Description

Technical Field

[0001] This utility model relates to the technical field of galvanized steel pipe processing equipment, specifically a hot-dip galvanized steel pipe hanger. Background Technology

[0002] Galvanized steel pipe uses high-quality steel pipe as the base material and forms a uniform and dense zinc alloy protective layer on the surface through a hot-dip galvanizing process. This significantly improves its corrosion resistance and effectively resists erosion from harsh environments such as humidity and acids and alkalis, extending its service life several times over that of ordinary steel pipes. This pipe combines the high strength and rigidity of steel pipes with the self-healing properties of the zinc layer. It can withstand high-pressure transportation requirements and can be easily installed through welding, threaded connections, and other methods. It is widely used in construction scaffolding, fire-fighting water supply, municipal pipe networks, industrial fluid transportation, and transportation facilities.

[0003] In existing galvanized steel pipe production processes, clamps are typically used to hold the steel pipes before immersing them in molten zinc for hot-dip galvanizing. However, the areas where the clamps contact the steel pipe cannot fully contact the molten zinc, leading to incomplete galvanizing and poor coating uniformity, which severely affects product quality. To achieve better hot-dip galvanizing of steel pipes and improve coating uniformity, this application proposes a hot-dip galvanizing steel pipe hanger. Utility Model Content

[0004] The purpose of this utility model is to provide a hot-dip galvanized steel pipe hanger to solve the problem that the part of the existing clamp that contacts the steel pipe cannot fully contact the high-temperature zinc liquid, resulting in incomplete galvanizing and poor coating uniformity.

The electric guide rail component includes an electric linear guide rail. Two electric sliders are symmetrically slidably connected to the bottom ends of the electric linear guide rail. The electric linear guide rail is fixedly connected to the lower surface of the lifting plate.

[0008] The two movable fixing frames include a slider connecting plate. Two mounting rods are symmetrically fixedly connected to both ends of the lower surface of the slider connecting plate.

By setting the outer top inclined surface 704 and the inner top inclined surface 804, it is possible to contact the outer and inner rings of steel pipes of different diameters, which facilitates the clamping of steel pipes of different diameters and improves the applicability of the equipment.

[0015] The hydraulic lifting frame 1 includes a lifting plate 101. Two lifting hydraulic cylinders 102 are symmetrically fixedly connected to both ends of the lower surface of the lifting plate 101. By setting two lifting hydraulic cylinders 102, it is easy to drive the steel pipe at the bottom of the lifting plate 101 to lift and lower for hot-dip galvanizing.

[0016] The tops of the two motor drive wheels 2 are fixedly connected to the bottoms of the two lifting hydraulic cylinders 102 respectively. The electric guide rail component 3 includes an electric linear guide rail 301. Two electric sliders 302 are symmetrically slidably connected at both ends of the bottom of the electric linear guide rail 301.

[0017] Among them, the two movable fixed frames 4 include a slider connecting plate 401. Two mounting rods 402 are symmetrically fixedly connected to both ends of the lower surface of the slider connecting plate 401. The upper surface of the slider connecting plate 401 is fixedly connected to the electric slider 302. The bottom of the two mounting rods 402 is fixedly connected to a mounting plate 403. Two outer sliding grooves 404 are symmetrically arranged at both ends of the mounting plate 403. Two inner sliding grooves 405 are symmetrically arranged on one side of the two outer sliding grooves 404. By setting two outer sliding grooves 404 and two inner sliding grooves 405, the outer hydraulic cylinder 502 and the inner hydraulic cylinder 602 can stably drive the outer ring mounting plate 501 and the inner ring mounting plate 601 to move, thereby making the outer top ring component 7 and the inner top ring component 8 more stably press against the steel pipe.

[0020] Working principle: When the two motor drive wheels 2 are energized, they move the hydraulic lifting frame 1 to a designated position. The electric linear guide rail 301 moves the two electric sliders 302 closer together, which in turn moves the two movable fixed frames 4 closer together. This further moves the multiple inner top ring components 8 on the two movable fixed frames 4 to press against the inner rings at both ends of the steel pipe. The motor drive wheels 2 move the hydraulic lifting frame 1 above the container containing high-temperature zinc liquid. The two lifting hydraulic cylinders 102 move the lifting plate 101 down, thereby immersing the bottom steel pipe into the high-temperature zinc liquid for hot dipping. After a period of processing, the two outer hydraulic cylinders 502 drive the outer ring mounting plate 501 to move along the outer slide groove 404, thereby driving the outer top ring components 7 on the two outer ring mounting plates 501 at both ends to move closer to each other, so that the two outer top blocks 703 at both ends press against the outer rings at both ends of the steel pipe through the outer top inclined surface 704. The two inner hydraulic cylinders 602 drive the inner ring mounting plate 601 to move along the inner slide groove 405, thereby driving the two inner ring mounting plates 601 at both ends to move further apart, so that the two inner top ring components 8 loosen the two ends of the steel pipe and perform a more uniform hot-dip galvanizing process.
