When switch 5 collides with valve body 4, the passage between central tube aperture and the cavity of hydraulic hammer 7 is closed, the cavity of valve body 4 and fork switch 6
Passage between cavity is opened, and drilling fluid is punished from top connection to flow, and is flowed into the cavity of fork switch 6, promoted by the cavity of valve body 4
The counterclockwise movement of fork switch 6；When fork switch 6 and hydraulic hammer 7 and valve body 4 collide, the cavity of valve body 4 and fork switch 6
Cavity is closed, and passage between the aperture of central tube 5 and the cavity of hydraulic hammer 7 is opened, drilling fluid from the aperture on central tube 5 flow out into
Into the cavity of hydraulic hammer 7, hydraulic hammer 7 and fork switch 6 is promoted to do clockwise movement；When hydraulic hammer 7 and fork switch 6 and valve body
4 when being collided, and the passage between the aperture of central tube 5 and the cavity of hydraulic hammer 7 is closed, between the cavity of valve body 4 and the cavity of fork switch 6
Passage open, drilling fluid from top connection 1 punish flow, flowed to by the cavity of valve body 4 in the cavity of fork switch 6, promote shift fork open 6
Clockwise movement is closed, completes an action cycle.
Using the technical solution of the utility model, the beneficial effect that can reach is：Its own structure of the equipment utilization, by liquid
Pressure energy is converted to mechanical energy, produces axial twisting vibration, reaches and overcomes drill string stick-slip, the purpose of bit freezing, overcomes spring reality
The drawbacks of now vibrating, it is simple in construction, the cost of manufacture is reduced, improves the reliability of equipment.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the utility model embodiment.
Mark in accompanying drawing for：1- shells, 2- lower contacts, 3- top connections, 4- valve bodies, 5- central tubes, 6- fork switch, 7-
Hydraulic hammer.
Embodiment
The preferable technical scheme of the utility model is described further with reference to the accompanying drawings and examples.
As shown in figure 1, the utility model provides a kind of torsion impact device, it include shell 1, lower contact 2, top connection 3,
Valve body 4, central tube 5, fork switch 6 and hydraulic hammer 7, the shell 1 is connected with lower contact 2, and is determined by back-up ring
Position forms inner chamber, and the top connection is placed in inner chamber, and the top connection 3 is connected with valve body 4, the valve body 4 it is interior from it is interior outward successively
Provided with central tube 5, fork switch 6 and hydraulic hammer 7, the central tube 5 connects with top connection 3, and the central tube 5 connects with valve body 4
Logical, the central tube 5 is connected and can relatively rotated with fork switch 6, and the fork switch 6 is connected with hydraulic hammer 7
And it can relatively rotate.
Preferably, described top connection 3 is provided with through hole.
