In steam, the specific working mode of the locking member 533 is that the rotating locking hook 54 is hinged to the mounting hole 534, so that the rotating locking hook 54 can rotate in a vertical plane, when the auxiliary hanging member 532 is connected to the drill rod, a worker inserts one end of the auxiliary hanging member 532, which is far away from the drill rod, into the secondary section 53 and continuously extends into the secondary section 53, and since the outer wall of the auxiliary hanging member 532 has a limiting effect on the rotating locking hook 54, the rotating locking hook 54 is always in an unfolded state; when the clamping ring groove 5321 of the auxiliary hanging piece 532 moves to the position of the first-stage step 541, the first-stage step 541 can freely rotate in the clamping ring groove 5321, a worker needs to slowly close the rotary locking hook 54 and enable the first-stage step 541 to be located in the clamping ring groove 5321, then a drill rod is released, and the clamping ring groove 5321 drives the first-stage step 541 to rotate and enables the rotary locking hook 54 to integrally rotate when the drill rod falls due to gravity. When the rotary lock hook 54 rotates to a completely closed state, the third-stage step 543 abuts against the outer side surface of the second-stage section 53, the second-stage step 542 abuts against the outer side surface of the auxiliary hanging piece 532, so that the first-stage step 541 stops rotating, the drill rod stops falling, position fixing in the elevator main body 51 is achieved, and after fixing, the positioning pin 545 is inserted into the positioning hole to improve the connection stability between the auxiliary hanging piece 532 and the elevator main body 51.
When the drill rod and the elevator main body 51 need to be separated, a worker can lift the drill rod or fix the lower end of the drill rod and move the elevator main body 51 downwards, namely, the elevator main body 51 and the auxiliary hanging piece 532 slide relatively, the lower end of the first-stage step 541 rotates under the limiting action of the clamping ring groove 5321, so that the closed rotary locking hook 54 is gradually unfolded, when the rotary locking hook 54 rotates to a completely unfolded position, the rotary locking hook 54 and the auxiliary hanging piece 532 are completely separated, the worker needs to press the end of the rotary locking hook 54 to enable the rotary locking hook 54 and the auxiliary hanging piece 532 to be kept in a completely separated state, and the drill rod and the elevator main body 51 can be quickly separated.
The hard spring 564 is arranged to buffer the axial impact force generated by the elevator body 51 during use, so as to reduce the excessive acting force generated by the axial impact force on the first stage 52, protect the first stage 52, and reduce the occurrence of fracture of the first stage 52.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
