Description

Technical Field

[0001] This invention relates to the field of material unloading devices, specifically a loading and unloading device for a smart port. Background Technology

[0002] The loading and unloading system in a smart port is one of the core pieces of equipment for achieving efficient, precise, and automated loading operations. Currently, the loading and unloading systems equipped in ports are mainly used for loading coal onto trains. Most intelligent loading and unloading systems consist of core components such as intelligent identification and control systems, automated actuators, and metering systems.

[0003] During the loading process, the train cars pass under the unloading device one by one at a relatively slow speed. At this time, the intelligent identification system within the unloading device accurately identifies the train cars below and quickly transmits the identification signal to the control system. Upon receiving the signal, the control system immediately issues a command to drive the automated actuators. The automated actuators then initiate the coal loading process, orderly guiding the coal to be loaded into the metering system. Subsequently, the metering system monitors the weight of the coal in real time. When the weight of the coal in the system reaches the pre-set loading capacity for a single car, the metering system triggers the unloading action, precisely pouring the coal from the system into the train cars. Simultaneously, the control system intelligently adjusts the gate opening and closing status according to the train's real-time speed, ensuring that the coal loading capacity in each car is approximately the same, achieving efficient and precise loading operations.

[0004] However, in the above process, due to the gaps between each train car, the discharge device closes the gate when it is about to reach the gap between the cars to prevent coal from falling outside the car; it only opens the gate when it reaches the next car to allow coal to fall into the car. That is, the discharge device does not discharge when it is near the front and rear ends of each car, resulting in a lower coal accumulation height at the front and rear ends of each car compared to the middle, thus reducing the loading efficiency of the car. As the number of cars increases, the weight of coal transported by the train decreases, potentially requiring multiple round trips and further impacting transportation efficiency. Therefore, we propose a smart port loading and unloading device to effectively address these drawbacks. Summary of the Invention

[0005] The purpose of this invention is to provide a loading and unloading device for a smart port, which solves the problems mentioned in the background art.

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figure 1 In the current coal loading process on trains, due to the gaps between train cars, to prevent material from spilling onto the outside of the cars and wasting resources, the gates in the unloading device are usually closed when they approach the gap between the cars. They are only reopened to allow material to fall when another car moves beneath the unloading device. This unloading method results in less material loaded at both ends of the car, leading to a situation where the material accumulation height at the ends of the car is lower than that in the middle. This not only affects the overall loading weight but also increases the number of round trips the train makes, impacting the efficiency of material transportation.

[0037] To address the above problems, the present invention proposes the following technical solution:

[0038] Please see Figure 2 - Figure 11 A loading and unloading device for a smart port includes a buffer section 1, which is located at the top of the device. The buffer section 1 has an internal hollow structure and openings at both the top and bottom. A double gate 2 is fixedly provided at the bottom of the buffer section 1.

[0039] The buffer section 1 includes a buffer bin 101 and a buffer chute 102. The buffer chute 102 is fixedly connected to the bottom of the buffer bin 101, and the double gate 2 is fixedly connected to the bottom opening of the buffer chute 102 by bolts. Most existing loading and unloading devices use jaw gates, which consist of four arc-shaped gate plates. The gate is opened and closed by rotating these four arc-shaped gate plates. The double gate 2, however, consists of two horizontal gate plates, and servo cylinders are installed on both sides of the gate. A linear displacement sensor is built into the gate, which not only precisely controls the opening and closing degree of the gate, but also allows the double gate 2 to open more than the maximum opening degree of the jaw gate, thus increasing the unloading speed.

[0040] Furthermore, the gate plate support for the opposing gate 2 is made of ultra-high sliding blocks, which possess excellent properties such as wear resistance, impact resistance, chemical corrosion resistance, self-lubrication, low coefficient of friction, light weight, and aging resistance. The lubrication-free function of the ultra-high sliding blocks eliminates the need for manual lubrication, and their long service life reduces the frequency of replacement, saving labor and materials.

[0041] Furthermore, a weighing unit 3 is fixedly connected to the bottom of the double gate 2. The weighing unit 3 has an internal hollow structure and openings at both the top and bottom. The weighing unit 3 is used to calculate the weight of the discharged material. The weighing unit 3 includes a weighing chute 301 and a weighing bin 302. The weighing chute 301 is fixedly connected to the bottom of the double gate 2 via a connecting flange, and the weighing bin 302 is fixedly connected to the bottom of the weighing chute 301. When the double gate 2 is opened, the weighing unit 3 and the buffer unit 1 are internally connected. A discharge gate 4 is fixedly provided at the bottom of the weighing unit 3. The discharge gate 4 is fixedly connected to the bottom opening of the weighing bin 302 via a gate flange 401. The discharge gate 4 is of the same type as the double gate 2, and also consists of two relatively sliding gate plates, a servo cylinder, and a linear displacement sensor.

[0042] An anti-blocking mechanism 5 is also provided on the unloading gate 4. The anti-blocking mechanism 5 is used to drive the weighing part 3 to vibrate so that the material on the inner wall of the weighing part 3 falls off.

[0043] Specifically, the anti-clogging mechanism 5 includes a fixed chute 501 fixedly connected to the bottom of the discharge gate 4. The fixed chute 501 is connected to the discharge gate 4 via a connecting flange. Several vibrators 502 are installed on the outer wall of the fixed chute 501. The fixed chute 501 is made of 12mm carbon steel plate and lined with extra-high plates to prevent material from sticking to the inner wall of the fixed chute 501, accelerate the discharge speed, and prevent clogging accidents. At the same time, the vibration of the vibrators 502 can cause the fixed chute 501 and the bottom discharge port of the weighing unit 3 to vibrate, further allowing the material inside to fall smoothly. The anti-clogging mechanism 5 also includes a vent pipe 503 fixedly connected to the gate flange 401. The top end of the vent pipe 503 is connected to the interior of the weighing unit 3 and is used to connect to an external air source to balance the air pressure inside and outside the weighing unit 3. During loading, materials (such as coal and ore) are rapidly loaded into the truck through the weighing hopper 302, which may cause negative pressure to form inside the equipment (air is carried away by the material) or local pressure increases (such as material accumulation inside the weighing hopper 302). At this time, the vent pipe connects to an external air source and the weighing hopper 302 to balance the internal and external air pressure, preventing deformation or damage to the equipment due to pressure differences. It also prevents material from clogging the discharge port, avoiding coal dust explosions and improving safety.

[0044] Furthermore, a telescopic chute assembly 6 is fixedly connected to the bottom of the anti-clogging mechanism 5. The telescopic chute assembly 6 includes a transition chute 601 fixedly connected to the bottom of the anti-clogging mechanism 5. The transition chute 601 is connected to the fixed chute 501 via a connecting flange. The transition chute 601 is arc-shaped and has an opening at the bottom. A swing chute 602 is rotatably mounted on the transition chute 601. The swing chute 602 is arc-shaped and is semi-enclosed on the outside of the bottom opening of the transition chute 601. Figure 5As shown, the transition chute 601 and the swing chute 602 have the same center, and the swing chute 602 rotates around the center at the bottom of the transition chute 601; the outside of the transition chute 601 is also provided with a first drive assembly for driving the swing chute 602 to swing.

[0045] In this embodiment, the first driving component is a hydraulic winch, the movable end of which is connected to the outside of the swing chute 602 to control the swing chute 602 to swing back and forth.

[0046] Furthermore, the bottom of the swing chute 602 is fixedly connected to the upper chute 603, and the outer side of the upper chute 603 is slidably fitted with the middle chute 604 along the height direction of the upper chute 603. The telescopic chute assembly 6 also includes a second drive assembly for driving the middle chute 604 to slide relative to the upper chute 603. In this application, the second drive assembly is a servo cylinder. The fixed end of the servo cylinder is connected to the outer side of the upper chute 603, and the movable end of the servo cylinder is connected to the outer side of the middle chute 604 to control the middle chute 604 to slide outside the upper chute 603. The upper chute 603 base plate is made of 12mm Q235 steel plate, lined with 6mm 304 stainless steel, and the outer periphery is supported and guided by precision-machined 80mm stainless steel square tubes; the middle chute 604 base plate is made of 12mm Q235 steel plate, lined with 6mm 304 stainless steel, and extra-high plates are installed at the four corners and the upper part of the four sides as slide rails.

[0047] And, as Figure 5 As shown, a lower chute is fixedly connected to the bottom of the middle chute 604. The base plate of the lower chute is made of 12mm Q235 steel plate and lined with 6mm 304 stainless steel. The lower opening is trumpet-shaped to facilitate loading, and the front end uses a 35mm steel plate as a counterweight to prevent the coal from arching during loading.

[0048] Furthermore, the telescopic chute assembly 6 is rotatably equipped with a deflector plate 7, a first variable plate 701, and a second variable plate 702.

[0049] Specifically, the widths of the deflector plate 7, the first variable plate 701, and the second variable plate 702 are all adapted to the inner width of the middle section chute 604. The deflector plate 7, the first variable plate 701, and the second variable plate 702 are rotatably connected to the inner bottom of the middle section chute 604 via the first rotating shaft 703, the second rotating shaft 704, and the third rotating shaft 705, respectively. Figure 7 As shown, the deflector plate 7 can rotate around the first rotating shaft 703 so that one side abuts against the inner wall of the intermediate chute 604, causing the material in the intermediate chute 604 to fall along the surface of the deflector plate 7, thereby changing the discharge direction of the device. The rotation of the first variable plate 701 and the second variable plate 702 can change the size of the opening at the bottom of the intermediate chute 604, thereby changing the discharge flow rate of the device.

[0050] It is worth mentioning that limiting components 9 are provided on both the left and right sides of the intermediate chute 604. The limiting components 9 are used to abut against the top surface of the deflector plate 7 to limit the deflector plate 7. The limiting components 9 include a limiting cover 901 fixedly connected to the outer wall of the intermediate chute 604, and the interior of the limiting cover 901 is connected to the inner cavity of the intermediate chute 604. A limiting rod 902 is elastically connected to the limiting cover 901 along its width direction by a spring 904. In its natural state, the spring 904 is in a compressed state. One end of the limiting rod 902 can slide into the inner cavity of the intermediate chute 604, and when the top of the deflector plate 7 abuts against the inner wall of the intermediate chute 604, the bottom surface of the limiting rod 902 can abut against the top surface of the deflector plate 7 to prevent the deflector plate 7 from flipping upward. An electromagnet 903 is fixedly installed on the inner wall of the limiting cover 901 away from the middle section chute 604. A magnetic block is fixedly installed on the side of the limiting rod 902 facing the electromagnet 903. Therefore, when the electromagnet 903 is energized, it can attract the magnetic block, thereby driving the limiting rod 902 to slide out of the interior of the middle section chute 604, so that the deflector plate 7 can be flipped.

[0051] Furthermore, it should be noted that the electromagnet 903 is electrically connected to an external power source, which is a DC battery with a voltage of 12V. Whenever the deflector plate 7 needs to be rotated, the electromagnet 903 is first activated to retract the limit rod 902 into the limit cover 901; after the deflector plate 7 has finished rotating, the power is disconnected to allow the limit rod 902 to pop out again.

[0052] In this application, the telescopic chute assembly 6 is provided with a drive mechanism 8. The drive mechanism 8 is used to drive the deflector plate 7 to rotate to change the discharge direction. The drive mechanism 8 is also used to drive the first variable plate 701 and the second variable plate 702 to rotate to change the discharge flow rate.

[0053] The drive mechanism 8 is described in detail below:

[0054] like Figure 6 As shown, both ends of the first rotating shaft 703, the second rotating shaft 704 and the third rotating shaft 705 extend to the outside of the middle section chute 604. The drive mechanism 8 includes two first gears 801, two second gears 802 and two third gears 803. The two first gears 801 are respectively fixedly mounted on both ends of the first rotating shaft 703, the two second gears 802 are respectively fixedly mounted on both ends of the second rotating shaft 704, and the two third gears 803 are respectively fixedly mounted on both ends of the third rotating shaft 705.

[0055] The drive mechanism 8 also includes two mounting rods 804 fixedly connected to the outer wall of the upper chute 603. The two mounting rods 804 are symmetrically located on the front and rear sides of the upper chute 603. The bottom of each mounting rod 804 is vertically fixed with a first rack 805, a second rack 806, and a third rack 807. The first rack 805 meshes with the first gear 801, the second rack 806 meshes with the second gear 802, and the third rack 807 meshes with the third gear 803. When the middle chute 604 slides on the outside of the upper chute 603, the first rack 805, the second rack 806, and the third rack 807 will drive the first gear 801, the second gear 802, and the third gear 803 to rotate, thereby causing the deflector plate 7, the first variable plate 701, and the second variable plate 702 to flip.

[0056] It is worth mentioning that the second gear 802 and the third gear 803 have the same diameter, and the tooth spacing of the second rack 806 and the third rack 807 is equal. Therefore, the rotation angles of the second gear 802 and the third gear 803 are equal. The diameter of the first gear 801 is smaller than the diameter of the second gear 802. Therefore, the flip angle of the deflector plate 7 is greater than the flip angles of the first variable plate 701 and the second variable plate 702. The second rack 806 and the third rack 807 mesh on the same side of the second gear 802 and the third gear 803, respectively, while the first rack 805 meshes on the other side of the first gear 801. Therefore, the rotation directions of the second gear 802 and the third gear 803 are the same, while the rotation direction of the first gear 801 is opposite to that of the second gear 802 and the third gear 803.

[0057] The working principle and usage process of this invention: When the material discharge device just reaches one side of the carriage, the upper chute 603 and the middle chute 604 tilt, and at the same time, the middle chute 604 moves upward, shortening the overall length of the upper chute 603 and the middle chute 604. At this time, the orientation of the deflector plate 7, the first variable plate 701, and the second variable plate 702 is as follows... Figure 9 As shown, the material falls along the surface of the deflector plate 7 into the right side of the carriage, and the second deflector plate 702 reduces the opening size at the bottom of the intermediate chute 604 to prevent excessive material flow from spilling onto the outside of the carriage. Furthermore, during this process, the front wall of the carriage gradually moves away from the discharge device, thus requiring the intermediate chute 604 to move upwards to increase the material's landing point, thereby increasing the horizontal falling distance and allowing the material to better fill the front area of ​​the carriage.

[0058] When the material discharge device is located above the middle of the car body, the upper chute 603 and the middle chute 604 return to the vertical position, and the overall length of the middle chute 604 and the upper chute 603 returns to the normal length. At this time, the deflector plate 7 is also in a vertical position, and the material can fall vertically into the car body.

[0059] When the discharge device moves to the left side of the car body, the upper chute 603 and the middle chute 604 tilt again, and the middle chute 604 moves downward, extending the overall length of the upper chute 603 and the middle chute 604. At this time, the orientation of the deflector plate 7, the first variable plate 701, and the second variable plate 702 is as follows: Figure 8 As shown, the material will fall along the surface of the deflector plate 7 into the left side of the carriage. During this process, the rear side wall of the carriage gradually approaches the discharge device, so the middle chute 604 needs to be moved downward to lower the landing point of the material, thereby shortening the horizontal falling distance of the material and preventing the material from spilling outside the carriage.

[0060] In summary, the embodiments of this application combine multiple unloading methods to ensure that materials are more evenly filled throughout the interior of the carriage, thereby improving the loading utilization rate of the carriage.
