Description
Technical field
Double girder wherein equipment are the utility model is related to, more particularly to it is a kind of suitable for double girder bridge-types, gantry crane
And the double main beam structures of monoblock type of other crane gears.
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 main beam structure, design new main beam structure pattern and mount scheme, drop
Low cost of transportation, shortening is manufactured, the in-site installation cycle.
Because former double girder lifting device girders of the prior art use steel plate assembly welding shaping, girder is conducted oneself with dignity larger.It is double
When girder crane gear is used for outdoor, the influence of wind load is considered when calculating cart operation power of motor, when crane
When span is larger, because being limited by transport, it is necessary to disintegrate to girder, complexity is not only made at disintegration, also compare expense during installation
When.When double girder crane gears export, because the size of subject container limits, very big be stranded is brought for old-fashioned structure
It is difficult.Need to carry out bulk delivery, sea-freight can corrode lacquer painting, influence crane gear quality, while ocean freight in bulk is very
It is high.Double girders are influenceed by tonnage and span, and the section of girder and structure type are more, are made cumbersome.Factory needs to carry out sheet material
Library storage it is standby, the utilization rate of sheet material is not high, produce waste.Acceptor's beam length limits, and separate unit haulage vehicle can not more liftings
Equipment transport simultaneously, and cost of transportation is high.When girder is longer, hall space is required, place is too small to be given birth to
Production makes.Box girder heavier-weight, when tonnage, span are larger, the lifting capacity of the crane in factory building is required, tonnage
It is too small to be manufactured.Former girder disintegration joint is two pieces of flanges of welding at disintegration, is matched somebody with somebody in ring flange surrounding
Bore, scene is attached by bolt.In the inside and outside lining plate of girder, inside and outside liner plate and girder web plate, upper and lower cover plate are carried out
With brill, hand hole is opened on girder web plate, is attached by bolt.Bolt is main stressed member.Multi-sheets are needed to be matched somebody with somebody
Bore, make cumbersome, fabrication cycle length, and only bolt connection, assembly precision is low during in-site installation, influences product quality, only
It is inconvenient using multiple bolt connections, in-site installation.Trolley travelling track needs scene to be welded, and influences the outer of crane gear
Appearance quality.
Therefore, prior art needs further improvement and developed.
