Description
Technical field
The invention belongs to assembly fixture technical field, particularly relate to a kind of pot tending machine crane span structure assembly fixture.
Background technology
Pot tending machine is one of key equipment of aluminum industry the most processed large-scale pre-baked burning anode electrolysis factory, pot tending machine is also by two the most single beam bicycle structures, it is improved to big span three beam two bassinet structure, span is up to 33 meters, meet domestic and international large-scale aluminium electrolysis factory high-temperature molten salt, big electric current, high-intensity magnetic field, many dust and the working condition requirement of HF flue gas and technique to need.
Triple-beam structure multifunctional electrolytic machine group, main by cart, tool cart, go out aluminum dolly, hydraulic system, the part composition such as pneumatic system and electric-control system, cart is aluminum electrolysis multifunctional overhead crane tool cart, go out the gantry part of aluminum trolley travelling, cart is mainly by girder, end carriage, the parts such as wheel are constituted, it is structurally characterized in that cart is provided with three girders, girder is a kind of portable metal structure, it it is the main load bearing component structure of overhead traveling crane, the girder quality of large span overhead traveling crane accounts for the 50%～60% of complete machine deadweight, so reasonably determining structural parameters and the assembling form of girder, it it is the deadweight alleviating girder, prevent main beam deformation from causing tool cart, go out the key point of the inclined rail of aluminum dolly；It is provided with tool cart between two girders, goes out aluminum dolly, tool cart, go out aluminum dolly respectively with four wheel supportings on the track of girder, the core component of multifunctional electrolytic machine group is such as: crust breaker, cutting agency, more anode changing device, hydraulic means and control cabinl pulpit are all arranged on tool cart, and tool cart runs 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 assembling quality directly affect tool cart, go out the work operation conditions of aluminum dolly, for overhead traveling crane especially for big span, how to guarantee the perpendicularity between the depth of parallelism, girder and end carriage between every girder of the overhead traveling crane linearity in more than 30 meters of length, three girders, the linearity of linearity, the flatness of frame structure corner, high-altitude and wheel between two end carriages is the key issue restricting the assembling of current fast pace high efficiency overhead traveling crane.
Although have employed a lot of measures during overhead traveling crane crane span structure assembles in the past, for ensureing and realize the high-quality and high-efficiency of overhead traveling crane assembling, but owing to lacking special fixture, omnibearing control of overhead traveling crane crane span structure assembling is ensured, crane span structure assembling form and position tolerance it is difficult to ensure that, its assembling quality and efficiency of assembling the most significantly take on a new look, and there is potential safety hazard, as: 1, it is two conjoined cast steel part rectangle bases that the crane span structure assembling used in early days supports base, owing to understructure heaviness is difficult to carry, motility is very poor, simultaneously because the casting time is long, and cast structure exists casting trachoma, the drawbacks such as pore, after above the heaviest crane span structure of conducting oneself with dignity is put, easily crack at the uneven place of casting, base is caused to support cracking, potential safety hazard is serious；Simultaneously because linearity is difficult to ensure card between two end carriages, causing the depth of parallelism between girder, girder the most overproof with the perpendicularity of end carriage, the time that adjusts during assembling is long, inefficiency.
2, later steel-casting base Curve guide impeller is become several groups of special contour pads of Welding Structure form, after one end, contour pad surface positions with fixed block, end carriage is placed in above；The contour pad of this version is due to highly consistent, the frame structure of end carriage with girder is equipped with and has been obviously improved, simultaneously because contour pad one end has locating piece to limit, the linearity adjustment time of two end carriages substantially shortens, but the flatness of several groups of contour pads and the linearity put are required high by this structure, after end carriage assembling, the linearity of nearly 30 meters of length requires to be guaranteed in ± 0.03mm, adjust the most extremely difficult, assembling quality and efficiency of assembling are the most undesirable, to such an extent as to the girder in later stage is assembled impact very greatly, adjustment assembly efficiency is the lowest repeatedly.
