Underbridge work platform system

Abstract

The invention discloses an underbridge work platform system. The underbridge work platform system is composed of a folding arm anti-flexural tensioning mechanism (1), an obstacle-passing mechanism (2), a lifting mechanism (3), a rotating mechanism (4), an anti-tipping device (5) and a walking mechanism (6); and the underbridge work platform system is characterized in that the upper end of the folding arm anti-flexural tensioning mechanism (1) is inserted into the rotating mechanism (4), the lifting mechanism (3) is installed on the rotating mechanism (4), the rotating mechanism (4) is connected with the walking mechanism (6), the rotating mechanism (4) and the walking mechanism (6) are connected with the anti-tipping device (5), and the obstacle-passing mechanism (2) is installed on the walking mechanism (6). According to the underbridge work platform system, assembling is rapid, safety and reliability are achieved, the construction is easy to operate, the cost is low, the rate of progress is high, tipping does not occur, bridge surface self-walking is realized, and the underbridge work platform system can pass obstacles of a lamp pole and a sign pole conveniently and rapidly.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to an under-bridge operating platform system. Background technique [0002] Along with the national strategic development plan and the needs of regional infrastructure development, expressways and high-grade highways gradually cover steep mountainous areas and crowded dense cities, which promotes the construction and development of viaducts. [0003] Simply supported continuous beams are often used in the construction of viaducts, and the bridge deck is narrow in construction. At the same time, due to the constraints of the terrain, the traditional construction methods have great limitations: First, the process requirements are high, and the beams must be hoisted in place and cast in place. Sequential construction of wet joints and middle (end) beams, tensioning, grouting, bridge deck pavement and ancillary works; second, the working face is small, difficult ...

AI Technical Summary

Problems solved by technology

[0006] Existing under-bridge construction generally adopts floor-to-ceiling steel frame platforms, construction hanging baskets, lift vehicles, bridge inspection vehicles, etc. to carry out inspection and maintenance work: bridge inspection vehicles are expensive, with small load capacity, and elevator vehicles and floor-to-ceiling steel frame platforms are limited For high bridge pier operations, the construction hanging basket is bulky, difficult to transport, and poorly adaptable to height and width, causing great safety hazards
