Description

Technical Field

[0001] This utility model relates to the field of bridge engineering technology, specifically to a transport device for reinforcing steel truss girders of continuous box girders under non-navigable conditions. Background Technology

[0002] A steel truss is a truss structure beam made of steel, typically composed of an upper chord, lower chord, and web members (including vertical and diagonal members) connected by nodes. The truss structure, through the rational arrangement of its members, transfers loads to the supports, fully utilizing the tensile and compressive strength of steel. It has advantages such as light weight, high strength, and high stiffness. In non-navigable conditions (where natural conditions such as river width, depth, and topography, or human restrictions such as bridges, dams, and waterway management prevent normal navigation of ships), specialized water transport equipment is required to transport steel trusses.

[0003] Existing transmission devices are typically unpowered platforms with multiple pontoons mounted at the bottom, moving on the water surface by being pulled by tow ropes. The pontoons at the bottom of existing transmission devices are usually fixed in place, making them impossible to replace or disassemble for maintenance. During the transport of the steel truss, the pontoons may collide with rocks accumulated at the bottom of the river, causing damage to them and reducing the buoyancy of the transmission device, thus affecting the transmission operation. Furthermore, the existing platforms for placing transmission devices usually do not have structures to secure the steel truss. During the transportation operation, large waves in the river may cause the transmission device to shake violently, causing the steel truss to fall into the water.

[0004] Therefore, it is necessary to provide a new continuous box girder reinforced steel truss girder transport device under non-navigable conditions to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a continuous box girder reinforced steel truss transport device under non-navigable conditions.

[0011] Preferably, one end of each set of straps is provided with a through hole, and the inside of each set of through holes is movably connected with a first bolt. The two sets of first bolts are respectively threadedly connected to the first threaded hole. The straps can be installed and fixed by the first bolts cooperating with the first threaded hole.

[0012] Preferably, each of the two sets of first bolts has a rotating handle fixedly connected to its top, allowing the first bolt to be rotated easily via the rotating handle.

[0013] Preferably, guardrails are fixedly connected to both sides of the placement plate to prevent the steel truss beam from falling from the side.

[0014] Preferably, a traction pile is fixedly connected to one side of the support frame, and two sets of traction piles are provided, which can be used to easily connect the traction rope.

[0015] Preferably, each of the four corners of the placement plate is fixedly connected to a support column, and the top of each of the multiple support columns is fixedly connected to a loop.
