[0001] The invention relates to the field of metal plating, in particular to a hot-dip galvanizing device for an insulator steel cap. Background Art

[0002] The purpose of galvanizing the surface of the insulator steel cap is to improve its corrosion resistance, extend its service life, and ensure the safe and stable operation of power facilities. Through galvanizing, a dense zinc coating can be formed on the surface of the insulator steel cap, which plays the role of sacrificial anode protection and improves the weather resistance and appearance quality of the steel cap. This is a commonly used anti-corrosion measure in the power industry and is widely used in power facilities such as insulators.

[0040] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0041] like Figure 1-Figure 8 As shown, an insulator steel cap hot-dip galvanizing device includes a loading ring 100, a support frame 200, a rotating drive assembly 300 and a moving drive assembly 400. There are multiple loading rings 100, the multiple loading rings 100 are concentric, and the diameters of the multiple loading rings 100 decrease from the outside to the inside. Loading pins 110 are evenly spaced on the circumference of the loading ring 100. The rotating drive assembly 300 is arranged on the support frame 200. The rotating drive assembly 300 is used to drive the multiple loading rings 100 to rotate at the same speed. The moving drive assembly 400 is also arranged on the support frame 200. The moving drive assembly 400 is used to drive the multiple loading rings 100 to move relative to each other along the axis of the loading ring 100, so that the multiple loading rings 100 have a galvanized state and a zinc-throwing state in the vertical direction. When in the galvanized state, the multiple loading rings 100 are at the same vertical height. When in the zinc-throwing state, the multiple loading rings 100 are arranged in an inverted cone shape in the vertical direction.

[0042] It should be additionally explained that a zinc material pool 500 is disposed at the lower portion of the support frame 200 .

[0043] Before galvanizing, the staff first installs the steel cap 700 on the loading pin 110, and then uses the moving drive component 400 to make multiple loading rings 100 at the same vertical height in the vertical direction. At this time, the multiple loading rings 100 are in a galvanized state. Next, the multiple loading rings 100 are moved downward at the same time, so as to be immersed in the zinc material pool 500 to a preset depth and maintained for a preset time. Then, the multiple loading rings 100 are moved upward at the same time and removed from the zinc material pool 500. Next, the moving drive component 400 is used to arrange the multiple loading rings 100 in an inverted cone shape in the vertical direction. At this time, the multiple loading rings 100 are in a zinc throwing state. Next, the rotating drive component 300 is started to make the multiple loading rings 100 rotate at the same speed, and the excess zinc liquid on the steel cap 700 is centrifugally thrown out to ensure the consistency of the zinc layer thickness and zinc layer color of the steel cap 700 after hot-dip galvanizing.

[0044] It is understandable that, since all the steel caps 700 are in the zinc liquid at the same depth during galvanizing, the fluidity of the hot zinc liquid plated on the surface of the steel caps 700 is basically the same, and the thickness of the zinc layer will not be inconsistent due to the difference in the fluidity of the hot zinc liquid plated on the surface of the steel caps 700 during zinc throwing. In addition, since the multiple carrier rings 100 are at the same vertical height during the galvanizing state, the plating time of the steel caps 700 in the zinc material pool 500 is also completely consistent, and the plating thickness of the zinc layer will not be inconsistent due to the difference in plating time. During zinc throwing, the steel caps 700 corresponding to each carrier ring 100 are located at different vertical heights, and the zinc liquid thrown off does not affect each other, and the zinc layer thickness of the steel caps 700 will not be affected because the zinc liquid is thrown onto the steel caps 700 corresponding to other carrier rings 100.

[0045] It should also be noted that a connecting groove 710 is provided on the steel cap 700 , and the connecting groove 710 is used to cooperate with the material carrying pin 110 so as to hang the steel cap 700 on the material carrying pin 110 .

[0046] In a further embodiment, Figure 2-Figure 4As shown, there are three material carrying rings 100, and the rotation drive assembly 300 includes a rotating rod 310, an outer rotating sleeve 320 and an inner rotating sleeve 330. The lower end of the rotating rod 310 is coaxially fixedly connected to the material carrying ring 100 with the smallest diameter, and the end of the rotating rod 310 away from the material carrying ring 100 is fixedly connected to a pinion 340, and the pinion 340 can rotate around its axis. The inner rotating sleeve 330 is sleeved on the outside of the rotating rod 310, and the lower end of the inner rotating sleeve 330 is fixed to the material carrying ring 100 with the middle diameter. The upper end of the inner rotating sleeve 330 is fixedly connected with a middle gear 350, and the middle gear 350 can rotate around its axis. The outer rotating sleeve 320 is sleeved on the outside of the inner rotating sleeve 330, and the lower end of the outer rotating sleeve 320 is coaxially fixedly connected with the loading ring 100 with the largest diameter. The upper end of the outer rotating sleeve 320 is fixedly connected with a large gear 360, and the large gear 360 can rotate around its axis. The large gear 360 is located below the middle gear 350 and the diameter of the large gear 360 is greater than the diameter of the small gear 340.

[0047] Taking the number of three loading rings 100 as an example, when in use, the staff makes the small gear 340, the middle gear 350 and the large gear 360 rotate around their own axes. At this time, the small gear 340 drives the rotating rod 310 to rotate, the rotating rod 310 drives the loading ring 100 with the smallest diameter to rotate, the middle gear 350 drives the inner rotating sleeve 330 to rotate, the inner rotating sleeve 330 drives the loading ring 100 with a middle diameter to rotate, the large gear 360 drives the outer rotating sleeve 320 to rotate, and the outer rotating sleeve 320 drives the loading ring 100 with the largest diameter to rotate, thereby achieving the same speed rotation of the three loading rings 100 in the zinc throwing state.

[0048] In other embodiments, when the number of the carrying rings 100 is four, a sleeve may be further arranged on the outside of the outer rotating sleeve 320, so that the lower end of the sleeve is connected to the outermost carrying ring 100, and a corresponding gear is arranged on the upper end of the sleeve, and the outermost carrying ring 100 is driven to rotate by rotating the driving gear.

[0049] In a further embodiment, Figure 3 , Figure 4 and Figure 8As shown, the mobile drive assembly 400 includes a first hydraulic rod 410, a driving sleeve 420 and a sliding connecting plate 430. The sliding connecting plate 430 is slidably connected to the support frame 200, and the sliding connecting plate 430 can slide in the vertical direction. The driving sleeve 420 is arranged on the sliding connecting plate 430. A driving cover 440 is provided at the upper end of the sliding connecting plate 430 and above the driving sleeve 420. The fixed end of the first hydraulic rod 410 is arranged on the lower end surface of the driving cover 440. The telescopic end of the first hydraulic rod 410 is sleeved with the rotating rod 310, and the rotating rod 310 and the telescopic end of the first hydraulic rod 410 can move synchronously and rotate relative to each other. The driving sleeve 420 is sleeved on the outside of the outer rotating sleeve 320, and the outer rotating sleeve 320 and the driving sleeve 420 can move synchronously and rotate relative to each other.

[0050] It should be additionally explained that a rotation groove 331 is provided at the upper portion of the inner rotating sleeve 330 , and a support ring 311 is provided at the outside of the rotating rod 310 , and the support ring 311 is located in the rotation groove 331 .

[0051] like Figure 8 As shown, when the material carrying ring 100 needs to switch from the galvanizing state to the zinc throwing state, the telescopic end of the first hydraulic rod 410 is extended downward, and at this time, the telescopic end of the first hydraulic rod 410 drives the small gear 340 to move downward synchronously, and the small gear 340 drives the rotating rod 310 to move downward synchronously, and the rotating rod 310 drives the material carrying ring 100 with the smallest diameter to move downward synchronously. In the initial state, the middle gear 350 and the large gear 360 have a certain distance in the vertical direction. Under the cooperation of the support ring 311 and the revolving groove 331, the rotating rod 310 and the inner rotating sleeve 330 move downward synchronously, so the material carrying ring 100 with the middle diameter and the large gear 360 with the largest diameter move downward synchronously. There is a height difference in the vertical direction between the carrying rings 100. After the lower surface of the middle gear 350 contacts the upper surface of the large gear 360, the inner rotating sleeve 330 can no longer move downward synchronously with the rotating rod 310. At this time, the height difference between the carrying ring 100 with the middle diameter and the carrying ring 100 with the largest diameter no longer increases. The height difference is determined. Next, under the driving action of the first hydraulic rod 410, the rotating rod 310 continues to move downward to the lower limit position and then stops. At this time, the height difference in the vertical direction between the carrying ring 100 with the middle diameter and the carrying ring 100 with the smallest diameter is also determined. At this time, the states of the three carrying rings 100 are as follows: Figure 3 When the three loading rings 100 need to switch from the zinc throwing state to the galvanizing state, the telescopic end of the first hydraulic rod 410 is retracted and moved upward, and when the support ring 311 abuts against the upper end surface of the rotary groove 331, the inner rotating sleeve 330 is driven to move upward synchronously, thereby resetting the three loading rings 100 to the same vertical height of the galvanizing state.

[0052] In a further embodiment, Figure 5 As shown, a first motor 450 is provided on the inner circumferential wall of the driving sleeve 420, and the output end of the first motor 450 is fixedly connected to the first gear 451, and the first gear 451 is meshed with the large gear 360. The telescopic end of the first hydraulic rod 410 is also fixedly connected to a mounting frame 470, and a second motor 460 is provided on the upper part of the mounting frame 470, and the output end of the second motor 460 is fixedly connected to the second gear 461, and the second gear 461 is meshed with the small gear 340. A third motor 480 is provided on the lower part of the mounting frame 470, and the output end of the third motor 480 is fixedly connected to the third gear 481, and the third gear 481 is meshed with the middle gear 350.

[0053] When in use, the first motor 450, the second motor 460 and the third motor 480 are started, and the first motor 450 drives the large gear 360 to rotate through the first gear 451. At the same time, the second motor 460 drives the small gear 340 to rotate through the second gear 461, and the third motor 480 drives the middle gear 350 to rotate through the third gear 481, so that the three loading rings 100 rotate at the same speed through the speed regulation of the first motor 450, the second motor 460 and the third motor 480.

[0054] It should be supplemented that, since there is a relative displacement between the middle gear 350 and the third gear 481 in the vertical direction, in order to ensure the stability of the rotation of the gears, the tooth profiles of the middle gear 350 and the third gear 481 should both be helical teeth.

[0055] In a further embodiment, Figure 3 As shown, a second hydraulic rod 490 is provided between the top of the driving cover 440 and the support frame 200 , a fixed end of the second hydraulic rod 490 is arranged at the bottom of the support frame 200 , and a telescopic end of the second hydraulic rod 490 is fixedly connected to the driving cover 440 .

[0056] When the three loading rings 100 need to move synchronously, start the second hydraulic rod 490, and the telescopic end of the second hydraulic rod 490 drives the drive cover 440 to move synchronously, the drive cover 440 drives the sliding connecting plate 430 and the first hydraulic rod 410 to move synchronously, and the sliding connecting plate 430 drives the drive sleeve 420 to move synchronously, thereby making the three loading rings 100 move synchronously.

[0057] During the zinc throwing process, some zinc slag and zinc ash will inevitably exist around the zinc material pool 500, and these zinc slag and zinc ash will float on the surface of the hot zinc liquid. When the steel cap 700 is removed from the hot zinc liquid, the zinc slag and zinc ash may adhere to the surface of the steel cap 700. If the zinc slag and zinc ash are not removed during the zinc throwing process, zinc nodules will be formed on the surface of the steel cap 700, affecting the appearance quality of the steel cap 700. To solve this problem, in a further embodiment, an extrusion plate 510 is slidably connected to the zinc material pool 500, and a vertical bracket 520 is provided on the outside of the zinc material pool 500. The upper part of the vertical bracket 520 is fixedly connected to a third hydraulic rod 530, and the telescopic end of the third hydraulic rod 530 is fixedly connected to the upper surface of the extrusion plate 510. A fourth hydraulic rod 610 is fixedly connected to the lower surface of the sliding connecting plate 430, and a telescopic end of the fourth hydraulic rod 610 is fixedly connected to a zinc liquid circulation cylinder 620, which is located below the loading ring 100. A liquid outlet hole 622 is provided on the upper peripheral wall of the zinc liquid circulation cylinder 620, and a liquid inlet hole 621 is provided on the bottom of the zinc liquid circulation cylinder 620. A fifth hydraulic rod 630 is provided inside the zinc liquid circulation cylinder 620, and a plug ring 640 is fixedly connected to the telescopic end of the fifth hydraulic rod 630, and the plug ring 640 corresponds to the position of the liquid inlet hole 621.

[0058] It should be noted that, in the initial state, the plug ring 640 is located inside the liquid inlet hole 621 , that is, the liquid inlet hole 621 is in a blocked state, and at this time, the material cannot enter the zinc liquid circulation cylinder 620 .

[0059] At the beginning of galvanizing, the loading ring 100 is first placed in a galvanizing state, that is, multiple loading rings 100 are at the same vertical height, and then the second hydraulic rod 490 is moved downward. At this time, under the driving action of the second hydraulic rod 490, the loading ring 100 and the zinc liquid circulation cylinder 620 are synchronously moved downward. After multiple loading rings 100 move to a preset depth in the zinc material pool 500, the second hydraulic rod 490 stops moving. In this process, the height of the liquid inlet hole 621 is always higher than the liquid level in the zinc material pool 500. , and the bottom of the zinc liquid circulation cylinder 620 contacts the hot zinc liquid, so that the air inside the zinc liquid circulation cylinder 620 is heated, and the steel cap 700 is further preheated by the hot air to prevent the temperature difference between the steel cap 700 and the hot zinc liquid from being too large. Next, the telescopic end of the third hydraulic rod 530 moves downward, the telescopic end of the fourth hydraulic rod 610 moves downward, and the telescopic end of the fifth hydraulic rod 630 moves upward. The telescopic end of the third hydraulic rod 530 moves downward to drive the extrusion plate 510 to move downward synchronously, and the fourth hydraulic rod The telescopic end of 610 moves downward, driving the zinc liquid circulation cylinder 620 to move downward synchronously. At this time, the liquid level above the third hydraulic rod 530 increases, and the height of the upper end surface of the zinc liquid circulation cylinder 620 decreases. The hot zinc liquid gradually enters the zinc liquid circulation cylinder 620 through the liquid inlet hole 621, so that the liquid level of the hot zinc liquid in the zinc liquid circulation cylinder 620 gradually exceeds the height of the loading ring 100, thereby completing the zinc layer coating on the surface of the steel cap 700. In the process of the hot zinc liquid gradually covering the steel cap 700, due to the hot zinc liquid The hot zinc liquid enters the zinc liquid circulation cylinder 620 from the liquid inlet hole 621 below the liquid surface of the hot zinc liquid, so the liquid surface of the hot zinc liquid is constantly updated, which can not only maintain the temperature of the hot zinc liquid, but also prevent the surface of the hot zinc liquid from being oxidized into solid slag blocks due to long-term contact with air. In addition, due to the extrusion of the extrusion plate 510, the liquid surface of the zinc material pool 500 is also updated and changed, so even if zinc slag and zinc ash fall into the zinc material pool 500, they will be dispersed to various positions in the hot zinc liquid, and will not be concentrated on the surface of the hot zinc liquid.

[0060] When the liquid level in the zinc liquid circulation cylinder 620 is higher than the height of the liquid outlet hole 622, the hot zinc liquid in the zinc liquid circulation cylinder 620 is discharged outwardly through the liquid outlet hole 622 to the top of the extrusion plate 510. When the liquid levels inside and outside the zinc liquid circulation cylinder 620 are consistent, the zinc liquid circulation cylinder 620 stops moving downward. After a preset time, the material carrier ring 100 starts to be moved out of the zinc material pool 500. At this time, the telescopic end of the second hydraulic rod 490 is retracted and moved upward. In addition, the telescopic end of the fourth hydraulic rod 610 is also retracted and moved upward, so The hot zinc liquid inside the zinc liquid circulation cylinder 620 is gradually discharged outwardly into the zinc material pool 500 through the liquid outlet 622, so that the upper layer of the liquid surface of the zinc material pool 500 is updated and changed, thereby avoiding too much zinc slag and zinc ash concentrated on the upper surface of the zinc material pool 500, thereby avoiding that during the plating process, the uppermost layer of the liquid surface of the zinc material pool 500 remains unchanged, causing the zinc slag and zinc ash concentrated in the uppermost layer of the liquid surface to adhere to the surface of the steel cap 700, thereby reducing the size and number of zinc nodules on the surface of the steel cap 700, thereby achieving the effect of improving the appearance quality of the steel cap 700.

[0061] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described.
