Description

Technical Field

[0001] This application relates to the technical field of tarpaulin winding, and in particular to a tarpaulin winding device for industrial vehicles. Background Technology

[0002] Industrial vehicles in civil engineering often work in conjunction with excavators, loaders, belt conveyors, and other construction machinery to form loading, transporting, and unloading production lines for earthwork, sand, gravel, and bulk materials. When transporting bulk goods, existing industrial vehicles require tarpaulins to cover the cargo to prevent spillage, dust, or rain damage. Existing tarpaulin winding devices suffer from the following problems: Low efficiency due to manual operation: Traditional devices require manual climbing onto the top of the vehicle to unfold or roll up the tarpaulin, posing a risk of falls from height. Uneven winding tension: Manual winding easily leads to wrinkles and uneven wrapping of the tarpaulin, resulting in severe wear and tear on the edges after prolonged use. Utility Model Content

A connecting plate 3 is fixedly connected between the two sliders 8, and the connecting plate 3 is fixedly connected to one end of the tarpaulin 2. A fixed box 4 is fixedly connected to the front side. A drive motor 15 is fixedly installed on the inner wall of the fixed box 4. One end of the connecting shaft 20 movably passes through the side wall of the winding box 1 and is fixedly connected to the output end of the drive motor 15. A leveling mechanism for leveling the tarpaulin 2 is provided inside the winding box 1. The leveling mechanism includes two leveling rollers 21, both of which are rotatably installed inside the winding box 1. The tarpaulin 2 is located between the two leveling rollers 21. The drive motor 15 is connected to the leveling mechanism through a drive assembly, which includes a driving synchronous pulley 12, a driven synchronous pulley 13, a driving gear 16, and a driven gear 17. A connecting shaft 20 is sleeved on the side wall of one end inside the fixed box 4. The driving synchronous pulley 12, the lower leveling roller 21 has one end movably passing through the side wall of the winding box 1 and fitted with a driven synchronous pulley 13 and a driving gear 16, and the upper leveling roller 21 has one end movably passing through the side wall of the winding box 1 and fitted with a driven gear 17 that meshes with the driving gear 16. The driving synchronous pulley 12 and the driven synchronous pulley 13 are connected by a synchronous belt 14. The winding box 1 is equipped with a drive mechanism for driving the screw 9 to rotate. The drive mechanism includes a motor 24, a driving bevel gear 23 and a driven bevel gear 25. A connecting box 10 is fixedly connected to the left side of the winding box 1. A rotating shaft 22 is rotatably mounted inside the connecting box 10. Two gears are fitted on the side wall of the rotating shaft 22. A driving bevel gear 23 and a motor 24 are fixedly connected to the side wall of the connecting box 10. The output end of the motor 24 is fixedly connected to one end of the rotating shaft 22. One end of each of the two screws 9 passes through the fixed plate 7 and the side wall of the winding box 1 and is fixedly connected to a driven bevel gear 25 that meshes with the driving bevel gear 23. A protective shell 11 is fixedly connected to one side of the connecting box 10. The motor 24 is located inside the protective shell 11. Multiple mounting plates 5 are fixedly connected to the bottom of the side wall of the winding box 1. Mounting holes 6 are opened on the side walls of the multiple mounting plates 5. A control module (not shown in the figure) is installed inside the winding box 1. The drive motor 15 and the motor 24 are both electrically connected to the control module.

[0020] The implementation principle of the tarpaulin winding device for an industrial vehicle according to an embodiment of this application is as follows: All electrical components in this application are externally connected to a power supply and control switch. During use, the entire device is installed on the industrial vehicle via the mounting holes 6 on the mounting plate 5 and external fixing bolts. When the tarpaulin 2 needs to be unfolded, the drive motor 15 is started, driving the winding roller 19 to rotate via the connecting shaft 20, and the tarpaulin 2 is wound around the winding roller 19. Simultaneously, the motor 24 drives the rotating shaft 22 to rotate, and through the meshing of the driving bevel gear 23 and the driven bevel gear 25, the screws 9 on both sides rotate synchronously, driving the slider 8 to move laterally along the slide groove. The slider 8 pulls the edge of the tarpaulin 2 to move synchronously via the connecting plate 3, ensuring uniform lateral tension of the tarpaulin 2 during winding and avoiding wrinkles or deviations. During winding, the tarpaulin 2 first passes through the gap between two leveling rollers 21. The connecting shaft 20 drives the lower leveling roller 21 to rotate via the driving synchronous pulley 12, synchronous belt 14, and driven synchronous pulley 13. The lower leveling roller 21 drives the upper leveling roller 21 to rotate in the opposite direction through the meshing of the driving gear 16 and driven gear 17, forming a clamping and rolling action on the tarpaulin 2. The leveling roller 21 can eliminate small wrinkles on the surface of the tarpaulin 2, making the rolled-up tarpaulin 2 flat. The control module can control the proper operation between the drive motor 15 and the motor 24. The protective shell 11 encloses the motor 24 to prevent dust and rainwater from entering. A limit switch is provided at the end of the screw 9's stroke. When the slider 8 moves to the limit position, the machine automatically stops to prevent the tarpaulin 2 from being overstretched and damaged.

[0021] During this process, the unfolding and rewinding of the tarpaulin 2 are synchronously controlled by the drive motor 15 and the electric motor 24, and the tarpaulin 2 can be leveled by the leveling mechanism, which solves the problems of low efficiency and poor quality of traditional manual rewinding. It is especially suitable for industrial logistics and engineering transportation scenarios. Its high efficiency, safety and low consumption characteristics can significantly improve the operating efficiency and standardization of industrial vehicles, and have important market application value.
