Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] A hanging basket assembly shifting device as shown in the figure, it includes two main beams 1 connected as a whole, the main beams 1 are made of I-shaped steel beams, the bottom surface of the main beams 1 is provided with forward moving rollers 5, and the main beams The top surface of 1 is provided with a traversing trolley and a bracket, the traversing trolley is slidably connected to the top surface of the main beam 1, and the bracket is fixed on the top surface of the main beam 1.

[0026] In this example:

[0027] The main girders 1 are connected by staggered scissor braces 2, and there is a truss-type connecting beam 3 between the corresponding connection points of the scissor braces 2 and the main girder 1, and the scissor braces 2 and the truss-type connecting beam 3 connect the two main girders 1 into one.

Abstract

The invention discloses a device for shifting hanging basket assembly pieces and a construction method. The device comprises two main beams connected into a whole. Forwards-shifting idler wheels are arranged on the bottom faces of the main beams. A transversely-shifting trolley and a bracket are arranged on the top face of each main beam, the transversely-shifting trolleys are in sliding connection with the top faces of the main beams, and the brackets are fixed on the top faces of the main beams. According to the device, the transversely-shifting trolleys and forwards-shifting devices (the forwards-shifting idler wheels) are used, a heavy main longitudinal beam front section of a hanging basket can be lifted through a first tower crane with high lifting capacity, a light front transverse beam of the hanging basket is lifted through a second tower crane with low lifting capacity, therefore, the requirements for the lifting capacity of the tower cranes when the hanging basket is assembled can be greatly reduced, the use cost of the tower cranes is greatly reduced, and the hanging basket assembly efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of assembly and construction of hanging baskets of cable-stayed bridges, in particular to a device for shifting a hanging basket assembly and a construction method. Background technique [0002] In the assembly construction of overweight hanging baskets on cable-stayed bridges, the conventional assembly method is to install a large tower crane on the top of the left and right towers, and use the tower crane to hoist each beam and longitudinal beam of the hanging basket to the assembly bracket of the hanging basket one by one to assemble into a "field" Shaped hanging basket. Due to the different weights of each crossbeam and longitudinal beam in this assembly construction method, tower cranes need to be configured according to the crossbeams and longitudinal beams of different weights, resulting in high cost, low equipment utilization rate and low construction efficiency. [0003] Therefore, prior art needs ...
