Description

Technical Field

[0001] This invention relates to the field of lubrication technology for steel rolling equipment, and more particularly to a lubrication monitoring system for the wheel axle support of a double-sided shear main reducer. Background Technology

[0002] Double-sided shears are the main edge-cutting equipment in medium-thick and wide-thick plate production lines. They are driven by two main reducers, one on each side. Each main reducer has three output crankshafts connected to the upper blade holder. Shearing subjectes the blade holder to extremely high radial loads and frequent impact loads. These loads are borne by the output crankshafts of the main reducers. Current technology uses rolling bearings to support the output crankshafts, but rolling bearings have a high failure rate under frequent radial impact loads and are expensive to manufacture. Furthermore, rolling bearings occupy a large space, making the design space of the shear machine itself quite limited. With the development of intelligent manufacturing, smart workshops require real-time monitoring of the operating status of the double-sided shear's main reducers throughout the entire process. However, current technology lacks the ability to monitor the operating status of the wheel and axle support structure in real time. Any unexpected bearing failure can cause sudden production line shutdowns, resulting in significant economic losses.

[0003] To address the aforementioned issues, there is an urgent need to develop a structure and device that can better withstand frequent radial impact loads, make the space more compact, reduce manufacturing costs, and simultaneously monitor the operating status of the wheel axle support structure in real time. Summary of the Invention

This system, through its wheel axle support structure, wheel axle lubrication structure, and condition monitoring device, enables the double-sided scissor main reducer to better withstand frequent radial impact loads, while also making the space more compact and reducing manufacturing costs. Simultaneously, it allows for real-time monitoring of the operating status of the wheel axle support structure, meeting the needs of intelligent manufacturing.

[0005] The technical means employed in this invention are as follows:

[0012] Furthermore, the split structure of the first sliding sleeve includes a first upper sliding sleeve and a first lower sliding sleeve, and the split structure of the third sliding sleeve includes a third upper sliding sleeve and a third lower sliding sleeve; the first sliding sleeve is provided with four sets of screws and a first pin hole at both ends.

[0013] Furthermore, the first upper circumferential lubrication groove and the first lower circumferential lubrication groove in the wheel axle lubrication structure are connected to the first internal lubrication groove, and the end faces of the first sliding sleeve, the third sliding sleeve and the sixth sliding sleeve are all provided with end face lubrication grooves, and a plurality of lubrication holes are distributed in the internal lubrication groove.

[0014] Furthermore, the condition monitoring device includes: a high-speed shaft temperature monitoring device and a high-speed shaft vibration monitoring device installed on each of the two high-speed shafts;

[0015] A second output crankshaft temperature monitoring device is installed on the first sliding sleeve of the first shear output crankshaft and the fourth sliding sleeve of the second shear output crankshaft.

[0016] A first output crankshaft temperature monitoring device is installed on the third sliding sleeve of the first shear output crankshaft, the third sliding sleeve of the second shear output crankshaft, and the sixth sliding sleeve of the fragment shear output crankshaft.

[0017] Furthermore, the third sliding sleeve is fixed to the upper body via an upper keyway, and the sixth sliding sleeve is fixed to the lower body via a lower keyway.

[0018] Furthermore, all sliding sleeves are equipped with lubrication monitoring devices to monitor the lubrication status of the wheel axle support structure in real time.

[0019] Furthermore, the sixth sliding sleeve of the broken shear output crankshaft is an integral structure, and its lubrication structure consists of a first upper circumferential lubrication groove and a first lower circumferential lubrication groove, which are continuous integral lubrication grooves.

[0020] Furthermore, the cables of the high-speed shaft temperature monitoring device and the high-speed shaft vibration monitoring device are led out to the outside through conversion connectors to collect operating data in real time.

[0021] By adopting the above technical solution, the present invention has the following advantages compared with the prior art:

[0022] 1. The present invention provides a lubrication monitoring system for the wheel axle support of a double-sided scissor main reducer. In view of the problem that the failure rate of rolling bearings under frequent radial impact loads is high, this application improves the ability of the double-sided scissor main reducer to resist frequent impact loads by designing a new wheel axle support structure, eliminating the rolling bearing and replacing it with a sliding sleeve structure that is more adaptable to radial impact loads under low speed conditions.

[0023] 2. The present invention provides a lubrication monitoring system for the wheel axle support of a double-sided scissor main reducer. In view of the problem of high manufacturing cost of the output crankshaft support structure of the double-sided scissor main reducer, this application reduces the manufacturing cost by designing a new wheel axle support structure, eliminating the rolling bearing and replacing it with a sliding sleeve structure with lower manufacturing cost.

[0024] 3. The present invention provides a lubrication monitoring system for the wheel axle support of a double-sided scissor main reducer. In view of the problem that rolling bearings occupy a large amount of space, this application designs a new wheel axle support structure, eliminates rolling bearings and replaces them with a more compact sliding sleeve structure, thereby reducing the space occupied and improving the design space of the main load-bearing structure of the double-sided scissor main reducer, and further improving the reliability of the double-sided scissor main reducer.

[0025] 4. The present invention provides a lubrication monitoring system for the wheel axle support of a double-sided scissor main reducer. In response to the need for real-time monitoring of the operating status of the double-sided scissor main reducer throughout the entire cycle in a smart workshop, this application realizes real-time monitoring of the temperature, vibration and lubrication status of each support component in the wheel axle support structure throughout the entire cycle through the set status monitoring device, so as to avoid economic losses caused by sudden damage leading to production stoppage.

[0026] 5. The present invention provides a wheel axle support lubrication monitoring system for a double-sided shear reducer, which is equipped with a wheel axle lubrication structure, which can fully lubricate the sliding sleeve. The pressurized oil can separate the inner wall of the sliding sleeve from the output crankshaft, thereby better reducing the temperature of the sliding sleeve and providing lubrication. It can better adapt to the operation of the sliding sleeve under low speed, heavy load and frequent radial load impact conditions.

[0027] Based on the above reasons, this invention can be widely promoted in the field of lubrication technology for steel rolling equipment. Attached Figure Description

[0054] Furthermore, the split structure of the first sliding sleeve 3 and the third sliding sleeve 5 includes the first upper sliding sleeve 3-1 and the first lower sliding sleeve 3-2, the third upper sliding sleeve 5-1 and the third lower sliding sleeve 5-2, and each end is provided with four sets of screws and the first pin hole 3-9. The split structure is fixed by screws and pin holes, which enhances the connection strength between the sliding sleeve and the machine body and prevents loosening. At the same time, the split design facilitates disassembly and replacement, reducing maintenance difficulty and time cost.

[0055] Furthermore, the first upper circumferential lubrication groove 3-6 and the first lower circumferential lubrication groove 3-7 in the wheel axle lubrication structure are connected to the first internal lubrication groove 3-4, and the end faces of the first sliding sleeve 3, the third sliding sleeve 5 and the sixth sliding sleeve 8 are all provided with end face lubrication grooves. Several lubrication holes are distributed in the internal lubrication grooves, which can enable lubricating oil to quickly penetrate to the friction surface through the connecting grooves, reduce the risk of local dry friction, optimize the flow path of lubricating oil, and effectively reduce the working temperature of the sliding sleeve.

[0056] Furthermore, the condition monitoring device includes: a high-speed shaft temperature monitoring device 11 and a high-speed shaft vibration monitoring device 12 installed on each of the two high-speed shafts 17;

[0057] A second output crankshaft temperature monitoring device 14 is provided on the first sliding sleeve 3 of the first cutting shear output crankshaft 1-1 and the second cutting shear output crankshaft 1-2 and the fourth sliding sleeve 6 of the fragmentation shear output crankshaft 2.

[0058] A first output crankshaft temperature monitoring device 13 is installed on the third sliding sleeve 5 of the first cutting edge shear output crankshaft 1-1 and the second cutting edge shear output crankshaft 1-2 and the sixth sliding sleeve 8 of the fragmentation shear output crankshaft 2.

[0059] Sensors are deployed at key locations on the high-speed shaft 17 and different output crankshafts to ensure no monitoring blind spots. Two types of temperature sensors are set up to adapt to the monitoring needs of different load areas and improve data reliability.

[0060] Furthermore, the third sliding sleeve 5 is fixed to the upper body via the upper keyway 5-3, and the sixth sliding sleeve 8 is fixed to the lower body via the lower keyway 8-1. The keyway and the flat key cooperate to prevent the sliding sleeve from rotating relative to the body, thereby enhancing structural stability. The key connection ensures that the sliding sleeve is installed in a precise position and reduces assembly errors.

[0061] Furthermore, all sliding sleeves are equipped with lubrication monitoring devices 16 to monitor the lubrication status of the wheel axle support structure in real time. The lubrication monitoring devices 16 can monitor parameters such as oil pressure and oil quantity of each sliding sleeve in real time to prevent abnormal wear caused by insufficient lubrication.

[0062] Furthermore, the sixth sliding sleeve 8 of the broken shear output crankshaft 2 is an integral structure. In its lubrication structure, the first upper circumferential lubrication groove 3-6 and the first lower circumferential lubrication groove 3-7 are continuous integral lubrication grooves. The continuous groove design ensures that the lubricating oil flows without interruption in the integral sliding sleeve, avoiding local oil film rupture. The integral structure simplifies the processing technology and improves the matching accuracy with a specific crankshaft.

[0063] Furthermore, the cables of the high-speed shaft temperature monitoring device 11 and the high-speed shaft vibration monitoring device 12 are led out to the outside through the conversion connector 15 to collect operating data in real time. The conversion connector 15 reduces cable interference and ensures high-fidelity transmission of monitoring data. The modular interface design facilitates sensor replacement or upgrade and reduces maintenance complexity.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention 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 or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
