Description

Technical Field

[0001] This utility model relates to the technical field of bearing housing lubrication and oil supply devices, specifically to an offline intelligent lubrication and oil supply device for hot-rolled strip steel roll bearing housings. Background Technology

[0002] In the hot-rolled strip steel production process, the rolls, as the core rolling components, directly determine the product quality and production efficiency of the strip steel through their operational stability. The lubrication status of the roll bearing housings is a key factor in ensuring the reliable operation of the rolls. During operation, the roll bearing housings must withstand enormous rolling forces, impact forces, and high operating temperatures. If lubrication is untimely, insufficient, or the lubricating grease is of insufficient purity, it can easily lead to bearing wear, burnout, and other malfunctions. This not only results in serious consequences such as roll scrapping and equipment downtime but also significantly increases production and maintenance costs, hindering the smooth progress of production plans.

[0003] Currently, offline lubrication of hot-rolled strip steel roll bearing housings is mostly done manually, where operators add lubricating grease to the bearing housing using a manual oil pump or simple lubrication equipment. This traditional method has several drawbacks: First, lubrication precision is difficult to control. The amount of oil added manually depends entirely on the operator's experience, which can easily lead to waste due to excessive oil or lubrication failure due to insufficient oil. Furthermore, it is impossible to accurately control the oiling pressure, which may damage the bearing's sealing structure due to improper pressure. Second, the purity of the lubricating grease cannot be guaranteed. During manual lubrication, the grease is easily contaminated by dust, iron filings, and other impurities on site. Once inside the bearing housing, this contamination can accelerate bearing wear and shorten its service life. Utility Model Content

[0004] Technical problems to be solved In view of the above-mentioned shortcomings of the existing technology, the present invention provides an offline intelligent lubrication and oil supply device for hot-rolled strip steel roll bearing housing, which can effectively solve the problems in the existing technology.

[0005] Technical solution This utility model provides an offline intelligent lubrication device for hot-rolled strip steel roll bearing housing, including an oil storage tank. One end of the oil storage tank is connected to a one-way valve via a dry oil pump. The bottom end of the one-way valve is connected to a filter. The bottom end of the filter is connected to an oiling hose via a flow detection device. The other end of the oiling hose is connected to a work roll bearing housing. A work roll is fitted inside the work roll bearing housing. The other end of the filter is connected to an overflow valve. A compressed air purging assembly is provided at the front end of the work roll bearing housing. Multiple sets of monitoring cameras are fixed at the lubrication operation site.

[0006] Furthermore, one end of the dry oil pump is driven by a motor.

[0007] Furthermore, a pressure gauge is connected to the front end of the overflow valve.

[0008] Furthermore, one end of each of the dry oil pump, motor, compressed air purging assembly, and monitoring camera is electrically connected to the electrical control cabinet via a computer system.

[0009] Furthermore, the working roller bearing housing is provided with a quick-connect sealing joint, and one end of the quick-connect sealing joint is threadedly connected to the bearing housing.

[0010] Beneficial effects This invention redesigns the offline intelligent lubrication and oiling device for rolling mills, achieving high efficiency, high quality, safety, economy, and intelligence in oiling operations. This meets the intelligent management needs of modern steel rolling workshops and solves the problems of low efficiency, significant safety hazards, and lack of management associated with traditional manual oiling devices.

[0011] Simultaneously, the filter in this device effectively filters the lubricating grease, removing impurities and ensuring the purity of the grease entering the bearing housing. This significantly reduces the risk of bearing wear due to impurities and extends the service life of the rolls and bearings. The combination of the relief valve and pressure gauge allows for real-time monitoring of the oil circuit pressure. When the pressure exceeds a set threshold, the relief valve automatically opens to release pressure, preventing damage to the bearing housing sealing structure and internal components due to excessive pressure, further enhancing the safety of lubrication operations.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0016] The present invention will be further described below with reference to the embodiments.

[0017] Example: An offline intelligent lubrication and oil supply device for hot-rolled strip steel roll bearing housing, as shown in the attached document. Figure 1 -Appendix Figure 2 It includes an oil storage tank 1, one end of which is connected to a one-way valve 4 via a dry oil pump 2. The bottom end of the one-way valve 4 is connected to a filter 5. The bottom end of the filter 5 is connected to an oiling hose 10 via a flow detection device 6. The other end of the oiling hose 10 is connected to a working roller bearing seat 11. A working roller is fitted inside the working roller bearing seat 11. The other end of the filter 5 is connected to an overflow valve 7. A compressed air purging assembly 12 is provided at the front end of the working roller bearing seat 11. Multiple sets of monitoring cameras 13 are fixed at the oiling operation site. One end of the dry oil pump 2 is driven by the motor 3. This device provides stable power to the dry oil pump 2 via the motor 3. The oil pump integrates a high-pressure plunger pump group and a dynamic pressure compensation system to ensure stable system pressure and provide reliable power for efficient oil injection. The check valve 4 ensures the uniqueness of the grease delivery direction, preventing backflow. The flow detection device 6 can monitor the oil supply in real time. Combined with the coordinated control of the computer system 14 and the electrical control cabinet 8, it can accurately adjust the oil supply and pressure according to the lubrication requirements of the bearing housing, completely solving the problem of inaccurate oil quantity and pressure control in traditional manual oiling. Simultaneously, the filter 5 effectively filters the lubricating grease, removing impurities and ensuring the purity of the grease entering the bearing housing. This significantly reduces the risk of bearing wear due to impurities and extends the service life of the rolls and bearings. The combination of the overflow valve 7 and the pressure gauge 9 allows for real-time monitoring of the oil circuit pressure. When the pressure exceeds the set threshold, the overflow valve 7 automatically opens to release pressure, preventing damage to the bearing housing sealing structure and internal components due to excessive pressure, further improving the safety of lubrication operations.

[0018] The overflow valve 7 is connected to a pressure gauge 9 at its front end. The device adopts a fully automated operation mode, and the computer system 14 can realize one-button control of core components such as the dry oil pump 2 and motor 3, eliminating the need for operators to manually pressurize and supply oil repeatedly. The quick-connect sealing joint set on the working roller bearing housing 11 enables quick docking between the oiling hose 10 and the bearing housing, significantly shortening the connection time and improving efficiency compared to the traditional threaded connection method. At the same time, the quick-connect sealing joint enables quick docking of the bearing housing plug without disassembly, significantly shortening the oiling time of a single bearing box and significantly improving work efficiency. During operation, first clean the bearing housing interface and the surface of the quick-connect sealing joint to ensure that there is no oil or impurities. Then, align the quick-connect sealing joint with the bearing housing interface and gently insert it. A "click" sound indicates that the connection is successful and the sealing docking is completed. The docking operation time of a single bearing box can be controlled within 1-2 minutes, which significantly shortens the oiling preparation time compared to the traditional method and significantly improves work efficiency. After lubrication, press the unlock button on the quick-connect sealing joint to easily separate the joint from the bearing housing.

[0019] The system employs a long-distance, multi-layered, steel-braided Teflon-reinforced oiling hose 10. This hose is lightweight and has high pressure resistance, reducing the need for frequent roller lifting operations, lowering manual labor intensity, and making operation more convenient. The hose's laying path is rationally planned according to the layout between the grinding rollers and the position of the work roller transport track, minimizing bending and tangling to reduce resistance. During use, due to the hose's low weight and high pressure resistance, operators do not need to frequently use cranes to lift the work rollers to the oiling device; oiling can be performed directly at the current position of the work roller. After oiling, the hose is properly stored to avoid compression and wear, extending its service life. Simultaneously, the automated operation mode can accommodate the lubrication needs of multiple bearing seats, and with the on-site monitoring camera 13, multi-station parallel monitoring is achieved, reducing manual intervention. This not only lowers the labor intensity of operators but also reduces the number of on-site workers, lowering labor costs and adapting to the efficient maintenance rhythm of modern production lines.

[0020] One end of the dry oil pump 2, motor 3, compressed air purging assembly 12, and monitoring camera 13 are all electrically connected to the electrical control cabinet 8 via computer system 14. A quick-connect sealing joint is installed in the work roller bearing housing 11, and one end of this quick-connect sealing joint is threadedly connected to the bearing housing. The compressed air purging assembly 12 installed at the front end of the work roller bearing housing 11 can clean the bearing housing interface and surrounding area before oiling operations, removing dust, iron filings, and other impurities to prevent impurities from entering the bearing housing with the lubricating grease. It can also blow away residual grease from the interface after oiling, keeping the work site clean. The introduction of compressed air purging devices cleans the hoses and bearing housing quick connectors, effectively preventing impurity contamination and reducing the risk of bearing damage. The multiple monitoring cameras 13, in conjunction with the computer system 14, enable real-time visual monitoring of the entire oiling operation process. Operators can view the operation status via a remote terminal, promptly detect and handle abnormal situations during the oiling process, eliminating the need for continuous monitoring in high-temperature, dusty environments and improving operational safety. In addition, all core components of the device are linked with the computer system 14, which can realize the real-time acquisition and storage of operation data, facilitate the subsequent traceability analysis of lubrication operation quality, provide data support for equipment maintenance, and integrate remote control and quantitative functions for the oil pump.

[0021] Operators can remotely start and stop the grease pump using a dedicated remote control. Before starting grease injection, the operator sets a quantitative grease injection value in the grease pump control system based on the grease requirements of each bearing housing. When the grease injection volume reaches the set value, the grease pump automatically stops working, achieving precise control of the grease injection volume. Compared to traditional manual grease injection, this reduces grease waste by approximately 10-15%. Simultaneously, during the grease injection process, the operator can monitor the grease injection status in real time via the remote control and immediately stop the grease injection operation if any abnormality is detected.

[0022] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
