Specific embodiment
As shown in Figure 1, 2, a rotary shaft 11 is mounted in shell 9 to limit the freedom degree of buckle 10, in buckle 10
There are two torsionsprings 21 to provide certain rotary force to buckle 10 for installation between shell 9.Piston rod 12 and buckle 10 1
It is directly in contact condition, spacer pin 14 limits the initial position of piston rod, to prevent piston rod 12 in the whole process and buckle
10 are detached from and cannot achieve the self-locking function of tool.Hinge seat 16 is fixed on ontology 13 by screw 17, with a positioning pin 18
Piston cylinder 15 is connected on hinge seat 16, such piston cylinder 15 can drive the vertical side of piston cylinder 12 due to 10 rotation of buckle
It is rotated in the case where being rotated up around positioning pin 18.One and piston have been opened above the contact position of shell 9 and piston rod 12
The same slot of 12 diameter of bar, to provide the sufficient space moved on piston rod vertical direction.
As shown in figure 3, engage for the ease of interface 4 with valve port, open that there are four lozenges in 4 front end of interface, not only has
The effect of guiding but also it is able to achieve automatic centering.After interface 4 is engaged with valve port, when torque tool works, in engagement place
Lead between interface 4 and valve port that there are certain angle of deviations due to fit tolerance, can thus damage interface 4 and valve
Mouthful, the service life of the tool is greatly reduced, therefore turn there are 4 cylindrical holes at the angle of interface 4 front end four, can thus kept away
The phenomenon that exempting from the presence due to angle of deviation and damaging interface 4 and valve port.
As shown in Figure 2,4, hydraulic motor retarder 20 is mounted on ontology 13, is realized in axial direction by sealing ring 19
Sealing.Then it loads onto internal spline transmission axle 5 and engages it with 20 output shaft of hydraulic motor retarder.Internal spline transmission axle 5 with
There are two support rings 6 and y-type seal ring 7 to be respectively used to support and sealing between ontology 13.Circle magnetic grid 2 is consolidated with sunk screw 1
It is scheduled in ontology 13, the angular adjustment and control of implementation tool together with external plc control system.Interface 4 and internal spline pass
It passs axis 5 to be meshed, modeling rouge connector 3 fixes interface 4, will mould rouge connector 3 using circumferential equally distributed 8 screws 8
It is connected on ontology 13.Shell 9 is welded on to two sides of ontology using welding technique.It is using screw 22 that handle 23 is fixed
On ontology 13.Thus realize the installation assembly of whole device.
Working principle of the present invention is as follows:
Before use, first hydraulic motor retarder 20 is mounted on ontology 13, realized by sealing ring 19 close in axial direction
Envelope.Then it loads onto internal spline transmission axle 5 and engages it with 20 output shaft of hydraulic motor retarder.In internal spline transmission axle 5 and this
There are two support rings 6 and y-type seal ring 7 to be respectively used to support and sealing between body 13.Circle magnetic grid 2 is fixed with sunk screw 1
In ontology 13, the angular adjustment and control of implementation tool together with external plc control system.Interface 4 and internal spline transmit
Axis 5 is meshed, and modeling rouge connector 3 fixes interface 4, is connected using circumferential equally distributed 8 screws 8 by rouge connector 3 is moulded
It connects on ontology 13.Shell 9 is welded on to two sides of ontology using welding technique.A rotation is mounted in shell 9
Axis 11 buckles 10 freedom degree to limit, and there are two torsionsprings 21 to mention to buckle 10 for installation between buckle 10 and shell 9
For certain rotary force.Piston rod 12 and buckle 10 are constantly in contact condition, and spacer pin 14 limits the initial bit of piston rod
It sets, is detached from and cannot achieve the self-locking function of tool to prevent piston rod 12 in the whole process and buckle 10.It is equipped on shell 9
Through-hole, piston rod 12 pass through through-hole.Hinge seat 16 is fixed on ontology 13 by screw 17, with a positioning pin 18 by piston cylinder 15
It is connected on hinge seat 16, what such piston cylinder 15 can rotate on due to 10 rotation drive 12 vertical direction of piston cylinder of buckle
In the case of around positioning pin 18 rotate.One and 12 diameter one of piston rod have been opened above the contact position of shell 9 and piston rod 12
The slot of sample, to provide the sufficient space moved on piston rod vertical direction.Handle 23 is fixed on ontology 13 using screw 22
Face.
When work, handle 23 is guided and supported with tool with ROV robot first, is moved to by production tree along oil extraction pipeline
It aims on the platform that robot work is set up, the angle of interface, angle is then adjusted by the sensor circle magnetic grid 2 of tool interior
Spend it is consistent with the valve port angle on production tree after, then robot engages it with valve port with tool, while engagement,
The inclined-plane of buckle 10 is being pressed against, buckle 10 is being rotated around rotary shaft 11, due to the position-limiting action of spacer pin 14, after piston rod stress
It can not be retracted into piston cylinder 15, piston cylinder 15 can only be driven to rotate together around positioning pin 18, in the shell for being equipped with cavity
It is rotated vertically in body 9.Buckle 10 is restored to initial position under the action of torsionspring 21 when reaching certain position, in this way
Just the self-locking function of tool is realized.ROV robot is removed after self-locking, can be driven to 20 fuel feeding of hydraulic motor retarder
Internal spline transmission axle 5 and interface 4 rotate.Valve port can be driven to rotate in this way, to turn on or off valve.
When maintenance, ROV robot grasps handle 23, gives 15 fuel feeding of piston cylinder, piston rod 12, which pushes, buckles 10 around rotation
Shaft 11 rotates, and when reaching certain position, tool can be removed along the axial position of tool and be left by ROV robot
Production tree tree body, then tool belt is ashore repaired.
The above is only a preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
