Description

Technical Field

[0001] This application relates to the field of underwater mining vehicle structure technology, and more specifically, to a replaceable mining rake mechanism and an underwater mining vehicle. Background Technology

[0002] The ocean floor contains abundant mineral resources. With the advancement of science and technology and the gradual depletion of easily mined resources on land, seabed mining is attracting increasing attention. Current seabed mining operations typically utilize mining trucks for excavation.

[0003] Existing underwater mining vehicles typically have mining rake mechanisms on both sides of the front end of the vehicle body. During mining, these rake mechanisms rotate to dig up the ore from the seaweed, facilitating mining at the front end of the vehicle. However, these rake mechanisms wear down due to prolonged contact with the ore. Since the rake mechanisms are installed before the vehicle is launched, when the rake mechanisms wear out, the entire mining vehicle must be lifted from the seabed before the rake mechanisms can be manually disassembled and replaced. This process of lifting the mining vehicle to the surface is time-consuming and labor-intensive, making the replacement of worn rake mechanisms inconvenient, increasing maintenance time, reducing operational efficiency, and hindering efficient and stable mining operations.

[0004] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

[0005] The purpose of this application is to provide a replaceable mining rake mechanism and an underwater mining vehicle, which solves the problems in the prior art where the mining rake mechanism is not easy to replace after wear, which increases maintenance time and reduces the operating rate.

[0018] The first clamp and the second clamp form a clamping space for clamping the bearing housing. The second gear meshes with the first gear so that the rotating first clamp drives the second clamp to rotate, thereby opening or closing the clamping space.

[0019] Optionally, the outer surface of the bearing housing is provided with multiple clamping and limiting surfaces, and the clamping space has multiple clamping inner walls that match the clamping and limiting surfaces.

[0034] The hinge rod is hinged to the mounting bracket. Both ends of the hinge rod are provided with a stop and a pressing rod, respectively. The pressing rod is connected to the locking assembly and is driven by the locking assembly to move the stop away from the stop block.

[0035] The resilient return element connects the mounting bracket and the hinge rod, and when the locking assembly releases the mining rake, it pulls the hinge rod to cause the stop block to block the stop block.

A locking assembly is used to clamp or release the mining rake. When the mining rake wears down during kelp mining, it is released via the locking assembly, and an underwater robot removes the worn mining rake from the docking part for replacement. The new mining rake is then installed onto the docking part by the underwater robot and clamped by the locking assembly. This enables timely underwater replacement of the worn mining rake mechanism, greatly optimizing the replacement method and making seabed replacement of the mining rake mechanism more convenient.

[0051] Example 1

[0052] like Figure 1 As shown, this embodiment proposes a replaceable mining rake mechanism for connection to the mining vehicle body 10, which is the main part of the underwater mining vehicle and is mainly used for underwater mobile mining. This mining rake mechanism is replaceably located on the left and right sides of the front end of the mining vehicle body 10. Figure 1 , Figure 2 , Figure 3 As shown, the mining rake mechanism mainly includes: a mounting frame 100, a drive unit 200, a mining rake 300, and a locking assembly 400. The mounting frame 100 is used to connect to the mining vehicle body 10, mainly serving as a fixed part to provide mounting positions for other components, and it can be part of the front end structure of the mining vehicle body 10. The drive unit 200 is mounted on the mounting frame 100, and a docking part 210 is provided on the main shaft of the drive unit 200. The drive unit 200 can be a hydraulic motor, which is fixedly connected to the mining vehicle body 10 through the mounting frame 100. When replacing the mining rake mechanism, it does not need to be replaced, so the hydraulic pipeline will not be changed, and there will be no problem of pipeline disassembly and assembly during the replacement process, thus making the disassembly and assembly process simpler and easier to implement. The mining rake 300 is detachably connected to the main shaft of the drive unit 200 via the docking part 210 and rotates under the drive of the drive unit 200. The mining rake 300 is the main replacement structure. After being connected to the drive unit 200 via the docking part 210, it rotates under the drive of the drive unit 200, thereby realizing the mining function. The locking assembly 400 is mounted on the mounting frame 100 and clamps or releases the mining rake 300 connected to the drive unit 200. When the mining rake 300 needs to be replaced, the locking assembly 400 is released, allowing the mining rake 300 to be removed for easy replacement. After the mining rake 300 is replaced, the locking assembly 400 is locked, allowing the mining rake 300 to be stably set up and rotate stably under the drive of the drive unit 200.

[0053] like Figure 1 , Figure 2 , Figure 3 As shown, the replaceable mining rake mechanism of this embodiment uses a mounting bracket 100 on the mining vehicle body 10 to mount the drive unit 200, allowing the mining rake 300 to be detachably connected to the drive unit 200 via a docking part 210. A locking assembly 400 clamps or releases the mining rake 300. When the mining rake 300 wears down during kelp mining, it is released via the locking assembly 400, and an underwater robot removes the worn mining rake 300 from the docking part 210 for replacement. The new mining rake 300 is then installed onto the docking part 210 by the underwater robot and clamped by the locking assembly 400. This allows for timely underwater replacement of the worn mining rake mechanism, greatly optimizing the replacement method and making seabed replacement of the mining rake mechanism more convenient.

[0054] like Figure 2 , Figure 3 , Figure 4As shown, further, one axial end of the mining rake 300 in this embodiment is a mounting end 310. The mining rake 300 is detachably connected to the docking part 210 through the mounting end 310. A bearing seat 320 is provided on one side of the mounting end 310, and rake teeth 330 are provided on the side of the bearing seat 320 opposite to the mounting end 310. The bearing seat 320 is used to dock with the locking assembly 400 so that the mining rake 300 can rotate. Therefore, a bearing 321 is provided inside the bearing seat 320, and the mining rake 300 is rotatably connected to the bearing seat 320 through the bearing 321.

[0055] like Figure 2 , Figure 3 , Figure 4 As shown, the locking assembly 400 of this embodiment specifically includes a drive unit 410, a connecting rod unit 420, and a clamping unit 430. The drive unit 410 is mounted on the mounting bracket 100 and can specifically be a hydraulic cylinder, whose piston rod extends and retracts hydraulically. The hydraulic cylinder is fixedly mounted on the mounting bracket 100 in the vertical direction. The connecting rod unit 420 is connected to the drive unit 410 and is moved by the drive unit 410; when the piston rod of the hydraulic cylinder extends or retracts, it provides power to the connecting rod unit 420. The clamping unit 430 is connected to the connecting rod unit 420 and clamps or releases the bearing seat 320 by the drive of the connecting rod unit 420. The moving connecting rod unit 420 drives the clamping unit 430 to move. When the mining rake 300 needs to be replaced, the drive unit 410 drives the connecting rod 420 to drive the clamping part 430, forming a loose state; after the mining rake 300 is replaced, the drive unit 410 drives the connecting rod 420 to drive the clamping part 430, forming a locked state, so that the bearing seat 320 is stably fixed, and the mining rake 300 can rotate stably.

[0056] like Figure 3 , Figure 4 , Figure 5As shown, the clamping part 430 in this embodiment further includes a first clamping seat 431 and a second clamping seat 435. The first clamping seat 431 is rotatably connected to the mounting frame 100 via a first hinge position 432 and is hinged to the connecting rod part 420. A first gear part 433 is provided on the first clamping seat 431, and the first gear part 433 rotates around the first hinge position 432. The second clamping seat 435 is rotatably connected to the mounting frame 100 via a second hinge position 436, and a second gear part 437 is provided on the second clamping seat 435. The first clamping seat 431 and the second clamping seat 435 form a clamping space 500, which is used to clamp the bearing seat 320. The second gear part 437 meshes with the first gear part 433, so that the rotating first clamping seat 431 drives the second clamping seat 435 to rotate, thereby opening or closing the clamping space 500. A hinge platform 434 is provided on the upper surface of the first clamping seat. The connecting rod 420 is hinged to the hinge platform 434. The rear sides of the first clamping seat and the second clamping seat are respectively hinged, while the front side forms an opening 510. Therefore, the front side of the clamping space 500 forms an opening 510 for the bearing seat 320 to enter and exit during installation. For the convenience of structural description, the direction from front to back is the direction of entry of the bearing seat 320, and the direction from back to front is the direction of removal of the bearing seat 320. The first clamp 431 and the second clamp 435 rotate due to the push of the connecting rod 420. Under the action of the first gear 433 and the second gear 437, the first clamp 431 and the second clamp 435 rotate in opposite directions. This allows the opening 510 of the clamping space 500 to open or close. When the clamping space 500 is open, the bearing seat 320 can smoothly enter the clamping space 500 from front to back. Then, the first clamp 431 and the second clamp 435 are tightened, fixing the bearing seat 320 in the clamping space 500. This structure allows the first clamp 431 and the second clamp 435 to rotate synchronously in opposite directions, making it easy to center the bearing seat 320 during clamping and ensuring the installation accuracy of the bearing seat 320.

[0057] like Figure 4 , Figure 5 , Figure 6As shown, further, the outer surface of the bearing seat 320 in this embodiment is provided with a plurality of clamping and limiting surfaces 322, and the clamping space 500 has a plurality of clamping inner walls 501 that match the clamping and limiting surfaces 322. The bearing seat 320 is limited and fixed in the clamping space 500 by the cooperation of the clamping and limiting surfaces 322 and the clamping inner walls 501. In the specific structure, the plurality of clamping and limiting surfaces 322 of the clamping space 500 can form a hexagonal clamping space 500. The inner wall on the opening 510 side is separated by the opening 510. Then, the first clamp 431 and the second clamp 435 form inclined clamping surfaces on the inner walls on the opening 510 side. By using polygonal clamping inner walls 501, the bearing seat 320 can be better limited in the clamping space 500. When the bearing seat 320 is clamped, it will not loosen, thereby ensuring the connection stability of the bearing seat 320.

[0058] like Figure 4 , Figure 5 , Figure 6 As shown, in the specific structure, the first clamping seat 431 is provided with an upper stop block 520 at the opening 510 of the clamping space 500, and the second clamping seat 435 is provided with a lower stop block 530 at the opening 510 of the clamping space 500. The inner sides of the upper stop block 520 and the lower stop block 530 are both inclined clamping surfaces. The upper stop block 520 and the lower stop block 530 cooperate to open or close the opening 510. In the closed state, the bearing seat 320 located in the clamping space 500 can be clamped by the cooperation of the inner sides of the upper stop block 520 and the lower stop block 530.

[0059] like Figure 2 , Figure 3 , Figure 5 , Figure 6As shown, further, the mounting bracket 100 of this embodiment is provided with a mounting guide bracket 110, which is located on one side of the clamping part 430. In a specific structure, the mounting guide bracket 110 can be located on the left or right side of the clamping part 430; in this embodiment, it is located on the side closer to the driving force member 200. The mounting guide bracket 110 is provided with a push-in guide surface 111 and a guide support surface 112. The guide support surface 112 is located on the side of the push-in guide surface 111 facing the entry direction, and therefore the guide support surface 112 is located on the rear side of the push-in guide surface 111. The push-in guide surface 111 is inclined and is used to guide the bearing seat 320 to the guide support surface 112. In a specific structure, the push-in guide surface 111 gradually rises from front to back, thus having a large angle to facilitate the bearing seat 320 to abut against it and move, so that the bearing seat 320 can smoothly enter the guide support surface 112. The guide support surface 112 supports the bearing housing 320. The bearing housing 320 has a relatively large thickness (thickness in the left-right direction). Therefore, a portion of one side of the bearing housing 320 in the left-right direction is supported by the guide support surface 112, while a portion of the other side enters the clamping space 500. Furthermore, when the bearing housing 320 is pushed onto the guide support surface 112, the central axis of the mining rake 300 is aligned with the rotation center of the rotation axis of the driving force component 200. This aligns the mining rake 300 and the docking part 210 in height, making the installation process of the mining rake 300 and the docking part 210 more convenient.

[0060] In this embodiment, when the bearing seat 320 is in the open state, the lower stop block 530 is lower than the push-in guide surface 111. This ensures that the lower stop block 530 will not interfere with the bearing seat 320 during its movement, making the movement of the bearing seat 320 smoother.

[0061] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the linkage portion 420 in this embodiment further includes a first drive plate 421 and a drive linkage 423. The first drive plate 421 is connected to the drive portion 410, and a U-shaped groove 422 is formed on the first drive plate 421. One end of the drive linkage 423 is movably connected in the U-shaped groove 422, and the other end is hinged to the clamping portion 430. The drive function is realized by using a linkage structure, which is simple in structure.

[0062] like Figure 2 , Figure 4 , Figure 5 , Figure 7As shown, the docking part 210 in this embodiment further includes a connector seat 211 and a C-shaped socket 212. The connector seat 211 is connected to the main shaft of the drive member 200, and the C-shaped socket 212 is formed on the connector seat 211. One end of the mining rake 300 is provided with a positioning shaft surface 311, which is located at the mounting end 310. The mining rake 300 is inserted into and limited within the C-shaped socket 212 through the positioning shaft surface 311. In the specific structure, a positioning plane 213 is also provided on the C-shaped socket 212, so that the mounting end 310 of the mining rake 300 can be limited after being inserted into the C-shaped socket 212. The C-shaped socket 212 is formed into a flared opening 214 to facilitate the insertion of the mounting end 310 of the mining rake 300. It should be noted that the positioning axis surface 311 on the mounting end 310 of the mining rake 300 is also the positioning reference surface for the underwater robot to hold the mining rake 300. When the underwater robot holds the mining rake 300, it always uses the positioning axis surface 311 as the reference to keep the mining rake 300 aligned with the C-shaped socket 212, so that the mounting end 310 of the mining rake 300 can be accurately inserted into the connector seat 211 to achieve connection.

[0063] like Figure 4 , Figure 5 , Figure 7 As shown, in this embodiment, a stop block 220 is further provided on the outer wall of the connector seat 211. The mining rake mechanism also includes a movable limiting member 600, which blocks or allows the stop block 220 to move. By cooperating with the stop block 220 and the movable limiting member 600, the position of the docking part 210 can be fixed when the mining rake 300 needs to be disassembled. In this way, the C-shaped insertion port 212 on the docking seat can face forward in a predetermined position, so that the replacement position of the mining rake 300 is uniform and consistent with the entry and removal directions of the bearing seat 320.

[0064] like Figure 2 , Figure 5 , Figure 7As shown, the movable limiting member 600 in this embodiment specifically includes a hinge rod 610 and an elastic return member 620. The hinge rod 610 is hinged to the mounting frame 100. A stop block 611 and a pressing rod 612 are respectively provided at both ends of the hinge rod 610. The pressing rod 612 is connected to the locking assembly 400 and is driven by the locking assembly 400 to move the stop block 611 away from the stop block 220. The elastic return member 620 connects the mounting frame 100 and the hinge rod 610, and when the locking assembly 400 releases the mining rake 300, it pulls the hinge rod 610 to make the stop block 611 block the stop block 220. In the specific structure, a pressing plate 411 is provided on the piston shaft of the drive unit 410. The pressing plate 411 extends in the left and right direction and is located above the pressing rod 612. The pressing plate 411 is driven by the drive unit 410 to press the pressing rod 612, thereby allowing the stop block 611 at the other end to be lifted under the leverage action of the hinge rod 610. Therefore, by moving the pressing plate 411 downward, the stop block 611 is driven upward away from the stop block 220 by the hinge rod 610. When the pressing plate 411 moves downward, the connecting rod part 420 is driven by the drive unit 410 to press the clamping part 430 downward, thereby clamping the bearing seat 320. In this way, by driving the drive unit 410 downward, the connection of the mining rake 300 is realized while the obstruction of the stop block 220 is released. The upward movement of the pressing plate 411 causes the hinge rod 610 to move under the pull of the elastic return member 620, thereby blocking the stop block 611 in front of the stop block 220. When the pressing plate 411 moves upward, the connecting rod part 420 pulls the clamping part 430 upward under the drive of the drive part 410, thereby releasing the bearing seat 320. In this way, the upward drive of the drive part 410 realizes the release of the mining rake 300 while blocking the stop block 220, making the disassembly and assembly of the mining rake 300 more convenient.

[0065] In addition, an arc-shaped surface 412 is provided at one end of the pressing plate 411 facing the hinge rod 610. During the downward movement of the pressing plate 411, the arc-shaped surface 412 presses the pressing rod 612, allowing the pressing rod 612 to rotate smoothly.

[0066] Example 2

[0067] like Figure 1 As shown, this embodiment proposes an underwater mining vehicle, which includes a mining vehicle body 10 and at least two replaceable mining rake mechanisms as described above. The at least two mining rake mechanisms are respectively arranged on the left and right sides of the front end of the mining vehicle body 10.

[0068] In summary, this application provides a replaceable mining rake mechanism and an underwater mining vehicle. When the mining rake wears down during kelp mining, the locking assembly loosens the rake, and an underwater robot removes the worn rake from the docking part for replacement. The underwater robot then installs the new rake onto the docking part and clamps it in place using the locking assembly. This enables timely underwater replacement of the worn mining rake mechanism, significantly optimizing the replacement method and making seabed replacement of the mining rake mechanism more convenient.

[0069] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
