Description

Technical Field

[0001] This invention belongs to the field of coal mine transportation technology, specifically referring to a coal mine electromechanical transportation device. Background Technology

[0002] Coal mine electromechanical transportation is a crucial link in coal mine production, spanning the entire process of coal mining, tunneling, hoisting, transportation, and washing. It is a core element ensuring efficient, safe, and continuous coal mine production. During coal mine production, transportation equipment is needed to transfer coal for subsequent production. Existing coal mine electromechanical transportation equipment can only transport coal in a straight line and cannot transport it at multiple angles according to the terrain of the work area. To transport coal in different directions, workers must adjust the entire conveyor or rearrange the equipment within the work area, which is labor-intensive. Summary of the Invention

[0003] To address the aforementioned existing problems, this invention provides a coal mine electromechanical transport device that can conveniently adjust the coal mine conveying direction according to the terrain requirements of the working area. It adopts a segmented flexible structure combined with a nested structure, and is equipped with a folding stepped steering component. Through the connection of the array of folding plates with the guide mechanism and the first positioning block and the second positioning block, the transport direction between the belt-type feeding component and the unloading transport mechanism can be adjusted at multiple angles. It is suitable for complex working terrains, does not require overall adaptation and adjustment of other equipment, and is easy to operate.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: The present invention provides a coal mine electromechanical transportation device, including a belt-type feeding assembly, a folding stepped steering assembly, and a discharge transportation mechanism. The folding stepped steering assembly is connected between the belt-type feeding assembly and the discharge transportation mechanism. The belt-type feeding assembly includes a feeding frame, a conveyor belt is rotatably provided on the inner side of the feeding frame, and a dust suppression cover is provided on the upper part of the feeding frame, which is located above the conveyor belt.

[0005] Furthermore, the folding stepped steering assembly includes a transition connection mechanism, a folding rotation mechanism, and a rotation support mechanism. The transition connection mechanism is connected to the loading rack. The folding rotation mechanism is arranged in a vertical array at the lower part of the transition connection mechanism. The array of folding rotation mechanisms is movably located at the lower part of the transition connection mechanism. There are four sets of folding rotation mechanisms, and the rotation angle of each set of folding rotation mechanisms is between 10 degrees and 20 degrees, supporting steering in both left and right directions. The rotation support mechanism is movably located at the lower part of the folding rotation mechanism and is connected to the unloading and conveying mechanism.

[0006] Furthermore, the unloading and conveying mechanism includes an unloading frame and a guide mechanism. The unloading frame is connected to the rotating support mechanism, and the guide mechanism is located on the unloading frame and at the lower part of the rotating support mechanism.

[0007] Furthermore, the transition connection mechanism includes a transition plate, a material sliding ramp, and a connecting cover. The transition plate is connected to the loading rack and is located on one side of the conveyor belt. The material sliding ramp is located on the upper part of the transition plate, and its upper end is engaged with the upper end face of the conveyor belt. The connecting cover is located on the transition plate and covers the upper part of the material sliding ramp. The connecting cover is connected to the end of the dust suppression cover. The transition plate has through holes symmetrically arranged on both sides of the connecting cover. A first positioning block is slidably embedded in the lower part of the transition plate. The first positioning block is located on the side of the through holes away from the loading rack, and a spring is connected between the first positioning block and the upper wall of the transition plate.

[0008] Furthermore, the folding and rotating mechanism includes a folding plate and a second positioning block. The folding plate is movably disposed below the transition plate, and the second positioning block is slidably embedded in the lower part of the folding plate. A limit spring is connected between the second positioning block and the upper wall of the folding plate. The first positioning block and the second positioning block have the same size and structure. The bottoms of the first positioning block and the second positioning block are inclined, and the inclined surfaces of the first positioning block and the second positioning block face the unloading and conveying mechanism. The first positioning block can be completely embedded in the transition plate, and the second positioning block can be completely embedded in the folding plate.

[0009] Preferably, the folding plate is symmetrically provided with a first traction hole and a first arc groove. The first traction hole is located in the middle of the first arc groove, and the center of the arc trajectory of the first arc groove on one side coincides with the center of the first traction hole on the other side. When the folding plate is reset, the second positioning block of the upper layer slides in the first arc groove of the lower folding plate until the upper wall of the folding plate is pressed against the inclined surface of the second positioning block of the upper layer, and the second positioning block is pressed upward, the limiting spring is compressed, and it is completely pressed and embedded in the upper folding plate.

[0010] Furthermore, the rotating support mechanism includes a support plate connected to the end of the unloading rack. The support plate is movably disposed at the lower part of the lowest layer of the folding plate. The support plate is symmetrically provided with a second traction hole and a second arc groove. The second traction hole is located in the middle of the second arc groove. The center of the arc trajectory of the second arc groove on one side coincides with the center of the second traction hole on the other side, ensuring that when the support plate and the folding plate rotate, the first positioning block and the second positioning block can slide in the first arc groove and the second arc groove, respectively.

[0011] Preferably, the transition plate, the folding plate, and the support plate have the same structure and size. The diameters of the first traction hole, the second traction hole, and the through hole are equal. When the transition plate, the folding plate, and the support plate are arranged in an overlapping manner, the through hole, the first traction hole, and the second traction hole coincide in the vertical direction. The first arc groove and the second arc groove coincide in the vertical direction. The second positioning block is located at the end of the first arc groove and is below the first positioning block. The first positioning block slides in the uppermost first arc groove, and the array of second positioning blocks slides in the lower first arc grooves respectively. The lowermost second positioning block slides in the second arc groove.

[0012] Furthermore, the folding plate and the support plate of the array are respectively provided with shielding frames on the side away from the connecting cover. The shielding frames are arranged in a U-shape and are nested from top to bottom. The size of the upper shielding frame is smaller than that of the lower frame. The distance from the lower shielding frame to the corresponding support plate or folding plate is greater than the distance from the upper shielding frame to the corresponding folding plate. Connecting elastic elements are connected between the uppermost shielding frame and the connecting cover, as well as between adjacent shielding frames. The connecting elastic elements are symmetrically arranged on both sides of the shielding frame. The connecting elastic elements are made of rubber. The lower ends of multiple sets of connecting elastic elements are respectively attached to the upper walls of the folding plate and the support plate. The setting of the connecting elastic elements can adaptively stretch or contract according to the deflection of the folding plate to prevent the coal from sliding out during transportation.

[0013] Furthermore, the lower part of the transition plate and the folded plate of the array are respectively provided with a clearance groove, which penetrates the side wall of the transition plate and the folded plate away from the belt feeding assembly. The clearance groove is located inside the shielding frame, and a pushing mechanism is provided in the clearance groove.

[0014] Preferably, the pushing mechanism includes a first pushing plate and a second pushing plate, which are symmetrically rotated within a relief groove. The first and second pushing plates have the same structure and size, and are respectively arranged in a quarter-circle shape. The rotation centers of the first and second pushing plates are close to their respective centers. The first and second pushing plates are driven by pushing motors, which are embedded inside the transition plate and the folding plate. In the initial state, the right-angled sidewalls of the first and second pushing plates that are far apart from each other are on the same plane as the sidewalls of the transition plate and the folding plate that are far away from the belt-type feeding assembly.

[0015] In operation, when the material conveying mechanism turns to the right, the rotation angle of the first pusher plate on the left is greater than that of the second pusher plate on the right. The larger rotation angle of the first pusher plate results in a wider scraping range, creating a combined force to the right. The pusher motor starts, causing the first and second pusher plates to rotate simultaneously, moving out of the clearance groove. The right-angled edges of the first and second pusher plates scrape the coal from the lower folding plate onto the next folding plate. Meanwhile, the continuously conveyed coal falls synchronously onto the first and second pusher plates. As the first and second pusher plates return... When the material is transferred to the yielding trough, the side wall of the folding plate connected to the pushing mechanism scrapes the coal ore off the first and second pushing plates. The coal ore falls onto the lower folding plate, and so on. The pushing motor causes the first and second pushing plates to reciprocate. The rotation angle of the first pushing plate on the left is greater than that of the second pushing plate on the right, continuously pushing the coal ore falling from the upper layer, so that the coal ore is transferred and transported between the rotating stepped folding plates. Similarly, when the material conveying mechanism turns to the left, the rotation angle of the first pushing plate on the left is set to be less than that of the second pushing plate on the right.

[0016] Furthermore, the guiding mechanism includes a movable frame and an electric telescopic column. The movable frame is connected to the unloading frame, and the electric telescopic column is symmetrically arranged on the upper part of the movable frame and on the lower part of the support plate. The output end of the electric telescopic column movably passes through the second traction hole, the first traction hole, and the insertion hole. A discharge belt is rotatably wound around the inner side of the unloading frame. A power motor is provided on the side wall of the unloading frame, and the discharge belt is driven to rotate by the power motor. A discharge ramp is provided on the inner side of the shielding frame on the support plate, and the discharge ramp is connected between the support plate and the upper wall of the discharge belt.

[0017] Furthermore, the lower parts of the loading rack and the unloading rack are each equipped with casters. The loading rack has a loading port, and the dust suppression hood has a baffle plate at the end near the loading port. The baffle plate is inclined above the conveyor belt. A material leveling motor is provided on the side wall of the dust suppression hood, and a material leveling screw is provided at the output end of the material leveling motor. A actuating plate is engaged with the material leveling screw. The actuating plate slides on the baffle plate. Coal is fed into the loading port, the conveyor belt rotates and transports it, the baffle plate blocks excess coal, the material leveling motor starts, causing the material leveling screw to rotate alternately in the forward and reverse directions, thereby causing the actuating plate engaged with it to slide back and forth on the baffle plate. The coal blocked on the actuating plate is evenly spread out, preventing coal accumulation.

[0018] Preferably, the feeding rack is equipped with a main controller, which is a PLC controller, model Siemens S7-300. The main controller is electrically connected to the conveyor belt, the material leveling motor, the material pushing motor, the electric telescopic column and the power motor respectively. The casters are controlled by a remote control.

[0019] The beneficial effects of the present invention using the above structure are as follows: The present invention provides a coal mine electromechanical transportation device that can conveniently adjust the coal mine conveying direction according to the terrain requirements of the working area. It adopts a segmented flexible structure combined with a nested structure, and is equipped with a folding stepped steering component. Through the connection of the array of folding plates with the guide mechanism and the first positioning block and the second positioning block, a rotating stepped transportation channel is formed, which allows the transportation direction between the belt-type feeding component and the unloading transportation mechanism to be adjusted at multiple angles. It is suitable for complex working terrain, and does not require overall adaptation and adjustment of other equipment. Only the position of the unloading transportation mechanism needs to be rotated, making the operation convenient. Attached Figure Description

A first positioning block 12 is slidably embedded in the lower part of the transition plate 8, located on the side of the through hole 11 away from the loading rack 30. A spring is connected between the first positioning block 12 and the upper wall of the transition plate 8.

[0038] The folding and rotating mechanism 5 includes a folding plate 17, which is movably disposed below the transition plate 8. A second positioning block 20 is slidably embedded in the lower part of the folding plate 17. A limit spring 21 connects the second positioning block 20 and the upper wall of the folding plate 17. The first positioning block 12 and the second positioning block 20 are the same size and structure. The bottoms of the first positioning block 12 and the second positioning block 20 are inclined, and the inclined surfaces of the first positioning block 12 and the second positioning block 20 face the unloading and conveying mechanism 3.

The rotating support mechanism 6 includes... The support plate 24 is connected to the end of the unloading rack 38. The support plate 24 is movably disposed under the lower part of the bottommost folding plate 17. The folding plate 17 is symmetrically provided with a first traction hole 18 and a first arc groove 19. The first traction hole 18 is located in the middle of the first arc groove 19. The center of the arc trajectory of the first arc groove 19 on one side coincides with the center of the first traction hole 18 on the other side.

The center of the arc trajectory of the second arc groove 26 on one side coincides with the center of the second traction hole 25 on the other side.

[0039] The transition plate 8, folding plate 17, and support plate 24 have the same structure and size. The diameters of the first traction hole 18, the second traction hole 25, and the through hole 11 are equal. The electric telescopic column 29 is located at the lower part of the support plate 24. The output end of the electric telescopic column 29 can move through the second traction hole 25, the first traction hole 18, and the through hole 11.

[0041] The lower portions of the transition plate 8 and the array of folded plates 17 are respectively provided with clearance grooves 13. The clearance grooves 13 penetrate the sidewalls of the transition plate 8 and the folded plates 17 away from the belt-type feeding assembly 1.

The rotation centers of the first pusher plate 15 and the second pusher plate 16 are close to their respective centers. The first pusher plate 15 and the second pusher plate 16 are respectively driven by a pusher motor, which is embedded in the transition plate 8 and the folding plate 17. In the initial state, the right-angled sidewalls of the first pusher plate 15 and the second pusher plate 16 that are far apart from each other are on the same plane as the sidewalls of the transition plate 8 and the folding plate 17 that are far away from the belt feeding assembly 1.

[0042] The feeding rack 30 is equipped with a main controller 31, which is a PLC controller. The main controller 31 is electrically connected to the conveyor belt 32, the material leveling motor 35, the material pushing motor, the electric telescopic column 29 and the power motor 39.

[0043] Working principle and workflow:

[0044] In practical use, when the coal mine transportation site is relatively open and no turning is required, the conveyor belt feeding assembly 1 and the unloading transportation mechanism 3 are in a straight line. The folding stepped turning assembly 2 is retracted, and the transition plate 8, the array of folding plates 17, and the support plate 24 are stacked. At this time, the output end of the symmetrical electric telescopic column 29 is extended and is inserted into the symmetrical second traction hole 25, the first traction hole 18, and the insertion hole 11, respectively. The first positioning block 12 is pressed by the lower folding plate 17 and is completely embedded in the transition plate 8. The second positioning block 20 is pressed by its lower folding plate 17 or the support plate 24 and is completely embedded. Inside the folding plate 17, multiple sets of shielding frames 22 are nested from top to bottom, and the connecting elastic elements 23 are all in a retracted state. Coal is fed into the feed port 33. The main controller 31 controls the conveyor belt 32 to rotate and transport the coal. The baffle plate 34 blocks excess coal. The uniform motor 35 is started, causing the uniform screw to rotate alternately in the forward and reverse directions, which in turn causes the actuating plate 36, which meshes with it, to slide back and forth on the baffle plate 34. The coal blocked on the actuating baffle plate 34 is evenly spread to avoid coal accumulation. The coal is transported to the sliding slope 9 by the conveyor belt 32 and falls directly from the sliding slope 9 to the discharge slope 27, and then is transported by the discharge belt 40.

[0045] When the terrain of the coal mine transportation site is complex, and the feeding point of the belt-type feeding assembly 1 and the discharge point of the unloading transportation mechanism 3 are not on the same straight line, it is necessary to rotate the unloading transportation mechanism 3 and the belt-type feeding assembly 1 at a certain angle. At this time, taking the transportation direction as positive, the unloading transportation mechanism 3 can be deflected to the left or right relative to the belt-type feeding assembly 1 by controlling the universal wheels on the unloading frame 38. Taking the unloading transportation mechanism 3 turning to the right as an example, at this time, the electric telescopic column 29 on the left is fully retracted, and only the electric telescopic column 29 on the right penetrates the right side of the first... The second traction hole 25, the first traction hole 18, and the insertion hole 11 are used for positioning. Then, the universal wheels on the unloading rack 38 are controlled to move, so that the unloading transport mechanism 3 as a whole turns relative to the belt-type loading assembly 1. At this time, the folding stepped steering assembly 2 rotates around the axis of the electric telescopic column 29 on the right side as the rotation center. Under the drive of the guide mechanism 7, the support plate 24 rotates first, with a maximum rotation angle of 20 degrees. The second positioning block 20 on the bottom folding plate 17 slides in the second arc groove 26. As the unloading transport mechanism 3 continues to rotate, the second positioning block 20 slides. As the second arc groove 26 approaches the end of the folding plate 17, it then drives the bottom folding plate 17 to rotate around the right-side electric telescopic column 29. The upper wall of the bottom folding plate 17 no longer presses against the second positioning block 20 on the left side above it. Under the elastic action of the limiting spring 21, the second positioning block 20 on this side pops out into the first arc groove 19 of the bottom folding plate 17 and slides in the first arc groove 19 as the folding plate 17 rotates until the bottom folding plate 17 rotates to its maximum angle, thereby driving the upper folding plate 17 to continue to deflect, and so on. The folding and rotating mechanism 5 has four sets. With the rotation of the support plate 24, the material unloading and conveying mechanism 3 can rotate up to 100 degrees relative to the belt-type feeding assembly 1. During this process, the folding plate 17 and the shielding frame 22 on the support plate 24 rotate together. The left side of the shielding frame 22 rotates and opens up in sequence, while the right side of the shielding frame 22 rotates and closes up. This causes the connecting elastic member 23 on the left side to stretch and the connecting elastic member 23 on the right side to contract. The extended connecting elastic member 23 on the left side, connected by the shielding frame 22, prevents coal from leaking out from the left side of the folding plate 17 or the support plate 24.

[0046] After adjusting the overall steering angle of the material conveying mechanism 3, the pushing mechanism 14 on the deflected folding plate 17 moves in a direction that matches the rotation direction. The transition plate 8, the deflected folding plate 17, and the support plate 24 form a rotating stepped structure. When transporting coal, the coal falls through the sliding ramp 9 onto the deflected folding plate 17. The connecting elastic element 23 on the left side of the folding plate 17 prevents the coal from sliding out. At this time, the pushing mechanism 14 on the upper layer of the folding plate 17 works, the pushing motor starts, and the first pushing plate 15 on the left and the second pushing plate 16 on the right rotate simultaneously, rotating out of the clearance groove 13. The rotation angle of the first pushing plate 15 is set to be greater than that of the second pushing plate 16. The larger rotation angle of the first pushing plate 15 results in a wider scraping range. The right-angled edges of the first and second pusher plates 15 and 16, acting as a resultant force to the right, scrape the coal ore on the folding plate 17 onto the next layer of folding plate 17. Simultaneously, the continuously conveyed coal ore falls onto the first and second pusher plates 15 and 16. As the first and second pusher plates 15 and 16 rotate and retract into the clearance groove 13, the side wall of the folding plate 17, connected to the pushing mechanism 14, scrapes the coal ore off the first and second pusher plates 15 and 16, allowing it to fall onto the next layer of folding plate 17. This process continues until the coal ore falls onto the support plate 24, and the lowest-level pushing mechanism 14 pushes it onto the discharge ramp 27, ultimately placing it onto the discharge belt 40 for transport. The pushing motor causes the first and second pusher plates 15 and 16 to reciprocate. The first pusher plate 15 on the left rotates at a greater angle than the second pusher plate 16 on the right, continuously pushing the coal falling from the upper layer, allowing the coal to be transferred and transported between the rotating stepped folding plates 17. After adjusting the overall turning angle of the unloading and transporting mechanism 3, the pusher mechanisms 14 on the deflected folding plates 17 all face the direction of rotation. The transition plate 8, the deflected folding plates 17, and the support plate 24 form a rotating stepped structure. When transporting coal, the coal falls through the sliding ramp 9 and lands on the deflected folding plates 17. The connecting elastic element 23 on the left side of the folding plate 17 prevents the coal from sliding out. At this time, the pusher mechanism 14 on the upper layer of the folding plate 17 works, the pusher motor starts, and the first pusher plate 15 on the left and the second pusher plate 16 on the right rotate simultaneously. The first pusher plate 15 rotates at a greater angle than the second pusher plate 16. The right-angled edges of the first pusher plate 15 and the second pusher plate 16 scrape the coal on the folding plate 17 to the next layer of folding plate 17. Meanwhile, the continuously conveyed coal falls onto the first pusher plate 15 and the second pusher plate 16. When the first pusher plate 15 and the second pusher plate 16 rotate back into the yielding groove 13, the side wall of the folding plate 17 connected to the pushing mechanism 14 scrapes the coal off the first pusher plate 15 and the second pusher plate 16. The coal falls onto the next layer of folding plate 17, and so on, until the coal falls onto the support plate 24. The lowest pushing mechanism 14 pushes the coal onto the discharge ramp 27, and finally onto the discharge belt 40, where it is transported.The pusher motor causes the first pusher plate 15 and the second pusher plate 16 to reciprocate. The rotation angle of the first pusher plate 15 on the left is greater than that of the second pusher plate 16 on the right, continuously pushing the coal falling from the upper layer, so that the coal is transferred and transported between the rotating stepped folding plates 17.

[0047] When the coal transportation is completed and the folding stepped steering assembly 2 is retracted, the unloading and transporting mechanism 3 is reset by controlling the casters on the unloading rack 38. The guide mechanism 7 drives the support plate 24 to rotate, and the bottommost second positioning block 20 slides in the second arc groove 26 until it slides to the end of the second arc groove 26 away from the folding plate 17. Under the continuous push of the support plate 24, the bottommost folding plate 17 rotates, and the uppermost second positioning block 20 slides in the first arc groove 19 of the folding plate 17 until the upper wall of the folding plate 17 presses against the tilt of the uppermost second positioning block 20. The inclined plane is pressed upwards, and the second positioning block 20 is squeezed and moved upwards. The limiting spring 21 is compressed, so that it is completely squeezed and embedded in the upper folding plate 17. This process is repeated until all the folding plates 17 are turned back to the bottom of the transition plate 8 and folded up. During this process, after the first layer of folding plates 17 is folded up, the output end of the electric telescopic column 29 on the left side gradually extends. The output end of the electric telescopic column 29 is inserted into the second traction hole 25, the first traction hole 18 in sequence, and finally inserted into the insertion hole 11, positioning the entire folding stepped steering assembly 2. Meanwhile, the shielding frame 22 turns back to the nested position in sequence, and the connecting elastic element 23 retracts.

[0048] Similarly, when the material conveying mechanism 3 needs to turn to the left, following the steps above, simply retract the electric telescopic column 29 on the right and deflect the material conveying mechanism 3 to the left, setting the rotation angle of the first push plate 15 on the left to be less than the rotation angle of the second push plate 16 on the right.

[0049] It is worth noting that the transition plate 8, the folding plate 17 and the support plate 24 are stacked one on top of the other. Even when the support plate 24 or a certain layer of folding plate 17 rotates, there is still a large overlap between it and the upper layer of folding plate 17 or transition plate 8. There is a large friction between the folding plates 17. Therefore, the folding plate 17 will not rotate arbitrarily without external force. This will not be elaborated further here.

[0050] The above is the overall workflow of this invention. Simply repeat this process the next time you use it.
