Definitions
- the invention relates to a hydraulic elevator in the Preamble of claim 1 mentioned type.
- Such lifts used for example in residential and commercial buildings, where they Transport of people and / or goods between different Serve floors.
- a hydraulic elevator in the preamble of claim 1 mentioned type is from DE-A1-30 02 577 for a long time known. Inside the elevator shaft is a vertical one Piston rod firmly anchored, on top of which the elevator car a deflected rope driving cylinder is movable. On a counterweight is arranged at the same time on this cylinder.
- the Cylinder has two cylinder spaces of the same cross-section, see above that the cylinder is movable on the piston rod in that using a pump hydraulic oil between the two Cylinder rooms is pumped over.
- the hydraulic oil is the Cylinder chambers are fed through blind bores in the piston rod.
- the unit consisting of piston rod and cylinder including counterweight can pre-assembled in the manufacturing plant and then by means of a mobile crane be used in the elevator shaft at the construction site. It is then required on site, the unit of engine and Connect the pump to the piston rod via hydraulic lines. It can be problematic to have the hydraulic rooms air-free Fill hydraulic oil or vent after assembly.
- the invention has for its object a hydraulic To create elevator system in which the hydraulic unit as Everything can be pre-assembled in the factory.
- a piston rod 2 by means of means 3 which are only indicated symbolically is attached.
- Piston 4 With this piston rod 2 is firmly connected Piston 4.
- a cylinder 5 can be moved along the piston rod 2, on the inside of the piston 4 rests.
- the first pressure chamber 6 is through a first hydraulic line 8 with one side of a pump 9 connected, while from the second pressure chamber 7 a second Hydraulic line 10 leads to the other side of the pump 9.
- the Pump 9 is connected to a motor 12 by means of a shaft 11.
- This motor 12 is controllable in its direction of rotation and adjustable in terms of its speed. Between the two Pressure chambers 6, 7 is thus hydraulic oil by means of the pump 9 umpumpbar. Is by means of in the first direction of rotation operated pump 8 hydraulic oil from the first pressure chamber 6 in the promoted second pressure chamber 7, the cylinder 5 moves up the piston rod 2 down. With reverse direction of rotation Pump 8 is hydraulic oil from the second pressure chamber 7 in the first Pressure chamber 6 promoted so that the cylinder 5 on the Piston rod 2 moved upwards.
- the pump 9 and the motor 12 are by means of suitable fastening means 13 connected to the cylinder 5.
- Pump 9 together with hydraulic lines 8, 10 and motor 12 can within a housing 14 connected to the cylinder 5 be arranged, which also serve as sound insulation can. This ensures that piston rod 2 with piston 4, Cylinder 5 with its pressure chambers 6, 7, pump 9 with motor 12 and the associated hydraulic lines 8, 10 a factory form pre-assembled unit, so on the construction site, on the the elevator system is to be built, no work on the Hydraulic system are necessary. So that the assembly costs reduced and technical problems when filling the Avoid hydraulic system or its ventilation.
- FIG. 2 is a diagram of an elevator system with a Cabin 20 shown.
- the transmission of the movement of the cylinder 5 relative to the piston rod 2 on the cabin 20 takes place by means of of a rope 21.
- This rope 21 is in the example shown with its one end on parts 1 of the wall of the elevator shaft attached, with its other end to the cabin 20. In between the rope is guided over pulleys 22, 23.
- a first one Deflection roller 22 is attached to the cylinder 5. It is functional a loose roll.
- Two further deflection rollers 23 are through suitable means 3 with parts 1 of the wall of the elevator shaft connected, thus represent fixed roles.
- Such a well-known The arrangement is characterized in that the path of the cabin 20 is twice as large as the path of the cylinder 5 on the Piston rod 2.
- the size of the counterweight to be defined differently. It is essential that it is known to be advantageous, the total mass of the Counterweight acting parts with the weight of the cabin 20 half nominal load. This results in rope and Deflection pulley arrangement another dimensioning rule. Depending on Weight of pump 9 and motor 12 is therefore the size of the Balance weight 15 to dimension.
- FIG. 3 is a horizontal partial section through the Piston rod 2 and the cylinder 5 shown.
- the cylinder 5 On the one hand of the cylinder 5 is the unit according to the aforementioned arranged from pump 9 and motor 12 and with corresponding Fasteners 13 attached.
- the balance weight 15 On the opposite On the side of the cylinder 5, the balance weight 15 is arranged that the center of gravity of the cylinder 5 together with attached parts in the longitudinal axis of the piston rod 2.
- the cylinder 5 together Pump 9, motor 12 and balance weight 15 around the axis of the Carry out a certain rotational movement of piston rod 2.
- the guide 31 connected to parts 1 of the building intervenes.
- Elevator cabs are usually guided on a frame. at the implementation of the invention, it is advantageous to the entire aforementioned unit consisting of piston rod 2 with piston 4, cylinder 5 with its pressure rooms 6, 7, pump 9 with motor 12 and the associated hydraulic lines 8, 10 with this frame prefabricated at the factory.
- the guide rollers 23 and the Guide 31 can be attached to this frame in the manufacturing plant become. This will continue the assembly on site simplified.
- the cabin 20 can also be factory-fitted to the frame be attached.
