Description

Technical Field

[0001] This utility model belongs to the field of engineering protection net technology, specifically, it relates to a safety engineering protection net structure. Background Art

[0002] Safety nets must be used during construction, especially for high-rise buildings. Safety nets with a specified mesh density must be installed to ensure the safety of construction workers, prevent parts or objects from falling from high-rise buildings, and ensure the safety of the ground near the construction site. Further measures are needed to ensure construction safety.

[0003] Existing protective nets are mostly connected by simple rope binding or ordinary buckle connection. Rope binding is prone to loosening during long-term use, especially under the action of external forces such as vibration and wind, which may cause gaps to appear in the protective net and endanger the protected objects. Although ordinary buckle connection is relatively more secure, the buckles are prone to deformation and breakage when subjected to greater tension or impact, which will damage the stability of the overall structure of the protective net.

[0004] Limited overall stability: Some protective nets, after installation, are prone to overall displacement, swaying, or even collapse under complex stress environments such as strong winds and earthquakes due to their unreasonable structural design. For example, some simple slope protection nets rely on only a few anchor points for fixation. When heavy rain causes soil to loosen or strong winds occur, they cannot effectively resist external forces, and the protective effect is greatly reduced. In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a safety engineering protective net structure that can overcome or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: a safety engineering protective net structure, including a connecting frame, and multiple tension toothed plates slidably connected to the connecting frame. A fastening disc is slidably connected to the tension toothed plate, and the fastening disc passes through the middle of the tension toothed plate. A rotating shaft is engaged on the tension toothed plate. Multiple bidirectional screws are rotatably connected to the connecting frame, and a drill rod and a drill bit are fixedly connected to the bidirectional screws. A bearing sleeve and a threaded seat are symmetrically and reciprocally slidably arranged on the bidirectional screws. A connecting rod is rotatably connected to the bearing sleeve, and a barb is fixedly connected to the connecting rod.

[0007] Furthermore, a limiting plate is fixedly connected to the fastening plate, a rotating shaft is rotatably connected through the limiting plate, and a rotating wheel is fixedly connected to the rotating shaft.

[0008] Furthermore, the tension toothed plate is Z-shaped, with one end of the tension toothed plate near the rotating wheel located on the periphery of the fastening disc, and the other end of the tension toothed plate having teeth that mesh with the rotating shaft.

[0009] Furthermore, protective net frames are fixedly installed on the two sets of connecting frames. The protective net frames are provided with multiple grids, which are fitted onto the tension toothed plate.

[0010] Furthermore, a bearing sleeve is slidably connected to the upper end of the bidirectional screw, a threaded seat is slidably connected to the lower end of the bidirectional screw, and a drill bit is fixedly connected to the drill rod.

[0011] Furthermore, multiple elastic support rods are fixedly connected to the threaded seat, and connecting rods are fixedly connected to the elastic support rods. The connecting rods are connected to the threaded seat through the elastic support rods.

[0012] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: the rotating shaft of the present invention drives the bottom tension tooth plate to retract, the tension tooth plate pulls the mesh on the protective net frame to tighten the mesh, effectively preventing loosening caused by vibration, wind and other factors, and greatly improving the reliability and safety of the protective net connection.

[0013] The bearing sleeve moves downward, causing it to move downward as well. At this time, the connecting rod opens outward and is subjected to inward force. The connecting rod drives the barb inward, and the barb grips the ground tightly, enhancing the stability of the protective net on the ground surface. This allows the protective net to effectively resist external forces from different directions, such as strong winds, earthquakes, and slope soil sliding.

The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0022] Example: Refer to Figures 1-4 A safety engineering protective net structure includes a connecting frame 1, and multiple tension toothed plates 2 slidably connected to the connecting frame 1. A fastening disc 21 is slidably connected to the tension toothed plate 2, and the fastening disc 21 passes through the middle of the tension toothed plate 2. A rotating shaft 23 is engaged on the tension toothed plate 2. Multiple bidirectional screws 4 are rotatably connected to the connecting frame 1. A drill rod 46 and a drill bit 47 are fixedly connected to the bidirectional screws 4. A bearing sleeve 41 and a threaded seat 44 are symmetrically and reciprocally slidably arranged on the bidirectional screws 4. A connecting rod 42 is rotatably connected to the bearing sleeve 41, and a barb 43 is fixedly connected to the connecting rod 42.

[0023] A limiting plate 22 is fixedly connected to the fastening plate 21, and a rotating shaft 23 is rotatably connected through the limiting plate 22. A rotating wheel 24 is fixedly connected to the rotating shaft 23.

[0024] The tension toothed plate 2 is "Z" shaped. One end of the tension toothed plate 2 near the rotating wheel 24 is set on the periphery of the fastening plate 21, and the other end of the tension toothed plate 2 is provided with teeth that mesh with the rotating shaft 23.

[0025] A protective net frame 3 is fixedly installed on the two sets of connecting frames 1. The protective net frame 3 is provided with multiple grids, which are fitted onto the tension tooth plate 2.

[0026] The upper end of the bidirectional screw 4 is slidably connected to a bearing sleeve 41, the lower end of the bidirectional screw 4 is slidably connected to a threaded seat 44, and a drill bit 47 is fixedly connected to the drill rod 46.

[0027] Multiple elastic support rods 45 are fixedly connected to the threaded seat 44, and a connecting rod 42 is fixedly connected to the elastic support rod 45. The connecting rod 42 is connected to the threaded seat 44 through the elastic support rod 45.

[0028] When in use, align the mesh on the protective net frame 3 with the tension toothed plate 2, then rotate the rotating wheel 24. The rotating wheel 24 drives the rotating shaft 23 to rotate synchronously. The rotating shaft 23 drives the tension toothed plate 2 at the bottom to contract. The tension toothed plate 2 pulls the mesh on the protective net frame 3 to tighten the mesh, effectively preventing loosening caused by vibration, wind and other factors, and greatly improving the reliability and safety of the protective net connection.

[0029] A small motor inside the equipment or manual rotation of the drill rod 46 drives the drill bit 47 to rotate and drill into the ground. At the same time, the double-headed screw 4 on the drill rod 46 rotates, the bearing sleeve 41 on the double-headed screw 4 moves downward, and the threaded seat 44 moves upward. The threaded seat 44 drives the elastic support rod 45 upward, and the elastic support rod 45 provides upward support to the connecting rod 42. Meanwhile, the bearing sleeve 41 moves downward, causing the connecting rod 42 to open outward and be subjected to inward force. The connecting rod 42 drives the barb 43 inward, and the barb 43 firmly grips the ground, enhancing the stability of the protective net on the ground surface and enabling the protective net to effectively resist external forces from different directions, such as strong winds, earthquakes, and slope soil sliding.

[0030] The rotating shaft 23 of this utility model drives the bottom tension tooth plate 2 to retract, and the tension tooth plate 2 pulls the mesh on the protective net frame 3 to tighten the mesh, effectively preventing loosening caused by vibration, wind and other factors, and greatly improving the reliability and safety of the protective net connection.

[0031] The bearing sleeve 41 moves downward, causing the connecting rod 42 to open outward and be subjected to inward force. The connecting rod 42 drives the hook 43 inward, which firmly grips the ground, enhancing the stability of the protective net on the ground surface and enabling the protective net to effectively resist external forces from different directions, such as strong winds, earthquakes, and slope soil sliding.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
