AI Technical Summary
There is a gap at the hinge joint between the top beam and the shield beam of the hydraulic support, which makes it easy for coal and gangue to fall into the support, endangering personnel safety and damaging electrical control components.
A filler and a limiting element are installed at the hinge of the hydraulic support. The filler undergoes elastic deformation when the two beams rotate relative to each other to fill the space without gaps. The limiting element is located at the top and bottom of the space to limit the filler and prevent it from falling out.
It effectively prevents debris from entering the support, protecting the safety of the underlying mechanism and personnel, while allowing the beam to rotate smoothly and avoid damage. It is suitable for all types of hydraulic supports.
