The invention provides a lightweight dovetail girder. The lightweight dovetail girder comprises a girder body front section; the beam body middle section is fixedly mounted on one side of the beam body front section, and the beam body rear section is fixedly mounted on the other side of the beam body middle section; the supporting beam is arranged on the outer surface of the rear section of the beam body and comprises a supporting plate, sliding blocks are fixedly installed on the two sides of the supporting plate, sliding grooves are formed in the front sides of the sliding blocks, communicating holes are formed in one sides of inner cavities of the sliding grooves, the middles of the inner cavity walls of the communicating holes communicate with sliding cavities, and extrusion devices are arranged on the two sides in the sliding cavities. According to the lightweight dovetail girder, the limiting rods of the clamping devices are embedded into the clamping grooves through the restoring elastic force of the springs, so that the supporting beams are limited in the rear section of the girder body, the lightweight dovetail girder is simple in structure and high in practicability, the supporting beams can be rapidly disassembled, and the lightweight dovetail girder is installed at multiple positions of the surface of the rear section of the girder body; and meanwhile, the weight of the dovetail girder is reduced, and the weight of the girder body is reduced.

    本发明提供一种轻量化燕尾大梁,包括:梁体前段;梁体中段固定安装于梁体前段的一侧,梁体中段的另一侧固定安装有梁体后段;支撑梁设置于梁体后段的外表面,支撑梁包括支撑板,支撑板的两侧均固定安装有滑块,滑块的前侧开设有滑槽,滑槽内腔的一侧开设有连通孔,连通孔内腔壁的中间连通有滑腔,滑腔内部的两侧均设置有挤压装置。本发明提供一种轻量化燕尾大梁,通过弹簧的复原弹力使得卡接装置的限位杆嵌入进卡槽的内部,使得支撑梁在梁体后段内被限制,本装置结构简单,实用性强,可以快速拆支撑梁并且安装在梁体后段表面的多个位置,适应承载不同长度的货物,同时减轻了燕尾大梁的重量,轻量化梁体。
