After rope cramp, then with the tensioning apparatus on amplitude variation trolley and rope sheave it is connected and is tensioned, the tensile force of variable-amplitude steel wire rope makes tulwar
Afterbody is slightly lifted, and this state is remained when amplitude variation trolley works, and ensures control of the variable-amplitude steel wire rope to amplitude variation trolley.
When tower crane variable-amplitude steel wire rope is broken, there is no tensile force, horizontal balancing weight to exist for variable-amplitude steel wire rope in tulwar fixture block rope cramp
Drive tulwar fixture block afterbody to move downward rapidly under Action of Gravity Field, and cutter head is lifted 80 degree rapidly, the cutter head insertion tower lifted
In horn frame lower edge, cutter head is collided and is stuck on the horizontal web member of arm support lower edge, makes the amplitude variation trolley for losing variable-amplitude steel wire rope control fast
Speed stops.Because the present invention can be such that amplitude variation trolley stops rapidly, avoid variable-amplitude steel wire rope and break when variable-amplitude steel wire rope is broken
Accident caused by splitting, reduce user and the construction party person and property loss, ensure that derrick crane in variable-amplitude steel wire rope
Post-rift safety.The present invention is simple in construction, reasonable in design, becomes if realizing middle-size and small-size horizontal arm tower crane and being met during load is hung
It is dangerous caused by avoiding amplitude variation trolley therefore reason being out of control during width wire cable rupture.Meanwhile the present invention also fundamentally ensures
Safety device surprisingly lifts when amplitude variation trolley gearshift accelerates, turned to suddenly, and causes fracture and the arm support of tower crane variable amplitude rope
The damage of string pipe or protection device in itself, security and safety when being effectively guaranteed the work of flat-top tower crane luffing fill
The reliability put, and the blank of such stop device has been filled up, it is worth extensive popularization and application.
