Abstract
The utility model discloses a kind of high pressure high energy jet hammer back stroke impact power unofficial biography mechanism, include piston rod, center tap inwall boss, center tap, block stamp and outer tube, the upper end of outer tube and the lower end of center tap link together, block stamp is located in the bottom and outer tube in center tap, block stamp top is stage casing, block stamp bottom is hypomere, there is block stamp foreground terrace between block stamp and hypomere, there is step surface in block stamp between stage casing and block stamp end face, stage casing top is piston rod, there is block stamp backstage terrace between piston rod and the end face in stage casing, center tap inwall, which extends internally, at least three center tap inwall boss, center tap inwall boss is located at the middle section of block stamp.Center tap lower surface 7 is located on block stamp foreground terrace 8.A large amount of losses can be produced by being propagated due to impulsive force by multistage, and now traveling to the impact energy of fluidic will decline to a great extent, so as to reach the purpose of protection fluidic.
Description
Technical field
The utility model is related to a kind of high pressure high energy jet hammer back stroke impact power unofficial biography mechanism.
Background technology
Jet hammer is typically made up of fluidic, cylinder body, piston, piston rod and block stamp etc., simple in construction, former
Reason is unique, has obtained the great attention of drilling field.Conventional low voltage jet hammer, ballistic work is small, adapted button bit, bores
Enter speed much smaller than same specification pneumatic down hole hammer, so popularization can not be obtained with promoting.High pressure high energy jetting type surges jump bit,
The rate of penetration suitable with same specification pneumatic down hole hammer can then be reached.But in complicated drilling environment, high pressure High energy water
Flow through and be often mingled with the solid particles such as rock dust landwaste, these fluidics to common material have serious erosion effect.In order to
Cemented carbide components should be used by improving its service life, but because hard alloy is fragile material, impact resistance is poor.Hydro-efflux Hammer is lived
The opening speed for filling in block stamp is very high, in the case of no buffer protection, and being ended in backward stroke of the piston, it is strong that cylinder body upper end is produced
Strong impact, collision and vibration, and the hard alloy fluidic on top is passed to, cause fluidic damage inactivation.In order to
Cemented carbide components are prevented by impact failure, should try to reduce its impulsive force being subject to.
The content of the invention
The purpose of this utility model is that the backhaul for solving existing high pressure high energy jet hammer passes to fluidic
Impact energy problems of too, and a kind of high pressure high energy jet hammer back stroke impact power unofficial biography mechanism is provided.
The utility model include step surface in piston rod, block stamp backstage terrace, center tap inwall boss, block stamp, in connect
Head, block stamp, center tap lower surface, block stamp foreground terrace and outer tube, the upper end of outer tube and the lower end of center tap link together, punching
Hammer is located in the bottom and outer tube in center tap, and block stamp top is stage casing, and block stamp bottom is hypomere, is had between block stamp and hypomere
Block stamp foreground terrace, has step surface in block stamp between stage casing and block stamp end face, stage casing top is piston rod, piston rod and stage casing
End face between have block stamp backstage terrace, center tap inwall, which extends internally, at least three center tap inwall boss, center tap
Inwall boss is located at the middle section of block stamp, and center tap lower surface is located on the terrace of block stamp foreground.
Working process and principle and beneficial effect of the present utility model：
The backhaul collision of jet hammer is changed into step surface in block stamp from the collision between piston rod and cylinder body before
With the collision between center tap inwall boss.When step surface backhaul moves upward to center tap inwall boss lower surface in block stamp
When, piston rod is with there is certain distance at the top of cylinder body, now by the impulsive force of step surface in hammer and center tap inwall boss in
Joint propagates up outer tube and cylinder body, then is transmitted to fluidic by cylinder body, because impulsive force can be produced greatly by multistage propagation
Amount loss, now traveling to the impact energy of fluidic will decline to a great extent, so as to reach the purpose of protection fluidic.
Brief description of the drawings
Fig. 1 is sectional view of the present utility model.
Fig. 2 is A-A sectional views in Fig. 1.
Wherein：Connect in step surface in 1- piston rods, 2- block stamps backstage terrace, 3- center tap inwall boss, 4- block stamps, 5-
Head, 6- block stamps, 7- center taps lower surface, 8- block stamps foreground terrace, 9- outer tubes.
Embodiment
As depicted in figs. 1 and 2, the present embodiment includes piston rod 1, block stamp backstage terrace 2, center tap inwall boss 3, punching
Step surface 4, center tap 5, block stamp 6, center tap lower surface 7, block stamp foreground terrace 8 and outer tube 9 in hammer, the upper end of outer tube 9 is with
The lower end of joint 5 links together, and block stamp 6 is located in the bottom and outer tube 9 in center tap 5, and the top of block stamp 6 is stage casing 61, punching
6 bottoms are hammered into shape for hypomere 62, there is block stamp foreground terrace 8 between block stamp 6 and hypomere 62, have between stage casing 61 and the end face of block stamp 6
Step surface 4 in block stamp, the top of stage casing 61 is piston rod 1, has block stamp backstage terrace 2 between piston rod 1 and the end face in stage casing 61,
The inwall of center tap 5, which extends internally, at least three center tap inwall boss 3, and center tap inwall boss 3 is located at the stage casing 61 of block stamp 6
Place；Center tap lower surface 7 is located on block stamp foreground terrace 8.
The working process and principle of the present embodiment：
The backhaul collision of jet hammer is changed into step surface 4 in block stamp from the collision between piston rod and cylinder body before
With the collision between center tap inwall boss 3.When the backhaul of step surface 4 moves upward to the lower end of center tap inwall boss 3 in block stamp
During face, also have certain distance at the top of piston rod 1 and cylinder body, now in hammer step surface 4 and center tap inwall boss 3 impulsive force
Outer tube 9 and cylinder body are propagated up along center tap 5, then fluidic is transmitted to by cylinder body, because impulsive force is by multistage propagation meeting
A large amount of losses are produced, now traveling to the impact energy of fluidic will decline to a great extent, so as to reach protection fluidic
