The technical problems to be solved in the utility model is to provide a kind of combined type iron driller and spray arrester, iron driller and spray arrester are integrated, structure is significantly simplified, be conducive to reduce equipment gross weight, always take up room, and saved more safety operations space for well head.
For solving the problems of the technologies described above, the utility model provides a kind of combined type iron driller and spray arrester, comprising:
Iron driller, this iron driller has grip finger;
Spray arrester, the box body of described spray arrester comprises two half box bodys that cooperatively interact, described two and half box bodys are arranged symmetrically in the grip finger front end both sides of described iron driller, and are connected with described grip finger both sides respectively by connecting bearing pin;
Two oil cylinders, the first end of described two oil cylinders is separately fixed at the both sides of described grip finger by the first oil cylinder bearing pin, the second end of described two oil cylinders is connected with described two and half box bodys respectively by the second oil cylinder bearing pin, described two oil cylinders drive described two and half box bodys around connection bearing pin rotating opening separately to expose described grip finger, or rotate closed to collect mud.
According to an embodiment of the present utility model, described box body also comprises: seal, is arranged on top and the bottom of described two and half box bodys, so that rotate two and half box body upper-lower seal after closure.
According to an embodiment of the present utility model, described half box body be shaped as semicylinder, described seal is semi-circular plate, is arranged on top and the bottom of two semicylinders.
According to an embodiment of the present utility model, described box body also comprises: weather strip, is arranged on the seam crossing between described two and half box bodys, so that rotate the joint seal between two and half box bodys after closure.
According to an embodiment of the present utility model, described combined type iron driller and spray arrester also comprise: union, is fixed on described two and half box bodys on one of them.
Compared with prior art, the utlity model has following advantage:
The combined type iron driller of the utility model embodiment and spray arrester are in trip-out flow process, iron driller clamp enters after well head operating position, do not need to exit completely again, after clamp shackle finishes, appropriate slow astern set a distance, spray arrester is also brought into operating position, directly drilling rod is wrapped, the mud collect flowing out, has saved original iron driller and has return rear spray arrester completely and just can reach the link of well head, reduce total activity duration, effectively improved operating efficiency.

The specific embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail, but should not limit protection domain of the present utility model with this.
Referring to figs. 1 to Fig. 3, the combined type iron driller of the present embodiment comprises with spray arrester: iron driller 11, spray arrester 12, be connected bearing pin 13, oil cylinder 14 and oil cylinder bearing pin 15.Spray arrester 12 comprises: box body 21, seal 22, weather strip 23 and union 24.
Wherein, box body 21 comprises two half box bodys that cooperatively interact, and is two semicylinders, but is not limited to this in the present embodiment.Correspondingly, seal 22 is two semi-circular plates, is arranged on top and the bottom of two semicylinders.More specifically, two semicylinder inside of spray arrester 2 are provided with up and down 22, two semicylinder two side seams of semicircle ring packing weather strip 23 are installed, and union 24 is fixed on two semicylinders of box body 21 on one of them.
Further, two semicylinders of spray arrester box body 21 are symmetrically arranged in iron driller 11 grip finger front end both sides, and the both sides of box body 21 are also provided with oil cylinder 14 separately.A semicylinder of box body 21 is fixed on to grip finger front end one side of iron driller 11 by connecting bearing pin 13, another semicylinder of box body 21 is fixed on the grip finger front end opposite side of iron driller 11 by connecting bearing pin 13.The first end of two oil cylinders 14 is fixed on iron driller 11 grip finger one sides by the first oil cylinder bearing pin 251, and the second end of two oil cylinders 14 is connected with two semicylinders of box body 21 respectively by the second oil cylinder bearing pin 252.Thus, two oil cylinders 14 can drive two semicylinders around connection bearing pin 13 separately, to rotate respectively.
When iron driller 11, prepare to enter before operating position, two semicylinders of spray arrester box body 21 shrink under drive, around connection bearing pin 13 rotating opening separately at oil cylinder 14; Then, iron driller 11 moves forward, and grip finger enters operating position, and after completing shackle, iron driller 11 slow astern set a distances, take spray arrester 12 to operating position; Two semicylinders of box body 21 stretch out under drive oil cylinder 14, closed around connection bearing pin 13 rotations separately, and drilling rod is wrapped, and start to collect the mud flowing out.Seal 22 and weather strip 23 guarantee that collected mud does not leak.In addition, the mud in spray arrester 12 enters mud pit by the rear tube linear flow of union 24.
As shown in Figure 4, when pulling out of hole operation, spray arrester 12 is open modes; In conjunction with Fig. 1 to Fig. 3, the clamp of iron driller 11 completes after shackle, iron driller 11 is return, and drives spray arrester 12 to enter drilling rod position, and two semicylinders that oil cylinder 14 promotes box bodys 21 rotate closed (structure after closure refers to Fig. 2) around connection bearing pin 13 separately respectively; After closure, box body 21 is wrapped in (as shown in figures 1 and 3) in closed box body 21 by the connection interface of top rod 31 and bottom drilling rod 32; Afterwards, top rod 31 is mentioned, and mud flows out from interface, and owing to there being the sealing of seal 22 and weather strip 23, within mud is collected in spray arrester 12, the mud of the inside passes through the rear tube linear flow of union 24 in mud pit; Afterwards, spray arrester 12 is opened again, and iron driller 11 reaches, start next trip-out operation cycle.
To sum up, the combined type iron driller of the present embodiment and spray arrester become an equipment by original two separate device combinations, be about to be arranged on iron driller equipment after spray arrester equipment optimization, the structure of original spray arrester is significantly simplified, guaranteeing that equipment is used under the prerequisite of function separately, by the gross weight of two kinds of equipment, the always minimizing that takes up room, for well head has saved more safety operation space.
It should be noted that, although the shape of two and half box bodys in the present embodiment be take semicylinder and is described as example, but those skilled in the art are to be understood that, the shape of half box body can also be the shape of other any suitable types, such as cuboid, the box body after closure is also correspondingly cuboid.
Although the utility model with preferred embodiment openly as above; but it is not for limiting the utility model; any those skilled in the art are not within departing from spirit and scope of the present utility model; can make possible change and modification, the scope that therefore protection domain of the present utility model should be defined with the utility model claim is as the criterion.
