[0023] like Figures 1-4 As shown, this utility model discloses a hand-cranked tarpaulin device for underground sand and gravel transportation, comprising two oppositely distributed side plates 1. A winding shaft 6 is rotatably connected between the two side plates 1 via bearings. One end of the winding shaft 6 extends to the outside of the side plate 1 and is equipped with a crank handle 5. The crank handle 5 facilitates the rotation of the winding shaft 6 by operating the crank handle 5, thereby winding the tarpaulin 2. The tarpaulin 2 is wound on the winding shaft 6. Ropes 4 are fixedly connected to the side walls of the two side plates 1. The ends of the ropes 4 away from the side plates 1 are fixedly connected to uprights 3. The bottoms of the side plates 1 and the uprights 3 are fixedly connected to the edge of the vehicle frame. Studs 7 are provided at the bottom of the side plates 1 and the uprights 3. The bottom of the studs 7 penetrates the vehicle frame and is threaded with nuts 8. The studs 7 facilitate the fixed connection of the side plates 1 and the uprights 3 to the vehicle frame, so that the two side plates 1 are installed on both sides of the vehicle body near the front end, and the two uprights 3 are installed on both sides of the rear end of the vehicle body, so that the entire vehicle body can be covered when the tarpaulin 2 is unfolded. The two side walls of the tarpaulin 2 are slidably connected to the ropes 4 via a limiting structure. The limiting structure includes limiting rings 10. At least eight equally spaced through holes 9 are provided along the length of each of the two long edges of the tarpaulin 2. Each through hole 9 contains a limiting ring 10. The limiting rings 10 are fitted onto the outside of the ropes 4 and slidably connected to them. Through the cooperation between the limiting rings 10 and the ropes 4, the tarpaulin 2 will not collapse when it is unfolded, thus achieving a good covering effect.
