The debugging and detection of system.
In use, an above-mentioned energy saving blast furnace billet shears are respectively provided with as shown in figure 3, exporting for each steel billet, and
And in plane where hanging beam, one inspection platform 6 is set, it can be achieved that in equipment use to after the maintenance of equipment and oil pipe aging and
Shi Genghuan, and faulty equipment is carried out the operation such as to replace.
The technical solution of aforementioned present invention, has the advantage that
1, by using suspended structure, it can be achieved that the Fast Installation of overall mechanism and detachable, and without in steel billet
Concrete pedestal is made below track, reduces the set-up time of overall mechanism, save the cost.
2, it by the way that wheel to be disposed over, effectively prevent cutting scaling-off blocking track.Overcome previous console mode billet shears
Setting is on ground, and in orbit, the foreign matters such as scum will cause track block, and equipment is caused to be unable to operate normally for wheel setting
Problem.
3, walking oil cylinder is arranged above cutting mechanism, avoids corrosion caused by oil cylinder washes away for a long time in the prior art,
The problem of foreign matter (steel billet head) for preventing oil cylinder to be dropped simultaneously smashes.
4, walking track is arranged above cutting mechanism, field maintenance when equipment being facilitated to produce may be implemented simultaneously
Online replacement, saves time and cost.
5, it makes mechanical touching formula travel switch by oneself, all-sealed structure is used, it is possible to prevente effectively from high temperature water mist causes it
Influence, have waterproof and dustproof and anticorrosion and other effects.Solve in previous use process, travel switch be usually rely on into
Mouthful, Costco Wholesale is high, and simultaneously blow-by, and it is highly prone to the influence of water mist and is corroded, is not available under water environment,
It causes equipment malfunction to make, causes failure, the short problem of service life.
6, weighing hanging wheel uses the board-like fixed structure of bearing U-shaped card, realizes wheel, the fast quick-detach of axis and replacement.Solve mesh
Preceding equipment all uses shaft-penetrating type structure, and when replacement need to first release the weight of load, needs to remove one by one, causes complex procedures, nothing
Method realizes the problem of online replacement.
7, hydraulic oil pipe tie point is guided to the top of overall mechanism, is avoided by building inspection platform (as shown in Figure 3)
, it can be achieved that the timely replacement after the maintenance of equipment and oil pipe aging in equipment use, solving oil pipe aging must shut down high temperature
The problem of a few hours could be replaced.
8, by the way that the vulnerable parts such as tool apron, sliding rail are changed to buckle-type mounting means, the replacement than conventional screw fastening-type is imitated
Rate improves 10 times or more, solves the problems, such as that screw gets rusty or erosion corrosion can not screw out easily.
In conjunction with attached drawing, the embodiments of the present invention are described in detail above, but the present invention is not limited to described implementations
Mode.For a person skilled in the art, in the case where not departing from the principle of the invention and spirit, to these embodiments
A variety of change, modification, replacement and modification are carried out, are still fallen in protection scope of the present invention.
