Description
Technical field
The present invention relates to engineering machinery field, particularly relate to roller apparatus, integrative installation technology pallet for transporting and hoisting crane.
Background technology
Movable crane is as a kind of weight have the equipment of walking function voluntarily of can be used for hoisting, be widely used in engineering machinery field, wherein, crawler crane is exactly the one of movable crane, be that hoisting operation part is contained on crawler body, walking relies on the truss-type cantilever crane structure hoisting crane of crawler attachment.Along with the quickening of Urbanization in China, economic fast development, the scale of state fundamental construction is increasing, and weight and the lifting altitude of the article of needs lifting are increasing, and crawler crane more and more shows its preceence, obtains swift and violent development.In order to improve crawler crane lifting altitude and work range, usual design and installation variable-amplitude auxiliary arm.
Owing to being subject to transportation clearance and transport heavy quantitative limitation, often need before and after hoister in large tonnage operation to carry out dismounting.As shown in Figure 1, during variable-amplitude auxiliary arm operating mode, the demountable component of crawler crane mainly contains main crane arm a1, variable-amplitude auxiliary arm a2, variable-amplitude auxiliary arm after poppet a3, variable-amplitude auxiliary arm front frame a4 and variable-amplitude auxiliary arm after poppet arm-tie a6.First main crane arm a1 is connected with variable-amplitude auxiliary arm a2 during installation, then variable-amplitude auxiliary arm front frame a4 is connected with variable-amplitude auxiliary arm a2, finally variable-amplitude auxiliary arm after poppet a3 is connected with main crane arm a2.After jib assembling, need between variable-amplitude auxiliary arm front frame a4 and variable-amplitude auxiliary arm after poppet a3 head assembly pulley, to be wound around variable-amplitude steel wire rope a5 and the variable-amplitude auxiliary arm after poppet arm-tie a6 that mats formation on variable-amplitude auxiliary arm after poppet a3.
In order to prevent preventing variable-amplitude auxiliary arm front frame a4 and variable-amplitude auxiliary arm after poppet a3 from bearing additionally excessive moment of flexure and being damaged in transportation, existing solution has two kinds:
The first, variable-amplitude auxiliary arm front and back support transports separately.As shown in Figure 2, after crane job, variable-amplitude auxiliary arm front frame a4 and variable-amplitude auxiliary arm after poppet a3 is disassembled and transport separately, but, along with crawler crane is constantly to large-tonnage future development, load cases combination also gets more and more, and jib also does larger and larger, jib kind, arm joint number amount are also done more and more, dismounting operating mode is many, and work capacity is large, and traffic cost also greatly increases;
The second, variable-amplitude auxiliary arm front and back support integration transport.As shown in Figure 3 and Figure 4, variable-amplitude auxiliary arm front frame a4 is welded with quantity not wait bracket a7 or sleeper, the structure of bracket a7 as shown in Figure 5, during variable-amplitude auxiliary arm operating mode, after jib assembling as shown in Figure 6, when being wound around variable-amplitude steel wire rope a5 and assembling variable-amplitude auxiliary arm after poppet arm-tie a6, additionally excessive moment of flexure is not born in order to make variable-amplitude auxiliary arm after poppet a3, usual way is as shown in Figure 7, variable-amplitude auxiliary arm after poppet a3 upper surface A place bearing pin is disconnected, make the part cantilever support of variable-amplitude auxiliary arm after poppet a3 on bracket a7, variable-amplitude steel wire rope a5 is wound around successively and the variable-amplitude auxiliary arm after poppet arm-tie a6 that mats formation on variable-amplitude auxiliary arm after poppet a3 between variable-amplitude auxiliary arm front frame a4 and variable-amplitude auxiliary arm after poppet a3 head assembly pulley.During variable-amplitude auxiliary arm front and back support integration transport, variable-amplitude auxiliary arm after poppet a3 entirety is placed on above variable-amplitude auxiliary arm front frame a4, relies on the bracket a7 above variable-amplitude auxiliary arm front frame a4 to support.But when auxiliary after poppet a3 is connected with main crane arm a1 head dumpling point, B regional space is as shown in Figure 6 limited, variable-amplitude auxiliary arm after poppet a3 easily and variable-amplitude auxiliary arm front frame a4 collide, damaged structure part; And variable-amplitude auxiliary arm after poppet a3 needs certain angle of inclination, the angle combined between main crane arm a1 and variable-amplitude auxiliary arm a2 due to different brachium is inconsistent, when causing variable-amplitude auxiliary arm after poppet a3 to be connected with main crane arm a1 head dumpling point, the angle of inclination of variable-amplitude auxiliary arm after poppet a3 is inconsistent when different brachium combination, its angle of inclination of more difficult control when concrete installation variable-amplitude auxiliary arm after poppet a3, affects installation effectiveness; In addition, variable-amplitude auxiliary arm front and back support as shown in Figure 3 integration transportation mode lacks that actv. is fixed, safeguard procedures etc., needs extra to be fixed, protection etc., and this just makes structure more complicated, and exploitativeness is poor.
