Abstract
The utility model discloses drilling equipment, in particular to a cylinder body and a cylinder cover of a jet type hydraulic impactor used for percussion drilling in the construction of oil gas welldrilling and rock drilling. The cylinder body and the cylinder cover are formed as follows: an upper cylinder cover is welded into a side groove where the top part of the cylinder body corresponds toa lower cavity of the cylinder body, the space between the upper cylinder cover and the cylinder body is communicated with the lower cavity of the cylinder body via at least two waisted holes which are distributed in the shape of a ring and arranged on one side of the cylinder body, tie bars are arranged between the waisted holes, and the lower cylinder cover is inserted into an inner hole of thecylinder body. The utility model solves the structural design form of the liquid stream channel of the cylinder body lower cavity of the prior jet type hydraulic impactor, and solves the problem the sealing between the main components of the prior jet type impactor is easy to lose function.
Description
Technical field:
This usefulness is novel to relate to jetting type that a kind of drilling tools, especially oil/gas drilling, Rock and Soil Drilling Engineering percussion drilling use the surge cylinder body and the cylinder cap of impactor.
Background technology
The jetting type impactor that surges generally is made up of fluidic, cylinder body, the piston that is arranged at inner chamber of cylinder block, piston rod and the upper cavity that inner chamber of cylinder block is divided into by piston, lower chamber and block stamp etc.The seal form that jetting type surges between the inner critical piece of impactor has multiple.A kind of deep-well drilling jet flow type shocker that surges is disclosed in CN2385068Y, its inner critical piece adopts the rubber seal sealing, promptly between inner casing and outer shell, rubber seal is set, make between the bar shaped gap of inner casing lateral wall and the outer inside wall of cylinder and form seal channel, make the purpose that enters the cylinder body cavity of resorption from the high-pressure fluid of fluidic thereby reach.This seal form can satisfy instructions for use substantially at geological core drilling and engineering construction field.But in oil drilling and geothermal well drilling process, along with temperature in the increase hole of drilling depth constantly raises, the rubber seal that directly contacts with the outer inside wall of cylinder is aging and cause seal failure under hot conditions easily.High-pressure fluid enters the air-proof condition of cavity of resorption passage in case destroy the operate as normal will influence fluidic, and if high-pressure spray can not normally switch, also may cause fluidic to damage because of one-sided continuous erosion.Simultaneously, the hidden danger that this seal form exists rubber seal " to be cut bad " in the critical piece installation process, in use rubber seal is subject to the erosion of drilling fluid.Sealing in CN2550477Y between the critical piece of disclosed a kind of jet flow type shocker improves, the closed channel that will use the rubber seal sealing and form changes integrated passage into, promptly with a circular-arc long-bar metal sheet that matches with the cylindricality outer surface of cylinder block side chamber channel welds on the cylinder body is sealed.This sealing means in use exists the welding position cracking to cause the potential risk of seal failure.In addition, sealing between the jet flow type shocker critical piece also has other modes, but owing to be subjected to the restriction of existing jet flow type shocker cylinder body self structure form and service condition, the sealing problem between the jet flow type shocker critical piece is not solved.
The surge fluid course of impactor cylinder body cavity of resorption of present jetting type is assembled with the outer inside wall of cylinder by bar shaped gap on the outer wall of cylinder block and forms, its sealing means has multiple, but the influence of restriction of impactee cylinder body self structure form and service condition, all there is deficiency in every kind of sealing means and the jetting type sealing of surging between the impactor critical piece was lost efficacy easily, and then influences the normal work of impactor.
Summary of the invention:
The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art, and a kind of jet flow type shocker cylinder body and cylinder cap with excellent sealing is provided.
The purpose of this utility model is achieved through the following technical solutions:
Jet flow type shocker cylinder body and cylinder cap are by: upper cylinder cover 4 welding-ons or are bonded in the corresponding side groove of cylinder body 6 tops and cylinder body cavity of resorption 11, upper cylinder cover 4 is communicated with by mounting hole or circular hole 7 with cylinder body cavity of resorption 11 with the space 5 of 6 of cylinder bodies, and following cylinder cap 12 inserts cylinder body 6 endoporus.
The purpose of this utility model can also be achieved through the following technical solutions:
One side of cylinder body 6 is provided with the mounting hole or the circular hole 7 of two annular array at least, is provided with lacing wire 8 between mounting hole or the circular hole 7.
Beneficial effect: the utility model has changed the surge structure design form of impactor cylinder body cavity of resorption fluid course of existing jetting type, has solved the difficult problem that sealing was easily lost efficacy between the existing jet flow type shocker critical piece.
