Description
Technical field
The utility model relates to lifting field, specifically reuses short link chain and hangs head assembly for a kind of.
Background technology
In current lifting field, rise and reuse short link chain and be applied to frequently various weight-lifting equipments, for example on the hoisting crane of side, just main using reused the lifting that short link chain carries out freight container.And work the type of attachment of reusing short link chain in prior art, be mainly to rely on ring buckle to be connected on axle, adopt in such a way, if make ring buckle that end float misalignment not occur on adapter shaft, avoid producing and sliding suddenly when lifting, need ring buckle to clamp with axle in the axial direction.But just having there is following drawback in this: can cause ring buckle stuck on the one hand, ring buckle can not be along with the change that produces relative angle between the gravity direction of lift heavy and crane arm in lifting operation, thereby affect its flexible rotating, and when lift heavy, there is unexpected rotation, cannot guarantee the steady of lifting; On the other hand, when the short link chain connecting when ring buckle lower end deflects in hoisting process, can cause the change of ring buckle force status, what make that ring buckle bears is not only the pulling force of lifting, also have the moment of torsion causing because of short link chain deflection, thereby cannot guarantee the safety of ring buckle.
In addition, the ring buckle of this type of attachment and axle, when lifting, produce with axle the position contacting and are always the inside face of ring buckle one end circular arc, thereby easily cause distortion or the fatigue failure at this position.Due to the particularity of container hanging itself, except to hanging head being provided with very high requirement on axle, also had equally the short link chain of reusing have stable connection firm, dismantle demand easily.
Known based on foregoing description, existing short link chain connection mode is difficult to meet the container hanging demand on the hoisting crane of side.For above situation, the utility model proposes a kind of brand-new solution, adopt a kind of short link chain of reusing to hang head assembly and replace traditional type of attachment.
Summary of the invention
For above-mentioned technical matters, the purpose of this utility model is to provide the connecting hanging head assembly of a kind of short link chain and axle.
To achieve the above object of the invention, the utility model adopts following technical scheme:
