Movable safe operation platform device for large-span steel bridge deck construction

Abstract

The invention discloses a movable safe operation platform device for large-span steel bridge deck construction. The movable safe operation platform device comprises main longitudinal beam steel pipes, brackets, walking structure track beams, walking tracks, walking mechanisms, track fixing devices, operation platform main longitudinal rods and locking assemblies. The device stretches across the whole bridge floor and can move like a gantry crane, operators can conveniently conduct construction at all positions at any time, and convenience is achieved; the operation platform can be limited to the track on the track through the quite convenient track fixing device, the platform is lifted by rotating the screw rod when the operation platform is static, the platform braking effect is achieved, the locking assembly is cooperated, positioning of the operating platform can be more stable, the working stability of the operating platform is improved, smooth construction is guaranteed, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a mobile safe operation platform device for large-span steel bridge deck construction. Background technique [0002] With the rapid development of the social economy and the increasingly mature bridge construction technology, the long-span bridges across the river and across the river have gradually received attention and praise; due to the large span of the bridge, the conventional operating platform cannot be processed in the design structure and construction process of the bridge. The installation and other conditions match and cannot meet the construction needs. The traditional method is to use a fixed hanging basket or a fixed inspection platform. On the one hand, this method cannot provide a safe and comfortable operating environment. On the other hand, the hanging basket and the inspection platform are The fixed type cannot be moved at any time during construct...

[0002] With the rapid development of the social economy and the increasingly mature bridge construction technology, the long-span bridges across the river and across the river have gradually received attention and praise; due to the large span of the bridge, the conventional operating platform cannot be processed in the design structure and construction process of the bridge. The installation and other conditions match and cannot meet the construction needs. The traditional method is to use a fixed hanging basket or a fixed inspection platform. On the one hand, this method cannot provide a safe and comfortable operating environment. On the other hand, the hanging basket and the inspection platform are Fixed, cannot be moved at any time during construction, lacks construction efficiency and convenience, and has a large construction safety hazard
