Definitions

  • the invention relates to a soil compacting machine according to the preamble of claim 1 and a method for its operation according to claim 18.
  • soil compaction equipment with a vibratory plate such as a vibratory plate
  • a vibratory plate has an internal combustion engine. This is used to drive two identical imbalance shafts arranged in parallel and rigidly coupled in opposite directions via a gear.
  • the opposite rotation of the unbalanced shafts which are operated at the same number of revolutions, causes the centrifugal forces generated by the unbalanced masses to reinforce or compensate each other, depending on the phase angle of the unbalanced mass.
  • a resultant force vector that can be used for locomotion and/or compaction arises through a suitable setting of the respective phase position of the imbalances relative to one another.
  • a vibrating plate usually has hydraulics for adjusting the phase position of the shafts that are mechanically coupled to one another. Without further measures, the drive direction is limited to driving forwards and backwards.
  • a plate compressor which has a large number of excitation units for forming a force vector, the individual excitation units working, for example, according to the principle described above.
  • the large number of excitation units allows, among other things, the formation of force vectors that act in the lateral direction.
  • the large number of excitation units increases the mechanical complexity considerably.
  • the disadvantage of the prior art is that even with a simple design, there is wear and tear, e.g. of bearings, electrical connectors, belts, drive parts and dampers, and consumption of consumables such as engine oil, hydraulic oil and fuel, service and repair work is required. Service work is often not carried out at all and if it is, then only irregularly. If the machine breaks down, repairs by specialist personnel are usually necessary. With the increase in the complexity of the soil compaction machine occurring in the state of the art, the risk of failure of individual components as well as the necessary qualification of the service personnel increases on the one hand. The error is often difficult to identify.
  • the object of the invention is to enable permanent, reliable operation of soil compacting machines without lengthy downtimes occurring on construction sites. Above all, unqualified service personnel, for example those who hire such soil compaction machines, should be supported as conveniently as possible in operation, and above all construction companies and rental companies should be relieved of maintenance and remote service.
  • the invention relates to a soil compacting machine, hand-operated and/or remote-controlled, e.g. a vibrating plate or a vibrating tamper, with a compacting plate and a compacting drive which drives the compacting plate, and with an operating state determination device for determining one or more operating states, in particular from the group of engine data, engine temperature, engine oil pressure, Engine oil level, fuel level, fuel consumption, particle filter condition, particle filter regeneration, anti-vibration metal buffer wear, maintenance interval, operating hours, drive status data, battery condition, battery charge status, spring-damper systems, fluid levels, V-belt wear, anti-vibration metal buffer wear, fuel consumption, exciter bearing overheating, air filter contamination, incorrect or third-party air filter used, whereabouts (e.g.
  • the soil compaction machine has a screen
  • the operating state determination device has an error determination unit for determining faulty operating states among the specific operating states, the error determination unit having a memory with an error list of potential faulty operating states that are linked to digitized operating instructions.
  • the error determination unit is preferably designed to output an error message on a determined, error-prone operating state based on the error list via the screen, including an output of the linked digitized operating instructions, this in particular graphically and/or in text form.
  • Operating instructions should be understood to mean, for example, targeted troubleshooting and troubleshooting, training material (including films), installation instructions for accessories, maintenance instructions and assembly instructions.
  • the screen is preferably a high-resolution color display. Correspondingly, a large number of possibilities are opened up with regard to the output of the operating instructions, which ultimately make operation easier.
  • Precise assistance is particularly successful in an optional embodiment according to which the digitized operating instructions stored on the memory contain at least some visual instructions, the error determination unit being designed in particular to output the digitized operating instructions with at least one visual instruction.
  • visual instructions also overcome language barriers that are often encountered on construction sites. The handling of the machines is improved, the service life of the machine is increased and damage to the machine due to incorrect operation can be prevented.
  • the error determination unit can be designed to output the digitized operating instructions by means of at least two consecutive visual instructions, either graphically consecutively or sequentially with a time delay.
  • the operator is guided step by step through troubleshooting.
  • the visual instructions include photographs, animations, abstractions or pictograms of the soil compaction machine or parts thereof. This ensures that the operator can understand and carry out the specific instructions as quickly as possible.
  • an optional development also contributes to this, according to which the visual instructions for troubleshooting at least partially visually represent and/or identify components of the soil compaction machine that are to be actuated.
  • a variant is also available in which the digitized operating instructions stored on the memory have steps to be processed, for example loosening the screw, opening the flap, replacing the component, closing the flap, tightening the screw. In this way, too, an operator is guided in a targeted and step-by-step manner through troubleshooting.
  • the soil compacting machine prefferably has at least one monitoring sensor, and for the error determination unit to be designed to use the monitoring sensor or sensors to determine whether an issued digitized operating instruction is being followed.
  • a door contact could be used to monitor a service flap to check whether the user opens or closes the service flap in accordance with the operating instructions.
  • the soil compacting machine preferably has an operating device which is designed to call up the operating states via the screen and/or to confirm or acknowledge operating instructions displayed on the screen.
  • the operator can sometimes also have the option of correcting the error immediately or with a delay. For example, maintenance could be carried out immediately, the error could possibly be compensated for or accepted by the machine, and maintenance of the machine can then take place at a later point in time.
  • the operating device can be a separate button or switch, a control panel with several buttons and/or switches and particularly preferably a touch screen (touch-sensitive screen). The latter preferably as part of the screen.
  • a possible supplement can be that the digitized operating instructions stored on the memory, in particular the visual instructions, include spare parts information, component specifications and/or identification or component numbers. Troubleshooting is not always possible without spare parts. In such cases, the correct replacement part can now be procured quickly and reliably. At the same time, customer loyalty in the spare parts sector is increased.
  • the digitized operating instructions stored on the memory include a machine-readable code, preferably a QR code, with the code being linked to machine documentation and/or a service page stored externally from the soil compaction machine .
  • a QR code can quickly direct an operator to a help page via their mobile phone. This can be a hotline, a help chat, a spare parts warehouse or dealer and much more.
  • the QR code can also be used simply to view the operating instructions off the screen of the soil compaction machine and to share them, e.g. with a rental company, who then organizes the necessary spare part, for example.

This allows measurement protocols to be created that document the work carried out.
  • the compaction measurements can be used to draw conclusions about the functional capability, from which a faulty operating state can in turn be recognized by the fault determination unit.
  • the soil compacting machine can optionally have a control device with which the compaction drive is controlled and/or regulated as a function of the operating states.
  • faulty operating states in particular can be prevented in advance using control technology or corrected using control technology immediately after they have been determined.
  • a falling oil pressure could be corrected by increasing the power of the oil pressure pump, a changing vibration frequency can be corrected by changing the engine speed.

  • one configuration option is that at least one of the potentially faulty operating states of the fault list is linked to a control or regulation instruction, with the fault determination unit being designed to control the compaction drive when this faulty operating state is determined in accordance with the control or regulation instructions.
  • the control or regulation instruction can also be a deactivation, in particular of the compression drive.
  • the soil compacting machine has a data interface which is coupled to the operating state determination device to output some or all of the operating states and/or which is coupled to the error determination unit to output the error messages.
  • the data interface is preferably designed to be wireless. Data transmission is correspondingly simple, and a connector that would otherwise be necessary cannot get dirty.
  • the wireless data interface can be, for example, an NFC (near field communication), RFID (radio-frequency identification), Bluetooth (a WPAN standard (Wireless Personal Area Network - standard), WLAN (wireless local area network), WAN (Wide Area Network) or telephone network interface

  • WLAN wireless local area network
  • WAN Wide Area Network
  • telephone network interfaces can be individualized for the owner of the soil compaction machine.

On the other hand, it is often sufficient for small companies to have this data locally, which is why NFC is more suitable , RFID, Bluetooth and WLAN.
  • the data interface is designed to receive service data and output it via the screen, in particular also live data or direct transmission data from a service.
  • service data can be uploaded, such as updated operating instructions or real-time advice on troubleshooting.
  • the compaction plate is driven by the compaction drive via a V-belt
  • the operating state determination device is designed to determine V-belt wear of the V-belt based on a determination of a motor speed of the compaction drive and an oscillation frequency of the compaction plate, with a potential faulty operating state in the fault list shows excessive wear of the V-belt.
