Description

Technical Field

[0001] The present invention relates to the technical field of coal mine loading and unloading, and in particular to an automated coal mine car loading and unloading system. Background Art

[0002] The automated coal mine car loading and unloading system utilizes advanced automation technology and intelligent equipment to automate and unmanned coal mine car loading and unloading operations during transportation. This system improves work efficiency, reduces labor costs, and mitigates safety risks, while also ensuring efficient and environmentally friendly coal mine operations.

[0003] However, the existing technology cannot load and unload materials in one go, and due to the different sizes of the coal boxes in the mine cars, there are great difficulties in the loading and unloading process, and manual cooperation is required, the labor cost is high, and the loading and unloading efficiency is low. Therefore, there is an urgent need for an automated coal mine car loading and unloading system. Summary of the Invention

[0004] In response to the above technical problems, the technical solution adopted by the present invention is: an automated coal mine car loading and unloading system, including a support mechanism and two sets of closing mechanisms, the support mechanism includes a frame and two sets of slides, the two sets of slides are symmetrically mounted on the longitudinal rails of the frame for longitudinal sliding, one set of slides corresponds to one set of transverse mechanisms, the two sets of slides adjust the distance between the two sets of transverse mechanisms, the sliders at both ends of the transverse assembly of the transverse mechanism are symmetrically mounted on the slide for transverse sliding, the two sets of sliders adjust the length of the transverse assembly, L-shaped slide rails are symmetrically fixedly mounted on both ends of the transverse assembly, and the two sets of closing mechanisms are symmetrically arranged between the two sets of transverse mechanisms The closing mechanism includes multiple groups of longitudinal components and coal shoveling components. The first group of longitudinal components is rotatably installed on the top of the L-shaped slide rail, and the two ends of the remaining longitudinal components are slidably installed on the L-shaped slide rails of the two groups of transverse mechanisms. The two adjacent groups of longitudinal components are rotatably connected. The last group of longitudinal components is rotatably connected to the coal shoveling component. The rotating shaft of the coal shoveling component is rotated and slidably installed on the L-shaped empty rail of the transverse component. The coal shoveling component slides on the L-shaped empty rail to drive multiple groups of longitudinal components and two groups of transverse components to close, adapting to the size of the coal box of the mine car. The power mechanism inside the transverse component drives the coal shoveling assembly to slide on the L-shaped empty rail.

[0005] Furthermore, the support mechanism also includes two sets of transverse and bidirectional screw rods, one set of which corresponds to one set of transverse mechanisms. The transverse and bidirectional screw rods are rotatably mounted on the transverse pin seats of the slides, and the middle portions of the transverse and bidirectional screw rods are rotatably mounted on the two sets of sliders of each set of transverse mechanisms, with the transverse and bidirectional screw rods and the sliders being threadedly engaged. The transverse turntables of the transverse and bidirectional screw rods are synchronously rotated to drive the sliders of the transverse mechanisms to slide on the corresponding slides, thereby adjusting the distance between the two sets of sliders. The sliders drive the corresponding first and second transverse plates to slide toward each other, thereby changing the length of the transverse assembly to adapt to the width of the mine car coal box.

[0006] Furthermore, the transverse assembly includes a first transverse plate and a second transverse plate, which are slidably mounted between the first and second transverse plates. Two sets of L-shaped empty rails are fixedly mounted to the first and second transverse plates, respectively. A first curved frame is provided below the first transverse plate, and a second curved frame is provided below the second transverse plate. The first curved frame and the second curved frame are slidably mounted between the first and second curved frames, and the first and second curved frames are wedge-shaped. The design of the first and second curved frames facilitates the frame to drive the transverse mechanism to move toward the mine car coal box, thereby ensuring close contact between the exterior of the transverse assembly and the inner wall of the mine car coal box, confining the coal between the two sets of transverse mechanisms.

[0007] Furthermore, the support mechanism also includes a longitudinal and bidirectional screw rod, a longitudinal pin seat is provided on the slide, the ends of the longitudinal and bidirectional screw rod are rotatably mounted on the longitudinal axis seat of the frame, and the middle portion of the longitudinal and bidirectional screw rod is rotatably mounted on the longitudinal pin seats of the two sets of slides, and the longitudinal and bidirectional screw rod and the longitudinal pin seat are threadedly engaged. Rotating the longitudinal turntable of the longitudinal and bidirectional screw rod drives the longitudinal and bidirectional screw rod to rotate, and when the longitudinal and bidirectional screw rod rotates, the two sets of slides move toward each other, adjusting the distance between the two sets of slides, and thus adjusting the distance between the two sets of transverse mechanisms to adapt to the length of the mine car coal box.

[0008] Furthermore, the longitudinal assembly includes a first longitudinal plate and a second longitudinal plate, which are slidably mounted between the first and second longitudinal plates. Slide columns are symmetrically provided on the first and second longitudinal plates, and the slide columns are slidably mounted on the L-shaped slide rails of the transverse mechanism on the same side. The first and second longitudinal plates are both provided with nose pins, and the corresponding nose pins on the two adjacent sets of longitudinal assemblies are rotatably connected. When the longitudinal bidirectional screw rotates, it drives the two sets of slides to slide toward each other, and relative sliding occurs between the first and second longitudinal plates, thereby changing the length of the longitudinal assembly to adapt to the length of the mine car coal box.

[0009] Furthermore, the closure mechanism includes multiple pairs of V-shaped assemblies, each of which includes two sets of rocker arms, one set corresponding to a set of longitudinal assemblies. The ends of the rocker arms are pivotally mounted on the sliding posts of the longitudinal assemblies, and the tail ends of the rocker arms of each pair of V-shaped assemblies are pivotally connected to each other. The V-shaped assemblies ensure the folding direction of the longitudinal assemblies, thereby ensuring stable sliding of the longitudinal assemblies on the L-shaped slide rails.

[0010] Furthermore, the coal shovel assembly includes a first shovel plate and a second shovel plate, which are slidably installed between the first shovel plate and the second shovel plate. Ear pins are respectively provided on the first shovel plate and the second shovel plate, which are rotatably connected to the nose pins of the last group of longitudinal components. The rotating shaft is rotatably installed on the first shovel plate and the second shovel plate, and the distance between the L-shaped empty rail and the L-shaped slide rail is smaller than the axial center distance between the rotating shaft and the sliding column of the last group of longitudinal components. When the distance between the two sets of horizontal mechanisms changes, the first shovel plate and the second shovel plate slide relative to each other. Since the distance between the L-shaped empty rail and the L-shaped slide rail is smaller than the axial center distance between the rotating shaft and the slide column of the last set of longitudinal components, the coal shovel component is in an inclined state under the connection between the last set of longitudinal components and the coal shovel component, which facilitates the contact between the coal shovel component and the inner wall of the coal box of the mine car, separating the coal from the coal box of the mine car. When the coal shovel components of the two sets of closing mechanisms slide on the L-shaped empty rail, they drive the longitudinal components to slide on the L-shaped slide rail, thereby confining the coal within the two sets of closing mechanisms. With the assistance of the two sets of horizontal mechanisms, the coal is taken out of the coal box of the mine car.

[0011] Furthermore, the power mechanism corresponds to a set of transverse components, the power mechanism includes a first L-shaped rack and a second L-shaped rack, a hollow rail is provided inside the first transverse plate and the second transverse plate, the first L-shaped rack is fixedly installed inside the hollow rail of the first transverse plate, the second L-shaped rack is fixedly installed inside the hollow rail of the second transverse plate, the first L-shaped rack and the second L-shaped rack are slidably installed, the first L-shaped rack and the second L-shaped rack respectively correspond to a set of gears, the two sets of gears are respectively fixedly installed at the ends on the same side of the rotating shaft of the closing mechanism, and the gears are meshed with the first L-shaped rack and the second L-shaped rack. When the rotating shaft rotates, the gears are driven to rotate, and under the meshing action of the gears with the first L-shaped rack and the second L-shaped rack, the rotating shaft is driven to slide on the L-shaped hollow rail, thereby driving the longitudinal component to slide on the L-shaped slide rail, completing the seal between the closing mechanism and the transverse mechanism.

[0012] Compared with the prior art, the present invention has the following advantages: (1) the present invention is provided with a transverse mechanism, which uses a transverse bidirectional screw rod to adjust the relative position between the first transverse plate and the second transverse plate, thereby changing the length of the transverse assembly, that is, the distance between the two groups of closing mechanisms, to adapt to the width of the mine car coal box; (2) the present invention is provided with two groups of closing mechanisms, which uses a longitudinal bidirectional screw rod to adjust the distance between the two groups of slides, thereby adjusting the distance between the two groups of closing mechanisms, to adapt to the length of the mine car coal box; (3) the present invention is provided with a power mechanism, which uses the power mechanism to drive the coal shovel assembly to slide on the L-shaped empty rail, and the longitudinal assembly to slide on the L-shaped slide rail, so that the closing mechanism and the transverse mechanism confine the coal inside the mine car coal box, adapting to mine car coal boxes of different sizes, improving the efficiency of loading and unloading coal, and having a high degree of automation.

The closing mechanism includes multiple sets of longitudinal components 31. , coal shoveling assembly 33, the first group of longitudinal components 31 is rotatably installed on the top of the L-shaped slide rail 22, and the remaining longitudinal components 31 are slidably installed at both ends on the L-shaped slide rails 22 of the two groups of transverse mechanisms. The two adjacent groups of longitudinal components 31 are rotatably connected, and the last group of longitudinal components 31 is rotatably connected to the coal shoveling assembly 33. The rotating shaft 334 of the coal shoveling assembly 33 is rotatably and slidably installed on the L-shaped empty rail 25 of the transverse component 21. The coal shoveling assembly 33 slides on the L-shaped empty rail 25 to drive multiple groups of longitudinal components 31 and the two groups of transverse components 21 to be closed to adapt to the size of the mine car coal box. The power mechanism inside the transverse component 21 drives the coal shoveling assembly 33 to slide on the L-shaped empty rail 25.

[0028] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the support mechanism includes a frame 11, a slide 12, a longitudinal and bidirectional screw rod 13, and a transverse and bidirectional screw rod 14. There are two groups of slides 12. The two groups of slides 12 are symmetrically mounted on the longitudinal rail 111 of the frame 11 for longitudinal sliding. The slide 12 is provided with a longitudinal pin seat 121 and a transverse pin seat 122. The two ends of the longitudinal and bidirectional screw rod 13 are rotatably mounted on the longitudinal axis seat 112 of the frame 11. The middle part of the longitudinal and bidirectional screw rod 13 is rotatably mounted on the longitudinal pin seat 121 of the slide 12. A longitudinal turntable 131 is provided on the longitudinal and bidirectional screw rod 13, and a threaded fit between the longitudinal and bidirectional screw rod 13 and the longitudinal pin seat 121 is provided. ; Rotate the longitudinal turntable 131 of the longitudinal and bidirectional screw rod 13 to drive the longitudinal and bidirectional screw rod 13 to rotate. When the longitudinal and bidirectional screw rod 13 rotates, it drives the two groups of slides 12 to move toward each other, adjusts the distance between the two groups of slides 12, and thus adjusts the distance between the two groups of transverse mechanisms to adapt to the length of the coal box of the mine car; there are two groups of transverse bidirectional screw rods 14, one group of transverse bidirectional screw rods 14 corresponds to one group of transverse mechanisms, and one group of transverse bidirectional screw rods 14 corresponds to one group of slides 12. The transverse bidirectional screw rods 14 are rotatably installed on the transverse pin seat 122 of the slide 12, and a transverse turntable 141 is provided on the transverse bidirectional screw rod 14.

[0029] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 10 、 Figure 11 As shown, the transverse mechanism includes a transverse component 21, an L-shaped slide rail 22, and a slider 24. The transverse component 21 includes a first transverse plate 211 and a second transverse plate 212. The first transverse plate 211 is slidably installed with the second transverse plate 212. A first arc frame 2111 is provided below the first transverse plate 211, and a second arc frame 2121 is provided below the second transverse plate. The first arc frame 2111 and the second arc frame 2121 are slidably installed between them. The first arc frame 2111 and the second arc frame 2121 are wedge structures. The design of the first arc frame 2111 and the second arc frame 2121 makes it easy for the frame 11 to drive the transverse mechanism to move toward the coal box of the mine car, so that the outside of the transverse component 21 is in close contact with the inner wall of the coal box of the mine car, restricting the coal mine between the two groups of transverse mechanisms; each group of transverse mechanisms includes two groups of sliders 24, which are respectively fixed on the first transverse plate 211 and the second transverse plate 212, and the middle of the transverse bidirectional screw rod 14 is rotatably installed in each group of transverse mechanisms. The two sets of sliders 24 of the mechanism are threadedly matched with the horizontal bidirectional screw rod 14 and the slider 24, and the horizontal rotating disk 141 of the horizontal bidirectional screw rod 14 is rotated synchronously to drive the slider 24 of the horizontal mechanism to slide on the corresponding slide 12, and the distance between the two sets of sliders 24 is adjusted. The slider 24 drives the corresponding first cross plate 211 and second cross plate 212 to slide toward each other, thereby changing the length of the cross assembly 21 to adapt to the width of the coal box of the mine car; the two sets of L-shaped slide rails 22 are symmetrically fixed on the first cross plate 211 and the second cross plate 212, and the hollow rails 23 are symmetrically arranged inside the first cross plate 211 and the second cross plate 212, and the L-shaped empty rails 25 are symmetrically arranged on the first cross plate 211 and the second cross plate 212; the volume of the coal mine is large, and the gaps between the L-shaped slide rails 22 and the L-shaped empty rails 25 are smaller than those of the coal mine. There is no situation where the coal mine blocks the L-shaped slide rails 22 and the L-shaped empty rails 25, which will not affect the operation of the closing mechanism.

[0030] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 8 、 Figure 9As shown, there are two groups of closing mechanisms, and the two groups of closing mechanisms are symmetrically arranged between the two groups of horizontal mechanisms. The closing mechanism includes multiple groups of longitudinal components 31 and multiple pairs of V-shaped components. The longitudinal component 31 includes a first longitudinal plate 311 and a second longitudinal plate 312. The first longitudinal plate 311 and the second longitudinal plate 312 are slidably installed between them. Slide posts 314 are symmetrically arranged on the first longitudinal plate 311 and the second longitudinal plate 312. The slide posts 314 of the first group of longitudinal components 31 are slidably installed on the top of the L-shaped slide rail 22, and the slide posts 314 of the remaining longitudinal components 31 are slidably installed on the L-shaped slide rail 22 of the horizontal mechanism on the same side. The first longitudinal plate 311 and the second longitudinal plate 312 are both provided with nose pins 313. Adjacent The corresponding nose pins 313 on the two groups of longitudinal components 31 are rotatably connected; when the longitudinal bidirectional screw rod 13 rotates, it drives the two groups of slides 12 to slide toward each other, and then the first longitudinal plate 311 and the second longitudinal plate 312 slide relative to each other, thereby changing the length of the longitudinal component 31 to adapt to the length of the coal box of the mine car; each pair of V-shaped components includes two groups of rockers 32, one group of rockers 32 corresponds to one group of longitudinal components 31, and the ends of the rockers 32 are rotatably mounted on the sliding columns 314 of the longitudinal components 31, and the tails of the rockers 32 of each pair of V-shaped components are rotatably connected. The V-shaped component ensures the folding direction of the longitudinal component 31, thereby ensuring that the longitudinal component 31 slides stably on the L-shaped slide rail 22.

[0031] like Figure 3 、 Figure 4 、 Figure 10 、 Figure 11 、 Figure 12As shown, the closing mechanism also includes a coal shovel assembly 33, which includes a first shovel plate 331 and a second shovel plate 332. The first shovel plate 331 and the second shovel plate 332 are slidably installed between them. When the distance between the two sets of horizontal mechanisms changes, the first shovel plate 331 and the second shovel plate 332 slide relative to each other. Ear pins 333 are respectively provided on the first shovel plate 331 and the second shovel plate 332. The ear pins 333 are rotatably connected to the nose pin 313 of the last set of longitudinal components 31, and the rotating shaft 334 is rotatably installed on the first shovel plate 331 and the second shovel plate 332. The distance between the L-shaped idle rail 25 and the L-shaped slide rail 22 is less than the axial center distance between the rotating shaft 334 and the sliding column 314 of the last set of longitudinal components 31. Since the distance between the L-shaped idle rail 25 and the L-shaped slide rail 22 is less than the rotating shaft The axial center distance between the shaft 334 and the sliding column 314 of the last group of longitudinal components 31, when the last group of longitudinal components 31 is connected to the coal shoveling component 33, makes the coal shoveling component 33 in an inclined state, thereby facilitating the contact between the coal shoveling component 33 and the inner wall of the coal box of the mine car, separating the coal from the coal box of the mine car. When the coal shoveling components 33 of the two groups of closing mechanisms slide on the L-shaped empty rail 25, they drive the longitudinal components 31 to slide on the L-shaped slide rail 22, thereby restricting the coal within the two groups of closing mechanisms, and thus, with the assistance of the two groups of horizontal mechanisms, the coal is taken out of the coal box of the mine car; one group of coal shoveling components 33 corresponds to one group of motors 5, which are slidably installed inside the hollow rail 23, and the output shaft of the motor 5 is fixedly installed on the rotating shaft 334 of the coal shoveling component 33, and the motor 5 drives the rotating shaft 334 of the coal shoveling component 33 to rotate.

[0032] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 11 、 Figure 12 As shown, the power mechanism is arranged inside the hollow rail 23, and one group of power mechanisms corresponds to one group of transverse mechanisms. The power mechanism includes a first L-rack 41, a second L-rack 42, and two groups of gears 43. The first L-rack 41 is fixedly mounted inside the hollow rail 23 of the first transverse plate 211, and the second L-rack 42 is fixedly mounted inside the hollow rail 23 of the second transverse plate 212. The first L-rack 41 and the second L-rack 42 are slidably mounted between them. The gears 43 are respectively fixedly mounted on the ends on the same side of the rotating shaft 334 of the closing mechanism, and the gears 43 are meshed with the first L-rack 41 and the second L-rack 42; when the rotating shaft 334 rotates, it drives the gear 43 to rotate, and under the meshing action of the gear 43 and the first L-rack 41 and the second L-rack 42, the rotating shaft 334 is driven to slide on the L-shaped hollow rail 25, thereby driving the longitudinal component 31 to slide on the L-shaped slide rail 22, completing the sealing between the closing mechanism and the transverse mechanism.

[0033] Working Principle: The size of the automated coal mine car loading and unloading system is adjusted according to the size of the coal box of the mine car.

[0034] According to the width of the coal box of the mine car, the horizontal turntable 141 of the synchronously rotating horizontal bidirectional screw rod 14 is rotated to drive the slider 24 of the horizontal mechanism to slide on the corresponding slide 12, and the distance between the two groups of sliders 24 is adjusted. The slider 24 drives the corresponding first horizontal plate 211 and the second horizontal plate 212 to slide toward each other, thereby changing the length of the horizontal component 21 to adapt to the width of the coal box of the mine car. During this process, relative sliding occurs between the first arc frame 2111 and the second arc frame 2121, and relative sliding occurs between the first L rack 41 and the second L rack 42.

[0035] According to the length of the coal box of the mine car, the distance between the two groups of horizontal mechanisms, that is, the length of the longitudinal component 31, is adjusted, and the longitudinal turntable 131 of the longitudinal bidirectional screw rod 13 is rotated to drive the longitudinal bidirectional screw rod 13 to rotate. When the longitudinal bidirectional screw rod 13 rotates, it drives the two groups of slides 12 to move toward each other, and adjusts the distance between the two groups of slides 12, thereby adjusting the distance between the two groups of horizontal mechanisms to adapt to the length of the coal box of the mine car. During this process, relative sliding occurs between the first longitudinal plate 311 and the second longitudinal plate 312, and relative sliding occurs between the first shovel plate 331 and the second shovel plate 332.

[0036] The frame 11 of the automated coal mine car loading and unloading system is connected to a crane, and the crane is used to drive the automated coal mine car loading and unloading system to move. The crane drives the frame 11 to move toward the mine car coal box. The first arc frame 2111 and the second arc frame 2121 are wedge structures. The design of the first arc frame 2111 and the second arc frame 2121 facilitates the frame 11 to drive the transverse mechanism to move toward the mine car coal box, so that the outside of the transverse component 21 is in close contact with the inner wall of the mine car coal box, and the coal mine is confined between the two groups of transverse mechanisms. The volume of the coal mine is large, and the gaps between the L-shaped slide rails 22 and the L-shaped empty rails 25 are smaller than those of the coal mine. There is no situation where the coal mine blocks the L-shaped slide rails 22 and the L-shaped empty rails 25, and it will not affect the operation of the closing mechanism.

[0037] Until the first arc frame 2111 and the second arc frame 2121 contact the bottom of the mine car coal box, since the distance between the L-shaped empty rail 25 and the L-shaped slide rail 22 is less than the axial center distance between the rotating shaft 334 and the slide column 314 of the last set of longitudinal components 31, the coal shoveling component 33 is in an inclined state under the connection between the last set of longitudinal components 31 and the coal shoveling component 33, thereby facilitating the coal shoveling component 33 to contact the inner wall of the mine car coal box, separating the coal from the mine car coal box, starting the motor 5, and the motor 5 drives the rotating shaft 334 of the coal shoveling component 33 to rotate, and the motor 5 drives the rotating shaft 334 of the coal shoveling component 33 to rotate. When the shaft 334 rotates, it drives the gear 43 to rotate. Under the meshing action of the gear 43 and the first L-shaped rack 41 and the second L-shaped rack 42, the rotating shaft 334 is driven to slide on the L-shaped empty rail 25. That is, when the coal shoveling assembly 33 of the two sets of closing mechanisms slides on the L-shaped empty rail 25, the longitudinal assembly 31 is driven to slide on the L-shaped slide rail 22. With the assistance of the first L-shaped rack 41 and the second L-shaped rack 42, the coal mine is confined in the two sets of closing mechanisms, and then with the assistance of the two sets of horizontal mechanisms, the coal mine is taken out from the coal box of the mine car.

[0038] The frame 11 is moved to the target position by using a crane, and the motor 5 is started in reverse, so that the coal shoveling assembly 33 and the longitudinal assembly 31 are restored to their initial positions. During this process, the coal mine falls into the target position, completing the unloading of the coal mine.

[0039] Under the action of the first arc frame 2111 and the second arc frame 2121 and the coal shoveling assembly 33, the above steps are repeated in reverse to complete the loading of the coal mine.

[0040] The present invention is not limited to the above-mentioned specific implementation methods. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work are all within the scope of protection of the present invention.
