Definitions

  • the invention relates to a device for Synchronization of telescopic stamps at Hydraulic lifts.
  • From CH 463 745 is a hydraulic or pneumatic synchronous telescopic stamp with two or more of the pressure medium applied directly, from one Cylinder telescopic pistons became known in which between the telescopic parts attacking, mechanical connection means available which are evenly divided in each stroke position Partial strokes between the successive telescopic parts force.
  • mechanical fasteners especially chains or ropes not further described used, which are to be deflected via rollers.
  • chains and gears have deflections the disadvantage that they generate vibrations that are on the pistons and transferred to the cabin.
  • the general Such pistons can be used up to Range from 5-10 tons of payload. That throws the Problem on that with increasing payload, for Synchronization of the piston stages, forces are achieved by dimensioning the chains accordingly can be implemented. Nevertheless, the increases not necessary space for the chain deflection wheels.
  • Practice shows the fewer points of intervention by the Chain in the chain deflection wheel, the bigger the frequencies by the combination chain and Chain deflection wheel are generated.
  • the invention has for its object a Device for synchronization of telescopic stamps at Hydraulic lifts of the type mentioned at the beginning to propose which the disadvantages mentioned above are not having.
  • the advantages achieved by the invention are in essential to see that in the case of jacketed Synthetic fiber ropes with significantly smaller bending radii same power transmission compared to steel cables can be realized.
  • the small deflection radii at Chains can be taken from the synthetic fiber ropes or can even be downsized without the disadvantageous, positive contact points of the chain in the Take over chain deflection wheel.
  • Synthetic fiber rope must also be in operation, due to negligible linear expansion, no more be readjusted.
  • an elevator for example a panoramic elevator the sheathing of the synthetic fiber rope with any Color or logo.
  • the synthetic fiber rope in a simple way with a Device for precautionary fault detection based on possible wear.
  • 1 is a shaft and 2 is a shaft base called a hydraulic elevator system.
  • On the Schachtground 2 is a foot part 3 for holding a Telescopic stamp 4 of the hydraulic elevator system attached.
  • the telescopic stamp 4 consists of a Cylinder 5 with a first piston 6 and a second Piston 7.
  • the arrangement of the telescopic ram 4 in the shaft 1 takes place depending on the elevator design, for example as Backpack arrangement with a telescopic stamp 4 or as Tandem arrangement with two or more telescopic stamps 4.
  • the first piston 6 and the second piston 7 are off the starting position (shown with dashed lines) the cylinder 5 extendable when hydraulic Pressure medium, for example oil, not from one here Pump shown further via an inlet opening 8 in Foot part 3 is pumped in. Likewise, when draining of the pressure medium, the two pistons 6, 7 again into the Starting position can be returned.
  • hydraulic Pressure medium for example oil
  • both pistons 6, 7 are moved synchronously.
  • Connecting means 10 in the form of a synthetic fiber rope, attached, the one arranged on the first piston 6 Roll 11 is deflected and at a suitable height Fastening device attached to the shaft wall 12 is fixed.
  • the synthetic fiber rope 10 instead of Chains, as a mechanical fastener, is one considerable reduction in the generated during operation Vibrations possible.
  • the synthetic fiber rope also prevents 10 a transmission of in the telescopic stamp 4, respectively. the Pistons 6, 7, generated frequencies so that there is noise in shaft 1 no further via synthetic fiber rope 10 can spread.
  • the synchronization is also on a telescopic stamp 4 with a cylinder 15, a first piston 16, a second piston 17 and one third piston 18 possible.
  • the first piston 16 and the second piston 17 as below Fig.1 described interconnected.
  • the second and the third piston 17, 18 are also with a Synthetic fiber rope 20, however, on the second piston 17 and on third piston 18 is deflected via rollers 21, connected with each other.
  • the synthetic fiber rope is 10 one end on the second piston 17 and the other end on the Fixed shaft wall. Because of the used Synthetic fiber ropes 10, 20 can have slidably mounted rollers 11, 21, for example made of polyamide.
  • FIG 3 shows a perspective view of the Synthetic fiber rope 10, 20 as a connecting means.
  • a Sheath 24 surrounds an outermost strand layer 25.
  • the casing 24 made of plastic, preferably Polyurethane is the coefficient of friction of the synthetic fiber rope 10, 20 variably adjustable on the rollers 11, 21.
  • the coefficient of friction of the casing 24 on the rollers 11, 21 can due to different properties of the surface of the Jacket 24 can be defined (for example, smooth or structured).
  • the load-bearing strands 26 are made from individual aramid fibers 30 rotated. Each individual strand 26 is used to protect the Aramid fibers 30 with an impregnating agent, for example Treated polyurethane solution.
  • the ability to change bends of the synthetic fiber rope 10, 20 is dependent on the proportion of Polyurethane in each strand 26. The higher the proportion of Polyurethane, the higher the alternating bending power.
  • the polyurethane portion for impregnating the strands 26 can, depending on the desired bending alternating power Example are between ten and sixty percent.
  • the roll diameter for synthetic fiber ropes moves in Range of 10 to 20 times the rope diameter.
  • a diameter of the synthetic fiber rope 10, 20 of approximately 6-10mm results in a diameter for the rollers 11, 21 in the range of approximately 140mm.
  • a rope diameter from 10-15mm you would have a roll diameter of 300-450mm need.
  • a Elevator for example a panoramic elevator, can Sheathing 24 of the synthetic fiber rope 10, 20 with each any color or logo.
