Abstract
The utility model discloses a kind of monkey lifting mechanism, comprise electrical motor, retarder, lifting reel and cable drum, the output shaft of electrical motor is connected with the input shaft of retarder by coupler, the output shaft of retarder is connected with the imput shaft of lifting reel, described lifting reel is connected by gear drive with between cable drum, and described gear drive has the transmitting ratio that the speed of the speed of cable drum retractable cable and lifting reel ascending, descending suspender is consistent.Owing to there is the transmitting ratio making the speed of the speed of cable drum retractable cable and lifting reel ascending, descending suspender be consistent with gear drive, and gear drive has the fixing advantage of transmitting ratio, therefore between lifting reel and cable drum, utilize gear drive can make to have good synchronism between lifting reel and cable drum, ensure the normal operation of hoisting mechanism for trolley.
Description
Technical field
The utility model relates to crane facility field, is specifically related to a kind of monkey lifting mechanism.
Background technology
In the hoisting crane being equipped with electric lifting tool, be provided with cable drum, cable drum is for Large-scale Mobile equipment provides propulsion source, controls the cable winder of power supply or control signal.Cable drum mainly adopts spring-driven cable drum and motor-driven cable drum, wherein the principle of work of spring-driven cable drum is similar to metallic tape, volute spring is utilized to carry out rolling cable for power, when cable is drawn out, collect volute spring and energy storage, when external force is eliminated, energy released by spring, reel automatic winding cable.Spring fatiguability, service life is short, for all certain limitation of the extra high workshop of lifting altitude.Cable drum often adopts the direct motor drive coaxial with the reel being wound with cable, after receiving signal, reel main story or reversion, receive, roll up cable to make cable up-and-down movement together with the lift system of hoisting crane, and provide control signal to suspender, make suspender make the action of setting.But the cable drum of this kind of structure drives owing to there being independent motor, the lifting reel controlling sling lifting drives lifting reel to rotate by electrical motor after retarder slows down, cable drum can not hoist with control suspender well, the lifting reel of landing keeps synchronism, particularly when suspender declines, if suspender is under the driving of lifting reel, descending speed is too fast, and the cable drum that now control cables declines makes the descending speed of cable be less than the descending speed of suspender, so now cable can bear larger pulling force, easy damage cable, even cause the accident.
Summary of the invention
The purpose of this utility model is to provide a kind of monkey lifting mechanism, has solved the technical matters of poor synchronization between existing cable drum and lifting reel.
To achieve these goals, the utility model adopts following technical scheme: a kind of monkey lifting mechanism, comprise electrical motor, retarder, lifting reel and cable drum, the output shaft of electrical motor is connected with the input shaft of retarder by coupler, the output shaft of retarder is connected with the imput shaft of lifting reel, described lifting reel is connected by gear drive with between cable drum, and described gear drive has the transmitting ratio that the speed of the speed of cable drum retractable cable and lifting reel ascending, descending suspender is consistent.
Described gear drive comprises driving gear and driven gear, and described driving gear is fixedly connected with the driven shaft of lifting reel, and described driven gear is fixedly connected on the turning cylinder on cable drum.
The pivot center of described lifting reel and the pivot center of cable drum are parallel to each other, and described lifting reel and cable drum are positioned at the same side of retarder.
The outside of described coupler is arranged with drg.
Described coupler is plum coupling.
The beneficial effects of the utility model are: lifting reel of the present utility model is connected by gear drive with between cable drum, gear drive has the transmitting ratio that the speed of the speed of cable drum retractable cable and lifting reel ascending, descending suspender is consistent, and gear drive has the fixing advantage of transmitting ratio, therefore between lifting reel and cable drum, utilize gear drive can make to have good synchronism between lifting reel and cable drum, ensure the normal operation of hoisting mechanism for trolley.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment of the present utility model.
Detailed description of the invention
The embodiment of a kind of monkey lifting mechanism of the utility model, as shown in Figure 1: comprise electrical motor 1, drg 4, retarder 5, cable drum 10 for the lifting reel 7 and folding and unfolding cable that control sling lifting, the output shaft of electrical motor 1 is connected with one end of transmission shaft 2, the other end of transmission shaft 2 is connected with the input shaft of retarder 5 by coupler 3, the outside of coupler 3 is arranged with drg 4, when braking, two watts of shape slipper of drg 4 are stuck on the shell of coupler 3.The output shaft of retarder 5 is connected with the imput shaft 71 of lifting reel 7, and the driven shaft 72 of lifting reel 7 is connected with the turning cylinder 9 of cable drum 10 by gear drive, and imput shaft 71, the driven shaft 72 of lifting reel 7 assemble with lifting reel 7 coaxial line.Lifting reel 7 is parallel to each other with the pivot center of cable drum 10, and lifting reel 7 and cable drum 10 are positioned at the same side of retarder 5, and this arrangement, compact conformation, takes up room little.Gear drive comprises driving gear 11 and driven gear 8, driving gear 11 is fixedly connected with the driven shaft 72 of lifting reel 7, driven gear 8 is fixedly connected with the turning cylinder 9 of cable drum 10, the transmitting ratio between driving gear 11 and driven gear 8 can ensure the ascending, descending suspender of lifting reel 7 hasten be consistent with the speed of cable drum 10 retractable cable.Lifting reel 7 is provided with the grooving for wirerope-winding, and cable drum 10 is provided with the grooving that current supply cable is wound around.
In the present embodiment, the pivot center of lifting reel and cable drum is parallel to each other, and is convenient to lifting reel and cable drum is arranged on monkey, and spur gear wheel can be adopted between lifting reel and cable drum to be in transmission connection; In other embodiments, the pivot center of cable drum and lifting reel also can be arranged vertically mutually, utilizes bevel drive.
In other embodiments, gear drive also can be set to two groups, as long as total gear drive transmitting ratio meet the requirement hastening to be consistent with the speed of cable drum retractable cable of the ascending, descending suspender of lifting reel.
In the present embodiment, the output shaft of electrical motor is connected with transmission shaft, transmission shaft is connected with the input shaft of retarder by coupler again, coupler is gear coupling, transmission shaft can coaxiality error between compensated motor and retarder, in other embodiments, if coupler adopts plum coupling, also can play the effect of compensating axial, radial error, now can save transmission shaft.
