Large-scale bearing pin dismounting of above-mentioned crawler crane and conveying arrangement, wherein, described clamp is fixed on the described support by backing pin.
Large-scale bearing pin dismounting of above-mentioned crawler crane and conveying arrangement, wherein, during transportation, bearing pin places a side of close described ring baffle in the described support, and fixes with described baffle plate.
Large-scale bearing pin dismounting of above-mentioned crawler crane and conveying arrangement, wherein, described bearing pin is in the same place by bolting with described baffle plate.
Large-scale bearing pin dismounting of above-mentioned crawler crane and conveying arrangement wherein, during dismounting, are removed the described backing pin of fixing described baffle plate, will draw pin oil cylinder one end to place in the draw-in groove of described clamp, and the other end links to each other with the described pin that draws.
Large-scale bearing pin dismounting of above-mentioned crawler crane and conveying arrangement wherein, during dismounting, by described clamp is fixed on the diverse location of described support, and utilize described the flexible of pin oil cylinder that draw that described bearing pin is carried out the classification dismounting.
Large-scale bearing pin dismounting of above-mentioned crawler crane and conveying arrangement wherein, after dismounting finishes, insert backing pin with fixing described bearing pin on described baffle plate.
Overweight problem when large-scale bearing pin dismounting of crawler crane of the present invention and conveying arrangement have avoided bearing pin to transport with main body, its utilization draws the pin oil cylinder to carry out the classification dismounting, simple in structure, easy to operate, can realize the secure of bearing pin during transportation, safe and reliable, effectively reduce operator's labour intensity and running cost, have higher use value.

The specific embodiment
The present invention will be further described in detail below in conjunction with accompanying drawing.
Large-scale bearing pin dismounting of crawler crane of the present invention and conveying arrangement can be realized the simple dismounting of bearing pin and transportation separately, have effectively alleviated the weight of crane main body, thereby have reduced operator's labour intensity and working time.
Following mask body is introduced the structure of large-scale bearing pin dismounting of this crawler crane and conveying arrangement.Fig. 1-Fig. 3 is the travel position figure of large-scale bearing pin dismounting of crawler crane of the present invention and conveying arrangement.As seen from the figure, this device comprises support 1, and its main body is an arc pallet and two channled rails, so that support bearing pin, makes its firm transportation.One side of support 1 is a U-shaped baffle plate, and opposite side is a ring baffle.Wherein, the diameter of the hollow space of described ring baffle is greater than the diameter of bearing pin, and during with the assurance dismounting, bearing pin can pass above-mentioned hollow space.Four suspension centres are arranged on two channled rails, it is adjusted to the suitable position of crane main body, re-use bolt one end of support 1 is fixed on the crane main body, thereby guarantee its firm transportation.Clamp 2 is fixed in the support 1 by backing pin 5, and it is close on the above-mentioned U type baffle plate.Baffle plate 6 also is fixed on described internal stent by backing pin 5, wherein, draws 3 of pins to be fixed on two channled rails.When travel position, bearing pin 4 is placed on the inside of support 1, and abuts against an end of ring baffle, bearing pin 4 by bolted on baffle plate 6.Because bearing pin 4 is by firm the holding of arc pallet, effectively preventing coming off of bearing pin, thereby guaranteed the general safety transportation of bearing pin 4 in support 1 inside.
Fig. 4-Fig. 5 is large-scale bearing pin dismounting of crawler crane of the present invention and conveying arrangement dismounting state diagram.During the bearing pin dismounting, at first the backing pin 5 with fixed dam 6 takes out, and will draw an end of pin oil cylinder to place in the draw-in groove of clamp 2 then, and the other end links to each other with drawing pin 3.Dismounting along with the flexible realization bearing pin that draws the pin oil cylinder.Wherein, clamp 6 will be along with the Telescopic Fixed diverse location at support 1 that draws the pin oil cylinder, thereby realizes the classification dismounting of bearing pin.The pattern of this classification dismounting has reduced the stroke of oil cylinder, makes whole apparatus structure compactness, has effectively reduced operator's labour intensity.After bearing pin is finished by dismounting, with backing pin 5 that baffle plate 6 is fixing again, thus make bearing pin 4 by secure.
By the way bearing pin is carried out dismounting and transportation, the overweight problem that can avoid bearing pin to occur with the main body transportation.Large-scale bearing pin dismounting of crawler crane of the present invention and conveying arrangement utilization draw the pin oil cylinder to carry out the classification dismounting, and be simple in structure, easy to operate, can realize the secure of bearing pin during transportation, safe and reliable, effectively reduce operator's labour intensity and running cost, have higher use value.
More than specific embodiments of the invention are described in detail, but the present invention is not restricted to specific embodiment described above, it is just as example.To those skilled in the art, any equivalent modifications that the large-scale bearing pin dismounting of this crawler crane and conveying arrangement are carried out and substituting also all among category of the present invention.Therefore, not breaking away from impartial conversion and the modification of having done under the spirit and scope of the present invention, all should contain within the scope of the invention.
