Background technology
In oil drilling field, need during well completion operations to transfer sleeve pipe.Need with transferring sleeve pipe special tool when transferring sleeve pipe.And existing sleeve pipe special tool of transferring is large because reasons in structure exists equipment volume and weight, take up room large problem, is unfavorable for applying.
Summary of the invention
In order to solve, existing to transfer sleeve pipe special tool equipment volume and weight large, and take up room large problem, and the utility model provides a kind of oil field welldrilling casing pipe running device.This oil field welldrilling casing pipe running device has equipment volume and weight is little, and take up room little feature.
The technical solution of the utility model is: this oil field welldrilling casing pipe running device comprises that transit joint, top are locking, load-bearing axle, hydraulic cylinder, load-bearing plate, leather cup, pliers tooth base and grasping tongs.Under load-bearing axle is connected to transit joint, top is locking to be connected on transit joint, under load-bearing plate is connected to load-bearing axle, under main shaft is connected to load-bearing plate, leather cup and spring are installed outside main shaft, hydraulic cylinder is connected with under load-bearing plate, hydraulic cylinder lower end is connected with lower shaft tray, under lower shaft tray, chain connection has conical pliers tooth base, is equipped with pincers tooth post, has shell outside pliers tooth base in pliers tooth base, under transit joint, chain connection has support arm, be connected with suspension ring under support arm, under suspension ring, be connected with grasping tongs, between support arm and transit joint, be connected with suspension ring hydraulic cylinder.
The utility model has following beneficial effect: this oil field welldrilling casing pipe running device is due under adopting load-bearing axle to be connected to transit joint, top is locking to be connected on transit joint, under load-bearing plate is connected to load-bearing axle, under main shaft is connected to load-bearing plate, leather cup and spring are installed outside main shaft, hydraulic cylinder is connected with under load-bearing plate, hydraulic cylinder lower end is connected with lower shaft tray, under lower shaft tray, chain connection has conical pliers tooth base, pincers tooth post is equipped with in pliers tooth base, shell is had outside pliers tooth base, under transit joint, chain connection has support arm, suspension ring are connected with under support arm, grasping tongs is connected with under suspension ring, the structure of suspension ring hydraulic cylinder is connected with between support arm and transit joint, thus equipment volume and weight is reduced, reduce and take up room, and structure is simple.This oil field welldrilling casing pipe running device has equipment volume and weight is little thus, and take up room little feature.
accompanying drawing illustrates:
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is Fig. 1 left views.
1-transit joint in figure, 2-top is locking, 3-load-bearing axle, 4-hydraulic cylinder, 5-load-bearing plate, 6-leather cup, 7-pliers tooth base, 8-grasping tongs, 9-main shaft, 10-lower shaft tray, and 11-clamps tooth post, 12-support arm, 13-suspension ring hydraulic cylinder.
detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in drawings, this oil field welldrilling casing pipe running device oil field welldrilling casing pipe running device comprises that transit joint 1, top are locking 2, load-bearing axle 3, hydraulic cylinder 4, load-bearing plate 5, leather cup 6, pliers tooth base 7 and grasping tongs 8.The preventer joint that transit joint 1 drives with top connects together, load-bearing axle 3 is connected to transit joint 1 time, top locking 2 is connected on transit joint 1, load-bearing plate 5 is connected to load-bearing axle 3 times, main shaft 9 is connected to load-bearing plate 5 times, leather cup 6 and spring are installed outside main shaft 9, load-bearing plate is connected with hydraulic cylinder 45 times, hydraulic cylinder 4 lower end is connected with lower shaft tray 10, lower shaft tray 10 times chain connections have conical pliers tooth base 7, pincers tooth post 11 is equipped with in pliers tooth base 7, shell is had outside pliers tooth base 7, transit joint 1 time chain connection has support arm 12, support arm is connected with suspension ring 12 times, grasping tongs 8 is connected with under suspension ring, suspension ring hydraulic cylinder 13 is connected with between support arm 12 and transit joint 1.
During actual use, the preventer joint that the transit joint 1 of this oil field welldrilling casing pipe running device and top drive is connected together.During setting of casing: suspension ring hydraulic cylinder 13 lifts suspension ring by the effect of stretching out, grasping tongs 8 leans forward thereupon, captures the sleeve pipe serving rig floor from dynamic catwalk, capture complete after, suspension ring hydraulic cylinder 13 is retracted, grasping tongs 8 is freely vertical, and the sleeve pipe of crawl is thereupon vertical, and now sleeve pipe is at pithead position, casing pipe running device declines, casing coupling enters overcoat by the guide effect of leather cup 6, and meanwhile, leather cup 6 has sealing function.Hydraulic cylinder 4 stretching out by cylinder bar afterwards, lower shaft tray 10 is pressed down, during lower shaft tray 10 presses down, pliers tooth base 7 and pincers tooth post 11 are pressed down simultaneously, pliers tooth base 7 declines with the inclined-plane of pincers tooth post 11 along overcoat, simultaneously towards central reduction, carry out the clamping to sleeve pipe, stop after certain position clamping, now push up the preventer joint driven to rotate, load-bearing axle 3 and load-bearing plate 5 is driven to rotate by top locking 2, now by the torsion of load-bearing plate 5 pairs of studs, stud rotates, now, overcoat rotates and drives pliers tooth base 7 and pincers tooth post 11 to rotate simultaneously, pincers tooth post 11 drives rotation of sleeve to carry out upper shackle operation.Upper button operated can unclamp pincers tooth circulate next time.This oil field welldrilling casing pipe running device adopts unique inclined-plane to compress locking sleeve, and realizes volume-diminished on this basis, saves the device space, lightweight.
