Abstract
The utility model relates to a hoisting drum device of a crane, which comprises an upper pulley block and a sling pulley block. The hoisting drum device is characterized by further comprising a four-lap double-spiral-groove drum which is connected with the sling pulley block through a first steel wire rope and a second steel wire rope, the first steel wire rope and the second steel wire rope are sequentially wound through the four-lap double-spiral-groove drum, the sling pulley block, the upper pulley block, the sling pulley block and the four-lap double-spiral-groove drum. The hoisting drum device has the advantages of ensuring that one steel wire rope can still be used for hoisting heavy objects when the other wire rope is fractured since the four-lap double-spiral-groove drum is used for releasing or winding two wire steel ropes, thereby avoiding safety production accidents caused by dropping off the heavy objects due to the fracture of the steel wire ropes. Besides, compared with traditional hosting drum devices of cranes, the hoisting drum device is capable of greatly improving safety and security coefficient, and further is simple in structure and capable of being used on a general crane after a trolley of the crane is modified.
Description
Technical field
The utility model belongs to the elevator machinery field, particularly relates to a kind of crane hoisting drum device.
Background technology
Hoisting crane is widely used in fields such as nuclear power, military project, metallurgy, machinery, chemical industry, petroleum-based energy.During the crane for hoisting visual plant definitely the weight obscission can not take place.As taking place, may produce blast, leak, cause environmental pollution, even cause casualties.
At present, the winding drum device of hoisting crane is the double-rope reel or singly goes out rope reel, wherein the double-rope roll device is the lifting that realizes weight by the reel two ends opposite lay winding wire ropes of rotation direction, only be installed with steel cable, singly go out rope reel is then just realized weight by lay winding wire ropes spiral on single helical groove reel 6 or the multi-layer helical formula lifting (as shown in Figure 1).Above-mentioned two kinds of reels are all by the steel cable weight of slinging, in case above-mentioned serious consequence will appear in steel rope fracture suddenly in the lifting process.
Summary of the invention
A kind of safety is good, the crane hoisting drum device of vi have high safety for the technical matters that exists in the solution known technology provides for the utility model.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
A kind of crane hoisting drum device, comprise top sheave group and suspender assembly pulley, it is characterized in that: also include four rope stretching double spiral groove reels, four rope stretching double spiral groove reels link to each other with the suspender assembly pulley with second steel rope by first steel rope, and described first steel rope and second steel rope pass four rope stretching double spiral groove reels, suspender assembly pulley, top sheave group, suspender assembly pulley and four rope stretching double spiral groove reels successively.
The spiral fluted rotation direction from the reel two ends of described four rope stretching double spiral groove reels is opposite, and two spiral fluted rotation directions of every end are identical.
Advantage and the good effect that the utlity model has are:
After the utility model has adopted above technical scheme, use the release of four rope stretching double spiral groove reels or twine two steel ropes, can guarantee when fracture appears in steel cable, still there is steel cable can lift weight, the weight of having avoided invar silk fracture of rope and having caused drops and the industrial accident that causes, and crane hoisting drum device has more in the past increased substantially safety and conservative factor.And the utility model is simple in structure, only need improve dolly on common hoisting crane and partly can use.
Description of drawings
Fig. 1 is a crane hoisting drum device of the prior art;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the view in steel cable when fracture in the utility model;
The view of Fig. 4 when to be the utility model utilize another root steel rope lifting weight after the steel cable fracture.
Among the figure: 1, four rope stretching double spiral groove reels; 2, first steel rope; 3, second steel rope; 4, top sheave group; 5, suspender assembly pulley; 6, single helical groove reel.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 2 to Fig. 4, a kind of crane hoisting drum device, comprise top sheave group 4, suspender assembly pulley 5, four rope stretching double spiral groove reels 7, four rope stretching double spiral groove reels link to each other with suspender assembly pulley 5 with second steel rope 3 by first steel rope 2, and first steel rope and second steel rope pass four rope stretching double spiral groove reels 1, suspender assembly pulley 5, top sheave group 4, suspender assembly pulley 5 and four rope stretching double spiral groove reels 1 successively.
The spiral fluted rotation direction from the reel two ends on the four rope stretching double spiral groove reels 1 is opposite, and two spiral fluted rotation directions of every end are identical.
Operating principle of the present utility model is:
During normal condition, the rotation of four rope stretching double spiral groove reels, the steel rope on winding or the release reel.Through the top sheave device, suspender pulley gear hoisting heavy hoists or descend, pile up workpiece.As shown in Figure 3, Figure 4, when one in two steel ropes fracture suddenly, second wire cable rupture for example, second steel rope pitches, and bear the needs of weight weight because the design load of first steel rope can satisfy a rope short time, and the lifting center is constant, still can keep lifting state to weight, the operator can placement on the ground with weight safety after, row maintenance hoist roller has increased substantially safety again.
