Abstract
The utility model discloses a well drilling high pressure manifold bumper shock absorber, the on -line screen storage device comprises a base, this bumper shock absorber still includes two locking device, two locking device pass through the pillar setting respectively on the base, two locking device set up the samely, locking device includes first fixed block and second fixed block, first fixed block and second fixed block are the same semi -circular thin wall, first fixed block and pillar fixed connection, the superpose of second fixed block is on first fixed block and pass through bolted connection, set up rather than inner chamber assorted fourth fixed block in the first fixed block, set up rather than inner chamber assorted third fixed block in the second fixed block. When the intraduct fluid produces periodic shock, because the spring distributes around the pipe, the whole absorption of the effectual shock that will produce of ability to solve the vibrations of high -pressure well drilling manifold effectively, and resulted in welding seam fracture piercement's phenomenon, improved the life of high -pressure manifold greatly.
Description
Technical field
The utility model relates to drilling well high pressure pipe joint vibration damper technical field, particularly relates to a kind of drilling well high pressure pipe joint vibration damper.
Background technique
The mud high pressure pipe joint of current drill platform is fixed by the rigid support such as angle steel and deck plane Hard link, due to pulse shock and the resonance effect of the high-pressure liquid in manifold, as easy as rolling off a logly cause manifold violent oscillatory motion, pipe works under the state of vibrations for a long time, be easy to cause high pressure pipe joint weld cracking, deck plane weld cracking, also can cause time serious involving device damage, impact is produced normally.
A kind of drilling well high pressure pipe joint vibration damper such as shown in the patent No. " CN201520347608.1 ", it is provided with cluster spring between upper support block and lower support block, when high pressure pipe joint produces cyclic fluctuation due to the impulse action of fluid, upper support block is slided up and down by the guide slide processed, the energy of fluctuation is passed to cluster spring, thus play protection manifold safety, the function of damping, but this design can only help pipeline in vertical direction damping, but then can not obtain damping in other directions of pipe, long use causes the damage of pipe equally, for this reason, we propose a kind of drilling well high pressure pipe joint vibration damper.
Model utility content
The purpose of this utility model is to solve the shortcoming existed in prior art, and a kind of drilling well high pressure pipe joint vibration damper proposed.
To achieve these goals, the utility model have employed following technological scheme:
A kind of drilling well high pressure pipe joint vibration damper, comprise base, this vibration damper also comprises two locking devices, and two locking devices are arranged on base respectively by pillar, and two locking devices arrange identical.
Locking device comprises the first fixed block and the second fixed block, and the first fixed block and the secondth fixed block are identical semicircle thin-walled, and the first fixed block is fixedly connected with pillar, and the second fixed block to be stacked on the first fixed block and to be bolted.
The 4th fixed block matched with its inner chamber is set in the first fixed block, the 3rd fixed block matched with its inner chamber is set in the second fixed block, all assemblage gap is reserved with between second fixed block and the 3rd fixed block, between the first fixed block and the 4th fixed block, in two gaps, multiple spring is all set, is all connected by spring between the second fixed block with the 3rd fixed block, between the first fixed block with the 4th fixed block.
Preferably, the first fixed block, the second fixed block inwall are equipped with multiple fixed groove corresponding with spring, and spring is all positioned at fixed groove.
Preferably, spring and fixed groove interference fit are installed.
Preferably, the inwall of the 3rd fixed block is provided with the anti-slip veins with its central axis.
A kind of drilling well high pressure pipe joint vibration damper that the utility model proposes, between the second fixed block and the 3rd fixed block, all assemblage gap is reserved with between first fixed block and the 4th fixed block, in two gaps, multiple spring is all set, between second fixed block and the 3rd fixed block, all be connected by spring between first fixed block with the 4th fixed block, when the second fixed block overlaps with the first fixed block, now pipe clamp is lived by the 3rd fixed block and the 4th fixed block, when the generation of pipe internal flow is periodically shaken, because spring is distributed in the surrounding of pipe, effectively the concussion of generation all can be absorbed, thus efficiently solve the vibrations of high pressure drilling manifold, and cause weld cracking to sting the phenomenon of leaking, substantially increase the working life of high pressure pipe joint.
Accompanying drawing explanation
