Heavy-duty machine.
Background technology
At present, the Telescopic boom mechanism of crane is mainly linear Telescopic boom mechanism (hereinafter referred to as straight-arm telescoping mechanism),
Generally, the straight-arm telescoping mechanism of single oil cylinder does not allow band load flexible.
On the one hand, for arranging the straight-arm telescoping mechanism of assembly pulley and suspension hook at arm head, substantially can meet and have necessarily
Span hang load requirement, and for directly at the straight-arm telescoping mechanism of minor details arm arm head mounting hanger, carry out hanging of certain span
When carrying operation and have barrier between crane and weight, hang load the most relatively difficult.
As it is shown in figure 1, Fig. 1 is that a kind of face-up transporting hoist of container crane with straight-arm telescoping mechanism is (the most straight
Arm front handling mobile crane) hang load operating mode.
Hanging as a example by load operating mode by diagram, this straight-arm front handling mobile crane cannot directly hang the container carrying the 3rd row top, now needs
First the container crane at first row (the most front two rows) top carried the container at the 3rd row top from rear just can hanging, and to there is arc
The face-up transporting hoist of container crane (hereinafter referred to as arched arm front handling mobile crane) of shape Telescopic boom mechanism can directly hang load the 3rd row top
Container and without removing the container of first row (or front two rows) in advance.
The technical problem underlying that above-mentioned straight-arm telescoping mechanism exists has:
When minor details arm arm head mounting hanger, it is impossible to or be difficult to carry out to have span and there is the operation of obstacle, the most right
In straight-arm front handling mobile crane, cannot directly carry out hanging load operation across case under operating mode shown in Fig. 1, not only reduce work when real work
Make efficiency, also take up bigger work place, add Financial cost.
On the other hand, traditional hydraulic cylinder adds the single oil cylinder straight-arm telescoping mechanism of rope formula and does not allow band load flexible, and energy
The straight-arm telescoping mechanism (such as the Telescopic boom mechanism of straight-arm front handling mobile crane) that enough band loads are stretched cannot be directly used to again realize arc and stretches
Stretching of arm mechanism.
Additionally, for straight-arm front handling mobile crane, it is not easy to the satisfied load of hanging hanging the load following weight of horizontal plane requires (such as to hang load harbour
Container on the following ship of plane), now need to increase other devices or use special suspender this to hang load requirement realizing,
And there is the front handling mobile crane of arc Telescopic boom mechanism, it is not necessary to increase other auxiliary device, it is possible to be easy to hang below load horizontal plane
Weight.
In view of this, how to design and a kind of can carry flexible and that arc line shaped motion can be realized Telescopic boom mechanism by band, enter one
Step improve crane especially front handling mobile crane stacking efficiency and increase crane working space be those skilled in the art urgently
Technical problem to be solved.
