[0037] The anti-side slip mechanism 4 includes a mounting groove 401, which can provide an installation position. The mounting groove 401 is opened inside the mounting box 2. The internal sliding connection of the mounting groove 401 is a limited sliding plate 402. The limited sliding plate 402 has a limiting function and a sealing function. The side of the limited sliding plate 402 away from the pre-installation mechanism 6 is fixedly connected to a connecting plate 403. The connecting plate 403 plays a connecting role. The side of the connecting plate 403 away from the limiting sliding plate 402 is fixedly connected to an anti-side sliding plate 404. The side slide plate 404 is made of flexible material, so as to prevent the electrode plate 10 from sliding sideways. Two tension springs 405 are arranged inside the mounting groove 401. The tension spring 405 can pull the limiting sliding plate 402, the connecting plate 403 and the anti-side slide plate 404 to reset. The side of the limiting sliding plate 402 away from the anti-side slide plate 404 is fixedly connected to two triangular blocks 406. One end of the tension spring 405 is fixedly connected to the side of the limiting sliding plate 402 away from the connecting plate 403, and the other end of the tension spring 405 is fixedly connected to the inside of the mounting groove 401.

[0038] The driving mechanism 5 includes two sealing sleeves 501. The sealing sleeves 501 can maintain sealing while playing the role of installation, preventing the electrolyte from entering the interior of the installation box 2. The bottoms of the two sealing sleeves 501 are fixedly connected to the two ends of the top of the installation box 2. A sliding rod 502 is slidably connected between the interiors of the two sealing sleeves 501. The sliding rod 502 can play the role of connection. The bottom of the sliding rod 502 is fixedly connected to two driving rods 503. The driving rod 503 has the function of connection. The bottom of the driving rod 503 is fixedly connected to a triangular block 2 504. The triangular block 2 504 can push the triangular block 1 406 to move outward. Two sliding limit grooves 505 are provided on the top of the installation box 2. The driving rod 503 is slidably connected to the sliding limit groove 5 05, one end of the sliding rod 502 is fixedly connected to two locking blocks 506, and the sliding rod 502 is rotatably connected to the side of the locking block 506 with a rotating splicing sleeve 507, which provides an installation position, and the rotating splicing sleeve 507 is provided with two rotating slots 508, which can be engaged with the locking block 506, so as to realize the connection of the sliding rod 502, and the rotating splicing sleeve 507 is provided with a torsion spring 509. The reaction force of the torsion spring 509 can drive the rotating splicing sleeve 507 to reverse, so as to realize the engagement of the rotating slot 508 with the locking block 506, and the rotating splicing sleeve 507 is provided with a limited rotating plate 510. The limited rotating plate 510 has a limiting function, and the sliding rod 502 The end away from the locking block 506 is fixedly connected to the middle of the limiting rotating plate 510, and the locking block 506 is engaged with the rotating slot 508. One of the rotating splicing sleeves 507 is slidably connected to the output end of the hydraulic cylinder, and one end of the torsion spring 509 is fixedly connected to the inside of the rotating splicing sleeve 507. The other end of the torsion spring 509 is fixedly connected to the end of the limiting rotating plate 510 away from the locking block 506. The bottom of the sealing sleeve 501 is set above the sliding limit slot 505, driving the rod 503 to be slidably connected to the inside of the sealing sleeve 501. After the installation box 2 is spliced, the sliding rod 502 can be moved in the direction away from the installation plate 7 first, so that there will be no motion interference between the multiple rotating splicing sleeves 507 and the sliding rod 502. When the cam 507 is in the state of being rotated, the spring 509 is pressed against the spring 509 and the locking block 506 is forced to slide into the locking groove 508. When the cam 507 is in the state of being rotated, the locking block 506 is forced to slide into the locking groove 508. When the cam 507 is in the state of being rotated, the locking block 506 is forced to slide into the locking groove 508.At this time, the hydraulic cylinder in the mounting plate 7 is started, and the output end of the hydraulic cylinder extends, thereby driving the multiple sliding rods 502 to move in the direction away from the mounting plate 7, and then driving the driving rod 503 to move, and the driving rod 503 drives the triangular block 2 504 to move, and then the triangular block 1 406 can be squeezed. After the triangular block 1 406 is squeezed, it can drive the triangular block 1 406 to move in the direction close to the anti-side slide plate 404, and then drive the limiting sliding plate 402, the connecting plate 403 and the anti-side slide plate 404 to move in the direction away from the pre-installation mechanism 6, The anti-side slide plate 404 can squeeze the side of the electrode plate 10, thereby preventing the electrode plate 10 from sliding sideways. When squeezing the side of the electrode plate 10 is no longer needed, the hydraulic cylinder is started again, and the output end of the hydraulic cylinder is retracted, thereby driving the sliding rod 502, the driving rod 503 and the second triangular block 504 to move in the opposite direction, so that the second triangular block 504 no longer squeezes the first triangular block 406. At this time, the tension of the tension spring 405 pulls the limiting sliding plate 402 back, and then the connecting plate 403 and the anti-side slide plate 404 can be pulled back. At this time, the electrode plate 10 can be easily removed and replaced.

[0039] The pre-installation mechanism 6 includes a plurality of installation sleeves 601, which provide installation positions. The exteriors of the plurality of installation sleeves 601 are fixedly connected to the side of the installation box 2 away from the anti-side slide 404. The interior of the installation sleeve 601 is slidably connected to an exhaust plug 602, which has the function of a piston. The exhaust plug 602 is fixedly connected to a connecting column 603 on the side close to the anti-side slide 404. The connecting column 603 has a connecting function. The exterior of the installation sleeve 601 is fixedly connected to a fixing cylinder 604, which provides an installation position. An enlarged groove 605 is provided inside the fixing cylinder 604. The side of the fixing cylinder 604 away from the installation sleeve 601 is fixedly connected to a mounting bracket 606, which provides an installation position. The mounting bracket 606 is close to the installation sleeve 6 One side of 01 is fixedly connected to a limiting column 607, which has a limiting function. The outside of the limiting column 607 is slidably connected to a plug plate 608, which can plug the communicating air pipe 610, so that the communicating air pipe 610 can be blocked at the air inlet of the communicating air pipe 610 when inhaling, preventing external air from entering the interior of the mounting sleeve 601. A push spring 609 is provided inside the expansion groove 605, and the push spring 609 can use its own elastic force to reset the plug plate 608 when there is no gas push. The interior of the fixed cylinder 604 is fixedly connected to the communicating air pipe 610, which can play a role in ventilation. The end of the communicating air pipe 610 away from the plug plate 608 is fixedly connected to the interior of the mounting sleeve 601, and the plug plate 608 is slidably connected to the interior of the fixed cylinder 604, and one end of the push spring 609 is fixedly connected to the interior of the fixed cylinder 604, and the other end of the push spring 609 is fixedly connected to the end of the plug plate 608 away from the communicating air pipe 610. When pre-installing the installation box 2, first, after the installation box 2 is closely attached to the inner wall of the groove body 1 and in the marked position, the sliding rod 502 is pushed in the direction away from the installation plate 7, thereby driving the limiting sliding plate 402 to move in the direction away from the pre-installation mechanism 6, and then pulling the connecting column 603 and the air extraction plug 602 to move in the direction of the anti-side slide plate 404. At this time, the air pressure in the installation sleeve 601 becomes smaller, and at the same time, due to the blocking of the plug plate 608, the gas will not enter the interior of the installation sleeve 601 from the outside. Then the installation box 2 can be adsorbed on the inner wall of the groove body 1. At this time, the installation of the installation box 2 is completed, and the welding of the installation box 2 can be conveniently carried out. After welding, if the anti-side slide plate 404 needs to be moved in the direction of the pre-installation mechanism 6, it can drive the limiting sliding plate 402, the connecting column 603 and the exhaust plug 602 to move away from the anti-side slide plate 404. At this time, the gas in the installation sleeve 601 will enter the interior of the fixed cylinder 604 through the communicating air pipe 610, thereby pushing the plug plate 608 to overcome the elastic force of the pushing spring 609 and move in the direction of the communicating air pipe 610. At this time, after the plug plate 608 moves into the interior of the expanded groove 605, the gas will be discharged from the interior of the expanded groove 605 to the outside of the installation sleeve 601.This prevents the internal air pressure of the mounting sleeve 601 from increasing, further preventing the mounting box 2 from being desoldered.

[0040] A welding and installation process for an electrolytic cell anti-skid device includes the following steps:

[0041] Step 1: Mark the installation position according to the drawing, use the pre-installation mechanism 6 to pre-install the device inside the tank body 1, and then calibrate it with a laser level to ensure that the parallelism deviation between the device and the plate reference surface is ≤0.5mm, and adjust it to a horizontal level;

[0042] Step 2: Assemble the installation box 2 according to the length of the trough body 1, and weld after splicing a section, or first splice the installation box 2 according to the length of the trough body 1 and then weld. When welding, use a symmetrical segmented welding method, first spot weld the four corners of the device to fix the position, and then perform continuous welding in an alternating diagonal manner;

[0043] Step 3: Perform ultrasonic testing on the weld, polish the surface to Ra < 1.6μm, remove welding slag and stress concentration points, and finally spray epoxy anti-corrosion coating to ensure the corrosion resistance and structural reliability of the device.

[0044] When the locking plate 306 is in the state of being pressed down, the locking plate 305 is pressed downwardly and the locking plate 306 is pressed downwardly.

[0045] After the installation box 2 is spliced, the sliding rod 502 can be moved away from the installation plate 7, so that there will be no motion interference between the multiple rotating splicing sleeves 507 and the sliding rod 502. After the installation box 2 is spliced, the sliding rod 502 is moved toward the installation plate 7, and the rotating splicing sleeve 507 is rotated so that the through grooves on the rotating splicing sleeve 507 are arranged vertically. When the rotating splicing sleeve 507 is rotated, the torsion spring 509 can be compressed, and then the through grooves on the rotating splicing sleeve 507 can be rotated. The groove slides into the outside of the locking block 506. At this time, the locking block 506 is located in the inside of the rotating slot 508. The rotating splicing sleeve 507 is loosened and the reaction force of the torsion spring 509 can drive the rotating splicing sleeve 507 to rotate in the opposite direction, and make the locking block 506 slide into the inside of the rotating slot 508, thereby completing the splicing between multiple sliding rods 502, and also completing the splicing of the output end of the hydraulic cylinder with one of the sliding rods 502. At this time, the hydraulic cylinder in the mounting plate 7 is started, and the output end of the hydraulic cylinder extends, thereby driving multiple sliding rods 502 to move. The rod 502 moves in the direction away from the mounting plate 7, and then can drive the driving rod 503 to move, and the driving rod 503 drives the triangular block 2 504 to move, and then can squeeze the triangular block 1 406. After the triangular block 1 406 is squeezed, it can drive the triangular block 1 406 to move in the direction close to the anti-side slide plate 404, and then can drive the limiting sliding plate 402, the connecting plate 403 and the anti-side slide plate 404 to move in the direction away from the pre-installation mechanism 6, so that the anti-side slide plate 404 can squeeze the electrode plate 10, and then can prevent the electrode plate 10 from sliding sideways. When there is no need to squeeze the side of the electrode plate 10, the hydraulic cylinder is started again, and the output end of the hydraulic cylinder is retracted, thereby driving the sliding rod 502, the driving rod 503 and the triangular block 2 504 to move in the opposite direction, so that the triangular block 2 504 can no longer squeeze the triangular block 1 406. At this time, the limiting sliding plate 402 is pulled back under the tension of the tension spring 405, and then the connecting plate 403 and the anti-side sliding plate 404 can be pulled back. At this time, the electrode plate 10 can be easily taken out and replaced;

[0046] When pre-installing the installation box 2, first place the installation box 2 close to the inner wall of the groove body 1 at the marked position, and then push the sliding rod 502 in the direction away from the installation plate 7, so as to drive the limiting sliding plate 402 to move away from the pre-installation mechanism 6, and then pull the connecting column 603 and the exhaust plug 602 to move in the direction of the anti-side slide plate 404. At this time, the air pressure in the installation sleeve 601 becomes smaller, and at the same time, due to the blocking of the plug plate 608, the air will not enter the interior of the installation sleeve 601 from the outside, and then the installation box 2 can be adsorbed on the inner wall of the groove body 1. At this time, the installation of the installation box 2 is completed, and the welding of the installation box 2 can be conveniently carried out. After welding, If the anti-side slide plate 404 needs to be moved toward the pre-installation mechanism 6, it can drive the limiting sliding plate 402, the connecting column 603 and the exhaust plug 602 to move away from the anti-side slide plate 404. At this time, the gas in the installation sleeve 601 will enter the interior of the fixed cylinder 604 through the connecting air pipe 610, thereby pushing the plug plate 608 to overcome the elastic force of the pushing spring 609 and move toward the connecting air pipe 610. At this time, after the plug plate 608 moves into the interior of the expansion groove 605, the gas will be discharged from the interior of the expansion groove 605 to the outside of the installation sleeve 601, thereby avoiding the increase of the internal air pressure of the installation sleeve 601, and further avoiding the desoldering of the installation box 2.
