Abstract

The invention discloses a hoisting device and a hoisting method used for aerial posture adjusting and positioning of a steel box arch rib. The hoisting device comprises an adjustable hoisting belt mechanism, sling mechanisms and a hoisting rack mechanism, wherein the adjustable hoisting belt mechanism comprises hoisting belts with adjustable lengths and shackles; the lower end of each hoisting belt is connected with the corresponding shackle, and is connected with the hoisting rack mechanism through the shackle; 1-5 groups of jacks are parallelly arranged on the upper surface of the hoisting rack mechanism; each group of jacks comprises 1-10 jacks which are arranged at intervals; each jack is connected with a steel strand; the lower end of each steel strand penetrates through the lower surface of the hoisting rack mechanism, and is connected with the corresponding sling mechanism; and the lower end of each sling mechanism is provided with a rotary shaft which is connected with a hoisting lug of the steel box arch rib. Aerial posture adjusting of the steel box arch rib can be performed by adjusting the lifting height of the jacks and the rotation angles of the rotary shafts; the lifting height and horizontal inclination angle of the steel box arch rib can be integrally controlled through the hoisting device and the hoisting method; and vertical inclination angle control can be realized by separately adjusting a single hoisting point.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a hoisting device and a hoisting method for attitude adjustment and positioning of steel box arch ribs in the air. Background technique [0002] At present, during the installation and construction of steel box arch ribs of long-span steel box arch bridges, since the steel box arch ribs are affected by temperature changes and various equipment manufacturing errors, necessary, Effective measures are to locate it accurately, adjust its attitude in the air, and ensure that the parameters such as the axis of the arch and the deviation of the ring seam of the arch rib of the steel box meet the relevant specifications. [0003] For the steel box arch ribs of the long-span basket steel box arch bridge, it is particularly difficult to ensure the precise positioning of its attitude in the air. [0004] The patent No. 200810148104.1 of the invention patent "Adjustment method for segment...
