[0002] With the country's advocacy of energy conservation and emission reduction, the development of green energy has become a top priority, among which hydrogen energy is valued by people and has always been regarded as an ultimate energy source. Among them, water electrolysis to produce hydrogen plays a pivotal role in the field of hydrogen energy, and the electrolyzer is the core equipment of the water electrolysis hydrogen production system. Whether the equipment assembly work is completed well will directly affect the performance of the equipment. The rapid development of water electrolysis to produce hydrogen has made the market demand for large electrolyzers more intense. At present, there is no relatively mature and simple assembly method for large electrolyzers, and some steps are still in a relatively primitive operation method. It is particularly important to use tooling in the assembly to complete the work efficiently in different assembly environments. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] like Figure 1-4 As shown, a processing tool for vertically assembling fasteners of an alkaline water electrolyzer comprises:

[0028] A pole plate 9 stacked between an upper pressure plate 7 and a lower pressure plate 10 arranged in parallel;

[0029] The tension bolts 6 are passed through the upper pressure plate 7 and the lower pressure plate 10 and arranged along their contours to tighten and limit the stacked plates 9;

[0030] The tension bolts 6 are respectively provided with disc spring assemblies 18 which are arranged in a stacked manner and fixed to the upper end pressure plate 7 / the lower end pressure plate 10 through the tension nuts 5.

[0031] As an embodiment further provided by the present invention, it also includes:

[0032] A tooling lifting lug 1 mounted on a first end of a tensioning bolt 6;

[0033] The U-shaped shackles 3 arranged at both ends of the steel wire rope 4 are assembled on the hanging ears symmetrically opened on the tooling lifting ears 1.

[0034] Secondly, the tooling lifting eye 1 includes a fixing sleeve 2 sleeved on the first end of the tensioning bolt 6 .

[0035] As another embodiment further provided by the present invention, it includes a disc spring barrel 13 rotatably assembled by a fixing pin 16, and a disc spring assembly 18 is composed of disc springs stacked in the disc spring barrel 13;

[0036] The two disc spring tubes 13 are also provided with a movable latch 17 for locking the two into a hoop.

[0037] Secondly, the outer arc top of the disc spring tube 13 is provided with a hand rod sleeve 14 for inserting the hand rod 15.

[0038] As another embodiment further provided by the present invention, it also includes a support platform 12 on which a plurality of vertical poles are arranged, and the lower end pressure plate 10 is placed on the vertical poles.

[0039] Furthermore, a supporting platform support plate 11 is slidably arranged on the plurality of upright poles.

[0040] How to use the tooling for installing the tension bolt 6 under different working conditions:

[0041] 1. If there is enough lifting height in the hoisting environment: After the upper and lower pressure plates 10 and the plate 9 of the electrolytic cell are all stacked, the tension bolts 6 can be installed. Figure 1 First, insert the tension bolt tooling from the top of the tension bolt 6, and tighten the tension nut 5 to the reserved length calculated by the top bolt, and then use the matching U-shaped shackle 3 to connect the two ends of the sling wire rope 4 to the two side ears 1 of the tooling. Finally, pull out the movable pin 17 in the disc spring assembly 18 tooling to open the tooling, and press the disc spring assembly 18 Figure 4 Put them into the disc spring tube 13 in sequence, close the tooling after inspection, insert the movable latch 17 and put them aside. Use the crane to lift the tensioning bolt 6 through the sling wire rope 4. At this time, the bolt will be in a vertical state due to gravity. Adjust the crane to align the bolt with the bolt hole of the upper pressure plate 7, operate the crane to make the tensioning bolt 6 drop vertically, and it can easily pass through the bolt hole of the upper pressure plate 7. During the descent, install the insulating sleeve 8, and continue to drop through the bolt hole of the lower pressure plate 10 in the same way as passing through the bolt hole of the upper pressure plate. Then place the spare disc spring assembly tooling that has passed the inspection on the support platform support plate 11 directly below the tensioning bolt 6, and operate the crane to make the tensioning bolt 6 drop vertically through the disc spring assembly 18. Lift the disc spring assembly tooling through the hand lever 15 so that its height reaches the reserved height of the lower disc spring assembly 18, and then tighten the tensioning nut 5. Use the support platform support plate 11 to hold the bottom bolt, pull out the movable pin 17 of the disc spring assembly tooling, remove the disc spring assembly tooling, and then hang the driving car to the bottom, remove the tension bolt 6 tooling, and then complete the installation of this tension bolt 6 and the lower disc spring assembly 18. According to this method, complete the installation of the remaining tension bolts 6 and the lower disc spring assembly 18 in sequence, and finally install the upper disc spring assembly 18 to complete the vertical installation of the electrolytic cell fasteners.

[0042] 2. In the case of limited lifting height in the lifting environment: After the lower pressure plate 10 and the plate 9 of the electrolytic cell are stacked, the tension bolt 6 can be installed. After the tension bolt 6 is installed, the upper pressure plate 7 can be installed. Figure 2 First, insert the tension bolt tooling from the top of the tension bolt 6, and twist the tie rod nut to the reserved length calculated by the top bolt, and then use the matching U-shaped shackle 3 to connect the two ends of the sling wire rope 4 to the two side ears 1 of the tooling. Finally, pull out the movable pin 17 in the disc spring assembly tooling to open the tooling, and press the disc spring assembly 18 Figure 4Put them into the disc spring tube 13 in sequence, close the tooling after inspection, insert the active latch 17 and put them aside. Use the crane to lift the tension bolt 6 through the sling wire rope 4. At this time, the bolt will be in a vertical state due to gravity. Adjust the crane to align the bolt with the bolt hole of the lower pressure plate 10, operate the crane to make the tension bolt 6 drop vertically, and then easily pass through the bolt hole of the lower pressure plate 10. Then place the spare disc spring assembly tooling after inspection on the support platform support plate 11 just below the tension bolt 6, and operate the crane to make the tension bolt 6 drop vertically through the disc spring assembly 18. Lift the disc spring assembly tooling through the hand lever 15 to make its height reach the reserved height of the lower disc spring assembly 18, and then tighten the tension nut 5. Use the support platform support plate 11 to support the bottom bolt, pull out the active latch 17 of the disc spring assembly tooling, remove the disc spring assembly tooling, and then drop the crane wire rope to the bottom. After removing the tension bolt 6 tooling, the installation of this tension bolt 6 and the lower disc spring assembly 18 is completed. According to this method, the installation of the remaining tension bolts 6 and the lower disc spring assembly 18 is completed in sequence, and finally the upper end pressure plate 7 and the upper disc spring assembly 18 are installed to complete the vertical installation of the electrolytic cell fasteners.

[0043] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
