Rail-free type walking hanging basket

Abstract

A rail-free type walking hanging basket comprises main trusses and a set of hanging basket main truss, each main truss is formed by a main longitudinal girder, uprights, a front triangular cable stayed steel belt and a rear triangular cable stayed steel belt, the hanging basket main truss is formed by the two main trusses. An upper transverse beam, a front hanging belt, a rear hanging belt, a bottom platform transverse beam and a bottom platform longitudinal beam are arranged at the front end of each main truss. The rail-free type walking hanging basket is characterized in that the main longitudinal girders of the two main trusses are steel box main longitudinal girders with a sliding rail function, main truss propelling supporting points are arranged on the bottom edges of the steel box main longitudinal girders, a front walking trolley with an upper rolling wheel and a lower rolling wheel is arranged on the front sections of the bottom edges of the steel box main longitudinal girders, a main truss propelling rod is horizontally arranged in the center of the front walking trolley, a rear walking trolley with reverse-hanging rolling wheels is arranged at the rear ends of the bottom edges of the steel box main longitudinal girders, and rear anchor transverse beams and anchor rods are arranged on rear end sockets of the steel box main longitudinal girders. The rail-free type walking hanging basket has the advantages that the hanging basket is simple in structure and convenient to mount and demount, and simplifies operation and walking steps, on-site constructors are reduced, and engineering cost is lowered.

Description

technical field [0001] The invention relates to bridge cantilever cast-in-place construction equipment, in particular to a trackless walking hanging basket. Background technique [0002] In the bridge cantilever cast-in-place construction equipment, the traditional construction hangers mainly include diamond hangers and triangle hangers. The upper structures of the two are only different from the rhombus and triangle stress structures. On the reinforced concrete in the pouring section, two I-steel rails are balanced and anchored, and the rolling wheels set at the bottom of the hanging blue are buckled in the I-steel rails and move forward within the length of the I-steel rails. After the pouring of a section is completed, it is necessary to use many jacks to completely jack up the whole hanging basket, and then first remove the anchors of the two I-beam rails on the reinforced concrete, and push it forward to the next section that needs to be poured position, after anchorin...

AI Technical Summary

Problems solved by technology

[0003] This kind of traditional hanging basket not only has a complex structure and uses a lot of steel materials, but also the installation, dismantling, and walking process are very cumbersome, the transportation cost is also higher, and a lot of labor will be invested in the use process. , is not conducive to cost control, and is the bridge cantilever cast-in-place construction equipment that bridge construction units are eager to eliminate
