Description
Technical field
The utility model is related to steel bridge drilling crack arrest recovery technique fields, are related to a kind of angle for boring stop hole for real bridge
Control device.
Background technology
Orthotropic Steel Bridge Deck by torsional rigidity is big, intensity is high, from heavy and light, good integrity the advantages that, extensive use
In the construction of Large Span Bridges.But with the increase of bridge Years Of Service, Orthotropic Steel Bridge Deck problem of Cracking is increasingly tight
It is high, at the attachment weld of especially various structure details.For make bridge structure remain to maintain the operation phase safe condition, at present compared with
It is to take interim crack arrester for widespread practice, i.e., stop hole is drilled in crack tip using drilling machine, when crackle is further
After extension, then using other technologies means fatigue crack is further repaired.
But since local structure is complicated, operating space is limited in real bridge, is mostly actually to bore crack arrest the problems such as looking up operation
It is difficult to control bore angle during hole, often will appear bore angle bias phenomenon.Unsuitable bore angle can not have
The further cracking of delay fatigue crackle is imitated, What is more may cause new fatigue crack.In addition, working as bore angle
When deviation, less serious case can make drill bit stuck, and drill rod breaking, the drilling rod of fracture can be caused quickly to fly out and can very likely accidentally injure when serious
Operating personnel.
Utility model content
Goal of the invention：The utility model provides a kind of angle controller boring stop hole for real bridge, the device solution
Practical brill stop hole of having determined is difficult to control bore angle in the process, the problem of bore angle deviation occurs and drilling rod flies out and accidentally injures behaviour

Iron can be adsorbed on the top plate and U rib plate of steel bridge deck；When the magnetic base, which switchs, closes, the upper plate is under
The magnetic of bottom plate disappears, and the fixed support unit can be removed.
The sleeve both ends offer respectively with first sliding rail and the matched the first sliding groove of the second sliding rail shape and second
Sliding slot, and be slidably connected by fixing clip and bolt；Angle controller can slide between the first sliding rail and the second sliding rail,
Form different bore angles.The bolt is screwed, the fixing clip will be by first sliding rail and the sliding sleeve
Cylinder tightly fits together, to ensure that bore angle is not in change in boring procedure.
The guide sleeve both sides are respectively equipped with gib block, and are offered in the fixed plate matched with the guiding bar shaped
Guide groove, and can be slided along the gib block.When drilling, the hand drill is by the guide groove in the fixed plate along institute
Gib block advance is stated, passes through the guiding role of the guide sleeve and the guide groove, it is ensured that the hand drill is always towards certain
One fixed boring direction, avoids boring direction from deviation occur.
Support plate is equipped between the upper plate and lower plate.Support plate is used to fix the opposite position of upper plate and lower plate
It sets, three forms the monnolithic case frame of the fixed support body system.
Advantageous effect：1, the utility model, which realizes, meets the need that difference is drilled with crack arrest orifice angle when repairing steel box-girder crackle
It wants；2, by the guiding role of guide sleeve and guide groove, ensure that hand drill always towards a certain fixed boring direction, can avoid boring
There is deviation in hole direction；3, ensure that drilling fltting speed maintains at the uniform velocity state, and can be to avoid top plate be punched when, hand drill loses suddenly
It goes to balance, causes the secondary destruction of other structures；It 4, can be to avoid the iron generated when drilling by the adsorption effect of permanent-magnetic plate
The sundries such as bits are flown upward everywhere, reduce the on-site cleanup work amount after drilling.
