[0001] This invention belongs to the field of nuclear power plant suspended platform locking nut removal and installation, specifically relating to a tooling for removing and installing locking nuts and adjusting nuts. Background Technology

[0002] After long-term operation, nuclear power plant equipment may experience reduced reliability or even damage. The locking nuts at the reactor basket location may become loose and worn. If the locking nuts become loose, the adjusting nuts may also become loose and worn, or even shift downwards. Therefore, it is necessary to remove the locking nuts and adjusting nuts in a timely manner and replace them with new ones.

[0003] Existing technology often involves manually operating a torque wrench to remove lock nuts and adjusting nuts, but this is not feasible in the confined space underwater or in high-dose, high-radiation environments. Furthermore, operators cannot remain submerged underwater for extended periods to remove or replace lock nuts and adjusting nuts.

[0004] Therefore, maintenance personnel need to remotely operate specialized tools on shore to remove locking nuts and adjusting nuts and install new locking nuts.

[0005] Therefore, we continue to develop a tooling for removing and installing locking nuts and adjusting nuts suitable for underwater operations in irradiated environments, in order to solve the problems existing in the current technology. Summary of the Invention

Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0032] The present invention provides a tooling for removing and installing locking nuts and adjusting nuts, comprising: a housing 5, an input component, an output component, and a guide component.

[0033] Box 5 is the main structure of the entire fixture, used to install input components, output components, and guide components. Guide components are installed at the top of box 5, and a drainage hole is provided at the bottom to reduce overall weight and facilitate drainage of internal water during hoisting. Box 5 also has four scales 12 for determining the depth of removal and installation of locking nuts and adjusting nuts.

[0034] In one specific embodiment, an underwater camera can be used to observe the contact position between the rotating sleeve 11 and the scale 12 to determine the depth position for removing and installing the locking nut and adjusting nut.

[0035] The input components include: input shaft 1, retaining ring 2, first bushing 3, retaining seat 4, and drive gear 16.

[0036] The first bushing 3 is fixedly connected to the outside of the housing 5. The input shaft 1 passes horizontally through the first bushing 3 and the housing 5. The input shaft 1 is installed on the housing 5. The step on the input shaft 1 contacts the end face of the first bushing 3. The input end of the input shaft 1 is placed outside the first bushing 3, and the output end is placed inside the housing 5. The input end of the input shaft 1 is connected to the long rod tool on the shore. The rotation of the tool on the shore drives the input shaft 1 to rotate. The output end of the input shaft 1 is coaxially mounted with a drive gear 16. The drive gear 16 is installed inside the housing 5. The rotation of the input shaft 1 drives the drive gear 16 to rotate.

[0037] A gap is provided between the input shaft 1 and the first bushing 3. The fixing ring 2 is placed on the outer end face of the first bushing 3. The fixing ring 2 is connected to the input shaft 1 and is used to adjust the gap between the input shaft 1 and the first bushing 3 to limit the axial movement of the input shaft 1.

[0038] The fixing seat 4 is placed on the outer periphery of the first bushing 3 and is fixedly connected to the housing 5 for fixing and limiting the first bushing 3.

[0039] In one specific embodiment, the first bushing 3 is fixedly connected to the housing 5 by screws, and the fixing seat 4 is fixedly connected to the housing 5 by screws; the drive gear 16 is connected by a flat key on the input shaft 1 and fasteners.

[0040] The output components include: a driven gear 17, an upper bushing, a lower bushing, an output shaft 14, a rotating sleeve 11, a disassembly / removal head, a spring 13, a retaining anti-disengagement rod 10, and a small spring 18.

[0041] The lower bushing is fixedly connected to the bottom plate inside the housing 5, and the upper bushing is fixedly connected to the housing 5 through a fixing plate; the output shaft 14 vertically passes through the housing 5, the upper bushing, and the lower bushing, with the upper step of the output shaft 14 contacting the end face of the upper bushing and the lower step of the output shaft 14 contacting the end face of the lower bushing; the upper and lower bushings limit the position of the output shaft 14; the input end of the output shaft 14 is placed inside the housing 5, and the output end is placed outside the housing 5; a driven gear 17 is coaxially installed between the upper and lower steps at the input end of the output shaft 14, and a rotating sleeve 11 is slidably installed at the output end, with the driven gear 17 meshing with the drive gear 16.

[0042] In one specific embodiment, the inner spline of the rotating sleeve 11 is fitted onto the outer spline of the output shaft 14, allowing it to slide axially along the output shaft 14. A positioning screw is provided on the output shaft 14 to limit the sliding distance of the rotating sleeve 11.

[0043] In one specific embodiment, the lower bushing is fixedly connected to the bottom plate inside the housing 5 by screws; the upper bushing is fixedly connected to the fixing plate, and the fixing plate is detachably connected to the housing 5 by screws and the stop; the driven gear 17 is connected to the output shaft 14 by a key.

[0044] The rotation of the drive gear 16 causes the driven gear 17 to rotate, which in turn drives the output shaft 14 and the rotating sleeve 11 to rotate.

[0045] A disassembly head is coaxially fixedly mounted on the rotating sleeve 11; the disassembly head includes a locking nut disassembly head 91 and an adjusting nut disassembly head 92.

[0046] The upper end of the locking nut removal head 91 has a radial protrusion that engages with the radial groove of the locking nut, and the lower end of the locking nut removal head 91 has a radial groove that engages with the radial protrusion of the rotating sleeve 11. The locking nut removal head 91 and the rotating sleeve 11 are fixedly connected by screws. In this way, when the rotating sleeve 11 drives the locking nut removal head 91 to rotate, it falls into the radial groove of the locking nut, thereby realizing the tightening of the locking nut.

[0047] The upper end of the adjusting nut removal and installation head 92 is provided with a radial protrusion that engages with the radial groove of the adjusting nut, and the lower end of the adjusting nut removal and installation head 92 is provided with a radial groove that engages with the radial protrusion of the rotating sleeve 11. The adjusting nut removal and installation head 92 and the rotating sleeve 11 are fixedly connected by screws. In this way, when the rotating sleeve 11 drives the adjusting nut removal and installation head 92 to rotate, it falls into the radial groove of the adjusting nut, thereby realizing the tightening of the adjusting nut.

[0048] A spring 13 is fitted around the output shaft 14. The upper end of the spring 13 contacts the lower end face of the rotating sleeve 11, and the lower end contacts the upper end face of the upper shaft sleeve. The spring 13 can be compressed and springed back. The spring 13 is installed under the rotating sleeve 11 to allow the rotating sleeve 11 to move downward after the tooling enters the bottom plate of the basket and contacts the locking nut and adjusting nut to be removed. On the other hand, it can provide an upward compensating thrust for the rotating sleeve 11 when a new locking nut and adjusting nut are installed.

[0049] The retaining rod 10 is located within the center hole of the output shaft 14. The retaining rod 10 is movably mounted within the output shaft 14, with its top end positioned above the output shaft 14. A small spring 18 is sleeved on the retaining rod 10. The upper end of the small spring 18 contacts the stepped end face of the retaining rod 10 to prevent it from detaching. The lower end of the small spring 18 contacts the end face of the center hole inside the output shaft 14. The retaining rod 10, installed within the center hole of the output shaft 14, prevents the locking nut and adjusting nut from detaching from the fixture during assembly and disassembly.

[0050] In one specific embodiment, a radial set screw is provided on the upper part of the output shaft 14, and an axial flat keyway is provided on the retaining anti-disengagement rod 10. The set screw matches the flat keyway, and the axial movement distance of the retaining anti-disengagement rod 10 is limited by the axial flat keyway on the retaining anti-disengagement rod 10.

[0051] The drive gear 16 is fixedly connected to the outer circumference of the input shaft 1 via a flat key. When the input shaft rotates, the drive gear 16 rotates via the flat key, meshing with the driven gear 17. The driven gear 17 is fixedly connected to the output shaft 14 via a flat key, driving the output shaft 14 to rotate. The output shaft 14 is engaged with the splined shaft or hole of the rotating sleeve 11. While the output shaft 14 drives the rotating sleeve 11 to rotate, the rotating sleeve 11 can move axially along the output shaft 14. The rotating sleeve 11 is engaged with the locking nut removal head 91 or the adjusting nut removal head 92 via a convex and concave tooth profile, so that the rotation of the input shaft 1 can be efficiently transmitted to the locking nut removal head 91 or the adjusting nut removal head 92 in the output section.

[0052] The guiding components include: a pressure plate 7 and a guide cone 8. The pressure plate 7 is fixedly installed on the housing 5, and the guide cone 8 is fixedly installed on the pressure plate 7. The pressure plate 7 is used to withstand the pressure generated when the tooling comes into contact with the bottom plate of the basket after it rises, and the guide cone 8 is used to guide the entire tooling smoothly into the working position.

[0053] In one specific embodiment, the pressure plate 7 is fixedly mounted on the housing 5 with screws via a circular stop, and the guide cone 8 is fixedly mounted on the pressure plate 7 with an arc-shaped stop and screws. The shape of the pressure plate 7 is consistent with the cylindrical diameter of the housing 5; the shape of the guide cone 8 matches the position of the circular hole in the bottom plate of the suspended basket, and its size is slightly smaller than the diameter of the circular hole.

[0054] The tooling of the present invention also includes a lifting joint 6, which is fixedly installed on the housing 5 and is used to connect with lifting tools to facilitate the overall lifting and installation of the tooling.

[0055] The tooling of the present invention also includes a fixing pin 15, which is installed on the bottom plate of the box 5. By using a long-handled tool to screw the fixing pin 15, the locking nut and adjusting nut can be quickly removed and the tooling can be fixedly installed on the transport platform.

[0056] The tooling for removing and installing locking nuts and adjusting nuts provided by this invention is used to remove and install locking nuts and adjusting nuts. The specific process is as follows:

[0057] Lock nut removal process:

[0058] After the fixture is installed and positioned, it rises as a whole. Once the guide cone 8 of the fixture contacts the bottom plate of the suspended platform, the entire device enters the predetermined hole in the bottom plate. The pressure plate 7 fits against the bottom plate. As the fixture rises, the anti-detachment rod 10 remains in contact with the bottom surface of the support column screw of the locking nut. Simultaneously, the anti-detachment rod 10 and the internal small spring 18 are compressed. The locking nut removal head 91 contacts the bottom surface of the locking nut. After rotating the input shaft 1, the locking nut removal head 91 engages with the locking nut. The input shaft 1 rotates in the opposite direction, gradually loosening the locking nut from the support column screw. The rotating sleeve 11 and the locking nut removal head 91 move downwards under the pressure of the loosened locking nut, compressing the spring 13. The rotating sleeve 11 aligns with the lower part of the scale 12. The locking nut is completely disengaged from the support column screw. As the entire fixture descends, the locking nut moves downward and detaches from the support column. Simultaneously, due to the descent of the fixture, the anti-detachment rod 10, under the force of the small spring 18, gradually rises with the descent, ensuring the locking nut remains on the outer periphery of the anti-detachment rod 10 and does not detach from the fixture. Once the entire fixture has completely descended, the locking nut is completely removed.

[0059] Lock nut installation process:

[0060] The locking nut is placed above the locking nut removal head 91, keeping the anti-detachment rod 10 in the upper position under the force of the small spring 18, so that the locking nut surrounds the anti-detachment rod 10 and does not detach from the fixture. The entire fixture is raised, and under the guidance of the guide cone 8, the pressure plate 7 is inserted into the corresponding hole in the bottom plate of the suspended basket. The locking nut, rotating sleeve 11, and locking nut removal head 91 are pressed down, and the rotating sleeve 11 is aligned with the lower edge of the scale 12. At this time, the input shaft 1 is rotated clockwise, and under the force of the spring 13, the locking nut is lifted and gradually screwed into the support column screw until the rotating sleeve 11 is aligned with the upper end of the scale 12, indicating that the locking nut has been tightened in place. The fixture is lowered to the lowest position, the locking nut is disengaged from the fixture, and the guide cone 8 and pressure plate 7 are completely removed from the bottom plate of the suspended basket, completing the installation of the locking nut.

[0061] Adjusting nut removal process:

[0062] After the fixture is installed and positioned, it rises as a whole. Once the guide cone 8 of the fixture contacts the bottom plate of the suspended platform, the entire device enters the predetermined hole in the bottom plate. The pressure plate 7 fits against the bottom plate. As the fixture rises, the anti-detachment rod 10 remains in contact with the bottom surface of the support column screw of the adjusting nut. Simultaneously, the anti-detachment rod 10 and the internal small spring 18 are compressed. The adjusting nut disassembly head 92 contacts the bottom surface of the adjusting nut. After rotating the input shaft 1, the adjusting nut disassembly head 92 engages with the adjusting nut. The input shaft 1 rotates in the opposite direction, gradually loosening the adjusting nut from the support column screw. The rotating sleeve 11 and the adjusting nut disassembly head 92 move downwards under the pressure of the loosening adjusting nut, compressing the spring 13. The rotating sleeve 11 aligns with the lower part of the scale 12. The adjusting nut is completely disengaged from the support column screw. As the entire fixture descends, the adjusting nut moves downward and detaches from the support column. Simultaneously, due to the descent of the fixture, the anti-detachment rod 10, under the elastic force of the small spring 18, gradually rises with the descent, ensuring that the adjusting nut 19 remains on the outer periphery of the anti-detachment rod 10 and does not detach from the fixture. Then, the adjusting nut 19 is clamped and held stationary by a jig. With the entire fixture fully descended, the adjusting nut 19 completely separates from the fixture and is removed using the jig.

[0063] Adjusting nut installation process:

[0064] The adjusting nut 19 is held at its lower end by the gripper and inserted into the hole at the bottom plate of the suspended platform. The gripper maintains the grip, and the adjusting nut removal and installation fixture is lifted. Guided by the guide cone 8, the pressure plate 7 is inserted into the corresponding hole in the bottom plate of the suspended platform. The adjusting nut removal and installation head 92 contacts the groove at the lower end of the adjusting nut 19, keeping the anti-detachment rod 10 in the upper position under the elastic force of the small spring 18, so that the adjusting nut surrounds the anti-detachment rod 10 and does not detach from the fixture. The adjusting nut, rotating sleeve 11, and adjusting nut removal and installation head 92 are pressed down, and the rotating sleeve 11 aligns with the lower edge of the scale 12. At this time, the input shaft 1 is rotated clockwise, and under the elastic force of the spring 13, the adjusting nut 19 is lifted and gradually screwed into the support column screw until the rotating sleeve 11 aligns with the upper end of the scale 12, indicating that the adjusting nut has been tightened in place. The fixture is lowered to the lowest position, the adjusting nut is disengaged from the fixture, and the guide cone 8 and pressure plate 7 are completely removed from the bottom plate of the suspended platform, completing the installation of the adjusting nut.

[0065] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. All contents not described in detail in the present invention can be derived from existing technologies.
