Description
Technical field
The present invention relates to mechanical gripping means field, particularly, relate to the drilling rod fixator of clamping relatively in a kind of radial direction.
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 maintenance at every turn clean after using drilling rod to drilling rod.Drilling rod is in the process used, the scrap things such as the earth that drilling well produces, aggregate chips, oil stain can adhere to early drilling-rod external wall, the outer wall of drilling rod can be corroded, the service life of drilling rod can be had influence on, and can impact the use next time of drilling rod, the drilling rod being attached with scrap thing can have influence on quality and the operating efficiency of drilling well next time, therefore, drilling rod must clean it after a procedure, because the diameter of drilling rod used in petroleum machinery is larger, therefore need drilling rod clamping device to fix when clean drilling rod, be convenient to clean its outer wall.Existing clamping device is all generally that the outer wall of drilling rod is fixed by employing two or three cylinders, and such fixed form easily causes drilling rod to be out of shape by the place of clamping.
Summary of the invention
Technical problem to be solved by this invention to be to provide in a kind of radial direction the drilling rod fixator of clamping relatively, and to overcome existing clamping device, to fix drilling rod be the problem easily causing drilling rod to be out of shape.
The present invention's adopted technical scheme that solves the problem is: the drilling rod fixator of clamping relatively in radial direction, fixed axis, fixed axis one end is arranged on holder, the other end is provided with fixed disk II, fixed axis is provided with the fixed disk I coordinated with fixed disk II, fixed disk I is arranged between holder and fixed disk II, fixed disk I is at least evenly provided with 2 groove I, fixed disk I is provided with fixed block I with groove I cooperation place, hydraulic jack I is provided with in fixed block I, clamp structure I is provided with in groove I, clamp structure I is connected with hydraulic jack I, fixed disk II is at least evenly provided with 2 groove II, fixed disk II is provided with fixed block II with groove II cooperation place, hydraulic jack II is provided with in fixed block II, clamp structure II is provided with in groove II, clamp structure II is connected with hydraulic jack II.Existing clamping device is all generally the one-side outer wall to drilling rod or inwall clamps admittedly, the weight of oil drill rocker is general all larger, need by larger strength in order to clamp drilling rod, the inside and outside wall discontinuity of drilling rod in clamping process, and used drilling rod has certain losing in intensity, therefore the distortion that one-side clamping easily causes drilling rod is carried out to oil drill rocker inside and outside wall, fixed disk I of the present invention, fixed disk II is cylindrical structure, hydraulic jack I controls the movement of clamp structure I in groove I, hydraulic jack II controls the movement of clamp structure II in groove II, this clamping device in use, first drilling rod being inserted clamping device makes clamp structure II in drilling rod, clamp structure I is outside drilling rod, by hydraulic jack II, clamp structure II is expanded outwardly in the radial direction of fixed disk II, until clamp structure II blocks at drilling rod inwall firmly, by hydraulic jack I, clamp structure I is inwardly expanded in the radial direction of fixed disk I, until clamp structure I blocks firmly at drilling-rod external wall, the present invention clamps the outer wall of drilling rod, inwall respectively by arranging clamp structure I, clamp structure II simultaneously, avoid one-sidely from drilling-rod external wall or inwall, drilling rod to be clamped, drilling rod distortion that drilling rod inside and outside wall discontinuity causes, thus overcoming existing clamping device, to fix drilling rod be the problem easily causing drilling rod to be out of shape, and outer wall, inwall carry out pressing from both sides and improve the stability that clamping device fixes drilling rod simultaneously.
Further, the width of one end that clamp structure I is fastened in groove I is less than the one end coordinated with oil drill rocker; The width of one end that clamp structure II is fastened in groove II is less than the one end coordinated with oil drill rocker.One end that clamp structure I, clamp structure II are less is fastened in groove I, groove II respectively, be convenient to the movement of clamp structure I, clamp structure II, width clamp structure I, clamp structure II being used for the one end clamping oil drill rocker is set to be greater than the other end, improve clamp structure I, clamp structure II and the contact area of oil drill rocker, improve the clamping stability of clamp structure I, clamp structure II.
Further, groove I is symmetrically arranged with 2, and groove II is symmetrically arranged with 2, and the line of two groove I is vertical with the line of two groove II.This structure can guarantee that clamping device can by drill-rod clamping.
Further, groove I is evenly provided with 4, and groove II is symmetrically arranged with 2.This structure can guarantee that clamping device can by drill-rod clamping.
To sum up, the invention has the beneficial effects as follows:
1, the present invention clamps the outer wall of drilling rod, inwall respectively by arranging clamp structure I, clamp structure II simultaneously, avoid one-sidely from drilling-rod external wall or inwall, drilling rod to be clamped, drilling rod distortion that drilling rod inside and outside wall discontinuity causes, thus overcoming existing clamping device, to fix drilling rod be the problem easily causing drilling rod to be out of shape.
2, the present invention is less than to the width of the outer wall of drilling rod, inwall clamps, clamp structure I is fastened in groove I one end simultaneously the one end coordinated with oil drill rocker respectively by arranging clamp structure I, clamp structure II; The width of one end that clamp structure II is fastened in groove II is less than the one end coordinated with oil drill rocker, improves the stability that clamping device fixes drilling rod.
