Definitions

  • the invention relates to a machine room-less, hydraulic elevator system with any in the building arranged drive system in a cabinet.
  • DD 267 971 is an electro-hydraulic elevator become known, the one with a multiplier is equipped and in which the hydraulic drive and the control unit outside the elevator shaft positions not defined in more detail are arranged, whereby for the accommodation two separate, no further described boxes are provided.
  • the hydraulic Drive is via pressure lines to the working cylinder connected.
  • Elevator was a solution for a hydraulic one To develop a lift with a long stroke length. Here there was also no separate machine room. Drive and control are only in with this solution simple boxes. Hydraulic drives, especially the pump, generate during operation however, a high, uncomfortable noise level that undamped neither the residents of a house nor that Staff of a commercial building can be expected. Out for this reason, drive system and drive control conventionally e.g. in basements with little Utility value. It is further desirable that in the event of damage to the drive or the Oil tank outflowing oil can be collected safely. In addition, the previously known arrangement of drive and Control requires a large footprint.
  • the present invention is based on the object a machine-room-less, hydraulic elevator system to propose which the disadvantages mentioned above are not and in which the drive system (drive and Control) is built to save space and is good in the building accessible at any place can, without using adjacent rooms affect.
  • Fig.1 shows a floor plan of a hydraulic Elevator system 1.
  • a shaft 2 there is a load cabin 3 by means of a hydraulic cylinder 4 up and down emotional.
  • the arrangement of the hydraulic cylinder 4 in the shaft 2 takes place depending on the elevator design, for example as Central lift or backpack arrangement with one Hydraulic cylinder 4 or as a tandem arrangement with two Hydraulic cylinders 4. Allows 5 on each floor a shaft door 6 gives access to the elevator car.
  • the Landing door 6 can be an automatic telescopic door simple central opening or also a central opening Be telescopic door. Use would also be possible a swing door.
  • a Cabinet 10 placed. This cabinet 10 contains that entire drive system.
  • a pressure line 20 is the hydraulic pump 16 via the Valves 18 connected to the hydraulic cylinder 3.
  • the cabinet 10 with a lock provided, pivotable doors 22 equipped. At opened doors 22 can be maintenance or Assembly / repair work on the drive system will.
  • the placement of the cabinet 10 is not only on restricted the area next to the shaft door 6.
  • the drive system finds the small dimensions in a narrow cabinet 10 places, which makes it practical can be placed anywhere in a building. This is preferably close to traffic routes in Utility rooms or in corridors where a good one Accessibility is guaranteed. This allows you to high cost separate machine room to be dispensed with.
  • the entire drive system can already be Factory prefabricated, or in the cabinet 10 to be built in.
  • the cabinet 10 is built with the Drive system delivered to the elevator system 1, with what the assembly and installation work on the Setting up closets 10 and laying the Limit pressure line 20.
  • FIGS. 2a and 2b show a schematic view and a floor plan of the cabinet 10 with the drive system.
  • the electric motor 15 and the hydraulic pump 16 can be in the cabinet 10 either vertically or horizontally to be ordered.
  • the electric motor 15 and the hydraulic pump 16 are in this vertical or horizontal position in the oil tank 17, where it from Hydraulic oil are housed.
  • the cabinet 10 itself is sealed so that that no hydraulic oil can leak. A separate Oil pan is therefore unnecessary.
  • Control part 19 consists essentially of a Cabin control 30 and a drive control 31.
  • Die Drive control 31 can, as is common today, be equipped with relays. However, there is also advantageous possibility of a so-called soft starter, using thyristors. Thereby are the mechanical disturbing in certain cases Switching noise of the relays eliminated. In this manner the entire control part 19 works practically noiseless.
  • the method of controlling the valves 18 takes place in accordance with that described in EP 0 643 006 Procedure that a direct entry on a floor enables without driving at crawl speed. By this process significantly reduces the hydraulic oil warmed than in processes in which shortly before reaching of the floor to a small, constant Creep speed is switched.
  • the Oil tank 17 In the bottom part of the cabinet 10 is the Oil tank 17 and in a vertical or horizontal arrangement the electric drive 15 and the hydraulic pump 16.
  • the valves 18 are positioned above the oil tank 17.
  • Of the Control part 19 with the cabin control 30 and Drive control 31 is on the walls in the upper part of the Cabinets 10 housed.
  • the door 22 provided with a lock 32 covers in closed state the entire drive system completely.
  • the cabinet 10 is not as Elevator drive recognizable.
  • a first layer of insulation 35 encloses the entire oil tank 17, which also the electric motor 15 and the hydraulic pump 16 contains.
  • a second insulation layer 36 is on the Walls of the cabinet 10 attached.
  • the Insulation layers 35, 36 consist of commercially available Insulating mats.
  • Fig.2c shows a side view of the cabinet 10.
  • the cabinet 10 in direct connection to the shaft 2 to Example attached next to the shaft door 5, one Airflow LF through openings in the rear wall of the cabinet 10 by means of a fan 40 and via the shaft 2 respectively.
  • the fan 40 arranged above the oil tank 17 and the oil tank 17 with a cover 41 provided on three sides with the Cabinet 10 is tightly connected. By the fan 40 air is now through a first opening 42 in the rear wall sucked.
