Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bridge installation, and particularly relates to a tool lifting frame for hoisting large structures. Background Technique
[0002] The width of the Yulin River at the bridge site is 137 meters. The height of the main beam directly above the Yulin River from the water surface is about 46 meters, and the height of the highest point of the arch rib from the water surface is about 109 meters. The maximum designed weight of the main beam segment directly above the Yulin River is 50.8 tons, and the heaviest arch rib is 43.1 tons. In order to protect the bridge main beam and be consistent with the designed force calculation model, the design principle requires that the arch rib be hoisted first, and then the main beam be hoisted, and the tensioning starts under the condition that the main beam is not stressed. Due to the too high hoisting height and large weight of the arch rib, using an extra-large crane not only incurs high crane costs, but also the trestle has to bear the ballast under the hoisting condition of the extra-large crane. Fabricating such a trestle is time-consuming and laborious, and the cost is even greater. Therefore, conventional hoisting cannot be completed. Content of the Utility Model

Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.
[0027] The embodiment of the present utility model provides a tool lifting frame for hoisting large structures, as Figure 1-10As shown in the figure, the tooling lifting frame for large-scale structure hoisting includes: a mounting frame 1; a set of lifting components symmetrically and fixedly mounted on the mounting frame 1 for lifting the arch rib; the lifting components include three lifting frame bodies 2, a cross beam 3 and four hydraulic jacks 4, and the lifting frame bodies 2 play a supporting role during the process of lifting the arch rib; the cross beam 3 is fixedly mounted on the tops of the three lifting frame bodies 2, and the cross beam 3 is used for mounting the hydraulic jacks 4; the four hydraulic lifting jacks 4 are fixedly mounted on the top of the cross beam 3, and lifting ropes are arranged on the hydraulic lifting jacks 4, and the lifting ropes are used for hoisting and lifting the arch rib.
[0028] It should be noted that there are a total of 6 lifting frame bodies 2 at the top of the mounting frame 1, and there is a cross beam 3 at the top of 3 lifting frame bodies 2. In order to protect the main bridge girder and be consistent with the designed force calculation model, the design principle requires that the arch rib be hoisted first and then the main girder be hoisted, and the tensioning starts under the condition that the main girder is not stressed. Since the hoisting height of the arch rib is too high and the weight is not small, using an extra-large crane not only incurs high crane costs, but also the trestle has to bear the ballast under the hoisting condition of the extra-large crane. Making such a trestle is time-consuming and laborious, and the cost is even huge. Therefore, conventional hoisting cannot be completed;
[0029] In this embodiment, at the position where the lifting frame body 2 is installed, steel pipes of 630×10 are first driven into the Yulin River. The length of the steel pipe is about 34 meters, of which the depth of the driven pile into the rock is not less than 10 meters, and it is poured with concrete with a height not less than 5 meters, thus forming a pile foundation 5.

When using multiple lifting frame bodies 2 to hoist the arch rib, the lifting ropes on the multiple hydraulic lifting jacks 4 are connected to the arch rib, and the lifting ropes are lifted by the hydraulic lifting jacks 4, thereby driving the arch rib to be lifted. When the arch rib is lifted to the corresponding position, finally the construction workers can adjust and weld at high altitude. Through the entire tooling lifting frame, the arch rib can be lifted, which is more convenient compared with the traditional crane hoisting method.
