(5) embodiment
For example the present invention is done description in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1, the nut storehouse is regulated device for screwing up to the hole and mainly is made up of bearing 1, open and close device 2, accent hole device 3 and spanner seat 4 four major parts.Wherein open and close device 2, accent hole device 3 and spanner seat 4 constitute the nut storehouses.Bearing 1 bearing screwed cap storehouse also navigates to the nut storehouse on the connecting tube, in order to the setscrew nut storehouse; Open and close device 2 is in order to the half nuts storehouse; Transfer hole device 3 to align with flange hole in order to regulate the spanner seat; Spanner seat 4 can be realized stretching and the action of fastening nut.
In conjunction with Fig. 2, bearing mainly comprises: ROV Interface Module 5, folding positioning shaft 6, hydraulic fluid port 7, anchor clamps 8.Bearing 1 is the carrier in whole nut storehouse, is used for the bearing screwed cap storehouse, and it is in occupation of the most of quality and the volume in nut storehouse.The nut storehouse combines with ROV by ROV Interface Module 5, realizes that solid space moves under water.The ROV Interface Module is a common interface module, in order to contact working tool and ROV.Folding positioning shaft 6 is installed in the axis hole with the carrying open and close device.Two oil hydraulic cylinders of anterior baffle plate installed inside of bearing are to drive open and close device 2, and the cylinder bucket of oil hydraulic cylinder is to be installed on the anterior baffle plate of bearing with hinged form.The oil sources common interface module is installed at hydraulic fluid port 7 places, realizes that by it ROV gives nut storehouse fuel feeding.Anchor clamps 8 are in order to the setscrew nut storehouse.
It mainly contains following function nut storehouse bearing: the prop carrier in (1) nut storehouse; (2) combine with the ROV common interface module, realize moving of nut storehouse under water; (3) have buoyancy block on it, alleviate the underwater relative weight in nut storehouse; (4) combine with the oil sources common interface module, realize the ROV fuel feeding; (5) be positioned the connected tube pipeline outer wall.
In conjunction with Fig. 3, open and close device mainly comprises: positioning hole 9, folding oil hydraulic cylinder 10, fulcrum 11, accent hole oil hydraulic cylinder 12, grooved track 13.Positioning hole 9 machining accuracies are higher, and the smooth anti-friction of its internal surface.Second precision in nut storehouse depends on this positioning hole (first precision depends on the anchor clamps in nut storehouse).The folding oil hydraulic cylinder belongs to the 3rd precision, if the folding precision does not reach, nut can not align with bolt too well.Folding oil hydraulic cylinder 10 pulling open and close device integral body are rotated the open and close movement that realizes open and close device around fulcrum 11.Transfer hole oil hydraulic cylinder 12 to be installed on the open and close device realizing aliging of spanner and flange hole, it is connected with driving lever on the device of accent hole.The straight line motion of oil hydraulic cylinder be converted to transfer the hole device around axial rotation.Grooved track 13 has two effects, and one is transferred the driving lever of hole device can run through open and close device and is connected the rotation of realization accent hole device with oil hydraulic cylinder on the open and close device; Its two, transfer the hole device why can be installed on the semicircular open and close device, be because a grooved track is arranged, clamp open and close device with two-layer circular arc tile, formed the radial constraint of transferring hole device and open and close device like this, can circumferential movement, and radially mobile not.In a word, the function of open and close device is to realize the folding in nut storehouse, and cooperates with bearing and accent hole device, finishes other function.
In conjunction with Fig. 4, transfer hole device structure mainly to comprise: outer tile 14, driving lever 15, interior tile 16, feeding hydrocylinder 17, axis hole 18.The radial displacement that hole device and open and close device are transferred in outer tile 14 constraints, its inwall will have very high surface treatment.Interior tile 16 inwalls are installed an oil hydraulic cylinder, and outer wall is done surface treatments such as correct grinding (because it has contacting of sliding friction with open and close device, can be called the 4th influences precision).Outer tile 14 and interior tile 16 are fixed by a bar or rib, guarantee cylindricity and gap between interior tile 16 and the outer tile 14.Open and close device is clipped in and rotates between outer tile 14 and the interior tile 16 to realize transferring the hole process.On the tile 16, an end was connected with the accent hole oil hydraulic cylinder 12 of open and close device in driving lever 15 1 ends were cemented in, and elongated or shortened by the accent hole oil hydraulic cylinder 12 on the open and close device, drove driving lever 15 and swung back and forth, and realized transferring the hole process.There are two axis holes 18 inside of each accent hole device of half, two axles is installed as guide rail, and spanner seat 4 is realized axial moving along this axial guidance.The feeding hydrocylinder 17 of interior tile inwall drives spanner seat 4 along the axial trajectory feeding or retreat.Transfer the hole device in order to realize the alignment of nuts and bolt.Its driving lever is connected with accent hole oil hydraulic cylinder 12 on the open and close device, to realize transferring the rotation of hole device.Generally speaking, the major function of transferring the hole device is the accent hole of realizing the nut storehouse, also can cooperate the auxiliary function that realizes other of open and close device and spanner seat.
In conjunction with Fig. 5, spanner seat 4 is nut storehouse most important parts, the motion of bearing tensile bolt and finally tighting a bolt.It mainly is made up of spanner storehouse 19, spanner 20 and oil hydraulic cylinder seat 21.Oil hydraulic cylinder seat 21 be installed on the spanner storehouse 19 and the spanner storehouse fixed, eight oil hydraulic cylinders are installed in the oil hydraulic cylinder seat, be used for tensile bolt.Assembly wrench 20 in the spanner seat spanner storehouse, it is a special spanner, and each spanner storehouse of half is equipped with eight spanners, and spanner 20 is connected by coupling with oil hydraulic cylinder seat 21 interior oil hydraulic cylinders, forms a stretching impact wrench device.Moving vertically by external feeding hydrocylinder 17 in spanner storehouse 19, realizes the axial feed of whole spanner seat 4.
To sum up, it is to be used for adjusting nut to align with corresponding bolt axle center that the nut storehouse mainly acts on, the device of fastening nut afterwards, and it has five elementary processes:
(1) clamp, the location of initial tract is a clamping process, and action is realized clamping by the anchor clamps on the bearing 8 in whole nut storehouse.This process is the first step of nut storehouse work, navigates on the pipeline outer wall by the self poisoning device, realizes that nut storehouse Primary Location is to the pipeline outer wall that is welded with fastening flange one side.
(2) folding, opening and closing movement is finished by folding oil hydraulic cylinder 10 on the bearing and open and close device 2, opens and the open and close device that closes by stretching of oil hydraulic cylinder.This is second step of nut storehouse work, and it to pipeline, is arranged on the circumference 16 spanners 20, realizes that nut is screwed into.
(3),,, will equivalence be to transfer the hole device around the certain angle of axial rotation as long as oil hydraulic cylinder elongates or shortens certain distance by transferring hole oil hydraulic cylinder 12 and driving lever 15 to finish jointly to the hole action to the hole.This is the 3rd step of nut storehouse work, and it is spanner 20 and flange hole alignment, and briefly this is rotatablely moving of an open and close device 2.
(4) feeding, the feeding of spanner seat 4 axial feeds to guarantee that nut is screwed into, it transfers the stretching of feeding hydrocylinder 17 of device inboard, hole to realize the feeding of spanner seat by being installed in.This process is the 4th step of nut storehouse work, and it is mainly used to feed nut, as long as feed speed and the nut speed that is screwed into that guarantees equates.
(5) tighten, finally realize tightening of nut by the special spanner in the spanner seat 4.
