Detailed Description
The invention is further illustrated by the following specific examples in conjunction with the accompanying drawings.
The invention relates to a vertical transportation and hoisting device for an arc-shaped prefabricated part in an oversized-diameter shield tunnel, which is characterized in that the lower part of the arc-shaped part is arc-shaped, so that a steel wire rope, a sling and other hoisting tools cannot be directly used, the size of the arc-shaped part is large, the height of the top is high, and a clamp cannot be directly fixed on the top manually.
As shown in fig. 1 to 4, the vertical transportation and hoisting device for the arc-shaped prefabricated part in the ultra-large diameter shield tunnel comprises the following parts: the lifting lug comprises a lifting lug 1, a main beam 2, a stand column 3, a transverse support I4, a transverse support II 5, a connecting plate 6, a lifting hook 7, a shaft pin 8, a shoe plate 9, a positioning pin 10 and a limiting steel plate 11.
A main frame structure is formed by the main beam 2, the upright post 3, the transverse support I4 and the transverse support II 5, and a hoisting structure of an arc-shaped component is formed by the lifting hook 7, the shaft pin 8, the positioning pin 10 and the limiting steel plate 11 and is also a main working position of the whole lifting appliance. Be connected with pivot 8 between spacing steel sheet 11 and the lifting hook 7, as the axis of rotation, open two spacing holes on the spacing steel sheet 11, open and close through locating pin 10 control lifting hook, be fixed in the spacing hole in below with lifting hook 7 during lifting by crane, make the lifting hook be in the closure state, after the hoist and mount, be fixed in the spacing hole in top with lifting hook 7, make lifting hook 7 be in the state of opening, the arc can freely come in and go out the hoist.
