Description

Technical Field

[0001] This utility model belongs to the field of testing equipment technology, and in particular relates to an offline simulation rotation testing device for continuous casting rolls. Background Technology

[0002] As a key component in the steel production process, the performance of continuous casting rolls directly affects the quality of cast billets and the stability of the production line. In practical applications, continuous casting rolls typically operate for extended periods under high temperature, high pressure, and high load conditions, making effective inspection and maintenance crucial. However, traditional inspection methods, often relying on manual observation and simple pressure measurements, are not only inefficient but also lack accuracy and reliability. With the steel industry's ever-increasing demands for product quality and production efficiency, traditional methods are no longer sufficient.

[0003] In response, CN219924501U discloses a novel three-section roller water testing device for the sector section of a slab continuous casting machine to replace the existing manual testing method. However, in the above patent, only one continuous casting roller can be tested at a time. If a comparative experiment is to be carried out under different working conditions, the data can only be measured under different working conditions and then compared, which is cumbersome. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a rotary testing device that can directly test two continuous casting rolls under different working conditions at once.

[0005] The objective of this utility model can be achieved through the following technical solution: an offline simulation rotation testing device for continuous casting rolls, comprising:

[0006] Work plane;

[0007] Two sets of support components and two sets of support frames are located on the working plane. Each set of support components includes a row of multiple support seats arranged at linear intervals. The two rows of support seats are arranged in parallel directions. The support seats are used to support the continuous casting roll support, and each support seat is also provided with a clamping component for fixing the continuous casting roll support.

[0008] A drive unit, comprising a drive wheel, with a gap between two sets of support members forming a receiving space, the drive wheel being located within the receiving space, and the position of the drive wheel being adjustable in the vertical direction;

[0009] The drive wheel can simultaneously contact and connect with the continuous casting roll sleeves on the two sets of support members, driving the two sets of continuous casting rolls to rotate simultaneously for synchronous testing.

[0010] In the above-mentioned offline simulation rotation test device for continuous casting rolls, the drive wheel is located at the middle position of the support member along the length extension direction of the support member.

[0011] In the above-mentioned offline simulation rotation test device for continuous casting rolls, when the support is fixedly connected to the continuous casting roll, the drive wheel is located below the continuous casting roll.

[0012] In the above-mentioned offline simulation rotation test device for continuous casting rolls, an adjusting screw is rotatably connected below the working plane, and the driving unit also includes a driving component that is driven and connected to the driving wheel. The driving component can only move linearly in the vertical direction, and the driving component is screwed to the adjusting screw.

[0013] In the above-mentioned offline simulation rotation test device for continuous casting rolls, the first end of the adjusting screw is threadedly connected to the driving component, and the second end of the adjusting screw is provided with an adjusting operation part.

[0014] In the above-mentioned offline simulation rotation test device for continuous casting rolls, a limiting block is fixedly arranged below the working plane, the upper end of the limiting block is provided with an opening, a limiting cavity extending vertically is provided inside the limiting block, and the limiting cavity is connected to the opening, the lower end of the driving member is located inside the limiting cavity and abuts against the cavity wall of the limiting cavity, and the driving member can slide relative to the limiting cavity; the adjusting screw is rotatably connected to the lower end of the limiting block.

[0015] In the above-mentioned offline simulation rotation test device for continuous casting rolls, a connecting column is provided at the lower end of the driving component. The cross-sectional area of ​​the connecting column is smaller than that of the driving component. The connecting column extends into the limiting cavity, and the adjusting screw is threadedly connected to the connecting column. Furthermore, the straight-line distance between the rotation axis of the driving wheel and the lower end of the driving component is greater than the radius of the driving wheel.

[0016] In the above-mentioned offline simulation rotation test device for continuous casting rolls, there are two drive wheels, which are symmetrically arranged on both sides of the drive component.

[0017] In the above-mentioned offline simulation rotation test device for continuous casting rolls, water baffles are provided around the working plane, and water outlets on the water baffles are connected to the water storage tank.

[0018] In the above-mentioned offline simulation rotation test device for continuous casting rolls, a pressure gauge and a flow meter are provided on the working plane and connected to the test water circuit.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: the rotating testing device can simulate the online working conditions of the continuous casting roll in an offline state. The drive wheel is allowed to contact the continuous casting rolls on the two sets of support members at the same time and drive them to rotate. This not only ensures the consistency and accuracy of the test, but also allows for direct comparison of the performance of the same continuous casting roll under different working conditions, providing a basis for optimization selection.

Detailed Implementation

[0026] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0028] like Figures 1-5 As shown, an offline simulation rotation testing device for continuous casting rolls includes:

[0029] Working plane 100;

[0030] Two sets of support components and two sets of support frames are located on the working plane 100. Each set of support components includes a row of multiple support seats 200 arranged at linear intervals. The two rows of support seats 200 are arranged in parallel directions. The support seats 200 are used to support the continuous casting roll 400 support, and each support seat 200 is also provided with a clamping part for fixing the continuous casting roll 400 support.

[0031] The drive unit includes a drive wheel 300. A gap is provided between two sets of support members to form a receiving space. The drive wheel 300 is located in the receiving space. The position of the drive wheel 300 in the vertical direction is adjustable.

[0032] Among them, the drive wheel 300 can simultaneously contact and connect with the continuous casting rolls 400 sleeves on the two sets of support members, driving the two sets of continuous casting rolls 400 to rotate simultaneously for synchronous testing.

[0033] In this embodiment, the rotating testing device enables the continuous casting roll 400 to be tested under simulated online working conditions while offline. The drive wheel 300 is allowed to contact and drive the continuous casting rolls 400 on the two sets of support members to rotate simultaneously. This not only ensures the consistency and accuracy of the test, but also allows for direct comparison of the performance of the same continuous casting roll 400 under different working conditions, providing a basis for optimization selection.

[0034] It is worth mentioning that the drive wheel 300 can simultaneously contact and drive two sets of continuous casting rolls 400 to rotate. However, each set of continuous casting rolls 400 has its own independent water circuit test channel. Therefore, at the same speed, the same water flow with the same test parameters such as pressure and flow rate can be provided to the two sets of continuous casting rolls 400 to increase the test effect of the continuous casting rolls 400. Alternatively, different test parameters such as pressure and flow rate can be provided to the two sets of continuous casting rolls 400 to compare their working performance at the same speed.

[0035] Preferably, the drive wheel 300 is located at the middle of the support along the length of the support.

[0036] In this embodiment, the drive wheel 300 is located in the middle of the support, ensuring that the driving force on the continuous casting roll 400 during the test can be evenly distributed along the entire length of the continuous casting roll 400. This avoids the phenomenon of uneven load caused by the driving force being concentrated at one end, and reduces wear and potential failure risks caused by uneven load. This arrangement makes the forces on both ends of the continuous casting roll 400 more balanced, reduces vibration and jumping, and thus ensures the stability and accuracy of the test process.

[0037] More preferably, when the support is fixedly connected to the continuous casting roll 400, the drive wheel 300 is located below the continuous casting roll 400, so that the continuous casting roll 400 can naturally press on the drive wheel 300, ensuring good contact; this layout effectively utilizes vertical space, reduces the overall footprint of the equipment, and is particularly suitable for applications in limited spaces in factory environments.

[0038] In a further preferred embodiment, an adjusting screw 103 is rotatably connected below the working plane 100, and the drive unit also includes a drive component 301 that is drivenly connected to the drive wheel 300. The drive component 301 can only move linearly in the vertical direction, and the drive component 301 is screwed to the adjusting screw 103.

[0039] In this embodiment, by providing a rotatably connected adjusting screw 103 below the working plane 100 and screwing the driving member 301 to the adjusting screw 103, the driving wheel 300 can be precisely adjusted in the vertical direction, allowing the driving wheel 300 to adapt to continuous casting rolls 400 of different diameters, ensuring that the driving wheel 300 can always contact the continuous casting roll 400 in the best contact state.

[0040] It is worth mentioning that a connecting part is provided under the drive component 301 for supporting connection.

[0041] More preferably, the first end of the adjusting screw 103 is threadedly connected to the drive member 301, and the second end of the adjusting screw 103 is provided with an adjusting operation part 107.

[0042] In this embodiment, by adjusting the threaded connection between the lead screw 103 and the drive member 301, the operator can achieve precise vertical movement of the drive member 301 by rotating the lead screw 103; the second end of the lead screw 103 is provided with an adjustment operation part 107 (such as a handwheel or knob), which allows the operator to easily make manual adjustments without using additional tools, thus simplifying the operation process and improving work efficiency.

[0043] Specifically, a limiting block 101 is fixedly installed below the working plane 100. The upper end of the limiting block 101 is provided with an opening. A limiting cavity 102 extending vertically is provided inside the limiting block 101, and the limiting cavity 102 is connected to the opening. The lower end of the driving member 301 is located inside the limiting cavity 102 and abuts against the cavity wall of the limiting cavity 102. The driving member 301 can slide relative to the limiting cavity 102. The adjusting screw 103 is rotatably connected to the lower end of the limiting block 101.

[0044] More preferably, the lower end of the driving member 301 is provided with a connecting post 302, the cross-sectional area of ​​the connecting post 302 is smaller than the cross-sectional area of ​​the driving member 301, the connecting post 302 extends into the limiting cavity 102, and the adjusting screw 103 is threadedly connected to the connecting post 302; and the straight distance between the rotation axis of the driving wheel 300 and the lower end of the driving member 301 is greater than the radius of the driving wheel 300.

[0045] It should be noted that the upper end of the limit block 101 is flush with the working plane 100.

[0046] In this embodiment, by providing a connecting post 302 with a small cross-sectional area at the lower end of the driving member 301 and allowing the connecting post 302 to extend into the limiting cavity 102, the driving member 301 can slide more smoothly and accurately within the limiting cavity 102. Moreover, the presence of the connecting post 302 reduces the friction area, lowers the risk of wear, and ensures the directionality of the driving member 301 during movement. Furthermore, the straight-line distance between the rotation axis of the driving wheel 300 and the lower end of the driving member 301 is greater than the radius of the driving wheel 300. This ensures that when the driving member 301 abuts against the limiting block 101, there is still a gap between the driving wheel 300 and the working plane 100. That is, when the driving wheel 300 moves down to its limit position, the driving wheel 300 will not contact the working plane 100, thus avoiding accidental collision damage caused by the driving wheel 300 abutting against the working plane 100.

[0047] Preferably, there are two drive wheels 300, which are symmetrically arranged on both sides of the drive component 301. This avoids the off-center load phenomenon caused by unilateral drive, reduces the vibration or jumping of the continuous casting roll 400 during the test, and improves the stability and accuracy of the test process. Using two drive wheels 300 increases the number of contact points with the continuous casting roll 400, providing more stable support. Even if one drive wheel 300 experiences slight slippage or other problems, the other drive wheel 300 can still maintain effective driving force, improving the reliability and fault tolerance of the system.

[0048] like Figure 4 As shown, in a further preferred embodiment, a water-blocking plate 104 is provided around the working plane 100, and a water outlet is provided on the water-blocking plate 104 that is connected to the water storage tank.

[0049] In this embodiment, when the continuous casting roll 400 is removed after testing, there may still be liquid remaining inside the continuous casting roll 400. This liquid will drip onto the working surface 100. In order to prevent this liquid from sliding down the working surface 100 and causing environmental pollution, an L-shaped baffle is provided around the working surface 100 to block the liquid on the working surface 100.

[0050] It is worth mentioning that a water-blocking ring is also provided on the working plane 100 at the opening of the limiting block 101.

[0051] like Figure 5 As shown, in a further preferred embodiment, a pressure gauge 105 and a flow meter 106 are provided on the working plane 100 and connected to the test water circuit.

[0052] In this embodiment, the pressure of the cooling water can be monitored in real time by means of the pressure gauge 105 connected to the test water circuit, and the flow meter 106 can accurately measure the amount of water flowing through the test water circuit. This is very useful for evaluating the efficiency of the cooling system and detecting whether there are blockages or leaks. By monitoring the flow rate changes, potential problems can be discovered and resolved in a timely manner.
