Wherein: 1. the lifting hook comprises a lifting hook 101, a large hook arm 102, a small hook arm 103, a lifting hole 104, a safety handle 105, a convex block 2, a lifting ring 3, a lifting rope 301, a butterfly buckle 4, a connecting ring 5, a ring forging piece 6 and a shackle.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. In the present invention, unless otherwise expressly stated or limited, the terms "disposed," "mounted," "connected," and "fixed" are to be construed broadly, e.g., as meaning either a fixed connection or a removable connection; may be a mechanical connection; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
As shown in fig. 1 to 3, a complete pile hoisting sling for ring forging comprises a lifting hook 1, a lifting ring 2 and a sling 3, wherein the lifting ring 2 is fixedly connected with the lifting hook 1 through the sling 3, and the lifting ring 2 is connected with the sling 3 through a connecting ring 4. The lifting hook 1 comprises a large hook arm 101, a small hook arm 102 and a safety handle 104, wherein a lifting hole 103 is formed in the upper end of the large hook arm 101. 3 lower extremes of hoist cable are connected butterfly and are buckled 301, the hoist cable is connected to butterfly and detain 301 one end, and the butterfly is buckled 301 other end and is connected lifting hook 1 through shackle 6. The safety handle 104 is disposed on the large hook arm 101, and the end of the small hook arm 102 is provided with a projection 105 projecting toward the inner side of the small hook arm 102. The included angle between the big hook arm 101 and the small hook arm 102 is more than 45 degreesoAnd said included angle is less than 90 degreeso. The safety handle 104 is disposed outside the hook arm 101. The included angle between the convex block 105 and the small hook arm 102 is 90 degreeso. The slings 3 comprise three groups, and the three groups of slings 3 are respectively connected with the three groups of lifting hooks 1.
The specific working principle is as follows: in the time of actual use, the rated load is promoted to 17 tons from 4 tons, has improved work efficiency, and when the hot ring spare was transported, operational environment had been improved, has reduced intensity of labour. The standard 120-level RUD whole set of three-limb chain rigging is adopted, under the standard plant height, the inclination angle of the sling 3 is increased, the radial moment is increased, the whole stack of annular forging pieces 5 form self-locking under the action of gravity, and the safety risk that the whole stack of annular forging pieces 5 slide down is avoided. The lifting hook 1 is made of 42CrMo4, the yield strength of more than 890Mpa is obtained through quenching and tempering heat treatment, the rated load of the lifting appliance is increased from 4 tons to 17 tons, the operation efficiency is improved, and the overall weight of the lifting appliance is reduced. The working condition of the operator is improved, the safety handrail 104 is increased, the chance of squeezing the hand of the operator is avoided, and the safety risk is reduced.
When the lifting hook is used, the three groups of lifting hooks 1 are hung at the bottom of the ring forging 5, the lug 105 is clamped at the bottom of the ring forging 5, an operator can adjust and lift the lifting hook in place by holding the safety handle 104, and the operator is not allowed to grasp the whole lifting hook. Gripping the entire hook 1 with the hand may be in intimate contact with the loop, creating a hand pinching risk. Because the contained angle between big hook arm 101 and the little hook arm 102, lifting hook 1 is under the complete circumstances of hooking, and the inner ring card of ring forging 5 is in lug department, and the outer loop card of ring forging 5 is on big hook arm 101, and when whole hoist hung ring forging 5, under the effect of the gravity of whole buttress ring forging 5, lifting hook 1 formed the auto-lock with ring forging 5, and in actual production, lifting hook 1 material was 42CrMo4, obtains 890Mpa through quenching and tempering thermal treatment, has promoted lifting hook 1's bearing capacity greatly, has also promoted the transportation volume of whole hoist and has carried promptly. After the transfer is finished, the lifting hook 1 is dropped on the idle stop of the material rack, the gravity of the ring forging piece 5 is borne by the material rack, the lifting hook is unhooked smoothly, and the transfer is finished.
To sum up, the utility model discloses reach anticipated purpose.
