Definitions

  • the invention relates to an industrial truck with a load carriage that can be raised and lowered on a lifting frame, on which a fork carriage that can be tilted about a horizontal pivot axis is arranged, on which a load handling device for taking up a load is arranged, with a tilting cylinder device being provided with which the fork carriage can be rotated the horizontal pivot axis can be tilted.
  • Such industrial trucks can be designed as stacker trucks or reach trucks, in which a load carriage can be raised and lowered on a mast.
  • a fork carriage is arranged on the load carriage, on which a load handling device for receiving a load is arranged.
  • the load handling device is usually formed by a load fork with two forks.
  • the mast is generally non-inclinable.
  • the center of gravity of a lifted mast could be determined by additionally detecting forces or the hydraulic pressure in the tilting cylinders of the mast to determine the load when the load weight is known.
  • the determination of the forces of the tilting cylinders based on the hydraulic pressure is dependent on friction and viscosity and therefore only allows limited accuracy when calculating the center of gravity of the load.
  • the present invention is based on the object of providing an industrial truck of the type mentioned at the outset which, with regard to the determination the forces acting on the tiltable fork carriage in the area of the tilting cylinder device are improved.
  • an intermediate piece is arranged between the tilting cylinder device and the fork carriage, which intermediate piece transmits the forces of the tilting cylinder device to the inclinable fork carriage, the intermediate piece being provided with a sensor system for measuring the forces acting on the inclinable fork carriage in the area of the tilting cylinder device .
  • the intermediate piece arranged between the tilting cylinder device and the fork carriage which is provided with a sensor system for measuring the forces acting on the tiltable fork carriage in the area of the tilting cylinder device and is therefore equipped with a corresponding sensor system, thus forms a measuring body with which the forces acting on the tiltable fork carriage in the Forces acting on the area of the tilting cylinder device can be determined.
  • the measuring body arranged between the tiltable fork carriage and the tilting cylinder device enables increased accuracy when determining the forces acting on the tiltable fork carriage in the area of the tilting cylinder device and thus achieves increased accuracy when determining the position of the load center of a load picked up on the load handling device, since the friction within the tilting cylinder device and the viscosity of the pressure medium do not affect the measurement result.
  • the intermediate piece extends in the transverse direction of the fork carriage and the tilting cylinder device has a first tilting cylinder, which is supported on a first end area of the intermediate piece, and a second tilting cylinder, which is supported on a second end area of the intermediate piece, wherein the sensor system has a first sensor device arranged in the first end area of the intermediate piece and a second sensor device arranged in the second end area of the intermediate piece.
  • the intermediate piece designed as a measuring body is therefore provided with two measuring points, at each of which a sensor device is provided in order to determine the forces acting on the tiltable fork carriage in the area of the tilting cylinder device.
  • the intermediate piece is provided with a recess to accommodate the sensor system.
  • the sensor device can be installed in a protected manner in a corresponding recess.
  • the recess is advantageously arranged vertically in each case.
  • the forces acting on the tiltable fork carriage in the area of the tilting cylinder device lead to deformations on the measuring body about a vertical vertical axis. If the recess is also arranged vertically, the forces on the fork carrier lead to corresponding deformations on the walls of the recesses, which can be used and measured with the sensor device for determining the forces acting on the fork carrier.
  • a strain measurement of the intermediate piece is carried out with the sensor device.
  • the force measurement to determine the forces on the fork carriage in the area of the tilting cylinder device is therefore based on the principle of strain measurement.
  • the sensor device is preferably formed by strain gauges (DMS), with which the strains occurring under load and thus deformations of the intermediate piece are detected.
  • DMS strain gauges
  • each sensor device carries out a redundant force measurement.
  • the redundancy can take place, for example, in that each sensor device has a strain gauge full bridge. This achieves a high level of operational reliability for determining the forces acting on the tiltable fork carriage in the area of the tilting cylinder device.
  • the intermediate piece is provided in each end area with a slot-shaped recess running in the transverse direction of the fork carriage, which extends along the support of the tilting cylinder device and the recess of the sensor system and divides the intermediate piece into two plate-like end area sections, with a first end area section the tilting cylinder device is supported and the recess of the sensor system is arranged and the fork carriage is supported on the second end region section.
  • a slit-shaped recess in the intermediate piece it can be achieved in a simple manner that under load, i.e. a load taken up by the load-carrying means, corresponding deformations occur on the first end region sections which, with the sensor devices arranged in the two recesses, are used to determine the forces be detected by the fork carriage.
  • a mechanical stop is provided in the area of the slot-shaped recesses, which limits the deformation of the first end area section.
  • the intermediate piece designed as a measuring body is therefore additionally provided with a mechanical stop as overload protection. Before excessive loading of the intermediate piece leads to plastic deformation of the intermediate piece, the gaps formed by the slot-shaped recesses in the intermediate piece are closed by the mechanical stop becoming effective, so that the forces are transmitted directly between the tilting cylinder device and the fork carriage via the mechanical stops will.
  • the mechanical stop is advantageously formed by an elevation arranged on the first end area section or on the second end area section, which elevation extends into the slot-shaped recess and reduces the width of the slot-shaped recess.
  • the elevation arranged on the first end area section or on the second end area section comes into mechanical contact with the second end area section or the first end area section and closes the gap between the two end area sections.
  • the survey is preferably arranged in extension of the tilting cylinder device, whereby with effective mechanical stop a favorable power flow between the tilting cylinder device and the fork carriage is achieved.
  • the intermediate piece can be designed in one piece.
  • the intermediate piece can be designed in several parts, in particular in two parts, with the second end region sections being formed by a plate which is fastened to the intermediate piece.
  • the manufacture of the slit-shaped recesses can be carried out in a simplified and more cost-effective manner in the case of a two-piece intermediate piece.
  • the sensor system is connected to an electronic control device, which is connected to a sensor device that detects the load weight of a load on the load handling device, the control device being designed in such a way that the load weight and the Forces together with values stored in the control device for the geometry of the fork carriage, the horizontal distance of the center of gravity of the load from the fork carriage and/or the load moment of the load is determined.
  • the distance between the horizontal swivel axis of the fork carriage and the support points of the tilting cylinder device on the intermediate piece is known, and the values for the geometry of the fork carriage are therefore known, if the load weight is known and by means of the forces of the fork carriage in the area of the tilting cylinder device recorded by the sensors of the intermediate piece, this can be done on the basis of a moment equilibrium around the swivel axis the horizontal distance of the center of gravity of the picked-up load from the fork carriage and/or the load moment of the picked-up load can be calculated in the electronic control device.
  • the sensor device that detects the load weight of a load located on the load-carrying means can, for example, detect the hydraulic pressure in a lifting hydraulic system of the load carriage.
  • the load weight of a load on the load handling device can be measured directly with a force measuring sensor system that, for example, records the force on a lifting chain that actuates the load carriage or that is integrated directly into the load handling device, for example fork tines with an integrated force measuring sensor system.
  • the horizontal distance of the center of gravity of the load and/or the load moment can be used for assistance and/or safety systems of the industrial truck in order to be able to determine the position of the overall center of gravity of the industrial truck. If predetermined critical results are exceeded, the assistance and/or safety systems can issue a warning and/or intervene in the vehicle control. In this way, the driver of the industrial truck can be informed and/or supported in the event of critical load conditions. For example, a warning can be given if the load is positioned too far forward on the load handling attachment for a specific load weight, so that there is a risk of the industrial truck tipping forward. It is also possible to intervene automatically in the truck control, e.g. to stop the industrial truck in such critical situations or to adjust the driving speed accordingly. In such situations, the mast can also be automatically tilted back or the lifting height can be automatically limited. Accidents and transport damage can thus be avoided.
