TECHNICAL FIELD

[0001] The present application relates to the technical field of cargo covering devices, in particular to a device for automatically covering a flexible covering. BACKGROUND

[0002] During the stacking or transportation of goods, it is often necessary to cover one or more layers of flexible covering to protect or bundle the goods accordingly. For example, after loading the goods, a tarpaulin is usually needed to cover the goods to prevent them from being damaged by sun and rain during transportation.

[0003] Currently, tarpaulin covering work is basically done by manually climbing onto the top of the vehicle or the top of the stacked goods. Manual covering is inefficient, poses a risk of falling from a high altitude, and risks damaging the product quality due to the trampling of personnel. In related technologies, some devices have gradually emerged that can automatically cover the tarpaulin for a truck, such as the automatic tarpaulin covering device for a truck disclosed in Chinese Patent CN216443533U, but this device has problems such as high manufacturing cost, complicated operation, and cannot be used in the case of an existing rain shelter on site, and needs to hang the tarpaulin first and then move the vehicle to achieve automatic tarpaulin covering. For example, Chinese Patent CN116968617A discloses an automatic tarpaulin covering device for a truck, but this device also has problems such as complicated components, complicated installation, and complicated operation when in use. CONTENT OF THE UTILITY MODEL

Detailed Implementation

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in specific embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0026] like Figure 1As shown, this application provides a device 100 (hereinafter referred to as "device 100") for automatically covering a target object with a flexible covering. The flexible covering can be a tarpaulin, abrasion-resistant fabric, sunshade cloth, or other coverings commonly referred to as tarpaulins. It can also be a protective film material used only for dust prevention, or a flexible net used to restrain goods or other target objects. The target object being covered can be a transport vehicle or a transport vehicle carrying goods, or stacked goods. In the following description, the automatic covering of a cargo truck with a tarpaulin will be used as an example for detailed explanation. Those skilled in the art should understand that the device in this application can also be applied to other flexible coverings for automatically covering target objects. The device 100 includes a guide rail mechanism 11, a drive mechanism 12, a traction mechanism 13, and a clamping mechanism 14. One end of the tarpaulin 200 is fixed to the device 100 by the clamping mechanism 14, and the device 100 can drive the tarpaulin 200 to move in the horizontal and vertical directions.

[0027] The guide rail mechanism 11 includes at least two guide rails 111 extending along a first direction. The two guide rails 111 are arranged parallel to each other. The guide rails 111 can be designed with an I-beam structure, possessing high load-bearing capacity and deformation resistance, ensuring that they can withstand the dynamic loads of components such as the drive mechanism 12 and the tarpaulin 200. The length of the guide rail 111 generally covers the maximum expected width of the truck 300 to meet the usage requirements of different truck models 300. The guide rail 111 typically has guide grooves or a rack structure, allowing the drive mechanism 12 to connect and move along the guide rail 111. This ensures that the drive mechanism 12 does not deviate from its trajectory during movement, while providing sufficient friction to overcome load inertia. Furthermore, the guide rail 111 can be installed on existing tarpaulin frames or roof beams, utilizing the existing operating environment to construct the device 100 for operation, adapting to actual production and reducing operating costs.

[0028] like Figure 2As shown, the drive mechanism 12 is used to move the device 100, including the device 100 driving the tarpaulin 200 to move horizontally and vertically. The drive mechanism 12 includes a first drive assembly 121, a second drive assembly 122, and a drive bracket 123. The first drive assembly 121 and the second drive assembly 122 are mounted on the drive bracket 123, with the first drive assembly 121 substantially above the second drive assembly 122. The first drive assembly 121 is slidably connected to the guide rail 111, enabling the drive mechanism 12 to move horizontally along the guide rail 111. The second drive assembly 122, driven by the first drive assembly 121, moves horizontally along the guide rail 111. The second drive assembly 122 can also move vertically up and down, enabling the device 100 to drive the tarpaulin 200 to move vertically up and down.

[0029] The traction mechanism 13 extends along a second direction that is substantially perpendicular to the first direction in the horizontal plane, meaning the extension direction of the traction mechanism 13 is substantially perpendicular to the extension direction of the guide rail 111. The upper part of the traction mechanism 13 is fixedly or detachably connected to the second drive member of the drive mechanism 12, increasing the structural flexibility of the device 100. The lower part of the traction mechanism 13 is connected to the clamping mechanism 14, which is used to fix the tarpaulin 200; one end of the tarpaulin 200 is fixed to the device 100 via the clamping mechanism 14. When the device 100 is working, under the action of the first drive assembly 121, the drive mechanism 12 moves on the guide rail 111 extending along the first direction. The drive mechanism 12 drives the traction mechanism 13 and the clamping mechanism 14 to move along the guide rail 111, thereby causing the tarpaulin 200 to move horizontally. The second drive assembly 122 performs a vertical lifting motion. Under the action of the second drive assembly 122, the traction mechanism 13 and the clamping mechanism 14 move vertically, thereby causing the tarpaulin 200 to move vertically.

[0030] The clamping mechanism 14 includes at least one clamping element 141 for clamping or hooking the tarpaulin 200. Optionally, the clamping mechanism 14 may include a plurality of clamping elements 141, which are distributedly connected to the traction mechanism 13 to improve the stability of clamping the tarpaulin 200. The plurality of clamping elements 141 may be evenly distributed and connected to the traction mechanism 13, or they may be distributed according to the spacing of the hanging holes of the tarpaulin 200 to improve the versatility of the device 100.

[0031] Before the device 100 operates, the target truck 300 is moved below the guide rail 111, with the truck 300 oriented substantially parallel to the extension direction of the traction mechanism 13. The device 100 is then activated. First, the second drive assembly 122 operates, driving the traction mechanism 13 and the clamping mechanism 14 to move vertically downwards. When the clamping mechanism 14 is moved to a position convenient for the operator, the second drive assembly 122 stops operating. The operator then secures one end of the tarpaulin 200 to the clamping mechanism 14. Subsequently, the second drive assembly 122 continues operating, driving the traction mechanism 13 and the clamping mechanism to move vertically upwards, gradually pulling one end of the tarpaulin 200 from the ground to a position convenient for covering the truck 300. At this point, the clamping mechanism 14 is higher than the top of the truck 300, and the second drive assembly 122 stops operating. Subsequently, the first drive assembly 121 operates, driving the traction mechanism 13 and the clamping mechanism 14 to move along the guide rail 111 to the other side, moving one end of the tarpaulin 200 from one side of the truck 300 to the opposite side, gradually covering the truck 300 with the tarpaulin 200. The first drive assembly 121 then pauses operation, while the second drive assembly 122 continues, driving the traction mechanism 13 and the clamping mechanism 14 vertically downwards. When the clamping mechanism 14 is moved to a position convenient for the operator, the operator removes one end of the tarpaulin 200 from it. The second drive assembly 122 then drives the traction mechanism 13 and the clamping mechanism 14 vertically upwards, completing the automatic tarpaulin 200 covering of the truck 300.

[0032] Based on the above description, the device 100 for automatically covering flexible coverings provided in this application, through the coordinated operation of the guide rail mechanism 11, drive mechanism 12, traction mechanism 13, and clamping mechanism 14, can automatically cover objects such as trucks 300 with flexible coverings without manual operation on the roof, avoiding the safety risks of workers trampling on the products and climbing the roof. The guide rail 111 of the device 100 for automatically covering flexible coverings provided in this application can be installed on existing awning frames or roof beams, etc., utilizing the existing operating environment to build the device 100 for operation, adapting to actual production, simplifying the device, reducing operating costs, and facilitating operation.

[0033] As one implementation method, such as Figure 3As shown, the first drive assembly 121 includes a first motor 1211, a driving wheel 1212, and a driven wheel 1213. The first motor 1211, driving wheel 1212, and driven wheel 1213 are all mounted on a drive bracket 123. The first motor 1211 is drive-connected to the driving wheel 1212, which is slidably connected to one side of the guide rail 111. The driven wheel 1213 is slidably connected to the opposite side of the guide rail 111. The first motor 1211 drives the driving wheel 1212 to rotate, causing the driving wheel 1212 to move along the guide rail 111. As the driving wheel 1212 moves, it drives the driven wheel 1213 to rotate, thereby enabling the drive mechanism 12 to move along the guide rail 111. Figure 3 The driving wheel 1212 and the driven wheel 1213 shown are respectively disposed on the left and right sides of the guide rail 111. Optionally, the positional relationship between the driving wheel 121, the driven wheel 1213 and the guide rail 111 can be changed, and the driving wheel 1212 and the driven wheel 1213 can be disposed on the upper and lower sides of the guide rail 111 respectively.

[0034] As one implementation method, such as Figure 3 As shown, the second drive assembly 122 includes a second motor 1221 and a lifting member 1222. The second motor 1221 is driven to the lifting member 1222. The lifting member 1222 can be configured to be fixedly connected to the traction mechanism 13, or it can be configured to be detachably connected to the traction mechanism 13. The second motor 1221 controls the lifting member 1222 to move vertically, and the traction mechanism 13 follows the lifting member 1222 to move vertically. Further, the lifting member 1222 includes one of a chain, gear, belt, or cable. The second drive assembly 122 may also include a storage box 1223 for accommodating or carrying the lifting member, including the chain, belt, and cable. For example, taking the lifting member 1222 as a chain, the second motor 1221 is driven to the lifting member 1222 via a chain. When the second motor 1221 starts, it controls the lifting member 1222 to move downwards vertically, and the chain in the storage box 1223 is gradually pulled out. When the clamping mechanism 14 moves to a position convenient for the operator, the second motor 1221 stops working, and the operator secures one end of the tarpaulin 200 to the clamping mechanism 14. Then, the second motor 1221 restarts, controlling the lifting component 1222 to move vertically upwards. The lifting component 1222 is moved vertically upwards via a chain, with part of the chain being stored back into the storage box 1223, until the tarpaulin 200 is pulled up to a position convenient for covering the truck 300. At this point, the second motor 1221 stops working.

[0035] As one implementation method, such as Figure 4 As shown, the drive mechanism 12 also includes a control unit 124, which includes a power supply module 1241, a drive module 1242, and a communication module 1243. Figure 5As shown, the power supply module 1241 is electrically connected to the drive module 1242, the drive module 1242 is electrically connected to the first drive component 121 and the second drive component 122, and the communication module 1243 is electrically connected to the drive module 1242. The communication module 1243 is used to receive external control signals, and based on the external control signals, the drive module 1242 controls the first drive component 121 and the second drive component 122 to perform corresponding actions, thereby performing the automatic tarpaulin covering 200 operation. Optionally, a preset control program can also be used to control the device 100. The communication module 1243 receives the action signals issued by the program, and the drive mechanism 12 controls the first drive component 121 and the second drive component 122 to perform corresponding actions according to the action signals, thereby performing the automatic tarpaulin covering 200 operation.

[0036] In one implementation, the traction mechanism 13 has a length of 6m to 20m in the second direction. The traction mechanism 13 is configured as a long strip, and its length covers the length of most trucks 300 to meet the needs of automatically covering various trucks 300 with tarpaulins 200. Optionally, the traction mechanism 13 can be modularly designed to improve the structural flexibility of the device 100 to adapt to different working environments.

[0037] Furthermore, the traction mechanism 13 is made of aluminum alloy profiles. Aluminum alloy profiles can reduce the weight of the traction mechanism 13 while maintaining its strength, thereby reducing the energy consumption of the automatic tarpaulin cover device 100 and improving its safety. Alternatively, the traction mechanism 13 can be made of steel trusses. Steel trusses are typically constructed from angle steel, channel steel, or H-beams through welding or bolting. Their truss structure, through the repeated arrangement of triangular or rectangular units, achieves high rigidity and high bending resistance for the traction mechanism 13. Steel trusses have high structural redundancy; by rationally designing nodes and support points, the coverage length of the traction mechanism 13 can be extended to meet the installation requirements of extra-long trucks or fixed awnings.

[0038] In one implementation, the clamping mechanism 14 is slidably connected to the traction mechanism 13. The position of the clamping mechanism 14 can be flexibly adjusted, improving its applicability to the tarpaulin 200 and enhancing the versatility of the device 100. The clamping mechanism 14 includes at least one of a fixing hook or a fixing clip, or the clamping mechanism 14 includes at least two fixing hooks and a fixing clip connected to some of the fixing hooks. The fixing hooks are suitable for tarpaulins 200 with hanging holes, while the fixing clips are suitable for tarpaulins 200 without hanging holes. The fixing clips have hanging rings for connecting to the fixing hooks. The mixed use of fixing clips and fixing hooks can accommodate various tarpaulins 200, enhancing the flexibility of the device 100. Furthermore, the fixing hooks or fixing clips are slidably connected to the traction mechanism 13, and the position of the fixing hooks or fixing clips can be adjusted according to the hole spacing of the hanging holes of the tarpaulin 200, further enhancing the flexibility of the device 100.

[0039] As a more specific implementation, the device 100 includes a set of guide rail mechanisms 11, two sets of drive mechanisms 12, and a traction mechanism 13. The guide rail mechanism 11 includes two parallel guide rails 111. Each set of drive mechanisms 12 is connected to one guide rail 111. One end of the traction mechanism 13 is connected to the bottom of one set of drive mechanisms 12, and the other end of the traction mechanism 13 is connected to the bottom of the other set of drive mechanisms 12. Figure 6 As shown, the target truck 300 is parked under the device 100. The width direction of the truck 300 is basically parallel to the extension direction of the guide rail 111. Through the modular design of the traction mechanism 13, the length of the traction mechanism 13 can be flexibly adjusted. The length of the traction mechanism 13 is greater than or equal to the length of the truck 300 to facilitate the automatic covering of the truck 300 with the tarpaulin 200. The device 100 also includes a clamping mechanism 14, which includes a plurality of clamping elements 141 to improve the stability of clamping the tarpaulin 200.

[0040] As one implementation method, such as Figure 7 As shown, the device 100 also includes a movable base 15, with both ends of the guide rail 111 connected to the top of the base 15. The device 100 can be moved via the base 15, enabling flexible deployment and adjustment of the device 100, suitable for temporary operation scenarios or scenarios requiring frequent changes in covering positions. For example, when covering tall products that require film packaging with a tarpaulin 200 or protective film, the device 100 can be pushed above the target object to automatically cover it with the tarpaulin 200 or protective film.

[0041] Based on the above description, the device 100 for automatically covering flexible coverings provided in this application, through the coordinated operation of the guide rail mechanism 11, drive mechanism 12, traction mechanism 13, and clamping mechanism 14, realizes the automatic covering of flexible coverings on objects such as trucks 300, eliminating the need for manual operation on the roof and avoiding the safety risks of workers trampling on the products and climbing the roof. The guide rail 111 of the device 100 for automatically covering flexible coverings provided in this application can be installed on existing structures such as awning frames or roof beams, utilizing the existing operating environment to build the device 100 for operation, adapting to actual production, simplifying the device, reducing operating costs, and facilitating operation. The device 100 for automatically covering flexible coverings provided in this application also achieves flexible adjustment of the traction mechanism 13 and clamping mechanism 14 through modular design, improving the applicability of the device 100.
