Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0044] In the description of the present application, “plurality” means at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.

[0045] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0046] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0047] In the description of the present application, it should be understood that the terms "inside", "outside", "side", "top", "bottom", "front", "back", etc., indicating directions or positional relationships, are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present application.

[0048] In the description of this application, it should be noted that the term "and / or" is merely a description of the association relationship between associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0049] It should also be noted that, in the embodiments of the present application, the same figure mark is used to represent 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.

[0050] Nuclear power plants usually need to be overhauled regularly to ensure their safe operation; during the overhaul, the heat transfer tubes and other components in the evaporator usually need to be inspected and repaired; the shell of the evaporator usually has an inlet and outlet, which are closed by flange covers; during the in-service inspection of the heat transfer tubes inside the evaporator, the flange covers need to be removed to facilitate personnel or equipment to enter the interior of the evaporator through the inlet and outlet for inspection. After the inspection is completed, the flange covers need to be reset to close the inlet and outlet.

[0051] However, in the actual maintenance process, first remove some of the bolts fixing the flange cover, fix the rope of the winch tool in the bolt hole where the shell and the bolts are connected, then clamp the winch tool on the flange cover, and then remove the remaining bolts fixing the flange cover, start the winch tool to place the cover in a horizontal position. At this time, the winch tool is located below the flange, and the rope is passed through the first bolt hole of the flange cover. The rope is then lowered to the designated position, and the winch tool is removed, thus completing the removal of the flange cover. However, in this way, the rope is severely worn due to long-term contact with the flange cover, and there is a risk of the flange cover falling off, which poses a great safety hazard. Secondly, both installation and disassembly require installation and disassembly of the winch tool, which is cumbersome and time-consuming.

[0052] Based on this, an embodiment of the present application provides a flange cover disassembly and assembly device for removing the flange cover on an evaporator or other equipment. The flange cover can be a cover covering any through hole on the shell of the equipment, such as a manhole, etc. The flange cover disassembly and assembly device can quickly install and remove the flange cover, and the disassembly is highly safe.

[0053] The following combination Figures 1 to 17 The flange cover plate disassembly and assembly device 100 according to an embodiment of the present application is illustrated.

[0054] See also Figures 1 to 4As shown, in some embodiments, the flange cover disassembly and assembly equipment 100 includes a base 10, a first lifting mechanism 20 and a cover positioning mechanism 40; the cover positioning mechanism 40 includes a connected positioning member 41 and a support unit 42, the support unit 42 has a support surface 4201 for supporting the flange cover 210, and the positioning member 41 is used to connect with the flange cover 210 to limit the movement of the flange cover 210 on the support surface 4201; the first lifting mechanism 20 includes a lifting connection member 21, a lifting drive member 22 and a horizontal sliding unit 23, the lifting drive member 22 is installed on the lifting connection member 21, the lifting drive member 22 is connected to the support unit 42, and the lifting drive member 22 is used to drive the support unit 42 to rise and fall; the lifting connection member 21 is slidably connected to the base 10 through the horizontal sliding unit 23, so that in the process of connecting the positioning member 41 with the flange cover 210, the lifting connection member 21 can slide along the lifting direction perpendicular to the lifting drive member 22 relative to the base 10 with the positioning member 41.

[0055] The base 10 may refer to a mounting base for the first lifting mechanism 20 and the cover plate positioning mechanism 40 , and plays a role in supporting and fixing components. The base 10 may be formed by splicing rods or plates.

[0056] The cover plate positioning mechanism 40 may refer to a component used to support and fix the flange cover plate 210; the cover plate positioning mechanism 40 includes a positioning member 41 and a support unit 42, the support unit 42 has a support surface 4201, the support surface 4201 is used to receive the flange cover plate 210, and plays a role in supporting the flange cover plate 210 to facilitate the disassembly and assembly of the flange cover plate 210; the positioning member 41 may refer to a component used to fix the flange cover plate 210, in the process of the flange cover plate 210 moving to the support surface 4201, the positioning member 41 is connected to the flange cover plate 210, and finally the flange cover plate 210 is fixed on the support surface 4201, so that the flange cover plate 210 will not fall from the support surface 4201, thereby reducing the risk of the flange cover plate 210 falling, reducing the safety hazards of the disassembly of the flange cover plate 210, and improving the safety of disassembly.

[0057] The positioning member 41 and the flange cover plate 210 can be connected by means of snap-fitting or plug-in.

[0058] The first lifting mechanism 20 may refer to a component for driving the cover plate positioning mechanism 40 to rise and fall. The first lifting mechanism 20 drives the cover plate positioning mechanism 40 to rise, so that the cover plate positioning mechanism 40 can be moved to the flange cover plate 210 located at a high position to facilitate the subsequent loading of the flange cover plate 210.

[0059] The first lifting mechanism 20 includes a lifting connection member 21, a lifting drive member 22 and a horizontal sliding unit 23. The lifting connection member 21 may refer to a mounting base of the lifting drive member 22, which supports the lifting drive member 22. The lifting drive member 22 is used to drive the cover plate positioning mechanism 40 to lift. The lifting drive member 22 may be a cylinder, a linear module or other components.

[0060] The horizontal sliding unit 23 can realize the sliding connection between the lifting connection member 21 and the base 10. The lifting connection member 21 can slide relative to the base 10 along the lifting direction perpendicular to the lifting drive member 22. The lifting connection member 21 is connected to the lifting drive member 22, and the lifting drive member 22 is connected to the support unit 42. The positioning member 41 is connected to the support unit 42. The lifting connection member 21 can slide relative to the base 10, and the support unit 42 and the positioning member 41 can also slide relative to the base 10. Then the positioning member 41 and the flange cover plate 210 appear In the case of deviation, during the connection between the positioning member 41 and the flange cover plate 210, the flange cover plate 210 will apply a force to the positioning member 41. Under this force, the positioning member 41 can move relative to the base 10 to adapt to the flange cover plate 210, so that the positioning member 41 can be accurately connected to the flange cover plate 210. This method does not require manual adjustment of the positioning member 41. The positioning member 41 can move with the flange cover plate 210, which simplifies the connection operation between the positioning member 41 and the flange cover plate 210 and improves the disassembly and assembly efficiency of the flange cover plate 210.

[0061] When the flange cover 210 needs to be removed from the shell 220, the flange cover disassembly and assembly equipment 100 is moved to the bottom of the flange cover 210, and then the first lifting mechanism 20 is started, and the lifting drive member 22 drives the support unit 42 and the positioning member 41 to rise. During the process of the support surface 4201 moving to the flange cover 210, the positioning member 41 is connected to the flange cover 210 until the flange cover 210 abuts against the support surface 4201, and then the flange cover 210 is removed from the shell 220. At this time, the flange cover 210 can stably abut against the support surface 4201 under the action of its own gravity, and the positioning member 41 can fix the flange cover 210 on the support surface 4201. Finally, the first lifting mechanism 20 is started to move downward, so that the flange cover 210 moves downward and waits to be moved to a preset position for storage; the disassembly of the flange cover 210 is completed in this way.

[0062] When the flange cover 210 needs to be installed on the shell 220, the flange cover 210 is installed on the support surface 4201, and the positioning member 41 fixes the flange cover 210. Then, the first lifting mechanism 20 is started, and the lifting drive member 22 drives the cover positioning mechanism 40 and the flange cover 210 connected thereto to rise. After the flange cover 210 moves to the required installation position, the flange cover 210 is fixed on the shell 220. In this way, the installation of the flange cover 210 is completed.

[0063] The flange cover plate disassembly and assembly equipment 100 of the embodiment of the present application utilizes the cooperation between the first lifting mechanism 20 and the cover plate positioning mechanism 40 to complete the disassembly and assembly of the flange cover plate 210; during the disassembly and assembly process, the lifting drive member 22 is used to drive the support unit 42 to rise until it moves to the flange cover plate 210, and then, while the support surface 4201 of the support unit 42 is used to support the flange cover plate 210, the flange cover plate 210 is also fixed by the positioning member 41 of the cover plate positioning mechanism 40, so that the flange cover plate 210 can be stably supported and fixed during the disassembly and assembly process, reducing the risk of the flange cover plate 210 falling, improving the safety of the disassembly and assembly of the flange cover plate 210, and the disassembly and assembly operation is simple, which can improve the disassembly and assembly efficiency of the flange cover plate 210; in addition, since the lifting connection member 21 and the base 10 are connected horizontally The sliding unit 23 is connected so that the positioning member 41 can also slide relative to the base 10. Then, when the lifting drive member 22 drives the positioning member 41 to move and connect with the flange cover 210, if the flange cover 210 and the positioning member 41 are misaligned, during the process of the flange cover 210 and the positioning member 41 contacting and connecting with each other, the interaction between the flange cover 210 and the positioning member 41 and the generated interaction force can drive the positioning member 41 to move relative to the base 10, thereby driving the positioning member 41 to accurately connect with the flange cover 210. This method does not require manual adjustment of the positioning member 41, and the positioning member 41 can be adapted and moved according to the position of the flange cover 210, thereby simplifying the connection operation between the positioning member 41 and the flange cover 210 and improving the disassembly and assembly efficiency of the flange cover 210.

[0064] Compared with the disassembly operation process using a winch tool, the flange cover disassembly and assembly equipment 100 of the embodiment of the present application can significantly improve work efficiency and reduce labor input; in addition, the flange cover 210 has a high disassembly and assembly efficiency, which can shorten the operation time and reduce the radiation dose of the operators, and can also avoid the industrial safety risk of the flange cover 210 falling off due to long-term contact and wear between the rope and the flange cover 210.

[0065] See also Figure 5 and Figure 6 As shown, in some embodiments, the horizontal sliding unit 23 includes a first linear sliding member 231, a second linear sliding member 232 and a sliding connection member 233, and the sliding connection member 233 is slidingly connected to the base 10 through the first linear sliding member 231, so that the sliding connection member 233 can slide along the first direction relative to the base 10; the lifting connection member 21 is slidingly connected to the sliding connection member 233 through the second linear sliding member 232, so that the lifting connection member 21 can slide along the second direction relative to the sliding connection member 233; the first direction and the second direction intersect, and the first direction and the second direction are perpendicular to the lifting direction of the lifting drive 22.

[0066] The sliding connection 233 is used to connect the first linear sliding member 231 and the second linear sliding member 232. During the connection process between the positioning member 41 and the flange cover 210, the following movement of the positioning member 41 in the first direction can be achieved through the first linear sliding member 231, and the following movement of the positioning member 41 in the second direction can be achieved through the second linear sliding member 232. In this way, the positioning member 41 has following movement in two directions, and the following range of the positioning member 41 is wide, which can meet the needs of more scenarios, effectively simplifying the connection operation between the positioning member 41 and the flange cover 210, and improving the disassembly and assembly efficiency of the flange cover 210.

[0067] In some examples, the first direction and the second direction may form an angle, which may be an acute angle or a right angle.

[0068] For example, the first direction may be perpendicular to the second direction. Figures 11 to 13 The middle X direction, the second direction can be found in Figures 11 to 13 In the Y direction, the lifting direction of the first lifting mechanism 20 can be referred to Figures 11 to 13 Middle Z direction.

[0069] In some embodiments, the first linear slide 231 includes a first slide rail 2311 and a first slider 2312.

The first slider 2312 slides along the first slide rail 2311, thereby realizing the follow-up movement of the positioning member 41 along the first direction; the first linear slide 231 adopts the above structure, the reaction force of the follow-up movement of the positioning member 41 is small, the smoothness is good, and the structure is simple and the processing and manufacturing are convenient.

[0070] In some embodiments, the number of the first linear slide members 231 is one or more, and the plurality of first linear slide members 231 are arranged at intervals along the second direction, so that the movement of the positioning member 41 along the first direction is more stable, thereby improving the stability of the movement of the positioning member 41. For example, the number of the first linear slide members 231 is two, and the two first linear slide members 231 are located on opposite sides of the sliding connector 233.

[0072] During the storage of the flange cover 210 , the first locking mechanism 234 can be used to relatively fix the base 10 and the lifting connection member 21 along the first direction, thereby reducing the movement risk of the flange cover 210 and improving the storage reliability of the flange cover 210 .

[0073] By rotating the first double-headed screw 2342, the two first clamping blocks 2343 are relatively close to each other, thereby clamping the first slide rail 2311, and locking the sliding connection member 233 and the first slide rail 2311; by rotating the first double-headed screw 2342 in the opposite direction, the first slide rail 2311 can be loosened, and unlocking the sliding connection member 233 and the first slide rail 2311 can be achieved.

[0077] In some embodiments, the number of the second linear slide members 232 is one or more, and the plurality of second linear slide members 232 are arranged at intervals along the first direction, so that the movement of the positioning member 41 along the second direction is more stable, thereby improving the stability of the movement of the positioning member 41. For example, the number of the second linear slide members 232 is two, and the two second linear slide members 232 are located on opposite sides of the sliding connector 233.

[0078] See also Figure 7 As shown, in some embodiments, the first lifting mechanism 20 also includes a second locking mechanism 235 for locking the second slide rail 2321 and the lifting connection member 21; the second locking mechanism 235 includes a second fixed block 2351, a second double-headed screw 2352 and two second clamping blocks 2353, the second fixed block 2351 is installed on the lifting connection member 21, the second double-headed screw 2352 is rotatably installed on the second fixed block 2351, the two second clamping blocks 2353 are respectively screwed to the two side parts of the second double-headed screw 2352, and the two second clamping blocks 2353 are located on both sides of the second slide rail 2321 along the second direction.

[0080] By rotating the second double-headed screw 2352, the two second clamping blocks 2353 are relatively close to each other, thereby clamping the second slide rail 2321, and locking the lifting connection member 21 and the second slide rail 2321; by rotating the second double-headed screw 2352 in the opposite direction, the second slide rail 2321 can be loosened, and unlocking the lifting connection member 21 and the second slide rail 2321 can be achieved. The second locking mechanism 235 adopts the above structure, which has a simple structure and is easy to manufacture.

[0081] Of course, in other examples, the second locking mechanism 235 may also be other structures.

[0082] It should be noted that the second locking mechanism 235 has the same structure as the first locking mechanism 234. Figure 7 The second locking mechanism 235 and the first locking mechanism 234 are illustrated as an example.

[0083] In some examples, the structure of the first locking mechanism 234 may also be different from the structure of the second locking mechanism 235 , which can be determined based on actual conditions.

[0084] In some embodiments, a second rotating wheel 2354 is provided at the end of the second double-headed screw 2352 to facilitate the rotation of the second double-headed screw 2352 .

[0085] See also Figure 1 , Figure 8 and Fig. 9 As shown, in some embodiments, the positioning member 41 includes a plurality of positioning columns 411 , which are used to be inserted into the first bolt holes 211 of the flange cover plate 210 , and the plurality of positioning columns 411 are installed on the support surface 4201 and are arranged at intervals along the circumference of the support surface 4201 .

[0086] The flange cover plate 210 and the housing 220 are fixed by bolts, and the bolts pass through the first bolt holes 211 of the flange cover plate 210 and the second bolt holes 2201 of the housing 220, so as to fix the flange cover plate 210 and the housing 220.

[0087] The positioning column 411 may refer to a component used to be inserted into the first bolt hole 211 of the flange cover plate 210; during the disassembly process of the flange cover plate 210, the mobile drive unit 43 may drive multiple positioning columns 411 to be inserted into multiple first bolt holes 211 of the flange cover plate 210, so that after the flange cover plate 210 is separated from the shell 220, the flange cover plate 210 can still be stably fixed on the support surface 4201; and, the operation of inserting the positioning column 411 into the first bolt hole 211 can be adapted to the movement of the mobile drive unit 43, and the fixing operation of the flange cover plate 210 on the support surface 4201 is simpler and more efficient.

[0088] The flange cover plate 210 has multiple first bolt holes 211, which are distributed along the circumference of the flange cover plate 210. Multiple positioning columns 411 are distributed at intervals along the circumference of the support surface 4201, so that the multiple positioning columns 411 can be respectively inserted into the multiple bolt holes of the flange cover plate 210, which can reduce the risk of the flange cover plate 210 moving on the support surface 4201, and the fixation of the flange cover plate 210 is more stable and reliable; for example, the number of positioning columns 411 is four.

[0089] See also Figure 1 , Figure 8 and Fig. 9 As shown, in some embodiments, the end of the positioning column 411 facing away from the support surface 4201 is a tapered structure, and the large end of the tapered structure is arranged away from the support surface 4201 .

[0090] The shape of the positioning column 411 is compatible with the shape of the first bolt hole 211 to better fix the flange cover 210; the diameter of the end of the positioning column 411 facing away from the support surface 4201 is smaller than the end of the positioning column 411 close to the support surface 4201. For example, the end of the positioning column 411 facing away from the support surface 4201 is a tapered structure, and the closer to the support surface 4201, the larger the diameter. The tapered structure of the positioning column 411 can facilitate the small diameter of the end of the positioning column 411 facing away from the support surface 4201, and the positioning column 411 can be offset to a certain extent. The first bolt hole 211 is inserted into the differential range, and as the positioning column 411 continues to be inserted, the outer peripheral surface of the tapered structure interacts with the hole wall surface of the first bolt hole 211, and the first bolt hole 211 exerts a certain force on the positioning column 411. The setting of the horizontal sliding unit 23 allows the positioning column 411 to move under the force, so that the positioning column 411 can be smoothly inserted into the positioning column 411, which simplifies the connection operation between the positioning member 41 and the flange cover plate 210 and improves the disassembly and assembly efficiency of the flange cover plate 210.

[0091] See also Figure 1 , Figure 8 and Fig. 9 As shown, in some embodiments, the positioning member 41 further includes a blocking block 412 , which is detachably mounted on the end of the positioning column 411 facing away from the support surface 4201 , and is used to prevent the flange cover 210 from being separated from the positioning column 411 .

[0092] After the flange cover 210 is removed from the shell 220, the blocking block 412 is installed at the end of the positioning column 411 facing away from the support surface 4201. The diameter of the blocking block 412 is larger than the aperture of the first bolt hole 211, so that the flange cover 210 will not fall off the positioning column 411. The flange cover 210 can be stably fixed on the positioning column 411, reducing the risk of the flange cover 210 falling and facilitating the subsequent vertical storage of the flange cover 210.

[0093] The number of blocking blocks 412 can be the same as the number of positioning columns 411, and the blocking blocks 412 and the positioning columns 411 are set in a one-to-one correspondence. Of course, the number of blocking blocks 412 can also be less than the number of positioning columns 411, and the blocking blocks 412 and the positioning columns 411 can be connected by bolts, screws and other components.

[0094] See also Figure 1 As shown, in some embodiments, the flange cover plate disassembly and assembly equipment 100 also includes a guide member 50, which is used to pass through the first bolt hole 211 of the flange cover plate 210 and to be fixedly connected to the second bolt hole 2201 of the shell 220; the support surface 4201 is provided with an avoidance hole 4211 for avoiding the guide member 50.

[0095] When the flange cover plate 210 is disassembled, some of the bolts are removed, and the guide member 50 is inserted from the first bolt hole 211 of the flange cover plate 210 into the second bolt hole 2201 of the housing 220 and fixed to the housing 220. The mobile drive unit 43 drives the support surface 4201 to fit on the flange cover plate 210, and then the remaining bolts are removed. Finally, the mobile drive unit 43 drives the flange cover plate 210 to move away from the housing 220. At this time, the flange cover plate 210 moves along the guide member 50 under its own gravity. The guide member 50 can guide the flange cover plate 210, reduce the risk of the flange cover plate 210 falling, and improve the safety of the flange cover plate 210 disassembly.

[0096] When installing the flange cover 210, first install the guide member 50 in the second bolt hole 2201 of the shell 220, then the mobile drive unit 43 can drive the flange cover 210 to move accurately to the installation position of the shell 220 along the guide member 50, and finally, remove the guide member 50 and install the bolts.

[0097] The support surface 4201 is provided with an avoidance hole 4211 for avoiding the guide member 50; during the process of disassembling the flange cover plate 210, the guide member 50 can be inserted into the avoidance hole 4211 to avoid the guide member 50. After the guide member 50 is inserted into the avoidance hole 4211, as the support surface 4201 continues to rise, the outer peripheral surface of the guide member 50 interacts with the hole wall of the avoidance hole 4211, thereby driving the positioning member 41 and the support unit 42 to move, so that the positioning member 41 and the flange cover plate 210 can be preliminarily aligned to facilitate the subsequent connection of the positioning member 41 and the flange cover plate 210.

[0098] The guide member 50 is a columnar structure, and the shape of the guide member 50 matches the shape of the threaded hole to better guide the flange cover 210. The guide member 50 can be a guide bolt 51, a guide column, or other structures.

[0099] By adopting the technical solution of this embodiment, the guide member 50 can guide the movement of the flange cover plate 210, so that the disassembly and assembly of the flange cover plate 210 is more accurate, safe and efficient.

[0100] See also Figures 8 to 12 As shown, in some embodiments, the cover positioning mechanism 40 also includes a mobile drive unit 43, which is connected to the support unit 42, and the mobile drive unit 43 is connected to the lifting drive member 22; the mobile drive unit 43 is used to drive the support unit 42 to move in a direction perpendicular to the support surface 4201.

[0101] The mobile driving unit 43 may refer to a component used to drive the support unit 42 to move. The mobile driving unit 43 drives the support unit 42 to move in a direction perpendicular to the support surface 4201; the mobile driving unit 43 may be, but is not limited to, a cylinder, a linear module and other components.

[0102] During the removal process of the flange cover plate 210, when the support surface 4201 moves to the flange cover plate 210, the mobile drive unit 43 drives the support unit 42 to move in a direction perpendicular to the support surface 4201, so that the support surface 4201 can move close to the flange cover plate 210 until the support surface 4201 can be close to the flange cover plate 210. Thereafter, after the flange cover plate 210 is removed from the shell 220, the flange cover plate 210 can be stably fixed on the support surface 4201, thereby improving the safety of the removal of the flange cover plate 210; thereafter, the mobile drive unit 43 drives the flange cover plate 210 away from the shell 220. At this time, the mobile drive unit 43 moves along the axial direction of the flange cover plate 210, which can reduce the risk of interference between the flange cover plate 210 and other components, improve the safety of the removal of the flange cover plate 210, and also facilitate the subsequent first lifting mechanism 20 to drive the flange cover plate 210 to move downward.

[0103] During the installation of the flange cover plate 210 , the mobile driving unit 43 can drive the flange cover plate 210 to directly abut against the installation position of the shell 220 , thereby supporting the flange cover plate 210 and facilitating the installation of the flange cover plate 210 .

[0104] By adopting the technical solution of this embodiment and the setting of the mobile driving unit 43, during the disassembly and assembly of the flange cover plate 210, the support surface 4201 can always be in contact with the flange cover plate 210, which is beneficial to improving the safety of the disassembly and assembly of the flange cover plate 210. In addition, during the operation, the mobile driving unit 43 has space to move toward the flange cover plate 210, and the space can also provide a secondary adjustment space for the first lifting mechanism 20, so that the first lifting mechanism 20 can first drive the support unit 42 to move to the approximate position and then perform a secondary adjustment, which makes the disassembly and assembly operation of the flange cover plate 210 simpler and improves the disassembly and assembly efficiency of the flange cover plate 210.

[0105] In some embodiments, the mobile drive unit 43 also includes a first screw rod 431, a first nut 432 and a first connecting member 433. The first connecting member 433 is connected to the lifting drive member 22, and the first nut 432 is threadedly connected to the first screw rod 431; the first screw rod 431 is rotatably installed on the support unit 42 and is perpendicular to the support surface 4201, and the first nut 432 is connected to the first connecting member 433.

[0106] The first connecting member 433 may refer to the mounting base of the first nut 432, which plays the role of supporting the first nut 432. The first connecting member 433 may be a plate or a connecting frame structure. The first connecting member 433 serves as a connecting component connecting the lifting drive member 22 and the first nut 432. The first nut 432 is connected to the first connecting member 433. The first nut 432 may pass through the first connecting member 433 and be fixedly connected to the first connecting member 433. The first nut 432 and the first connecting member 433 may be connected by bolts, screws, etc. The first connecting member 433 is connected to the lifting drive member 22. The lifting drive member 22 drives the first connecting member 433 to rise and fall. The first connecting member 433 drives the first screw rod 431, the first nut 432 and the support unit 42 connected thereto to rise and fall, thereby realizing the lifting and lowering adjustment of the support surface 4201.

[0107] The first nut 432 is sleeved outside the first screw rod 431, and the external thread of the first screw rod 431 is meshed with the internal thread of the first nut 432. The first screw rod 431 is rotatably mounted on the support unit 42, so that the first screw rod 431 can rotate around its own axis.

[0108] During the rotation of the first screw rod 431, the first nut 432 moves along the axial direction of the first screw rod 431 relative to the first screw rod 431, and the first connecting member 433 is connected to the lifting drive member 22, so that the first nut 432 is fixed relative to the lifting drive member 22, and the first screw rod 431 moves and drives the support unit 42 to move, and the first screw rod 431 is perpendicular to the support surface 4201, so that during the disassembly process of the flange cover plate 210, the first screw rod 431 can drive the support surface 4201 to approach or move away from the flange cover plate 210.

[0109] By adopting the technical solution of this embodiment, the first screw rod 431 and the first nut 432 cooperate with each other to accurately adjust the moving distance of the support surface 4201, which is beneficial to improving the safety and efficiency of the disassembly and assembly of the flange cover plate 210; in addition, the first nut 432 is fixed and the first screw rod 431 is moved, which can save space and improve the structural compactness of the flange cover plate disassembly and assembly equipment 100.

[0110] In some examples, the first screw rod 431 and the first nut 432 may adopt a trapezoidal screw structure to more accurately adjust the moving distance of the support surface 4201. Of course, in other examples, other structures may also be adopted.

[0111] In some embodiments, the support unit 42 includes a support plate 421 and a second connecting member 422, the second connecting member 422 is connected to the mobile drive unit 43, the support plate 421 has a support surface 4201, and the second connecting member 422 is located on the side of the support plate 421 facing away from the support surface 4201; the second connecting member 422 is rotatably connected to the support plate 421 so that the support plate 421 can rotate relative to the second connecting member 422 around the central axis of the arrangement of multiple positioning columns 411.

[0112] The support plate 421 may refer to a plate member for contacting with the flange cover plate 210 and for supporting the flange cover plate 210; the second connecting member 422 is used to connect the mobile driving unit 43 and the support plate 421, and the mobile driving unit 43 drives the second connecting member 422 to move, thereby driving the support plate 421 to move. The surface of the support plate 421 facing away from the second connecting member 422 forms a support surface 4201.

[0113] The multiple first bolt holes 211 of the flange cover plate 210 are arranged at intervals around the axis of the flange cover plate 210; the multiple positioning columns 411 cooperate with the multiple first bolt holes 211, then when the flange cover plate 210 is tightly against the support surface 4201, the multiple positioning columns 411 are also arranged at intervals around the axis of the flange cover plate 210, so that the central axis of the arrangement of the multiple positioning columns 411 can refer to the axis when the flange cover plate 210 is tightly against the support surface 4201.

[0114] The second connecting member 422 is rotatably connected to the support plate 421, so that the support plate 421 and the second connecting member 422 can rotate relative to each other, and the support plate 421 can rotate around the central axis of the arrangement of the plurality of positioning members 41. The rotation of the support plate 421 drives the positioning column 411 to rotate. When the positioning column 411 is misaligned with the corresponding first bolt hole 211, the support plate 421 can be rotated to adjust the position of the positioning column 411 so that the positioning column 411 can be accurately inserted into the corresponding first bolt hole 211. The adjustment of the position of the positioning column 411 can also meet the different requirements for the disassembly and assembly of the flange cover plate 210.

[0115] In some embodiments, the second connecting member 422 also includes a first connecting plate 4221 and a rotating plate 4222, the rotating plate 4222 is rotatably connected to the mobile drive unit 43, and the first connecting plate 4221 is located between the rotating plate 4222 and the support plate 421; the first connecting plate 4221 is provided with a first through hole 42211, and the surface of the rotating plate 4222 facing the first connecting plate 4221 is provided with a protrusion 42221, the protrusion 42221 is rotatably penetrated into the first through hole 42211, and the protrusion 42221 is fixedly connected to the rotating plate 4222.

[0116] The rotating plate 4222 may refer to a plate that can rotate relative to the first connecting plate 4221. The first connecting plate 4221 supports the support plate 421 and the first connecting plate 4221. The rotating plate 4222 is rotatably connected to the mobile driving unit 43. The mobile driving unit 43 drives the rotating plate 4222 to move. The rotating plate 4222 drives the first connecting plate 4221 and the support plate 421 to move, so that the support surface 4201 can be close to the flange cover plate 210.

[0117] The first connecting plate 4221 is provided with a first through hole 42211, and the first through hole 42211 penetrates the first connecting plate 4221 along the plate thickness direction of the first connecting plate 4221; the rotating plate 4222 is provided with a protrusion 42221, and the protrusion 42221 extends into the first through hole 42211. The rotating plate 4222 can rotate relative to the mobile driving unit 43, and the rotating plate 4222 is fixed to the supporting plate 421, so that the rotation of the supporting plate 421 can be realized by the rotation of the protrusion 42221 in the first through hole 42211, and then the position of the positioning column 411 can be adjusted.

[0118] In some examples, the protrusion 42221 and the first through hole 42211 may be clearance-fitted.

[0119] In some examples, the protrusion 42221 and the support plate 421 may be connected by means of studs, screws, clamping, bonding, or the like.

[0120] In some examples, a flange 42222 is provided on the peripheral side of the rotating plate 4222 , and the first connecting plate 4221 is clamped between the supporting plate 421 and the flange 42222 at the edge of the first through hole 42211 , so that the protrusion 42221 will not fall out of the first through hole 42211 .

[0121] In some examples, the end of the first screw rod 431 can be rotatably connected to the rotating plate 4222 through components such as bearings. This arrangement has a compact structure and is easy to process and manufacture.

[0122] By adopting the technical solution of this embodiment, the first connecting plate 4221 and the rotating plate 4222 are rotatably connected by using the structure of the first through hole 42211 and the protrusion 42221. The structure is simple and compact, which is conducive to reducing the external dimensions of the flange cover disassembly and assembly equipment 100.

[0123] In some embodiments, the second connecting member 422 also includes a second connecting plate 4223 and a first guide rod 4224. The first connecting plate 4221 and the second connecting plate 4223 are arranged at intervals along the axial direction of the first screw rod 431. The first guide rod 4224 is connected between the first connecting plate 4221 and the second connecting plate 4223. One end of the first screw rod 431 is rotatably connected to the rotating plate 4222 by bearings and other components, and the other end is rotatably connected to the second connecting plate 4223 by bearings and other components. The first connecting member 433 is located between the first connecting plate 4221 and the second connecting plate 4223. The first connecting plate 4221 is provided with a first guide sleeve 435. The first guide sleeve 435 is sleeved on the first guide rod 4224. The first screw rod 431 passes through the first connecting member 433.

[0124] During the movement of the first screw rod 431, the first guide rod 4224 slides in the first guide sleeve 435, thereby guiding the movement of the second connecting member 422 and the support plate 421, making the movement of the second connecting member 422 and the support plate 421 more stable and reliable; in addition, the first connecting member 433 is located between the first connecting plate 4221 and the second connecting plate 4223, and its structure is compact and can save space. The second connecting member 422 adopts the structure of the first connecting plate 4221, the second connecting plate 4223 and the guide rod, and its structural strength is good, which is conducive to meeting the disassembly requirements of the flange cover plate 210 with a large mass, and also improves the reliability of the flange cover plate disassembly and assembly equipment 100.

[0125] In some embodiments, there are multiple guide rods, which are arranged in a ring around the axis of the first screw rod 431, which is beneficial to improving the structural strength of the second connecting member 422. By way of example, there are four guide rods.

[0127] In some embodiments, a first rotating nut 434 is fixed to one end of the first screw rod 431 facing away from the support plate 421, and the first rotating nut 434 is used to cooperate with a wrench, and the user can use the wrench to clamp the first rotating nut 434 to rotate the first screw rod 431. The wrench can be a pneumatic wrench, a hydraulic wrench, etc.

[0128] In some embodiments, a hand wheel is fixed to one end of the first screw rod 431 facing away from the support plate 421 to facilitate the rotation of the first screw rod 431 .

[0129] In some embodiments, the support unit 42 further includes a locking member 4225 , and the locking member 4225 is used to lock the support plate 421 and the second connecting member 422 when the support plate 421 rotates to a preset position relative to the second connecting member 422 .

[0130] The support plate 421 rotates to a preset position relative to the second connecting member 422, which may refer to a position when the positioning column 411 can be arranged relative to the corresponding first bolt hole 211. After the support plate 421 moves to the preset position, the support plate 421 and the second connecting member 422 can be relatively locked by the locking member 4225 to achieve the fixation of the support plate 421 and the second connecting member 422, so that the positioning column 411 can be accurately inserted into the corresponding first bolt hole 211; in addition, the support plate 421 is fixed relative to the second connecting member 422, which is also beneficial to improve the fixing stability of the flange cover plate 210 on the support surface 4201, and is beneficial to improve the safety of disassembly and assembly of the flange cover plate 210.

[0131] In some examples, locking member 4225 may be a locking pin or the like.

[0132] In some embodiments, the locking member 4225 includes a locking plate 42251 and a locking bolt 42252. The locking plate 42251 is installed on the side of the second connecting member 422. The locking plate 42251 is provided with a connecting hole 42253. The locking bolt 42252 is screwed into the connecting hole 42253. The end of the locking bolt 42252 can be abutted against the side of the support plate 421 to lock the support plate 421 and the second connecting member 422.

[0133] The locking plate 42251 serves as a mounting base for the locking bolt 42252 and plays a role in supporting the locking bolt 42252 . For example, the locking plate 42251 may be fixed to a side portion of the first connecting plate 4221 .

[0134] The locking plate 42251 is provided with a connecting hole 42253, and the locking bolt 42252 is passed through the connecting hole 42253. The outer thread of the locking bolt 42252 is meshed with the inner thread of the connecting hole 42253. By rotating the locking bolt 42252, the locking bolt 42252 moves toward the supporting plate 421, so that the end of the locking bolt 42252 can be against the side of the supporting plate 421, thereby realizing the relative fixation of the second connecting member 422 and the supporting plate 421, that is, the locking of the second connecting member 422 and the supporting plate 421 is realized; loosening the locking bolt 42252, so that the end of the locking bolt 42252 is separated from the side of the supporting plate 421, at this time, the supporting plate 421 can rotate relative to the second connecting member 422, so as to realize the adjustment of the position of the positioning column 411.

[0135] The number of locking members 4225 is one or more, and the multiple locking members 4225 are distributed along the circumference of the second connecting member 422 to better lock the support plate 421. For example, the number of locking members 4225 is two, and the two locking members 4225 are located on opposite sides of the first connecting plate 4221.

[0136] By adopting the technical solution of this embodiment, the locking and fixing of the second support plate 421 is achieved by utilizing the cooperation between the locking plate 42251 and the locking bolt 42252 , which has a simple structure and is easy to operate.

[0137] See also Figure 2 , Fig.13 and Fig.14 As shown, in some embodiments, the flange cover disassembly and assembly equipment 100 also includes an angle adjustment mechanism 30, which is connected between the support unit 42 and the lifting drive member 22, and the angle adjustment mechanism 30 is used to drive the support unit 42 to flip to adjust the inclination angle α of the support surface 4201.

[0138] The angle adjustment mechanism 30 may refer to a mechanism for adjusting the angle of the cover positioning mechanism 40. The angle adjustment mechanism 30 drives the support unit 42 to flip. When the support unit 42 flips, the angle between the support surface 4201 and the horizontal plane changes, that is, the inclination angle α of the support surface 4201 changes, so that the support surface 4201 of the support unit 42 can be parallel to the inclined flange cover 210, and the support unit 42 can stably and reliably support the flange cover 210, thereby improving the stability and safety of the disassembly of the flange cover 210.

[0139] During the storage process of the flange cover, after it is moved to the preset position, the angle adjustment mechanism 30 is adjusted so that the support surface 4201 is vertical and the flange cover 210 is vertically arranged to reduce the storage space of the flange cover 210; of course, in other examples, the flange cover 210 can also be stored at other angles, for example: horizontal state or the flange cover 210 is 30°, 45°, etc. to the horizontal plane.

[0140] By adopting the technical solution of this embodiment, the flange cover plate disassembly and assembly device 100 can disassemble and assemble the flange cover plate that is set obliquely, which can improve the universal scope of the flange cover plate disassembly and assembly device 100.

[0145] The second screw rod 321, the second nut 322, the connecting rod 323 and the support unit 42 form a four-bar mechanism. The second screw rod 321 is rotated to make the second nut 322 move along the length direction of the second screw rod 321, thereby driving the connecting rod 323 to swing, and then driving the support unit 42 connected thereto to flip.

[0146] The second screw rod 321 can be rotatably mounted on the third connecting member 31 through components such as bearings. The third connecting member 31 is a plate or a connecting frame structure.

[0147] For example, the connecting rod 323 is connected to the first connecting member 433 , and the connecting rod 323 swings, driving the first connecting member 433 to swing, thereby driving the supporting unit 42 to flip, thereby achieving adjustment of the inclination angle α of the supporting surface 4201 .

[0148] By adopting the technical solution of this embodiment, the angle adjustment drive unit 32 adopts the second screw rod 321, the second nut 322 and the connecting rod 323, which can accurately adjust the inclination angle α of the support surface 4201, which is beneficial to improving the disassembly and assembly efficiency of the flange cover 210; in addition, the angle adjustment drive unit 32 adopts a four-bar mechanism to stop the rotation of the second screw rod 321, the position of the connecting rod 323 is fixed, and the position of the support unit 42 is also fixed accordingly, which is equivalent to achieving the locking and fixation of the support unit 42, reducing the risk of the flange cover 210 falling due to the random flipping of the support unit 42, and improving the safety of the disassembly and assembly of the flange cover 210.

[0149] In some embodiments, a second rotating nut 324 is fixed to one end of the second screw rod 321, and the second rotating nut 324 is used to cooperate with a wrench. The user can use the wrench to clamp the second rotating nut 324 to rotate the second screw rod 321. The wrench can be a pneumatic wrench, a hydraulic wrench, etc.

[0150] In some embodiments, a hand wheel is fixed to one end of the second screw rod 321 facing away from the support plate 421 to facilitate the rotation of the second screw rod 321 .

[0152] In some examples, the number of the slider guide mechanisms 33 may be one or more. The provision of multiple slider guide mechanisms 33 can effectively improve the stability of the movement of the second nut 322 , which is beneficial to improving the adjustment accuracy of the angle adjustment mechanism 30 .

[0153] In some embodiments, the third connecting member 31 is provided with a first handle 75 to facilitate the use of the flange cover disassembly and assembly device 100 .

[0154] In some embodiments, the lifting drive member 22 is connected to the third connecting member 31 , and the lifting drive member 22 drives the third connecting member 31 to move up and down, thereby driving the supporting unit 42 connected thereto to move up and down.

[0155] In some embodiments, the third connecting member 31 is provided with a second guide rod 24, and the second guide rod 24 is parallel to the lifting direction of the lifting drive member 22. The lifting connecting member 21 is provided with a second guide sleeve 25, and the second guide sleeve 25 is sleeved on the outside of the second guide rod 24. In the process of the lifting drive member 22 driving the third connecting rod to lift and lower, the second guide rod 24 slides in the second guide sleeve 25, thereby guiding the lifting and lowering of the third connecting member 31, making the lifting and lowering of the third connecting member 31 more stable and reliable, which is beneficial to improving the stability of the lifting and lowering of the support unit 42.

[0156] In some embodiments, the number of the second guide rods 24 is one or more, and the plurality of second guide rods 24 are arranged at intervals along the circumference of the lifting drive member 22 to better guide and improve the lifting stability of the support unit 42 and the flange cover 210. For example, the number of the second guide rods 24 is 6, 3 of which are located on one side of the third connecting member 31, and the other 3 are located on the other side of the third connecting member 31.

[0157] In some embodiments, the lifting connection member 21 is provided with a second handle 76 to facilitate personnel to move the lifting connection member 21, thereby driving the positioning member 41 to move.

[0158] In some embodiments, the flange cover disassembly and assembly equipment 100 further includes a second lifting mechanism 60 , which is installed on the base 10 , connected to the horizontal sliding unit 23 , and used to drive the horizontal sliding unit 23 to rise and fall.

[0159] The second lifting mechanism 60 is used to drive the first lifting mechanism 20 to move up and down, thereby driving the support unit 42 and other components to move up and down. Through the cooperation of the first lifting mechanism 20 and the second lifting mechanism 60, two-stage lifting can be achieved to meet the disassembly and assembly requirements of the flange cover 210 at a higher position.

[0160] In some embodiments, the structure of the first lifting mechanism 20 may be the same as or different from the structure of the second lifting mechanism 60 .

[0161] In some embodiments, the second lifting mechanism 60 includes a fourth connecting member 61, a fixed frame 62 and a lifting assembly 63, the lifting assembly 63 includes a double-headed screw 631, two moving blocks 632, two first connecting rods 633 and two second connecting rods 634, the double-headed screw 631 is rotatably installed on the fixed frame 62, the two moving blocks 632 are respectively screwed on both ends of the double-headed screw 631, one end of the two first connecting rods 633 is rotatably connected to the base 10, the other ends of the two first connecting rods 633 are respectively rotatably connected to the two moving blocks 632, one end of the two second connecting rods 634 is rotatably connected to the fourth connecting member 61, and the other ends of the two second connecting rods 634 are respectively rotatably connected to the two moving blocks 632, and the first lifting mechanism 20 is installed on the fourth connecting member 61; by rotating the double-headed screw 631, the two moving blocks 632 are driven to be relatively close or relatively far away, thereby driving the fourth connecting member 61 to rise and fall, and then driving the first lifting mechanism 20 and the support unit 42 connected thereto to rise and fall.

[0162] In some embodiments, the first slide rail 2311 is installed on the fourth connecting member 61 .

[0164] For example, there are two lifting assemblies 63, which are located on opposite sides of the fourth connecting member 61. The ends of the double-headed screw rods 631 of the two lifting assemblies 63 are connected with sprockets 64, and the two sprockets 64 are connected by chains 65. A rotating wheel 66 is provided at the end of one of the double-headed screw rods 631. By rotating the rotating wheel 66, the two double-headed screw rods 631 are driven to rotate synchronously through the cooperation of the chain 65 and the sprocket 64, thereby improving the consistency of the lifting and lowering of the fourth connecting member 61 on both sides, reducing the risk of tilting of the fourth connecting member 61, and helping to improve the stability of the disassembly and assembly of the flange cover 210.

[0167] See also Figure 1 As shown, in some embodiments, a moving wheel 71 is provided at the bottom of the base 10 .

[0168] In the process of removing the flange cover plate 210 by using a winch tool, after the flange cover plate 210 is removed from the housing 220 and moved to a preset position, it is necessary to install a moving wheel 71 to facilitate the movement of the flange cover plate 210. In the embodiment of the present application, the moving wheel 71 can be directly moved to make the moving operation of the flange cover plate 210 simpler. The moving wheel 71 can be a universal wheel, a fixed wheel, etc.

[0169] In some embodiments, the bottom of the base 10 is provided with a support foot 72 with an adjustable height. The base 10 can be lifted by using the support foot 72 with an adjustable height, so that the moving wheel 71 is suspended in the air, reducing the movement of the moving wheel 71 to disassemble and assemble the flange cover 210, and also facilitating the fixed storage of the flange cover 210.

[0170] In some examples, the universal wheels and the directional wheels simultaneously complete the movement of the evaporator flange cover 210 device, and the support feet 72 are used for fixed support when storing the cover flange.

[0171] See also Figure 5 As shown, in some embodiments, the base 10 is provided with a third handle 77 to facilitate the movement of the flange cover disassembly and assembly device 100 .

[0172] See also Figure 1 As shown, in some embodiments, the base 10 is installed with a hoisting frame 73 to facilitate the hoisting and use of the flange cover disassembly and assembly device 100.

[0173] See also Fig.15 and Fig.16 As shown, in some embodiments, the lifting connection member 21 is provided with a ruler 74 to facilitate checking the lifting height of the first lifting mechanism 20 at any time, so as to facilitate the use of the flange cover disassembly and assembly device 100.

[0174] See also Fig.17 As shown, in some embodiments, the lifting drive member 22 is a lifting cylinder 221, the cylinder body of the lifting cylinder 221 is installed on the lifting connecting member 21, the piston rod of the lifting cylinder 221 is connected to the third connecting member 31, and the lifting cylinder 221 drives the third connecting member 31 to rise and fall, thereby driving the supporting unit 42 to rise and fall. The flange cover disassembly and assembly equipment 100 also includes a pneumatic control system 80, which includes an air source, an air-controlled one-way valve 81, a first throttle valve 82, a second throttle valve 83 and a pressure reducing valve 84. The air source is connected to the pilot port (Z port) of the air-controlled one-way valve 81 and the air inlet end of the pressure reducing valve 84 through a three-way connection. The first throttle valve 82, the second throttle valve 83 and the pressure reducing valve 84 are connected in series in sequence. The first throttle valve 82 is connected to the second throttle valve 83 and the air inlet port (P port) of the air-controlled one-way valve 81, and the pressure reducing valve 84 is connected between the second throttle valve 83 and the air source; the air outlet of the air-controlled one-way valve 81 is connected to the lifting cylinder 221.

[0175] One end of the three-way valve is connected to the air source, and the other two ends are respectively connected to the pilot port of the air-controlled one-way valve 81 and the air inlet end of the pressure-reducing valve 84. The pressure-reducing valve 84 is used to control the pressure of the entire pneumatic control system 80. When an external force assists in driving the support unit 42 to rise and fall (for example: when the support plate 421 is in close contact with the flange cover plate 210 or when an external force drives the support unit 42 to rise and fall, etc.), the pressure-reducing valve 84 automatically inhales and exhausts air to maintain the balance of the pneumatic control system 80. The outlet end of the pressure reducing valve 84 is connected to the second throttle valve 83 to control the rising speed of the support unit 42 pushed by the lifting cylinder 221, and the first throttle valve 82 is connected between the second throttle valve 83 and the air inlet of the air-controlled one-way valve 81 to control the descending speed of the support unit 42 pushed by the lifting cylinder 221; when the pneumatic control system 80 is cut off and the pilot port of the air-controlled one-way valve 81 is cut off, the air-controlled one-way valve 81 acts as a one-way valve to lock the gas in the lifting cylinder 221, thereby realizing the function of locking the lifting cylinder 221 by cutting off the gas; when the pneumatic control system 80 is ventilated, the gas released by the air source preferentially enters the pilot port of the air-controlled one-way valve 81, connecting the lifting cylinder 221 with the pneumatic control system 80, and the air-controlled one-way valve 81 is connected to one interface of the lifting cylinder 221, and the other interface of the lifting cylinder 221 is connected to the silencer 85, and the rising and falling actions of the rod of the lifting cylinder 221 are executed by adjusting the pressure of the pressure reducing valve 84.

[0176] In some embodiments, a switch can be set between the first throttle valve 82 and the air-controlled one-way valve 81. When the lifting cylinder 221 is not required to move up and down, the air circuit of the air inlet of the air-controlled one-way valve 81 is cut off to prevent the air inlet pipeline of the air-controlled one-way valve 81 from bursting and causing the lifting cylinder 221 to fall; when the lifting cylinder 221 is required to move up and down, the switch is opened again.
