Detailed description of the invention
Main thought of the present invention installs this instrument in Bottom Hole Assembly (BHA) in drillng operation, and the reciprocating motion utilizing highly pressurised liquid to realize tup as power makes impact loading realize rotating and impacting composite breaking rock stratum in drill bit.By below to the description of embodiment; to more contribute to public understanding the present invention; but the restriction that the specific embodiment given by applicant can't be considered as technical solution of the present invention, any definition to parts or technical characteristic change and/or to overall structure do form and immaterial conversion all should be considered as the protection domain that technical scheme of the present invention limits.
Hydraulic impacter as shown in Figures 1 to 4, this hydraulic impacter comprises striker 1, drive sleeve 2, shell 3, fairlead 4, Hammer head assembly 5, rotating body component 6, turbine assembly 7, joint 8, high-pressure fluid flows in impactor from joint 8, first enter in turbine assembly 7, the kinetic transformation of high-velocity fluid is the kinetic energy in rotary motion direction by turbine, thus band is automatically connected in the rotation of the rotating body component 6 on turbine assembly 7, turbine assembly 7 inside has several thrust ball bearing string to ensure the smooth and easy of turbine assembly rotary motion.Joint 8 is connected with turbine assembly 7, turbine assembly 7 is connected with rotating body component 6 by power transmission shaft, Hammer head assembly 5 is set with in rotating body component 6, Hammer head assembly 5 can move reciprocatingly along the axis direction of hydraulic impacter under the drive of rotating body component 6, when rotating body component 6 do under the drive of turbine assembly 7 rotate from axle time, the top of Hammer head assembly 5 can form variable spaces a, high-velocity fluid enters by compression supercharging in variable spaces a, for Hammer head assembly 5 provides the savings energy impacted downwards.One end of fairlead 4 is provided with guide peg, one end of Hammer head assembly 5 correspondence is provided with the gathering sill mated with guide peg, guide peg and gathering sill cooperatively interact, and limit the motion that rotates in a circumferential direction of Hammer head assembly 5, thus Hammer head assembly 5 can only be moved reciprocatingly along axis.Four holes have been opened in the power transmission shaft turbine lower end of turbine assembly 7, and central through hole and this four holes of power transmission shaft are communicated with lower flow passage.Turbine assembly 7 is along axis distribution 1 ~ 50 grade, and every grade of turbine is all made up of stators and rotators.The upper and lower side of turbine assembly 7 is all arranged for reducing in turbine rotation the wavy spring packing ring producing impact, is also provided with wavy spring stroke limit protection ring.
When under free state, (when namely this hydraulic impacter is in bottom) Hammer head assembly 5 is near fairlead 4 side, when have in drilling rod have highly pressurised liquid to flow through turbine assembly 7 time, turbine produces High Rotation Speed, by power transmission shaft driven rotary body assembly 6 High Rotation Speed, rotating body component 6 is screw joining manner (being similar to thread connecting mode) with the connected mode of Hammer head assembly 5, because the gathering sill c of tup and fairlead lead d forms the annexation of in axial direction moving only, namely Hammer head assembly 5 can only move reciprocatingly and can not rotate, make Hammer head assembly 5 can only move back and forth along axis like this, thus drive Hammer head assembly 5 to move upward when rotating body component 6 rotates, when Hammer head assembly 5 rises to a setting height (2 ~ 50mm), Hammer head assembly 5 promote process in the fluid compression supercharging in its top and rotating body component, thus be the downward ballistic motion savings kinetic energy of Hammer head assembly 5, after rotating body component 6 rotates 30 ° again, spiral between rotating body component 6 and Hammer head assembly 5 is thrown off suddenly, highly pressurised liquid energy now above Hammer head assembly 5 starts release, Hammer head assembly 5 is driven to produce high speed impact, act directly on fairlead 4, impact force to be delivered on striker on 1 by fairlead 4, so just for the drill bit be connected on striker 1 provides moment impact, thus produce rock breaking efficiency lifting bit operation efficiency.
The external surface of Hammer head assembly 5 compartment of terrain that interlocks is provided with rotary blade b, rotating body component 6 has the rotor groove d with rotary blade b Corresponding matching.Because the direction of rotary blade b is contrary distribution with the rotor groove d direction of rotation of rotary body, therefore rotating body component 6 will drive moving upward of Hammer head assembly 5 when rotating, move to Automatic-falling Hammer head assembly 5 between a setting height rear screw and be adjacent to striker end face bottom pressure and Action of Gravity Field lower ram assembly 6, thus complete once complete percussion action.As preferred technical scheme: rotary blade b has two row, external surface along Hammer head assembly 5 is uniformly distributed, the rotary blade b of same column is spaced apart, be interspersed between two row rotary blade b, the quantity of described rotary blade b is 2 ~ 30, the hoisting depth of each rotary blade b is 2 ~ 50mm, and the spiral angle of each rotary blade b is 30 ° ~ 330 °, and the coil width of each rotary blade b is 10 ~ 40mm.
Certainly; the present invention can also have other various embodiments; when not deviating from the present invention's spirit and essence thereof; those of ordinary skill in the art can make various corresponding change and distortion according to the present invention, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the present invention.
