Abstract
The utility model relates to a damping extension bar for down-hole operations, comprising three portions like a taper screw rod, synthetic chloroprene rubber and a taper screw external cylinder, and is characterized in that the damping extension bar adopts the design of adopting a large gap to be corresponding to a screw tapering structure and filling the fine-quality synthetic chloroprene rubber into the gap, which can form a good resilient contact face under the working conditions of metal member bars bearing heavy load, pins and seated keys are not needed under the circumstance of large torsion, which can provide the anti-hunt action. In the utility model, the moment impact can be released when measuring instruments go under wells, the damage of high-vibration measuring environment to instruments can be well released, the service life and the measuring precision are extended, the cost of exchanging is lowered, and simultaneously the data deviation brought from measuring by vibration can also be solved.
Description
Technical field
The utility model relate to a kind of in oil, colliery and geological prospecting the underground work damping extension bar in drilling engineering field.
Background technology
In current petroleum industry deviational survey instrument, all unavoidably run into the impact that the impact of going into the well in instrument moment and the high environment that shakes bring, so some various forms of machineries, dampers such as hydraulic pressure arise at the historic moment, what but they faced can only alleviate axial damping, but do not have any effect diametrically, the damping diametrically of present product is not by centralizer, be exactly that inner PROCESS FOR TREATMENT solves, trouble but also improved use cost greatly not only, and reliability is not high, aspect antitorque also is to solve by sitting key and beating pin mostly, often goes wrong when operation.This just is badly in need of wanting a kind of two parts to separate, and can play axially and radially many-sided damping, and under the situation of high pulling torque and the structure that is not easy to break away from, the big gap taper thread of damping extension bar just arises at the historic moment.
Summary of the invention
The purpose of this utility model provides a kind of damping extension bar, overcomes in the existing deviational survey instrument work, because the vibrations relative influence that transmission brings to signal.Play protection down-hole deviational survey instrument, especially wherein Min Gan electronic devices and components prolong its application life.
The technical solution adopted in the utility model is: the damping extension bar comprises cone-type spiral bar, artificial caoutchouc, cone-type spiral urceolus three parts composition, the cushioning effect of damping extension bar mainly adopts the corresponding spiral taper design in big gap, and the structure of the artificial caoutchouc of high-quality is filled in the crack betwixt.Damping extension bar structure comprises an externally threaded cone-type spiral bar, the cone-type spiral urceolus of an internal thread, and two parts of top-quality rubber material connection are filled in the crack betwixt.During complete machine work, the deviational survey instrument is when being impacted and shake, and the artificial caoutchouc of filling in this structure can have good cushioning effect, to reach the purpose of damping.This utility model is a kind of lengthening rod member that multistage connection is used that can be used for simultaneously, does the internal connection of insulating electron element, can also be used to doing damper and reduces the hidden danger that potential damaging impact brings.
The utility model has not only been gathered a plurality of advantages of former damper; also improved the elastic reactance moment of torsion greatly; functions such as insulating electron components and parts can also be measured while creeping into, and data more accurately and reliably; can increase work efficiency again; simultaneously excessive impact, vibrations can be avoided, perfect damping can be played, but so also better protection down-hole deviational survey instrument; especially wherein Min Gan electronic devices and components prolong its application life.This product has high antidetonation, high reliability, and advantages such as the low and easy process and assemble of cost may also extend into others and do shock-absorbing connection and electrical isolation body.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiments the present invention is described in further detail.
Accompanying drawing is total attachment structure figure of the utility model damping extension bar.
1. cone-type spiral bars among the figure, 2. artificial caoutchouc, 3. cone-type spiral urceolus.
The specific embodiment
In order to make those skilled in the art person understand the scheme of the embodiment of the invention better, the embodiment of the invention is described in further detail below in conjunction with drawings and embodiments.
In the accompanying drawings, cone-type spiral bar (1), cone-type spiral urceolus (3) are formed by connecting by filling artificial caoutchouc (2).During complete machine work, cone-type spiral bar (1), cone-type spiral urceolus (3) are connected with the deviational survey instrument respectively, in the time of shaking force, because the artificial caoutchouc (2) that fill the metal covering contact position, form slider, make that the metal covering contact position is flexible, easy fracture not under bearing a heavy burden, the effect of buffering is arranged, so just produced cushioning effect preferably.Can effectively protect simultaneously electronic devices and components responsive in the deviational survey instrument, make the data that record more accurate.
More than the embodiment of the invention is described in detail, used the specific embodiment herein the present invention set forth, the explanation of above embodiment just is used for help understanding system and method for the present invention; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
Claims (3)
1. damping extension bar, it is characterized in that, described damping extension bar is made up of cone-type spiral urceolus three parts of externally threaded cone-type spiral bar, artificial caoutchouc, internal thread, described cone-type spiral bar and cone-type spiral urceolus adopt the corresponding spiral cone structure design in big gap, and the elastomeric material of high-quality is filled in the crack betwixt.
2. according to the described damping extension bar of claim 1, it is characterized in that: described damping extension bar can be used for the lengthening rod member that multistage connection is used.
