[0020] Please refer to Figs. 1-3 The embodiment provides a technical scheme: a cold-rolled plate coil lifting appliance, which comprises a hanging seat 1 and a hoisting and fixing mechanism 5.
[0021] The hanging seat 1 is provided with a sliding groove one on the lower side, the inside of the sliding groove one is slidably connected with two symmetrically distributed moving frames 3, the opposite inner side surfaces of the two moving frames 3 are both provided with hollow columns 4, and the hanging seat 1 further comprises a single-chip microcomputer 2, the single-chip microcomputer 2 is located outside the hanging seat 1, the input end of the single-chip microcomputer 2 is electrically connected with an external power supply, a bidirectional screw 9 is rotatably connected in the inside of the sliding groove one through a bearing, the moving frames 3 are both threadedly connected with the bidirectional screw 9, the right side of the hanging seat 1 is provided with a driving motor 10, the input end of the driving motor 10 is electrically connected with the output end of the single-chip microcomputer 2, the output shaft of the driving motor 10 is fixedly connected with the right end of the bidirectional screw 9, and the upper middle part of the hanging seat 1 is provided with a lifting ring 11. When the lifting appliance is used to hoist the cold-rolled plate coil, first, the device is connected with an external hoisting unit by a rope through the lifting ring 11, when the cold-rolled plate coil is hoisted, the cold-rolled plate coil is located at the middle part of the opposite inner sides of the two hollow columns 4 through the external hoisting unit, then the single-chip microcomputer 2 starts the driving motor 10 to drive the output shaft to rotate the bidirectional screw 9, and the bidirectional screw 9 is threadedly connected to drive the two moving frames 3 to move close to the center part of the device along the sliding groove one.
[0022] The lifting fixing mechanism 5 comprises four slide grooves two 51, four circular sliding seats 52, four connecting shafts 53, four circular seats 54, four guide rods 55, four linkage seats 56 and four inner diameter supporting seats 57. The four slide grooves two 51 are respectively arranged on the outer side of the hollow column 4, and four slide grooves two 51 form a group. The circular sliding seat 52 is slidably connected between any two slide grooves two 51 in the group. The opposite inner side of the two circular sliding seats 52 is provided with the circular seat 54 through the connecting shaft 53. The outer side of the circular seat 54 is provided with the four evenly distributed guide rods 55. The outer side of the hollow column 4 is provided with the four evenly distributed slide grooves three. The end of the guide rod 55 away from the center of the hollow column 4 penetrates through the adjacent slide groove three and is slidably connected with the linkage seat 56. The end of the linkage seat 56 away from the center of the hollow column 4 is provided with the inner diameter supporting seat 57. The lifting fixing mechanism 5 further comprises the connecting seat 58 and the supporting rotating rod 59. The connecting seat 58 is evenly arranged on the inner arc surface of the inner diameter supporting seat 57 and the outer side of the hollow column 4. The supporting rotating rod 59 is rotatably connected between any two connecting seats 58 through the rotating shaft. The rubber pad 6 is arranged on the outer arc surface of the inner diameter supporting seat 57. The bottom end of the opposite inner side of the two moving frames 3 is fixedly connected with the outer surface of the adjacent circular sliding seat 52 through the telescopic column 7 and the spring 8. The spring 8 is movably sleeved with the outer end of the adjacent telescopic column 7. When the cold-rolled plate roll is lifted and fixed, the moving frame 3 drives the corresponding hollow column 4 into the inner circle of the cold-rolled plate roll. When the hollow column 4 is deeply inserted into the inner circle of the hollow column 4 to a certain extent, the circular sliding seat 52 contacts with the side surface of the cold-rolled plate roll. With the hollow column 4 continuing to deeply insert into the inner circle of the cold-rolled plate roll, the circular sliding seat 52 is limited by the contact of the side surface of the cold-rolled plate roll, and then slides along the slide groove two 51 to the end away from the center of the device. The telescopic end of the telescopic column 7 and the spring 8 are retracted. The circular sliding seat 52 drives the corresponding guide rod 55 to synchronously slide along the slide groove three through the connecting shaft 53 and the circular seat 54. The guide rod 55 slides along the slide groove three to the end away from the center of the device, and vertically and self-adaptingly slides and contacts with the corresponding linkage seat 56. The inner diameter supporting seat 57 moves to the end away from the center of the device. In this process, the inner diameter supporting seat 57 drives the corresponding supporting rotating rod 59 to self-adaptively rotate around the corresponding rotating shaft through the parallelogram formed by the corresponding two supporting rotating rods 59 on the inner diameter supporting seat 57, so that the inner diameter supporting seat 57 horizontally moves away from the center of the device and radially moves away from the center of the device. Thus, the four inner diameter supporting seats 57 on each side tightly fix the inner circle of the cold-rolled plate roll, and cooperate with the transverse limiting of the circular sliding seat 52 to completely fix the cold-rolled plate roll, so as to avoid the relative sliding phenomenon between the cold-rolled plate roll and the lifting device. The cold-rolled plate roll is firmly lifted. The rubber pad 6 increases the contact friction force between the inner diameter supporting seat 57 and the cold-rolled plate roll, and further avoids the relative sliding phenomenon between them. After the cold-rolled plate roll is lifted and fixed, the inner components of the lifting fixing mechanism 5 are restored to the initial state through the compression force of the spring 8, so as to prepare for the next lifting and fixing of the cold-rolled plate roll.The device can radially tighten and transversely limit the cold-rolled plate roll through the transmission element, so that relative shaking and abrasion between the cold-rolled plate roll and the lifting appliance during hoisting is avoided, and the cold-rolled plate roll is firmly hoisted by the lifting appliance.
[0023] The working principle of the cold-rolled plate roll lifting appliance is as follows: when the lifting appliance is used to hoist the cold-rolled plate roll, first, the device is connected with the external hoisting unit by a rope through the lifting ring 11, when the cold-rolled plate roll is hoisted, the cold-rolled plate roll is located at the middle part of the opposite inner sides of the two hollow columns 4 through the external hoisting unit, then the single-chip microcomputer 2 starts the driving motor 10 to drive the output shaft to rotate the bidirectional screw rod 9, the bidirectional screw rod 9 is connected through threads to drive the two moving frames 3 to move towards the center of the device along the sliding groove one, the moving frame 3 drives the corresponding hollow column 4 to enter the inner circle of the cold-rolled plate roll, when the hollow column 4 is deeply inserted into the inner circle of the hollow column 4 to a certain extent, the circular sliding seat 52 is in contact with the side surface of the cold-rolled plate roll, as the hollow column 4 continues to deeply insert into the inner circle of the cold-rolled plate roll, the circular sliding seat 52 is limited by the contact of the side surface of the cold-rolled plate roll, and thus the circular sliding seat 52 slides along the sliding groove two 51 to the end away from the center of the device, the telescopic end of the telescopic column 7 and the spring 8 are retracted, the circular sliding seat 52 drives the corresponding guide rod 55 to slide along the sliding groove three through the connecting shaft 53 and the circular seat 54, the guide rod 55 slides along the sliding groove three to the end away from the center of the device while vertically and adaptively sliding in contact with the corresponding linkage seat 56, the inner diameter tightening seat 57 moves to the end away from the center of the device, in this process, the inner diameter tightening seat 57 drives the corresponding support rotating rod 59 to adaptively rotate around the corresponding rotating shaft axis through the parallelogram formed by the two support rotating rods 59 on the inner diameter tightening seat 57, so that the inner diameter tightening seat 57 is horizontally away from the center of the device while being radially away from the center of the device, and thus the four inner diameter tightening seats 57 on each side fix and tighten the inner circle of the cold-rolled plate roll, and cooperate with the transverse limiting of the circular sliding seat 52, so that the cold-rolled plate roll is completely fixed, the relative sliding phenomenon between the cold-rolled plate roll and the lifting appliance is avoided, the cold-rolled plate roll is firmly hoisted, the contact friction force between the inner diameter tightening seat 57 and the cold-rolled plate roll is increased through the rubber pad 6, the relative sliding phenomenon between the two is further avoided, and after the cold-rolled plate roll is hoisted, the circular sliding seat 52 is separated, the compression elastic force of the spring 8 is used to restore each component in the hoisting and fixing mechanism 5 to the initial state, so as to prepare for the next hoisting and fixing of the cold-rolled plate roll.
[0024] It is worth noting that the single-chip microcomputer 2 disclosed in the above embodiment can adopt MSP430, the driving motor 10 can adopt Y90S-2, and the single-chip microcomputer 2 controls the driving motor 10 to work by using the method commonly used in the prior art.
