Definitions

  • the invention relates to a control of a rope-drawn load suspension device on the guide rails of an inclined elevator having a plurality of telescopic sections using a hydraulic drive for the load suspension device and the stop position determining switching devices arranged on the guide rails or attachments thereof and on the load suspension device on the other hand.
  • the object of the invention is to improve the determination of the holding position, i.e. Eliminate interferences such as different loads, viscosity fluctuations and rope elasticity.
  • an elaborate and fault-prone transmission of the position of the load suspension device in the upper region of the inclined elevator should be dispensed with.
  • the soft start-up characteristics achievable according to the older proposal both when opening the load suspension device and when moving it down should be retained.
  • distance measuring devices are provided both in the upper region of the upper guide rail and in the lower region of the lower guide rail in such a way that the load-carrying means traverses corresponding contacts depending on the path, the contacts passed over the upper region being converted into impulses which are generated by means of a multi-channel radio transmitter to a receiver, which is preferably assigned an amplifier, in the area of the hydraulic drive on the chassis of the inclined elevator.
  • the magnetic field of the proportional valve can be infinitely or gradually influenced and the proportional valve can be switched in a new way depending on the path, so that the load suspension device can be braked gently in a definable end position. Since relatively little energy is required for the transmission of the radio impulses, there is no need to carry a cable along the length of the inclined elevator and the transmitter located in the upper region of the inclined elevator can be supplied with energy via an accumulator.
  • the position of the load suspension device can be tapped by means of an inductive proximity switch, to which, for example, a perforated strip is assigned, by means of a potentiometer or also by means of a light barrier or the like.
  • the hydraulic motor driving the load winch of the load rope is in turn driven by a gasoline engine.
  • the invention proposes that the control of the gasoline engine is included in the control by the displacement measuring device in such a way that an electromagnet is assigned to the gasoline engine according to claim 6, which immediately switches to full throttle when the gasoline engine is started, the electromagnet in connection with a The timer automatically releases the automatic start-up when starting the load (i.e. when the proportional valve begins to switch) after a period of time within which the petrol engine has reached its full speed.
  • the "full gas magnet" is opened by the last pulse from the displacement measuring device, ie the gasoline engine is automatically switched to idling speed. It is thus ensured that the application of the hydraulic motor is regulated depending on the position measuring device.
  • the present invention not only achieves a precise approach to the stop position of the load handler, but this precise approach takes place smoothly and smoothly, because the switching of the proportional valve is path-dependent and thus regulates the oil flow supplied to the hydraulic motor and the oil flow released to the hydraulic motor can be that the stop position is approached softly.
  • the figure shows a schematic representation of an inclined elevator with a furniture platform
  • the inclined elevator designated 1 has the telescopic guide rails a - d, which are supported on a chassis 2.
  • the inclined position of the guide rails can be changed using an inclination adjusting cylinder 3.
  • the furniture platform designated 6 must assume an exact stop position if the furniture is to be brought into the interior of the building.
  • the furniture platform 6 can be moved by means of a slide 7 on the guide rails a - d of the inclined elevator 1.
  • the hydraulic drive 8 which essentially consists of a gasoline engine and a hydraulic pump and the associated control devices.
  • the hydraulic drive 8 acts on a load winch, designated 15, which serves to receive the load rope for driving the carriage 7.
  • the displacement measuring device 9 shown for example, consists of an inductive proximity switch 13 arranged on the upper rail d on the one hand and on the lower rail a on the other hand, which interacts with a perforated strip 14 arranged on the carriage 7.
  • the Carriage 7, shown in solid lines in the upper position passes over inductive proximity switch 13 with perforated strip 14, the pulses being transmitted wirelessly to the area in accordance with the number of holes passed by means of a radio transmitter 10 - which is fed via an accumulator (not shown) of the drive arranged receiver 11 are transmitted.
  • the pulses received by the receiver 11 are fed to a proportional valve arranged in the control block of the hydraulic drive 8 - for example via a cable connection 12 - so that the proportional valve regulates the amount of oil to be supplied to the hydraulic motor or the flow rate in the hydraulic motor according to the received pulses can control.
  • the pulses can be transmitted directly to the hydraulic drive via cables.
