The principle of work of suspension hook of the present invention is:
Large-scale crawler crane working condition is complicated, and under different operating modes, the different lift heavy amount of correspondence, therefore usually adopt different winding multiplying powers or different suspension hooks to carry out operation.Present suspension hook generally can't be adjusted deadweight, and under most of operating mode, suspension hook all is in the state of laying particular stress on, and loading capability is hung in impact, sometimes also can have to change Hoisting Program because of laying particular stress on of suspension hook.Larger in order to make each suspension hook can hang the weight of loads under different operating modes, the present invention is designed to suspension hook can adjust flexibly by the combined counterbalance 3 of dismounting both sides the form of deadweight, so just will the large riser 1 of parts and small vertical plate 2 design so large.Make thus the integral body of suspension hook dwindle the tailheaviness reduction, can more steady safety during placement.Make simultaneously the difference of the total weight of combined counterbalance and suspension hook theoretical maximum weight and minimum theoretical weight suitable, thereby and combined counterbalance be formed by stacking the setting range that can increase the suspension hook deadweight by a plurality of fritters.Under the hook-shaped attitude of sky can the prerequisite of free fall, alleviate suspension hook weight and just be equivalent to increase and hang loading capability, simultaneously, because theoretical maximum weight and minimum theoretical weight differ larger, can also guarantee that the user in particular cases still can continue to use same suspension hook at some, for the user offers convenience.
Working process of the present invention is:
Referring to Fig. 3, because every combined counterbalance is all heavier, generally need to be by accessory appliances during installation, the structure of ringbolt a just can be conducive to the use of accessory appliances.As shown in Figure 3, in the present embodiment, four counter sinks and four tapped bore are arranged all on the first combined counterbalance A, the second combined counterbalance B and the 3rd combined counterbalance C.Counter sink on the first combined counterbalance A is corresponding with the tapped bore on large riser 1; Counter sink on the second combined counterbalance B is corresponding with tapped bore on the first combined counterbalance A, and the tapped bore on it is corresponding with counter sink on the 3rd combined counterbalance C, by that analogy.During installation, first with flathead screw b, the first combined counterbalance A is fixed on large riser 1, then the second combined counterbalance B is fixed on the first combined counterbalance A, the 3rd combined counterbalance C is fixed on the second combined counterbalance B, and by that analogy, during dismounting, order is opposite.
