Description

Technical Field

[0001] This invention belongs to the field of suspension transportation technology, specifically relating to a tethered balloon lifting suspension transportation device and transportation method. Background Technology

[0002] With the deepening development of power grid construction, overhead transmission line projects are increasingly passing through mountainous areas with complex terrain and harsh environments. Due to strict ecological and environmental protection requirements, conventional material transportation equipment is difficult to effectively overcome complex terrain obstacles and cannot meet the material transportation needs of construction in mountainous areas.

[0003] Tethered balloons, with their significant advantages such as long hovering time, large coverage area, low energy consumption, and environmental friendliness, can solve the problem of material transportation in environmental protection areas and harsh mountainous conditions. Chinese patent document CN105539806A discloses a suspended balloon cableway transportation device. This device uses a support frame at the mountaintop and an anchoring mechanism at the foot of the mountain, employing a load-bearing rope to construct a transportation route. The tethered balloon is slidably connected to the load-bearing rope via a pulley system. Material transportation is achieved by pulling the tethered balloon with a traction rope and a traction machine, forming an upward parabolic transportation route to avoid mountain obstacles. Although the pulley system reduces friction when the tethered balloon travels on the load-bearing rope, the device still requires the tethered balloon to perform ascent, movement, descent, and empty return trips each time it is used to transport materials.

[0004] Existing material transport methods using tethered balloons have the following drawbacks: each transport operation requires a process including the balloon's ascent, movement, descent, and empty return trip. This process results in a low percentage of effective transport time for the tethered balloons, leading to low material transport efficiency and severely limiting their application value in mountainous conditions. Therefore, there is an urgent need to develop a new tethered balloon transport method to improve transport efficiency, optimize the operation process, and reduce empty return trip time. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, and addressing the current situation where tethered balloon transportation requires frequent ascent, movement, descent, and empty return trips, resulting in low effective transportation time and low transportation efficiency, this invention provides a tethered balloon lifting suspension transportation device, comprising: Lifting equipment is used for lifting and transporting materials; The suspension cable is fixedly connected to the lifting device; The first retraction mechanism is located at the first loading and unloading point and is connected to one end of the suspension cable; The second retraction mechanism is located at the second loading and unloading point and is connected to the other end of the suspension cable; The tethered balloon is connected to the ground via a first cable and a second cable. The third deployment and retraction mechanism is connected to the tethered balloon and to the lifting device via a third cable. The first and second deployment and retraction mechanisms can move the lifting device between the first and second loading / unloading points by coordinating the deployment and retraction of the suspension cable; the third deployment and retraction mechanism can utilize the tethered balloon to bear the weight of the material by controlling the deployment and retraction of the third cable.

[0006] Optionally, it may also include a fourth and a fifth deployment mechanism; The tethered balloon is connected to the fourth deployment and take-up mechanism via the first cable, and to the fifth deployment and take-up mechanism via the second cable. The coordinated deployment and take-up of the fourth and fifth deployment and take-up mechanisms enables the vertical and lateral movement of the tethered balloon.

[0007] Optionally, the fourth deployment and retraction mechanism is located on one side of the first loading and unloading point, and the fifth deployment and retraction mechanism is located on one side of the second loading and unloading point. The fourth and fifth deployment and retraction mechanisms are respectively deployed corresponding to the first and second loading and unloading points, and can directly utilize the ground anchor fixing structure of the loading and unloading points without the need to add additional fixing points, thus reducing the amount of construction work. At the same time, it can form symmetrical traction on the tethered balloon from the two loading and unloading points, avoiding unilateral force displacement of the tethered balloon and ensuring that it is stably located in the working area above the suspension cable.

[0008] Optionally, the first take-up and release mechanism includes a first traction machine and a first drum, with one end of the suspension cable passing through the first traction machine and then wound around the first drum; The second winding mechanism includes a second traction machine and a second drum. The other end of the suspension cable passes through the second traction machine and is then wound onto the second drum. The first and second traction machines can independently adjust the tension of the suspension cable. The first and second drums are only responsible for storing the suspension cable, thus avoiding fluctuations in the winding and unwinding speed of the drums from affecting the stability of the suspension cable tension.

[0009] Optionally, the first loading / unloading point is located in a lower altitude area, and the second loading / unloading point is located in a higher altitude area. The first and second traction machines adjust the tension of the suspension cable to avoid ground obstacles during material transportation. By adjusting the tension of the suspension cable to change the sag of the loading / unloading points at different altitudes, ground obstacles can be flexibly avoided, ensuring the safety of material transportation.

[0010] Optionally, the lifting device is fixedly connected to the suspension cable via a sling gripper. The upper end of the lifting device has a lifting hole for connecting to the third cable, and the lower end of the lifting device has a hook for lifting materials. The sling gripper connection method ensures that the lifting device and the suspension cable are firmly fixed, preventing them from separating during transportation, and facilitates disassembly, assembly, and position adjustment. The structural design of the lifting hole and hook enables a reliable connection between the lifting device, the third cable, and the materials.

[0011] Based on the same inventive concept, the present invention also provides a tethered balloon lifting suspension transport method, comprising the following steps: The locations of the first and second loading / unloading points were determined based on the terrain of the mountainous area. A first take-up and release mechanism is set up at the first loading and unloading point, and a second take-up and release mechanism is set up at the second loading and unloading point. A drone is used to deploy the suspension cable from the first loading and unloading point to the second loading and unloading point, so that one end of the suspension cable passes through the first traction machine of the first take-up and release mechanism and is wound around the first drum, and the other end passes through the second traction machine of the second take-up and release mechanism and is wound around the second drum. At the first loading and unloading point, the third deployment and take-up mechanism is installed at the lower end of the tethered balloon, and one end of the third cable is connected to the third deployment and take-up mechanism, and the other end is connected to the lifting hole at the upper end of the lifting device. The lifting device is then fixedly connected to the suspension cable through the sling gripper. A fourth deployment mechanism is set up at the first loading and unloading point, and a fifth deployment mechanism is set up at the second loading and unloading point. The fourth and fifth deployment mechanisms are anchored by burying ground anchors. The tethered balloon is connected to the fourth deployment mechanism through the first cable and to the fifth deployment mechanism through the second cable. The fourth and fifth deployment mechanisms are activated to deploy the first and second cables in coordination. The third deployment mechanism releases the third cable simultaneously, so that the tethered balloon rises vertically from the first loading and unloading point until it reaches the preset working height. The fifth take-up and release mechanism is activated to wind up the second cable, while the third take-up and release mechanism simultaneously releases the third cable, causing the tethered balloon to move to the corresponding position above the suspension cable. Depending on transportation needs, materials are hoisted onto the hook at the lower end of the lifting device at either the first or second loading / unloading point. The third deployment mechanism is then activated to wind up the third cable, utilizing a tethered balloon to support the weight of the materials. The first and second deployment mechanisms work together to deploy and retract the suspension cable, enabling the lifting device and materials to move towards the target loading / unloading point. Based on the tethered balloon, the third deployment mechanism can control the deployment and retraction of the third cable to utilize the tethered balloon to support the weight of the materials. Deploying the suspension cable via drone eliminates the need for construction access, reducing damage to vegetation in mountainous areas, and offering high deployment efficiency while lowering construction difficulty.

[0012] Optionally, the following steps are also included: At the first loading and unloading point, the materials to be transported are attached to the hook at the lower end of the spreader; The third deployment mechanism is activated to wind up the third cable. The buoyancy of the tethered balloon, combined with the tension of the third cable, lifts the lifting device and materials upwards, with the tethered balloon bearing the weight of the materials. The first deployment mechanism releases the suspension cable, while the second deployment mechanism simultaneously winds it up, driving the spreader and material along the cable from the first loading / unloading point to the second. During the spreader's movement from the first loading / unloading point to the corresponding position below the tethered balloon, the third deployment mechanism simultaneously winds up the third cable. As the spreader continues its movement from below the tethered balloon to the second loading / unloading point, the third deployment mechanism simultaneously releases the third cable. This dynamic deployment and retraction design of the third cable allows for real-time adjustment of tension based on the spreader's position, ensuring effective use of the tethered balloon to support the material's weight. The coordinated deployment and retraction of the suspension cable by the first and second deployment mechanisms, along with the deployment and retraction of the third cable, ensures smooth material transport and prevents abnormal acceleration or deceleration of the spreader due to changes in terrain slope.

[0013] Optionally, the following steps are also included: After unloading materials at the second loading / unloading point, the first retraction mechanism is activated to wind up the suspension cable, while the second retraction mechanism simultaneously releases the cable, driving the spreader to move along the cable from the second loading / unloading point to the first. During the spreader's movement from the second loading / unloading point to the corresponding position below the tethered balloon, the third retraction mechanism simultaneously winds up the third cable. Similarly, during the spreader's continued movement from the corresponding position below the tethered balloon back to the first loading / unloading point, the third retraction mechanism simultaneously releases the third cable. When the spreader returns empty, there is no need to move the tethered balloon, significantly shortening the return trip time and improving overall transportation efficiency. The simultaneous winding and unwinding of the third cable during the return trip ensures stability and reliability, reducing operational risks.

[0014] Optionally, the following steps are also included: After all materials have been transported, the fifth deployment mechanism is activated to release the second cable, causing the tethered balloon to return to above the first loading and unloading point. The fourth deployment mechanism is activated to wind up the first cable, and the third deployment mechanism simultaneously winds up the third cable, causing the tethered balloon to descend to the ground and be anchored. The process involves dismantling the connection between the lifting device and the suspension cable, the third cable, and then recovering the lifting device, the suspension cable, the tethered balloon, the first and second deployment mechanisms, the first and second cables, the third and third deployment mechanisms, the fourth and fifth deployment mechanisms. The suspension cable is recovered using a drone. After transportation, the tethered balloon returns and anchors in an orderly manner according to the established procedures, preventing movement or damage caused by external factors such as wind, thus ensuring equipment safety. The use of drones for suspension cable recovery ensures an orderly recovery process and minimizes disruption to the site environment.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The tethered balloon lifting suspension transport device provided by this invention includes: a lifting device for lifting materials; a suspension cable fixedly connected to the lifting device; a first deployment and take-up mechanism located at a first loading / unloading point and connected to one end of the suspension cable; a second deployment and take-up mechanism located at a second loading / unloading point and connected to the other end of the suspension cable; a tethered balloon connected to the ground via a first cable and a second cable; and a third deployment and take-up mechanism connected to the tethered balloon and connected to the lifting device via a third cable. This invention utilizes the buoyancy of the tethered balloon in conjunction with the tension of the third cable to effectively utilize the tethered balloon to bear the weight of the materials, reducing wear and deformation of the suspension cable and extending its service life. Based on this invention, there is no need for the tethered balloon to simultaneously rise, move, descend, and return with the materials; material transport can be achieved solely through the coordinated deployment and take-up of the suspension cable by the first and second deployment and take-up mechanisms, significantly simplifying the operation process, increasing the effective transport time ratio, and significantly improving transport efficiency. The suspension cable and tethered balloon collaborative structure in this invention can effectively adapt to complex mountainous terrain, eliminating the need to create construction channels or build scaffolding in intermediate obstruction areas. Only the relevant mechanisms need to be deployed at the loading and unloading points, reducing damage to mountain vegetation and soil and meeting ecological environmental protection requirements. The fixed connection between the lifting device and the suspension cable in this invention, combined with the coordinated control of the deployment and retrieval mechanism, ensures the stability and safety of the material transportation process.

[0022] Example 1 like Figures 1-5 As shown, a tethered balloon-lifted suspension transport device includes: Lifting device 1 is used for lifting and transporting materials; Suspension cable 2 is fixedly connected to lifting device 1; The first retraction mechanism 3 is located at the first loading and unloading point and is connected to one end of the suspension cable 2; The second retraction mechanism 4 is located at the second loading and unloading point and is connected to the other end of the suspension cable 2. Tethered balloon 5 is connected to the ground via first cable 6 and second cable 7; The third launching and retracting mechanism 8 is connected to the tethered balloon 5 and is connected to the lifting device 1 via the third cable 9.

[0023] In specific implementation, the lifting device 1 is fixedly connected to the suspension cable 2. One end of the suspension cable 2 is connected to the first retraction mechanism 3 set at the first loading and unloading point, and the other end of the suspension cable 2 is connected to the second retraction mechanism 4 set at the second loading and unloading point. The first retraction mechanism 3 and the second retraction mechanism 4 can move the lifting device 1 between the first loading and unloading point and the second loading and unloading point by coordinating the retraction and release of the suspension cable 2. The tethered balloon 5 is connected to the ground through the first cable 6 and the second cable 7. The tethered balloon 5 is connected to the third retraction mechanism 8. The third retraction mechanism 8 is connected to the lifting device 1 through the third cable 9. The weight of the material can be effectively utilized by controlling the retraction and release of the third cable 9.

[0024] The first and second launching mechanisms 3 and 4 can be equipped with traction machines, drums, or winches, or a tractor vehicle with relevant components can be selected according to the needs of the scenario. For example, in narrow sloping areas, a small winch can be used as the launching mechanism; in valleys with loose soil, a traction machine or tractor vehicle can be used in conjunction with ground anchors to enhance stability. The third launching mechanism 8 can be a winch or a hoist.

[0025] The specific selection of the first and second loading / unloading points can be flexibly chosen based on the actual terrain conditions, such as... Figures 1-4 As shown, for example, the first loading and unloading point is located on a plain at the foot of a mountain (e.g., at an altitude of 200 meters), and the second loading and unloading point is located in a construction area at the top of a mountain (e.g., at an altitude of 800 meters), with farmland, forests, and loess slopes in between. Material 12 is loaded at the first loading and unloading point and transported to the second loading and unloading point via the device, achieving low-to-high transport, or vice versa. Specifically, before transport, the first and second deployment mechanisms 3 and 4 work together to tension the suspension cable 2, and the tethered balloon 5 is fixed at a suitable height by the first cable 6 and the second cable 7. After loading, the third deployment mechanism 8 winds up the third cable 9, using the buoyancy of the tethered balloon 5 to lift the lifting device 1 and material 12 upwards. Subsequently, the first deployment mechanism 3 releases the suspension cable 2, and the second deployment mechanism 4 winds up the suspension cable 2, driving the lifting device 1 to move along the suspension cable 2 towards the second loading and unloading point, completing the transport.

[0026] like Figure 5 As shown, for example, the first and second loading / unloading points are located on two separate mountain peaks (both at an altitude of approximately 600 meters), separated by a deep valley. Materials can be loaded at the first loading / unloading point and unloaded at the second, depending on the construction schedule.

[0027] The suspension cable 2 can be made of high-strength flexible materials (such as nylon reinforced fiber rope) to meet the tensile requirements of complex terrain; the fixed connection between the lifting device 1 and the suspension cable 2 can adopt an anti-detachment grip structure to ensure a stable connection during transportation; the airbag of the tethered balloon 5 can be made of puncture-resistant composite fabric to improve adaptability to the field environment.

[0028] This invention enables the tethered balloon 5 to remain tethered for an extended period of time. The buoyancy of the tethered balloon 5 can be used to lift the material 12, continuously providing net buoyancy for the transportation of the material 12. By combining the tethered balloon 5 with the suspension cable 2, the suspension cable 2 is pulled by the first deployment mechanism 3 and the second deployment mechanism 4, and the length of the third cable 9 is controlled by the third deployment mechanism 8. This drives the lifting device 1 to move along the direction of the suspension cable 2, realizing the transfer of the material 12 from the first loading and unloading point to the second loading and unloading point, and realizing the transfer of the material 12 at low altitude.

[0029] This invention enables the tethered balloon 5 to remain anchored for extended periods during transport without frequent lifting and lowering, thereby simplifying operations, improving transport efficiency, reducing damage to trees and vegetation, and lowering construction compensation costs.

[0030] This invention enables the connection of the suspension cable 2, the tethered balloon 5, and the material 12 through the lifting device 1, and the coordinated movement of the lifting device 1 and the suspension cable 2 through the cable gripper, realizing the transportation of materials and empty return trip. This device reduces the transportation steps of traditional tethered balloons, can realize multiple material transportation, improve transportation efficiency, and reduce the labor intensity and operation risk of construction workers.

[0031] In existing technologies, tethered balloons need to move synchronously with the materials, resulting in a low effective transportation time. Each transport requires a complete process of ascent, movement, descent, and return. Based on this invention, the tethered balloon 5 can remain tethered for extended periods during transport. The lifting device 1 is moved only through the coordinated deployment of the first and second deployment mechanisms 3 and 4. The third deployment mechanism 8 adjusts the length of the third cable 9 to effectively utilize the tethered balloon 5 to bear the weight of the materials, eliminating the need for frequent movement of the tethered balloon 5 and significantly increasing the effective transportation time. For example, when transporting 10 batches of materials, existing technologies require 10 complete ascent and descent round trips, while this invention requires only one deployment of the tethered balloon 5, with subsequent transport completed solely through the movement of the lifting device 1, resulting in a significant improvement in efficiency. Furthermore, for scenarios with limited installation space on slopes, soft soil, and the need to protect the natural environment, this invention only requires the deployment of deployment mechanisms at the first and second loading / unloading points, eliminating the need for construction in intermediate obstruction areas (mountains, farmland, forests, etc.), thus avoiding environmental damage. For example, in loess slope areas, deployment can be completed simply by deploying the suspension cable 2 using a drone, without the need for road excavation or scaffolding. The deployment and retrieval of the third cable 9 can effectively utilize the tethered balloon 5 to bear the weight of the materials, reducing wear and deformation of the suspension cable 2 and extending its service life.

[0032] Existing technologies have never proposed a combination of "tethered balloon fixation + suspension cable traction + cable adjustment". This invention changes the core logic of synchronous movement of tethered balloons and materials in existing technologies by using the synergy of the three, and constructs a completely new transportation architecture.

[0033] Furthermore, it also includes a fourth receiving and releasing mechanism 10 and a fifth receiving and releasing mechanism 11; The tethered balloon 5 is connected to the fourth launch and take-up mechanism 10 via the first cable 6, and to the fifth launch and take-up mechanism 11 via the second cable 7.

[0034] In practice, the tethered balloon 5 is connected to the fourth deployment and take-up mechanism 10 via the first cable 6 and to the fifth deployment and take-up mechanism 11 via the second cable 7. The coordinated deployment and take-up of the fourth deployment and take-up mechanism 10 and the fifth deployment and take-up mechanism 11 enables the vertical and horizontal movement of the tethered balloon 5.

[0035] The tethered balloon 5 can adopt a main and auxiliary airbag structure. The main airbag is filled with helium to provide the main buoyancy, while the auxiliary airbag is filled with air. By adjusting the amount of air in the auxiliary airbag, the buoyancy can be finely adjusted to ensure stable net buoyancy. The tethered balloon 5 is connected to the fourth deployment and take-up mechanism 10 via the first cable 6 and to the fifth deployment and take-up mechanism 11 via the second cable 7. The two work together to achieve vertical and lateral movement. When the fourth deployment and take-up mechanism 10 and the fifth deployment and take-up mechanism 11 simultaneously deploy the first cable 6 and the second cable 7, the tethered balloon 5 can rise vertically under the action of buoyancy; when the fourth deployment and take-up mechanism 10 and the fifth deployment and take-up mechanism 11 simultaneously retract the first cable 6 and the second cable 7, the tethered balloon 5 can descend vertically under the action of cable tension.

[0036] By keeping the cable length of one of the four deployment mechanisms 10 and 11 constant, while the other mechanism winds up the cable, the tethered balloon 5 can move laterally. For example, if the tethered balloon 5 needs to move laterally from above the first loading / unloading point to above the middle section of the suspension cable 2, the fourth deployment mechanism 10 keeps the length of the first cable 6 constant, while the fifth deployment mechanism 11 winds up the second cable 7. Under the action of lateral tension, the tethered balloon 5 moves to the target position. Since the length of the first cable 6 remains constant, its height will decrease accordingly as the tethered balloon 5 moves laterally, but this decrease in height will not affect the stability of the transport.

[0037] Specifically, universal joints can be installed at the connection points of the first cable 6 and the second cable 7 with the tethered balloon 5 to prevent the tethered balloon 5 from shifting due to cable tension; a pressure regulating valve can be equipped on the auxiliary air bladder of the tethered balloon 5 to adjust the air pressure in real time according to changes in ambient temperature and material weight, maintaining stable net buoyancy. The fourth and fifth deployment mechanisms 10 and 11 can be specifically selected from equipment such as traction winches, hoists, and winches.

[0038] Furthermore, the fourth receiving and unloading mechanism 10 is located on one side of the first loading and unloading point, and the fifth receiving and unloading mechanism 11 is located on one side of the second loading and unloading point.

[0039] In practice, taking a first loading / unloading point at the foot of the mountain (e.g., at an altitude of 200 meters) and a second loading / unloading point at the top of the mountain (e.g., at an altitude of 800 meters) as an example, the fourth deployment / retrieval mechanism 10 is fixed to a ground anchor near the first loading / unloading point, and the fifth deployment / retrieval mechanism 11 is fixed to a ground anchor near the second loading / unloading point. After the tethered balloon 5 rises to a height of 500 meters, the fifth deployment / retrieval mechanism 11 winds up the second cable 7, while the fourth deployment / retrieval mechanism 10 maintains the length of the first cable 6, allowing the tethered balloon 5 to move from above the first loading / unloading point to above the suspension cable 2.

[0040] The fourth and fifth deployment mechanisms 10 and 11 correspond to the loading and unloading points and can utilize ground anchors or other fixing structures at these points, eliminating the need for additional fixing points elsewhere and reducing construction work. Simultaneously, the first cable 6 and the second cable 7 pull the tethered balloon 5 from both sides of the loading and unloading points, creating symmetrical tension and preventing unilateral displacement of the tethered balloon 5. The fourth deployment mechanism 10 can limit the vertical movement distance of the tethered balloon 5 via the first cable 6 to prevent excessive ascent; the fifth deployment mechanism 11 can limit the horizontal movement distance via the second cable 7, ensuring that the tethered balloon 5 remains within the working area above the suspension cable 2 and avoids exceeding the safe range.

[0041] Furthermore, the first take-up and release mechanism 3 includes a first traction machine 301 and a first drum 302, with one end of the suspension cable 2 passing through the first traction machine 301 and then winding around the first drum 302; The second take-up and release mechanism 4 includes a second traction machine 401 and a second drum 402. The other end of the suspension cable 2 passes through the second traction machine 401 and is then wound around the second drum 402.

[0042] In practice, the first traction machine 301 and the second traction machine 401 are responsible for adjusting the tension and moving speed of the suspension cable 2, while the first drum 302 and the second drum 402 are responsible for storing the suspension cable 2. During material 12 transportation, the first traction machine 301 and the second traction machine 401 can operate synchronously (at the same speed but in opposite directions) to make the suspension cable 2 move at a uniform speed, driving the lifting device 1 from the first loading / unloading point to the second loading / unloading point. During this process, the first drum 302 and the second drum 402 simultaneously wind up and unwind the suspension cable 2. The traction machines and drums operate separately, allowing the traction machines to independently adjust the tension of the suspension cable 2, while the drums are only responsible for storage, thus avoiding fluctuations in the winding / unwinding speed of the drums from affecting the stability of the suspension cable 2's tension.

[0043] Furthermore, the first loading and unloading point is located in a low-altitude area, and the second loading and unloading point is located in a high-altitude area. The first traction machine 301 and the second traction machine 401 adjust the tension of the suspension cable 2 to enable the material 12 to avoid obstacles on the ground during transportation.

[0044] In practical implementation, for example, if the first loading / unloading point is located in a low-altitude area (e.g., 300 meters) and the second loading / unloading point is located in a high-altitude area (e.g., 900 meters), and the suspension cable 2 is tilted, the first traction machine 301 and the second traction machine 401 can adjust the output torque to change the tension of the suspension cable 2, thereby adjusting the sag of the suspension cable 2 and avoiding obstacles on the ground. Furthermore, based on the above design, the sag of the suspension cable 2 can be flexibly adjusted according to the terrain environment, shortening the transportation path of the lifting device 1 and improving efficiency while ensuring obstacle avoidance. For example, a larger sag can be maintained in flat sections to reduce the height of the lifting device 1 and reduce the impact of wind; in obstacle sections, the sag can be reduced to increase the height, balancing efficiency and safety; for mountainous terrain with large elevation differences, the tension can be adjusted to allow the suspension cable 2 to adapt to different slope changes, avoiding loss of speed control of the lifting device 1 or collision of the material 12 with the slope due to excessively large slopes.

[0045] Furthermore, the lifting device 1 is fixedly connected to the suspension cable 2 via a sling gripper. The upper end of the lifting device 1 is provided with a lifting hole for connecting to the third cable 9, and the lower end of the lifting device 1 is provided with a hook for lifting the material 12.

[0046] In practice, the sling grip prevents the spreader 1 from detaching from the suspension cable 2, ensuring transportation safety, and facilitates disassembly and assembly as well as flexible adjustment at different positions of the suspension cable 2. A rotary bearing can also be installed between the spreader 1 and the sling grip, allowing the spreader 1 to rotate around the sling grip. When the third cable 9 pulls the spreader 1, the spreader 1 can automatically adjust its posture according to the direction of the tension of the third cable 9, ensuring that the direction of the tension of the third cable 9 is consistent with the central axis of the spreader 1, preventing the spreader 1 from shifting due to force and causing the material 12 to sway.

[0047] A buffer spring can be installed at the connection between the hook and the lifting device 1 to absorb vibrations during transportation; the center of gravity of the lifting hole, the hook, and the lifting device 1 can be designed to be located at the central axis of the lifting device 1 to minimize swaying caused by the shift of the center of gravity.

[0048] Example 2 Based on the same inventive concept, the present invention also provides a tethered balloon lifting suspension transport method, comprising the following steps: S1. Determine the locations of the first and second loading / unloading points based on the terrain of the mountainous area; S2. A first take-up and release mechanism 3 is set up at the first loading and unloading point, and a second take-up and release mechanism 4 is set up at the second loading and unloading point. The suspension cable 2 is deployed from the first loading and unloading point to the second loading and unloading point by a drone, so that one end of the suspension cable 2 passes through the first traction machine 301 of the first take-up and release mechanism 3 and is wound around the first drum 302, and the other end passes through the second traction machine 401 of the second take-up and release mechanism 4 and is wound around the second drum 402. S3. At the first loading and unloading point, the third launching mechanism 8 is installed at the lower end of the tethered balloon 5, and one end of the third cable 9 is connected to the third launching mechanism 8, and the other end is connected to the lifting hole at the upper end of the lifting device 1. The lifting device 1 is fixedly connected to the suspension cable 2 through the cable gripper. S4. A fourth deployment mechanism 10 is deployed at the first loading / unloading point, and a fifth deployment mechanism 11 is deployed at the second loading / unloading point. Anchoring of the fourth and fifth deployment mechanisms 10 and 11 is achieved by burying ground anchors. The tethered balloon 5 is connected to the fourth deployment mechanism 10 via the first cable 6 and to the fifth deployment mechanism 11 via the second cable 7. The fourth and fifth deployment mechanisms 10 and 11 are activated to coordinately deploy the first cable 6 and the second cable 7. Simultaneously, the third deployment mechanism 8 releases the third cable 9, causing the tethered balloon 5 to rise vertically from the first loading / unloading point until it reaches the preset working height. (e.g.) Figure 1 (As shown) S5. Activate the fifth deployment mechanism 11 to wind up the second cable 7, and simultaneously release the third cable 9 using the third deployment mechanism 8, causing the tethered balloon 5 to move to the corresponding position above the suspension cable 2; (e.g.) Figure 2 (As shown) S6. Based on transportation needs, select either the first or second loading / unloading point to attach the material 12 to the hook at the lower end of the spreader 1. Activate the third deployment / retraction mechanism 8 to wind up the third cable 9, utilizing the tethered balloon 5 to support the weight of the material. Through the coordinated deployment / retraction mechanism 3 and the second deployment / retraction mechanism 4, the suspension cable 2 is deployed / retracted, enabling the spreader 1 and the material 12 to move towards the target loading / unloading point. (e.g., Figure 3 , 4 (As shown) In practice, step S1 can use drone aerial photography and terrain surveying to determine the locations of the first and second loading / unloading points. The loading / unloading points are selected based on the following conditions: flat terrain, easy deployment of the loading / unloading mechanism and ground anchors, and no obstructions. For example, in a valley, the first loading / unloading point can be selected on a gentle terrace on one side of the valley, and the second loading / unloading point can be selected on a mountaintop platform on the other side.

[0049] In step S2, a drone can be used to carry one end of the suspension cable 2 from the first loading and unloading point, fly along a preset route to the second loading and unloading point, and complete the deployment of the suspension cable 2. After the suspension cable 2 is deployed, it can be initially tensioned by the first traction machine 301 and the second traction machine 401.

[0050] In step S3, the third deployment mechanism 8 can be fixed to the mounting base at the lower end of the tethered balloon 5 by bolts. One end of the third cable 9 is fixed to the drum of the third deployment mechanism 8, and the other end passes through the hoisting hole at the upper end of the lifting device 1 and is locked by the anti-detachment buckle. The rigging device can be fixed to the lifting device 1 and the suspension cable 2 by bolts.

[0051] In step S4, the ground anchors of the fourth and fifth deployment mechanisms 10 and 11 can be helical ground anchors, with a drilling depth of not less than 1.5 meters underground to ensure secure anchoring. When the tethered balloon 5 is launched, the fourth and fifth deployment mechanisms 10 and 11 can simultaneously deploy the cables, and the third deployment mechanism 8 can simultaneously release the third cable 9 to prevent the third cable 9 from pulling on the tethered balloon 5.

[0052] In step S5, the fifth take-up and release mechanism 11 takes up the second cable 7 while the third take-up and release mechanism 8 releases the third cable 9, which ensures that the tethered balloon 5 is stable in posture and does not tilt when it moves.

[0053] In step S6, when material 12 is mounted, the force with which the third winding mechanism 8 winds up the third cable 9 can be adjusted according to the weight of material 12.

[0054] Based on this invention, in steep slope areas, construction workers do not need to climb the slope; they can complete operations such as cable deployment and retrieval, and material loading at the loading and unloading point. The drone deployment of the suspension cable 2 eliminates the need to create construction access routes, and the spiral installation of the ground anchors avoids large-scale excavation, minimizing damage to mountain vegetation and soil.

[0055] Further, step S6 includes the following steps: S601. At the first loading and unloading point, the material 12 to be transported is attached to the hook at the lower end of the lifting device 1; S602. Start the third take-up and release mechanism 8 to wind up the third cable 9. The buoyancy of the tethered balloon 5, combined with the tension of the third cable 9, lifts the lifting device 1 and the material 12 upwards, and the tethered balloon 5 supports the weight of the material 12. S603. The first retraction mechanism 3 is activated to release the suspension cable 2, and the second retraction mechanism 4 simultaneously retracts the suspension cable 2, driving the lifting device 1 and the material 12 to move along the suspension cable 2 from the first loading / unloading point to the second loading / unloading point. During the process of the lifting device 1 moving from the first loading / unloading point along the suspension cable 2 to the corresponding position below the tethered balloon 5, the third retraction mechanism 8 simultaneously retracts the third cable 9. During the process of the lifting device 1 continuing to move from the corresponding position below the tethered balloon 5 along the suspension cable 2 to the second loading / unloading point, the third retraction mechanism 8 simultaneously releases the third cable 9.

[0056] In practical implementation, for scenarios where the suspension cable angle is relatively flat (such as...) Figure 5 As shown), the tethered balloon 5 can be positioned directly above the middle section of the suspension cable 2. The corresponding position below the tethered balloon 5 can be chosen directly below it, i.e., the vertical projection point of the third deployment / retraction mechanism 8 on the suspension cable 2. For scenarios where the suspension cable 2 has a steep angle (such as...), Figures 1-4 As shown), the tethered balloon 5 can be positioned above the suspension cable 2 on the side close to the second loading and unloading point. At this time, the corresponding position below the tethered balloon 5 can be selected at the vertical position of the third launching mechanism 8 to the suspension cable 2, ensuring that the tension direction of the third cable 9 matches the tangential direction of the suspension cable 2.

[0057] If material 12 is transported from the second loading / unloading point to the first loading / unloading point, the steps can be adjusted as follows: Load material 12 at the second loading / unloading point, activate the third retraction mechanism 8 to retract the third cable 9 to utilize the tethered balloon 5 to support the weight of material 12, activate the first retraction mechanism 3 to retract the suspension cable 2, and activate the second retraction mechanism 4 to release the suspension cable 2, driving the spreader 1 to move; when the spreader 1 moves from the second loading / unloading point to the corresponding position below the tethered balloon 5, the third retraction mechanism 8 retracts the third cable 9, and when it continues to move to the first loading / unloading point, the third retraction mechanism 8 releases the third cable 9.

[0058] Furthermore, a position sensor can be installed on the spreader 1 to provide real-time feedback on the distance between the spreader 1 and the corresponding position below the tethered balloon 5, providing accurate signals for the deployment and retrieval operation of the third deployment and retrieval mechanism 8; the deployment and retrieval speeds of the first deployment and retrieval mechanism 3 and the second deployment and retrieval mechanism 4 can be linked through the control system to ensure that the moving speed of the spreader 1 is stable.

[0059] In this invention, the timely adjustment of the third cable 9 at different positions of the lifting device 1 ensures that the weight of the material 12 is effectively supported by the tethered balloon 5. For example, at the first loading / unloading point, the third cable 9 is in a released state. After the material 12 is loaded, the third cable 9 is wound up to lift the lifting device 1, using the tethered balloon 5 to support the weight of the material 12. When moving below the tethered balloon 5, the length of the third cable 9 is at its shortest. When continuing to move towards the second loading / unloading point, the third cable 9 is released. The dynamic winding and unwinding of the third cable 9 can counteract the gravitational force generated by changes in terrain slope on the lifting device 1, preventing the lifting device 1 from accelerating or decelerating and ensuring the smooth transportation of the material 12.

[0060] Furthermore, step S6 also includes the following steps: S604. After unloading material 12 at the second loading and unloading point, the first winding and unloading mechanism 3 is activated to wind up the suspension cable 2, and the second winding and unloading mechanism 4 releases the suspension cable 2 simultaneously, driving the lifting device 1 to move along the suspension cable 2 from the second loading and unloading point to the first loading and unloading point. During the process of the lifting device 1 moving from the second loading and unloading point along the suspension cable 2 to the corresponding position below the tethered balloon 5, the third winding and unloading mechanism 8 simultaneously winds up the third cable 9. During the process of the lifting device 1 continuing to move along the suspension cable 2 from the corresponding position below the tethered balloon 5 to the first loading and unloading point, the third winding and unloading mechanism 8 simultaneously releases the third cable 9.

[0061] In practical implementation, the lifting device 1 in this invention can return independently without being loaded, without moving the tethered balloon 5, which greatly shortens the return time.

[0062] Furthermore, the third deployment and take-up mechanism 8 can be equipped with a PLC control system, a tension sensor, and an encoder. The tension sensor monitors the tension of the third cable 9 in real time, the encoder records the cable deployment and take-up lengths, and the PLC control system automatically controls the forward and reverse rotation of the motor of the third deployment and take-up mechanism 8 according to a preset program and the position signal of the lifting device 1, thereby realizing the winding and unwinding of the third cable 9. When the tethered balloon 5 moves (horizontally or vertically), its position signal can be transmitted to the PLC control system of the third deployment and take-up mechanism 8 via a GPS module. The system can then calculate the required change in the length of the third cable 9 and control the third deployment and take-up mechanism 8 to release or wind up synchronously. Based on this, the third deployment and take-up mechanism 8 can automatically adjust according to the position of the tethered balloon 5 and the cable tension, eliminating the need for real-time manual operation and reducing the risk of human error. It can still accurately complete the return operation at night or in environments with poor visibility.

[0063] Furthermore, after step S6, the following steps are also included: S7. After all materials 12 have been transported, the fifth launching mechanism 11 is activated to release the second cable 7, so that the tethered balloon 5 returns to above the first loading and unloading point; S8. Activate the fourth deployment mechanism 10 to wind up the first cable 6, and the third deployment mechanism 8 simultaneously winds up the third cable 9, so that the tethered balloon 5 lands on the ground and is anchored. S9. Disconnect the lifting device 1 from the suspension cable 2 and the third cable 9, and recover the lifting device 1, the recovered suspension cable 2, the tethered balloon 5, the first recovery and deployment mechanism 3, the second recovery and deployment mechanism 4, the first cable 6, the second cable 7, the third recovery and deployment mechanism 8 and the third cable 9, the fourth recovery and deployment mechanism 10 and the fifth recovery and deployment mechanism 11. Among them, the suspension cable 2 is recovered by drone.

[0064] In specific implementation, in step S7, the speed at which the fifth deployment mechanism 11 releases the second cable 7 can match the return speed of the tethered balloon 5, so as to avoid the second cable 7 from becoming loose and tangled; the fourth deployment mechanism 10 maintains the tension on the first cable 6, guiding the tethered balloon 5 back along the original path to above the first loading and unloading point.

[0065] In step S8, since the tethered balloon 5 is at the first loading and unloading point, the speed at which the fourth deployment mechanism 10 winds up the first cable 6 can be basically the same as the speed at which the third deployment mechanism 8 winds up the third cable 9, so that the tethered balloon 5 descends vertically and avoids tilting and collision; after landing on the ground, the tethered balloon 5 is anchored by ground anchors and tether locks to prevent it from moving due to wind.

[0066] In step S9, when dismantling the connection, the connection between the lifting device 1 and the third cable 9 can be dismantled first, and then the connection between the lifting device 1 and the suspension cable 2 can be dismantled. When the suspension cable 2 is being recovered, the drone can carry one end of the suspension cable 2 from the second loading and unloading point back to the first loading and unloading point, and simultaneously wind up the suspension cable 2 through the first traction machine 301 and the first drum 302 to ensure that the suspension cable 2 is recovered in an orderly manner and does not get tangled or dragged on the ground.

[0067] In this invention, the entire process of setting up, transporting, and recycling the transport device can be completed at the first and second loading and unloading points, eliminating the need for operations in the intermediate terrain. No construction operations are required in the intermediate barrier areas (valleys, forests, farmland, etc.), which can fully avoid vegetation damage and soil disturbance, while reducing the labor intensity and operational risks of construction personnel.

[0068] The above are merely embodiments of the present invention and are not intended to limit the present invention.
