Certainly, described dynamic assembly 65 can also adopt following scheme:
The form that adopts common motor, common coupler, drg and reductor to separate can be reached for equally to subtract and shake the purpose that reel provides power, and with low cost, easy for installation.
Further, described dynamic assembly 65 comprises torque motor, stall torque coupler and reductor, and the output shaft of described torque motor is connected with described reductor by described stall torque coupler.
Adopt torque motor to provide more stable power for sway stabilisation system, compact conformation, control conveniently simultaneously.
Within these schemes all should be included in protection domain of the present utility model.
Further, described dynamic assembly 65 also comprises drg.
Be convenient to like this dynamic assembly is controlled, improve stabilizing efficiency.
In the above-described embodiments, preferably, described lifting mechanism comprises lifting reel 40 and lifting wire rope 30, described lifting reel 40 is fixed on described dolly, one end of described lifting wire rope 30 is fixed on described dolly, and the other end is fixed on described lifting reel 40 after walking around pulley on described sling upper rack 20.
Preferably, described the first rope, the second rope, the 3rd rope, the 4th rope are steel rope.
The lifting of sling upper rack has independently lifting mechanism realize, lifting mechanism and sway stabilisation system are separate, and that the steel rope in sway stabilisation system can be done is thinner, reduces movement interference, reduces production costs simultaneously.
Lower mask body is introduced subtracting of elevator machinery described in the utility model and is shaken principle:
After the arranged in form quadruplet of Fig. 1 and Fig. 4 novel antirolling apparatus and leading sheave, first rope the 11, second rope the 21, the 3rd rope the 31, the 4th rope 41 has just formed rope system equal in length but mutually noninterfere in the space.
As extremely shown in Figure 10 in Fig. 8, upper dolly assembly 60 is arranged on the lower dolly circular orbit 71 of lower dolly assembly 70, and whole lower dolly assembly 70 is arranged on the trolley track of crane girder, can put into the level run that direction realizes lower dolly assembly 70 along trolley track, and upper dolly assembly 60 can turn round above lower dolly circular orbit, be convenient to suspender 10 and goods 100 to case; And whole hoisting crane can be realized the movement on the cart direction along the cart track travel that lays at harbour or harbour, is convenient to the carrying of goods on the cart service direction.
The process of inhibition that waves on the trolley travelling direction: as Fig. 4 and shown in Figure 10, when dolly assembly 70 travels along the trolley track on crane girder instantly, especially when lifting mechanism and trolley travelling interlock, suspender 10 and goods 100 will occur asynchronous with lower dolly assembly 70 operations, waving on the trolley travelling direction namely occur.When suspender 10 and goods 100 swing to left, subtracting in the first drive division 1 shakes subtracting in reel and the 4th drive division 4 and shakes reel and will pull sling upper rack 20 with constant pulling force, suppressing sling upper rack 20 swings to left, at this moment subtracting of the first drive division 1 and the 4th drive division 4 shakes reel and putting rope, simultaneously the second drive division 2 and the 3rd drive division 3 subtract shake reel will rope closing;
When suspender 10 and goods 100 when next oscillation period swings to the right, the subtracting of the second drive division 2 and the 3rd drive division 3 shakes reel will put rope, and constant pulling force pulls sling upper rack 20, suppress sling upper rack 20 to right-hand swing, at this moment the first drive division 1 and subtracting of the 4th drive division 4 shake reel in rope closing, several circulations and so forth just can consume the energy that suspender 10 and goods 100 swing.
The process of inhibition that waves on the cart service direction: when crane moves, the swing on suspender 10 and goods 100 fore-and-aft directions will occur, waving on the cart service direction namely occur.As Fig. 4 and shown in Figure 10, when suspender 10 and goods 100 swing backward, the subtracting of the 3rd drive division 3 and the 4th drive division 4 shakes reel will pull sling upper rack 20 with constant pulling force, suppressing sling upper rack 20 swings left, at this moment the first subtracting of drive division 1 second drive division 2 shakes reel in rope closing, and simultaneously subtracting of the 3rd drive division 3 and the 4th drive division 4 shakes reel and will put rope;
When suspender 10 and goods 100 when next oscillation period swings forward, the subtracting of the first drive division 1 and the second drive division 2 shakes reel will put rope, and constant pulling force pulls sling upper rack 20, suppress sling upper rack 20 swing forward, at this moment the 3rd drive division 3 and subtracting of the 4th drive division 4 shake reel in rope closing, several circulations and so forth just can consume the energy that suspender 10 and goods 100 swing.
During this period, how much all gathering by coder 61 of rope closing amount finally feeds back to PLC, and then controls the novel corresponding frequency converter of antirolling apparatus of quadruplet and control rotating speed and torque, reach speed and torque to three-in-one reductor assembly, and the control of direction.
The hoisting crane that the utility model provides, by arrange dexterously the antirolling apparatus that quadruplet is novel on hoisting crane, can realize inhibition and elimination that suspender and goods are waved at moving of car direction and cart service direction, and have lightweight, the characteristics such as cost is low, failure rate is low.
The above is only preferred embodiment of the present utility model, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
