Fig. 1 shows the assembly of the locking device 100 of the rotationally movable linear covering tool 200 with the subsea valve operating tool. The locking device 100 is attached to the attached end of the rotationally movable linear covering tool 200. As can be seen from fig. 1, the end of the locking device 100 connected to the valve body is similar in structure to the end connected to the rotationally movable linear covering tool 200.
As shown in fig. 2, the locking device 100 is attached to an interface adapter of a linear coverage tool 200. The linear covering tool 200 specifically includes an interface adapter 2, a master cylinder 3, a piston rod 4, a handle 5, a hydraulic motor 6, and a traveling cylinder 7. Regarding the specific structure and operation principle of the rotational moving type linear covering tool 200, CN201510730784.8 is cited in its entirety, and is not described in detail in this embodiment.
As shown in fig. 3-4, which are perspective views of the locking device 100 of the underwater valve operating tool, it can be seen from fig. 3 that the locking device 100 comprises a connector 11 and an interface adapter 13, the connector 11 is used for being matched and connected with the linear covering tool 200, and the interface adapter 13 is used for being butted with an underwater valve body. A flange retaining plate 11.1 extends from a central position of the end surface 11.2 of the joint 11, and the flange retaining plate 11.1 is adapted to be inserted into an interface adapter of the covering tool 200, thereby completing the docking with the covering tool 200. The end face 11.2 of the adapter 11 is provided with a plurality of threaded holes so that the adapter 11 is fixedly mounted on the end of the locking device body 12 by means of a screw thread. An interface adapter 13 is fixedly connected to an end of the locking device body 12 opposite to the joint 11. A threaded hole is also provided in the locking device body 12 at a position close to the interface adapter 13, and the interface adapter 13 is fixedly attached through the threaded hole.
As shown in fig. 5-6, the locking device 100 further includes a thrust rod 10, a latch 8, and a semicircular clip 14. As shown in fig. 5, the lock device body 12 is a hollow cylindrical rotating body, and the thrust rod 10 is disposed in a cavity of the lock device body 12. The locking device body 12, the interface adapter 13, the joint 11 and the thrust rod 10 are all coaxially installed, and both ends of the thrust rod 10 are respectively sleeved in through holes of the joint 11 and the interface adapter 13. A step is provided near the middle of the thrust rod 10, and an annular groove is provided at a distance from the step. The lock catch 8 is sleeved on the thrust rod 10, and one end of the lock catch 8 abuts against the step of the thrust rod 10. Two semicircular clips 14 are caught on the annular groove of the thrust rod 10, and the two semicircular clips 14 are fastened by bolts, that is, the other end of the locking clip 8 is positioned by the semicircular clips 14. As can be seen from fig. 5, the step is spaced from the annular groove by the width of the locking clip 8 in the axial direction. The catch 8 is axially positioned on the thrust rod 10 by the semi-circular collar 14 and the step of the thrust rod 10, and by such an arrangement, the catch 8 can only rotate around the central axis of the thrust rod 10, but cannot translate axially along the thrust rod 10.
As can be seen from fig. 6, the lock catch 8 includes a lock catch body 8.1, a plug 8.2 and a grip 8.3. The lock catch body 8.1 can move along the inner wall surface of the cavity of the locking device main body 12, and the plug 8.2 is a convex block extending from the lock catch body 8.1 towards the direction far away from the center line CX. One surface of the plug 8.2 facing the joint 11 is a stop surface 8.21, and the hand 8.3 is arranged on the outer end surface of the plug.
Fig. 7 shows a specific structure of the locking device body 12, and the locking device body 12 specifically includes a home position switch 12.1, a second position switch 12.2, and a third position switch 12.3. The travel switches 12.1,12.2,12.3 are slots provided in the outer circumferential wall surface of the lock device body 12, which are arc-shaped slots provided on the outer circumferential surface of the lock device body 12 and occupying an arc length rotating around the center line CX.
The first position switch 12.1 is arranged at the end of the locking device body 12 close to the coupling 11 and extends in the direction of the central axis CX for a distance equal to the first stroke of the valve body. When the latch 8 is located in the first position travel switch 12.1, the latch 8 cannot be rotated by the hand grip 8.3. Fig. 5-6 show the locking catch 8 in the first position switch 12.1, in which the semicircular clip 14 abutting the locking catch 8 rests against the inner side of the connector 11. In this state, the thrust rod 10 is completely retracted into the lock device body 12.
Second gear travel switch 12.2 is located next to first gear travel switch 12.1, and the distance that second gear travel switch 12.2 extends in the direction of center axis CX equals the two-stage stroke of valve body to the arc length of second gear travel switch 12.2 around center axis CX is greater than the arc length of first gear travel switch 12.1. When the thrust rod 10 drives the lock catch 8 to move back from the first-gear travel switch 12.1 and enter the range of the second-gear travel switch, the handle 8.3 rotates the lock catch 8 to enter the second-gear travel switch 12.2, and at the moment, the stop surface 8.21 of the lock catch 8 is tightly attached to the arc locking surface 12.21 of the second-gear travel switch 12.2.
The third gear travel switch 12.3 is adjacent to the second gear travel switch 12.2, and the arc length of the third gear travel switch 12.2 around the central axis CX is greater than the arc length of the second gear travel switch 12.2. When the thrust rod 10 drives the lock catch 8 to retreat from the second-gear travel switch 12.1, the hand grip 8.3 rotates the lock catch 8 to enter the third-gear travel switch 12.2, and at the moment, the stop surface 8.21 of the lock catch 8 is tightly attached to the arc locking surface 12.31 of the third-gear travel switch 12.3.
As can be seen from the above description, the actual function of the travel switches 12.1,12.2,12.3 is to maintain the extended position of the thrust rod 10 in the axial direction. When the thrust rod 10 is pushed out of the home position, the end of the thrust rod 10 close to the interface adapter 13 protrudes beyond the mating end face 13.1. Along with the axial movement of the thrust rod 10, the thrust rod 10 drives the lock catch 8 to enter the position of the second-gear travel switch 12.2, at this time, the plug 8.1 is rotated by a certain angle through the gripper 8.3, so that the plug 8.1 of the lock catch 8 is rotated into the second-gear travel switch 12.2, and the stop surface 8.21 abuts against the circular arc locking surface 12.21 of the second-gear travel switch 12.2, so that the thrust rod 10 is locked at the axial position (the first travel position of the valve body). When the thrust rod 10 further extends, the thrust rod 10 drives the lock catch 8 to enter the position of the third-gear travel switch 12.3, and at this time, the plug 8.1 is rotated by a certain angle so that the plug 8.1 of the lock catch 8 rotates into the third-gear travel switch 12.3, and the stop surface 8.21 abuts against the circular arc locking surface 12.31 of the second-gear travel switch 12.3, so that the thrust rod 10 is locked at the axial position (the second travel position of the valve body).
As shown in fig. 7 to 9, the end surface of the device body 12 to which the contact 11 is attached is provided with a synchronization lever slide groove 15, and the synchronization lever slide groove 15 is provided on the outer wall surface of the lock device body 12 in parallel with the center line CX thereof. Referring to fig. 6, a synchronizing bar 9 is arranged in the synchronizing bar sliding groove 15, the synchronizing bar 9 comprises a long bar and an operating handle 9.1 perpendicular to the long bar, the long bar is completely embedded in the synchronizing bar sliding groove 15, and the operating handle 9.1 extends out of the synchronizing bar sliding groove 15. A through hole is arranged on the joint end surface 11 opposite to the synchronous rod sliding groove 15, the long rod of the synchronous rod 9 can pass through the through hole, and the long rod of the synchronous rod 9 can be controlled to extend out of or retract into the joint end surface 11.2 through the operating handle 9.1. Referring to fig. 1-2, when the connection of the rotary movable type linear covering tool 200 with the locking device 100 of the underwater valve operating tool is completed, the long rod of the synchronizing bar 9 is moved toward the covering tool 200 by the operating handle 9.1 and is inserted into the covering tool 200, thereby completing the synchronous setting with the covering tool 200. With such an arrangement, when the cover tool 200 is rotated, the lock device 100 can be maintained in synchronous rotation with the cover tool 200 by the synchronization lever 9.
further, referring to fig. 2, it can be seen that the locking device 100 is coaxially mounted with the cover tool 200, that is, the thrust rod 10 of the locking device 100 is coaxially mounted with the piston rod 4 of the cover tool 200. After the cover tool 200 is started to inject the oil cylinder 3, the piston rod 4 can eject the thrust rod 10 to the first stroke position and the second stroke position of the valve body.
The working principle of the locking device 100.
The interface adapter 2 of the linear covering tool and the joint 11 of the locking tool can be installed in a rotating fit mode, the L-shaped synchronous rod 9 is pushed into the interface adapter 2, and the linear covering tool and the locking device are connected into a whole under the fixing of the L-shaped synchronous rod.
Before launching, the linear covering tool and the locking device are combined into a whole according to the steps, and then the linear covering tool and the locking device are fixedly connected with the underwater robot ROV, launching is close to the Christmas tree, and under the auxiliary positioning of the underwater robot ROV, the linear covering tool and the locking device are close to the Christmas tree valve and are in butt joint with the coaxial line. The movable oil cylinder 7 pushes the whole front end, the interface adapter 13 is pushed into the valve, and the hydraulic motor 6 rotates to drive the interface adapter 13 to rotate to complete locking matching with the valve. The main oil cylinder 3 of the linear covering tool works, the piston rod 4 advances to push the thrust rod 10 to open the valve, and the manipulator of the ROV operates the gripper 8.3 of the lock catch 8 to rotate clockwise by 60 degrees, so that the plug 8.1 of the lock catch 8 completely enters the second-gear travel switch 12.2, and primary travel locking is completed. If the secondary stroke locking is needed, the piston rod 4 of the linear covering tool is continuously pushed to the secondary stroke of the valve body, the manipulator of the ROV of the underwater robot is used as the gripper 8.3 of the lock catch 8 to rotate 120 degrees clockwise, so that the plug 8.1 of the lock catch 8 completely enters the third stroke switch 12.3, and the secondary stroke locking is completed.
At this time, the valve operating tool can be removed, only the locking device is kept on the valve, and the opening state of the valve can be kept for a long time. The ROV manipulator of the underwater robot operates the L-shaped synchronous rod 9, the L-shaped synchronous rod 9 is withdrawn from the interface adapter 2, the main oil cylinder 3 works, and the piston rod 4 is withdrawn. Because of the limit of the lock catch 8, the position of the thrust rod 10 is kept unchanged, and the valve state is kept unchanged.
The hydraulic motor 6 rotates 45 degrees counterclockwise, which drives the interface adapter 2 to rotate counterclockwise. Since a great pressure (several tons to several tens tons) of the spring inside the valve is applied to the locking device thrust rod 10, a great pressing force and friction force exist between the interface adapter 13 of the locking device and the christmas tree valve according to the principle of force action and reaction force, so that the locking device 100 does not rotate counterclockwise by 45 degrees together with the interface adapter 2. The interface adapter 2 and the locking device joint 11 are unlocked, the movable oil cylinder 7 works, the interface adapter 2 exits from the locking device joint 11, and the underwater robot ROV carries a linear covering tool to evacuate from the valve.
if necessary, the locking device is removed from the valve and the valve is restored to its natural state. The linear covering tool is fixedly connected with the underwater robot ROV, launching is close to the Christmas tree, and the linear covering tool and the Christmas tree valve are in butt joint to a coaxial line under the auxiliary positioning of the underwater robot ROV. The moving oil cylinder 7 works, the interface adapter 2 is pushed into the locking device joint 11, the hydraulic motor 6 rotates clockwise by 45 degrees, and the interface adapter 2 and the locking device joint 11 are locked. The ROV manipulator of the underwater robot operates the L-shaped synchronous rod 9, and pushes the L-shaped synchronous rod 9 into the interface adapter 2. The main oil cylinder 3 works, and the piston rod 4 is pushed to the position of the thrust rod 10. The manipulator operation gripper 8.1 of the ROV rotates anticlockwise to the maximum limit, the main oil cylinder 3 works, and the piston rod 4 retreats to the initial position.
