Definitions

  • the present invention relates to a thick matter pump, in particular a concrete pump, according to the preamble of claim 1.
  • Different types of mobile and stationary concrete pumps are known from the prior art, which can be equipped with a chassis.
  • Such concrete pumps can be self-propelled (e.g. truck-mounted concrete pumps or crawler concrete pumps) or can be pulled or otherwise moved.
  • the pump system or pump structure is mounted on a standard carrier chassis and combined with a distribution boom.
  • Mobile concrete pumps without a distribution boom typically include a pump structure, which includes the actual pump device or pump, a feed hopper for feeding thick matter and a delivery line into which the thick matter is pumped, and is mounted on a chassis.
  • the chassis For example, it can be a crawler chassis or a trailer axle with wheels.
  • stationary concrete pumps with a chassis and a pump structure mounted on it are also known.
  • the present invention is therefore based on the object of providing a thick matter pump of the type mentioned at the outset, whose pump structure is less bulky or makes optimal use of the space occupied and whose pump device is more accessible for maintenance and control work.
  • a thick matter pump in particular a concrete pump, which has a chassis and a pump structure attached to the chassis with a pump device for conveying Thick matter, especially concrete, includes.
  • the pump device is arranged laterally offset from the longitudinal axis of the chassis, with the overall width of the thick matter pump being limited on one side, preferably on both sides, by the pump structure.
  • the chassis can include a chassis frame or a frame structure for accommodating machine elements such as chassis components.
  • the undercarriage can, for example, be a crawler undercarriage with several (in particular two) crawler undercarriage vessels or a trailer undercarriage with at least one wheel axle.
  • the idea according to the invention is therefore to arrange the pump device off-center on the chassis, so that the longitudinal axis of the pump device is spaced from the longitudinal axis of the chassis.
  • the longitudinal axes are laterally offset and preferably run parallel to one another.
  • the vehicle frame does not protrude beyond the outer contour of the pump structure.
  • the longitudinal axis of the chassis can correspond to the longitudinal axis of a chassis frame or a frame structure of the chassis.
  • the longitudinal axes of the chassis and the pump structure are, in particular, their central axes.
  • the pump device represents the actual "pump” of the construction machine, referred to here as a "thick matter pump", by means of which the thick matter is conveyed or pumped, and can, for example, in addition to a pump unit for sucking and pumping thick matter, other elements such as a drive unit for supplying energy to the pump device, include a feed hopper and/or a delivery line.
  • a pump device for supplying energy to the pump device, includes a feed hopper and/or a delivery line.
  • the actual pump is therefore referred to here as a “pump device”, whereas the terms “thick matter pump” or “concrete pump” stand for the entire construction machine.
  • the off-center installation of the pump device means that its assembly and inspection points are moved to one side of the vehicle and are therefore much more accessible from the outside than before - the machine design of the thick matter pump is easier to assemble and service.
  • the limitation of the overall width by the pump structure also ensures in particular that the maintenance and operating personnel have direct access to the maintenance and control points and that the frame structure or the chassis does not hinder this access.
  • the off-center arrangement of the pump device also enables better access to maintenance and service points of any internal combustion engine of the thick matter pump, for example for changing filters or oil, due to the narrower overall machine.
  • the motor is moved to the same side of the thick matter pump as the pump device.
  • the space-saving component arrangement resulting from the off-center arrangement of the pump device can also be advantageous when transporting the thick matter pump, for example on a truck or in an ISO sea container.
  • the off-center arrangement of the pump device results in an increase in larger installation space on the side of the thick matter pump, from which the pump device moves away - for example usable to accommodate other required large components of the pump structure or space-consuming machine elements of the thick matter pump such as motor(s), cooler or tank ( s).
  • the installation space Through clever use of the installation space, the dimensions of the entire machine can be further reduced, which brings with it an increase in clarity and safety when moving the thick matter pump on the construction site.
  • the machine height can also be reduced through clever use of installation space, which is advantageous, for example, in terms of clarity when driving with a remote control.
  • the entire pump structure can be arranged essentially centrally on the chassis.
  • the pump structure may comprise a housing in which the pump device is accommodated, the housing sitting centrally on the chassis and the pump device being arranged off-center with respect to the longitudinal axis of the housing.
  • the pump device can include one or more delivery cylinders, which pump thick matter into a delivery line and are in particular hydraulically driven.
  • the delivery cylinder or cylinders preferably run parallel to the longitudinal axis of the pump device.
  • the thick matter pump can be designed as a caterpillar thick matter pump with a crawler chassis, which can, for example, include two chassis ships or caterpillar ships. In this embodiment, which is particularly suitable for use on construction sites when the working position is changed frequently, the thick matter pump can be remotely controlled.
  • the thick matter pump can be designed as a trailer pump with preferably two (or more) wheels and a trailer coupling. Additional support feet can be provided here on the chassis for stable storage of the thick matter pump during use.
  • the pump structure comprises a feed funnel for supplying thick matter to the pump device, the overall width of the thick matter pump being limited on one side by the feed funnel.
  • the feeding funnel is generally a thick matter collection container which, despite its name, does not necessarily have to be funnel-shaped, but is preferably so.
  • the feed funnel is preferably arranged centrally to the longitudinal axis of the pump device.
  • the longitudinal axes of the pump device and the feed hopper can coincide here, although it should be noted that the feed hopper does not have to be symmetrical.
  • the feed hopper is preferably on a rough scale, ie essentially symmetrical.
  • the overall width of the thick matter pump can be limited on one side by a wall of the feed hopper or by a component connected to it and, in this case, part of the feed hopper, such as an agitator motor.
  • the pump structure comprises a delivery line into which thick matter can be conveyed by means of the pump device.
  • the delivery line runs laterally along the thick matter pump from back to front and is preferably connected to or connected to a rear wall of the feed hopper via a folding arch that can be opened in particular.
  • the total width of the thick matter pump is limited on one side by the delivery line. The latter is in particular a pipeline.
  • the delivery line can run on the side of the thick matter pump to which the pump device has moved due to its off-center placement. However, it preferably runs on the opposite side of the thick matter pump. Furthermore, the delivery line can have a connection at the front for a further thick material line, for example a delivery hose line.
  • the total width of the thick matter pump is limited on one side by the feed hopper and on the other side by the delivery line.
  • the pump structure or the pump device thus moves as close as possible to the side of the thick matter pump, so that the operating and maintenance personnel can reach the maintenance points of the pump device comfortably and without having to bend over the chassis or other protruding parts of the thick matter pump. Furthermore, there are no unnecessary overhangs, but the installation space is optimally used, so that there is a better overview on the construction site.
  • a tank, a motor and / or a storage tank is arranged, which does not protrude laterally beyond the delivery line and which preferably lies between the pump device and the delivery line is arranged.
  • other large components such as a device, parts and/or tool box for the thick matter pump can also be arranged there.
  • the off-center arrangement of the pump device frees up installation space, in particular between the pump device and the delivery line running on the outside, which can conveniently be used to accommodate bulky components of the thick matter pump.
  • the components may be housed in a common housing with the pump device or in a separate housing or housings.
  • the pump structure does not protrude beyond the chassis on one side, preferably on both sides (i.e. does not have an overhang).
  • the maximum width of the pump structure corresponds to the maximum width of the chassis, so that there are no overhangs on either side due to the pump structure or the delivery line and the feed hopper.
  • the machine width i.e. the width of the thick matter pump, corresponds to the width of the pump structure (including feed hopper and delivery line).
  • the pump device comprises two delivery cylinders connected to the feed hopper, which can be driven in such a way that one delivery cylinder carries out a suction stroke and sucks thick matter out of the feed hopper, while at the same time the other delivery cylinder carries out a pump stroke and feeds thick matter into the Delivery line pumps.
  • the delivery cylinders are preferably hydraulically driven.
  • the delivery cylinders are preferably connected to a front wall of the feed hopper, which is opposite the rear wall into which the delivery line opens.
  • One or more agitators for forced feeding can also be installed in the feed hopper of the thick matter stored therein can be provided to the suction openings of the delivery cylinders.
  • the pump structure comprises a pipe switch, which is preferably pivotally mounted on the feed hopper and which can be driven in such a way that it alternately connects the delivery line to the delivery cylinder, which each carries out a pump stroke.
  • the pipe switch can be designed as an S-pipe and is preferably located inside the feed hopper. It can be driven or pivoted back and forth by means of one or more hydraulic swivel cylinders.
  • the pump device comprises a water tank for visual inspection and maintenance of at least one delivery cylinder of the pump device, the pump device being arranged and designed in such a way that the water tank can be seen and accessed from outside the thick matter pump.
  • the water tank is in particular openable and forms a control and maintenance point of the pump device, which is arranged in the area of the side of the thick matter pump due to its off-center arrangement and is therefore easily accessible. For example, system leaks can be discovered using the openable water tank or wear parts of the delivery cylinders such as their delivery pistons can be replaced or repaired.
  • the pump device is at least partially arranged in a housing of the pump structure and is preferably arranged laterally offset from the longitudinal axis of the housing.
  • the housing can therefore sit centrally on the chassis, while the pump device is arranged off-center to the chassis and the housing.
  • the housing ensures noise reduction and protection from environmental conditions or weather and can be designed as a sheet metal housing. It may have one or more flaps to provide access to one or more maintenance and/or operating points.
  • a ventilation grille can be provided for sucking in or blowing out air for cooling.
  • the thick matter pump can also have a control station, in particular arranged laterally, for operating the thick matter pump.
  • the control station is preferably arranged in such a way that it does not protrude beyond the pump structure, in particular not beyond the feed hopper or the delivery line.
  • the undercarriage is a crawler undercarriage with two crawler undercarriage ships.
  • the pump structure extends into an area above one or more crawler ships. Due to the eccentricity of the pump structure according to the invention, the sometimes generally unused installation space above the crawler chassis can be used for the pump structure.
  • the thick matter pump comprises a maintenance point, in particular a water tank of the pump device, and/or an energy generation unit, for example a motor (combustion engine or electric motor) and/or a battery, and/or a control cabinet and/or another machine component, for example an access for a battery disconnector, a jump starter or an ignition, and/or a storage space, for example a toolbox, a storage box or a radio remote control tray, which is/are accessible from a single side of the thick matter pump, in particular on a side limited by the pump structure .
  • the thick matter pump can include a lashing device for attachment to/in a container.
  • the Figure 1 shows a preferred embodiment of the thick matter pump 10 according to the invention in a side view.
  • a horizontal section through the thick matter pump 10 at the level of line AA is in the Figure 2 shown in a top view.
  • the thick matter pump 10 is a crawler concrete pump (in the sense of a self-propelled mobile concrete pump without a distribution boom) with two crawler chassis ships 14, which are connected to a frame structure 12, in particular designed as a steel frame, which, like the crawler chassis ships 14, is part of the Chassis of the thick matter pump 10 is.
  • a frame structure 12 does not necessarily have to be provided.
  • the thick matter to be conveyed here: concrete
  • the thick matter to be conveyed can be filled into the funnel-shaped feed hopper 22 via an upper opening, which is pumped into the delivery line 24 by means of the pump device 20 and transported to the place of use becomes.
  • the pump device 20 which in the Figure 2 can be seen, comprises two delivery cylinders 30 running parallel to the longitudinal axis L1 of the chassis, which are connected to a front wall of the feed hopper 22 and each include an axially displaceably mounted delivery piston.
  • the delivery cylinders 30 can be driven hydraulically via drive cylinders 32 in such a way that one of the delivery cylinders 30 sucks concrete from the feed hopper 22 (suction stroke), while the other delivery cylinder 30 pumps the previously sucked concrete into the delivery line 24 (pump stroke).
  • the suction and pump strokes alternate with each delivery cylinder 30.
  • a pipe switch which is pivotably mounted in the loading funnel 22, is synchronized with the pumping and suction strokes of the delivery cylinders 30 in such a way that it connects the delivery cylinder 30, which is currently executing a pumping stroke, with the delivery line 24, which opens into the rear wall of the loading funnel 22 opposite the front wall.
  • the feed hopper 22 includes two laterally arranged agitators 28, which mix the concrete and move it to the conveyor cylinders 30.
  • on the underside of the loading hopper 22 there is also an opening 23 which can be closed by a lockable flap for quickly emptying the loading hopper 22.
  • the axially movable delivery pistons are each connected to the associated drive cylinder 32 via a piston rod.
  • the front sides of the delivery pistons come into contact with the concrete, while the chambers of the delivery cylinders 30 facing away from the concrete are filled with water.
  • a common water tank 34 is arranged between the delivery cylinders 30 and the drive cylinders 32, through which the piston rods of the delivery pistons run.
  • the water in the water tank 34 moves in alternating delivery mode between the two delivery cylinders 30 and is in contact with the backs of the delivery pistons facing away from the loading funnel 22. In addition to cooling the delivery cylinders, this also serves to provide a maintenance point for the pump device 20 that is easily accessible by opening the water tank 34 and through which, for example, the delivery pistons can be serviced or replaced.
  • the pump structure and also the pump device are usually arranged centrally to the longitudinal axis of the chassis.
  • the central position almost necessarily results from the free space between the vehicle or body frame for installation.
  • the aim is to have a central center of gravity for the road-moving device.
  • the center of gravity of the concrete pump can be achieved, for example, by appropriately positioning other heavy machine elements (tanks, coolers). Access to the water tank of the pump device is ensured via appropriate platforms and free spaces above the water tank.
  • the pump structure is generally not important for truck-mounted concrete pumps.
  • the pump device 20 is therefore arranged off-center, ie laterally offset from the longitudinal axis L1 of the chassis (which in the exemplary embodiment shown also corresponds to the longitudinal axis of the frame structure 12).
  • the longitudinal axis L2 of the pump device 20 which runs parallel to and centrally between the delivery cylinders 30 and, in this exemplary embodiment, centrally (in plan view) through the feed funnel 22, has a clear offset or distance from the longitudinal axis L1 of the chassis ( see. Figure 2 ).
  • the housing 18 is arranged centrally to the longitudinal axis L1, so that the pump device 20 is also offset from the surrounding housing 18 or arranged off-center.
  • the pump device 20 and the feed hopper 22 move completely to one side (in the Figure 2 upward) of the thick matter pump 10, so that the corresponding side wall of the feed hopper 22 limits the width of the thick matter pump 10 on this side.
  • the width of the chassis essentially corresponds to the width of the entire pump structure 16 (i.e including feed hopper 22 and delivery line 24). This results in better access to the maintenance points of the pump structure 16 and a more compact structure of the thick matter pump 10, which leads to better clarity on the construction site.
  • the space 40 freed up by the off-center arrangement of the pump device 20 between the pump structure 20 and the delivery line 24 (cf. the hatched area 40 in the Figure 2 ), which in the present exemplary embodiment lies within the housing 18, but does not have to, for additional components of the thick matter pump 10.
  • These can be large components such as tanks, engines or storage units, or simply storage space for parts, tools or the like.
  • the off-center arrangement of the pump structure 20 according to the invention is not limited to crawler concrete pumps and trailer concrete pumps and can also be used, for example, in stationary concrete pumps.
