Abstract

The invention relates to the field of hydraulic trestles, in particular to a stepping hydraulic trestle for large-span inverted arch construction. According to the technical scheme, the technical problems that the lifting function of a traditional hydraulic trestle is not convenient to adjust, and the width of a trestle body is not convenient to adjust are solved. The device comprises a supporting adjusting structure, a bottom plate connecting frame, a supporting seat plate, a stand column frame rod and a supporting bridge plate, the side end of the supporting adjusting structure is fixedly connected with the bottom plate connecting frame, the upper end of the bottom plate connecting frame is fixedly connected with the supporting seat plate, and the upper end of the supporting seat plate is fixedly connected with the stand column frame rod; a supporting bridge plate is fixedly connected to the upper end of the stand column frame rod, and the supporting adjusting structure comprises an adjusting component, a limiting plate frame, a side supporting plate frame, a supporting rack and a supporting bottom frame plate. The technical scheme has the beneficial effects that through combined connection of the structures, the lifting function can be conveniently adjusted, meanwhile, the width of the bridge body can be conveniently adjusted, and overall adjustment and control work can be conveniently carried out.

Description

technical field [0001] The invention relates to the field of hydraulic trestles, in particular to a large-span inverted arch construction stepping hydraulic trestle. Background technique [0002] The promotion of movable inverted trestle bridges has solved the problem that the excavation and support construction of the tunnel face and the construction of the inverted arches on traditional trestle bridges cannot be carried out at the same time (tooling and materials for the construction of the tunnel face can pass through the upper part of the trestle bridge, and the construction of the lower part It is not affected, and provides a comfortable and spacious environment for the construction personnel at the lower part of the trestle); at the same time, the labor input has been reduced by half, and the production efficiency of construction has increased by 30%. It is convenient to adjust the lifting work, but it is inconvenient to carry out adaptive adjustment control, and it is...
