And the load of the current road transport heavy truck is basically tens of tons, so that one truck can transport three to four rolls at most, and can only transport one roll for a large steel coil with tens of tons. Therefore, the steel coil is not easy to be transported by a truck, and the dangerous efficiency is low, so that the steel coil is transported by the truck only suitable for short-distance transportation. The railway transportation is most suitable for being used as steel coil transportation because of large carrying capacity and high speed. Railway transportation is therefore preferred when transporting steel coils nationally.

However, in railway transportation, rolling of the steel coil during transportation is still an unavoidable problem. At present, in order to prevent the steel coil from rolling in the transportation process, old measures such as sleepers, rubber supports and the like are adopted, and the effect is not ideal. Often because intensity is insufficient, or shift and cause the coil of strip still can take place to roll in transit in the transportation, although railway transportation can not cause the accident because of the roll of coil of strip, the roll of coil of strip still can cause the damage to coil of strip outward appearance, influences the delivery of goods, takes place the roll of coil of strip simultaneously and still can cause the loading and unloading degree of difficulty of coil of strip to increase. In addition, rolling prevention means such as sleepers and rubber supports are still not well controlled when steel coils are loaded, because the steel coils are not used as reference standards, the positions are not well placed, the distance is large, the useless effect is achieved, the steel coils are overhead due to the small distance, and the rolling prevention effect is still greatly reduced.

The hump 2 comprises a large hump 201 and a small hump 202, and how the hump is arranged is not limited, and the sizes of the adaptive steel coils are different according to different models. The large hump 201 and the small hump 202 include medial and lateral working arms. As shown in fig. 1, four large humps 201 are respectively arranged around the base frame 1, four small humps 202 are arranged in the middle of the base frame 1, and the reversible headrest 5 is installed in the four small humps 202 in the middle, so that the size of the hump 2 can be changed through the reversible headrest 5 to adapt to the placement of different types of steel coils.

The turnover back cushion 5 is connected with the humps 2, the turnover back cushion 5 is rotationally switched between an idle state and a working state, when the turnover back cushion 5 is in the idle state, the turnover back cushion 5 is positioned between two adjacent humps 2, the size of a groove 3 formed by the two adjacent humps 2 is the maximum, an oversized steel coil can be placed at the groove, when the turnover back cushion 5 is in the working state, the bottom of the turnover back cushion 5 is attached to a first working surface on the humps 2, a second working surface is flush with the first working surface of the adjacent large humps 201, a hump 2 with a larger size can be formed by being matched with the original humps 2, the size of the groove 3 is the minimum, and two large and medium-sized steel coils can be placed at the moment.

As shown in figure 2, the inner working arm of hump 2 is longer than the outer working arm and is lapped on the top of the outer working arm, and the two working arms form an included angle of 90 degrees. Therefore, the method can cope with huge pressure brought by rolling trend of the steel coil due to inertia caused by acceleration and deceleration during steel coil transportation.

As shown in fig. 4, the bottom of the hump 2 is provided with a hinge base 20, and the hinge base 20 is formed by installing two L-shaped steel plates 21 back to back at intervals of 30 mm, wherein the thickness of the L-shaped steel plates is 10 mm, and the width of the L-shaped steel plates is 50 mm.
