Description

Technical Field

[0001] This invention relates to the field of building construction protection technology, and in particular to a protective device for sloping roof construction and its usage method. Background Technology

[0002] Sloping roof construction, as a type of high-altitude work, carries significant safety risks due to its unique structure and environmental factors, especially on steep roofs where workers are prone to slipping or falling. To address this issue, innovative safety measures have been gradually introduced in recent years. These measures automatically adjust to changes in roof slope and environmental conditions, ensuring adequate protection for workers under varying circumstances. Furthermore, enhanced pre-construction risk assessment and planning, along with the rational arrangement of protective facilities and work routes, further reduce the likelihood of accidents. Modern monitoring and feedback systems enable real-time monitoring of changes in the construction environment and timely preventative measures, resulting in more precise safety management. Overall, these technologies and management methods improve the safety of sloping roof construction, effectively reduce the risks of working at height, and ensure the safety of construction workers.

[0003] However, in practice, existing solutions mostly employ scaffolding combined with safety nets to protect construction workers. While this method provides some safety, it also has limitations. First, during pitched roof construction, especially in rainy, snowy, or dewy weather, roof materials such as metal and smooth tiles can become slippery. A wet, slippery roof can cause workers to lose their balance, increasing the risk of slips, falls, and tools slipping. Dirty or wet roofs can also exacerbate the risk of slipping, and unstable support points and strong winds in extreme weather conditions further increase the danger. Furthermore, safety nets are only partially effective at preventing workers from falling from scaffolding, especially in strong winds where they may not be able to effectively withstand the force of the wind.

[0004] Therefore, the present invention provides a protective device for pitched roof construction and a method for using it. Summary of the Invention

[0009] As a preferred technical solution of this application, the platform angle adjustment component includes a support platform, the lower bottom surface of the support platform is fixedly connected to the upper surface of the threaded slide, a rotating plate is rotatably connected to the side of the support platform away from the threaded slide, the rotating plate has sliding grooves on both sides inside, a second hydraulic rod is rotatably connected to the inner side of the support platform, a support rod is rotatably connected to the telescopic end of the second hydraulic rod, one end of the support rod is rotatably connected to the support platform, the other end of the support rod is slidably assembled in the sliding groove, and the upper surface of the rotating plate is fixedly connected to the lower bottom surface of the operating platform.

[0011] As a preferred technical solution of this application, the automatic safety rope cable laying assembly includes a support frame, which is fixedly connected to the inner wall of the storage box.

[0012] As a preferred technical solution of this application, the outer wall of the storage box is provided with a plurality of evenly distributed cable outlet holes.

[0013] As a preferred technical solution of this application, a plurality of evenly distributed pins are provided on both sides of the outer wall of the outer tube, a protective net is fixedly connected to the outside of the pins, and a plurality of evenly distributed support legs are provided on the outside of the bottom end of the outer tube.

[0014] As a preferred technical solution of this application, a slot is provided in the middle section of the bottom surface of the storage box, and multiple evenly distributed spotlights are fixedly connected to the top surface of the storage box.

[0015] As a preferred technical solution of this application, a method for using a protective device for pitched roof construction includes the following steps: S1: First, the first hydraulic rod drives the transmission rack to lift and lower according to actual needs. At the same time, the transmission rack limits the chains on both sides. When the transmission rack lifts and lowers, the end of the chain connected to the lifting rod drives the lifting rod to lift and lower, thereby adjusting the height of the equipment. Then, the slotted rod, second hinge, storage box, lifting rod, first hinge, and slotted rod are connected and installed with bolts. After that, the equipment is erected, the support legs are extended to support the outer tube, and the protective net and operating platform are installed. S2: The motor drives the lead screw and universal joint rod to rotate simultaneously via the first pulley set. The rotation of the lead screw drives the threaded slide to move outward, adjusting the position of the platform angle adjustment component and the operating platform. During this process, the universal joint rod is driven to rotate via the first pulley set, which in turn drives the first bevel gear and the second bevel gear to rotate. The second bevel gear drives the connecting rod to rotate. In this process, the connecting rod and the second pulley set work together to drive the winding wheel to rotate, thereby releasing the safety rope wound by the winding wheel through the cable outlet. S3: The support rod is erected by extending the extension end of the second hydraulic rod, and the rotation angle of the rotating plate is adjusted by extending the extension end of the second hydraulic rod to ensure that the rotating plate and the operating platform are in close contact. S4: Construction workers climb onto the operating platform and connect the safety rope to themselves. During construction, the motor and the first pulley set work together to drive the universal drive rod and the lead screw to rotate. When the lead screw drives the threaded slide to move upward, the universal drive rod drives the winding wheel to rotate through the first bevel gear, the second bevel gear, the connecting rod, and the second pulley set, thereby achieving the function of winding the safety rope. Conversely, when the threaded slide moves downward, the winding wheel will reverse to release the safety rope. S5: During the winding and unwinding of the safety rope, the connecting rod can drive the twisted rod to rotate synchronously. The rotation of the twisted rod drives the moving plate to move back and forth within the support frame. In turn, the moving plate drives the lead-out ring to move back and forth. The safety rope is connected to the take-up reel through the lead-out ring. This allows the safety rope to be laid out during the winding and unwinding process of the take-up reel, preventing the safety rope from getting tangled on the outside of the take-up reel during subsequent use, thus avoiding a threat to the personal safety of construction workers.

[0016] Compared with the prior art, the present invention provides a protective device for pitched roof construction and its usage method, which has the following beneficial effects: 1. The protective device and its usage method for sloping roof construction described in this invention use a platform moving component to drive the operating platform to move up and down, thereby enabling workers to move on the sloping roof and providing them with a stable working platform. This prevents workers from slipping or losing their balance during sloping roof construction. Through the synchronous movement of the operating platform, workers always stand on the operating platform, reducing the danger of walking directly on the wet and slippery roof. At the same time, workers no longer need to frequently move back and forth or adjust their positions on the roof, reducing fatigue caused by frequent equipment handling or changing work positions, and also reducing the probability of accidents caused by unstable operation. 2. The protective device and its usage method for sloping roof construction described in this invention, by using the platform moving component to drive the operating platform to move up and down, the transmission component drives the automatic safety rope laying component and the winding wheel to run, thereby automatically winding and unwinding the safety rope. In traditional construction, the safety rope may become slack or tangled due to factors such as worker movement, changing position, or wind, which increases safety hazards. However, by automatically winding and unwinding the safety rope, this situation can be avoided, ensuring that the safety rope is always in an appropriate tension state and preventing workers from being disturbed by rope problems. 3. The protective device and its usage method for pitched roof construction described in this invention, through the cooperation of the telescopic rod assembly and the outer pipe, can be used for construction on pitched roofs of different heights. At the same time, through the cooperation of the platform moving assembly and the platform angle adjusting assembly, the equipment can be adapted to pitched roof construction environments of different angles, greatly improving the flexibility of the equipment and thus increasing its market competitiveness. 4. The protective device and its usage method for pitched roof construction described in this invention utilizes a modular design. This modular design provides flexibility and customizability, allowing adjustments to be made according to different pitched roof conditions and construction needs. It also simplifies the installation and disassembly process, improves construction efficiency, facilitates rapid deployment and recovery of the equipment, and makes maintenance and replacement easier. Damaged parts can be replaced individually, reducing maintenance costs. Furthermore, the modular design allows for optimized configuration based on site requirements, improving safety. Standardized production reduces manufacturing and procurement costs, thus enhancing the overall adaptability, convenience, economy, and safety of the equipment. Attached Figure Description

A transmission rack 21 is provided at the lifting end of the first hydraulic rod 2. Chains 22 are meshed on both sides of the transmission rack 21. The first hydraulic rod 2 fixes the transmission rack 21, while gears are rotatably connected to both sides of the transmission rack 21. Thus, during the lifting and lowering process driven by the first hydraulic rod 2, the chain 22 is limited. One end of the chain 22 is fixedly connected to the lower inner wall of the base 14, and the other end of the chain 22 is fixedly connected to both sides of the bottom wall of the lifting rod 23.

The lead screw 33 is threadedly connected to the threaded slide table 35, and the lead screw 33 limits the threaded slide table 35. The rotation of the lead screw 33 drives the threaded slide table 35 to move along the grooved rod 3. A cover plate 34 is fixedly connected above the grooved rod 3. The cover plate 34 is slidably connected to the threaded slide table 35. The grooved rod 3 supports and fixes the cover plate 34, and at the same time, the cover plate 34 protects the grooved rod 3, preventing materials generated during construction from falling into the grooved rod 3 and affecting the operation of the equipment.

[0023] The platform angle adjustment assembly includes a support platform 4, which is fixedly connected to a threaded slide 35. The threaded slide 35 supports and fixes the support platform 4, and the threaded slide 35 and the support platform 4 are connected by bolts.

One end of the support rod 43 is rotatably connected to the support platform 4. The support platform 4 limits the bottom end of the support rod 43. The other end of the support rod 43 is slidably assembled in the slide groove 44. The telescopic end of the second hydraulic rod 42 drives the support rod 43 to rotate around the connection point between the support rod 43 and the support platform 4, thereby supporting the rotating plate 41 and adjusting the angle of the rotating plate 41.

[0025] The automatic safety rope cable laying assembly includes a support frame 6, which is fixedly connected to the inner wall of a storage box 7. The storage box 7 fixes the support frame 6. A twisted rod 61 is rotatably connected to the inner side of the support frame 6, limiting the twisted rod 61. The twisted rod 61 is fixedly sleeved on the outer side of a connecting rod 53, which fixes the twisted rod 61 and drives the twisted rod 61 to rotate. A movable plate 62 is threadedly connected to the outer side of the twisted rod 61, which drives the movable plate 62 to reciprocate laterally on the outer side of the twisted rod 61. A cable exit ring 63 is fixedly connected to the outer side of the movable plate 62, which fixes the cable exit ring 63 and drives the cable exit ring 63 to reciprocate synchronously, thereby laying the safety rope for winding and unwinding.

[0026] The outer wall of the storage box 7 has multiple evenly distributed cable outlet holes 56, which provide space for the safety rope to move.

[0027] Multiple evenly distributed pins 12 are provided on both sides of the outer wall of the outer tube 1. A protective net 13 is fixedly connected to the outside of the pins 12.

Multiple evenly distributed spotlights 72 are fixedly connected to the top surface of the storage box 7. The multiple spotlights 72 can provide light source for nighttime operations.

[0029] A method for using a protective device for pitched roof construction includes the following steps: S1: First, the first hydraulic rod 2 drives the transmission rack 21 to rise and fall according to actual needs. At the same time, the transmission rack 21 limits the chains 22 on both sides. When the transmission rack 21 rises and falls, the end of the chain 22 connected to the lifting rod 23 drives the lifting rod 23 to rise and fall at the same time, thereby adjusting the height of the equipment. Then, the groove rod 3, the second hinge 36, the storage box 7, the lifting rod 23, the first hinge 25, and the groove rod 3 are connected and installed with bolts. Then, the equipment is erected, the support legs 11 are unfolded to support the outer tube 1, and the protective net 13 and the operating platform 45 are installed. S2: The motor 31 drives the lead screw 33 and the universal transmission rod 5 to rotate simultaneously via the first pulley group 32. The rotation of the lead screw 33 drives the threaded slide table 35 to move away from the storage box 7, adjusting the position of the platform angle adjustment component and the operating platform 45. During this process, the first pulley group 32 drives the universal transmission rod 5 to rotate, which in turn drives the first bevel gear 51 and the second bevel gear 52 to rotate. The second bevel gear 52 drives the connecting rod 53 to rotate. In this process, the connecting rod 53 and the second pulley group 54 work together to drive the winding wheel 55 to rotate, so that the safety rope wound by the winding wheel 55 can be released through the cable outlet 56. S3: The extension of the telescopic end of the second hydraulic rod 42 drives the support rod 43 to stand up, while the extension of the telescopic end of the second hydraulic rod 42 adjusts the flipping angle of the rotating plate 41 to ensure that the rotating plate 41 and the operating platform 45 are in contact. S4: Construction workers climb onto the operating platform 45 and connect the safety rope to themselves. During the construction process, the motor 31 and the first pulley group 32 work together to drive the universal transmission rod 5 and the lead screw 33 to rotate. When the lead screw 33 drives the threaded slide 35 to move upward, the universal transmission rod 5 drives the winding wheel 55 to rotate through the first bevel gear 51, the second bevel gear 52, the connecting rod 53, and the second pulley group 54, thereby achieving the function of winding the safety rope. Conversely, when the threaded slide 35 moves downward, the winding wheel 55 will reverse to release the safety rope. S5: During the winding and unwinding of the safety rope, the connecting rod 53 can drive the twisted rod 61 to rotate synchronously. The rotation of the twisted rod 61 drives the moving plate 62 to move back and forth within the support frame 6. The moving plate 62 can then drive the lead-out ring 63 to move back and forth. The safety rope is connected to the take-up reel 55 through the lead-out ring 63. This allows the safety rope to be laid out during the winding and unwinding process of the take-up reel 55, preventing the safety rope from getting tangled on the outside of the take-up reel 55 during subsequent use, thus avoiding a threat to the personal safety of construction workers.

10. A method of using a protective device for pitched roof construction, characterized in that, Includes the following steps: S1: First, the first hydraulic rod (2) drives the transmission rack (21) to rise and fall according to actual needs. At the same time, the transmission rack (21) limits the chains (22) on both sides. When the transmission rack (21) rises and falls, the end of the chain (22) connected to the lifting rod (23) drives the lifting rod (23) to rise and fall, thereby adjusting the height of the equipment. Then, the groove rod (3), the second hinge (36), the storage box (7), the lifting rod (23), the first hinge (25), and the groove rod (3) are connected and installed with bolts. Then, the equipment is erected, the support leg (11) is unfolded to support the outer tube (1), and the protective net (13) and the operating platform (45) are installed. S2: The motor (31) drives the lead screw (33) and the universal transmission rod (5) to rotate simultaneously via the first pulley group (32). The rotation of the lead screw (33) can drive the threaded slide (35) to move outward, thereby adjusting the position of the platform angle adjustment component and the operating platform (45). During this process, the first pulley group (32) drives the universal transmission rod (5) to rotate, and the universal transmission rod (5) drives the first bevel gear (51) and the second bevel gear (52) to rotate. The second bevel gear (52) drives the connecting rod (53) to rotate. During this process, the connecting rod (53) and the second pulley group (54) work together to drive the winding wheel (55) to rotate, thereby releasing the safety rope wound by the winding wheel (55) through the cable outlet (56). S3: The support rod (43) is erected by extending the extension end of the second hydraulic rod (42), and the rotation angle of the rotating plate (41) is adjusted by extending the extension end of the second hydraulic rod (42) to ensure that the rotating plate (41) and the operating platform (45) are in contact. S4: Construction workers climb onto the operating platform (45) and connect the safety rope to themselves. During the construction process, the motor (31) and the first pulley group (32) can drive the universal transmission rod (5) and the lead screw (33) to rotate simultaneously. When the lead screw (33) drives the threaded slide (35) to move upward, the universal transmission rod (5) uses the first bevel gear (51), the second bevel gear (52), the connecting rod (53), and the second pulley group (54) to drive the winding wheel (55) to rotate, thereby realizing the function of winding the safety rope. Conversely, when the threaded slide (35) moves downward, the winding wheel (55) will reverse and release the safety rope. S5: During the winding and unwinding of the safety rope, the connecting rod (53) can drive the twisted rod (61) to rotate synchronously. The rotation of the twisted rod (61) drives the moving plate (62) to move back and forth within the support frame (6). Thus, the moving plate (62) can drive the exit ring (63) to move back and forth. The safety rope is connected to the winding wheel (55) through the exit ring (63). This allows the safety rope to be laid out during the winding and unwinding process of the winding wheel (55), preventing the safety rope from getting tangled on the outside of the winding wheel (55) during subsequent use, thus threatening the personal safety of the construction workers.
