Description

The angle controller of stop hole is bored for real bridge
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 The problem of making personnel, while reducing the workload of scene cleaning.
Technical solution:The angle controller that stop hole is bored for real bridge of the utility model, including fixed support unit, Angle control unit, pilot unit and hand drill unit.
The fixed support unit includes permanent-magnetic plate, and the permanent-magnetic plate is equipped with the through-hole worn for drill bit, and institute The two opposite sides side for stating permanent-magnetic plate is connected separately with the upper plate and lower plate contradicted with bridge floor, the upper plate and lower plate Between be equipped with arc the first sliding rail and the second sliding rail;Permanent-magnetic plate is one piece of iron plate with permanent magnetism, and it acts as suctions The sundries such as the iron filings generated when attached drilling reduce the on-site cleanup work amount after drilling.
The angle control unit includes sliding sleeve, and the sliding sleeve both ends respectively with first sliding rail and Two sliding rails are slidably connected, for determining bore angle.
The pilot unit includes guide sleeve, and the guide sleeve is connect with the sliding sleeve, and is used for pilot bore hole side To.
The hand drill unit includes hand-held part, drill bit and the fixed plate being socketed with the drill bit, and passes through fixed plate and institute Guide sleeve is stated to be slidably connected.
Fixed support body system supports by the way that upper and lower bottom plate and bridge deck structure are inconsistent to fix, and then angle is utilized to control Sliding sleeve in device is slidably connected with the first and second sliding rail, determines that bore angle, guide sleeve guide advance when hand drill drilling Direction avoids the occurrence of and trains off.
Hand drill unexpected disequilibrium control when drilling when avoiding punching, which further includes buffer cell, and the buffering is single Member includes the buffer stopper being connect with the guide sleeve, is equipped with gas chamber in the buffer stopper and is equipped with mobile piston, and described slow It rushes block and offers the stomata being externally vented, wherein the mobile piston contradicts with the fixed plate and can be with fixed plate It pushes and moves.The buffer stopper is equipped with 4, and is connected to that 4 sides of the guide sleeve open up and coordinates with its shape Card slot in.
When drilling, the end thereof contacts of fixed plate and mobile piston, and with the propulsion of boring procedure, fixed plate constantly pushes Mobile piston, the gas in gas chamber are squeezed by mobile piston, are discharged by stomata, due to the air vent aperture very little, It can guarantee that fltting speed maintains at the uniform velocity state.When drilling drills component, hand drill loses the inhibition power of component, fltting speed Increase suddenly in a flash, due to air vent aperture very little, the gas in gas chamber can not be discharged rapidly and rapidly be compressed, and form one A inhibition power, the inhibition power of alternative means avoid other components of bit hits to slow down hand drill fltting speed, Cause secondary destruction.
Further to realize that the stability of fixed support, the fixed support unit are equipped with control upper plate and lower plate Magnetic magnetic base switch.When the magnetic base, which switchs, to be opened, the upper plate shows as one block of magnetic with lower plate 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.
