Description
Technical field
The utility model relates to the hoisting crane field, particularly a kind of ultrahigh pump lift monkey.
Background technology
Along with metallurgical and other all kinds of heavy-duty machineries constantly to the improvement of large scale development and traditional handicraft, the requirement of ultrahigh pump lift hoisting crane is increasing.But the suspender of ultrahigh pump lift hoisting crane adopts lifting hook pulley group canoe usually at present, and the length of steel wire is longer, and the length of steel wire is at least the twice lift.Suspender only has an equalizing bar, the two ends of equalizing bar respectively are provided with a movable pulley, when ultrahigh pump lift hoisting crane during in the decline process, with respect to high-lift, distance between the steel rope of movable pulley both sides almost can be ignored, and two sections steel ropes can be similar to regard coincidence as point-blank, the knotting so the steel rope of movable pulley both sides is easy to twist, steel rope passes through to be ground pine easily behind the pulley, and then loose voluntarily.Therefore there is following shortcoming in existing ultrahigh pump lift hoisting crane: the reel dimensional structure is large, the rope drift angle is large under the steel rope, steel rope reverses knotting, loose voluntarily because sth. made by twisting steel rope occurs around power release in ultrahigh pump lift, four suspension centres asynchrony phenomenon occurs in the decline process.Therefore, existing ultrahigh pump lift hoisting crane affects the normal use of lifting mechanism to a certain extent, can't satisfy the requirement of ultrahigh pump lift (H=370m) weight-lifting equipment.
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, cause easily 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 causes easily 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 mechanism arrangement structures 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 arrangement structure is larger; Be arranged in parallel for two reels such as closed-type double action crank press winding drum lifting mechanism arrangement structure 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 arrangement structure is not compact, need two retarders to realize transmission, complex structure.
