Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment technology, specifically relating to an electromagnetic stirring roller auxiliary testing device and its testing system. Background Technology

[0002] Electromagnetic stirring rollers play a crucial role in slab continuous casting. Specifically, they drive the molten steel to flow within the slab and between the rollers through transverse electromagnetic thrust, thereby improving the flow state of the molten steel, inhibiting columnar crystal growth, and enhancing the internal quality of the slab. In actual production, to prevent leakage or underperformance of the electromagnetic stirring rollers upon arrival at the site, it is necessary to check the sealing of the finished electromagnetic stirring roller structure and whether its electromagnetic thrust meets expectations.

[0003] like Figure 1 and Figure 2 As shown, the electromagnetic stirring roller is generally mounted on a storage rack via a bearing housing. The storage rack has an A-shaped cross-section, and its structure is consistent with that disclosed in Chinese Invention Patent Application Publication No. CN115401176A. The annular opening of the magnetic shielding device of the electromagnetic stirring roller is opposite to the mounting surface of the bearing housing. When the electromagnetic stirring roller is mounted on the storage rack, the annular opening of the magnetic shielding device generally faces upwards, and its annular structure is consistent with that disclosed in Chinese Invention Patent Application Publication No. CN118253727A. During hoisting, a connecting rod is generally installed on the bearing housing, and the electromagnetic stirring roller is hoisted by connecting the hoisting points on the connecting rod using hoisting tools. When it is necessary to test the electromagnetic strength of a pair of electromagnetic stirring rollers, the pair of electromagnetic stirring rollers need to be placed facing each other so that the annular openings of the magnetic shielding devices of the electromagnetic stirring rollers are opposite each other. In specific operation, the storage rack for the pair of electromagnetic stirring rollers needs to be tilted to one side so that the pair of electromagnetic stirring rollers are placed symmetrically. After dismantling the hoisting tools and connecting rods, the spacing between a pair of electromagnetic stirring rollers was adjusted using a trolley before being moved away. The electromagnetic stirring rollers were then removed from the storage rack, and the magnetic field strength was tested using a testing device. Adjusting the spacing between the pair of electromagnetic stirring rollers in actual operation is quite troublesome, and the mechanical seal inside the bearing housing is easily damaged during the process. Reassembling the electromagnetic stirring rollers back to the storage rack after testing is also cumbersome. Furthermore, it is impossible to simulate the use of electromagnetic stirring rollers on a continuous casting line in a steel plant during production. Therefore, the roller sleeves of the electromagnetic stirring rollers need to be rotated for an extended period with water flowing through them to test the mechanical seal performance and stability of the roller sleeves. Utility Model Content

[0004] In view of the existing technical problems, the present invention aims to provide an auxiliary testing device and system for electromagnetic stirring rollers. This auxiliary testing device for electromagnetic stirring rollers can solve the technical problem of how to conveniently test the magnetic field strength of electromagnetic stirring rollers in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An electromagnetic stirring roller auxiliary testing device is characterized by the following structure: it includes a base, a driving component mounted on the base, and a first component and a second component arranged along the width direction of the base. The first component is fixedly connected to the base. The first component has a first support platform for connecting to a storage rack on the electromagnetic stirring roller. The first support platform is positioned above the base and is rotatable relative to the base. The second component has a second support platform for connecting to the storage rack. The second support platform is positioned above the base and is rotatable relative to the base. The first and second support platforms are arranged parallel to each other. The output end of the driving component is connected to the second component, which is slidably connected to the base. Under the action of the driving component, the second component can move along the width direction of the base, thereby changing the distance between the first and second support platforms.

[0007] In use, the electromagnetic stirring roller auxiliary testing device of this application connects the storage racks on a pair of electromagnetic stirring rollers to a first support platform and a second support platform, respectively. The first and second support platforms are rotated so that the annular openings of the magnetic shielding devices of the pair of electromagnetic stirring rollers face each other. The drive assembly is activated, causing the second assembly to move relative to the first assembly along the width direction of the base, thereby adjusting the distance between the pair of electromagnetic stirring rollers. After adjusting the distance between the pair of electromagnetic stirring rollers to a suitable level, a testing device is placed at the center of the pair of electromagnetic stirring rollers to detect the magnetic field strength between them. This electromagnetic stirring roller auxiliary testing device has a simple and stable overall structure, allowing for flexible adjustment of the position of the electromagnetic stirring rollers, thus facilitating electromagnetic strength testing. This device also maximizes the protection of the mechanical seals of the electromagnetic stirring rollers and enables easy handling and installation, reducing damage caused by installation and testing processes.

One end of the lead screw is rotatably connected to the second connecting seat, and the other end of the lead screw extends outward through the first connecting seat. The lead screw and the first connecting seat are connected by threads. Rotating the outer end of the lead screw causes the second connecting seat to move closer to or further away from the first connecting seat under the action of the lead screw, thereby moving the second assembly along the width direction of the base and adjusting the distance between the first and second assemblies. To facilitate operation of the lead screw, a handle can be provided on the outer end of the lead screw.

[0011] Preferably, the third support platform has rollers at both ends of its bottom, and a guide rail on the base that cooperates with the rollers is provided along the width of the base; a support frame is provided on the guide rail, and the support frame is located on the outside of the second component. The support frame is provided to restrain the second component and prevent it from tipping over during operation.

[0012] Specifically, the first drive mechanism includes a first motor and a first reducer, the output end of the first motor is connected to the input end of the first reducer, and the output end of the first reducer is connected to a first rotating shaft; the second drive mechanism includes a second motor and a second reducer, the output end of the second motor is connected to the input end of the second reducer, and the output end of the second reducer is connected to a second rotating shaft.

[0013] Preferably, the first reducer has two first contact plates, and two first limit switches are provided on the first support portion near the first reducer. Each of the two first limit switches cooperates with one of the two first contact plates, and both first limit switches are electrically connected to the first motor. Similarly, the second reducer has two second contact plates, and two second limit switches are provided on the second support portion near the second reducer. Each of the two second limit switches cooperates with one of the two second contact plates, and both second limit switches are electrically connected to the second motor. By using the contact plates and limit switches, the rotation angles of the first and second shafts are controlled. When a limit switch rotates to contact a contact plate, the corresponding motor stops operating.

[0014] Preferably, both the first and second support platforms are provided with slidingly connected snap-fit ​​portions, the outer ends of which are used for detachable and fixed connection with the storage rack. By providing slidingly connected snap-fit ​​portions, the connection positions of the first and second support platforms with the storage rack can be adjusted as needed, improving the convenience of installation and connection.

[0015] Preferably, both the first support platform and the second support platform are formed by connecting two parallel channel steel sections, with a gap between the two channel steel sections, and both channel steel sections are arranged along the length of the base. The locking part includes a first connecting block, a first locking block, and a limiting block disposed between the first connecting block and the first locking block. The two sides of the limiting block are respectively connected to the first connecting block and the first locking block. The first locking block is used to lock with the storage rack. The first connecting block is provided with two second locking blocks, both of which are disposed between the first connecting block and the limiting block, and there is a gap between the second locking blocks and the limiting block.

[0016] Based on the same inventive concept, this application also provides an electromagnetic stirring roller testing system, including the electromagnetic stirring roller auxiliary testing device as described above, a pair of electromagnetic stirring rollers, and a roller sleeve rotating device. The roller sleeve rotating device includes a third motor, a speed distribution box, two parallel third rotating shafts, multiple bearing seats, and a belt.

The third rotating shafts are arranged along the length direction of the base, and the two third rotating shafts are rotatably connected to the bearing seats respectively. The output end of the third motor is connected to the speed distribution box, which has two output ends, and the two output ends are respectively connected to the third rotating shafts.

[0017] When simulating operation on a continuous casting line, the storage racks on a pair of electromagnetic stirring rollers are connected to the first and second support platforms, respectively. The first and second support platforms are rotated so that the pair of electromagnetic stirring rollers are positioned opposite two third rotating shafts. The surfaces of the third rotating shafts are designed to have high friction. Belts are fitted onto the roller sleeves of the third rotating shafts and electromagnetic stirring rollers. The roller sleeve rotation device is moved, and the drive assembly is activated, ensuring that the belts on both third rotating shafts are taut. The third motor is started, causing the two third rotating shafts to rotate, which in turn drives the roller sleeves of the electromagnetic stirring rollers on both sides to rotate via the belts. This simulates the operation of the electromagnetic stirring rollers on a continuous casting line, allowing for the testing of the mechanical sealing performance and stability of the roller sleeves. When a magnetic field strength test is required, the roller sleeve rotation device is moved out of the base, the position of the pair of electromagnetic stirring rollers is adjusted as needed, and the magnetic field strength testing device is placed at the center of the pair of electromagnetic stirring rollers to measure the magnetic field strength between them.

The base 1 has guide rails 7 that cooperate with the rollers 307, and these guide rails 7 are arranged along the width direction of the base 1. A support frame 8 is provided on the guide rail 7, and this support frame 8 is located on the outside of the second component 3. Figure 6 As shown, the drive assembly 4 includes a lead screw 401, a first connecting seat 402, and a second connecting seat 403.

One end of the lead screw 401 is rotatably connected to the second connecting seat 403, and the other end of the lead screw 401 extends outward through the first connecting seat 402. The lead screw 401 and the first connecting seat 402 are connected by threads. A handle is provided on the outer end of the lead screw 401, and the handle is rotatably connected to the lead screw 401. Figure 7 As shown, both the top of the first support base 204 and the second support base 304 are equipped with bearings. The first support base 204 is rotatably connected to the first rotating shaft 203 via bearings, and the second support base 304 is rotatably connected to the second rotating shaft 303 via bearings. Figure 3 As shown, both the first support platform 201 and the second support platform 301 are provided with slidingly connected snap-fit ​​parts 13, the outer end of which is used for detachable and fixed connection with the storage rack 6. Figure 4 and Figure 5 As shown, both the first support platform 201 and the second support platform 301 are connected by two parallel channel steel sections 14, with a gap between them. Both channel steel sections 14 are arranged along the length of the base 1. The channel steel sections 14 are over 3m long, thus accommodating most electromagnetic stirring rollers 5 currently on the market. Figure 9As shown, the latching part 13 includes a first connecting block 1301, a first latching block 1302, and a limiting block 1303 disposed between the first connecting block 1301 and the first latching block 1302.

The distance between the first component 2 and the second component 3 should take into account the maximum height from the contact surface of the storage rack 6 and the snap-fit ​​part 13 to the roller surface of the electromagnetic stirring roller 5, and the center distance from the contact surface of the snap-fit ​​part 13 and the storage rack 6 to the first rotating shaft 203 or the second rotating shaft 303. For example, if the height of the contact surface of the storage rack 6 from the mounting surface of the electromagnetic stirring roller 5 is 400mm, the farthest distance from the bottom surface of the bearing seat of the electromagnetic stirring roller 5 to the roller surface is 300mm, and the center distance from the contact surface of the snap-fit ​​part 13 and the storage rack 6 to the first rotating shaft 203 is 200mm, then the minimum distance between the first rotating shaft 203 of the first component 2 and the second rotating shaft 303 of the second component 3 should be slightly greater than (400+300+200)*2=1800mm. The maximum distance can be increased according to the maximum thickness of the slab in the market and leave a margin.

[0043] like Figure 11 As shown, this embodiment also provides an electromagnetic stirring roller testing system including the electromagnetic stirring roller auxiliary testing device described above, a pair of electromagnetic stirring rollers 5, and a roller sleeve rotating device 15. The roller sleeve rotating device 15 includes a third motor 1501, a speed distribution box 1502, two parallel third rotating shafts 1503, three bearing seats 1504, and a belt 1505. The belt 1505 is used to fit over the roller sleeves of the third rotating shafts 1503 and the electromagnetic stirring rollers 5. The third rotating shafts 1503 are arranged along the length of the base 1, and the two third rotating shafts 1503 are rotatably connected to the bearing seats 1504 respectively. The output end of the third motor 1501 is connected to the speed distribution box 1502, which has two output ends, each connected to one of the third rotating shafts 1503. Figure 12 As shown, the electromagnetic stirring roller 5 is positioned on top of the storage rack 6. Figure 13 As shown, by moving the latching part 13, the first latching block 1302 of the latching part 13 is latched with the middle part of the storage rack 6, thereby fixing the electromagnetic stirring roller 5 on the storage rack 6 onto the first support platform 201 and the second support platform 301.

[0044] When testing the electromagnetic strength of the electromagnetic stirring rollers, the first motor 202-1 and the second motor 302-1 are started, so that the first locking block 1302 on the locking part 13 faces upward. The storage rack 6 on the pair of electromagnetic stirring rollers 5 is locked with the locking part 13 on the first support platform 201 and the second support platform 301, respectively. At this time, the annular opening of the magnetic shielding device of the electromagnetic stirring roller 5 is set upward. The first motor 202-1 and the second motor 302-1 are started, so that the first support platform 201 and the second support platform 301 are rotated 90° respectively, so that the annular opening of the magnetic shielding device of the pair of electromagnetic stirring rollers 5 is set opposite to each other. The lead screw 401 on the drive assembly 4 is rotated, so that the second support platform 301 moves relative to the first support platform 201 along the width direction of the base 1, thereby adjusting the distance between the pair of electromagnetic stirring rollers 5. After adjusting the distance between the pair of electromagnetic stirring rollers 5 to a suitable distance, a testing device is placed at the center of the pair of electromagnetic stirring rollers 5 to detect the magnetic field strength between the electromagnetic stirring rollers 5. The testing device is an existing product. When simulating the use on a continuous casting line, the test device is moved out of base 1, and the roller sleeve rotating device 15 is placed on base 1, with the third rotating shaft 1503 parallel to the electromagnetic stirring rollers 5. A belt 1505 is fitted onto the roller sleeves of the third rotating shaft 1503 and the pair of electromagnetic stirring rollers 5. The positions of the roller sleeve rotating device 15 and the second component 3 are adjusted so that the belt 1505 is taut. Water is introduced into the pair of electromagnetic stirring rollers 5, and the third motor 1501 is started, causing the third rotating shaft 1503 to rotate and, through the belt 1505, to drive the roller sleeves of the electromagnetic stirring rollers 5 to rotate, thereby simulating the use of the electromagnetic stirring rollers 5 on a continuous casting line to test the mechanical sealing performance and stability of the roller sleeves. After the test is completed, start the first motor 202-1 and the second motor 302-1 to rotate the first support platform 201 and the second support platform 301 by 90°. At this time, the ring openings of the magnetic shielding devices of the pair of electromagnetic stirring rollers 5 are facing upwards. Remove the storage racks 6 of the pair of electromagnetic stirring rollers 5 from the first support platform 201 and the second support platform 301 respectively.

[0045] Example 2

[0046] like Figure 14As shown, the structure of the electromagnetic stirring roller auxiliary testing device in this embodiment is the same as that in Embodiment 1, except that the first reducer 202-2 is provided with two first contact plates 9, and the first support part 205 near the first reducer 202-2 is provided with two first limit switches 10. The two first limit switches 10 cooperate with the two first contact plates 9 respectively, and both first limit switches 10 are electrically connected to the first motor 202-1. The two first contact plates 9 are spaced apart along the height direction of the first reducer 202-2, and the included angle between the two first limit switches 10 is 90 degrees. The second reducer 302-2 is provided with two second contact plates 11, and the second support part 305 near the second reducer 302-2 is provided with two second limit switches 12. The two second limit switches 12 cooperate with the two second contact plates 11 respectively, and both second limit switches 12 are electrically connected to the second motor 302-1. Two second contact plates 11 are spaced apart along the height direction of the second reducer 302-2, and the included angle between the two second limit switches 12 is 90 degrees. By setting the first limit switch 10 and the second limit switch 12, the rotation angle of the first rotating shaft 203 and the second rotating shaft 303 can be precisely controlled. When it is necessary to test the electromagnetic stirring roller, it is only necessary to start the first motor 202-1 and the second motor 302-1. When the first rotating shaft 203 and the second rotating shaft 303 rotate 90° respectively, the first limit switch 10 abuts against the first contact plate 9, and the first motor 202-1 stops working. The second limit switch 12 abuts against the second contact plate 11, and the second motor 302-1 stops working, thereby allowing precise control of the rotation angle of the first rotating shaft 203 and the second rotating shaft 303.
