Definitions

  • the present invention relates to an elevator, in particular a traction sheave elevator according to the preamble of claim 1 and the preamble of claim 6.
  • an elevator is known from EP-A-0631 966 already known.
  • traction sheave lifts have a car arranged in a hoistway and, moreover, an engine room in which the controller, engine, and other elevator components are located.
  • the ropes run from one side of the traction sheave down to the car and from the other side to the counterweight. So that the service personnel can also stay on the car roof during a journey for maintenance or installation work, a minimum safety space is prescribed for this purpose above the car roof, from the car roof in the uppermost car cage position up to the lower edge of components arranged above it or up to the Bay ceiling is enough.
  • elevators with lying outside the shaft engine room in the shaft head at most roller carrier for the pulleys of the supporting cables are arranged, which can also be arranged next to the claimed by the car shaft area.
  • the drive In lifts with engine in the shaft, the drive can be arranged in the upper or lower part of the lift shaft between the area required by the car during its travel movement and a wall of the lift shaft.
  • the disadvantage here is that because of the arrangement of the drive in the lift shaft not the entire cross-sectional area of the chute can be used for the car. The necessary with respect to a particular car larger dimensions of the lift shaft leads to higher overall costs for the elevator or space losses.
  • a further disadvantage is that the drive in a large-sized car can not exceed a certain size, e.g. To require recesses in the shaft wall.
  • the object of the present invention is therefore to provide a lift with elevator drive of conventional size arranged in the elevator shaft, without increasing the shaft head height in relation to elevators with an engine compartment lying outside of the lift shaft.
  • the total cost of the elevator can be reduced.
  • the drive in volume can be considerably larger and therefore more efficient than a narrow drive which can be attached only between the car and the shaft wall.
  • the car in the shaft is normal as in an elevator with engine room outside of the Tray movable, with a prescribed security space between the car roof and the ceiling of the shaft is guaranteed in the second area of the car roof.
  • the necessary height of the shaft is not higher than in conventional lifts with engine room above the shaft.
  • the drive comprises a motor, a traction sheave for a lift with counterweight and at least one deflection roller.
  • the invention according to claim 1 can also be used advantageously if instead of the entire drive only one or more pulleys are arranged above the car on roller carriers. It is possible, for example, to design the elevator with the machine below, and to arrange only the at least one deflection roller over the first area of the car roof. The area of the car roof below the pulley is locked in this case for a walk.
  • the drive is expediently held together with further elevator components, in particular cable end suspensions and a speed limiter, in a machine frame which is carried by the shaft walls, by guide rails of the elevator or by the shaft ceiling.
  • the individual elements of the drive can be pre-assembled in the machine frame in an advantageous manner, so that the drive thus mounted together with the machine frame is like a module in the lift shaft introduced. As a result, the assembly work on a construction site can be effectively reduced.
  • the first area of the car roof is not accessible by using mechanical and / or electrical securing means. This ensures that the drive is not switched on or is switched off when the service personnel enters the locked area of the car roof.
  • printing mats and / or infrared ray grid or motion sensors are arranged on the first area of the car roof, which can be activated in particular by entering the first area and prevent a drive or travel of the car.
  • a triggering device for a track boundary for a counterweight of the elevator is arranged in the region of the car roof. Such a triggering device can be triggered if necessary, e.g. by entering the restricted area. This further enhances security for service personnel.
  • an elevator with the features of claim 6 is proposed.
  • This solution also advantageously allows a reduction of the shaft height compared to conventional lifts.
  • the drive By arranging the drive at the height of the holder, namely the overall height of the holder and drive comprehensive assembly compared to conventional designs can be substantially reduced. This also makes it possible, with the same movability of the car to reduce the shaft height compared to the prior art and / or increase the drive if necessary.
  • the holder is arranged in the shaft head over a first area of the car roof, and the second area of the car roof adjacent to the first area ensures the safety distance between the car roof and the shaft ceiling prescribed above the car, the car roof being accessible or accessible and the accessibility or accessibility being ensured Accessibility is limited to the second area.
  • This embodiment essentially represents a combination of the two solutions according to the invention, and allows optimal utilization of the elevator shaft.
  • the holder is formed by a machine frame which surrounds the drive substantially laterally. This ensures a particularly space-saving mounting of the drive, which can be fixed in the shaft in a simple manner.
  • the drive can be made larger and more efficient in the contrary to previous solutions of drives in the shaft larger space.
  • the drive from below or above between the carrier of the machine frame can be introduced and fastened in a desired position. This makes it possible to pre-assemble the drive in the machine frame, so that the entire assembly can be modularly introduced into a hoistway.
  • a carrier of the machine frame rotatable or detachable, so that it can be brought into its supporting position after introduction of the drive in the machine frame.
  • the machine frame and / or the drive arranged in the machine frame are arranged horizontally obliquely with respect to the shaft walls. This makes it possible to ensure a direct, favorable for the suspension cable connection between a counterweight and the car.
  • the machine frame has recesses into which load-bearing areas of the drive engage, and / or support parts which project in the direction of the drive and around or in the bearing Drive parts engage, on.
  • additional pulleys, Seilendaufhfitungen and / or speed limiter of the elevator can be attached to the machine frame.
  • a pre-assembly is also possible with respect to these components, so that the installation effort or adjustment effort is reduced at the installation.
  • the machine frame further assembly aids, in particular eyelets for the attack of hoists and / or pulleys for ropes, which are used for pulling up guide rails in a scaffolding elevator assembly of the elevator.
  • a further mounting aid can be attached to the frame a hanger for a to be arranged in the slot control cabinet of the drive.
  • the drive is supported in the frame by means of two suspension plates, each of which has a vertical plate area for horizontally screwing on the drive and a horizontal plate area for isolated support on or in the frame.
  • machine frame can be fastened in shaft walls or in front of the shaft wall, on guide rails or on the shaft ceiling.
  • FIG. 1 shows a schematic representation of a cross section through the upper portion of an elevator 10 according to the invention.
  • the elevator 10 comprises a car arranged in a shaft 14 car 16 with a car roof 17.
  • the car 16 in its uppermost holding position and is shown only with its roof section
  • the lift shaft 14 of the elevator 10 is bounded by shaft walls 12 and a shaft ceiling 13.
  • a door opening bounded by a door reveal 22 is provided in the shaft wall 12 which is closed by means of a landing door 20 (cf. FIG. 2 ).
  • the car 16 is associated with a car door 26 which can be opened to open the passage between the car 16 and the floor together with the shaft door 20.
  • a drive for the car 16 to the vertical Verfahr in the passenger compartment 14 is arranged.
  • the drive comprises a drive machine 30, which is arranged in the shaft head above the elevator car 16. Further elements of the drive, in particular a traction sheave and suspension cables for connecting the engine 30 to the car 16 are not shown in detail for reasons of clarity.
  • FIG. 2 how out FIG. 2 it can be seen, the car 16 for vertical movement in the chute 14 along guide rails 28 which engage in arranged in a support frame 34 of the car 16 guides 29 guided.
  • the car 16 further acts in a conventional manner via the supporting cables not shown together with a counterweight 32.
  • the drive can also be equipped with a cable drum. Then the elevator comes off without counterweight.
  • a height h 1 is provided, which corresponds to the necessary and prescribed safety distance. Due to the arrangement of the drive machine 30 in the pit head, this height is, however, limited in sections to the height h 2 , so that in a region 17a of the car roof 17, the safety distance is not guaranteed.
  • a railing 18 is provided according to the invention for this reason, which delimits the safety space assigned to the area 17b from the area 17a of lower height. The railing 18 prevents service personnel from entering the area 17a of the car roof 17 while the elevator is moving. The stay of the service staff is thus limited to the area 17b.
  • electronic safety devices are provided. These may be, for example, pressure mats or pressure elements arranged in the region 17a or other electrical securing means which emit optical and / or acoustic signals upon entering this region 17a, which prompt them to leave this region, and / or block a method of the car 16.
  • pressure mats or pressure elements arranged in the region 17a or other electrical securing means which emit optical and / or acoustic signals upon entering this region 17a, which prompt them to leave this region, and / or block a method of the car 16.
  • tensioned nets or warning signs or diagonally formed roof surfaces can also be used.
