Preferably, driver element is common motor, further reduces equipment cost.
The tower machine that this preferred embodiment provides, its specific implementation process is as follows:
The output speed n of motor0Through stepless speed-regulating device (gear ratio ic) after speed change, the rotating speed that arrives sun gear 151 isns＝n0/ic. Because the driving gear of the first gear pair 131 is fixed on driving belt pulley shaft 111, its rotating speed and motor turn simultaneouslySpeed is identical, i.e. n0, through the preposition fixed shaft gear train deceleration device 13 (total reduction ratio-i that slows downa, "-" represents contrary with motor speed)After, the rotating speed that arrives gear ring 157 is nr＝-n0/ia, according to the characteristic of planetary mechanism, have
ns+anr-(1+a)nc, the characterisitic parameter that wherein α is planetary mechanism, the gear ratio that its value is gear ring and sun gear.
So
From the speed ratio that planet carrier 155 is exported that is input to of motor
Due to icCan be at icmin～icmaxInterior variation continuously, ratio coverageioAlso can change continuously within the specific limits,Its excursion is
Be that ratio coverage is
For a certain specific stepless speed change device, dcAnd icminFor definite value, by conversionValue, can obtain need doValue, for example, dc＝5.5，icmin=0.4, need do=20,Value 2.883.
Visible, the present invention can obtain very large ratio coverage, meets tower machine heavy-duty low-speed, underloading requirement at a high speed.
Weak link of the present invention is at metal tape 115, and its failure mode is fracture. If metal tape 115 ruptures, sun gear 151There is no the power from motor, its rotating speed declines gradually, and the rotating speed of exporting from planet carrier 155 is corresponding decline also, therefore metalWhile being with 115 just fracture, whole system is safe. But while dropping to a certain value along with sun gear 151 rotating speeds, planet carrier 155The rotating speed of output reduces to 0, then oppositely accelerates to rotate, and produces dangerous. Safeties 17 can play a protective role, and prevent above-mentionedDangerous generation. Its protection main process is as follows:
The driving gear 171 of safeties 17 and the speed reducing ratio i of driven gear 175bBe slightly larger than icmax, due to driving gear 171Consistent (the n of rotating speed of rotating speed and driving belt pulley shaft 1110), so while normally work, the rotating speed (n of driven gear 1750/ib)All the time be less than the rotating speed (n of passive belt wheel shaft 1190/ic), one-way clutch 177 is not worked. In the time that metal tape 115 lost efficacy,Sun gear 151 and passive belt wheel shaft 119 rotating speeds decline, when dropping to n0/ibTime, one-way clutch 177 is worked, and makes passive beltThe rotating speed of wheel shaft 119 is consistent with the rotating speed of driven gear 175, no longer decline, the rotating speed of exporting from planet carrier 155 also no longerFall, the movement velocity of workpiece also no longer changes, and runs to terminal with this speed.
Clutch 179 plays dual fail-safe effect together with one-way clutch 177. Clutch 179, in normally open, is worked as metalWhile being with 115 inefficacy, obtaining instruction and engage, making the rotating speed of passive belt wheel shaft 119 consistent with the rotating speed of driven gear 175. ByBy hydraulic control, and be according to the passive work of instruction in clutch 179, action is understood some and is lagged behind, therefore one-way clutch 177Can make up the defect of clutch 179.
The effect of idle pulley 173 is the rotation directions that change driven gear 175, makes it consistent with passive belt wheel shaft 119 rotation directions.
As can be seen from the above description, the above embodiments of the present invention have realized following technique effect:
1, stepless speed-regulating device utilizes metal belt type stepless variable device as arrangements for speed regulation, replaces the speed-regulating function of original motor,Motor only plays the effect that power is provided, and therefore the requirement of motor and controller reduces, and designs simplification only need to use commonMotor, reduced cost; And stepless speed change device speed governing is steady, nothing is impacted.
2, use planetary mechanism to be combined with metal belt type stepless variable device, the speed reducing ratio of system is increased, ratio coverage increases,Can meet tower machine heavy-duty low-speed, underloading requirement at a high speed.
3, system works is safe and reliable, even if safeties have ensured that, in the time that metal tape lost efficacy, whole system also can complete safelyHoist or decline work.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for those skilled in the art, the present invention can have various modifications and variations. Within the spirit and principles in the present invention all, any amendment of doing, etc.With replacement, improvement etc., within all should being included in protection scope of the present invention.
