Detailed Description
For a further understanding of the contents, features and effects of the present invention, reference will now be made to the following examples, which are to be considered in conjunction with the accompanying drawings. It should be noted that the present embodiment is illustrative, not restrictive, and the scope of the utility model should not be limited thereby.
A recyclable cover beam steel bar lifting appliance comprises a lifting steel frame 1, a high-strength manganese steel chain 4 and a movable anchor hook; four corners of the top of the hoisting steel frame are connected with a lifting hook of a crane through steel wire ropes, and a plurality of lifting lugs 2 are uniformly and fixedly arranged at the bottom of the hoisting steel frame; the lifting lugs are hung with length-adjustable high-strength manganese steel chains, and the lower parts of the high-strength manganese steel chains are hinged with a plurality of movable anchor hooks which extend into the mesh holes of the reinforcing steel bar frame in a vertical posture and hoist the reinforcing steel bar frame in a horizontal posture.
The movable anchor hook comprises a steel anchor ear 5, a convex shaft 9 and a hook plate 6, wherein the steel anchor ear is connected and fixed on the binding belt, and the two side walls of the steel anchor ear are symmetrically and fixedly provided with the convex shaft extending along the horizontal direction; the top surface of the middle part of the hook plate is provided with a hanging lug 8, and two ends of the hook plate are bent upwards; the hanging lug is circumferentially rotated and axially limited and hung on the convex shaft.
And the high-strength manganese steel chain is of an intermittent structure, and a length regulator 3 is connected between the bottom end of the upper-section high-strength manganese steel chain and the top end of the lower-section high-strength manganese steel chain in an adjusting way.
And the lower part circumference of high strength manganese steel chain sets firmly bandage 7, and the hook plate of vertical gesture is fixed in this bandage ligature.
To more clearly illustrate the embodiments of the present invention, an example is provided below:
the recyclable bent cap steel bar lifting appliance solves the problem that a steel bar cage in the prior art is difficult to lift, a plurality of lifting hooks and steel bars inside the steel bar cage do not need to be bound, the construction difficulty of 'upper hooking' and 'lower hooking' of the lifting appliance is reduced, the movable anchor hook is simple in structure, strong in bearing capacity and capable of being repeatedly used, the steel bar structure inside the steel bar cage cannot be damaged, and the unhooking risk is effectively reduced.
