Abstract
The utility model discloses a safety lock type K-shaped derrick lifting hook. The safety lock type K-shaped derrick lifting hook is provided with an 8-shaped steel wire rope, a safety lock and a safety lifting hook, wherein the upper part of the 8-shaped steel wire rope is connected with a small ring and the lower part of the 8-shaped steel wire rope is connected with a big ring; one end of the safety lock is connected with a lock head, the other end of the safety lock is connected with a lock plug, a lock hole is formed in one side of the lock head, an unlocking hole is formed in the top end of the lock head and a key is arranged on the top end of the lock head; an oblate lifting hole is formed in the upper part of the safety lifting hook, the lower part of the safety lifting hook is provided with a hook, a big safety hole is formed in one side of the hook, and a small safety hole is formed in the other side of the hook; the big ring at the lower part of the 8-shaped steel wire rope passes through the oblate lifting hole in the upper part of the safety lifting hook, the small ring passes through the big ring and then is pulled straight; when the safety lock type K-shaped derrick lifting hook is in use, the safety lock is installed in the big safety hole and the small safety hole, and the lock plug is inserted into the lock hole; when the K-shaped derrick lifting hook is opened, the key hole is rotated by the key, and the lock plug automatically deviates from the lock hole. According to the technology, the safety lock type K-shaped derrick lifting hook is convenient to install and high in safety factor, unlocking does not occur, and neither fiber breakage nor deformation of the steel wire rope is caused.
Description
Technical field
The present invention relates to mechanical manufacturing field, the safe locking-type K type derrick suspension hook especially being formed by 8 font steel ropes and safety hook.
Background technology
The accessory appliances that known petroleum drilling K type derrick is used disassembling, in transfer, installation process is steel rope, steel rope is easily landing in use, to safety, bring hidden danger, and usually fracture of wire, bending, distortion of steel rope, cause and scrap, wasteness is large, the place of application number " 2010105546146 K type derrick dedicated lifting hook " blemish in an otherwise perfect thing is not establish safety lock, during use, hung the likely potential safety hazard of landing from suspension hook of K type derrick, above-mentioned drawback never has good technical scheme and solves.
Summary of the invention
The purpose of this utility model is to provide a kind of safe locking-type K type derrick suspension hook, not only install simple and easy, can not landing, safety factor is reliable, also there will not be steel rope fault, problem on deformation, added again safety lock, further strengthen safety factor, solved well the drawback of above-mentioned simple use steel rope lifting K type derrick.
For achieving the above object, safe locking-type K type derrick suspension hook of the present utility model is achieved in that establishes 8 font steel ropes, and 8 font steel rope tops connect eyelet grommet, bottom connects large ring; If safety lock, safety lock one end connects tapered end, and the other end connects lock to be inserted, and tapered end one side is established lockhole, unblank eye and key are established in top; If safety hook, oblate type lifting hole(eyelet) is established on safety hook 4 tops, crotch is established in bottom, and crotch one side is established large safety eye, a side is established little safety eye.Service routine: by the 8 large rings in font steel rope bottom through the oblate type lifting hole(eyelet) on safety hook top, again eyelet grommet is passed from large ring, stretching, during use, safety lock is arranged on large safety eye and little safe intraocular, lock inserts in lockhole, while opening, use key turns key hole, lock is inserted and is automatically left lockhole.
Adopt such its beneficial effect of structure to be: easy for installation, can not break off relations, safety factor is reliable, can not cause steel rope fault, metaboly.
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
