Description

Technical Field

[0001] The present invention relates to the technical field of roll changing devices, and particularly to a mobile and adjustable roll changing workbench device. Background Art

[0002] Most of the domestic continuous casting and rolling copper rod production lines are the CR3500 continuous casting and rolling copper rod production lines of SMS Meer Company. Its product is Φ8 copper rod. The rolling mill part of this production line has 12 individually driven stands. The roll rings of the first 6 stands have a diameter of 360 mm. The upper and lower rolls of all stands are symmetrically adjusted. There are 12 rolls in total on these 6 stands, and their weights are all about 60 kg. The symmetric rolls in the stands are arranged in two ways: vertical and horizontal.

[0003] The existing Chinese patent with the publication number of CN215391600U discloses a hydraulic transverse movement device for roll group replacement of a rolling mill. By adopting a limit chute, a clamping mechanism, fastening screws, a moving trolley, and a fixed sleeve, during actual use, the device is installed above the limit chute, and the movement range of the device can be restricted through the limit chute to prevent large displacements during use and cause deviations in replacement. Moreover, the device can fix the hydraulic cylinder through the fixed sleeve;

[0033] Through the above technical solution, the electromagnet two 12 is then activated, causing the electromagnet one 11 and the electromagnet two 12 to generate magnetic forces simultaneously and balance each other. At this time, the gear ring 13 will be located in the middle of the transmission gear 10 and engage with the rack 14 for transmission; similarly, the motor 9 is activated, and the output shaft of the motor 9 drives the gear ring 13 to rotate through the transmission gear 10, and through the meshing action of the gear ring 13 and the rack 14, the housing 6 drives the vertical roller to displace and feed; at the same time, the hydraulic lifter 1 is activated for height adjustment.

[0034] Specifically, the horizontal roller clamping mechanism includes a first rotating shaft 15 arranged below the motor 9.

The transmission column 24 is slidably connected inside the limiting groove 23. Multiple groups of the limiting groove 23, the transmission groove 22, the transmission column 24 and the clamping plate 25 are correspondingly arranged and are dispersedly arranged in a ring shape.

[0035] Through the above technical solution, when it is necessary to load the horizontal roll, place the horizontal roll on the fixed disk 21 on the support plate 18. Secondly, start the electromagnet two 12, so that the electromagnet two 12 transmits magnetic force and magnetically attracts the toothed ring 13, making the toothed ring 13 approach the electromagnet two 12 and meshing with the gear one 16 on the rotating shaft one 15 for transmission; Similarly, start the motor 9, so that the output shaft of the motor 9 drives the toothed ring 13 to rotate through the transmission teeth 10, and through the meshing transmission of the toothed ring 13 and the gear one 16, the rotating shaft one 15 drives the gear two 17 for transmission, and the gear two 17 meshes with the toothed disk 19 for transmission, and the toothed disk 19 will rotate. The toothed disk 19 drives the transmission column 24 to perform synchronous displacement through the transmission groove 22 opened at the upper end. The transmission column 24 is slidably connected inside the limit groove 23, and the limit groove 23 guides the displacement direction of the transmission column 24, so that the transmission column 24 drives the clamping plate 25 to displace towards the horizontal roll. Multiple groups of clamping plates 25 cooperate with each other to clamp and fix the horizontal roll; Subsequently, start the electromagnet one 11, so that the electromagnet one 11 and the electromagnet two 12 generate magnetic force at the same time and balance each other. At this time, the toothed ring 13 will be located in the middle of the transmission teeth 10 and mesh with the rack 14 for transmission. Similarly, start the motor 9, so that the output shaft of the motor 9 drives the toothed ring 13 to rotate through the transmission teeth 10, and through the meshing of the toothed ring 13 and the rack 14, the housing 6 drives the horizontal roll to displace and load, and at the same time start the hydraulic lifter 1 for height adjustment

[0036] Specifically, the vertical roll clamping mechanism includes a gear three 27 arranged at the rear side inside the housing 6. The rear end of the gear three 27 is fixedly installed with a rotating shaft three 26. The lower side of the rear end of the housing 6 is fixedly installed with a support plate two 28. The rear side of the upper end of the support plate two 28 is fixedly installed with a support member 30. The inside of the support member 30 is rotatably connected with a bidirectional threaded rod 29. The rotating shaft three 26 penetrates through the housing 6 and extends to be fixedly connected with the bidirectional threaded rod 29. The vertical roll clamping mechanism further includes threaded sleeves 31 screw-driven on the front side and the rear side of the outer surface of the bidirectional threaded rod 29. The upper end of the threaded sleeve 31 is fixedly installed with a support column 32. The inner side of the support column 32 is fixedly installed with a clamping disk 33. The upper end of the support plate two 28 is fixedly installed with a limiting member 34 corresponding to the clamping disk 33. The limiting member 34 and the bidirectional threaded rod 29 are arranged perpendicular to each other.

[0037] Through the above technical solution, first, the drive adjustment mechanism is adjusted according to the roll to be loaded and unloaded. When the vertical roll needs to be replaced, the vertical roll is placed on the limiting member 34 on the second support plate 28. Subsequently, the first electromagnet 11 is activated to generate a magnetic force. The inner part of the toothed ring 13 contains a magnet, and under the influence of the magnetic adsorption, it approaches the first electromagnet 11 and meshes with the third gear 27 on the third rotating shaft 26 for transmission. Then, the motor 9 is started to make the output shaft of the motor 9 drive the transmission tooth 10 to rotate. The toothed ring 13 meshes with the transmission tooth 10 through the tooth grooves opened on the inner side, and further makes the transmission tooth 10 drive the toothed ring 13 to rotate. The toothed ring 13 meshes with the third gear 27 for transmission, so that the third rotating shaft 26 drives the bidirectional threaded rod 29 to rotate. When the bidirectional threaded rod 29 rotates, it drives the two threaded sleeves 31 that are helically connected to the outer surface, and the threaded sleeve 31 drives the clamping disc 33 to approach the vertical roll through the support column 32 and clamp and fix the vertical roll to prevent it from falling.

[0038] When the present invention is in use, first, the transmission adjustment mechanism is adjusted according to the rolls to be loaded and unloaded. When the vertical roll needs to be replaced, the vertical roll is placed on the limiting member 34 on the second support plate 28. Subsequently, the first electromagnet 11 is activated to generate a magnetic force. The inner part of the toothed ring 13 contains a magnet. Affected by the magnetic adsorption, it approaches the first electromagnet 11 and meshes with the third gear 27 on the third rotating shaft 26 for transmission. Then, the motor 9 is started to make the output shaft of the motor 9 drive the transmission gear 10 to rotate. The toothed ring 13 meshes with the transmission gear 10 through the tooth grooves opened on the inner side, so that the transmission gear 10 drives the toothed ring 13 to rotate. The toothed ring 13 meshes with the third gear 27 to make the third rotating shaft 26 drive the bidirectional threaded rod 29 to rotate. When the bidirectional threaded rod 29 rotates, it drives the two threaded sleeves 31 that are helically connected to the outer surface, so that the threaded sleeves 31 drive the clamping disc 33 to approach the vertical roll through the support columns 32 and clamp and fix the vertical roll to prevent it from falling. Subsequently, the second electromagnet 12 is activated to make the first electromagnet 11 and the second electromagnet 12 generate magnetic forces simultaneously and balance each other. At this time, the toothed ring 13 is located in the middle of the transmission gear 10 and meshes with the rack 14 for transmission. Similarly, the motor 9 is started to make the output shaft of the motor 9 drive the toothed ring 13 to rotate through the transmission gear 10, and through the meshing action of the toothed ring 13 and the rack 14, the housing 6 drives the vertical roll to perform displacement feeding. At the same time, the hydraulic lifter 1 is started for height adjustment. When the horizontal roll needs to be fed, the horizontal roll is placed on the fixed disc 21 on the first support plate 18. Secondly, by activating the second electromagnet 12, the second electromagnet 12 transmits a magnetic force and magnetizes the toothed ring 13, so that the toothed ring 13 approaches the second electromagnet 12 and meshes with the first gear 16 on the first rotating shaft 15 for transmission. Similarly, the motor 9 is started to make the output shaft of the motor 9 drive the toothed ring 13 to rotate through the transmission gear 10, and through the meshing transmission action of the toothed ring 13 and the first gear 16, the first rotating shaft 15 drives the second gear 17 to transmit. The second gear 17 meshes with the toothed disc 19 for transmission, and the toothed disc 19 will rotate. The toothed disc 19 drives the transmission column 24 to perform synchronous displacement through the action of the transmission groove 22 opened at the upper end. The transmission column 24 is slidably connected inside the limiting groove 23, and the limiting groove 23 guides the displacement direction of the transmission column 24, so that the transmission column 24 drives the clamping plate 25 to displace towards the horizontal roll. Multiple clamping plates 25 cooperate with each other to clamp and fix the horizontal roll. Similarly, subsequently, the first electromagnet 11 is activated to make the first electromagnet 11 and the second electromagnet 12 generate magnetic forces simultaneously and balance each other. At this time, the toothed ring 13 is located in the middle of the transmission gear 10 and meshes with the rack 14 for transmission. Similarly, the motor 9 is started to make the output shaft of the motor 9 drive the toothed ring 13 to rotate through the transmission gear 10, and through the meshing action of the toothed ring 13 and the rack 14, the housing 6 drives the horizontal roll to perform displacement feeding. At the same time, the hydraulic lifter 1 is started for height adjustment.
