Abstract
The utility model relates to a device for centering drill rods in oilfield drilling equipment, in particular to a drill rod centering device used for drill rod racking. The utility model adopts the technical scheme that two shaft holes are formed on the vertical plate of a right-angled support frame; a centering claw penetrates the shaft holes respectively, a vertical flexible driving mechanism is arranged on the horizontal seat of the right-angled support frame, a connecting block is fixed at the upper end part of the driving mechanism, the two ends of the connecting block are respectively connected and matched with the inner side end of the centering claw through a lock plunger and a chute, and an arc-shaped claw is arranged at the other end of the centering device. In the utility model, through controlling and operating the driving mechanism (a hydraulic cylinder, or a pneumatic cylinder and the like), the drill rod centering device achieves the involution or the expansion between the centering blocks, thereby achieving the effect of restricting the position of the drill rod; and the drill rod centering device can be used together with a hoisting mechanism in the prior art, can also be served as associated equipment for totally solving the problems in full mechanization and automation progresses of a drill rod racking system, and can also well solve the problem of rocking during drill rod racking process.
Description
Technical field
The utility model relates in a kind of oil drilling equipment and is used for the device that drilling rod is set upright, a kind of drilling rod erection device that is used for pipe racking of saying so more specifically.
Technical background
Pipe racking is in the drilling process drilling rod to be moved to well head or moves to the necessary process of discharging on the frame from well head from the discharging frame.At present in the drillng operation drilling rod work that to put be that the workman operates elevator, be connected to the box cupling place of drilling rod by elevator, sling (or transferring) drilling rod to assigned address by lifting machinery then, again by workman's release elevator of seting out, this extracting and to discharge the drilling rod operation abnormally dangerous and labour intensity is big, operating efficiency is also very low, if adopt automatic discharge device, distinct issues are that swing can appear in drilling rod drilling rod in the process that moves.
The utility model content
The purpose of this utility model is exactly at the problems referred to above, and the drilling rod erection device of swinging in a kind of effective control drilling rod moving process is provided.
Its technical scheme is: two axis holes are set on the riser of a right angle bracing frame at interval, be penetrated with respectively in the axis hole and set upright pawl, vertical telescopic drive mechanism is set on the horizontal base of right angle bracing frame, the upper end of driving mechanism is fixed with contiguous block, the two ends of contiguous block are connected cooperation with the medial extremity of setting upright pawl by locking bolt respectively with chute, at the other end of setting upright pawl the arc pawl is set.Described driving mechanism comprises a kind of of hydraulic cylinder or pneumatic linear actuator.
Drilling rod erection device of the present utility model is by operation control driving mechanism (hydraulic cylinder or pneumatic linear actuator etc.), realize involutory between the wiper block or open, reach drilling rod is discharged and grasps, both can be used with existing derricking gear, also can provide supporting, and can be good at solving the problem of rocking in the pipe racking process for Fully-mechanized, the automated process that solves pipe pick up and lay down system comprehensively.
Description of drawings
Accompanying drawing is the overall structure schematic diagram of a kind of exemplary embodiments of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description:
With reference to accompanying drawing, two axis holes are set on the riser of a right angle bracing frame 1 at interval, be penetrated with left and right pawl 2 and 3 set upright in the axis hole respectively, vertical hydraulic cylinder 6 is set on the horizontal base of right angle bracing frame 1, the upper end of hydraulic cylinder 6 is fixed with contiguous block 5, the two ends of contiguous block 5 are connected cooperation with the medial extremity of setting upright pawl by locking bolt respectively with chute, at the other end of setting upright pawl the arc pawl is set.
Hydraulic cylinder also can change pneumatic linear actuator into, can certainly take type of drive such as motor-driven helical axis or bent axle.
Its operating principle is, the reciprocating process of hydraulic cylinder drives two, and to set upright pawl involutory or open, and drilling rod is being set upright in the pawl fashionable being locked in, and reaches the purpose of restriction swing.
Claims (2)
1, a kind of drilling rod erection device, it is characterized in that: two axis holes are set on the riser of a right angle bracing frame at interval, be penetrated with respectively in the axis hole and set upright pawl, vertical telescopic drive mechanism is set on the horizontal base of right angle bracing frame, the upper end of driving mechanism is fixed with contiguous block, the two ends of contiguous block are connected cooperation with the medial extremity of setting upright pawl by locking bolt respectively with chute, at the other end of setting upright pawl the arc pawl is set.
