Abstract
Description
Technical Field
[0001] This utility model relates to the field of polishing machine technology, and in particular to a device for handling accidents during the replacement of polishing machine rolls. Background Art
[0002] The surface quality of strip steel after passing through the finishing mill is particularly important. Once it is determined that the quality defects on the strip steel surface are caused by roll defects, the rolls must be replaced promptly. The original design of the finishing mill rolling line equipment did not have mechanical limit positions. If the rolling line equipment exceeds the limits during operation, roll replacement will fail. To ensure that the rolling line equipment does not exceed the limits during roll replacement, an electrical program is used to protect the rolling line equipment from exceeding the limits. However, the electrical program can occasionally malfunction, causing the rolling line equipment to run beyond the limits due to poor limit protection, resulting in contact with the gate. In the event of such an accident, the rolling line equipment must be manually moved back below the programmed limit protection and the transmission must be restarted. However, without a dedicated handling device, this process will prolong the repair and maintenance time, increase the workload, and hinder the unit's rapid resumption of production. Utility Model Content
[0003] The purpose of this utility model is to provide a device for handling accidents involving the replacement of rolls in a finishing mill, so as to solve the problems existing in the prior art. It has a simple structure, is easy to use, and effectively shortens the accident handling time and reduces the workload of emergency repair and maintenance.
[0004] To achieve the above objectives, this utility model provides the following solution:
[0005] This utility model provides a rolling mill roll replacement accident handling device, including: a locking part and a handle part. The locking part is used to lock and connect with the transition shaft used for assembling the reducer and the motor. The handle part is used to drive the locking part to rotate so that the locking part drives the transition shaft to rotate, thereby driving the reducer to run the rolling line device to escape the accident state.
[0006] Preferably, the latching part includes a limiting plate and a latching plate. The top of the latching plate is fixedly connected to the handle part. The latching plate is fixedly connected to the limiting plate. The latching plate and the limiting plate are used to extend into the shaft hole of the transition shaft. The latching plate is used to contact one side of the connecting key in the shaft hole of the transition shaft. The limiting plate is used to abut against the inner wall of the shaft hole of the transition shaft so that when the handle part drives the latching part to rotate, the latching plate can press against the connecting key in the shaft hole of the transition shaft and drive the transition shaft to rotate.
[0007] Preferably, it further includes an extension plate, which is integrally connected to the top of the limiting plate, and the top of the extension plate is used to fix it to the handle portion. The diameter of the extension plate is larger than the diameter of the transition shaft hole.
[0008] Preferably, the handle is an operating lever, and the top of the snap-fit plate is fixedly connected to the middle of the operating lever.
[0009] Preferably, the snap-fit plate is vertically fixed to the middle of the limiting plate.
[0010] Preferably, the snap-fit plate is vertically fixed to the middle of the extension plate.
[0011] Preferably, the length of the operating lever is two meters.
[0012] The present invention achieves the following technical advantages over the prior art:
[0013] This invention provides a device for handling roll replacement accidents in a finishing mill. When the finishing mill rolling line exceeds its protection limit, the drive motor is first removed, and the locking part is engaged in the shaft hole of the transition shaft used for assembling the reducer and motor. After confirming that the locking part is in place, the handle is manually rotated along the downward direction of the rolling line. In this way, the over-limit rolling line is brought back below the program limit, thus avoiding the inability to perform subsequent operations due to the rolling line exceeding the limit and restoring the rolling line to its normal operating range.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] The purpose of this utility model is to provide a device for handling accidents involving the replacement of rolls in a finishing mill, so as to solve the problems existing in the prior art. It has a simple structure, is easy to use, and effectively shortens the accident handling time and reduces the workload of emergency repair and maintenance.
[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0022] This utility model provides a device 100 for handling accidents involving the replacement of rolls in a finishing mill, such as... Figures 1-3 As shown, the device includes a locking part and a handle part. The locking part is used to engage with the transition shaft 5 used for assembling the reducer 8 and the motor. The handle part is used to rotate the locking part so that it drives the transition shaft 5 to rotate, thereby driving the reducer 8 and bringing the rolling line device out of the accident state. When the rolling line device exceeds the protection limit, the drive motor is first removed, and the locking part is engaged in the shaft hole 6 of the transition shaft 5 used for assembling the reducer 8 and the motor. After confirming that the locking part is in place, the handle part is manually rotated along the downward direction of the rolling line device. In this way, the over-limit rolling line device is brought back below the program limit, thus avoiding the inability to perform subsequent operations due to the rolling line device exceeding the limit and restoring the rolling line device to its normal operating range.
[0023] In a preferred embodiment, the latching part includes a limiting plate 2 and a latching plate 1. The top of the latching plate 1 is fixedly connected to the handle part. The latching plate 1 and the limiting plate 2 are fixedly connected. The latching plate 1 and the limiting plate 2 are used to extend into the shaft hole 6 of the transition shaft 5. The latching plate 1 is used to contact one side of the connecting key 7 in the shaft hole 6 of the transition shaft 5. The limiting plate 2 is used to abut against the inner wall of the shaft hole 6 of the transition shaft 5 so that when the handle part drives the latching part to rotate, the latching plate 1 can press against the connecting key 7 in the shaft hole 6 of the transition shaft 5 and drive the transition shaft to rotate. The setting of the extension plate 3 increases the connection area with the handle part and improves the stability of the connection. At the same time, its diameter is larger than the diameter of the shaft hole 6 of the transition shaft 5, which can play a limiting role and prevent the latching part from extending too far into the shaft hole 6 of the transition shaft 5, thus ensuring the safety of the device.
[0024] In a preferred embodiment, the roller replacement accident handling device 100 for the finishing mill also includes an extension plate 3, which is integrally connected to the top of the limiting plate 2. The top of the extension plate 3 is used to fix the handle. The diameter of the extension plate 3 is larger than the diameter of the shaft hole 6 of the transition shaft 5. The handle is designed as an operating rod 4, which is convenient for the operator to hold and operate. The fixed connection between the snap plate and the middle of the operating rod 4 makes the operation more stable and facilitates the application of force to drive the snap plate to rotate.
[0025] In a preferred embodiment, the handle is an operating lever 4, and the top of the snap-fit plate is fixedly connected to the middle of the operating lever 4. The snap-fit plate 1 is vertically fixedly connected to the middle of the limiting plate 2, which enables the snap-fit plate 1 to better contact and abut against the connecting key 7 in the shaft hole 6 of the transition shaft 5 during rotation, thereby improving transmission efficiency and stability.
[0026] In a preferred embodiment, the snap-fit plate 1 is vertically fixedly connected to the middle of the limiting plate 2.
[0027] In a preferred embodiment, the snap-fit plate 1 is vertically fixed to the middle of the extension plate 3. This vertical fixed connection between the snap-fit plate 1 and the extension plate 3 also helps to improve the overall structural stability of the device, ensuring that the various components can work together during operation and effectively handle accidents.
[0028] In a preferred embodiment, the length of the operating lever 4 is two meters. The design of the operating lever 4 with a length of two meters can provide the operator with a suitable operating distance during operation, which is convenient for applying force, ensures the safety of the operator, and also adapts to the needs of different operating scenarios.
[0029] The following is the usage process of the finishing mill roll replacement accident handling device 100 provided by the present invention:
[0030] I. Preparation Stage
[0031] When an accident occurs during the roll change process of the finishing mill, causing the rolling line to operate out of the accident state, this treatment device is prepared to be used.
[0032] II. Inspection and Installation Phase
[0033] Check the condition of transition shaft 5 to ensure it is in an operable state.
[0034] The limiting plate 2 and the locking plate 1 of the locking part are inserted into the shaft hole 6 of the transition shaft 5, so that the locking plate 1 contacts one side of the connecting key 7 in the shaft hole 6 of the transition shaft 5, and the limiting plate 2 abuts against the inner wall of the shaft hole 6 of the transition shaft 5.
[0035] Securely connect the outer plate 3 to the handle (operating lever 4) to ensure a firm connection.
[0036] The top of the snap-fit plate is fixedly connected to the middle of the operating lever 4.
[0037] III. Operational Phase
[0038] The operator holds the operating lever 4 and rotates the locking part by moving the handle.
[0039] During rotation, the snap-fit plate 1 presses against the connecting key 7 inside the shaft hole 6 of the transition shaft 5, causing the transition shaft 5 to rotate.
[0040] The rotation of the transition shaft 5 drives the reducer 8, enabling the rolling line unit to operate out of the accident state.
[0041] IV. Completion Phase
[0042] Once it is confirmed that the rolling line equipment is out of the accident state, operation should be stopped.
[0043] If further operations are required, adjustments and processing can be made according to the actual situation.
[0044] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
