Technical field
The invention belongs to the petroleum machinery technical field, relate to a kind of lifting type drilling and repairing machine with power cat road.
Background technology
Basically all be to adopt cat road, ground and ramp carrying at present, mechanically lean on artificial drill string to carry on the rig floor face (ground) (on the rig floor face) on the ground with the drill string of oil drilling and repairing machine.The deficiency that this operation exists is: the one, and labor strength is big, and the 2nd, there is serious potential safety hazard, the 3rd, efficient is lower.Though the relevant higher power cat road of automatization level has appearred now, its complex structure, and manufacturing cost is higher, and influence is promoted the use of.
Summary of the invention
The purpose of this invention is to provide a kind of lifting type drilling and repairing machine with power cat road,, have complex structure, the manufacturing cost problem of higher though it is higher to have solved available dynamic cat road automatization level.
The technical scheme that the present invention adopted is, a kind of lifting type drilling and repairing machine is with power cat road, and base is provided with lift arm, and lift arm is hinged through the fixedly lug on rotating shaft termination lug and the base; Simultaneously the middle part lug of lift arm also through elevating ram and base another fixedly lug is hinged; The lift arm upper surface is provided with guide rail, and many group leading block groups are installed in the guide rail, is installed with the V-type groove on the leading block group, and the V-type groove is hinged through telescopic oil cylinder and lift arm.
The invention has the beneficial effects as follows, rise, the drill down operator manual intervention reduces, and can effectively alleviate personnel's working strength, improves the efficient that drill string is handled; Whole system adopts hydraulic control, and hydraulic jack adopts the interlocking design in the hydraulic system, and current state that can maintaining body under system's decompression state is safe and reliable.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is elaborated.
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5; Lifting type drilling and repairing machine of the present invention with power cat road structure is; Be provided with base 8 on the ground; Base 8 is provided with lift arm 2, and lift arm 2 is through the fixedly lug on rotating shaft termination lug and the base 8 hinged (with respect to the far-end of well head), and this termination lug is realized pegging graft through lifting arm axle 7 and rotated; Simultaneously the middle part lug of lift arm 2 is also through another fixing lug hinged (with respect to the near-end of well head) of elevating ram 1 and base 8; Lift arm 2 upper surfaces are provided with guide rail 9, and many group leading block groups 5 are installed in the guide rail 9, are installed with V-type groove 4 on the leading block group 5, are placed with drill string 6 in the V-type groove 4, and the soffit lug of V-type groove 4 is hinged through telescopic oil cylinder 3 and lift arm 2 rotating shaft terminations.
The two ends of elevating ram 1 all through the bearing pin mode respectively with base 8 and lift arm 2 is hinged, the two ends of telescopic oil cylinder 3 are all hinged with V-type groove 4 and lift arm 2 respectively through the bearing pin mode.
Through stretching of control elevating ram 1, make lift arm 2 rotate along lifting arm axle 7, realize the operation that lift arm 2 lifts (lifting) or puts down.After lift arm 2 liftings arrived set height position, telescopic oil cylinder 3 was started working, and leading block group 5 moves forward at guide rail 9 upper edge lift arms 2, and V-type groove 4 is carried to the well head direction.Realization is transplanted on the ground level position with drill string 6 by well head central vertical position, perhaps the drill string 6 of ground level position is transplanted on the well head center of vertical rig floor face.
Lifting type drilling and repairing machine of the present invention with its operating principle of power cat road is: with reference to Fig. 1, the lifting type drilling and repairing machine that drill string 6 rest on the ground is with on the V-type groove 4 in the power cat road, stretches out through elevating ram 1 to make lift arm 2 around 7 rotations of lifting arm axle; When lift arm 2 front ends rose to height such as rig floor face grade, elevating ram 1 stopped to stretch out, and makes lift arm 2 remain on current location, with reference to Fig. 2.Telescopic oil cylinder 3 is started working then, and telescopic oil cylinder 3 stretches out drive V-type groove 4 and moves to the well head direction along the guide rail on the lift arm 29.In the time of near V-type groove 4 is transferred to drill string 6 one ends at well head, telescopic oil cylinder 3 stops to stretch out, with reference to Fig. 3.At this moment, elevator transferred to rig floor face well head place dock,, drill string 6 is promoted to well head center vertical position, go up the button operation then, accomplish the butt joint of drill string 6, with reference to Fig. 5 with reference to Fig. 4 with drill string 6.Drill string 6 is transferred to the inverse process that the ground level position is above-mentioned method of work from the well head center.
Apparatus of the present invention are mainly used on land oil-well rig and the working rig; When drill string 6 is in rig floor face top; This device is flexible through oil cylinder; " V " type groove is delivered to rig floor face top, utilize machinery or manual type that drill string 6 is placed in " V " type groove, through the flexible of oil cylinder drill string 6 is transferred to the ground level position then.On the contrary, this device also can be transferred to pithead position with the drill string 6 that is in the type groove of ground level position " V ", utilizes automatic elevator and hoisting mechanism to make drill string 6 reach vertical job state, carries out tripping operation.The invention solves the dependence that drilling and repairing machine apparatus for work drill string 6 is carried main equipment, the work that can replace drilling and repairing machine drill string 6 to carry fully; And can effectively improve the efficient that drill string 6 is carried, reduce personnel's labour intensity.Overall structure is simple, and is in light weight, is easy to safeguard, is fit to quick movement.
