The specific embodiment
Main thought of the present utility model, is in Bottom Hole Assembly (BHA), this instrument to be installed in drillng operation, and the reciprocating motion that utilizes highly pressurised liquid to realize tup as power makes impact loading realize rotation and impact composite breaking rock stratum in drill bit.By the description to embodiment below; to more contribute to public understanding the utility model; but specific embodiment given applicant can't be considered as to the restriction to technical solutions of the utility model, any definition to parts or technical characterictic change and/or to overall structure do form and immaterial conversion all should be considered as the protection domain that the technical solution of the utility model limits.
Hydraulic impacter as shown in Figures 1 to 6, 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, turbine is the kinetic energy of direction of rotatablely moving by the kinetic transformation of high-velocity fluid, thereby band is automatically connected in the rotation of the rotating body component 6 on turbine assembly 7, and it is smooth and easy that turbine assembly 7 inside have several thrust ball bearing strings to guarantee that turbine assembly rotatablely moves.Joint 8 is connected with turbine assembly 7, turbine assembly 7 is connected with rotating body component 6 by power transmission shaft, in rotating body component 6, be set with Hammer head assembly 5, 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 does in the time that axle rotates under the drive of turbine assembly 7, the top of Hammer head assembly 5 can form variable spaces a, high-velocity fluid enters compressed supercharging in variable spaces a, for Hammer head assembly 5 provides the savings energy of downward impact.One end of fairlead 4 is provided with guide peg, one end of Hammer head assembly 5 correspondences is provided with the gathering sill mating with guide peg, guide peg and gathering sill cooperatively interact, and limited the motion that rotates in a circumferential direction of Hammer head assembly 3, thereby Hammer head assembly 3 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 the central through hole of power transmission shaft and these four holes are communicated with lower flow passage.Turbine assembly 7 distributes 1～50 grade along axis, and every grade of turbine is all made up of stator and rotor.The upper and lower side of turbine assembly 7 is all provided for reducing in turbine rotation and produces the wavy spring packing ring impacting, and is also provided with wavy spring stroke limit protection ring.
When (when this hydraulic impacter is in bottom) Hammer head assembly 5 under free state is near fairlead 4 one sides, when having while having highly pressurised liquid to flow through turbine assembly 7 in drilling rod, turbine produces High Rotation Speed, by power transmission shaft driven rotary body assembly 6 High Rotation Speeds, rotating body component 6 is spiral connected mode (being similar to thread connecting mode) with the connected mode of Hammer head assembly 5, because gathering sill c and the fairlead lead d of tup form only the in axial direction annexation of motion, be that Hammer head assembly 5 can only move reciprocatingly and can not rotate, make like this Hammer head assembly 5 to move back and forth along axis, thereby in the time that rotating, rotating body component 6 drive Hammer head assembly 5 to move upward, when Hammer head assembly 5 rises to a setting height (2～50mm), Hammer head assembly 5 is the fluid compression supercharging in rotating body component to its top in the process promoting, thereby be the downward ballistic motion savings kinetic energy of Hammer head assembly 5, when rotating body component 6 rotates after 30 ° again, spiral between rotating body component 6 and Hammer head assembly 5 is thrown off suddenly, now the highly pressurised liquid energy of Hammer head assembly 5 tops starts to discharge, drive Hammer head assembly 5 to produce high speed impact, act directly on fairlead 4, fairlead 4 is delivered to impact force on striker on 1, so just for the drill bit being connected on striker 1 provides moment impact, thereby produce rock breaking efficiency and promote drill bit operating efficiency.
The staggered compartment of terrain of external surface of Hammer head assembly 5 is provided with rotary blade b, has the rotor groove d with rotary blade b Corresponding matching on rotating body component 6.Because the direction of rotary blade b and the rotor groove d direction of rotation of rotary body are contrary distribution, therefore will drive moving upward of Hammer head assembly 5 when rotating body component 6 rotates, move to Automatic-falling Hammer head assembly 5 between a setting height rear screw and be adjacent to striker end face at pressure and Action of Gravity Field lower ram assembly 6 bottoms, thereby 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, between two row rotary blade b, be interspersed, 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 utility model can also have other various embodiments; in the situation that not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
