[0023] like Figure 1 and Figure 2 As shown, a truck tarpaulin covering device includes two mobile bases 2 and a crossbeam 6. The two mobile bases 2 are arranged horizontally at intervals. A vertical frame 1 is installed on the top of the mobile base 2. At least two universal wheels 3 are installed on the bottom of the mobile base 2. A rope fixing frame 4 is installed on the vertical frame 1. A sleeve 9 is also installed horizontally on the top of the vertical frame 1. Figure 3As shown, a latch 7 is installed on the sleeve 9, and both ends of the crossbeam 6 are inserted into the sleeve 9 respectively, and a plurality of pin holes 8 are opened at both ends of the crossbeam 6, and the latch 7 is inserted into the corresponding pin holes 8. A pulley 5 is also installed on the sleeve 9, and the pulley 5 can rotate relative to the sleeve 9. During installation, it is necessary to adapt the width between the two upright frames 1 according to the width of the vehicle cargo box, and the spacing between the two upright frames 1 is required to be greater than the width of the cargo box. In this embodiment, by changing the position of the crossbeam 6 in the sleeve 9, the spacing between the two upright frames 1 can be changed, so as to adapt to the tarpaulin covering of different cargo boxes. Of course, during design, the height of the upright frame 1 is higher than the height of the cargo box. When in use, the draw rope on the tarpaulin is wound around the pulley 5, and the end of the draw rope is tied to the draw rope fixing frame 4, and then the covering device is moved from the rear of the cargo box to the head of the cargo box. At this time, the tarpaulin is pulled by the covering device and gradually covers the cargo box from the rear to the head. When the covering device moves to the head, the tarpaulin at the rear is tied tightly to the hook on the cargo box through the rope, and then the draw rope is untied from the draw rope fixing frame 4, and the pin 7 is removed, thereby separating the two upright frames 1, and then the upright frame 1 is moved horizontally, so that the upright frame 1 is away from the cargo box, and finally the skirt of the tarpaulin is tied tightly to the hook on the cargo box through the rope, thereby realizing the covering of the truck tarpaulin.

[0024] In this embodiment, if Figure 1 As shown, the mobile base 2 is a channel steel with an opening facing upward, and the top of the stand 1 is welded in the groove of the channel steel. The opening of the channel steel faces upward, so that the mobile base 2 has a receiving groove, in which work tools can be placed to avoid loss of tools.

[0025] In this embodiment, if Figure 1 As shown, inclined reinforcing rods 10 are installed on the front and rear sides of the bottom of the frame 1. The bottom of the reinforcing rod 10 is welded in the groove of the channel steel. The reinforcing rod 10 can ensure the structural strength of the frame 1 and avoid bending of the frame 1 during the tarpaulin pulling process.

[0026] In this embodiment, if Figure 1 As shown, there are two universal wheels 3, which are respectively located at the front and rear ends of the mobile base 2. The installation of the universal wheels 3 belongs to the existing technology and will not be described in detail. The base of the universal wheel 3 can be installed in the channel steel by bolts.

[0027] In this embodiment, if Figure 3 As shown, a fork is fixedly mounted on the sleeve 9, the fork is located on the outside of the stand 1, the pulley 5 is installed in the fork through a pin, and the fork and the sleeve 9 are welded together. The pulley 5 can save effort when the tarpaulin is first pulled up.

[0028] In this embodiment, if Figure 3As shown, the pin holes 8 at both ends of the beam 6 are opened at equal intervals. Preferably, the spacing between two adjacent pin holes 8 at both ends of the beam 6 is 10 mm, so the operator can quickly adjust the width between the two uprights 1 according to the width of the cargo box, thereby adapting to the width of the cargo box.

[0029] In this embodiment, if Figure 1 As shown, the pull rope fixing frame 4 is a horizontal rod, the horizontal rod is longitudinally arranged, and the horizontal rod is vertically welded to the vertical frame 1. The binding method of the pull rope and the pull rope fixing frame 4 belongs to the existing technology and will not be repeated here.

[0030] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
