Description

Technical Field

[0001] This invention relates to the field of civil engineering construction equipment technology, and in particular to a roll material laying device and method. Background Technology

[0002] In current civil engineering projects, especially in road, water conservancy, and environmental protection projects, flexible roll materials such as geotextiles and composite waterproof geotextiles are widely used. These roll materials, especially those without a rigid supporting core, are soft in nature and prone to bending and folding in the width direction.

[0003] Current standard construction methods typically require at least two workers to work together. Each worker is positioned at one end of the roll width, bending over and using their hands or simple tools to push the roll forward in unison to lay it. This method requires two workers, resulting in high labor demands and slow laying speed due to the coordination between the workers. Workers also have to work in a bent-over position for extended periods, putting significant strain on their lumbar spine and increasing the risk of occupational fatigue and injury. Manual pushing makes it difficult to maintain uniform tension during laying, easily leading to wrinkling, folding, or skewing of the roll, affecting project quality. On uneven or sloping surfaces, workers focused on pushing the material may neglect their surroundings, posing safety hazards.

[0004] Therefore, there is an urgent need to design a technical solution that enables a single person to efficiently lay flexible roll materials. Summary of the Invention

[0008] Preferably, the follow-up pressing mechanism includes a connecting frame and pressing rollers. The connecting frame is connected to both ends of the receiving chamber. The pressing rollers are movably mounted on the connecting frame. The pressing rollers can abut against the upper surface of the flexible roll material extending from the strip opening for laying operations, and rely on gravity to press and adhere the flexible roll material to the working surface during the laying process.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] The purpose of this invention is to provide a roll material laying device and method to solve the problems existing in the prior art, enabling a single person to efficiently lay flexible roll materials.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Current methods for laying roll-type roofing membranes typically require at least two workers working together. Each worker is positioned at one end of the roll's width, bending over and simultaneously pushing the roll forward with their hands or simple tools to unfold it. This method demands a large workforce, and the laying speed is limited by the coordination of the workers, resulting in low overall efficiency. Workers also have to bend over for extended periods, putting significant strain on their lumbar spine and easily leading to occupational fatigue and injury. Furthermore, manual pushing makes it difficult to ensure uniform tension during laying, easily causing the roll to wrinkle, fold, or skew, affecting project quality. To address these problems, this invention provides a roll-type roofing membrane laying device, such as... Figure 1 , Figure 2 , Figure 3 As shown, the invention includes a receiving chamber 1, a traction mechanism 7, and a traveling mechanism. The receiving chamber 1 is used to hold rolled flexible sheet material 8. A strip-shaped opening 4 is provided on one side of the receiving chamber 1, through which the end of the flexible sheet material 8 can extend for laying. The traveling mechanism is located at the bottom of the receiving chamber 1 and can drive the receiving chamber 1 to move horizontally. The traction mechanism 7 is connected to the side of the receiving chamber 1 away from the strip-shaped opening 4 and can be connected to external traction equipment to move the receiving chamber 1. This invention transforms traditional two-person or multi-person operations into single-person or mechanized operations, halving labor costs. The speed of mechanized dragging and laying is much higher than that of manual labor, increasing efficiency by at least 100%. Operators only need to stand and pull or drive the mechanical equipment to pull, eliminating the need for frequent bending over, greatly improving work comfort and reducing occupational health risks. The receiving chamber 1, together with its strip-shaped opening 4, provides a stable unfolding platform for the sheet material. The strip-shaped opening 4 guides and flattens the sheet material, resulting in a flat, wrinkle-free sheet material with uniform tension. With its simple overall structure, ease of processing and manufacturing, and low material and production costs, it is suitable for widespread use in various engineering projects. It is particularly suitable for laying various geotextiles and waterproof membranes that lack a rigid inner core and are inherently soft and easily foldable, thus solving a key industry pain point.

[0024] In one embodiment, the traction mechanism 7 includes a handle and two traction rods. The two traction rods are arranged symmetrically and obliquely, with one end of each traction rod fixedly connected to the receiving compartment 1 and the other end connected to a horizontally arranged handle. The handle is T-shaped or ring-shaped, allowing for connection to external traction equipment such as vehicles, or manual gripping of the handle for traction operations. This design ensures that the pulling force is evenly applied to the entire device, facilitating stable dragging and directional control by a single person or machine (vehicle).

[0025] Because the roll material is flexible, it is prone to suspension or wrinkling during the laying process. To solve the problem of the flexible roll material 8 being lifted off the ground due to tension during the dragging process, a follow-up pressing mechanism 9 is designed in one embodiment. It is movably connected to the receiving chamber 1, and the follow-up pressing mechanism 9 and the strip opening 4 are located on the same side of the receiving chamber 1. The follow-up pressing mechanism 9 can abut against the upper surface of the flexible roll material 8 extending from the strip opening 4 for the laying operation, so as to press and adhere the flexible roll material 8 to the working surface during the laying process. The follow-up pressing mechanism 9 ensures that the roll material is compacted and adhered to the ground at the moment of laying, solving the problem of the roll material being suspended and wrinkled in the traditional traction laying method, and the laying effect is flat and compact.

[0026] The structure of the follow-up covering mechanism is not limited. It can be a covering plate located on one side of the receiving chamber 1, with the covering plate arranged close to the laying surface. The roll material during the laying process is located between the laying surface and the covering plate, and the covering plate flattens the roll material during the laying process. In another embodiment, the follow-up covering mechanism 9 includes a connecting frame 901 and a covering roller 902. The connecting frame 901 is movably connected to both ends of the receiving chamber 1. The covering roller 902 is movably mounted on the connecting frame 901. The covering roller 902 can abut against the upper surface of the flexible roll material 8 extending from the strip opening 4 for the laying operation, and rely on gravity to cover and adhere the flexible roll material 8 to the working surface during the laying process, ensuring that the roll material is compacted and adhered to the ground at the moment of laying.

[0027] In one embodiment, the receiving chamber 1 is a hollow cylindrical structure with a strip-shaped opening 4 on one side arranged along the axial direction of the receiving chamber 1. The receiving chamber 1 includes an upper shell 101 and a lower shell 102. The upper shell 101 and the lower shell 102 can be made of lightweight, high-strength thin steel plates or engineering plastics. The opening ends of the upper shell 101 and the lower shell 102 are joined together to form this cylindrical structure. One side of the upper shell 101 is connected to one side of the lower shell 102 by a hinge 2, and the other side of the upper shell 101 is connected to the other side of the lower shell 102 by a latch 3. Opening the latch 3 allows the upper shell 101 to open around the hinge 2, so that a roll of flexible material 8 can be placed in the receiving chamber 1. After the upper shell 101 is fastened and locked with the lower shell 102 by the latch 3, it can be ensured that the roll of material will not fall out of the receiving chamber 1. In order to improve the protective effect, in one embodiment, side covers are provided at both ends of the receiving chamber 1 along the axial direction to protect the internal space of the receiving chamber 1.

[0028] In one embodiment, a drag-reducing mechanism is provided inside the receiving chamber 1. The drag-reducing mechanism includes driven rollers 5 parallel to the axis of the receiving chamber 1. The bottom of the receiving chamber 1 is provided with multiple rows of wheel sets arranged along the circumference of the receiving chamber 1. Each row of wheel sets includes multiple driven rollers 5 arranged in an array along the axial direction of the receiving chamber 1. The driven rollers 5 are rotatably connected to the inner sidewall of the receiving chamber 1, which facilitates the reduction of friction caused by the weight and dragging of the flexible roll material 8 inside the receiving chamber 1. In this embodiment, a driven roller 5 is provided on the inner side of the upper edge and the inner side of the lower edge of the strip opening 4. When the flexible roll material 8 is dragged outward, the contact between it and the receiving chamber 1 changes from sliding friction to rolling friction, which greatly reduces the discharge resistance and ensures the smoothness of the pull-out.

[0029] In one embodiment, the walking mechanism includes a plurality of walking wheels 6 located at the bottom of the outer side of the receiving compartment 1. The walking wheels 6 are large in size to adapt to uneven construction site ground.

[0030] The present invention also provides a method for laying roll materials using the above-mentioned roll material laying device, comprising the following steps: Before use, first unlock the latch 3 and open the upper shell 101 through the hinge 2 to form an open cavity. Place a whole roll of flexible material 8 (such as geotextile) into the lower shell 102. Then, fasten the upper shell 101 onto the lower shell 102 and lock it with the latch 3, so that the receiving compartment 1 completely wraps the flexible material 8.

[0031] Pull a section of the end of the flexible roll 8 out of the slot 4.

[0032] like Figure 3 As shown, the operator holds the handle of the traction mechanism 7 or uses a vehicle to pull the entire device forward. Supported by the external wheels 6, the device rolls forward along the ground. Under the pulling force, the flexible roll 8 is continuously pulled out through the slot 4. During the extraction process, the main body of the flexible roll 8 rolls within the receiving chamber 1, and its outer surface contacts the drag-reducing rollers on the inner wall of the receiving chamber 1. These drag-reducing rollers transform the sliding friction between the flexible roll 8 and the chamber wall into rolling friction, allowing the flexible roll 8 to be smoothly extracted with minimal resistance and flatly laid on the ground. The entire process can be completed by a single person in a standing or walking posture, making it easy and effortless. If a vehicle is used for towing, the efficiency is even higher.

Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope.
