Embodiment Construction

[0032] The hoisting crane with large lifting capacity and large lifting height provided by the present invention has a structure such as figure 1 , figure 2 , image 3 As shown: it includes a four-tower leg portal frame, a trolley 7, two sets of hoisting mechanisms 12, two sets of trolley traction mechanisms 6 and multiple sets of buttress supports 2. Two sets of hoisting mechanisms 12 are symmetrically arranged on the trolley 7. Under the traction of the two sets of trolley traction mechanisms 6, the trolley 7 can walk on the track of the main beam 5 of the four-tower leg portal frame. The two sets of trolley traction mechanisms 6 Symmetrically arranged on the beam 11 at one end of the portal frame of the four tower legs, the buttress 2 is used to connect the four tower legs 1 and the installed building 3 to increase the strength, rigidity and stability of the tower legs 1.

[0033] Such as figure 1 , figure 2 , image 3 Shown: the four-tower-leg portal frame is made u...

Abstract

The invention relates to a hoisting crane with large lifting load and lifting height, which comprises a four tower leg portal frame, a trolley (7), two sets of trolley traction mechanisms(6) and a hoisting mechanism (12), wherein the four tower leg portal frame consists of four tower legs (1) and a frame supported by the tower legs, and the frame consists of two main beams (5) and cross beams (11); the top of each tower leg is matched with a jacking mechanism and a jacking stock (4) of a tower crane capable of adjusting the height of the tower legs; the two main beams (5) are all paved with tracks for a trolley to travel; and sustaining wall supports (2) are arranged between the four tower legs and the mounted buildings(3). The hoisting method of the crane comprises: mounting and debugging the crane; repeatedly and simultaneously adjusting the height of the four tower legs and gradually hoisting steel structure sections according to requirements, and disassembling the crane. The tower legs have the advantages of lifting function, as well as convenient assembly and disassembly, and the hoisting machine is suitable for large lifting load and lifting height hoisting steel structure buildings.

Description

technical field [0001] The invention relates to the field of hoisting equipment, in particular to a hoisting crane with a large lifting capacity and a large lifting height. Background technique [0002] In modern engineering construction, some super-height steel structure tower buildings are being used more and more, such as steel structure tower columns and TV towers of some long-span suspension bridges or cable-stayed bridges, the height of these tower buildings It can reach more than 200m and is composed of several sections of steel structural parts spliced ​​end to end. Usually, in order to ensure the rationality of the structure and the overall aesthetics, it is required to reduce the number of spliced ​​joints as much as possible, that is, to reduce the number of segments of steel structural parts. As a result, the maximum mass of a single-section steel structure may exceed 500 tons, and the section with the maximum mass may appear at the top. Therefore, when hoisting ...
