Fig. 1 is structural representation of the present invention.
Being labeled as in accompanying drawing: 1-power shaft, 2-trundle, 3-shake pin, 4-push rod, 5-swivel nut, 6-spring, 7-vibrating shaft, 8-outer tube, 9-sliding pin, 10-elongated hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail, but not as any limitation of the invention.
A kind of fisher concussion method, as shown in Figure 1, the method drives vibrations pin 3 to slide between one group of ratchet of vibrating shaft 7 end rotation by power shaft 1, promoting one group of ratchet of vibrating shaft 7 end, making vibrating shaft 7 produce axial concussion by shaking pin 3; The axis concussion of vibrating shaft 7 passes to outer tube 8 by sliding pin 9, then passes to the blanking plug of down-hole by outer tube 8; To the blanking plug shake pine of down-hole be stuck in by concussion impact force, under smooth completed well, be blocked salvaging and the input of plug device.Described concussion impact force is enhanced by spring 6; Spring 6 to be enclosed within the push rod 4 that is connected with power shaft 1 and to apply pretightning force by swivel nut 5 pairs of springs 6, and swivel nut 5 is connected with vibrating shaft 7; When shake pin 3 by ratchet root to ratchet top slide time, spring 6 is further compressed; After when vibrations, pin 3 crosses ratchet top, vibrations pin 3 under the effect of spring 6 release force rapid bullet to ratchet root, to strengthen the intensity of shaking impact force.
According to the device that preceding method is formed, comprise the outer tube 8 be connected with Underwell packet apparatus; Outer tube 8 is provided with one group of elongated hole be uniformly distributed along the circumference 10, is provided with sliding pin 9 in elongated hole 10, and sliding pin 9 is connected with the vibrating shaft 7 in outer tube 8, and vibrating shaft 7 and outer tube 8 are slidably connected; Vibrating shaft 7 top is provided with one group of ratchet be uniformly distributed along the circumference, and ratchet is connected with vibrations pin 3 rotational slide on power shaft 1.Described power shaft 1 is connected with push rod 4 with vibrations pin 3 through trundle 2, and on push rod 4, cover has spring 6, and spring 6 lower end withstands on the boss bottom push rod 4, and on the push rod 4 of spring 6 upper end, cover has swivel nut 5, and swivel nut 5 and push rod 4 are slidably connected; Described vibrating shaft 7 is provided with blind hole, and swivel nut 5 is threaded with the aperture of blind hole.
The course of work of the present invention and principle
As shown in Figure 1, when power shaft 1 drives push rod 4 to rotate, vibrations pin 3 on push rod 4 also rotates simultaneously, vibrations pin 3 two ends are stuck on the ratchet of vibrating shaft 7 end, when vibrations pin 3 rotates, if when the blanking plug of down-hole is stuck and can not rotates or rotate not smooth, the outer tube 8 be connected with blanking plug also cannot rotate or rotate not smooth, because the sliding pin 9 on vibrating shaft 7 limits by the elongated hole 10 on outer tube 8, vibrating shaft 7 also cannot rotate or rotate not smooth, therefore make the vibrations pin 3 on push rod 4 can only slide along the ratchet profile of tooth of vibrating shaft 7 end to rotate, when shaking pin 3 and rotating in the profile of tooth slip of ratchet, force vibrating shaft 7 can only slide up and down in outer tube 8, sliding pin 9 when vibrating shaft 7 slides up and down on vibrating shaft 7 up and down reciprocatingly impacts outer tube 8 at the elongated hole 10 of outer tube 8 and produces concussion impact force, concussion impact force passes to the blanking plug of down-hole again through outer tube 8, the blanking plug shake pine of down-hole will be stuck in by concussion impact force, the salvaging of jammed blanking plug and input under smooth completed well.In order to strengthen the intensity of concussion impact force, vibrating shaft 7 processes a central blind hole, process a boss in the lower end of push rod 4 simultaneously, push rod 4 above boss overlaps a spring 6, on the push rod 4 on spring 6 top, cover has a swivel nut 5, swivel nut 5 and push rod 4 are slidably connected, and swivel nut 5 is threaded with the aperture of central blind hole.Swivel nut 5 is pressed in spring 6 top and applies pretightning force to spring 6, make vibrations pin 3 on push rod 4 root being stuck in ratchet tightly in an initial condition, when shake pin 3 by ratchet root to ratchet top slide time, spring 6 is further compressed, after vibrations pin 3 crosses ratchet top, vibrations pin 3 rapid bullet under the effect of spring 6 release force, to ratchet root, enhances the intensity of concussion impact force.
