DETAILED DESCRIPTION

[0019] Example 1

[0020] like Figures 1-4 As shown, a steel hot-dip galvanizing equipment proposed in this embodiment includes a galvanizing box 1, a lifting mechanism and a lifting plate 20. The galvanizing box 1 has a galvanizing chamber 101, and a galvanizing component slides inside the galvanizing box 1. The galvanizing box 1 is provided with a filter 6, a fan, a side door 5 and a support component. When the equipment is in use, the fan and the filter 6 ensure the circulation of air inside the galvanizing box 1, so that the galvanized surface of the steel can be cooled as quickly as possible to facilitate subsequent processing by the user; the lifting mechanism is arranged on the galvanizing box 1, and a plurality of hooks are connected to the output end of the lifting mechanism; the lifting plate 20 has a double-slope top 201, a plurality of pull ring portions 202 are arranged at the top of the double-slope top 201, and a plurality of bottom ring portions 203 are arranged at the bottom of the double-slope top 201. A hook 21 is provided on each of the multiple bottom ring portions 203, and the multiple hooks are connected to the multiple pull ring portions 201 in a one-to-one correspondence.

[0021] The support assembly includes a rotating rod 2 rotatably set on the galvanizing box 1, a support frame 3 rotatably set on the rotating rod 2, and an auxiliary rod with both ends rotatably connected to the rotating rod 2 and the support frame 3 respectively. The top of the support frame 3 is in contact with the closed door 4. The user first adjusts the position of the rotating rod 2 and the auxiliary rod so that the auxiliary rod is flush with the ground, and then adjusts the position of the support frame 3 so that the top of the support frame 3 is flush with the ground, and then rotates the closed door 4 onto the support frame 3 to form a platform for the user to place steel, thereby facilitating the user to fix the steel on multiple hooks 21, avoiding contact between the user and the zinc liquid and causing injury to the user.

[0022] When using this embodiment, the user hoists the steel on multiple hooks 21, and then the lifting mechanism first pulls the lifting plate 20 to a height that is convenient for placing the steel into the galvanizing assembly through the pulling hook. The lifting mechanism drives the lifting plate 20 to descend into the zinc liquid in the galvanizing assembly for galvanizing. When taking out the steel, the lifting plate 20 takes out the residue on the surface of the zinc liquid to prevent the residue on the surface of the zinc liquid from adhering to the steel and affecting the galvanizing quality of the steel. When the steel is out of the zinc liquid, the user can hang the steel in the air for a while to cool it, which also facilitates the excess zinc liquid to flow into the galvanizing assembly. During the use of the equipment, external force will destroy the hardened zinc liquid attached to the connection between the lifting mechanism and the lifting plate 20, thereby preventing the zinc liquid from affecting the working efficiency of the lifting mechanism, improving the time interval for users to maintain the equipment, and reducing the user's work intensity.

[0023] Example 2

[0024] like Figure 1-Figure 3 As shown, this embodiment proposes a steel hot-dip galvanizing equipment. Compared with Example 1, in this embodiment, the lifting mechanism includes a motor 16 arranged at the top of the galvanizing box 1, a bevel gear a17 arranged at the output end of the motor 16, two groups of lifting components are arranged on the galvanizing box 1, a driving rod 15 with two ends respectively connected to a group of lifting components, and a bevel gear b18 coaxially arranged on the driving rod 15, and the bevel gear a17 and the bevel gear b18 are meshed and connected.

[0025] The lifting assembly includes a lifting frame 10 arranged on the galvanizing box 1, a winding roller a11 and a winding roller b13 rotatably arranged on the lifting frame 10, a gear a12 coaxially arranged on the winding roller a11, a gear b14 coaxially arranged on the winding roller b13, and a pair of rollers 19 rotatably arranged on the lifting frame 10, the gear b14 is coaxially connected to the drive rod 15, the gear b14 is meshed with the gear a12, the winding roller a11 and the winding roller b13 are both wound with lifting ropes, the lifting ropes are connected to the draw hook, and the roller 19 is in rolling contact with the lifting ropes.

[0026] When the steel is galvanized in this embodiment, the motor 16 drives the bevel gear a17 to rotate, and the bevel gear a17 drives the driving rod 15 to rotate through the bevel gear b18, and the driving rod 15 drives the gear b14 to rotate through the gear a12, so that the winding roller a11 and the winding roller b13 rotate relative to each other or rotate in opposite directions, so that the lifting ropes on the winding roller a11 and the winding roller b13 can synchronously drive the hook to rise and fall. The lifting rope can facilitate the user to move the lifting plate 20 to the closed door 4, thereby reducing the difficulty for the user to fix the steel. The lifting rope can be made of steel rope or other materials.

[0027] Example 3

[0028] like Figure 2 and Figure 4 As shown, this embodiment proposes a steel hot-dip galvanizing equipment. Compared with Example 1, in this embodiment, the galvanizing component includes a temperature control frame 7, a heating plate 8 arranged on the temperature control frame 7, a liquid storage tank 9 slidably arranged on the temperature control frame 7, and a moving component arranged at the bottom end of the temperature control frame 7, and the moving component is in rolling contact with the bottom end of the galvanizing chamber 101.

[0029] A temperature control cavity is formed between the temperature control rack 7 and the liquid storage tank 9. The temperature control rack 7 includes a temperature control rack main body 71 and a plurality of limit block parts 72 arranged on the temperature control rack main body 71. The plurality of limit block parts 72 are all located in the temperature control cavity. The temperature control rack main body 71 has a temperature control channel 711, which is connected to the temperature control cavity.

[0030] When heating zinc in this embodiment, the user melts the zinc inside the liquid reservoir 9 through the heating plate 8, and at the same time, the user sends hot air sufficient to melt the zinc into the temperature adjustment channel 711, so that the hot air cooperates with the heating plate 8 to melt the zinc inside the liquid reservoir 9, thereby increasing the melting speed of the zinc and avoiding the user being injured by contact with the zinc when sending the melted zinc to the liquid reservoir 9. When the user needs to cool the zinc, the user can send cold water to the temperature adjustment channel 711 and the inside of the temperature adjustment chamber to quickly harden the part of the zinc that is in contact with the liquid reservoir 9, making it easier for the user to take the zinc out of the liquid reservoir 9.

[0031] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
