Consequence.Riser pipe screw thread is repeatedly subjected to the impact of Pile Hammer Impact power, easily causes the risk of screw thread stress fatigue destruction,
The Acceptable life of riser pipe is reduced, scene is accessed, the time-consuming longer of lifting short circuit is dismantled, when affecting piling work
Effect.
The content of the invention
For the deficiencies in the prior art, the technical problem to be solved in the present invention is to provide one kind prevents riser pipe from hammering
In journey rotation for short-circuit device is beaten, the device can protect riser pipe box screw thread, it is to avoid the direct damage of screw thread and tired
Labor is destroyed.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is：A kind of replacing beats short-circuit device, for beating
Between pile monkey reinforcing the heart and riser pipe, the pile hammer reinforcing the heart is provided with, described to replace
Beating short-circuit device includes pipe body, is symmetrically set in the pipe body both sides and the hanging for snapping shackle more than center of gravity
Ear, at the top of the pipe body and the antirotation keys of adaptation corresponding with the guide slot, positioned at the round bottom of the pipe can be with
Two grades of stairstepping pins that the inside retainer ring end face of the riser pipe coordinates.
Improve for a kind of of the technical scheme of short-circuit device is beaten as the present invention, being provided with the outside of the hanger to prevent shackle
It is inverted to prevent dumping.
Improve for a kind of of the technical scheme of short-circuit device is beaten as the present invention, the pin bottom is provided with removal local end
The inclined plane in face.
Improve for a kind of of the technical scheme of short-circuit device is beaten as the present invention, the inclined plane removes semicircle end face.
Improve for a kind of of the technical scheme of short-circuit device is beaten as the present invention, the inclination angle of the inclined plane is 45 °.
The beneficial effects of the present invention is：Coordinated by guide slot and antirotation keys, when pile hammer is hammered downwards, pile hammer is only
It is axially-movable, no rotary motion, guide slot limit the position of antirotation keys and prevent its circumferential activity, so as under riser pipe
Riser pipe rotation hammer during is prevented during entering effectively.Pipe body sets two grades of stairstepping pin insertion riser pipes
In, downside ladder end face is connected to inside riser pipe the retainer ring on the downside of screw thread, and the side of upper side steps is located on the inside of screw thread
And the end face of ladder is located at the top end face of riser pipe so as to protect to screw thread, Pile Hammer Impact power beats short circuit ladder by replacing
Step surface directly acts on the retainer ring inside riser pipe, protects riser pipe screw thread.
Description of the drawings
Fig. 1 is that the present invention is a kind of for beating short-circuit device and being applied in combination the structural representation of embodiment.
Fig. 2 is that the present invention is a kind of for the dimensional structure diagram of short-circuit device is beaten.
Specific embodiment
Below in conjunction with the accompanying drawings come further illustrate the present invention specific embodiment.
As shown in Figure 1 and Figure 2, the present invention is a kind of for beating short-circuit device, between pile hammer reinforcing the heart and riser pipe, institute
State pile hammer reinforcing the heart and be provided with and vertically extend and in the guide slot of lower ending opening, it is described to include pipe body 10, right for beating short-circuit device
Claim located at 10 both sides of pipe body and the hanger 12 for snapping shackle more than the center of gravity, push up located at the pipe body 10
The antirotation keys 11 of portion adaptation corresponding with the guide slot, positioned at 10 lower end of pipe body can be with the riser pipe 20
Two grades of stairstepping pins 18 that 25 end face of internal retainer ring coordinates.Coordinated by guide slot and antirotation keys 11, pile hammer is hammered into shape downwards
When hitting, pile hammer is axially-movable, no rotary motion, and guide slot limits the position of antirotation keys 11 and prevents its circumferential activity,
So as to effectively prevent rotation of the riser pipe 20 during hammering during entering under riser pipe 20, make riser pipe post with
More stable state is hammered, and reduces angle of inclination of the riser pipe post during hammering.Pipe body 10 sets two grades of stairstepping pipes
In the insertion riser pipe 20 of foot 18, lower 16 end face of side steps is connected to the retainer ring 25 on the downside of 20 inside screw thread of riser pipe, because
And second stairstepping pipe body end face of pipe body hypomere and pin 18 is interacted with 20 inside support end face of riser pipe,
Hammer force is delivered to into riser pipe 20 and the directly top of vertical riser pipe 20 and screw thread 22 is avoided, effective protection water proof is led
20 box screw thread of pipe, it is to avoid screw thread is directly damaged and fatigue rupture.The side of upper side steps 15 is located on the inside of screw thread 22 and ladder
End face be located at the top end face of riser pipe 20 so as to protect to screw thread 22, Pile Hammer Impact power is by for beating short circuit ladder platform
Terrace directly acts on the retainer ring 25 inside riser pipe, protects the end screw thread 22 of riser pipe 20.
More preferably, be provided with the outside of hanger 12 can prevent shackle it is inverted it is anti-dump 13, during hammering, steel wire rope in from
By state, prevent that dumping 13 prevention shackles comes off downwards, efficiently solve shackle and be stuck in pile hammer reinforcing the heart and for short circuit pipe body is beaten
Annular space risk.
More preferably, 18 bottom of pin is provided with the inclined plane 19 for removing partial end-face, and any semicircle body of circle bottom of the pipe goes
Except portion of material is in certain inclination angle, it is easy in operating at the scene for beating in short circuit pipe body insertion 20 box of riser pipe, it is to avoid
Damage the box screw thread of riser pipe 20.
More preferably, the inclined plane 19 removes semicircle end face, easily facilitates and maintains which for beating while short-circuit device is inserted
The intensity at 18 position of pin, can be supported for short-circuit device is beaten with a basic balance when erecting so that the device can be established and be put
Put.
More preferably, the inclination angle of the inclined plane 19 is 45 °, makes to be easily inserted riser pipe 20 and not for beating short-circuit device
Too many material need to be removed.
Ocean riser pipe use during hammering for short-circuit device is beaten in actual use, can unload ground is anti-
Button departs from hanger 12 by lifting the connection of shackle, steel wire rope and pile hammer, and slow lift-off ground inserts stairstepping pipe body 10
To the box of riser pipe 20, ladder circle body end face is made to contact with retainer ring 25 inside riser pipe box end.
Pile hammer is slowly transferred, and antirotation keys 11 prevent 20 rotation of riser pipe by coordinating with pile hammer reinforcing the heart；Drove piles
Cheng Zhong, Pile Hammer Impact power is by being transferred to riser pipe box end retainer ring 25 for beating short circuit pipe body 10, it is to avoid box screw thread
Direct damage and fatigue rupture.Prevent that dumping 13 preventions lifting shackle comes off downwards, efficiently solves shackle and is stuck in pile hammer benefit
The heart beats short circuit pipe body annular space risk with replacing.
It is above-mentioned that there is simple structure, easy to use for beating short-circuit device, can be applied not only to various oil explorations
In development field, can also be widely used in dropping hammer, in the piling work such as steam hammer, diesel hammer, hydraulic hammer.
Above disclosed is only the preferred embodiments of the present invention, and the right of the present invention can not be limited certainly with this
Scope, therefore the equivalent variations made according to scope of the present invention patent, still belong to the scope covered by the present invention.
