Description
Technical field
The present invention relates to the transport of oil-well rig tubing string, is that tubing string carries the important matching component in the equipment.
Background technology
Drilling well need be carried out tubing string and carry between ground and offshore boring island.At present, the tubing string transport mainly contains two kinds, and the one, adopt the lifting equipment of derrick and ground way to carry tubing string, the mode that mainly cooperates winch to draw, drag with manual operations is carried out; Inconvenient operation, efficient is lower, but also has potential safety hazard.The 2nd, adopt the automatic lifting equipment, this equipment need be taken a fixed ramp slideway, attachment rail on the inclined slip between offshore boring island and ground; Tubing string is placed in the specific elevating stage; The orbital motion of elevating stage front end edge inclined slip, the rear end is pushed and lifting by mechanized equipment, when the track of elevating stage front end edge slideway arrives the offshore boring island work plane; Need push through a hydraulic cylinder in the elevating stage rear end; Make the tubing string front end push out the elevating stage outside, so that carry out the operation of clamping drilling rod, the propelling movement of drilling rod is disposable propelling movement; The complex structure of this automatic lifting equipment, complex operation.
Summary of the invention
The objective of the invention is to provide a kind of twin-stage pusher of tubing string simple in structure, convenient to operation for the deficiency that overcomes above-mentioned prior art.
The technical scheme that the present invention adopts is: the sledge slide slideway that is dynamically connected, and the end of slideway is fixedly connected the cylinder body of first hydraulic cylinder, and the top of the axis of the piston of first hydraulic cylinder is fixedly connected the balladeur train lower end, and the end of balladeur train is fixedly connected the cylinder body of second hydraulic cylinder; The balladeur train left and right sides is rotationally connected and is crossed as two rockers of V-type groove, is uniformly distributed with three the 3rd hydraulic cylinders below the every rocker, and the cylinder body of three the 3rd hydraulic cylinders all is rotationally connected with balladeur train, and the axis of the piston of three the 3rd hydraulic cylinders all connects the bottom surface of rocker; Drilling rod is arranged in the V-type groove at two rocker head end positions when carrying, the axis of the piston of second hydraulic cylinder is over against the end of drilling rod.
The present invention need not to utilize inclined slip, simplifies the structure, and drilling rod pushes carrying device through secondary, is convenient on offshore boring island with pipe clamp clamping drilling rod.

Fig. 4 is the work sketch map that drill string is transferred drilling rod turnover apparatus of the present invention;
Fig. 5 is the work sketch map that apparatus of the present invention twin-stage pushes;
Among the figure: 1. first hydraulic cylinder; 2. second hydraulic cylinder; 3. balladeur train; 4. the 3rd hydraulic cylinder; 5. rocker; 6. slideway; 7. drilling rod; 8. input pipe framed bent; 9. efferent duct framed bent.
The specific embodiment
Shown in Fig. 1-3, the present invention includes six the 3rd hydraulic cylinders 4, first hydraulic cylinder 1 and one second hydraulic cylinder 2, two rockers 5, a balladeur train 3 and a slideway 6.Concrete structure is:
Shown in Fig. 1-2, balladeur train 3 is slidingly connected on the slideway 6, can be along the slide on the slideway 6.The cross section of slideway 6 can be designed to I shape, and there are two tracks its left and right sides, top, and balladeur train 3 is along two slide on the slideway 6.The end of slideway 6 is fixedly connected the hydraulic cylinder of first hydraulic cylinder 1; The top of the hydraulic cylinder piston axle of first hydraulic cylinder 1 is fixedly connected balladeur train 3 lower ends; Be fixedly connected the hydraulic cylinder of second hydraulic cylinder 2 on the end of balladeur train 3, second hydraulic cylinder 2 is slided with balladeur train 3 synchronously.Like this, first hydraulic cylinder 1 and second hydraulic cylinder 2 are installed in series and form a hydraulic cylinder group, and the effect of first hydraulic cylinder 1 is to promote the balladeur train 3 and second hydraulic cylinder 2, and the balladeur train 3 and second hydraulic cylinder 2 are slided on slideway 6 synchronously.
5, two rockers of two rockers, 5 composition V-type grooves as shown in Figure 3, that balladeur train 3 the right and lefts are rotationally connected and intersect; Every rocker 5 rectangular in shape along on the length direction of rocker 5, are uniformly distributed with three the 3rd hydraulic cylinders 4 below every rocker 5; Be that the cylinder body that the right and left has six the 3rd hydraulic cylinder 4, the three hydraulic cylinders 4 all is rotationally connected with balladeur train 3, the hydraulic cylinder piston axle of the 3rd hydraulic cylinder 4 is connected with the bottom surface of rocker 5; Rocker 5 can be around balladeur train 3 swings under the effect of the 3rd hydraulic cylinder 4 like this; Rotate a certain angle separately, simultaneously, rocker 5 and balladeur train 3 do as a whole on slideway 6 moving linearly.
The present invention at first need put drilling rod 7 in the present invention before the work of on offshore boring island, carrying drilling rod, shown in a figure of Fig. 4, wherein a rocker 5 is balanced and is horizontal attitude, and drilling rod 7 just is easy to push away from input pipe framed bent 8 and puts to two rockers 5; Then, two rockers 5 under the effect of the 3rd hydraulic cylinder 4, one-tenth V-type groove state as shown in Figure 2; When this device was raised to the suitable height of offshore boring island, shown in a figure of Fig. 5, first hydraulic cylinder 1 at this moment and the hydraulic cylinder piston axle of second hydraulic cylinder 2 were in initial position; Shown in the b figure of Fig. 5; Move forward to the front position of slideway 6 along slideway 6 by first hydraulic cylinder, the 1 promotion balladeur train 3 and second hydraulic cylinder 2; Shown in the c figure of Fig. 5; Hydraulic cylinder piston axle top by second hydraulic cylinder 2 promotes drilling rod 7 through the gap that rocker 5 ends leave, and makes 7 one sections on drilling rod reach rocker 5 outsides through this twice propelling movement, so that the operation of back.So just accomplished the operation of releasing drilling rod 7.
It is the reverse process of up carrying drilling rod 7 that the present invention down carries drilling rod 7 from offshore boring island; In the time of when drilling rod 7 slides into the V-type groove that rocker 5 forms up and down from offshore boring island in, shown in the b figure of Fig. 5, make drilling rod 7 continue to glide concordant with rocker 5 in the hydraulic cylinder piston axle withdrawal hydraulic cylinder of second hydraulic cylinder 2 until the upper end of drilling rod 7 along v type groove; Shown in a of Fig. 5; Make balladeur train 3 slide to the bottom of slideway 6 downwards in the hydraulic cylinder piston axle withdrawal hydraulic cylinder by first hydraulic cylinder 1, at this moment slideway 6 is dropped to ground, shown in the b figure of Fig. 4 by the elevating mechanism effect; The hydraulic cylinder piston axle of three the 3rd hydraulic cylinders 4 on rocker 5 is withdrawn in the hydraulic cylinder; Make a rocker 5 down swing to constant slope, at this moment, drilling rod 7 tumbles on the efferent duct framed bent 9 automatically; So just accomplished the operation of down carrying drilling rod 7.
