Technical Field
[0001] This utility model relates to the field of bearing housing assembly technology, and in particular to an assembly structure for a rolling mill roll and a bearing housing. Background Technology
[0002] The assembly structure of the rolls and bearing housings is a core component of the rolling mill, directly affecting rolling accuracy, equipment lifespan, and operational stability. Furthermore, during installation, the rolls and bearing housings must be precisely aligned with the center axis; this is a crucial requirement for ensuring normal mill operation, extending equipment lifespan, and guaranteeing rolling quality.
[0003] If the centerline of the roll is not aligned with the centerline of the bearing housing during installation, the bearing will be subjected to additional radial or axial forces, leading to localized overload. This will also induce system resonance, causing increased mill vibration and accelerating bearing raceway spalling.
[0004] However, in the existing technology, there are various ways to align the centerline of the roll with the centerline of the mounting hole of the bearing housing, such as mechanical alignment and hydraulic alignment. However, the above calibration methods all require the staff to use additional components to check the alignment, which makes the alignment process of the roll installation more complicated. In addition, when the roll slips during operation, the existing technology cannot detect it in time, resulting in severe wear of the roll.
[0005] Therefore, it is necessary to solve the above problems by means of an assembly structure for the roll and bearing housing. Utility Model Content
[0006] The purpose of this invention is to provide an assembly structure for a rolling mill roll and a bearing housing, so as to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an assembly structure for a roll and a bearing housing, comprising a bearing housing body and a roll body, wherein the bearing housing body is provided with a mounting hole, a detection component is provided along the edge of the mounting hole, a translation component is provided at the bottom of the bearing housing body, a lifting electric cylinder is provided at the bottom of the translation component, and a blind hole is provided along the circumferential edge of the mounting hole on the bearing housing body, wherein the detection component is disposed in the blind hole; It also includes a remote control center, which is connected to the detection component, the translation component and the lifting electric cylinder via electrical signals.
[0008] Preferably, the detection assembly includes a movable upright plate and a pressure sensor disposed at the inner end of the blind hole. A translation column is disposed on the side of the movable upright plate near the pressure sensor, and a buffer spring is disposed on the end of the translation column away from the movable upright plate.
[0009] Preferably, a fixed protruding ring is provided inside the blind hole, and the end of the buffer spring away from the translation column is fixedly mounted on the fixed protruding ring, and the contact end of the pressure sensor passes through the fixed protruding ring.
[0010] Preferably, the translation assembly includes a translation electric cylinder, the output end of which is fixedly connected to a push plate, and a translation horizontal plate is fixedly installed on the top of the push plate. The bearing housing body is installed on the translation horizontal plate by a fixed mounting buckle.
[0011] Preferably, the translation component further includes a support box, which is fixedly installed at the output end of the lifting electric cylinder, and the translation electric cylinder is fixedly installed inside the support box; The support box has a through hole on its top surface, the sliding plate is slidably disposed on the top surface of the support box, and the top of the push plate passes through the through hole and is connected to the sliding plate.
[0012] Preferably, a movable chassis assembly is provided at the bottom of the lifting electric cylinder, the roller body is placed on the support frame, a track is provided on the bottom of the support frame near the lifting electric cylinder, the movable chassis assembly is placed on the track and moves back and forth along the track.
[0013] Preferably, the mobile chassis assembly includes a travel motor, travel wheels, and a support chassis. The travel motor and travel wheels are mounted on the bottom surface of the support chassis. The travel wheels are mounted on the end of the output shaft of the travel motor. The remote control center is connected to the travel motor via an electrical signal.
[0014] The technical effects and advantages of this utility model are as follows: 1. In this utility model, a detection component is set up to detect whether the central axis of the roll body is aligned with the central axis of the mounting hole of the bearing housing body during the installation process. The detection result data is transmitted to the remote control center. After receiving the data, the remote control center determines the direction of the offset and adjusts the position of the bearing housing body by controlling the translation component and the lifting electric cylinder to align the mounting hole with the roll body. The alignment method is simple and quick, without the need for additional components. In addition, during the rotation of the roll body after it is installed in the mounting hole, the detection component can determine whether the roll body is slipping and promptly feeds back to the remote control center. The remote control center alarms to prompt the staff to stop the machine for inspection, avoiding the failure to quickly and promptly detect slippage, which could lead to severe wear of the roll.
[0015] 2. In this utility model, by setting pressure sensors, moving vertical plates, and translation columns, the offset of the mounting hole relative to the roll body is detected during the installation process of the roll body. The pressure sensors that are under pressure transmit pressure signals to the remote control center through electrical signals. After receiving the data, the remote control center determines the relative offset direction of the current mounting hole, thereby controlling the translation components and lifting electric cylinder to adjust the position of the bearing box body, so that the roll body and the mounting hole can be quickly aligned without the aid of external components.
[0016] 3. In this utility model, by setting a pressure sensor, a movable vertical plate and a translation column, whether the pressure signal of the pressure sensor disappears during the operation of the roll body can be used as a signal for whether the roll body has detached. This allows the remote control center to quickly and timely determine the slippage situation and notify the staff to check, thus avoiding the occurrence of severe wear of the roll body.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0020] To address the problems in the existing technology where the alignment of the roll's central axis with the bearing housing's mounting hole 2 requires additional components for inspection and alignment, making the roll installation process cumbersome and the inability of the existing structure to detect slippage during roll operation in a timely manner, leading to severe roll wear, the following embodiments are proposed.
[0021] This utility model provides, for example Figures 1 to 6 The assembly structure of a roll and bearing housing shown includes a bearing housing body 1 and a roll body 5. The bearing housing body 1 is provided with a mounting hole 2, and a detection component 3 is provided along the edge of the mounting hole 2. A translation component 4 is provided at the bottom of the bearing housing body 1, and a lifting electric cylinder 6 is provided at the bottom of the translation component 4. A blind hole is provided on the bearing housing body 1 along the circumferential edge of the mounting hole 2, and the detection component 3 is disposed in the blind hole. The assembly structure also includes a remote control center, which is connected to the detection component 3, the translation component 4 and the lifting electric cylinder 6 via electrical signals.
[0022] The bottom of the lifting electric cylinder 6 is provided with a movable chassis assembly 7, the roller body 5 is placed on the support frame 9, and the bottom of the support frame 9 is provided with a track 8 on the side near the lifting electric cylinder 6. The movable chassis assembly 7 is placed on the track 8 and moves back and forth along the track 8.
[0023] During installation, the staff uses a remote control center to control the mobile chassis assembly 7 to move the bearing housing body 1 along the track 8 closer to the end of the roll body 5 until the end face of the roll body 5 touches the detection assembly 3, at which point the movement of the mobile chassis assembly 7 stops.
[0024] By setting up detection component 3, the alignment of the central axis of the roll body 5 with the central axis of the mounting hole 2 of the bearing housing body 1 during the installation process is detected, and the detection result data is transmitted to the remote control center. After receiving the data, the remote control center determines the direction of the offset and adjusts the position of the bearing housing body 1 by controlling the translation component 4 and the lifting electric cylinder 6 to align the mounting hole 2 with the roll body 5. The alignment method is simple and quick, without the need for additional components. In addition, during the rotation of the roll body 5 after it is installed in the mounting hole 2, the detection component 3 can determine whether the roll body 5 is slipping, and promptly feeds back to the remote control center. The remote control center will then issue an alarm to prompt the staff to stop the machine for inspection, thus avoiding the failure to quickly and promptly detect slippage, which could lead to severe wear of the roll.
[0025] like Figure 3 As shown, the detection component 3 includes a movable upright plate 301 and a pressure sensor 304 disposed at the inner end of the blind hole. A translation column 302 is disposed on the side of the movable upright plate 301 near the pressure sensor 304. A buffer spring 303 is disposed at the end of the translation column 302 away from the movable upright plate 301. When the movable upright plate 301 is pressed, the pressure sensor 304 is subjected to pressure, the buffer spring 303 is compressed and generates a corresponding elastic force. When the movable upright plate 301 is not pressed, the elastic force of the buffer spring 303 will drive the translation column 302 to reset. When the translation column 302 moves away from the pressure sensor 304 and moves towards the outside of the blind hole, the pressure on the pressure sensor 304 disappears. A fixed protrusion ring is disposed inside the blind hole. The end of the buffer spring 303 away from the translation column 302 is fixedly disposed on the fixed protrusion ring. The contact end of the pressure sensor 304 passes through the fixed protrusion ring.
[0026] In use, the end face of the roll body 5 abuts against the movable vertical plate 301, causing the movable vertical plate 301 to move into the blind hole, thereby driving the translation column 302 to move. The end of the translation column 302 abuts against the contact end of the pressure sensor 304, causing part of the pressure sensor 304 to be under pressure and send a signal to the remote control center. The remote control center receives the signal and stops the movement of the movable chassis assembly 7.
[0027] Simultaneously, the remote control center, based on the position of the pressure sensor 304 that emitted the signal, confirms the offset direction of the mounting hole 2 relative to the roll body 5, thereby determining the direction in which the bearing housing body 1 needs to move. (Reference) Figure 2When the pressure sensors 304 located at the left and lower positions emit signals, it indicates that the current position of the mounting hole 2 is too far to the upper right and needs to be moved to the lower left. Therefore, the remote control center controls the output end of the lifting electric cylinder 6 to retract, causing the bearing housing body 1 to move downward. At the same time, the control center controls the output end of the translation component 4 to move the bearing housing body 1 to the left. This continues until all pressure sensors 304 emit no pressure signals, indicating that the central axis of the current mounting hole 2 is aligned with the central axis of the roll body 5. At this point, the remote control center resumes the movement of the moving chassis assembly 7 until the roll body 5 is installed in place, and then stops the movement of the moving chassis assembly 7.
[0028] refer to Figures 5-6 When the roll body 5 is installed in place, the end face of its outer diameter will abut against the moving vertical plate 301, so that all the pressure sensors 304 are subjected to pressure and send a signal to the remote control center. The remote control center receives the signal, determines that the roll body 5 has been installed in place, and stops the moving chassis assembly 7 from moving further.
[0029] When the roll body 5 is rotating, the pressure signal from the pressure sensor 304 disappears, indicating that the roll body 5 has slipped. This causes the moving vertical plate 301 to move outward from the blind hole, and the end of the translation column 302 to leave the contact end of the pressure sensor 304, thus causing the pressure signal to disappear. At this time, the remote control center issues an alarm to remind the staff that the roll body 5 has slipped and that the machine should be stopped for inspection.
[0030] By setting up a pressure sensor 304, a movable vertical plate 301, and a translation column 302, the offset of the mounting hole 2 relative to the roll body 5 is detected during the installation process. The pressure sensor 304, which is partially under pressure, transmits the pressure signal to the remote control center through an electrical signal. After receiving the data, the remote control center determines the current relative offset direction of the mounting hole 2, and then controls the translation component 4 and the lifting electric cylinder 6 to make adjustments, so that the roll body 5 and the mounting hole 2 can be quickly aligned without the aid of external components.
[0031] By setting up a pressure sensor 304, a movable vertical plate 301, and a translation column 302, the disappearance of the pressure signal of the pressure sensor 304 during the operation of the roll body 5 can be used as a signal to indicate whether the roll body 5 has detached. This allows the remote control center to quickly and timely determine the slippage situation and notify the staff to conduct an inspection, thus preventing the roll body 5 from experiencing severe wear.
[0032] like Figure 4As shown, the translation assembly 4 includes a translation electric cylinder 403, a push plate 402 is fixedly connected to the output end of the translation electric cylinder 403, a translation horizontal plate 404 is fixedly installed on the top of the push plate 402, and the bearing housing body 1 is installed on the translation horizontal plate 404 by a fixed mounting buckle 405; the translation assembly 4 also includes a support box 401, the support box 401 is fixedly installed on the output end of the lifting electric cylinder 6, and the translation electric cylinder 403 is fixedly installed inside the support box 401; a through hole is opened on the top surface of the support box 401, the translation horizontal plate 404 is slidably disposed on the top surface of the support box 401, and the top of the push plate 402 passes through the through hole and is connected to the translation horizontal plate 404.
[0033] When in use, if the bearing housing body 1 needs to be moved left or right, the remote control center controls the output end of the translation electric cylinder 403 to extend or retract, thereby driving the translation horizontal plate 404 to move left or right through the push plate 402, and the translation horizontal plate 404 drives the bearing housing body 1 to move left or right for adjustment.
[0034] like Figure 2 As shown, the mobile chassis assembly 7 includes a travel motor 701, a travel wheel 702, and a support chassis 703. The travel motor 701 and the travel wheel 702 are mounted on the bottom surface of the support chassis 703. The travel wheel 702 is mounted on the end of the output shaft of the travel motor 701. The remote control center is connected to the travel motor 701 via an electrical signal. The travel wheel 702 has a groove along its circumference, which fits into the track 8, thereby enabling the travel wheel 702 to roll along the track 8.
[0035] In use, the remote control center controls the start and stop of the travel motor 701 to drive the travel wheel 702 to move and stop along the track 8, thereby driving the bearing housing body 1 closer to the roll body 5 until the installation is completed.
[0036] The working principle of this utility model is as follows: First, the bearing housing is moved to the detection position. The operator controls the traveling motor 701 to drive the traveling wheel 702 to move along the track 8 towards the roll body 5 through the remote control center. This causes the bearing housing body 1 to move closer to the roll body 5 until the end face of the roll body 5 abuts against the moving upright plate 301, causing the moving upright plate 301 to move into the blind hole. This causes the translation column 302 to move. The end of the translation column 302 abuts against the contact end of the pressure sensor 304, causing part of the pressure sensor 304 to be under pressure and send a signal to the remote control center, indicating that the bearing housing body 1 has moved to the detection position. The remote control center receives the signal and stops the operation of the traveling motor 701.
[0037] Secondly, the relative offset direction is detected and alignment is adjusted. Based on the position of the pressure sensor 304 that sends the signal, the remote control center confirms the offset direction of the mounting hole 2 relative to the roll body 5, thereby determining the direction in which the bearing housing body 1 needs to move. For example: (Refer to...) Figure 2 When the pressure sensors 304 located at the left and lower positions emit signals, it indicates that the current position of the mounting hole 2 is too far to the upper right and needs to be moved to the lower left. Therefore, the remote control center controls the output end of the lifting electric cylinder 6 to retract, causing the bearing housing body 1 to move downward. At the same time, it controls the output end of the translation component 4 to move the bearing housing body 1 to the left. This continues until all pressure sensors 304 emit no pressure signals, indicating that the central axis of the current mounting hole 2 is aligned with the central axis of the roll body 5. At this point, the remote control center resumes the operation of the moving travel motor 701.
[0038] Then, the roll body 5 is installed and put into operation. When all the pressure sensors 304 are under pressure, they send a signal to the remote control center. The remote control center receives the signal and determines that the roll body 5 is now installed. The outer diameter end face of the roll body 5 will abut against the moving vertical plate 301, so that all the pressure sensors 304 are under pressure. At this time, the operation of the travel motor 701 is stopped and the roll body 5 is started to run.
[0039] Finally, when the roll body 5 is rotating, the pressure signal from the pressure sensor 304 disappears, indicating that the roll body 5 has slipped. This causes the moving vertical plate 301 to move outward from the blind hole, and the end of the translation column 302 to leave the contact end of the pressure sensor 304, thus causing the pressure signal to disappear. At this time, the remote control center issues an alarm to remind the staff that the roll body 5 has slipped and that the machine should be stopped for inspection.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
