Description

Technical Field

[0001] This invention relates to the field of cold steel suspension technology, and in particular to a cold steel suspension device. Background Technology

[0002] Cold rolling is an important metal processing technology that applies pressure to metal materials at room temperature, causing plastic deformation to achieve the desired thickness, shape, and properties. Cold rolling is particularly important in the production of stainless steel strip because it not only significantly improves the strength, hardness, and surface finish of the stainless steel strip, but also optimizes the material's microstructure and mechanical properties through precise control of the deformation process.

[0003] A patent with publication number CN119734099A discloses a steel strip edge trimming device for cold rolling of stainless steel strip, including a base, mounting plates, a suspension frame, and a first guide roller. Mounting plates are connected to the top left and right sides of the base, and a suspension frame is connected between the two mounting plates. The first guide roller is rotatably connected to the lower end of the suspension frame. The device also includes sliding components, a second guide roller, a cutting mechanism, a grinding mechanism, and a cutting-off mechanism. Multiple sliding components are slidably connected to the suspension frame, and the lower ends of the sliding components are rotatably connected to the second guide roller. A cutting mechanism for trimming the stainless steel strip edge is located on the mounting plate in front of the suspension frame, and a grinding mechanism for grinding the cut edges of the stainless steel strip is located behind the suspension frame. A cutting assembly for processing stainless steel strip cutting waste is located below the cutting mechanism. Through the position-adjustable cutting roller and the third guide roller, precise cutting of the stainless steel strip edge is achieved, completing the edge trimming work.

[0004] In the steel production process, the electric arc furnace is an important piece of equipment for smelting metal. When cold steel is suspended on the furnace wall, it has a certain impact on the steel output and operation. Molten steel will adhere to the inner wall of the molten steel tank. As the thickness of the molten steel increases, the thickness of the inner wall of the molten steel tank will also increase, resulting in a continuous increase in the weight of the molten steel tank and a decrease in the amount of molten steel filled inside. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the problem that in the prior art, molten steel increases the thickness of the inner wall of the molten steel tank, resulting in a continuous increase in the weight of the molten steel tank, and the amount of molten steel filled inside is reduced, making it difficult to clean the cold steel on the inner wall of the molten steel tank later.

[0006] To solve the above-mentioned technical problems, the present invention provides a cold steel suspension device, including a gantry support frame and a swing arm disposed on the inner wall of the gantry support frame, and a molten steel tank disposed on the inner wall of the gantry support frame. A motor is fixedly installed on one end of the swing arm, and the outer surface of the motor is fixedly installed on the outer surface of the gantry support frame. A support column is fixedly installed on the outer surface of the other end of the swing arm. A motor is fixedly installed on one end of the support column. A hydraulic rod is fixedly connected to the output end of the motor. A small liquid pump is fixedly connected to the output end of the hydraulic rod. A scraper is fixedly connected to the output end of the small liquid pump, and the outer surface of the scraper movably overlaps the inner wall of the molten steel tank.

[0007] In one embodiment of the present invention, a limiting slot is formed on the inner wall of the gantry support frame, and a rope coiler is fixedly installed on the bottom inner wall of the gantry support frame at the two side edges.

[0008] In one embodiment of the present invention, a tension steel wire rope is fixedly connected to the output end of the rope coiler, and a limit frame is fixedly connected to the bottom inner wall of the gantry support frame.

[0009] In one embodiment of the present invention, a limiting rod is movably sleeved on the inner wall of the limiting frame, and a sealing cover is fixedly connected to the bottom end of the limiting rod.

[0010] In one embodiment of the present invention, the outer surface of the sealing cover is movably overlapped with the inner wall of the top of the molten steel tank, and the outer surface of the limiting rod is movably sleeved on the inner wall of the limiting slot.

[0011] In one embodiment of the present invention, protective sleeves are movably fitted on the inner walls of both sides of the bottom of the gantry support frame, and the outer surface of the molten steel tank is detachably installed on the inner wall of the protective sleeves.

[0012] In one embodiment of the present invention, a steel chain is fixedly connected to the outer surface of the protective collar, and a hollow box is fixedly connected to the other end of the steel chain.

[0013] In one embodiment of the present invention, a closed cover is provided on the top surface of the hollow box, and a circulating water tank is fixedly installed on the bottom surface of the hollow box and at the two side edges.

[0014] In one embodiment of the present invention, a circulating water pipe is fixedly connected to the output end of the circulating water tank, and the other end of the circulating water pipe extends to the inner wall of the hollow tank.

[0015] In one embodiment of the present invention, a counterweight body is provided on the inner wall of the hollow box, the counterweight body is located at the bottom edge of the molten steel tank, and a lifting hook is movably sleeved on the back of the protective sleeve.

[0016] The technical solution of the present invention has the following advantages compared with the prior art:

[0017] The present invention discloses a cold steel suspension device. After the molten steel inside the molten steel tank is cleaned out, leaving molten steel residue inside the molten steel tank, a pair of swing arms are rotated in conjunction with a motor. As the swing arms rotate, the support column on one end of the swing arm is inserted into the inside of the molten steel tank. At the same time, a pair of hydraulic rods are rotated in conjunction with a motor, and the scraper on the output end of the small liquid pump rotates on the inner wall of the molten steel tank, thereby scraping off and cleaning the cold steel residue inside the molten steel tank.

[0018] The cold steel suspension device of this invention, when the scraper is extended to the inlet of the molten steel tank by the contraction of the hydraulic rod, is extended by a small hydraulic pump so that the scraper initially overlaps the outer surface of the cold steel. Under the drive of the second motor, the cold steel is ground layer by layer. During the grinding, the scraper is extended by the hydraulic rod so that the scraper grinds the cold steel of the current thickness. After the current thickness is ground, the scraper is extended a second time by the small hydraulic pump to grind and clean the cold steel inside the molten steel tank a second time, so that the cold steel inside the molten steel tank is ground layer by layer.

[0019] The cold steel suspension device described in this invention prevents the steel chain from rotating along with the molten steel tank when the tank is tilted. Instead, the main body of the counterweight remains at the bottom edge of the tank, keeping the center of gravity of the tank at its lowest point. Simultaneously, a circulating water tank continuously pumps water into the circulating water pipes, allowing the water to circulate within the hollow tank. This reduces the surface temperature of the counterweight and the steel chain, preventing the high temperature inside the molten steel tank from being transferred to the surface of the steel chain through the protective ring, thus avoiding slight deformation of the steel chain due to high temperature.

[0020] The present invention discloses a cold steel suspension device. When the closed cover is moved open, it is engaged with the outer surface of the protective ring with the lifting hook. Under the pulling and lifting of the lifting hook, the protective ring is rotated around the surface of the gantry support frame, and the molten steel tank is tilted to pour out the molten steel inside the tank. After the molten steel inside the tank is poured out, the tank is rotated back and kept at a 45° tilt angle. At this time, the inside of the molten steel tank is cold steel polished with a scraper.

[0021] The present invention discloses a cold steel suspension device, which works in conjunction with a molten steel tank to fill and transport molten steel. The molten steel tank is moved to a suitable position by a gantry support frame. At this time, a rope coiler pulls the tension steel wire rope, causing the sealing cover to peel off from the top surface of the molten steel tank. When the sealing cover rises, a limiting rod slides on the inner wall of the limiting frame, allowing the limiting rod to pass through the inner wall of the limiting slot. The limiting slot and the limiting frame limit the position of the limiting rod, preventing the sealing cover from tilting during subsequent repositioning. Attached Figure Description

Detailed Implementation

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0033] Please see Figure 1 , Figure 3 , Figure 5 and Figure 8 The present invention provides a cold steel suspension device, including a gantry support frame 11 and a swing arm 12 disposed on the inner wall of the gantry support frame 11, and a molten steel tank 131 disposed on the inner wall of the gantry support frame 11. A motor 121 is fixedly installed on one end of the swing arm 12, and the outer surface of the motor 121 is fixedly installed on the outer surface of the gantry support frame 11. A support column 122 is fixedly installed on the outer surface of the other end of the swing arm 12. A motor 123 is fixedly installed on one end of the support column 122. A hydraulic rod 124 is fixedly connected to the output end of the motor 123. A small hydraulic pump 125 is fixedly connected to the output end of the hydraulic rod 124. A scraper 126 is fixedly connected to the output end of the small hydraulic pump 125, and the outer surface of the scraper 126 is movably attached to the inner wall of the molten steel tank 131.

[0034] After the molten steel inside the steel tank 131 is cleaned out, leaving molten steel residue inside the steel tank 131, the swing arm 12 is rotated by the motor 121. As the swing arm 12 rotates, the support column 122 on one end of the swing arm 12 is inserted into the inside of the steel tank 131. At the same time, the hydraulic rod 124 is rotated by the motor 123, and the scraper 126 on the output end of the small liquid pump 125 rotates on the inner wall of the steel tank 131, thereby scraping off and cleaning the cold steel residue inside the steel tank 131.

[0035] When the scraper 126 is extended to the inlet of the molten steel tank 131 by the retraction of the hydraulic rod 124, the scraper 126 is extended in conjunction with the small hydraulic pump 125, so that the scraper 126 initially overlaps the outer surface of the cold steel. Driven by the motor 123, the cold steel is ground layer by layer. While grinding, the scraper 126 is extended in conjunction with the hydraulic rod 124, so that the scraper 126 grinds the cold steel of the current thickness. After the current thickness is ground, the scraper 126 is extended a second time in conjunction with the small hydraulic pump 125, and the cold steel inside the molten steel tank 131 is ground and cleaned a second time, so that the cold steel inside the molten steel tank 131 is ground layer by layer.

[0036] Furthermore, such as Figure 1 and Figure 8As shown, a limiting slot 111 is formed on the inner wall of the gantry support frame 11. A rope coiler 112 is fixedly installed on the bottom inner wall of the gantry support frame 11, located at both edges. A tension steel wire rope 113 is fixedly connected to the output end of the rope coiler 112. A limiting frame 114 is fixedly connected to the bottom inner wall of the gantry support frame 11. A limiting rod 115 is movably sleeved on the inner wall of the limiting frame 114. A sealing cover 116 is fixedly connected to the bottom end of the limiting rod 115. The outer surface of the sealing cover 116 movably overlaps the top inner wall of the molten steel tank 131. The outer surface of the limiting rod 115 movably sleeves the inner wall of the limiting slot 111. Protective collars 13 are movably sleeved on the bottom inner walls of the gantry support frame 11. The outer surface of the protective sleeve 13 is detachably mounted on the inner wall of the protective sleeve 13. A steel chain 132 is fixedly connected to the outer surface of the protective sleeve 13. A hollow box 133 is fixedly connected to the other end of the steel chain 132. A closed cover 134 is provided on the top surface of the hollow box 133. A circulating water tank 136 is fixedly installed on the bottom surface of the hollow box 133 and at the two side edges. A circulating water pipe 137 is fixedly connected to the output end of the circulating water tank 136. The other end of the circulating water pipe 137 extends to the inner wall of the hollow box 133. A counterweight body 135 is provided on the inner wall of the hollow box 133. The counterweight body 135 is located at the bottom edge of the steel liquid tank 131. A lifting hook 138 is movably sleeved on the back of the protective sleeve 13.

[0037] The molten steel tank 131 is used to fill and transport molten steel, and the gantry support frame 11 moves the molten steel tank 131 to a suitable position. At this time, the rope coiler 112 pulls the tension steel wire rope 113, causing the sealing cover 116 to peel off from the top surface of the molten steel tank 131. When the sealing cover 116 rises, the limiting rod 115 slides on the inner wall of the limiting frame 114, so that the limiting rod 115 passes through the inner wall of the limiting slot 111. At this time, the limiting slot 111 and the limiting frame 114 limit the position of the limiting rod 115 to prevent the sealing cover 116 from tilting when it is put back later.

[0038] After the sealing cover 116 is moved open, it is fitted onto the outer surface of the protective collar 13 with the lifting hook 138. Under the pulling and lifting of the lifting hook 138, the protective collar 13 rotates around the surface of the gantry support frame 11, and the molten steel tank 131 is tilted, so that the molten steel inside the molten steel tank 131 is poured out. After the molten steel inside the molten steel tank 131 is poured out, the molten steel tank 131 is rotated and kept at a 45° tilt angle. Then, the scraper 126 is used to perform cold steel grinding on the inside of the molten steel tank 131.

[0039] When the gantry support frame 11 moves the molten steel tank 131, it works with multiple steel chains 132 to support and fix the hollow box 133. The main body 135 of the counterweight on the inner wall of the hollow box 133 keeps the hollow box 133 and the steel chains 132 in a downward state, so that the center of gravity of the molten steel tank 131 can be kept in a low state, so that there will be no excessive slight shaking when the molten steel tank 131 is filled and transported.

[0040] When the molten steel tank 131 is flipped, the steel chain 132, under the pull of the counterweight body 135, will not rotate with the rotation of the molten steel tank 131. At this time, the counterweight body 135 will remain at the bottom edge of the molten steel tank 131, keeping the center of gravity of the molten steel tank 131 at the lowest position. At the same time, in conjunction with the circulating water tank 136, water is poured into the circulating water pipe 137, so that the water circulates inside the hollow box 133, thereby reducing the surface temperature of the counterweight body 135 and the steel chain 132. This prevents the high temperature inside the molten steel tank 131 from being transmitted to the surface of the steel chain 132 through the protective ring 13, which could cause the steel chain 132 to deform slightly due to high temperature.

[0041] Working principle: The molten steel tank 131 is used to fill and transport molten steel. The gantry support frame 11 moves the molten steel tank 131 to a suitable position. At this time, the rope coiler 112 pulls the tension steel wire rope 113, causing the sealing cover 116 to peel off from the top surface of the molten steel tank 131. When the sealing cover 116 rises, the limiting rod 115 slides on the inner wall of the limiting frame 114, so that the limiting rod 115 passes through the inner wall of the limiting slot 111. At this time, the limiting slot 111 and the limiting frame 114 limit the position of the limiting rod 115 to prevent the sealing cover 116 from tilting when it is put back later.

[0042] After the sealing cover 116 is moved open, it is fitted onto the outer surface of the protective collar 13 with the lifting hook 138. Under the pulling and lifting of the lifting hook 138, the protective collar 13 rotates around the surface of the gantry support frame 11, and the molten steel tank 131 is tilted, so that the molten steel inside the molten steel tank 131 is poured out. After the molten steel inside the molten steel tank 131 is poured out, the molten steel tank 131 is rotated and kept at a 45° tilt angle. Then, the scraper 126 is used to perform cold steel grinding on the inside of the molten steel tank 131.

[0043] After the molten steel inside the steel tank 131 is cleaned out, leaving molten steel residue inside the steel tank 131, the swing arm 12 is rotated by the motor 121. As the swing arm 12 rotates, the support column 122 on one end of the swing arm 12 is inserted into the inside of the steel tank 131. At the same time, the hydraulic rod 124 is rotated by the motor 123, and the scraper 126 on the output end of the small liquid pump 125 rotates on the inner wall of the steel tank 131, thereby scraping off and cleaning the cold steel residue inside the steel tank 131.

[0044] When the scraper 126 is extended to the inlet of the molten steel tank 131 by the retraction of the hydraulic rod 124, the scraper 126 is extended in conjunction with the small hydraulic pump 125, so that the scraper 126 initially overlaps the outer surface of the cold steel. Under the drive of the motor 123, the cold steel is ground layer by layer. While grinding, the scraper 126 is extended in conjunction with the hydraulic rod 124, so that the scraper 126 grinds the cold steel of the current thickness. After the current thickness is ground, the scraper 126 is extended a second time in conjunction with the small hydraulic pump 125, and the cold steel inside the molten steel tank 131 is ground and cleaned a second time, so that the cold steel inside the molten steel tank 131 is ground layer by layer.

[0045] When the gantry support frame 11 moves the molten steel tank 131, it works with multiple steel chains 132 to support and fix the hollow box 133. The main body 135 of the counterweight on the inner wall of the hollow box 133 keeps the hollow box 133 and the steel chains 132 in a downward state, so that the center of gravity of the molten steel tank 131 can be kept in a low state, so that there will be no excessive slight shaking when the molten steel tank 131 is filled and transported.

[0046] When the molten steel tank 131 is flipped, the steel chain 132, under the pull of the counterweight body 135, will not rotate with the rotation of the molten steel tank 131. At this time, the counterweight body 135 will remain at the bottom edge of the molten steel tank 131, keeping the center of gravity of the molten steel tank 131 at the lowest position. At the same time, in conjunction with the circulating water tank 136, water is poured into the circulating water pipe 137, so that the water circulates inside the hollow box 133, thereby reducing the surface temperature of the counterweight body 135 and the steel chain 132. This prevents the high temperature inside the molten steel tank 131 from being transmitted to the surface of the steel chain 132 through the protective ring 13, which could cause the steel chain 132 to deform slightly due to high temperature.

[0047] Obviously, the above embodiments are merely illustrative examples for clarity and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
