Description
Technical field
The utility model relates to crane hoisting mechanism, particularly the ultrahigh pump lift crane hoisting mechanism.
Background technology
The conventional hoist lifting mechanism is arranged as reel-reductor (parallel shafts)-drg-electrical motor at present, and steel rope is realized different multiplying by running block, fixed pulley group.The wirerope-winding amount that large lifting altitude (lift) and a large liter weight have determined to be wound on the hoisting drum is very large, when adopting traditional screw type reel multilaminate coiled, above each layer steel rope of the second layer and the second layer can produce the disorder cable phenomenon in winding process, and serious wear between the rope, reduced the service life of steel rope, and need also to increase that there are complex structure in rope guide, rope guide, inflexible defective that leads, easily cause stuck phenomenon.The ultrahigh pump lift hoisting crane uses tradition to hoist and arranges that drawback is rope capacity long (lifting altitude is taken advantage of the multiplying power number), causes drum diameter super large and length overlength.Reductor causes the reductor cost to increase because the restriction of drum diameter has to strengthen width between centers.The excessive steel rope disorder cable that easily causes of the long then steel rope of reel length lifting process deflection angle.
Two winding drum lifting mechanisms are the problem methods commonly used that solve ultrahigh pump lift hoist roller wiring.At present, the method that adopts two reels to twine, be divided into two types of open type and encloseds, illustrated in figures 1 and 2 as in interim " the wiring problem of the ultrahigh pump lift hoisting crane " paper of Chinese periodical " hoisting crane machinery " 1988 07 respectively, it is that multiplying power does not add change that two reels are reeled to original total rope, just being shared the load of an original reel and restricted by two reels is that multiplying power reduces half, thereby lifting altitude can double.But, the open type pair winding drum lifting mechanisms shown in Figure 1 such as this paper are that the two reels that be arranged in parallel link to each other with same retarder by gear transmission, the pivot center of retarder is parallel with the pivot center of two reels, electrical motor links to each other with retarder by drg, motor reel and drum shaft are arranged in parallel, and the shared volume of this lifting mechanism is larger; Be arranged in parallel for two reels such as closed-type double action crank press winding drum lifting mechanism shown in Figure 2 in the paper, motor reel is set in parallel between the two winding drum, the two ends of electrical motor respectively are distributed with one and are used for the retarder parallel with the pivot center of reel with its pivot center of corresponding reel connection, this closed-type double action crank press winding drum lifting mechanism is not compact, need two retarders to realize transmission, complex structure.
Summary of the invention
The purpose of this utility model provides a kind of ultrahigh pump lift crane hoisting mechanism, to solve the not compact problem of ultrahigh pump lift crane hoisting mechanism structure in the prior art.
In order to address the above problem, the utility model adopts following technical scheme: the ultrahigh pump lift crane hoisting mechanism, comprise electrical motor, the drg that is in transmission connection with the mouth of electrical motor, the retarder that is in transmission connection with the mouth of drg, two reels that axis is parallel, described reel connects by gear transmission, the mouth of retarder is in transmission connection by gear and one of them reel, described retarder is the rectangular axis retarder, described motor axis and spool axis vertical distribution, the rectangular axis retarder comprises the output shaft that is parallel to spool axis and the input shaft that is parallel to motor axis, retarder, drg and electrical motor are distributed in axial the same side of two reels from front to back successively along motor axis.
End away from retarder of described reel is provided with height hoisting capacity integrated display.
End away from retarder of described each reel is provided with sure brake.
Described reel is the dual slope rope groove drum, and described dual slope rope groove drum comprises along the alternatively distributed dual slope grooving of axis and ladder baffle ring.
The ultrahigh pump lift crane hoisting mechanism that the utility model provides, retarder is the rectangular axis retarder, the rectangular axis retarder comprises be used to the transverse axis that is parallel to spool axis and the longitudinal axis that is parallel to motor axis, motor axis and spool axis vertical distribution, retarder, drg and electrical motor are distributed on the same straight line of positive side of the same side of two reels from front to back successively, whole distributed architecture of the present utility model is compact, make suspender less apart from large Car Track Derivative limit on the left or on the right, increased the running space of dolly and the stability of operation.
Further; end away from retarder of reel of the present utility model is provided with height hoisting capacity integrated display; height hoisting capacity integrated display makes that Real Time Monitoring shows the height that hangs thing in the process of hanging, and the weight of suspension centre load, according to different control Node Protection hoist mechanisms.
Further, the end away from retarder of each reel of the present utility model is provided with sure brake, and the drg of this sure brake and electrical motor, deceleration pusher side forms double insurance, prevents that contingency from occuring.
Further, reel is the dual slope rope groove drum, described dual slope rope groove drum comprises dual slope grooving and ladder baffle ring, fold line grooves is comprised of two sections straight line groovings and two sections oblique line groovings, every section oblique line grooving moves into half pitch vertically, and each all grooving moves into a pitch vertically by two sections oblique line groovings.The ladder baffle ring has the effect of lifting and guiding steel wire rope, can make steel rope smoothly successfully be transitioned into the upper strata by lower one deck, and levels steel rope cross transition is fixed on grooving oblique line section, ensuing steel rope will by the sequential volume of straight line-intersection-straight line-intersection around.Therefore, adopt fold line grooves and ladder baffle ring to replace traditional rope-arranging mechanism to realize the multilaminate coiled and proper alignment of steel rope.
