Abstract
The utility model relates to a box-shaped main beam web plate structure of a bridge type crane, which is composed of a waveform main web plate 1, a flat auxiliary web plate 2, a lower cover plate 3 and an upper cover plate 4, wherein the waveform main web plate is in a waveform which is modified by the flat web plate arranged in the box-shaped main beam along a longitudinal direction according to the change of a sinusoid function; the number of the waveforms is counted according to different main beam spans. The utility model adopts the arrangement proposal of a flat web plate and a waveform web plate to evidently increase the stability of the web plate in a vertical direction. Because the vertical stiffness of the waveform web plate is greater, the waveform web plate is used as a main web plate, and the other flat web plate is used as an auxiliary web plate; namely, the utility model can adopt a deflective track box type main beam structure with a deflective track, thus the waveform web plate can fully exert the characteristic of greater vertical stiffness and the greater horizontal stiffness can also be ensured.
Description
One, technical field: belong to the handling machinery field.
Two, background technology: " logistics " occupies critical role as important " first-class " in the modern manufacturing industry in modern industry, and the efficient that improves material handling has crucial effects to the efficient that improves modern industry.Hoisting crane has irreplaceable effect as the major equipment of material handling in the big production of modernization, strengthen the research of hoisting crane and the material handling level of improving improving China are had great importance.The crane in bridge type that China is widely used in industries such as machinery, metallurgy, transportation has at present accounted for about 40% of China's hoisting crane.The crane span structure of crane in bridge type is a kind of mobile metal construction, is main load-carrying element.It is bearing the wheel load effect of fully loaded crane carriage on the one hand, it is again by supporting the cart operation wheel of crane span structure on the other hand, the total weight of fully loaded hoisting crane has been passed to factory building track and building structure, and the weight of crane span structure generally accounts for more than 60% of hoisting crane deadweight.Box girder is one of base model of crane in bridge type metal crane span structure, and common box girder structure mainly has the following disadvantages:
First, adopt the hoisting crane of common box girder structure design, many actual conditions are simplified and idealized, safety when adopting very big safety factor to guarantee the emergency case that runs in service, and elevator machinery is the equipment that maximizes very much, can not make model machine and test, and model test is same time-consuming expensive.
The second, traditional design method design-calculated crane safety coefficient is big, and consumption of raw material is many, and structure is reasonable inadequately, and efficient is low, can not well adapt to the big needs of producing of modernization.
Three, summary of the invention:
1, the purpose of this utility model is the box girder web is transformed, and develops a kind of later-model web structure-corrugated web, adopts the box girder of this structure littler than stress, the weight of original common box girder, and can reduce the quantity of strengthening rib.
2, the present invention realizes by following technical scheme:
Fig. 2 is the structural representation of box-shaped crane in bridge type, 5 is two box girders of box-shaped crane in bridge type among the figure, Fig. 3 is the A-A cutaway view Amplified image of Fig. 2, it is the constructional drawing of known slabbing web box girder, Fig. 1 is the design's box girder A-A cutaway view Amplified image, it is corrugated web box girder constructional drawing, a slabbing web in the box girder is longitudinally carried out shape be transformed into waveform by the sine curve function, formation is by waveform master web (1), straight secondary web (2), lower cover (3), the box girder that upper cover plate (4) is formed, waveform master web 1, straight secondary web (2) and lower cover (3), upper cover plate (4) welding, box girder is fixed on two end carriages (6).
Web arrangement of the present utility model adopt a web be corrugated web another still be slabbing web.The corrugated web waveform adopts sinusoidal waveforms, because sine curve has unified function expression: suppose that girder length is L rice, and then:
A-amplitude in y=Asin (the ω x+ ) formula, ω-cireular frequency, -initial phase.Waveform number N chooses according to different girder spans,
A=0.05～0.15 meter,
N is a girder length waveform number,
Slabbing web improves to corrugated web, is for a kind of purpose: make main beam structure more reasonable, to reduce reinforced rib, alleviate the girder deadweight.The utility model adopts the arrangement of a slabbing web and a corrugated web, can increase the stability of web significantly in vertical direction, because the vertical stiffness of corrugated web is bigger, with its web of deciding, another slabbing web is made secondary web, promptly adopt the inclined to one side rail box girder form of track offset, can give full play to the bigger characteristic of vertical stiffness of corrugated web like this, and can guarantee bigger horizontal rigidity.Major and minor web thickness of the present utility model is different with the major and minor web thickness of common box girder, major and minor web thickness is than the little 0.001-0.003 rice of common box girder web thickness, all the other girder sizes are consistent with common box girder, according to the hoisting capacity and the span of designed hoisting crane, can look into the rubber tyre gantry crane design handbook and draw.
3, the design's advantage is: the advantage that combines common girder, inclined to one side rail girder, and given full play to the effect of corrugated web, the common box girder of the stress amplitude ratio of this new structure reduces more than 16%, the girder weight ratio alleviated 30% originally, and can reduce the quantity of reinforced rib, girder processing is become easily, not only can save steel and the cost-cutting that crane span structure itself is consumed, can also save capex because of the stand under load that has alleviated the factory building structure simultaneously.
Four, description of drawings:
Fig. 1 is the design's box girder A-A cutaway view Amplified image, i.e. corrugated web box girder A-A cutaway view Amplified image, the 1st, waveform master web, the 2nd, straight secondary web, the 3rd, lower cover, the 4th, upper cover plate; Fig. 2 is the structural representation of box-shaped crane in bridge type, the 5th, and box girder, the 6th, end carriage; Fig. 3 is the A-A cutaway view Amplified image of Fig. 2, the constructional drawing of promptly known slabbing web box girder.
