Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the following embodiments, in conjunction with the accompanying drawings, will specifically illustrate the technical solution of this invention.

[0023] <Example>

[0024] like Figure 1 and Figure 2 As shown, this embodiment provides a protective net device for preventing collisions and falls, which includes: a hook 1, a fastening hook 2, a guide pulley 3, a bottom rope net 4, a rope net bag 5, a lightweight elastic filler 6, a hanging rope 7, and a tension rope 8.

[0025] See Figure 4 Several lightweight elastic fillers 6 are filled into the rope mesh bag 5. The rope mesh bag 5 is a nylon rope mesh bag, and its planar shape can be designed according to actual needs, such as square, round, polygonal, etc., preferably square. In this embodiment, for example... Figure 3 The illustration shows a square rope net bag. The lightweight elastic filler 6 is made of pearl cotton rods or pearl cotton blocks. Pearl cotton is lightweight, elastic, and tough. When pearl cotton rods are used as the lightweight elastic filler 6, the radial length of the cross-section of the pearl cotton rod is preferably set to 10cm to 20cm. The maximum axial length of a single pearl cotton rod can be set to a single strip equal to the side length of the rope net. If the axial length is too long, it can be divided into several sections for easy manual handling. When pearl cotton blocks are used as the lightweight elastic filler 6, the side length of the pearl cotton blocks is preferably set to 5cm to 10cm. The filling thickness of the lightweight elastic filler in the rope net bag 5 can also be set according to the impact protection requirements of the object under actual conditions: when the impact force of the object is large and a higher impact buffer protection requirement is required, a thicker filling thickness is set accordingly; when the impact force of the object is not so large, the filling thickness can be reduced accordingly.

[0026] The bottom rope net 4 is tied to the lower surface of the rope net bag 5, and the shape of the bottom rope net 4 matches that of the rope net bag 5. In this embodiment, the rope net bag is a square rope net bag, and the bottom rope net is a square rope net. The bottom rope net 4 is a nylon rope net. Figure 4 As shown, the bottom rope net 4 and the rope net bag 5 are connected by several nylon binding straps 10, and the connection points of the several nylon binding straps 10 are evenly distributed on the lower surface of the rope net bag 5.

[0027] The base rope net 4 has at least four main connection points distributed along its edge, each main connection point being connected to one hanging rope 7 and two tension ropes 8. Viewed from above, the two tension ropes connected to the same main connection point preferably form an angle of 60° to 120°. The base rope net 4 also has at least one secondary connection point between any two main connection points along its edge, each secondary connection point being connected to one hanging rope 7 and one tension rope 8. The base rope net 4 also has at least one central connection point in its middle section, each central connection point being connected to one hanging rope 7. In this embodiment, the four apex corners of the base rope net are designated as four main connection points, and each side has at least one secondary connection point, specifically as follows... Figure 2 As shown, two parallel sides each have two secondary connection points, the other two parallel sides each have one secondary connection point, and the middle section has two central connection points.

[0028] like Figure 1 and Figure 2 As shown, the bottom rope net 4 is laid out horizontally. Each hanging rope 7 is suspended by a hook 1, which is fixed to the main structure 9 and is higher than the preset laying position of the rope net bag 5 (i.e., above the preset laying position of the rope net bag). Each tension rope 8 is arranged around a guide pulley 3 and its end is connected to a hook. The guide pulley 3 and the hook are fixed to the main structure 9, and the installation position of the guide pulley 3 is lower than the preset laying position of the rope net bag 5 (i.e., below the preset laying position of the rope net bag). The hook 2 is located directly below the guide pulley 3. The preset laying position of the rope net bag is determined according to actual needs.

[0029] The main structure 9 refers to the existing structure in the actual installation environment of the anti-collision and anti-fall protection net device. For example, if the anti-collision and anti-fall protection net device needs to be installed in a production workshop, the main structure 9 can be the existing steel beam structure within the factory building; or, if the anti-collision and anti-fall protection net device needs to be installed in a laboratory, the main structure 9 can be the walls and ceiling of the laboratory building structure. In this embodiment, the main structure 9 shown in the attached drawings is a steel beam structure.

[0030] like Figure 5As shown, the hook component 1 in this embodiment includes a J-shaped hook body 11, an upper nut 12, and a lower nut 13. The upper end of the hook body 11 is provided with external threads, and corresponding holes are drilled in the steel beam structure. The hook body 11 is connected to the upper nut 12 and the lower nut 13 to fix the hook component 1 to the steel beam structure.

[0031] like Figure 6 As shown, the hook 2 in this embodiment includes a J-shaped hook body 21, a base plate 22, a bolt 23, and a nut 24. The hook body 21 is welded to the base plate 22 to form an integral part. The base plate 22 and the steel beam structure are drilled with corresponding holes. The base plate 22 is connected to the bolt 23 and the nut 24 to fix the hook 2 to the steel beam structure.

[0032] In this embodiment, when the main structure 9 is a steel beam structure, the structure of hook 1 and hook 2 is illustrated, but this is not a limitation. When the main structure 9 is the wall and ceiling of a building structure, hook 1 and hook 2 are both constructed by welding hook body 21 to base plate 22 to form an integral structure, which can be driven into the building structure by expansion bolts.

[0033] See Figure 1 and Figure 2 This embodiment provides a collision and fall protection net device installed at a high altitude, suitable for preventing collisions when objects are launched upwards. However, this is not a limitation; the same collision and fall protection net device can also be installed at a low altitude, suitable for preventing collisions when objects fall from a height. Figure 1 The anti-collision and anti-fall protective net device shown has the bottom rope net 4 and rope net bag 5 in an untensioned state. Then, the tension rope is pulled up from below the guide pulley 3 and the end of the tension rope is tied to the hook 2, as shown. Figure 2 As shown, the bottom rope net 4 and rope net bag 5 are in a taut state. At this time, the bottom rope net 4, rope net bag 5 and lightweight elastic filler provide impact-resistant cushioning force to prevent ejected or falling objects from hitting the protected wall or the protected object.

[0034] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention are included within the scope of protection of the present invention.
