Since the axis arranged of all movable pulleys on same straight line, so in directions X (shown in Figure 6), there is the possibility of rocking in load;
2. the steel rope intersection is twined, and is difficult to verify whether steel rope interferes each other;
3. its suspension hook is in the process that hoists and descend, at the XOZ graphic memory in horizontal deflection.
Summary of the invention
The present invention is intended to the shortcoming and defect part that in above-mentioned technology, exists, and a kind of hoisting mechanism for crane of high position precision is provided; This mechanism is not only reasonable in design, and knot hooks and gathers, and has both realized that another root steel rope of steel cable fracture back can maintain load; Avoid the mutual interference of steel rope again effectively; And have and do not rock, the suspension hook horizontal deflection is little, and the position precision is high; Hoist steadily, safe operation reliable with use advantages such as very convenient.
The objective of the invention is to adopt following technical scheme to realize: the hoisting mechanism for crane of described high position precision; Comprise electric winch, steel rope, fixed pulley, movable pulley and suspension hook; It is characterized in that:, prop up top of the trellis at fixed pulley and install orthogonal A pulley and B pulley from top to bottom in regular turn with installing fixed pulley support on the corresponding trolley frame in electric winch position; Below the fixed pulley support, moving pulley bracket is set; The hinged suspension hook in the bottom of described moving pulley bracket; Install E pulley, F pulley, G pulley, H pulley, D pulley and C pulley in regular turn on the moving pulley bracket more than its suspension hook, described C pulley, F pulley and G pulley and B pulley are in the same vertical plane; Described D pulley, E pulley and H pulley and A pulley are in the same vertical plane; Described A steel rope is after reel is drawn; Walk around E pulley, H pulley, A pulley and D pulley in regular turn, finally be fixed on an end of equilibrium arm, described B steel rope is after reel is drawn; After walking around G pulley, F pulley, B pulley and C pulley in regular turn, finally be fixed on the other end of equilibrium arm.
Described equilibrium arm is installed in a side of trolley frame end face.
Because the present invention. 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 realizes the object of the invention.
Characteristics of the present invention 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 present invention 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.
