Description
Technical field
The utility model belongs to rig field of tool in engineering machinery, relates to a kind of device of landing drilling tool in drilling machine construction process, is specifically related to a kind of hook-type elevator.
Background technology
Elevator is in drilling machine construction process, is used for carrying a kind of instrument hanging drilling tool time lifting drilling tool (mainly drilling rod).By the difference of extracting mode, elevator is divided into sliding ring type elevator, hand-scrubbing type elevator and tiltedly takes off formula elevator etc.Wherein with the manual dislodging elevator technology relative maturity that sliding ring type elevator is representative, but carry and draw in drilling tool process, need workman to set out when being separated with drilling tool, inevitably need operation on workman's tower.Tiltedly de-formula elevator can realize tower departs from drilling tool automatically, but easily landing occurs when drilling tool is not suspended to, and during lifting water tap, existence and the fire hose crown hang the risk automatically disengaged.
Summary of the invention
The purpose of this utility model is to provide one and automatically can be separated with drilling tool on tower, prevents the fire hose crown from hanging the hook-type elevator come off.
The utility model comprises drop handle, elevator main body, hook, spring, thrust ball bearing and garter spring, elevator body top is divided into solid post, bottom is divided into cylinder, cylinder top is provided with upper flange, uniform four square openings in cylinder bottom, set flange below square opening, each square opening both sides are all welded with floor; Hook is three grades of stairsteppings, to be embedded in square opening and to be supported by lower flange, hook and floor by pinned connection and can around bearing pin ° within the scope of rotate, the cavity that hook could stretch into and stretch out elevator main body realizes that card is got, unfreezing drilling tool; Garter spring is arranged on upper flange by screw thread, and garter spring can turn in the axial direction, the path that when garter spring is in lower limit position, hook capable of blocking rotates around bearing pin, the duty of lockable hook; Drop handle bottom is welded with coupling sleeve, and coupling sleeve is enclosed within solid post; Thrust ball bearing, spring, thick washer to be sleeved on successively in solid post and to be seated on the interior step of coupling sleeve, thrust ball bearing, spring and thick washer to be tightened be fixed on solid post by packing ring and nut; Time unloaded, initial tension of spring is greater than elevator self gravitation, and carry spring when drawing drilling tool and compressed, thick washer is seated on the step of the coupling sleeve second level, by the spring that compresses can drilling tool upwards play time promote elevator main body and hook is up, prevent unexpected unfreezing.
When the utility model uses, tool joint is connected to after on drilling rod, start to carry and draw work, first, turn-knob garter spring is up, abdicates the rotating channel of hook, tool joint is made to stretch into cavity, the simultaneously Rotary hanging hook of elevator main body, make hook snap in the annular groove of tool joint, so far, elevator achieves card and gets drilling tool; Then, operation hoist engine promotes drop handle, and spring is compressed, and thick washer 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 be carried smoothly to be drawn; Finally, carry after drawing drilling tool to precalculated position, fix drilling tool, operation hoist engine makes elevator lean on gravity descending, thick washer is separated with coupling sleeve second level step, spring recovers former length, and continue descending then tool joint and promote hook rotation, hook blocks annular groove, operation hoist engine makes the up and drilling rod connecting of elevator, depart from, so far, elevator achieves and being automatically separated of tool joint.
Carrying in the embodiment hanging fire hose crown extension, first, turn-knob garter spring is up, abdicate the rotating channel of hook, make the fire hose crown hang the cavity stretching into elevator main body, simultaneously Rotary hanging hook, make 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, the operating position of locking hook, and operation hoist engine loosens wire rope, and so far, elevator achieves carries extension water tap.
Compared with prior art, the beneficial effects of the utility model are: elevator automatically can be separated with drilling tool on tower, and can prevent the fire hose crown from hanging accidental, reduce workload and the potential safety hazard of work high above the ground.
