Further, a rear limiting baffle 11 and a rear anti-skid layer 12 are arranged on the top surface of the auxiliary moving frame 1, a matching groove 13 and a positioning groove 14 are arranged on the front side wall of the auxiliary moving frame 1, an upper anti-skid layer 22 and a lower anti-skid layer 204 are respectively arranged on the top surface and the bottom surface of the main moving frame 2, and a positioning column 203 matched with the positioning groove 14 is arranged on the rear side wall of the main moving frame 2; the opposite walls of the two side limiting guide baffles 21 are provided with cushions 211 protruding outwards.

The working principle of the invention is as follows:

1. when loading and transporting, the travelling wheels 281 are in an extending state, the driving wheel 241 positioned below is attached to the bottom surface of the transmission block 23, the support roller 232 is attached to the top surface of the top plate of the travelling frame 28, the top surface of the main moving frame 2 and the top surface of the auxiliary moving frame 1 are on the same plane, the main moving frame 2 and the auxiliary moving frame 1 are pulled apart by a certain range according to the length of the transported steel material and the steel material is placed on the main moving frame 2 and the auxiliary moving frame 1, the front end and the rear end of the steel material are limited by the lifting plate 5 and the rear limit baffle 11, the adjusting rod 32 is rotated by rotating the adjusting nut 33, the adjusting rod 32 rotates to drive the main moving block 35 to move forward and the positive and negative thread lead screw 214 to rotate, the travelling wheels 281 are not affected because the driving wheel 241 is attached to the bottom surface of the transmission block 23, and the position adjustment can be continuously performed by the two side limit, after the completion, the steel products can be transported and moved;

2. when unloading is carried out, the adjusting nut 33 rotates reversely, the main moving block 35 moves backwards and the positive and negative thread lead screw 214 rotates reversely, the driving block 23 moves backwards to be close to the driving wheel 241 at the upper end so as to jack up the guide wheel 261, the walking wheel 281 retracts into the adjusting through groove 201 under the action of the return spring 271, in the whole process, the whole main moving frame 2 descends to the ground due to the retraction of the walking wheel 281, but steel materials on the main moving frame 2 are always kept in the same horizontal state due to the rising of the guide wheel 261, in addition, in the process that the main moving frame 2 descends to the ground, the automatic lifting plate 5 at the lower end retracts into the vertical through groove 207, due to the meshing effect of the transmission gear 52 and the straight tooth part 51, the automatic lifting plate 5 at the upper end also retracts into the vertical through groove 207, so that the front end of the steel materials is not limited, unloading is convenient, at this time, the two synchronous containing discs 44 rotate simultaneously to contain the steel wire ropes 45, and the auxiliary moving frame 1 pushes the steel materials to move forwards so that the steel materials continuously extend out of the main moving frame 2 to be discharged;

in addition, the main moving frame 2 and the sub moving frame 1 can be assembled and combined through the positioning groove 14 and the positioning column 203, thereby facilitating storage.
