AI Technical Summary
Existing construction hoists lack effective anti-collision devices or rely solely on simple anti-collision plates, resulting in poor anti-collision performance and a low safety factor.
An anti-collision safety device was designed, comprising a crash plate, a spring, a top column, a crash strip, and a support mechanism. The impact force is reduced by the energy absorption effect of the crash plate, the top column, and the crash strip. The spring is used for reset, and the device is guided by the limiting groove and the limiting block. The support rod reduces the noise when the door closes.
It effectively reduces the impact force when the lifting door is hit, improves safety, reduces closing noise, and enhances the protective performance of the lifting platform.
