The coupling locking cap 20 is fitted on the outer circumference of the cable joint, and the cap 10 is correspondingly positioned above the cable joint. The driving connecting rod 30 is arranged in the cap 10 in a penetrating way and can move relative to the cap 10; the insert-extraction link 40 is inserted into the locking cap 20 and is movable with respect to the locking cap 20.
The embedded connecting rod 40 is used for being inserted into the cable joint, at least one screw rod 50 is arranged on the end face of one end of the embedded connecting rod facing the cable joint, and the screw rod 50 is connected with the embedded connecting rod 40 by rotating the embedded lead sealing gasket in the cable joint. The embedding connecting rod 40 is connected with the driving connecting rod 30, moves along with the driving connecting rod 30, enters and exits the cable joint, and takes out the lead sealing gasket in the cable joint.
Wherein the cap 10 and the locking cap 20 may be of an integral structure or coupled together by a set screw 60 or the like, forming a supporting body of the entire device. The cap 10 and the locking cap 20 are connected by the fixing screw 60, so that the cap and the locking cap can be detached, and the maintenance, the part replacement and the like of the whole device are convenient. The outer peripheral shape of the cap 10 may be a circular shape or a polygonal shape, etc., the outer peripheral shape of the locking cap 20 may be disposed corresponding to the cap 10, and the outer peripheral surfaces of the both may be flush-connected.
The cap 10 is provided with a central through hole 100 penetrating opposite sides thereof for the driving link 30 to movably pass therethrough. The central through hole 100 may further comprise a first hole section 101 and a second hole section 102 axially connected, the first hole section 101 has a larger hole diameter than the second hole section 102, and the transition surface 103 between the first hole section 101 and the second hole section 102 may be an inclined surface or a plane perpendicular to the axial direction of the cap 10. The first hole section 101 is located in one end of the cap 10 near the locking cap 20, and the second hole section 102 is located in the other end of the cap 10 facing away from the locking cap 20.
The locking cap 20 is provided with a cap hole 200 for inserting the connecting rod 40 therein. The cap hole 200 is in opposite communication with the central through hole 100 of the cap 10; specifically, the central through bore 100 communicates with the cap bore 200 with its first bore section 101.
The locking cap 20 may further include a cover plate 21, and a cylinder 22 vertically coupled to one surface of the cover plate 21. The locking cap 20 is connected with the cap 10 through a cover plate 21 and is matched with the periphery of the cable joint through a cylinder 22; the cap hole 200 is provided on the cap plate 21 and communicates with the inside of the cylinder 22. The cover plate 21 may cover the end face of the cable joint when the cylinder 22 is fitted to the outer circumference of the cable joint. Typically, the outer circumference of the cable joint is provided with external threads, and the inner wall of the barrel 22 is provided with internal threads 23 which are adapted to the external threads on the cable joint, so that the locking cap 20 is engaged with and fixed relative to the cable joint by threads.

The drive link 30 has axially opposite first and second ends, and the drive link 30 body is disposed through the second bore section 102 of the central throughbore 100 and threadedly engages the second bore section 102. The first end of the driving link 30 is located in the first hole section 101 of the central through hole 100, and the second end protrudes out of the side of the cap 10 facing away from the locking cap 20 as a movable grip for operating the driving link 30.
As the drive link 30 is rotated either forward or reverse along the second bore segment 102, the drive link 30 is moved back and forth in an axial direction relative to the cap 10 by way of a threaded engagement.
The first hole section 101 of the central through hole 100 provides space for the axial movement stroke of the drive link 30 such that the drive link 30 moves axially relative to the cap 10 by a distance equal to or less than the axial length of the first hole section 101. In order to avoid that the driving link 30 moves too much in the axial direction to be separated from the first hole section 101 and enter the second hole section 102, the outer circumference of the first end of the driving link 30 is provided with a first limiting step 31 protruding radially, and the outer diameter of the first limiting step 31 is larger than the inner diameter of the second hole section 102 and smaller than the inner diameter of the first hole section 101. During the axial movement of the drive link 30, the first limiting step 31 can be brought into a detachable abutment on the transition surface 103 between the first bore section 101 and the second bore section 102. When the first limiting step 31 abuts against the transition surface 103, the driving link 30 is limited to move towards the second hole section 102.
To facilitate the forward or reverse rotation of the drive link 30, the lead gasket spinning device of the present invention further includes a drive cap 70. The driving cap 70 is movably disposed at a side of the cap 10 facing away from the locking cap 20 and fixedly coupled with the driving link 30. Specifically, the driving link 30 is connected with the driving cap 70 at one end (second end) protruding out of the cap 10, and when the driving cap 70 is operated to rotate in a forward direction or a reverse direction (clockwise or anticlockwise), the driving link 30 is driven to rotate in the same direction, the driving link 30 transmits a rotation moment to the inserting link 40, and the inserting link 40 is driven to move back and forth in the axial direction.
The outer periphery of the drive cap 70 is preferably non-circular in configuration, such as polygonal, e.g., hexagonal.
The drive cap 70 and the drive link 30 may be integrally fixed by welding or the like. Alternatively, as shown in fig. 3, the driving cap 70 is provided with a through hole 71, and one end of the driving link 30 protrudes out of the cap 10 and penetrates into the through hole 71, and is penetrated through one end of the driving cap 70 and one end of the driving link 30 by a fixing pin 72 to fix the two relatively. When the drive link 30 and the drive cap 70 need to be separated, only the fixing pin 72 needs to be pulled out.
As shown in fig. 2-3, the extraction link 40 is inserted into the cap hole 200 of the locking cap 20 and is rotatable and movable back and forth in the axial direction with respect to the locking cap 20. The insert-extraction link 40 may have opposite first and second ends in the axial direction, the insert-extraction link 40 body movably disposed within the cap aperture 200 with the first end thereof disposed within the barrel 22 of the locking cap 20 and the second end disposed within the first aperture section 101 of the central through bore 100 and connected to the first end of the drive link 30.
In order to prevent the insert connecting rod 40 from moving too much to be separated from the first hole section 101, the outer periphery of the second end of the insert connecting rod 40 is provided with a radially protruding second limiting step 41, and the outer diameter of the second limiting step 41 is larger than the inner diameter of the cap hole 200 and smaller than the inner diameter of the first hole section 101. During the axial movement of the extraction link 40, the second limit step 41 can be brought into a separate abutment on the surface of the locking cap 20 facing the cap 10. When the second limit step 41 abuts on the surface of the locking cap 20 facing the cap 10, the movement of the insert-extraction link 40 in the direction of the cylinder 22 is restricted.
The screw 50 is disposed on the end surface of the first end of the embedding link 40, and when the embedding link 40 rotates and moves into the cable joint, the screw 50 can rotate along with the embedding link 40 and screw into the lead sealing gasket, so as to connect the lead sealing gasket with the embedding link 40.
For an annular lead gasket, the outer diameter of the screw 50 should be less than the width of the annulus of the lead gasket. Further, the screw 50 is preferably provided in two or more pieces so as to stably connect the lead sealing pad to the insertion link 40 after the lead sealing pad is inserted, thereby preventing the lead sealing pad from being inclined or falling off during the insertion.
The embedded connecting rod 40 and the driving connecting rod 30 can be fixedly connected into a whole or detachably connected in a welding mode or the like according to the arrangement requirement. Preferably, the inserting link 40 is detachably connected to the driving link 30, so that one of them can be replaced.
In the embodiment shown in fig. 3, the first end of the drive link 30 is provided with a protruding connecting rod 32, the connecting rod 32 being axially connected to the first end of the drive link 30. A screw hole 42 matched with the connecting rod 32 is formed in the second end of the embedded connecting rod 40; the connecting rod 32 is threadedly engaged within the threaded bore 42 to connect the insert connecting rod 40 to the drive connecting rod 30.

The embedding and taking connecting rod 40 can be a solid rod piece as a whole, and the screw hole 42 extends from the second end surface of the embedding and taking connecting rod 40 to the inside of the embedding and taking connecting rod 40. The embedded connecting rod 40 can also be provided with a central hole penetrating through the two opposite ends of the embedded connecting rod, so that the embedded connecting rod 40 forms a pipe body; the central bore portion in the second end of the recessed link 40 is threaded to form a threaded bore 42.
The lead sealing gasket screwing device is used for taking out the lead sealing gasket in the cable connector, and is particularly used for taking out the lead sealing gasket in the cable connector of a nuclear instrument in a nuclear power plant.

Wherein, the driving cap 70 is rotated to drive the driving connecting rod 30 to rotate, and the driving connecting rod 30 rotates relative to the cap 10 and moves axially in the direction approaching to the cable joint; the driving connecting rod 30 transfers the rotation moment to the embedding and taking connecting rod 40, drives the embedding and taking connecting rod 40 to move towards the inside of the cable joint relative to the locking cap 20 and the cable joint, drives the screw 50 to contact and screw into the lead sealing gasket, and connects the embedding and taking connecting rod 40 with the lead sealing gasket.
S3, the driving connecting rod 30 is reversely rotated to drive the embedding connecting rod 40 to move in a direction away from the cable joint, and meanwhile, the lead sealing gasket is driven to be separated from the original positioning position or separated from the cable joint.
In the same way, in step S2, by rotating the driving cap 70 in the opposite direction to the rotation direction in step S2, the driving link 30 is driven to rotate reversely and move in the direction away from the cable connector, so as to drive the embedding link 40 to move in the direction away from the cable connector, and the lead sealing gasket moves along with the embedding link and is separated from the original positioning position or is separated from the cable connector.
