Definitions

  • the invention relates to a working device with hydraulic drive for civil engineering work, in particular a piling or drilling apparatus according to the preamble of claim 1.
  • the invention further relates to a method for operating a working device with hydraulic drive for civil engineering work, in particular a piling or drilling rig according to the preamble of Patent claim 4.
  • the hydraulic group usually consists of a hydraulic pump, preferably with variable displacement (variable displacement), by a drive motor, for.
  • a working device with hydraulic drive z. B. a hydraulic motor and a control unit.
  • the hydraulic group is operated with a fluid in a hydraulic circuit. The product of pressure and volume flow of the fluid gives the hydraulic power.
  • Vibration rams are used, for example, to bring objects such as profiles in the ground or to pull out of the ground or to compact soil material.
  • the soil is stimulated by vibration and thus reaches a "pseudo-liquid" state.
  • By static load the pile can then be pressed into the ground.
  • Vibration rams regularly have linearly acting vibration exciters whose centrifugal force is generated by rotating imbalances.
  • the course of the velocity of the linear vibration exciter corresponds to a periodically recurring function, for example a sine function.
  • the vibration exciters are operated with hydraulic rotary actuators, which set the waves on which the imbalances are arranged in rotation.
  • the required drive power can differ considerably during operation. So z. B. different soil conditions or different Rammgut different drive power. At idle, however, the required drive power is very low. Thus, situations occur regularly in which the maximum power offered by the hydraulic circuit is not required, or can not be implemented. In conventional vibration exciters with hydraulic motors, which do not have a variable displacement (constant speed motors), the working pressure is reduced at a constant volumetric flow, while the volumetric flow-dependent power losses in the hydraulic circuit remain constant.
  • variable displacement variable displacement
  • drills are used, inter alia, for the production of pile foundations, z. B. bored piles and concrete piles used to increase the sustainability of the ground or for soil replacement measures.
  • the drilling drives connected to the drill are generally hydraulic rotary drives to which a drill string or drilling tools is or are attached.
  • Object of the present invention is to provide a working device with hydraulic drive for civil engineering work, in which the efficiency is increased. According to the invention, this object is achieved by a working device having the features of patent claim 1.
  • the torque required for drilling increases with increasing depth.
  • the implement is operated at maximum speed, but works due to the low load at very low pressure.
  • the resulting volume flow and pressure power is low, the power loss, which results independently of the pressure from the flow, already reaches its maximum value.
  • the power loss remains approximately the same.
  • the speed of the implement decreases and the pressure continues to rise. If the speed of the implement continues to decrease after reaching the maximum allowable pressure, the pressure will remain constant, reducing the volume flow offered in the hydraulic circuit yourself. This means that the power offered in the hydraulic circuit can not be called up any more than with maximum flow and low pressure.
  • a lower speed can be used to achieve a higher speed and faster drilling at low load, or to reduce the power dissipation resulting from flow resistances by simultaneously reducing the flow rate.
  • the characteristic curve of the hydraulic circuit usually the achievable pressure is shown as a function of the volume flow
  • the volume flow of the hydraulic circuit can be adjusted by appropriate settings of the pump, eg. be specified by changing the speed of the drive motor and / or changing the displacement of the pump.
  • the displacement of the variable displacement motor is adjusted depending on the pressure, so that the implement is always operated in the range of maximum power. At high load, the speed of the implement will be lower than at low load. If the power is not required, the displacement of the variable displacement motor and the volume flow should be reduced at the same time, so that the optimum pressure is maintained and the losses in the hydraulic circuit are reduced to a minimum.
  • the displacement of the variable displacement motor as well as the volume flow must be regulated as a function of the pressure.
  • the present invention makes it possible, on the one hand, the offered On the other hand, the power loss can be reduced with lower power requirements.
  • the "displacement volume" of a hydraulic motor or a hydraulic pump is understood to mean the amount of hydraulic fluid which is enforced during rotation. While in conventional hydraulic motors with fixed displacement a reduction of the speed is only possible through a reduction in the flow rate, which simultaneously reduces the performance of the engine can be reduced with a variable displacement hydraulic motor at a constant flow rate by changing the absorption volume, the speed at the same time The torque of the engine is increased and the power remains constant.
  • the power can be adjusted via the flow rate provided by the hydraulic pump at a constant speed of the hydraulic motor.
  • the means for changing the volume flow are formed by a drive motor through which the pump is operated, wherein to reduce the volume flow, the speed of the drive motor can be reduced via the control unit. Reducing engine speed minimizes fuel consumption and reduces noise emissions from the engine.
  • the hydraulic pump has a variable displacement volume, whereby the means for changing the volume flow are formed, wherein the displacement volume of the hydraulic pump for reducing the volume flow via the control unit is reducible.
  • the present invention is further based on the object, a method for operating a working device with hydraulic drive for civil engineering work, in particular a pile or drilling rig, comprising at least one hydraulic motor with variable displacement, which is operated via a fluid of a hydraulic circuit, which is powered by a pump is to provide, which allows a higher efficiency of the implement.
  • this object is achieved in that at a pressure drop in the hydraulic circuit, the displacement of the hydraulic motor and the fluid volume flow is reduced.
  • a method for operating a working device with hydraulic drive which allows an increase in power transmission, or reduces the losses of the hydraulic group to a minimum.
  • the hydraulic pump is driven by a drive motor, whereby the reduction of the volume flow takes place by reducing the speed of the motor.
  • a hydraulic pump with variable displacement is used, wherein the reduction of the volume flow is effected by reducing the absorption volume of the pump.
  • the vibration generator 1 selected as an exemplary embodiment of a vibration ram (not shown) consists essentially of a housing 10 in which working shafts 11 provided with toothed wheels 12 are rotatably mounted.
  • the gears 12 are each provided with imbalance masses 13, wherein the gears 12 of both working shafts 11 via gears 15 with the rotor shaft 16 of a pivot motor 14 are engaged.
  • the provided with imbalance masses 13 gears 12 are adjustable relative to each other via the pivot motor 14 in its rotational position, whereby the resulting imbalance or the resulting static torque is adjustable.
  • the drive shafts 11 are each connected to a hydraulic motor 2, via which they are driven.
  • Vibratorgetriebe are the expert, for example from the DE 20 2007 005 283 U1 known.
  • FIG. 2 the hydraulic circuit for a hydraulic motor 2 of the vibrator 1 is created in principle.
  • the hydraulic motor 2 has a variable displacement and is fed via a variable displacement pump 3, which is driven by a drive motor 4.
  • the hydraulic motor 2 upstream of a pressure sensor 5 is arranged, which is connected to a control and regulating device 6.
  • the control and regulating device 6 is set up in such a way that a reduction in the absorption volume of the hydraulic motor 2 as well as a reduction in the volume flow is effected in the event of a pressure drop in the hydraulic circuit.
  • the control and regulating device 6 is connected in the embodiment both with the variable displacement pump 3, as well as with the drive motor 4.
  • control and regulating device 6 is adjustable, to what extent a required reduction in the volume flow by reducing the absorption volume of the variable displacement 3 or by reducing the Speed of the drive motor 4 is effected.
  • the reduction of the volume flow is only possible by reducing the absorption volume of the variable displacement pump 3 or only by reducing the speed of the drive motor 4.
  • the pressure of the hydraulic circuit upstream of the hydraulic motor 2 is detected continuously via the pressure sensor 5 and reported to the control and regulating device 6. If a pressure drop is detected, which may be caused, for example, by a change in the soil condition and the associated reduced power requirement, or by a rest phase during operation, the speed of the drive motor 4 is reduced and / or the displacement of the variable displacement 3 is reduced. At the same time, the displacement of the hydraulic motor 2 is reduced via the control and regulating device 6 such that the rotational speed of the hydraulic motor 2 remains constant.
