The invention discloses a container lifting oil cylinder fracture safety protection device and a mining dump truck. The container lifting oil cylinder fracture safety protection device comprises a bottom plate, a rotating component and a locking component, wherein the rotating component is mounted on the bottom plate and has an automatic reset function; the locking component is mounted on the bottom plate; the locking and unlocking states between the rotating component and the locking component are achieved through the ratchet wheel and pawl assembly. When the signal rope is not broken, the pawl is separated from the ratchet wheel, the ratchet wheel can normally rotate, the torsion springs are arranged on the left and right sides of the ratchet wheel respectively, the working steel wire rope wound on the ratchet wheel can freely stretch out and draw back, the length of the working steel wire rope is adjustable, and the container lifting function is not affected. When the signal rope is broken, the pawl falls under the action of gravity and the tension spring, the pawl rapidly makes contact with the ratchet wheel, the ratchet wheel cannot rotate, the wound working steel wire rope cannot stretch out, the container is fixed to the current position and cannot fall, and the safety protection effect is achieved.
本发明公开了一种货箱举升油缸断裂安全防护装置及矿用自卸车,包括底板、安装在底板上且具有自动复位功能的旋转部件和安装在底板上的锁止部件;旋转部件与锁止部件之间的锁止与解锁状态通过棘轮棘爪组件进行实现;当信号绳未断裂时,棘爪脱离棘轮,棘轮可以正常旋转,棘轮左右各装一个扭簧,此时缠绕在棘轮上的工作钢丝绳可以自由伸缩,工作钢丝绳长度可调,不影响货箱举升功能;当信号绳断裂时,棘爪在重力、拉簧的作用下下落,棘爪快速与棘轮接触,棘轮无法旋转,缠绕的工作钢丝绳无法伸出,货箱固定到当前位置,无法下落,起到安全防护作用。
