The drill rod fixing device is provided with the clamping surface with the radian consistent with the outer wall of the drill rod, and the clamping surface is set as the checked surface, so that friction during contact of the fixing device and the drill rod is effectively improved, and thus the problem that the drill rod fixing device cannot firmly fix the drill rod is overcome.
Description
Technical field
The present invention relates to mechanical fastening system field, particularly, relate to a kind of device of fixing drilling rod.
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 application 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 application 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 fastening devices to fix when clean drilling rod, be convenient to clean its outer wall.Existing fastening devices is all generally that employing two or three cylinders are fixed, and such fixed form makes the fixing of drilling rod not be very firm, makes drilling rod in the phenomenon of carrying out easily skidding in the process cleaned.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of device of fixing drilling rod, fixes drilling rod fix unstable problem to overcome existing fastening devices.
The present invention's adopted technical scheme that solves the problem is: the device of fixing drilling rod, comprise fixed axis, fixed axis one end is arranged on holder, the other end is provided with fixed disk, fixed disk at least offers 2 grooves, fixed disk is provided with fixed block with groove fit place, hydraulic jack is provided with in fixed block, clamp structure is provided with in groove, clamp structure is connected on hydraulic jack, clamp structure comprises contiguous block, grip block, contiguous block is provided with projection, recess sidewall is provided with the groove I coordinated with projection, grip block is provided with the clamping face that radian coordinates with drilling-rod external wall, clamping face is set to flank.Bearing is provided with the controller controlling fixed axis and rotate, fixed axis can along the central axis rotation of self on bearing, fixed disk is fixed on fixed axis, relative to fixed axis ground still, therefore fixed axis is when rotating, fixed disk rotates around its central axis with identical rotating speed, the clamp structure controlled by hydraulic jack is provided with in fixed disk, fastening devices in use, oil drill rocker is placed between two clamp structures, primer fluid compressing cylinder, clamp structure is inwardly shunk in fixed disk radial direction makes clamp structure be stuck on drilling-rod external wall, thus by drill-rod clamping, when needs rotation only has drilling rod, start the controller on bearing, fixed axis is rotated, fixed axis drives fixed disk to rotate, thus drive the rotation of drilling rod, projection and groove I with the use of, be convenient to the slip of clamp structure in groove, and can guarantee that clamp structure is well fixed in groove, make it the skew that position can not occur in sliding process, and then improve the clamping effect of clamp structure, clamping face has the radian consistent with drilling-rod external wall, have radian clamping face can well and drilling-rod external wall well fit, improve the clamping effect of clamp structure, and clamping face is set to check face, check face is that crisscross microgroove is formed, compare general flank, check mask has and larger frictional force, further increase the clamping effect of clamping face moon drilling-rod external wall, avoid the phenomenon that drilling rod skids in fastening devices, the present invention is by arranging the consistent clamping face of radian and drilling-rod external wall by fastening devices, and clamping face is set to check face, effectively raise frictional force when fastening devices contacts with drilling rod, thus overcome existing fastening devices and fix drilling rod and fix unstable problem.
Further, the width of contiguous block is consistent with the width of groove, the width 20mm larger than the width of contiguous block of grip block.The width of contiguous block is consistent with the width of groove is convenient to the movement of clamp structure in groove, and grip block has the contact area that wider width improves grip block and drilling rod, and then improves the clamping effect of clamp structure.
Further, fixed axis protrudes from fixed disk on clamping direction.Outstanding fixed axis can insert drilling rod inwall, is convenient to the fixing of when holding drill pipe drilling rod, makes the fixing operation of drilling rod more convenient.
To sum up, the invention has the beneficial effects as follows:
1, the present invention is by arranging the consistent clamping face of radian and drilling-rod external wall by fastening devices, and clamping face is set to check face, effectively raise frictional force when fastening devices contacts with drilling rod, thus overcome existing fastening devices and fix drilling rod and fix unstable problem.
2, the present invention by being provided with projection on contiguous block, recess sidewall is provided with the groove I coordinated with projection; Grip block is provided with the clamping face that radian coordinates with drilling-rod external wall; The width 20mm larger than the width of contiguous block of grip block; Improve the clamping effect of clamp structure.
3, the present invention by protruding from fixed disk by fixed axis on clamping direction, makes the fixing operation of drilling rod more convenient.
