Definitions

  • the invention relates to a two-chamber disposal container, in particular of disposal vehicles, with an axially displaceable ejection piston, which separates its first chamber, which is designed as a suction chamber and has an openable lid, from the second chamber, which is designed as a pressure chamber, with one of which has inwardly directed stops for stopping the Moving ejection piston provided container wall guided sleeve, the lumen is closed with a shut-off plate and which cooperates with the inside of the container wall guide and sealing means.
  • This suction chamber serves as a collecting container for the media to be accommodated
  • the front chamber facing the driver's cab is used as a pressure chamber for moving the ejection piston, an overpressure meaning a movement towards the rear end of the container and thus causing the material to be ejected while being applied Vacuum, the ejection piston is pulled back into its normal position.
  • the pressure chamber is connected to a vacuum or compressed air pump by separate suction and compressed air lines; the suction chamber is connected to the vacuum pump via a separate suction line.
  • Corresponding changeover valves in the assigned lines are switched so that the suction chamber is under vacuum during suction operation and no overpressure is built up in the pressure chamber, that the pressure chamber is pressurized when ejecting, and that finally after the ejection of the piston by vacuum in the pressure chamber is withdrawn.
  • a separate shut-off valve is provided in each of the lines, which makes it possible to control the pressure in each of the two chambers independently of one another.
  • the speed that the ejection piston can assume in the event of such an uncontrolled exit is 30 m / s and, with the impulse of around 250,000 Nm, represents a considerable risk to people and material in the area.
  • Such incidents are also caused by operating errors and - as has been shown in practice - the previously known safety measures are not sufficient to bring the sliding movement of the ejection piston under control and to stop it safely.
  • EP 0 294 607 A1 describes an axially displaceable ejection piston for a two-chamber container of a disposal vehicle for receiving the sucked-in sludge.
  • This ejection piston separates its first chamber, which is designed as a suction chamber and has an openable lid, from the second chamber, which is designed as a pressure chamber, and is designed as a sleeve which is guided by the wall of the container with play and is provided with a shut-off plate which closes the lumen and connects to the pressure chamber and the suction chamber end between the outside of the sleeve and the inside of the container wall arranged guide means, and has at least one sealing profile ring between them.
  • At least one sealing profile ring preferably that assigned to the end on the suction chamber side, has a seal that can be inflated by means of a pressure fluid.
  • the inside of the wall of the container is provided with inwardly directed stops for stopping the moving discharge piston.
  • the ejection piston is set in motion by the overpressure of a pressure medium generated in the pressure chamber of the container to squeeze out the absorbed sludge and is stopped when it reaches its permissible end position.
  • This stopping is done by limiting the driving force by pressure monitoring, limit pressure gauge or the like, or by Elimination of the overpressure acting as the driving force, for example by means of a pressure relief opening in the shut-off plate that can be torn open with a tear chain or opened with a detonating pill, or stop stops that limit the path length, such as a tie rod or inward-facing stops on the inside of the wall of the container.
  • a compressible attachment is proposed which extends the sleeve towards the ejection side.
  • the object of the invention is to avoid these disadvantages and to further develop the ejection piston in such a way that the ejection piston is safely stopped and the kinetic to be implemented in the process Energy is intercepted without damage to the container wall, the ejection piston should come as close as possible to the end of the suction chamber.
  • the sleeve be provided with at least one damping member, with a brake stop corresponding to the damping members being provided on the wall of the receptacle, which interact with them.
  • This damping element or damping elements is / are designed as alternatives as hydraulically or pneumatically operating cylinders; in another alternative, the damping members are compression springs, elastic buffers or the like. These alternatives have in common that the sudden introduction of a large force is flattened with a large jerk (d3 s / d t3). The energy transferred to the hydraulic cylinder is destroyed while the compression spring stores the energy.
  • the pneumatic cylinder can be designed in such a way that the energy input causing a pressure increase in a memory is not lost due to the increased pressure, but is available for later use; this also applies in particular to a gas pressure cushion with which a hydraulic cylinder can be equipped.
  • the pneumatic cylinder can be designed in such a way that the energy taken over by it is not "lost" but is stored for later use.
  • the brake stop (s) interacting with the damping member (s) are advantageously designed in one embodiment as bolts which are directed radially inward approximately at right angles to the wall of the disposal container and are preferably connected to them, in particular with a rectangular cross section, in a simple manner can be exchanged if the discharge piston should actually have crossed the safety limit.
  • the brake stop (s) are / are designed as radially inwardly directed, preferably inserted into a circumferential groove and connected to the wall, approximately perpendicular to the wall of the two-chamber disposal container, the shaped parts being adapted to the curvature of the wall Extend fittings over a certain angular range. This extension over a certain angular range takes into account the fact that the axial movement of the ejection piston could be superimposed on a rotation, so that the location of the impact of the part of the damping element interacting with the brake stop could be shifted.
  • the damping member (s) are provided in the region of the upper vertex of the ejection piston and the brake stop (s) correspond to this in the region of the upper vertex of the disposal container, and are preferably arranged in or symmetrically to the 12 o'clock position. If only one attenuator is provided, it should be in the 12 o'clock position; in the case of several attenuators, these are located on either side of the apex or - if an odd number is present - on both sides of the apex and on top of it; preferably, the two sides of the apex are arranged in a 1 to 3 o'clock and a 9 to 11 o'clock position.
  • the position of the attenuators is specified in an area that is usually not filled with dangerous goods. This also protects these attenuators from corrosion attacks or sticking that can never be ruled out in the hazardous goods area; in this arrangement they will remain functional.
  • a preferred embodiment with a limitation of the path of the ejection piston also in the direction of the driver's cab, i.e. when retracting by means of negative pressure in the pressure chamber, is given in that the cylinder (s) as a double-acting cylinder (s) with piston rod (s) led out on both sides is / are, and that the two-chamber disposal container on the pressure chamber side corresponding to it / has the / the piston rod (s) interacting / -de brake stop (s).
  • Such a cylinder has piston rods on both sides, one of which interacts with the brake stops on the suction chamber side, the other with brake stops provided on the pressure chamber side.
  • Hydraulically or pneumatically operating cylinders behave in such a way that a slow movement is absorbed by them (almost) without force, so that the provided damping cylinders can only insignificantly hinder the movement of the ejection piston during normal operation.
  • hydraulic cylinders in particular behave almost like rigid bodies; it is therefore advantageous if an additional damping element is assigned to the hydraulically operating cylinders.
  • This damping element can be a gas cushion in the cylinder, but it can also be designed as a compression spring that interacts with the piston rod, thereby alleviating the "rigidity". In both cases, the time course of the force input into the hydraulic cylinder is flattened in such a way that it can function properly.
  • the guide means of the ejection piston are designed as guide strips which are preferably uniformly distributed over the circumference of the sleeve of the ejection piston. These guide strips running in the direction of movement - for example 8 pieces at an angular distance of 45 ° - are sufficient for guiding the ejection piston to hold the piston in its central position. These guide strips effectively reduce the risk of the discharge piston jamming and jamming; furthermore, there is no need for a guide profile which is complex in terms of production technology and which is placed around the sleeve and welded to it becomes.
  • the guide strips can also be inserted in a simple manner by means of screwing, so that the guide strips, which are always subject to wear and tear and are also subject to corrosion, can also be replaced in a simple manner.
  • the suction chamber-side seal is arranged in an annular seal receptacle made of a C-profile placed in front of the sleeve, the bottom of the seal receptacle preferably being offset to the outside relative to the sleeve.
  • This arrangement of the profile for receiving the seal ensures that the sleeve can be brought closer to the inner wall of the container without reducing the height of the seal.
  • the lever arm of the stop stops can thus also be reduced, so that the torque exerted on the clamping point of the stop stop on the container wall is reduced by a force acting on its free end.
  • the seal lying in the C-profile is supported except for a small gap from the side walls of the profile, so that the risk of the seal "tipping over" is eliminated.
  • the sleeve of the ejection piston advantageously has a deformable area in the region of the ejection side for the consumption of kinetic energy.
  • This deformable region which is preferably designed as a corrugated compression ring, interacts with the stop stops arranged at the edge of the disposal container, these stop stops preferably being arranged outside the sole region of the disposal container.
  • This pre-corrugated ring serves as a "crumple zone", which converts at least part of the kinetic energy of the moving ejection pistons into deformation work when striking the stop stops and thus destroys them.
  • stop stops are advantageously arranged in addition to the brake stop (s) of the damping member (s) so that the ejection piston can first use up the entire path length for braking via the damping member interacting with the brake stop, until the stop stops are reached and still exist Residual energy as deformation work is consumed. This is achieved by the position of the damping members in relation to the sleeve of the ejection piston or, when using cylinders as damping members, by the length of their piston rods.
  • this compression ring is placed in front of the seal receptacle. After a response and the deformation associated with it, this ring can be burnt off and a new attachment can be welded, with which the ejection piston can be put into operation again without any problems.
  • the compression ring can also be arranged after the seal receptacle; here the seal receptacle or the sleeve transmits the impact force to the compression ring, which also deforms when sufficient force is applied.
  • the sleeve of the ejection piston in the region of the pressure chamber-side guide strips and its lower half is provided with a deformable area in the form of a compression base, the segment forming this compression base preferably having channels running parallel to the axis at least over 1/3 of the length of the sleeve is provided.
  • these axially parallel grooves of the upsetting floor are preferably rounded inward and arranged at regular intervals. This results in a further safety crumple zone in this area, which responds when the ejection piston is tilted at the stop stops in the event of the destruction of particularly high energies in such a way that its front end is raised and its rear end is pressed onto the container bottom.
  • stop stops arranged in the upper vertex region are stressed with a shortened lever arm, so that the torsional forces acting on them are reduced. So that the discharge piston is finally stopped without the waste container being overstressed; however, the ejector piston is generally deformed so that major repairs may be necessary.
  • the stop stops are above the sole of the two-chamber disposal container arranged so that there are no protrusions in the sole region of the ejection of the absorbed medium.
  • the opening area of the openable cover of the two-chamber disposal container can also be limited by appropriate means. This limitation prevents the full opening of the container from being released, so that an ejection piston which has started to move, if it has overcome the brake stops and the stop stops, would ultimately be stopped by the cover which is not fully opened.
  • FIGS 1 and 2 show a side view and a top view of a disposal vehicle 1.
  • the cab 2.2 is placed on its chassis 2 with the wheels 2.1, the drive motor is generally below the cab 2.2.
  • the chassis also accommodates the actual two-chamber disposal container 3, which receives the medium to be disposed of, which is provided with an openable closure cover 3.1 for emptying its suction chamber and for cleaning it, which can be pivoted about the cover hinges 3.2 and thus the emptying opening of the two chamber -Close the disposal container 3 and release it.
  • the lid hinges 3.2 are advantageously attached to a reinforcement flange 3.4 provided at the end of the disposal container 3 and surrounding the entire container mouth, this reinforcement flange also receiving the seal which seals the disposal container 3 against its openable closure lid 3.1.
  • the pressure chamber which is closed with a solid base 3.3, is arranged facing away from the end of the two-chamber disposal container 3 on the suction chamber side.
  • the ejection piston 5 is arranged on its circumference, extending parallel to its axis Guide strips 4 held centrally in the disposal container 3; by means of these guide strips 4, the friction on the inner wall of the disposal container is decisively reduced and thus prevents it from becoming stuck.
  • the disposal container 3 contains an ejection piston 5, which is moved by means of overpressure or underpressure, in order to accelerate the emptying and to eject substances that are difficult to flow.
  • the closed part of the two-chamber disposal container 3 is pressurized via a pressure line (not shown in detail) connecting it to a pressure / suction unit, also not shown, so that a force acts on the ejection piston 5 to move it in the direction "Emptying opening" drives.
  • Normally, the collected goods in the disposal container 3 are ejected.
  • the ejection piston 5 consists essentially of the sleeve 6, the lumen of which is closed by a shut-off partition 6.1, so that the necessary pressure can build up in the closed part of the disposal container 3.
  • a manhole 6.2 (FIGS. 3, 6a) can be provided in this partition, for inspection purposes, for example.
  • FIG. 3 shows a view of the end face of the disposal vehicle 1 with the emptying opening open (the opened emptying flap 3.1 not being shown).
  • the ejection piston 5 is guided centrally in the cylindrical interior of the two-chamber disposal container 3, namely by means of guide strips 4 distributed over the circumference.

  • FIG. 4 shows a sectional illustration through the two-chamber disposal container 3 with ejection piston 5, which is in its end position “ejection”.
  • the end of the ejection piston 5 is located directly at the opening of the two-chamber disposal container 3, the closure lid 3.1 of which is open; 4a shows an enlarged detail thereof.
  • the discharge piston 5 has (almost) completely expressed the contents of the disposal container 3; a gap remaining in front of the seal 8 can be sprayed out with a water hose for cleaning without particular difficulty.
  • the ejection piston separates the pressure chamber from the suction chamber which receives the sucked-up medium;
  • the partition 6.1 is inserted into the sleeve 6 of the discharge piston 5, advantageously such that its lower edge precedes the discharge opening.
  • the curvature of the partition 6.1 shown here increases its stability against excess pressure in the closed pressure chamber of the two-chamber disposal container 3.
  • the ejection piston 5 is guided centrally by means of the guide strips 4, which slide on the inside of the jacket of the disposal container 3, these guide strips 4 are distributed symmetrically over the circumference, near the front and near the rear end of the ejection piston 5.
  • a circumferential seal 8 provides the necessary sealing on the one hand of the pressure chamber with respect to the suction chamber in order to enable the pressure necessary for the piston movement to be built up, on the other hand the seal prevents the absorbed medium from passing into the pressure chamber and pushes the collected when the ejection piston slides Medium ahead.
  • a lip facing the openable side is formed on the seal.
  • the discharge piston 5 is located in the receptacle 3 near the open discharge opening, with the brake stop 7 has stopped and pressed in the piston rod 11 of the damping cylinder 10; kinetic energy of the ejection piston is taken over by the damping cylinder and thus extracted from the ejection piston.
  • the whereabouts of this energy component depends on the type of damping cylinder 10; while a pure spring piston stores this energy in order to release it after the loss of force, a pure flow cylinder ultimately converts this energy into heat, unless a compressible gas cushion is provided to store some of the energy; it goes without saying that this stored energy can serve for the return movement of the ejection piston 5 (or at least the initiation of this return movement).
  • a spring or a gas cushion is advantageously provided so that only a part of the kinetic energy of the ejection piston is taken over.
  • the brake stop 7 is screwed in an advantageous manner in the reinforcing flange 3.4 of the two-chamber disposal container 3; it is therefore in the immediate vicinity of the open end of the two-chamber disposal container 3. With this arrangement of the brake stop 7, the application of force is optimal on the one hand and, on the other hand, the brake stop can be easily replaced in the event of an overload.
  • These stops can be designed so that the operator of the disposal vehicle or the disposal container is able to recognize overloads based on brands that remain, and can thus recognize unacceptable loads by the operating personnel when such incidents are concealed.
  • FIG. 5 shows a section corresponding to FIG. 4 through the disposal container 3 with the ejection piston 5, the ejection piston 5 being here in its rear rest position.
  • the ejection piston 5 does not require any special security per se because of the force which is limited when it is withdrawn by means of negative pressure; in cooperation with the double-acting damping cylinder 10 'shown here, however, a braked approach to this position can also be achieved if brake stops 7' close to the end closing the disposal container 3 at the pressure chamber end Floor 3.4 are provided.
  • FIG. 6 shows the ejection piston 1 with a compression ring 12 placed in front of the sleeve 6 and a further compression area in its base; for this purpose, a segment close to the ground is provided as an upset base 13 with axially parallel shafts 13.1 which, when the ejection piston 5 is tilted by the damping member moving to the brake stop 7 or the upset ring 12 to the stop stops 9 which are advantageously provided only above the sole area of the two-chamber disposal container 3 be effective.
