Abstract
The utility model is a kind of movable arm tower crane magnification transformable device, comprise torsion releaser, arm head crossbeam, fixed mount and pulley, torsion releaser, fixed mount and pulley are linked together by pin and arm head crossbeam, torsion releaser, fixed mount become " one " font to arrange successively with pulley, fixed mount is between torsion releaser and pulley; Greatly reduce the parts of arm head, there will not be the interference of each parts, structure is simply and mixed and disorderly, and effectively save maintenance cost, function-stable, fault rate reduces greatly.
Description
Technical field
The utility model relates to a kind of movable arm tower crane magnification transformable device.
Background technology
Tower crane is as conventional a kind of construction machinery and equipment, at work, need to realize transforming between multiplying power by the difference location of hook assembly middle pulley group, current most of tower crane still adopts manual switchover, conventional manual zoom rate dolly and suspension hook are roughly divided into two classes, and a class is four multiplying powers; Another kind of is two multiplying powers, but the parts that existing converting means arm head is installed are too much, and space is little, easily occurs the interference of each parts, structure very complicated, make and maintenance cost higher, and functional lability, fault rate is higher.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of movable arm tower crane magnification transformable device, greatly reduces the parts of arm head, there will not be the interference of each parts, structure is simply and mixed and disorderly, effectively saves maintenance cost, function-stable, fault rate reduces greatly.
To achieve these goals, the utility model is achieved through the following technical solutions: a kind of movable arm tower crane magnification transformable device, comprise torsion releaser, arm head crossbeam, fixed mount and pulley, torsion releaser, fixed mount and pulley are linked together by pin and arm head crossbeam, torsion releaser, fixed mount become " one " font to arrange successively with pulley, fixed mount is between torsion releaser and pulley.
Described fixed mount is made up of contiguous block, pin shaft hole, reinforced rib, bearing pin, snubber chain and hanging beam, described contiguous block top has a pin shaft hole, respectively in contiguous block low side both sides fix a reinforced rib, a hanging beam is respectively welded in the bottom surface of reinforced rib, top and the reinforced rib junction of contiguous block have through hole, one end of snubber chain is fixedly connected with one end of bearing pin, and one end of snubber chain is fixedly connected with reinforced rib.
Described hanging beam surface has a through hole, and the diameter of this through hole is identical with the diameter of bearing pin.
Bottom and the reinforced rib junction of described contiguous block have through hole, and the diameter of this through hole is identical with the diameter of bearing pin.
This device changes existing movable arm tower crane magnification transformable structure and mode, baroque swing pulley yoke is replaced with simple suspension hook fixed mount, the position of torsion releaser is moved to the side with arm head pulley symmetry simultaneously, change the baudrier of suspension hook simultaneously, steel rope is directly fixed on after walking around suspension hook on torsion releaser, the conversion of two or four multiplying powers is realized by the Assembly &Disassembly of the suspension hook fixed mount of suspension hook the first half and movable arm tower crane arm head, structure is reliable and simple to operate, effective saving maintenance cost, function-stable, fault rate reduces greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of fixed mount;
In figure: 1, torsion releaser, 2, arm head crossbeam, 3, fixed mount, 4, pulley, 30, contiguous block, 31, pin shaft hole I, 32, reinforced rib, 33, bearing pin, 34, snubber chain, 35, hanging beam.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As depicted in figs. 1 and 2, this movable arm tower crane magnification transformable device, comprise torsion releaser 1, arm head crossbeam 2, fixed mount 3 and pulley 4, torsion releaser 1, fixed mount 3 and pulley 4 are linked together by pin and arm head crossbeam 2, torsion releaser 1, fixed mount 3 arrange successively with 4 one-tenth, pulley " one " font, and fixed mount 3 is between torsion releaser 1 and pulley 4.
Described fixed mount 3 is made up of contiguous block 30, pin shaft hole 31, reinforced rib 32, bearing pin 33, snubber chain 34 and hanging beam 35, described contiguous block 30 top has a pin shaft hole 31, respectively in contiguous block 30 low side both sides fix a reinforced rib 32, a hanging beam 35 is respectively welded in the bottom surface of reinforced rib 32, top and reinforced rib 32 junction of contiguous block 30 have through hole, one end of snubber chain 34 is fixedly connected with one end of bearing pin 33, and one end of snubber chain 34 is fixedly connected with reinforced rib 32.
Described hanging beam 35 surface has a through hole, and the diameter of this through hole is identical with the diameter of bearing pin 33.
Bottom and reinforced rib 32 junction of described contiguous block 30 have through hole, and the diameter of this through hole is identical with the diameter of bearing pin 33.
During use, suspension hook the first half is fixed on fixed mount 3 by pin, transfers suspension hook the latter half, namely realize four multiplying power mode of operations; During two multiplying power work, opened by the connection bearing pin 33 of suspension hook the first half and fixed mount 3, suspension hook top and the bottom are transferred after being combined into entirety, namely realize two multiplying power mode of operations.
