[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] When hot-dip galvanizing a metal tubular workpiece, it is necessary to hang it on a hanger and put it into a hot-dip galvanizing tank for hot-dip galvanizing. However, when using the current hot-dip galvanizing hangers, most of them use iron chains to wrap and fix the workpiece, which may cause the part of the workpiece that is wrapped to be blocked by the wrapping and not complete the hot-dip galvanizing process. At the same time, when replacing the tubular workpiece that has been hot-dip galvanized, it is still necessary to re-wrap the unfinished workpiece with the iron chain, which is relatively cumbersome. The following describes a hot-dip galvanizing hanger provided by some embodiments of the utility model in conjunction with the accompanying drawings.

[0023] Embodiment 1:

[0024] In order to ensure the hot-dip galvanizing effect on the outer surface of the tubular workpiece, combined with Figure 1 , Figure 2 and Figure 3 As shown, a hot-dip galvanizing hanger is proposed, which is used to perform hot-dip galvanizing on a workpiece through a hot-dip galvanizing water tank 1. A supporting mechanism 2 is provided on the top of the hot-dip galvanizing water tank 1, and the position of a fixing mechanism 3 is connected and fixed by the supporting mechanism 2. A fixing mechanism 3 is provided on the supporting mechanism 2, and the fixing mechanism 3 is used to fix the tubular workpiece, and at the same time, the hot-dip galvanizing area required on the outer surface of the tubular workpiece is not blocked.

[0025] In order to enable the device to fix the tubular workpiece without blocking the hot-dip galvanizing area on the outer surface of the tubular workpiece, a fixing mechanism 3 is proposed, which is provided with a fixing box 301, a fixing plate 202 is located in the through hole 203 and is rotatably connected to a gear a302 and a gear b303 respectively, the gear a302 and the gear b303 are meshed with each other, and one side of the gear a302 and the gear b303 are fixedly connected to a winding wheel, an electric telescopic rod 304 is installed at the bottom of the fixing box 301, and the movable end of the electric telescopic rod 304 is fixedly connected to a connecting column, and two symmetrical connecting frames 305 are fixedly connected to the connecting column, and the two connecting frames 305 are rotatably connected to special-shaped rods 306, and the bottom ends of the two special-shaped rods 306 are installed with fixed spheres 307 with textured surfaces, and the two connecting frames 305 are provided with adjustment components 308 suitable for tubular workpieces of different specifications, and the two special-shaped rods 306 are fixedly connected to the bottom ends of the two special-shaped rods 306. A hanging ring is installed at the top of the special-shaped rod 306, and traction ropes are connected to the two hanging rings. One end of the two traction ropes is connected to the two winding wheels respectively. A servo motor for driving the gear b303 is installed on one side of the fixed plate 202. The servo motor drives the gear b303 to rotate, so that the gear b303 and the gear a302 are meshed and rotated. At this time, the two winding wheels rotate with the gear a302 and the gear b303 respectively, so that the two winding wheels pull the two traction ropes, thereby driving the two special-shaped rods 306 to rotate on the two connecting frames 305, so that the fixed spheres 307 at the bottom ends of the two special-shaped rods 306 support the inner wall of the tubular workpiece outward, thereby fixing the tubular workpiece, and will not cause obstruction to the outer surface area of ​​the device. The height of the tubular workpiece can be easily adjusted through the electric telescopic rod 304, thereby ensuring the hot-dip galvanizing effect of the device.

[0026] In order to ensure the stability of the fixing mechanism 3 during operation, a supporting mechanism 2 is proposed. A fixing plate 202 is provided with a through hole 203. Two supporting columns 201 are installed on the top of the hot-dip galvanized water tank 1. The fixing plate 202 is connected to the tops of the two supporting columns 201. The position of the fixing plate 202 is fixed by the two supporting columns 201, and the positions of the gears a302 and b303 are fixed by the through hole 203.

[0027] Embodiment 2:

[0028] On the basis of Example 1, the technical solution proposed in Example 1 is used to solve the problem that in the prior art, when hot-dip galvanizing is performed on tubular workpieces, the workpieces are mostly fixed by winding them with iron chains, which may easily cause some areas of the workpiece to be blocked by the winding and not complete the hot-dip galvanizing treatment, thereby affecting the hot-dip galvanizing effect of the workpiece. However, when fixing tubular workpieces of different specifications, if the spacing between the two special-shaped rods 306 cannot be adapted thereto, it will cause the problem that different tubular workpieces cannot be fixed.

[0029] In order to enable the device to fix tubular workpieces of different specifications, combined with Figure 1 and Figure 3 as well as Figure 4 As shown, a highly applicable adjustment component 308 is now proposed, wherein a plurality of adjustment holes 3081 are provided on the connecting frame 305, a square hole 3082 is provided on the connecting frame 305 between the plurality of adjustment holes 3081, a round hole is provided on the special-shaped rod 306, a sleeve 3083 is fixedly connected in the round hole, a round plate 3084 is fixedly connected in the sleeve 3083, springs 3085 are fixedly connected on both sides of the round plate 3084, a round slider 3086 is fixedly connected at the other ends of the two springs 3085, an adjustment rod 3087 is fixedly connected on the other sides of the two round sliders 3086, and two adjustment rods 3087 are fixedly connected on the other sides of the two round sliders 3086. A circular baffle 3088 is fixedly connected to the other side opposite to the rod 3087. By pressing the circular baffle 3088 on both sides of the connecting frame 305, the two circular sliders 3086 squeeze the two springs 3085 respectively and slide inside the sleeve 3083. When the two adjusting rods 3087 are both located in the adjusting hole 3081 area, the special-shaped rod 306 is moved at this time, so that the two adjusting rods 3087 pass through the square hole 3082 on one side thereof and enter the next adjusting hole 3081 in the machine, thereby changing the spacing between the two special-shaped rods 306 to adapt to tubular workpieces of different specifications, thereby greatly improving the applicability of the device.

[0030] The diameter of the two circular sliders 3086 is the same as the inner diameter of the sleeve 3083, so that the two circular sliders 3086 can slide on the inner wall of the sleeve 3083. The diameter of the adjusting rod 3087 is the same as the height of the square hole 3082, so that the special-shaped rod 306 can be moved from one adjusting hole 3081 to the square hole 3082 and then to the next adjusting hole 3081 through the two adjusting rods 3087. The diameter of the circular baffle 3088 is larger than the diameter of the adjusting hole 3081, so that the adjusting component 308 will not fall off from the connecting frame 305.

[0031] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
