Description

Technical Field

[0001] This invention relates to the field of metal rolling processing technology, specifically to a support roller loading and unloading auxiliary device. Background Technology

[0002] The existing 20-roll mill has a wide range of applications. With its unique multi-roll structure, it can achieve high-precision rolling operations, thereby significantly improving the flatness and precision of metal materials such as strip steel. This is of vital importance to many industries that rely on high-quality metal sheets, such as automobile manufacturing and electronic equipment production.

[0003] In recent years, with the increasing demands for the quality of metal materials in industrial production, the performance optimization and stable operation of 20-roll mills have become a focus of continuous attention in the industry. Existing 20-roll mills are generally equipped with eight rear support rolls and six intermediate rolls (two adjacent rolls). The rear support rolls are located on the outermost side, while the two intermediate rolls are adjacent to them.

[0004] When the rolling mill is in daily use, the rear support roll and the two intermediate rolls typically withstand a maximum pressure of up to 800 tons. This significant pressure inevitably causes wear between them. Furthermore, if a strip breakage occurs during rolling, the surfaces of the rear support roll and the two intermediate rolls will suffer further damage. If pits appear on the surface of the rear support roll, under continuous pressure, pits will gradually form on the surface of the two intermediate rolls as well. Similarly, these pits will be transferred to the surface of the strip, affecting processing quality. However, the rear support roll and the two intermediate rolls are quite heavy. When replacement is needed, the entire replacement process not only consumes a large amount of manpower and material resources but also leads to prolonged mill downtime, disrupting normal production and significantly reducing production efficiency. Therefore, to address the problems existing in the replacement of roll structures in existing 20-roll rolling mills, the applicant seeks to provide a support roll loading and unloading auxiliary device.

[0021] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-5A support roller loading and unloading auxiliary device includes a mounting column 2 and a hoisting assembly set on the top of the mounting column 2. The hoisting assembly includes a central control panel 3, a sling assembly 4, and a hoisting roller assembly 5. The hoisting roller assembly 5 consists of a support frame plate and hoisting rollers fitted inside the top of the support frame plate. The bottom of the support frame plate is fixed to the top of the central control panel 3. One side of the sling assembly 4 is fitted in the gap between the support frame plate and the hoisting roller structure, thereby enabling subsequent hoisting use with the existing cable trolley 1 and meeting the lifting and displacement requirements of the overall device. A counterweight 9 is slidably mounted on the outer side of the mounting column 2, and a slide rail 11 fixed to the surface of the mounting column 2 is engaged inside the counterweight 9. A gear and toothed plate transmission mechanism is provided on the outer side of the middle part of the mounting column 2, which can transmit power to the counterweight 9 and make the counterweight 9 reciprocate linearly. The gear transmission mechanism includes a straight gear plate frame 10, a dual-shaft motor 15, and a gear assembly whose output end is connected to the dual-shaft motor 15. The straight gear plate frame 10 is fixedly nested in the middle of the counterweight block 9 and meshes with the gear assembly for transmission. The inner wall of the counterweight 9 is provided with a clearance groove. The gear assembly includes an I-shaped gear shaft 13 and two T-shaped gear shafts 14. The end diameter of the T-shaped gear shaft 14 is smaller than that of the I-shaped gear shaft 13. The outer side of the dual-axis motor 15 is fitted with a transmission bracket 12 that passes through the clearance groove and is fixed to the bottom surface of the mounting column 2. The two ends of the I-shaped gear shaft 13 are respectively fitted into the front and rear ends of the bottom of the transmission bracket 12. A fixing seat is installed between the surface of the dual-axis motor 15 housing and the top inner wall of the transmission bracket 12. The two T-shaped gear shafts 14 are respectively connected to the two output ends of the dual-axis motor 15. The top of the end of the I-shaped gear shaft 13 is meshed with the corresponding T-shaped gear shaft 14. The bottom of the end of the I-shaped gear shaft 13 is meshed with the corresponding side of the straight tooth plate frame 10. A connector 6 and a roller component 7 are provided on the top side of the mounting column 2. One end of the roller component 7 is fitted with one end of the connector 6, and a locking component 8 for fixed connection is provided at the fitting point between the connector 6 and the roller component 7. One end of the roller body component 7 and one end of the connector 6 are respectively provided with a clearance through hole and an I-shaped through hole. After one end of the roller body component 7 is fitted into one end of the connector 6, the clearance through hole is located in the middle of the I-shaped through hole and aligned, thereby providing a clearance channel for assembly limiting. The locking component 8 includes a limiting rod 81. One end of the limiting rod 81 passes through the front end of the I-shaped through hole, the clearance through hole, and the rear end of the I-shaped through hole and protrudes outward. Both ends of the limiting rod 81 are provided with external threads, and both ends of the limiting rod 81 are threadedly connected with long nuts 82. The two long nuts 82 in the opposite position can clamp and limit the connection head 6 and roller component 7 in the set during the spiral locking process with the limiting rod 81, thereby ensuring the stability during the subsequent replacement of roller component 7.

[0023] When in use, for the roller component 7 to be replaced and installed, firstly, fit one end of the roller component 7 into the preset space inside one end of the connector 6 until the through hole and the I-shaped through hole are aligned and connected to form a limiting space. Then, insert one end of the limiting rod 81 through the limiting space until both ends of the rod are placed on the outside of the roller component 7. After completion, use two long nuts 82 to thread them onto the limiting rod 81 and use a wrench to clamp and limit the fitting of the connector 6 and the roller component 7 at the two long nuts 82 in the opposite position to ensure the stability of the assembly of the connector 6 and the roller component 7. After the roller component 7 is installed, the existing cable trolley 1 is used to connect the lifting assembly, the mounting column 2, and related devices to the loading and unloading auxiliary device for hoisting. After completion, the cable trolley 1, through the lifting assembly, drives the loading and unloading auxiliary device and the roller component 7 to move up and down and horizontally. Once it reaches the preset position, considering the actual gravity, the roller component 7 should be in a relatively tilted state relative to the horizontal plane. To restore the roller component 7 to a horizontal state, the dual-shaft motor 15 is started. The two output ends of the dual-shaft motor 15 are respectively connected to their corresponding T-shaped gear shafts 14, thereby causing the two... T-shaped gear shaft 14 synchronously meshes with both ends of I-shaped gear shaft 13 until I-shaped gear shaft 13 meshes with spur gear frame 10, causing spur gear frame 10 to drive counterweight 9 to slide back and forth on the outside of mounting column 2, thereby changing the center of gravity of the entire device until roller component 7 returns to a horizontal state. After completion, continue to start cable trolley 1 to fill and install the horizontal roller component 7 in the corresponding position. After completion, turn the two long nuts 82 and separate the two long nuts 82 from the limit rod 81. Then, take out the limit rod 81 and reset it by driving the loading and unloading auxiliary device through cable trolley 1. For roller components 7 that need to be removed from the corresponding equipment due to wear, the operation steps are similar to those described above. The existing cable trolley 1 is used for hoisting and connection via a hoisting assembly, mounting column 2, and related devices forming a loading and unloading auxiliary device. After completion, the cable trolley 1 drives the loading and unloading auxiliary device to move up and down and horizontally through the hoisting assembly. Once the preset position is reached, considering the actual gravity, the connector 6 should be in a relatively tilted state relative to the horizontal plane. To restore the horizontal state of the connector 6, the dual-axis motor 15 is started. The two output ends of the dual-axis motor 15 are respectively connected to their corresponding T-shaped gear shafts 14, causing the two T-shaped gear shafts 14 to synchronously mesh with the two ends of the I-shaped gear shaft 13 until the I-shaped gear shaft 13 meshes with the straight gear plate frame 10, causing the straight gear plate frame 10 to... The counterweight 9 is slid back and forth on the outside of the mounting column 2, thereby changing the center of gravity of the entire device until the connector 6 returns to a horizontal state. After completion, the cable trolley 1 is activated to fit the horizontal connector 6 with one end of the roller component 7 until the through hole and the I-shaped through hole are aligned and form a limiting space. Then, one end of the limiting rod 81 is inserted through the limiting space until both ends are placed on the outside of the roller component 7. After completion, two long nuts 82 are threaded to the limiting rod 81, and a wrench is used to clamp and limit the fitting of the connector 6 and the roller component 7 at the two long nuts 82 in opposite positions, ensuring the stability of the assembly of the connector 6 and the roller component 7. After completion, the cable trolley 1 drives the loading and unloading auxiliary device and the roller component 7 to automatically move and lift and disassemble.

[0024] Please see Figures 1-2 The outer side of the straight gear plate frame 10 is fitted with a protective component 16. The protective component 16 includes a U-shaped frame, in which a protective filter is nested and fixed. There is clearance space between the protective filter and the straight gear plate frame 10, the I-shaped gear shaft 13, and the T-shaped gear shaft 14 to avoid structural interference.

[0025] During use, considering that dust in the environment may have an adverse effect on the gear and sprocket transmission mechanism, protective component 16 is used to cover the outside of the gear and sprocket transmission mechanism. This provides dust prevention and ventilation without interfering with the operation of the gear and sprocket transmission mechanism, thus fully ensuring the service life of the gear and sprocket transmission mechanism.

[0026] Please see Figures 1-2An electrical control cabinet 18 is mounted on the surface of the central control unit 3. The electrical control cabinet 18 and the top horizontal plane of the mounting column 2 are arranged perpendicular to each other. A balanced gyroscope is installed inside the electrical control cabinet 18 to meet the real-time horizontal detection of the entire device. A controller is installed inside the electrical control cabinet 18, and the controller is electrically connected to an elastic wire 19. The structure of the elastic wire 19 can reciprocate or retract and reset. The end of the elastic wire 19 away from the electrical control cabinet 18 is electrically connected to a remote control handle 20.

[0027] In use, considering the need for remote control of the gear and toothed plate transmission mechanism during operation, a medium-to-long-range control condition is formed by setting an elastic wire 19 and a remote control handle 20. The elastic wire 19 is a retractable structure that can meet the needs of people of different heights to operate the transmission bracket 12 while standing on the ground.

[0028] Please see Figures 5-8 A transition transmission assembly 17 is provided on the top of one side of the mounting column 2. The transition transmission assembly 17 includes a servo motor 171, a first gear 172, a second gear 173, and an outer protective box 174 fixed on the top of the mounting column 2. The other end of the connector 6 is fitted with one side wall of the servo motor 171 through a bearing and extends into the interior of the outer protective box 174. The first gear 172, the second gear 173, and the servo motor 171 are all movably fitted inside the outer protective box 174. The inner middle part of the first gear 172 and the inner middle part of the second gear 173 are respectively fitted with the other end of the connector 6 and connected to the output end of the servo motor 171. A mounting base is provided between the housing surface of the servo motor 171 and the inner wall of the outer protective box 174, and the servo motor 171 is electrically connected to the electrical control cabinet 18. The connector 6 can drive the roller component 7 to rotate synchronously under the meshing transmission of the first gear 172 and the second gear 173 driven by the servo motor 171.

[0029] In use, considering the alignment and assembly requirements of the non-cylindrical roller components, the transition transmission component 17 is used to rotate and adjust the connector 6 and roller component 7 in the assembled state. The specific operation is as follows: Turn on the servo motor 171, and the output end of the servo motor 171 drives the corresponding first gear 172, which in turn meshes with the second gear 173. Finally, the second gear 173 drives the connector 6 and the roller component 7 in the assembled state to rotate and adjust until the angle of the overall structure of the roller component 7 meets the installation and use requirements.

[0030] Please see Figures 5-9The connector 6 has a conical flow channel 24 in the middle that communicates with the space of one end of the connector. The output end of the servo motor 171 passes through the middle of the first gear 172, one side wall of the outer protective box 174 and extends to the outside of the outer protective box 174. A transition box 21 that can be fitted with the output end of the servo motor 171 is installed on one side of the outer protective box 174. The fan blade 22 fixed to the output end of the servo motor 171 is fitted inside the transition box 21. A metal air guide tube 23 is fitted inside the transition box 21. The other end of the connector 6 has several transition holes 25 that communicate with the space of the conical flow channel 24 along its circumference. The metal air guide tube 23 can be aligned with the corresponding transition holes 25 and guide the accelerated airflow generated by the servo motor 171 driving the fan blade 22 through the transition holes 25 to the inside of the conical flow channel 24. An air inlet is provided on the surface of the fan blade 22.

[0031] During use, considering that during the continuous use of the connector 6, the inner wall of its assembly space may be covered with debris, which may affect the subsequent assembly accuracy with the related roller components 7, the servo motor 171 can be started during the overall device maintenance process. The output end of the servo motor 171 drives the corresponding first gear 172, which in turn meshes with the second gear 173, and finally the second gear 173 drives the connector 6 to rotate synchronously. At the same time, the output of the servo motor 171 will drive the fan blade 22 to rotate back and forth inside the transition box 21, thereby generating an accelerated airflow inside the transition box 21 and guiding the accelerated airflow through the metal air guide tube 23 to the other end of the connector 6. Then, the airflow is guided into the conical flow channel 24 through the transition hole 25, which is periodically aligned with the open port of the metal air guide tube 23, and then rushes into the housing space inside the connector 6. In conjunction with the centrifugal force of the connector 6, the debris attached to the inner wall of the housing space of the connector 6 is cleaned twice.
