AI Technical Summary
Existing pulley assemblies in winches only provide shock absorption in one direction, which cannot achieve comprehensive cushioning and leads to a reduced service life.
A pulley assembly with a buffer structure was designed, which adopts a structure of horizontal plate, connecting plate, buffer box, shock absorber spring and wedge block to achieve multi-directional buffering in the vertical and horizontal directions. Resonance is suppressed by the first and second shock absorber springs and dampers to enhance stability.
Multi-directional buffering of the pulley assembly is achieved, which improves stability and service life, avoids resonance damage, and extends the service life of the pulley assembly.
