Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a steel wire safety net fixing device for a horizontal reserved opening in a building. Background Technology

[0002] In the construction industry, horizontal openings are typically covered with square timber and surrounded by steel pipe edge protection. This method presents numerous safety hazards, as most openings are exposed to direct sunlight or the elements, making the timber prone to excessive deflection or corrosion, which can also lead to safety risks. Furthermore, it fails to meet the requirements of long construction periods and frequent overlapping operations, thus compromising safety measures. Utility Model Content

[0003] The purpose of this invention is to overcome the problems mentioned in the background art and to provide a steel wire safety net fixing device for horizontal reserved openings in buildings. This device is more convenient to operate and can improve safety.

[0004] The objective of this utility model is mainly achieved through the following technical solutions:

[0005] A steel wire safety net fixing device for a horizontal reserved opening in a building includes a hollow support rail with openings at both ends and the top. A connecting mechanism is installed at the bottom of the support rail, and this connecting mechanism can slide along the support rail. Several support shafts are arranged in the cavity of the support rail, with gears installed on the foremost and rearmost support shafts, and support wheels fitted on the remaining support shafts. A main chain, connected end-to-end, is arranged in the cavity, with the gears and support wheels located within the area formed by the main chain and meshing with it. A guide beam is installed at the top of the support rail, and the guide beam can slide along the support rail. One end of the guide beam forms a hook, and a secondary chain is fixed to the top of the guide beam. A controller and a transmission device are installed at the top of the support rail; the controller meshes with the main chain, and the transmission device meshes with both the main chain and the secondary chain. Currently, horizontal reserved openings in the construction field are typically covered with square timber and protected by steel pipe edges. There are many potential safety hazards. Most of the reserved openings are exposed to the sun or in the open air, and the timber is prone to excessive deflection or corrosion, which can lead to safety risks. It also cannot meet the requirements of long construction periods and frequent cross-operations, which reduce the need for safety measures. To address the aforementioned issues, this solution proposes a steel wire safety net fixing device for pre-reserved openings in buildings. The device includes a hollow support rail with openings at both ends and the top. The support rail serves as both a support component and a container for installation. A connecting mechanism is located at the bottom of the support rail and can slide along it, facilitating installation and fixation of the device on structural beams at different locations. Several support shafts are installed within the cavity of the support rail. Gears are mounted on the foremost and rearmost support shafts, while support wheels are fitted onto the remaining support shafts. A main chain, connected end-to-end, is located within the cavity. The gears and support wheels are positioned within the area formed by the main chain, and the gears mesh with the main chain. The support wheels lift and transport the central main chain, while the rotation of the gears drives the main chain. A guide beam is installed at the top of the support rail and can slide along it. A hook is formed at one end of the guide beam, and a secondary chain is fixed to the top of the guide beam. A controller and a transmission device are installed at the top of the support rail. The controller meshes with the main chain, and the transmission device meshes with both the main chain and the secondary chain. The controller controls the rotation of the main chain, and the transmission device transmits the rotation of the main chain to the secondary chain, thereby causing the guide beam to move. It is connected to the wire mesh through a hook, which enables flexible operation and meets the requirements for dragging and fixing wire mesh with large-sized reserved openings, reducing labor costs and providing safety measures for installation.

[0006] Furthermore, the connecting mechanism includes an L-shaped connecting plate. The top of the connecting plate is recessed to form a mounting groove, and the symmetrical sidewalls of the support rail are recessed to form guide grooves. The support rail is positioned within the mounting groove, and the sidewalls of the mounting groove engage with the guide grooves. The connecting plate can move along the guide grooves. This design enables the connecting mechanism to move relative to the support rail. Furthermore, a locking bolt is provided on the connecting plate, with its top passing through the connecting plate and located below the support rail. The locking bolt can move on the connecting plate. This achieves the fixation between the support rail and the corresponding structural beam, ensuring precise positioning of the device during use and preventing displacement.

[0007] Furthermore, the controller includes two mounting plates, each fixed to the top surface of the support rail. A connecting shaft is positioned between the mounting plates, passing through them and rotating around its own axis. A control gear is fitted onto the outer wall of the connecting shaft, meshing with the main chain. A handle is connected to the connecting shaft. The operator grips the handle, causing the connecting shaft to rotate, which in turn drives the control gear, causing the meshed main chain to rotate. This allows the transmission device meshing with the main chain to rotate.

[0008] Furthermore, the transmission includes two mounting plates, both fixed to the top surface of the support rail. A connecting shaft is positioned between the mounting plates, passing through them and rotating around its own axis. A transmission gear 1 and a transmission gear 2 are fitted onto the outer wall of the connecting shaft, with the transmission gear 1 positioned between the transmission gear 2. The transmission gear 1 meshes with the main chain, and the transmission gear 2 meshes with the secondary chain. The transmission gear 1 on the transmission is driven by the main chain to rotate, causing the connecting shaft 2 to rotate, which in turn drives the transmission gear 2 to rotate, causing the secondary chain to move. Since the secondary chain and the guide beam are connected as a whole, this causes the guide beam to move horizontally, thus moving the hook and pulling the wire mesh. Once in position, the movement stops, and the gears lock the position.

[0009] Furthermore, the top of the support track is recessed to form a groove, and the bottom of the guide beam is raised to form a slide rail. The slide rail is inserted into the groove and can move along the groove. By designing the combination of slide rail and groove, the sliding trajectory of the guide beam can be controlled to ensure that its movement trajectory is on the same straight line, thus maintaining stability when dragging the wire mesh.

[0010] In summary, compared with the prior art, this utility model has the following advantages: the connection mechanism slides along the support track, which facilitates the installation of the device on structural beams at different positions and forms a fixed position. The controller controls the rotation of the main chain, and the transmission device transmits the rotation of the main chain to the secondary chain, thereby moving the guide beam. The device is connected to the wire mesh through the hook, which enables flexible operation, meets the requirements of dragging and fixing wire mesh in large-size reserved openings, reduces labor costs, and provides safety measures for installation.

[0019] like Figure 1 and Figure 2As shown in this embodiment, a steel wire safety net fixing device for a horizontal reserved opening in a building includes a hollow support rail 17 with openings at both ends and the top. The support rail 17 serves as a support component and a container for installation. A connecting mechanism is provided at the bottom of the support rail 17, and the connecting mechanism can slide along the support rail 17. This facilitates the installation of the device on structural beams at different locations and provides fixation. The connecting mechanism includes an L-shaped connecting plate, which is composed of a horizontal plate 13 and a vertical plate 15. The bottom of the horizontal plate 13 is vertically fixed to the top of the vertical plate 15, forming an L-shape. The top of the vertical plate 15 is recessed to form an installation groove, and the symmetrical sidewalls of the support rail 17 are recessed to form guide grooves 16. The support rail 17 is placed in the installation groove, and the sidewalls of the installation groove are engaged in the guide grooves 16. The connecting plate can move along the guide grooves 16. Through this design, the connecting mechanism can move relative to the support rail 17. A locking bolt 14 is provided on the horizontal plate 13, and the top of the locking bolt 14 passes through the horizontal plate 13 and is located below the support rail 17. The locking bolt 14 can move on the horizontal plate 13. When it is necessary to fix the device to the corresponding structural beam 12, move the device close to the corresponding structural beam 12 and move the connecting mechanism until the structural beam 12 is located in the area formed by the horizontal plate 13, the vertical plate 15 and the support rail 17. Tighten the locking bolt 14 to press the locking bolt 14 against the bottom of the structural beam 12. At this time, the top of the structural beam 12 and the bottom of the support rail 17 are in contact, thus fixing the device to the structural beam 12. At the same time, in order to prevent damage to the structure, it is best to put a gasket on the locking bolt 14 and the bottom of the structural beam 12.

[0020] Multiple support shafts 18 are installed in the cavity of the support track 17. Gears are installed on the foremost and rearmost support shafts 18, and support wheels are fitted on the remaining support shafts 18. A main chain 1 connected end to end is arranged in the cavity, and the gears and support wheels are all located within the area formed by the main chain 1, with the gears meshing with the main chain 1. The support wheels lift the middle part of the main chain 1 and form a rotation mechanism, while the rotation of the gears drives the main chain 1 to rotate.

[0021] The top opening of the support rail 17 has grooves on both sides, and the bottom of the guide beam 9 protrudes to form a slide rail. The slide rail is inserted into the groove and can move along the groove, allowing the guide beam 9 to slide along the support rail 17. By designing the combination of slide rail and groove, the sliding trajectory of the guide beam 9 can be controlled, ensuring that its movement trajectory is on a straight line, thus maintaining stability when dragging the wire mesh. A hook 8 is formed at one end of the guide beam 9, and a secondary chain 7 is fixed to the top of the guide beam 9. A controller and a transmission device are installed on the top of the support rail 17. The controller engages with the main chain 1, and the transmission device engages with both the main chain 1 and the secondary chain 7. The controller controls the rotation of the main chain 1, and the transmission device transmits the rotation of the main chain 1 to the secondary chain 7, thereby moving the guide beam 9. It is connected to the wire mesh through the hook 8, which enables flexible operation, meets the requirements for dragging and fixing wire mesh with large-sized reserved openings, reduces labor costs, and provides safety measures for installation.

[0022] The controller includes two mounting plates 2, both fixed to the top surface of the support rail 17. A connecting shaft 1 is provided between the mounting plates 2, passing through the mounting plates 2 and capable of rotating around its own axis. A control gear 3 is fitted on the outer wall of the connecting shaft 1, and the control gear 3 meshes with the main chain 1. A handle 4 is connected to the connecting shaft 1. The operator grips the handle 4 to rotate the connecting shaft 1, thereby driving the control gear 3 to rotate, causing the main chain 1 meshing with it to rotate, thus realizing the rotation of the transmission device meshing with the main chain 1.

[0023] The transmission device includes two mounting plates 11, both fixed to the top surface of the support rail 17. A connecting shaft 10 is positioned between the mounting plates 11, passing through them and rotating around its own axis. A transmission gear 5 and a transmission gear 6 are fitted onto the outer wall of the connecting shaft 10, with the transmission gear 5 positioned between the transmission gears 6. The transmission gear 5 meshes with the main chain 1, and the transmission gears 6 mesh with the secondary chain 7. The transmission gear 5 rotates under the drive of the main chain 1, causing the connecting shaft 10 to rotate, which in turn rotates the transmission gears 6, causing the secondary chain 7 to move. Since the secondary chain 7 and the guide beam 9 are connected as a whole, the guide beam 9 moves horizontally, causing the hook 8 to move. This allows the wire mesh to be pulled and moved until it reaches its designated position, where the gears lock in place.

[0024] This solution enhances safety measures, is simple to operate, highly flexible, and allows for the dragging and fixing of wire mesh in large-sized pre-reserved openings, reducing labor costs and providing safety measures for installation. It also meets the installation requirements for large-sized horizontal pre-reserved openings, increases the protection standards for the edges of the openings, and provides wire mesh protection measures inside the openings, reducing potential safety hazards.
