AI Technical Summary

Technical Problem

Existing traction-type fluidized solidified soil backfilling equipment generates severe impact force and torque due to inertia when turning, which makes the connection parts easily damaged or thrown off, and lacks an effective buffer structure.

Method used

The quick-release assembly includes an extension rod, air chamber, piston plate, sliding column, spring, and rotating block. The elastic components absorb impact force, the sliding and rotating components adapt to displacement, and the air chamber inflation and locking mechanism enhances the stability and flexibility of the connection.

Benefits of technology

It effectively buffers instantaneous impact, reduces damage to connection points, prevents vehicle bodies from flying off, and improves construction safety and efficiency.
