Abstract

The utility model discloses a symmetrical bidirectional lifting hook for oil derrick hoisting. A forged flat steel billet is adopted; the upper part of the forged flat steel billet is processed into a cylinder with a bolt head, and the lower part of the forged flat steel billet is processed into circular arc; two sides of the forged flat steel billet are symmetrically provided with inclined bidirectional notches provided with elastic anti-loosing devices at upper sides; a lifting hook seat is a hollow sunk cylinder of which the upper part is provided with an external thread; a baseboard is drilled with a hole; a circular arc board with holes is arranged above a lifting eye, and a hollow cylinder with a tapped blind hole is arranged below the lifting eye; the cylinder of the lifting hook, which is provided with the bolt head, passes through a cylinder hole on the baseboard of the lifting hook seat and is connected with a thrust bearing, a thickening nut and an anti-loosing screw in the lifting hook seat; and after the cylinder with the external thread above the lifting hook seat is connected with the tapped blind hole below the lifting eye, the cylinder with the external thread is fixed from the side surface by a set screw. The favorable centring performance of the lifting hook can be guaranteed no matter when the lifting hook for hoisting is respectively hooked with two slings and when one sling is simultaneously hooked on two notches, the lifting hook has small possibility of inclining and slipping and can rotate flexibly, and thus hoisting quality and labor productivity can be simultaneously improved.

Description

A kind of derrick rises reuses the two-way suspension hook of symmetrical expression
Technical field
The utility model relates to petroleum machinery, the improvement design of derrick lifting gear " suspension hook ".
Background technology
In the petroleum drilling and mining process, using derrick to lift by crane various utensils is a very frequent job.And in crane lifting service, the performance of suspension hook will directly have influence on the efficient of drilling work and play the safety of heavy mail.At present, during the derrick lifting of oil field, what use in a large number is unidirectional suspension hook.Unidirectional suspension hook has only a breach that articulates hoist cable, if hoist cable is thicker, and two stacking pattern one on the other appears in regular meeting, causes the hoist cable both sides different in size when using simultaneously, the balance of influence lifting article.In addition, unidirectional suspension hook banking is easy to, slippage when heavy duty, and the lifting accident takes place.So, load hook is improved raising, necessary.
Summary of the invention
The purpose of this utility model be to design a kind of not only suitable two hoist cables, but also a suitable hoist cable lifting use, balance is good, intensity improves, rotate flexibly, the two-way suspension hook of not eely a kind of symmetrical expression.
The utility model is made up of the gauge member of suspension hook, elasticity anti-dropping device, suspension hook seat, hanger and rotation, connection, its unique distinction is: suspension hook adopts the flat steel billet that forges, the cylinder of strap bolt head is processed in the top, circular arc is processed in bottom, have to bilateral symmetry the two-way breach of bevelled, the elasticity anti-dropping device all is housed in the top of two-way breach; The suspension hook seat is that externally threaded depression hollow cylinder is with in the top, is drilled with a cylindrical hole on the base plate, thrust baring is arranged in the body, add high nut and anti-avulsion screw; The hanger top is arc plate with holes, the hollow cylinder that the below is threaded blind hole; The cylinder of suspension hook top strap bolt head passes the cylindrical hole on the suspension hook seat base plate, with thrust baring in the suspension hook seat, add high nut and the anti-avulsion screw links; After suspension hook seat top is with externally threaded cylinder and hanger below threaded blind hole is connected, fixing from the side with holding screw again.
Because suspension hook of the present utility model has the two-way breach of bevelled symmetrically, no matter is to articulate hoist cable respectively from both sides, still a hoist cable is articulated on two breach simultaneously, can both guarantee the centering performance that it is good, and be difficult for tilting and slippage.Suspension hook can rotate flexibly with respect to suspension hook seat and hanger, makes suspension hook very to turn to easily with hoist cable and articulates, thereby further improve lifting quality and labor efficiency.
Description of drawings
Accompanying drawing is an overall structure half section scheme drawing of the present utility model.
Parts title in the accompanying drawing shown in the label is as follows:
1, suspension hook, 2, the elasticity anti-dropping device, 3, the suspension hook seat, 4, hanger, 5, add high nut, 6, the anti-avulsion screw, 7, holding screw, 8, thrust baring, 9, straight pin, 10, torsion spring, 11, anti-tripping.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
The utility model is formed a complete parts product by the gauge member of suspension hook, elasticity anti-dropping device, suspension hook seat, hanger and rotation, connection.Suspension hook (1) adopts the flat steel billet that forges, and the cylinder of strap bolt head is processed in the top, and circular arc is processed in bottom, has to bilateral symmetry the two-way breach of bevelled, in the top of two-way breach elasticity anti-dropping device (2) is housed all.Elasticity anti-dropping device (2) is made up of the groove of straight pin (9), torsion spring (10), anti-tripping (11) and suspension hook (1) breach top, and straight pin (9) is locked in centre hole and anti-tripping (11) porose end of torsion spring (10) in the circular hole of groove upper end; One end of anti-tripping (11) atresia under the effect of hoist cable and torsion spring (10) power, can swing back and forth in the breach of suspension hook (1); After hoist cable entered breach, elasticity anti-dropping device (2) can be sealed breach automatically, to prevent the hoist cable slippage.Suspension hook seat (3) is that externally threaded depression hollow cylinder is with in the top, is drilled with a cylindrical hole on the base plate, is used to articulate suspension hook (1).Hanger (4) top is an arc plate with holes, uses with derrick to be connected; The below is the hollow cylinder of threaded blind hole, uses with suspension hook seat (3) to connect.
During assembling, the cylinder of suspension hook (1) top strap bolt head passes the cylindrical hole on suspension hook seat (3) base plate, with thrust baring (8) in the suspension hook seat (3), add high nut (5) and anti-avulsion screw (6) links; Suspension hook (1) can rotate flexibly with respect to suspension hook seat (3) and hanger (4), it can very be turned to hoist cable easily be connected.After suspension hook seat (3) top is with externally threaded cylinder and hanger (4) below threaded blind hole is connected, use holding screw (7) to fix from the side again, prevent the thread looseness that connects and come off.
All outer corners of suspension hook of the present utility model (1), elasticity anti-dropping device (2), suspension hook seat (3) and hanger (4), whole chamferings or rounding are with wearing and tearing that reduce hoist cable and the safety that guarantees operating personal.
