Description

Technical Field

[0001] This utility model relates to the field of gripping tooling technology, and in particular to a gripping device for electrolytic cell electrode frames. Background Technology

[0002] With hydrogen energy currently serving as a primary energy source for achieving carbon neutrality, reducing its manufacturing costs is becoming an increasingly important issue for manufacturers. Alkaline electrolyzers are a key piece of equipment in hydrogen energy production, and with intensifying product competition, cost-effective electrolyzer manufacturing has become a major focus for manufacturers.

[0003] In existing alkaline electrolytic cells, the electrode plates and nickel wire mesh are fixed by welding during the production process. The product after welding the electrode plates and nickel wire mesh is called a chamber, which is then installed on the electrode frame. During this operation, the chambers and electrode frames need to be transferred to the welding worktable beforehand and arranged according to the structure to facilitate subsequent welding operations. The conventional method of transferring the chambers and electrode frames relies on manual handling, requiring the movement of both the electrode plates and the electrode frame, resulting in low efficiency and high labor intensity for manual handling.

[0004] In addition, there is a method of handling materials that uses hoisting fixtures to connect chains and electromagnets to attract pole frames. This method has the following drawbacks:

[0005] 1. The transfer of electrode frames requires two people working together: one to hold and hold the frame, and the other to operate and move it, resulting in high labor costs and low efficiency. 2. During transfer, uneven stress on the chambers of the electrode frame causes them to wobble, easily leading to the nickel mesh falling off and becoming damaged. 3. The fixture can only lift electrode frames of a fixed diameter and is incompatible with electrolytic cells of different sizes, requiring the use of different fixtures, which increases fixture costs.

[0006] Therefore, there is an urgent need to provide a new type of electrolytic cell electrode frame gripping device to solve the above-mentioned technical problems in the prior art. Utility Model Content

[0007] The purpose of this invention is to provide an electrolytic cell electrode frame gripping device, which has a simple structure and is easy to operate. It can improve the gripping stability of the electrode frame, thereby improving the gripping and handling efficiency. It can also be applied to electrode frames of different sizes, reducing tooling costs.

[0008] To achieve this objective, the present invention adopts the following technical solution:

[0009] The electrolytic cell electrode frame gripping device includes a hoisting body, multiple fixed rods, multiple telescopic rods, and multiple gripping components. The hoisting body is connected to external hoisting equipment. The fixed rods are fixed to the hoisting body, and the multiple fixed rods are evenly spaced along the circumference of the hoisting body. The telescopic rods are slidably inserted into the fixed rods one by one, so that the distance between the first end of the telescopic rod and the hoisting body is adjustable. The gripping components are fixed to the first end one by one. Each gripping component includes an elastic element and a gripping element. One end of the elastic element is fixed to the first end, and the other end is fixed with the gripping element, which is used to grip the electrode frame.

[0010] Optionally, the lifting body includes a lifting ring and a fixing plate. The lifting ring is disposed on one side of the fixing plate and is used to connect with external lifting equipment. The other side of the fixing plate is connected to the fixing rod.

[0011] Optionally, a reinforcing bar is provided between each of the two adjacent fixed bars mentioned above.

[0012] Optionally, a fixing handwheel is threadedly connected to the side wall of the fixing rod, and one end of the fixing handwheel can pass through the side wall of the fixing rod and abut against the telescopic rod.

[0013] Optionally, the side wall of the fixing rod is provided with a plurality of fixing holes at intervals along the length of the fixing rod, and fixing nuts are respectively provided at the positions corresponding to the fixing holes on the outer side wall of the fixing rod, and the fixing handwheel is used to be threadedly connected to any of the fixing nuts.

[0014] Optionally, the gripping element includes a negative pressure suction cup, which is connected to the first end via the elastic element.

[0015] Optionally, the grasping element includes a permanent magnet electromagnet, which is connected to the first end via the elastic element, and the permanent magnet electromagnet loses its magnetism when energized and regains its magnetism when de-energized.

[0016] Optionally, the gripping assembly further includes a connecting rod, one end of which is connected to the first end, and the other end of which is fixed with the elastic element.

[0017] Optionally, an adapter plate is fixed to the other end of the connecting rod. A plurality of elastic elements are fixed to the end of the adapter plate opposite to the connecting rod. The ends of the plurality of elastic elements opposite to the adapter plate are all connected to the same gripping element.

[0018] Optionally, the outer wall of the telescopic rod is provided with scale lines along the length of the telescopic rod.

[0019] Beneficial effects:

[0020] The electrolytic cell electrode frame gripping device of this invention connects to the output end of an external lifting device via a hoisting body for hoisting and transport. The device consists of a fixed rod, a telescopic rod, and a gripping assembly. The fixed rod is fixedly connected to the hoisting body to form an integral frame. The telescopic rod passes through the fixed rod and is slidably connected to it. By sliding the telescopic rod, the distance between the gripping assembly at the first end of the telescopic rod and the hoisting body can be changed. This allows the electrolytic cell electrode frame gripping device to be used with electrode frames of different diameters without requiring additional manufacturing. This electrolytic cell electrode frame gripping device, available in various specifications, reduces tooling costs during hoisting and transportation. When gripping and fixing the electrode frame, a gripping element is used. An elastic element is installed between the gripping element and the first end of the telescopic rod. If the top of the electrode frame deforms and becomes uneven in height, the elastic element's contraction characteristic is used to extend it, causing the gripping element to descend and grip the concave portion, or to compress it, causing the gripping element to rise and grip the convex portion. This prevents the gripping element from being loosely fixed, improving the stability and reliability of the gripping and fixing. This electrolytic cell electrode frame gripping device has a simple structure and is easy to operate. It replaces manual handling of electrolytic cell electrode frames, improves gripping stability, and thus increases gripping and transportation efficiency. It is also applicable to electrode frames of different sizes, reducing tooling costs. Attached Figure Description

[0033] Please refer to Figure 1 and Figure 2In this embodiment, the electrolytic cell electrode frame gripping device includes a hoisting body 100, multiple fixed rods 200, multiple telescopic rods 300, and multiple gripping components 400. The hoisting body 100 is connected to external hoisting equipment. The fixed rods 200 are fixed to the hoisting body 100, and the multiple fixed rods 200 are evenly spaced along the circumference of the hoisting body 100. The telescopic rods 300 are slidably inserted into the fixed rods 200 one by one, so that the distance between the first end 301 of the telescopic rod 300 and the hoisting body 100 is adjustable. The gripping components 400 are fixed to the first end 301 one by one. The gripping components 400 include an elastic element 410 and a gripping element 420. One end of the elastic element 410 is fixed to the first end 301, and the other end is fixed with the gripping element 420. The gripping element 420 is used to grip the electrode frame.

[0034] In this embodiment, the electrolytic cell electrode frame gripping device is connected to the output end of an external hoisting device via a hoisting body 100 for hoisting and transport. The device consists of a fixed rod 200, a telescopic rod 300, and a gripping assembly 400. The fixed rod 200 is fixedly connected to the hoisting body 100 to form an integral frame. The telescopic rod 300 passes through the fixed rod 200 and is slidably connected to it. By sliding the telescopic rod 300, the distance between the gripping assembly 400 at the first end 301 of the telescopic rod 300 and the hoisting body 100 can be changed. This allows the electrolytic cell electrode frame gripping device to be used with electrode frames of different diameters, eliminating the need for... The production of electrolytic cell electrode frame gripping devices of different specifications reduces tooling costs during hoisting and transportation. When gripping and fixing the electrode frame, a gripping element 420 is used. An elastic element 410 is provided between the gripping element 420 and the first end 301 of the telescopic rod 300. When the top of the electrode frame deforms and causes inconsistencies in height, the elastic element 410's contraction characteristic is used to pull it outwards, causing the gripping element 420 to descend and grip the concave portion, or to compress it, causing it to rise and grip the convex portion. This prevents the gripping element 420 from being loosely fixed, improving the stability and reliability of the gripping and fixing. This electrolytic cell electrode frame gripping device has a simple structure and is easy to operate. It replaces manual handling of electrolytic cell electrode frames, improves gripping stability, and thus improves gripping and transportation efficiency. It is also applicable to electrode frames of different sizes, reducing tooling costs.

[0035] The aforementioned external hoisting equipment can be a multi-degree-of-freedom robotic arm or a crane. No specific restrictions are made here, as long as it can lift the electrolytic cell electrode frame gripping device and transport it in both horizontal and vertical directions.

[0036] Please continue to refer to this. Figure 1Multiple fixing rods 200 are provided, and the length direction of each fixing rod 200 passes through the center of the hoisting body 100. In this embodiment, the multiple fixing rods 200 are rod-shaped structures of equal length. After the length direction of each fixing rod 200 passes through the center of the hoisting body 100, the center of gravity of the assembly composed of the multiple fixing rods 200 and the hoisting body 100 is still located on the central axis of the hoisting body 100. After the external hoisting equipment grabs the hoisting body 100, the assembly composed of the multiple fixing rods 200 and the hoisting body 100 can still maintain horizontality and balance, avoiding tilting and swaying, and improving the stability of transportation.

[0037] Furthermore, the aforementioned hoisting body 100 includes a lifting ring 110 and a fixing plate 120. The aforementioned fixing rod 200 is a square steel structure. The lifting ring 110 is disposed on one side of the aforementioned fixing plate and is used to connect with external hoisting equipment. The other side of the aforementioned fixing plate 120 is connected to the aforementioned fixing rod 200. Specifically, the aforementioned fixing rod 200 is welded and fixed to the bottom of the aforementioned fixing plate 120. Furthermore, in this embodiment, the number of fixing rods 200 can be four. Two of the fixing rods 200 are rectangular steel bars with their midpoints located below the lifting ring 110. Two short rectangular steel bars are welded and fixed on both sides of the midpoint of the rectangular steel bar to form the remaining two fixing rods 200. A screw rod is inserted from bottom to top through the midpoint of the rectangular steel bar. The screw rod passes through the rectangular steel bar, the fixing plate 120, and the lifting ring 110 in sequence, and the top of the screw rod is threaded to the lifting ring 110, thereby fixing the lifting ring 110, the fixing plate 120, and the four fixing rods 200. In order to further improve the fixing effect, the sides of the four fixing rods 200 are welded to the bottom wall of the fixing plate 120 in sequence, which will not be described in detail here.

[0038] Please continue to refer to this. Figure 1 A reinforcing rod 230 is provided between each pair of adjacent fixed rods 200. It should be noted that, to improve the structural stability of the four fixed rods 200, the electrolytic cell electrode frame gripping device further includes four reinforcing rods 230. These reinforcing rods 230 are clamped one-to-one between adjacent fixed rods 200, forming a square. The arrangement of the reinforcing rods 230 ensures that the two adjacent fixed rods 200 and the reinforcing rods 230 between them form a triangle, thereby improving the stability between adjacent fixed rods 200, preventing rotation of the fixed rods 200, and increasing the structural strength and service life of the electrolytic cell electrode frame gripping device.

[0039] It should be noted that the aforementioned fixing rods 200 can also be provided in 3, 5, 6, 8, etc., as long as they are evenly spaced. It can be imagined that the shape formed by the aforementioned reinforcing rods 230 is an equilateral triangle, a regular pentagon, a regular hexagon, or a regular octagon, which will not be elaborated here.

[0040] Optionally, the gripping element 420 can be either a permanent magnet electromagnet or a negative pressure suction cup. The permanent magnet electromagnet is connected to the first end 301 via the elastic element 410. The permanent magnet electromagnet generates magnetic force through the periodic changes of energization and de-energization, and uses the magnetic force to attract and fix the iron pole frame. The negative pressure suction cup is connected to the first end 301 via the elastic element 410, and uses the negative pressure suction force generated by the vacuum device to attract and fix the smooth surface pole frame. Both methods can achieve reliable fixation and facilitate release, enabling timely unloading and improving the efficiency of material handling.

[0041] like Figure 2 As shown, the gripping element 420 is a permanent magnet electromagnet. This permanent magnet electromagnet loses its magnetism when energized and regains its magnetism when the power is off. Because the gripping element 420 loses its magnetism when energized and regains its magnetism when the power is off, it can only attract and fix the pole frame when the power is off. This avoids the permanent magnet electromagnet losing its magnetism due to a sudden power outage, and prevents the pole frame and the small cells on the pole frame from falling off when the power is interrupted, thus improving reliability.

[0042] Furthermore, the aforementioned gripping assembly 400 also includes a connecting rod 430. One end of the connecting rod 430 is connected to the first end 301 of the telescopic rod 300, and the other end of the connecting rod 430 is fixed with the aforementioned elastic element 410. Furthermore, the connecting rod 430 is a bolt structure, with adapter nuts 432 fixed at both the top and bottom of the bolt. The two adapter nuts 432 abut against the upper and lower outer walls of the telescopic rod 300 respectively, thus fixing the connecting rod 430 to the first end 301 of the telescopic rod 300. This allows for timely replacement and maintenance of the gripping assembly 400, improving the convenience of maintenance; and facilitates the replacement of gripping elements 420 of different sizes, enabling gripping and fixing of pole frames of different sizes and specifications.

[0043] Furthermore, to prevent the adapter nut 432 from loosening after prolonged use, the adapter nut 432 is provided with an opening, and the connecting rod 430 is provided with an anti-loosening pin. The anti-loosening pin passes through the adapter nut 432 and the connecting rod 430 in sequence to prevent the connecting rod 430 and the adapter nut 432 from loosening.

[0044] In this embodiment, an adapter plate 431 is fixed to the other end of the connecting rod 430. A plurality of spaced elastic elements 410 are fixed to the end of the adapter plate 431 facing away from the connecting rod 430. The ends of the multiple elastic elements 410 facing away from the adapter plate 431 are all connected to the same gripping element 420. By evenly spaced fixing multiple elastic elements 410 to the bottom of the adapter plate 431, and using multiple elastic elements 410 to fix the gripping element 420, the tension on each elastic element 410 can be dispersed, making the force on the adapter plate 431 and the gripping element 420 more uniform, preventing the frame from shaking during transport, and improving stability during transport.

[0045] like Figure 3 As shown, optionally, a fixing handwheel 210 is threadedly connected to the side wall of the fixing rod 200. One end of the fixing handwheel 210 can pass through the side wall of the fixing rod 200 and abut against the telescopic rod 300. Specifically, the fixing handwheel 210 is located on the top wall of the fixing rod 200, thus facilitating manual adjustment of the fixing handwheel 210. After adjusting the extension length of the telescopic rod 300, the fixing handwheel 210 can be manually tightened so that the bottom of the fixing handwheel 210 abuts against the telescopic rod 300, thereby fixing the position of the telescopic rod 300 and preventing the telescopic rod 300 from retracting or extending after adjustment, thus improving the adjustment accuracy of the electrolytic cell electrode frame gripping device. Moreover, compared with using hydraulic or electric adjustment of the telescopic rod 300, manual adjustment has the advantage of less contamination, avoiding contamination and damage to the chambers on the electrode frame, and its reliability is higher.

[0046] In this embodiment, the sidewall of the fixed rod 200 is provided with a plurality of fixing holes 220 at intervals along the length of the fixed rod 200. Fixing nuts 221 are provided at positions on the outer sidewall of the fixed rod 200 corresponding to the fixing holes 220. The fixing handwheel 210 is used for threaded connection with any of the fixing nuts 221. Since the telescopic rod 300 slides within the fixed rod 200, the position of the end of the telescopic rod 300 within the fixed rod 200 changes constantly. Therefore, it is necessary to adjust the position of the fixing handwheel 210 so that the end of the fixing handwheel 210 can abut against the telescopic rod 300 and fix the telescopic rod 300. Therefore, fixing holes 220 are provided on the outer wall of the fixed rod 200, and fixing nuts 221 are provided in the fixing holes 220. By threading the fixing handwheel 210 with fixing nuts 221 at different positions, the position of the fixing handwheel 210 can be changed, thereby expanding the adjustment range of the extension size of the telescopic rod 300 and further expanding the applicability of the electrolytic cell electrode frame gripping device.

[0047] It should be noted that in this embodiment, the fixing hole 220 and the fixing nut 221 are both provided on the top wall of the fixing rod 200, which facilitates adjustment, and will not be described in detail here.

[0048] Please continue to refer to this. Figure 1 and Figure 3 Multiple fixing handwheels 210 are provided, and the bottom of each fixing handwheel 210 can abut against the outer wall of the telescopic rod 300. Specifically, in this embodiment, each fixing rod 200 is provided with three fixing handwheels 210. After the extension length of the telescopic rod 300 is adjusted, the three fixing handwheels 210 can be tightened in sequence with suitable fixing nuts 221, so that the bottom of each fixing handwheel 210 can abut against the outer wall of the telescopic rod 300. The abutting and fixing effect of multiple fixing handwheels 210 can achieve more reliable fixation of the telescopic rod 300 and improve the stability of the telescopic rod 300 after the extension size is adjusted.

[0049] In a preferred embodiment, the outer wall of the telescopic rod 300 is provided with scale lines 310 along the length direction of the telescopic rod 300. Before adjusting the telescopic rod 300, it is necessary to first measure the radius or diameter of the pole frame, and then pull out the telescopic rod 300 so that the scale lines 310 on the telescopic rod 300 shown at the end of the fixed rod 200 correspond to the size setting of the pole frame, thereby achieving precise adjustment of the extension size of the telescopic rod 300.

[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
