[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The galvanized pipe segmented hot-dip galvanizing device provides two technical solutions:

[0025] like Figure 1 and 2 The first embodiment is shown: comprising a support frame 1, a mobile hoisting mechanism 2, a galvanizing pool 3 and a cooling pool 4. The galvanizing pool 3 and the cooling pool 4 are placed below the support frame 1. The mobile hoisting mechanism 2 is mounted on the support frame 1 for hoisting the galvanized pipe. A scraping mechanism is provided on the galvanizing pool 3. The scraping mechanism comprises:

[0026] The segmented scraping assembly 5 includes two left and right L-shaped plates 51. The tops of the two L-shaped plates 51 are each provided with two front and rear through slots 53. The positions of the through slots 53 are aligned with the positions of the lifting cables on the mobile lifting mechanism 2. Three scrapers 52 are slidably connected to the opposite sides of the two L-shaped plates 51 through the cooperation of T-shaped blocks and T-shaped slots.

[0027] The driving assembly 6 is arranged on the front and back of the galvanizing pool 3 to drive the two L-shaped plates 51 to move. The driving assembly 6 includes two groups of front and rear mounting seats 61. The two groups of mounting seats 61 are fixedly connected to the front and back of the galvanizing pool 3 respectively. A bidirectional threaded rod 62 is rotatably connected between each group of mounting seats 61. The left and right L-shaped plates 51 are respectively threadedly connected to the left and right sides of the surfaces of the two bidirectional threaded rods 62. The front and back of the galvanizing pool 3 are fixedly connected to driving motors 63. The output ends of the two driving motors 63 are fixedly connected to driving gears 64. The surfaces of the two bidirectional threaded rods 62 are fixedly connected to driven gears 65. The driving gear 64 and the driven gear 65 are meshed for transmission.

[0028] The adjustment component 7 is arranged on the outside of the three L-shaped plates 51 and is used to control the depth of the L-shaped plates 51 entering the zinc liquid. The adjustment component 7 includes a baffle 71, which is fixedly connected to the right side of the scraper 52. The top of the L-shaped plate 51 is fixedly connected to an adjustment motor 72, and the output end of the adjustment motor 72 is fixedly connected to an eccentric wheel 73, and the eccentric wheel 73 is in contact with the baffle 71. An infrared sensor 74 is installed on the left side of the scraper 52 through the installation component 8. The infrared sensor 74 is also provided on the scraper 52 on the left, and is staggered with the infrared sensor 74 on the scraper 52 on the right, and a storage groove for the infrared sensor 74 to enter is provided on the corresponding scraper 52.

[0029] After hot-dip galvanizing is completed, the segmented scraping mechanism is started to scrape off a layer of solid zinc produced on the surface of the galvanizing pool without manual operation. At the same time, the depth of the scraper 52 entering the liquid of the galvanizing pool 3 is adjusted by adjusting the component 7 to avoid large liquid surface shaking that affects the galvanizing effect, thereby improving the degree of automation during use of the device.

[0030] like Figure 2 and 3 The second embodiment is shown, and the main difference from the first embodiment is that: the mounting assembly 8 includes an L-shaped frame 81, and the L-shaped frame 81 is fixedly connected to the left side of the scraper 52, and the front and back sides of the L-shaped frame 81 are slidably connected with T-shaped rods 82, and the two T-shaped rods 82 pass through the L-shaped frame 81 and extend to the inside of the L-shaped frame 81. One end of the two T-shaped rods 82 located inside the L-shaped frame 81 is fixedly connected to a pressure plate 83, and a limit spring 84 is provided on the surface of the T-shaped rod 82 located between the pressure plate 83 and the L-shaped frame 81.

[0031] The infrared sensor 74 is mounted on the scraper 52 via the mounting assembly 8, so that the infrared sensor 74 can be easily disassembled and replaced when damaged, thereby improving the convenience of using the device.

[0032] When in use, the pipe is placed in the galvanizing pool 3 through the lifting of the mobile lifting mechanism 2, and the driving motor 63 is started to rotate the driving gear 64, and the driving gear 64 rotates to transmit the transmission to the driven gear 65, and the driven gear 65 rotates and causes the two-way threaded rod 62 to rotate, and the two-way threaded rod 62 rotates to make the two L-shaped plates 51 approach each other, and the two L-shaped plates 51 move and make the two opposite scrapers 52 close to each other. After the hot dip time is up, the driving motor 63 is started again to make the two-way threaded rod 62 rotate in the opposite direction, so that the two L-shaped plates 51 move in the opposite direction, and at the same time, the red The external sensor 74 detects the liquid level and starts the adjustment motor 72 to rotate the eccentric wheel 73. The rotation of the eccentric wheel 73 adjusts the depth of the scraper 52 entering the liquid surface. When the relative scrapers 52 move away from each other, the solidified zinc layer on the surface of the zinc liquid is scraped off. In addition, when installing the infrared sensor 74, the infrared sensor 74 is placed between the two pressure plates 83. When placing, the two pressure plates 83 are moved away from each other. After the pressure plate 83 enters the inside, the pressure plate 83 is pressed against the outside of the infrared sensor 74 under the action of the limit spring 84, thereby fixing the infrared sensor 74.
