Lifting action to counterweight 120 is illustrated below.
Drive when using motor 105 to rotate by the control of controller (not shown), through driving pulley 106, toothed belt 108, follow-up pulley 107, sheave shaft 121 makes hauling block 103 rotations.Like this, hauling block 103 moves steel rope 104 by friction force, and counterweight 120 integral body rise or descend according to the transport direction of steel rope 104.Like this, the length variations of the steel rope 104 on the counterweight 120 is suspended on the cage (not shown) lifting on steel rope 104 the opposing party.At this moment, anglec of rotation detector 112 is learnt the anglec of rotation of driving pulley by the anglec of rotation that detects roller 111.Because the reduction ratio of the reduction train that the diameter of roller 111 and driving pulley 106, follow-up pulley 107 and driving pulley 106 constitute and the diameter of hauling block 103 are known, thereby according to the anglec of rotation of roller 111, learn the amount of batching of steel rope 104, can detect the position of cage.In addition, the time of the anglec of rotation by calculating roller 111 changes, and also can calculate the anglec of rotation that drives with motor 105, to be used to drive the Spin Control with motor 105.
The following describes drg.
Cage rest in regulation stop layer (not shown) after, drg 207 action, restriction courtyard pulley 206 rotation, the fixedly winding positions of steel rope 104.Like this, also limit the position of cage 201 and counterweight 120.Afterwards,, when opening power circuit side derailing switch 505 once more, close regenerative circuit side derailing switch 506, drive with short circuit between the coil winding of motor 105 by controller 504.In this state, for example make rotation drive the external force action rotor of the rotor (not shown) of using motor 105, then the magnetic flux change between magneto-electric machine 508 in-to-in permanent magnet (not shown)s and the winding coil portion (not shown) produces induction on winding.The electric current that produces because of induction flows through winding, but because the resistance 507 between winding is short-circuited, this electric energy becomes heat energy and disperses loss.For this reason, on winding, produce reverse induction, generate the electromagnetic force that overcomes aforementioned magnetic flux change, the rotational force of the rotor (not shown) that creates antagonism rotation, the result has limited the rotor rotation.
Below, the effect of anglec of rotation detector 112 and roller 111 is described.
The signal that the utilization of controller (not shown) drives with the anglec of rotation detector 112 of motor 105 is rotated control.At this moment, when abnormal condition such as generation cut-out toothed belt, can make the rotating speed of driving pulley different with the rotating speed of anglec of rotation detector 112.At this, at velocity contrast one regularly, it is unusual that controller is judged above-mentioned belt-driving, opens power circuit side derailing switch 505, stops to power to driving with motor 105, and closes regenerative circuit side derailing switch 506, makes to drive with short circuit between the winding of motor 105.Effect afterwards is, and is illustrated at the 1st example, drives the rotor (not shown) braking force with motor 105, makes it stall.Simultaneously, the drg 207 that 504 pairs of controllers are disposed on the courtyard pulley 206 of hoistway courtyard portion sends instruction, makes 206 stalls of courtyard pulley, the improper lifting that stops cage and counterweight.Adopt this example, even under the abnormal condition that drive belt cuts off, cage apace also can stop.
Like this, above-mentioned lift appliance can be equipped with winding plant in the counterweight 120 flat, that the space is less originally.Because of on the counterweight 120 reductor being housed, make to drive and reverse lessly with required on the motor 105, can improve revolution, drive 105 miniaturizations of usefulness motor thereby can make.In addition, use motor 105 different with the rotating shaft of hauling block 103 because drive, by making bearing difference separately, the weight of hauling block 103 there is no need to be born by motor bearings.For this reason, driving also can be less with the motor bearings part, makes to drive and uses the motor miniaturization.Have again,, be difficult to take place that the gear type reductor caused is differential or vibrate so many problems, improved the riding sensation of cage by using toothed belt 108.
In addition, because drg does not leave counterweight inside in, in counterweight inside, the space that drives with the motor part becomes big.In addition, there is no need to make drg if can leave the inner miniaturization like that of counterweight in.
Particularly, though have a power failure or improper situation under, when promptly stopping cage, because of resistance, rotation that can the electric braking rotor, and can stop to drive with the inertia due to the inertia such as motor or hauling block and rotate.Therefore, can avoid steel rope or belt to produce excess tension, can protect service machine.
In addition, even under the abnormal condition that toothed belt cuts off, the car of also can judging fast and stop.
In addition, the reductor part of above-mentioned toothed belt and band tooth pulley formation can be the transmission machinery that is made of chain and sprocket wheel.
Fig. 3 is the sectional view of signal that the cover cap structure of counterweight is shown.
Being covered by noise control lid 302 on every side of counterweight 120 encases inner component parts.Stream line pattern lid 301a is housed on the top of counterweight 120, stream line pattern lid 301b is housed in its underpart.Stream line pattern lid 301a, 301b upper end, lower surface separately is curve form, is installed in well enclosure 306 sides with aforementioned curved face part.Sound absorption materials 303a, 303b in filling in the counterweight 120 volume inside gaps of formation noise control lid 302 and stream line pattern lid 301a, 301b.In addition, as the hoistway side of counterweight 120 back side portions and drive, radiator fan 305 is housed with near the motor 105.It is a plurality of grooves that pectination, vertical direction distribute that radiator fan 305 is provided with horizontal section.
The effect of said structure is as follows.At first,, drive the noise that is produced with motor 105 and reductor 127 and be enclosed in counterweight inside, prevent to leak by noise control lid 302 and stream line pattern lid 301a, 301b.Have, the noise that is taken place also can be absorbed by sound absorption materials 303a, 303b again.
In a single day counterweight 120 rises, and the air on counterweight 120 tops direction shown in arrow among Fig. 3 flows, and 301a flows between the back side and well enclosure 306 of counterweight 120 along the stream line pattern lid.At this moment, the curved face part of air longshore current line style lid 301a is quickened, and increases flow velocity.So air drives and uses near the temperature of motor to descend by heat absorption when the radiator fan 305, cooling drives uses motor 105.Same with above-mentioned principle when counterweight 120 descends, the air that flow velocity increases prevents to drive the temperature rising with motor 105 by radiator fan 305 heat absorptions.
Like this, adopt above-mentioned example, can prevent that noise from generating, and can realize the device of stable calmness.
Have, the driving along with driving with motor can absorb the heat energy that is generated effectively again, can prevent to drive the rising with motor 105 temperature.
The view of Fig. 4-Fig. 6 illustrates counterweight towards the solid timer-operated fixing means of guide rail.
