Definitions

  • the present invention relates to an elevator arrangement as defined in the preamble of claim 1.
  • elevators are needed before the building has been finished. Either the elevators are needed for construction time use or the lower floors are completed before the rest, in which case the elevators serving them must be available for use. As the construction work is advancing, the elevator must be able to serve as many floors as possible.
  • jump elevators For construction time use, so-called jump elevators have been developed, in which the hoisting height of the elevator is increased gradually as the construction work advances.
  • the elevator machine room is moved to an upper level and the length of the elevator rope is increased correspondingly.
  • a general requirement concerning elevators is that the elevator should be usable in its entirety and with all its properties. Therefore, all other components depending on the hoisting height, such as the car cables, compensating ropes, overspeed governors and the electrification and electric cables in the hoistway should also be extended through the whole length of the finished hoistway.
  • FIG. 3 of JP-A-07/97157 shows in detail the releasble anchorage 17 employed in the elevator arrangement according to figure 1; by successively attaching the end of the elevator rope to anchorages spaced upwardly along the elevator shaft, the effective length of rope may be increased whenever the rise of the building increases.
  • a winding drum 21 selectively lockable against rotation, combines the functions of rope store and of detent means and is situated at the bottom of, and outside the elevator shaft.
  • the object of the present invention is to achieve an economic elevator arrangement for construction time use which, with the progress of construction work, can be easily lifted to a higher working level and which is also suited for use as the regular elevator of the building.
  • the invention is characterized by the features presented in the characterization part of claim 1.
  • Other preferred embodiments of the invention are defined in the subclaims.
  • detent means for the elevator ropes are disposed substantially proximate the machine room deck in order to selectively secure the elevator ropes against movements. Further the elevator ropes extend beyond the detent means to a rope supply located outside the hoistway and below the machine room deck.
  • the solution of the invention allows easy provision of the additional rope length needed as the height of the building increases.
  • all components of the elevator are always immediately available for use without complicated adjustments or settings.
  • Those portions of the hoist rope and compensating rope which are not yet in use can be freely disposed in a suitable place, even in a space outside the building.
  • the equipment in the machine room used during construction constitutes the elevator machine room of the finished building as far as applicable.
  • Fig. 1 illustrates the elevator arrangement of the invention.
  • the drive machine 18 consists of an elevator motor, possibly provided with a gear, and a traction sheave driven by it.
  • An elevator rope 4 has been fitted to run over the traction sheave and attached by one end to the car 2 or car frame.
  • the elevator rope runs over a diverting pulley 20 and via a diverting pulley 54 mounted in the upper part of the counterweight 56 back to the machine room deck 22, from where the elevator rope 4 is further passed over a diverting pulley 55 and fixed substantially at the level of the machine room deck 22 by means of a clamp 24 fastened to the hoistway or building structures.
  • the elevator car is implemented using a 1:1 suspension ratio, so the circumferential velocity of the traction sheave corresponds to the velocity of the elevator car.
  • the counterweight is suspended with a ratio of 1:2, so the velocity of the counterweight equals half the circumferential velocity of the traction sheave.
  • a compensating rope 10 Fixed in a known manner to the bottom of the elevator car 2 is a compensating rope 10, which is passed via a diverting pulley 12 in the lower part of the hoistway and via a diverting pulley 58 connected to the lower end of the counterweight 56 to the bottom of the hoistway, where it is fastened to a rope clamp 26.
  • the compensating rope as well as the elevator rope are suspended with a ratio of 1:1 on the side of the elevator car and with a ratio of 1:2 on the side of the counterweight.
  • the elevator works in the normal manner.
  • the rope supply is preferably located in the lower part of the building at or below the level of the first temporary position of the machine room deck.
  • the extra portion 14 of the compensating rope behind clamp 26 is stored on rope reels in rope supply 16.
  • the overspeed governor rope 32 is attached by one end to the elevator car and passed via a diverting pulley 35 in the lower part of the hoistway to the overspeed governor wheel 34.
  • the overspeed governor rope 32 is fastened to a clamp 36 on the top of the car and the free rope portion 38 is stored in an overspeed governor rope supply 40 placed on the top 42 of the car.
  • Deck 48 is connected to deck 22 in such a way that both decks can be raised together as the construction work advances.
  • the supply of electricity to the elevator car and the control of the car equipment are implemented in a manner known in itself by using a car cable 43, which is connected to the elevator car 2 and to the elevator control unit 50.
  • a car cable supply 44 is provided on the machine room deck 22.
  • a hoistway cable supply 46 for hoistway wiring 45 is likewise provided on the machine room deck 22.
  • Fig. 2 presents another example of an embodiment of the invention, in which the compensating system is implemented using chains 60.
  • the compensating chain 60 is extended with the required length of additional chain.
  • the arrangement in Fig. 2 corresponds to the solution illustrated in Fig. 1 and corresponding parts are indicated by the same reference numbers as in Fig. 1.
  • the elevator machine room and its supporting beams are raised somewhat by means of a crane or construction hoist (not shown), whereupon the supporting means of the machine room structure can be released.
  • the machine room is raised to the next machine room level by means of a hoist or by some other applicable hoisting method.
  • the hoist ropes and compensating ropes run freely from the rope reels of the rope supplies.
  • a length of overspeed governor rope is spooled off from the overspeed governor rope reel on the top of the elevator car.
  • lengths of car and hoistway cable corresponding to the lift are released from the car cable and hoistway cable reels on the machine room deck.
  • the supporting means of the machine room deck are activated and the machine room supporting beams are reliably secured to the building.
  • the overspeed governor rope is fixed to the top of the car.
  • the elevator car is hoisted to the highest level by means of a hoist or crane, whereupon the hoist ropes and compensating ropes are secured, tightened to the right tension and locked in place by means of rope clamps.
  • the counterweight is released and the car and hoistway cables are secured and connected to the control panel. After this, the elevator is ready to serve the new floors.
  • the compensating chain is extended before the machine room deck is hoisted to the new working level.
  • the construction time machine room together with the hoisting machine and other machine room equipment can be left permanently in place, so that they form a corresponding part of the machine room.
  • the rope supplies and other equipment used temporarily during construction are now unnecessary and they are naturally removed.
