Description
Technical field
The present invention relates to single-beam crane, more particularly to a kind of integrated main girder construction for single girder crane gear,
It is suitable for the crane girders such as bridge-type, gate-type.
Background technology
At present, as the industry-by-industry such as the rapid development of domestic economy, steel, thermoelectricity, petrochemical industry, mine, harbour is also fast
Speed forms the scale of oneself, and higher and higher requirement is it is also proposed to safe efficient, the energy-conservation of engineer equipment.Crane has
Simple in construction, the advantages that loading capacity is big, and floor space is small, be that mechanization is realized in workshop, stock ground, warehouse, mitigates muscle power
The important haulage equipment work, raised labour productivity, thus have a wide range of applications in the industry.In electrical equipment assembly line, smelting
The places such as golden industry, railway transportation, container terminal, warehouse dispatching, everywhere it can be seen that various cranes.Crane
Welcome new market on the export trade, but the influence of crane acceptor's beam length of domestic traditional type, it can not carry out
Container is delivered, and is mainly delivered with loose unpacked material, so not only need the freight charges of costliness can also because marine various adverse circumstances because
Element influence and influence the product quality of crane.
Today in constantly improve and progressively ripe for market economic system, for Novel crane research and development work
Propose higher requirement, traditional design concept, it is difficult to adapt to Socialist Market Economy Development and faced new
The needs of situation, it is more difficult to solve the new problem, the new situation that occur in development, it is therefore desirable to perfect grind is carried out to existing product
Study carefully and development.On the one hand, by the optimization of system, arrangement, so as to simplify production procedure, efficiency is improved, and then improve and produce
Quality；On the one hand, summary, mass, standardization are manufactured by improve crane products, improve operating efficiency,
On the other hand, by optimizing structure design, change traditional integrated main girder construction, design novel integral main beam structure pattern and
Mount scheme, cost of transportation is reduced, shortening is manufactured, the in-site installation cycle.
Because girder of the prior art is using steel plate indent or by steel plate assembly welding shaping, larger, the single lifting of girder deadweight
When machine is used for outdoor, the influence of wind load is considered when calculating cart operation power of motor.When the span of crane is larger,
Because being limited by transport, it is necessary to disintegrate to girder, complexity is not only made at disintegration, it is also relatively time-consuming during installation.When single-beam rises
When heavy-duty machine exports, because the size of subject container limits, very big difficulty is brought for old-fashioned structure.Need to carry out hair in bulk
Goods, sea-freight can corrode to lacquer painting, influence crane gear quality, while ocean freight in bulk is very high.Girder by tonnage and across
Degree influences, and the section of girder and structure type are more, makes cumbersome.Factory needs the library storage for carrying out sheet material standby, the profit of sheet material
It is not high with rate, waste is produced, it is standby to carry out library storage, equipment delivery cycle length.Acceptor's beam length limits, separate unit haulage vehicle
Can not more crane gears transport simultaneously, cost of transportation height.Box girder heavier-weight, it is right when tonnage, span are larger
The lifting capacity of crane in factory building requires, and tonnage is too small to be manufactured.Former girder disintegration joint is to disintegrate
Place welding two pieces of flanges, ring flange surrounding carry out with bore, scene be attached by bolt, be in the inside and outside lining plate of girder,
Inside and outside liner plate and girder web plate, upper and lower cover plate with boring, hand hole is opened on girder web plate, is attached by bolt,
Bolt is main stressed member, and its girder firmness and stability are poor.Multi-sheets are needed to carry out, with boring, making cumbersome, system
Make cycle length.Flange weight is larger, waste of material, multiple bolt connections, and in-site installation is inconvenient, and only bolt connection, existing
Assembly precision is low during the installation of field, influences product quality.Because the liner plate of girder joint is more, it may appear that leakage is sent out or showed during delivery
Group to position not to the problems such as, the problems such as having a generation group is to installation after sale and repeatedly, postpone installation progress.
Therefore, prior art needs further improvement and developed.
The content of the invention
In view of above-mentioned the deficiencies in the prior art, it is an object of the invention to provide a kind of for the whole of single girder crane gear
Body formula main beam structure, existing integrated main girder construction is split as several modular units, ensures integrated main girder construction
On the premise of intensity, reduce stock's specification of sheet material and section bar.
In order to solve the above technical problems, the present invention program includes：
A kind of integrated main girder construction for single girder crane gear, wherein, the integrated main girder construction is by upper cover plate, lower cover
Plate is formed with truss, and upper cover plate is arranged on truss upper surface, and lower cover is arranged on truss lower surface, and lower cover doubles as electric block
Track, electric block are arranged on lower cover, and cucurbit electric power system, cucurbit electric power system and electric block are provided with upper cover plate
Circuit connects.
Described integrated main girder construction, wherein, above-mentioned truss is by rectangular tube, square tube, channel-section steel, angle steel, H profile steel, welding
The shaped steel splicing group weldering such as steel pipe, I-steel or round steel forms.
A kind of integrated main girder construction for single girder crane gear provided by the invention, reduce sheet material and section bar
Stock's specification, integrated main girder construction fast transportation and quick assembling can be made, and use alignment pin and positioning shaft sleeve
Frame mode, after integrated main girder construction is assembled be alignment pin and positioning shaft sleeve is main stressed member, be ensure that whole
Intensity after the assembling of body formula main beam structure.Due to being spliced using section bar, older box-type structure fabrication is simple, fast；
Welding supply and demand is reduced, reduces wlding usage amount；Do not limited by order, girder " modular unit " can be subjected to running stock；
Because truss girder is spliced using shaped steel, steel utilization ratio is high, improves corporate profit, and in outdoor application, can be with
Ignore the influence of wind load.Designed using " modular unit ", girder only selects several specifications " modular unit " can
With tonnage and span all standing, stock's specification of reduction sheet material and section bar；Because the crane main screw lift of truss reduces, then add
Upper girder is designed using " modular unit ", and acceptor's beam length does not limit land transport vehicle, can the more same cars of crane gear
Transport, reduce cost of transportation；Using fabricated structure, girder point " modular unit " makes, and can improve factory building utilization rate.It is main
Beam is not limited when making by the crane load in factory building, and large-tonnage crane gear need not be installed in factory building and coordinates production system
Make, reduce energy consumption, connection between " modular unit " is attached using bearing pin and bolt, and bearing pin is main stressed member, spiral shell
Bolt simply plays a part of connection, is not involved in stress, and design is more reasonable, safety, positioning precision are high；One-time positioning is completed, scene
For group to convenient, fast, T-shaped connecting plate replaces original polylith lining plate structure, reduces the usage amount of steel plate, weight reduction, reduces into
This.Simple in construction, in amount of parts, all parts are all welded on girder, in the absence of Wrong, missing hair and field assembly position
Not to the problems such as, improve installation progress.
