Abstract
It the utility model is related to a kind of three wings reamer, including rotating part, the reamer being fixed on rotating part and the guiding driving section of connection rotating part and reamer, the rotating part includes connection square toes and is fixed on connection square toes and has the motion bar of internal thread hole, the reamer includes the steady rest being fixed on motion bar and three reaming wings being flexibly connected with steady rest, the driving section that is oriented to includes being fixed on swivel becket with the drilling rod of motion bar threaded connection and the swivel becket being flexibly connected with drilling rod, the reaming wing.The torsion of reaming is distributed on three reaming wings by the application, reduces the active force that the single reaming wing is born, so as to reduce the fault rate of reamer.
Description
Technical field
A kind of reamer is the utility model is related to, more particularly to a kind of three wings reamer.
Background technology
Reamer is mainly used in creeping into pile body or stake bottom expands.Existing reamer is mainly two wing structures, passes through two
The reaming wing shares the torsion of reaming, and its shortcoming is：During hard rock construction, during torsion is transmitted, it may appear that hard rock
The operating mode increased with interaction force moment of the reaming wing, under the operating mode, rigidity and intensity to the reaming wing are brought greatly
To challenge, being often in the presence of that reamer is twisted off in work progress can not salvage in stake, stake is not reached requirement when checking and accepting,
Cause man power and material's loss.
Utility model content
The purpose of this utility model is to provide a kind of three wings reamer, the torsion of reaming is distributed to three reaming wings
On, the active force that the single reaming wing is born is reduced, solves the problems, such as that reamer is twisted off in stake.
In order to solve the above problems, the utility model provides a kind of three wings reamer, including rotating part, is fixed in rotation
Reamer and the guiding driving section of connection rotating part and reamer in portion, the rotating part include connection square toes and are fixed in
Connect on square toes and the motion bar with internal thread hole, the reamer include being fixed in steady rest on motion bar and with stably
Three reaming wings that frame is flexibly connected, the guiding driving section include the drilling rod being threadedly coupled with motion bar and connected with drilling rod activity
The swivel becket connect, the reaming wing are fixed on swivel becket.
Further, the reaming wing includes the upper limb and bottom wing being flexibly connected, the upper limb stable connection frame, under described
The wing connects swivel becket.
Further, the swivel becket passes through bearing jointed rod.
Compared with prior art, there is following technique effect in the utility model：
The utility model provides a kind of three wings reamer, and the torsion of reaming is distributed on three reaming wings, reduces list
The active force that the individual reaming wing is born, so as to reduce the fault rate of reamer.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein：11st, square toes are connected, 12, motion bar, 211, transverse slat, 212, stringer board, 221, upper limb, 222, bottom wing, 31, bore
Bar, 32, swivel becket.
Embodiment
Below in conjunction with accompanying drawing, lift a specific embodiment and described in detail.
As shown in figure 1, a kind of three wings reamer, including rotating part, the reamer that is fixed on rotating part and connection rotation
Transfer part and the guiding driving section of reamer.Rotating part includes connection square toes 11 and is fixed on connection square toes 11 and has internal thread
The motion bar 12 in hole.Connection square toes 11 are used to connect rotary drilling rig, transfer torque to and are oriented to driving section.Motion bar 12 is away from even
The one end for connecing square toes 11 is provided with internal thread hole, and driving section is oriented to for connecting.The reamer includes being fixed on motion bar 12
Steady rest and three reaming wings being flexibly connected with steady rest.Steady rest welded by a transverse slat 211 and three stringer boards 212 and
It is fixed and through on motion bar 12 into, transverse slat 211 into dish type.One side of stringer board 212 is fixed on transverse slat 211, while fixed
On motion bar 12.Three installing zones respectively one reaming wing of connection is formed on transverse slat 211.Each reaming wing includes being rotatably connected
Upper limb 221 and bottom wing 222, wherein upper limb 221 is connected on the installing zone on transverse slat 211.It is described guiding driving section include with
The drilling rod 31 of the threaded connection of motion bar 12 and the swivel becket 32 being flexibly connected with drilling rod 31, the upper end of drilling rod 31 have external screw thread,
And it is connected with motion bar 12.Swivel becket 32 is by bearing jointed rod 31, the also affixed bottom wing 222 on swivel becket 32.
During construction, rotary drilling rig driving motion bar 12 rotates, and drives drilling rod 31 to move upwards, the He of upper limb 221 of the reaming wing
The angle formed between bottom wing 222 diminishes, so as to realize ream operation.
Disclosed above is only the specific embodiment of the application, but the application is not limited to this, any this area
Technical staff can think change, should all fall in the protection domain of the application.
