Description
Technical field
The utility model belongs to boring mechanic and manufactures and designs field, especially belongs to a kind of reamer with Telescopic.
Background technology
In building, bridge and other engineering construction, usually relate to the problem strengthening anchoring stability, due to the development of highrise building, speedway, high-speed railway, viaduct, require also more and more higher to the supporting capacity of ground.At present a large amount of friction pile adopted comprises: castinplace pile, draw anchoring pile, post etc., and the frictional force of pile body and ground determines the supporting capacity of pile body.For addressing this problem, at present having developed not isometrical castinplace pile in construction, having drawn anchoring pile, column method, namely at castinplace pile, draw in the buried ground of anchoring pile, post and adopt reducing hole, utilize reducing hole and the larger frictional force of ground to strengthen anchoring stability.The contact area of adhesives and hole wall can be expanded after reaming, after reaming, greatly can improve anchored force.
Current various foundation pouring stake holes, draw anchoring pile hole usually to adopt drilling method, datum hole adopts segmentation reaming realize reducing.Segmentation reaming completes realization by reamer, and existing reamer kind is more, and many employing reaming bite Collapsible structures, Telescopic is realized by pull bar.
Summary of the invention
The utility model discloses a kind of anchoring-bolt broaching drill bit according to the deficiencies in the prior art.Problem to be solved in the utility model is to provide one and can realizes reaming, creep into reaming, automatic soil-discharging, can realize the flexible anchoring-bolt broaching drill bit of reaming bite without the need to pull bar.
The utility model provides following technical scheme to realize:
A kind of anchoring-bolt broaching drill bit, comprise Drilling bore bit, it is characterized in that: described Drilling bore bit is connected with supporting seat, the symmetrical both sides of supporting seat and crank connecting link bearizing mechanism handle of a knife hinged, both sides crank connecting link bearizing mechanism is also hinged with support slide, support slide and supporting slider are slidably matched, and described supporting slider is set with the back-moving spring driving and support slide rebound reset, has the square hole inserting when gliding with supporting slider and coordinate in the middle part of Drilling bore bit.
Described crank connecting link bearizing mechanism comprises the flank handle of a knife and bottom wing handle of a knife that are hinged, and bottom wing handle of a knife outer rim is welded with pricker sheet.
There are the water delivery or gas transmission through hole that are communicated with drilling rod in described supporting seat and supporting slider center.
When anchoring-bolt broaching is drilled in free state, linkage is subject to the reaction force of back-moving spring compressive force, and crank connecting link bearizing mechanism is in contraction state.When datum hole put into by reamer, Drilling bore bit withstands bottom datum hole, then pressurizes, and supports the pressure that slide overcomes back-moving spring, make support slide slide downward, the flank handle of a knife of crank connecting link bearizing mechanism and bottom wing handle of a knife are stretched out, the handle of a knife outer rim of bottom wing handle of a knife is welded with pricker sheet, bit, pricker sheet cutting ground, continuous pressurization, rotates, creeps into, and reaches reaming effect.
When sliding bar is to certain position, supporting slider bottom square to be inserted in Drilling bore bit square hole and is driven Drilling bore bit to start to rotate, and realizes creeping into, one side reaming.In drilling process, provide compressed air or water under high pressure to drill bit, by through hole to drill bit bottom compression contracting air or water under high pressure, dregs is gone out, realize casting function.
The utility model helpfulness: the utility model adopts crank connecting link bearizing mechanism and Drilling bore bit to form anchoring-bolt broaching and bores, crank connecting link bearizing mechanism support bar arranges back-moving spring makes flank handle of a knife and bottom wing handle of a knife facilitate, and can realize reaming bite to stretch operation without the need to pull bar; And can need to carry out independent reaming or creep into the operation with reaming operation simultaneously according to creeping into, dregs to drill bit bottom compression contracting air or water under high pressure, can be gone out, realizes casting function by bit central through hole.
