Abstract
The utility model discloses a single-drum electric block and a crane adopting the same. The crane adopting the single-drum electric block comprises the single-drum electric block suspended under a main beam, wherein the single-drum electric block comprises a single drum, hoisting mechanisms are arranged on the drum, each hoisting mechanism comprises a steel wire rope and a hanging tool, the steel wire rope is wound on the drum, the hanging tool is arranged on the steel wire rope, the number of the hoisting mechanisms arranged on the drum is at least two sets, the hoisting mechanisms are parallelly arranged in the axial extending direction of the drum, the steel wire ropes arranged on the hoisting mechanisms are all wound on the drum in the axial extending direction of the drum, and the steel wire ropes of different hoisting mechanisms are wound in different regions of the drum. The utility model has the advantages that at least two sets of hoisting mechanisms are assembled on the single drum, when the crane is used for hoisting and conveying longer articles, the hanging tools of different hoisting mechanisms can be used for simultaneously hanging different hanging points of the same heavy objects, and the objects are not easy to deflect when the crane is used for hoisting and conveying longer objects or objects with undefined gravity center.
Description
Technical field
The utility model belongs to the crane facility technical field, and particularly a kind of single drum electric block also relates to a kind of hoisting crane that uses above-mentioned electric block simultaneously.
Background technology
Be illustrated in figure 1 as on the present hoisting crane employed electric block and comprise reel assembling 21, in reel assembling 21, be provided with single reel, one cover lifting mechanism is set on single drum, and this lifting mechanism comprises steel rope 22 that is wrapped on the single drum and the suspension hook 23 that is suspended on the steel rope.Because it is single cover lifting mechanism, when long article of crane for hoisting or the indefinite article of center of gravity, article are rising or can not the held stationary state when mobile, occur easily tilting to wave, to operator, peripheral equipment and all there is bigger security threat in hoisting crane itself, safety misadventure takes place easily like this.
The use producer that has handling for convenience often increases special-purpose auxiliary suspender than long article under suspension hook, just need like this to consider auxiliary suspender deadweight when former electric block is selected in design for use, can finish the lifting task safely, efficiently to guarantee it.But be to use special-purpose auxiliary suspender to increase the design use cost of hoisting crane complete machine on the one hand, also have the problem of long-term highly energy-consuming simultaneously.
The utility model content
The purpose of this utility model provides a kind of single drum electric block, the more technical matters of potential safety hazard when solving that handling is than long article or the indeterminate article of center of gravity in the prior art, the utility model also provides a kind of hoisting crane that uses above-mentioned single drum electric block simultaneously.
The single drum electric block that is provided in the utility model adopts following technical scheme: the single drum electric block, comprise single reel, on reel, be equipped with lifting mechanism, lifting mechanism comprises steel rope that is wrapped on the reel and the suspender that is arranged on the steel rope, lifting mechanism on the described reel along drum shaft to parallel at least two covers that are furnished with of bearing of trend, steel rope on the lifting mechanism all is wrapped on the reel along the direction that extends axially of reel, and the steel rope of different lifting mechanisms is wrapped in the zones of different of reel.
The suspender of described different lifting mechanisms is highly equal when the lifting article.
The hoisting crane of the use single drum electric block that is provided in the utility model adopts following technical scheme: the hoisting crane that uses the single drum electric block, comprise the single drum electric block that is suspended on the girder below, this single drum electric block comprises single reel, on reel, be equipped with lifting mechanism, lifting mechanism comprises steel rope that is wrapped on the reel and the suspender that is arranged on the steel rope, lifting mechanism on the described reel along drum shaft to parallel at least two covers that are furnished with of bearing of trend, steel rope on the lifting mechanism all is wrapped on the reel along the direction that extends axially of reel, and the steel rope of different lifting mechanisms is wrapped in the zones of different of reel.
The suspender of described different lifting mechanisms is highly equal when the lifting article.
Single drum electric block provided by the utility model, because assembling at least two cover lifting mechanisms on the single reel, like this when handling during than long article, the suspender of different lifting mechanisms is the different suspension centres of the same weight of suspender simultaneously, like this when long article of handling length or the indefinite article of center of gravity, article just are not easy to deflect, and have so just improved the safety of handling process.Because adopt many cover lifting mechanisms to lift by crane simultaneously, when the lifting long article, just saved the auxiliary suspender of additive incrementation like this, reduced production and use cost.And owing to adopt many cover lifting mechanisms, it possesses a plurality of suspension centres, so just can a plurality of article of while handling when the small-sized workpiece of lifting, thus improved work efficiency greatly.

Fig. 1 is the structural representation of electric block in the prior art;
Fig. 2 is the structural representation of a kind of embodiment of single drum electric block in the utility model;
Fig. 3 is the left view of Fig. 2;
Fig. 4 is the structural representation of the hoisting crane of the single drum electric block shown in use Fig. 2.
The specific embodiment
As Fig. 2, shown in Figure 3, a kind of single drum electric block, comprise the reel assembling 2 that is lifted on traveling gear 4 belows by link span device 6, reel assembling 2 comprises single reel 3 and is installed in the retarder 1 and the drive motor 7 at the two ends of reel 3, be equipped with on reel 3 along three cover lifting mechanisms of the parallel setting of reel axial direction extension, every cover lifting mechanism includes steel rope 5 that is wrapped on the reel and the suspender 8 that is lifted on the steel rope 5.
The steel rope 5 of lifting mechanism all is wrapped on the reel 3 along the direction that extends axially of reel, and the steel rope of different lifting mechanisms is wrapped in the zones of different of reel, and the suspender 8 of different lifting mechanisms is highly equal when the same article of lifting.
As shown in Figure 4, a kind of hoisting crane that uses the single drum electric block, comprise the single drum electric block 30 that is suspended on I-beam section girder 20 belows, single drum electric block 30 structures such as Fig. 2 in the present embodiment, shown in Figure 3, the single drum electric block, comprise the reel assembling 2 that is lifted on traveling gear 4 belows by link span device 6, reel assembling 2 comprises single reel 3 and is installed in the retarder 1 and the drive motor 7 at the two ends of reel 3, be equipped with on reel 3 along three cover lifting mechanisms of the parallel setting of reel axial direction extension, every cover lifting mechanism includes steel rope 5 that is wrapped on the reel and the suspender 8 that is lifted on the steel rope 5.
Three cover lifting mechanisms are set on single reel in the utility model, when specifically implementing, can be according to the many covers of the design size design lifting mechanism of concrete operating needs and reel, to satisfy operating needs.
