[0002] At present, in the hot-dip galvanizing industry for steel sections, the main process of hot-dip galvanizing for steel sections is to use a feeding mechanism composed of a conveyor chain to move a whole group of steel sections from the feeding position of the zinc pot into the zinc pot through the material-receiving L-hook, which is called receiving the material, and then galvanizing; for example: Chinese patent CN 202011152243.9 is named "A hot-dip galvanizing system and process for steel sections" and CN202022393895.3 is named "A material-receiving L-hook device for a hot-dip galvanizing system for steel sections", etc. The zinc pot discharge position uses a magnetic roller or an electromagnetic suction cup to move the whole group of steel sections to the inclined roller conveyor, which is called leading up, for example, Chinese patent CN201320057842.1 is named "Magnetic roller assembly for hot-dip galvanizing production line", etc.; the whole group of steel sections is converted from the inclined roller conveyor to a flat roller conveyor and runs into the air knife treatment room.

The connecting hook group 1 and the connecting hook group 2 are alternately matched with the feeding mechanism 12 and the lifting hook 5, and the whole group of steel sections 13 is brought from the feeding mechanism 12 into the zinc liquid for galvanizing and then sent to the lifting hook 5; the number of the magnetic rollers 8 is multiple , arranged in a row and tilted upward on the magnetic roller frame 16, the magnetic roller frame 16 is connected to the lifting mechanism 21 to control the lifting of the magnetic roller 8, the magnetic roller frame 16 is arranged on the magnetic roller translation walking mechanism 6, and the magnetic roller translation walking mechanism 6 is arranged on the magnetic roller translation track 10; the front end low point of the magnetic roller frame 16 is located on the discharge side of the zinc pot, and the rear end high point of the magnetic roller frame 16 matches the inclined roller 7, which is inclined upward to match the inclination angle of a row of magnetic rollers 8; the front end low point of the magnetic roller frame 16 is provided with an air knife 14, and the wind direction of the air knife 14 is toward the zinc pot; after galvanizing on the lifting hook 5, the entire group of steel sections 13 is adsorbed by the magnetic roller 8 and the surface of the entire group of steel sections 13 is cleaned by the air knife 14, and the excess zinc liquid cleaned is blown back to the zinc pot.

[0028] The material hook group 1 includes a material hook 1 and a material hook 3, and the material hook group 2 includes a material hook 2 and a material hook 4. The material hook 1, the material hook 2, the material hook 3 and the material hook 4 are the same structure L hooks.

The shape of the profiling grooves 17 matches the cross-sectional shape of the steel section, and the number of the profiling grooves 17 matches the number of steel sections in the entire group 13 of steel sections.

[0029] The feeding mechanism 12 feeds the whole group of steel sections 13 arranged at a fixed interval into the galvanizing machine. The feeding mechanism 12 is located between the receiving hook groups. The receiving hook groups rise, and the whole group of steel sections 13 falls into the receiving hook groups and separates from the feeding mechanism 12. After the galvanizing machine uses two sets of receiving hook groups to alternately take away the whole group of steel sections 13, the feeding mechanism 12 withdraws. After the whole group of steel sections 13 is completely immersed in the zinc liquid, after completing the specified timing according to the galvanizing process requirements, the whole group of steel sections moves to the discharge side at the liquid level, and the lifting hook 5 starts the lifting action. The whole group of steel sections 13 rotates with the rear end as the axis and the front end tilts upward. The lifting hook lifts the whole group of steel sections onto the magnetic roller 8, and the lifting mechanism 21 drives the magnetic roller 8 to rise, lifts the whole group of steel sections 13, completes the blowing process through the wind knife, and is placed on the inclined roller 7 to enter the next process.

[0030] The entire group of steel sections 13 on the feeding mechanism 12 is arranged longitudinally, and the material hook 1 and the material hook 3 of the material hook group 1 are arranged longitudinally front to back. The material hook 1 and the material hook 3 respectively support the front and rear of the entire group of steel sections 13. Through the height coordination of the material hook 1 and the material hook 3, the entire group of steel sections 13 is tilted downward and forward when entering the zinc liquid level of the zinc pot 15 to avoid splashing of the zinc liquid. The entire group of steel sections 13 is adjusted horizontally by the coordination of the material hook 1 and the material hook 3 at the set depth of the zinc liquid; the entire group of steel sections 13 is immersed in the zinc liquid in the zinc pot 15 for galvanizing and then lifted up and sent to the lifting hook 5 on the discharge side. The lifting hook 5 lifts the front end of the entire group of steel sections 13 upward, and the entire group of steel sections 13 is tilted upward by the tilted magnetic The magnetic roller 8 is adsorbed, and the lifting mechanism 21 drives the magnetic roller 8 to rise, lifting the entire group of steel sections 13; at the same time, the wind knife 14 at the low point of the front end of the magnetic roller frame 16 cleans the surface of the entire group of steel sections 13 adsorbed by the magnetic roller 8, and the excess zinc liquid cleaned is directly blown back into the zinc pot; the entire group of steel sections 13 after cleaning is led upward by the magnetic roller 8 to the top of the inclined roller 7, and the magnetic roller 8 is released, and the entire group of steel sections 13 is placed on the inclined roller 7 with a matching inclination; while the material receiving hook group 1 performs the above actions, the material receiving hook 2 2 and the material receiving hook 4 4 of the material receiving hook group 2 receive the next group of steel sections sent by the feeding mechanism 12 on the feeding side, and the work efficiency is improved by alternating material receiving, galvanizing and leading by the material receiving hook group 1 and the material receiving hook group 2.

[0031] The surface of the magnetic roller 8 is provided with a row of profiling grooves 18 , the shape of which matches the cross-sectional shape of the steel section, and the number of which matches the number of steel sections in the entire group of steel sections 13 , so as to facilitate the adsorption of the entire group of steel sections 13 .

[0032] A galvanizing mechanism translation track 11 is located above the zinc pot 15, and a galvanizing mechanism translation travel mechanism 9 is mounted on this track 11. The first and second receiving hook groups, the material lifting hook 5, and corresponding equipment 20 above the zinc pot are all mounted on this galvanizing mechanism translation travel mechanism 9. When the zinc pot requires slag removal or regular inspection, the galvanizing mechanism translation travel mechanism 9 moves the entire actuator assembly along the galvanizing track 11 to the outside of the zinc pot. The magnetic roller translation travel mechanism 6 moves the magnetic roller 8 along the magnetic roller translation track 10 to the outside of the zinc pot, clearing the zinc pot and facilitating slag removal and inspection. After completion of the operation, each mechanism returns to its working position.

[0033] In the embodiment, the steel sections are angle steels. The feeding mechanism 12 feeds a whole set of steel sections 13 arranged at a fixed interval into the feeding side of the galvanizing machine. After the galvanizing machine removes the whole set of steel sections 13 from the feeding mechanism 12 through the material hook 1 and the material hook 3, the feeding mechanism 12 withdraws, and the material hook 1 and the material hook 3 position the whole set of steel sections in the contour groove 17 of the material hook 1 and the material hook 3. The cooperation of the material hook 1 and the material hook 3 makes the whole set of steel sections tilt at a certain angle before entering the zinc liquid, thereby reducing the splashing of zinc liquid caused by the impact of the zinc liquid surface caused by the downward feeding of materials in the industry, and reducing zinc consumption. After the entire set of steel sections 13 is completely immersed in the zinc bath, the connecting hooks 1 and 3 are used to adjust the entire set of steel sections to a horizontal position at a specified depth. After completing the specified sequence according to the galvanizing process requirements, the entire set of steel sections 13 moves to the discharge side at the liquid level. The lifting hook 5 starts the lifting action, and the entire set of steel sections 13 rotates around its rear end as an axis, with its front end tilted upward. The lifting hook lifts the entire set of steel sections onto the magnetic roller 8, where the air knife is used to complete the plating. The air knife is located in the zinc pot area and blows excess zinc liquid directly back into the zinc pot, further reducing zinc consumption. The steel section then passes through the inclined roller 7 and enters the next process.

[0034] While the material receiving hook 1 and the material receiving hook 3 are moving horizontally with the material to the discharge side under the zinc liquid surface, the material receiving hook 2 and the material receiving hook 4 are moving to the inlet side to take the next group of steel materials, and the actions of the material receiving hook 1 and the material receiving hook 3 are repeated. The material receiving hook group 1 and the material receiving hook group 2 are repeated alternately to realize continuous production. The whole process does not require human participation, thereby improving the production environment in the workshop.

[0035] The specific instructions are as follows:

[0036] ①In Figure 3 In the process, the feeding mechanism 12 feeds the whole set of steel sections 13 arranged at a certain interval into the galvanizing machine, and the material receiving hook group 1 is ready to lift the material.

[0037] ②In Figure 4 In the process, after the material receiving hook group 1 completes the material lifting, the feeding mechanism 12 withdraws and prepares for the next group of materials. During the waiting process, the material receiving hook group 1 uses its own cylinder action to limit the steel sections in the profiling grooves of the material receiving hook 1 and the material receiving hook 3, so that the entire group of steel sections 13 will not change the existing arrangement state due to the buoyancy of the zinc liquid; after the material receiving hook group 1 waits for the feeding mechanism to withdraw, the material receiving hook 1 first descends a certain distance, and the material receiving hook 3 does not move, and the entire group of steel sections forms a certain inclination, ready to enter the zinc liquid.

[0038] ③In Figure 5 In the process, the hook group 1 is immersed in the zinc liquid to a specified depth, and the hook 1 and the hook 3 eventually reach the same depth and maintain this depth until the preset process time is reached.

[0039] ④In Figure 6In the process, the receiving hook 1 and the receiving hook 3 move the whole group of steel sections 13 to the discharge side, and at the same time, the receiving hook group 2 moves to the receiving position on the feed side, ready to pick up the next group of steel sections delivered by the feeding mechanism 12. After picking up the materials, the timing action of the receiving hook group 1 is repeated. Figure 7 Yes Figure 6 Front view of the status.

[0040] ⑤In Figure 8 During the operation, the lifting hook 5 lifts the steel 13 upward, and the entire group of steel sections 13 rotates about the receiving hook 1. The receiving hooks 1 and 3 remain stationary, and the entire group of steel sections 13 is magnetically attracted to the magnetic roller 8. The magnetic roller 8 guides the entire group of steel sections 13 upward and out of the zinc pot, and the air knife installed on the magnetic roller frame 16 blows the excess zinc liquid back into the zinc pot.

[0041] ⑥In Figure 9 After the middle group of steel 13 enters the inclined roller 7, it enters the next process. Once the material hook group is reset, it enters the next round of circulation.

[0042] ⑦ When the zinc pot 15 requires slag removal or regular inspection, the galvanizing mechanism translation mechanism 9 moves the entire actuator assembly along the galvanizing translation track 11 to the outside of the zinc pot. The magnetic roller translation mechanism 6 moves the magnetic roller 8 along the magnetic roller translation track 10 to the outside of the zinc pot, clearing the zinc pot and facilitating slag removal and inspection. After the operation is completed, each mechanism returns to its working position.

[0043] ⑧ Figure 10 The figure shows the lifting hook 5 lifting the entire set of steel sections 13 onto the magnetic roller 8. The magnetic roller 8 uses its own magnetic force to attract the entire set of steel sections 13 to the roller body and transport it upward. The air knife 14 blows the excess zinc liquid on the entire set of steel sections 13 back to the zinc pot 15 through the inclined air outlet. After the entire set of steel sections 13 is completely attracted to the magnetic roller 8 and transported upward stably, the lifting hook 5 descends to its initial position.

[0044] ⑨ Figure 11 The figure shows the relative positional relationship between the entire set of steel sections 13, the magnetic roller 8 and the wind knife 14 from a perspective perpendicular to the entire set of steel sections 13.

[0045] ⑩ Figure 12 The main body of the equipment shown is driven by the galvanizing mechanism translation travel mechanism 9 and moves along the galvanizing mechanism translation track 11 to the slag scooping position.
