Description

TECHNICAL FIELD

[0002] Slope roof construction is a high-altitude operation, and due to its special structure and environmental factors, there is a high safety risk. Especially on a roof with a large slope, construction personnel are prone to falling or falling. In order to solve this problem, some innovative safety protection measures have been gradually introduced in recent years. These measures can automatically adjust according to the roof slope and environmental changes to ensure that construction personnel can be adequately protected under different conditions. In addition, by strengthening risk assessment and planning before construction, reasonable arrangement of protection facilities and operation routes can further reduce the possibility of accidents. Modern monitoring and feedback systems can monitor changes in the construction environment in real time and take preventive measures in a timely manner, making safety management more accurate. Overall, these technologies and management methods improve the safety of slope roof construction and effectively reduce the risk of high-altitude operation, ensuring the safety of construction personnel.

[0003] However, in actual use, the existing scheme mostly uses scaffolding and protective nets to protect construction personnel. Although this method can provide some safety protection for construction personnel, it also has some limitations. First, in slope roof construction, especially in rainy, snowy or more dew days, roof materials such as metal and smooth tiles are prone to become slippery. Wet and slippery slope roofs can cause construction personnel to lose balance, increasing the risk of slipping, tools falling, and other safety hazards. Roof dirt or water accumulation can also increase the risk of slipping. Unstable support points and wind in extreme weather can further increase the risk. In addition, protective nets have limited effect on preventing construction personnel from falling from scaffolding, especially in strong winds, protective facilities may not be able to effectively resist the effects of strong winds.

[0017] S1: first, the first hydraulic rod drives the transmission gear rod to ascend and descend according to actual needs, and simultaneously limits the two chains through the transmission gear rod; when the transmission gear rod ascends and descends, the chain connected with one end of the lifting rod drives the lifting rod to ascend and descend, so that the height of the equipment is adjusted; then, the slot rod, the second hinge, the storage box, the lifting rod, the first hinge and the slot rod are connected and installed through bolts; then, the equipment is erected, the supporting legs are unfolded to support the outer tube, and the protective net and the operation platform are installed;

[0018] S2: the motor drives the lead screw and the universal transmission rod to rotate through the first pulley set; the rotation of the lead screw can drive the threaded sliding table to move outward, so that the position of the platform angle adjusting assembly and the operation platform is adjusted; in this process, the first pulley set drives the universal transmission rod to rotate, the first bevel gear and the second bevel gear are driven to rotate through the universal transmission rod, and the connecting rod is driven to rotate through the second bevel gear; in this process, the winding wheel is driven to rotate through the cooperation of the connecting rod and the second pulley set, so that the safety rope wound by the winding wheel is discharged through the wire outlet hole.

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.

[0024] 2.

[0053] A method for using a protective device for pitched roof construction includes the following steps:

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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, based on the protective device for pitched roof construction as described in claim 8, characterized in that, The method 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 telescopic end of the second hydraulic rod (42), and the rotation angle of the rotating plate (41) is adjusted by extending the telescopic 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.
