Description
Technical field
The invention belongs to bridge inspection and maintenance technical field, is related to a kind of steel box-girder crack forming mechanism drilling of energy keyhole depth
Machine.
Background technology
Steel box-girder itself have the advantages that torsional rigidity is big, intensity is high, from heavy and light, good integrity, therefore in bridge construction
In obtain extensive promote and application.But with the increase of bridge Years Of Service, steel box-girder problem of Cracking is increasingly serious, especially
At the attachment weld of various structure details.It is more universal at present to make bridge structure remain to maintain the safe condition of operation phase
Way is to take interim crack arrester, i.e., is drilled with stop hole in crack tip using drilling machine, after crackle further expands, then
Fatigue crack is further repaired using other technologies means.
In order to overcome the human error of bore position and angle, inventor was preceding proposing one kind for steel box-girder drilling
The electric hand drill location aid device of crack arrest, number of patent application 2017204116398.But all types of steel plateelements for forming steel box-girder are thick
Spend relatively thin, the steel plateelement of cracking position easily punched when being drilled with stop hole using regular drills, What is more can wear by mistake it is neighbouring
Without the steel plateelement of perforate, structural damage is caused.Such as at steel box-girder top plate and U rib attachment welds, the usual edge of crackle at this
Weld seam development, when carrying out crack arrest hole operation using regular drills, operating personnel can not grasp drilling depth, can only rely on sense
Feel and carry out operation, the phenomenon for wearing steel box-girder top plate by mistake often occurs, causes top plate to damage, causes new crackle, further threaten
Bridge security.
In addition, correlative study shows, the different influence degrees to suppressing Crack Extension of drilling depth have considerable influence,
And drilling depth is limited by steel plateelement thickness.Need to use different drilling depths for different steel plateelements, and current
Regular drills can not realize accurate this target of keyhole depth.
Therefore, it is necessary to a kind of brand-new steel box-girder crack forming mechanism drilling machine that can control brill crack arrest hole depth be designed, with solution
Certainly above mentioned problem.
The content of the invention
