Description

Technical Field

[0001] The utility model belongs to the technical field of mining equipment under complex seabed conditions, and in particular relates to a traveling device for a seabed mining vehicle. Background Art

[0002] As one of the core equipment for deep-sea resource extraction, the design of the crawler mechanism of deep-sea mining vehicles plays a crucial role in the entire mining operation. Traditional crawler-type crawler mechanisms, with their excellent load capacity and wide adaptability, have been used in a variety of geological conditions. However, in deep-sea soft soil environments, crawler mining vehicles face a series of technical bottlenecks in their driving performance.

[0003] Deep-sea rare soft soil, a special type of sediment, possesses unique physical properties such as high water content, low strength, high compressibility, and high sensitivity. These characteristics pose numerous challenges to the application of traditional tracked travel mechanisms in deep-sea environments. First, the high water content and low strength of the sediment cause the tracks to sink excessively in the soil, seriously impacting the stability and operating efficiency of the mining vehicle. Second, the high compressibility and low strength of the deep-sea rare soft soil make the tracks prone to slipping during travel, further reducing the traction and operating efficiency of the mining vehicle. This sinking and slipping not only affects the stability of mining operations but can also cause mechanical damage to the mining vehicle, increasing equipment maintenance and repair costs.

[0004] Furthermore, deep-sea mining operations can negatively impact the surrounding environment. In particular, the interaction between mining vehicles and seafloor sediments during operations can easily trigger plumes. A plume is a disturbance caused by mechanical operations that causes fine sediment to become suspended in the water. As the water flows, it can cause severe damage to the habitats of surrounding benthic organisms. The generation of plumes not only threatens ecosystem stability but also potentially impacts the sustainability of deep-sea resource extraction. Therefore, minimizing the generation of plumes and protecting the marine ecosystem while ensuring mining efficiency have become key issues that urgently need to be addressed in deep-sea mining technology.

[0005] At present, some studies have proposed setting up slides between the tracks to use the slides to bear the weight of the mining vehicle to reduce the sinking of the mining vehicle. However, in this way, the soil corresponding to the track part is still a soft soil layer, and the sinking and sliding of the track cannot be avoided. Especially when facing extremely soft soil layers, it is still difficult to effectively avoid the problems of sinking, sliding and ecological environment damage.

The following describes the walking device of the seabed mining vehicle through four specific embodiments:

[0043] To address the excessive sinking and slipping issues that existing tracked mining vehicles are prone to in deep-sea soft soil environments, while also minimizing the disturbance of benthic habitats caused by mining operations, this embodiment utilizes an innovative design combining tracks and slides, as well as their positional relationship, to enable the mining vehicle to operate stably in deep-sea soft soil environments, achieving the dual effects of improving operational efficiency and reducing ecological impact.

[0044] The following is a detailed description of the traveling device of the seabed mining vehicle with reference to the accompanying drawings:

[0045] like Figure 1-Figure 3 As shown, a traveling device for a submarine mining vehicle includes a mining vehicle frame 50, a crawler assembly, a slide assembly 20, a mounting bracket, and a shock absorber. The crawler assembly is mounted on the mining vehicle frame 50, and the slide assembly 20 is mounted on the mining vehicle frame 50 via the mounting bracket and the shock absorber. A control cabin 40 is also mounted on the mining vehicle frame 50.

[0046] The mining vehicle frame 50 is used to install the crawler device, the slide device 20 and the control cabin 40, etc., to form the basic frame structure of the mining vehicle.

[0047] Two sets of crawler devices are respectively installed on the mining vehicle frame 50.

[0048] The crawler device includes a crawler track 11, a drive wheel 12 connected to the mining vehicle frame 50, a load-bearing wheel 13 and a tensioning wheel 14. The drive wheel 12 is located at the rear of the crawler track 11, the tensioning wheel 14 is located at the front of the crawler track 11, and the load-bearing wheel 13 is located between the drive wheel 12 and the tensioning wheel 14.

[0049] The driving wheel 12 is connected to the crawler belt 11 , and the tensioning wheel 14 is connected to the crawler belt 11 .

[0050] The surface of the crawler 11 has V-shaped grousers to increase the contact area with the sediment, increase the shear force, and achieve effective movement on the sediment.

[0051] The two sets of slide devices 20 are respectively mounted on the mining vehicle frame 50. In the front-rear direction of the mining vehicle, the two sets of slide devices 20 are respectively located in front of the two sets of crawler devices.

[0052] The front end of the slide device 20 is tilted upward to facilitate the sliding of the slide device 20 and prevent the slide device 20 from damaging the seabed ecology.

[0053] The mounting brackets include a horizontal mounting bracket and a vertical mounting bracket 64 .

[0054] The transverse mounting bracket is arranged in the transverse direction, not specifically in the horizontal direction.

[0055] The vertical mounting bracket 64 is arranged in the vertical direction, but not specifically in the vertical direction.

[0056] The transverse mounting bracket is rotatably mounted on the mining vehicle frame 50 and includes an upper transverse mounting bracket 6121 and a lower transverse mounting bracket 6122. The upper transverse mounting bracket 6121 is rotatably connected to the top of the vertical mounting bracket 64, and the lower transverse mounting bracket 6122 is rotatably connected to the middle of the vertical mounting bracket 64. The slide device 20 is rotatably connected to the bottom of the vertical mounting bracket 64.

[0057] The connection between the transverse mounting bracket and the mining vehicle frame 50 and the vertical mounting bracket 64 allows the slide device 20 to swing up and down relative to the mining vehicle frame 50, allowing the slide device 20 to adaptively adjust its height up and down to follow the terrain. The rotational connection between the slide device 20 and the vertical mounting bracket 64 allows the slide device 20 to swing about the vertical mounting bracket, allowing the slide device 20 to adaptively swing up and down to follow the terrain. The mounting brackets enable the slide device 20 to adapt to different terrains.

[0058] The upper transverse mounting bracket 6121 is connected to the top of the vertical mounting bracket 64 through the universal shaft 60 , and the lower transverse mounting bracket 6122 is connected to the middle of the vertical mounting bracket 64 through the universal shaft 60 .

[0059] Therefore, the horizontal mounting bracket and the vertical mounting bracket 64 can swing in the left-right direction.

[0060] The buffer device can achieve stability during the adjustment process of the slide device 20.

[0061] The horizontal mounting bracket includes an intersecting first link 61 and a second link 62. The free ends of the first link 61 and the second link 62 are rotatably connected to the mining vehicle frame 50 via a rotating shaft. The intersection of the first link 61 and the second link 62 is rotatably connected to the vertical mounting bracket 64 via a universal joint 60.

[0062] The first connecting rod 61, the second connecting rod 62 of the transverse mounting bracket and the mining vehicle frame 50 form a stable triangular structure, thereby improving the stability of the transverse mounting bracket.

[0063] In the front-to-back direction of the mining vehicle, the first connecting rod 61 is located on the rear side of the second connecting rod 62, and the connection position between the vertical mounting bracket 64 and the slide device 20 is located on the front side of the second connecting rod 62, so as to improve the stability of the mounting bracket, make the mounting bracket bear reasonable force, and improve the service life of the mounting bracket.

[0064] The vertical mounting bracket 64 includes a vertical bracket 641, a first oblique bracket 642 and a second oblique bracket 643. The intersection of the first oblique bracket 642 and the vertical bracket 641 is connected to the upper horizontal mounting bracket 6121, the intersection of the second oblique bracket 643 and the vertical bracket 641 is connected to the lower horizontal mounting bracket 6122, and the intersection of the first oblique bracket 642 and the second oblique bracket 643 is rotatably connected to the skateboard device 20.

[0065] The vertical mounting bracket 64 forms a stable structure, which can greatly improve the stability of the vertical mounting bracket 64.

[0066] A connecting rod 644 is provided between the intersection of the vertical bracket 641 and the second oblique bracket 643 and the first oblique bracket 642 , and the lower horizontal mounting bracket 6122 is connected to a position of the connecting rod 644 close to the vertical bracket 641 .

[0067] Adding the connecting rod 644 increases the stability of the vertical support 641 .

[0068] The first oblique bracket 642 includes a first bracket portion and a second bracket portion, and the first bracket portion and the second bracket portion are arranged at a certain angle.

[0069] The shock absorbing device is connected to the mounting bracket and the mining vehicle frame 50 to provide a shock absorbing effect on the slide device 20 during the operation of the mining vehicle.

[0070] The shock absorbing device includes a first shock absorbing device, which includes a first telescopic rod 311 and a first shock absorbing spring 312 mounted on the first telescopic rod 311. One end of the first telescopic rod 311 is rotatably connected to the mining vehicle frame, and the other end of the first telescopic rod 311 is rotatably connected to the mounting bracket.

[0071] Specifically, one end of the first telescopic rod 311 is connected to the mining vehicle frame near the upper horizontal mounting bracket 6121, and the other end of the first telescopic rod 311 is connected to the lower horizontal mounting bracket 6122 near the vertical mounting bracket 64, or the other end of the first telescopic rod 311 is connected to the middle of the vertical mounting bracket 64.

[0072] When the mining vehicle moves forward on an undulating slope, the high terrain on one side causes the slide plate to rise, compressing the first shock-absorbing device on that side, thereby playing a shock-absorbing role and preventing the mining vehicle from tilting too much.

[0073] The shock absorbing device includes a second shock absorbing device, which includes a shock absorbing link 323, a second telescopic rod 321 and a second shock absorbing spring 322 located on the second telescopic rod 321. One end of the shock absorbing link 323 is rotatably connected to the vertical mounting bracket, and the other end of the shock absorbing link 323 is rotatably connected to one end of the second telescopic rod 321. The other end of the second telescopic rod 321 is connected to the mining vehicle frame.

[0074] The other end of the second telescopic rod 321 is connected to the front end of the mining vehicle frame 50 .

[0075] The front end of the mining vehicle frame 50 has a through hole, and the two sets of second telescopic rods 321 can pass through the through hole for connection.

[0076] The middle part of the vertical mounting bracket 64 is rotatably connected to the damping connecting rod 323 via a rotating shaft. The vertical mounting bracket 64 and the damping connecting rod 323 have a certain amount of activity margin so that the skateboard device 20 can swing slightly left and right.

[0077] When the mining vehicle moves forward on an undulating slope, the terrain on one side causes the slide plate to swing to the opposite side, compressing the second shock absorbing device on that side. The second shock absorbing spring 322 on that side plays a shock absorbing role and prevents the mining vehicle from tilting too much.

[0078] The control cabin 40 includes a control system, which controls the operating state of the crawler drive motor.

[0079] The control cabin 40 is also provided with a power supply, a communication device, a memory, and the like.

[0080] When the mining vehicle is in operation, the control cabin 40 provides power and motion control to ensure the movement of the mining vehicle. The crawler track 11 is connected to the driving wheel 12 and the tensioning wheel 14 on both sides. The crawler track 11 rotates under the drive of the driving wheel 12, and the tensioning wheel 14 also rotates. Under the action of the tensioning wheel 14, the crawler track 11 can remain in a tensioned state and thus move on the seabed. The slide device 20 located in the front is located above the sediment and can pre-compact the sediment. The slide device can be adaptively adjusted according to the terrain, and the planar structure of the slide and the upward-curved structure of the front end can avoid the generation of turbulence. Under the push of the crawler track 11, the slide device 20 slides on the sediment, thereby reducing the disturbance of the sediment and excessive subsidence.

[0081] The traveling device of the seabed mining vehicle can operate stably in complex deep-sea geological environments, especially in extremely soft soil layers. The coordination of the skateboard and the track can ensure the stable driving and operation of the mining vehicle. By reducing the negative impact of the mining vehicle on the environment during operation and improving work efficiency through design optimization, it not only ensures the smooth progress of mining operations, but also reduces the maintenance cost of equipment and improves economic benefits.

[0082] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
