Description

Technical Field

[0001] This utility model relates to a suspended slide facility. Background Technology

[0002] Ziplining, also known as a zip line, is a newly emerging recreational activity. Passengers wearing harnesses are suspended from a sliding trolley, using a slanted steel cable as a track, and rely on gravity to slide rapidly from a high point to a low point. Ziplining is a thrilling and exciting activity that can easily cross obstacles such as valleys, rivers, and lakes, giving passengers the novel experience of soaring through the air, making it very popular with tourists, especially young people.

[0003] Chinese patent CN109224465A discloses a zipline system that is easy to install and erect, comprising: two load-bearing steel cables, several fixed steel cables, a clamp trolley, a track, and several "U"-shaped steel cable clamps. The two load-bearing steel cables are arranged in parallel, with both ends fixed to two fixed points with a certain height difference. Several steel cable clamps are provided on each load-bearing steel cable from beginning to end, with equal spacing between clamps, and the clamps on the two load-bearing steel cables are positioned identically and corresponding to each other. The two ends of each fixed steel cable are fixed to a pair of corresponding steel cable clamps on the two load-bearing steel cables. The middle section of the fixed steel cable is used to hook onto the track. The clamp trolley is set on the track to support personnel sliding on the track. The advantages of this invention are: 1. It uses standard parts, replacing welding with assembly, reducing costs, simplifying processing and erection, and facilitating later maintenance and replacement; 2. The overall weight of the parts is reduced, making it easier to transport and adaptable to installation in more complex terrains.

[0004] Traditional zipline systems are mostly used between simple or small structures. Their design and installation are relatively straightforward, typically achieved through a single steel cable connecting two fixed points. The length of traditional ziplines is limited by terrain conditions and the distance between the fixed points, making it difficult to meet the requirements for ultra-long distances.

Utility Model Content

[0006] The present invention aims to provide an ultra-long cableway that is attached to an elevated bridge to achieve a longer operating distance, while also being relatively easy to install.

[0007] The ultra-long cableway attached to the high-altitude bridge in this scheme includes a manned hoist, a clamp trolley, and a track cable that are connected together. The clamp trolley slides along the track cable, the manned hoist is suspended below the clamp trolley, and a sling is connected to the track cable to suspend the track cable on the bridge. The lower end of the sling is connected to the track cable, and the upper end of the sling is equipped with a fixing device. The clamp on the fixing device fixes the sling to the bridge.

[0008] Beneficial effects:

[0009] Achieving ultra-long-distance coverage: By utilizing the existing structure of large bridges, such as the main span of their truss structures, this system can achieve ultra-long-distance zipline laying distances far exceeding those of traditional ziplines. This not only expands the application range of ziplines but also provides users with a brand-new long-distance rapid transportation or sightseeing experience. The ultra-long zipline offers a unique aerial perspective and a thrilling gliding experience, becoming a major attraction for tourists.

[0010] Simplified installation and maintenance: Utilizing the bridge itself as a supporting frame reduces the need for additional intermediate support structures, lowering installation complexity and cost. The clamp design in the fixing device ensures a quick and secure connection between the slings and the bridge.

[0011] Environmentally friendly: Compared to building new ground transportation infrastructure, this system minimizes the impact on the natural environment. It does not require large-scale land development and avoids damage to the ecological environment, aligning with modern sustainable development principles.

[0012] In summary, the ultra-long zipline system provided by this invention, with its superior design and technical advantages, achieves ultra-long-distance coverage while ensuring the system's safety, reliability, and ease of maintenance, adding new value and functionality to high-altitude bridges, and is particularly suitable for applications in tourism, rescue, and other fields.

[0013] Furthermore, two or more slings are connected at the same node of the track cable. This redundant design fully ensures the safety of the equipment, making it less likely to cause an accident even if one of them fails. At the same time, multiple slings can better maintain the spatial stability of the entire system.

[0014] Furthermore, the same node of the track cable is connected to two inverted V-shaped suspension cables.

[0015] Furthermore, the fixing device includes a base plate and a gripper, with the gripper hinged to the base plate.

[0016] Furthermore, both jaws on the substrate are provided with through holes, and the two through holes are connected after the two jaws are engaged.

[0017] Furthermore, the substrate has an H-shaped cross-section. Attached Figure Description

[0018] Figure 1 This is a schematic diagram of an embodiment of the present utility model.

[0019] Figure 2 for Figure 1 Enlarged view of part A in the middle. Detailed Implementation

[0020] The present invention will be further described in detail below through specific embodiments:

[0021] The reference numerals in the accompanying drawings include: track cable 1, sling 2, fixing device 3, base plate 31, gripper 32, bolt 33, and winch 34.

[0022] The basic implementation examples are as follows: Figure 1 , 2 As shown:

[0023] The track cable is composed of multiple high-strength steel strips connected together to form a circular track beneath the main span of the bridge. One end of the circular track can be fitted with a single, reciprocating track. The entire track can be over 3 kilometers long and is laid along the main span of the bridge. The clamp trolley is designed to slide smoothly on the track cable. For example, multiple rollers are installed on the clamp trolley, with rollers clamping the track cable in various directions (top and bottom) to ensure the clamp trolley can run on the track cable. A safe and reliable personnel lifting device is provided below to carry passengers or goods. The clamp trolley has automatic locking and unlocking functions, ensuring quick fixing or release at any position. The track cable, clamp trolley, and personnel lifting device in this solution all utilize mature existing technologies.

[0024] Multiple inclined suspension cables are evenly distributed along the entire length of the track cable. The lower end of each suspension cable is directly connected to the track cable. The two suspension cables at each node form an inverted V shape, and the upper end of the suspension cables is connected to the bridge through a specially designed fixing device.

[0025] The fixing device consists of a base plate, grippers, fixing holes, bolts, and a winch. The base plate, serving as the foundation platform for the entire device, is primarily made of H-beams and hinged with two openable L-shaped grippers. These grippers can close and firmly hold the lower chord of the bridge truss or pre-embedded perforated lugs, etc. The grippers have horizontal through holes, forming through fixing holes after the grippers close, allowing bolts to be inserted to further lock the grippers in place and prevent accidental loosening.

[0026] The base plate is also equipped with a rotatable winch, which is horizontally hinged to the upper surface of the base plate. One end of the sling passes through a hole in the center of the base plate and is securely connected to the circumference of the winch. By rotating the winch, the effective length of the sling can be precisely adjusted, thereby adjusting the height and flatness of the track cable and ensuring the optimal operating condition of the cableway system. The winch can be fixed to the base plate with a pin to prevent rotation and can remain stable after the sling length adjustment is completed.

[0027] Installation Process: During installation, first determine the positions of all slings and accurately install the fixing devices on the designated truss nodes or additional structures. Use a winch to adjust the tension of each sling, maintaining the track cable at an appropriate tension—neither too slack nor too taut. Finally, test the sliding performance of the clamp trolley along the entire track cable to ensure smooth and unobstructed movement.

[0028] Maintenance and Inspection: To ensure the long-term stable operation of the system, regular inspections and maintenance of all components are necessary, paying particular attention to the wear of the grippers, the tightness of the bolts, and the working condition of the winch. In addition, the condition of the track cable must be monitored, and any problems discovered, such as surface damage or signs of corrosion, should be addressed promptly.

[0029] The above description is merely an embodiment of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the scope of this utility model, and these should also be considered within the protection scope of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
