The hook is mainly composed of a hook body, a hook rod, a hook seat, a lifting ring, a thrust bearing and a spring. The requirements for the big hook for drilling rig operations are: it should have sufficient strength and working reliability; the hook body can be flexibly rotated to facilitate buckling and unbuckling; the stroke of the hook spring should be sufficient to compensate for the distance between the upper and unloading drill rods; The locking device of the hook mouth and the side hook should be absolutely reliable and easy to close and open; the big hook should have a buffer and shock absorption function to reduce the impact of disassembling the standing root.
