Problems solved by technology

[0004] (2) Limitations of on-site construction: the binding of steel bars must be carried out after the assembly of the outer mold of the mobile formwork is completed
[0005] (3) In view of the invariance of the assembly steps of the mobile formwork and the invariance of the construction steps, it often takes a lot of manpower, material and financial resources when binding steel bars and assembling and hoisting inner molds and other parts, thus prolonging the construction period and increasing the assembly cost

Abstract

The invention provides an orbital transfer portal crane matched with a movable formwork. The orbital transfer portal crane matched with the movable formwork can run on a box beam and the movable formwork, adapts to two spans, and not only saves lifting cost, but also shortens a construction period. The orbital transfer portal crane matched with the movable formwork comprises a girder which extends along the left and right direction, wherein an electric hoist is arranged below the girder, the left end and the right end of the girder are respectively and fixedly connected with two support leg groups, each support leg group comprises an external support leg and an internal support leg which are arranged in parallel, the external support legs and the internal support legs are all rigid support legs, an external travelling mechanism which can travel along an external rail is installed on each external support leg, and an internal travelling mechanism which can travel along an inner rail is installed on each internal support leg.

Description

technical field [0001] The invention relates to a gantry crane, in particular to a track-changing gantry crane matched with a mobile formwork. Background technique [0002] The mobile formwork is a construction machine with its own formwork, which uses the cap or pier column as a support to pour the bridge on site. At present, mobile formwork is used as a construction machine for on-site pouring. In view of the characteristics of the current cast-in-place project, the construction steps of mobile formwork are: assembly, positioning, mold closing, binding steel bars, installing inner formwork, binding upper steel bars, and pouring. Traditional gantry cranes can only walk on the ground or on the box girder, and only operate at one span. [0003] The introduction to the existing technology should include three aspects: (1) Assembling and construction of the existing mobile formwork, due to the structure of the steel structure itself and the manufacturing process, the mobil...
