On interior step, by packing ring and nut, thrust ball bearing, spring and thick washer are tightened and be fixed on solid post;When unloaded, spring is pre-
Clamp force is more than elevator self gravitation, carries spring when drawing drilling tool and is compressed, thick washer is seated on the step of the coupling sleeve second level, is pressed
The spring of contracting can promote elevator main body and hook up in drilling tool play upwards, prevents unexpected unfreezing.
When the present invention uses, after tool joint is connected on drilling rod, starts to carry and draw work, first, turn-knob garter spring is up,
Concede the rotating channel of hook, make tool joint stretch into the cavity of elevator main body, Rotary hanging hook simultaneously, make hook snap in drilling rod
The annular groove of joint, so far, elevator achieves card and takes drilling tool;Then, operation hoist engine lifting drop handle, spring is compressed, hassock
Circle is seated on the step of the coupling sleeve second level, and so far, the load that elevator is subject to is delivered to coupling sleeve by thick washer, and drilling rod can quilt
Smoothly carry and drawing;Finally, carry and draw drilling tool to precalculated position, fix drilling tool, operation hoist engine makes elevator lean on gravity descending, thick
Packing ring is separated with coupling sleeve second level step, and spring recovers former length, continues traveling downwardly then tool joint and promotes hook rotation, hook card
Go out annular groove, operation hoist engine makes elevator up and drilling rod connecting, departs from, so far, elevator achieves automatic with tool joint
Separate.
Hang in the embodiment that the fire hose crown hangs carrying, first, turn-knob garter spring is up, concedes the rotating channel of hook, order
The fire hose crown hangs the cavity stretching into elevator main body, Rotary hanging hook simultaneously, makes hook snap in the annular groove of fire hose crown extension, so far,
Elevator achieves card water intaking tap top and hangs;Then, knob garter spring comes downwards to lower limit position, locks the operating position of hook,
Operation hoist engine loosens steel wire rope, and so far, elevator achieves and carries extension faucet.
Compared with prior art, the invention has the beneficial effects as follows:Elevator can be automatically separated with drilling tool on tower, and can
To prevent water tap top from hanging unexpected workload and the potential safety hazard coming off, reducing work high above the ground.
