[0052] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0053] Various aspects and features of the present application are described herein with reference to the accompanying drawings.

[0054] These and other characteristics of the present application will become apparent from the following description of a preferred form of embodiment given as a non-limiting example with reference to the accompanying drawings.

[0055] It should also be understood that although the present application has been described with reference to certain specific examples, those skilled in the art will be able to implement many other equivalent forms of the present application that have the features described in the claims and are therefore within the scope of protection defined thereby.

[0056] The above and other aspects, features and advantages of the present application will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0057] Specific embodiments of the present application will be described below with reference to the accompanying drawings; however, it should be understood that the embodiments described are merely examples of the present application and may be implemented in a variety of ways. Familiar and / or repetitive functions and structures are not described in detail to clarify the true intent based on the user's historical operations and to avoid obscuring the present application with unnecessary or redundant details. Therefore, the specific structural and functional details described herein are not intended to be limiting, but rather serve merely as a basis and representative basis for the claims to teach those skilled in the art to use the present application in a variety of ways with substantially any appropriate detailed structure.

[0058] This specification may use the phrases "in one embodiment," "in another embodiment," "in a further embodiment," or "in other embodiments," which may all refer to one or more of the same or different embodiments according to the present application.

[0059] In the prior art, a special paving vehicle is mostly used to achieve the purpose of paving roads. However, this type of equipment is an additional special equipment in actual projects. In actual situations, there is often no special equipment equipped with this type of equipment, but loaders are generally used for projects. Therefore, the present invention wants to use a loader to achieve paving work.

[0060] While both approaches can address the access problem, Technical Approach 1 relies on manual labor, resulting in low efficiency and high labor intensity. Technical Approach 2, while highly efficient, relies on specialized paving vehicles, but is also costly and requires the installation of paving and removal vehicles. Neither approach can quickly and cost-effectively address the issue of ensuring the passage of heavy equipment on low-load roads.

[0061] The present invention proposes a multifunctional hard pavement paving and removal equipment. The equipment uses a loader as a carrier. The loader can clear larger obstacles on the road surface. On soft foundation roads, the loader bucket can be replaced with a road paving device, so that the loader has a road paving function. Only manual assistance is required for operation, which solves the problem of high labor intensity in road paving. At the same time, mechanized installation is adopted, and the operation time is shorter than manual operation time, and the efficiency is higher, thereby improving the emergency guarantee effectiveness of the road surface.

[0063] like Figures 1 to 14 As shown, in one embodiment, the present invention provides a pavement paving and withdrawing equipment, the pavement paving and withdrawing equipment comprising a loader, a paving and withdrawing device, and a pavement assembly;

[0064] The loader 1 has a mechanical arm 11 that can rotate along a fixed point to achieve the lifting and lowering of the mechanical arm 11. The loader 1 adopts a product commonly used in engineering machinery. An 8t loader can be selected according to the applicable paving length.

[0065] The laying and withdrawing device 2 is connected to the lifting end of the mechanical arm 11;

[0066] The pavement assembly 3 is mounted on the paving and withdrawing device 2 , and the reel 4 is carried on the pavement assembly 3 , so that when the mechanical arm 11 is lifted, the pavement assembly 3 tilts to form a slope, so that the reel 4 can be unfolded.

[0067] This embodiment provides a specific structure of a road paving and removal device. This device utilizes a loader 1 as a carrier, capable of clearing larger obstacles on the road surface. On soft surfaces, the loader's bucket can be replaced with a road paving device, namely, a paving and removal device 2, enabling the loader to perform road paving operations. This allows only manual assistance and control, resolving the labor-intensive nature of road paving. Furthermore, the mechanized installation process shortens the operation time compared to manual work, resulting in higher efficiency and improved road emergency response capabilities. This helps address the technical issue of limited versatility of equipment used in existing technologies for paving softer surfaces.

[0068] The paving and withdrawing device 2 is installed after the bucket of the loader 1 is removed. The connection method of the paving and withdrawing device 2 is the same as that of the bucket, ensuring smooth connection between the paving and withdrawing device 2 and the main body of the loader 1. The hydraulic power of the paving and withdrawing device 2 is provided by the loader. Both ends of the paving and withdrawing device 2 can be quickly connected to the road reel.

[0069] It should be noted that the reel 4 has a rolled paving piece that is flexible and can be unrolled along its length. The reel 4 here is prior art, and its structure and function will not be further described in detail. The essence of the present invention is to use the loader 1, which is basically used in engineering projects, in conjunction with the paving and removal device 2 and the road surface assembly 3 to complete the paving task. Regardless of whether the road surface is a soft foundation road surface or a road surface with obstacles, the present invention uses the loader's bulldozer to perform obstacle removal operations on the road surface with obstacles to ensure road access; on the soft foundation bearing road surface, the bulldozer is disassembled and replaced with the road paving device, and the loader is converted into a road paving and removal vehicle to pave a temporary passage to ensure the passage of heavy equipment or vehicles.

[0070] Furthermore, the present invention's loader-based pavement paving process requires designers to consider the balance and stability of the loader's paving process, as well as its compatibility with the loader. The designers must consider the loader's curb weight, the pavement width and length, the type of pavement drum, the compatibility of the paving and retracting device with the interface of different loader models, and the balance and stability of the paving process. To ensure paving stability, the paving and retracting device and pavement drum were optimized for lightweight construction while maintaining the required pavement length.

[0071] The road surface assembly 3 is quickly assembled with the drum therein, and paving is achieved by rotating the drum.

[0072] In one embodiment, the pavement laying and withdrawing equipment further includes pavement mooring cables 5 on both sides;

[0073] One end of the road mooring cable is connected to one side of the drum after laying, and the other end of the road mooring cable is connected to the ground.

[0074] In this embodiment, a specific implementation method of how to connect the road mooring cable 5 is provided.

[0075] In one embodiment, the road mooring cables are spaced at intervals of 20 meters.

[0076] In one embodiment, the paving and retracting device includes a hydraulic motor assembly for laying the paving roll.

[0077] In one embodiment, a road surface assembly quick device is provided on the road surface assembly to fix the reel to be expanded or retracted.

[0078] In one embodiment, the road assembly quick device 6 is provided with a semicircular groove 61;

[0079] The groove 61 is padded with a cylinder 62 arranged along the length direction of the groove 61;

[0080] The road assembly quick device 6 is further provided with a bolt 63 so that the threaded end of the bolt 63 can support the reel 4 .

[0081] The paving and retracting device 2 is primarily used to wind up the pavement assembly 3, quickly connect to the loader 1, and complete the pavement paving and retracting operations. The paving device is installed after the loader 1 removes the bucket. Its mechanical connection interface is identical to that of the bulldozer, ensuring smooth connection to the loader 1. Hydraulic power for the paving device is provided by the loader. The paving and retracting device features a connector for connecting to the pavement assembly reel, enabling quick and reliable connection and disconnection with the reel.

[0082] In one embodiment, the paving and retracting device 2 is hingedly connected to the robotic arm via a single- and double-ear hinge and a hinge shaft. The paving and retracting device 2 primarily consists of a paving device structure 4, a hydraulic motor assembly 5, and a road surface assembly quick-connect mount 6. Before paving, the loader 1 can be used to clear obstacles on the road. During paving, the dozer blade of the loader 1 is removed and the paving and retracting device 2 is installed and secured.

[0083] The road assembly 3 and the paving and retracting device 2 are fixedly connected via V-shaped slots and latches at both ends, enabling quick connection and disconnection. The pins in the hydraulic motor assembly 5 on the paving and retracting device 2 are securely connected to the pin wheel on the reel in the road assembly 3 for transmission. The hydraulic power of the motor is provided by the loader 1.

[0084] In one embodiment, the road mooring cables are arranged in groups of four, extending from a central portion to four corners, and the obtuse angle with the horizontal direction is 150 to 180 degrees.

[0085] In one embodiment, the laying and withdrawing device is connected and fixed to the robotic arm via two fixing points.

[0086] In one embodiment, the present invention further provides a paving method using a pavement paving and withdrawing device. Based on the pavement paving and withdrawing device, the paving method using the pavement paving and withdrawing device includes:

[0087] Lowering the raised robotic arm 11 to a predetermined height;

[0088] The reel 4 is released to release the paving pieces 41 one by one downwards through the slope formed by the reel 4. When paving the road, the vehicle moves forward, driving the road surface to be pulled out from the reel to the ground. During the paving process, the angle is adjusted to avoid interference between the unit plate and the paving device.

[0089] During this paving method, the tires of the loader 1 will continuously press on the released paving members during the release process. The paving members are a rolled-up flexible blanket structure, specifically a strip structure arranged in the length direction and connected by flexible connecting members.

[0090] In addition, when the robotic arm 11 is tilted to a certain angle, the laying and withdrawing device 2 will automatically pick up the flexible carpet structure.

[0091] Beneficial effects:

[0092] The present invention provides a multifunctional hard pavement laying and removal system. Using a loader as a carrier, the system lays and removes pavement, creating a temporary movable pavement that allows for the passage of vehicles and equipment. The loader can be used for pre-paving road clearance and also serves as a multifunctional carrier and power source for paving. This invention eliminates the need for dedicated paving and removal vehicles, making it more economical. The mechanized paving process, powered by a loader, reduces labor intensity. The loader, paving and removal device, and pavement assembly utilize a quick-disassembly design, enhancing the maneuverability, flexibility, and convenience of paving.

[0093] Regardless of whether the road surface is a soft foundation road surface or a road surface with obstacles, the multifunctional hard road paving and withdrawing equipment of the present invention can ensure the passage of heavy-loaded equipment or vehicles. On roads with obstacles, the bulldozer of the loader is used to perform obstacle removal operations to ensure the passage of the road; on soft foundation bearing roads, the bulldozer is disassembled and replaced with a road paving device, and the loader is converted into a road paving and withdrawing vehicle to pave a temporary passage to ensure the passage of heavy equipment or vehicles. The multifunctional hard road paving and withdrawing equipment of the present invention includes a loader, a paving and withdrawing device, a road surface assembly, etc. The difficulty of the design is the balance stability of the road paving with the loader as the carrier and the matching degree with the loader. The designer needs to coordinate the curb weight of the loader, the width and length of the road surface, the type of the road surface drum, the adaptation of the paving and withdrawing device to the interface of different types of loaders, and the balance stability of the paving process. In order to ensure the stability of the paving process, the paving and withdrawing device and the road surface drum are optimized for lightweight structure under the condition of meeting the paving road length.

[0094] The paving and retracting device is primarily used to wind up the pavement assembly, quickly connect to the loader, and complete the pavement paving and retracting operations. The paving device is installed after the loader bucket is removed. Its mechanical connection interface is identical to that of the dozer blade, ensuring smooth connection to the loader body. The loader provides hydraulic power for the paving device. The paving and retracting device features a connector that connects to the pavement assembly reel, ensuring quick and reliable connection and disconnection with the reel.

[0095] The multifunctional hard pavement paving and retrieving equipment of the present invention comprises a loader, a paving and retrieving device, and a pavement assembly. The loader is used to carry and install the paving and retrieving device, provide power and electricity for the equipment, and transport the operating mechanism and pavement assembly. The loader itself can also be used to clear obstacles before paving. The paving and retrieving device is primarily used to wind up the pavement assembly and is connected to the loader body. The pavement assembly is the core component that enables the equipment's functionality and meets the road's load-carrying requirements.

[0096] The loader is a product commonly used in engineering machinery. An 8t loader can be selected according to the appropriate paving length.

[0097] The paving and withdrawing device mainly consists of a paving device structure, a hydraulic motor assembly, and a pavement assembly quick connection seat.

[0098] The pavement assembly primarily consists of a drum and pavement surface. The pavement surface primarily comprises standard unit panels, connecting pins, and bolts. Moorings are installed at the ends of the pavement section and every 20 meters. The pavement surface can be quickly separated and connected at the joints between the two unit panels as needed to accommodate varying paving lengths.

[0099] The paving and retracting device is integrated with the loader via a single- and double-ear hinge and a hinge shaft, enabling reliable connection and separation. Before paving, the loader can be used to clear obstacles on the road. During paving, the loader's dozer blade is removed and the paving and retracting device is installed.

[0100] The road surface assembly and the paving and retracting device are fixedly connected via V-shaped slots and latches at both ends, enabling quick connection and disconnection. The pinion gear in the hydraulic motor assembly on the paving and retracting device reliably connects with the pin wheel on the reel in the road surface assembly for transmission. The motor's hydraulic power is provided by the loader.

[0101] The multifunctional hard pavement paving and removal equipment of the present invention comprises a loader, a paving and removal device, and a pavement assembly.

[0102] The paving and retracting device is installed after the loader bucket is removed. The connection method for the paving and retracting device is the same as that for the bucket, ensuring smooth connection between the paving and retracting device and the loader body. The hydraulic power for the paving and retracting device is provided by the loader. Both ends of the paving and retracting device can be quickly connected to the road reel.
