SA, particularly despite the recessed upper surface section 14, both with the foot section 5 not touching the support and with the foot section 5 touching the support.
[0049] The inner telescopic segment 7, 8 has an end face 16 at its end section 15 facing the chassis 3, in particular the center of the machine. The end face 16 is inclined, at least in some areas, with respect to the longitudinal direction L and the direction of gravity G. At least a portion of the end face 16 and a subside section 17 of the inner telescopic segment 7, 8, which is substantially planar, form an acute angle α. The acute angle α tapers, in particular, towards the center of the machine. The acute angle α can be, for example, 30° to 60°. In this case, the acute angle α is approximately 45°.
[0050] The underside section 17 of the inner telescopic segment 7, 8 can be referred to as the lower chord section of the inner telescopic segment 7, 8. The underside section 17 can run substantially parallel to the upper section 14. The underside section 17 can extend along the longitudinal direction L beyond an end of the upper section 14 facing the chassis 3.
[0051] For example, the guide element 12 has a plug-in pin section 18. The plug-in pin section 18 can have a non-circular cross-sectional contour 19. A lateral through-opening 20 can be present on the outer telescopic segment 7, 9. The plug-in pin section 18 projects through the through-opening 20 such that an outer circumferential guide surface section 21 of the plug-in pin section 18 is arranged in an interior space 22 of the outer telescopic segment 7, 9 in order to contact the guide rail 11 present on the inner telescopic segment 7, 8, see in particular the illustration in Fig. 4. The plug-in pin section 18 is inserted into the through-opening 20, for example, in a direction perpendicular to the longitudinal extension direction L and horizontally. The cross-sectional contour 19 extends, in particular, in a plane orthogonal to the insertion direction.
[0052] For example, the plug pin section 18 has an outer circumferential surface 23 that defines the cross-sectional contour 19 of the plug pin section 18 in a non-circular manner. The outer circumferential surface 23 can include both the guide surface section 21 and a circumferential surface subsection 24 that is opposite the guide surface section 21, particularly vertically and / or diametrically. In this case, the guide surface section 21 is convex. Alternatively or additionally, the guide surface section 21 can – as in this case – have a larger radius of curvature than the circumferential surface subsection 24, particularly in a cross-section of the plug pin section 18 shown in Fig. 5.
[0053] For example, in the cross-section of the dowel pin section 18, the circumferential surface subsection 24 can correspond to a part, in particular half, of an imaginary circular contour. The guide surface section 21 can deviate radially inwards with respect to this circular contour such that the guide surface section 21 and the circular contour define a crescent-shaped defect. A cross-sectional area of the dowel pin section 18 can, relative to an imaginary full circle inscribed by the circular contour, specifically lack this crescent-shaped defect.
[0054] The guide element 12 can have a flange section 25 from which the pin section 18 projects. For example, the pin section 18 can project integrally and / or tenon-like from the flange section 25. The flange section 25 can project radially with respect to, in particular the extension direction, the pin section 18. The flange section 25 is, for example, located on the outside of the flank section 13 of the outer telescopic segment 7, 9 when the pin section 18 extends through the through-opening 20, see in particular the illustration in Fig. 4. The flank section 13 can be detachably attached to this flank section 13 of the outer telescopic segment 7, 9, for example by means of a screw connection. For example, the guide element 12 has a projection 26, see in particular the illustrations in Figs. 6 and 7. The projection 26 can have a non-circular cross-sectional contour 19.
[0055] A non-circular cross-sectional contour 19 can be rectangular, for example, as an alternative to the cross-sectional contour 19 of the plug-in section 19 realized in Figs. 4 and 5.
[0056] For example, the projection 26 is arranged on the flank section 13 of the inner telescopic segment 7, 8, as can be seen particularly clearly in the illustration according to Fig. 6. The projection 26 can be arranged to project laterally outwards from the flank section 13 of the inner telescopic segment 7, 8. The projection 26 can be integrally present on the flank section 13 of the inner telescopic segment 7, 8. In the present case, the projection 26 projects laterally outwards from the flank section 13 of the inner telescopic segment 7, 8 such that the projection 26 contacts the guide rail 11 present on the inside of the flank section 13 of the outer telescopic segment 8, 9. The guide rail 11 can be integrally present on the inside of the flank section 13 of the outer telescopic segment 8, 9.
[0057] The outer telescopic segment 7, 9 of each telescopic leg 6, for example, has two lateral flank sections 13, which are arranged opposite each other – in this case horizontally and perpendicular to the longitudinal direction L. The two lateral flank sections 13 of the outer telescopic segment 7, 9 flank the associated inner telescopic segment 7, 8. The inner telescopic segment 7, 8 can be positioned between the two flank sections 13 of the outer telescopic segment 7, 9 in order to retract into the outer telescopic segment 7, 9.
[0058] The inner telescopic segment 7, 8 has two lateral flank sections 13 opposite each other, in this case horizontally and perpendicularly to the longitudinal direction L. The telescopic leg 6 in question can have two guide arrangements 10 opposite each other, in particular horizontally and perpendicularly to the longitudinal direction L, each of which is arranged in the area of a joint between flank sections 13 of the inner telescopic segment 7, 8 and the outer telescopic segment 7, 9 that face each other directly.
[0059] The outer telescopic segment 7, 9 can be designed as a hollow profile body. Alternatively or additionally, the inner telescopic segment 7, 8 – as in the present case – can be designed as a hollow profile body. The inner telescopic segment 7, 8 and / or the outer telescopic segment 7, 9 can have a longitudinally extending cavity in the longitudinal direction L, which in particular has a substantially rectangular cross-section.
[0060] For example, the outer telescopic segment 7, 9 of a corresponding telescopic leg 6 is mounted on the chassis 3. The respective outer telescopic segment 7, 9 is pivotally adjustable about a vertical pivot axis VS relative to the chassis 3.
[0061] The construction material and / or thick material conveying vehicle 1, for example, has a distribution mast 27 that is adjustable relative to the chassis 3 and is designed for distributing conveyed construction material and / or thick material. The distribution mast 27 can be mounted on the chassis 3 so that it can be rotated about a vertical axis of rotation by means of a rotary mechanism of the construction material and / or thick material conveying vehicle 1. The distribution mast 27 can be designed as a multi-jointed articulated arm. The distribution mast 27 can have a number of arm segments that are connected and controllable by means of a number of hinge joints in the manner of a serial robot.
[0062] Supporting the chassis 3 by means of at least one support boom 4 can counteract a shift in the center of gravity when adjusting and / or moving the distributor mast 27, thus preventing it from tipping over.
[0063] The construction material and / or viscous material conveying vehicle 1 has a conveying line 28 through which the conveyed construction material and / or viscous material flows. The conveying line 28 runs from the chassis 3 along the distribution mast 27. The conveying line 28 can terminate at a free end 29 of the distribution mast 27, as shown here. The conveying line 28 can be connected to a construction material and / or viscous material pumping unit supported by the chassis 3 for conveying construction material and / or viscous material.
[0064] The delivery line 28 is connected, in particular, to a pressure port of the construction and / or viscous material pumping unit. Advantageously, the construction and / or viscous material pumping unit can have at least one delivery cylinder with a variable-volume delivery chamber. For example, two delivery cylinders, each with a variable-volume delivery chamber, are provided, the volumes of which can be changed in opposite directions by adjusting the associated delivery pistons. The construction and / or viscous material pumping unit has, for example, a pipe diverter, in particular with an S-shaped S-pipe. The pipe diverter can be fluid-conductingly connected to the pressure port, which serves as the pump outlet. The pipe diverter can be arranged in a storage chamber for construction and / or viscous material, which can be filled from above. The pipe diverter can be rotatably mounted on the pressure port within the storage chamber. The at least one variable-volume delivery chamber can open into the storage chamber.The pipe diverter can be pivoted within the storage chamber relative to the at least one conveying chamber in such a way that it alternately connects and disconnects the at least one conveying chamber to the discharge port. In this way, the interplay between the pivoting of the pipe diverter and a change in the volume of the at least one conveying chamber in the storage chamber allows construction material and / or viscous material located there to be drawn in by the at least one conveying chamber and pumped through the pipe diverter and out through the discharge port. An agitator can be arranged in the storage chamber of the construction material and / or viscous material pumping unit.
