Described equilibrium arm is installed in a side of trolley frame end face.
Because the utility model. through reasonable Arrangement C pulley, D pulley, E pulley, F pulley, G pulley and H pulley; Make the A steel rope walk around D pulley, E pulley and H pulley; The B steel rope is walked around after C pulley, F pulley and the G pulley, and A steel rope and B steel rope are the space symmetric arrangement, to guarantee the lifting mechanism on period; Suspension hook does not rock, and horizontal deflection reduces; The top D pulley that the C pulley is installed on moving pulley bracket is installed on middle; E pulley, F pulley, G pulley and H pulley are installed on the bottom; And E pulley and H pulley be on same horizontal surface, and be lower than the horizontal surface at the axis place of F pulley and G pulley, and actv. has been avoided the steel rope interference.
The comprehensive above technical scheme of being taked, the purpose of realization the utility model.
The characteristics of the utility model are:
1, reduced in original lifting mechanism load perpendicular to rocking in the plane of movable pulley axis;
2. it is clear and definite that steel rope twines the path, and actv. has been avoided the steel rope interference;
3. reduced in original lifting mechanism working process, the horizontal deflection of suspension hook has improved accuracy of positioning.
Therefore, the utility model is not only reasonable in design, and knot hooks and gathers; Both realized steel cable fracture back and another root steel rope can also maintain load, avoided the mutual interference of steel rope again effectively, and had and do not rock; The suspension hook horizontal deflection is little; Accuracy of positioning is high, hoist steadily, safe operation reliable with use advantages such as very convenient.
