It should be understood that the figure mark also applies to other identical parts or components.

[0028] The embodiment of the present application provides a device for replacing roller bearings of a glass annealing furnace, which solves the problem that the rotation of the existing transition roller needs to be stopped when the bearing is replaced. The stopped transition roller is easy to bend and break the soft glass ribbon, causing the risk of glass breakage.

[0029] refer to Figure 1 and Figure 2 The device for replacing roller bearings of a glass annealing furnace provided in an embodiment of the present application includes a mounting platform 1 and an auxiliary transmission device 2, the mounting platform 1 is placed on the outer periphery of a driven side 101 of a roller 100 to be operated, and an active side 102 of the roller 100 to be operated is connected to a driving transmission device 200; the auxiliary transmission device 2 is arranged on the mounting platform 1, and the auxiliary transmission device 2 is transmission-connected to the driven side 101 of the roller 100 to be operated; the auxiliary transmission device 2 is configured such that when the bearing of the active side 102 of the roller 100 to be operated is replaced, the driving transmission device 200 is closed, and the auxiliary transmission device 2 drives the driven side 101 of the roller 100 to be operated to rotate, so that the roller 100 to be operated rotates.

[0030] Generally, the active side 102 and the driven side 101 of the transition roller of the glass annealing furnace are both provided with bearings, and the driving transmission device 200 is connected to the shaft head of the active side 102 of the transition roller, and the transition roller can be driven to rotate by the driving transmission device 200. The bearings of the active side 102 of the transition roller often need to be replaced. When the bearings of the active side 102 of the transition roller are replaced, the driving transmission device 200 will be closed to stop the drive to the transition roller, and the transition roller will stop rotating. However, in the actual process of replacing the bearings, it was found that when the transition roller stops rotating, it is easy to bend and deform and hit the soft glass ribbon, causing the glass plate to break, affecting production safety.

[0031] In the embodiment of the present application, a mounting platform 1 is placed on the periphery of the driven side 101 of the roller 100 to be operated, that is, the roller whose active side 102 bearing is to be replaced, and an auxiliary transmission device 2 is provided on the mounting platform 1, and the auxiliary transmission device 2 is transmission-connected to the driven side 101 of the roller 100 to be operated. In this way, when the driving transmission device 200 connected to the active side 102 of the roller 100 to be operated stops driving the roller 100 to be operated so that the roller 100 to be operated stops rotating, the auxiliary transmission device 2 can be synchronously started to enable the auxiliary transmission device 2 to transmit the driven side 101 of the roller 100 to be operated, so that the roller 100 to be operated is always in a continuous rotation state, and will not bend and hit the soft glass ribbon due to stopping rotation, causing the risk of glass breakage, thereby effectively avoiding production safety accidents.

[0032] It should be noted that, in the present application, when the driving transmission device 200 connected to the active side 102 of the roller 100 to be operated is closed, in order to keep the roller 100 to be operated rotating continuously, the auxiliary transmission device 2 can be opened synchronously, or the auxiliary transmission device 2 can be opened before the driving transmission device 200 is closed. Of course, since the roller 100 to be operated will still be in a rotating state due to inertia when the driving transmission device 200 is just closed, but the rotation speed continues to decrease, the auxiliary transmission device 2 can be opened after the driving transmission device 200 is closed and before the roller 100 to be operated has not completely stopped rotating. This can prevent the roller 100 to be operated from stopping rotating and prevent the auxiliary transmission device 2 and the driving transmission device 200 from applying inconsistent driving forces to the roller 100 to be operated, resulting in different driving speeds on the active side 102 and the driven side 101 of the roller 100 to be operated, thereby affecting the normal uniform rotation of the roller 100 to be operated.

[0033] It should be noted that, in the embodiment of the present application, shutting down the drive transmission device 200 so that the drive transmission device 200 stops driving the roller 100 to be operated means shutting down the drive transmission device 200 and disconnecting the transmission connection between the drive transmission device 200 and the active side 102 of the roller 100 to be operated.

[0034] In order to safely and smoothly replace the bearing of the active side 102 of the roller 100 to be operated, the speed at which the auxiliary transmission device 2 drives the roller 100 to be operated can be made smaller than the speed at which the driving transmission device 200 drives the roller 100 to be operated, and the roller 100 to be operated needs to be kept rotating at a uniform speed. After the bearing of the active side 102 of the roller 100 to be operated is replaced, the driving transmission device 200 and the shaft head of the active side 102 of the roller 100 to be operated are reconnected, and then the auxiliary transmission device 2 is closed and the transmission connection between the auxiliary transmission device 2 and the driven side 101 of the roller 100 to be operated is disconnected, and the driving transmission device 200 is reopened to drive the roller 100 to be operated to rotate. In this way, during the entire process of replacing the bearing of the active side 102 of the roller 100 to be operated, the roller 100 to be operated will not stop rotating completely, thereby effectively avoiding the bending and deformation of the roller 100 to be operated after stopping, resulting in broken glass plates and affecting production safety.

[0035] In some embodiments, reference Figure 1 The auxiliary transmission device 2 includes an auxiliary driving device 21 and a transmission device 22. The auxiliary driving device 21 is arranged on the mounting platform 1. The transmission device 22 is respectively connected to the auxiliary driving device 21 and the driven side 101 of the roller 100 to be operated; the auxiliary driving device 21 is used to drive the transmission device 200 to rotate to drive the driven side 101 of the roller 100 to be operated to rotate, so that the roller 100 to be operated rotates.

[0036] Specifically, the transmission device 22 is connected to the auxiliary driving device 21 and the driven side 101 of the roller 100 to be operated, so that the driving force generated by the auxiliary driving device 21 will be transmitted to the transmission device 22, and the transmission device 22 will transmit the driving force to the driven side 101 of the roller 100 to be operated, thereby realizing the rotation of the driven side 101 of the roller 100 to be operated, and thus the entire roller 100 to be operated will realize rotation.

[0037] The driving force output by the auxiliary drive device 21 is transmitted to the driven side 101 of the roller 100 to be operated through the transmission device 22, which can reduce the restrictions on the position where the auxiliary drive device 21 can be installed. Moreover, the transmission device 22 can also produce a certain deceleration effect on the rotation speed of the output shaft of the auxiliary drive device 21, so that the driven side 101 of the roller 100 to be operated can rotate slowly and evenly, which is beneficial for the staff to replace the bearing of the active side 102 of the roller 100 to be operated.

[0038] In some embodiments, reference Figure 1 The auxiliary driving device 21 includes a reduction motor, and the transmission device 22 includes a first pulley 221, a second pulley 222 and a V-belt 223 connected between the first pulley 221 and the second pulley 222; the driving shaft of the reduction motor is transmission-connected to the first pulley 221, and the second pulley 222 is transmission-connected to the shaft head of the driven side 101 of the roller 100 to be operated.

[0039] Through the above arrangement, a reduction motor is used to output driving force, and a V-belt pulley structure is utilized to transmit the driving force to the driven side 101 of the roller 100 to be operated. This can make the structure of the auxiliary transmission device 2 simpler, which can not only reduce the manufacturing cost of the device for replacing the roller bearings of the glass annealing furnace, but also make the installation of the device for replacing the roller bearings of the glass annealing furnace simpler and the operation more convenient.

[0040] Specifically, a V-belt pulley structure is used as the transmission device 22, and the distance between the output shaft of the reduction motor and the shaft head of the driven side 101 of the roller 100 to be operated can be adjusted by the length of the V-belt 223. In this way, when the device for replacing the roller bearing of the glass annealing furnace is placed on the outer periphery of the driven side 101 of the roller 100 to be operated, the limitation on the placement position of the mounting platform 1 can be reduced, so that the placement position of the reduction motor will not affect the drive of the driven side 101 of the roller 100 to be operated, and it is more convenient to use.

[0041] In addition, the V-belt pulley structure is a commonly used transmission device 22. When a fault occurs, it is easier for the staff to repair it, or it is easier to replace the V-belt 223 or any one of the first pulley 221 and the second pulley 222, and the replacement cost is lower.

[0042] In some embodiments, the mounting table 1 includes a table top body and a moving mechanism and a lifting mechanism connected to the table top body; the moving mechanism is used to move the table top body to adjust the position of the table top body on the periphery of the driven side 101 of the roller 100 to be operated, and the lifting mechanism is used to lift and lower the table top body to tighten the V-belt 223 to achieve transmission of the driven side 101 of the roller 100 to be operated.

[0043] Through the above arrangement, the auxiliary transmission device 2 is arranged on the table body, and the table body is moved to the periphery of the driven side 101 of the roller 100 to be operated through or moving mechanism, so that the auxiliary transmission device 2 can be connected to the driven side 101 of the roller 100 to be operated. When the driving transmission device 200 connected to the active side 102 of the roller 100 to be operated is closed and disconnected from the active side 102 of the roller 100 to be operated, the driven side 101 of the roller 100 to be operated can be synchronously driven to rotate, so that the roller 100 to be operated can continue to maintain a uniform rotation during the process of replacing the bearing of its active side 102.

[0044] Since the present application adopts a V-belt pulley structure as the transmission device 22, a lifting device is provided to adjust the height of the table body, that is, to adjust the distance between the auxiliary transmission device 2 provided on the table body and the driven side 101 of the roller 100 to be operated, so that the V-belt 223 between the first pulley 221 and the second pulley 222 can be kept tight to ensure effective transmission, thereby better transmitting the driving force output by the driving device to the driven side 101 of the roller 100 to be operated, so that the roller 100 to be operated keeps rotating at a uniform speed.

[0045] Specifically, since the surrounding environment of the driven side 101 of the transition roller is complex, there are many hard pipes and hoses, and there is no reliable installation and fixing surface on the ground, when it is necessary to replace the bearing of the active side 102 of the roller 100 to be operated, the mounting platform 1 can be moved to the driven side 101 of the roller 100 to be operated by a moving device, so that the roller 100 to be operated can always maintain a uniform rotation during the process of replacing the bearing of the active side 102 of the roller 100 to be operated. After the replacement of the bearing of the active side 102 of the roller 100 to be operated is completed, the mounting platform 1 can be moved away again by the moving device. In this way, the device for replacing the roller bearings of the glass annealing furnace does not need to be fixed on the ground, which is more convenient to use. Moreover, when the active side 102 bearings of different rollers need to be replaced, they can be moved to their periphery for auxiliary use, which is more practical.

[0046] In some embodiments, reference Figure 1 and Figure 2The mounting platform 1 is the front fork of the motor forklift. In this way, the auxiliary transmission device 2 is directly mounted on the front fork of the motor forklift, which not only does not require a special mounting platform 1, thus saving costs, but also can better control the position of the auxiliary transmission device 2 relative to the driven side 101 of the roller 100 to be operated, and keep the V-belt 223 in a tensioned state at all times, ensuring effective transmission, and better transmitting the driving force output by the driving device to the driven side 101 of the roller 100 to be operated, so that the roller 100 to be operated can rotate.

[0047] It should be noted that the front fork teeth of the motor forklift serve as a mounting platform 1, which allows the auxiliary transmission device 2 to be located around the driven side 101 of the roller 100 to be operated, and in a suspended state. This can better adapt to the complex environment around the driven side 101 of the transition roller, and will not be affected by the various hard pipes and hoses distributed around the driven side 101 of the transition roller. The environmental installation applicability is improved, and the workload of the staff is further reduced.

[0048] Example, reference Figure 2 There can be multiple transition rollers, and they are arranged in parallel. When it is necessary to replace the bearing of the active side 102 of one of the transition rollers, the motor forklift equipped with the auxiliary transmission device 2 is driven to the vicinity of the driven side 101 of the transition roller, and the auxiliary transmission device 2 is connected to the driven side 101 of the transition roller so as to drive the transition roller to rotate from the driven side 101 of the transition roller. After the bearing of the active side 102 of the transition roller is replaced, the motor forklift can be driven away directly; if the bearing of the active side 102 of another transition roller also needs to be replaced, the motor forklift is directly driven from the driven side 101 of the previous transition roller to the driven side 101 of another transition roller. In this way, the position of the device for replacing the roller bearings of the glass annealing furnace can be changed more quickly and conveniently to meet the bearing replacement needs of the active sides 102 of multiple transition rollers.

[0049] In some embodiments, reference Figure 1 The auxiliary drive device 21 is detachably connected to the mounting platform 1 through the movable fixing clamp 3. In this way, the auxiliary drive device 21 can be quickly installed or removed, making the installation of the auxiliary drive device 21 on the mounting platform 1 simple, fast, time-saving and labor-saving, and having good assembly versatility.

[0050] It should be noted that, when the mounting platform 1 is the front fork of a motorized forklift, the movable fixing clamp 3 can be set on the front fork of the motorized forklift, and then the auxiliary drive device 21 is connected to the movable fixing clamp 3, and then the transmission device 22 is connected between the auxiliary drive device 21 and the driven side 101 of the roller 100 to be operated. In this way, when it is necessary to use a device for replacing roller bearings of a glass annealing furnace, on-site assembly can be performed, which is simple and fast, and saves the cost of specially making a device for replacing roller bearings of a glass annealing furnace.

[0051] Furthermore, the movable fixing clamp 3 is also detachably connected to the front fork teeth of the motor forklift, so that after using the device for replacing the roller bearings of the glass annealing furnace, the motor forklift can be directly driven away, and the auxiliary drive device 21 and the movable fixing clamp 3 can be removed from the front fork teeth of the motor forklift, which will not affect the normal use of the motor forklift and will not occupy the space around the transition roller.

[0052] In some embodiments, the reduction motor is optionally a variable frequency motor, so as to ensure that the transmission speed applied by the auxiliary transmission device 2 to the roller 100 to be operated at the driven side 101 of the roller 100 to be operated is uniform, and is consistent with the main transmission speed applied by the driving transmission device 200 to the roller 100 to be operated at the active side 102 of the roller 100 to be operated.

[0053] In some embodiments, reference Figure 3 The device for replacing roller bearings of a glass annealing furnace further comprises a controller 4, which is electrically connected to the reduction motor and the driving transmission device 200, respectively, and is used to control the start and stop of the driving transmission device 200 and the reduction motor. In this way, the reduction motor can be turned on while the driving transmission device 200 is turned off, so that the transmission force receiving end on the roller 100 to be operated is changed from the active side 102 of the roller 100 to the driven side 101, thereby ensuring that the roller 100 to be operated keeps rotating during the process of replacing the bearing of the active side 102, avoiding the roller 100 to stop rotating and generate bending deformation, resulting in the risk of the soft glass ribbon being broken and the glass plate being broken, thereby reducing the probability of production safety accidents.

[0054] It should be noted that by controlling the start and stop of the drive transmission device 200 and the reduction motor through the controller 4, the automatic start and stop of the drive transmission device 200 and the reduction motor can be achieved. The staff only needs to get close to the driven side 101 of the roller 100 to be operated when assembling and disassembling the connection between the transmission device 22 and the driven side 101 of the roller 100 to be operated. When controlling the start and stop of the reduction motor, there is no need to frequently get close to the driven side 101 of the roller 100 to be operated, which is beneficial to protecting the safety of the staff.

[0055] In some embodiments, the reduction motor is connected to the first pulley 221 through a coupling. This can help the reduction motor and the first pulley 221 to be connected more stably, so that the driving force output by the reduction motor is more stably transmitted to the first pulley 221, thereby improving the transmission effect on the driven side 101 of the roller 100 to be operated, so that the roller 100 to be operated can rotate at a uniform and stable speed.

[0056] In some embodiments, reference Figure 3The coupling is provided with a speed sensor 5, which is electrically connected to the controller 4. The speed sensor 5 can monitor the rotation speed of the first pulley 221 to facilitate adjusting the running speed of the reduction motor, so that the transmission speed provided by the reduction motor for the driven side 101 of the roller 100 to be operated meets the use requirements.

[0057] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
