Specific embodiment
As shown in Figure 1, 2, it is mounted with a rotary shaft 11 to limit the free degree of buckle 10 in housing 9, in buckle 10
Two torsionsprings 21 are installed between housing 9 to provide certain revolving force to buckle 10.Piston rod 12 and buckle 10 1
Contact condition is directly in, spacer pin 14 limits the initial position of piston rod, in case piston rod 12 and buckle in whole process
10 depart from and cannot implementation tool auto-lock function.Hinge seat 16 is fixed on body 13 by screw 17, with an alignment pin 18
Piston cylinder 15 is connected on hinge seat 16, such piston cylinder 15 can rotarily drive the vertically side of piston cylinder 12 due to buckle 10
Rotate around alignment pin 18 in the case of being rotated up.One and piston have been opened above the contact position of housing 9 and piston rod 12
The same groove of the diameter of bar 12, to provide the sufficient space moved on piston rod vertical direction.
As shown in figure 3, engaging with valve port for the ease of interface 4, four lozenges are provided with the front end of interface 4, are not only had
The effect of guiding and automatic centering can also be realized.After interface 4 is engaged with valve port, when torque tool works, in engagement place
Cause the presence of certain angle of deviation between interface 4 and valve port due to fit tolerance, can thus damage interface 4 and valve
Mouthful, the service life of the instrument is greatly reduced, therefore turn have 4 cylindrical holes at the angle of interface 4 front end four, thus can keep away
Exempt from the phenomenon that interface 4 and valve port are damaged due to the presence of angle of deviation.
As shown in Figure 2,4, hydraulic motor decelerator 20 is arranged on body 13, is realized on axial direction by sealing ring 19
Sealing.Then load onto internal spline transmission axle 5 to engage it with the output shaft of hydraulic motor decelerator 20.Internal spline transmission axle 5 with
There are two support rings 6 to be respectively used to support and sealing with y-type seal ring 7 between body 13.Circle magnetic coral 2 is consolidated with sunk screw 1
It is scheduled in body 13, the angular adjustment of implementation tool and control together with outside plc control systems.Interface 4 is passed with internal spline
Pass axle 5 to be meshed, modeling fat connector 3 fixes joint 4, using circumferential equally distributed 8 screws 8 fat connector 3 will be moulded
It is connected on body 13.Housing 9 is welded on two sides of body using solder technology.Handle 23 is fixed using screw 22
On body 13.Thus realize the installation assembling of whole device.
The operation principle of the present invention is as follows:
Using front, first hydraulic motor decelerator 20 is arranged on body 13, is realized by sealing ring 19 close on axial direction
Envelope.Then load onto internal spline transmission axle 5 to engage it with the output shaft of hydraulic motor decelerator 20.In internal spline transmission axle 5 and originally
There are two support rings 6 to be respectively used to support and sealing with y-type seal ring 7 between body 13.Circle magnetic coral 2 is fixed with sunk screw 1
In body 13, the angular adjustment of implementation tool and control together with outside plc control systems.Interface 4 is transmitted with internal spline
Axle 5 is meshed, and modeling fat connector 3 fixes joint 4, is connected fat connector 3 is moulded using circumferential equally distributed 8 screws 8
It is connected on body 13.Housing 9 is welded on two sides of body using solder technology.A rotation is mounted with housing 9
Axle 11 is provided with two torsionsprings 21 to carry to buckle 10 limiting the free degree of buckle 10 between buckle 10 and housing 9
For certain revolving force.Piston rod 12 is constantly in contact condition with buckle 10, and spacer pin 14 limits the initial bit of piston rod
Put, in case in whole process piston rod 12 and buckle 10 depart from and cannot implementation tool auto-lock function.It is provided with housing 9
Through hole, piston rod 12 passes through through hole.Hinge seat 16 is fixed on body 13 by screw 17, with an alignment pin 18 by piston cylinder 15
It is connected on hinge seat 16, such piston cylinder 15 can rotarily drive what is rotated on the vertical direction of piston cylinder 12 due to buckle 10
In the case of rotate around alignment pin 18.One and the diameter one of piston rod 12 have been opened above the contact position of housing 9 and piston rod 12
The groove of sample, to provide the sufficient space moved on piston rod vertical direction.Handle 23 is fixed on body 13 using screw 22
Face.
During work, handle 23 is guided and supported with instrument, be moved to by production tree along oil extraction pipeline with ROV robots first
Aim on the platform that robot work is set up, then justify magnetic coral 2 to adjust the angle of interface, angle by the sensor of tool interior
After degree is consistent with the valve port angle on production tree, then robot engages it with valve port with instrument, while engagement,
The inclined-plane of buckle 10 is press against, buckle 10 is rotated around rotary shaft 11, due to the position-limiting action of spacer pin 14, after piston rod stress
Can not return into piston cylinder 15, piston cylinder 15 can only be driven to rotate around alignment pin 18 together, be provided with the shell of cavity
Vertically rotate in body 9.Buckle 10 is returned to into initial position in the presence of torsionspring 21 when certain position is reached, so
Just the auto-lock function of instrument is realized.ROV robots are removed after self-locking, just can be driven to the fuel feeding of hydraulic motor decelerator 20
Internal spline transmission axle 5 rotates with interface 4.Valve port so just can be driven to rotate, so as to open or close valve.
During maintenance, ROV robots grasp handle 23, promote buckle 10 around rotation to the fuel feeding of piston cylinder 15, piston rod 12
Rotating shaft 11 rotates, and when certain position is reached, instrument just can be removed and left by ROV robots along the axial location of instrument
Production tree tree body, then take instrument to on-shore maintenance.
The above is only the preferred embodiment of the present invention, it should be pointed out that:For the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
