Abstract
The utility model discloses a kind of lifting hook pulley group, comprise bracing frame, be assemblied in two pulleys on bracing frame, the lifting beam with hook be located on bracing frame, rotate the suspension hook that is assemblied on lifting beam with hook, the support frame as described above left and right sides is respectively equipped with the sheave shaft extended in left-right direction, described two pulley rotation are assemblied on corresponding sheave shaft, described lifting beam with hook is between two pulleys, the pivot center of described lifting beam with hook is vertical with the pivot center of sheave shaft, and the pivot center of described lifting beam with hook is positioned at the top of the lower surface of pulley.Lifting beam with hook is located between two pulleys by the utility model, and the pivot center of lifting beam with hook is in the top of the lower surface of pulley, the fixed position of suspension hook is moved, compare existing lifting beam with hook and be in lifting hook pulley group below pulley, the limit of the lifting altitude of hoisting crane can be made to increase, the height of lifting heavy can be made to increase.
Description
Technical field
The utility model relates to crane field, is specifically related to a kind of lifting hook pulley group.
Background technology
The lifting hook pulley group of existing hoisting crane, as shown in Figure 1, comprise pulley 100, sheave shaft 101 and suspension hook 106, two pulleys 100 rotate and are assemblied on a sheave shaft 101, sheave shaft 101 is installed on bracing frame, boatswain chair 102 is provided with between two pulleys 100, boatswain chair 102 rotated down is provided with lifting beam with hook 105, lifting beam with hook 105 upper and lower end face offers the clear opening for wearing suspension hook, and the neck of hook upper end of suspension hook 106 passes the clear opening of lifting beam with hook 105 and is set with thrust baring 104 and hook nut 103 successively.The lifting hook pulley group of this structure, lifting beam with hook 105 is in the below of pulley 100, and namely the pivot center of suspension hook 106 is in the below of pulley 100, adds the length that suspension hook is in the part below lifting beam with hook, have impact on the limes superiors of the sling height of hoisting crane.In addition, boatswain chair 102 downward extension portion is longer, and during hoisting heavy, when steel rope tilts, when suspension hook is subject to oblique pulling, boatswain chair 102 is subject to larger moment of flexure, and boatswain chair 102 easily deforms.
Summary of the invention
The purpose of this utility model is to provide a kind of suspension hook arrangement form rational lifting hook pulley group, obtains the larger lifting altitude upper limit to make hoisting crane.
To achieve these goals, the utility model adopts following technical scheme: a kind of lifting hook pulley group, comprise bracing frame, be assemblied in two pulleys on bracing frame, be located at the lifting beam with hook on bracing frame, rotate the suspension hook be assemblied on lifting beam with hook, the support frame as described above left and right sides is respectively equipped with the sheave shaft extended in left-right direction, described two pulley rotation are assemblied on corresponding sheave shaft, described lifting beam with hook is between two pulleys, the pivot center of described lifting beam with hook is vertical with the pivot center of sheave shaft, the pivot center of described lifting beam with hook is positioned at the top of the lower surface of pulley.
Described suspension hook has the neck of hook, and described lifting beam with hook is provided with the clear opening of the neck of hook for wearing suspension hook, and the neck of hook upper end of described suspension hook passes clear opening and is set with successively and is supported in bearing above lifting beam with hook and hook nut.
Described hook nut lower surface is axially arranged with the containing cavity for placing bearing along it.
The upper surface of described lifting beam with hook is planar structure, and the upper surface of described lifting beam with hook coordinates with bearings.
The beneficial effects of the utility model are: lifting beam with hook is located between two pulleys by the utility model, and the pivot center of lifting beam with hook is in the top of the lower surface of pulley, the fixed position of suspension hook is moved, compare existing lifting beam with hook and be in lifting hook pulley group below pulley, the limit of the lifting altitude of hoisting crane can be made to increase, the height of lifting heavy can be made to increase.Two pulleys are installed on respectively on spaced two sheave shafts, between two pulleys, leave the space of installing lifting beam with hook, non-interference.The arrangement form of the utility model suspension hook also can avoid the boatswain chair of existing installation lifting beam with hook longer to downward-extension and the yielding problem of appearance that is that cause simultaneously.
