Description

Technical Field

[0001] This invention relates to the field of conveyor technology, and more specifically to a coal-fueled dual-drive conveyor. Background Technology

[0002] Coal is an important fossil fuel, mainly formed from the remains of ancient plants through long-term geological processes. It has the characteristics of high energy density and abundant reserves. It is widely used in power generation, metallurgy, chemical industry and other fields. It releases heat energy through combustion or is converted into derivative energy such as coke and coal gas. In the process of coal processing, especially in the coal preparation process of coking plants, the reversible conveyor belt system is one of the key pieces of equipment in modern coking production. It undertakes the important task of efficiently and continuously transporting raw coal from the coal storage yard to the coal blending process.

[0003] However, most existing reversible conveyor belt systems in the coal preparation process of coking plants currently use dual-drive conveyors. Although they have the advantages of flexibly adjusting the conveying direction and speed, they also have the following main disadvantages: dual-motor drive systems require independent control systems (such as frequency converters and synchronization modules), resulting in significantly higher procurement costs than single-drive systems. In addition, dual-motor synchronous control is difficult, and the two drive units must be strictly synchronized. If the switching synchronization is insufficient, it may cause belt misalignment or material spillage, increasing operational risks. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a coal fuel dual-drive conveyor to solve the problems existing in the background art.

[0005] This invention provides the following technical solution: a coal fuel dual-drive conveyor, including a conveyor support, a conveyor belt movably connected inside the conveyor support, a synchronous control box fixedly connected to one side of the surface of the conveyor support, motor mounting plates fixedly connected to both sides of the synchronous control box near the bottom, a conveyor motor fixedly connected to the top of the motor mounting plate, a power supply component fixedly connected to the bottom of the synchronous control box, a synchronous switch movably sleeved at the top of the synchronous control box, a connecting block movably connected to the bottom of the synchronous switch, a conveyor starter box fixedly connected inside the synchronous control box near the surface of the conveyor support, and conveyor rollers movably sleeved on adjacent sides of the conveyor support. The conveyor rollers are movably sleeved on both sides inside the conveyor belt. Through the synchronous switch, connecting block, and power supply component, it is convenient to connect the conveyor motor to the same power supply component and start the conveyor motor by mechanically driving the circuit connection, thereby reducing the procurement cost of control systems such as frequency converters and synchronous modules.

[0006] Furthermore, the conveying roller includes a connecting rod, with a connector fixedly connected to one end of the connecting rod near the conveyor belt. The connector has regularly arranged rectangular mating grooves on its inner wall around its perimeter. A limit head is fixedly connected to the other end of the connecting rod away from the connector. The rectangular mating grooves on the inner wall of the connector facilitate engagement and restriction when the conveyor motor starts rotating, thereby enabling the start of the conveyor motor to drive the entire conveying roller to rotate and complete the conveying operation.

[0007] Furthermore, fixing blocks are fixedly connected to both sides of the connecting block surface, and electrical contact blocks are fixedly connected to the bottom of each fixing block. Power lines are fixedly connected to the side of the conveyor motor near the conveyor belt, with the other end of each power line fixedly connected to the surface of the power supply component. First line connectors are fixedly connected to adjacent positions on the surface of the power supply line of the conveyor motor, and second line connectors are fixedly connected to the side of the power supply component near the second line connector. The first and second line connectors are close to each other inside the conveyor belt, and electrical contact blocks are movably connected to the top adjacent positions of the first and second line connectors. Adjusting rods are movably connected to both sides of the conveyor starter box surface. Through the conveyor starter box, synchronous switch, connecting block, fixing block, electrical contact block, first line connector, and second line connector, it is beneficial that when the conveyor motor starts, the synchronous switch drives the connecting block, fixing block, and electrical contact block to descend, allowing the electrical contact blocks to connect and energize the first and second line connectors. This enables the conveyor motor to rotate synchronously under the same power supply, and the mechanical drive connection method reduces the procurement cost of control systems such as frequency converters and synchronous modules.

[0008] Furthermore, a rotating shaft is provided on the side of the conveying motor near the conveying bracket. A limiting collar is movably sleeved on the surface of the rotating shaft. One side of the limiting collar is fixedly connected to the end of the adjusting rod away from the conveying start box. The limiting collar helps to restrict the position of the telescopic docking plate inside the rotating shaft when the conveying motor starts and drives it to rotate, thus preventing it from connecting with the conveying roller.

[0009] Furthermore, the rotating shaft has regularly arranged rectangular grooves on its surface, and telescopic connecting plates are movably fitted inside each of the rectangular grooves. The telescopic connecting plates facilitate the extension and retraction of the telescopic connecting plates under the action of centrifugal force, thereby connecting the conveyor motor and the conveyor roller to drive the conveyor belt to complete the coal conveying operation.

[0010] Furthermore, limit plates are fixedly connected to the surface of the telescopic docking plate near the bottom, and regularly arranged limit posts are fixedly connected to the bottom of the telescopic docking plate. Fixed sleeves are movably sleeved on the surface of each limit post, and limiting springs are movably sleeved inside each fixed sleeve. Through the limit plates and limiting springs, the position of the telescopic docking plate is limited by the limit plates when it extends or retracts due to centrifugal force, preventing it from detaching from the rotation axis. At the same time, the limiting springs cause the telescopic docking plate to reset when the conveyor motor stops.

[0011] Furthermore, a pressure-sensitive telescopic rod is movably sleeved inside the conveying start box near the bottom of the connecting block. Rectangular telescopic rods are movably sleeved on both sides inside the conveying start box near the other end of the pressure-sensitive telescopic rod. A return spring is fixedly connected to the opposite ends of each rectangular telescopic rod. A pressing moving block is movably sleeved inside the side of each rectangular telescopic rod away from the conveying support. A miniature spring is fixedly connected to the end of the pressing moving block away from the rectangular telescopic rod. One side of the surface of the pressing moving block is fixedly connected to the end of the adjusting rod near the conveying start box. A pressing ball is fixedly connected to the opposite ends of the pressure-sensitive telescopic rod and the rectangular telescopic rod. This allows for the conveying... The system includes a starter box, a pressure-sensitive telescopic rod, a rectangular telescopic rod, a pressing moving block, an adjusting rod, a limit collar, a rotating shaft, and a telescopic docking plate. This facilitates synchronized idling after the conveyor motor is powered on. Upon activation of the synchronization switch, the pressure-sensitive telescopic rod presses against the rectangular telescopic rod, which in turn moves the pressing moving block, adjusting rod, and limit collar. The centrifugal force generated by the rotating shaft then connects the telescopic docking plate to the conveyor rollers, driving the conveyor belt. This further improves the synchronization effect of the conveyor motor, reduces the difficulty of synchronization control, avoids belt misalignment or material spillage due to insufficient synchronization, and reduces operational risks.

[0012] Furthermore, a conical groove is provided at the position where the rectangular telescopic rod is movably connected to the extrusion moving block. A conical extrusion head is fixedly connected to the extrusion moving block near the side of the rectangular telescopic rod. Through the conical groove and the conical extrusion head, it is beneficial to extrude and retract the conical extrusion head when the rectangular telescopic rod moves, thereby causing the extrusion moving block to drive the adjusting rod and the limiting collar to move.

[0013] Furthermore, the synchronous switch includes a threaded rod, one end of which is fixedly connected to a limit slide plate inside the connecting block. A rotary valve is fixedly connected to the surface of the threaded rod near the top. A compression piston rod is movably sleeved inside the threaded rod. The synchronous switch helps to prevent the compression piston rod inside from starting when the switch is lowered and energized, thereby increasing the safety of its actual operation.

[0014] The technical effects and advantages of this invention are as follows:

[0015] 1. This invention, by including a conveyor starter box, a synchronous switch, a connecting block, a fixing block, a power connection block, a first line connector, and a second line connector, facilitates the following when the conveyor motor is started: the synchronous switch drives the connecting block, the fixing block, and the power connection block to descend, allowing the power connection block to connect and energize the first line connector and the second line connector. This enables the conveyor motor to rotate synchronously under the same power supply and starts using a mechanical drive line connection method, reducing the procurement cost of control systems such as frequency converters and synchronous modules.

[0016] 2. This invention, by incorporating a conveyor start-up box, a pressure-sensitive telescopic rod, a rectangular telescopic rod, a pressing moving block, an adjusting rod, a limiting collar, a rotating shaft, and a telescopic docking plate, facilitates idling synchronization after the conveyor motor is powered on and started. Upon activation of the synchronization switch, the pressure-sensitive telescopic rod presses against the rectangular telescopic rod, causing the rectangular telescopic rod to push the pressing moving block, adjusting rod, and limiting collar to move. The centrifugal force generated by the rotating shaft then connects the telescopic docking plate with the conveyor roller, driving the conveyor belt for transport. This further improves the synchronization effect of the conveyor motor and reduces the difficulty of synchronization control, preventing insufficient synchronization that could lead to belt misalignment or material spillage, thus reducing operational risks.

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The coal fuel dual-drive conveyor involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Reference Figures 1-11 As shown, the present invention provides a coal fuel dual-drive conveyor, including a conveyor support 1, a conveyor belt 2 movably connected inside the conveyor support 1, a synchronous control box 3 fixedly connected to one side of the surface of the conveyor support 1, motor mounting plates 4 fixedly connected to both sides of the surface of the synchronous control box 3 near the bottom, a conveyor motor 5 fixedly connected to the top of the motor mounting plate 4, a power supply component 6 fixedly connected to the bottom of the inside of the synchronous control box 3, a synchronous switch 7 movably sleeved at the top of the synchronous control box 3, a connecting block 9 movably connected to the bottom of the synchronous switch 7, a conveyor starter box 8 fixedly connected inside the synchronous control box 3 near the surface of the conveyor support 1, and conveyor rollers 10 movably sleeved on both adjacent sides of the conveyor support 1, the conveyor rollers 10 being movably sleeved on both sides inside the conveyor belt 2;

[0031] In this embodiment, the synchronous switch 7, connecting block 9, and power supply component 6 facilitate the connection of the conveyor motor 5 to the same power supply component 6, and the conveyor motor 5 is started by mechanically driving the circuit connection, thereby reducing the procurement cost of control systems such as frequency converters and synchronous modules.

[0032] The conveyor roller 10 includes a connecting rod 1001. A connector 1003 is fixedly connected to one end of the connecting rod 1001 near the conveyor belt 2. A regularly arranged rectangular docking groove 1004 is opened around the inner wall of the connector 1003. A limit head 1002 is fixedly connected to one end of the connecting rod 1001 away from the connector 1003.

[0033] In this embodiment, the rectangular docking groove 1004 opened around the inner wall of the connector 1003 facilitates engagement and restriction with the rectangular docking groove 1004 when the conveying motor 5 starts to rotate, thereby enabling the start of the conveying motor 5 to drive the conveying roller 10 to rotate as a whole to complete the conveying operation.

[0034] Among them, fixing blocks 11 are fixedly connected to both sides of the surface of the connecting block 9, and electrical connection blocks 12 are fixedly connected to the bottom of the fixing blocks 11. Power lines 13 are fixedly connected to the side of the conveyor motor 5 near the conveyor belt 2. The other end of the power line 13 is fixedly connected to the surface of the power component 6. First line connectors 14 are fixedly connected to the adjacent positions of the surface of the conveyor motor 5 and the power line 13. Second line connectors 15 are fixedly connected to the side of the surface of the power component 6 near the second line connector 15. The first line connectors 14 and the second line connectors 15 are close to each other inside the conveyor belt 2. Electrical connection blocks 12 are movably connected to the adjacent top positions of the first line connectors 14 and the second line connectors 15. Adjusting rods 16 are movably connected to both sides of the surface of the conveyor starter box 8.

[0035] In this embodiment, by using the conveyor starter box 8, synchronous switch 7, connecting block 9, fixing block 11, power connection block, first line connector 14, and second line connector 15, it is beneficial that when the conveyor motor 5 is started, the synchronous switch 7 drives the connecting block 9, fixing block 11, and power connection block 12 to descend, so that the power connection block 12 connects and energizes the first line connector 14 and the second line connector 15, thereby enabling the conveyor motor 5 to rotate synchronously under the same power supply and start by mechanically driving the line connection, reducing the procurement cost of control systems such as frequency converters and synchronous modules.

[0036] Among them, the conveyor motor 5 has a rotating shaft 17 on the side near the conveyor bracket 1. A limiting collar 18 is movably sleeved on the surface of the rotating shaft 17. One side of the limiting collar 18 is fixedly connected to the end of the adjusting rod 16 away from the conveyor start box 8.

[0037] In this embodiment, the limiting collar 18 helps to restrict the position of the telescopic docking plate 19 inside the conveyor motor 5 to prevent it from connecting with the conveyor roller 10 when the conveyor motor 5 starts and drives the rotating shaft 17 to rotate.

[0038] The rotating shaft 17 has regularly arranged rectangular grooves 1701 on its surface, and telescopic docking plates 19 are movably fitted inside the rectangular grooves 1701.

[0039] In this embodiment: the telescopic docking plate 19 is used to extend and retract under the action of centrifugal force, thereby connecting the conveying motor 5 with the conveying roller 10 to drive the conveying belt 2 to complete the coal conveying operation.

[0040] Among them, the telescopic docking plate 19 is fixedly connected to the bottom position of the surface of the telescopic docking plate 19, and the bottom position of the telescopic docking plate 19 is fixedly connected to the regularly arranged limiting posts 1902. The surface of the limiting posts 1902 is movably sleeved with the fixing sleeve 1903, and the inside of the fixing sleeve 1903 is movably sleeved with the limiting spring 1904.

[0041] In this embodiment, the limiting plate 1901 and the limiting spring 1904 help to limit the position of the telescopic docking plate 19 when it extends or retracts due to centrifugal force, preventing it from detaching from the rotating shaft 17. At the same time, the limiting spring 1904 enables the telescopic docking plate 19 to reset when the conveying motor 5 stops.

[0042] Inside the conveying start box 8, near the bottom of the connecting block 9, a touch-sensitive telescopic rod 20 is movably sleeved. Inside the conveying start box 8, near the other end of the touch-sensitive telescopic rod 20, rectangular telescopic rods 21 are movably sleeved on both sides. The ends of the rectangular telescopic rods 21 that are far apart from each other are fixedly connected to a return spring 22. Inside the side of the rectangular telescopic rod 21 that is far away from the conveying bracket 1, a pressing moving block 23 is movably sleeved. The end of the pressing moving block 23 that is far away from the rectangular telescopic rod 21 is fixedly connected to a miniature spring 24. One side of the surface of the pressing moving block 23 is fixedly connected to the end of the adjusting rod 16 near the conveying start box 8. The ends of the touch-sensitive telescopic rod 20 and the rectangular telescopic rod 21 that are close to each other are fixedly connected to a pressing ball.

[0043] In this embodiment, the conveyor starter box 8, the pressure telescopic rod 20, the rectangular telescopic rod 21, the extrusion moving block 23, the adjusting rod 16, the limiting collar 18, the rotating shaft 17, and the telescopic docking plate 19 facilitate idling synchronization after the conveyor motor 5 is powered on and started. With the activation of the synchronization switch 7, the pressure telescopic rod 20 presses against the rectangular telescopic rod 21, causing the rectangular telescopic rod 21 to push the extrusion moving block 23, the adjusting rod 16, and the limiting collar 18 to move. The centrifugal force generated by the rotation of the rotating shaft 17 drives the telescopic docking plate 19 to connect with the conveyor roller 10, thereby driving the conveyor belt 2 for conveying. This further improves the synchronization effect of the conveyor motor 5 and reduces the difficulty of synchronization control, avoiding insufficient synchronization that could lead to belt misalignment or material spillage, thus reducing operational risks.

[0044] Among them, a conical groove 2101 is provided at the position where the rectangular telescopic rod 21 is movably sleeved with the extrusion moving block 23, and a conical extrusion head 2301 is fixedly connected to the side of the extrusion moving block 23 near the rectangular telescopic rod 21.

[0045] In this embodiment, the conical groove 2101 and the conical extrusion head 2301 facilitate the extension and retraction of the conical extrusion head 2301 when the rectangular telescopic rod 21 moves, thereby causing the extrusion moving block 23 to drive the adjusting rod 16 and the limiting collar 18 to move.

[0046] Among them, the synchronous switch 7 includes a threaded rod 701, one end of which is fixedly connected to a limit slide plate 702 inside the connecting block 9, a rotary valve 703 is fixedly connected to the surface of the threaded rod 701 near the top, and a compression piston rod 704 is movably sleeved inside the threaded rod 701.

[0047] In this embodiment, the synchronous switch 7 helps to prevent the internal compression piston rod 704 from starting when it is energized during descent, thereby increasing the safety of its actual operation.

[0048] Working principle of the invention:

[0049] First, when starting the dual-drive conveyor, hold the rotary valve 703 on the surface of the threaded rod 701 and rotate it. This causes the rotary valve 703 to drive the threaded rod 701 and the limiting slide 702 to rotate. At this time, the rotation of the threaded rod 701 pushes the limiting slide 702 and the connecting block 9 to descend. Then, the bottom of the squeeze piston rod 704 does not follow the threaded rod 701 to descend because it is restricted by the telescopic rod 20. Then, the descent of the connecting block 9 drives the fixing block 11 and the power-connecting block 12 to move closer to the middle of the first line connector 14 and the second line connector 15. Then, the first line connector 14 and the second line connector 15 are connected and energized through the power-connecting block 12. At this time, the conveyor motor 5 on the top of the motor mounting plate 4 is energized and starts to run.

[0050] Then, when the conveyor motor 5 is powered on, it drives the rotating shaft 17 to rotate. When the rotating shaft 17 rotates, the limiting collar 18 on its surface is restricted by the adjusting rod 16 and does not rotate with the rotating shaft 17. Then, the rotating shaft 17 rotates away from the surface of the limiting collar 18 and inside the connector 1003. Then, the telescopic docking plate 19 inside the rotating shaft 17 cannot extend or retract with the centrifugal force due to the restriction of the limiting collar 18. At this time, the rotating shaft 17 idles inside the connector 1003 and cannot drive the conveyor roller 10 to rotate. Then, when the conveyor motor 5 starts and is synchronized by the idle rotation, the extrusion piston rod 704 is pressed down, so that the extrusion piston rod 704 presses against the telescopic rod 20 and then presses against the telescopic rod 20. The telescopic rod 20 is squeezed into the inside of the conveying start box 8. Then, by pressing the extrusion ball inside the conveying start box 8, the extrusion ball at one end of the rectangular telescopic rod 21 is pushed. At this time, the rectangular telescopic rod 21 separates to both sides. Then, the rectangular telescopic rod 21 pushes the return spring 22 at the other end to retract. At the same time, the movement of the rectangular telescopic rod 21 causes the conical extrusion head 2301 of the extrusion moving block 23 inside the conical groove 2101 to be extruded out of the conical groove 2101. Then, the extrusion moving block 23 moves to one side to extrude the micro spring 24 and drive the adjusting rod 16 and the limiting collar 18 fixed at the other end of the adjusting rod 16 to move to one side.

[0051] Then, the movement of the limiting collar 18 releases the restriction of the telescopic docking plate 19 inside the rotating shaft 17. At this time, the centrifugal force generated by the rotation of the rotating shaft 17 drives the telescopic docking plate 19 and the limiting post 1902 to pull the limiting spring 1904 inside the fixed sleeve 1903 to slide inside the rectangular groove 1701. At this time, the telescopic docking plate 19 meshes with the rectangular docking groove 1004 inside the connector 1003 and drives the conveying roller 10 to rotate. Then, the rotation of the conveying roller 10 drives the conveyor belt 2 to transport.

[0052] Then, when the equipment needs to be shut down, the synchronous switch 7 is rotated in the reverse direction, causing the synchronous switch 7 to lift the connecting block 9, thereby causing the power connection block 12 to disengage from the middle position adjacent to the first line connector 14 and the second line connector 15. At this time, the conveyor motor 5 stops rotating due to power failure, causing the rotating shaft 17 to rotate. This causes the telescopic docking plate 19 to be pulled back into the rectangular groove 1701 by the limiting spring 1904. Then, the miniature spring 24 pushes the squeezing moving block 23 to drive the adjusting rod 16 and the limiting collar 18 to reset.
