After adopting such structure, the left and right clamping plates are connected with the bolt and the nut to form a structure similar to scissors. When the through holes above the left clamping plate and the right clamping plate of the drill hoisting device penetrate through the steel wire rope and are hoisted upwards, the force of inward clamping is exerted between the left arc-shaped clamping plate and the right arc-shaped clamping plate at the lower parts of the left clamping plate and the right clamping plate. The left clamping plate and the right clamping plate of the hoisting device are aligned to the joint part of the drill bit, and the drill bit body is placed upwards, so that when the drill bit joint is clamped by the left clamping plate and the right clamping plate, the diameter of the drill bit body is larger than that of the drill bit joint, and when the drill bit hoisting device is lifted, the drill bit body can be firmly located between the left clamping plate and the right clamping plate under the action of the gravity of the drill bit. In other words, the drill lifting device has the advantages of simple structure, high clamping efficiency and high safety by means of the gravity action and the special scissor type clamping principle, and the efficient drill clamping efficiency is not directly related to the proficiency of workers, so that the drill lifting device can also have high lifting efficiency and high safety coefficient by adopting a conventional lifting method. Compared with the method adopting a full-intelligent hoisting device, the method can save the drilling cost and has low operation requirement on workers.

Example two:

referring to the attached drawings 1 to 3 in the specification, the drill bit hoisting device mainly comprises a clamping plate 1, an arc-shaped clamping plate 2, a bolt 3, a nut 4, a penetrating hole 5, a matching hole 6, a matching groove 7 and a rib plate 8, wherein the clamping plate 1, the rib plate 8 and the arc-shaped clamping plate 2 are fixedly connected together, and the arc-shaped clamping plate 2 is fixed at the bottom of the clamping plate 1.
