[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. The specific structures and functional details disclosed herein are only used to describe the exemplary embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments set forth herein.

[0028] The coiler roller drive system of continuous casting and rolling is a key component of the continuous casting and rolling production line. The function of the coiler roller drive system is to control the exit tension of the rolling mill and roll the strip into a coil.

[0029] The full name of SWC universal joint is SWC cross-shaft universal joint, which is a mechanical part used to connect two shafts (driving shaft and driven shaft) in different mechanisms to transmit torque.

[0030] The integral fork of the SWC universal joint has no bolt connection, which avoids the problem of bolt loosening or breaking, improves the reliability and service life of the connection, and has a large angle compensation capability. The SWC axis angle can reach 15° to 25°. The SWC universal joint has a compact and reasonable structure and a large load-bearing capacity. Compared with other types of couplings with the same swing diameter, the SWC universal joint can transmit greater torque.

[0031] like Figure 1 As shown, Figure 1 A structural perspective view of a connecting member 100 and a protective member 200 provided in an embodiment of the present application, a coiling roller transmission system for continuous casting and rolling, to improve the stability and safety of the continuous casting and rolling production line, the coiling roller transmission system includes a transmission member, a connecting member 100 and a protective member 200, to ensure that the transmission cardan shaft operates reliably under a high temperature and high pressure working environment, wherein:

[0032] The transmission member comprises a transmission universal joint shaft and a cross bag which are connected to each other, and a stable connection and power transmission are achieved through the transmission universal joint shaft and the cross bag.

[0033] The connecting member 100 is used to be connected to one end of the transmission universal joint shaft close to the cross bag, and the connecting member 100 is stably installed by using the connecting area on the universal joint shaft as an installation base.

[0034] like Figure 1 As shown, the protective member 200 is fixedly connected to one side of the connecting member 100, and the protective member 200 has a protective section for blocking the cross bag. The protective member 200 is provided with a first opening 201 on one side facing the cross bag, and a first gap is provided between the protective member 200 and the cross bag.

[0035] The protective member 200 protects the working area where the cross bag is located from damage caused by high temperature, splashing metal droplets and cooling water immersion. The protective member 200 is fixedly connected to one side of the connecting member 100 to form a solid protective barrier. The protective member 200 has a special protective section that can be blocked on the cross bag, thereby providing stable protection for the target area.

[0036] like Figure 1 , Figure 2 as well as Figure 3 As shown, Figure 2 A side view of a connecting member 100 and a protective member 200 provided in an embodiment of the present application. Figure 3 This is a front view of the connecting member 100 and the protective member 200 provided in the embodiment of the present application. A first opening 201 is provided on the side of the protective member 200 facing the cross bag. On the one hand, the protective member 200 does not hinder the normal operation of the cross bag area while providing protection, allowing the cross bag to move and rotate freely during the continuous casting and rolling process without being hindered by the protective member 200. On the other hand, the protective member 200 can be installed toward the cross bag through the first opening 201 during the installation operation, and the installation is performed under the premise of keeping the universal shaft stably connected, thereby improving the assembly efficiency and avoiding the disassembly of the transmission component.

[0037] A first gap is preset between the protective member 200 and the cross bag. The control of the first gap can be reserved by installing the connecting member 100. After the connecting member 100 is installed in a fixed position and the relative position of the connecting member 100 and the protective member 200 is kept stable, the first gap can be stably maintained. The existence of the first gap ensures that there is enough space between the protective member 200 and the cross bag to avoid unnecessary contact and friction under high temperature and high pressure working conditions. The first gap helps to reduce heat accumulation and pressure increase, protecting the entire transmission system from damage.

[0038] In an optional embodiment, the present application uses a winding roller transmission system for continuous casting and rolling operations. The working principle of the winding roller transmission system is: the winding roller transmission system includes a connecting member 100 and a protective member 200. The connecting member 100 is used to connect to one end of the transmission universal joint near the cross bag. The protective member 200 is fixedly connected to one side of the connecting member 100, and the protective member 200 has a protective section for blocking the cross bag. The protective member 200 is provided with a first opening 201 on the side facing the cross bag, and a first gap is provided between the protective member 200 and the cross bag. During actual operation, the protective member 200 is connected to one end of the universal joint through the connecting member 100. The guard 200 is kept extending above the cross bag, and the guard 200 is stably kept in the relative position, and effectively prevents the cooling water from splashing onto the position of the universal shaft cross bag during the production of the curling machine, forming a barrier for the cooling water and guiding its discharge, thereby improving the working environment of the universal shaft cross bag and solving the problem of the short service life of the universal shaft. The installation and connection basis of the connector 100 does not require damage or modification of the original auxiliary rolling roller transmission system, and the overall cost and operation difficulty are low. At the same time, the first opening 201 is used to maintain the convenience of assembly between the cross bag, and the reserved first gap keeps the guard 200 from interfering with the movement trajectory of the universal shaft when providing protection operations, and the overall reliability is strong.

[0039] like Figure 1 , Figure 3 As shown, in an optional embodiment, the cross-section of the protective member 200 is C-shaped, and the first opening 201 penetrates the protective member 200 along the length direction of the protective member 200 .

[0040] In an optional embodiment, the cross-section of the protective member 200 is in the shape of a C-shaped cylinder. This C-shaped cylinder design not only provides strong structural stability, but also allows the protective member 200 to maintain sufficient flexibility and adaptability while protecting the connector 100.

[0041] The C-shaped cylindrical protection member 200 also optimizes space utilization. Due to the hollow center portion of the protection member 200, the protection member 200 can provide a larger protection area without adding too much weight, which is of great significance for reducing the weight of the entire system and improving energy efficiency, and also improves the reliability of the connector 100.

[0042] The first opening 201 runs through the entire protective member 200 along the length direction of the protective member 200. This design allows the protective member 200 to protect the connector 100 while not hindering the normal operation of the cross bag. The existence of the first opening 201 allows the cross bag to move and rotate freely during the continuous casting and rolling process, ensuring the continuity and efficiency of production.

[0043] Considering the complex working conditions of the protective member 200 , the protective member 200 may be made of high temperature resistant and wear resistant materials, such as alloy steel or high strength composite materials, to ensure durability and reliability under extreme conditions.

[0044] In addition, the C-shaped cylindrical protective member 200 allows for quick installation and disassembly, is convenient for maintenance and replacement, simplifies maintenance work, and maintenance personnel can easily check and clean the inside of the protective member 200 to promptly discover and solve problems.

[0045] like Figure 1 , Figure 3 As shown, in an optional embodiment, the width of the first opening 201 is not less than the outer diameter of the transmission universal joint shaft and the outer diameter of the cross bag, ensuring that the cross bag can reciprocate at the first opening 201 compared to the protective member 200 to maintain installation reliability.

[0046] like Figure 1 , Figure 3 As shown, in an optional embodiment, the central angle of the first opening 201 is not less than 200°, and the central angle of the first opening 201 corresponds to the adjacent Figure 3 The central angle of the first opening 201 is not less than 200°, which means that the first opening 201 of the protective member 200 occupies most of the circumference corresponding to the C-shaped cross-section of the protective member 200, so that a wider space can be provided at the first opening 201. Under the premise of maintaining reliable protection for the cross bag area, the operation of the cross bag in the continuous casting and rolling process is more flexible.

[0047] In addition, the opening angle constraint of the first opening 201 helps to reduce stress concentration points, thereby reducing the risk of fracture or deformation of the protective member 200 under high-load working conditions.

[0048] like Figure 1 , Figure 3 As shown, in an optional embodiment, the connecting member 100 is in an open ring shape, and is provided with a second opening 101 for accommodating the universal shaft to pass through, and the width of the second opening 101 is not less than the outer diameter of the universal shaft.

[0049] like Figure 1 , Figure 3 As shown, in an optional embodiment, the angle of the central angle corresponding to the second opening 101 is equal to the angle of the central angle corresponding to the first opening 201 , so as to maintain the consistency between the connecting member 100 and the protective member 200 .

[0050] like Figure 1 , Figure 3As shown, in an optional embodiment, a plurality of mounting holes 102 are provided through the connecting member 100, and the mounting holes 102 correspond to the connecting holes on the end cover of the transmission universal joint shaft. The connecting bolts on the end cover can pass through the mounting holes 102 to connect the connecting member 100, so as to enhance the connection stability and installation convenience between the connecting member 100 and the transmission universal joint shaft.

[0051] The multiple mounting holes 102 provided on the connector 100 provide flexible mounting options, allowing adjustments according to different installation requirements and conditions, increasing the adaptability and versatility of the system, and allowing the connector 100 to be adapted to various types of universal joints.

[0052] The mounting hole 102 corresponds to the connection hole on the end cover of the transmission universal joint shaft. This precise correspondence ensures the correct alignment between the connecting member 100 and the universal joint shaft, reduces errors during the installation process, and improves the accuracy and reliability of the connection.

[0053] By threading and tightening the connecting bolts, the relative position between the connecting member 100 and the universal shaft can be adjusted to adapt to different installation angles and torque requirements. This adjustment capability is crucial to ensuring the dynamic balance of the transmission system and reducing vibration.

[0054] The plurality of mounting holes 102 effectively disperse the stress between the connecting member 100 and the universal shaft, thereby enhancing the strength and stability of the entire connecting structure.

[0055] The connector 100 is provided with a plurality of mounting holes 102, which, combined with the connection bolts on the base end cover of the transmission system, provide an efficient, stable and easy-to-maintain connection method. This not only improves the installation efficiency and operation stability of the continuous casting and rolling auxiliary roll transmission system, but also enhances the adaptability and reliability, and is an important technical choice for improving the performance and safety of the production line.

[0056] like Figure 2 , Figure 4 As shown, Figure 4 The attached embodiment of the present application provides Figure 2 In the partially enlarged schematic diagram at point A, in an optional embodiment, a reinforcing rib 103 is provided between the connecting member 100 and the protective member 200 to further improve the connection stability between the connecting member 100 and the protective member 200.

[0057] like Figure 2 , Figure 4 As shown, in an optional embodiment, the connecting member 100 and the protective member 200 are fixed by welding, or other fixing methods can be used to keep the protective member 200 accurately arranged on the target area when the connecting member 100 is assembled and installed.

[0058] In an optional embodiment, the connecting member 100 and the protective member 200 are respectively made of stainless steel, galvanized steel or copper alloy.

[0059] The connector 100 and the protective member 200 are made of stainless steel, galvanized steel or copper alloy. Stainless steel is resistant to corrosion from a variety of media, including humid environments, saline solutions, etc. Stainless steel has high strength and durability, can withstand long-term impact and wear, and maintain structural integrity. Stainless steel has a smooth surface, is easy to clean and maintain, and is suitable for exposure to external environments.

[0060] Galvanized steel improves corrosion resistance by coating the steel surface with a layer of zinc. The zinc layer acts as a sacrificial anode to protect the underlying steel from corrosion. Galvanized steel is relatively low in cost and provides good corrosion resistance. Galvanized steel can be easily processed by cutting, bending and welding, and is suitable for various complex structural designs.

[0061] Copper alloys have excellent electrical and thermal conductivity. While maintaining good ductility, they also exhibit high strength and wear resistance, making them suitable for carrying heavy loads and high-frequency use. Copper alloys can maintain stable performance in high-temperature environments and are suitable for industrial applications that require high-temperature resistance.

[0062] In summary, stainless steel, galvanized steel and copper alloy are selected as materials for the connector 100 and the protective member 200 to meet the requirements of different industrial applications. The most suitable material can be selected according to the specific application environment, cost budget and performance requirements.
