Embodiment Construction
[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments, and the mode of the present invention includes but not limited to the following embodiments.
[0028] Such as Figure 1-4 As shown, a method for turning over and hoisting a large-scale 7-shaped truss structure provided by the present invention includes the following steps:
[0029] Step 1, lifting and turning over the 7-shaped truss structure 1, using three cranes to turn over, among the three cranes, one is the main crane 7, and the other two are respectively the first auxiliary crane and the second auxiliary crane;
[0030] First of all, four hanging points are set in the middle of the upper edge of the 7-shaped truss structure 1. Among the four hanging points, one of the hanging points is connected to a fixed hanging rope 21, and the remaining three hanging points are connected to a hand-drawn rope respectively. hoist 22, the free ends of the fixed slin...

The invention discloses a large 7-shaped truss structure turn-over lifting method, and solves the problems that lifting efficiency is low, a 7-shaped truss structure is large in deformation in the lifting process, and ground assembly sections are more when the 7-shaped truss structure is lifted in the prior art. The method includes the steps: 1 lifting and turning over the 7-shaped truss structureby 90 degrees; 2 adjusting the position of the 7-shaped truss structure to be consistent with working conditions in erecting and setting; 3 lifting the 7-shaped truss structure to an erecting position and fixedly welding the 7-shaped truss structure to finish lifting. The lifting process is smooth, simple and standard, the lifting efficiency of the large 7-shaped truss structure can be effectively improved, the ground assembly sections and the deformation of the 7-shaped truss structure are decreased, and overall safety and effective lifting of the 7-shaped truss structure are ensured.
Description
technical field [0001] The invention relates to a method for turning over and hoisting a large 7-shaped truss structure. Background technique [0002] The large-scale 7-shaped truss structure is large in size and heavy, and the hoisting efficiency of the existing technology is low. During the hoisting process, there are many ground assembly sections and large deformation, which brings trouble to the hoisting. Therefore, a large-scale 7-shaped truss structure is designed. Turning over the hoisting method to improve the hoisting efficiency, reduce the deformation of the large-scale 7-shaped truss structure in the hoisting process, and the ground assembly section have become technical problems to be solved urgently by technicians in the technical field. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for turning over and hoisting a large 7-shaped truss structure, which solves the low hoisting efficiency of ...
