Definitions

  • the invention relates to a method for lifting and / or lowering a building according to the type specified in the preamble of claim 1 and a measuring device for performing the method.
  • the control of the individual lifting cylinder groups or the mutual coordination of their stroke paths is accomplished by imparting a pressure medium quantity metering.
  • the lifting cylinders of systems for lifting buildings are preferably combined in three lifting cylinder groups, the lifting cylinders of each group being communicatively connected to one another and each lifting cylinder group being assigned its own pressure medium source.
  • Each lift cylinder group is only equipped with a device for stroke travel detection.
  • the lifting cylinder groups are simultaneously pressurized and the lifting process is only checked on the basis of the stroke. With different load conditions or in the event that the subsoil or the foundations give way, the pressure within the higher-loaded cylinder group increases automatically. This increase in pressure is not monitored with this method and, if the load is too high, could cause the failure of an entire cylinder group and the building would not be protected against cracking or a sudden redistribution of loads.
  • Another method is known from DE-OS 30 23 892 in which the starting position of the building is optically measured as the actual value and fed to a central controller. This compares the actual value with the building dimensions and the positions of the lifting cylinders and forms target values for the individual lifting cylinders. After the stroke, the individually measured stroke distances are fed via the individual controllers to the central controller, which checks and determines new setpoints. If the actual stroke distances do not correspond to the specified ones in the event of faults, a signal is triggered and the lifting process is interrupted. The individual values are not linked to one another so that the lifting cylinders are controlled without taking into account the other lifting cylinders and their behavior. This leads to the fact that the lifting process has to be interrupted with each stroke deviation without an attempt to compensate. A pressure measurement is also not carried out so that monitoring of the support forces and their changes is not possible.
  • the lifting devices are controlled only on the basis of the distance-target-actual comparison. With oil pressure it is only checked whether the value is still within the permissible range. If the range is exceeded or undershot, the lifting process is stopped as a result of an alarm.
  • the pressure values are therefore only compared with the limit values and the monitoring of a possible change in the pressure values, e.g. due to the successive polling of individual lifting devices does not take place. Since a pressure deviation in the lifting devices reflects the changes in the support forces, monitoring the pressure deviation could not only keep the load limits of the lifting devices and the building at this point, but also compensate for excessive changes in the support forces if necessary by actuating other lifting devices.
  • the invention has for its object to provide a method for lifting and / or lowering a structure and a measuring device for performing the method, while avoiding the disadvantages of the known methods mentioned above, which the behavior of the structure and the lifting devices during the lifting, or Lowering process is better monitored and thus the lifting and / or lowering of structures that can be damaged even with smaller load redistributions is made possible.
  • the invention is based on the knowledge that the control of all individual or grouped lifting devices takes into account deviations and / or faults in other lifting devices.
  • the procedure is explained below:
  • the pressure and stroke values of the individual lifting devices are queried sequentially and transmitted to a central processing unit via data lines. These values are then compared with values stored in a central memory Facility are recorded, compared individually.
  • the output pressure values, the limit pressure values, the output and the end level of the individual lifting devices determined on the basis of the structural statics are recorded in the memory of the central device.
  • the positions of the lifting devices which could be combined as a group with the individual lifting device, are also recorded in the memory. If deviations in value or exceeding or falling short of values are determined in the comparison, the relevant lifting device or another lifting device or lifting devices is controlled using an allocation memory in order to remedy this deviation.
  • the method according to the invention further provides that lifting cylinders, which are arranged as support points under a rigid element in the building and have the same pressure values combined as a group, can be actuated simultaneously.
  • This also applies analogously to several lifting devices which are arranged under a support point.
  • the lifting devices that have been combined into a group can be controlled separately at any time.
  • an individual lifting order can be determined, which is always only the number of lifting cylinders controls at the same time that are required for safe lifting of the structure.
  • the other lifting cylinders are then actuated one after the other, so to speak. The maximum power requirement is thus reduced without causing damage to the structure.
  • the level of the individual lifting devices is determined using a differential measurement.
  • An electronic hose scale is preferred as the measuring device. From a reference point, hoses are placed on each lifting device and filled with water or another liquid. At the end of the hoses, in the area of the lifting device, the inner walls of the hoses are provided with capacitive sensors. The capacity of the transducers drops with a falling liquid level. During the lifting process, the liquid level in the hose drops and the capacity of the transducers decreases.
  • the capacity values are queried sequentially during the lifting process and, as already described, transmitted to the central processing unit via data lines.
  • the capacity of the hoses of the individual lifting devices is compared with the capacity of the reference point in the computing unit and the capacity difference is determined.
  • the level difference value can be calculated on the basis of this capacity difference. This is then compared with the previous measured value and the difference gives the stroke of the lifting device.
  • a number of lifting devices is stored in the memory, the level measurement values of which are compared with the level measurement value of the lifting device. If a predefined radius of curvature is exceeded in the comparison, the relevant lifting device or another lifting device or lifting devices is controlled on the basis of the allocation memory in order to remedy this exceeding.
  • Fig. 1 the block diagram of the stroke control is shown.
  • the data relating to pressure, level and height change ascertained by the measuring device 2, 3, 19 connected to each lifting device 1 each reach the central processing unit 8 of the central device 13 via an input / output unit 4 and a serial data bus 5 Input / output units 4 as microprocessors and the central processing unit 8 as an industry standard PC.
  • the PC has one Main memory (RAM) 9 and a program and mass storage 12 in the form of disk and floppy disk drives.
  • the measurement data are compared individually via address bus lines 6 with the data in the assignment tables 10 in the main memory (RAM) 9, taking into account the specifications in the mass memory (ROM) 12.
  • the individual or predetermined groups of lifting devices 1 are controlled by the input / output unit 4 according to the predetermined sequence in the mass memory (ROM) 12.
  • the valve 17 and the hydraulic unit 14 are opened and the displacement transducer 19 measures the change in height on the lifting device 1 or in the niche 25.
  • the program is stored in the variable allocation memory 11 accessed and carried out step by step. After the program has run, the measuring devices 2, 3, 19 are queried again and compared with the data in the assignment tables 10 in the main memory (RAM) 9, taking into account the specifications in the mass memory (ROM) 12.
  • the individual or predefined groups of lifting devices 1 are controlled by the input / output unit 4 in the predefined sequence in the mass memory (ROM) 12. If deviations or exceeding or falling short are still detected, an alarm signal is issued and the lifting process is interrupted.
  • ROM mass memory
  • lifting device 1 Only one lifting device 1 has been shown schematically in the figure, but it is possible, as already described in detail in the preceding description, one large number of lifting devices 1, which are required, for example, when lifting a larger building, to be controlled individually or in groups from this central device 13.
  • Corresponding assignment (programming) with regard to the pressure values to be expected can, in a preferred embodiment, also be used to switch the comparison patterns by means of logical links.
  • a lifting device is shown schematically.
  • the lifting device 1 is installed under a wall 24 in a niche 25.
  • the hydraulic unit 14 has an inlet 15 and an outlet line 16 in which control valves 17, 18 are installed.
  • the pressure sensor 2 is arranged behind the control valve 17 in the inlet line 15.
  • the displacement sensor 19 is designed as a wire rope displacement sensor and is attached between the lower and upper edge of the recess 25.
  • the displacement sensor 19 can also be designed as a linear displacement sensor and is then arranged between the fixed and movable part of the lifting device 1.
  • the level measuring device consists of an electronic hose scale 3.
  • a hose 20 is attached to the rear of the lifting device 1 and is equipped with a capacitive sensor 21 on its inner wall.
  • the other end of the hose 20 is designed in the same way and is fixed at the reference point 22.
  • Hose lines are laid from reference point 22 to all lifting devices 1 and capacitive sensor 21 is also provided with a microprocessor-controlled input / output unit and communicates with central device 13 via the same serial data bus 5 as lifting devices 1.
  • the pressure values, the level and the last travel distance traveled can be measured or ascertained.
  • the embodiment of the invention is not limited to the preferred exemplary embodiment specified above. Rather, a number of variants are conceivable which make use of the solution shown even in the case of fundamentally different types.
