Invention content
The purpose of the present invention is to provide a kind of reaming helicoid hydraulic motor devices, to overcome existing drilling-in unit because of underpower
The shortcomings that can not completing the reaming task of big hole milling diameter.
To achieve the above object, the present invention provides a kind of reaming helicoid hydraulic motor device, to the hole milling to no-dig technique into
Row reaming, reaming helicoid hydraulic motor device include：Helicoid hydraulic motor, broaching support frame, reaming bit and preceding centralizer.Reaming supports
The threaded upper ends of frame rear end and helicoid hydraulic motor connect；The nose threads of reaming bit and helicoid hydraulic motor connect, and reaming bit is used
To carry out reaming to hole milling, to be big hole milling by hole milling reaming；And the nose threads of preceding centralizer and broaching support frame connect
It connects, and preceding centralizer carries out righting to stretch into hole milling to broaching support frame, reaming bit and helicoid hydraulic motor；Wherein, screw rod
Required torque and rotating speed when drilling tool is to provide reaming bit broken rock, to enable reaming bit to carry out rotation；Wherein,
The rotating speed that broaching support frame can provide helicoid hydraulic motor is converted to the revolution of reaming bit, and then enables reaming bit with big
Hole milling is that axle center is revolved round the sun.
Preferably, in above-mentioned technical proposal, helicoid hydraulic motor is the larger helicoid hydraulic motor of camber.
Preferably, in above-mentioned technical proposal, preceding centralizer can be to meet the drill bit of size, and helicoid hydraulic motor can be by drilling machine
Centralizer carries out rotation before the torque and rotating speed of generation are driven by broaching support frame.
Compared with prior art, the present invention has the advantages that：The reaming helicoid hydraulic motor device of the present invention, structure letter
Single reasonable, reaming bit can complete rotation but also be revolved round the sun as axle center using big hole milling, can be complete to realize drilling-in unit
At the reaming task of large aperture.
Description of the drawings
Fig. 1 is the structural schematic diagram of reaming helicoid hydraulic motor device according to the present invention.
Main appended drawing reference explanation：
Centralizer before 1-, 2- broaching support frames, 3- reaming bits, 4- helicoid hydraulic motors.
Specific implementation mode
Below in conjunction with the accompanying drawings, the specific implementation mode of the present invention is described in detail, it is to be understood that the guarantor of the present invention
Shield range is not restricted by specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " comprising " or its change
It changes such as "comprising" or " including " etc. and will be understood to comprise stated element or component, and do not exclude other members
Part or other component parts.
As shown in Figure 1, Fig. 1 is the structural schematic diagram of reaming helicoid hydraulic motor device according to the present invention, had according to the present invention
A kind of reaming helicoid hydraulic motor device of body embodiment, to carry out reaming, reaming helicoid hydraulic motor device to the hole milling of no-dig technique
Including：Helicoid hydraulic motor 4, broaching support frame 2, reaming bit 3 and preceding centralizer 1.2 rear end of broaching support frame and helicoid hydraulic motor 4
Threaded upper ends connection；Reaming bit 3 is connect with the nose threads of helicoid hydraulic motor 4, and reaming bit 3 is expanding hole milling
Hole, to be big hole milling by hole milling reaming；And preceding centralizer 1 is connect with the nose threads of broaching support frame 2, and preceding centralizer
1 carries out righting to stretch into hole milling to broaching support frame 2, reaming bit 3 and helicoid hydraulic motor 4；Wherein, helicoid hydraulic motor 4 to
Required torque and rotating speed when 3 broken rock of reaming bit are provided, to enable reaming bit 3 to carry out rotation；Wherein, reaming branch
The rotating speed that helicoid hydraulic motor 4 provides can be converted to the revolution of reaming bit 3 by support 2, and then enable reaming bit 3 with big milling
Hole is that axle center is revolved round the sun.
Preferably, helicoid hydraulic motor 4 is the larger helicoid hydraulic motor of camber, so as to preferably make reaming bit 3 carry out reaming；
Preceding centralizer 1 has drill bit, and helicoid hydraulic motor 4 can drive the drill bit of centralizer to carry out rotation by broaching support frame 2.
In practical applications, preceding centralizer 1 is first positioned in hole milling by operating personnel, opens helicoid hydraulic motor 4, screw rod at this time
Drilling tool 4 drives reaming bit 3 to carry out rotation, while the torque and rotating speed that drilling machine provides can be passed to reaming by helicoid hydraulic motor 4
Supporting rack 2, and then pass to preceding centralizer 1 so that broaching support frame 2 and preceding centralizer 1 carry out rotation, and broaching support frame
2 are converted to the rotating speed that helicoid hydraulic motor 4 provides the revolution of reaming bit 3, to make reaming bit 3 not only can may be used also with rotation
It is revolved round the sun with the axle center with big hole milling, reaming bit 3 can carry out ream operation to hole milling at this time, and reaming bit 3 touches
When rock around hole milling, 3 rotation of reaming bit adds revolution, so as to be that (big hole milling is hole milling to big hole milling by hole milling reaming
1.5 times to 1.8 times).
And preceding centralizer 1 reaming bit 3 to hole milling carry out reaming while, preceding centralizer 1 is in hole milling to screw drill
Tool 4, broaching support frame 2 and reaming bit 3 carry out righting, caused by preventing when reaming because of the reason of the gravity reaming move down.
In short, the present invention reaming helicoid hydraulic motor device, it is simple and reasonable, reaming bit can complete rotation but also with
Big hole milling is that axle center is revolved round the sun, and the reaming task of large aperture can be completed to realize drilling-in unit.
