Description

Technical Field

[0001] This application relates to the field of protective nets, and more particularly to a protective net device. Background Technology

[0002] Safety netting is one of the safety protection facilities at racetracks. Its main function is to prevent debris from flying out of the track's protected area and injuring spectators after a vehicle accident. Safety netting systems generally consist of posts, connecting ropes, and reinforcing wire mesh fencing. The posts support the netting, which blocks debris and provides protection. However, existing safety netting systems use channel steel and I-beams for the posts, which have limited strength and are prone to deformation and breakage. Furthermore, some safety netting systems have zigzag joints between the extension and the main body, welded together; when the safety netting system is subjected to excessive tensile force, the posts are prone to breakage and deformation.

[0003] Therefore, it is necessary to provide an improved protective netting device to solve the above problems. Utility Model Content

[0021] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0022] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0023] See Figure 1 As shown, this application provides a protective net device, including multiple steel pipe posts 10, multiple connecting ropes 20, and a protective net 30. The multiple steel pipe posts 10 are arranged vertically. The multiple connecting ropes 20 are horizontally connected between the multiple steel pipe posts 10. The multiple steel pipe posts 10 are arranged at intervals along the length of the connecting ropes 20. The protective net 30 is fixed to the multiple connecting ropes 20, and the protective net 30 blocks debris splashed from the racetrack, thus providing protection. The multiple steel pipe posts 10 and connecting ropes 20 provide support and fixation for the protective net 30.

[0024] See Figure 2 As shown, each steel pipe column 10 includes a main body 101 and an extension 102 extending obliquely upward from the main body 101. The main body 101 is straight, and the extension 102 is curved. The main body 101 and the extension 102 are integrally formed by cold bending, avoiding welding joints, improving overall strength and resistance to bending and torsion, while the curved design of the extension 102 is more aesthetically pleasing. Furthermore, cold bending requires low temperature, requires no heating, and can be completed directly at room temperature, making it simple to operate and suitable for mass production.

[0025] According to other embodiments of this application, the main body 101 and extension 102 of the steel pipe column 10 can also be integrally formed by casting process.

[0026] According to the embodiments of this application, the steel pipe column 10 is a circular steel pipe with a cavity inside. The diameter of the steel pipe column 10 is 8cm, and the wall thickness is 2mm. The distance between two adjacent steel pipe columns 10 is less than or equal to 4m. In some other embodiments, the steel pipe column 10 may also have a square or other polygonal cross-section.

[0027] The extension 102 forms an angle α with the horizontal plane, and the angle α is 45°. The height of the extension 102 is greater than or equal to 20cm and less than or equal to 40cm. Specifically, the extension 102 extends towards the track direction, and the extension 102 forms an angle of 45° with the track plane. The extension 102 increases the total height of the protective net device by at least 20cm, which can effectively expand the protective area and intercept high-speed flying debris.

[0028] The plurality of steel pipe columns 10 includes a first column 11, a second column 12, and a plurality of third columns 13 disposed between the first column 11 and the second column 12. The first column 11, the second column 12, and the plurality of third columns 13 are all vertically arranged. The first column 11, the plurality of third columns 13, and the second column 12 are spaced apart along the length of the connecting rope 20.

[0029] According to the embodiments of this application, the number of third columns 13 can be increased or decreased according to actual needs. The arrangement of the columns can be adjusted to other forms. By setting the first column 11, the second column 12 and multiple third columns 13, a uniformly distributed support structure is formed, enhancing the stability of the protective netting device.

[0030] In some embodiments, the protective netting device only has a first post 11 and a second post 12, and by reducing the interval between the first post 11 and the second post 12, a third post 13 is not provided in the middle.

[0031] See Figure 3 As shown, the connecting rope 20 is connected to the first post 11, the second post 12, and a plurality of third posts 13 via fasteners 40. According to an embodiment of this application, the connecting rope 20 is a steel wire rope, specifically, the connecting rope 20 may be a galvanized steel wire rope.

[0032] In some implementations, when the race car speed is less than or equal to 80 km / h, the diameter of the connecting rope 20 is 8 mm. When the race car speed is greater than 80 km / h and less than or equal to 160 km / h, the diameter of the connecting rope 20 is 10 mm. When the race car speed is greater than 160 km / h and less than or equal to 240 km / h, the diameter of the connecting rope 20 is 12 mm. When the race car speed is greater than 240 km / h, the diameter of the connecting rope 20 is 15 mm.

[0033] According to the embodiment of this application, the tension of the connecting rope 20 is 500 kg / cm. 2 .

[0034] The protective net 30 has a plurality of mesh openings 31, the horizontal and vertical dimensions of which are both less than or equal to 90 mm, which can effectively intercept small-sized fragments and improve the protective effect. In some embodiments, the mesh openings 31 can be circular, rectangular, rhomboid, elliptical, or other shapes.

[0035] In the embodiments of this application, the mesh 31 is diamond-shaped. The protective net 30 can be connected to the connecting rope 20. In some embodiments, the two ends of the protective net 30 can be connected by the connecting rope 20 for tensioning, or the connecting rope 20 can be passed through the mesh 31 and tensioned to make the protective net 30 taut.

[0036] According to an embodiment of this application, the protective net 30 is fixed to the connecting rope 20 by a plurality of clamps 80. The plurality of clamps 80 on the connecting rope 20 between the main body portions 101 of the steel pipe column 10 are spaced 1m apart. The spacing between the plurality of clamps 80 on the connecting rope 20 between the extension portions 102 of the steel pipe column 10 is less than or equal to 0.5m.

[0037] According to the embodiments of this application, the protective net 30 is a wire mesh, specifically a galvanized wire mesh. The diameter of the wire in the protective net 30 is greater than or equal to 4 mm. The protective net 30 should be on the side of the fence closest to the racetrack.

[0038] Fastener 40 includes turnbuckles 41 and U-shaped fasteners 42. Both ends of the connecting rope 20 are fixed to the first post 11 and the second post 12 via turnbuckles 41. The connection rope 20 is also fixed to the first post 11 and the second post 12 via turnbuckles 41, facilitating adjustment of the tension of the connecting rope 20 and ensuring the tension and stability of the protective net 30.

[0039] In some implementations, the turnbuckle 41 can be replaced with other fasteners, such as clips or bolt-nut combinations.

[0040] The connecting rope 20 is fixed to the third column 13 by a U-shaped fastener 42. Each third column 13 has two vertically arranged connecting holes 131, and the U-shaped fastener 42 is assembled into the two connecting holes 131. The connecting rope 20 passes through the U-shaped fastener 42 to fix the connecting rope 20 to the third column 13. The design of the U-shaped fastener 42 and the connecting holes 131 makes the fixation between the connecting rope 20 and the third column 13 more secure, preventing the connecting rope 20 from loosening or falling off.

[0041] According to other embodiments of this application, the U-shaped fastener 42 can be replaced with other fasteners, such as ring buckles or clips. The number and arrangement of the connecting holes 131 can also be adjusted according to the actual design.

[0042] The protective netting device also includes multiple column bases 50, multiple support bases 60, and multiple tie rods 70. The multiple column bases 50 are respectively located at the bottom of the first column 11, the second column 12, and multiple third columns 13. The column bases 50 are concrete structures, specifically C30 concrete bases. The column bases 50 are buried to a depth of 90cm. The design of the column bases 50 enhances the stability of the steel pipe columns 10, preventing them from tilting or collapsing due to external forces. One end of the first column 11, the second column 12, and the multiple third columns 13 protrudes into the multiple column bases 50. The depth to which the first column 11, the second column 12, and the multiple third columns 13 are buried in the column bases 50 is 70cm.

[0043] According to other embodiments of this application, the column base 50 may take other forms, such as pre-embedded steel plates or anchor bolts.

[0044] A support base 60 is located between the first column 11 and the second column 12. The support base 60 is close to the column base 50. One end of the diagonal brace 70 is connected to the support base 60, and the other end of the diagonal brace 70 is connected to either the first column 11 or the second column 12. The support base 60 and the diagonal brace 70 further enhance the stability of the overall structure, especially under strong winds or external impacts, effectively preventing the protective netting 30 from deforming or being damaged.

[0045] In some embodiments, the diagonal brace 70 intersects with the first column 11, the second column 12 and a plurality of third columns 13, and the angle between the diagonal brace 70 and the steel pipe column 10 is in the range of 30° to 60°.

[0046] According to other embodiments of this application, the tie rod 70 can be replaced with other support structures, such as a transverse support rod or a tie rope.

[0047] The protective netting device is installed behind the crash barrier 90, and the distance between the protective netting device and the crash barrier 90 is 1m.

[0048] The protective netting device of this application is equipped with multiple steel pipe columns 10. The steel pipe columns 10 have high strength and are not easily deformed or broken. At the same time, the design of the main body 101 and its extension 102 of the steel pipe column 10 eliminates weld seams on the steel pipe column 10, resulting in better overall integrity and higher resistance to bending and torsion.
