Definitions

  • the invention relates to a civil engineering device for inserting piling material into the ground.
  • the invention also relates to a method for operating such a civil engineering device according to the preamble of patent claim 10.
  • the hydraulic group usually consists of a hydraulic pump that is driven by an internal combustion engine, in particular a supercharged diesel engine, a working device with a hydraulic drive, in particular a hydraulic motor, and a control or regulation unit.
  • the hydraulic group is operated with a fluid in a hydraulic circuit. The product of the pressure and volume flow of the fluid gives the hydraulic power.
  • the internal combustion engine driving the hydraulic pump is dimensioned correspondingly large.
  • vibration rams or vibrators are used as working devices to introduce objects such as steel profiles into the ground or to pull them out of the ground or also to compact soil material.
  • the soil is excited by vibration and thus reaches a "pseudo-liquid" state.
  • the pile can then be pushed into the subsoil by static load.
  • Vibratory hammers regularly have linearly acting vibration exciters, the centrifugal force of which is generated by rotating imbalances.
  • the course of the speed of the linear vibration exciter corresponds to a periodically recurring function, for example a sine function.
  • the vibration exciters are operated with hydraulic rotary drives which set the shafts on which the unbalances are arranged in rotation.
  • vibration rams To pick up an object to be introduced into the ground, vibration rams have clamping pliers through which the Vibrations of the vibrator as well as the static load are transferred to the recorded object.
  • hydraulic presses are used as tools.
  • Such hydraulic presses have an arrangement of clamping tongs, which are each connected to a hydraulic cylinder and each serve to accommodate an object, for example a sheet pile. By operating the hydraulic cylinder, the objects picked up by the clamps can be pressed into the ground or pulled out of it.
  • the clamping tongs which are arranged for receiving the objects to be brought into the ground or pulled out of the ground, can be actuated via one or more hydraulic clamping cylinders, which are also operated via the fluid of the hydraulic group.
  • the clamping pliers are of great safety importance. In order to ensure the secure fixation of an object to be introduced into the ground on the working device, a continuous pressure supply of the at least one clamping cylinder of the clamping pliers must be guaranteed to ensure the required clamping force. Therefore, in practice, during breaks in the civil engineering work, the internal combustion engine continues to operate in order to maintain the comparatively low pressure required for the clamping force of the clamp pliers, which results in a considerable consumption of diesel fuel.
  • the DE 10 2013 103 715 A1 proposed to recognize operational pauses on the basis of operating parameters of the working device and to switch off automatically during an operational pause of the internal combustion engine.
  • the latter should be monitored and the internal combustion engine should be switched on automatically when the pressure drops below a predetermined value.
  • the diesel engine should only be switched off when the clamping pliers are opened, i.e. without function or the function of the clamping pliers via the control of the Clamping pressure is ensured. If the clamping pressure falls due to a leak in the clamping cylinder, the diesel engine is started and oil is replenished into the clamping cylinder.
  • the disadvantage of this proposed solution is that starting and subsequent operation of the internal combustion engine to restore the pressure required for the clamping force requires a disproportionately large amount of energy or diesel fuel.
  • a diesel engine with several hundred kilowatts of clutch power is started. More energy is required to start the diesel engine than to replenish the hydraulic oil.
  • the diesel engine has an idling consumption that is in a very unfavorable relationship to the power required to replenish hydraulic oil.
  • the diesel engine is loaded by the drag power of the large hydraulic pumps connected to it, which are dimensioned to drive the working device and which regularly rotate with the diesel engine.
  • the invention aims to provide a remedy here.
  • the invention is based on the object of providing a civil engineering device in which the energy consumption or diesel consumption of the civil engineering device is reduced, especially during breaks in operation. According to the invention, this object is achieved by a civil engineering device having the features of the characterizing part of claim 1.
  • the invention provides a civil engineering device in which the energy consumption or diesel consumption of the civil engineering device is reduced, particularly during breaks in operation.
  • Another hydraulic pump is arranged to build up the clamping pressure of the clamping cylinder of the clamping device, which is operated by an electric motor, enables pressure drops to be compensated for, for example due to a leak in the clamping cylinder, without starting the internal combustion engine.
  • the electric motor for operating the further hydraulic pump can be fed, for example, via the accumulator of the internal combustion engine, which is regularly available for the required electric starter of the internal combustion engine.
  • the hydraulic pump driven by the electric motor for building up the clamping pressure is a radial piston pump. This enables the high pressure required for the clamping cylinder to be provided.
  • the hydraulic pump driven by the electric motor to build up the clamping pressure is connected in parallel to a hydraulic pump driven by the internal combustion engine to build up the clamping pressure.
  • This achieves a redundant arrangement in which the clamping cylinder can be supplied exclusively by the hydraulic pump operated by the electric motor, that is to say also when the working device is in operation.
  • the hydraulic pump driven by the electric motor ensures that the required clamping pressure is maintained even if the internal combustion engine or the hydraulic pump driven by it fails.
  • a pressure booster for increasing the hydraulic pressure provided by this is arranged behind the electrically driven hydraulic pump in the direction of flow of the hydraulic fluid. This enables the use of a smaller hydraulic pump.
  • the electrically driven hydraulic pump is controlled in such a way that it - alone or in conjunction with a pressure intensifier - provides a higher pressure than the hydraulic pump operated by the internal combustion engine to build up the clamping pressure, the maximum clamping pressure preferably only being provided by the electrically driven Hydraulic pump is provided. This enables the unit made up of the electric motor and hydraulic pump to be smaller for building up the clamping pressure.
  • the internal combustion engine and the work device are connected to a controller which is set up to query at least one operating state value when the work device is deactivated in order to control the internal combustion engine to stop automatically or to recommend stopping the internal combustion engine via a signal, in particular via a display, to the operator if the at least one operating state corresponds to an assigned default value.
  • a temperature sensor for measuring the hydraulic fluid temperature and / or a temperature sensor for measuring the internal combustion engine oil temperature is advantageously arranged, which temperature sensor is connected to the controller, the controller being set up in such a way that the internal combustion engine is stopped or a recommendation is made when the temperature falls below a limit temperature assigned to a temperature sensor does not take place to stop the internal combustion engine.
  • a pressure sensor is arranged for continuous measurement of the clamping pressure of the clamping device, which is connected to a control and regulating device which is set up in such a way that when the clamping pressure drops below a predetermined minimum pressure value, a pressure increase is caused by the pump operated by the electric motor takes place on a predetermined target printing unit.
  • the electric motor is fed via an accumulator which is connected to a charging device operated by the internal combustion engine, with a sensor for continuous measurement of the state of charge of the accumulator being arranged which is connected to a control device for controlling the internal combustion engine, which is set up in this way is that the internal combustion engine starts automatically when the battery pack falls below a specified minimum charge level. This ensures reliable operation of the electric motor for driving the hydraulic pump operated by it.
  • the invention is also based on the object of creating a method for operating such a civil engineering device which enables the required energy or diesel consumption of the carrier device to be reduced. According to the invention, this object is achieved by the features of the characterizing part of patent claim 10. Because the clamping pressure of the clamping cylinder of the clamping device is maintained by a hydraulic pump operated by an electric motor at least when the internal combustion engine is stopped, the internal combustion engine does not need to be started in the event of a pressure drop in the clamping cylinder of the clamping device. It is noteworthy at this point that the energy requirement for replenishing the tensioning cylinder is lower by around two powers of ten compared to the energy required to start the internal combustion engine.
  • the opening state of the clamping device is queried as the operating state value, with the internal combustion engine only being stopped when the collet is closed when the pump operated by the electric motor is activated. This effectively counteracts unintentional opening of the collet.
  • the electric motor is operated via an accumulator and the charge status of the accumulator is queried as a further operating state value, with the internal combustion engine only being stopped with the collet closed if the charge status of the accumulator is above a predetermined minimum charge level. This ensures reliable operation of the electric motor when the internal combustion engine is stopped.
  • a clamping pressure of the clamping device is continuously queried as the operating state, the internal combustion engine being stopped if, with the clamping device closed, the clamping pressure is greater than a predetermined minimum pressure.
  • a hydraulic oil temperature and / or an engine oil temperature of the internal combustion engine and / or an engine coolant temperature of the internal combustion engine is preferably queried as an additional operating state value, the internal combustion engine not being switched off if a queried temperature is below an assigned minimum temperature.
  • the high pressure required to operate the clamping cylinder is maintained by the hydraulic pump, which is operated by an electric motor, regardless of the operating state of the internal combustion engine. This avoids starting the internal combustion engine to produce the pressure required to operate the clamping cylinder.
  • the civil engineering device selected as an exemplary embodiment is designed as a vibration pile driver 1, which is connected to a hydraulic unit 2 in a hydraulic circuit 5.
  • the vibration pile driver 1 comprises, in a known manner, a vibrator transmission 11 with shafts 12 arranged parallel to one another, which are provided with unbalances 13 and which can be driven by a hydraulic motor 14.
  • a vibration transmission is for example in EP 1 967 292 A2 described.
  • a clamping device 15 designed in the form of clamping pliers is arranged, which in known Way has a clamping cylinder 16 for clamping the pile.
  • the hydraulic unit 1 comprises an internal combustion engine, in the present case a charged diesel engine 21, which drives a hydraulic pump 22.
  • the hydraulic pump 22 is connected via hydraulic lines 51 of the hydraulic circuit 5 to the hydraulic motor 14 of the vibrator transmission 11 of the vibration pile driver 1.
  • a second hydraulic unit 4 which comprises an electric motor 41 which drives a second hydraulic pump 42, is also arranged on the vibration pile driver 1.
  • the electric motor 41 is connected to an accumulator 43 for the voltage supply.
  • the hydraulic pump 42 operated by the electric motor 41 is connected to the clamping cylinder 16 of the clamping device 15 via hydraulic lines 52.
