[0045] In the related art, counterweights are also provided on the hanging beam to adjust the overall center of gravity. However, the speed of adjusting and positioning the counterweights to quickly balance the center of gravity is not fast enough, which will also affect the disassembly and replacement of the furnace rolls and the efficiency of the disassembly and replacement of the furnace rolls.

[0046] The present application will be described below with reference to the accompanying drawings:

[0047] Figure 1 It is a schematic structural diagram of a counterweight balance device in some or certain embodiments provided by the present application. Figure 2 For Figure 1 the A-A cross-sectional view of, in combination with Figure 1 and Figure 2 the present application provides a counterweight balance device applied to assist in the disassembly and assembly of the furnace roll 100, including:

[0048] A hanging beam 1, with a connecting portion 11 for connecting the furnace roll 100 provided at one end, and a scale 12 extending along the length direction of the hanging beam 1 provided on one side.

[0049] A counterweight assembly 2, movably sleeved on the hanging beam 1 along the length direction and provided with a calibration portion 21 opposite to the scale 12.

[0050] A driving assembly 3, fixedly connected to the hanging beam 1 and provided with a driving member 31 movable along the length direction, and the driving member 31 is fixedly connected to the counterweight assembly 2.

[0051] If it is necessary to repair and replace the furnace rolls 100 of the continuous annealing furnace, a crane or lifting equipment can be used to connect with the lifting beam 1 through a sling such as a hook. One end of the lifting beam 1 is connected to the furnace roll 100 through the connecting part 11. The scale 12 arranged on one side of the lifting beam 1 and extending along its own length can cooperate with the counterweight assembly 2 sleeved on the lifting beam 1 and spaced apart from each other. The counterweight assembly 2 is movably sleeved on the lifting beam 1 along the length direction of the lifting beam 1. By moving the counterweight assembly 2 relative to the lifting beam 1 along the length direction of the lifting beam 1, the center of gravity of the overall counterweight balance device can be adjusted after being connected to the furnace roll 100, and the center of gravity balance of the furnace roll 100 during the lifting process can be controlled. Moreover, the counterweight assembly 2 is provided with a calibration part 21 opposite to the scale 12. During the process of moving the counterweight assembly 2, it is possible to judge whether the center of gravity of the counterweight balance device connected to the furnace roll 100 of a certain specification is stable through the calibration part 21 on the counterweight assembly 2 opposite to the scale 12. The balancing speed is fast, which is beneficial to improving the transfer and disassembly and replacement efficiency of the furnace roll 100. And a driving assembly 3 fixedly connected to the lifting beam 1 is provided in the counterweight balance device. The driving assembly 3 is provided with a driving member 31 that is movable along the length direction and fixedly connected to the counterweight assembly 2. The driving assembly 3 controls the movement of the driving member 31 to quickly level the counterweight assembly 2, which is also beneficial to improving the transfer and disassembly and replacement efficiency of the furnace roll 100, and solves the technical problem that the disassembly and replacement efficiency of the furnace roll 100 is not ideal to a certain extent.

[0052] For ease of understanding, the following can be provided Figure 3 and Figure 4 , Figure 3 is a schematic diagram of the no-load balance position of a counterweight balance device in some or certain embodiments provided by the present application. Figure 4 is a schematic diagram of the full-load balance position of a counterweight balance device in some or certain embodiments provided by the present application. Refer to Figure 3 and Figure 4 , it can be seen that when the counterweight balance device is in the full-load state connected with the furnace roll 100 and the no-load state not connected with the furnace roll 100, the counterweight assembly 2 is in different positions.

[0053] In some or certain embodiments, the counterweight assembly 2 includes:

[0054] A load-bearing frame 22, which is movably sleeved on the lifting beam 1 along the length direction and is provided with a calibration part 21 opposite to the scale 12.

[0055] A plurality of counterweight blocks 23, which are supported on the load-bearing frame 22.

[0056] A pointer, which is fixedly connected to the load-bearing frame 22 and is configured as the calibration part 21.

[0057] The load-bearing frame 22 can serve as the main structure for bearing weight and installing other components. It can be used to place multiple counterweight blocks 23. Adjusting the number of counterweight blocks 23 and the distance between the load-bearing frame 22 and the connecting part 11 on the suspension beam 1 can both adjust the center of gravity of the overall counterweight balance device. The adjustment of the center of gravity of the counterweight balance device is more flexible, and it can also be applicable to furnace rolls 100 of different specifications and weights, which is beneficial to improving the versatility of the counterweight assembly 2. A pointer fixedly connected to the load-bearing frame 22 is provided as the calibration part 21, and the measurement and positioning effects are better, which is beneficial to improving the disassembly, replacement and installation efficiency of the furnace roll 100.

[0058] In some embodiments, bumps or grooves can also be provided on the load-bearing frame 22 as the calibration part 21. This is also beneficial to improving the disassembly, replacement and installation efficiency of the furnace roll 100.

[0059] In some embodiments, structures or components such as the scale 12 that are connected to the suspension beam 1 and spaced from the counterweight assembly 2 can be connected to the suspension beam 1 by means of fasteners or welding. For structures or components such as the scale 12, through holes for passing through these structures can be provided on the load-bearing frame 22, or one end of the scale 12 can be fixedly connected to the suspension beam 1, and a spacing can be left between the body of the scale 12 and the suspension beam 1 for the load-bearing frame 22 to move; or the scale 12 and the load-bearing frame 22 can also be spaced, and the calibration part 21 of the scale 12 faces the scale 12 and there can be partial overlap in the orthographic projection on the horizontal plane; none of these will cause interference between the scale 12 and the counterweight assembly 2.

The outer diameter of the locking nut 223 threadedly connected to the other end of the rod part 222 is larger than the aperture of the through hole of the counterweight block 23, which can also increase the number of counterweight blocks 23 that can be connected on the load-bearing frame 22, so that the overall counterweight balance device can be applicable to furnace rolls 100 of larger specifications and weights, and improve the versatility of the counterweight balance device.

[0065] It should be noted that for the convenience of connecting the counterweight blocks 23, some of the counterweight blocks 23 are provided with through holes or perforations on their own, and some annular counterweight blocks 23 can also be sleeved on the rod portion 222 for counterweight.

[0066] In some embodiments, a plurality of mutually parallel rod portions 222 can be provided on the main body 221, and each rod portion 222 can be inserted into at least one counterweight block 23, or a plurality of rod portions 222 can be inserted into the same counterweight block 23 simultaneously.

[0067] In some embodiments, the rod portion 222 is provided at the bottom of the main body 221 of the load-bearing frame 22, and the counterweight balance device further includes a bracket 4 having the same height as the rod portion 222, and the bracket 4 is used to support one end of the suspension beam 1.

[0068] The rod portion 222 is provided at the bottom of the main body 221 of the load-bearing frame 22, and the counterweight balance device further includes a bracket 4 having the same height as the rod portion 222, which can be used to support one end of the suspension beam 1. Then, when the counterweight balance device is not needed, the counterweight block 23 can also be sleeved on the rod portion 222, so that the counterweight assembly 2 and the bracket 4 can be located at both ends of the suspension beam 1 respectively, playing a role in supporting and positioning the whole suspension beam 1, and reducing the possibility of damage to, for example, the driving structure and the scale 12 on the suspension beam 1 due to friction, and prolonging the overall service life of the counterweight balance device.

[0069] It should be noted that in this application, one end and the other end usually refer to one end or the other end in the length direction of the corresponding structure or component, one side or the other side usually refers to one side or the other side in the width direction of the structure or component, the bottom can be the lowest part of the corresponding structure or component when the counterweight balance device is in use, and the top can be the highest part of the corresponding structure or component when the counterweight balance device is in use.

[0070] In some embodiments, the drive assembly 3 can also be provided at the bottom of the suspension beam 1 and spaced from the counterweight assembly 2, with a high space utilization rate. The counterweight assembly 2 can also be configured to be composed of the load-bearing frame 22 and the counterweight blocks 23 placed inside the load-bearing frame 22. Similarly, the disassembly, installation and replacement efficiency of the furnace roll 100 can be improved.

[0074] At least two limit sensors 5, which are connected to the suspension beam 1 at intervals along the length direction of the suspension beam 1, and the counterweight assembly 2 is located between two adjacent limit sensors 5.

[0075] In some embodiments, the suspension beam 1 is provided with a strip-shaped protrusion 14 extending along its own length direction, and the limit sensor 5 is tightly fixed to the strip-shaped protrusion 14 through a fastener.
