Movable hanging basket device for tied-arch bridge concrete tie bar

Abstract

The invention relates to a movable hanging basket device for a tied-arch bridge concrete tie bar, and belongs to the field of bridge construction equipment. The device comprises a working platform, awalking support and a plurality of rollers. The walking support comprises a first vertical rod, a second vertical rod, a first transverse rod and a second transverse rod. The first vertical rod is arranged on one side surface of the tie bar; one end of the first vertical rod is fixedly connected with the working platform, the first transverse rod and the second transverse rod are both located on the side surface, close to a hanging bar, of the tie bar, one end of the first transverse rod is fixedly connected with one end of the first vertical rod, the other end of the first transverse rod is hinged to the second transverse rod, and a hinged point of the first transverse rod and the second transverse rod is positioned on one side of the hanging bar; and the other end of the second transverse rod is connected with the second vertical rod, and the second vertical rod is arranged on one side surface of the tie bar. The hanging basket device has the effects that the hanging basket device can be moved conveniently, through the hanging bar, the moving range of the hanging basket device is wider, and construction is more convenient.

Description

technical field [0001] The present application relates to the field of bridge construction equipment, in particular to a movable hanging basket device used on concrete tie rods of a tied arch bridge. Background technique [0002] Tied arch bridge is a bridge type that combines the advantages of arch and beam. It combines the two basic structural forms of arch and beam to bear the load together, and give full play to the structural performance and combination of beam bending and arch compression. effect. Tie rods and suspenders are one of the important components of a tied arch bridge. The tie rods that bear the horizontal thrust of the arch end are called tie rods in the tie arch bridge, which prevent the support at the arch end from generating horizontal thrust and become a thrustless arch. Suspenders are generally long and slender members, which are usually considered as axially stressed members in design to enhance the stability of arch ribs. [0003] When carrying out ...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that during the construction of the tie-bar arch bridge, the suspenders are usually fixed on the upper surface of the tie-bars. The movement of the hanging basket device is hindered, making it difficult for the hanging basket device to move to the place to be constructed
