Technical Field
[0001] The utility model relates to the technical field of galvanized sheets, and particularly relates to a hanging rack for galvanizing galvanized sheets. Background Technique
[0002] A galvanized sheet refers to a steel sheet with a layer of zinc plated on its surface. By plating a layer of zinc on the surface of the steel sheet, the corrosion resistance of the steel sheet can be effectively improved, and its service life is greatly increased.
[0003] During the galvanizing process of steel sheets, in order to avoid collisions between multiple steel sheets in the electroplating solution, the hanging method is often used, and a hanging rack is required. Some existing hanging racks often fix the steel sheets by clamping. Although the connection between the steel sheet and the hanging rack is firm, after being immersed in the electroplating solution, since the clamping plate clamps the steel sheet, the contact surface between the clamping plate and the steel sheet (the weight of the steel sheet is large, and in order to improve the clamping stability, the contact surface between the clamping plate and the steel sheet is large) cannot fully contact the electroplating solution, so this part of the surface cannot be galvanized, which may lead to uneven galvanized layers, inconsistent thickness, and even possible ungalvanized areas.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model
[0021] Please refer to Figures 1-4 , the present utility model discloses a hanging rack for galvanized steel plates during galvanizing, including an upper U-shaped plate 10 and a lower U-shaped plate 20. Both the upper U-shaped plate 10 and the lower U-shaped plate 20 are perforated plates. A telescopic rod 30 is welded to the top of the upper U-shaped plate 10, and a hanging ring 40 is welded to the top surface of the telescopic rod 30. A pair of lugs 50 are welded to the front and rear inner walls of the upper U-shaped plate 10 and the lower U-shaped plate 20. Among them, four lugs 50 on the lower side are welded with four convex rods 60 on the top surface. Each convex rod 60 correspondingly penetrates the upper lug 50, and the upper lug 50 and the convex rod 60 can slide up and down, so that the lower U-shaped plate 20 has the function of moving up and down, and can cooperate with the support mechanism 80 to adjust the distance between the upper U-shaped plate 10 and the lower U-shaped plate 20, and can be applicable to galvanized steel plates of different sizes. A plurality of round holes 70 distributed up and down are opened on the front surface of the convex rod 60, and a support mechanism 80 is inserted on each pair of convex rods 60
[0022] Specifically, the support mechanism 80 includes an insertion rod 81. The insertion rod 81 penetrates through a pair of round holes 70 in the front and rear. An arc-shaped retaining piece 82 is welded to the front surface of the insertion rod 81. The arc-shaped retaining piece 82 fits on the surface of the front convex rod 60. The length of the insertion rod 81 is twice the distance between the front and rear convex rods 60. The inside of the convex rod 60 is filled with magnetic powder, and the arc-shaped retaining piece 82 is a magnet
[0023] In this embodiment, the insertion rod 81 is attached to the top surface of the upper U-shaped plate 10. Since the insertion rod 81 passes through the round hole 70 on the convex rod 60, and the lower U-shaped plate 20 is indirectly fixedly connected to the convex rod 60 through the convex piece 50, the support for the lower U-shaped plate 20 can be realized, so that the distance between the upper U-shaped plate 10 and the lower U-shaped plate 20 can be adjusted.
[0024] Specifically, the telescopic rod 30 includes a sleeve 31 welded to the middle of the top surface of the upper U-shaped plate 10. A sliding rod 32 is slidably connected to the sleeve 31 up and down. The top of the sliding rod 32 is fixedly connected to the bottom of the hanging ring 40. A plurality of first connection holes 33 are arranged vertically on the front surface of the sliding rod 32. A first fastening bolt 34 is threadedly connected to the front surface of the sleeve 31, and the first fastening bolt 34 is inserted into one of the first connection holes 33.
[0025] In this embodiment, it has the function of length adjustment, can adjust the distance between the steel plate to be galvanized and the hanging ring 40, and can meet different actual needs.
[0026] Specifically, the hanging ring 40 includes a first arc piece 41 welded to the top of the sliding rod 32. A pair of arc-shaped slots 42 are arranged on the top surface of the first arc piece 41. A second arc piece 43 is slidably connected to one of the arc-shaped slots 42. The second arc piece 43 is inserted into the other arc-shaped slot 42. A second fastening bolt 44 is threadedly connected to the top surface of the second arc piece 43. A second connection hole is arranged on the lower inner wall of one of the arc-shaped slots 42. The bottom end of the second fastening bolt 44 is inserted into the second connection hole. A long hole 45 is arranged on one side of the first arc piece 41. The long hole 45 communicates with one of the arc-shaped slots 42. The front-back length of the long hole 45 is smaller than the front-back length of the arc-shaped slot 42. The second fastening bolt 44 passes through the long hole 45.
[0027] In this embodiment, it can be directly hung on the hook. When it is necessary to directly put the hanging ring 40 on the long rod, at this time, the second arc piece 43 is not inserted into the other arc-shaped slot 42. At this time, there will be a notch at the top of the hanging ring 40, which can pass through the long rod from bottom to top, and then slide the second arc piece 43 to make it inserted into the other arc-shaped slot 42 until it cannot slide anymore. Then rotate the second fastening bolt 44 clockwise so that the bottom end of the second fastening bolt 44 is inserted into the second connection hole. There is no need to put it on from one end of the long rod. When there are obstacles at both ends of the long rod, it still does not affect the hanging ring 40 being put on the long rod, and the anti-interference ability is strong.
[0028] Working principle and usage process of the utility model: The normal hanging ring 40 will be hung on the hook or long rod of the lifting equipment. Adjust the distance between the upper U-shaped plate 10 and the lower U-shaped plate 20 according to the size of the galvanized steel plate. Hold the lower U-shaped plate 20 and drive the lower U-shaped plate 20 to move up or down. After moving to an appropriate height, insert the insertion rod 81 through the round hole 70 closest to the top surface of the upper U-shaped plate 10, and make the arc-shaped baffle 82 magnetically fit on the front surface of the front convex rod 60. Hold the lower U-shaped plate 20 and slowly move it down. At this time, the lower U-shaped plate 20 will move down slightly. When the insertion rod 81 is in close contact with the top surface of the upper U-shaped plate 10, the lower U-shaped plate 20 will not continue to move down. Place the steel plate between the lower U-shaped plate 20 and the upper U-shaped plate 10. At this time, the steel plate is in an inclined placement state. Start the lifting equipment to drive the entire hanging and placing rack to move downwards, so that the steel plate is completely immersed in the electroplating solution to achieve galvanizing. After a period of time, since a part of the steel plate protrudes, the staff can adjust the position of the steel plate through tools (such as a metal rod). The steel plate moves slightly horizontally on the lower U-shaped plate 20 and the upper U-shaped plate 10, so that the galvanizing of the steel plate can be more uniform.
