Definitions

  • the present invention relates to an elevator comprising an elevator car travelling in an elevator shaft, at least one vertical guide rail, a control unit for controlling the elevator, a machine for driving the elevator car and a means for transmitting the driving power from the machine to the elevator car, the driving machine and the control unit of the elevator being placed in a space provided beside the elevator shaft (1) below the lowest landing.
  • FI-patent publication 50864 describes a solution in which the rope suspension is so implemented that the driving machine can be placed lower down.
  • the lifting rope runs from the elevator car to the machine via a diverting pulley placed at the top end of a guide rail, said pulley being so mounted on the guide rail that the latter receives the load imposed on the pulley by the lifting rope.
  • the elevator car and its load are supported by one or more guide rails.
  • the object of the present invention is to achieve a space-saving solution that is also easy to maintain.
  • the invention is characterized in that the space where the driving machine and the control unit of the elevator are placed is covered at the top by an openable cover structure.
  • a preferred embodiment of the invention is characterized in that the cover structure forms a safety fence when opened.
  • Another preferred embodiment of the invention is characterized in that the space together with its equipment is manufactured in factory and transported and installed as a complete unit.
  • the invention offers many advantages as compared to previously known techniques. One of them is that no separate machine room is required.
  • the fact that the machine space is placed in conjunction with the bottom well off the elevator shaft reduces the costs as compared to the building of a separate machine room.
  • the machine space is of a size that allows it to be manufactured in factory and transported and installed as a complete unit. An ordinary machine room is too large to be produced in this way.
  • the machine space can be so placed that the noise of the machine will cause only minimal disturbance to the people living in the building.
  • the electricity supply cables required are shorter than in the case of a machine placed on top of the shaft. If a traction sheave machine is used, the angle of contact between the rope and the traction sheave is over 180°. In traditional elevator suspension, this angle is under 180°. The required friction force is therefore achieved with a smaller undercut of the groove, which means that the ropes will last longer.
  • the machine space of the elevator is more easily accessible for maintenance. It also makes it easier to enter the space under the car during
  • Fig. 1 shows a lateral view of a solution representing an embodiment of the invention.
  • Fig. 2 shows a top view of the solution of fig. 1 in a larger scale.
  • Fig. 3 shows a lateral view of a solution representing an another embodiment of the invention.
  • Fig. 4 shows a top view of the solution of fig. 3 in a larger scale.
  • Fig. 5 shows yet another embodiment of the invention in lateral view.
  • Fig. 1 shows an elevator shaft 1 accommodating a car 2 and a counterweight 3.
  • the elevator car is driven by means of a lifting rope (or lifting ropes) 7 by a driving machine 4, which in this embodiment consists of a motor 5, a traction sheave 6 and a power transmission 23 placed between them (fig.2).
  • the driving machine is placed in a space 8 provided for it beside the elevator shaft 1 below the lowest landing.
  • the lifting rope runs from the traction sheave 6 to a diverting pulley 9 placed below the elevator car and then up over a diverting pulley 10 at the top of the elevator shaft, then down again round a diverting pulley 11 and further round another diverting pulley 12 (fig.
  • the machine space 8 is provided with a cover 25, which is turnably mounted with a hinge 24 in the top part of the space.
  • the cover is shown in a partly open position. If necessary, the cover may consist of more than one wicket, e.g. three wickets opening in different directions.
  • FIGS 3 and 4 present another embodiment of the invention, in which the elevator is driven by a drum machine.
  • the machine 4 is again placed in a space provided for it beside the elevator shaft below the lowest landing.
  • the machine consists of a motor 5 and a drum 17 rotated by it, the lifting rope(s) being attached to the drum.
  • the power transmission between the motor and the drum is not shown, but it can be implemented in any conventional way.
  • the rope runs from the drum 17 to a diverting pulley 18 below the elevator car 2 and then round another diverting pulley 19 at the top of the shaft, from where it returns down to a diverting pulley 11 mounted on the elevator car.
  • Fig. 3 does not show the cover structure, but it may be e.g. as presented in fig. 1. Note that diverting pulleys 18, 11 and 12 in fig. 4 are presented somewhat misleadingly, for, as shown in fig. 3, they are located below the elevator car, not above it as suggested by fig. 4. However, the aim has been to show the diverting pulleys in a complete form to give a clearer idea of the rope suspension arrangements.
  • Fig. 5 illustrates an embodiment in which the invention is applied to a hydraulic elevator.
  • the arrangement comprises a driving machine 4 consisting of a motor and a hydraulic unit known in themsleves.
  • the hydraulic unit is connected to the oil space of a hydraulic cylinder 21 by an oil pipe 20.
  • the piston 22 moving in the cylinder is directly attached to the elevator car 2.
  • a preferred embodiment is so implemented that the cover structure 25 forms a safety fence when opened.
  • the machine space 8 and the equipment belonging to it, such as the elevator machine 4 and its control unit, can be manufactured in factory and installed as a single package. In this case it is possible to mount the package in place e.g. by encasing it in concrete.
  • the machine space is placed on the front side of the elevator car, i.e. on that side where the elevator doors are located, where generally there is more free space available than elsewhere.
  • the machine space can just as well be placed on any other side of the shaft if necessary.
  • a hydraulic elevator need not necessarily be of the direct-acting type as illustrated by fig. 5, but indirect-acting hydraulic elevators are also possible.
