Description
Technical field
the invention belongs to assembly fixture technical field, relate in particular to a kind of pot tending machine crane span structure assembly fixture.
Background technology
pot tending machine is one of key equipment of the large-scale pre-baked burning anode electrolysis of aluminium industry processed factory both at home and abroad, pot tending machine is also by original two single beam bicycle structures, be improved to large span three beam two bassinet structures, span can reach 33 meters, met domestic and international large-scale aluminium electrolysis factory high-temperature molten salt, working condition requirement and the technique of large electric current, high-intensity magnetic field, many dust and HF flue gas need.
three girder construction multifunctional electrolytic machine groups, mainly by cart, tool cart, go out aluminium dolly, hydraulic system, the part such as pneumatic system and electric-control system composition, cart is aluminum electrolysis multifunctional overhead crane tool cart, go out the crane span structure part of aluminium trolley travelling, cart is mainly by girder, end carriage, the parts such as wheel form, its design feature is that cart is provided with three girders, girder is a kind of portable metal structure, it is the main load bearing component structure of overhead traveling crane, the girder quality of large span overhead traveling crane accounts for 50%～60% of complete machine deadweight, so reasonably determine structural parameters and the assembling form of girder, it is the deadweight that alleviates girder, prevent that main beam deformation from causing tool cart, go out the key point of the inclined to one side rail of aluminium dolly, between two girders, be provided with tool cart, go out aluminium dolly, tool cart, go out aluminium dolly respectively with four wheel supportings on the track of girder, the core component of multifunctional electrolytic machine group as: crust breaker, cutting agency, more anode changing device, hydraulic means and control cabinl pulpit are all arranged on tool cart, and tool cart moves and realize the actions such as crust breaking, blanking, anode change on cart.
as can be seen here, the crudy of overhead traveling crane crane span structure and assembly quality directly affect tool cart, go out the work operation conditions of aluminium dolly, particularly for the overhead traveling crane of large span, the flatness that perpendicularity, the linearity between two end carriages, high-altitude frame structure between the depth of parallelism, girder and end carriage between linearity, three girders of every girder how guaranteeing overhead traveling crane in more than 30 meters of length are four jiaos and the linearity of wheel are the key issues of the current fast pace high efficiency overhead traveling crane assembling of restriction.
although adopted a lot of measures in overhead traveling crane crane span structure assembling process in the past, for ensureing and realize the high-quality and high-efficiency of overhead traveling crane assembling, but owing to lacking special fixture, overhead traveling crane crane span structure is assembled to omnibearing control guarantee, the form and position tolerance of crane span structure assembling is difficult to ensure, its assembly quality and efficiency of assembling never significantly take on a new look, and there is potential safety hazard, as: 1, the early stage crane span structure assembling base for supporting adopting is two conjoined cast steel part rectangle bases, because understructure heaviness is difficult to carrying, flexibility is very poor, simultaneously because the casting time is long, and in cast structure, there is casting trachoma, the drawbacks such as pore, after above the very heavy crane span structure of deadweight is put, very easily crack at the inhomogeneous place of casting, cause base to support cracking, potential safety hazard is serious, simultaneously, because linearity between two end carriages is difficult to ensure card, cause the perpendicularity of the depth of parallelism between girder, girder and end carriage seriously overproof, when assembling the adjustment time long, inefficiency.
2, afterwards steel-casting base is improved to several groups of special contour pads that are designed to Welding Structure form, after locate with fixed block one end, contour pad surface, above end carriage is placed in; The contour pad of this version is due to highly consistent, the frame structure of end carriage and girder has been equipped with to obvious improvement, simultaneously because there is locating piece restriction contour pad one end, the linearity adjustment time of two end carriages obviously shortens, but the flatness of this structure to several groups of contour pads and the linearity of putting require high, after end carriage assembling, the linearity of nearly 30 meters of length requires to ensure at ± 0.03mm, adjust still quite difficult, assembly quality and efficiency of assembling are still very undesirable, to such an extent as to very large on the girder assembling impact in later stage, adjustment assembly efficiency is very low repeatedly.
