Technical Field
[0001] This utility model relates to the technical field of building fall protection devices, specifically a fall protection device for building construction. Background Technology
[0002] In construction, fall arrestors are crucial equipment for ensuring worker safety. They prevent workers from falling while working at heights, primarily by improving worker safety, reducing accident risks, and increasing construction efficiency. They effectively prevent workers from falling due to slips or accidents, reducing the risk of personal injury, protecting workers' lives, and significantly decreasing the incidence of accidents caused by falls. This improves the overall safety level of the construction site, creates a safer working environment, enhances workers' sense of security, and thus increases their work enthusiasm and efficiency, contributing to improved team morale.
[0003] Patent document CN219993209U discloses a fall arrest device for safe construction, comprising a bracket, with sliding rods slidably connected to the front and rear sides of one side of the bracket, two sliding rods respectively fixedly connected to the front and rear sides of one side of a support rod, grooves provided in the middle of the two sliding rods, and reinforcing ribs fixedly connected inside the two sliding rods, the bottom surface of the bracket and the bottom surface of the support rod respectively fixedly connected to the top of the net, upper retaining rings rotatably connected to the distal sides of the lower retaining rings on both sides, and first bolts threadedly connected to the proximal sides of the two upper retaining rings. In this invention, by providing grooves in the middle of the two sliding rods, the two sliding rods are made into hollow structures, and reinforcing ribs are provided inside the two sliding rods. This can improve the structural strength of the two sliding rods, thus preventing the device from bending due to impact when stretched too much. However, the aforementioned safety construction fall protection device mainly focuses on improving the structural strength of the two sliding rods to prevent bending due to impact when stretched too much, but it does not consider increasing the support area. Excessive construction materials will easily occupy the work area, resulting in limited operating space. This situation not only causes congestion at the construction site, but may also affect construction efficiency and safety. Disorganized material stacking will narrow the passage, restrict worker movement, thereby delaying the project progress and increasing the risk of accidents. Therefore, it is necessary to develop a fall protection device for construction. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1 to 4A fall arrestor for construction work includes a base plate 1, a protective frame 2 fixedly installed on top of the base plate 1, an intercepting net 3 fixedly installed on the protective frame 2, a storage groove 5 inside the base plate 1, a load-bearing plate 6 inside the storage groove 5, an adjusting component inside the storage groove 5, and square slots 12 arranged in an array inside the load-bearing plate 6. Storage boxes 15 are installed inside the square slots 12, and a guiding component is installed inside the storage groove 5. When constructing high-rise buildings, the fall arrestor supports workers and prevents accidental falls. An electric motor is installed on the building, connected to a lifting ring 4 via a traction rope system, which drives the raising and lowering of the fall arrestor. The base plate 1 provides a working space for workers, and the protective frame 2 and intercepting net 3 protect workers from accidental falls. To achieve the purpose of preventing falls, when the fall arrest device is used in construction, the position of the load-bearing plate 6 is adjusted by the adjustment component when the support area is increased. After the load-bearing plate 6 moves from the storage groove 5 to the outside, the storage box 15 is placed inside the square groove 12 and the position of the storage box 15 is limited. At the same time, the storage box 15 can support and store the workpieces during construction, thereby increasing the support area. This can effectively distribute the load applied to the structure, reduce the pressure per unit area, help reduce local stress concentration in materials, reduce the risk of collapse or damage, provide a larger contact surface, thereby enhancing the stability of the overall structure and reducing the possibility of overturning or sliding. Especially in extreme situations such as poor soil conditions or earthquakes, it provides workers with a safer working environment and reduces the risk of accidents.
[0022] Please see Figure 1 and Figure 2 A lifting ring 4 is fixedly installed on the protective frame 2. The lifting ring 4 has a through hole. After the traction rope is connected to the lifting ring 4, the electric motor can adjust the height of the fall arrest device for construction by winding or unwinding the traction rope.
[0023] Please see Figure 3 The adjustment assembly includes a threaded cylinder 7, a threaded rod 8, and a drive motor 9. The drive motor 9 is fixedly installed inside the storage slot 5, the threaded cylinder 7 is fixedly installed inside the load-bearing plate 6, and the threaded rod 8 is threadedly connected inside the threaded cylinder 7. One end of the threaded rod 8 is fixedly connected to the output end of the drive motor 9. A battery assembly and a controller are installed on the side of the fall arrestor for construction. Both the battery assembly and the controller are electrically connected to the drive motor 9, which can control the drive motor 9 to rotate the threaded rod 8. When the threaded rod 8 rotates, it will adjust the position of the load-bearing plate 6 through the threaded cylinder 7, thereby facilitating the adjustment of the support area to support the object.
[0024] Please see Figure 3The guiding assembly includes a guide cylinder 10 and a guide rod 11. The guide cylinders 10 are arranged in an array inside the load-bearing plate 6. The guide rod 11 passes through the guide cylinders 10 and one end of the guide rod 11 is fixedly connected to the storage groove 5. When the load-bearing plate 6 moves, it will drive the guide cylinders 10 to slide on the guide rod 11. The guide cylinders 10 and the guide rod 11 cooperate to guide the load-bearing plate 6, so that the load-bearing plate 6 moves smoothly.
[0025] Please see Figure 3 and Figure 4 A magnetic plate 13 is arranged around the inside of the square groove 12, and a magnetic suction plate 16 is arranged around the storage box 15. The bottom of the storage box 15 is symmetrically provided with limiting holes 17, and a positioning rod 14 is inserted through the limiting hole 17. One end of the positioning rod 14 is fixedly connected to the square groove 12. When the storage box 15 is placed inside the square groove 12, the limiting hole 17 is fitted onto the positioning rod 14, which will limit the position of the storage box 15. At the same time, the magnetic plate 13 and the magnetic suction plate 16 cooperate to limit the position of the storage box 15. The storage box 15 facilitates the storage of work materials.
[0026] Working principle: Firstly, during the construction of high-rise buildings, a construction fall arrestor is used to support workers and prevent accidental falls. An electric motor is installed on the building, connected to the lifting ring 4 via a traction rope system, which drives the raising and lowering of the construction fall arrestor. The base plate 1 provides a working space for workers, and the protective frame 2 and the intercepting net 3 protect workers from accidental falls, achieving the purpose of fall prevention. When the construction fall arrestor is in operation, increasing the support area causes the drive motor 9 to rotate the threaded rod 8. The rotation of the threaded rod 8, through the threaded cylinder 7, adjusts the position of the load-bearing plate 6. After the load-bearing plate 6 moves from the storage slot 5 to the outside, it is stored... After the box 15 is placed inside the square groove 12, the limiting hole 17 is fitted onto the positioning rod 14, which limits the position of the storage box 15. At the same time, the magnetic plate 13 and the magnetic suction plate 16 cooperate to limit the position of the storage box 15. The storage box 15 can support and store the workpiece materials of the construction operation, thereby increasing the support area. It can effectively distribute the load applied to the structure, reduce the pressure per unit area, help reduce local stress concentration of materials, reduce the risk of collapse or damage, provide a larger contact surface, thereby enhancing the stability of the overall structure and reducing the possibility of overturning or slippage. Especially in extreme situations such as poor soil conditions or earthquakes, it provides workers with a safer working environment and reduces the risk of accidents.
