[0045] Reference Figures 1 to 6 The utility model provides a truck tarpaulin 600 covering device, comprising:

[0046] The telescopic support rod 100 is located at one end of the truck deck near the front of the truck. One end of the telescopic support rod 100 is connected to the truck, and the other end is connected to the first rope pulley 111;

[0047] Auxiliary frame 200, the auxiliary frame 200 is located at the rear of the vehicle, one end of which is overlapped with the cargo in an inclined state, and the end of the auxiliary frame 200 close to the cargo has a second rope pulley 250;

[0048] The driving unit 300 includes a rope reel 340 , and the traction rope 500 is wound around the first rope pulley 111 and the second rope pulley 250 in sequence by the rope reel 340 to connect to the tarpaulin 600 .

[0049] The tarpaulin 600 covering device proposed in this solution is a drag-type tarpaulin 600, that is, when unloading, the tarpaulin 600 can be completely separated from the truck to facilitate unloading and loading. After loading is completed, the tarpaulin 600 is covered on the goods.

[0050] When applying the tarpaulin 600, the tarpaulin 600 is positioned on the ground at the rear of the vehicle. The auxiliary frame 200 is first connected to the cargo at the rear of the vehicle, with the auxiliary frame 200 positioned diagonally to the ground. The traction rope 500 is unwound by the rope reel 340, sequentially wound around the first rope pulley 111 and the second rope pulley 250, and connected to the tarpaulin 600. The traction rope 500 is then reeled in by the drive unit 300. As the traction rope 500 gradually contracts, the tarpaulin 600 slides to the auxiliary frame 200 and gradually slides along the auxiliary frame 200 to the top of the cargo at the rear of the vehicle, gradually covering the cargo surface, completing the tarpaulin 600's covering. The provision of the auxiliary frame 200 smooths the movement path of the tarpaulin 600, resolving the technical issue of the inconvenience of dragging the tarpaulin 600 from the rear of the vehicle to the top of the cargo. As the traction rope 500 gradually reels in, the tarpaulin 600 can pass over the first rope pulley 111, completely covering the cargo.

[0051] Specifically, the drive unit 300 comprises an active rod 320 and a driven rod 330, which are connected and disconnected via a transmission connector 360. When applying the tarpaulin 600, the active rod 320 and the driven rod 330 are connected, and the motor 310 drives the rope reel 340 to reel in the traction rope 500. To remove the tarpaulin 600, the active rod 320 and the driven rod 330 are disconnected, allowing the operator to directly drag the tarpaulin 600 from the top of the cargo to the ground. Furthermore, the driven rod 330 is supported by a bearing 350, ensuring stable rotation and smooth movement during unwinding and rewinding.

[0052] Furthermore, the telescopic support rod 100 includes a telescopic rod 110. A first pulley 111 is provided at one end of the telescopic rod 110, and a fixed pin hole 112 and a rotating pin hole 113 are provided at the other end. The rotating pin hole 113 realizes a rotational connection between the telescopic rod 110 and the truck. When covering and removing the tarpaulin 600, the telescopic rod 110 is rotated to a vertical position, and the pin engages with the fixed pin hole 112 to maintain the telescopic rod 110 in the vertical position for use. After the operation of the tarpaulin 600 is completed, the pin is pulled out of the fixed pin hole 112, and the telescopic rod 110 is rotated to a horizontal position. The pin then engages with the fixed pin hole 112 to maintain the telescopic rod 110 in the horizontal position for storage, thereby reducing the impact of the telescopic rod 110 on the truck during travel. When the telescopic rod 110 is in the horizontal position, the telescopic rod 110 can be retracted. It is understood that the truck has corresponding holes that cooperate with the fixed pin hole 112, the rotating pin hole 113, and the pin rod. It should be noted that other structures that can rotate and fix the telescopic rod can be selected on different types of trucks. Since the rotation and fixing structures are existing technologies, they will not be described in detail.

[0053] The rotation pin holes 133 of the two telescopic rods 110 may be at different heights to enable the two telescopic rods 110 to be stacked and stored.

[0054] The telescopic distance of the telescopic rod 110 can be adjusted according to the height of the goods. In order to cover the goods, the telescopic rod 110 is higher than the goods by a certain distance.

[0055] When the telescopic rod 110 is in a vertical state and is covering the tarpaulin 600, the upper part of the telescopic rod 110 will be subjected to a force along the traction rope 500 toward the tarpaulin 600. Under the action of the force, the telescopic rod 110 will bend to a certain extent. In order to prevent the telescopic rod 110 from bending and deforming due to excessive force, a sliding bracket 400 is provided. The slip ring 410 in the sliding bracket 400 is sleeved on the outer periphery of the telescopic rod 110 and can slide along the direction of the telescopic rod 110. The top rod 420 in the sliding bracket 400 is used to abut against the cargo. After the top rod 420 abuts against the cargo, it becomes a fulcrum of the support rod, reducing the possibility of deformation and bending of the telescopic rod 110 due to the force. According to different work requirements, multiple sliding brackets 400 can be provided, which is not limited here.

[0056] Specifically, the telescopic rod 110 is extended and retracted by a pneumatic cylinder (not shown). Trucks typically have air brakes, so the cylinder can be directly connected to the truck's air tank, reducing the difficulty of retrofitting the covering device onto a truck. Of course, the telescopic rod 110 can also be driven by other devices, as long as they can achieve the function of driving the telescopic rod 110 to extend and retract.

[0057] During the reeling process, the traction rope 500 may deviate from the first rope pulley 111, causing the tarpaulin 600 to slip and reduce the tarpaulin's coverage. To address this, limit rods 120 are provided. These limit rods 120 are located on either side of the first rope pulley 111 and are magnetically connected to the telescopic rod 110. These limit rods 120 prevent the traction rope 500 from deviating from the first rope pulley 111 during the reeling process.

[0058] After the positioning rod 120 is installed, it will block the tarpaulin 600, making it difficult for the tarpaulin 600 to pass around the first rope pulley 111. To achieve the positioning of the traction rope 500 and ensure the covering effect of the tarpaulin 600, the first rope pulley 111 and the second rope pulley 250 can be selected as rollers with limiting grooves. The traction rope 500 is located in the limiting grooves and rotates around the rollers. The rollers with limiting grooves can both limit the movement path of the traction rope 500 and not affect the movement path of the tarpaulin 600.

[0059] Specifically, the auxiliary frame 200 includes an auxiliary rod 210 , a connecting rod 220 , a bridge rod 230 and a pulley 240 .

[0060] The auxiliary rod 210 and connecting rod 220 are both detachable, allowing the auxiliary frame 200 to be adjusted to suit different working environments, depending on the width of the truck and the height of the cargo. The pulley 240 on the connecting rod 220 reduces friction during the tarpaulin 600's covering process, converting sliding friction into rolling friction. Furthermore, the pulley 240 can lift the tarpaulin 600 to a certain height, reducing the contact area between the tarpaulin 600 and the auxiliary frame 200 and further reducing friction, allowing the tarpaulin 600 to be quickly and stably applied to the cargo.

[0061] The auxiliary frame 200 also has a connecting rod 230 structure, which can be an angular structure, that is, a "human" structure, for stably connecting the auxiliary frame 200 as a whole to the cargo. The outer periphery of the connecting rod 230 can be wrapped with a flexible sheath to prevent the connecting rod 230 from scratching the cargo.

[0062] Furthermore, both ends of the connecting rod 220 extend outward a predetermined distance and are provided with angled corners 221, with the curved surfaces of the angled corners 221 facing the tarpaulin 600. The extension of the connecting rod 220 allows the tarpaulin 600 to cover the cargo on both sides during tarpaulin 600 application. The angled corners 221 prevent the ends of the connecting rod 220 from scratching the tarpaulin 600 during the tarpaulin application process. It is understood that the ends of the connecting rod 220 can also be smoothed to remove any sharp edges.

[0063] Furthermore, if the size of the tarpaulin 600 is large, wrinkles will appear on the large-sized tarpaulin 600 during the covering process and it is difficult to move the entire tarpaulin in a flat state. For this reason, a supporting rod 610 is provided. The supporting rod 610 is perpendicular to the moving direction of the tarpaulin 600 and is close to the traction rope 500, supporting one end of the tarpaulin 600 in a flat state to facilitate the covering of the tarpaulin 600.

[0064] The above are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made based on the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, within the inventive concept of the present invention, are included in the patent protection scope of the present invention.
