Technical field
The utility model relates to a kind of engineering machinery roller drill, particularly for the detachable quick-changing type engineering roller bit of rotary drilling rig.
Background technology
Generally using to revolve in pile foundation engineering field and dig stake, when excavating hardpan, needing to use roller drill.Roller drill generally includes drilling pipe and rock bit.Rock bit in the roller drill of current use is substantially all reclaim the tricone bit of second-hand oil drilling.Due to tricone bit three-wheel one, need to be divided into monomer to it, then be welded on churning driven cylinder.And the roller drill result of use of this structure is very undesirable, there is following shortcomings:
1, because tricone bit is divided into monomer to be welded to after in drilling pipe, rock bit assembling form changes, and hole end moulding, broken rock distribute and all revolutionize, and therefore, cause efficiency of breaking rock extremely low.
2, splitting, welding time, be easy to cause damage to the sealing of rock bit and Fuel Tanking Unit, thus reduce the application life of rock bit.
3, this rock bit used that reclaims does not have assembling base plane, and cannot ensure welding position requirement, the axiality of each gear wheel of the roller drill welded, tolerance of the high end all cannot reach technical requirements.
4, it is chronic that its combination assembling of the drilling tool recycled is carried out welding, and a bench drill machine at least needs two drilling tool rotations, and one uses on rig, and one is being changed rock bit.Often the time of a drilling tool welding rock bit exceedes the time in its application life, causes to shut down and waits for that situation about installing and using changed by drilling tool, thus reduce efficiency of construction.
5, drilling pipe frequent cutting, welding rock bit, be not only waste time and energy, go back the application life of serious curtailment drilling pipe.
Utility model content
Technical problem to be solved in the utility model is, the roller drill of rotary drilling rig generally includes drilling pipe and rock bit, according to the requirement of rotary drilling rig construction to drilling tool, a kind of detachable quick-changing type engineering roller bit is provided, with solve rotary drilling rig at present roller drill exist shortcomings, thus improve the operating efficiency of rotary drilling rig, reduce construction cost.
For achieving the above object, the utility model by the following technical solutions.Detachable quick-changing type engineering roller bit, comprise gear claw body, one end of gear claw body is connected with cone body, the gear claw body other end is connected with tooth pawl seat, and drift is equipped with in the side of gear claw body, opposite side has been bolted eccentric wheel, and door is equipped with in the side of tooth pawl seat, be provided with opening between door and tooth pawl seat, the eccentric wheel clamp that gear claw body opposite side is equipped with is loaded in opening.
Described drift is left and right part, and two relative plane parallel of drift, the one side of another two opposite faces is the first wedge inclined-plane, and another side is the second wedge inclined-plane.
First wedge inclined-plane of described drift and the wedge surface of tooth pawl seat draw-in groove match, the slopes which match of the second wedge inclined-plane 42 and gear claw body boss.
Detachable quick-changing type engineering roller bit, comprise tooth pawl seat, gear claw body, cone body three sections fit form, tooth pawl seat is welded in drilling pipe, cone body is assemblied on gear claw body axle journal, gear claw body inserts in the draw-in groove of tooth pawl seat, compress with two pieces of drifts and eliminate fit-up gap, pinning gear claw body with two eccentric wheels, prevent gear claw body from coming off from tooth pawl seat.Tooth pawl seat has been welded in drilling pipe when dispatching from the factory, ensure that status requirement; Tooth pawl seat and gear claw body have two datums of fitting when assembling, and datum A ensures the axiality of gear wheel on drilling tool, ensures the internal-and external diameter of cutting hole, and datum B ensures gear wheel height tolerance.
The utility model structure is simple, simple installation, position is accurate, efficiency of breaking rock is high.Which ensure that the requirement of installation site, ensured hole end moulding, broken rock amount homogenizing, controlled minimizing of cutting ring.Avoid the welding of gear claw body, protect sealing system and be not damaged, extend the application life of rock bit.In rock bit wearing and tearing or after damaging, more convenient during replacing, quick, configure two drilling tools without the need to a machine.Tooth pawl seat is fixed, and after changing rock bit, installation site can not change, not high to the technical requirements of operating personnel, can not affect precision and the stock-removing efficiency of roller drill.Eliminate gap after tooth pawl seat and gear claw body assemble, one-tenth is rigidly connected, and protecting tooth pawl seat can not impact damage, and namely extends the application life of roller drill.
