Example Embodiment

[0036] Example one

[0037] reference figure 2 The tarpaulin storage box 6 is a cylindrical tube, and the tarpaulin inlet and outlet 60 is arranged on the upper side near the vehicle body. The tarpaulin inlet and outlet 60 is a strip-shaped mouth, which is arranged along the length direction of the tarpaulin storage box 6. , And the same length as the tarpaulin storage box 6. A rotating shaft 61 is arranged inside the tarp storage box 6, the rotating shaft 61 is arranged along the length direction of the tarp storage box 6, and the two ends are rotatably connected to the two ends of the tarp storage box 6. One side of the tarp 7 is fixed on the rotating shaft 61, and the other side extends outward from the tarp inlet and outlet 60, and is always kept outside the tarp inlet and outlet 60. With the rotation of the rotating shaft 61, the tarp 7 can It is wound on the rotating shaft 61 and is wound up and stored.

[0038] The tarpaulin 7 is located on the outer side of the tarpaulin storage box 6 with a clamping rod 71 parallel to the tarpaulin storage box 6. The clamping rod 71 is fixedly connected to the tarpaulin 7, and the diameter of the clamping rod 71 is larger than that of the tarpaulin inlet and outlet 60 When the tarpaulin 7 is tightened, the lever 71 is stuck on the outside of the tarpaulin storage box 6, which effectively prevents the tarp 7 from being too tightly closed and the entire tarpaulin storage box 6 cannot be pulled out. Three lashing ropes 72 are provided along the length of the clamping rod 71. The lashing ropes 72 are equally spaced on the clamping rod 71. The clamping rod 71 is connected with the tarp 7 around the carriage to the other side of the warehouse grid 32, and A tie rope 72 is used to tie the tarpaulin 7 and the warehouse gate 32 tightly.

[0039] In this embodiment, the driving device is a rocker 81 arranged at one end of the rotating shaft 61. The two ends of the rotating shaft 61 are rotatably connected to the two ends of the tarp storage box 6 through bearings. The end at the rear of the vehicle is from the end of the tarp storage box 6 Extending outwards, the rocking wheel 81 is sleeved on the rotating shaft 61, and the rocking wheel 81 is manually controlled to recover the tarpaulin 7, which is convenient to use.

[0040] The implementation principle of this embodiment is as follows: figure 1 with 3 In the initial state, the tarp 7 is contracted in the tarp storage box 6. When the tarp 7 needs to be used, pull the tie rope 72 to slowly pull the tarp 7 out of the tarp storage box 6, and the tarp 7 crosses the warehouse gate 32 The top of the tarpaulin is in rolling contact with the roller 322, crosses the carriage, and then moves down across the bin fence 32 on the other side until the tarpaulin 7 is fully unfolded, and the tarpaulin 7 reaches the middle position of the bin fence 32 on the other side. A binding part 321 for connecting the tie rope 72 is provided at the middle of the outer side of the warehouse gate 32 on the side. The position of the binding part 321 corresponds to the position of the tie rope 72 and is distributed along the length direction of the warehouse gate 32. The tying rope 72 is tightly tied to the binding part 321 to fasten the tarp 7; when the tarpaulin 7 needs to be recovered, the tying rope 72 is untie from the binding part 321, and the rocker 81 is manually rotated, The rocking wheel 81 drives the rotating shaft 61, and the rotating shaft 61 drives the tarpaulin 7 to be recovered. The tarpaulin 7 is gradually wound into the tarpaulin storage box 6 until it is completely wound on the rotating shaft 61 to complete the recovery of the tarpaulin 7.

Example Embodiment

[0041] Example two

[0042] reference Figure 4 In this embodiment, the driving device includes an elastic belt 82 connected at both ends of the rotating shaft 61, and a winding shaft 83 arranged below both ends of the tarp storage box 6. One end of the elastic belt 82 is connected to the winding shaft 82, and the other end is connected to the winding shaft 82. The end of the rotating shaft 61 can be stretched and wound on the rotating shaft 61, wherein the two ends of the rotating shaft 61 are connected to the two ends of the tarp storage box 6 through bearings, and extend outward from both ends, and the elastic belt 82 is wound around the rotating shaft. At the protruding end 61, the natural length of the elastic belt 82 is smaller than the protruding length of the tarpaulin 7.

[0043] The implementation principle of this embodiment is as follows: figure 1 with 4 In the initial state, the tarp 7 is contracted in the tarp storage box 6. When the tarp 7 needs to be used, pull the tie rope 72 to slowly pull the tarp 7 out of the tarp storage box 6, and the tarp 7 crosses the warehouse gate 32 And rolling contact with the rollers 322, cross the carriage, and then move down across the bin fence 32 on the other side until the tarp 7 is fully unfolded, and the elastic belt 82 is gradually moved from above and below the winding shaft 82. Stretched and wound on the rotating shaft 61, the tarp 7 reaches the middle position of the other side bin gate 32, and the tarp 7 is fastened and fixed by the tie rope 72. At the same time, the elasticity of the elastic belt 82 stretches the tarp 7; it needs to be recycled When the tarp 7 is used, the tie rope 72 is unbound from the binding portion 321, the rotating shaft 61 is reversed under the elastic force of the elastic belt 82, and the rotating shaft 61 drives the tarp 7 to be recovered, and the tarp 7 gradually moves into the tarp storage box 6 Winding until it is completely wound on the rotating shaft 61, the recovery of the tarpaulin 7 is completed.
