Abstract
Description
Technical Field
[0001] This invention relates to the field of strip steel processing technology, specifically to an instrument for measuring the alignment of rolling lines. Background Technology
[0002] Currently, the alignment of rolling mill lines is measured using the plumb line method. This method is prone to horizontal deviation, making it difficult to guarantee measurement accuracy. Misalignment of the rolling mill line can easily lead to product defects, affecting product quality and on-site production. Therefore, it is essential to develop an instrument for measuring the alignment of rolling mill lines.
[0003] Furthermore, most existing height adjustments are performed directly using lead screws, which still presents the problem that simply using lead screw rotation to drive height adjustment is slow when a large range of laser emitter height needs to be adjusted. Summary of the Invention
[0004] The purpose of this invention is to solve the problems of product defects caused by the inability to align the rolling line of the device, which affects product quality and on-site production, as well as the slow efficiency of simply using the screw rotation to adjust the height when a large range of laser emitter height needs to be adjusted. Therefore, an instrument for measuring the alignment of the rolling line is proposed.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] Design an instrument for measuring the alignment of a rolling mill line, including a base and a leveler. The leveler is set at the upper center of the base. Horizontal support rods are fixed to both the front and rear sides of the inner wall of the base. The four corners of the upper platform of the leveler are fixedly connected to the upper support plate through longitudinal support rods. Laser components are set on the outer walls of the longitudinal support rods. Adjustment components are set on the inner walls of the upper support plate and the base.
[0007] This setting uses a leveler and a bubble mirror to verify whether the instrument is level. When the bubble is in the center of the bubble mirror, the instrument is level. If there is any deviation, it can be leveled using the adjustment knobs at the four corners.
[0008] Preferably, the adjustment assembly includes a horizontal adjustment screw and a height adjustment screw. The two ends of the horizontal adjustment screw are rotatably connected to the base via bearings. The right end of the horizontal adjustment screw is fixedly connected to a horizontal adjustment knob. A sliding platform is threaded onto the outer wall of the horizontal adjustment screw. The two ends of the height adjustment screw are rotatably connected to the upper support plate and the upper platform of the leveler via bearings, respectively. A height adjustment knob is fixedly connected to the upper end of the height adjustment screw.
[0009] This design incorporates multiple adjustment knobs and lead screws, allowing the height of the laser emitter to be adjusted by rotating the lead screw through the height adjustment knob, and the leveling device and sliding platform to be moved horizontally by rotating the horizontal adjustment knob through the horizontal adjustment lead screw.
[0010] Preferably, a leveler is fixedly installed at the upper end of the sliding platform, and adjustment knobs are installed on the inner walls of the four corners of the leveler.
[0011] Preferably, the inner walls of both the front and rear sides of the sliding platform are slidably connected to horizontal support rods. This arrangement, through multiple horizontal support rod structures, restricts the sliding platform to sliding only laterally.
[0012] The laser assembly includes a vertical cylinder and a cylindrical cylinder. The vertical cylinder is threaded to the outer wall of a height adjustment screw. End caps are fixed to both ends of the vertical cylinder. A cylindrical cylinder is slidably connected to the outer wall of the vertical cylinder. Multiple laser emitters are fixed to the upper part of the outer wall of the cylindrical cylinder. The lower front and rear sides of the outer wall of the cylindrical cylinder are fixedly connected to a sliding sleeve via connecting rods. The inner wall of the sliding sleeve is slidably connected to a longitudinal support rod.
[0013] This feature uses the cooperation of a groove and a protrusion to drive the cylinder to slide up and down on the outer wall of the vertical cylinder for rapid position adjustment. After adjusting the outer wall, bolts are used to tighten the cylinder and the vertical cylinder, thus achieving rapid adjustment of the cylinder height.
[0014] Preferably, the inner walls of the left and right sides below the outer wall of the cylinder are threaded with bolts, and the inner walls of the bolts are pressed against the vertical cylinder.
[0015] Preferably, the outer wall of the vertical cylinder is machined with a groove, and the inner wall of the cylindrical cylinder is machined with a protrusion, and the inner wall of the groove is slidably connected to the protrusion.
[0016] This design, through the use of grooves and protrusions, restricts the vertical cylinder from rotating on the inner wall of the cylinder.
[0017] Preferably, a bubble mirror is fixed to the upper right side of the upper support plate.
[0018] The instrument for measuring the alignment of rolling mill lines proposed in this invention has the following advantages:
[0019] Through the cooperation of the longitudinal support rod, upper support plate, adjuster, adjusting screw, adjusting knob, and sliding platform, the height of the laser emitter can be adjusted by rotating the screw through the height adjusting knob. The base, horizontal support rod, leveler, horizontal adjusting screw, and horizontal adjusting knob together form a horizontal moving device. By rotating the horizontal adjusting knob, the horizontal adjusting screw is rotated, thereby moving the leveler and sliding platform horizontally. The advantages of this equipment are that it uses laser to measure the centering of the rolling line, resulting in higher precision and more accurate measurement. The laser emitter can move horizontally and vertically, making the measurement position more accurate. At the same time, this instrument has four laser emitters, which can measure four directions simultaneously, greatly meeting the needs of on-site use.
[0020] The design incorporates a movable cylinder through the interplay of components such as a cylinder, bolts, a sliding groove, a protrusion, a height adjustment screw, a vertical cylinder, and a height adjustment knob. This allows for rapid positional adjustment of the cylinder's height by loosening the bolts, releasing the positional constraints between the cylinder and the vertical cylinder, and then using the sliding groove and protrusion to drive the cylinder to slide up and down on the outer wall of the vertical cylinder for quick position adjustment. After adjusting the outer wall, the bolts are tightened to secure the cylinder and vertical cylinder. Finally, rotating the height adjustment knob drives the height adjustment screw to fine-tune the height of the cylinder and vertical cylinder. This effectively avoids the slow efficiency of simply using a screw to adjust the height of the laser emitter over a wide range. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings:
[0032] See attached document Figure 1-9 In this embodiment, an instrument for measuring the alignment of a rolling mill line includes a base 1 and a leveler 7. The leveler 7 is located at the center of the upper end of the base 1. The model of the leveler 7 can be determined according to specific usage requirements. Horizontal support rods 8 are fixedly connected to both the front and rear sides of the inner wall of the base 1. The four corners of the upper platform of the leveler 7 are fixedly connected to the upper support plate 2 via longitudinal support rods 9. A laser component 4 is provided on the outer wall of the longitudinal support rods 9. Adjustment components 3 are provided on the inner wall of the upper support plate 2 and the inner wall of the base 1. A bubble mirror 5 is fixedly connected to the upper right side of the upper support plate 2. The bubble mirror 5 is a level known in the prior art, and the specific model can be determined according to the usage. Figure 2 The diagram shows two horizontal detection processes: horizontal and vertical.
[0033] See attached document Figure 1-9In this embodiment, the adjustment component 3 includes a horizontal adjustment screw 302 and a height adjustment screw 304. The two ends of the horizontal adjustment screw 302 are rotatably connected to the base 1 via bearings. The right end of the horizontal adjustment screw 302 is fixedly connected to the horizontal adjustment knob 305. Rotation of the horizontal adjustment screw 302 drives the sliding platform 303 to move left and right. The sliding platform 303 is threaded onto the outer wall of the horizontal adjustment screw 302. Rotation of the height adjustment screw 304 drives the cylinder 403 to move up and down. The two ends of the lead screw 304 are rotatably connected to the upper support plate 2 and the upper platform of the leveler 7 respectively through bearings. The upper end of the height adjustment lead screw 304 is fixedly connected to a height adjustment knob 301. The upper end of the sliding platform 303 is fixedly installed with the leveler 7. Adjustment knobs 6 are installed on the inner walls of the four corners of the leveler 7. The height of the four corners can be adjusted by adjusting the adjustment knobs 6, thereby adjusting the upper platform of the overall leveler 7 to be horizontal. The inner walls of the front and rear sides of the sliding platform 303 are slidably connected to the horizontal support rod 8.
[0034] See attached document Figure 1-9 In this embodiment, the laser assembly 4 includes a vertical cylinder 401 and a cylindrical cylinder 403. The vertical cylinder 401 is threaded to the outer wall of the height adjustment screw 304. End caps 407 are fixedly connected to both ends of the vertical cylinder 401. The cylindrical cylinder 403 is slidably connected to the outer wall of the vertical cylinder 401. Multiple laser emitters 404 are fixedly connected to the upper part of the outer wall of the cylindrical cylinder 403. The model of the laser emitters 404 can be determined according to specific usage requirements. The lower front and rear sides of the outer wall of the cylindrical cylinder 403 are fixedly connected to the sliding sleeve 406 via connecting rods 405. The sliding sleeve 406 and the connecting rods 405... 05 allows the cylinder 403 to move only up and down but not rotate, and the inner wall of the sliding sleeve 406 is slidably connected to the longitudinal support rod 9. Bolts 402 are threadedly connected to the inner walls of the left and right sides below the outer wall of the cylinder 403. The inner wall of the bolts 402 abuts against the vertical cylinder 401. The outer wall of the vertical cylinder 401 is machined with a sliding groove 408, and the inner wall of the cylinder 403 is machined with a protrusion 409. The restriction of the sliding groove 408 and the protrusion 409 prevents the vertical cylinder 401 from rotating on the inner wall of the cylinder 403. The inner wall of the sliding groove 408 is slidably connected to the protrusion 409.
[0035] Working principle:
[0036] When this instrument is needed to measure the alignment of the rolling line, first, place the instrument on the corresponding ground or platform. Then, verify the instrument's levelness using the bubble mirror 5. When the bubble is in the center of the bubble mirror 5, the instrument is level. If there is any deviation, adjust it using the four corner adjustment knobs 6. The four longitudinal support rods 9 are fixed together with the upper support plate 2 and the leveler 7 to form a longitudinal adjustment support device.
[0037] The height adjustment screw 304, the height adjustment knob 301 are combined with the sliding sleeve 406 and the connecting rod 405 to fix the four laser emitters 404 on the cylinder 403. The height adjustment screw 304 and the height adjustment knob 301 are assembled on the longitudinal adjustment support device. The height of the laser emitter 404 is adjusted by rotating the height adjustment knob 301 to make the screw rotate.
[0038] The base 1, horizontal support rod 8, leveler 7, horizontal adjustment screw 302, and horizontal adjustment knob 305 are combined to form a horizontal moving device. By rotating the horizontal adjustment knob, the horizontal adjustment screw 302 is rotated, thereby moving the leveler 7 and the sliding platform 303 and the above devices horizontally.
[0039] The advantages of this equipment are that it uses lasers to measure the centering of the rolling line, resulting in higher precision and more accurate measurements. The laser emitter can move horizontally and vertically, making the measurement position more precise. In addition, this instrument has four laser emitters, which can measure four directions simultaneously, greatly meeting the needs of on-site use.
[0040] When a large-scale adjustment of the height of the laser emitter 404 is required, simply using the screw to drive the height adjustment is inefficient. Therefore, this design incorporates a movable cylinder 403. When a large-scale adjustment of the cylinder 403's height is needed, the positional restriction between the cylinder 403 and the vertical cylinder 401 can be released by loosening the bolt 402. Then, through the cooperation of the sliding groove 408 and the protrusion 409, the cylinder 403 is driven to slide up and down on the outer wall of the vertical cylinder 401 for rapid position adjustment. After adjusting the outer wall, the bolt 402 is tightened to fix the cylinder 403 and the vertical cylinder 401. Finally, rotating the height adjustment knob 301 drives the height adjustment screw 304 to fine-tune the height of the cylinder 403 and the vertical cylinder 401. This effectively avoids the problem of slow height adjustment efficiency when a large-scale adjustment of the laser emitter 404's height is required.
[0041] Finally, all the structures appearing in this case, such as the leveler 7, laser emitter 404, bubble mirror 5, and lead screw, are common structures in existing designs. Therefore, their working principles are clear and can fully meet the specific practical requirements.
[0042] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art will understand that various changes in form and detail are possible within the scope of the claims.
