Abstract
The utility model discloses a radial shock absorber which is arranged on a sensor in a pressure-proof cylinder of a measurement while drilling instrument; and the radial shock absorber comprises a split ring and at least one shock-absorbing ring, wherein a groove is arranged on an outer ring surface of the split ring, and the at least one shock-absorbing ring is sleeved in the groove of the split ring. The split ring is provided with an opening, and the opening which is opened to clamp the split ring onto a shaft of the sensor. The radial shock absorber is applicable in the radial positioning and the shock absorption to the sensor arranged in the pressure-proof cylinder of the measurement while drilling instrument, and simultaneously does not affect the positioning of the sensor in the radial and rotation directions; and the structure is simple, the installation and use are convenient, and the cost is lower.
Description
Technical field
The utility model relates to a kind of radially vibration damper, relates in particular to a kind of being applied in the steering tool, is installed in the radially vibration damper on the sensor in the resistance to compression cylinder.
Background technique
In the process of oil drilling, often need utilize steering tool that each parameter of down-hole is measured.Described steering tool is mounted in drill collar bore, is generally stock shape.The outside of the steering tool of this stock shape is the resistance to compression cylinder, electronic units such as the various sensors of inner installation.
At some sensor, in the installation process as aspect sensor, require this sensor and outside resistance to compression cylinder, and do not influence the installation and the location of all the other directions only in radial location.Particularly in some undersized aspect sensor, for fixing accelerometer, mill off the most materials on some cross section, make sensor torsional strength variation, and when installing and locating, require the elasticity positioning ring very tight, therefore cause wherein producing stress, easily cause error or sensor to damage when mounted.
Therefore, the utility model provides a kind of radially vibration damper, and it can realize sensor is carried out radially location and damping, and do not influence sensor axially and the location of sense of rotation.
The model utility content
The purpose of this utility model provides a kind of radially vibration damper, and it can realize the sensor in the resistance to compression cylinder of steering tool is carried out radially location and damping, and do not influence sensor axially and the location of sense of rotation.
For achieving the above object, the technical solution of the utility model provides a kind of radially vibration damper, and it is installed on the sensor in the resistance to compression cylinder of steering tool, comprises trip ring and at least one shock ring.Wherein, the outer ring surface of described trip ring is provided with groove, and described at least one shock ring is sheathed in the groove of this trip ring.
Further, described trip ring ringwise, it has an opening.Described opening expansible is set to the trip ring card on the axle of sensor.
The internal diameter of described trip ring is consistent with the external diameter of the axle of described sensor.
Described trip ring is to be made by the material with low coefficient of friction, for example is nylon, or poly-tetrafluoro.
Described shock ring is closed annular, and the internal diameter of this shock ring is consistent with the external diameter of the groove of described trip ring.
Described shock ring is to be made by soft and resilient material, for example is rubber, or expandable plastic.
Radially vibration damper described in the utility model is applicable to the sensor in the resistance to compression cylinder that is installed in steering tool is carried out radially location and damping, can not influence simultaneously yet sensor axially and the location of sense of rotation.
Radially vibration damper described in the utility model, simple in structure, easy to install, cost is lower.

Described trip ring 1 is to be made by the material with low coefficient of friction, for example is nylon, or poly-tetrafluoro.
Described shock ring 2 is to be made by soft and resilient material, for example is rubber, or expandable plastic.
Radially vibration damper described in the utility model is applicable to the sensor in the resistance to compression cylinder that is installed in steering tool is carried out radially location and damping, can not influence simultaneously yet sensor axially and the location of sense of rotation.
Radially vibration damper described in the utility model, simple in structure, easy to install, cost is lower.
Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple modification of the present utility model with to substitute all will be conspicuous.Therefore, protection domain of the present utility model should be limited to the appended claims.
