Description

Technical Field

[0001] The utility model relates to the technical field of road transportation, in particular to a cargo covering device for road transportation. Background Art

[0002] Cargo transport vehicles are motor vehicles specially used for transporting goods. They are widely used in logistics, warehousing, commercial distribution and commodity delivery. In road transportation, especially long-distance transportation, the safety and protection of goods is an important issue. Effective cargo covering can not only protect the goods from external environmental damage such as wind, rain, dust, sand, etc., but also improve the safety and efficiency of cargo transportation.

[0003] Traditional cargo covering methods mainly rely on manual laying of tarpaulins, but manual laying of tarpaulins is time-consuming, especially in large trucks and in the case of frequent loading and unloading, resulting in low work efficiency. In addition, manual operation requires a lot of physical strength, especially in severe weather conditions, where the labor intensity of workers is greater, resulting in manually laid tarpaulins being prone to loosening and falling off. Especially when driving at high speeds or encountering severe weather such as strong winds, the tarpaulins may be blown away, causing damage to the cargo.

[0004] Therefore, there is an urgent need to provide a cargo covering device for automated road transportation. Utility Model Content

[0005] In order to overcome the problems of the traditional manual tarpaulin laying method, which is time-consuming, labor-intensive, poor covering effect, low safety and high maintenance cost, the utility model provides an automated cargo covering device for road transportation.

[0006] To solve the above problem, the present invention adopts the following technical solution: a cargo covering device for road transport, comprising a frame, a symmetrically distributed mounting seat fixedly connected to the top of the frame, a clamping rod provided on the mounting seat, a symmetrically distributed motor provided inside the frame, a symmetrically distributed fixing plate fixedly connected inside the frame, a screw rod rotatably installed on the fixing plate, the screw rod being connected to the output shaft of the motor, and a folding canopy being jointly provided with the screw rod, the folding canopy being composed of several frames and a waterproof tarpaulin, wherein only the first frame is connected to the screw rod by a thread, and the remaining frames slide on the screw rod.

[0007] Furthermore, fixed blocks are fixedly connected to both side surfaces of the frame, a fixed frame is clamped on the fixed block, a guide groove is provided on the fixed frame, a pull rod is slidably provided on the guide groove, a clamping plate is clamped on the pull rod, and the clamping plate is clamped on the screw position between the first frame and the second frame.

[0008] Furthermore, a connecting ring is sleeved on the pull rod, and an elastic member is connected between the connecting ring and the fixing frame.

[0009] Furthermore, a plurality of hooks are provided on the bottom of the fixing plate.

[0010] Furthermore, a placement box is provided on both sides of the frame.

[0011] Furthermore, a baffle is provided on the placement box.

[0012] Compared with the existing technology, the utility model has the following technical effects: 1. The device adopts the method of motor-driven screw rod to realize the rapid deployment and folding of the awning. The movement mode of the motor-driven screw rod has high load-bearing capacity and stability, which can ensure that the awning can be smoothly and reliably deployed and folded under various working conditions. It not only effectively improves the efficiency of cargo covering, but also significantly improves the safety of cargo transportation. In addition, it reduces the time and intensity of manual operation, reduces the labor burden of workers, and also reduces the risks caused by improper manual operation.

[0013] 2. Through the cooperation of the card plate and the elastic member, and by utilizing the resetting elastic force of the elastic member, the card plate can push the folding awning to fold and retract quickly when resetting, thereby accelerating the folding speed of the folding awning and improving the stability of the device.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figure 1-Figure 3 A cargo covering device for road transport includes a frame 1, a mounting seat 6 symmetrically distributed on the left and right is fixed to the top of the frame 1, a clamping rod 7 is provided on the mounting seat 6, a motor 2 symmetrically distributed on the left and right is provided inside the frame 1, a fixing plate 3 symmetrically distributed on the left and right is also fixed to the inside of the frame 1, the fixing plate 3 is located below the motor 2, a screw rod 4 is rotatably installed on the upper part of the fixing plate 3, the screw rod 4 is connected to the output shaft of the motor 2, and the screw rod 4 is jointly provided with a folding canopy 5, the folding canopy 5 is composed of several frames and waterproof tarpaulin, among which only the first frame and the screw rod are connected. The rod 4 is connected by a thread, and the remaining frames slide on the screw rod 4. When the motor 2 is started, the first frame can be driven by the screw rod 4 to move in the direction of the screw rod 4, and then the entire folding awning 5 is gradually unfolded or folded. Several hooks 14 are provided at the bottom of the fixing plate 3 to provide a fixing point so that the operator can use ropes to reinforce the awning to ensure its stability during transportation. The left and right sides of the frame 1 are provided with a placement box 15 for storing ropes. A baffle 16 is provided on the placement box 15 to close the placement box 15 to prevent the rope from falling out of the placement box 15 during transportation.

[0022] First, install the device on the truck bed. Two symmetrical fixing rods need to be welded to the truck bed in advance. After the two fixing rods are inserted into the corresponding mounting seats 6 on the top of the frame 1, the fixing rods are locked on the mounting seats 6 using the clamping rods 7 to ensure that the covering device will not loosen or shift during the entire transportation process. The installation of the device is completed. When the device is used, start the motor 2. The motor 2 will drive the first frame to move in a straight line through the screw rod 4. As the first frame moves, the folding awning 5 will gradually unfold to cover the goods in the entire truck bed, ensuring that the awning is fully unfolded and flat. After covering all the cargo and confirming that the awning has been fully unfolded and covered the cargo, turn off the motor 2 and stop the awning's unfolding action. When it is necessary to retract the folding awning 5, turn on the motor 2 again and control its output shaft to rotate in the opposite direction to move the first frame in the opposite direction. As the first frame moves in the opposite direction, the folding awning 5 will gradually be retracted until it is completely folded back to its initial position. After confirming that the awning has been fully retracted, turn off the motor 2 and stop the awning's folding action. If it is necessary to remove the covering device, first unlock the lever 7 and then remove the entire device from the truck bed.

[0023] Example 2: Based on Example 1, please refer to Figure 4 and Figure 5 The left and right sides of the frame 1 are fixed with fixed blocks 8, and the fixed blocks 8 are clamped with fixed frames 9. The fixed frames 9 are provided with guide grooves, and a pull rod 10 is slidably provided on the guide groove. A card plate 11 is clamped on the pull rod 10, and the card plate 11 is clamped on the position of the screw rod 4 between the first frame and the second frame to push the folding canopy 5 to retract.

[0024] See also Figure 5 The pull rod 10 is sleeved with a connecting ring 12, and an elastic member 13 is connected between the connecting ring 12 and the fixing frame 9. The elastic member 13 provides a reset elastic force for the pull rod 10 to assist the pull rod 10 in resetting.

[0025] When the folding awning 5 is gradually unfolded, the folding awning 5 will push the card plate 11 to move together. At this time, the card plate 11 slides along the guide groove and drives the pull rod 10 to move. The connecting ring 12 moves with the pull rod 10, so that the elastic member 13 is stretched. When the folding awning 5 is folded, the motor 2 reverses, and the screw rod 4 drives the first frame to move in the folding direction. Under the action of the reset elastic force, the elastic member 13 pulls the connecting ring 12 and the pull rod 10 to reset. When the pull rod 10 is reset, the card plate 11 is driven to reset. When the card plate 11 is reset, it will push the frames after the first frame to fold and retract, thereby assisting the retraction of the folding awning 5, thereby accelerating the folding speed of the awning and making the awning more stable during the folding process.
