The invention discloses an inverted lifting device for installation of a separated suspension bridge steel beam and a construction method thereof, the inverted lifting device comprises a plurality of inverted lifting devices, and any inverted lifting device comprises a coiling device; the lifting frame is connected with the winding device and comprises a steel strand jack; the anchor head seat and the lifting frame are arranged at intervals in the vertical direction, one end of each steel strand is fixed to the winding device, the other end of each steel strand penetrates through the lifting frame and then is fixed to the anchor head seat, and the winding device, the lifting frame and the anchor head seat jointly form a lifting system; and the beam top connecting device and the beam bottom connecting device are connected with the lifting system, the suspension bridge upper structure and the to-be-mounted steel beam correspondingly. The lifting systems, the beam top connecting devices, the beam bottom connecting devices and the like in the multiple inverted lifting devices are of a separated structure, different combination modes can be adopted for steel beam installation according to the actual construction condition, the limitation on the lifting height is reduced under the condition that the installation stability is guaranteed, and the construction efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of bridge construction. More specifically, the present invention relates to an inverted lifting device for steel girder installation of a detached suspension bridge and a construction method thereof. Background technique [0002] Among various bridge structures, the suspension bridge is currently the bridge type with the strongest spanning capacity. The main girder of the suspension bridge usually includes two structural forms: steel box girder and truss type. The most common method of installing the main girder is the installation of the cable crane, followed by the installation of the floating or cable crane. When using a cable-mounted crane or a cable crane for installation, the design cycle is longer and the cost is higher; while when using a floating crane for hoisting, it is necessary to completely seal the navigation channel or reserve a navigation hole, which affects the normal navigation of the cha...
