Abstract
The utility model provides a prevent torsional bumper shock absorber, including stiff end, spire and link, stiff end and link are fixed in respectively the both ends of spire, the spire includes the helical shape reed, the cross -section of reed is the quadrangle, the adoption cross -section is tetragonal reed, compares to be circular shape spring damper in traditional reed cross -section, and the twisting resistance is stronger, can guarantee consequently that instrument face very aligns with the brill in the pit.
Description
Technical field
The utility model relates to cushion technique field, particularly relates to a kind of vibration damper of anti-torsion.
Background technique
Oil instrument needs to use vibration damper in underground work, the spring damper of current use and rubber absorbers, although the axial rigidity of reducing, torsional stiffness also reduces simultaneously, be difficult to ensure very to align with brill in downhole petroleum instrument tool face, the measurement error of tool-face is increased.
Model utility content
Provide hereinafter about brief overview of the present utility model, to provide about the basic comprehension in some of the present utility model.Should be appreciated that this general introduction is not summarize about exhaustive of the present utility model.It is not that intention determines key of the present utility model or pith, neither intended limitation scope of the present utility model.Its object is only provide some concept in simplified form, in this, as the preorder in greater detail discussed after a while.
For solving the problem, the utility model proposes the vibration damper of anti-torsion, can ensure that downhole instrument tool-face is very alignd with brill, reducing the measurement error of tool-face.
A vibration damper for anti-torsion, comprises fixed end, spire and connecting end, and described fixed end and connecting end are individually fixed in the two ends of described spire, it is characterized in that, described spire comprises spiral reed, and the cross section of described reed is quadrilateral.
The vibration damper of the anti-torsion that the utility model provides, adopts cross section to be the reed of quadrilateral, is circular spring damper compared to traditional reed cross section, and twisting resistance is stronger, therefore, it is possible to ensure that downhole instrument tool-face is very alignd with brill.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the sectional view of a kind of embodiment of vibration damper of anti-torsion provided by the invention.
Embodiment
With reference to the accompanying drawings embodiment of the present utility model is described.The element described in an accompanying drawing of the present utility model or a kind of mode of execution and feature can combine with the element shown in one or more other accompanying drawings or mode of execution and feature.It should be noted that to know object, accompanying drawing and eliminate expression and the description of parts that have nothing to do with the utility model, known to persons of ordinary skill in the art and process in illustrating.
With reference to figure 1, the present embodiment provides a kind of vibration damper of anti-torsion, comprises fixed end 101, spire 102 and connecting end 103, and fixed end 101 and connecting end 103 are individually fixed in the two ends of spire 102, spire 102 comprises spiral reed 104, and the cross section of reed 104 is quadrilateral.
The vibration damper of the anti-torsion that the present embodiment provides, adopts cross section to be the reed of quadrilateral, is circular spring damper compared to traditional reed cross section, and twisting resistance is stronger, therefore, it is possible to ensure that downhole instrument tool-face is very alignd with brill, namely reaches the effect of anti-torsion.
The cross section of the reed of traditional spring is circular, namely whole reed expands into cylindrical, according to Analysis of materials mechanics, cross section is that the parts anti-twisting property of circle is weak, namely torsional stiffness is little, therefore use common spring damper connect oil instrument and bore very, be difficult to ensure very to align with brill in downhole petroleum instrument tool face.The vibration damper of the anti-torsion that the present embodiment provides, adopt cross section to be the reed of quadrilateral, namely spire expands into cuboid, can increase torsional stiffness like this, ensures the oil instrument tool face and the brill very alignment that are connected to vibration damper two ends.
The length of spire 102, the thickness of reed can design according to the actual requirements.
As one preferred embodiment, the cross section of reed 104 is rectangle, or is similar to rectangle.
As one preferred embodiment, fixed end 101, spire 102 and connecting end 103 are integrally formed.
Fixed end 101 bores very for connecting, connecting end 103 is for connecting oil instrument, the shape size of fixed end 101 and connecting end 103 can design according to the actual requirements, as one preferred embodiment, fixed end 101 and connecting end 103 are provided with mounting hole, are convenient to bore very and the installation of oil instrument.
As one preferred embodiment, the material of fixed end 101, spire 102 and connecting end 103 can be identical.Can be steel, copper, aluminium or other alloy materials.
Although described the utility model and advantage thereof in detail, be to be understood that and can have carried out various change when not exceeding the spirit and scope of the present utility model limited by appended claim, substituting and conversion.And the scope of the application is not limited only to the specific embodiment of process, equipment, means, method and step described by specification.One of ordinary skilled in the art will readily appreciate that from disclosure of the present utility model, can use perform the function substantially identical with corresponding embodiment described herein or obtain and its substantially identical result, existing and that will be developed in the future process, equipment, means, method or step according to the utility model.Therefore, appended claim is intended to comprise such process, equipment, means, method or step in their scope.
