Description
Technical field
Single-beam crane, more particularly to a kind of monoblock type list main beam structure are the utility model is related to, is suitable for bridge-type, door
The crane girders such as formula.
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 monoblock type list main beam structure, design novel integral list main beam structure type
Formula 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.
Utility model content
In view of above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of monoblock type list main beam structure,
Reduce stock's specification of sheet material and section bar.
In order to solve the above technical problems, the utility model includes：
A kind of monoblock type list main beam structure, wherein, the monoblock type list main beam structure is by upper cover plate, lower cover and truss structure

Described monoblock type list main beam structure, wherein, above-mentioned truss is by rectangular tube, square tube, channel-section steel, angle steel, H profile steel, weldering
The shaped steel splicing group weldering such as steel pipe, I-steel or round steel is connect to form.
A kind of monoblock type list main beam structure provided by the utility model, reduces stock's specification of sheet material and section bar, can
Make monoblock type list main beam structure fast transportation and quick assembling, and use the frame mode of alignment pin and positioning shaft sleeve,
After monoblock type list main beam structure assembles be alignment pin and positioning shaft sleeve is main stressed member, ensure that monoblock type list girder
Intensity after Standard.Due to being spliced using section bar, older box-type structure fabrication is simple, fast；Reduce welding
Supply and demand, reduce wlding usage amount；Do not limited by order, girder " modular unit " can be subjected to running stock；Due to truss
Girder is spliced using shaped steel, and steel utilization ratio is high, improves corporate profit, and in outdoor application, can be ignored
The influence of wind load.Using " modular unit " design, girder only select several specifications " modular unit " can tonnage and
Span all standing, reduce stock's specification of sheet material and section bar；Because the crane main screw lift of truss reduces, along with girder is adopted
With " modular unit " design, land transport vehicle not acceptor's beam length limit, can more crane gears with car transport, reduce
Cost of transportation；Using fabricated structure, girder point " modular unit " makes, and can improve factory building utilization rate.When girder makes
Do not limited by the crane load in factory building, the cooperation of large-tonnage crane gear need not be installed in factory building and manufactured, reduced
Energy consumption, the connection between " modular unit " are attached using bearing pin and bolt, and bearing pin is main stressed member, and bolt is
To the effect of connection, stress is not involved in, design is more reasonable, safety, positioning precision are high；One-time positioning is completed, field assembly convenience,
Fast, T-shaped connecting plate replaces original polylith lining plate structure, reduces the usage amount of steel plate, weight reduction, reduces cost.Structure letter
Single, in amount of parts, all parts are all welded on girder, and in the absence of Wrong, missing hair and field assembly position is not reciprocity asks
Topic, improve installation progress.
