TECHNICAL FIELD
[0001] The utility model belongs to bulk cargo export loading technology field, more particularly, relate to a big water level difference bulk cargo wharf grading loading system. BACKGROUND
[0002] At present, the bulk cargo export loading operation of the bulk cargo wharf with big water level difference, especially the wharf located in the mountainous river basin, is usually restricted by the factors such as narrow river basin, large water level amplitude, steep slope and insufficient longitudinal depth of land area, and there is no good bulk cargo export process solution. The wharf loading and unloading process systems implemented and applied can be mainly divided into two categories: wharf wall type wharf export scheme and slope wharf export scheme. Due to the restriction of the above objective factors, both schemes have some deficiencies and problems difficult to solve properly in the actual production operation of the wharf.
[0003] Among them, the wharf wall type loading process usually equips the loading machine on the wharf platform above the high water level, and the material is transported to the loading machine through the belt conveyor. The loading mechanism adopts a mobile type or a rotary type, and the material is loaded into the export cabin through the arm support belt. In the loading operation, especially in the low water level operation, the direct material falling height reaches about 20m-30m, the falling difference of the material from the loading machine to the cabin is too large, which causes serious material damage, large impact damage to the ship structure, and a large amount of dust difficult to control, resulting in poor environmental protection. The slope wharf scheme mainly solves the problem of large material loading falling difference. The scheme is equipped with a berthing barge in front of the wharf, and a circular arc track loading machine is usually equipped above the barge. With the change of water level, the barge is lifted and moved along the overhead ramp at the same time. The export belt car system is arranged above the overhead ramp to realize the connection of the ship-shore conveying system. Due to the inclination angle limitation of the belt conveyor, the slope of the overhead ramp is generally required to be not steeper than 1:4. In the case of large water level difference, the length of the overhead ramp required is relatively long, and the water conservancy structure investment is relatively large. The overhead ramp belt car must be synchronously dragged and moved with the barge to ensure that it is not flooded and the conveying is stable, which leads to a relatively complex whole process system. At the same time, the long overhead ramp needs to extend far into the river, which affects the safety of ship navigation and has a great influence on the river flood discharge.
[0004] Therefore, the technical personnel in the field urgently need to provide a bulk cargo loading system capable of realizing different grading, improve and improve the existing bulk cargo export wharf process technology, and meet the development requirements of green, safe and innovation of water transportation industry.

[0045] Specifically, the embodiment describes in detail a large water level difference bulk cargo wharf grading loading system, which aims to solve many problems of traditional wharfs when facing large water level differences. The system mainly comprises a bank-side water engineering platform module and a water-side pontoon 14 platform module, and forms a multi-level material falling height difference to realize efficient and stable loading operation.
[0046] The bank-side water engineering platform module is the core part of the system, comprising a quay wall platform 1, a first boom conveyor 2, a rear material receiving conveyor 4, a driving mechanism 5 and a first buffer connection device 8. The quay wall platform 1 is fixed to the structure building on the bank side, providing stable support for the entire system. The first boom conveyor 2 is composed of a portal 3 and a luffing boom structure, the portal 3 being fixed to the quay wall platform 1, one end of the luffing boom structure being movably connected to the bottom of the portal 3, and the other end of the luffing boom structure being connected to the water-side pontoon 14 platform module, responsible for conveying goods from the bank side to the water side. The rear material receiving conveyor 4 is located at the middle of the portal 3 and directly above the luffing boom structure, for receiving goods from the rear. The driving mechanism 5 is arranged at the bottom of the portal 3, driving the luffing boom structure to rotate around the connection point with the portal 3, to adapt to different loading requirements. The first buffer connection device 8 is arranged at the water-side pontoon 14 platform module and directly below the other end of the luffing boom structure, for buffering and connecting goods.
[0047] The water side pontoon 14 platform module includes a bulk carrier 13 and a pontoon 14 arranged side by side. The pontoon 14 is provided with a circular track ship loader 11, one end of which is connected to a receiving hopper 9 through one end of a belt conveyor 10, and the receiving hopper 9 is connected to a first receiving buffer device 8 for receiving the cargo delivered from the shore side. The other end of the belt conveyor 10 is located above the bulk carrier 13 and is connected through a second receiving buffer device 12 to ensure smooth transfer of the cargo from the pontoon 14 to the bulk carrier 13.
[0048] In actual operation, the cargo is first delivered by the rear material delivery conveyor 4 to the luffing boom structure of the first boom conveyor 2. The drive mechanism 5 adjusts the rotation of the luffing boom structure according to the water level difference and the loading requirements, so that the cargo can be smoothly delivered to the water side pontoon 14 platform module. In the water side pontoon 14 platform module, the cargo is finally smoothly loaded onto the bulk carrier 13 through the cooperation of the circular track ship loader 11 and the belt conveyor 10. The second receiving buffer device 12 plays a key role in this process, ensuring the stability and safety of the cargo during the transfer process.
[0049] The entire system takes into account the challenges of large water level differences, and through the setting of multi-level material drop height differences, as well as flexible boom conveyors and buffer devices, efficient and stable loading operations are achieved. This design not only improves the loading efficiency, but also reduces the operation risk, and is suitable for bulk cargo terminals in various large water level difference environments.
[0050] As shown in Figures 1-3 LWL: low-water-level design low water level; MWL: middle-water-level middle water level; HWL: high-water-level design high water level; H1: first-level material drop height difference; H2: second-level material drop height difference; H3: third-level material drop height difference; H4: fourth-level material drop height difference.
[0051] Preferably, the drive mechanism 5 includes a winch, the rope of which is connected to the luffing boom structure through the top of the portal frame 3 to form a tensile constraint on the luffing boom, and can be adjusted in real time according to the actual material drop transport height requirement.
[0052] Preferably, the loading system further comprises a luffing boom conveyor 7 arranged on the luffing boom structure, one end of the luffing boom conveyor 7 being connected to the rear material delivery conveyor 4, and the other end of the luffing boom conveyor 7 being connected to the second receiving buffer device 12.
[0053] In the specific embodiments of the present patent, we have optimized the design of the first buffer connection device 8 and the second buffer connection device to improve the efficiency and safety of the loading system. Both buffer devices include telescopic chutes with specially designed spiral grooves on the inner side walls. This structure helps guide the smooth descent of the goods, reduces the accumulation and blockage of goods during transportation, and also reduces the wear and tear of the inner side walls of the chutes.
[0054] Further, we have integrated a level sensor at the material receiving end of the telescopic chute. This sensor can monitor the accumulation height of the goods in real time, ensuring the control of material flow during loading, and avoiding excessive loading or material overflow. In addition, to protect the environment and the health of the operators, we have designed a dust cover at the material receiving end of the telescopic chute. This device can effectively reduce the dust generated during the transfer of materials.
[0055] In the design of the receiving hopper 9, we have considered wear resistance and buffer performance. Therefore, the inner side walls of the receiving hopper 9 are specially provided with wear-resistant lining plates and buffer grilles. The wear-resistant lining plates can prolong the service life of the hopper, while the buffer grilles help reduce the impact of materials on the hopper, protecting the integrity of the hopper structure. In addition, to further control dust, we have arranged several dry mist dust suppression nozzles around the mouth of the receiving hopper 9. These nozzles can generate dry mist during material transfer, effectively suppressing dust flying, improving the working environment, and reducing pollution to the surrounding environment.
[0056] Through these optimized designs, our loading system not only improves the loading efficiency, but also enhances the safety and environmental protection of the operation. These improvements make the system more adaptable to various working environments, especially in bulk cargo terminal operations with large water level differences and high efficiency requirements.
[0057] Preferably, the bottom of the receiving hopper 9 is provided with several outlets, and the bottom of the receiving hopper 9 is also provided with a material distributor for distributing the goods to any outlet.
[0058] Preferably, the loading system further includes a series of floating bridges 15, one end of the series of floating bridges 15 being connected to the water engineering platform, and the other end of the series of floating bridges 15 being connected to the pontoon 14.
[0059] Preferably, a sloping walkway 16 is arranged in the direction from the quay wall platform to the water side pontoon platform module for walking.
[0060] Those skilled in the art will readily understand that the above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
