[0002] Zinc is the fourth most common metal, after iron, aluminum and copper. In engineering, it is often used to form active structural coatings that are stronger than iron and have excellent resistance to environmental corrosion, so as to protect steel-based materials.

[0003] Compared with the electro-galvanized coating of about 10μm, the hot-dip galvanized coating is stable and controllable, and its thickness can be as high as more than 100μm, so it is widely used in coating of steel structures.

DETAILED DESCRIPTION

[0023] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0024] The hot-dip galvanized grid steel pipe induction heating device according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0025] like Figure 1-3As shown, the hot-dip galvanized grid steel pipe induction heating device of the embodiment of the utility model includes a support mechanism 10, a feeding assembly 20 and an induction heating assembly 30.

[0026] The supporting mechanism 10 includes a fixing frame 101 and a baffle 102 .

[0027] There are two groups of baffles 102 , and the two groups of baffles 102 are respectively arranged on the top wall of the fixing frame 101 .

[0028] It should be noted that the baffle 102 is fixedly mounted on the top wall of the fixing frame 101 , and the hot-dip galvanized grid steel pipe is transported on the top wall of the fixing frame 101 . During the transportation process, the baffle 102 is used to limit the grid steel pipe.

[0029] The feeding assembly 20 is disposed on the fixing frame 101 , and the feeding assembly 20 includes a feeding bracket 201 and a conveying mechanism 202 .

[0030] The feeding bracket 201 is arranged on the fixing bracket 101 , and the conveying mechanism 202 is arranged on the feeding bracket 201 .

[0031] It should be noted that when the grid steel pipe is transported to the top wall of the feeding bracket 201, the operator manually controls the conveying mechanism 202, and the conveying mechanism 202 drives the grid steel pipe to change from lateral movement to longitudinal movement.

[0032] There are two groups of induction heating components 30 , which are respectively arranged on both sides of the feeding bracket 201 . The induction heating components 30 include an induction box 301 , a driving component 302 , a filtering mechanism 303 and a heating coil 304 .

[0033] The induction box 301 is arranged on the feeding bracket 201 , the driving component 302 is arranged on the induction box 301 , the filtering mechanism 303 is detachably arranged on the induction box 301 , and the heating coil 304 is arranged on the induction box 301 .

[0034] It should be noted that the driving component 302 is an air pump, which is operated by connecting the driving component 302 to the power supply through the control switch. The driving component 302 absorbs the gas generated when the heating coil 304 heats the head end of the grid steel pipe, and the gas is filtered through the filtering mechanism 303.

[0035] Specifically, both ends of the hot-dip galvanized grid steel pipe are heated to facilitate subsequent welding. The grid steel pipe is transported horizontally on the top of the fixed frame 101, and the baffle 102 is used to limit the grid steel pipe during the transportation process. When one end of the grid steel pipe is heated, the operator rotates the conveying mechanism 202, and the conveying mechanism 202 drives the grid steel pipe to move on the feeding bracket 201. During the movement, it penetrates into the induction heating component 30, and the end face of the grid steel pipe penetrates into the heating coil 304. The end face of the grid steel pipe is heated to vaporize and evaporate the zinc layer at the end of the steel pipe. Then the other end face of the grid steel pipe is heated. The two ends of the grid steel pipe are quickly heated to vaporize and evaporate the zinc layer on the end face of the grid steel pipe without affecting subsequent welding.

[0036] In one embodiment of the present invention, Figure 2 The conveying mechanism 202 shown includes a rotating handle 2021, a driving sprocket 2022, a driven shaft 2023, a rotating disc 2024 and a lifting bracket 2025.

[0037] Among them, the rotating handle 2021 is rotatably set on the feeding bracket 201, the driving sprocket 2022 is set on the rotating handle 2021, the driven shaft 2023 is rotatably set on the feeding bracket 201, the rotating disc 2024 is set on the driven shaft 2023, and the ejecting bracket 2025 is set on the rotating disc 2024.

[0038] It should be noted that, in the embodiment described, a driven sprocket is provided on the driven shaft 2023, and a transmission chain is provided on the driving sprocket 2022 and the driven sprocket, so that when the rotating handle 2021 is rotated, the rotating disk 2024 and the top material bracket 2025 are turned over, thereby pushing the movement to the feeding bracket 201 and probing into the heating coil 304 to heat the end face of the grid steel pipe.

[0039] In one embodiment of the present invention, Figure 3 The filter mechanism 303 shown includes an outer cover shell 3031 , a filter component 3032 , a first adsorption component 3033 , a second adsorption component 3034 and a third adsorption component 3035 .

[0040] The outer cover shell 3031 is detachably arranged on the induction box 301 , the filter component 3032 is arranged in the outer cover shell 3031 , and the first adsorption component 3033 , the second adsorption component 3034 and the third adsorption component 3035 are arranged in the outer cover shell 3031 in sequence.

[0041] It should be noted that the outer cover shell 3031 is limitedly installed on the induction box 301 for easy disassembly. The filter component 3032 effectively filters the gas. The first adsorption component 3033, the second adsorption component 3034 and the third adsorption component 3035 are adsorption cotton nets. When the gas passes through the three groups of adsorption cotton nets, the gas is effectively adsorbed and filtered.

[0042] In one embodiment of the present invention, Figure 1 The feeding bracket 201 shown is provided with multiple groups of transverse conveying rollers, and the rotating disc 2024 is arranged between two adjacent groups of transverse conveying rollers.

[0043] It should be noted that the grid steel pipe is transported on the feeding bracket 201 through the transverse conveying rollers. When the operator drives the rotating disc 2024 to rotate by rotating the handle 2021, the rotation of the rotating disc 2024 drives the top material bracket 2025 to rotate from between the two transverse conveying rollers, and drives the grid steel pipe to move into the heating coil 304.

[0044] In one embodiment of the present invention, Figure 2 The lifting bracket 2025 shown is a semicircular bracket, and the inner wall of the lifting bracket 2025 is attached with a plastic pad with anti-slip patterns.

[0045] It should be noted that the top material support 2025 is rotatably fitted to the bottom wall of the grid steel pipe, and the grid steel pipe is driven to move through the anti-skid plastic pad.

[0046] In one embodiment of the present invention, Figure 3 As shown, the mesh apertures of the first adsorption component 3033 , the second adsorption component 3034 and the third adsorption component 3035 become smaller in sequence.

[0047] It should be noted that the mesh holes on the first adsorption component 3033, the second adsorption component 3034 and the third adsorption component 3035 have different apertures. When the gas is inhaled, it is adsorbed and filtered layer by layer, so that the exhaust gas reduces the emission of harmful substances.

[0048] The steps of induction heating of hot-dip galvanized mesh steel pipes of the utility model are as follows: the mesh steel pipes are transported horizontally on the top of the fixed frame 101, and the mesh steel pipes are limited by the baffle 102 during the transportation process. When one end of the mesh steel pipe is heated, the operator rotates the conveying mechanism 202, and the conveying mechanism 202 drives the mesh steel pipe to move on the feeding bracket 201, and the mesh steel pipe is inserted into the induction heating component 30 during the movement. When the rotating handle 2021 rotates, the rotating disc 2024 and the top material bracket 2025 are turned over, thereby pushing the movement to the feeding bracket 201 and inserting into the heating coil 304 to heat the end face of the mesh steel pipe.

[0049] One end of the steel pipe is inserted into the heating coil 304 to heat the end of the steel pipe and vaporize the zinc layer on the end of the steel pipe. Then the other end of the steel pipe is heated. The two ends of the steel pipe are quickly heated to vaporize the zinc layer on the end of the steel pipe without affecting the subsequent welding.

[0050] In summary, the hot-dip galvanized mesh steel pipe induction heating device of the utility model embodiment has the mesh steel pipe limited conveying, and the mesh steel pipe in conveying is controlled by the operator to probe into the heating coil, and the end of the hot-dip galvanized steel pipe is placed in the matching induction coil, and the zinc layer at the end of the steel pipe is efficiently vaporized and evaporated after time-controlled heating, which reduces labor intensity and effectively improves construction efficiency.

Ordinary technicians in this field can change, modify, replace and deform the above embodiments within the scope of the present invention.
