By setting the placement plates 301, the two ends of the pipeline to be galvanized can be supported; it is worth noting that by setting the two groups of placement plates 301 at different heights, the pipeline to be galvanized can be in an inclined state during galvanizing, so as to avoid the galvanizing liquid remaining inside the pipeline after the galvanizing is completed, and the placement plate 301 in a low position has a blocking plate for the galvanized pipeline on the surface. The blocking plate is a prior art and is not shown in the figure. It is used to prevent the pipeline from sliding during the galvanizing process.

[0033] Among them, the front and rear ends of the placement plate 301 are rotatably connected to the inner wall of the lifting frame 2 through a hollow tube, so that the placement plate 301 and the pipe to be galvanized follow the lifting frame 2 to enter the interior of the tank body 1 synchronously; the two groups of placement plates 301 are fixedly connected by a connecting rod 302, and by setting the connecting rod 302, the two groups of placement plates 301 can be ensured to move synchronously; multiple groups of limit plates 303 are equidistantly installed on the upper surface of the placement plate 301, and by setting the limit plates 303, the pipe to be galvanized can be limited; it is worth noting that the blocking plate is arranged between two adjacent groups of limit plates 303; a cavity 304 is opened inside the placement plate 301, and the cavity 304 is connected to the opening opened between the multiple groups of limit plates 303; it is worth noting that the components included in the lifting frame 2 and the support frame 3 are specially treated, that is, through surface coating, oxidation, passivation and other treatment methods, a protective film layer can be formed on the surface of the lifting frame 2 and the support frame 3 to prevent corrosion and galvanizing of zinc liquid.

[0034] Combined with Figure 1 -Attached Figure 7, by setting a galvanizing component 4 for completely galvanizing the surface of the pipeline, the surface of the pipeline can be completely galvanized during the galvanizing process, thereby ensuring the galvanizing effect of the pipeline; the galvanizing component 4 includes a first round rod 401 symmetrically inserted on one side of the lifting frame 2, and one end of the first round rod 401 is between the lifting frame 2 and the support frame 3, and the other end of the first round rod 401 is in contact with the surface of the extrusion surface 101 in the initial state. By setting the first round rod 401, it can slide with the extrusion surface 101 and can realize the extrusion of the first round rod 401. One end of the first round rod 401 is movably connected to the second round rod 402 through a connecting piece, and one end of the second round rod 402 is inserted in the interior of the cavity 304. By setting the second round rod 402, it can follow the first round rod 401 to move synchronously when the first round rod 401 moves laterally;

[0035] Among them, combined with Figure 5 The connecting piece includes two groups of limiting grooves 4021 symmetrically opened on the inner wall of the second round rod 402. The limiting grooves 4021 are arc-shaped structures and can play the role of limiting and guiding; the inner walls of the two groups of limiting grooves 4021 are slidably matched with sliding rods 4022, and the sliding rods 4022 are in the middle position of the limiting grooves 4021 in the initial state, and the opposite ends of the two groups of sliding rods 4022 are fixedly connected with mounting seats 4023, and the mounting seat 4023 is fixedly installed at one end of the first round rod 401. By setting the sliding rod 4022 and the mounting seat 4023, it can play a connecting role, so that the second round rod 402 and the first round rod 401 can be movably connected.

[0036] Among them, one end of the second round rod 402 is fixedly connected to a mounting plate 403, and the lower end of the mounting plate 403 is slidably matched with the bottom surface of the cavity 304. The mounting plate 403 is elastically connected to the inner wall of the cavity 304 through a connecting spring, and the connecting spring is sleeved on the surface of the second round rod 402. By setting the mounting plate 403 and the connecting spring, when the second round rod 402 moves, it can synchronously slide inside the cavity 304 and stretch the connecting spring, so that the connecting spring generates a reaction force to facilitate the subsequent resetting of the mounting plate 403; a tooth plate 404 is fixedly installed on one side of the mounting plate 403. By setting the tooth plate 404, it can synchronously move with the mounting plate 403 to play a driving role;

[0037] Among them, the surface of the tooth plate 404 is meshedly connected with multiple groups of equidistantly arranged gears 405, and a rotating wheel 406 is fixedly installed on one side of the multiple groups of gears 405 close to the center position of the trough body 1. One side of the rotating wheel 406 is rotatably connected to the inner wall of the cavity 304, and part of the rotating wheel 406 penetrates through the through opening and extends between the two groups of limit plates 303. By arranging the gear 405 and the rotating wheel 406, the gear 405 can rotate under the action of the moving tooth plate 404 and drive the rotating wheel 406 to rotate synchronously, thereby driving the pipe in contact with the surface of the rotating wheel 406 to rotate, ensuring that the surface of the pipe can be completely galvanized.

[0038] Combined with Figure 1 -Attached Figure 8 , and also includes a slag removal component 5 for shaking the galvanized pipe, so that the slag generated by the pipe during the galvanizing process can be separated from the pipe, ensuring the galvanizing effect of the pipe; the slag removal component 5 includes an extrusion block 501, and the extrusion block 501 is fixedly installed on the side of the tooth plate 404 away from the center of the tank body 1, and by setting the extrusion block 501, it can move synchronously with the tooth plate 404; it is worth mentioning that the extrusion block 501 is a trapezoidal structure, and the inclined surface of the extrusion block 501 faces the moving direction of the tooth plate 404; a driven rod 502 is provided on one side of the extrusion block 501, and the driven rod 502 penetrates the hollow tube and extends to the inside of the slot 203. By setting the driven rod 502, it can move under the extrusion of the extrusion block 501 and extend from the inside of the tank body 1;

[0039] Among them, two groups of limit strips 5021 are symmetrically installed on the surface of the driven rod 502, and the limit strips 5021 are slidably matched with the inner wall of the hollow tube. By setting the limit strips 5021, the driven rod 502 can be limited and guided; the end of the driven rod 502 close to the extrusion block 501 is rotatably connected to the rotating head 503, and the rotating head 503 is set to contact the surface of the extrusion block 501, so as to reduce the friction between the driven rod 502 and the extrusion block 501; the other end of the driven rod 502 is fixedly installed with a matching disk 504, and the matching disk 504 is initially in a In the state, it is arranged inside the receiving groove 204, and the matching disk 504 is rotatably connected to the inner wall of the slot 203 through a return spring. By setting the matching disk 504, it can be extended synchronously with the action of the driven rod 502, enter the inside of the recess 103 and form an extrusion fit with the block 104, so that the support frame 3 can drive the galvanized pipe to swing left and right, so that the plating slag generated in the galvanizing process of the pipe can be separated from the pipe, thereby ensuring the galvanizing effect; it is worth noting that the components contained in the galvanizing component 4 and the slag removal component 5 have also been specially treated and will not be galvanized.

[0040] Specifically, when galvanizing the pipe, the pipe to be galvanized is placed between two sets of adjacent limit plates 303 in sequence and contacts the surface of the rotating wheel 406 to prevent the pipe from being galvanized. After the pipe is galvanized, the lifting frame 2 is driven by the control rope to start sinking into the tank 1, so that the pipe starts to enter the zinc liquid for galvanizing.

[0041] When the lifting frame 2 starts to sink into the tank body 1, the first round rod 401 starts to be squeezed with the extrusion surface 101, and then the second round rod 402 is synchronously pushed to move into the connecting rod 302, and the tooth plate 404 drives the gear 405 to start rotating through the mounting plate 403, so that the rotating wheel 406 starts to drive the pipe in contact with its surface to rotate between the two sets of limit plates 303, so that the pipe can be uniformly galvanized; when the first round rod 401 moves from the extrusion surface 101 to the position of the straight surface 102, the tooth plate 404 drives the gear 405 to start rotating. 4 will no longer move, and at the same time, it will drive the extrusion block 501 to squeeze the driven rod 502 out of the storage groove 204, so that the matching plate 504 enters the inside of the notch 103, and as the lifting frame 2 continues to descend, the matching plate 504 will begin to intermittently contact and squeeze with the staggered block 104, so that the matching plate 504 starts to rotate, and drives the placement plate 301 to rotate synchronously through the limit bar 5021, and the galvanized pipe starts to shake, and the plating slag generated during the galvanizing process of the pipe is separated to ensure the galvanizing effect of the pipe. It is worth noting that when the placement plate 301 swings left and right, it will drive the second round rod 402 to swing synchronously, and the second round rod 402 will not separate from the first round rod 401 under the cooperation of the limit groove 4021, the slide bar 4022 and the mounting seat 4023, and will not be affected by the first round rod 401 and cannot rotate.
