With the great trend of 'revolving iron' for steel transportation, the transportation amount of open trucks for steel products in steel mills is gradually increased, when the open trucks are transported into bundles of bars or pipes, taking the bars as an example, railway departments require that more than 2 lines of strip-shaped grass support pads or straw ropes are paved between goods and a truck floor and among layers, and more than 12 grass support pads are needed to be paved on each truck skin according to the loading of three layers of goods. The straw rope has the advantages that the materials are environment-friendly, but the labor cost of harvesting, drying, storing and processing of the straws is continuously increased, the cost advantage does not exist, and the following problems are also existed: (1) as the rice in rural areas is harvested and mechanized, the straws are crushed and returned to the field, and the straw resources are increasingly deficient; (2) the warehouse is required to be stacked, the rain cannot be drenched, and the fire-fighting requirement is high; (3) a lot of broken grass is left on the loading site every time, so that the environmental sanitation is influenced, and the site needs to be cleaned in time; (4) the straw cushion is seriously deformed after being used and can only be used once. The suppliers worry about insufficient supply of the straw materials, and if the delivery amount of the open wagon is increased, the problem of the supply of the straw is more prominent, and the steel delivery of the open wagon is seriously influenced.

Since the straw rope is only used once, with the gradual reduction of straw resources and the continuous increase of labor cost, the advantages of using the straw rope to cushion cargoes do not exist, and the development of a composite material support cushion which replaces a straw scheme and is repeatedly used for many times is a future trend. Chinese patent application 201010570162.0 discloses a rubber cushion bar, which replaces the wood or steel used when piling up and putting or transporting large-size steel pipe articles, the rubber cushion bar includes a cushion bar body and a lining steel wire arranged inside the cushion bar body, although the scheme has a simple structure, it can replace the wood or steel used originally, if the scheme is used to make the specification of the strip-shaped grass support pad D70 (width 165mm, height 80mm, length 2000 mm) of the related standard TBT 3079.2-2003 loading reinforcement material and device of the railway industry, the following problems exist: (1) because the rubber cushion rod in the scheme is a solid rubber rod with a steel wire lining, the weight of a single rubber cushion rod is more than 20kg, the manual carrying is not facilitated, and the transportation cost is increased; (2) when the bar materials are loaded, the end of the support cushion is required to be exposed out of the edge of the goods and is not less than 100mm, namely, when each layer of goods is full of the width of the open wagon, the support cushion is also arranged on the side surface, and the support cushion is required to be bent from the bottom surface to the side surface at the joint of the side surface and the bottom surface of the open wagon. The edges of the two sides of the rubber cushion bar are difficult to bend, and the requirement can not be met.
