Description

Technical Field

[0001] This utility model relates to the field of overpass construction, and in particular to a mobile overpass construction and maintenance operation platform frame. Background Technology

[0002] Due to the unique structure and location of pedestrian bridges, mobile, electrically powered climbing suspension platforms are typically used during construction and maintenance to provide standing space for workers. Traditional electrically powered climbing suspension platforms are based on the suspended platform principle, suspending the platform below the bridge structure via steel cables and winches on both sides. Such platforms not only have the problem of difficulty in ensuring consistent suspension height on both sides, but their suspension method is also susceptible to swaying in strong winds. Furthermore, their integrated structure makes it difficult to bypass the obstruction of bridge piers, significantly reducing work efficiency. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a mobile overpass construction and maintenance operation platform frame, which has the advantages of stable structure, convenient movement and recyclability.

[0004] This utility model provides a movable overpass construction and maintenance operation platform frame, including a base, a suspension beam and a suspension platform. The bottom of the base is provided with multiple moving wheels. The suspension beam is detachably installed above the base and its length is greater than the length of the overpass body. The suspension platform includes a standing surface and a connecting beam perpendicularly connected to the standing surface. Two suspension platforms are arranged facing each other on the left and right sides of the suspension beam and their standing surfaces are located below the overpass body.

[0005] Furthermore, the platform frame also includes tie rods, the two ends of which are detachably connected to the base sidewalls and the suspension beam sidewalls.

[0006] Furthermore, the platform frame also includes tie rods, the two ends of which are detachably connected to the sidewalls of the suspension beam and the sidewalls of the suspension platform.

[0007] Furthermore, the platform frame also includes tie rods, the two ends of which are detachably connected to the sidewalls of the standing surface and the sidewalls of the connecting beams.

[0008] Furthermore, the base is a cuboid frame that is detachably connected by multiple steel plates and bolts.

[0009] Furthermore, the suspension beam is a cuboid frame consisting of multiple steel plates and bolts that are detachably connected.

[0010] Furthermore, the caster wheel is a swivel wheel with brakes.

[0011] By adopting the above technical solution, the beneficial effects of this utility model are:

[0012] This utility model is constructed from steel plates and bolts, offering high assembly flexibility. It can be assembled into various styles and sizes of frames as needed, suitable for most overpass construction and maintenance operations. The frame is equipped with braked casters for easy movement and stationary placement. During operation or downtime, the frame can be secured to the overpass using external fasteners and steel pipes to prevent movement, ensuring safety and reliability. The main materials of the frame are steel pipes, steel plates, bolts, and casters, all common materials available on the market. It is recyclable after initial fabrication, resulting in low overall cost. The frame is rigidly connected, preventing significant swaying even in windy conditions or when personnel move around, ensuring high work efficiency and safety. The entire platform is assembled from rigid steel, making it largely unaffected by the overpass's environment and widely applicable.
