Description
Technical field
The present invention relates to petroleum machinery processing unit (plant), be specifically related to a kind of clamping device and improve structure.
Background technology
In the recovery process of oil, drilling rod is a kind of requisite instrument, and drilling rod is reusable, in order to improve the service life of drilling rod, must carry out drilling rod safeguarding cleaning after using finishing drilling bar every time.Drilling rod is in the process used, the scrap things such as earth, aggregate chips, oil stain produced by drilling well can adhere to early drilling-rod external wall, the outer wall of drilling rod can be corroded, influence whether the service life of drilling rod, and the use next time of drilling rod can be impacted, the drilling rod being attached with scrap thing influences whether quality and the work efficiency of drilling well next time, and therefore, it must be cleaned by drilling rod after a procedure.
Owing to the length of drilling rod used in petroleum machinery is longer, reason due to gravity, the middle part of drilling rod can be recessed, whole workpiece in the state of bending, the of long duration deformation that may result in drilling rod, affect the later stage use of drilling rod, in order to avoid the problems referred to above, clamp structure is usually adopted to clamp at the middle part of drilling rod, it is to avoid being bent downwardly under gravity in the middle part of drilling rod, existing clamp structure is not easy to operation.
Summary of the invention
Present invention aim at providing a kind of clamping device to improve structure, to solve the problem that existing clamp structure is not easy to operation.
The present invention is achieved through the following technical solutions:
A kind of clamping device improves structure, including outer toroid and interior annulus, described interior annulus is positioned at outer toroid, and outer toroid and interior annulus are donut, described outer toroid is connected by connecting rod and interior annulus are fixing, described interior annulus is provided with at least one tapped through hole, the bolt coordinated with tapped through hole it is provided with in described tapped through hole, described outer toroid is provided with through hole, cover plate one end is hinged with the inwall of through hole, the other end is provided with lug, lug is provided with fixed via, outer toroid is provided with the groove with tab cooperation, the bottom of groove is provided with the screwed hole coordinated with fixed via, cover plate is fixed in outer toroid by bolt I with coordinating of screwed hole, described through hole and bolt are correspondingly arranged.
Existing clamping device is in order to improve the stability of clamping, it will usually adopt the clamping device of twin nuclei, adopts bolt to fix, but the bolt of existing dicyclo clamping device is not easy to operation.
But through hole circular hole of the present invention, it is also possible to be square opening.
The work process of the present invention: will be disposed within the middle part of drilling rod in annulus, cover plate is opened, by instrument or hands are removed rotating bolt through through hole, until fitting with drilling rod, it is rotated further by bolt, make bolt that slip is tight, then cover plate is fixed in outer toroid, several clamping device can be set according to the physical length of drilling rod more.
The present invention is by arranging through hole, enabling bolt axially carry out rotating bolt, compare the rotation carrying out bolt in other orientation, improve the convenience of operation.
The present invention is by arranging the cover plate coordinated with through hole, cover plate is fixed in outer toroid by bolt I with coordinating of screwed hole, in avoiding clamping device to have foreign body through hole again to enter into clamping device and then clash in the process of holding drill pipe, annulus is thus having influence on the serviceability of interior annulus, at the axial place of clamping device owing to being identical setting, without the concern for foreign body clash into problem, and if clamping device radially by through hole enter can directly clash in annulus.
The present invention, by arranging the interior annulus and outer toroid being mutually permanently connected, improves the stability of clamping.
Further, bolt one end inside interior annulus is provided with grip block, and the clamping face of grip block is provided with 4 hemispherical projections.
Form spill clamping face between 4 hemispherical projections, it is possible to increase grip block and the frictional force of drilling rod, improve clamping effect.
Further, 4 hemispherical projections are each provided at 4 diagonal angles place of clamping face.
Further, the diameter of hemispherical projections is less than the 1/2 of clamping face width.
Further, the screw on interior annulus has 3.
Further, connecting rod place straight line overlaps with the diameter of outer toroid.
Be conducive to improving the stability connected between interior annulus and outer toroid.
Further, connecting rod has 3, and connecting rod is equally distributed on interior annulus.
Uniform force is balanced, improves the fastness of clamping further.
The present invention compared with prior art, has such advantages as and beneficial effect:
1, the present invention is by arranging through hole, enabling bolt axially carry out rotating bolt, compare the rotation carrying out bolt in other orientation, improve the convenience of operation.
2, the present invention is by arranging the cover plate coordinated with through hole, cover plate is fixed in outer toroid by bolt I with coordinating of screwed hole, it is to avoid clamping device have in the process of holding drill pipe foreign body through hole again enter into clamping device so that clash in annulus thus having influence on the serviceability of interior annulus.
