Definitions

  • the invention relates to an elevator system for the vertical transport of people and / or loads in a car, in which the drive with gear is arranged next to the elevator shaft.
  • Ropes are used as suspension elements in elevator systems with mechanical drives.
  • the machine room for the elevator is located above the elevator shaft.
  • the machine room can be arranged next to the elevator shaft.
  • the car is raised directly or indirectly by means of oil pressure via a reciprocating piston.
  • the hydraulic oil is supplied to the lifting cylinder of the elevator via pressure lines from an oil pressure pump arranged next to the elevator shaft.
  • a hydraulically operated elevator system however, has serious disadvantages, which are that oil can leak and collect in the elevator pit. This increases the risk of fire. If the sealing of the elevator pit is damaged, the oil penetrates into the ground and causes pollution.
  • hydraulically operated elevator systems are considerably more complex than a mechanically operated elevator in terms of monitoring their function and safety. For example, it is necessary to monitor the position of the car on each floor and to pump it up again when it drops, even when the basket is at a standstill, because hydraulic valves are leaking and the car is sagging. It is also necessary to provide pipe rupture protection in hydraulic systems that will function when the oil pressure drops.
  • a hydraulic elevator system usually requires an electrical connection value which is about three times as high as a comparable mechanical elevator system.
  • mechani elevator systems that use ropes as a suspension element the weight of the car and half the payload is balanced by a counterweight.
  • an elevator installation of the generic type is characterized in that chains, for example roller or leaf chains, are used as suspension means for the elevator car, which chains are arranged by a deflection and drive wheel 4 on the side of the elevator shaft Drive or gearbox are guided on the one hand via upper deflection rollers in the elevator shaft to the car, and on the other hand via fixed deflection rollers or deflection rollers on the elevator car to a chain tensioning device. Since the use of chains for driving the car and for connection to the tensioning device ensures a smooth run over the drive wheel and deflection rollers, the machine room can be arranged next to the shaft of the elevator system, so that the problems with regard to the height of the elevator shaft are eliminated.
  • chains for example roller or leaf chains
  • the energy requirement of such a drive is approximately 1/3 of the energy requirement of a hydraulic system. Since there is a requirement in mechanical elevator systems with rope operation that the diameter of rope deflection rollers is 40 times the rope diameter, for example with a rope diameter of 12 mm a deflection roller already has a diameter of about 50 cm. A reduction in the height of the shaft cannot therefore be avoided in such cable-operated elevator systems, even if the machine room is arranged next to the shaft.
  • Chain deflection rollers can be arranged in the elevator shaft and, for example, also under the car.
  • a chain hoist 18 leads from the drive wheel 4 via an upper deflecting roller 6 vertically in the shaft 1 to deflecting rollers 8 in the uppermost part of the shaft 1. It is a chain hoist which consists of two chains guided in parallel.
  • the deflection rollers 8 are assigned to the two opposite sides of the car 2 and from there the chain hoist 18 leads to suspension points 20 on the car.
  • the chain hoist 18 wraps around the drive wheel 4 and is guided from there as a chain hoist 19 to a lower deflection roller 5 in the shaft 1 down to a deflection roller 7 arranged above the bottom of the shaft and from there again vertically upwards.
  • the chain hoist 19 is fastened to the car 2 by a tension spring 12 in the vicinity of the floor of the car.
  • the car 2 is suspended from two parallel chain hoists 18 in the same way as in the previously described embodiment.
  • the chain hoist 19, which continues the chain hoist 18 beyond the drive wheel 4, is guided vertically upward in the shaft via the lower deflecting roller 5 to an upper deflecting roller 15, which is arranged directly below the upper deflecting rollers 8 of the chain hoist 18. From there, the chain hoist 19 is guided downwards and a weight 13 is attached to it as a chain tensioning device.
  • the machine room 3 is arranged next to the shaft 1 as described above.
  • a chain hoist 18 leads from the drive wheel 4 via an upper deflection roller 6 into the shaft and from there vertically upwards to deflection rollers 8 which are arranged directly below the upper end of the shaft. From there, the chain hoist 18 leads to deflection rollers 16, which are arranged above the roof of the car 2 on opposite sides, the chain hoist 18 is thus guided parallel to the roof between these two deflection rollers 16.
  • the chain hoist 18 is fixed at a fixed point 11 in the shaft.
  • the car 2 is suspended from the pulley 18 on the chain hoist 18 in the same way as in the previously described exemplary embodiment.
  • the chain hoist 19 is brought up again from the deflection roller 15 on the weight 13 to a fixed point 10, which is located directly next to the upper deflection roller 15 of the chain hoist 19.
  • the difference in the suspension of the car 2 is that the chain hoist 18 is guided over upper deflection rollers 14 and then over deflection rollers 17 which are arranged under the floor of the car and on opposite sides, so that the chain hoist 18 is guided parallel to the bottom of the car 2 to this.
  • the chain hoist 18 is then fixed at a fixed point 11 in the shaft 1.
  • FIG. 6 differs from the embodiment of FIG. 5 only in the design of the chain tensioning device.
  • the car 2 is suspended in the same way on chain guide rollers 17 arranged under its floor.
  • the chain hoist 18 leading to the elevator car 2 is continued via the drive wheel 4 as a chain hoist 19 to a deflecting roller 5, on which the chain hoist 19 is guided vertically in the shaft to an upper deflecting roller 15 which is mounted below the deflecting rollers 14 in the shaft.
  • the chain hoist 19 leads from the deflection roller 15 down the shaft to a deflection roller 15, on which the weight 13 hangs as a chain tensioning device. From the deflection roller 15 of the weight, the chain hoist 19 leads vertically up again in the shaft to a fixed point 10, which is arranged directly next to the upper deflection roller 15 of the chain hoist 19 in the shaft.
