DETAILED DESCRIPTION

[0054] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0055] Embodiment 1:

[0056] like Figure 1-Figure 3 As shown, the standardized mining transport box provided in the first embodiment of the present invention includes a corner column assembly 2, the corner column assembly 2 includes a corner piece, a fixed hook 29 is provided in the corner piece, and the fixed hook 29 is configured to be locked by the first locking mechanism 19 of the load-bearing platform.

[0057] By setting a fixed hook 29 in the corner piece of the corner column assembly 2 to be locked by the first locking mechanism 19 of the load-bearing platform, the standardized mining transport box can be separated from the load-bearing platform. The standardized mining transport box adopts a modular design, and the standardized mining transport box can be used separately from the load-bearing platform to realize the detachable modular characteristics, which is conducive to improving the use efficiency of the transportation equipment.

[0058] like Figure 5 As shown, the corner column assembly 2 further includes a corner column 9. Since the standardized mining transport box is generally a rectangular parallelepiped, the corner column assembly 2 is arranged at the four corners of the standardized mining transport box. The top of the corner column 9 is connected to an upper corner piece 8, and the bottom of the corner column 9 is connected to a lower corner piece 10, which can be connected to the load-bearing platform. In order to facilitate the connection of the standardized mining transport box with other types of load-bearing platforms other than the second embodiment, the side wall of the corner piece can be provided with an opening.

[0059] like Figure 4 and Figure 6 As shown, optionally, the standardized mining transport box also includes a box assembly 1 and a box crossbeam assembly 4, the box assembly 1 has a box bottom plate 7, a first box side plate 5 and a second box side plate 6, the bottoms of the first box side plate 5 and the second box side plate 6 are fixedly connected to the box bottom plate 7, the length of the first box side plate 5 is greater than the length of the second box side plate 6, and the first box side plate 5 and the second box side plate 6 are equal in height; the corner column assembly 2 includes a corner column 9, and the side edges of the first box side plate 5 and the second box side plate 6 are fixedly connected to the corner column 9; the box crossbeam assembly 4 includes a first box crossbeam 15 and a second box crossbeam 14, the length of the first box crossbeam 15 is greater than the second box crossbeam 14, and the ends of the first box crossbeam 15 and the second box crossbeam 14 are fixedly connected to the opposite sides of each corner piece.

[0060] By providing the corner column assembly 2 to connect the first box side panel 5 and the second box side panel 6, the rigidity of the box assembly 1 can be significantly improved to avoid damage when the material is contained. The box cross beam assembly 4 is provided on the lower surface of the box bottom panel 7 to improve the strength of the box bottom panel 7.

[0061] In this embodiment, a notch is provided at the top of the first box crossbeam 15 for the fork arm of the forklift to be inserted. In this embodiment, there are two second box side panels 6, and one first box side panel 5. In addition, notches with the same outer dimensions as the corner columns 9 are cut out at the four corners of the box bottom panel 7, so that the box bottom panel 7 will not interfere with the corner columns 9. In addition, reinforcing ribs are provided on the outer sides of the first box side panel 5 and the second box side panel 6 to improve the rigidity of the first box side panel 5 and the second box side panel 6. In addition, an upper crossbeam 16 is also provided at the top of the box assembly 1, and the upper crossbeam 16 is connected to the two upper corner pieces 8 to improve the rigidity of the top of the side of the box assembly 1 where the first box side panel 5 is not provided.

[0062] like Figure 7-Figure 8 As shown, optionally, the standardized mining transport box also includes a double-door assembly 3, the double-door assembly 3 includes a box door 12 and a lock 13, the box door 12 is connected to the corner column assembly 2 by a hinge 11, and the length of the box door 12 is half of the first box side panel 5; the lock 13 is installed on the box door 12, the lock 13 includes a lifting lock body 133, the lifting lock body 133 is pivotally connected to the lock rocker 132, and the lock 13 and the box door 12 are relatively vertically movable; a lock buckle 134 is also installed on the first box cross beam 15, and the lifting lock body 133 can be inserted into the lock buckle 134.

[0063] By using the hinge 11 to pivotally connect the box door 12 to the corner column assembly 2, when it is necessary to transport materials into the standardized mining transport box in the horizontal direction, the lock rocker 132 can be used to drive the lifting lock body 133 to rise, so that the lock body is pulled out of the lock buckle 134, thereby unlocking the lock 13, so that the box door 12 can be opened, and materials can be transported into the standardized mining transport box in the horizontal direction.

[0064] Among them, the corner posts 9 located on both sides of the front surface of the standardized mining transport box among the four corner posts 9 may have L-shaped cross sections in order to leave space for the hinges 11, while the cross sections of the remaining corner posts 9 may be rectangular. A base of the hinge 11 may be fixedly connected to the corner post 9 by means such as welding, and the swinging part of the hinge 11 may be fixedly connected to the box door 12, and two hinges 11 are provided on the side of each box door 12. A reinforcing rib structure is also provided on the outside of the box door 12 to improve rigidity, wherein the position where the hinge 11 is connected should avoid the reinforcing rib structure.

[0065] The lock 13 includes a lock base 131, in which a groove is provided which runs through the lock base 131, and the height of the groove is greater than the height of the lock swing rod 132. The lock swing rod 132 can not only move left and right relative to the lock base 131, but also swing and move up and down in the lock base 131. The lifting lock body 133 can be specifically a lock rod, the bottom of which penetrates into the lock buckle 134, and the upper and lower ends of the lock rod are fixed to the door 12 through the sliding base. That is, taking the left door 12 as an example, when the left end of the lock swing rod 132 is pressed down, the lock swing rod 132 not only rotates relative to the lock base 131, but also the right end of the lock swing rod 132 rises. When the lifting lock body 133 is lifted or lowered, the lifting lock body 133 can move up and down relative to the sliding base. The lock swing rod 132 also moves to the right to prevent interference.

[0066] Embodiment 2:

[0067] like Figure 9-12 As shown, the load-bearing platform provided in the second embodiment is used to carry the above-mentioned standardized mining transport box. The load-bearing platform includes a frame assembly 17 and a first locking mechanism 19. The first locking mechanism 19 is installed at the corner of the frame assembly 17 and is arranged corresponding to the corner piece; the first locking mechanism 19 includes a movable coupler 31 and a reset assembly. The movable coupler 31 can be held in position by the reset assembly.

[0068] By setting a reset component to keep the movable hook 31 in position, the movable hook 31 can be opened by using the reset component to facilitate the insertion of the fixed hook 29 of the corner piece, and then the movable hook 31 can be reset by using the reset component to keep the movable hook 31 in the locked position, ensuring that the movable hook 31 and the fixed hook 29 are securely locked.

[0069] like Figure 12-Figure 18As shown, optionally, the first locking mechanism 19 includes a locking bracket 33, and the movable hook 31 is pivoted to the locking bracket 33; the reset assembly includes a reset lever 35, a lock core counterweight 38, a first connecting rod 39, a second connecting rod 40, a rotating slide 41 and a swing lock core 42, the lock core counterweight 38 is slidably connected to the locking bracket 33 in the vertical direction, the lock core counterweight 38 is pivoted to the first connecting rod 39, the first connecting rod 39 is pivoted to the second connecting rod 40, the second connecting rod 40 is pivoted to the swing lock core 42, the second connecting rod 40 is also slidably connected to the rotating slide 41, the rotating slide 41 is pivoted to the locking bracket 33, and the swing lock core 42 has a horizontal protrusion. 421; the reset lever 35 is pivoted to the locking bracket 33, the horizontal protrusion 421 extends into the upper part of the first end of the reset lever 35, and the second end of the reset lever 35 extends into the toggle groove 322 of the movable hook 31; the pivot axes between the first connecting rod 39 and the second connecting rod 40, between the lock core counterweight 38 and the first connecting rod 39, between the second connecting rod 40 and the swing lock core 42, and between the rotating slide groove 41 and the locking bracket 33 are parallel; the rotation axis of the movable hook 31 is parallel to the rotation axis of the reset lever 35; the pivot axes between the movable hook 31 and the locking bracket 33, and between the rotating slide groove 41 and the locking bracket 33 are vertical;

[0070] When the lock core counterweight 38 descends, the horizontal protrusion 421 can lock the movable coupler 31 ; when the lock core counterweight 38 ascends, the horizontal protrusion 421 can drive the movable coupler 31 to release the connection with the fixed coupler 29 .

[0071] With such arrangement, when the lock core counterweight 38 rises, the swing lock core 42 can be rotated by using the first connecting rod 39, the second connecting rod 40 and the rotating slide groove 41, thereby driving the horizontal protrusion 421 of the swing lock core 42 to press down the reset lever 35, and then the reset lever 35 presses down one end of the toggle groove 322, driving the movable hook 31 to open. When the lock core counterweight 38 moves downward under the influence of its own weight, the swing lock core 42 can be driven by the first connecting rod 39 and the second connecting rod 40 to swing in the opposite direction, so as to achieve the locking of the movable hook 31 with the fixed hook 29. Moreover, since the pivot axis of the movable hook 31 and the locking bracket 33 is perpendicular to the pivot axis of the second connecting rod 40 and the swing lock core 42, the continued swing of the movable hook 31 will hit the swing lock core 42, and the direction is parallel to the rotation axis of the swing lock core 42, so the swing lock core 42 can be used to prevent the movable hook 31 from continuing to swing, so as to ensure the firm connection between the movable hook 31 and the fixed hook 29.

[0072] In this embodiment, the movable hook 31 is pivotally connected to the upper portion of the locking bracket 33 via the hook shaft 32 .

[0073] Among them, Fig.15 and Fig.16As shown in the figure, when the lock core counterweight 38 is in a lower position, the end of the first link 39 pivotally connected to the lock core counterweight 38, that is, the lower end of the first link 39, is lowered. The second link 40 is slidably connected to the rotating slot 41. Driven by the upper end of the first link 39, the angle between the second link 40 and the horizontal plane increases. Since the rotating slot 41 is pivotally connected to the locking bracket 33, the second link 40 is Fig.13 The upper end shown moves to the left, and the horizontal protrusion 421 of the swing lock cylinder 42 moves to the side of the movable coupler 31 facing the observer, blocking the continued swinging of the movable rod coupler to achieve a reliable connection between the movable coupler 31 and the fixed coupler 29.

[0074] like Figure 12-14 and Fig.17 As shown, when the lock core counterweight 38 moves upward, it pushes the lower end of the first connecting rod 39 at its top. Since the first connecting rod 39 is pivotally connected to the second connecting rod 40, the second connecting rod 40 is slidably connected to the rotating slot 41, and the rotating slot 41 is pivotally connected to the locking bracket 33. Therefore, the second connecting rod 40 is pushed upward by the first connecting rod 39, and the second connecting rod 40 moves upward relative to the rotating slot 41. At the same time, the angle between the second connecting rod 40 and the horizontal plane becomes smaller, and the pivot point position of the second connecting rod 40 and the swing lock core 42 moves to the right. At the same time, since a limiting portion 43 is provided on the top of the swing bracket, the top of the swing lock core 42 abuts against the limiting portion 43, so that the swing lock core 42 starts to swing. When the lock core counterweight 38 continues to move upward, the pivot position of the swing lock core 42 and the second connecting rod 40 moves to the upper right in the figure, so that the swing lock core 42 is in the state of being locked. Fig.15 The horizontal protrusion 421 presses down the reset lever 35 , and the reset lever 35 moves the bottom end of the slot 322 , so that the movable coupler 31 opens outward to release the fixed coupler 29 .

[0075] In the first locking mechanism 19, the lock core counterweight 38 exerts a leftward constraint force on the swing lock core 42 through the first connecting rod 39 and the second connecting rod 40 under the action of gravity, and keeps the horizontal protrusion 421 of the swing lock core 42 and the bottom surface of the movable hook 31 in the locked state, restricting the rotation movement of the movable hook 31 and realizing the self-locking of the movable hook 31. The transmission chain is composed of the lock core counterweight 38, the first connecting rod 39, the second connecting rod 40, the rotating slide 41, and the swing lock core 42. The movement of each component is on the vertical plane. The simplified motion model is as follows: Fig.16 The first locking mechanism is shown in the schematic diagram of the mechanism, calculated according to the plane freedom formula:

[0076] F=3n-2P L -P H =3×5-2×7-1×0=1 (1)

[0077] F is the number of plane degrees of freedom; n is the number of movable rods; P Lis the number of low pairs; P H It is the number of high pairs.

[0078] It can be obtained that the number of degrees of freedom of the internal transmission chain of the first locking mechanism 19 is 1. Based on the closed chain kinematics, further calculation and derivation can be obtained that the up and down movement of the lock core counterweight 38 corresponds to the left and right translation movement of the swing lock core 42:

[0079] L1cosθ1+acosθ2=x (2)

[0080] L1sinθ1+asinθ2=h (3)

[0081] (L2-a)sinθ2=Δh (4)

[0082] p=x+(L2-a)cosθ2 (5)

[0083] L1 is the length of the first connecting rod 39, the actual size is 22mm; L2 is the length of the second connecting rod 40, the actual size is 42mm; θ1 is the angle between the first connecting rod 39 and the horizontal direction; θ2 is the angle between the second connecting rod 40 and the horizontal direction; a is the intercept of the second connecting rod 40 below the rotating slot 41; x is the horizontal distance from the rotating slot 41 to the lock core counterweight 38, the actual size is 17.8mm; Δh is the vertical distance from the rotating slot 41 to the swing lock core 42, the actual size is 13.5mm; p is the horizontal position of the swing lock core 42.

[0084] In the locked state, the swing lock core 42 is located directly above the rotating slide groove 41, that is, p = x. Combining formulas (5) and (6), the transmission connecting rod rotation angle can be obtained:

[0085]

[0086] a=L2-Δh=42-13.5=28.5 (7)

[0087] Substituting formula (2) and (3) together, we can obtain:

[0088] h0=41.5 (8)

[0089] In the unlocked state, the right side of the swing lock core 42 is in contact with the limit portion 43, that is, p = 31.4. Combining formulas (5) and (6), we can obtain: θ2=0.782 (9)

[0091] a=22.8 (10)

[0092] Substituting formula (2) and (3) together, we can obtain:

[0093] h1=37.9 (11)

[0094] After the swing lock core 42 is in contact with the limiting portion 43, the upward movement of the lock core counterweight 38 is transformed into a downward rotation around the contact axis, and the movement model is changed as follows: Fig.17 The first locking mechanism 19 is shown in the schematic diagram, and is calculated according to the plane freedom formula:

[0095] F=3n-2P L -P H =3×5-2×7-1×0=1 (12)

[0096] It can be seen that the number of degrees of freedom of the internal transmission chain of the first locking mechanism 19 is still 1. Based on the closed chain kinematics, further calculation and derivation can be obtained to obtain the mapping relationship between the up and down translation movement of the lock core counterweight 38 and the rotation movement of the swing lock core 42 around the axis:

[0097] L1cosθ1+acosθ2=x (13)

[0098] L1sinθ1+asinθ2=h (14)

[0099] (L2-a)cosθ2+L3cosθ3=w (15)

[0100] (L2-a)sinθ2+L3sinθ3=Δh (16)

[0101] L3 is the length of the swing lock core 42 simplified as the connecting rod, the actual size is 36mm; θ3 is the angle between the swing lock core 42 simplified as the connecting rod and the horizontal direction; w is the horizontal distance from the rotating slot 41 to the rotating shaft, the actual size is 14.8mm; Δh is the vertical distance from the rotating slot 41 to the rotating shaft of the swing lock core 42, the actual size is 35.0mm;

[0102] The unlocking process requires the swing lock cylinder 42 to rotate 60 degrees around the axis, and the lower reset lever 35 is moved to make the movable coupler 31 rotate outward to unlock. Substituting into the closed loop equations (15) and (16), we can obtain:

[0103] θ2=2.27 (17)

[0104] a=27.7 (18)

[0105] Substituting (13) and (14) together, we can obtain:

[0106] h2=28.5 (19)

[0107] It can be obtained that the lead h of the process of lifting the lock core counterweight 38 so that the first locking mechanism 19 is locked to the unlocking and resetting process is:

[0108] h=h0-h2=41.5-28.5=13 (20)

[0109] The designed pullable lead L of the lock core counterweight 38 is 30, satisfying that L is greater than the lead h.

[0110] like Figure 12-Figure 15 and Fig.18 As shown, optionally, the reset assembly also includes a reset handle 36, the lower end of the locking bracket 33 is fixedly connected to the first lifting sleeve 37, the lock core counterweight 38 is slidably connected in the first lifting sleeve 37, and the side wall of the first lifting sleeve 37 is provided with an L-shaped notch portion 44, and the reset handle 36 can be horizontally rotated and lifted in the notch portion 44.

[0111] By providing an L-shaped notch 44 on the side wall of the first lifting sleeve 37, the lower part of the L-shaped notch 44 can be used to allow the reset handle 36 to rotate in the horizontal plane, and prevent external interference from causing the reset handle 36 to move upward and cause the first locking mechanism 19 to be unlocked. The vertically extending part of the L-shaped notch 44 can allow the reset handle 36 to be lifted and lowered to abut against the lock core counterweight 38 upward, thereby pushing the first locking mechanism 19 to operate.

[0112] The bottom of the notch 44 is located at the bottom of the first lifting sleeve 37, and the top of the notch 44 extends to the upper part of the first lifting sleeve 37. The reset handle 36 includes a portion extending from the first lifting sleeve 37 and a cylindrical portion that can rotate in the first lifting sleeve 37, and the inner surface of the first lifting sleeve 37 is a cylindrical surface. When the reset handle 36 rotates horizontally in a horizontal portion of the L-shaped notch 44, a gap is left between the upper surface of the cylindrical portion of the reset handle 36 and the lower end of the lock core counterweight 38. When the reset handle 36 rotates to the vertical portion of the notch 44, the reset handle 36 can only contact the lock core counterweight 38 and push the lock core counterweight 38 to rise after it rises.

[0113] like Fig.19 As shown, optionally, the bearing platform also includes a second lifting sleeve 47, which is installed at the corner of the frame assembly 17; the top of the second lifting sleeve 47 is fixedly connected to an upper limit plate 45, the bottom of the second lifting sleeve 47 is fixedly connected to a lower limit plate 46, the outer side surface of the locking bracket 33 is fixedly connected to the limit flange 34, the locking bracket 33 can be lifted and lowered in the second lifting sleeve 47, and the limit flange 34 can abut against the upper limit plate 45 or the lower limit plate 46.

[0114] By setting a second lifting sleeve 47 and setting an upper limit plate 45 and a lower limit plate 46 on the second lifting sleeve 47, the first locking mechanism 19 can slide in the second lifting sleeve 47, so that when the movable hook 31 and the fixed hook 29 do not need to be locked, the first locking mechanism 19 is lower than the upper surface of the load-bearing platform, thereby facilitating the standardized mining transport box to be transported to the precise position on the surface of the load-bearing platform.

[0115] Among them, in this embodiment, the upper limit plate 45 is in a square frame shape, that is, the outer edge is rectangular or square, and a rectangular or square through hole is provided in the middle of the upper limit plate 45, so as to facilitate the upper part of the locking bracket 33 to extend out of the upper limit plate 45. The two opposite sides of the through hole of the upper limit plate 45 also form flanges protruding inward from the inner side surface of the second lifting sleeve 47 to limit the highest position of the limit flange 34, that is, to limit the highest position of the first locking mechanism. The second lifting sleeve 47 is a tubular shape that penetrates up and down with a rectangular cross section. The lower limit plate 46 can be arranged at the bottom of the inner wall of the second lifting sleeve 47. The lower limit plate 46 is composed of two pieces, which are arranged corresponding to the limit flange 34 to limit the lowest position of the limit flange 34 moving downward, that is, to limit the lowest position of the first locking mechanism 19. From Fig.18 and Fig.15 the comparison can be seen that in Fig.15 , the bottom of the locking bracket 33 is still above the bottom of the second lifting sleeve 47, while in Fig.18 , the bottom of the locking bracket 33 has extended downward out of the bottom of the second lifting sleeve 47

[0116] As Fig. 20 and Fig.21 shown, optionally, the vehicle frame assembly 17 includes a vehicle plate body 21 and a support frame 22. The support frame 22 is fixedly connected to the bottom surface of the vehicle plate body 21. A downward-opening and closable flat plate 23 is also pivotally connected to the vehicle plate body 21. The closable flat plate 23 is locked to the vehicle plate body 21 through a second locking mechanism. The second locking mechanism includes a locking slot provided on the lower surface of the closable flat plate 23 and a locking plug 231 rotatably connected to the lower surface of the vehicle plate body 21. The locking slot is formed by a slot lower plate fixedly connected to the lower surface of the closable flat plate 23 and the closable flat plate 23. The locking plug 231 is configured to be inserted into the locking slot.

[0117] Among them, the support frame 22 is in a grid structure formed by criss-crossing support pipes. The vehicle plate body 21 is located above the grid structure. The locking plug 231 can be a rectangular plate body. The position of the locking plug 231 close to one end is rotatably connected to the vehicle plate body 21, and the rotation axis of the locking plug 231 is a vertical axis. The locking lower plate 232 is a bent plate. A part of the locking lower plate 232 is in contact with the vehicle plate body 21, and there is a gap between another part of the locking lower plate 232 and the vehicle plate body 21, and this gap forms the locking slot. When the locking plug 231 is inserted into the locking slot, the closable flat plate 23 cannot be opened. If it is necessary to open the closable flat plate 23, the locking plug 231 can be rotated out of the area of the closable flat plate 23, and the closable flat plate 23 can be opened downward.

[0118] As Fig. 22 and Fig.23As shown, optionally, the bearing platform includes a body assembly 18, the body assembly 18 includes a body cross beam 28, the body cross beam 28 is fixedly connected to the connecting base 27, a buffer 26 is provided in the connecting base 27, the buffer 26 is fixedly connected to the connecting base 27 through a connecting pin 24, the connecting pin 24 penetrates from top to bottom into a pin anti-slip ring 25 fixedly set on the top of the connecting base 27, the connecting base 27 and the buffer 26, and a horizontal pin is also provided in the connecting pin 24, and the horizontal pin passes through the horizontal plug hole of the pin anti-slip ring 25.

[0119] There are two body cross beams 28 in the body assembly 18, and the length direction of the two body cross beams 28 is consistent with the length direction of the vehicle and is arranged in parallel and spaced apart. The ends of the body cross beams 28 are fixedly connected to the connecting base 27 by rivets. A latch anti-slip ring 25 is provided on the surface of the connecting base 27, and the axis of the latch anti-slip ring 25 is arranged in the vertical direction. The side wall of the latch anti-slip ring 25 is provided with a horizontal plug hole penetrating along the wall thickness direction, and the connecting pin 24 is inserted into the latch anti-slip ring 25 in the vertical direction, and the horizontal pin passes through the horizontal plug hole in the horizontal direction and is inserted into the connecting pin 24. Since a horizontal pin is provided, and when the horizontal pin is inserted into the connecting pin 24, it overlaps with the latch anti-slip ring 25 in the vertical projection, so when the connecting pin 24 is subjected to an upward force, the connecting pin 24 can be prevented from being pulled out of the latch anti-slip ring 25.

[0120] like Fig.24 As shown, optionally, the load-bearing platform also includes a wheel assembly 20, the wheel assembly 20 includes a wheel pair 48 and an axle clamp 49, the wheel pair 48 includes a pair of wheels, the wheels are rotatably connected to the axle clamp 49 through the same wheel axle, and the axle clamp 49 is fixed to the body cross beam 28.

[0121] In this embodiment, the wheel assembly 20 includes two pairs of wheels 48, and the two pairs of wheels 48 are arranged along the length direction of the vehicle. Specifically, the wheel can be rotatably arranged relative to the wheel axle, and the axle clamp 49 is fixedly connected to the body cross beam 28 by rivets.

[0122] Embodiment three:

[0123] like Fig.25 As shown, the use method provided in the third embodiment is applied to a box transport system, the box transport system includes the above-mentioned standardized mining transport box and the above-mentioned load-bearing platform, and the use method includes a loading method and an unloading method;

[0124] The loading method includes: controlling the standardized mining transport box to move toward the carrying platform, identifying and locating the center coordinates of the corner piece; if the standardized mining transport box is aligned with the carrying platform, controlling the standardized mining transport box to be lowered onto the carrying platform, the camera identifying and locating the first locking mechanism 19 on the carrying platform, guiding the mechanical arm to lock the first locking mechanism 19; opening the lock 13 and opening the box door 12; closing the box door 12 and closing the lock 13 after loading the material into the standardized mining transport box;

[0125] The unloading method includes: after the load-bearing platform carries the standardized mining transport box to the unloading position, identifying and locating the center coordinates of the corner pieces, then identifying and locating the first locking mechanisms 19 corresponding to the corner pieces, respectively, guiding the robotic arm to unlock the first locking mechanisms 19, and controlling the standardized mining transport box to separate from the load-bearing platform.

[0126] The center coordinates of the corner fittings are identified to align the corner fittings with the first locking mechanism 19. When all corner fittings of the uncovered box are aligned with the first locking mechanism 19, the standardized mining transport box is aligned with the load-bearing platform. Then the robotic arm can be guided to lock the first locking mechanism 19, thereby improving the degree of automation of the operation process.

[0127] Confirming whether the standardized mining transport box is aligned with the load-bearing platform can be achieved by confirming whether the corner piece is aligned with the first locking mechanism 19. More specifically, the Hough straight line detection technology can be used.

[0128] The specific process of guiding the mechanical arm to lock the first locking mechanism 19 includes:

[0129] After the standardized mining transport box contacts the load platform, especially after the standardized mining transport box is loaded with materials, the camera is used to identify the first locking mechanism 19, and the mechanical arm is driven to approach the reset handle 36, and the mechanical arm drives the reset handle 36 to descend and then rotate horizontally into the bottom horizontal part of the notch 44. The lock core counterweight 38 descends, driving the first locking mechanism 19 to lock. The specific action principle of the first locking mechanism 19 locking can be found above, and will not be repeated here.

[0130] The process of guiding the mechanical arm to unlock the first locking mechanism 19 includes:

[0131] The camera is used to identify the first locking mechanism 19, and the reset handle 36 is driven to rotate horizontally from the horizontal extension part of the notch 44 to the vertical extension part of the notch 44, and the reset handle 36 is pushed upward to drive the lock core counterweight 38 to rise, thereby driving the first locking mechanism 19 to unlock. The specific action principle of unlocking the first locking mechanism 19 can be found above, and will not be repeated here.

[0132] Optionally, identifying and locating the center coordinates of the corner piece includes:

[0133] Four cameras form two binocular stereo vision systems to collect images, and synchronously collect images of the box module. After preprocessing the collected images, edge features and texture features are selected as feature vectors for box module recognition. The image edge is obtained through the edge detection algorithm, and then the contour extraction algorithm is used to extract the image contour information. The contour of the corner piece is screened out according to the contour features, and the center coordinates of the corner piece are obtained by calculating the center point of the circumscribed rectangle.

[0134] With such arrangement, when the corner piece moves into the shooting range of the camera, the center coordinates of the corner piece can be obtained visually without contact measurement, and the corner piece can be moved to the correct position without the first time, and can be identified visually within a larger range. After identification, the corner piece is controlled to be precisely aligned with the first locking mechanism 19, thereby reducing the motion accuracy requirement for the initial movement of the box module.

[0135] The edge detection algorithm may be a Canny edge detection algorithm, and the center point of the circumscribed rectangle is calculated to obtain the center left side of the corner piece, and a contour area method or a contour perimeter method may be used.
