[0001] This application relates to the field of filter element disassembly and assembly auxiliary equipment, and in particular to a docking auxiliary device for filter element replacement equipment. Background Technology

[0002] In nuclear and chemical industries, filtration equipment is typically required to filter toxic and hazardous substances. The filter cartridges in these systems need frequent replacement; however, due to various limitations in these environments, such as confined space, high radiation levels, and the presence of toxic and hazardous substances, manual replacement is often not feasible. Therefore, highly automated filter cartridge replacement equipment is typically used for the installation and removal of the cartridges.

[0003] During the automated installation and removal of filter cartridges, precise alignment of the filter cartridge replacement equipment with the flange at the filter cartridge installation location is required to ensure the accuracy of the connection between the gripper inside the replacement equipment and the filter cartridge. However, this type of filter cartridge replacement equipment weighs over ten tons, making precise alignment impossible during direct hoisting. Auxiliary equipment is needed to adjust the position of the replacement equipment before lowering it to align with the flange at the filter cartridge installation location. Due to construction process issues, the ground at the filter cartridge installation location may not be level, potentially causing the replacement equipment to tilt during the lowering and alignment process, thus posing a risk of tipping over.

[0004] In summary, there is a need for a docking auxiliary device that can ensure the docking accuracy of filter replacement equipment and the stability of the docking process. Utility Model Content

[0043] Example

[0044] This embodiment provides a docking auxiliary device for filter replacement equipment, referring to... Figure 1 As shown, it includes a base plate assembly 100, a vertical adjustment assembly 300, and a horizontal adjustment assembly 200. (Refer to...) Figure 2 As shown, the base plate assembly 100 has a mating groove 110 in the middle for mates with the flange at the filter element mounting location. The flange is inserted into the mating groove 110 for initial positioning.

[0045] Specifically, refer to Figure 4As shown, the vertical adjustment assembly 300 includes a first adjustment plate 330, a lifting component 310, and a base 350. The first adjustment plate 330 is connected to the base plate assembly 100, with the base plate assembly 100 positioned in the middle of the first adjustment plate 330. Lifting components 310 are connected to the four corners of the first adjustment plate 330. The lifting component 310 is connected to the base 350 via a flexible connection node 320, which allows the lifting component 310 to deflect relative to the base 350. The base 350 is directly supported on the ground. By providing the flexible connection node 320 at the bottom of the lifting component 310, when the ground is not perfectly level due to construction factors, the lifting component 310 can be adjusted to a vertical position via the flexible connection node 320.

[0046] Specifically, refer to Figure 3 As shown, the horizontal adjustment assembly 200 includes a second adjustment plate 240 and a third adjustment plate 230. The second adjustment plate 240 is connected to the first adjustment plate 330 via an X-axis adjustment member 210, allowing the second adjustment plate 240 to be movably mounted on the first adjustment plate 330 along the X-direction. The third adjustment plate 230 is connected to the second adjustment plate 240 via a Y-axis adjustment member 220, allowing the third adjustment plate 230 to be movably mounted on the second adjustment plate 240 along the Y-direction. Both the X-axis adjustment member 210 and the Y-axis adjustment member 220 can be guided by a sliding rail and slider mechanism and driven by a lead screw, hydraulic cylinder, or electric cylinder. The top of the third adjustment plate 230 is provided with a locking member 231 that engages with the filter element replacement device 600; the third adjustment plate 230 supports the filter element replacement device 600. The vertical adjustment component 300 can adjust the horizontal adjustment component 200 to a horizontal state, thereby ensuring that the center of gravity always descends vertically and preventing the extremely heavy filter replacement device 600 from tipping over due to changes in the center of gravity during descent.

[0047] Specifically, the first adjusting plate 330, the second adjusting plate 240, and the third adjusting plate 230 are all provided with through grooves in the middle to accommodate the filter element replacement device 600. During auxiliary docking, the filter element replacement device 600 can be partially placed in the through groove.

[0048] This embodiment provides a docking auxiliary device for a filter element replacement device 600. The angle of the lifting components 310 is adjusted via a flexible connecting node 320 located below the lifting components 310, ensuring that each lifting component 310 is vertical. Even when the ground is not level, the first adjusting plate 330 can be adjusted to a horizontal position, preventing the filter element replacement device 600 from tilting and ensuring that the center of gravity of the filter element replacement device 600 remains vertical during the descent docking process, thus preventing overturning. The docking groove 110 on the base plate assembly 100 is used for initial docking with the flange at the filter element installation location, and the horizontal adjustment assembly 200 adjusts the horizontal position of the filter element replacement device 600, ensuring the docking accuracy between the gripper and the filter element. It should be noted that the docking groove 110 and the flange have a clearance fit to facilitate subsequent horizontal adjustment.

[0049] Specifically, the flexible node can be a ball joint or a universal joint.

[0050] Specifically, the third adjusting plate 230 is provided with engaging parts 231 around its perimeter, and each engaging part 231 has a U-shaped groove. The filter element replacement device 600 has a support column 610 on its side wall, which engages within the U-shaped groove. After the vertical adjusting assembly 300 is leveled, the filter element replacement device 600 is hoisted onto the docking auxiliary device, allowing part of the filter element replacement device 600 to enter the through grooves of each adjusting plate. This causes the support column 610 on the side wall of the filter element replacement device 600 to engage within the U-shaped groove, thereby placing the filter element replacement device 600 onto the docking auxiliary device.

[0051] Specifically, the diameter of the docking groove 110 gradually decreases from bottom to top, so that the side wall of the docking groove 110 forms a guide structure, thereby facilitating the docking of the docking groove 110 with the flange.

[0052] Specifically, the top of the third adjusting plate 230 is provided with a pad 232; a connecting block 620 that abuts against the pad 232 is connected to the side wall of the filter element replacement device 600. The contact area is increased by the pad 232 abutting against the connecting block 620, so as to avoid the support column 610 breaking due to insufficient force area.

[0053] Specifically, refer to Figure 5As shown, the upper surface of the base plate assembly 100 is provided with a groove, which is located outside the docking groove 110. A vision sensor 400 is installed in the groove, facing the center of the base plate assembly 100, for visually detecting the relative position of the filter element replacement device 600 and the flange, thereby enabling more accurate and faster adjustment of the docking between the filter element replacement device 600 and the flange. During the detection process, the docking features respectively set on the filter element replacement device 600 and the flange can be used for judgment.

[0054] Specifically, an illumination unit 410 is also installed in the groove, which facilitates clearer observation of the relative position of the filter replacement device 600 and the flange.

[0055] Specifically, continue to refer to Figure 1 As shown, the first adjusting plate 330 has limiting posts 340 at each of its four corners; the lifting component 310 is installed inside the limiting posts 340 and extends outward from the limiting posts 340; the second adjusting plate 240 has a first notch at each of its four corners, and the third adjusting plate 230 has a second notch at each of its four corners; the limiting posts 340 pass through the first and second notches to restrict the horizontal movement of the second adjusting plate 240 and the third adjusting plate 230. The limiting posts 340 can restrict the horizontal position of the adjusting plates, preventing over-adjustment and subsequent disengagement.

[0056] Specifically, the lifting component is a hydraulic cylinder, an electric cylinder, or a lead screw.

[0057] Specifically, it also includes a control system 500, which is connected to the X-axis adjustment component 210, the Y-axis adjustment component 220, each lifting component 310, the vision sensor 400, etc., and is used to control the actions of each component respectively.

[0058] Docking process:

[0059] The auxiliary docking device is hoisted to the filter element installation position, and the flange is made to mate with the docking groove 110 for initial docking.

[0060] By driving each lifting component 310 to rise and fall, the first adjusting plate 330 is adjusted to a horizontal state. Under the constraint of the first adjusting plate 330 and the base plate assembly 100, the different lifting components 310 will deflect around the flexible connection node 320 by a corresponding angle, so that each lifting component 310 is in a vertical state.

[0061] The filter element replacement device 600 is hoisted, so that the support column 610 engages with the locking piece 231, the connecting block 620 abuts against the pad block 232, and the filter element replacement device 600 is partially inserted into the through groove in the middle of each adjusting plate.

[0062] With the assistance of the vision sensor 400, the horizontal adjustment component 200 adjusts the X and Y positions of the third adjustment plate 230, thereby adjusting the horizontal position of the docking auxiliary device and achieving precise docking between the filter element replacement device 600 and the flange.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
