Movable bailey truss hanging basket

Abstract

The invention provides a movable bailey truss hanging basket. The movable bailey truss hanging basket comprises bailey truss longitudinal beams, bailey truss cross beams and a hoisting mechanism, Thebailey truss longitudinal beam extends in the longitudinal bridge direction, the bailey truss cross beam extends in the transverse bridge direction and is located above the bailey truss longitudinal beam, the hoisting mechanism is arranged on the bailey truss cross beam, and a cross beam moving rail extending in the length direction of the bailey truss longitudinal beam is arranged between the bailey truss longitudinal beam and the bailey truss cross beam. The bailey truss cross beam drives the hoisting mechanism to move along the bailey truss longitudinal beam through the cross beam moving rail; longitudinal beam moving rails extending in the length direction of the bailey truss longitudinal beam are arranged at the bottom of the bailey truss longitudinal beam, and a plurality of sets ofrear anchoring mechanisms anchored to bridge block segments are arranged on the bailey truss longitudinal beam and sequentially connected with the continuous bridge block segments. According to the movable bailey truss hanging basket, a standard bailey truss is adopted as a main bearing structure, the structure stress is good, construction is convenient, and the construction efficiency is high.

Description

technical field [0001] The application relates to the technical field of bridge demolition operations, in particular to a mobile Bailey frame hanging basket. Background technique [0002] The demolition of old bridges generally follows the reverse process of new bridge construction. For the variable cross-section continuous girder bridges built with hanging baskets, the most commonly used demolition method is to use hanging baskets to carry out block hoisting and demolition or large-scale hoisting The equipment is directly hoisted and demolished in blocks. Since the cross-channel variable cross-section continuous girder bridge spans the existing traffic channel underneath, its dismantling process has a great impact on the traffic of the channel. It is often carried out by lowering and dismantling the hanging basket. [0003] At present, the existing equipment for removing hanging baskets from old bridges is diamond-shaped hanging basket removal and lowering equipment. The p...

Problems solved by technology

In addition, in the dismantling of the diamond-shaped hanging basket equipment in the continuous beam bridge with variable cross-section across the waterway, it takes a long time due to the need to carry out the anchoring of the rear anchor equipment and the overall longitudinal movement of the hanging basket equipment during the closed navigation period. In general, the closure time given by the waterway department is generally short. If the scheduled construction task cannot be completed within the specified time, it generally needs to be postponed until the next closure period. Multiple closures will lead to a longer overall construction period. Long, and have a greater impact on the passage of the channel
