Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] In the description of the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of such features.

[0032] In the description of the present application, “a plurality of” means at least two, for example, two, three, etc., unless otherwise clearly defined.

Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0036] In the description of this application, it should be noted that the term "and / or" is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone.

[0037] It should also be noted that, in the embodiments of the present application, the same figure mark represents the same component or the same part. For the same parts in the embodiments of the present application, the figure may only mark one of the parts or components as an example. It should be understood that the figure mark also applies to other identical parts or components.

[0038] During the maintenance of a nuclear power plant, when components on a pressure vessel need to be disassembled, they usually require the use of guide columns for guided removal. After the components are removed from the pressure vessel, the guide column also needs to be removed from the pressure vessel. However, during the actual removal of the guide column, after the guide column is connected to the guide column disassembly tool, the guide column disassembly tool and the guide column are lifted away from the pressure vessel together by a crane. The guide column disassembly tool includes a connected latch connection mechanism and a rotation mechanism. The crane moves the guide column disassembly tool to the position of the guide column, and then drives the latch mechanism to rotate through the rotation mechanism so that the plug-in direction of the guide column's lifting ring latch mechanism matches. The latch mechanism's latch pin is then inserted into the guide column's lifting hole, and then the lifting operation is performed. During the process of removing the guide column, it is usually necessary to manually operate a hand chain hoist to achieve the lifting distance of the guide column disassembly tool. Manual operation of the hand chain hoist is time-consuming and labor-intensive, and is not conducive to accurate control of the guide column lifting distance.

[0039] Based on this, an embodiment of the present application provides a guide column disassembly and assembly tool, which has a lifting mechanism. The lifting mechanism is used to mechanically lift the guide column, and mechanical operation is used to replace manual operation, which is beneficial to improving the disassembly efficiency of the guide column and also beneficial to improving the accurate control of the lifting distance of the guide column.

[0040] The following combination Figures 1 to 11 The guide post disassembly and assembly tool 100 according to the embodiment of the present application is described.

[0041] In some embodiments, see Figures 1 to 4As shown, the guide post disassembly and assembly tool 100 is used to connect with the guide post. The guide post disassembly and assembly tool 100 includes a lifting mechanism 10, a rotating mechanism 20 and a latch connection mechanism 30; the lifting mechanism 10 includes a mounting base 11, a lifting drive member 12 and a lifting member 13, the lifting drive member 12 is connected to the mounting base 11, the lifting drive member 12 is connected to the lifting member 13, and the lifting drive member 12 is used to drive the lifting member 13 to move up and down; the rotating mechanism 20 includes a connecting base 21 and a rotating drive member 22. The rotating drive member 22 is connected to the connecting base 21, and the connecting base 21 is connected to the lifting member 13; the pin connecting mechanism 30 includes a fixed base 31, a pin driving member 32 and a pin 33, the fixed base 31 is connected to the rotating drive member 22, the rotating mechanism 20 is used to drive the fixed base 31 to rotate, the pin driving member 32 is connected to the fixed base 31, the pin driving member 32 is connected to the pin 33, and the pin driving member 32 is used to drive the pin 33 to move so as to be inserted into the guide ring of the guide column.

[0042] A guide column may refer to a component used to provide guidance for a disassembly component on a pressure vessel. In some examples, before the disassembly component is disassembled, the guide column is connected to the pressure vessel, and the guide column is passed through a guide hole of the disassembly component. During the disassembly process of the disassembly component, the guide column provides guidance for the disassembly movement of the disassembly component, thereby improving the stability of the disassembly of the disassembly component and reducing the risk of damage to the disassembly component and the pressure vessel.

[0043] In some examples, the guide column includes a column body and a guide ring. The column body is used to be inserted into the pressure vessel and the disassembly component for guidance; the guide ring is connected to one end of the column body, and the guide ring is used to connect with the pin connection mechanism 30, thereby realizing the connection between the guide column disassembly tool 100 and the guide column, making it convenient for the guide column disassembly tool 100 to remove the guide column from the pressure vessel.

[0044] The lifting mechanism 10 may refer to a component for driving the rotating mechanism 20 and the latch connection mechanism 30 to move up and down. The lifting mechanism 10 may be a cylinder or a linear module.

[0045] The mounting base 11 may be a component that provides a mounting location for the lifting mechanism 10. The mounting base 11 can be connected to a crane, enabling the crane to move the guide post removal tool 100 to the guide post to be removed, thereby connecting with the guide post and subsequently removing or installing the guide post from the pressure vessel. The mounting base 11 can have various shapes, such as a frame structure or a columnar structure. For example, the mounting base 11 is the shell structure of the lifting mechanism 10.

[0046] The lifting drive 12 may refer to the power component of the lifting mechanism 10, and the lifting component 13 may refer to the component that can be lifted and lowered relative to the mounting base 11. The lifting drive 12 may be a motor or other component, and the lifting component 13 may be a screw, nut or slide or other component.

[0047] The rotating mechanism 20 may refer to a component for driving the latch connection mechanism 30. The rotating mechanism 20 drives the latch 33 of the latch connection mechanism 30 to be plugged in so as to match the inner hole of the guide ring. For example, the axis of the latch 33 is parallel or nearly parallel to the axis of the inner hole of the guide ring, so as to facilitate the insertion of the latch 33 into the inner hole of the guide ring, thereby realizing the connection between the guide column and the guide column disassembly and assembly tool 100.

[0048] The rotating mechanism 20 includes a connecting base 21 and a rotating drive member 22. The rotating drive member 22 is connected to the connecting base 21. The rotating drive member 22 can refer to a component that drives the pin connection mechanism 30 to rotate. The connecting base 21 can refer to a component that provides an installation position for the rotating drive member 22, which plays a role in supporting the rotating drive member 22. For example, the connecting base 21 is the shell structure of the rotating mechanism 20. In addition, the connecting base 21 can also play the role of connecting the lifting member 13 and the rotating drive member 22, so that when the lifting member 13 is raised or lowered, it can drive the connecting base 21, the rotating drive member 22 connected to the connecting base 21, and the pin connection mechanism 30 connected to the rotating drive member 22 to rise and fall, thereby realizing the lifting and lowering of the guide column. The connecting base 21 can have various shapes, such as a frame structure, a columnar structure, etc. The rotating drive member 22 can be a component such as a motor.

[0049] The latch connection mechanism 30 may be a component that plugs into and mates with the guide eye of the guide column. It includes a fixed base 31, a latch driver 32, and a latch 33. The latch driver 32 may be a component that drives the latch 33 along its axis. The latch driver 32 may be an electric push rod, a cylinder, a linear module, or other components. The latch 33 may be a cylindrical shaft, a stepped shaft, or other components. For example, the fixed base 31 is the housing structure of the latch connection mechanism 30.

[0050] The guide post disassembly and assembly tool 100 of the embodiment of the present application is used. When the guide post disassembly and assembly tool 100 is used, the guide post disassembly and assembly tool 100 can be moved to the position of the guide post to be disassembled by using a crane. Then, the rotary drive member 22 drives the latch connection mechanism 30 to rotate, so that the latch 33 in the latch connection mechanism 30 cooperates with the guide lifting ring of the guide post. Then, the lifting drive member 12 of the lifting mechanism 10 drives the lifting member 13 to descend, thereby driving the rotary mechanism 20 and the latch connection mechanism 30 to descend. When the latch 33 is arranged opposite to the inner hole of the guide lifting ring, the latch drive member 32 drives the latch 33 to move, so that it is inserted into the guide lifting ring, thereby achieving the connection between the guide post disassembly and assembly tool 100 and the guide post. Finally, the guide post disassembly and assembly tool 100 and the guide post are removed from the pressure vessel by using a crane to achieve the removal of the guide post. The guide post disassembly and assembly tool 100 of the embodiment of the present application directly uses the lifting drive member 12 to drive the lifting member 13 to rise and fall. In this way, mechanical operation replaces manual operation, which is conducive to improving the removal efficiency of the guide post and also conducive to improving the accurate control of the lifting distance of the guide post.

[0051] It is understandable that the installation of the guide column can refer to the reverse process of the above-mentioned disassembly process, which will not be described in detail here.

[0052] In some embodiments, the lifting mechanism 10, the rotating mechanism 20 and the latch connection mechanism 30 are distributed along a vertical straight line. Such a distribution is conducive to the connection of components, and can also reduce the generation of torque during the lifting process and improve the stability of the guide column lifting.

[0053] In some embodiments, please refer to Figure 3 、 Figure 5 and 6 As shown, the lifting mechanism 10 includes a planetary roller screw 14, and the lifting drive 12 is connected to the nut 142 of the planetary roller screw 14. The lifting drive 12 is used to drive the nut 142 of the planetary roller screw 14 to rotate around its own axis. One end of the screw rod 141 of the planetary roller screw 14 is connected to the connecting base 21, and the screw rod 141 of the planetary roller screw 14 forms a lifting member 13.

[0054] The planetary roller screw 14 includes a screw rod 141, a nut 142 and planetary rollers. The outer surface of the screw rod 141 is provided with an external thread. The nut 142 is sleeved on the outside of the screw rod 141. The nut 142 is provided with an internal thread. There are multiple planetary rollers, which are evenly distributed along the circumference of the screw rod 141 and located between the screw rod 141 and the nut 142. The outer surface of each roller is provided with an external thread that is threadably engaged with the screw rod 141 and the nut 142.

[0055] When the lifting drive component 12 (for example, a servo motor, a hydraulic motor, etc.) drives the nut 142 to rotate around its own axis, the planetary rollers perform planetary motion between the screw rod 141 and the nut 142. The planetary rollers revolve around the axis of the screw rod 141 and rotate around their own axes. The rotation of the planetary rollers causes their threads to roll relative to the threads of the screw rod 141 and the nut 142, thereby converting the rotational motion of the nut 142 into linear motion of the screw rod 141, causing the screw rod 141 to rise and fall along its own axis without the screw rod 141 itself rotating. The rise and fall of the screw rod 141 drives the guide column to rise and fall.

[0056] The lifting drive 12 directly drives the nut 142 to rotate instead of the screw rod 141. The power input point is the nut 142, which helps to reduce the space required for the screw rod 141 to rotate and improve the structural compactness of the lifting mechanism 10.

[0057] One end of the screw rod 141 is rigidly fixed to the connecting base 21 of the rotating mechanism 20. The screw rod 141 drives the connecting base 21, and the connecting base 21 drives the rotating mechanism 20 and the latch connecting mechanism 30 to rise and fall; the nut 142 drives the screw rod 141 to move along its own axial direction to form the lifting member 13.

[0058] By adopting the technical solution of this embodiment, the planetary roller screw 14 has many advantages such as high precision, high efficiency, and high load, which is conducive to improving the accurate control and use reliability of the guide column lifting.

[0059] In some embodiments, please refer to Figure 3 、 Figure 5 and 6 As shown, the lifting drive component 12 includes a first frameless motor 121 and a first harmonic reducer 122. The first frameless motor 121 is connected to the mounting base 11. The first frameless motor 121 is connected to the nut 142 of the planetary roller screw 14 through the first harmonic reducer 122. The first frameless motor 121 is used to drive the nut 142 of the planetary roller screw 14 to rotate around its own axis. The screw 141 of the planetary roller screw 14 is passed through the first frameless motor 121 and the first harmonic reducer 122.

[0060] The first frameless motor 121 can be a frameless motor. A frameless motor is a "bare metal" structure that removes the traditional motor housing and shaft, leaving only the stator and rotor. Frameless motors offer advantages such as small size, high power density, and high speed, which facilitates the compactness of the lifting mechanism 10 and the precise control of the guide column's elevation.

[0061] The first harmonic reducer 122 may be a harmonic reducer. A harmonic reducer is a transmission component based on a flexible gear transmission that uses a wave generator to induce controllable elastic deformation of the flexspline, achieving high-precision, low-backlash reduction transmission. Harmonic reducers offer advantages such as a small size and high output torque, which facilitates the compactness of the lifting mechanism 10 and the precise control of the guide column's elevation.

[0062] During use, after the first frameless motor 121 is powered on, the rotor rotates at high speed, driving the input end (usually a wave generator) of the first harmonic reducer 122 to rotate, and the output end of the first harmonic reducer 122 is connected to the nut 142, thereby driving the nut 142 to rotate around its own axis, thereby realizing the lifting and lowering movement of the screw rod 141.

[0063] The screw rod 141 of the planetary roller screw 14 is passed through the first frameless motor 121 and the first harmonic reducer 122 . It can be understood that the screw rod 141 passes through the center hole of the first frameless motor 121 and the center hole of the first harmonic reducer 122 in sequence.

[0064] By adopting the technical solution of this embodiment, the screw 141 is interposed between the first frameless motor 121 and the first harmonic reducer 122, forming a coaxial integrated structure. This reduces the space occupied by the lifting mechanism 10 and facilitates a more compact guide post assembly and removal tool 100. The coaxial integrated structure of the lifting mechanism 10 places the entire center of mass of the guide post assembly and removal tool 100 on the axis of the screw 141, reducing eccentric loads and bending moments in the transmission path and improving the accuracy of lift height control.

[0065] In some embodiments, see Figure 3 and Figure 7 As shown, the first frameless motor 121 is provided with an electromagnetic brake 1211, and a trigger sleeve 1411 is provided on one end of the screw rod 141 of the planetary roller screw 14 facing away from the first harmonic reducer 122. The lifting mechanism 10 also includes a floating trigger device 15, which includes an elastic member 151, a trigger sensor 152 and a trigger plate 153. The trigger sensor 152 is installed on the first frameless motor 121, and the trigger plate 153 is located on the side of the first frameless motor 121 facing away from the first harmonic reducer 122. The elastic member 151 is located between the trigger plate 153 and the first frameless motor 121, and the trigger plate 153 is located between the trigger sleeve 1411 and the first frameless motor 121. The trigger sleeve 1411 is used to counteract the trigger plate 153 to compress the elastic member 151, thereby triggering the trigger sensor 152; the trigger sensor 152 is electrically connected to the electromagnetic brake 1211.

[0066] The electromagnetic brake 1211 locks the motor shaft through electromagnetic force, thereby stopping the lifting of the screw rod 141.

[0067] The elastic member 151 may refer to a component with a certain elasticity. The elastic member 151 may be a spring. The elastic member 151 is located between the trigger piece 153 and the first frameless motor 121 , so that the trigger piece 153 can "float" relative to the first frameless motor 121 , so that the trigger piece 153 has a certain displacement buffer space.

[0068] The trigger sensor 152 may refer to a component for detecting the displacement of the trigger piece 153 . The trigger sensor 152 may be, but is not limited to, a proximity switch or the like.

[0069] The trigger piece 153 can refer to a component that is movably installed on the side of the first frameless motor 121 facing away from the first harmonic reducer 122. The trigger piece 153 can be movably installed on the first frameless motor 121 by means of bolts and other components. Under the elastic force of the elastic member 151, a gap is formed between the trigger piece 153 and the first frameless motor 121.

[0070] The trigger sleeve 1411 may refer to a component that is sleeved on the end of the screw rod 141 facing away from the first frameless motor 121 . The trigger sleeve 1411 may be screwed onto the end of the screw rod 141 to be connected to the screw rod 141 .

[0071] In some cases, the stopping of the first harmonic reducer 122 is delayed, which may result in the failure to stop in time when the screw rod 141 moves to the lower limit position. In the embodiment of the present application, a floating trigger device 15 and a trigger sleeve 1411 are provided. When in use, the first frameless motor 121 drives the nut 142 of the planetary roller screw 14 to rotate, and the screw rod 141 is lifted and lowered through thread transmission. The trigger sleeve 1411 moves with the screw rod 141. At this time, the trigger plate 153 is kept relatively stationary with the first frameless motor 121 through the elastic member 151, the trigger sensor 152 is not activated, the electromagnetic brake 1211 is in a released state, and the first frameless motor 121 is free to move. Rotation; before the screw rod 141 is about to move to the lower limit position, the trigger sleeve 1411 moves with the screw rod 141 and abuts against the trigger plate 153, pushing the trigger plate 153 to move toward the first frameless motor 121, and the trigger plate 153 compresses the elastic part 151. When the displacement of the trigger plate 153 reaches the trigger threshold, the trigger sensor 152 detects the signal, and the trigger sensor 152 transmits the signal to the electromagnetic brake 1211, so that it is immediately energized to lock the motor shaft of the first frameless motor 121, forcing the screw rod 141 to stop moving, thereby timely cutting off the power of the first harmonic reducer 122, reducing the risk of mechanical overload, collision or tripping due to excessive lifting.

[0072] In some embodiments, the electromagnetic brake 1211 is built into the first frameless motor 121, and the trigger sleeve 1411, the trigger plate 153, the first frameless motor 121, the first harmonic reducer 122 and the nut 142 are arranged in sequence along the axis of the screw rod 141, which is conducive to improving the structural compactness of the device.

[0074] The first guide sleeve 111 may be a component that is mounted outside the lifting drive member 12 and the lifting member 13. For example, the planetary roller screw 14, the first frameless motor 121, and the first harmonic reducer 122 are installed in the first guide sleeve 111. The screw rod 141 of the planetary roller screw 14 is coaxially arranged with the first guide sleeve 111 to facilitate the installation of the components.

[0076] The lifting direction of the lifting member 13 is parallel to the axial direction Z of the first guide sleeve 111. When the first lifting drive member 12 drives the lifting member 13 to lift, the lifting member 13 drives the second guide sleeve 211 and the rotating drive member 22 to lift along the axial direction Z of the first guide sleeve 111.

[0077] By adopting the technical solution of this embodiment, the first guide sleeve 111 and the second guide sleeve 211 are movably sleeved, which can guide the lifting of the lifting member 13, making the lifting stability and reliability of the guide column better.

[0078] In some embodiments, a first guide protrusion 1111 is provided on the outer wall of the first guide sleeve 111, and a first guide groove 2111 is provided on the inner wall of the second guide sleeve 211. The first guide protrusion 1111 extends along the axial direction Z of the first guide sleeve 111. During the lifting process of the lifting member 13, the first guide protrusion 1111 moves in the first guide groove 2111, thereby guiding the lifting of the lifting member 13, so that the lifting stability and reliability of the guide column are better.

The tension sensor 115 is clamped between the first flange 112 and the fixing sleeve 114.

[0080] The first flange 112 may refer to a component for connecting the first guide sleeve 111 and the mounting ring 113. The first flange 112 provides support for the mounting ring 113.

Of course, in other examples, the first flange 112 may also be a structure of other shapes.

[0081] The mounting ring 113 may refer to a ring for connecting to a crane. The mounting ring 113 may be a ring bolt or a lifting ear. The mounting ring 113 may be connected to the crane through a lifting rope, a lifting hook or other components to achieve position movement of the guide column disassembly and assembly tool 100.

[0082] The fixing sleeve 114 can refer to a component used to fix the mounting ring 113 to the first flange 112. After one end of the mounting ring 113 passes through the first flange 112 and extends into the first guide sleeve 111, it is fixedly connected to the fixing sleeve 114. Under the blocking effect of the fixing sleeve 114, the mounting ring 113 cannot be separated from the first flange 112, thereby realizing a fixed connection between the mounting ring 113 and the first flange 112. The mounting ring 113 and the fixing sleeve 114 can be connected by means of threads, clamping, bonding, etc.

[0083] The tension sensor 115 may be a pressure sensor. It is sandwiched between the fixing sleeve 114 and the first flange 112. When the crane hoists the mounting eye 113, the weight of the guide post and the guide post assembly and disassembly tool 100 compresses the tension sensor 115, thereby obtaining the real-time load of the guide post assembly and disassembly tool 100 and providing data for the operation and control of the guide post assembly and disassembly tool 100. For example, after the latch connection mechanism 30 is engaged with the guide post, the guide post provides a certain supporting force to the guide post assembly and disassembly tool. At this time, the tension sensor 115 detects a decrease in tension and, based on the reduced tension value, determines whether the guide post assembly and disassembly tool has been lowered into place.

[0086] In some embodiments, the guide post assembly and disassembly tool 100 further includes a control assembly 40, which includes a control module 41 and a power module 42. The power module 42 and the control module 41 are respectively electrically connected to the lifting drive 12, the rotation drive 22, the latch drive 32, and other components to supply power to and control the movement of each component to achieve accurate lifting of the guide post. The control module 41 can be equipped with a wireless communication module and a wired communication module, so that the guide post assembly and disassembly tool 100 can support both wireless and wired control to cope with different working scenarios.

[0087] In some embodiments, the power module 42 is located in the first guide sleeve 111 and is arranged around the outside of the screw rod 141. The power module 42 is located between the first flange 112 and the first frameless motor 121. The control module 41 is installed between the power module 42 and the first flange 112. This distribution can make full use of the space in the first guide sleeve 111 and improve the structural compactness of the guide column disassembly and assembly tool 100. In addition, the power module 42 is arranged around the outside of the screw rod 141, which is conducive to the entire center of mass of the guide column disassembly and assembly tool 100 being on the axis of the screw rod 141, reducing the off-load and bending moment during the movement of the guide column disassembly and assembly tool 100, and improving the accuracy of the movement of the guide column disassembly and assembly tool 100.

The first accommodating cavity 3131 is a flat cavity. The shape of the first accommodating cavity 3131 matches the shape of the circular portion of the guide ring. After the guide ring is inserted into the first accommodating cavity 3131, the guide ring will not rotate, thereby allowing the latch 33 to be stably inserted into the guide ring and achieve connection between the guide post assembly and disassembly tool 100 and the guide post.

[0101] The laser positioning part 342 can refer to a component for emitting laser. The laser emitted by the laser positioning part 342 is irradiated onto the guide ring as a marking point. In this way, when the guide column disassembly and assembly tool 100 is located above the guide column, the laser can be used to determine whether the first accommodating cavity 3131 of the guide column disassembly and assembly tool 100 is aligned with the guide column, so as to facilitate the subsequent guide ring to be accurately inserted into the first accommodating cavity 3131; for example, the laser positioning part 342 can emit a cross laser to better determine the position of the guide ring.

[0102] The camera 341 can be used to obtain images of the guide ring and the laser irradiated on the guide ring, so that based on the positional relationship between the laser and the guide ring in the image, it can be determined whether the first accommodating cavity 3131 of the guide column disassembly and assembly tool 100 is aligned with the guide column.

The second accommodating cavity 3141 is a tapered cavity with a diameter that gradually decreases from bottom to top. The tapered cavity has inclined walls that mate with the inclined surface of the guide post end, thereby guiding the guide ring into the first accommodating cavity 3131.

[0108] By adopting the technical solution of this embodiment, the second accommodating cavity 3141 can guide the guide ring of the guide column to be inserted into the first accommodating cavity 3131, thereby reducing the difficulty of the guide ring of the guide column entering the first accommodating cavity 3131.

[0109] In some embodiments, the fixed base 31 includes a connecting sleeve 311, a fourth flange 312, a fixing seat 313 and a guide cover 314.

[0111] For example, there are two circular arc plates 3111 , which are semi-circular arc plates. The two semi-circular arc plates are spliced ​​together to form a cylindrical connecting sleeve 311 .

[0112] In some embodiments, the rotating mechanism 20 includes a latch sensor, which is used to detect the position of the latch 33. The latch sensor can be a limit switch or the like.

[0113] The use process of the guide post disassembly and assembly tool 100 of the embodiment of the present application is as follows: Remove the guide post disassembly tool 100 from the transport box and check the pre-tightening of the bolts and other components on the guide post disassembly tool 100 to ensure that the guide post disassembly tool 100 is not damaged; Before using the guide post disassembly and assembly tool 100, you can first conduct a comprehensive inspection and functional simulation test on the guide post disassembly and assembly tool 100 to confirm that the guide post disassembly and assembly tool 100 is in a usable state. Specifically, this can include confirming both wireless and wired usage states; After confirming that the guide post removal tool 100 is in a usable state, connect the installation ring 113 of the guide post removal tool 100 to the hook or hook of the crane so that the guide post removal tool 100 does not hit surrounding personnel or equipment. Check that the power switch of the guide post removal tool 100 is in the off state when it is not connected; Turn on the power switch on the guide post disassembly and assembly tool 100, and the power indicator light of the guide post disassembly and assembly tool 100 turns green, so that the electrical equipment in the guide post disassembly and assembly tool 100 is in a standby state; Operate the crane to move the guide post disassembly tool 100 directly above the guide post. Use the cross-line laser emitted by the laser positioning member 342 to align the guide post disassembly tool 100 with the guide post at a distance in the vertical axis direction. The driving control guide column disassembly tool 100 is slowly lowered to a suitable height, and the guide column position is further identified through the guide cover 314 and the camera 341 at the bottom of the guide column disassembly tool 100; The remote control assembly 40 drives the rotary drive member 22 to rotate the latch connection mechanism 30 of the guide post disassembly and assembly tool 100, thereby completing the position recognition between the guide post disassembly and assembly tool 100 and the guide ring of the guide post; Through the use of fill light 343 and camera 341, after the guide post assembly and disassembly tool 100 and the guide ring have completed position recognition, the operation control component 40 drives the lifting drive 12 to cause the tool latch connection mechanism 30 to continue to slowly descend, so that the guide cover 314 falls on the upper part of the guide post and fits the guide post. At this time, the degree of fit between the guide cover 314 and the guide post can be determined based on the data fed back by the tension sensor 115 on the upper part of the guide post assembly and disassembly tool 100. The better the fit, the smaller the value obtained by the tension sensor 115, and the smaller the data displayed by the display component.

[0114] Confirming that the guide cover 314 is in contact with the guide column confirms that the latch 33 is in the center of the guide ring. The remote control assembly 40 drives the first electric push rod 321 and the second electric push rod 322, which drive the latch 33 to perform a perforation movement. When the latch 33 moves to the set position, the latch sensor turns on and provides a signal feedback to remind the operator to stop the operation. The process of the latch 33 inserting or withdrawing from the guide ring can also be observed by imaging through the camera 341. After the latch 33 and the guide ring are installed in place, the guide column is slowly lifted to the moving height by a crane, and then moved to the preset installation position; The remote operation control component 40 drives the first electric push rod 321 and the second electric push rod 322 to retract the pin 33 to its original position, and the pin sensor turns on and provides signal feedback; and after observing through imaging that the pin 33 is completely separated from the guide ring, the vehicle can be controlled to remove the guide column disassembly and assembly tool 100; finally, press the power switch to ensure that all indicator lights are off, and the guide column disassembly and assembly tool 100 is now shut down.

[0115] The guide post disassembly and assembly tool 100 of the embodiment of the present application is quick to install and easy to operate, which reduces maintenance costs, improves maintenance efficiency, shortens operation time, and reduces the radiation dose to operators.
