Definitions
- the invention relates to a gearless cable lift with one of several parallel Steel carrying cables Double-wrapped traction sheave drive with counter-pulley, a car, Guide rails for the car and a counterweight, in particular for a machine room-less. Installation of the elevator machine.
- the car and the counterweight are connected to each other via the suspension element rope connected.
- the counterweight is equal to the net weight of the car and a part, mostlycns half, the payload and half the net mass of leading to the car Suspension cable off.
- the traction sheave as a driving ring can be executed.
- electric motors are used.
- traction sheave and propulsion engine including its energetic and control part are essential Components of a gearless elevator machine.
- Gearless lift machines are extremely quiet and small and inexpensive. They are more advantageous than Elevator machines with gearbox. For them, no environmentally hazardous gear oil is needed and the elimination of the transmission improves the efficiency.
- the elevator machine is in a separate machine room or directly in the vehicle shaft Installed. In the latter case, it may be in the upper or lower part of the Shaft, laterally in the space for the counterweight or directly on or under the Car installed.
- the car payload and more Conditions, such as head or conveyor speed have different Supporting rope guides developed.
- the single suspension the suspension cable is coming from the car coming over the traction sheave permanently installed in the shaft head or in the machine room above it led to the counterweight.
- suspension cable guides in multiple suspensions, the use of loose roles at the same time a specific ratio from rope to car speed.
- the rope drive with a loose roller on the car and a loose roller on the counterweight executed the torque of the drive motor decreases in half double speed. The machine is smaller and can be easier in the elevator shaft to install.
- An arrangement with double wrap by two or more parallel support cables is For example, described in DE 36 34 859 A1. Moving from the car to the counterweight extending ropes are twice around the traction sheave and between them Loop once wrapped around a pulley, with the contact angle between the traction sheave and the suspension cables in both loops around the traction sheave 180 ° exceeds.
- a variant with double wrap and two deflection plates is shown in FIG. 2c of EP 0 578 237 A1.
- a machine roomless arrangement with double wrap around the traction sheave is in WO 99/43595.
- the suspension element runs from an upper side stop Coming, twice at the traction sheave and counter-disc, both at the bottom of the Racks are fixed, in the further back up, where it deflects on a fixed role and finally a loose roll on the counterweight to a second upper rope stop.
- Traction sheave and counter-disc have such a distance from each other that a Pulley on the car floor becomes unnecessary.
- As a support means are two parallel flat strands provided, as specified for example in WO 99/43885. Further flat strands are shown for example in WO 98/29327.
- small pulley diameters are in elevator construction particularly advantageous because they allow a compact design of the drive motor.
- small traction sheaves have the disadvantage that the suspension rope is more stressed and the rope life is thereby reduced.
- Pulley diameter of at least 40 times the shroud diameter used wherein the reduction of the carrier rope diameter through the use of the above described Flat strands is achieved as drive cables with a particularly small diameter.
- the JP 07-117957 A discloses an elevator in which a plurality of parallel support cables Double wrap a traction sheave drive with counter pulley.
- the leadership of Ropes are in semicircular drive grooves.
- EP 0 672 781 A relates to elevators using synthetic fiber ropes, to allow a greater number of bending changes.
- the invention is based on the object, a gearless cable lift with double Wrap to develop so that the disadvantages of the flat strands are avoided and the elevator has a compact and inexpensive construction.
- the ratio of the pulley diameter to the nominal diameter of the suspension ropes is less than 40.
- a ratio of essentially 30 has proved to be very beneficial.
- small pulley diameter allows, creating a compact and inexpensive construction of the drive motor is guaranteed.
- the reduced rope life, which decreased by one Drive pulley diameter results in accordance with the invention by the use of Semicircular drive grooves avoided, in which the steel carrying ropes run. True, by the use of half-round grooves reduces the drive capacity of the drive pulley, this will however compensated by the use of a double wrap.
- the ropes are running in undercutless drive grooves, but also driving grooves with a low undercut, preferably from 1-3 mm. Such a small undercut can have a positive effect on the running properties.
- the drive torque can be greatly reduced in the cable according to the invention, which also makes the prime mover smaller.
- the suspension cables do not experience such an extreme bending radius and extreme rolling speeds like the flat strands on traction sheaves with a diameter of ⁇ 100 mm.
- the thin support cables are in the the carrier rope diameter exactly adapted half-round grooves the traction sheave very well, causing deformations of the rope and transverse pressures be avoided and the surface pressure is reduced.
- the suspension cables thereby reach a high resting time. Due to the circular cross-section of the suspension cables "find"
- the ropes always in the size exactly matched half-round grooves of the drive wheel. Consequently, they have no tendency to vibrate or unequal Strain to wander out of bed. In addition, a not to be underestimated occurs Noise reduction on.
- the invention is thus based on the finding that by a combination of a double wrap of the drive rope with the guide in semicircular drive grooves, the ratio Drive pulley diameter can be reduced to nominal diameter of the suspension cables, thereby smaller Tragseil tipmesser and thus a cheaper construction of the cable lift is ensured with undiminished long rope life.
- a particularly preferred embodiment of the invention are particularly thin Supporting cables with a nominal diameter between 5 to 7 mm, in particular of ⁇ 6 mm used.
- the lubrication and cleaning is thinner Ropes more effective than thicker ropes.
- the ropes are always oversized be what makes the elevator more expensive
- a known rope drive with double wrap is shown in more detail.
- traction sheave with a nominal diameter 240 mm even those with a small nominal diameter can be used.
- the nominal diameter can only be 180 mm, which is a ratio of pulley diameter to nominal diameter of the suspension cables of 30 corresponds.
- Fig. 1a only one of the 8 supporting cables of the supporting rope set 1 is shown for clarity.
- Traction sheave 2 and counter-disc 3 are shown arranged horizontally to each other. Likewise, they can also be arranged perpendicular to each other.
- the distance of Opposed disc 3 to the traction sheave 2 is chosen so that when horizontal disc arrangement in the shaft head of the supporting cable set 1 outside of the car sides, not shown in Fig. 1 passes. This eliminates an otherwise necessary additional deflection.
- the breaking strength of the suspension ropes depends decisively on the nominal diameter of the suspension ropes from the material and construction of a supporting rope.
- the most important technical data such as tensile strength the wires, calculated breaking force and determined breaking strength are determined by the manufacturer specified in a works certificate and serve the elevator construction for calculation the necessary number of suspension cables of the suspension cable set 1.
- the above information can therefore only be indicative, especially since a u.a. from the nominal rope speed and the cable guide dependent, high safety factor the result significantly affected.
- Fig. 2 is an example of a machine room-less installation of the traction sheave drive shown schematically in the shaft head.
- the shaft wall 5 bounds the free Shaft space. From above you can see the roof of the car 6.
- a deflection wheel 12 installed on the counterweight 11 wraps around and then to a second cable stop 13 runs upwards.
- the counterweight 11 and its deflection pulley 12 run laterally between the shaft wall 5 and a side wall of the car 6th Die Cable guide, with a 2: 1 gear ratio of the rope speed at the traction sheave 2 is reached to the car speed at half the driving torque, comes the use of a small, faster-running drive motor 7 with small traction sheave. 2 and thin suspension cables very contrary and is shown schematically again separately.
- the attachment means for the traction sheave drive in the shaft head are also omitted like the side guide rails for the car and other components of a car usual cable lift.
- Fig. 3 shows the installation of a traction sheave drive on a shaft wall 5.
- the set of suspension ropes 1 runs from a first Rope stop 10 on the pulleys 8, 9 to the traction sheave 3, 2, wraps around the driven by the drive motor 7 drive pulley 2 twice, runs to the guide roller 12, on the the counterweight 11 hangs, and ultimately runs to the second cable stop 13.
- the pulleys 8, 9 can both on the roof of the car 6 and under the ground be fastened to the car 6. Both variants are shown schematically.
- the described Support rope guide realizes a 2: 1 suspension.
- the traction sheave drive is permanently installed at the top, bottom or side of the shaft, it will become conveniently attached to the elevator frame.
- the traction sheave drive is installed at the bottom of the elevator car 6.
- the set of suspension ropes 1 runs from the first cable stop 10 to the counter-disc 3 and the traction sheave. 2 around, which are both attached to the bottom of the car 6, in the further up, over a deflection roller 14, the deflection roller 12 wraps around the counterweight and is ultimately with attached to the second end of the second cable stop 13. It will turn one 2: 1 suspension realized.
- the traction sheave drive is installed on the roof of the elevator car 6.
- the Cable guide corresponds to the cable guide according to Fig. 4.
- Crucial for the choice of installation the traction sheave drive on the car floor or on the car roof are ultimately the local conditions in the shaft and the possibilities for a disability Maintenance of the traction sheave drive.
- the traction sheave drive is installed on the car 6, the car frame or the Car main carrier expediently supplemented by appropriate holding means.
- the car suspension can be in the ratio 1: 1, 2: 1 or even 4: 1, depending on whether and how many loose rolls are used.
- suspension cables single-layer round rope ropes can be used, wherein the individual Round wires of carbon steel with a relatively high content of carbon of 0.4 % to 1% are drawn. But it can also be used multi-layer round strand ropes.
