AI Technical Summary
When the turning radius of mountain roads is small, the car crane cannot enter the box-changing installation station, resulting in the box-changing transport truck being unable to rely on the car crane to unload the truck, which makes the box-changing easily structural deformation and damage during the hydraulic push-up and translation process.
A box-changing hydraulic push-translation unloading protection device is designed, including a support frame and several support brackets. The support frame is installed at the bottom of the box-changing, and the support bracket is arranged around the support frame. The hydraulic jack acts on the support bracket to disperse the acting force and reduce structural deformation.
By dispersing the force, the deformation and damage of the box change structure during the top pushing and translation process is reduced, and the box change is horizontally limited by the support support to avoid horizontal movement of the box change during the top pushing and translation process.
