Description

Technical Field

[0001] This utility model relates to the field of electrolytic cell installation technology, and in particular to a positioning auxiliary device. Background Technology

[0002] Currently, with the continuous development of hydrogen energy technology, the output and installed capacity of electrolyzers are repeatedly reaching new highs. In China, electrolyzers are generally installed vertically. During the installation process, the tensioning screw needs to be threaded through the upper and lower end pressure plates.

[0003] There are two main installation methods for tension screws. One method involves passing the tension screw through the lower end plate before installing the upper end plate, and then positioning and installing the upper end plate. This method is convenient because only one component is passed through at a time, but the drawback is that after passing through the lower end plate, the tension screw is in an unsupported vertical position before installing the upper end plate. Without proper support, the tension screw is prone to tipping over, affecting assembly safety. The other method involves installing the upper and lower end plates first, and then passing the tension screw through in one go. This method provides stable installation, but it requires a high degree of coaxiality between the upper and lower end plates to ensure they are in a coaxial position. Aligning the upper and lower end plates is difficult and time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning auxiliary device with a simple structure, which can effectively position the lower end pressure plate and provide effective fixed support for the tension screw after the tension screw passes through the lower end pressure plate.

[0018] Beneficial effects:

[0019] When using the positioning auxiliary device provided by this utility model, the guide rail is placed on the installation workbench of the electrolytic cell, and the guide rail and the installation workbench are kept coaxial. A lower end pressure plate is supported on the installation workbench, and the lower end pressure plate has a mounting hole for the tension screw to pass through. First, the lower end pressure plate needs to be installed and positioned to ensure that the mounting hole and the positioning ring are coaxial. The positioning pin is passed through the mounting hole, and the slider is moved to adjust the position of the support plate relative to the lower end pressure plate in the axial direction, so that the positioning ring can move to a position directly opposite the positioning pin. After moving into position, the positioning pin passes through the positioning ring and is fixed by the clamping component. At this point, it is ensured that the mounting hole and the positioning ring are coaxial, thus achieving the positioning of the lower end pressure plate. Then, the positioning pin is removed, and the tension screw is passed through the mounting hole and the positioning ring from top to bottom, and fixed with the clamping component. This ensures both the rapid installation of the tension screw and the fixed support of the lower end of the tension screw through the clamping component, effectively improving the efficiency and safety of the tension screw installation.

[0034] Reference Figures 1 to 5As shown, this embodiment provides a positioning auxiliary device for assisting a columnar electrolytic cell. The electrolytic cell includes a lower end pressure plate and a tension screw, and the lower end pressure plate has mounting holes. The positioning auxiliary device includes a moving mechanism 1 and a supporting mechanism 2. The moving mechanism 1 includes a guide rail 11 and a slider 12, with the slider 12 slidably connected to the guide rail 11. The supporting mechanism 2 includes a supporting plate 21 and a positioning ring 22 and a clamping member 23 disposed on the supporting plate 21. The supporting plate 21 is fixedly connected to the slider 12. The positioning ring 22 is used to limit the positioning pin 41 or tension screw 42 passing through the mounting hole, and the clamping member 23 is used to fix and clamp the positioning pin 41 or tension screw 42.

[0035] In this embodiment, when the positioning auxiliary device is in use, the guide rail 11 is placed on the installation workbench 44 of the electrolytic cell, and the guide rail 11 and the installation workbench 44 are kept in a coaxial position. The lower end pressure plate 45 is supported on the installation workbench 44, and the lower end pressure plate 45 is provided with a mounting hole 451 for the tension screw 42 to pass through. First, the lower end pressure plate 45 needs to be installed and positioned to ensure that the mounting hole 451 of the lower end pressure plate 45 and the positioning ring 22 are in a coaxial position. The positioning pin 41 is passed through the mounting hole 451, and the slider 12 is moved to adjust the position of the support plate 21 relative to the lower end pressure plate 45 in the axial direction, so that the positioning ring 22 can move to a position directly opposite the positioning pin 41. After it moves into place, the positioning pin 41 passes through the positioning ring 22 and is fixed by the clamping member 23. At this time, it is ensured that the mounting hole 451 and the positioning ring 22 are in a coaxial position, thus realizing the lower end pressure plate 45. Then, the positioning pin 41 is removed, and the tension screw 42 is passed through the mounting hole 451 and the positioning ring 22 from top to bottom, and fixed with the clamping member 23. This not only ensures the quick installation of the tension screw 42, but also provides fixed support for the lower end of the tension screw 42 through the clamping member 23, effectively improving the efficiency and safety of the installation of the tension screw 42.

[0036] Optionally, the shape of the guide rail 11 can be adapted to the shape of the electrolytic cell. For example, when the shape of the electrolytic cell is circular, the guide rail 11 can be correspondingly set as an annular shape; when the shape of the electrolytic cell is square, the guide rail 11 can be correspondingly set as a square annular shape.

[0037] In this embodiment, the support mechanism 2 further includes a telescopic rod 24, which includes a fixed part 241 and a telescopic part 242 telescopically disposed on the fixed part 241. The fixed part 241 is fixedly connected to the slider 12, and the telescopic part 242 is fixedly connected to the support plate 21. Specifically, the telescopic part 242 telescopically extends relative to the fixed part 241, which can drive the support plate 21 to rise and fall, thereby adjusting the height of the positioning ring 22 and the clamping member 23.

[0038] For example, the telescopic rod 24 is configured as a hydraulically driven telescopic rod 24.

[0039] This embodiment is not limited to this; the support plate 21 can also be raised and lowered by setting components such as telescopic cylinders and linear servo modules.

[0040] In this embodiment, the support mechanism 2 further includes a positioning sleeve 25, which is fixed to the support plate 21. The disc spring assembly 43 can be placed inside the positioning sleeve 25 and supported on the support plate 21, and the positioning sleeve 25 is used to limit the position of the disc spring assembly 43. Specifically, after the upper end pressure plate is installed, the disc spring assembly 43 needs to be installed on the side of the tension screw 42 that extends out of the lower end pressure plate 45. Specifically, the disc spring assembly 43 is placed inside the positioning sleeve 25 and supported on the support plate 21. The positioning sleeve 25 provides circumferential limitation for the disc spring assembly 43 to ensure that the position of the disc spring assembly 43 remains stable. Specifically, after placing the disc spring assembly 43, it is ensured that the disc spring assembly 43 can maintain a coaxial position with the tension screw 42. The telescopic part 242 of the telescopic rod 24 extends out of the fixed part 241. The telescopic rod 24 extends outward, driving the support plate 21 to rise, which in turn drives the disc spring assembly 43 to rise together. During the process, the disc spring assembly 43 is fitted into the end of the tension screw 42 until it contacts the threaded section of the tension screw 42. Then, through on-site operators and equipment, the disc spring assembly 43 is screwed into the threaded section, and finally the installation of the disc spring assembly 43 is completed.

[0041] In this embodiment, the clamping member 23 is detachably mounted on the support plate 21. The positioning sleeve 25 is detachably mounted on the support plate 21. The clamping member 23 and the positioning sleeve 25 share a mounting position on the support plate 21. Specifically, when the positioning sleeve 25 needs to be installed, the clamping member 23 needs to be removed, and the positioning sleeve 25 needs to be installed in the original position of the clamping member 23. This arrangement can utilize the positioning between the positioning ring 22 of the support plate 21 and the mounting hole 451, avoiding the need to move and adjust the positioning of the support plate 21 again. Since the support plate 21 has been positioned previously, the positioning ring 22 is currently also in a coaxial position with the tension screw 42. After the disc spring assembly 43 is placed, the disc spring assembly 43 can also maintain a coaxial position with the tension screw 42.

[0042] In this embodiment, the fixing part 241 is provided with external threads, and the slider 12 is provided with a first threaded hole 121. The fixing part 241 is threadedly connected to the first threaded hole 121. The fixing part 241 and the slider 12 are fixedly connected by the threaded engagement between the external threads and the first threaded hole 121. The structure is simple and easy to assemble and disassemble.

[0043] In this embodiment, the support plate 21 has a first through hole 211, and the telescopic part 242 has a corresponding second threaded hole 2421. The first screw connector 31 passes through the first through hole 211 and is threadedly connected to the second threaded hole 2421. Specifically, the first screw connector 31 is a bolt, which passes through the first through hole 211 and is threadedly connected to the second threaded hole 2421, thereby fixing the support plate 21 and the telescopic part 242, and realizing a fixed connection between the support plate 21 and the telescopic rod 24.

[0044] Optionally, in this embodiment, multiple first through holes 211, second threaded holes 2421, and first screw connectors 31 are provided in a one-to-one correspondence.

[0045] Optionally, the first threaded member 31 can be configured as a bolt or a screw.

[0046] In this embodiment, the support plate 21 has a recessed groove 212, and the positioning ring 22 is supported in the recessed groove 212. The positioning ring 22 has a second through hole 221, and the bottom of the recessed groove 212 has a corresponding third threaded hole 2121. The second screw connector 32 passes through the second through hole 221 and is threadedly connected to the third threaded hole 2121. The recessed groove 212 provides space for the positioning ring 22 to be positioned and installed, ensuring the quick installation of the positioning ring 22. Specifically, the second screw connector 32 is a bolt, which passes through the second through hole 221 and is threadedly connected to the third threaded hole 2121, thereby effectively fixing the support plate 21 and the positioning ring 22.

[0047] Optionally, in this embodiment, multiple second through holes 221, third threaded holes 2121, and second screw connectors 32 are provided in a one-to-one correspondence.

[0048] Alternatively, the second threaded member 32 can be configured as a screw in addition to a bolt.

[0049] In this embodiment, a through hole 2122 is provided at the bottom of the settling tank 212, and the through hole 2122 is arranged to coincide with the axis of the positioning ring 22. The through hole 2122 provides clearance space for the positioning pin 41 and the tension screw 42, allowing the lower ends of the positioning pin 41 and the tension screw 42 to pass through.

[0050] Optionally, the diameter of the through hole 2122 is set to be the same as the inner diameter of the positioning ring 22.

[0051] In this embodiment, the clamping member 23 has a third through hole 231, and the support plate 21 has a corresponding fourth threaded hole 213. The third screw connector 33 passes through the third through hole 231 and is threadedly connected to the fourth threaded hole 213. Specifically, the third screw connector 33 is a bolt, which passes through the third through hole 231 and is threadedly connected to the fourth threaded hole 213, thereby effectively fixing the support plate 21 and the clamping member 23.

[0052] Optionally, in this embodiment, multiple third through holes 231, fourth threaded holes 213, and third screw connectors 33 are provided in a one-to-one correspondence.

[0053] Alternatively, the third threaded member 33 can be configured as a screw in addition to a bolt.

[0054] In this embodiment, the clamping member 23 includes a three-jaw chuck with grippers. Using a three-jaw chuck ensures reliable and stable gripping, and provides rapid operation.

[0055] In this embodiment, multiple support mechanisms are provided, and each support mechanism is provided with at least one slider 12. Specifically, multiple support plates 21, positioning rings 22, and clamping members 23 are provided one-to-one, and each support plate 21 is provided with multiple sliders 12. Specifically, since multiple mounting holes 451 are provided at intervals on each lower end pressure plate 45, multiple tension screws 42 need to be installed accordingly. Therefore, support plates 21 corresponding to the number of mounting holes 451 can be provided, and each support plate 21 is provided with a positioning ring 22 and a clamping member 23, so that the auxiliary installation of multiple tension screws 42 can be realized at the same time, further improving the installation efficiency.
