The invention provides an anti-locking ratchet wheel self-locking mechanism which comprises a ratchet wheel (100), a pawl (200), a connecting rod (300), a traction electromagnet (400) and a state detection switch (500). The traction electromagnet (400) can drive the pawl (200) to move towards two sides and realize separation and locking of the pawl (200) and the ratchet wheel (100), the connectingrod (300) is made of non-magnetic metal materials, a pawl round head (210) is arranged in an arc shape, a controller module (420) is installed in the traction electromagnet (400), and the traction electromagnet (400) adopts direct current and other measures, so that the pawl (200) and the ratchet wheel (100) are effectively prevented from being locked, operation efficiency is improved, productioncost is reduced, maintenance cost is reduced, and unsafe factors caused by maintenance are reduced.

    本发明提供了一种防锁死的棘轮自锁机构,包括棘轮(100)、棘爪(200)、连接杆(300)、牵引电磁铁(400)以及状态检测开关(500),牵引电磁铁(400)能驱使棘爪(200)向两侧移动并实现棘爪(200)与棘轮(100)分离和锁住,其中,通过连接杆(300)采用无磁金属材料、棘爪圆头(210)设置为圆弧状、牵引电磁铁(400)内安装控制器模块(420)、牵引电磁铁(400)采用直流电等措施,有效防止棘爪(200)和棘轮(100)锁死,提高了作业效率,降低了生产成本,同时也降低了维修成本,减少了因维修带来的不安全因素。
