Definitions
- the invention relates to a device and a method for compensating for at least vertical changes in position in response to fluctuations in the ground.
- the invention relates to machines or devices or applications in connection with material flow, logistics, conveyor technology.
- the invention relates to a device and a method according to the preamble of the respective independent or co-ordinate claim.
- the damage becomes particularly costly when very large, heavy devices such as excavators, cranes, conveyor systems, rail vehicles or crawler vehicles are affected.
- all those systems can be named that are used in open-cast mining for the transport, relocation, dismantling or filling of earth or stones.
- chassis components can be damaged or the systems fall over completely; disadvantageously, the systems can then possibly no longer be erected or repaired with the locally available devices.
- the earthquakes are so strong that the devices are regularly lifted off track or even overturned (partial or complete lifting), with correspondingly serious consequences.
- the actual specifications e.g. dismantling of material
- Damage to people, material and nature can often not be avoided.
- the cost of repairs or maintenance threatens to become immeasurably high. In some cases, a repair is no longer even financially or technically feasible.
- the ISO 11031 standard in particular version 2016-09-15, also describes a context or guide for a technical design of systems with regard to earthquake risks, whereby essentially three different approaches for the design are presented: "modified seismic coefficient method” ; “Maximum response spectrum method”; “Time history response method”.
- WO 2012/117573 A1 describes a system for releasing a translational relative movement of a rail vehicle along rails in response to a measured threshold value for an earthquake. From GB 2326629 A a crane with an extendable tree with a balancing mass and isolation against seismic loads is known.
- a stabilization platform with electrical actuators and a gyroscope sensor is known from WO 2016/068826 A1.
- the object of the invention is to provide a device and a method with the features described above, with which the safety of process engineering systems or machines, in particular conveyor systems, can be improved with regard to unexpected changes in position due to external effects such as earthquakes.
- this object is achieved in particular by a mobile machine device with a material flow and / or logistics function, in particular a mobile conveyor technology device, set up to compensate for at least vertical changes in position (height positions) in response to fluctuations, in particular vertical fluctuations in the subsoil, in particular in response to seismatically caused ground fluctuations, especially in response to earthquakes, in particular in the case of a (not advanced) mobile machine device arranged stationary in a horizontal plane, with: a substructure with a large number of
- Ground contact units in particular comprising or in the form of
- Wheel units set up to support the entire machine device on the ground, in particular set up for mounting the machine device on rails or on another roadway; and with a superstructure set up to provide the material flow and / or logistics function, for example at least comprising one component from the group: crane, boom, ejector, conveyor belt, bunker, bridge; wherein at least one force application unit is coupled to at least one of the ground contact units, in particular to at least two ground contact units, the absolute vertical force (vertical preload) provided by the at least one force application unit or by all force application units (and acting on the machine device) in the direction of action on the ground contact units is oriented in the downward direction and is less than the absolute weight of the machine device (with reference to the usual acceleration due to gravity), the at least one force application unit being integrated in the substructure, in particular in the respective ground contact unit, that the machine device is at rest when the device is at rest Stop can be stored, that is to say non-resiliently without a resilient effect of the force application units, that is to say with a rigid coupling
- a support “on stop” is to be understood as a support in which a spring action or a damper effect does not influence the support or at least the relative position of the mounted components.
- the vertical force or preload is therefore smaller than the weight force, so that even a continuously provided preload cannot lift the machine device under normal acceleration due to gravity or cannot float.
- a “stop” bearing is to be understood in particular as a non-elastic, inelastic bearing (without elastic resilience) with contact between at least two essentially rigid components without an integrated spring or damping function.
- the storage on the stop is to be understood as at least essentially unsprung storage.
- the storage “on stop” can also be limited or predefined vertically upwards by a predefined stop (machine element) in a predefined relative position.
- the measures according to the invention can in particular also prevent a structurally highly stressful impact-like impact after the device has been lifted off.
- the preload is so low that the device is not floatingly mounted with spring deflection in both vertical directions, but the preload is preferably so great that a dampening or interception of a vertical acceleration on impact can be felt.
- the probability (or the risk) of a loss of ground contact can also be significantly reduced, even without the use of counterweights, in particular in the case of both vertical and horizontal accelerations.
- the device can be designed to be slimmer from a structural point of view or else be loaded with a relatively larger amount of material for the conveying function.
- the force application units do not have to fulfill any active vibration-related function, in particular no resilient or damping function of chassis with regard to dynamic locomotion or with regard to any continuously applied vibrations or oscillations. Rather, the force application units are set up to initiate or bring about a relative change in height position of the ground contact units as a function of vertical force threshold values. In other words: the Force application units are set up for an adjustment movement downwards vertically in response to a momentary reduction in the momentarily acting gravitational force, in particular if this is smaller than the absolute mass of the device at normal acceleration due to gravity.
- the absolute force is to be understood as the sum of the forces acting on the device as intended or for a specific purpose, in particular the sum of all acting force application units, in particular in relation to a predefined direction, in particular at least in an exactly vertical downward direction.
- the suspension of rail vehicles is a standard measure in the prior art.
- Leaf springs, air springs, and spiral springs have traditionally been used for such suspensions since time immemorial.
- typical rail vehicles are, in particular, rail vehicles.
- the devices In the field of conveyor technology (handling technology), especially in cranes and large machines mounted on rails or caterpillars, the devices are in many cases movable or mobile, but essentially stationary for most of their use. This is required due to the system alone due to the use of conveyor belts or similar material flow components.
- a suspension / damping or a floating mounting in the tolerance range of the spring force (vertical spring force greater than or equal to the total mass; spring travel both upwards and downwards) comparable to dynamically propelled vehicles is therefore usually not provided.
- the present invention builds on, in particular based on the knowledge that in the case of a pretensioned mounting, there is a stop a spring effect is only exerted when the effective vertical force is less than the total mass, i.e. when the vertical spring force is less than the total mass.
- the adjusting movement is only activated when the momentarily acting gravitational force or inertial forces fall below a vertical force that acts as standard at the shear point (corresponding to an activation of the adjusting movement caused by external (gravitational) effects).
- the measures according to the invention not only improve ground contact, but can also ensure an advantageous catching function, in particular a damping function, when a device that is momentarily lifted vertically upwards hits the ground again.
- the absolute pre-tensioning force is set smaller than the total mass of the device, it can be ensured that even in the event of a long-lasting earthquake, there is no need to worry about the device swinging up or the risk of resonance.
- a downward movement caused by an earthquake back into the vertical zero position (support) can be intercepted in a very reliable manner by means of the force application units, in particular in a purely passive manner.
- buffers or dampers can be integrated into the force application units, in particular rubber buffers and / or fluid dampers.
- a bearing that is pretensioned against gravity to the stop has the particular advantage that there is no risk of a suspension system breaking through or irreversibly destroying it in the case of a floating bearing, even if high, unforeseen vertical accelerations occur due to earthquakes.
- the force application unit acts between the ground contact units and the substructure in such a way that the ground contact units exit the substructure in the event of vertical changes be pushed out. In this way, an efficient downward adjustment movement can be ensured, in particular largely independent of the mass or the structural design of the superstructure.
- the direction of gravity is also to be understood here as the vertical direction in the narrower sense.
- the at least one ground contact unit is supported elastically pretensioned in the vertical effective direction.
- the at least one force application unit can be a force application unit that acts at least approximately in the direction of gravity (force acting direction downwards, in particular vertically downwards). In this way, great operational reliability can also be provided; In particular, active regulation can be dispensed with.
- the (respective) force application unit is in particular set up and arranged for unidirectional force application of the at least one ground contact unit downwards in the direction of gravity, in particular all of the ground contact units.
- the (respective) force application unit is set up to provide vertical accelerations at the ground contact units in the direction of gravity greater than the acceleration due to gravity, in particular greater than 10 m / s 2 or greater than 12 m / s 2 . In this way, it is also possible to compensate for comparatively large instantaneous variations in the acceleration due to gravity actually acting.
- the amount of an acceleration of the ground contact units to be implemented can also be designed or predefined locally (on individual ground contact units) between the ground and the machine device as a function of the magnitude of the maximum expected relative accelerations as a result of earthquakes in the vertical direction.
- the inertial forces or inertial effects acting on the at least one ground contact unit are smaller by a factor of at least two or three digits than those on the entire machine device attacking inertial forces or Inertia effects.
- this favors a short reaction time for a downward adjusting movement caused by the force application units, so that a position change reaction of the entire machine in the direction of gravity can be preceded by inertia.
- inertia effect can refer to both inertia forces and moments of inertia.
- the present invention relates primarily to translatory (vertical) movements of the ground contact units, so that moments of inertia can also be at least partially neglected or assumed to be zero, for example.
- An adjusting function in the downward direction provided by prestressing can be provided by maximum prestressing in the standard stop position with normal acceleration due to gravity, in particular by spring prestressing. Since the preload is already maximally high in the zero position, a particularly good reactivity of the adjusting movement can also be ensured. With an elastically pretensioned spring, this setting function can also be continuously maintained or ensured in a particularly operationally reliable manner in a passive manner.
- the ground contact units are mounted so that they can be vertically displaced relative to the superstructure by means of a plurality of force application units such that a relative change in position starting from a vertical zero position is released exclusively downwards to increase the vertical distance between the subsurface and the superstructure.
- the ground contact units comprise wheel units which can be displaced vertically downwards from a vertical zero position (corresponding to the support position) in response to a reduction in the effective weight force currently acting on the wheel units.
- wheels including the components permanently connected to them, can be in vertical direction are relocated downwards in the substructure, in particular fully automatically as a function of vertical force threshold values, in particular passively solely on the basis of instantaneous, externally justified vertical force differences or vertical force variations.
- the elastic units are preferably pre-stressed in a predefinable manner.
- the preload in particular spring force, is preferably continuously applied in the vertical direction at the bottom. This enables an arrangement without active regulation, whereby a very high level of system security can be ensured.
- the ground contact units are preferably supported elastically pretensioned in the vertical effective direction exclusively by the weight of the entire device itself.
- the force application units can be locked in a predefined vertical relative position in the ground contact units or can be fixed in a predefined relative position and switched ineffectively by means of a plurality of locking elements. This also enables the vertical positioning function to be switched on and off as an option.
- the absolute vertical force provided by a plurality of force application units is less than a factor of 2 than the absolute weight force of the mobile machine device, in particular less than a factor of 3 or in the range from a factor of 3 to 10 or less than a factor of 10 or in the range from a factor of 11 to 25 or a factor of 30 to 100.
- the measure according to the invention can also be implemented in a comparatively lean manner with little expenditure in terms of costs or materials.
- the (respective) force application unit is set up to provide vertical adjustment paths (or spring paths) of at least 5 cm or at least 10 cm or at least 15 cm or at least 20 cm.
- vertical adjustment paths or spring paths
- the spring travel can in principle be set to any size.
- the required spring deflection also depends on the intensity / level of the expected earthquake acceleration as well as the temporal progression or the duration of the ground tremors, and should therefore preferably be specified individually for a particular application or for a particular earthquake area.
- the at least one force application unit has at least one spring, in particular at least one spring that is maximally pretensioned to the stop when the machine device is at rest, in particular a spring with a maximally soft spring constant, in particular a spring with maximally rapid response, in particular a spring with sufficiently great rigidity.
- the effect of the force application unit can be further optimized with regard to the desired safety function in the event of unforeseen variations in the effective acceleration due to gravity or the instantaneous vertical forces.
- the respective spring can in particular be designed as a compression spring. Alternatively or additionally, tension springs can also be provided.
- the respective spring can act, for example, on a single wheel of the ground contact units, and / or, in particular in the case of comparatively low accelerations to be expected, also on an entire swing arm comprising several wheels.
- An articulated swing arm can be designed as a five-wheel swing arm, for example.
- the at least one force application unit is arranged on the respective ground contact unit or is in operative connection therewith in such a way that the mass that is prestressed and to be moved by the force application unit in the direction of gravity is minimally large, in particular only with regard to wheels or similar ground contact machine elements.
- the operational reliability can be further improved, in particular thanks to faster response times, in particular thanks to the minimized inertia of the components to be placed (to be moved downwards).
- the ground contact machine elements can also be designed as elements with a propulsion function, for example drive wheels that transmit drive torques.
- the force application units can be designed to be comparatively slim or can be dimensioned to be comparatively small and inexpensive.
- the at least one force application unit is arranged as far as possible at the bottom of the respective ground contact unit in such a way that the components preloaded by the force application unit in the direction of gravity and to be moved are minimized in number and mass, in particular are limited to wheels or, optionally, also wheel swing of the respective ground contact unit .

- the mobile machine device has a total mass greater than 10, 100 or 1000 tons. In comparison to this, the masses to be moved by the force application units are comparatively small, in particular a factor of less than 100 or 1000 or an even greater factor.
- the mobile machine device is mobile in at least one spatial direction, preferably in at least two spatial directions, in particular comprising at least one propulsion unit arranged in the substructure in operative connection with the ground contact units. Mobility can be ensured, for example, by propulsion, which enables slow shifting along a predefined movement path, e.g. on rails.
- the mobile machine device is a vehicle, in particular a rail vehicle or a tracked vehicle.

- On the wheel unit (s) 15 acts in the center of gravity by a (instantaneous) weight Fg.
- a spring force F1 and a force F2 exerted in the stop position act in the same direction as the weight Fg.
- the sum of all these forces corresponds to the reaction force F3 on the ground, which is caused by all wheel units are exercised on the ground.
- This balance of forces can be used as the basis for determining the appropriate spring constants and spring stiffnesses, as explained below.
- a required or appropriate preload can be determined specifically by a spring force or spring stiffness or can be predefined for a structural design.
- the preload can also be provided by means of alternative components that have the same effect.
- M mass of the entire machine device m mass of a respective ground contact unit g gravitational acceleration x vertical center of gravity coordinate (height position) of a ground contact unit in the inertial system
- the parameter x (x derived twice from time) describes both the center of gravity acceleration of the respective ground contact unit and the ground acceleration below this ground contact unit.
- a spring force F1 acts between each ground contact unit and the machine device according to the following equation:
- a pulse balance can be set up for a single ground contact unit (with Mg corresponding to the weight Fg), whereby the relationships can also be transferred to real systems based on several ground contact units:
- x ' n0 rm denotes the lowest (lowest) value (threshold value, limit value) for the ground acceleration permitted for normal operation (x " n0 rm).
- the relevant ground acceleration for lift-off is negative, i.e. x" n0 rm ⁇ 0.
- the condition described above is for the spring stiffness c is fulfilled for any (positive) values of the spring stiffness. Under these conditions, the contact between the ground contact unit and the ground would remain even without the use of a pre-stressed actuating function or elastic support if an exclusively vertical movement (but no tilting due to horizontal acceleration components) is considered. If, however, it is assumed, for example, that the vertical acceleration of the ground relative to the ground contact unit reaches -1.1g, i.e. that the acceleration due to gravity is exceeded by 10%, then the spring stiffness c> mg / 10 (ly) where here for y the maximum value to be expected as a result of ground vibrations must be used
- Machine device by defining the characteristic of the adjusting movement or the characteristic of the spring preload.
- the person skilled in the art can undertake a device-related optimization of the actuating function, in particular with regard to minimized reaction times.
- M mass of the entire machine device m mass of a respective ground contact unit g gravitational acceleration x vertical center of gravity coordinate (height position) of a ground contact unit in the inertial system x16 height range of the wheel rim
