The crane hook disclosed by the invention is exquisite in structure and convenient to use, and can achieve single-hook and double-hook operation, so that the flexibility of lifting operation is improved.

Description

A kind of crane hook

Technical field

The present invention relates to mechanical field, particularly a kind of crane hook.

Background technology

Suspension hook is modal a kind of suspender in elevator machinery.Suspension hook is often divided into single hook and double hook at the steel rope hook of lifting mechanism by shape by means of member hangs such as assembly pulleys; Be divided into forging suspension hook and stacked suspension hook by manufacture method, single hook manufacture is simple, easy to use, but stressing conditions is bad, is mostly used in the workplace that hoisting capacity is less than 80 tons; Hoisting capacity adopts the double hook of stressed symmetry greatly often.Stacked suspension hook is riveted by the steel plate of several pieces cutting formings and is formed, and when crackle appears in indivedual sheet material, whole suspension hook can not destroy, and safety is better, but deadweight is comparatively large, is mostly used in big elevating capacity or handling molten steel is contained on the hoisting crane of bucket.Suspension hook is often hit in operation process, must adopt the Fine Steel Casting iron manufacture of good toughness.Suspension hook classification is extremely wide, generally comprise: shackle, suspension ring, annulus, pyriform ring, long suspension ring, combination suspension ring, S hook, nose suspension hook, American suspension hook goat's horn suspension hook, eye shape Slip Hook, band insurance card ringbolt, chain shackle, there is uniqueness, novelty, of fine quality, safe feature, be applicable to factory, mine, oil, chemical industry and boats and ships harbour etc.

Summary of the invention

Technical matters to be solved by this invention is to provide a kind of delicate structure, easy to use, can realize single hook and double hook operation, improve the crane hook of the alerting ability of hoisting operation, to solve the above-mentioned multinomial defect caused in prior art.

For achieving the above object, the invention provides following technical scheme: a kind of crane hook, by main hook body, slip ring, jam nut, clip, spring, steel bolt, bead, auxiliary hook body, captive nut and bolt of rear end plate composition, slip ring is welded on main hook body, auxiliary hook body button is embedded on slip ring, fixed by captive nut, the back of main hook body and auxiliary hook body is plane, two coupler body backs are against back, clip is arranged on the neck of main hook body, be fixed on main hook body by bolt of rear end plate, steel bolt is arranged on clip, fixed by jam nut, spring one end is hooked on clip, the other end is hooked on steel bolt, the end of steel bolt is buckled in bead, bead is located at the end of main hook body.

Preferably, described main hook body and auxiliary hook body are provided with concave and convex stripe.

Preferably, described slip ring is provided with polytetrafluorethylecoatings coatings.

Preferably, described spring is bifilar crosslinked spring.

Preferably, described steel bolt, is made up of pole, movable axis, key and buckle, and pole is arranged on the end of key by movable axis, and buckle is located at the head end of key.

The beneficial effect of above technical scheme is adopted to be: the Suspension hook structure of such design is exquisite, easy to use, can realize single hook and double hook operation, improve the alerting ability of hoisting operation; Main hook body and auxiliary hook body are provided with concave and convex stripe, and such design increases the friction force of coupler body, prevent the phenomenon that goods slippage occurs during hook block goods; Slip ring is provided with polytetrafluorethylecoatings coatings, the wear-resisting scuff of this coating, and the friction coefficient on surface is little, can play the effect that smooth auxiliary hook body slides; Spring is bifilar crosslinked spring, and such design increases hardness and the coefficient of tension of spring, can be tighter block bead, play the protective effect to goods, prevent goods slippage, slow down the aging of spring simultaneously, extend the service life of spring; Steel bolt; be made up of pole, movable axis, key and buckle; pole is arranged on the end of key by movable axis; buckle is located at the head end of key; it is flexibly more convenient that such design makes steel bolt use; the design of buckle makes steel bolt more firmly block bead, serves protective effect to goods.
