Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and in particular to a roller defect inspection and testing device. Background Technology

[0002] In the process of processing strip steel using a rolling mill, roll marks and scratches are one of the main defects affecting product quality. In the existing technology, the periodic defects of strip steel caused by work roll marks are prominent in multi-roll rolling mills, which seriously affect the product qualification rate.

[0003] The main reasons for defects such as roll marks in rolled strip steel are as follows: Firstly, the roll inspection system is inadequate, and the responsibilities of grinding machine operators and rolling mill operators in roll inspection are unclear, resulting in the problem of "problematic rolls being rolled on the mill." Secondly, no reasonable protective measures were taken when changing the rollers; Thirdly, after slippage or strip breakage occurs during the rolling process, the inspection of the roll system is not comprehensive, and the cleaning inside the stand is inadequate.

[0004] In addition, during the strip steel production process, the discovery of defects in strip steel (rolls) requires manual visual inspection near the production line, which is a cumbersome and dangerous process with poor timeliness in detecting problems.

[0005] Therefore, there is a need for a roll defect inspection and detection device that can effectively record the appearance of the rolls before they are put on the mill, can promptly, safely and efficiently inspect the surface quality of the strip after it is output from the mill and thus infer whether there are defects in the rolls, and can assist in the non-destructive installation of the rolls.

[0023] Example 1

[0024] like Figures 1 to 5 As shown, the roller defect inspection and detection device of this application is located near the rolling mill 001 and includes a limiting bottom rail 100, a top detection component 200, a bottom detection component 300, a power component, and a control unit.

[0025] The limiting bottom rail 100 is positioned on the ground, with its length direction aligned with the axial direction of the rollers of the rolling mill 001, and is located near the exit of the rolling mill 001. The main body of the limiting bottom rail 100 is a horizontally placed long strip of rigid plate, on which multiple long strip-shaped grooves are provided along its own length direction, which can just accommodate the bottom wheels of the top detection component 200 and the bottom detection component 300. After the bottom wheels of the top detection component 200 and the bottom detection component 300 are filled into the long strip-shaped grooves, their free movement is restricted, and they can only move along the length direction of the limiting bottom rail 100.

[0026] The top detection component 200 is used to record the surface condition of the strip steel output from the rolling mill 001, and includes a bottom bearing plate 210, a vertical telescopic support column 220, a horizontal columnar shell 230, an internal drum 260, and a pad 270.

The horizontal columnar shell 230 is a horizontally placed cylindrical shell with an internal space length greater than the width of the strip. One end is fixed to the side of the vertical telescopic support column 220 near the top. A horizontally placed elongated side output port 232 is provided on the side near the rolling mill 001. The side output port 232 is a through slot. The horizontal columnar shell 230 is higher than the strip. The built-in drum 260 is a drum structure, with its axial direction being the same as that of the transverse cylindrical housing 230. It is positioned inside the transverse cylindrical housing 230 and rotates under the coordinated control of the power assembly and the control unit. Figure 5 As shown, the pad 270 is a soft strip, one end of which is fixed to the side wall of the built-in drum 260 and wound around and positioned on the built-in drum 260, and the other end is pointed. The pad 270 is made of rubber and is used to pass through the rolling mill 001 and pad between the roll groups of the rolling mill 001 when the rolls of the rolling mill 001 need to be replaced, to prevent the rolls from colliding and rubbing against each other and causing damage. The bottom of the horizontally placed cylindrical housing 230 is positioned with a bottom guide rail 231; the bottom guide rail 231 is a horizontally placed rigid guide rail, and its length direction is the same as that of the horizontally placed cylindrical housing 230, which is used to guide the sliding shooting component 250 to slide. The sliding camera assembly 250 is a rigid block carrying a camera, which is slidably positioned on the bottom guide rail 231 and slides laterally under the coordinated control of the power assembly and the control unit. During the rolling process, the sliding camera assembly 250 takes photos and / or videos of the strip steel to obtain image information of the strip steel surface. The camera of the sliding camera assembly 250 is connected to the control unit and transmits the obtained image information to the display screen for manual observation and judgment or to the machine vision system for processing and timely issuance of alarm information. The machine vision system is existing technology and will not be described in detail here.

[0027] The bottom detection component 300 is positioned on the limiting bottom rail 100 and includes a base plate 310, a vertical telescopic frame 320 and a horizontal rail 330. The base plate 310 is a horizontally placed rigid plate that serves as a load-bearing structure. It has multiple casters at the bottom, which are omnidirectional wheels. The sum of the length of the base plate 310 and the length of the bottom support plate 210 is less than the length of the limiting bottom rail 100. The vertical telescopic frame 320 is a vertical telescopic rod structure, fixed to the top of the base plate 310 near one end. It extends and retracts under the coordinated control of the power component and the control unit, and is used to drive the horizontal rail 330 to move as needed. The distance between the vertical telescopic frame 320 and the vertical telescopic support column 220 is greater than the width of the strip steel. The transverse rail 330 is a horizontally placed rigid rail with its length direction in the same direction as the width of the strip and located below the strip. A sliding camera component 250 is also positioned on the transverse rail 330. During the rolling process, the sliding camera component 250 takes photos and / or videos of the bottom of the strip to obtain image information of the strip surface.

[0028] The power assembly is used to provide power for the operation of each component of the roller defect inspection and detection device of this application, and the control unit plays the role of controlling the coordinated operation of each component of the roller defect inspection and detection device. Both are existing technologies and will not be described in detail here.

[0029] Preferably, the control unit is a combination of a programmable logic controller and control buttons.

[0030] Furthermore, such as Figure 2 and Figure 4 As shown, a clamping and feeding component is positioned on one side of the horizontal columnar housing 230 near the side output port 232; the clamping and feeding component is used to clamp and feed the pad tape 270 to assist in the stable winding and stable output of the pad tape 270, thereby reducing the amount of manual intervention in the winding and output process of the pad tape 270 and ensuring the stability of the winding and output of the pad tape 270. The clamping assembly includes a bottom support roller 281, a positioning support frame 282, a top roller 283, a rotating carrier frame 284, a vertical telescopic body 285, and a horizontal support frame 286. The bottom support roller 281 is a horizontally placed rigid roller body, which is positioned outside the horizontally placed columnar shell 230 near the side output port 232 by the positioning support frame 282, and its axial direction is the same as the length direction of the side output port 232; the positioning support frame 282 is a rigid support. The top roller 283 is a horizontally placed rigid roller body, positioned outside the horizontally placed cylindrical housing 230 near the side output port 232 by a rotating carrier 284, and located directly above the bottom support roller 281; the rotating carrier 284 is a rigid rod body, one end of which is hinged to the outer wall of the horizontally placed cylindrical housing 230, the axial direction of the hinge shaft is the same as the axial direction of the top roller 283, and the other end is positioned at the end of the top roller 283; the top roller 283 normally abuts against the top of the bottom support roller 281; The vertical telescopic body 285 is a rigid telescopic rod with wheels positioned at the bottom and vertically arranged. It is controlled to extend and retract, located directly above the top roller 283. The bottom wheels abut against the top of the top roller 283, and it is fixed to the outer wall of the horizontal columnar shell 230 by the horizontal support frame 286. The horizontal support frame 286 is a rigid support. At least one of the bottom support roller 281 and the top roller 283 rotates under the coordinated control of the power assembly and the control unit; when it is necessary to wind or output the pad tape 270 from the transverse columnar housing 230, the clamping assembly and the built-in drum 260 work together to move the pad tape 270.

[0031] Preferred, such as Figure 6 As shown, the pad 270 is composed of a layer of metal soft strip and two layers of rubber soft strips disposed at the top and bottom of the metal soft strip.

[0032] When using the roller defect inspection and detection device of this application: Under normal conditions, both the top detection component 200 and the bottom detection component 300 are positioned on the limiting bottom rail 100; Before installing the roller, push the top detection component 200 out of the limiting bottom rail 100, hoist the roller to be installed to the top of the bottom detection component 300, rotate the roller to be installed and use the sliding shooting component 250 to record the appearance of the roller to be installed, so as to facilitate the subsequent division of responsibilities, reduce manual labor, and urge the roller handling personnel to handle the roller properly. Afterward, pull out pad 270 and pass it between the rolling mill roll gaps to reduce damage to the rolls during installation; after installation, recycle pad 270. When performing strip rolling operations, the top detection component 200 and the bottom detection component 300 are both positioned on the limiting bottom rail 100; the two sliding imaging components 250 are controlled to slide back and forth to record the surface image information of the strip and to detect and verify whether there is damage to the rolls of the rolling mill 001.

[0033] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages: This invention solves the technical problems in existing technologies where it is difficult to trace responsibility for roll problems, leading to the frequent occurrence of defective rolls being put into rolling mills. Furthermore, it addresses the issue that detecting roll defects requires manual visual inspection near the production line, which is cumbersome, dangerous, and lacks timely detection. The invention achieves the following technical benefits: the roll defect inspection and detection device can effectively record the appearance of rolls before they are put into rolling mills; it can promptly, safely, and efficiently inspect the surface quality of strip steel after it is output from the mill, thereby inferring whether there are defects in the rolls; and it can assist in the non-destructive installation of rolls.

[0034] Example 2

[0035] Considering that slippage or strip breakage during the rolling process, incomplete inspection of the roll system and inadequate cleaning within the mill stand are also important factors leading to roll damage, and that relying solely on manual visual inspection of the mill 001 is difficult to efficiently determine the cause, with many blind spots and high labor intensity, this application embodiment adds an extension rail 400, improves the side structure of the bottom bearing plate 210, adds a drive gear 110 to the limiting bottom rail 100, adds a top sliding drum 340 to the transverse rail body 330, and simultaneously adds an extension rope 271 to the pad belt 270; specifically: like Figures 7 to 9 As shown, the structure of the extension rail 400 is the same as that of the limiting bottom rail 100, and it is positioned on the ground and near the entrance of the rolling mill 001; the extension rail 400 is provided with a positioning frame 410; the positioning frame 410 is a rigid frame, which is used to detachably fix the bottom detection component 300 as needed. A rack is provided on one side of the bottom support plate 210; the drive gear 110 is positioned at the top of the limiting bottom rail 100 and matches the rack located on one side of the bottom support plate 210. It rotates under the coordinated control of the power component and the control unit, and when rotating, it drives the bottom support plate 210 to reciprocate laterally along the limiting bottom rail 100. The top sliding drum 340 is a horizontally placed rigid drum, positioned on the sliding shooting assembly 250 on the horizontal rail 330, and rotates under the coordinated control of the power assembly and the control unit; the side wall of the top sliding drum 340 is provided with a clamp for fixing the end of the extension rope 271. The tip of the pad 270 is positioned with an extension rope 271; the extension rope 271 is a rubber strip and its length is more than twice the length of the rolling mill 001; one end of the extension rope 271 is fixed to the pad 270.

The bottom detection component 300 is moved and fixed on the positioning frame 410, and the extension of the vertical telescopic frame 320 is adjusted. The extension rope 271 is passed through mill 001 and fixed on the top sliding drum 340. The detachable camera component 273 is installed in the fixed position 272. Subsequently, while controlling the rotation of the rolls of mill 001, the rotation of the drive gear 110, the lateral movement of the top sliding drum 340 on the transverse rail 330, the rotation of the built-in drum 260, and the rotation of the top sliding drum 340 are controlled in coordination, so that the detachable camera component 273 moves between the roll systems and records video to assist the operators in making judgments.
