The invention discloses a large-span assembled steel bridge which comprises a top plate, the top plate is fixedly mounted on a wall top, a connecting frame is fixedly mounted at the bottom of the top plate, bases are rotatably connected to the two sides of the connecting frame, the connecting frame and the two bases are distributed in a herringbone shape, an adjusting frame is mounted between the two bases, and each base comprises a bottom plate. Side plates are fixedly installed on the two sides of the bottom plates, the two side plates and the bottom plates are distributed in a U shape, sliding grooves are formed in the upper portions of the inner sides of the two side plates, limiting grooves are formed in the two sides of each sliding groove, a plurality of sealing plates are arranged in the sliding grooves, the two ends of each sliding groove are provided with inclined faces, and therefore the sealing plates can be inserted conveniently in the installation process, and the bottom plates are used for bearing cables. The bases are sealed through the sealing plates, the two bases rotate downwards to form a certain angle after installation, a triangular structure is formed between the two bases, and the gravity of the triangular structure is converted into a part of component force in the horizontal direction.
Description
technical field [0001] The invention relates to the technical field of cable installation equipment, in particular to a large-span assembled steel bridge frame. Background technique [0002] The cable tray is divided into trough type, tray type, ladder frame type, grid type and other structures. It is composed of brackets, brackets and installation accessories. Stability, but this method makes the installation process cumbersome and the connection effect is unstable. [0003] For example, a long-span bridge for cables disclosed by the patent publication No. CN107579486B includes a lifting mechanism, a bridge, and a support frame. The lifting mechanism is located under one side of the bridge, and the bridge is located below the support. Located on one side of the lifting mechanism, the lifting mechanism includes: a first support rod, a second support rod and a rotating drum. There is a ground below the rotating drum, and the bottom ends of the first supporting rod and the se...
