[0001] The utility model relates to the technical field of bridge cranes, in particular to a practical three-in-one speed reducer installation and reinforcement device for a rotating hoist of an overhead crane. Background Art

[0002] In the steel processing industry, the transfer of steel billets is usually achieved through the use of slings hoisted by bridge cranes. Slings are divided into non-rotating slings and rotatable slings. Rotatable slings are more flexible and can achieve the turning, loading and unloading and stacking of steel billets. Therefore, they are widely used in steel production and transshipment.

[0003] Bridge cranes usually use motors and three-in-one reducers to achieve the rotation of rotating spreaders, and the motors and three-in-one reducers are generally fixed directly to the bridge crane body by bolts. During the start-up and stop process of the three-in-one reducer, the impact load generated by it is converted into shear force and all acts on the bolts. The bolts are often loosened or even broken by this shear force, causing the overall displacement of the three-in-one reducer, resulting in meshing dislocation when the three-in-one reducer drive gear drives the rotating spreader to rotate. In severe cases, the output shaft of the three-in-one reducer may break, causing major equipment accidents and affecting normal production operations. Utility Model Content
