Definitions

  • the present invention relates to a system in construction-time operation of an elevator as defined in the preamble of claim 1 and to a method as defined in the preamble of claim 10 for raising a machine room.
  • Elevators are either needed for operation during construction or the lower floors are finished earlier than the rest, in which case the elevators serving them have to be available for use. With the progress of construction work, the elevator has to be able to serve as high 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 in a stepwise manner as the construction work is progressing.
  • the elevator machine room is moved to a higher floor and the length of the hoisting rope in use is increased accordingly. It is generally required that the elevator should be available for use in its entirety and with all its properties. Therefore, other components depending on the hoisting height, such as car cables, compensating ropes, overspeed governors and hoistway electrification and hoistway cables should be extended over the entire length of the finished hoistway.
  • the object of the present invention is to achieve an advantageous elevator for use during construction time which can be easily lifted to a higher operation level as the construction work is progressing and which is also applicable for use as a normal elevator in the finished building.
  • the system of the invention is characterized by the features presented in the characterization part of claim 1.
  • the method of the invention is characterized by the features presented in claim 10.
  • Other preferred embodiments of the invention are defined in the subclaims.
  • the increase of rope length required as the height of the building is increasing is easy to implement. All components of the elevator are always immediately available for use after a move to a new operation level, without requiring any complicated adjustments or settings. The portion of the hoisting rope that is not yet in use is carried along on the car and no external storage space is needed for it. Thus, there is no need to provide for the elevator a temporary storage which would be an impediment to other utilization of the building. The components of the elevator are directly usable as such after the elevator and the building have reached their final height.
  • the compensating cable of the elevator is of an extendable design, being made of e.g. chain links, in which case an appropriate number of links are added to the compensating cable when the elevator is to be lifted to the next level. If the final speed is higher than the maximum operating speed of the compensating cable, then the compensating cable of the finished elevator is replaced with compensating ropes, thus allowing the maximum speed of the elevator to be increased to its final value.
  • the elevator comprises rope supplies of compensating ropes below the car, permitting the elevator to be operated at maximum speed already during construction time.
  • FIG. 1 presents an elevator according to the invention
  • FIG. 2 presents another elevator according to the inven- tion.
  • Fig. 1 is diagrammatic representation of an elevator system, presenting the components significant with respect to the invention while other parts of the elevator are only indicated by reference.
  • Mounted in the up- per part of a completed hoistway 1 delimited by side walls 28 and 30 and a back wall 29 is a machine room 7 with an elevator drive machine 12 installed in it.
  • the machine room is supported by supporting elements 14 on the hoistway structures.
  • the drive machine 12 consists of an elevator motor, which may be provided with a gear, and a traction sheave 15 driven by it.
  • the hoisting rope 9 has been arranged to run over the traction sheave and its one end is fastened to the car 13 or car frame.
  • the elevator is provided with a rope reel frame 6 disposed on the top of the car 13 and having a number of hoisting rope reels 10 corresponding to the number of hoisting ropes.
  • the hoisting ropes 9 are passed from the rope reels 10 via a locking device 11 up to the traction sheave 15.
  • the clamping of the rope can in principle be implemented using a wedge grip in the same way as is used for fastening the end of the hoisting rope in a perma- nent installation.
  • a rope clamping means is fixed to the elevator car for use at least during construction time.
  • the hoisting rope runs over a diverting pulley 16 to the upper part of a counterweight 5, to which it is fastened.
  • the elevator car and counterweight are provided with guides which guide their movement along guide rails 3 mounted in the hoistway.
  • the elevator car and counterweight are suspended using a 1:1 suspension ration, so the circumferential speed of the traction sheave corresponds to the speed of the elevator car and counterweight.
  • Attached in a known manner to the car frame 4 is a compensating cable 8, whose other end is fastened to the lower part of the counterweight 5.
  • the compensating cable is composed of chain links .
  • a hoisting apparatus 2 Disposed above the hoistway 1 or on the upper edge of the hoistway is a hoisting apparatus 2 used to move the machine room 7 to the next machine room level after the building and hoistway have reached a corresponding height .
  • the rope of the overspeed governor is fastened by one end in a known manner to the car and passed over a diverting pulley in the lower part of the hoistway to the wheel of the overspeed governor.
  • the overspeed governor rope is fastened to a clamp on the top of the car and a rope portion is stored in the overspeed governor rope supply on the top of the car.
  • the upwards going rope is fastened to the safety gear activating lever e.g. by means of a lift bar, by means of which the rope clamp- ing is moved to the level of the car top.
  • Disposed on the machine room level or on another level near it is a space for a control panel and an elevator control unit.
  • this other level is connected to the machine room level so that both levels can be moved up together as the construction work is progressing.
  • the supply of electricity to the elevator car and the control of the car equipment are implemented in a manner known in itself using a car cable, which is attached to the elevator car 13 and correspondingly to the elevator control unit.
  • a car cable supply is provided on the machine room level, preferably in the machine room.
  • a hoistway cable supply is also provided on the machine room level.
  • a hoisting apparatus 2 is brought above the hoistway 1, and guide rails are mounted in the hoistway portion above the machine room and landing doors as well as landing signal devices are installed in the doorways in the upper part.
  • the machine room preferably slides along the car guide rails, guided by sliding guides.
  • the hoistway cables in the upper part of the hoistway are installed so that they are ready to be connected to the control panel in the machine room.
  • the car is driven onto the buffers, the counterweight being thus brought to a high position, and the counterweight is fastened with a chain to the machine room.
  • the counterweight is pref- erably fastened by means of e.g.
  • the counterweight is raised a little, whereupon, when the rope clamping device is released, the counterweight will remain at the desired height.
  • the rope clamping device is released, whereupon the ad- ditional rope portion can be reeled out from the reels of the rope supply.
  • the hoistway wiring is detached from the machine room, the clamps of the overspeed governor rope are loosened and a stretch of car cable is reeled out.
  • the compensating cable is disconnected from the car frame con- nected to the cable on the compensating cable reel.
  • the machine room level is hoisted by means of the hoisting device to the next operation level, a length of hoisting rope corresponding to the hoisting distance being reeled out from the rope reel, whereupon the hoisting rope is fastened with a clamp.
  • the compensating cable is being reeled out.
  • the overspeed governor rope is being reeled out from the overspeed governor rope reel on the top of the elevator car.
  • lengths of car cable and hoistway cable corresponding to the hoisting distance are released from the car cable and hoistway cable reels on the machine room level.
  • the supporting means of the machine room are activated and the supported by beams carrying the machine room are fixed in reliable manner to the building.
  • the overspeed governor rope and the hoisting ropes are fastened, tightened to the correct tension and clamped in position.
  • the counterweight is released, the compensating cable is cut off and the cable end is fastened to the bottom of the car, and the car and hoistway cables are connected to the control panel. An amount of mass is removed from the counterweight so that the changed car and rope load is taken into ac- count. After a test run, the elevator is ready to serve the new floors.
  • Fig. 2 presents another example of an embodiment according to the invention, in which the compensating system is implemented using a compensating rope 30. Where applicable, the same reference numbers as in Fig. 1 are also used in Fig. 2.
  • the compensating ropes are placed on reels 32 constituting a compensating rope supply, placed under the elevator car. In the car, the compensating ropes are fastened with a clamp 34 placed just below the reels 32.
  • the compensating rope 30 runs around tension weight diverting pulleys 36 and 38 to the counterweight .
  • the compensating rope is extended by loosening the clamps 34 and reeling out a length of rope 30 corresponding to the hoisting distance.
  • the hoisting of the machine room is performed in a manner corresponding to the case illustrated by Fig. 1.
  • the rope supply for the compensating rope or the compensating cable supply can be placed on the counter- weight, in which case the mass of the counterweight will be changed, and so will the mass of the elevator car.
