The present invention is further illustrated below in conjunction with the accompanying drawings：
As shown in figure 1, this hydraulic impacter includes body 1, drag device 2, every pressure cylinder 3, impact body 4, hammering block 7, body 1
For a hollow circular cylinder, drag device 2 is fixed on the top of body 1, and hammering block 7 is fixed on the bottom of body 1, and hammering block 7 extend into body 1
In, it is every pressure cylinder 3 between hammering block 7 and drag device 2, is interlocked every the lower end of pressure cylinder 3 and the upper end of hammering block 7；Fixed spray in hammering block 7
Mouth 5, impact body 4 are arranged on every in pressure cylinder 3, and the outer wall of impact body 4 is engaged with every the inwall of pressure cylinder 3, the lower surface of impact body 4 and hammering block
7 upper surfaces are engaged, and impact body 4 is done circumferential reciprocating motion according to inverted " u "-shaped path；The center of drag device 2 is convex downwards with one
, projection is cylinder and circular cone combination, and impact body 4 carries the cylindrical body of step, the projection and impact body of drag device 2 for outside
4 upper ports are corresponding, and the effect of drag device 2 is when impact body 4 is in upward motion, inserts the inner chamber of impact body 4, reduces pipes' analysis
Product, formation build the pressure.Increase the up resistance of impact body 4, make the quick deceleration of impact body 4, gone out when preventing impact body 4 from moving upwards
Body 1 and produce failure.Also increase 4 times action edges of impact body simultaneously, make 4 quick speedup of impact body, improve final impulsive force.
Refering to Fig. 6, every pressure cylinder 3 be the reducing cylinder that inwall has limited step, every the upper and lower each of the limited step of pressure cylinder 3
Rectangular upper strata hole 12 and rectangular lower floor hole 11 are provided with, upper strata hole 12 and lower floor hole 11 are circumferentially evenly arranged respectively
In every on the barrel of pressure cylinder 3, upper strata hole 12 can quick pressure releasing, reduction 4 up resistance of impact body when the stress of impact body 4 is moved upwards
Power；Corresponding with the lateral grooves 10 of impact body 4 during impact body 4 is descending, formation pressure release passage is understood every the lower floor hole 11 of pressure cylinder 3,
Reduce friction in down stroke.It is evenly distributed inside pressure cylinder 3 fluted, groove center has a rhombus projection 9, with reference to Fig. 2, Fig. 3 institute
Show, impact body 4 is overall to be made up of the hollow cylinder of upper and lower two different-diameters, and upper and lower two different-diameter cylinders are in outer wall
Upper formation step, first half cylinder diameter is smaller, and lower half cylinder radius is larger.The outer steps of impact body 4 are in every pressure
The underface of 3 limited steps of cylinder, the external wall of upper portion of impact body 4 have been evenly distributed willow lobed projection 8, willow lobed projection 8 be located at every
It is corresponding between groove and rhombus projection 9 on pressure cylinder 3, it is equal every the groove on pressure cylinder 3 and rhombus projection 9 when impact body 4 moves
It is in contact with the willow lobed projection 8 in the outside of impact body 4, and guides it to do cycle movement according to inverted " u "-shaped path and produce circumferentially
Move back and forth.Rectangular recess 10 is provided with the step of impact body 4, the rectangle in 4 circumferential reciprocatory movement of impact body
Groove 10 and the process that " closing-UNICOM-closing " is constantly repeated every the lower floor hole 11 of pressure cylinder 3：Impact body 4 during up,
The lateral grooves 10 of impact body 4 every the lower floor hole 11 of pressure cylinder 3 with staggering closing, and drilling fluid builds the pressure, and action edge constantly increases on impact body 4
Greatly；During descending the lateral grooves 10 of impact body 4 with every 3 lower floor hole of pressure cylinder, 11 relative UNICOM, drilling fluid pressure release, impact body 4
Friction in down stroke reduces, and impact body 4 increases the impulsive force of hammering block 7.
The lower surface of impact body 4 is circumferentially uniformly arranged six with bevelled trapezoid boss, with reference to shown in Fig. 4, Fig. 5, anvil
Son 7 is the outside cylindrical body with step, and the upper surface of hammering block 7 is circumferentially also uniformly arranged six with bevelled trapezoid boss,
The trapezoid boss of the upper end of hammering block 7 is in contact with the trapezoid boss of the lower end of impact body 4, and the lower end of impact body 4 has 6 with bevelled
Trapezoid boss, the boss with the upper end of hammering block 7 during impact body 4 is descending are in contact, and force impact body 4 to terminate in descending process
When produce certain rotation, prevent from when impact body 4 is up returning by downlink path even stuck, ensure the suitable of inverted " u "-shaped path
Profit is completed.There is dentalation every the lower surface of pressure cylinder 3, the upper end outer wall of hammering block 7 has step, has at the step and every the lower end of pressure cylinder 3
The dentalation that face is mutually engaged, every the lower end dentalation of pressure cylinder 3, it is set to be engaged with the phase of hammering block 7, producing makes what impact body 4 rotated
Reaction force.
Sleeve 6 is provided between body 1 and hammering block 7, the middle part outer wall of hammering block 7 is eight-sided formation, and the inwall of sleeve 6 is positive eight
Side connected in star structure, hammering block 7 are engaged with the phase of sleeve 6；The inner wall lower of body 1 sets support block 13, and the upper end outer wall of hammering block 7 has fixation
Groove 14, hammering block 7 are fixed together with body 1 by support block 13, make the intentions of hammering block 7, and body 1 is threadedly coupled with sleeve 6, can be with
Upper drilling string moment of torsion is handed on.The outer octagonal structure of hammering block 7, moment of torsion is transmitted for being connected with sleeve 6.Hammering block 7 exists
Constantly vibrated under the impact of impact body 4, and drill bit is passed to by lower end mother's spiral shell screw thread.Nozzle 5 is placed on the inner chamber top of hammering block 7,
The size of the impulsive force of impact body 4 can very easily be adjusted.
Operation principle of the present invention is described as initial state in bottom dead centre with impact body 4.Because the diameter of nozzle 5 is smaller, bore
Well liquid builds the pressure here, and impact body 4 is up under upper and lower differential pressure action.The willow lobed projection 8 of impact body 4 is every in the groove of pressure cylinder 3
In the presence of rhombus projection 9, produce clockwise（Counterclockwise）Circumferentially rotate, now the outside lower end groove 10 of impact body 4 with every pressure
3 lower floor holes 11 of cylinder stagger to form closing space, the improper increase of pressure, and impact body 4 is constantly up.With up, the increasing of impact body 4
The raised insertion impactor inner chamber of device 2 is hindered, forces the upper end drilling liquid pressure increase of impact body 4, impact body 4 is decelerated to top dead-centre.With
The continuous increase of lateral pressure, impact body 4 starts to accelerate descending.The willow lobed projection 8 of impact body 4 is every water chestnut in the groove of pressure cylinder 3
In the presence of shape projection 9, produce counterclockwise（Clockwise）Circumferentially rotate, now the outside lower end groove 10 of impact body 4 with every pressure cylinder 3
Lower floor hole 11 just constantly reduces with respect to UNICOM, the lower end drilling liquid pressure of impact body 4, and impact body 4 accelerates descending.Fast downlink is transported
Dynamic impact body 4 impacts hammering block 7, and the once vibration of drill bit is realized in the presence of the pressure of the drill.Now impact body 4 is in lower dead
Point, said process is repeated, just realize the periodic longitudinal vibration of drill bit.
