[0028] Based on Example 1:

[0029] During the use of the transport locomotive roof support of the utility model, when the transport locomotive carriage 1 is loaded with goods, the top of the carriage 1 is in an open state, so that large objects can be conveniently placed directly in the carriage 1 by hoisting;

[0030] After the cargo is loaded, the screw rod 3 can be driven to rotate by the power device, and the tail rod 6 can be controlled to move to the other end of the slide frame 2 under the principle of the lead screw. In this process, the tail rod 6 pulls the middle rod 5 through the connecting assembly to move until the head rod 4, each middle rod 5 and the tail rod 6 form a complete top cover bracket. Then, the personnel use the tarpaulin to cover and close the top of the carriage 1, and the top cover bracket supports the tarpaulin. Furthermore, the tarpaulin can be directly fixed on the outer surface of the top cover bracket, so that the tarpaulin follows the top cover bracket to shrink and deform, which is more convenient for personnel to use;
