Especially, work as phaseThe building of answering existed and lift after be assembled in this building or for example in installment workMust interim lift be installed there during this time time, use the service lift of the above-mentioned type. Typical caseApplication example be the pylon of wind energy plant.
Such lifter apparatus and to this common driving mechanism for example from DE102010062Known in 774A1. Use in the prior art cable wire as suspension arrangement, described cable wire is in buildingSide is fixed on firmly some place. Personnel's holding mechanism or next by means of the winch drum of coiling cable wireMove up and down, or move up and down by means of so-called cable capstan winch, wherein said cable capstan winchBy means of traction sheave and being connected that cable wire formation power coordinates, but do not reel described cable, but formerGo up on the rope freely dangling and advance.
Although utilize the cable capstan winch of known type that the service lift generally speaking operation of moving is made usSatisfied, but in known system, still there is Improvement requirement. Like this at known cable capstan winchSituation under for example because the order of magnitude that acts on of traction sheave is to exist after duty cycle of 1,500Because the demand of heavy-duty ropes is changed in wearing and tearing. In addition, hard cable wire is due to its structural structureMake and also have the flexible characteristic of certain length, this can cause at service lift in service along perpendicularNogata to vibration. In addition the type of driver coordinating based on power, causes certain noise amplitude.
Summary of the invention
The present invention is therefore based on following object: propose a kind of service lift, described service liftImproved aspect above-mentioned will putting with regard to its drive scheme.
Aspect the service lift of the type that the present invention mentions in beginning, have first by suspension arrangementDrive chain and the mode preferably with the second drive chain realize its based on object, described drivingChain can be placed in the fixed point of building, and at drive unit described in described building for drivingEach of chain has one or more gears, the side that described gear and drive chain transmit with powerFormula engages, to the rotation of gear is converted into moving upward or moving downward of service lift.
The present invention is based on known arrangement complete of the cable capstan winch at least needing track cable and safety cableEntirely abandon, its mode is to replace in this using one or two drive chain. Based on the drive scheme of chainProvide equally multiple advantages: due to the make of the chain that is designed to engage by gear, outstandingThe rigid phase of hang device improves significantly for known solution. Along the vibration of vertical directionMore not obvious. In addition, drive chain tool has the following advantages: described drive chain is in operation and twists with cableCompared with dish engages with cable wire by means of its traction sheave, cause significantly less because gear engagement is to drivingIn chain and produce noise.
Also have another advantage be: not only drive chain and also join to for power transmit drive chainGear can be manufactured in the mode of accreditation by means of simple mechanism technically, and and standardThe traction sheave of member, for example cable capstan winch is compared with the cable wire of corresponding batch production, can obviously more holdThe use of changing places, the selection providing to manufacturer for described traction sheave and cable wire is obviously more subject toLimit.
In the time of the gear drive service lift by means of on drive chain, due to the driving of form fitScheme is also expected lower wearing and tearing. Be several times as much as according to the maintenance intervals of lifter apparatus of the present inventionThe maintenance intervals of known system.
There is the motor driver with the first CD-ROM drive motor and the second CD-ROM drive motor by drive unitMode advantageously improve the present invention, described CD-ROM drive motor respectively with these two drive chains in oneEngage. Especially preferred, motor driver is made up of the first CD-ROM drive motor and the second CD-ROM drive motor.
Improved the fail safe of service lift by maintaining concurrently two drive systems. LogicalCross and maintain lastingly by this way two drive systems with two drive chains, in the situation of needsUnder in the time of the first motor driver fault for example the second driver always can be switched on. Preferably this twoIndividual system is in operation and turns round simultaneously. If a system down, at least can pacify for second soEntirely maintain load. In a preferred improvement project, these two systems are to make itCan promote load.
In an especially preferred embodiment, CD-ROM drive motor be configured to respectively have motor andThe variable speed driver of electromagnetic brake. Electromagnetic brake for locking motor reliably for servingLift is locked on its position reliably. This for example anti-fall equipment, as in the prior artThe anti-fall equipment of applying in the cable capstan winch of knowing, dispensable. Even for unlikely feelingsCondition, these two CD-ROM drive motors can once all shut down, and are arranged in these two CD-ROM drive motorsElectromagnetic brake is for protecting reliably service lift.
Another preferred embodiment in, CD-ROM drive motor have respectively centrifugal brake and forThe manually mechanism of release electromagnetic brake. Under extreme situation, there will be in theory following situation:All faults and operate in service lift and can not proceed after stopping of two CD-ROM drive motors.Under these circumstances, in this embodiment likely, discharge described one or more drivingThe electromagnetic brake of motor, so service lift starts to move downward. But decrease speed byBe limited in centrifugal brake on the high threshold of permission, make it possible to get rid of safety and injuredRisk. Preferably, maximum decrease speed in the scope of 22m/min to 28m/min (especiallyPreferably 25m/min).
Even if no longer guarantee electric energy supply, centrifugal brake also can be worked, and this makes system beAbsolute failure safety.
In an especially preferred improvement project of the present invention, drive unit is configured to chain continuous drivingMoving device (Kettendurchlaufantrieb), wherein the length of drive chain is confirmed as, and makes instituteState drive chain and in installment state, from suspension arrangement, extend through drive unit and side direction along peopleMember's holding mechanism extends, and states drive chain hang down in this place. The advantage of drive chain is: it can be withLow manufacturing technology expends and maintains in principle arbitrarily in length. Therefore, make for diverseAlways can use the identical parts of service lift together with its drive unit with place, andAnd place to use only must be selected and mate to the length of the drive chain of corresponding use. Thus for completely notThe amount of same parts has been improved in same place to use, and because scale effect shows intoThe raising of this efficiency.
In addition, simplified the mechanical realization of drive unit, driven because needn't be provided for collecting/reelingThe mechanism of moving chain.
According in another preferred embodiment of service lift of the present invention, drive chain is parallelGround is directed, preferably in the same side of service lift from the other process of personnel's holding mechanism, and borrowHelp tension weight and keep tensioning along vertical direction. In the first preferred replacement scheme, tensioningCounterweight is configured to the common tension weight for two drive chains. According to the second alternative scheme,Close-fitting heavily comprises two single counterweights. By being set, tension weight prevents that drive chain is at drive unitThe gear that middle meeting with respect to gear, especially drives jumps, and wherein tension weight makes drive chainPosition and orientation stable. If for two drive chains use common, keep this two drivingsThe tension weight of chain, has also guaranteed the parallel fixed of these two drive chains so thus simultaneously enduringlyTo.
Drive chain driven device preferably repeatedly turns to. Turn on the one hand in particular for making drive chainSubstantially perpendicularly directed with the center of gravity of personnel's holding mechanism above personnel's holding mechanism, with person who happens to be on hand for an errandMember's holding mechanism can " straight line dangles " and guiding better in architectural shaft for example. In addition,By drive chain once, preferably repeatedly turn to guarantee chain around the power of transmission, connect with motor driverThe cornerite of the gear connecing is enough large, to there is all the time abundant tooth to keep engaging with chain. Fall thusThe low load of the point-like to each tooth, and generally by the minimise wear of drive system.

Additional gear that turn to, that do not drive also contributes to except tension weightChain is not jumped and remains with the power of the gear driving to coordinate.
Another preferred embodiment in, service lift according to the present invention has lift restrictionDevice, described lift restraint device is configured to, in the time exceeding predetermined chain load according to drive unitAnd relative motion between personnel's holding mechanism stops the motion up or down of service lift. ThoughSo service lift is along the danger of vertical direction vibration by using drive chain with respect to steelSuo Mingxian reduces, but in the situation that service lift speed changes, lucky at motion processThe power (chain load) that when starting or finishing, appearance is worked to drive chain along vertical direction at any timeBetween restricted raising. Turned out to be advantageously, whole drive assembly design is self rigidityStructure, and personnel's holding mechanism is also designed to the structure of self rigidity, but make on the contrary these twoUnit can relative to each other move. This obtains by means of the possibility that the number of the free degree is kept littlelyTo the system that mechanically can simply control.
Preferably, in this lift restraint device, CD-ROM drive motor is arranged on common Loading Plate, whereinDescribed Loading Plate be bearing in pivotly on personnel's holding mechanism and by spring element towards personnelThe direction pretension of holding mechanism. Preferably, pivoting action stops by means of damper element. PivotableAxis is preferably flatly offset about the point of force application in suspension arrangement side of suspension arrangement, described pivotShaft axis is interpreted as lower axis, Loading Plate around described axis with respect to personnel's holding mechanism pivotTurn. Because pivot axis is from the point of force application laterally offset of suspension arrangement side, obtain: from building sideSuspension arrangement set out, hold the normal force of drive chain and have around the thick stick of the pivot axis of Loading PlateBar effect (even little). Because producing Loading Plate, this leverage holds machine with respect to personnelThe pivoting action of structure, described personnel's holding mechanism is positioned at again the chain of suspension arrangement side with its mass cgIn the vertical line of line. As an alternative, preferably, pivot axis and power transmission shaft are coaxially directed. ByThis preferably only triggers the pivoting action of Loading Plate by the moment of torsion of driver.
By spring element, at the direction pretension towards personnel's holding mechanism, spring opposing is owing to hanging dressThe normal force of putting the chain line of side improves and the deflection that causes. Therefore, can set by the intensity of pretension,From improving, which kind of tractive force starts pivoting action actually.
Preferably, be arranged on personnel's holding mechanism or Loading Plate for the interrupt switch of drive unit,Make described interrupt switch occur the action direction of spring element against pretension of Loading PlateIn the situation of predetermined deflection, be triggered. In the situation that triggering interrupt switch, CD-ROM drive motor is preferably straightConnect and stop. The damper element being preferably arranged on service lift holds machine at Loading Plate and personnelBetween structure, work, to prevent that interrupt switch is just triggered in the time starting to travel suddenly.
Service lift another preferred embodiment in, this service lift has for drivingThe device of the tension force monitoring of moving chain. During the service life of each chain, this causes chain to elongate. In additionExtremely rare in the situation that, can cause each chain member lost efficacy and demonstrated cracking, ought split thusWhen line is not found in time, overall cochain can rupture.
Due to complicated technically to the vision monitoring of drive chain, so preferably, for tension forceThe device of monitoring has the gear of preferred non-driving for each drive unit, described gear can be relativeIn the non-parallel ground deflection of corresponding drive chain and by means of spring element towards corresponding drive chainDirection press to this drive chain. Preferably, be arranged on for the interrupt switch of drive unit in additionOn the gear holding device moving on gear, together with spring element or on Loading Plate, makeBe triggered in the case of occurring or exceeding interrupt switch the predetermined deflection of gear. By means of bulletSpring element works as follows at the gear that is pressed towards described drive chain towards the direction of drive chain: will driveChain is extruded from its orientation default due to chain tension force. Chain tension force is worked for this reason.
Be arranged on interrupt switch in lift restraint device and excellent for the interrupt switch of drive unitChoosing is according to identical operation logic work. Reaching or exceeding tooth gear or supporting gearIn the situation of the predetermined deflection of wheel holding device, the power supply of motor driver is interrupted. These are two years oldIndividual motor is turned off.
Especially preferred, in service lift according to the present invention, these two CD-ROM drive motors andThe gear same design for these two drive chains engaging with drive chain, and in addition these two driveAlso same design of moving chain. Provide thus a kind of drive system of fully redundance, described drive systemThe in the situation that of the first Transmission Trouble, ensure when another power train maintenance when malfunctioning of the first power trainLoad.
