Trackless type triangle hanging basket

Abstract

The invention discloses a trackless type triangle hanging basket. The trackless type triangle hanging basket comprises a main truss system, a reverse hanging system, a supporting system (8) and a bottom basket system. The reverse hanging system, the supporting system (8) and the bottom basket system are installed on the lower portion of the main truss system. The trackless type triangle hanging basket is characterized in that the main truss system comprises two triangular main trusses (1) disposed at two ends of a lateral connecting truss (2) and a front upper cross beam (7) at the front end,and each triangular main truss (1) includes a stand column (26), a main longitudinal beam (13) and back anchors (9); the stand columns (26) are detachably supported on the main longitudinal beams (13), and the two ends of cable-stayed steel belts (11) are separately connected to the tops of the stand columns (26) and the end portions of the main longitudinal beams (13) in a relatively rotating mode; and the main longitudinal beams (13), the stand columns (26) and the cable-stayed steel belts (11) form a triangle, and the back anchors (9) are fixedly arranged on the tail portions of the main longitudinal beams (13). The trackless type triangle hanging basket is convenient to walk, safe and efficient, simple in structure and convenient to assemble and disassemble, and is suitable for the popularization and use of the construction of a suspending cast box beam by the trackless triangle hanging basket.

Description

technical field [0001] The invention belongs to the technical field of bridge construction devices, and in particular relates to a trackless triangular hanging basket. Background technique [0002] The reinforced concrete cantilevered box girder bridge is one of the most suitable, reasonable and economical bridge types in mountainous areas. Especially in the western mountainous areas where the height difference is large, it is very necessary to build reinforced concrete cantilevered box girder bridges. In view of the more complex topographic and geological conditions and the harsher transportation environment for the highway bridges in mountainous areas, the construction of reinforced concrete cantilevered box girder bridges in mountainous areas puts forward new requirements in terms of structural design and construction technology: a. Construction materials and equipment should be transported as much as possible Possibly convenient; b. no need for prefabricated sites; c. si...

AI Technical Summary

Problems solved by technology

The conventional track-type hanging basket must ensure that the anchoring of the walking track is carried out step by step at any time, and the track is usually two I32a I-beams, which are heavy in weight. When it exceeds the working range of the tower crane, it is very difficult to manually drag the track. The proficiency and sense of responsibility of workers are uneven, and the conventional track-type hanging basket has a large walking safety risk

The above many problems lead to the existing hanging basket mechanism can no longer meet the demand
