Description

Technical Field

[0001] The invention belongs to the field of steel structure parts processing, in particular to a zinc infiltration device for corrosion protection of steel structure parts in underground mines and an operating method thereof. Background Art

[0002] Mining mainly includes one or more mining workshops and some auxiliary workshops. Most mines also include beneficiation plants. Mines include coal mines, metal mines, non-metallic building materials mines and chemical mines, etc. In the mining production process, mining operations consume the most manpower and material resources, occupy the most funds, and are the production link with the greatest potential for reducing mining costs. The main way to reduce mining costs is to improve labor productivity and product quality and reduce material consumption. When conducting underground mining work in a mine, it is necessary to use plate-shaped steel structure parts to build a platform. In order to prevent the plate-shaped steel structure parts from rusting and corroding in the mine, the plate-shaped steel structure parts need to be immersed in zinc liquid for zinc infiltration treatment before building the platform.

[0003] When steel structural parts are taken out of the zinc liquid, their own temperature is relatively high. Existing technology is not convenient for slowly cooling the steel structural parts. Cooling the steel structural parts too quickly after zinc infiltration will change the structure of the zinc layer, and the grains in the zinc layer will become coarse, resulting in a decrease in the toughness and corrosion resistance of the zinc layer. In addition, defects such as pores and sand holes will appear on the surface of the zinc layer, affecting the appearance quality and protective performance of the zinc layer. In addition, the steel structural parts need to be placed in the zinc liquid through a fixture, and the part of the steel structural parts that contacts the fixture is difficult to contact the zinc liquid, resulting in the inability to form an effective zinc layer on this part of the steel structural parts.

[0004] To this end, the present invention provides a zinc infiltration device for corrosion protection of steel structure parts in underground mines and an operating method thereof. Summary of the Invention

[0005] In order to make up for the shortcomings of the existing technology and solve the problem that the temperature of steel structure parts is high when they are taken out of the zinc liquid, the existing technology is not convenient for slowly cooling the steel structure parts, and the cooling of the steel structure parts after zinc infiltration is too fast will cause the organizational structure of the zinc layer to change, and the grains in the zinc layer will become coarse, resulting in a decrease in the toughness and corrosion resistance of the zinc layer. In addition, defects such as pores and sand holes will appear on the surface of the zinc layer, affecting the appearance quality and protective performance of the zinc layer. In addition, the steel structure parts need to be placed in the zinc liquid through a clamp, and the part of the steel structure parts that contacts the clamp is difficult to contact the zinc liquid, resulting in the problem that an effective zinc layer cannot be formed on this part of the steel structure parts.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The present invention relates to a zinc-diffusion device for corrosion protection of steel structural parts in underground mines and an operating method thereof. When the steel structural parts are immersed in zinc liquid, they are controlled by a first motor to move back and forth up and down, thereby allowing various parts of the steel structural parts to be in more sufficient and uniform contact with the zinc liquid, thereby avoiding the situation where excessive zinc liquid adheres to some parts and insufficient zinc liquid adheres to other parts due to long-term stillness. In addition, the cooperation of the protrusion and the push plate allows the steel structural parts to swing back and forth left and right in the mounting frame, avoiding continuous contact between the steel structural parts and the pulley, so that different positions of the steel structural parts can be immersed in zinc liquid.

[0020] 2. The zinc-diffusion device for corrosion protection of steel structure parts in underground mines and the operating method thereof described in the present invention limit the steel structure parts on both sides by a plurality of pulleys, so that the steel structure parts can be stored in the mounting frame. The contact surface between the pulley and the steel structure parts is small, which can reduce the obstruction of the steel structure parts and enable the zinc liquid to more fully contact the steel structure parts.

[0021] 3. The present invention describes a zinc infiltration device for corrosion protection of steel structure parts in underground mines and an operating method thereof. When controlling the steel structure parts moved out of the box to continue to move upward, the hot air pump is started and hot air is blown out through the contact between the first contact and the second contact. The hot air is blown out obliquely downward to keep the steel structure parts moving upwards warm. The hot air is wrapped by a set sleeve to prevent the blown hot air from dispersing quickly. When the hot air circulates downward, it is guided by the inclined surface on the top of the guide block, so that the hot air can hit the steel structure parts, thereby achieving a better insulation effect on the steel structure parts.

[0022] 4. The zinc-diffusion device for corrosion protection of steel structure parts in underground mines and the operating method thereof described in the present invention facilitate downward blowing of excess zinc liquid adhering to the surface of the steel structure parts by means of downwardly blowing hot air, so that the excess zinc liquid can slide downward along the surface of the steel structure parts and fall back into the box. This not only cleans the excess zinc liquid on the surface of the steel structure parts, but also allows the zinc liquid to be recycled, thus avoiding waste of zinc liquid. When controlling the steel structure parts removed from the box to move downward, the hot air pump is powered off to avoid blowing the zinc liquid adhering to the surface of the steel structure parts upward.

[0023] 5. The zinc-diffusion device for corrosion protection of steel structure parts in underground mines and the operating method thereof described in the present invention move the steel structure parts upward and clean the zinc liquid. At the same time, the steel structure parts are shaken left and right through the cooperation of the protrusion and the push plate to avoid residual zinc liquid at the position where the steel structure parts are in contact with the pulley.

The tops of the two groups of support frames 11 are fixedly connected to a top plate 12. The outer walls of the first sliding shafts 9 are symmetrically sleeved with two first springs 10, one end of the first spring 10 is fixedly connected to the slide plate 7, and the other end of the first spring 10 is fixedly connected to the support frame 11. A clamping assembly is provided at the bottom of the top plate 12; the clamping assembly includes two groups of connecting frames 13, and the two groups of connecting frames 13 are symmetrically fixedly installed on the bottom of the top plate 12. The bottom of the connecting frame 13 is fixedly connected to a mounting frame 14, and the mounting frame 14 is set to a hollow structure; a number of rotating shafts 15 are equidistantly fixedly connected to the inner wall of the mounting frame 14, and the outer wall of the rotating shaft 15 is rotatably connected to a pulley 16.

[0038] Through the above technical solution, the zinc liquid is put into the box body 1 by opening the feed port 31, and the steel structure parts are put into the mounting frame 14. The steel structure parts are limited on both sides by a plurality of pulleys 16, so that the steel structure parts can be stored in the mounting frame 14. The contact surface between the pulley 16 and the steel structure parts is small, which can reduce the shielding of the steel structure parts and enable the zinc liquid to more fully contact the steel structure parts. The hydraulic cylinder 2 is started to control the bracket 3 to move downward, so that the support plate 4 moves downward, drives the first motor 5 to move downward, drives the slide plate 7 to move downward, drives the support frame 11 to move downward, moves the top plate 12 downward, drives the mounting frame 14 to move downward, and the steel structure parts are immersed in the zinc liquid.

[0039] Specifically, the top of the bracket 3 is symmetrically fixedly connected to two side panels 17, and the outer walls of the two side panels 17 are equidistantly fixedly connected to a group of protrusions 18, each group of protrusions 18 is set to a number, and the two groups of protrusions 18 are staggered. The top and bottom of the protrusions 18 are set to be inclined, and the outer walls of the two support frames 11 are fixedly connected to push plates 19, which are used in conjunction with the push plates 19; the top of the box body 1 and above the feed port 31 is fixedly connected to a sleeve box 32, and the inner wall of the sleeve box 32 is symmetrically fixed. Two sets of heat pumps 33 are connected, and the air outlet of the heat pump 33 is set to be tilted downward. The outer wall of the slide 7 is provided with an electrified component; the inner wall of the sleeve box 32 is symmetrically fixedly connected with two sets of guide blocks 34, and the top of the guide block 34 is set to an inclined surface; the electrified component includes two fixing frames 20, and the two fixing frames 20 are symmetrically fixedly installed on the top of the slide 7. The inner wall of the fixing frame 20 is fixedly connected with a second sliding shaft 21, and the outer wall of the second sliding shaft 21 is slidably connected with a slider 23, and the outer wall of the second sliding shaft 21 is provided with The second spring 22, the bottom of the second spring 22 is fixedly connected to the fixed frame 20, the top of the second spring 22 is fixedly connected to the slider 23, the inner wall of the fixed frame 20 and located below the slider 23 are fixedly connected with a first contact 24, the outer wall of the slider 23 is fixedly connected with a second contact 25, the first contact 24 and the second contact 25 contact the hot air pump 33 to energize and operate, the inner wall of the slider 23 is slidably connected with a block 26, one side of the block 26 is fixedly connected with a third spring 27, the third spring 27 is fixedly connected to the slider 23, the elastic force of the third spring 27 is greater than the elastic force of the second spring 22, the other side of the block 26 is set as an inclined surface, the top of the limit shaft 8 is fixedly connected with a positioning plate 30, the bottom of the block 26 is provided with an inclined groove 28, the top of the slide plate 7 is fixedly connected with an inserting plate 29, and the bottom of the slider 23 is provided with an empty slot for matching the inserting plate 29; the bottom of the box body 1 is fixedly connected with a second motor 35, and the output end of the second motor 35 extends to the interior of the box body 1 and is fixedly connected with a stirring blade 36.

[0040] By the above technical solution, when the slide plate 7 moves back and forth up and down, it drives the push plate 19 to move back and forth up and down. When the push plate 19 moves to a position close to the protrusion 18, the inclined surface of the protrusion 18 presses against the push plate 19, pushing the push plate 19 to move to one side, driving the support frame 11 to move to one side, causing the top plate 12 to move to one side, driving the mounting frame 14 to move to one side, and causing the steel structure parts to move to one side. While the support frame 11 moves, the first spring 10 on one side is pressed. When the push plate 19 moves to a position disengaged from the protrusion 18, under the action of the first spring 10, the support frame 11 moves back, driving the mounting frame 14 to move back and forth, causing the steel structure parts to move back. Thus, while the mounting frame 14 moves back and forth up and down, the steel structure parts are moved back and forth on the mounting frame 1 4 reciprocating left and right to avoid the steel structure parts from being in continuous contact with the pulley 16, so that different positions of the steel structure parts can be immersed in the zinc liquid, and at the same time the second motor 35 is started to drive the stirring blade 36 to rotate, so that the temperature and composition of the zinc liquid are more uniform, avoiding the situation where the local temperature is too high or too low, and the uneven distribution of alloy elements in the zinc liquid. After the zinc infiltration of the steel structure parts is completed, the bracket 3 is controlled by the hydraulic cylinder 2 to move upward, so that the support plate 4 moves upward, drives the first motor 5 to move upward, moves the slide plate 7 upward, drives the support frame 11 to move upward, moves the top plate 12 upward, drives the mounting frame 14 to move upward, and moves the steel structure parts out of the box 1. At this time, the steel structure parts are located in the sleeve box 32, and the first motor 5 is started to control the slide plate 7 to move up and down again. When the slide plate 7 moves upward, the fixing frame 20 moves upward, driving the slider 23 to move upward, and the block 26 moves upward. When the block 26 moves to the position of the positioning plate 30, the positioning plate 30 presses against the straight surface of the top of the block 26. Under the limit of the positioning plate 30, the block 26 cannot continue to move upward, and the slider 23 cannot continue to move upward. When the first contact 24 on the inner wall of the fixing frame 20 moves to the position of the second contact 25, the two fit each other, so that the heat pump 33 starts and blows out hot air. The hot air is blown out obliquely downward to keep the steel structure parts moving upward warm. As the steel structure parts move upward, the hot air blown downward is used to blow away the excess zinc liquid adhering to the surface of the steel structure parts, so that the excess zinc liquid can flow along the steel structure parts. The surface slides downward and falls back into the box 1, thereby not only cleaning the excess zinc liquid on the surface of the steel structure parts, but also recycling the zinc liquid, avoiding the waste of zinc liquid. The hot air is wrapped by the set box 32 to prevent the blown hot air from dispersing quickly. When the hot air circulates downward, it is guided by the top inclined surface of the guide block 34, so that the hot air can hit the steel structure parts, which has a better insulation effect on the steel structure parts, avoids the steel structure parts from cooling too quickly, and can better clean the zinc liquid on the surface of the steel structure parts. While moving the steel structure parts upward and cleaning the zinc liquid, the steel structure parts are shaken left and right again through the cooperation of the protrusion 18 and the push plate 19 to avoid residual zinc liquid at the position where the steel structure parts are in contact with the pulley 16. When the slide plate 7 moves to the top,The steel structure part is driven to move to the top, the second spring 22 is compressed, the insert plate 29 is inserted into the slider 23 along the empty slot, and presses against the inclined slot 28 at the bottom of the block 26. Under the pressure of the insert plate 29, the block 26 moves into the slider 23, compressing the third spring 27. After the block 26 moves, it separates from the positioning plate 30. After losing the limit of the positioning plate 30, the slider 23 is quickly moved upward and reset under the action of the second spring 22, separating the second contact 25 from the first contact 24, thereby causing the zinc liquid on the surface of the steel structure part to The bottom of the steel structure part is blown straight, and then the slide plate 7 is controlled to move downward, driving the slider 23 to move downward. When the slider 23 moves to the position of the positioning plate 30, the positioning plate 30 presses against the inclined surface at the bottom of the clamping block 26. Under the pressure of the positioning plate 30, the clamping block 26 moves into the slider 23, compressing the third spring 27 again. When the slider 23 moves below the positioning plate 30, the action of the third spring 27 resets the clamping block 26, making it easier for the hot air pump 33 to blow out hot air when the steel structure part is controlled to move upward next time.

[0041] A sherardizing device for anti-corrosion of steel structure parts in underground mines and an operating method thereof. The operating method is applicable to the above-mentioned sherardizing device for anti-corrosion of steel structure parts in underground mines. The operating method steps are as follows:

[0042] S1: Place the zinc solution into the box 1, place the steel structure parts into the mounting frame 14, and control the mounting frame 14 to move downward so that the steel structure parts are immersed in the zinc solution;

[0043] S2: Start the first motor 5 to control the steel structure parts immersed in the zinc solution to move up and down reciprocatingly, and start the second motor 35 to control the stirring blade 36 to rotate and stir the zinc solution;

[0044] S3: Start the hydraulic cylinder 2 to control the sherardized steel structure parts to move out of the box 1, start the first motor 5 to control the steel structure parts to move up and down, and blow hot air through the hot air pump 33 to slowly cool the steel structure parts.

[0045] During use, the zinc liquid is put into the box body 1 through the feed port 31, and the steel structure parts are put into the mounting frame 14. The steel structure parts are limited on both sides by a number of pulleys 16 so that the steel structure parts can be stored in the mounting frame 14. The contact surface between the pulley 16 and the steel structure parts is small, which can reduce the shielding of the steel structure parts and enable the zinc liquid to more fully contact the steel structure parts. The hydraulic cylinder 2 is started to control the bracket 3 to move downward, so that the support plate 4 moves downward, drives the first motor 5 to move downward, moves the slide plate 7 downward, drives the support frame 11 to move downward, moves the top plate 12 downward, drives the mounting frame 14 downward, and immerses the steel structure parts in the zinc liquid. The first motor 5 is started to drive the screw rod 6 to rotate, and controls the slide plate 7 to move up and down reciprocatingly. The support frame 11 is driven to move up and down reciprocatingly, so that the top plate 12 moves up and down reciprocatingly, and the mounting frame 14 is driven to move up and down reciprocatingly, so that the steel structure parts move up and down reciprocatingly in the zinc liquid, thereby making each part of the steel structure parts more fully and evenly contact with the zinc liquid, avoiding the situation where the zinc liquid adheres too much to some parts and insufficient to some parts due to long-term static state, and in the process of moving up and down, a certain flushing and stirring effect is generated between the surface of the steel structure parts and the zinc liquid, which helps to remove the tiny impurities and oxide film that may exist on the surface of the parts, so that the zinc liquid can better contact with the substrate of the steel structure parts. When the slide plate 7 moves up and down reciprocatingly, it drives the push plate 19 to move up and down reciprocatingly. When the push plate 19 moves to a position close to the protrusion 18, the inclined surface of the protrusion 18 The surface is pressed against the push plate 19, pushing the push plate 19 to move to one side, driving the support frame 11 to move to one side, causing the top plate 12 to move to one side, driving the mounting frame 14 to move to one side, and causing the steel structure parts to move to one side. While the support frame 11 moves, the first spring 10 on one side is pressed. When the push plate 19 moves to a position disengaged from the protrusion 18, under the action of the first spring 10, the support frame 11 moves back, driving the mounting frame 14 to move back and forth, causing the steel structure parts to move back. Thus, while the mounting frame 14 moves back and forth up and down, the steel structure parts are caused to swing back and forth inside the mounting frame 14, avoiding continuous contact between the steel structure parts and the pulley 16, so that different positions of the steel structure parts can be soaked in zinc liquid. At the same time, the second motor 35 is started to drive the stirring blade 36 rotates to make the temperature and composition of the zinc liquid more uniform, avoid local temperature being too high or too low, and uneven distribution of alloy elements in the zinc liquid. After the zinc infiltration of the steel structure parts is completed, the hydraulic cylinder 2 controls the bracket 3 to move upward, so that the support plate 4 moves upward, drives the first motor 5 to move upward, drives the slide plate 7 to move upward, drives the support frame 11 to move upward, drives the top plate 12 to move upward, drives the mounting frame 14 to move upward, and moves the steel structure parts out of the box 1. At this time, the steel structure parts are located in the sleeve box 32. Start the first motor 5 and control the slide plate 7 to move up and down again. When the slide plate 7 moves upward, the fixing frame 20 moves upward, drives the slider 23 to move upward, and moves the clamping block 26 upward. When the clamping block 26 moves to the position of the positioning plate 30,The positioning plate 30 is pressed against the straight surface of the top of the block 26. Under the limit of the positioning plate 30, the block 26 cannot continue to move upward, and the slider 23 cannot continue to move upward. When the first contact 24 on the inner wall of the fixing frame 20 moves to the position of the second contact 25, the two fit each other, so that the heat pump 33 starts and blows out hot air. The hot air is blown out obliquely downward to keep the steel structure parts moving upward warm. As the steel structure parts move upward, the hot air blown downward can blow away the excess zinc liquid adhered to the surface of the steel structure parts, so that the excess zinc liquid can slide down along the surface of the steel structure parts and The hot air is then blown back into the casing 1, which not only cleans the excess zinc liquid on the surface of the steel structure parts, but also recycles the zinc liquid, thus avoiding waste of the zinc liquid. The hot air is wrapped by the provided sleeve 32 to prevent the blown hot air from dispersing quickly. When the hot air flows downward, it is guided by the top inclined surface of the guide block 34, so that the hot air can hit the steel structure parts, which has a better heat preservation effect on the steel structure parts, avoids the steel structure parts from cooling too quickly, and can better clean the zinc liquid on the surface of the steel structure parts. While moving the steel structure parts upward and cleaning the zinc liquid, the protrusion 18 cooperates with the push plate 19 to The steel structure parts are made to rock left and right to avoid residual zinc liquid at the position where the steel structure parts are in contact with the pulley 16. When the slide plate 7 moves to the uppermost position, it drives the steel structure parts to move to the uppermost position, the second spring 22 is compressed, and the inserting plate 29 is inserted into the slider 23 along the empty slot and pressed against the inclined slot 28 at the bottom of the clamping block 26. Under the pressure of the inserting plate 29, the clamping block 26 moves into the slider 23, compressing the third spring 27. After the clamping block 26 moves, it separates from the positioning plate 30. After losing the limit of the positioning plate 30, under the action of the second spring 22, the slider 23 moves upward quickly and resets, so that the second contact 25 is in contact with the The first contact 24 separates, allowing the zinc liquid on the surface of the steel part to be blown straight to the bottom of the steel part. The slide plate 7 is then controlled to move downward, driving the slider 23 downward. When the slider 23 moves to the position of the positioning plate 30, the positioning plate 30 presses against the inclined surface at the bottom of the clamping block 26. Under the pressure of the positioning plate 30, the clamping block 26 moves into the slider 23, compressing the third spring 27 again. When the slider 23 moves below the positioning plate 30, the action of the third spring 27 resets the clamping block 26, facilitating the next upward movement of the steel part, allowing the hot air pump 33 to blow out hot air.
