Abstract
The utility model discloses a kind of movable arm type tower machine auxiliary device, at movable arm type tower machine arm end assembling gooseneck boom arm, by taper truss main body and with arm, fixing link span is formed gooseneck boom arm, the taper truss body end of gooseneck boom arm is provided with pulley and auxiliary hook, and arm arm end joint was provided with rope sheave and force-measuring wheel; Auxiliary hook is connected after the steel rope pile warp of drawing from the independent lifting mechanism being arranged on tower head crosses rope sheave, force-measuring wheel and pulley.The independent hoisting operation of little tonnage hoisting capacity can be realized by the reel of independent lifting mechanism, motor and steel rope.The utility model Appropriate application space, structure design is compact, when fully ensureing structural safety, will to be saved and being connected, and realize the dismantled and assembled property of auxiliary by bearing pin with arm end.Integral structure hommization, safe and reliable, good looking appearance.Meet client's large-tonnage tower machine in construction and realize the requirement of low load fast lifting.
Description
One, technical field
The utility model relates to the arm of whip-typed tower crane, the auxiliary device particularly installed additional on crane arm.
Two, background technology
At present, in engineering construction construction operation, little tonnage lifting application is more.And large-scale movable arm type tower machine limits by lifting mechanism, lifting velocity is slower.In guarantee compared with under the prerequisite of big elevating capacity, meet the new direction that little tonnage fast lifting is the development in pluralism of Large Towers machine.
Three, summary of the invention
The purpose of this utility model is to provide a kind of movable arm type tower machine auxiliary device, by installing forehead auxiliary additional in arm end, completes the fast lifting operation of little tonnage with independent lifting mechanism.
The technical solution adopted in the utility model is: a kind of movable arm type tower machine auxiliary device, at movable arm type tower machine arm end assembling gooseneck boom arm, by taper truss main body and with arm, fixing link span is formed gooseneck boom arm, the taper truss body end of gooseneck boom arm is provided with pulley and auxiliary hook, and arm arm end joint was provided with rope sheave and force-measuring wheel; Auxiliary hook is connected after the steel rope pile warp of drawing from the independent lifting mechanism being arranged on tower head crosses rope sheave, force-measuring wheel and pulley.The independent hoisting operation of little tonnage hoisting capacity can be realized by the reel of independent lifting mechanism, motor and steel rope.The utility model Appropriate application space, structure design is compact, when fully ensureing structural safety, will to be saved and being connected, and realize the dismantled and assembled property of auxiliary by bearing pin with arm end.Integral structure hommization, safe and reliable, good looking appearance.Meet client's large-tonnage tower machine in construction and realize the requirement of low load fast lifting.
The utility model not only has the advantage of existing auxiliary version, but also has following distinguishing feature:
A, when fully ensureing structural safety, adopting segmentation pinned connection, being convenient to peace and tearing open, transport.
B, structure design are compact, light and handy, and manufacturing process is simple.
C, effectively increase tower machine lifting alerting ability, save the energy, improve operating efficiency
D, indirectly increase maximum brachium 2 meters, promote lifting range.
