Specific embodiment
The main thought of the present invention, is in drillng operation to install this instrument in BHA, using highly pressurised liquid
Realize that the reciprocating motion of tup causes impact loading rotation to be realized in drill bit and impact composite breaking rock stratum as power.It is logical
The description below to embodiment is crossed, will more contribute to the public understanding present invention, but can't be by given by applicant
Specific embodiment be considered as the restriction to technical solution of the present invention, any definition to part or technical characteristic is changed
And/or make form to overall structure and immaterial conversion is regarded as the protection model limited by technical scheme
Enclose.
Hydraulic impacter as shown in Figures 1 to 6, the hydraulic impacter include striker 1, drive sleeve 2, shell 3, guiding
Set 4, Hammer head assembly 5, rotating body component 6, turbine assembly 7, joint 8, high-velocity fluid are flowed in impacter, first from joint 8
Into in turbine assembly 7, the kinetic energy of high-velocity fluid is converted into turbine the kinetic energy in rotary motion direction, is connected to whirlpool so as to drive
The rotation of the rotating body component 6 on wheel assembly 7, has several thrust ball bearing strings to ensure turbine assembly rotation inside turbine assembly 7
That what is moved is smooth.Joint 8 is connected with turbine assembly 7, and turbine assembly 7 is connected with rotating body component 6 by power transmission shaft, rotary body group
Hammer head assembly 5 is set with part 6, Hammer head assembly 5 can be along the axis direction of hydraulic impacter under the drive of rotating body component 6
Move reciprocatingly, when do under drive of the rotating body component 6 in turbine assembly 7 from axle rotate when, the top of Hammer head assembly 5 being capable of shape
Into variable spaces a, high-velocity fluid is entered in variable spaces a and is pressurized by compression, is the savings energy that Hammer head assembly 5 provides downward impact
Amount.One end of fairlead 4 is provided with guide post, and 5 corresponding one end of Hammer head assembly is provided with the gathering sill matched with guide post, is led
Cooperate to bar and gathering sill, limit the motion that rotates in a circumferential direction of Hammer head assembly 5, so as to allow the Hammer head assembly 5 can only be along axle
Line moves reciprocatingly.Four holes, the central through hole of power transmission shaft and four holes are opened in the transmission shaft turbine lower end of turbine assembly 7
Connect with lower flow passage.Turbine assembly 7 is distributed 1～50 grade along axis, and every grade of turbine is all made up of stator and rotor.Turbine assembly
7 upper and lower side is respectively provided with for reducing the wavy spring packing ring that impact is produced in turbine rotation, is additionally provided with wavy spring stroke
Position limitation protection ring.
When under free state, (when i.e. the hydraulic impacter is in bottom) Hammer head assembly 5 is in against 4 side of fairlead,
When have in drilling rod have highly pressurised liquid to flow through turbine assembly 7 when, turbine is produced and is rotated at a high speed, and body component is rotated by power transmission shaft
6 rotate at a high speed, and rotating body component 6 is screw joining manner (similar to thread connecting mode) with the connected mode of Hammer head assembly 5,
Due to the annexation that the gathering sill c of tup is only in axial direction moved with fairlead lead column d composition, i.e. Hammer head assembly 5
Can only move reciprocatingly and can not rotate, so that Hammer head assembly 5 can only be moved back and forth along axis, so as to work as rotary body
Hammer head assembly 5 is driven to move when component 6 rotates upwards, when Hammer head assembly 5 rises to a setting height (2～50mm), tup group
Part 5 is the fluid compression supercharging in rotating body component during lifting to its top, so as to being Hammer head assembly 5 to undershoot
Motion savings kinetic energy is hit, after rotating body component 6 rotates 30 ° again, the spiral between rotating body component 6 and Hammer head assembly 5 takes off suddenly
Open, now the highly pressurised liquid energy above Hammer head assembly 5 starts release, drive Hammer head assembly 5 to produce high speed impact, direct effect
On fairlead 4, fairlead 4 is delivered to impulsive force on 1 on striker, and thus the drill bit to be connected on striker 1 is carried
For moment impact, bit operation efficiency is lifted so as to produce rock breaking efficiency.
The outer surface of Hammer head assembly 5 has staggeredly been positioned apart from rotary blade b, is provided with and rotary blade b pair on rotating body component 6
The rotor groove d that should be matched.As the direction of rotary blade b is in contrary distribution with the rotor groove d direction of rotation of rotary body, therefore rotation
The motion upwards of Hammer head assembly 5 will be driven when body component 6 rotates, move to Automatic-falling tup group between a setting height rear screw
Part 5 is adjacent to striker end face in pressure and 6 bottom of action of gravity lower ram component, so as to complete once complete percussion action.
As preferred technical scheme：Rotary blade b has two row, and the outer surface along Hammer head assembly 5 is uniformly distributed, the rotary blade b of same column
It is spaced apart, is interspersed between two row rotary blade b, the quantity of the rotary blade b is 2～30, the lifting of each rotary blade b
Highly it is 2～50mm, the spiral angle of each rotary blade b is 30 °～330 °, the coil width of each rotary blade b is 10～
40mm。
Certainly, the present invention can also have other various embodiments, in the case of without departing substantially from spirit of the invention and its essence,
Those of ordinary skill in the art can make various corresponding changes and deformation according to the present invention, but these it is corresponding change and
Deformation should all belong to the protection domain of appended claims of the invention.
