[0035] Building construction refers to the process of constructing buildings, encompassing a series of production activities involving the construction of houses, structures, and other ancillary facilities on land in accordance with regulations and standards. This process includes a series of tasks such as building design, construction, installation, acceptance, and use, involving multiple professional fields such as architectural design, civil engineering, decoration and renovation, electrical installation, and water supply and drainage installation.

[0036] However, when the existing fall protection devices are not in use, it is inconvenient for workers to retract the safety net, especially when working on the scaffolding, as the net may block their way and affect the normal construction progress.

[0037] Please refer to Figures 1-5 This embodiment provides a safety fall arrest device 100, which can effectively improve the technical problems mentioned above and solve the technical problem that the protective net is inconvenient to retrieve when the fall arrest device is not in use.

[0038] Please refer to Figures 1-5 The safety fall arrest device 100 includes a fall arrest net 10, a connector 20, a mounting frame 30, and a drive component 40. One end of the connector 20 is connected to the fall arrest net 10, and the other end of the mounting frame 30 is connected to the connector 20. The drive component 40 is disposed on the mounting frame 30 and is connected to the fall arrest net 10. The drive component 40 is used to drive the fall arrest net 10 to rotate relative to the mounting frame 30, so that the fall arrest net 10 opens or retracts.

[0039] Specifically, existing fall arrest devices are generally in the open state during use, and the fall arrest net is required to protect workers working at heights. However, existing fall arrest devices have the problem that the fall arrest net is inconvenient to retract, thus affecting normal work. To solve this technical problem, the safety fall arrest device 100 provided in this embodiment has a driving component 40 on the mounting frame 30 during use. The driving component 40 is connected to the fall arrest net 10. The driving component 40 can drive the fall arrest net 10 to rotate relative to the mounting frame 30, so that the fall arrest net 10 can be flexibly opened and retracted according to the work needs. When it is necessary to protect the safety of construction workers, the driving component 40 drives the fall arrest net 10 to open quickly, and the connecting component 20 can position the fall arrest net 10 in the open position to further enhance the protective effect and avoid secondary injuries. When protection is not required, the driving component 40 drives the fall arrest net 10 to retract quickly, thereby reducing interference with normal work and making it convenient to use.

[0040] In this embodiment, the mounting frame 30 includes a horizontal mounting bar 31 and a vertical mounting bar 32. Both ends of the horizontal mounting bar 31 are connected to the vertical mounting bars 32. The fall arrestor net 10 is rotatably connected to the horizontal mounting bar 31. The driving component 40 and the connecting component 20 are both connected to the vertical mounting bars 32. Specifically, both vertical mounting bars 32 are located on the same side of the horizontal mounting bar 31, and the vertical mounting bars 32 and the horizontal mounting bar 31 are arranged perpendicularly.

[0041] In this embodiment, the two mounting vertical rods 32 and the mounting horizontal rod 31 are integrally formed.

[0042] To facilitate the installation of the safety fall arrestor 100 on a fixed object, at least one mounting rod 32 has an ear seat 34 on its inner side. The ear seat 34 is fixedly installed on the fixed object by a screw, thus ensuring the installation of the safety fall arrestor 100.

[0043] In this embodiment, the ear seat 34 is welded to the inner side of the mounting vertical rod 32. There are two ear seats 34, which are spaced apart in the vertical direction.

[0044] It should be noted that the mounting bracket 30 also includes a shaft 33, which is disposed on the mounting crossbar 31, with both ends of the shaft 33 located outside the mounting crossbar 31. The fall protection net 10 and the shaft 33 are rotatably connected. The shaft 33 is oriented in the same direction as the length of the mounting crossbar 31, is installed inside the mounting crossbar 31, and both ends of the shaft 33 are located outside the mounting crossbar 31. Both ends of the shaft 33 are rotatably connected to the fall protection net 10.

[0045] It should also be noted that the fall arrest net 10 includes a protective frame 11, a fall arrest net body 12, and a collar 13. The fall arrest net body 12 is installed on the protective frame 11, and the protective frame 11 is connected to the end of the connector 20. The collar 13 is disposed on the protective frame 11, and the collar 13 cooperates with the shaft 33. Specifically, the fall arrest net body 12 is installed inside the protective frame 11, and the collar 13 is disposed at the edge of the protective frame 11.

[0046] In this embodiment, the protective frame 11 has a square structure. A collar 13 is installed on the side of the protective frame 11 near the mounting frame 30. The collar 13 is sleeved on the end of the shaft 33 and can rotate along the axis of the shaft 33, thereby driving the protective frame 11 and the fall arrest net body 12 to rotate. Bolts are provided on the side of the protective frame 11 away from the mounting frame 30, and the bolts are connected to the connectors 20.

[0047] Specifically, there are three collars 13, which are spaced apart along the length of the protective frame 11. The mounting crossbar 31 has a movable space, which allows the middle part of the shaft 33 to protrude, so that the middle part of the shaft 33 can cooperate with the collar 13 located in the middle position of the three collars 13.

[0048] It should also be noted that the fall protection net 10 also includes a guide rod 14, which is externally connected to the collar 13. The guide rod 14 cooperates with the drive member 40. The guide rod 14 is used to drive the collar 13 to rotate around the axis of the shaft 33 under the drive of the drive member 40, so that the fall protection net body 12 rotates relative to the mounting frame 30.

[0049] Specifically, the driving component 40 includes an electric push rod 41 and a connecting rod 42. The electric push rod 41 is mounted on the mounting vertical rod 32, and the connecting rod 42 is located at the bottom end of the electric push rod 41. The connecting rod 42 cooperates with the guide rod 14. The electric push rod 41 is mounted on the mounting vertical rod 32 via a mounting base. The electric push rod 41 moves up and down in the vertical direction, thereby driving the connecting rod 42 to move up and down, thus converting the linear motion of the connecting component 20 into the circular motion of the guide rod 14, ultimately realizing the opening and closing of the fall protection net 10.

[0050] Specifically, the guide rod 14 is provided with a movable groove 141, and the end of the connecting rod 42 is movably disposed in the movable groove 141.

[0051] During operation, when the electric push rod 41 is at its highest point, the fall protection net body 12 is in the open state. After the electric push rod 41 is started, it moves downward, thereby driving the connecting rod 42 to move downward. During the downward movement of the connecting rod 42, the guide rod 14 drives the collar 13 to rotate clockwise relative to the shaft 33, thereby retracting the fall protection net body 12. When the electric push rod 41 is at its lowest point, the fall protection net body 12 is in the retracted state.

[0052] In addition, the connector 20 is a connecting rope 21, with both ends of the connecting rope 21 connected to the fall arrest net 10 and the mounting frame 30, respectively. Specifically, one end of the connecting rope 21 is provided with a first connecting ring 211, which is rotatably engaged with the mounting frame 30. The other end of the connecting rope 21 is provided with a second connecting ring 212, which is bolted to the protective frame 11. The diameter of the first connecting ring 211 is larger than the diameter of the second connecting ring 212.

[0053] Furthermore, a limiting ring 35 is provided at the top of the mounting rod 32. After the first connecting ring 211 is connected to the top of the mounting rod 32, the limiting ring 35 can limit the first connecting ring 211, so that the connecting rope 21 and the mounting frame 30 are stably connected.

[0054] The length of the connecting rope 21 can be adjusted according to the open state of the fall protection net body 12, and no specific limit is made here.

[0055] The safety fall arrest device 100 provided in this embodiment has at least the following advantages:

[0056] Existing fall arrest devices are generally in the open state during use, and the fall arrest net is required to protect workers at heights. However, existing fall arrest devices suffer from the problem that the fall arrest net is inconvenient to retract, thus affecting normal work. To solve this technical problem, the safety fall arrest device 100 provided in this embodiment has a driving component 40 on the mounting frame 30 during use. The driving component 40 is connected to the fall arrest net 10, and the driving component 40 can drive the fall arrest net 10 to rotate relative to the mounting frame 30. This allows the fall arrest net 10 to be flexibly opened and retracted according to work needs. When the safety of construction workers needs to be protected, the driving component 40 drives the fall arrest net 10 to open quickly, and the connecting component 20 can position the fall arrest net 10 in the open position to further enhance the protective effect and avoid secondary injuries. When protection is not required, the driving component 40 drives the fall arrest net 10 to retract quickly, thereby reducing interference with normal work and making it convenient to use.

[0057] In summary, this utility model embodiment provides a safety fall arrest device 100, which includes a fall arrest net 10, a connector 20, a mounting frame 30, and a drive member 40. One end of the connector 20 is connected to the fall arrest net 10, and the other end of the mounting frame 30 is connected to the connector 20. The mounting frame 30 is also connected to the fall arrest net 10. The drive member 40 is disposed on the mounting frame 30 and is connected to the fall arrest net 10. The drive member 40 is used to drive the fall arrest net 10 to rotate relative to the mounting frame 30, so that the fall arrest net 10 opens or retracts. In use, the safety fall arrestor 100 has a drive unit 40 mounted on the mounting frame 30. The fall arrestor net 10 is mounted on the mounting frame 30 and connected to the drive unit 40. The drive unit 40 can drive the fall arrestor net 10 to rotate relative to the mounting frame 30, allowing the fall arrestor net 10 to open or retract. When the fall arrestor net 10 rotates to the open position following the drive unit 40, the connecting member 20 can limit the fall arrestor net 10, positioning it in the open position to protect the safety of construction workers. The fall arrestor net 10 can be flexibly opened and retracted through the drive unit 40, making it more convenient to use. Furthermore, the connecting member 20 further enhances the protective effect.
