Description

Technical Field

[0001] The present invention belongs to the field of steel structure part processing, and specifically relates to a zinc impregnation device for anti-corrosion of steel structure parts in underground mines and its operation method. Background Art

[0002] Mining mainly includes one or more mining workshops and some auxiliary workshops. Most mines also include ore dressing plants. Mines include coal mines, metal mines, non-metal mine building material mines, chemical mines, etc. In the process of mine production, the excavation operation not only consumes the most manpower and material resources and occupies the most funds, but also has the greatest potential for reducing the mining cost. The main ways to reduce the excavation cost are to improve labor productivity and product quality, and reduce material consumption. When carrying out underground mining work in the mine, it is often necessary to use plate-shaped steel structure parts to build a platform. 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 impregnation treatment before building the platform.

[0003] When the steel structure parts are taken out of the zinc liquid, their own temperature is relatively high. The existing technology is not convenient for slowly cooling the steel structure parts. If the steel structure parts are cooled too quickly after zinc impregnation, the organizational structure of the zinc layer will change, the grains in the zinc layer will become coarser, resulting in a decrease in the toughness and corrosion resistance of the zinc layer. In addition, it will also cause defects such as pores and sand holes 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 put into the zinc liquid through fixtures, and the part of the steel structure parts in contact with the fixtures is difficult to contact the zinc liquid, resulting in the inability of this part of the steel structure parts to form an effective zinc layer.

[0004] Therefore, the present invention provides a zinc impregnation device for anti-corrosion of steel structure parts in underground mines and its operation method. Summary of the Invention

In addition, the steel structure parts need to be put into the zinc liquid through fixtures, and the part of the steel structure parts in contact with the fixtures is difficult to contact the zinc liquid, resulting in the inability of this part of the steel structure parts to form an effective zinc layer, the present invention proposes a zinc impregnation device for anti-corrosion of steel structure parts in underground mines and its operation method.

[0015] The beneficial effects of the present invention are as follows: 1. For the zinc permeation device and the operation method for anti-corrosion of steel structure parts in underground mines of the present invention, when the steel structure parts are immersed in the zinc liquid, the first motor is used to control their reciprocating up and down movement, so that all parts of the steel structure parts can come into contact with the zinc liquid more fully and evenly, avoiding the situation that some parts have too much zinc liquid attachment and some parts have insufficient attachment due to long-term stillness. And through the cooperation of the convex block and the push plate, the steel structure parts swing reciprocally left and right in the mounting frame, avoiding the continuous contact of the steel structure parts with the pulley, and facilitating the immersion of different positions of the steel structure parts in the zinc liquid.

[0016] 2. The zinc permeation device and its operation method for anti-corrosion of steel structure parts in underground mines of the present invention limit both sides of the steel structure parts through a plurality of pulleys, enabling the steel structure parts to be stored in the mounting frame.

Detailed implementation manners

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0024] As Figures 1 to 10As shown in the figure, the present invention provides a technical solution, a zinc infiltration device for anti-corrosion of steel structure parts in underground mines, including a box body 1. Two feeding ports 31 are symmetrically opened at the top of the box body 1. Two groups of hydraulic cylinders 2 are symmetrically and fixedly connected inside the box body 1. The output ends of the two groups of hydraulic cylinders 2 are fixedly connected with brackets 3. A support plate 4 is fixedly connected between the two brackets 3. A lifting assembly is arranged at the bottom of the support plate 4. The lifting assembly includes a first motor 5. The first motor 5 is fixedly installed at the bottom of the support plate 4. The output end of the first motor 5 penetrates through the support plate 4 and is fixedly connected with a lead screw 6. The outer wall of the lead screw 6 is connected with a slide plate 7 through a lead screw nut pair. Two limit shafts 8 are symmetrically and fixedly connected to the top of the support plate 4. Both of the two limit shafts 8 are slidably connected with the slide plate 7. Two groups of first sliding shafts 9 are symmetrically and fixedly connected to the top of the slide plate 7. The outer walls of the two groups of first sliding shafts 9 are slidably connected with support frames 11. The tops of the two groups of support frames 11 are fixedly connected with a top plate 12. Two first springs 10 are symmetrically sleeved on the outer wall of the first sliding shaft 9. One end of the first spring 10 is fixedly connected with the slide plate 7, and the other end of the first spring 10 is fixedly connected with the support frame 11. A clamping assembly is arranged at the bottom of the top plate 12. The clamping assembly includes two groups of connecting frames 13. The two groups of connecting frames 13 are symmetrically and fixedly installed at the bottom of the top plate 12. The bottom of the connecting frame 13 is fixedly connected with a mounting frame 14. The mounting frame 14 is arranged in a hollow structure. A plurality of rotating shafts 15 are equidistantly and fixedly connected to the inner wall of the mounting frame 14. A pulley 16 is rotatably connected to the outer wall of the rotating shaft 15.

[0025] Through the above technical solution, the zinc liquid is put into the box body 1 through the opened feeding port 31. The steel structure part is put into the mounting frame 14. The two sides of the steel structure part are limited by a plurality of pulleys 16, so that the steel structure part can be stored in the mounting frame 14. And the contact surface between the pulley 16 and the steel structure part is small, which can reduce the shielding of the steel structure part, so that the zinc liquid can contact the steel structure part more fully. The hydraulic cylinder 2 is started, and the bracket 3 is controlled to move downward, so that the support plate 4 moves downward, driving the first motor 5 to move downward, making the slide plate 7 move downward, driving the support frame 11 to move downward, making the top plate 12 move downward, driving the mounting frame 14 to move downward, so that the steel structure part is immersed in the zinc liquid. The first motor 5 is started, driving the lead screw 6 to rotate, controlling the slide plate 7 to reciprocate up and down, driving the support frame 11 to reciprocate up and down, making the top plate 12 reciprocate up and down, driving the mounting frame 14 to reciprocate up and down, so that the steel structure part reciprocates up and down in the zinc liquid. Thus, all parts of the steel structure part can contact the zinc liquid more fully and evenly, avoiding the situation that some parts have too much zinc liquid attachment and some parts have insufficient attachment due to long-term stillness. And during the up and down movement, a certain scouring and stirring effect is generated between the surface of the steel structure part and the zinc liquid, which helps to remove the possible tiny impurities and oxide films on the part surface, so that the zinc liquid can better contact the matrix of the steel structure part.

[0026] Specifically, two side plates 17 are symmetrically and fixedly connected to the top of the support 3. A group of bumps 18 are equidistantly and fixedly connected to the outer walls of the two side plates 17. Each group of bumps 18 is provided with a plurality of them. The two groups of bumps 18 are installed in a staggered manner. The top and bottom of the bump 18 are both provided with inclined surfaces. Push plates 19 are fixedly connected to the outer walls of the two support frames 11. The push plates 19 are used in cooperation with the bumps 18; a sleeve box 32 is fixedly connected to the top of the box body 1 and above the feed port 31. Two groups of hot air pumps 33 are symmetrically and fixedly connected to the inner wall of the sleeve box 32. The air outlet of the hot air pump 33 is inclined downward. An energization assembly is arranged on the outer wall of the sliding plate 7; two groups of flow guiding blocks 34 are symmetrically and fixedly connected to the inner wall of the sleeve box 32. The top of the flow guiding block 34 is provided with an inclined surface; the energization assembly includes two fixing frames 20. The two fixing frames 20 are symmetrically and fixedly installed on the top of the sliding plate 7. A second sliding shaft 21 is fixedly connected to the inner wall of the fixing frame 20. A slider 23 is slidably connected to the outer wall of the second sliding shaft 21. A second spring 22 is sleeved on the outer wall of the second sliding shaft 21. The bottom of the second spring 22 is fixedly connected to the fixing frame 20. The top of the second spring 22 is fixedly connected to the slider 23. A first contact 24 is fixedly connected to the inner wall of the fixing frame 20 and below the slider 23. A second contact 25 is fixedly connected to the outer wall of the slider 23. When the first contact 24 contacts the second contact 25, the hot air pump 33 is energized and operates. A clamping block 26 is slidably connected to the inner wall of the slider 23. One side of the clamping block 26 is fixedly connected to 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 clamping block 26 is provided with an inclined surface. A positioning plate 30 is fixedly connected to the top of the limiting shaft 8. An inclined groove 28 is opened at the bottom of the clamping block 26. An insertion plate 29 is fixedly connected to the top of the sliding plate 7. An empty groove for cooperating with the insertion plate 29 is opened at the bottom of the slider 23; a second motor 35 is fixedly connected to the bottom of the box body 1. The output end of the second motor 35 extends into the box body 1 and is fixedly connected to a stirring blade 36.

[0027] Through the above technical solution, when the skateboard 7 reciprocates up and down, it drives the push plate 19 to reciprocate up and down. When the push plate 19 moves to a position close to the convex block 18, the inclined surface of the convex block 18 abuts 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 part to move to one side. While the support frame 11 moves, it compresses the first spring 10 on one side. When the push plate 19 moves to a position away from the convex block 18, under the action of the first spring 10, the support frame 11 moves back, driving the mounting frame 14 to reciprocate and causing the steel structure part to move back. Thus, reciprocatingly, while the mounting frame 14 reciprocates up and down, the steel structure part reciprocates left and right within the mounting frame 14, avoiding continuous contact between the steel structure part and the pulley 16, enabling different positions of the steel structure part to be soaked by the zinc liquid. At the same time, the second motor 35 is started to drive the stirring blade 36 to rotate, making the temperature and composition of the zinc liquid more uniform, avoiding the situation of excessive or too low local temperature and uneven distribution of alloy elements in the zinc liquid. After the zinc infiltration of the steel structure part is completed, the hydraulic cylinder 2 controls the bracket 3 to move upward, causing the support plate 4 to move upward, driving the first motor 5 to move upward, making the skateboard 7 move upward, driving the support frame 11 to move upward, causing the top plate 12 to move upward, driving the mounting frame 14 to move upward, and moving the steel structure part out of the box body 1. At this time, the steel structure part is located within the sleeve box 32. The first motor 5 is started, and the skateboard 7 is again controlled to reciprocate up and down. When the skateboard 7 moves upward, the fixed frame 20 moves upward, driving the slider 23 to move upward, making the clamping block 26 move upward. When the clamping block 26 moves to the position of the positioning plate 30, the positioning plate 30 abuts against the straight surface at the top of the clamping block 26. Under the limitation of the positioning plate 30, the clamping block 26 cannot continue to move upward, and thus the slider 23 cannot continue to move upward. When the first contact point 24 on the inner wall of the fixed frame 20 moves to the position of the second contact point 25, the two are in mutual contact, starting the hot air pump 33 to blow hot air. The hot air is blown obliquely downward to keep warm the upward-moving steel structure part. And as the steel structure part moves upward, in cooperation with the downward-blowing hot air, it is convenient to blow the excess zinc liquid adhered to the surface of the steel structure part downward, enabling the excess zinc liquid to slide downward along the surface of the steel structure part and fall back into the box body 1 again. Thus, not only the excess zinc liquid on the surface of the steel structure part is cleaned, but the zinc liquid can also be recycled, avoiding waste of the zinc liquid. By arranging the sleeve box 32 to wrap the hot air, the blown hot air is prevented from quickly dispersing. When the hot air flows downward, through the guiding of the inclined surface at the top of the guiding block 34, the hot air can impact on the steel structure part, achieving a better heat preservation effect on the steel structure part, avoiding the steel structure part from cooling too quickly, and being able to better clean the zinc liquid on the surface of the steel structure part. While moving the steel structure part upward and cleaning the zinc liquid, through the cooperation of the convex block 18 and the push plate 19, the steel structure part is shaken left and right again, avoiding the remaining zinc liquid at the position where the steel structure part is in contact with the pulley 16. When the skateboard 7 moves to the uppermost position,Drive the steel structure part to move to the uppermost position. The second spring 22 is compressed. The insertion plate 29 is inserted into the slider 23 along the empty slot and abuts against the inclined slot 28 at the bottom of the clamping block 26. Under the extrusion of the insertion 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 quickly moves upward and resets, separating the second contact 25 from the first contact 24. Thus, the zinc liquid on the surface of the steel structure part is always blown straight to the bottom of the steel structure part. Subsequently, control the slide plate 7 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 abuts against the inclined surface at the bottom of the clamping block 26. Under the extrusion of the positioning plate 30, the clamping block 26 moves into the slider 23 again, compressing the third spring 27. When the slider 23 moves below the positioning plate 30, under the action of the third spring 27, the clamping block 26 resets, facilitating the hot air pump 33 to blow out hot air when controlling the steel structure part to move upward next time.,

[0028] A zinc infiltration device and its operation method for anti-corrosion of steel structure parts in underground mines. This operation method is applicable to the above-mentioned zinc infiltration device for anti-corrosion of steel structure parts in underground mines. The steps of this operation method are as follows: S1: Put the zinc liquid into the box body 1, put the steel structure part into the mounting frame 14, and control the mounting frame 14 to move downward so that the steel structure part is immersed in the zinc liquid; S2: Start the first motor 5, control the steel structure part immersed in the zinc liquid to move up and down reciprocally, start the second motor 35, and control the stirring blade 36 to rotate to stir the zinc liquid; S3: Start the hydraulic cylinder 2 to control the steel structure part that has completed zinc infiltration to move out of the box body 1, start the first motor 5 to control the steel structure part to move up and down reciprocally, and blow hot air through the hot air pump 33 to slowly cool the steel structure part.

[0029] During use, zinc liquid is put into the box body 1 through the feeding port 31 opened. Steel structure parts are put into the mounting rack 14. The two sides of the steel structure parts are limited by a number of pulleys 16, so that the steel structure parts can be stored in the mounting rack 14. Moreover, the contact surface between the pulley 16 and the steel structure part is small, which can reduce the shielding of the steel structure part, enabling the zinc liquid to contact the steel structure part more fully. Start the hydraulic cylinder 2, control the support 3 to move downward, make the support plate 4 move downward, drive the first motor 5 to move downward, make the slide plate 7 move downward, drive the support frame 11 to move downward, make the top plate 12 move downward, drive the mounting rack 14 to move downward, and immerse the steel structure parts in the zinc liquid. Start the first motor 5, drive the lead screw 6 to rotate, control the slide plate 7 to reciprocate up and down, drive the support frame 11 to reciprocate up and down, make the top plate 12 reciprocate up and down, drive the mounting rack 14 to reciprocate up and down, and make the steel structure parts reciprocate up and down in the zinc liquid. Thus, all parts of the steel structure parts can contact the zinc liquid more fully and evenly, avoiding the situation that some parts have too much zinc liquid attachment and some parts have insufficient attachment due to long-term stillness. And during the up and down movement, a certain scouring and stirring effect is generated between the surface of the steel structure part and the zinc liquid, which helps to remove the possible tiny impurities and oxide films on the part surface, enabling the zinc liquid to better contact the matrix of the steel structure part. When the slide plate 7 reciprocates up and down, it drives the push plate 19 to reciprocate up and down. When the push plate 19 moves to a position close to the convex block 18, the inclined surface of the convex block 18 abuts 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, making the top plate 12 move to one side, driving the mounting rack 14 to move to one side, and making the steel structure parts move to one side. While the support frame 11 moves, it compresses the first spring 10 on one side. When the push plate 19 moves to a position away from the convex block 18, under the action of the first spring 10, the support frame 11 moves back, driving the mounting rack 14 to reciprocate, and making the steel structure parts move back. Thus reciprocating, while the mounting rack 14 reciprocates up and down, the steel structure parts swing back and forth in the mounting rack 14, avoiding the continuous contact between the steel structure parts and the pulleys 16, enabling different positions of the steel structure parts to be immersed in the zinc liquid. At the same time, start the second motor 35, drive the stirring blade 36 to rotate, make the temperature and composition of the zinc liquid more uniform, and avoid the situation of too high or too low local temperature and uneven distribution of alloy elements in the zinc liquid. After the zinc infiltration of the steel structure parts is completed, control the support 3 to move upward through the hydraulic cylinder 2, make the support plate 4 move upward, drive the first motor 5 to move upward, make the slide plate 7 move upward, drive the support frame 11 to move upward, make the top plate 12 move upward, drive the mounting rack 14 to move upward, and move the steel structure parts out of the box body 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 reciprocate up and down again. When the slide plate 7 moves upward, make the fixed frame 20 move upward, drive the slider 23 to move upward, make the clamping block 26 move upward. When the clamping block 26 moves to the position of the positioning plate 30,The positioning plate 30 presses against the straight surface at the top of the clamping block 26. Under the limitation of the positioning plate 30, the clamping block 26 cannot move upward continuously, and thus the slider 23 cannot move upward continuously. 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 together, causing the hot air pump 33 to start and blow out hot air. The hot air blows obliquely downward to keep warm the steel structure parts moving upward. Along with the upward movement of the steel structure parts and in coordination with the downward-blowing hot air, it is convenient to blow the excess zinc liquid adhered to the surface of the steel structure parts downward, enabling the excess zinc liquid to slide downward along the surface of the steel structure parts and fall back into the box body 1 again. Thus, not only the excess zinc liquid on the surface of the steel structure parts is cleaned, but also the zinc liquid can be recycled, avoiding waste of the zinc liquid. The hot air is wrapped by the provided sleeve box 32 to prevent the blown hot air from dispersing quickly. When the hot air flows downward, under the guidance of the inclined surface at the top of the diversion block 34, the hot air can impact on the steel structure parts, achieving a better heat preservation effect for the steel structure parts, preventing the steel structure parts from cooling too quickly, and being able to better clean the zinc liquid on the surface of the steel structure parts. When moving the steel structure parts upward and cleaning the zinc liquid, through the cooperation of the convex block 18 and the push plate 19, the steel structure parts are shaken left and right again to prevent zinc liquid from remaining at the position where the steel structure parts are in contact with the pulley 16. When the sliding 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. The insertion plate 29 is inserted into the slider 23 along the empty slot and presses against the inclined slot 28 at the bottom of the clamping block 26. Under the extrusion of the insertion plate 29, the clamping block 26 moves into the slider 23, compressing the third spring 27. After the clamping block 26 moves and separates from the positioning plate 30, without the limitation of the positioning plate 30, under the action of the second spring 22, the slider 23 quickly moves upward and resets, causing the second contact 25 to separate from the first contact 24. Thus, the zinc liquid on the surface of the steel structure parts is always blown to the bottom of the steel structure parts. Subsequently, control the sliding plate 7 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 extrusion of the positioning plate 30, the clamping block 26 moves into the slider 23 again, compressing the third spring 27. When the slider 23 moves below the positioning plate 30, under the action of the third spring 27, the clamping block 26 resets, facilitating the hot air pump 33 to blow out hot air when controlling the steel structure parts to move upward next time.,
