Description

A walking device for a bridge hanging basket

technical field

The utility model relates to the field of bridge hanging basket construction equipment, in particular to a walking device for a bridge hanging basket.

Background technique

At present, most of the domestic prestressed concrete continuous beams or continuous steel structures are constructed with pre-point hanging baskets. The hanging basket is the main equipment for cantilever pouring construction. The hanging basket is a load-bearing structure that can slide or roll along the top of the beam. It is anchored and suspended on the front end beam section that has been constructed. On the hanging basket, the formwork, steel bars, and prestressed pipes of the next beam section are installed, concrete grouting and After the prestressed tensioning and grouting operations complete a stage cycle, the hanging basket is moved forward and fixed, and the cantilever grouting of the next section is performed, and the cycle is completed until the cantilever grouting is completed.

During the construction process, after the section tensioning is completed, the hanging basket needs to be moved forward, so a traction hanging basket needs to be used to move forward. At present, the domestic hanging basket is mainly moved forward by manually pulling the chain hoist to move the hanging basket forward. The method of manually pulling the chain hoist to pull the hanging basket forward is to pre-bury the pull ring on the front end of the poured block, and one end of the chain hoist Hang on the pull ring, and the other end hangs on the pull ring welded on the hanging basket, and the hanging basket is pulled forward by manually pulling the chain hoist.

When the main truss of the traction basket moves forward on the rail of the hanging basket, because the main truss of the hanging basket is in direct contact with the rail of the hanging basket, when the main truss of the hanging basket moves forward, the main truss of the hanging basket and the rail of the hanging basket slide relative to each other, and the hanging basket The main truss and the hanging basket track will generate huge friction, and it will take a lot of manpower and material resources to complete the entire moving process.
