Abstract

The invention discloses a hook-type elevator which comprises an elevator main body, hooks, a lifting ring and a hoop, wherein the upper part of the elevator main body is provided with a solid column, and the lower part of the elevator main body is provided with a cylinder; an upper flange is arranged at the upper part of the cylinder, four square holes are uniformly distributed in the lower part of the cylinder, a lower flange is arranged below the square holes, and rib plates are welded on both sides of each square hole; the hooks are embedded in the square holes and are mounted on the rib plates through hinge pins, and a dill can be clamped and released by rotating the hooks; a connection sleeve is welded at the lower end of the lifting ring, and the solid column is arranged on the connection sleeve in a sleeving manner; the solid column is sleeved by a thrust ball bearing, a spring and a thick gasket in sequence, and the thrust ball bearing, the spring and the thick gasket are fixed by tightening the gasket and a nut; and the hoop is in threaded connection with the upper flange, and the working state that a drilling tool is clamped by the hooks can be locked so long as the hoop is screwed to a lower extreme position. The hook-type elevator can be automatically separated from the drilling tool on a tower when being used for lifting the drilling tool, and can prevent accidental falling of a faucet top hanger to reduce aloft work load and potential safety hazards.

Description

Hook-type elevator

Technical field

The invention belongs to rig field of tool in engineering machinery, it is related to a kind of dress of landing drilling tool during drilling machine construction Put and in particular to a kind of hook-type elevator.

Background technology

During elevator is drilling machine construction, lifting drilling tool（Mainly drilling rod）When be used for carry hang drilling tool a kind of instrument. 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 cunning Ring type elevator is the manual dislodging elevator technology relative maturity of representative, but during carrying and drawing drilling tool, needs when separating with drilling tool Want workman to set out, inevitably need operation on workman's tower.Tiltedly take off formula elevator can realize automatically departing from drilling tool on tower, But easily there is landing when drilling tool is not suspended to, and during lifting faucet, exist and hang, with the fire hose crown, the risk automatically disengaging.

Content of the invention

It is an object of the invention to provide one kind can be automatically separated with drilling tool on tower, prevent the hook that fire hose crown extension comes off Formula elevator.

The present invention includes drop handle, elevator main body, hook, spring, thrust ball bearing and garter spring, and elevator body top divides For solid post, bottom is divided into cylinder, and cylinder top is provided with upper flange, uniform four square openings in cylinder bottom, set below square opening Lower flange, each square opening both sides are all welded with floor；Link up with as three-level stairstepping, be embedded in square in the hole and supported by lower flange, hang Hook be connected by bearing pin with floor and can around bearing pin ° in the range of rotate, hook can stretch into and stretch out the cavity of elevator main body Realize card take, unfreezing drilling tool；Garter spring by being threadably mounted on upper flange, garter spring can turn in the axial direction, garter spring is in The path that hook rotates, the working condition of lockable hook can be blocked around bearing pin during lower limit position；Drop handle bottom is welded with connection Set, coupling sleeve is enclosed within solid post；Thrust ball bearing, spring, thick washer are sleeved on successively in solid post and are seated at coupling sleeve 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.
