Description
Technical field
The utility model relates to engineering machinery field, relates in particular to a kind of single multiplying power load hook and has the hoisting crane of this list multiplying power load hook.
Background technology
Along with the development of crawler crane to the large-tonnage direction, the operating mode combination is more and more, and the model of load hook (hereinafter all being called for short " suspension hook ") also constantly increases, and the problem that suspension hook runs in the operation process also highlights in succession.In theory, hoisting crane has a rated load weight corresponding with its model, and the size of this rated load weight should equal the weight of suspension hook and the total weight of the weight that carries that hangs.Therefore, under the certain situation of the model of hoisting crane, when namely rated load weight was definite value, the weight of suspension hook was more light more good.
But, in a single day the weight of suspension hook alleviate, with occur under the empty hook-shaped attitude can't free fall may, its reason is: the free fall of suspension hook need overcome the resistance that pulley bearings brings and the resistance that is produced by the steel rope self gravitation, highly higher and suspension hook twines multiplying power when big in lifting, and the resistance that need overcome is corresponding bigger; Otherwise highly lower and twine multiplying power more after a little while in lifting, the resistance that need overcome is corresponding less.
What Fig. 1-3 showed is the structural representation of present employed suspension hook.As Figure 1-3, present employed suspension hook comprises outer weight 1 ', pedestal 2 ' and gib head assembly 3 ', and wherein: outer weight 1 ' is hood-shaped structure, and its top has a groove 11 ' and a plurality of through holes 12 '.The top of pedestal 2 ' is provided with hanger, and both are integrally manufactured.Down offer first tapped bore 21 ' from the top of pedestal 2 ', the bottom of pedestal 2 ' has a groove 22 ' and second tapped bore 23 '.After groove 11 ' on the outer weight 1 ' is inserted in from pedestal 2 ' top, first tapped bore 21 ' of using bolt 4 ' to insert on the pedestal 2 ' from the through hole 12 ' on the outer weight 1 ' again is just outer weight 1 ' and pedestal 2 ' can be fixed together (as Fig. 2, shown in Figure 3).
Gib head assembly 3 ' comprises coupler body 31 ', has block 32 ' and the nut 33 ' of central through hole, and coupler body 31 ' passes from the central through hole of block 32 ', and its coupling end is exposed outside, and this coupling end is threaded with nut 33 '.Coupler body 31 ' is rotationally connected by bearing (not shown) and block 32 '.The sidewall of nut 33 ' offers the hole of running through space, bearing place, as the oil hole 34 ' that injects grease.Block 32 ' offers the through hole 35 ' that parallels with its axial line, utilizes bolt 4 ' just can insert second tapped bore 23 ' of pedestal 2 ' from the bottom of through hole 35 ', makes gib head assembly 3 ' can be connected the bottom of pedestal 2 '.

But, because theoretical maximum gravimetric value and above-mentioned minimum theoretical weight differs greatly, therefore, depend merely on and carry out balance by the weight that increases outer weight 1 ' and can't adapt to the various combination operating mode.For example, if suspension hook consider the theoretical maximum gravimetric value and make, lay particular stress on when this suspension hook is used under rest working conditions.In rated load weight one timing of hoisting crane, its total weight that can hang the weight that carries will reduce, and namely hang loading capability and descend.So just cause originally under certain operating mode, can also continuing to use this suspension hook to hang loads, but because laying particular stress on, can enough hang by suspension hook the rated load weight that the weight total weight that carries exceeds this hoisting crane, the suspension hook (lighter suspension hook) that more renews even use more that the large-tonnage hoisting crane could satisfy working condition requirement of at this moment just having to.Like this, will inevitably increase cost, and, also can bring more inconvenience to the user.
In addition, as seen from Figure 3, oil hole 34 ' is covered by outer weight 1 ', each outer weight 1 ' and pedestal 2 ' of need dismantling when grease-added, use inconvenience.Simultaneously, existing pedestal 2 ' and the hanger above it are processed by an integral body, and the work material degree of utilization of part is lower, and the course of processing is comparatively loaded down with trivial details, and manufacturing cost is higher.
