The invention discloses a supporting framework for a transportation semitrailer, and relates to the technical field of transportation semitrailers, the supporting framework mainly comprises two longitudinal beams and a plurality of cross beams fixedly arranged between the two longitudinal beams, at least two groups of sliding assemblies are arranged on each longitudinal beam, each sliding assemblycomprises a sliding seat, a sliding block and a screw rod, and the sliding seat is fixedly arranged on the longitudinal beams; a sliding hole is machined in the upper surface of the sliding base, thesliding block is movably matched with the sliding hole, the lead screw is arranged on the sliding base and is in threaded connection with the sliding block, and the sliding block can slide along thesliding hole by rotating the lead screw; each sliding block is provided with a positioning block, and each positioning block is provided with a connecting mechanism used for being connected with an assembling hole in an external platform. The sliding assemblies are arranged at the corresponding connecting positions of the two sides of the longitudinal beams, assembling operation of different external platform forms is coped with in a sliding adjusting mode, and the beneficial effects of being easy and convenient to adjust and high in continuity are achieved.

    本发明公开了一种运输半挂车用支撑骨架,涉及运输半挂车技术领域,它主要包括两根纵梁以及固设于两根纵梁之间的多根横梁,每根纵梁上均设置有至少两组滑动组件,滑动组件包括滑座、滑块和丝杆,滑座固设于纵梁,且滑座上表面加工有滑孔,滑块活动配合于滑孔,丝杆设置于滑座上,且丝杆与滑块丝接,转动丝杆,能够使滑块沿滑孔滑动;每个滑块上均设置有定位块,定位块上安装有用于连接外部平台上装配孔的连接机构。本发明通过在其纵梁两侧对应连接位置处设置滑动组件,通过滑动调节的方式来应对不同外部平台形式的装配作业,具有调节简便且连续性较强的优点。
