Description
Technical field
The present invention relates to engineering machinery field, particularly relate to roller apparatus, integrative installation technology transport
Bracket and crane.
Background technology
Mobilecrane is as a kind of weight have setting of walking function voluntarily of can be used for hoisting
Standby, it is widely used in engineering machinery field, wherein, crawler crane moves exactly
The one of dynamic formula crane, is that hoisting operation is partially contained on crawler body, and walking relies on carries out
The truss-type cantilever crane structure crane of belting.Along with the quickening of Urbanization in China, economical
Fast development, the scale of state fundamental construction is increasing, needs the weight of article of lifting
And lifting altitude is increasing, crawler crane increasingly shows its superiority, has obtained fast
Violent development.In order to improve crawler crane lifting altitude and work range, it is commonly designed peace
Dress variable-amplitude auxiliary arm.
Due to by transportation clearance and transport heavy quantitative limitation, past before and after hoister in large tonnage operation
Dismount toward needs.As it is shown in figure 1, crawler crane can be dismantled during variable-amplitude auxiliary arm operating mode
Component mainly have main crane arm a1, variable-amplitude auxiliary arm a2, variable-amplitude auxiliary arm after-poppet a3, luffing
Auxiliary fore-stock a4 and variable-amplitude auxiliary arm after-poppet arm-tie a6.First by main crane arm a1 during installation
It is connected with variable-amplitude auxiliary arm a2, then variable-amplitude auxiliary arm fore-stock a4 is connected with variable-amplitude auxiliary arm a2
Connect, finally variable-amplitude auxiliary arm after-poppet a3 is connected with main crane arm a2.Jib assembles complete
After, need to twine between variable-amplitude auxiliary arm fore-stock a4 and variable-amplitude auxiliary arm after-poppet a3 head assembly pulley
Around variable-amplitude steel wire rope a5 and variable-amplitude auxiliary arm after-poppet arm-tie of mating formation on variable-amplitude auxiliary arm after-poppet a3
a6。
In order to prevent propping up after preventing variable-amplitude auxiliary arm fore-stock a4 and variable-amplitude auxiliary arm in transportation
Frame a3 bears the most excessive moment of flexure and is damaged, and existing solution has two kinds:
The first, variable-amplitude auxiliary arm front and back support individually transports.As in figure 2 it is shown, after crane job
Variable-amplitude auxiliary arm fore-stock a4 is disassembled with variable-amplitude auxiliary arm after-poppet a3 and individually transports,
But, along with crawler crane constantly develops to large-tonnage direction, load cases combination the most more comes
The most, jib also does bigger and bigger, and jib kind, arm joint quantity are also done more and more, dismantles operating mode
Many, workload is big, and cost of transportation also greatly increases；
The second, variable-amplitude auxiliary arm front and back support integration transport.As shown in Figure 3 and Figure 4, luffing
Being welded with bracket a7 or sleeper that quantity does not waits on auxiliary fore-stock a4, the structure of bracket a7 is such as
Shown in Fig. 5, during variable-amplitude auxiliary arm operating mode, after jib assembling as shown in Figure 6, become being wound around
During width steel wire rope a5 and assembling variable-amplitude auxiliary arm after-poppet arm-tie a6, in order to prop up after making variable-amplitude auxiliary arm
Frame a3 is not subject to the most excessive moment of flexure, it is common practice that as it is shown in fig. 7, by after variable-amplitude auxiliary arm
At support a3 upper surface A, bearing pin disconnects, and makes the part cantilever support of variable-amplitude auxiliary arm after-poppet a3
On bracket a7, successively at variable-amplitude auxiliary arm fore-stock a4 and variable-amplitude auxiliary arm after-poppet a3 head
It is wound around variable-amplitude steel wire rope a5 between assembly pulley and luffing of mating formation on variable-amplitude auxiliary arm after-poppet a3 is secondary
Arm after-poppet arm-tie a6.During variable-amplitude auxiliary arm front and back support integration transport, by after variable-amplitude auxiliary arm
Frame a3 entirety is placed on above variable-amplitude auxiliary arm fore-stock a4, relies on above variable-amplitude auxiliary arm fore-stock a4
Bracket a7 support.But, auxiliary after-poppet a3 is connected with main crane arm a1 head dumpling point
When connecing, B regional space as shown in Figure 6 is limited, and variable-amplitude auxiliary arm after-poppet a3 is easily and luffing
Auxiliary fore-stock a4 collides, damaged structure part；And variable-amplitude auxiliary arm after-poppet a3 needs
Have certain angle of inclination, due to different brachiums combine main crane arm a1 and variable-amplitude auxiliary arm a2 it
Between angle inconsistent, cause variable-amplitude auxiliary arm after-poppet a3 and main crane arm a1 head dumpling point phase
During connection, 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 during concrete installation variable-amplitude auxiliary arm after-poppet a3, affects installation effectiveness；
Additionally, variable-amplitude auxiliary arm front and back support integration means of transportation as shown in Figure 3 lacks effective solid
Fixed, safeguard procedures etc., need extra to be fixed, protection etc., and this allows for structure more
Complexity, exploitativeness is poor.
Summary of the invention
For overcoming above technological deficiency, present invention solves the technical problem that and be to provide a kind of running roller dress
