Combined-type hanging basket with full-rotation crane and construction method of combined-type hanging basket

Abstract

The invention discloses a combined-type hanging basket with a full-rotation crane. The combined-type hanging basket comprises a hanging basket system and the rotation crane. The hanging basket systemcomprises a track beam and a hanging basket body, and a slipping mechanism matched with the track beam is fixed to the bottom of the hanging basket body. A walking moving mechanism capable of drivingthe slipping mechanism to move is arranged on the track beam, and the rotation crane is fixed to the top of the hanging basket body. According to the combined-type hanging basket, two structure typesof the rotation crane and the hanging basket body are innovatively combined, two technologies of beam body cast-in-place and corrugated web hoisting are effectively combined, and the great applicationvalue is achieved on corrugated web bridge construction; a combined structure of the rotation crane and the hanging basket body longitudinally slips through the walking moving mechanism, and the demand of the construction technology is met; and a combined hoisting machine is mounted on the beam section top face, then a beam body template, a steal bar and a corrugated web of the next section can be hoisted and erected directly, the requirement for the environment is low, the construction speed is high, construction is safe and convenient, the construction efficiency is high, tedious mounting operation of a large hoisting device is omitted, the turnover use efficiency is high, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of bridge construction equipment, in particular to a combined hanging basket with a full-turn crane and a construction method thereof. Background technique [0002] In the existing bridge construction, the main span girders are mostly located in inconvenient places such as water or canyons. The bridge girders are usually manufactured in a factory, transported to the construction site, and then used for large-scale erection such as girder cranes or floating cranes. Lifting equipment for lifting. However, steel-concrete structure bridges, especially steel-concrete structure cast-in-place beams with corrugated webs, include the cast-in-place concrete part and the hoisting part of corrugated webs, and the operation is complicated. The concrete part is usually cast-in-place with hanging basket cantilever, and the corrugated web is usually hoisted with gourd crane or temporary support. The two materials cannot be...

Problems solved by technology

However, steel-concrete structure bridges, especially steel-concrete structure cast-in-place beams with corrugated webs, include concrete cast-in-place parts and corrugated web hoisting parts, and the operation is complicated.

The concrete part is usually cast-in-place with hanging basket cantilever, and the corrugated web is usually hoisted with gourd crane or temporary support. The two materials cannot be constructed with the same equipment, and there are waiting and differences in the process of hanging basket cantilever cast-in-place and temporary support hoisting. Continuous, cannot be well combined, the measures are cumbersome, the installation and construction efficiency is low, and there are certain construction safety risks in the hoisting of temporary supports, and the degree of automation is not high

At present, the construction of steel-concrete structure bridges with corrugated webs in my country is still in an immature stage, and there is a certain distance from the international technical level, which brings great limitations to the construction
