Safety brake device for a track and a stacker

Abstract

The utility model discloses a kind of safety braking devices and stacking machines for track.The device includes mounting seat, two groups of symmetrically arranged brake assembly and pull rod mechanism.Each brake assembly contains brake block, slide bar and swing bar, constitutes parallelogram mechanism, ensure that brake block action always keep parallel posture with track.Pull rod mechanism is through rotating rod, trigger frame and pull rod, after receiving speed limiter signal, synchronously trigger two sides brake block opposite movement, clamping track two sides to realize braking.Its advantage lies in bilateral synchronous clamping, braking force is big and stable, avoids deflection and impact;Parallelogram mechanism guarantees that brake block is contacted with track comprehensively, and braking efficiency is high;Dish spring design plays the role of buffering and damping.The device can be linked in multiple groups, significantly improve the safety and reliability of stacking machine and other equipment.
