Higher.
Compared with prior art, the utility model has the beneficial effects that：
1, it is additionally arranged equalizer pulley in the rack of existing rolling open and close machine, which is obliquely installed, with gate
Lifting direction be in one 5 ° ~ 8 angle, in this way, steel wire rope can be passed through from reel after movable pulley, fixed pulley walk back and forth
Another group of movable pulley and fixed pulley are gone to after equalizer pulley ending, in other words, can not be influenced at this time by reel length, it can
Optionally to arrange two sections even more piece reel, the steel wire rope on each section reel corresponds to one group of movable pulley, fixed pulley, through balance
Another group of movable pulley, fixed pulley are gone to after pulley linking, after multigroup movable pulley, fixed pulley carrying, acts on carrying on gate
Lift is on the sunpender being distributed on above gate, and therefore, for large-scale double lifting point hoist engine, the hoist engine of the structural shape can
To ensure the up and down balance system of gate well.
2, stroke monitoring part is provided on the first equalizer pulley and the second equalizer pulley, the stroke monitors part
For displacement sensor.Part is monitored by installing stroke on the first equalizer pulley and second pulley, it will be able to direct measuring steel wire
Rope stroke need not calculate keying stroke by calculating steel wire rope turnning circle and rope drum diameter, and accuracy higher is double hangs
Point balanced type hoist engine provides balanced security.
