Description
Technical field
The utility model is related to crane field, more particularly, to a kind of suspender.
Background technology
Crane need to possess lifting mechanism, drive article elevating movement.Wirerope-winding mechanism is the important of transmission system
Part, linear motion is changed over by rotary motion, plays the conversion of forms of motion and the transmission effect of energy.Wire rope winding machine
Structure is broadly divided into following three kinds of forms：
1st, two suspension centres lifting form, the oblique pull in this structure type only one of which direction, therefore run and rotate in lifting cargo
During wave and rock serious, it is dangerous big, be only applicable to work infrequently, the low and less demanding occasion of efficiency.
2nd, four-point lifting lifting form, forms 4 redundant structures of the same suspender of raising, and each suspension centre is all one
Inverted triangle, the swing in the horizontal plane of control suspender.The static determinacy model of mechanics is that 3 points determine a plane, and a plane has
Four suspension centres, are carried by eight steel wire ropes, can form unbalance stress.Because the reel of control rope is more, process and fabrication and installation
Light Difference, will result in steel wire rope unbalance stress, finally result in some steel wire ropes fragile.Therefore, this structure type structure
Complexity, parts are various, high to manufacturability requirement, and manufacture difficulty is big, and difficult using field maintenance.
3rd, the rope of container eight winding form, is the improvement in the structure of four-point lifting lifting form, forms 4 raisings same
The redundant structure of one suspender, each suspension centre is all an inverted triangle, controls suspender swing in the horizontal plane.This structure type
Although it is two multi-joint reels that multiple reels are simplified, angle pulley increases to 12 by 2, and excessive pulley is in space
Numerous and diverse space three-dimensional arrangement, finally lower eight ropes are in four inverted-triangulars, although performance, but steel wire rope can be ensured through multiple
, easily there is fatigue and unbalance stress in multidirectional steering, causes service life to reduce.Pulley arrangements are intricate, and steel wire rope is small
Plane is crisscross on car, makes making and processing request high, causes holistic cost high.
