[0001] The invention relates to the technical field of dynamic balance detection of a cone box of a finishing mill, and in particular to a cone box fault diagnosis device and method based on vibration testing. Background Art

[0002] The finishing mill is used in high-speed wire workshops and generally consists of four rolling mills, all of which are cantilever roller ring type stands, arranged alternately horizontally and vertically. Vertical loopers are installed between the stands to achieve tension-free rolling.

[0003] The finishing mill is arranged behind the middle roller table or hot coil box of the roughing mill. Its equipment includes the front roller table of the crop flying shear, the side guide plate of the crop flying shear, the speed measuring device of the crop flying shear, the edge heater, the crop flying shear and the crop collecting device, the finishing mill descaling box, the front vertical roller mill of the finishing mill, the finishing mill, the looper device, the inlet and outlet guide plates of the finishing mill, the dust removal device of the finishing mill, the roller changing device of the finishing mill, etc.

[0004] The finishing mill is a finished product rolling mill and the core part of hot rolled strip production. The quality level of rolled products mainly depends on the technical equipment level and control level of the finishing mill group.

[0005] The cone box of the finishing mill is a gear box, which is used to transmit the power of the motor to the processing position. The cone box of the finishing mill provides power to the finishing mill through the cooperation of the gear set. When installing the gears and shaft structure inside the cone box of the finishing mill, dynamic balancing tests need to be performed to ensure the smooth operation of the gears.

[0006] At present, various types of cone box faults are classified and described based on the harmonic method. For example, the vibration spectrum characteristics of the cone box when there is a bearing outer ring fault in the cone box; the harmonic characteristics in the cone box vibration spectrum diagram when faults such as gear wear, tooth breaking, and shaft cracks occur. When performing dynamic balancing detection on the gears and shaft structures inside the cone box of the finishing mill, the shaft structure is placed on a roller bracket, and then the shaft structure is driven to rotate on the roller bracket by a belt, and the vibration sensor is used to detect the amount of shaft runout, thereby testing whether the gear shaft is balanced.

[0007] The patent with publication number CN118500627A discloses a finishing mill cone box installation dynamic balance test device and auxiliary positioning tooling, including a base, a support foot is fixedly installed at the bottom of the base, a control display is fixedly installed on the left side of the top of the base, a transmission support mechanism is arranged at the top of the base, a gear shaft is arranged at the top of the transmission support mechanism, and a detection mechanism is arranged at the top of the base. The transmission support mechanism includes a support assembly and a transmission assembly, the support assembly is arranged at the top of the base, and the transmission assembly is arranged on the inner side of the support assembly. The detection mechanism comprises a support frame, which is fixedly mounted on the top of the base, a sliding member is slidably mounted inside the support frame, a second motor is fixedly mounted on the left side of the base, a threaded rod is fixedly mounted on the output end of the second motor, a mounting frame is fixedly mounted on the right side of the sliding member, a sliding block is slidably mounted inside the mounting frame, a connecting column is fixedly mounted on the bottom of the sliding block, a detection wheel is rotatably mounted on the bottom of the connecting column, a fixing spring is fixedly mounted between the top of the sliding block and the inner side of the top of the mounting frame, and a vibration sensor is fixedly mounted on the top of the sliding block, so as to facilitate the detection of the runout of the gear shaft. The finishing mill cone box installation dynamic balancing test device and auxiliary positioning tooling, through the support assembly and transmission assembly, during use, through the two adjustable sliding frame structures, the spacing of the support wheels on one side can be adjusted accordingly according to the diameter of the gear shaft, and at the same time, the spacing of the support wheels on both sides is ensured to be the same through the sleeve rod and scale rod structure, so as to avoid offset during the rotation process, and the sliding frame drives the adjusting wheel to slide synchronously during the movement process, so that the transmission belt can be adjusted synchronously according to the diameter of the gear shaft, so as to ensure that the transmission belt can stably drive the gear shaft.

[0008] The transmission support mechanism in the above technical solution occupies a large space.

Hold the outer block 311 through the hanging groove 313 and pass it around the bottom of the shaft so that the second belt roller 308 overlaps the second roller frame 304. Adjust the height through the third electric telescopic column 301 so that the belt 307 fits the cone and is tightened.

[0093] S4: Extend the multi-stage electric telescopic rod 402 to make the wireless vibration temperature sensor 403 fit the shaft, start the rotator 306 to drive the first belt roller 305 to rotate, and then drive the shaft to rotate through the belt 307, perform vibration monitoring through the wireless vibration temperature sensor 403, and obtain fault diagnosis results by analyzing the vibration data.

[0094] The working principle of the present invention is as follows:

[0095] The inner frame mechanism 1 is placed into the cone box from the side, and the plate 105 is placed against the wall of the cone box. The inner frame mechanism 1 is initially fixed by clamping the clamping assembly and the wall of the cone box. Then the outer frame mechanism 2 is set up on the outside of the cone box. The two ends of the connecting rod 111 are respectively clamped with the plate 105 and the alignment plate 206, so that the alignment plate 206 and the plate 105 are flush. The position of the bottom block 203 is moved by adjusting the second electric telescopic column 207 to make the positioning rod 204 face the center of the shaft body. The first electric telescopic column 106 is synchronously adjusted according to the adjustment data of the second electric telescopic column 207, so that the ground rail 101 is installed in the cone box facing the shaft body. The external positioning of the outer frame mechanism 2 facilitates the internal positioning of the ground rail 101, so that the placement of the device inside the cone box is more accurate, thereby improving the positioning accuracy.

[0096] The anchor mechanism 6 is placed into the ground rail 101 from the second slide groove 103, and the second belt roller 308 is driven to pass around from the bottom of the shaft body by holding the hanging groove 313, and finally the end of the second belt roller 308 is hung on the second roller frame 304, thereby completing the sleeve connection between the belt 307 and the shaft body. The belt mechanism 3 can be used to sleeve the belt 307 without removing the shaft body from the cone box, which facilitates the fault detection of the cone box.

[0097] The shaft and the belt 307 are sleeved together by wrapping the second belt roller 308 around the bottom of the shaft, and the bottom of the belt 307 is fixed in place in the ground rail 101 in cooperation with the anchor mechanism 6. Subsequently, the height of the first belt roller 305 and the second belt roller 308 can be changed by extending or shortening the third electric telescopic column 301 until the belt 307 is taut. This adjustment can adapt to the sleeve connection of shafts with signals of different sizes inside the cone box, thereby improving the applicability of the device.

[0098] Sliding the third electric telescopic column 301 along the electric rail 201 can change the specific position of the belt 307 sleeved on the shaft, and the sleeve connection of the belt ring 601 and the belt 307 can synchronously change the position of the anchor mechanism 6 in the ground rail 101. When the anchor mechanism 6 is properly positioned, the air pump 501 is started to inflate the interior of the air chamber 604 through the first air pipe 502 and the second air pipe 605, so that the air pressure stabilizes the positioning column 607 and inserts it into the positioning hole 104 to complete the fixing of the anchor mechanism 6. By moving the position of the vibration test assembly, it is convenient to adjust the test position of the shaft, and the test position of the device can be flexibly changed, thereby improving the flexibility of device fault diagnosis.

[0099] Through the air column assembly, when fixation is required, the air pump 501 is started to lock the positioning column 607 through the connection between the first air pipe 502 and the second air pipe 605. When the anchor body mechanism 6 needs to be moved, it is only necessary to slow down the inflation effect of the air pump 501 so that the positioning column 607 can shrink toward the inside of the air chamber 604 under the action of the spring 609, so that the smooth end of the positioning column 607 can be inserted or dislocated when passing through the positioning hole 104, so that it can be more convenient to move in a jerky manner inside the ground rail 101, thereby facilitating the positioning and adjustment of the anchor body mechanism 6 and improving the convenience of adjustment.

[0100] Through the sliding connection between the outer block 311 and the second belt roller 308, the outer block 311 forms a barrier outside the second belt roller 308, which can effectively prevent the belt 307 from falling off when the second belt roller 308 is moved, and through the opening of the hanging groove 313 on the outer block 311, when the internal space of the cone box is relatively narrow, it can be equipped with tools such as hooks and the hanging groove 313 for hanging, so as to facilitate the winding of the second belt roller 308 and the shaft body. In addition, after the second belt roller 308 is hung on the second roller frame 304, the outer block 311 and the second roller frame 304 are matched, which further stabilizes the hanging of the second belt roller 308, making the movement and hanging of the second belt roller 308 more flexible.

[0101] By hanging the belt 307 of the vibration test assembly on one side and the shaft, the vibration test assembly is positioned close to the connection between the shaft and the cone box, and the rotator 306 is started to drive the first belt roller 305 to rotate, thereby driving the shaft to rotate through the belt 307, and analyzing the vibration of the shaft through the wireless vibration temperature sensor 403, so that the connection problem between the shaft and the cone box can be detected; when it is necessary to detect a single gear shaft component in the cone box, it can still be used, and the belt 307 of one vibration test assembly is sleeved on the outside of the gear, and the belt 307 of the other vibration test assembly is sleeved on the outside of the shaft, so that the shaft and the gear are rotated distributedly through the belt 307, and the vibration of the shaft is analyzed through the wireless vibration temperature sensor 403, so that the connection problem between the shaft and the gear can be detected; the position and number of the working vibration test assemblies can be adjusted, so that vibration diagnosis can be performed for various shaft positions and various connection problems of components in the cone box, thereby improving the detection diversity of the device.

[0102] When the connection between the shaft and the cone box is tilted or loose, the use of a single-sided vibration test assembly can prevent the introduction of unnecessary accessories to interfere with the original balance of the shaft, making it easier to detect specific problems. The third electric telescopic column 301 is moved again by the fixed anchor mechanism 6, so that the belt 307 can be transformed from a straight state to a twisted state. When the shaft is connected to the cone box in an uneven manner, the twisted belt 307 can just adapt to the tilt of the shaft, and then determine whether the shaft is properly connected based on the vibration detected by the wireless vibration temperature sensor 403, thereby improving the functionality of the device detection.

[0103] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
