Specific embodiment
As shown in Figure 1, the special-shaped cantilever crane that a kind of drag chain is built-in, including special-shaped level-one arm, telescopic arm 1 and drag chain 2.
The abnormity level-one arm includes end to end first straight-arm 3 and the second straight-arm 4, first straight-arm 3 and second
The angle of straight-arm 4 is greater than 0 ° and less than 180 °.The tail end of first straight-arm 3 is mounted on the base, and can be rotated on pedestal.
The telescopic arm 1 is sleeved on the second straight-arm 4 and can be flexible along the second straight-arm 4.
Such as Fig. 3, the fixing end of the drag chain 2 is fixed in the first straight-arm 3, and the mobile terminal of the drag chain 2 is fixed on flexible
The tail portion of arm 1.Bending plate 9 is provided in first straight-arm 3, the wavy coiling in the middle section of the drag chain 2 is arranged in bending
In the cavity of the inner wall of plate 9 and the first straight-arm 3 composition.Bending plate 9 plays the role of limition orientation, makes drag chain during exercise will not edge
Perpendicular to the direction play of the first straight-arm 3.Telescoping cylinder drives telescopic arm 1 when carrying out stretching or retract action, and drag chain 2 is driven to roll
It is dynamic to move ahead or move back.
Such as Fig. 2, the tail portion of the telescopic arm 1 is provided with connecting plate 8, and the mobile terminal pin joint of the drag chain 2 is in connecting plate 8
On.The part that the drag chain 2 is located in telescopic arm 1 is provided with the guiding mechanism that positioning is turned to for drag chain 2.The guiding mechanism
Upper directive wheel 5 and lower directive wheel 6 including being oppositely disposed in 2 two sides of drag chain, the upper directive wheel 5 and lower directive wheel 6 and drag chain 2
The tangential direction of joint is parallel to the telescopic direction of telescopic arm 1.The center of the upper directive wheel 5 and lower directive wheel 6 is set respectively
It is equipped with directive wheel pin shaft 10 and lower directive wheel pin shaft 11, the upper directive wheel pin shaft 10 and lower directive wheel pin shaft 11 are fixed on folding
On bent plate 9.
When driving drag chain 2 to carry out stretching or retract action, upper directive wheel 5 and lower directive wheel 6 can be guided and be dragged telescopic arm 1
Chain, which commutates from the extending direction of the first straight-arm 3 to along 1 direction of telescopic arm, to be extended, while when preventing drag chain 2 in telescopic arm 1 from moving
Along perpendicular to extending direction protrusion.Because drag chain 2 by multiple there is straightway and rotatable joint to form, when rolling with it is upper
Not only there is rolling friction that can also exist because of joint motions and upper directive wheel 5 and lower guiding between directive wheel 5 and lower directive wheel 6
Wheel 6 generates slight shock, and upper directive wheel 5 and lower 6 material of directive wheel are yielding rubber, have shock-absorbing functions, is reducing drag chain 2
Abrasion while can amplitude peak reduce the shock between drag chain 2 and upper directive wheel 5 and lower directive wheel 6.
The head of the telescopic arm 1 is provided with workbench 7, also sets between the head and workbench 7 of the telescopic arm 1
It is equipped with leveling hydraulic system 12.When first straight-arm 3 rotates on pedestal, leveling hydraulic system 12 adjusts workbench 7
Keep horizontal.
Such as Fig. 4, pipeline assembly 13 enters inside cantilever crane by 3 tail portion of the first straight-arm；Such as Fig. 3, pipeline assembly 13 passes through folding
Cavity pile warp to 2 tail portion detour of drag chain enters inside drag chain 2 between bent plate 9 and the first straight-arm 3, through 2 inner passage of drag chain from dragging
2 head of chain is stretched out, and can connect the control being mounted at 1 head of telescopic arm or workbench 7 by the pipeline assembly 13 that drag chain 2 comes out
Element or executive component processed.
