Abstract
A deoscillator of wireless declinator while drilling comprises a deoscillator shell, a hollow screwed pipe, an upper gasket, a rubber sleeve (made from cyaniding butyronitrile), a lower gasket, an anti-rotating pin, a spacing nut, a guide tube and a damping rubber ring which are all made from non-magnetic copper materials. The deoscillator shell is arranged on the outermost, the anti-rotating pin is installed in a hole of the guide tube, the spacing nut, the lower gasket, the rubber sleeve and the upper gasket are installed on the outer portion of the guide tube in turn, the lower end of the hollow screwed pipe and the upper end of the guide tube are tightened through screw threads to form a damping assembly, the damping assembly is installed in a cylinder of the deoscillator shell, the spacing nut is fixed on the inner wall of the deoscillator shell, and the damping rubber ring is located in a groove on the outer diameter of the deoscillator shell. As the deoscillator adopts a hollow design, wires can penetrate through the center of the deoscillator, as adopting the deign of the bidirectional compression rubber sleeve, the deoscillator does not have the problem of damage because of pulling force, and as adopting the anti-rotating pin, the deoscillator can not rotate in work.
Description
Technical field
The utility model relates to a kind of wireless drilling inclinometers damper, and it is mainly used in the damping of (in the oil drilling process) instrument electronic unit under the high temperature big bang operating mode.
Background technology
The damper of present domestic wireless drilling inclinometers mainly contains spring, rubber suspension type, fluid pressure type several types.Wherein spring in use is easy to fatigue damage, and two ends twist easily.The rubber suspension damper does not add spacing, ruptures easily when being subjected to big impact, and two ends also twist easily, and this will have influence on the certainty of measurement of instrument, and the certainty of measurement problem has become the problem that the oil field user comparatively is concerned about.Though hydra-shock absorber does not have torsion problem, the easy leakage of oil of its oil-filled sealing was lost efficacy.They also have a common problem: the lead that is exactly instrument all needs in the metallic channel of damper outside.In abominable environment for use, be easy to cause the lead breakage, directly influence work.
The utility model content
The purpose of this utility model provides a kind of advantages of simple, reliable operation, cabling convenience, does not have the wireless drilling damper that reverses, do not have magnetic.
For achieving the above object, the utility model has adopted following technical proposals: its overall plan is made up of damper shell, hollow screwed pipe, upper gasket, rubber sleeve (material is the cyaniding butyronitrile), lower gasket, stop pin, stop nut, guide pipe, yielding rubber circle.Above-mentioned various material is all selected no magnetic copper product for use.The damper shell is cylindric, at the outermost of damper, stop pin is loaded in the hole of guide pipe, and stop nut, lower gasket, rubber sleeve, upper gasket are loaded on the guide pipe outside successively, the lower end of hollow screwed pipe and guide pipe upper end tighten by screw thread, constitute dampening assembly; Dampening assembly is contained in the cylinder of damper shell, and stop nut is fixed on the inwall of damper shell by external screw thread; The yielding rubber circle is arranged in the groove of damper shell external diameter.
Described damper shell is cylindric, and the one end can be connected with instrument; Stop pin can be installed in the hole of guide pipe, stop nut, lower gasket, rubber sleeve, upper gasket are installed then successively, are coated shockproof glue basedly afterwards at the screw thread place of hollow screwed pipe, the screw thread of hollow screwed pipe and guide pipe is tightened, form dampening assembly, this moment, rubber was with certain pretightning force;
The above-mentioned dampening assembly that assembles is installed in the cylinder of damper shell, at the screw thread place of stop nut gluing, and first-class screw thread, after the glue drying, the yielding rubber circle of installing on the outer diameter groove gets final product, and an end of guide pipe can connect the parts that need damping.Use the yielding rubber circle can play certain radially cushioning effect.
In the use, because vibrations, when pulling force was born at the damper two ends, guide pipe was by hollow screwed pipe pulling upper gasket, and the compressing rubber cover is stressed on stop nut, and this moment, rubber sleeve was stressed.When pressure was born at the damper two ends, guide pipe was stressed in damper shell inboard by lower gasket compressing rubber cover, and rubber sleeve still is stressed.Adopt the design of bi-directional compression rubber sleeve, therefore, damper always is stressed when work, the problem that not damaged by pulling force; Because the effect of stop pin, damper is non-rotatable when work; And hollow screwed pipe and guide pipe are hollow design, and the utility model embodiment can wear lead in the center, provides bigger convenience to use.
Compare with domestic like product, this damper has following characteristics:
1. shell body all adopts the manufacturing of copper metal, and is comparatively firm, and do not have magnetic.
2. no matter damper bears pulling force or pressure, and its rubber ring all bears pressure, and its force-bearing situation is reasonable.
3. during the stressed unbalance loading in damper two ends, can not use parts to twist.
4. line is crossed at the center comparatively easily, is difficult for causing the lead breakage.
Description of drawings
Accompanying drawing 1 is the structural representation of wireless drilling inclinometers damper
Wherein: 1, damper shell, 2, hollow screwed pipe, 3, upper gasket, 4, rubber sleeve, 5, lower gasket, 6, stop pin, 7, stop nut, 8, yielding rubber circle, 9, guide pipe.
The specific embodiment
Referring to Fig. 1 is structural representation of the present utility model, and visible damper shell 1 is cylindric, at the outermost of damper;
As seen rubber sleeve 4 is between upper gasket 3 and lower gasket 5, and in use, when the damper two ends were subjected to pulling force, guide pipe 9 drove hollow screwed pipe 2, pulling upper gasket 3, and compressing rubber cover 4, rubber sleeve 4 is stressed; When damper bore pressure, guide pipe 9 overlapped 4 stressed in damper shell 1 inboard by lower gasket 5 compressing rubbers, and rubber sleeve 4 still is stressed.As seen, damper always is stressed when work, the problem that not damaged by pulling force;
As seen damper shell 1, hollow screwed pipe 2, guide pipe 9 are hollow design, and lead can be worn in the center;
As seen stop pin 6 is between guide pipe 9 and stop nut 7, and in the damper course of work, stop pin 6 is axially movable only, but non-rotatable.
In accompanying drawing 1, damper shell 1 is installed in outermost, hollow screwed pipe 2, upper gasket 3, rubber sleeve 4, lower gasket 5, stop pin 6, guide pipe 9 are cascaded, and fixing with damper shell 1 with stop nut 7, yielding rubber circle 8 is installed in the groove of damper shell 1.
