Abstract

The invention relates to a movable supporting device for river-crossing bridge construction, and belongs to the field of bridge construction equipment.The movable supporting device comprises a ship body and a supporting set frame fixed to a deck of the ship body, a main distribution supporting assembly is arranged between the supporting set frame and the ship body, and the supporting set frame is fixed to the main distribution supporting assembly; the main distribution supporting assembly comprises a plurality of longitudinal distribution beams and transverse distribution beams, the longitudinal distribution beams are arranged in parallel and fixedly connected with the ship body, the transverse distribution beams are located on the sides, away from the ship body, of the longitudinal distribution beams, and the transverse distribution beams are perpendicularly and fixedly connected with the longitudinal distribution beams. The supporting device has the effects of reinforcing the ship body, enabling the structure of the ship body to be more stable and better providing supporting, floating towing loads can be evenly transmitted to the ship body, the safety of the ship body is guaranteed, stress on the ship body is more uniform, and supporting is better provided for a bridge structure.

Description

technical field [0001] The present application relates to the field of bridge construction equipment, in particular to a mobile supporting device for bridge construction across rivers. Background technique [0002] As an emerging technology for bridge erection construction, floating towing technology is widely used in the erection construction of tie-bar arch bridges, steel truss bridges and other assembleable structures across rivers, effectively solving the problem of not allowing temporary supports to be erected in rivers and obstructing traffic. , Short flight closure time and other problems. This technology requires the establishment of a mobile support device on water as the front fulcrum of the bridge structure floating tow. Commonly used mobile support devices on water include barges and temporary support frames installed on the barges for supporting bridge structures. [0003] The relevant publication number is the Chinese invention patent of CN109797663A, which d...
