Description

Technical Field

[0001] This invention relates to the field of roof construction technology, and in particular to a roof roll installation device. Background Technology

[0002] In building construction, roof waterproofing is a crucial step in ensuring structural safety and energy supply, directly impacting the building's lifespan and occupant comfort. Among roof waterproofing methods, rolled roofing membrane installation is one of the most widely used due to its reliable waterproofing performance and mature construction techniques. The areas covered by rolled roofing membrane installation include the horizontal roof surface, the junctions of parapet walls and other side walls with the horizontal surface, and roof corners and transitions, among other complex locations. The required installation direction and angle vary significantly across these areas, placing high demands on the adaptability and flexibility of the installation equipment.

[0003] Currently, roof roll material installation equipment is mainly manual-assisted, simple equipment, consisting primarily of a frame, material roller brackets, and guide rollers. Installation is achieved by manually pulling the roll material and pushing the equipment. However, the material box and guide roller assembly are in fixed positions, allowing only unidirectional planar installation. When vertical installation is required at the junction of the sidewall and the horizontal plane, the guide roller assembly must be disassembled, the material box angle readjusted, or even specialized vertical installation equipment may need to be replaced. This process is cumbersome, time-consuming, and labor-intensive, severely impacting construction progress.

[0004] To address the aforementioned shortcomings, this invention optimizes the overall structural design of the equipment and employs core technologies such as a material box side-bias adjustment mechanism, a roller group linkage adaptation structure, and a precise positioning mechanism. This provides a roof roll material installation device that can flexibly switch between horizontal and vertical planes, solving the problem of poor adaptability of traditional equipment. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art and to propose a roof roll installation device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A roofing roll material laying device includes a frame with a movable frame that slides left and right on the frame. The movable frame has a side-biased material box for holding the roll material. The left side of the movable frame has a fixed roller group one and a fixed roller group two, and the right side of the material box has a movable roller group one and a movable roller group two. The pulling end of the roll material passes through the fixed roller group one and the movable roller group one simultaneously, and then passes through the fixed roller group two and the movable roller group two simultaneously. The movable roller group one tilts to the side synchronously with the material box, and the movable roller group two rotates 90° synchronously with the side-biasing of the material box.

[0007] Preferably, the upper end of the movable frame is provided with an arc-shaped support, and the lower end of the material box is provided with an arc-shaped arch frame. The arch frame matches the support, and the lower end face of the arch frame is provided with two sets of sliders. The support is provided with a groove for the sliders to pass through. The ends of the two sets of sliders after passing through the groove are connected to a connecting plate. The connecting plate is detachably connected to the two sets of sliders.

[0008] Preferably, the movable frame is provided with a reversing roller near the axis of the vehicle frame, and a pull rope is connected to one end of the bottom of the arch frame. The other end of the pull rope is wrapped around the reversing roller and connected to the vehicle frame. Both ends of the pull rope are on the same side.

[0009] Preferably, the frame is U-shaped, with two sets of guide rails inside the frame, and a rail sleeve that slides with the two sets of guide rails on the movable frame. The rail sleeve has a screw hole, and a positioning bolt is screwed into the screw hole. The guide rails have positioning holes at the beginning and end of the movable frame's travel for the positioning bolt to be inserted.

[0010] Preferably, the lower ends of the two sets of rail sleeves on the front side of the movable frame are connected to a mounting plate. A rotating shaft is rotatably mounted on the mounting plate. A gear is fixed at one end of the rotating shaft, and the gear meshes with a rack fixedly mounted on the frame. An L-shaped side frame is fixedly mounted at the other end of the rotating shaft, and the second set of movable rollers is set on the side frame.

[0011] Preferably, the right end of the fixed roller group two is embedded with a head hammer, the end of which is chamfered, and the left end of the movable roller group two is embedded with a telescopic shaft. The telescopic shaft is provided with a straight groove frame at the end facing the head hammer, and the end of the head hammer facing the straight groove frame is provided with an insertion port for inserting the straight groove frame. The insertion port is provided with a rod for inserting into the straight groove frame.

[0012] Preferably, a movable plate is fixedly installed on the front side of the arch frame, and a set of movable rollers is arranged on the movable plate.

[0013] Preferably, one end of the movable roller group facing the fixed roller group is hemispherical.

[0014] Preferably, the material box includes a box body and a box lid. The rear end of the box body is arc-shaped, and the upper end of the box body is provided with a notch for the box lid to fit into. The contact surface between the back side of the box body and the box lid is a wedge-shaped surface. Both ends of the box body are rotatably mounted with swing rods. The ends of the swing rods are open, and connecting blocks are slidably mounted in the openings. A tension spring is provided between the connecting blocks and the bottom wall of the openings. Multiple connecting claws are provided on the connecting blocks, and the connecting claws are connected to the ends of the box lids.

[0015] Preferably, both the front interface of the box body and the box cover are rotatably mounted with rotating rollers.

[0016] Compared with the prior art, the present invention provides a roof roll material installation device, which has the following beneficial effects: 1. This invention, through the side-biasing adjustment of the material box and the coordinated adaptation of movable roller group one and movable roller group two, enables rapid conversion between horizontal and vertical paving without disassembling the equipment or replacing parts. The operation process is simple and easy to understand, and construction personnel can operate it proficiently after simple training. At the same time, the linkage structure of the equipment reduces manual adjustment steps and lowers the labor intensity of construction personnel.

[0017] 2. In this invention, all four sets of rollers employ a symmetrical clamping structure with two sets of rotating rollers, forming a double-sided guiding and limiting mechanism for the roll material, effectively preventing lateral deviation and wrinkling during the roll material pulling process. Simultaneously, the first movable roller set tilts laterally with the material box, guiding the roll material bending in advance. Then, the second movable roller set rotates 90° to drive the subsequent right-angle bending of the roll material. This transitional change in the roll material can reduce some torsional stress and minimize unevenness in the roll material installation.

[0018] 3. This invention uses a movable frame to form an integrated linkage operation, synchronously controlling the pilot bending and subsequent bending operations of the roll material. It has a simple structure and is easy to operate.

[0019] 4. In this invention, a hammer is embedded in the right end of the fixed roller group two, and a telescopic shaft is embedded in the left end of the movable roller group two. One end of the telescopic shaft is provided with a straight groove frame, and one end of the hammer is provided with a rod inserted into the straight groove frame. When the material box is tilted to the side, the movable roller group two rotates with the side frame, driving the telescopic shaft and the straight groove frame to rotate synchronously. Since the straight groove frame and the hammer are connected by the rod, in the initial stage of rotation, the rod moves within the straight groove of the straight groove frame to adjust the movement gap. At the same time, the hammer is pulled out of the fixed roller group two, and the horizontal length of the fixed roller group two extends, tending to abut against the bend at the joint with the ground side wall, that is, against the area where the roll material needs to be bent at 90°. It forms a tight clamping structure in the vertical direction with the fixed roller group two and the movable roller group two, cooperating with each other to provide a stable limiting top pressure for the roll material bending, assisting the roll material to bend at 90° and bend shaping, and reducing the problems of loosening and displacement during vertical laying.

[0020] 5. The material box design of this invention facilitates the loading and unloading of the roll material, prevents the roll material from shifting, and even if it shifts, it will not affect the stability of the roll material after unwinding and extending.

[0021] 6. In this invention, one end of the movable roller assembly facing the fixed roller assembly is hemispherical, and the surface of the hemispherical end is polished, making it smooth and burr-free. Compared with the right-angle end, the hemispherical end has a larger contact area with the roll material and disperses stress. For thicker roll materials, the curved contact of the hemispherical end can effectively disperse pressure and prevent the roll material from being excessively squeezed; for thinner roll materials, the gentle contact of the hemispherical end can prevent the roll material from being scratched or torn, thus improving the adaptability of the equipment to roll materials of different specifications.

[0022] Other advantages, objectives and features of the invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be learned from practice of the invention.

[0040] The following will refer to the appendices in the embodiments of the present invention. Figure 1-16 The technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0041] Example 1: To address the technical problem that traditional roof roll material installation equipment can only achieve single-plane installation and cannot flexibly adapt to the transition between horizontal planes and sidewalls, or between horizontal planes and vertical installations, this example provides a roof roll material installation device, including a frame 1. The frame 1 has a U-shaped structure, with rollers on both rear sides and a double wheel set in the middle of the front side. The two rollers and the double wheel set serve as the load-bearing and moving elements of the frame 1. A handle is provided on the rear side of the frame 1 for manual gripping to drive the frame 1 to move.

[0042] See attached document Figure 9 As shown, the frame 1 has two sets of guide rails 4 spaced apart at the front and rear. Both ends of the two sets of guide rails 4 are connected to mounting seats, which are fastened to the frame 1 with bolts. A movable frame 2 is mounted on both sets of guide rails 4. The lower end of the movable frame 2 has two arched legs spaced apart on the left and right. Both ends of the two legs are provided with rail sleeves 3, which are fitted onto the guide rails 4, thereby realizing the sliding installation of the movable frame 2 on the guide rails 4.

[0043] To achieve locking of the movable frame 2 after it moves on the frame 1 (i.e., the change between the horizontal film laying position and the bending film laying position), refer to the attached... Figure 8As shown, a screw hole is provided on the track sleeve 3, and a positioning bolt 10 is screwed into the screw hole (the positioning bolt 10 is hidden in the screw hole in the attached figure). The guide rail 4 has positioning holes 11 at the beginning and end of the travel of the moving frame 2 for the positioning bolt 10 to be inserted. In the horizontal film laying position, the positioning bolt 10 is connected in series with the screw hole and the positioning hole 11 on the left side; in the bending film laying position, the positioning bolt 10 is connected in series with the screw hole and the positioning hole 11 on the right side. With the cooperation of the track sleeve 3 and the guide rail 4, the moving frame 2 can only move left and right, and with the cooperation of the positioning bolt 10, the moving frame 2 can be locked after it has been moved.

[0044] See attached document Figure 6 As shown, the upper end of the movable frame 2 is provided with an arc-shaped support 5, and an arc-shaped arch 6 is placed on the surface of the support 5, with the bottom surface of the arch 6 in contact with the surface of the support 5; a material box 7 is fixed to the upper end of the arch 6, and the material box 7 is used to hold the roll material. Through the cooperation between the arch 6 and the support 5, the material box 7 can deflect along the arc-shaped trajectory.

[0045] To enable the arch frame 6 to move on the support 5 and to prevent the arch frame 6 from detaching from the support 5 without active disassembly, refer to the attached... Figure 14 , 15 As shown, two sets of sliding grooves are spaced apart on the surface of the support 5, and the grooves penetrate the support 5. Two sets of sliders 8 are integrally welded to the bottom end of the arch frame 6. The two sliders 8 are inserted into the sliding grooves, thereby limiting the arch frame 6 and restricting its deflection trajectory. The sliding grooves only penetrate the right side of the support 5, so that the arch frame 6 can only be driven to deflect to the right. After passing through the sliding grooves, the two sets of sliders 8 are detachably connected to a connecting plate 9. The connecting plate 9 is connected to the sliders 8 by bolts, forming a locking structure on the side of the support 5 away from the arch frame 6, which can prevent the arch frame 6 from detaching from the support 5. The contact surface between the arch frame 6 and the support 5 is provided with friction texture to increase frictional resistance and prevent easy autonomous deflection under non-active driving conditions.

[0046] See attached document Figure 7 As shown, to achieve coordinated movement between the arch frame 6 and the moving frame 2, a pull rope 24 is fixedly connected to the bottom left side of the arch frame 6. The pull rope 24 is a steel cable, and the support 5 has a slot for the pull rope 24 to pass through, which runs through the left side of the support 5. A reversing roller 25 is provided on the left support leg of the moving frame 2. After the pull rope 24 passes through the slot, it goes around the reversing roller 25 and then connects to the left side of the frame 1. When the moving frame 2 moves to the right, the pull rope 24 pulls the left side of the arch frame 6, causing the arch frame 6 to deflect on the support 5: the left side sinks and the right side tilts upward. After the moving frame 2 is locked by the positioning bolt 10, the arch frame 6 is also pulled on the support 5 by the pull rope 24, and the slider 8 abuts against the end of the groove, thus maintaining stability.

[0047] To guide the unwinding of the roll material stored in the material box 7 and assist in the transition from a flat state to a bent state, refer to the attached... Figure 6, 9 As shown, a truss plate 17 is fixedly installed on the left side of the movable frame 2, and a fixed roller group 12 and a fixed roller group 2 13 are provided on the horizontal plate; a movable plate 16 is provided on the right side of the arch frame 6 under the material box 7, and a movable roller group 14 is provided on the movable plate 16; a movable roller group 2 15 is provided on the right side of the movable frame 2. The fixed roller group 12 corresponds to the movable roller group 14, and the fixed roller group 2 13 corresponds to the movable roller group 2 15. Each of the fixed roller group 12, fixed roller group 2 13, movable roller group 14, and movable roller group 2 15 contains two sets of rotating rollers, and there is a gap between the two sets of rotating rollers, which is the gap through which the roll material passes. The pulling end of the roll material passes through the fixed roller group 12 and the movable roller group 14 simultaneously, and then passes through the fixed roller group 2 13 and the movable roller group 2 15 simultaneously, thereby guiding the unwinding of the roll material. Since the movable roller group 14 is set on the material box 7, the movable roller group 14 will tilt to the side synchronously with the material box 7; while the movable roller group 2 15 will rotate 90° as the material box 7 tilts to the side.

[0048] To achieve the 90° rotation of the movable roller assembly 215 as it tilts to the side of the material box 7, refer to the attached... Figure 9 As shown, the lower ends of the two sets of rail sleeves 3 on the front side of the movable frame 2 are connected to a mounting plate. A rotating shaft is rotatably mounted on the mounting plate. A gear 18 is fixed at one end of the rotating shaft. The gear 18 meshes with a rack 19 fixedly mounted on the frame 1. An L-shaped side frame is fixedly mounted at the other end of the rotating shaft. The two rotating rollers of the movable roller group 2 15 are set on the side frame.

[0049] Based on the above technical solution; When using the equipment, first place the frame 1 stably on the roof construction area, ensuring that the bottom of the frame 1 is firmly attached to the roof surface without any shaking. Adjust the placement of the frame 1 according to the size and shape of the construction area to cover the edge of the area to be paved. Next, check the sliding fit between the movable frame 2 and the frame 1, ensuring that the movable frame 2 slides smoothly left and right along the frame 1 without any jamming. Then, place the cylindrical roll of material into the material box 7, ensuring that the roll is placed stably within the material box 7 without any movement.

[0050] Then, pull the free end of the roll material through the output port of the material box 7, first entering the gap between the fixed roller group 12 and the movable roller group 14. The two sets of rotating rollers of the fixed roller group 12 and the movable roller group 14 are symmetrically distributed to ensure that the roll material can be clamped by the two sets of rotating rollers without being excessively squeezed. After the roll material passes through the fixed roller group 12 and the movable roller group 14, it continues to be pulled into the gap between the fixed roller group 23 and the movable roller group 25, where the roll material is also clamped by the two sets of rotating rollers. At this time, the tension of the roll material needs to be adjusted to ensure that the surface of the roll material is flat and free of wrinkles or misalignment. Finally, the free end of the roll material is placed at the starting position of the laying.

[0051] Next, the roof surface is paved horizontally, keeping the material box 7 in an initial, non-biased state. At this time, the movable roller group 14 and the fixed roller group 12 are parallel and aligned, and the movable roller group 25 and the fixed roller group 23 are parallel and aligned. During the movement of the frame 1, the roll material is pulled out from the material box 7 at a uniform speed under the coordinated clamping and guiding action of the fixed roller group 12, movable roller group 14, fixed roller group 23, and movable roller group 25. Since all four roller groups adopt a symmetrical structure of two sets of rotating rollers, they form a double-sided clamping of the roll material, which can effectively limit the deviation of the roll material in the left and right directions. At the same time, the rotation of the rotating rollers reduces the friction between the roll material and the roller group, ensuring that the roll material output process is smooth and stable. The construction personnel can control the speed of the frame 1 according to the paving requirements to ensure that the roll material is laid flat, without bubbles or wrinkles, until the horizontal surface paving of this area is completed.

[0052] When vertical paving is required at the junction of the side wall and the horizontal plane, unscrew the positioning bolt 10, push the moving frame 2 to the right side of the frame 1 to the end of the stroke, and then screw the positioning bolt 10 in to fix the moving frame 2. During the transfer of the moving frame 2, one end of the pull rope 24 connected to the bottom of the arch frame 6 moves synchronously with the arch frame 6, pulling the pull rope 24 to slide along the reversing roller 25, and the tension gradually increases, thereby pulling the arch frame 6, causing the arch frame 6 to deflect laterally along the arc surface of the support 5, and then causing the material box 7 to deflect laterally along the arc support 5 on the moving frame 2 towards the side wall, until the slider 8 moves to the right end of the chute. After the moving frame 2 is locked, the taut state of the pull rope 24 is determined. Under the constraints of the pull rope 24, the chute and the slider 8, the arch frame 6 remains in a deflected state. During the lateral deviation of material box 7, the movable roller group 14 located on the right side of material box 7 deviates synchronously with material box 7, always maintaining contact with the roll material output from material box 7 to ensure the guiding stability of the roll material in the lateral deviation direction, allowing the roll material to begin initial lateral deviation during unwinding. Simultaneously, during the transfer of the moving frame 2, due to the meshing of gear 18 and rack 19, the rotating shaft rotates counterclockwise, thereby driving the movable roller group 15 to rotate 90° counterclockwise, changing from a horizontal state parallel to the fixed roller group 13 to a vertical state perpendicular to the fixed roller group 13. At this time, the fixed roller group 13 and the movable roller group 15 form a vertical clamping and guiding structure. After being guided by the right side of the fixed roller group 12 and the movable roller group 14, the roll material enters the vertical state between the fixed roller group 13 and the movable roller group 15, and is clamped and guided to the junction of the side wall and the horizontal plane, achieving vertical laying.

[0053] After the vertical paving conversion is completed, the pusher frame 1 moves at a constant speed. Under the coordinated action of the four sets of rollers, the roll material is smoothly output and adhered to the junction of the side wall and the horizontal plane. Because the movable roller set 14 and the material box 7 are synchronously tilted to the side, the movable roller set 2 15 rotates vertically and precisely cooperates with the fixed roller set 2 13, ensuring that the roll material remains flat and without deviation throughout the vertical paving process. Construction personnel can observe the paving status of the roll material and adjust the sliding speed and direction of the moving frame 2 in real time to ensure the quality of the vertical paving until the paving is completed.

[0054] After completing the installation of one area, the unrolled material is cut appropriately, the moving frame 2 is reset to its initial position, the material box 7 is adjusted, the free end of the material is re-threaded and fixed, and the above installation process is repeated until the installation of the material in the entire roof area is completed.

[0055] This embodiment achieves rapid conversion between horizontal and vertical paving without disassembling the equipment or replacing parts through the lateral adjustment of the material box 7 and the linkage adaptation of movable roller group one 14 and movable roller group two 15. The operation process is simple and easy to understand, and construction personnel can operate it proficiently after simple training. At the same time, the linkage structure of the equipment reduces manual adjustment steps and lowers the labor intensity of construction personnel.

[0056] All four roller sets employ a symmetrical clamping structure with two sets of rotating rollers, providing double-sided guidance and limiting for the roll material, effectively preventing lateral deviation and wrinkling during the pulling process. Simultaneously, movable roller set 14 tilts laterally in sync with the material box 7, guiding the roll material through bending in advance. Then, movable roller set 2 15 rotates 90° adaptively, always maintaining contact with the roll material's output direction, ensuring stable output of the roll material under different laying directions. This transitional change in the roll material reduces some torsional stress and minimizes unevenness in the roll material laying process.

[0057] In this embodiment, during the conversion between planar and vertical roll material laying, the purpose of adjusting the position of the movable frame 2 is to move the movable roller group 14 and movable roller group 25 out of the frame 1, so as to extend the bent part of the roll material out of the frame 1 as much as possible, and avoid the frame 1 causing significant interference to the roll material laying.

[0058] In this embodiment, the surfaces of the two rotating rollers of the fixed roller group 12, the fixed roller group 23, the movable roller group 14, and the movable roller group 25 are all provided with rubber pads to form soft clamping, ensuring that the roll material can be clamped by the two sets of rotating rollers without being excessively squeezed, and also preventing the roll material from being over-unwound when being pulled.

[0059] In Example 2, to address the technical problem that the right-angled structure at the end of the movable roller group 14 in contact with the roll material easily leads to stress concentration, causing wear and damage to the roll material edges, thus affecting the waterproof performance and service life of the roll material, the end of the movable roller group 14 facing the fixed roller group 12 is hemispherical. The surface of the hemispherical end is polished, making it smooth and burr-free. Compared with the right-angled end, the hemispherical end has a larger contact area with the roll material and disperses stress. For thicker roll materials, the curved contact of the hemispherical end can effectively disperse pressure and prevent the roll material from being excessively squeezed; for thinner roll materials, the gentle contact of the hemispherical end can prevent the roll material from being scratched or torn, improving the adaptability of the equipment to roll materials of different specifications.

[0060] Example 3: To address the poor synergistic clamping effect between the movable roller group 2 15 and the fixed roller group 2 13 after rotation, especially the inability to provide effective top pressure limiting at the bending points of the roll material, refer to the attached... Figure 13 As shown, a hammer 20 is embedded in the right end of the fixed roller group 2 13. The end of the hammer 20 is chamfered to prevent the edge from cutting the roll material. A telescopic shaft 21 is embedded in the left end of the movable roller group 2 15. A straight groove frame 22 is provided on the end of the telescopic shaft 21 facing the hammer 20. A slot for inserting the straight groove frame 22 is provided on the end of the hammer 20 facing the straight groove frame 22. An insertion rod 23 is provided in the slot for inserting into the straight groove frame 22. The insertion rod 23 is a pre-drilled bolt. The bolt and the corresponding nut are both concealed, that is, the end of the mounting hole is provided with a countersunk groove.

[0061] Based on the above technical solution: During horizontal paving, the movable roller group 2 15 is in a horizontal position, parallel and corresponding to the fixed roller group 2 13. At this time, both the hammer 20 and the telescopic shaft 21 are in a retracted state, the straight groove frame 22 is aligned with the insertion port of the hammer 20, the straight groove frame 22 is inserted into the insertion port, and the insertion rod 23 inside the insertion port is inserted into the groove of the straight groove frame 22, achieving precise docking between the fixed roller group 2 13 and the movable roller group 2 15. After docking, the two sets of rotating rollers of the fixed roller group 2 13 and the movable roller group 2 15 form a tight clamping structure.

[0062] When the material box 7 tilts to the side, the movable roller group 2 15 rotates with the side frame, driving the telescopic shaft 21 and the straight groove frame 22 to rotate synchronously. Since the straight groove frame 22 and the hammer 20 are connected by the insertion rod 23, in the initial stage of rotation, the insertion rod 23 moves within the straight groove of the straight groove frame 22 to adjust the movement gap. At the same time, the hammer 20 is pulled out of the fixed roller group 2 13, that is, the horizontal length of the fixed roller group 2 13 extends, tending to abut against the bend of the ground side wall, that is, against the area where the roll material needs to be bent at 90°. It works in conjunction with the fixed roller group 2 13 and the movable roller group 2 15 to form a tight clamping structure in the vertical direction, providing a stable limiting top pressure for the roll material bending, assisting the roll material to bend at 90° and bend shaping, and reducing the problem of loosening and displacement during vertical laying.

[0063] In this embodiment, the non-rigid connection between the insert rod 23 and the straight groove frame 22 provides a pulling force to the head hammer 20 while the movable roller group 25 deflects, and also creates sufficient clearance between the head hammer 20 and the straight groove frame 22 during the rotation of the movable roller group 25, preventing jamming. Combined with the chamfered design at the end of the head hammer 20, this prevents the movable roller group 25 from experiencing a hard collision or interference with the head hammer 20 during rotation, ensuring the smoothness and stability of the movable roller group 25's rotation. The chamfered design at the end of the head hammer 20 prevents hard friction between the edge of the roll material and the end of the roller group, and the precise alignment of the straight groove frame 22 and the insert ensures uniform clamping force on the roll material, reducing wear and damage to the roll material edges and protecting the integrity of the roll material.

[0064] During construction, workers should regularly check the wear of the hammer 20, straight slot frame 22, insertion rod 23, and telescopic shaft 21. If severe wear or deformation is observed, they should be replaced promptly to ensure docking accuracy. Simultaneously, dust and debris on the insertion port and straight slot frame 22 should be cleaned regularly to ensure a smooth docking process.

[0065] Example 4: To achieve stable placement of the roll material within the material box 7, refer to the attached... Figure 11 , 12 As shown, the material box 7 includes a box body 71 and a box cover 72. The front side of the box body 71 has a discharge port for unwinding the rolled material. The rear end of the box body 71 has an arc-shaped back, and the upper end of the box body 71 has a notch for the box cover 72 to fit into. The contact surface between the back side of the box body 71 and the box cover 72 is a wedge-shaped surface 73 with an inclination angle of 15-30°, ensuring a tight fit between the box cover 72 and the box body 71 without gaps, and avoiding an excessively large angle that would prevent the box cover 72 from unfolding along the wedge-shaped surface 73. Both ends of the box body 71 are rotatably mounted with swing rods 74. The ends of the swing rods 74 are open, and connecting blocks 75 are slidably installed within the openings. A tension spring is provided between the connecting blocks 75 and the bottom wall of the opening. Multiple connecting claws 76 are evenly distributed on the connecting blocks 75. The shape of the connecting claws 76 is adapted to the fixed connection of the end of the box cover 72 to ensure a secure fastening; this can be achieved by bolts or welding.

[0066] In this embodiment, the lid 72 and the front of the box body 71 are provided with a latch, such as a pin connection or a hook connection, to prevent the material box 7 from being opened during use and causing the roll material to fall out.

[0067] Based on the above technical solution: In use, open the latch between the lid 72 and the body 71, and lift the lid 72. During the opening process, the lid 72 deflects along the rotation center of the swing rod 74. Through the smooth connection of the wedge-shaped surface 73, the lid 72 is pushed up along the wedge-shaped surface 73, and the connecting block 75 slides within the opening of the swing rod 74, stretching the tension spring. Then, the lid 72 is moved along the curved back of the body 71, so that the lid 72 is in a vertically open state, at which point the roll material can be placed in. After the roll material is placed in, pull the unwinding end of the roll material out from the discharge port. Then, the operator releases the swing rod 74, which rotates in the opposite direction under its own weight or with manual assistance, aligning the connecting claw 76 on the connecting block 75 with the slot at the end of the lid 72. The tension spring generates tension in the opening, pulling the connecting block 75 towards the end of the rocker arm 74. The connecting claw 76 tightly engages in the slot at the end of the lid 72, achieving elastic locking of the lid 72; then it can be locked by the latch.

[0068] The entire operation is simple and quick, requiring no complicated tools, which reduces the labor intensity of changing the roll material and improves construction efficiency.

[0069] The elastic locking structure composed of the swing rod 74, connecting block 75, tension spring and connecting claw 76, through the continuous tension of the tension spring, makes the connecting claw 76 tightly fasten to the end of the box cover 72, ensuring that the box cover 72 and the box body 71 are tightly connected. With the lock, the material box 7 does not loosen during the installation process.

[0070] In this embodiment, this embodiment is designed to address the technical problem that when the roll material is output from the material box 7, the direct contact between the roll material and the outlet of the box body 71 generates significant sliding friction, resulting in uneven roll material output and easy wear on the roll material surface, thus affecting the waterproof performance and installation efficiency of the roll material. (Refer to the attached...) Figure 11 As shown, rotating rollers 77 are rotatably mounted on the front interfaces of both the box body 71 and the box cover 72, and the roll material pulling end passes through the two sets of rotating rollers 77. During the roll material pulling process, the rotating rollers 77 rotate synchronously under the action of the roll material's friction force, converting the sliding friction between the roll material and the box body 71 and the box cover 72 into rolling friction between the rotating rollers 77 and the roll material, significantly reducing frictional resistance.

[0071] The rotating roller 77 is made of wear-resistant rubber material with a smooth surface, good elasticity and wear resistance, which can reduce friction with the surface of the roll material and avoid scratching the roll material.

[0072] The overall operation process is as follows, detailing the operation procedures, component linkages, and construction details of each stage: (1) Select the appropriate specifications of the roll material according to the construction requirements, roll the roll material into a cylindrical shape, open the cover 72 of the material box 7, and place the roll material smoothly into the box body 71, ensuring that the central axis of the roll material is parallel to the arc back of the box body 71. Pull the free end of the roll material so that it passes through the two sets of rotating rollers 77 at the front interface of the material box 7, and then passes through the gap between the fixed roller group 12 and the movable roller group 14 in sequence, and the gap between the fixed roller group 2 13 and the movable roller group 2 15. Adjust the tension of the roll material to ensure that the surface of the roll material is flat at the beginning, without wrinkles or deviation. Finally, temporarily fix the free end of the roll material to the starting position of the paving by means of pressure strips or nails.

[0073] (2) For the installation of the roll material on the horizontal roof, keep the material box 7 in the initial state without deflection, at which time the pull rope 24 is in a naturally taut state. The movable roller group 14 is parallel to the fixed roller group 12, and the movable roller group 25 is parallel to the fixed roller group 23. The straight groove frame 22 is inserted into the insertion port of the head hammer 20, and the insertion rod 23 is inserted into the groove of the straight groove frame 22 to achieve precise docking of the two roller groups. During the movement of the frame 1, the roll material is pulled out from the material box 7 at a uniform speed under the coordinated clamping and guiding action of the fixed roller group 12, movable roller group 14, fixed roller group 23, and movable roller group 25.

[0074] (3) For the roll material installation at the right angle where the horizontal ground meets the side wall, unscrew the positioning bolt 10, push the moving frame 2 to the right side of the frame 1 to the end of the stroke, and then screw the positioning bolt 10 in to fix the moving frame 2. During the transfer of the moving frame 2, one end of the pull rope 24 connected to the bottom of the arch frame 6 moves synchronously with the arch frame 6. Since the other end of the pull rope 24 is fixed, the rope that pulls the pull rope 24 will slide along the reversing roller 25, and the tension will gradually increase, thereby pulling the arch frame 6, so that the arch frame 6 will deflect laterally along the arc surface of the support 5, and even the side of the material box 7 facing the side wall will deflect laterally towards the side wall along the arc support 5 on the moving frame 2 and tilt up. Until the slider 8 moves to the right end of the chute, after the moving frame 2 is locked, the taut state of the pull rope 24 is determined. Under the constraint of the pull rope 24, the chute and the slider 8, the arch frame 6 remains in a deflected state.

[0075] During the side-biasing process of material box 7, the movable roller group 14 located on the right side of material box 7 tilts synchronously with material box 7, causing the roll material to initially tilt. Simultaneously, during the transfer of the moving frame 2, due to the meshing of gear 18 and rack 19, the rotating shaft rotates counterclockwise, thereby driving the movable roller group 15 to rotate 90° counterclockwise, changing it from a horizontal state parallel to the fixed roller group 13 to a vertical state perpendicular to the fixed roller group 13. At this time, the fixed roller group 13 and the movable roller group 15 form a vertical clamping and guiding structure. After being guided by the right side of the fixed roller group 12 and the movable roller group 14, the roll material enters the vertical state between the fixed roller group 13 and the movable roller group 15, and is clamped and guided to the junction of the side wall and the horizontal plane.

[0076] During the rotation of the second movable roller assembly 15, it drives the telescopic shaft 21 and the straight groove frame 22 to rotate synchronously. Since the straight groove frame 22 is connected to the insertion port of the hammer 20 via the insertion rod 23, during rotation, the straight groove frame 22 exerts an outward pulling force on the hammer 20 through the insertion rod 23, thereby pulling the hammer 20 out of the fixed roller assembly 13. This extends the horizontal length of the fixed roller assembly 13, tending to abut against the bend at the joint with the side wall on the ground, i.e., against the area where the roll material needs to be bent at 90°. This forms a tightly clamping structure in the vertical direction with the fixed roller assembly 13 and the second movable roller assembly 15, providing a stable limiting top pressure for the roll material bending, assisting in the 90° bending and shaping of the roll material. Construction workers must constantly monitor the installation status of the roofing membrane to ensure it is tightly fitted to the sidewalls and horizontal surfaces, without gaps, wrinkles, or misalignment. If gaps occur, the sliding speed of the moving frame 2 can be adjusted appropriately to ensure the membrane is fully fitted; if wrinkles appear, movement should be paused, the membrane tension adjusted, and then continued.

[0077] This solution prioritizes manual operation to minimize the use of electronic components. This is because using electronic components during roof roll roofing requires either powering the equipment with extension cords, installing batteries, or using diesel / gasoline power. These structures increase the load on the equipment, reduce operational flexibility, and increase energy consumption. Furthermore, the use of extension cords can lead to a chaotic construction site and pose safety hazards.

[0078] This design allows for the interchange of gears 18 and racks 19 with different transmission ratios, enabling the setting of different rotation angles for the movable roller assembly 15, thus adapting to a wider range of applications.
