[0033] In summary, the present application has the following beneficial effects:

[0034] 1. An efficient and intelligent lubrication and anti-corrosion system. The design of the supply pipe and the return pipe in the lubricating oil conduit, combined with the spiral isolation layer, realizes the efficient circulation of the lubricating oil. The micro-holes precision machined by laser on the supply pipe adopt a gradually changing aperture design to ensure the uniform distribution of the lubricating oil at different parts of the wire rope. The 316L stainless steel lubricating oil conduit and the oil-repellent nano-coating improve the corrosion resistance and circulation efficiency of the system.

The heating strip integrates heating, temperature monitoring, and stress monitoring functions. It uses a nickel-chromium alloy substrate and a composite piezoelectric material coating (including a main piezoelectric ceramic and a flexible piezoelectric polymer), and realizes multiple functions through time-division multiplexing technology. This design not only improves the system integration but also reduces the complexity and cost.

The predictive maintenance module uses deep learning algorithms to identify potential faults, and the adaptive maintenance scheduling algorithm optimizes the maintenance plan to reduce downtime. The system also includes an intelligent power management module with load balancing and peak shaving functions to optimize energy utilization. The high-speed multi-channel data acquisition module continuously collects equipment operation data, and combines information such as lubricating oil consumption trends and stress distribution to comprehensively evaluate the equipment health status.

[0037] 4. Environmental adaptability and remote monitoring capabilities. The intelligent thermosensitive polymer enables the lubrication system to adapt to a wide temperature range, and the dynamically adjustable heating and anti-corrosion system enables the equipment to adapt to various working environments. 5G network support and wireless communication modules enable real-time remote monitoring and control, improving management efficiency and response speed. The system can automatically adjust according to actual environmental conditions, such as adjusting the heating strip to the optimal working temperature based on the obtained temperature, and precisely controlling the heating power through PWM technology.

The self-repairing additive can continuously repair micro-wear, significantly extending the service life of the wire rope and the entire device. The AR-functional human-machine interface not only makes equipment status monitoring more intuitive but also guides on-site personnel to perform precise maintenance operations, improving maintenance efficiency and safety. When the system is shut down, the control system gradually reduces the heating power while monitoring temperature changes and executes the flushing procedure of the lubricating oil circulation system, including using nano-composite material lubricating oil for final protection. In the standby mode, the system maintains environmental monitoring with the lowest power consumption to ensure the safety of the equipment in the non-working state while saving energy.

[0049] The following will describe three embodiments of this application in detail with reference to the accompanying drawings.

[0050] Embodiment 1

[0051] The lifting device for steel structure processing in this embodiment includes a lifting device and a control system. The core component of the lifting device is the steel wire rope 1 for lifting. The steel wire rope 1 adopts a variable cross-section design, with a larger cross-section in the middle to improve the load-bearing capacity and smaller cross-sections at both ends to increase flexibility. An outer protective layer is provided at the outer end of the steel wire rope 1. This protective layer is made of modified high-density polyethylene and added with nanoscale carbon fibers to improve wear resistance and thermal conductivity.

[0052] A lubricating oil conduit 2 is provided in the center of the steel wire rope 1. The lubricating oil conduit 2 is made of 316L stainless steel and has excellent corrosion resistance and strength. The lubricating oil conduit 2 includes an oil supply pipe 3 and a return pipe 5, which are fixedly connected through a spiral isolation layer 4. The spiral isolation layer 4 not only enhances the structural strength but also optimizes the oil flow channel.

[0053] One end of the lubricating oil conduit 2 is fixedly connected with a circulating oil pump. The oil outlet of the circulating oil pump is communicated with the oil supply pipe 3, and the return port is communicated with the return pipe 5. In order to precisely control the oil flow, flow sensors and flow control valves are provided at both the oil outlet and the return port of the circulating oil pump.

[0054] A plurality of micro-holes are provided on the oil supply pipe 3 and are spirally arranged along its axis. These micro-holes are made by laser precision machining technology, and the pore diameter varies along the length direction of the steel wire rope 1 to ensure uniform distribution of lubricating oil. In order to further optimize the oil flow, the inner walls of the oil supply pipe 3, the return pipe 5 and the outer wall are all coated with an oil-repellent nano-coating.

[0055] The outer end of the lubricating oil conduit 2 is wound with a heating strip 6. The heating strip 6 includes a nickel-chromium alloy substrate, and its outer end is coated with a piezoelectric material coating for realizing heating and monitoring functions.

[0056] The lubricating oil conduit 2 is filled with a mixed lubricating oil with a special formula. The lubricating oil is composed of a lubricating oil matrix, 80% zinc powder and 20% graphene. The lubricating oil matrix adopts nano-composite material technology to disperse nano-ceramic particles in the base oil, significantly improving the anti-wear performance. In addition, the lubricating oil matrix is also added with a smart thermosensitive polymer, which can automatically adjust the viscosity within a wide working temperature range from -40°C to +60°C. The lubricating oil also contains a self-repairing additive, which can repair the wear of the metal surface at the micro scale. In order to facilitate leakage detection and visualization analysis of the lubrication condition, a fluorescent tracer is also added to the lubricating oil matrix.

[0057] The lubricating oil of the present invention adopts a special formula and can still maintain good fluidity under extremely cold conditions from -40°C to 0°C. The smart thermosensitive polymer can adjust the viscosity of the lubricating oil in real time according to the temperature change, increasing the viscosity at -40°C to prevent leakage and decreasing the viscosity when the temperature rises to ensure sufficient lubrication. The wire rope is made of a special alloy steel with low-temperature strengthening treatment and still maintains good toughness and strength at extremely low temperatures.

[0058] The lubricating oil conduit, the oil supply pipe and the return pipe all adopt a double-layer structure design. The inner layer is 316L stainless steel, and the outer layer is wrapped with nano-aerogel thermal insulation material, effectively preventing freezing in a -40°C environment. The circulating oil pump adopts an anti-freeze motor and is equipped with a smart heating device to ensure normal startup and operation at extremely low temperatures.

[0059] The micropores are made of shape memory alloy materials and can automatically adjust the pore size in a low-temperature environment to ensure the uniform distribution of the lubricating oil. At the same time, the surface of the micropores undergoes special hydrophobic nano-treatment to prevent ice blockage.

[0060] Working process:

[0061] Before startup, the control system first checks the status of all components, including the tension of the wire rope 1, the integrity of the lubricating oil conduit 2 and the working status of the circulating oil pump.

[0062] Start the circulating oil pump, and the mixed lubricating oil begins to circulate between the oil supply pipe 3 and the return pipe 5. The flow sensor monitors the oil flow condition in real time, and the flow control valve adjusts the oil volume as needed.

[0063] Through the micropores on the oil supply pipe 3, the lubricating oil is evenly distributed to each part of the wire rope 1. The gradual change design of the pore size ensures uniform lubrication in the length direction.

[0064] The heating strip 6 starts heating according to the ambient temperature and working requirements. The intelligent thermosensitive polymer senses the temperature change and automatically adjusts the viscosity of the lubricating oil to ensure the best lubrication effect at different temperatures.

[0065] During the lifting process, the self-healing additive continuously acts on the surface of the wire rope 1 to repair micro wear. At the same time, zinc powder and graphene provide additional lubrication and anti-corrosion protection.

[0066] The control system monitors the lubrication status in real time through the fluorescent tracer. If any abnormality is found, it will adjust the lubrication parameters in time or issue an alarm.

[0067] The design of the wire rope 1 with variable cross-section improves the overall load-bearing capacity, while ensuring the flexibility at both ends, enhancing the adaptability and safety of the lifting device.

[0068] The 316L stainless steel lubricating oil conduit 2 and the modified high-density polyethylene outer protective layer greatly improve the corrosion resistance and service life of the device.

[0069] The spiral isolation layer 4 not only enhances the structural strength, but also optimizes the oil flow channel, improving the lubrication efficiency.

[0070] The microholes and gradually changing pore diameter designed by laser precision machining ensure the uniform distribution of the lubricating oil, significantly improving the lubrication effect.

[0071] The oil-repellent nano-coating reduces the friction of the pipe wall and improves the lubricating oil circulation efficiency.

[0072] The mixed lubricating oil with a special formula has excellent anti-wear, self-healing and wide temperature adaptability, greatly extending the service life of the wire rope 1.

[0073] The intelligent thermosensitive polymer enables the lubrication system to adapt to different working environments, ensuring the best lubrication effect at various temperatures.

[0074] The self-healing additive can continuously repair micro wear and prevent the occurrence of severe wear.

[0075] The addition of the fluorescent tracer makes the lubrication status visible, facilitating real-time monitoring and timely maintenance.

[0076] The overall design realizes the organic combination of multiple functions such as lubrication, anti-corrosion and monitoring, significantly improving the performance and reliability of the lifting device.
