Background technology
Air hammer air drilling is the boring method that percussion drilling and rotary drilling are combined, its operating principle is on bore bit, to connect special-purpose impactor, bore bit is on the basis of the pressure of the drill and torsional interaction, by impactor, to bore bit, applied the shock loading of certain frequency, under the synergy of bore bit impact grinding and rotation scraping, implement to creep into.For example, China Patent No. " CN200920106110.0 " discloses a kind of Three-wing-surface gauge air hammer drill, open day is on December 30th, 2009, mainly by bit body, heel teeth, flat tooth, gauge teeth, formed, in the bottom of bit body, be inlaid with flat tooth, periphery in bit body bottom is inlaid with heel teeth, and flat tooth and heel teeth are hemispherical hard alloy columnar teeths.On the taper surface of bit body front end, be evenly arranged the three Ge Denghu faces of cylinder, Three-wing-surface is inlaid with gauge teeth on Three-wing-surface.Gauge teeth is cylindrical hard-metal insert.Gauge teeth is evenly distributed on Three-wing-surface, and all the outer end of gauge teeth is on same periphery, and the center line of described periphery is the center line of bit body.
Air hammer air drilling is having very large advantage improving aspect bit speed, so air hammer air drilling obtained development rapidly in recent years, to matching equipment, requires more and more higher.When the operation of air hammer gas drilling, if bore bit does not connect firmly with impactor, in drilling process, probably cause the come off drilling failure in shaft bottom of bore bit.
At present, in air hammer gas drilling, the handling of bore bit adopt wirerope-winding bore bit, then with rig floor air winch, wire rope are strained, to retrain air hammer drill bit horizontal direction rotational freedom and displacement degree of freedom; With Type B clamp-buckle, live air hammer housing again, bore bit is loaded and unloaded.In cargo handling process, rotational freedom and displacement degree of freedom that wire rope and rig floor air winch can not Complete Bind bore bit horizontal directions, lay winding wire ropes that be repeatedly, causes the efficiency of loading and unloading of air hammer drill bit low; In cargo handling process, if moment of torsion too large (particularly when shackle) can cause fracture or the slippage of wire rope, cause serious security incident.
Summary of the invention
The purpose of this utility model is to overcome the problems referred to above that the handling of bore bit in existing air hammer gas drilling exist, a kind of gas drilling air hammer drill bit loading and unloading device is provided, the utility model can retrain rotational freedom and the displacement degree of freedom of bore bit horizontal direction efficiently, improves the efficiency of loading and unloading of air hammer drill bit and strengthens the safety that rig floor operates.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of gas drilling air hammer drill bit loading and unloading device, it is characterized in that: comprise base and stiffener, described base comprises clamp, on clamp, be provided with the latch that drop handle and pin-and-hole a plurality of and on rotating disk coordinate, and on clamp, be also provided with the bayonet socket and the card circle that coordinate with bore bit, stiffener is arranged on the open end sealing bayonet socket of bayonet socket.
Described latch is four, and four latch place circles are concentric with the card circle on clamp.
Described latch is weldingly fixed on clamp.
On described clamp, be provided with pin hole, stiffener is fixedly installed on clamp by connecting pin and pin hole.
The side that described stiffener is relative with card circle is provided with the arc section coordinating with bore bit.
Employing the utility model has the advantage of:
One, the utility model comprises base and stiffener, described base comprises clamp, on clamp, be provided with the latch that drop handle and pin-and-hole a plurality of and on rotating disk coordinate, and on clamp, be also provided with the bayonet socket and the card circle that coordinate with bore bit, stiffener is arranged on the open end sealing bayonet socket of bayonet socket, adopt this structure, by a plurality of latches, can retrain efficiently rotational freedom and the displacement degree of freedom of bore bit horizontal direction, by bayonet socket and card circle, fixedly bore bit be can retrain, the efficiency of loading and unloading of air hammer drill bit and the safety of reinforcement rig floor operation improved.
Two, in the utility model, described latch is four, and four latch place circles are concentric with the card circle on clamp, while adopting this structure, when fixed air hammer bore bit, can latch be inserted in rotating disk pin-and-hole very easily, during with the handling of Type B pincers, can guarantee that air hammer is placed in the middle, make its stress balance.
Three, in the utility model, described latch is weldingly fixed on clamp, adopts welding to guarantee the globality of latch and clamp, has further guaranteed the rotational freedom of constraint bore bit horizontal direction and the reliability of displacement degree of freedom.
Four, in the utility model, on described clamp, be provided with pin hole, stiffener is fixedly installed on clamp by connecting pin and pin hole, can rapidly stiffener be fixed on base by connecting pin, increase the torsional strength of loading and unloading device, guarantee the safety of rig floor operation simultaneously.
Five,, in the utility model, the side that described stiffener is relative with card circle is provided with the arc section coordinating with bore bit, adopt this structure when retraining bore bit, make stiffener and bayonet fittings tightr, retrain more reliable.
In sum, the utility model has been realized simple in structure, and cost is low, and convenient processing and manufacture and easy and simple to handle has improved the efficiency of loading and unloading and the safety guarantee of air hammer drill bit.
