Description

Technical Field

[0001] The utility model relates to the technical field of roll gap detection of continuous casting machines, in particular to an on-line roll gap gauge for slab continuous casting. Background Technique

[0002] An on-line roll gap gauge for slab continuous casting is a precision instrument used in the steel production process, especially in continuous casting machines, to measure and monitor the roll gap (i.e., the distance between the upper and lower rollers); during continuous casting, accurately controlling the roll gap is crucial for ensuring the quality of the cast slab. If the roll gap is not properly controlled, it may lead to problems such as a decrease in the surface quality of the cast slab and non-compliance with dimensional accuracy, affecting subsequent processing and the performance of the final product; on-line roll gap gauges usually adopt non-contact measurement technologies, such as laser ranging and ultrasonic ranging, which can realize real-time monitoring and adjustment of the roll gap without stopping the production line; this kind of instrument can be integrated into the control system of the continuous casting machine, and automatically adjust the roll gap through a feedback mechanism to ensure the thickness uniformity and dimensional stability of the cast slab, thereby improving production efficiency and product quality.

[0003] For example, the patent with the publication number CN215033428U discloses a new type of multi-functional roll gap gauge, which includes a roll gap gauge body and a guide roll alignment main body. There are two groups of guide roll alignment main bodies, which are symmetrically installed in the roll gap gauge body. The guide roll alignment main body includes a gyroscope sensor module, a PCB board, a waterproof connector, an alignment plate, a substrate, and a tension spring. The gyroscope sensor module, the PCB board, and the waterproof connector are connected in sequence. The gyroscope sensor module and the PCB board are installed in a sensor protective cover. The waterproof connector is clamped on the sensor protective cover. The sensor protective cover is fixedly connected to the alignment plate. The middle parts of both sides of the alignment plate are connected to the substrate through a screw-nut assembly. The alignment plate is provided with waist-shaped holes for cooperating with the screw-nut assembly. The tension springs are symmetrically arranged on both sides of the alignment plate, one end is fixedly connected to the substrate, and the other end hooks the bottom of the side of the alignment plate. Using the gyroscope sensor module can effectively improve the measurement accuracy of the roll gap gauge, and the measurement is sensitive, reliable, and the performance is stable.

[0004] However, the roll gap gauge in the above technology still has the following problems:

[0005] Although the measurement accuracy of the roll gap gauge is improved by using the gyroscope sensor module, during measurement, the sensor of the roll gap gauge needs to be aligned with the roll gap. Otherwise, during measurement, it is easy to generate measurement deviations. When the roll gap gauge is installed, due to the uncertainty of the installation position, the roll gap gauge cannot be quickly installed horizontally, and the angle needs to be continuously adjusted during the installation process, and the installation process is relatively complicated. Summary of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides an on-line roll gap measuring instrument for slab continuous casting, which can quickly realize the horizontal adjustment of the roll gap measuring instrument, quickly complete the installation of the roll gap measuring instrument, and improve the installation efficiency of the roll gap measuring instrument.

[0007] To achieve the above object, the utility model provides the following technical solution: An on-line roll gap measuring instrument for slab continuous casting, including a roll gap measuring instrument body, two symmetrically arranged connecting blocks are fixedly connected to the top of the roll gap measuring instrument body, a flipping assembly is connected between the two connecting blocks, a hoisting assembly is connected to the middle position of the flipping assembly, and a mounting plate is connected to the side of the hoisting assembly away from the flipping assembly.

Detailed Embodiment

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0025] Please refer to Figure 1 - Figure 6 , an on-line roll gap gauge for slab continuous casting, including a roll gap gauge body 1. Two symmetrically arranged connecting blocks 2 are fixedly connected to the top of the roll gap gauge body 1. A flipping component is connected between the two connecting blocks 2. A hoisting component is connected to the middle position of the flipping component. One side of the hoisting component far from the flipping component is connected to a mounting plate 3.

[0026] As Figure 1 - Figure 6As shown, an online roll gap gauge in the present utility model is similar in structure to the existing online roll gap gauges for slab continuous casting, such as a new type of multifunctional roll gap gauge disclosed in the patent with the publication number CN215033428U. The main improvement of the present utility model lies in the ability to achieve rapid and stable installation of the roll gap gauge. For example, Figures 1 to 6 As shown, when the online roll gap gauge for slab continuous casting in the present utility model is in use, the roll gap gauge body 1 is installed and fixed to the installation position through the mounting plate 3. Subsequently, the roll gap gauge body 1 can be adjusted through the hoisting assembly and the flipping assembly, so that under the action of gravity, the roll gap gauge body 1 gradually remains vertical below the mounting plate 3, thereby enabling the laser detector or infrared detector, etc. on the roll gap gauge body 1 to detect the roll gap, achieving the installation efficiency and installation effect of the roll gap gauge body 1.

[0027] For example, Figure 1 - Figure 6 As shown, the flipping assembly includes a cross bar 4. A cavity 401 is provided inside the cross bar 4. Two sets of symmetrically arranged fixing components are connected inside the cavity 401. The two fixing components respectively penetrate through both ends of the cavity 401 and are respectively connected to the two connecting blocks 2. The cross bar 4 is connected and rotated with the two connecting blocks 2 through the two fixing components at the same time. Thus, under the action of gravity, the roll gap gauge body 1 remains in a vertical state. When the roll gap gauge body 1 is vertical and does not swing, the cross bar 4 and the two connecting blocks 2 are fixed through the fixing components, completing the vertical adjustment of the roll gap gauge body 1. It should be particularly noted that the connecting block 2 is on the center line at the top of the roll gap gauge body 1, and the weights of the roll gap gauge body 1 on both sides of the connecting block 2 are the same, so that under the action of gravity, the roll gap gauge body 1 remains perpendicular to the ground.

[0028] For example, Figure 1 - Figure 6 As shown, the fixing component includes an electric push rod 5 and a pressing block 6. The electric push rod 5 is located inside the cavity 401 and is fixedly connected to the cavity 401. The output end of the electric push rod 5 penetrates through the cavity 401 and the adjacent connecting block 2 and is fixedly connected to the pressing block 6. The output end of the electric push rod 5 is rotatably connected to the connecting block 2. After the roll gap gauge body 1 is vertically stable, the electric push rod 5 is started to drive the pressing block 6 to contract inward and press against the connecting block 2, thereby making the connection between the cross bar 4 and the connecting block 2 firm and no longer rotating or swaying, so that the vertical state of the roll gap gauge body 1 is fixed.

[0029] For example, Figure 1 - Figure 6 As shown, an anti-slip ring 7 is fixedly connected to the side of the pressing block 6 close to the connecting block 2. The anti-slip ring 7 abuts against the side of the connecting block 2 away from the cross bar 4. When the pressing block 6 contracts inward, it abuts against the connecting block 2 through the anti-slip ring 7. Thus, after the pressing block 6 is connected to the connecting block 2, the connection between the cross bar 4 and the connecting block 2 is kept fixed, completing the state fixing of the flipping assembly.

[0030] As shown in Figure 1 - Figure 6 As shown, the hoisting assembly includes a hoisting block 8. One side of the hoisting block 8 is fixedly connected to the middle position of the cross bar 4, and the other side of the hoisting block 8 is connected with a tipping assembly, and the tipping assembly is connected with the mounting plate 3. Through the tipping assembly, the cross bar 4, the connecting block 2 and the roll gap gauge body 1 are swung horizontally on the hoisting block 8, and finally under the action of gravity, the roll gap gauge body 1 is kept vertical in the vertical direction and horizontal in the side direction, improving the installation effect of the roll gap gauge body 1. It should be particularly noted that the hoisting block 8 is located at the middle position of the cross bar 4, and the weights on both sides of the hoisting block 8 are the same, so that the roll gap gauge body 1 can be kept horizontal by gravity under the hoisting assembly.

[0031] As shown in Figure 1 - Figure 6 As shown, the tipping assembly includes a U-shaped suspension rod 9 and a tipping block 10. One side of the tipping block 10 is fixedly connected to the side of the hoisting block 8 away from the cross bar 4. Both sides of the tipping block 10 are rotatably connected to the two ends of the U-shaped suspension rod 9 through rotating shafts. The end of the U-shaped suspension rod 9 away from the tipping block 10 is fixedly connected to the mounting plate 3. A motor cavity 901 is opened on the inner wall of the end of the U-shaped suspension rod 9 close to the mounting plate 3, and a positioning assembly is connected in the motor cavity 901. The hoisting block 8 and the tipping block 10 rotate in the U-shaped suspension rod 9 through the rotating shaft and gradually stop swinging under the action of gravity, completing the horizontal holding of the roll gap gauge body 1 below. Subsequently, the connection state of the U-shaped suspension rod 9 and the tipping block 10 is fixed through the positioning assembly, thus completing the installation and fixation of the roll gap gauge body 1.

[0032] As shown in Figure 1 - Figure 6 As shown, the positioning assembly includes an electric telescopic rod 11 and a pressing block 12. The motor part of the electric telescopic rod 11 is located in the motor cavity 901 and is fixedly connected to the motor cavity 901. The telescopic part of the electric telescopic rod 11 penetrates through the motor cavity 901 and is fixedly connected to the pressing block 12. The side of the pressing block 12 away from the electric telescopic rod 11 abuts against the tipping block 10. Start the electric telescopic rod 11 to drive the pressing block 12 to press on the tipping block 10, completing the fixed installation of the roll gap gauge body 1.

[0033] As shown in Figure 1 - Figure 6 As shown, a non-slip sheet 13 is fixedly connected to the side of the pressing block 12 away from the electric telescopic rod 11, and the other side of the non-slip sheet 13 abuts against the tipping block 10. By contacting the non-slip sheet 13 with the tipping block 10, the fixing effect of the tipping block 10 can be further improved.

[0034] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
