The invention relates to the technical field of lifting hooks, and particularly relates to a self-locking lifting hook for lifting equipment. The self-locking lifting hook comprises a connecting sleeve, a detection device, a protection device and a self-locking device, wherein the detection device is arranged at the top end of the inner side of the connecting sleeve and penetrates through the connecting sleeve; a lifting ring is arranged at the top end of the detection device and fixedly connected with the detection device; a hook body is arranged at the bottom end of the inner side of the connecting sleeve and rotationally connected with the connecting sleeve; and the protection device is arranged at the bottom end of the outer side of the hook body. According to the self-locking liftinghook, a protection layer is arranged and matched with sliding connection of the protection layer and the hook body, sliding connection of the protection layer and a front limiting frame as well as a rear limiting frame and spiral connection of a screw and the front limiting frame; when the device is used, the protection layer made of a tungsten carbide material is arranged at the bottom end of theouter side of the hook body, so that the phenomenon of abrasion of a contact part of the lifting hook and an object can be avoided to the greatest extent, the service life of the device is prolonged,and the phenomenon of unhooking of the object due to deformation of the lifting hook is avoided.

    本发明涉及吊钩技术领域,尤其为一种吊装设备用自锁吊钩,包括连接套、检测装置、防护装置和自锁装置,所述连接套内侧顶端设有检测装置,且检测装置贯穿连接套,所述检测装置顶端设有吊环,且吊环与检测装置固定连接,所述连接套内侧底端设有钩体,且钩体与连接套转动连接,所述钩体外侧底端设有防护装置,本发明中,通过设置的防护层,这种设置配合防护层与钩体的滑动连接、防护层与前限位架及后限位架的滑动连接和螺钉与前限位架的螺旋连接,在使用装置时,通过在钩体外侧底端设置碳化钨材质的防护层,可以最大程度的避免吊钩与物体接触部分出现磨损的现象,延长了装置的使用寿命,避免了吊钩出现变形导致的物品脱钩的现象。
