Description

Technical Field

[0001] This utility model relates to an automatic tarpaulin covering device for trucks, belonging to the technical field of truck tarpaulin covering. Background Technology

[0002] Tarpaulins, also known as waterproof cloth, are a high-strength, durable, and waterproof material. They typically have sturdy loops at the corners or edges for securing, hanging, or covering with ropes. Tarpaulins are essential equipment for trucks; when a truck is fully loaded, the tarpaulin covers the cargo to prevent it from getting wet and damaged during transport, and to prevent it from scattering onto the road or streets. They serve to waterproof and reinforce the cargo. Covering trucks with tarpaulins requires workers to climb onto the truck to perform the work. This involves placing the tarpaulin over the cargo, spreading it out, and then removing and folding it before unloading. It is a very labor-intensive task, not only inefficient but also dangerous, posing significant safety hazards.

[0003] Existing literature (CN218478469U) discloses a truck tarpaulin towing and covering device, comprising: a column; a rail-mounted truss hanger, mounted on the column; an electric hoist crane, installed on the rail-mounted truss hanger; a bracket, positioned below the rail-mounted truss hanger and close to one side of the column; and a support rod, horizontally erected on the support rod, the support rod having a lifting ring and a hook. The lifting ring is used to connect with the electric hoist crane, and the hook is used to connect with one side of the truck tarpaulin. This solution, by installing an electric hoist crane on the rail-mounted truss hanger and installing a bracket and support rod below the rail-mounted truss hanger, with the support rod having a lifting ring and hook, allows for the quick installation of one side of the tarpaulin onto the support rod via the hook, followed by the electric hoist crane connecting to the lifting ring, achieving rapid towing and installation of the tarpaulin. It has the advantages of convenient installation and lifting, and strong practicality. However, in use, the tarpaulin is draped on the support rod or can be easily removed, making it inconvenient for retrieval and storage. Utility Model Content

[0004] Based on the above, this utility model provides an automatic tarpaulin covering device for trucks to overcome the shortcomings of the prior art.

[0005] The technical solution of this utility model is: an automatic tarpaulin covering device for trucks, comprising: The covering unit includes a column, a rail truss hanger, an electric hoist crane, and a canopy support rod. At least two sets of the rail truss hangers are spaced apart on the column. The electric hoist crane is installed on the rail truss hanger. The canopy support rod is connected to the electric hoist crane by a suspension rope. The tent storage unit includes a support frame, a support roller, a tent retractor roller, and a drive mechanism. The support roller is disposed on the top of the support frame, the tent retractor roller is rotatably disposed on the support frame, and the drive mechanism can drive the retractor roller to rotate.

[0006] In one example, the tarpaulin pole is equipped with multiple sets of first hooks for connecting to grommets on the tarpaulin.

[0007] In one example, the support includes a base plate, a support plate, and a top plate. The support plates are disposed on both sides of the base plate, and the top plates are disposed on both sides of the top of the support plates. The support rollers are in two sets, each rotatably disposed between the two top plates.

[0008] In one example, the awning roller is positioned at the center of the support plate, and the driving mechanism is a drive motor fixed to the outside of the support plate, with the output shaft of the drive motor connected to the awning roller.

[0009] In one example, the roll-up roller has a row of second hooks along its length for connecting to the loops on the tarpaulin.

[0010] The beneficial effects of this utility model are as follows: Through the designated tarpaulin storage unit, the drive mechanism can rotate the tarpaulin retraction roller in both directions. Combined with the guidance of the support roller, this allows for the automatic and orderly storage of used tarpaulins on the retraction roller, or the smooth release of the tarpaulin during use. This effectively solves the problems of haphazard stacking and inconvenient retrieval of tarpaulins in existing technologies, achieving standardized and automated storage and management of tarpaulins. The second hook on the retraction roller and the first hook on the support rod can quickly and reliably connect or disconnect from the lanyard rings on the tarpaulin, greatly simplifying the steps of mounting and unmounting the tarpaulin.

Detailed Implementation

[0012] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0013] Please see Figures 1 to 4 This embodiment provides an automatic tarpaulin covering device for trucks, comprising a covering unit and a tarpaulin storage unit.

[0014] The canopy unit includes columns 11, rail-mounted truss hangers 12, electric hoist cranes 13, and canopy support rods 14. Four sets of rail-mounted truss hangers 12 are spaced apart on the columns 11. The electric hoist cranes 13 are mounted on the rail-mounted truss hangers 12. The canopy support rods 14 are connected to the electric hoist cranes 13 via lifting ropes 15. Multiple sets of first hooks 16 are installed on the canopy support rods 14 for connecting to the hoops on the tarpaulin.

[0015] The tent storage unit includes a support frame 21, support rollers 22, a tent-rolling roller 23, and a drive mechanism 24. The support frame 21 includes a base plate 211, support plates 212, and a top plate 213. Two support plates 212 are vertically fixed to both sides of the base plate 211, and the top plate 213 is fixedly installed on both sides of the top of the support plates 212. Two sets of support rollers 22 are rotatably mounted between the two top plates 213, with a gap between them. The tent-rolling roller 23 is rotatably mounted in the middle of the support frame 21. The drive mechanism 24 is a drive motor fixed to the outside of the support plate 212. The output shaft of the drive motor is connected to the tent-rolling roller 23, thus enabling the drive motor to drive the rotation of the tent-rolling roller 23. To facilitate the rolling up of the tent fabric, a second row of hooks 25 is provided along the length of the tent-rolling roller 23 for connecting to the hoops on the tent fabric.

[0016] The working principle of the above-mentioned automatic tarpaulin covering device for trucks is as follows: When rolling up the tarpaulin, first drive the truck to the underside of the rail truss 12 and bring one side of the truck close to the support 21. Then pull one side of the tarpaulin and pass it through the gap between the two support rollers 22. Then hang it on the second hook 25. Drive the tarpaulin roller 23 to rotate through the drive mechanism 24, and then roll up the tarpaulin on the tarpaulin roller 23. It should be noted that the tarpaulin does not need to be completely rolled up. Leave its tail on the support roller 22 for easy tarpaulin covering.

[0017] When draping the tarpaulin, first drive the truck under the rail truss 12, hang one side of the tarpaulin on the tarpaulin support rod 14 via the first hook 16, then move the electric hoist crane 13 directly above it. The electric hoist pulls the tarpaulin support rod 14 and one side of the tarpaulin upwards. The drive mechanism 24 drives the tarpaulin retraction roller 23 to reverse and release the tarpaulin synchronously. When the tarpaulin on that side has moved a certain distance beyond the top of the truck, the electric hoist crane 13 moves horizontally along the rail truss 12, pulling the tarpaulin on that side to the other side of the truck. After the tarpaulin is released, stop moving and remove the tarpaulin from the second hook 25. Finally, the electric hoist crane 13 pulls the tarpaulin support rod 14 and the tarpaulin downwards, so that the tarpaulin covers the top of the truck. Remove the first hook 16 and tie the tarpaulin to the truck.

[0018] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
