Description

Technical Field

[0001] This utility model belongs to the field of bridge platform structure, and particularly relates to a net array platform attached to a high-altitude bridge. Background Technology

[0002] High-altitude net courses, as an emerging project that combines challenge, fun, and physical fitness, have been enthusiastically received by adventure enthusiasts. This activity creates a thrilling and challenging adventure route by carefully designing and constructing various complex and varied obstacles between towering steel or wooden pillars.

[0003] Traditional high-altitude netting systems are typically located in relatively flat, enclosed environments, such as outdoor adventure parks or large sports fields, to ensure participant safety and facilitate rescue efforts. However, with the increasing pursuit of extreme experiences, the design concept of combining high-altitude netting systems with high-altitude bridges has emerged, aiming to provide a more thrilling and exciting adventure experience while making full use of existing bridge structures and minimizing environmental impact.

[0004] However, the design of net array platforms attached to high-altitude bridges faces numerous technical challenges and safety hurdles. First, high-altitude bridges are often situated on complex and varied terrain, significantly affected by wind. This necessitates that the net array platform possess excellent wind resistance to ensure stability under various climatic conditions. The design must fully consider the dynamic characteristics of the bridge structure and rationally arrange the support structure of the net array platform to effectively disperse and resist wind forces. Second, in the event of an accidental fall from a high-altitude net array, especially if a player experiences a sudden physical condition preventing self-rescue, external rescue is extremely difficult due to the height and unique environment. Utility Model Content

[0005] This invention provides a net array platform suitable for high-altitude bridges that can effectively disperse wind force and reduces the difficulty of rescue operations.

[0006] The present invention provides a net array platform attached to an elevated bridge, comprising a platform body and a cable-stayed structure. The platform body includes several columns, the upper ends of which are fixedly connected to the truss at the bottom of the elevated bridge. Side wall protective nets are arranged between adjacent columns. The cable-stayed structure includes cable ropes that diagonally connect the lower ends of the columns to the truss. Rescue nets are arranged between adjacent cable ropes and between the lower ends of the cable ropes. A rescue passage is provided between the rescue nets and the protective nets. A pulley mechanism is provided above the rescue nets, and the free end of the rope of the pulley mechanism is connected to a lifting basket. A platform for the lifting basket to dock is provided on the columns.

[0007] The beneficial effects are as follows: The protective net formed by the uprights, through the diagonal fixing of the lower ends of the uprights, forms a stable triangular structure, enhancing the stability of the platform body, effectively dispersing the impact of wind on the platform, and improving wind resistance. Simultaneously, a rescue net is arranged between the diagonal ropes, creating a rescue space outside the protective net. Furthermore, active escape and rescue channels are designed to address the needs of tourists. For example, if a tourist falls from the protective net and enters the rescue net, if conscious, they can climb back into the protective net via the rescue channel. If they are disoriented or unable to save themselves, rescuers can descend into the rescue net via the rescue channel, place the tourist in the lifting basket, and activate the pulley mechanism to raise the lifting basket to the docking platform. This dual setup of the rescue net and the protective net provides additional safety for participants, reducing the risk of accidental falls. At the same time, the rescue channel and pulley mechanism, combined with the design of the lifting basket, enable rapid rescue in emergencies, reducing rescue difficulty and improving rescue efficiency.

[0008] In summary, this utility model disperses the wind force on the platform body by using inclined ropes, and at the same time takes into account the actual difficulties of high-altitude rescue by designing a rescue net and supporting rescue facilities, thereby improving rescue efficiency.

[0009] Furthermore, transfer platforms are installed on the pillars, with varying heights for each platform. Climbing stairs, zip lines, or plank bridges connect adjacent transfer platforms, forming play routes. The transfer platforms increase the diversity and challenge of the play experience, while the varying heights of the platforms allow for more flexible and varied routes. The design of climbing stairs, zip lines, or plank bridges enriches the play experience and enhances the platform's fun factor.

[0010] Furthermore, the rescue channel is cylindrical, with its lower end connected to the rescue net and having an entrance, and its upper end connected to the transfer platform. This cylindrical design facilitates a smoother rescue process and reduces obstacles during rescue operations. The connection between the rescue channel and the transfer platform provides rescuers with a convenient rescue route, further improving rescue efficiency.

[0011] Furthermore, the upper end of the column is threadedly connected to the truss and secured to the truss with steel wire rope. This dual fixing method of threaded connection and steel wire rope securing improves the stability and safety of the connection between the column and the truss. This connection method facilitates installation and disassembly, reducing maintenance costs.

[0012] Furthermore, the rescue net is designed to form an inverted frustum shape, which allows it to better cover the main body of the platform, improving the coverage and safety of the rescue operation. This design also facilitates the arrangement of the rescue net and guy ropes, making the entire platform structure more compact and aesthetically pleasing.

[0013] Furthermore, the rescue net is a different color from the protective net. This makes the rescue net more visually noticeable, facilitating quick identification and use in emergency situations. This design also helps improve the platform's aesthetics and recognizability, making it more attractive. Attached Figure Description

[0016] like Figure 1 As shown, the mesh platform attached to the elevated bridge includes a main body consisting of four columns 1. The upper ends of the columns 1 are fixedly connected to the truss at the bottom of the elevated bridge. Specifically, threaded holes can be made in the truss, and the upper ends of the columns 1 are connected to the truss using high-strength bolts, which serve a positioning and connection function. To strengthen the connection, radial through holes are made at the upper ends of the columns 1, through which steel wire ropes pass and are then tied to the truss. Through holes can also be made at different heights on the columns 1 to prevent the column 1 from detaching from the truss if a steel wire rope breaks.

[0017] After the four columns 1 are connected to the truss, bottom protective nets 3 and side wall protective nets 3 between the columns 1 are installed at the lower ends of the four columns 1, forming the main frame of the rectangular platform. Within the main frame, horizontal transfer platforms 2 are installed on the columns 1. The height of the transfer platforms 2 varies between different columns 1. Climbing stairs, zip lines, plank bridges, or climbing nets are built between adjacent transfer platforms 2 to form play passages. An accessible continuous protection system is also designed along the play passage. This system consists of protective ropes installed along the play passage and sliding locks attached to the protective ropes. Visitors are connected to the sliding locks via short ropes; when a visitor moves, the sliding locks move along the protective ropes.

[0018] Around the outer perimeter of the platform's main frame, each column 1 has a through hole at its lower end (the height of the through hole is lower than the height of the bottom protective net 3). A guy rope 4 passes through this through hole and is tied to the truss. Rescue nets 5 are arranged between adjacent guy ropes 4 and between the bottoms of the guy ropes 4, thus forming an inverted frustum-shaped overall rescue net 5 around the outer perimeter of the platform's main frame. A rescue passage 6 is provided between this rescue net 5 and the highest transfer platform 2. This rescue passage 6 is a cylindrical passage composed of steel pipes and rope netting. The lower end of the rescue passage 6 connects to the rescue net 5 and has an entrance, while the upper end connects to the transfer platform 2 and has an exit.

[0019] To rescue unconscious tourists, a pulley mechanism 8 is installed on the bottom truss of the bridge corresponding to rescue net 5. The pulley mechanism 8 includes a pulley connected to a winch and a rope wound in the pulley groove. The fixed end of the rope is connected to the pulley, and the free end is connected to the lifting basket 7. When the winch is started, the pulley rotates and can lift the lifting basket.

[0020] The transfer platform 2, which is closest to the pulley mechanism 8, can be used as a rescue platform. For efficient rescue, the transfer platform 2 can be extended as close as possible to the lifting path of the lifting basket 7. Alternatively, a lifting port can be provided on the transfer platform 2, through which the lifting basket 7 passes during lifting. Or, a separate docking platform can be installed on the column 1 for the lifting basket 7 to park.

[0021] The rescue net 5 and the protective net are made of different colors, and the mesh diameter of the rescue net 5 is smaller than that of the protective net.
