The specific embodiment

Below in conjunction with accompanying

drawing

1,2,3,4,5,6,7,8 a kind of embodiment of the present invention is described.

A kind of oil-well rig mobile device is made up of moving guide rail 1 and push cylinder 2 and hydraulic system 3; Moving guide rail 1 is interconnected by the isometric rail unit 21 of two rows and forms, and is laid on the right and left of well head 20.Each rail unit 21 is made up of follower rail 7 and interior side rails 8, and by connector 9 follower rail 7 and interior side rails 8 is connected and fixed, and uniform two row's stepped aperture 5 on the interior side rails 8.Rig 4 is located on four guide rails of well head 20 the right and lefts.Two cylinder supports 6 are inserted into respectively in the row of two on two interior side rails 8 stepped aperture 5.Cylinder support 6 is made up of plate-like body 9, fixture block 10, four vertical plug-in mountings of fixture block 10 symmetries are weldingly fixed on the Si Jiaochu of plate-like body 9, and the bottom that makes four fixture blocks 10 is inserted in the stepped aperture 5, plate-like body 9 upper surfaces are fixed with a pair of otic placode 11, the cylinder body tail end of push cylinder 2 is hinged on the otic placode 11, and piston end is hinged on the base of rig 4.

Described follower rail 7 is made of i iron I 12 and the steel plate I 13 that is fixed on i iron I 12 upper surfaces, side rails 8 is made of with the steel plate II 15 that is fixed on i iron II 14 upper ends i iron II 14 in described, i iron I 12 and i iron II 14 are connected and fixed by connector 9, and two row's stepped aperture 5 are positioned on the steel plate II 15.

Described fixture block 10 is inclined-plane 16 towards the end face of rig 4, when being convenient to push cylinder 2 retractions it is pulled out from stepped aperture 5, the end face that deviates from rig 4 is a vertical plane 17, and when push cylinder 2 ejected, this end face abutted against four origin of force of the rear end of stepped aperture 5 as cylinder support 6.Described plate-like body 9 is hinged with the anti-pawl 18 that sticks up respectively towards the both sides of rig 4 one ends, and anti-ly sticks up the both sides that pawl 18 is installed on steel plate II 15, the cylinder support 6 leading sections generation potential safety hazard that is upturned when preventing that push cylinder 2 from ejecting.

For the base that reduces rig 4 and the contact area of four guide rails, reduce frictional force when mobile, can be below the base of rig 4 uniform slide plate 19, and slide plate 19 is fixed on the below of rig 4 bases, rig 4 is located on the slide plate 19, and slide plate 19 is located on four moving guide rails.

During use push cylinder 2 is connected with hydraulic system 3.Primer fluid pressing system 3 slowly ejects the piston that is positioned at two push cylinder 2 on two side rails 8 synchronously, promote oil cylinder stroke of base reach of rig 4, after oil cylinder ejects and stops, the anti-pawl 18 that sticks up that is installed on the guide rail both sides is dug and made it to break away from guide rail, by hydraulic system the piston of two push cylinder 2 is slowly bounced back synchronously, after pulling out and make cylinder support 6 to move forward an oil cylinder stroke the stepped aperture 5 of cylinder support 6 from interior side rails 8, be inserted in the stepped aperture 5 corresponding on the interior side rails 8, clamp the anti-pawl 18 that sticks up, make by hydraulic system that the piston of two push cylinder 2 is subsynchronous more slowly to eject, the base that promotes rig 4 oil cylinder stroke that moves forward once more, circulation just can move to rig integral body next pithead position and so forth.The rail unit 21 at the rear portion front portion that moves to also capable of circulation when mobile, the length that constantly prolongs moving guide rail, and then the displacement that prolongs rig.When two push cylinder 2 eject when mobile, if asynchronous should stopping immediately being operated arbitrary oil cylinder separately and make itself and another oil cylinder reach synchronous.Passing speed can be by the choke valve adjustment of hydraulic system.
