Assembly type buoy-powered mast-combined crane device and hoisting method thereof

Abstract

The invention discloses an assembly type buoy-powered mast-combined crane device. The device comprises a float system, a hoisting system and a mast amplitude variation system, wherein a supporting platform is anchored on the float system, and the hoisting system and the mast amplitude variation system are arranged on the supporting platform; the mast amplitude variation system comprises an amplitude variation winch, first masts, second masts, third masts and an amplitude variation steel wire rope, the first masts, the second masts and the third masts are sequentially hinged, a steel box is fixedly connected between upper ends of the two third masts, and the amplitude variation winch is connected with the upper ends of the third masts through the amplitude variation steel wire rope; the hoisting system comprises a hoisting winch, a hoisting steel wire rope and a hook, and the hoisting winch controls the hoisting steel wire rope to pull a heavy object. The whole device is supported by the float system, a proper hoisting point can be found through the mast amplitude variation system, and finally, the heavy object is hoisted by the hoisting system; the device has the advantages that the device is simple to assemble and fast and convenient to use, and the construction cost can be saved.

Description

technical field [0001] The invention relates to the technical field of hoisting, in particular to an assembled power buoy combined mast crane device and a hoisting method thereof. Background technique [0002] At present, during the construction of cable-stayed bridges, due to the construction in water, many hoisting methods that are convenient to implement on land often fail to work in water. At present, the construction in water generally uses the method of hoisting boats or floating cranes with huge equipment, which is not easy Operation, and the hoisting vessel used is often leased, and the lease fee is too high. Contents of the invention [0003] The invention provides an assembled power buoy combined mast crane device with simple assembly and quick operation and a hoisting method thereof. [0004] To achieve the above object, the technical solution of the present invention is: [0005] An assembled power buoy combined mast crane device, including a buoy system, a h...
