Description
[technical field]
The present invention relates to a kind of hoisting crane, especially relate to a kind of annular suspension double-beam crane.
[background technology]
Common ring-shaped crane is the crane in bridge type of top operation, and its work area only is that round track is with interior zone.In the prior art, hoisting crane only has a circular orbit, and the rotating speed of all cart wheels is identical, can adopt the traveling mechanism of the larger traveller of standard, and except the arc end carriage, all the other are same or similar to common crane in bridge type order.Common ring-shaped crane dolly and the height of girder increase the hoisting crane whole height, the factory building cost is higher, common ring-shaped crane also can't carry out the material handling work beyond the circular orbit, and the support post of circular orbit has affected the operation of land vehicle. can't satisfy client's specific demand.
At present, rotatable suspended beam crane is widely used in stacking, entrucking, the field such as unload of elongated steel of manufacturing line, steel warehouse, the harbour of steel rolling mill, is used for slab, round steel, square steel and other elongated steel of handling iron and steel material quality.In the prior art, rotatable suspended beam crane mainly contains top dolly rotary crane and two kinds of versions of bottom drop in beam rotary crane.Wherein: the top that the rotating mechanism of top dolly rotary crane and lifting mechanism are arranged on running trolley, Main Problems are that himself weight is large; The cart rail level is large to complete machine vertex size, has not only increased the factory building whole height, and has strengthened factory building investment construction cost; In addition, the circular orbit that this hoisting crane adopts also exists the processing and manufacturing difficulty, the shortcomings such as expense height.Another kind of bottom drop in beam rotary crane, compare with top dolly rotary crane, although its deadweight is lighter, because the rubber tyre gantry crane design structure is limit, the drop in beam that has determined the flexible suspension that it adopts can not have faster rotative speed, therefore exists the practical problemss such as production efficiency is lower.
At present double-beam hanging driving, large Car Track is two parallel orbits, the protection face of suspension hook is rectangle.But be difficult to satisfy technological requirement at circulating manufacturing line.Mostly the annular suspension duty twin beams of high request is imported product.Such as: the China that uses in the nuclear power nuclear island only has large rising to produce, and core component is import.It is asynchronous that domestic annular suspension twin beams exists two ends to drive more, and " gnawing the rail phenomenon " perhaps arranged.The problems such as accurate positioning difficulty is large.
[summary of the invention]
The technical matters that the present invention solves provide a kind ofly start steadily, the annular suspension double-beam crane of registration, reliable, reasonable in design, safety and stability
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of annular suspension double-beam crane, it is characterized in that, comprise two annular end carriages, be suspended on two carts on the annular end carriage, be used for the fixedly chopped-off head roof beam structure of cart, be installed in the girder on the chopped-off head roof beam structure, be suspended on the dolly on the girder, be arranged on the secondary roof beam structure on the dolly and be suspended on hoist ceiling crane on the secondary roof beam structure, described cart can be along the circumferential movement of two annular end carriages, described dolly can move along the length direction of girder, and described hoist ceiling crane can move along the length direction of secondary roof beam structure.
Preferably, the cross-sectional plane of described annular end carriage is " worker " font, and the wheel of described cart comprises many to wheels, and the wheel of every pair of wheels is suspended on respectively the left and right sides of " worker " font annular end carriage.
Preferably, the cross-sectional plane of described girder is " worker " font, and the wheel of described dolly comprises many to wheels, and the wheel of every pair of wheels is suspended on respectively the left and right sides of " worker " font girder.
Preferably, the cross-sectional plane of described secondary roof beam structure is " worker " font, and described hoist ceiling crane is equipped with one wheel pairs at least, and described wheel is suspended on the left and right sides of the secondary roof beam structure of " worker " font.
Preferably, the vertical described annular end carriage setting of described girder, the vertical described girder setting of described secondary roof beam structure.
The present invention's beneficial effect compared with prior art is: because cart is suspended on two annular end carriages, dolly is suspended on the girder of cart, hoist ceiling crane is suspended on the chopped-off head roof beam structure of dolly, cart can be along the circumferential movement of two annular end carriages, dolly can move along the length direction of girder, and hoist ceiling crane can move along the length direction of secondary roof beam structure.Structure of the present invention have starting steadily, the advantages such as registration, reliable, reasonable in design, safety and stability.
