DETAILED DESCRIPTION
[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0022] like Figure 1 - Figure 4 As shown, a rolling mill roll that is easy to disassemble includes a base 1, a disassembly mechanism 2, a driving mechanism 3 and a roll body 4, the driving mechanism 3 is fixedly connected to the upper surface of the base 1, the disassembly mechanism 2 is slidably connected to the upper surface of the base 1, and the two ends of the roll body 4 are rotatably connected to the outer surfaces of the disassembly mechanism 2 and the driving mechanism 3 respectively, the disassembly mechanism 2 includes a support frame 203 slidably connected to the upper surface of the base 1, the outer surface of the support frame 203 is rotatably connected to a support block 208, the support block 208 is arranged below the roll body 4, and the lower surface of the base 1 is fixedly connected to a first reduction motor 2 06, the output shaft of the first reduction motor 206 is fixedly connected with a threaded rod 205, the outer surface of the threaded rod 205 is meshed with the outer surface of the support frame 203, the disassembly mechanism 2 also includes a fixed plate 207 fixedly connected to the upper surface of the base 1, the outer surface of the fixed plate 207 is fixedly connected with a first hydraulic telescopic rod 201, the output end of the first hydraulic telescopic rod 201 is fixedly connected with a sliding frame 204, and the outer surface of the fixed plate 207 is fixedly connected with a central controller 202, by starting the first hydraulic telescopic rod 201, the sliding frame 204 and the roller body 4 can be separated.
[0023] In order to facilitate the disassembly of the rolling mill, a gap is left between the outer surface of the support frame 203 and the outer surface of the rolling mill body 4, and a sliding block 209 is fixedly connected to the side surface of the support frame 203, and the sliding block 209 is slidably connected to the upper surface of the base 1. A through hole is opened on the upper surface of the base 1, wherein the lower end of the support frame 203 passes through the through hole and is threadedly connected to the threaded rod 205. The sliding block 209 can increase the contact area between the support frame 203 and the upper surface of the base 1, thereby facilitating the support of the two groups of rolling mill bodies 4. The gap can reduce the wear of the support frame 203 on the rolling mill body 4. At the same time, the support frame 203 and the support block 208 facilitate the support of the two groups of rolling mill bodies 4.
[0024] It is worth mentioning that the output end of the first hydraulic telescopic rod 201 drives the sliding frame 204 to slide on the upper surface of the base 1, so that one end of the roller body 4 is separated from the first lifting frame 304 and the sliding frame 204, and then the first reduction motor 206 is started to separate the other end of the roller body 4 from the fixed frame 302 and the second lifting frame 305, so as to facilitate the separation of the roller body 4 and the bearing seat 308, so that the outer surface of the roller body 4 is respectively fitted with the outer surface of the support frame 203 and the support block 208, and then an external crane is used to set the sling on both ends of the roller body 4. When the roller body 4 at the bottom moves upward, the outer surface of the roller body 4 is squeezed against the outer surface of the support block 208, so that the support block 208 rotates on the outer surface of the support frame 203, thereby facilitating the disassembly of the bottom roller body 4.
[0025] There is a gap between the outer surface of the support frame 203 and the outer surface of the roller body 4, and the side surface of the support frame 203 is fixedly connected with a sliding block 209, and the sliding block 209 is slidably connected to the upper surface of the base 1. A through hole is opened on the upper surface of the base 1, wherein the lower end of the support frame 203 passes through the through hole and is threadedly connected to the threaded rod 205. The sliding block 209 can increase the contact area between the support frame 203 and the upper surface of the base 1, thereby facilitating the support of the two groups of roller bodies 4. The gap can reduce the wear of the support frame 203 on the roller body 4. At the same time, the support frame 203 and the support block 208 facilitate the support of the two groups of roller bodies 4.
[0026] In order to process raw materials of different thicknesses, the driving mechanism 3 includes a fixed frame 302 fixedly connected to the upper surface of the base 1, the inner wall of the fixed frame 302 is fixedly connected to the second hydraulic telescopic rod 303, the output end of the second hydraulic telescopic rod 303 is fixedly connected to the second lifting frame 305, and the outer surfaces of the second hydraulic telescopic rod 303 and the second lifting frame 305 are fixedly connected to the bearing seat 308.
[0027] The inner wall of the sliding frame 204 is fixedly connected to the outer surfaces of the other two groups of second hydraulic telescopic rods 303, and the output end of the second hydraulic telescopic rod 303 is fixedly connected to the first lifting frame 304. The inner walls of the first lifting frame 304 and the sliding frame 204 are fixedly connected to the outer surface of the bearing seat 308. Through multiple groups of bearing seats 308, it is convenient to increase the lubrication degree of the roller body 4 and reduce the occurrence of wear on the roller body 4. The outer surfaces of the fixed frame 302 and the second lifting frame 305 are fixedly connected to the second reduction motor 301, and the output shafts of the second reduction motor 301 are fixedly connected to the connecting shaft 307. The outer surface of the connecting shaft 307 is slidably connected to the roller body 4. The groove formed on the outer surface of the roller body 4 facilitates separation of the roller body 4 and the connecting shaft 307. By starting the second reduction motor 301, the output shaft of the second reduction motor 301 drives the connecting shaft 307 to rotate, and the rotation of the connecting shaft 307 drives the roller body 4 to rotate. The inner walls of the first lifting frame 304 and the sliding frame 204 are fixedly connected with a fixing protrusion 306. The outer surface of the fixing protrusion 306 is rotatably connected to the other end of the roller body 4. The fixing protrusion 306 facilitates support of one end of the roller body 4, so that a gap is formed between one end of the roller body 4 and the inner walls of the first lifting frame 304 and the sliding frame 204, thereby reducing the wear of the roller body 4.
[0028] Working principle: By starting the first hydraulic telescopic rod 201, the output end of the first hydraulic telescopic rod 201 drives the sliding frame 204 to slide on the upper surface of the base 1, and the sliding frame 204 slides to drive the first lifting frame 304 to slide, thereby separating one end of the roller body 4 from the bearing seat 308, and then starting the first reduction motor 206, the output shaft of the first reduction motor 206 drives the threaded rod 205 to rotate, and the rotation of the threaded rod 205 drives the two groups of support frames 203 to slide toward the fixed plate 207 at the same time, and the sliding of the support frame 203 pushes the roller body 4 to slide toward the fixed plate 207, thereby separating the other end of the roller body 4 from the fixed frame 302 and the second lifting frame 305, so as to facilitate the separation of the roller body 4 and the bearing seat 308. The outer surfaces of the roller body 4 are respectively fitted with the outer surfaces of the support frame 203 and the support block 208, and then an external crane is used to set the slings on the two ends of the roller body 4. When the roller body 4 at the bottom moves upward, the outer surface of the roller body 4 is squeezed against the outer surface of the support block 208, so that the support block 208 rotates on the outer surface of the support frame 203, thereby facilitating the disassembly of the roller body 4 at the bottom, and facilitating the disassembly of the roller body 4 to a certain extent. By starting the second hydraulic telescopic rod 303, the output end of the second hydraulic telescopic rod 303 drives the second lifting frame 305 and the first lifting frame 304 to move up and down, thereby facilitating the adjustment of the spacing of the roller body 4, so that the roller body 4 can process raw materials of different thicknesses.
