[0010] Preferably, a lifting lug is provided on the outer side surface of the column.

[0011] Packaging process: First, wrap a layer of rubber on the contact parts of the two railway passenger car underframes and the contact parts of the railway passenger car underframe and the supporting bracket, and install the passenger car underframe steel structures one by one into the supporting bracket through a gantry crane. The passenger car underframe steel structures are limited by limiting grooves, and the clamping plates on both sides of the supporting bracket are clamped and fixed to the passenger car underframe steel structures through nuts. The clamping plates are tightened by emergency pull rods, and multiple passenger car underframe steel structures are clamped on both sides to make the railway passenger car underframe and the packaging rack become a whole. The bolts at the top of the clamping plate are used for limiting and clamping the pressing plate, which not only prevents the components from sliding against each other, but also allows the railway passenger car underframe steel components to be lifted as a whole through the lifting ears. After packaging is completed, it can be lifted onto a flatbed truck or loaded into an open-top container, and the packaging rack is fixed to the flatbed truck or container through steel wire ropes, and covered with a rainproof tarpaulin as needed.

[0012] Beneficial effects achieved by this utility model:

[0013] (1) The support bracket is made of channel steel welded and overlapped, with a simple and reliable structure and good load-bearing effect; the base is plywood-padded, and during the packaging process, the contact parts between the bus chassis steel structure parts and the bus chassis steel structure parts, as well as the contact parts between the bus chassis steel structure parts and the support bracket and fastening devices are wrapped with rubber to protect the chassis steel structure and avoid damage to the components during transportation;

[0014] (2) The clamping plate of the fastening device is fixed by a snap-on method, and the emergency pull rod is fixed by a nut. It is easy to disassemble and assemble and can be recycled and reused. The emergency pull rod is easy to operate and can be clamped and disassembled at any time.
