AI Technical Summary
Technical Problem
Existing tower crane boom lubrication devices suffer from uneven wire rope lubrication, leading to a high risk of detachment, and the lubricant quality testing is inconvenient, affecting operational safety and efficiency.
Method used
A lubrication mechanism including an inner brush ring, gears, a motor, a cam, and an oil injector was designed. The motor controls the rotation of the cam to drive the piston to move, thereby achieving uniform spraying of lubricating oil and convenient detection by the detection components, ensuring the quality of the lubricating oil.
Benefits of technology
It improves the uniformity of wire rope lubrication, reduces the risk of pull-out, and enhances the convenience of lubricant testing and the safety of use.
