Description

Technical Field

[0001] The present invention relates to the technical field of discharging devices, and particularly to a loading and discharging device for trucks in a smart port. Background Technique

[0002] The loading and discharging device for trucks in a smart port is one of the core devices for the smart port to achieve efficient, accurate, and automated truck loading operations. At present, the loading and discharging devices equipped in ports are mainly used for coal loading operations on coal-carrying trains. Most intelligent loading and discharging devices are composed of core components such as intelligent recognition and control systems, automated actuators, and metering systems.

[0003] During the truck loading operation, the truck compartments will pass sequentially under the discharging device at a relatively slow speed. At this time, the intelligent recognition system in the discharging device will accurately identify the truck compartments located below it and quickly transmit the recognition signal to the control system. After receiving the signal, the control system immediately issues an instruction to drive the automated actuator to start operating. The automated actuator then initiates the coal loading process, orderly guiding the coal to be loaded into the metering system. Subsequently, the metering system will monitor the weight of the coal in real time. When the weight of the coal in the system reaches the pre-set loading amount for a single compartment, the metering system will trigger the discharging action, accurately pouring the coal in the system into the truck compartment. At the same time, the control system will intelligently adjust the gate opening and closing state according to the real-time driving speed of the truck, so as to ensure that the loading amount of coal in each compartment is roughly the same, achieving efficient and accurate loading operations.

[0004] However, in the above process, since there are gaps between each truck compartment, when the discharging device is about to reach the gap between the compartments, it will close the gate to prevent the coal from falling outside the compartment; and when it reaches above the next compartment, it will open the gate to let the coal fall into the compartment. That is, when the discharging device is near the front and rear ends of each compartment, no discharging operation will be performed, which will result in the height of the coal accumulation at the front and rear ends of each compartment being lower than the height of the coal accumulation in the middle of the compartment, thus reducing the loading efficiency of the compartment. As the number of compartments increases, the weight of the coal transported by the truck will also decrease, so the truck may need to make multiple round trips, which will affect the transportation efficiency. For this reason, we have proposed a loading and discharging device for trucks in a smart port to well solve the above drawbacks. Summary of the Invention

Detailed implementation manners

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figure 1 , in the existing process of loading coal onto trains, due to the certain gaps between train carriages, in order to avoid the waste of resources caused by materials spilling outside the carriages, the gates in the discharging device usually close when approaching the gaps between the carriages, and will not be opened again until another carriage moves under the discharging device to let the materials fall. Such a discharging method will result in less materials loaded at both ends of the carriage, thus forming a situation where the stacking height of materials at both ends of the carriage is lower than that in the middle of the carriage. This will not only affect the overall loading weight but also increase the number of round trips of the train, affecting the transportation efficiency of the materials.

[0037] To solve the above problems, the present invention proposes the following technical solutions:

[0038] Please refer to Figure 2 - Figure 11 , a loading and discharging device for a smart port, including a buffer part 1. The buffer part 1 is located at the top of the device. The buffer part 1 has a hollow structure inside and openings at both the upper and lower ends. A split gate 2 is fixedly provided at the bottom of the buffer part 1.

[0039] Among them, the buffer part 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. The split gate 2 is fixedly connected to the bottom opening of the buffer chute 102 by bolts. Most of the existing loading and discharging devices use a jaw gate, which is composed of four arc-shaped gate plates, and the opening and closing of the gate are realized by the rotation of the four arc-shaped gate plates. The split gate 2 is composed of two horizontal gate plates, and servo cylinders are arranged on both sides of the gate, and a linear displacement sensor is arranged inside the gate. It can not only accurately control the opening degree of the gate, but also the maximum opening degree of the split gate 2 is greater than that of the jaw gate. Therefore, the discharging speed will be increased.

[0040] More optimally, the gate plate support of the split gate 2 is made of ultra-high sliders. The ultra-high sliders have excellent properties such as wear resistance, impact resistance, chemical corrosion resistance, self-lubrication, small friction coefficient, light weight, and anti-aging. The lubrication-free function of the ultra-high sliders eliminates the current manual lubrication, and the high service life reduces the replacement frequency, which can save labor and materials.

[0041] Furthermore, a weighing section 3 is fixedly connected to the bottom of the split gate 2. The weighing section 3 has a hollow structure inside and openings at both the upper and lower ends. The weighing section 3 is used to calculate the discharging weight. The weighing section 3 includes a weighing chute 301 and a weighing bin 302. The weighing chute 301 is fixedly connected to the bottom of the split gate 2 through a connecting flange. The weighing bin 302 is fixedly connected to the bottom of the weighing chute 301. When the split gate 2 is opened, the inside of the weighing section 3 is connected to the inside of the buffer section 1. A discharging gate 4 is fixedly provided at the bottom of the weighing section 3. The discharging gate 4 is fixedly connected to the opening at the bottom of the weighing bin 302 through a gate flange 401. Among them, the discharging gate 4 is of the same type as the split gate 2, and is also composed of two relatively sliding gate plates, a servo oil cylinder and a linear displacement sensor.

[0042] An anti-blocking mechanism 5 is further provided on the discharging gate 4. The anti-blocking mechanism 5 is used to drive the weighing section 3 to vibrate so that the materials on the inner wall of the weighing section 3 fall off.

[0043] Specifically, the anti-blocking mechanism 5 includes a fixed chute 501 fixedly connected to the bottom of the discharging gate 4. The fixed chute 501 is connected to the discharging gate 4 through a connecting flange. A plurality of vibrators 502 are provided on the outer side wall of the fixed chute 501. The fixed chute 501 is made of a t12mm carbon steel plate, and its inner lining is a ultra-high plate, which can prevent the inner wall of the fixed chute 501 from sticking materials, accelerate the discharging speed, and prevent blockage accidents. At the same time, the vibration of the vibrator 502 can make the bottom discharging port of the fixed chute 501 and the weighing section 3 vibrate, further enabling the internal materials to fall smoothly. The anti-blocking mechanism 5 further includes a ventilation pipe 503 fixedly connected to the gate flange 401. The top end of the ventilation pipe 503 communicates with the inside of the weighing section 3. The ventilation pipe 503 is used to connect to an external air source to balance the air pressure inside and outside the weighing section 3. During the loading process, materials (such as coal, ore, etc.) are quickly loaded into the carriage through the weighing bin 302, which may cause a negative pressure inside the device (air is carried away by the materials) or a local pressure increase (such as material accumulation in the weighing bin 302). At this time, the ventilation pipe connects the external air source and the weighing bin 302 to achieve the effect of balancing the internal and external air pressures, avoiding deformation or damage of the equipment due to the pressure difference. It can also prevent materials from blocking at the discharging port, avoid dust explosion of pulverized coal, and improve safety.

[0044] Furthermore, a telescopic chute assembly 6 is fixedly connected to the bottom of the anti-blocking mechanism 5. The telescopic chute assembly 6 includes a transition chute 601 fixedly connected to the bottom of the anti-blocking mechanism 5. The transition chute 601 is connected to the fixed chute 501 through a connecting flange. The transition chute 601 is arc-shaped and has an opening at the bottom. A swing chute 602 is rotatably provided on the transition chute 601. The swing chute 602 is arc-shaped. The swing chute 602 is arranged in a semi-surrounding manner outside the opening at the bottom of the transition chute 601, as Figure 5As shown, the transition chute 601 and the swing chute 602 have the same center of circle, and the swing chute 602 rotates around the center at the bottom of the transition chute 601; a first driving assembly for driving the swing chute 602 to swing is further provided outside the transition chute 601.

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

[0046] Furthermore, an upper chute 603 is fixedly connected to the bottom of the swing chute 602. A middle chute 604 is slidably sleeved on the outside of the upper chute 603 along the height direction of the upper chute 603. The telescopic chute assembly 6 further includes a second driving assembly for driving the middle chute 604 to slide relative to the upper chute 603. In this application, the second driving assembly is a servo oil cylinder. The fixed end of the servo oil cylinder is connected to the outside of the upper chute 603, and the movable end of the servo oil cylinder is connected to the outside of the middle chute 604 to control the middle chute 604 to slide on the outside of the upper chute 603. Among them, the upper chute 603 substrate is made of 12mm Q235 steel plate, lined with 6mm 304 stainless steel, and the periphery is supported and guided by a precision-machined 80mm stainless steel square tube; the middle chute 604 substrate is made of 12mm Q235 steel plate, lined with 6mm 304 stainless steel, and ultra-high plates are installed at the four corners and the upper parts of the four sides as slide rails.

[0047] And, as Figure 5 shown, a lower chute is fixedly connected to the bottom of the middle chute 604. The lower chute substrate is made of 12mm Q235 steel plate, lined with 6mm 304 stainless steel. The lower opening is trumpet-shaped for easy loading. The front end is weighted with a 35mm steel plate to prevent arching when loading coal.

[0048] Furthermore, a deflector plate 7, a first variable plate 701 and a second variable plate 702 are rotatably provided inside the telescopic chute assembly 6.

[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 cavity width of the middle chute 604. The deflector plate 7, the first variable plate 701 and the second variable plate 702 are respectively rotatably connected to the inner bottom of the middle chute 604 through a first rotating shaft 703, a second rotating shaft 704 and a third rotating shaft 705. As Figure 7 shown, the deflector plate 7 can rotate around the first rotating shaft 703 to make one side abut against the inner side wall of the middle chute 604, so that the material in the middle chute 604 will fall along the surface of the deflector plate 7, thereby changing the discharging direction of the device. The rotation of the first variable plate 701 and the second variable plate 702 can change the opening size at the bottom of the middle chute 604, thereby changing the discharging flow rate of the device.

[0050] It is worth mentioning that limiting components 9 are provided on both the left and right side surfaces of the middle chute 604. The limiting components 9 are used to abut against the top surface of the deflecting plate 7 to limit the deflecting plate 7. Among them, the limiting component 9 includes a limiting cover 901 fixedly connected to the outer side wall of the middle chute 604. The inside of the limiting cover 901 is communicated with the inner cavity of the middle chute 604. A limiting rod 902 is elastically connected in the limiting cover 901 along its own width direction through a spring 904. In the 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 middle chute 604, and when the top of the deflecting plate 7 abuts against the inner side wall of the middle chute 604, the bottom surface of the limiting rod 902 can abut against the top surface of the deflecting plate 7 to prevent the deflecting plate 7 from flipping upwards. An electromagnet 903 is fixedly provided on the inner wall of the limiting cover 901 far from the middle chute 604. A magnetic block is fixedly provided on the surface of the limiting rod 902 facing the electromagnet 903. Therefore, when the electromagnet 903 is powered on, the magnetic block can be adsorbed, thereby driving the limiting rod 902 to slide out of the inside of the middle chute 604, so that the deflecting plate 7 can be flipped.

[0051] Moreover, it should be added that the electromagnet 903 is electrically connected to an external power supply. The external power supply uses a DC battery with a voltage of 12V. Whenever it is necessary to rotate the deflecting plate 7, the electromagnet 903 is first turned on to retract the limiting rod 902 into the limiting cover 901. After the deflecting plate 7 rotates, the power supply is then disconnected to make the limiting rod 902 pop out again.

[0052] In the present application, a driving mechanism 8 is provided on the telescopic chute assembly 6. The driving mechanism 8 is used to drive the deflecting plate 7 to rotate to change the discharging direction, and the driving mechanism 8 is also used to drive the first variable plate 701 and the second variable plate 702 to rotate to change the discharging flow rate.

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

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

[0055] The driving mechanism 8 further includes two mounting rods 804 fixedly connected to the outer side 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. At the bottom of the two mounting rods 804, a first rack 805, a second rack 806, and a third rack 807 are fixedly provided vertically. 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 outside the upper chute 603, the first rack 805, the second rack 806, and the third rack 807 will respectively drive the first gear 801, the second gear 802, and the third gear 803 to rotate, thereby driving the deflector 7, the first variable plate 701, and the second variable plate 702 to flip.

[0056] It is worth mentioning that the diameters of the second gear 802 and the third gear 803 are equal, and the tooth pitch 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 flipping angle of the deflector 7 is greater than the flipping angles of the first variable plate 701 and the second variable plate 702. The second rack 806 and the third rack 807 are respectively meshed on the same side of the second gear 802 and the third gear 803, and the first rack 805 is meshed 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 the present invention: When the feeding device just reaches one side of the carriage, the upper chute 603 and the middle chute 604 are inclined, 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 orientations of the deflector 7, the first variable plate 701, and the second variable plate 702 are as Figure 9 shown. The material will fall onto the right side of the carriage along the surface of the deflector 7, and the second variable plate 702 will reduce the opening size at the bottom of the middle chute 604 to prevent the material from spilling outside the carriage due to excessive feeding flow. Moreover, during this process, the front side wall of the carriage gradually moves away from the feeding device. Therefore, it is necessary to move the middle chute 604 upward to increase the landing point of the material, thereby increasing the horizontal landing distance of the material and enabling the material to better fill the front side area of the carriage.

[0058] When the feeding device is above the middle of the carriage, the upper chute 603 and the middle chute 604 return to the vertical state, and at the same time the overall length of the middle chute 604 and the upper chute 603 returns to the normal length. At this time, the deflector 7 is also in the vertical state, and the material can fall vertically into the carriage.

[0059] When the feeding device moves to the left side of the carriage, the upper chute 603 and the middle chute 604 are tilted again, and the middle chute 604 moves downward to extend the overall length of the upper chute 603 and the middle chute 604. At this time, the orientations of the deflector plate 7, the first variable plate 701, and the second variable plate 702 are as Figure 8 shown, and the material will fall onto the left side of the carriage along the surface of the deflector plate 7. Moreover, during this process, the rear side wall of the carriage gradually approaches the feeding device. Therefore, it is necessary to move the middle chute 604 downward to lower the dropping point of the material, thereby shortening the horizontal dropping distance of the material and preventing the material from spilling outside the carriage.

[0060] In summary, through the combined use of multiple discharging methods in the embodiments of the present application, the material can be more evenly filled in various parts inside the carriage, so as to improve the loading utilization rate of the carriage.

[0061] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or sequence between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the element.

[0062] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
