Definitions

  • the present invention relates to a load-handling device for cable lifts with integrated load measuring device, in which the weight of load-carrying means and payload causes the load-proportional deformation of at least one elastic element, wherein at least one sensor detects this deformation and a strength of the deformation and thus the load representing Generates signal to an elevator control.
  • Load measuring devices for load-handling devices of elevators have the task of preventing an elevator travel with an unacceptably high load and to provide the elevator control with information that allows it to respond to call commands by elevator users in a suitable manner, depending on the current load condition of the load handling device.
  • EP 0 151 949 discloses a load-sensing device for an elevator elevator, which is based on the principle that the entire elevator car is supported on at least four horizontally projecting from an elevator floor frame bending beams, that these bending beams undergo a load-proportional deflection. The deflection of each individual bending beam is detected by means of strain gauges. All strain gauges together form a measuring bridge, which supplies a load-proportional analog signal to the elevator control.
  • the described load measuring device has some disadvantages.
  • the measuring principle requires four bending supports equipped with one or two strain gauges, whereby the mechanical tolerances of the bending beams as well as the resistance tolerances and mounting tolerances of the strain gauges are to be limited so tightly that all four bending sensors have the same resistance values for the same loads. All four or eight strain gauges are to be individually connected to a central evaluation circuit, which causes considerable expense. In addition, the four force introduction points between the bottom of the elevator car and the bending beams are to be adjusted vertically during installation so that an acceptable power distribution is ensured.
  • the present invention has for its object to provide a simple and cost-effective load-measuring device for load-carrying means of lifts with underlayment cable drive, which does not have the disadvantages mentioned above.
  • the inventive load-handling device for cable lifts with integrated load measuring device has significant advantages.
  • the elastic horizontal bending beam, whose deformation caused by the weight of the lifting device is detected by the sensor, is the supporting structure with which the pulleys are attached to the load-carrying means. As a result, essentially no additional mechanical construction elements and no additional installation space for the load measuring device are required.
  • the load-dependent deformation of the bending beam is detected by a sensor. This allows optimally adapted load measuring devices to be designed.
  • inventions of the inventive load-carrying means with integrated load measuring device can be achieved by the use of adapted to geometric conditions, environmental influences and in particular to accuracy requirements sensor principles.
  • the invention allows the use of a variety of sensors for detecting deformation, such as strain gauges, vibrating string sensors, opto-electrical distance or angle sensors and inductively or capacitively acting distance sensors.
  • Load-bearing devices for larger loads are usually equipped with a support frame.
  • load handling devices for smaller payloads, these can be designed as a self-supporting unit.
  • the supporting structure (s) carrying the sheaves and containing the elastic bending beam are in this case advantageously fastened directly to the floor construction of the load receiving means.
  • FIG. 1 shows a carrying frame-free load-bearing means 1 according to the invention with the lift components most important for its function.
  • two guide rails are referred to which by means of sliding or roller guide shoes 3, the load-carrying means is guided vertically.
  • This consists essentially of a bottom frame 4 with bottom plate 5, a built thereon cabin 6, said sliding or roller guide shoes 3 and two by means of a support structure 7 via elastic isolation elements 8 on the bottom frame 4 fixed pulleys 9.
  • the support structure 7 consists of a bending beam 7.1 and two pulley supports 7.2.
  • a support cable 10 which is guided vertically downwards from a cable fix point 11, then horizontally under the pulleys 9 of the load-receiving means 1 and then vertically upwards to a traction sheave 12 of an elevator drive machine 13. Not shown here is the further course of the support cable 10 from the traction sheave 12 down to a mounted on a balance weight deflecting plate and from there upwards to a second rope set point.
  • each of the two pulleys 9 each acts a vertical and horizontal load-proportional cable traction.
  • the arrows 14 symbolize the on the pulleys 9 and thus on the Support structure 7 acting, resulting from the Seilkzugräften the suspension cables pulley loads. It is readily apparent that these resultant in the bending beam 7.1 of the support structure 7 generate a bending moment and thus a deflection.
  • This deflection is detected by a bending sensor 15, for example a strain gauge sensor, which is not explained here in more detail, and generates a signal corresponding to the magnitude of the deflection and thus the total weight of the load receiving means 1 as input for an elevator control.
  • Fig. 2 is a variant of a load-carrying means with integrated load measuring device shown. Visible are the means of sliding or roller guide shoe 3 guided on guide rails 2 load-carrying means 1 with bottom frame 4, bottom plate 5 and cab 6.
  • the supporting the pulleys 9 support structure 7 consists essentially of one, via elastic insulation elements 8 on the bottom frame 4 mounted mounting bracket 17 and two Pulley Supports 18.
  • the pulley support, not shown here, arranged on the right corresponds to the pulley supports according to FIG Fig. 1 ,
  • the left-side pulley support 18 is articulated by means of a bending element 19 on the mounting bracket 17 and supported by a pressure sensor 16 with respect to this.
  • the articulated attachment of the pulley support 18 could also be achieved with a hinge axis.
  • the resulting from the Seilkzugräften the suspension cables pulley load 14 causes a load-proportional pressure force on the pressure sensor 16, which also forms the elastic element, and generates a the total weight of the load receiving means 1 corresponding signal as input for an elevator control.
  • the pressure sensor can be designed, for example, as a piezoelectric element, as a capacitive sensor or as a strain gauge element.
  • Fig. 3 shows a further variant of a lifting device with integrated load measuring device. Visible are in turn guided by means of sliding or roller guide shoe 3 on guide rails 2 load-carrying means 1 with bottom frame 4, bottom plate 5 and cab 6.
  • the supporting the pulleys 9 support structure 7 consists essentially of one, via elastic insulation elements 8 mounted on the bottom frame 4 with a left-side Bearing support 20 and two pulley supports.
  • the not shown here, right arranged pulley support corresponds to the pulley supports according Fig. 1
  • the left-side, designed as a pivot lever pulley support 21 shown here is attached to a torsion bar 22 and rotatably mounted on this in the associated with the mounting bracket 17 bearing support 20.
  • a stop 23 prevents overloading of the torsion bar 22. This is extended beyond the bearing support 20 to the rear (in the drawing plane) and connected at its rear end against rotation with the mounting bracket 17.
  • the resulting from the Seilkzugräften the suspension cables pulley load 14 causes via the designed as a pivot lever pulley support 21 a load proportional torque, which twists the torsion bar 22 and causes in this corresponding load-proportional torsional stresses.
  • a Verwars sensor in the form of strain gauges
