Description

Technical Field

[0001] The present invention belongs to the field of marine equipment, and particularly relates to an automated ship loader and method for port use. Background Art

[0002] A ship loader is a large bulk material machine used for loading ships at bulk material terminals. Ship loaders usually perform continuous loading operations. Therefore, there must be supporting equipment to provide a continuous material flow so that the ship loader can load ships continuously. For example, the feeding of grain silos at grain terminals, the continuous feeding of bucket wheel reclaimers in the stockyards of coal terminals, etc.

[0003] In a specific scenario, first, a primary belt conveyor system continuously transports materials such as coal from the port bulk material yard to the shore base at the ship berth, and then a secondary belt system arranged between the primary belt conveyor system and the cargo ship transfers the bulk materials to the cargo hold of the cargo ship for transshipment.

[0004] In a port scenario where the shore base is relatively low, the cargo hatch of the cargo ship is much higher than the port shore base. The secondary belt system used to transfer the bulk materials of the primary belt conveyor system to the cargo ship must work at a relatively large inclination angle. However, the existing belt conveyor system has a small effective working inclination angle. When the inclination angle becomes larger, the conveying efficiency is greatly reduced, and even the situation where materials move against the operation of the belt conveyor under the action of gravity may occur, making it impossible to transport materials. Summary of the Invention

[0005] In view of the above-mentioned disadvantages of the prior art, the purpose of the present invention is to provide an automated ship loader and method for port use, which is used to solve the problem that the ship loader belt in the prior art cannot transport bulk cargo at a large inclination angle.

[0006] To achieve the above purpose and other related purposes, the present invention provides an automated ship loader and method for port use.

[0007] Among them, an automated ship loader for port use includes a main conveyor and an auxiliary conveyor. The main conveyor includes a material receiving section, a lifting section, and a discharging section connected in sequence. The material receiving section receives the incoming material. The lifting section is obliquely arranged. The end of the discharging section is located at the cargo hatch of the cargo ship. The main conveyor includes a main conveyor belt and a frame. The two sides of the frame are higher than the main conveyor belt to form a material receiving area. The auxiliary conveyor includes an auxiliary conveyor belt. The auxiliary conveyor belt is arranged above the lifting section and covers the starting end and the ending end of the lifting section. The auxiliary conveyor belt covers the material receiving area to form a closed feeding channel. Partition plates are arranged at intervals on the auxiliary conveyor belt. The partition plates divide the closed feeding channel into a plurality of sealed chambers.

[0008] Optionally, the main conveyor further includes a cleaning structure provided at the end of the discharging section. The cleaning structure includes a pressing roller, a cleaning cavity, and a cleaning roller. The pressing roller is provided at the lower rear side of the end of the discharging section and jacks up the main conveyor belt downward, pushing the main conveyor belt into the cleaning cavity. There is cleaning liquid in the cleaning cavity, and the cleaning roller is arranged in the cleaning cavity. Cleaning bristles are provided on the surface of the cleaning roller. The lower cleaning bristles are immersed in the cleaning liquid, and the upper cleaning bristles are in contact with the main conveyor belt.

[0009] Optionally, the cleaning cavity is located at the end of the outer side of the main conveyor. The main conveyor belt is jacked up by the pressing roller and passes through the housing of the cleaning cavity. Hard bristles are provided on the housing of the cleaning cavity, and the ends of the hard bristles are in contact with the surface of the main conveyor belt.

[0010] Optionally, the cleaning cavity is located at the end of the inner side of the main conveyor. The main conveyor belt is jacked up by the pressing roller and passes through the housing of the cleaning cavity. A fan blade roller with fan blades is arranged between the housing of the cleaning cavity and the main conveyor belt.

[0011] Optionally, it further includes a feeding conveyor. The feeding conveyor is arranged perpendicular to the main conveyor. The feeding conveyor includes a feeding conveyor belt and a traversing machine. The traversing machine moves along the feeding conveyor belt and bends the feeding conveyor belt to form an inclined raised portion. The main conveyor is fixedly connected to the traversing machine, and the receiving section is located below the inclined raised portion to receive materials.

[0012] Optionally, the feeding conveyor further includes: A gantry-shaped body slidably mounted on a track, support rollers connected to both sides of the body for supporting the main conveyor belt, and an upper reversing roller and a lower reversing roller for forming the inclined raised portion. Both the upper reversing roller and the lower reversing roller are rotatably connected to the body.

[0013] Optionally, the feeding conveyor further includes belt supporting rollers. A plurality of the belt supporting rollers are installed along the feeding conveyor belt. The belt supporting rollers include telescopic columns on both sides and a supporting roller column horizontally connected between the two telescopic columns. The top height of the supporting roller column is flush with the top height of the support rollers. The width between the two telescopic columns is smaller than the inner width of the gantry-shaped body, and the two sides of the top of the telescopic columns are guiding inclined surfaces.

[0014] Optionally, the telescopic column includes a bottom fixing seat and an upper sliding body. The upper sliding body is slidably connected to the inner cavity of the bottom fixing seat, and an elastic member is arranged between the bottom of the upper sliding body and the bottom of the inner cavity of the bottom fixing seat.

[0015] Optionally, power is transmitted between the pressing roller, the cleaning roller, and the fan blade roller through a conveyor belt.

[0016] Among them, an automated ship loading method for a port uses an automated ship loader for a port as described above, and includes the following steps: The incoming material conveyor belt transports materials from the port yard to the shore corresponding to the port berth. The traversing machine moves along the incoming material conveyor belt to the target cargo ship. The upper reversing roller and the lower reversing roller of the traversing machine bend the incoming material conveyor belt at the corresponding part to form an inclined convex part, and the materials fall from the inclined convex part into the main conveyor. The main conveyor and the auxiliary conveyor lift the materials into the cargo hold of the cargo ship.

[0017] As described above, an automated ship loader and method for a port according to the present invention has at least the following beneficial effects: It can transport bulk cargo at a large inclination angle. In the lifting section of the main conveyor, the partition of the auxiliary conveyor divides the material receiving area of the main conveyor belt into one closed chamber after another. Even if a relatively large inclination angle, or a vertical inclination angle, or even an inclination angle exceeding [specific angle] is used for transportation in the lifting section, the materials will not be unable to be transported along the conveyor belt due to the large transportation angle, thus ensuring the original transportation function and efficiency.

[0027] Please refer to Figures 1 to 7 It should be noted that the structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those skilled in the art to understand and read, and are not used to limit the implementation conditions of the present invention. Therefore, they do not have technical essence.

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" cited in this specification are only for the convenience of clear description and are not used to limit the implementation scope of the present invention. The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope in which the present invention can be implemented.

[0028] The following various embodiments are only for illustration. Combinations can be made between the various embodiments, and it is not limited to the content shown in the following single embodiment.

[0029] In this embodiment, please refer to Figures 1 - 4, An embodiment of an automated ship loader for a port provided by the present invention includes a main conveyor 1 and an auxiliary conveyor. The main conveyor 1 includes a feeding section 10, a lifting section 11, and a discharging section 12 that are connected in sequence. The feeding section 10 receives incoming materials. The lifting section 11 is obliquely arranged to lift the materials upward onto the cargo ship. The end of the discharging section 12 is located at the hatch of the cargo ship 3, so that the materials at its end fall into the cargo hold. The main conveyor 1 includes a main conveyor belt 13 and a frame 14. The two sides of the frame 14 are higher than the main conveyor belt 13 to form a material receiving area 15, which is generally in a "U" - shaped or "V" - shaped cross - section, with a conveyor belt at the bottom and side plates of the frame 14 on both sides; The auxiliary conveyor includes an auxiliary conveyor belt 20. The auxiliary conveyor belt 20 is arranged above the lifting section 11 and covers the starting end and the ending end of the lifting section 11. The auxiliary conveyor belt 20 covers the material receiving area 15 to form a closed feeding channel. Partition plates 22 are arranged at intervals on the auxiliary conveyor belt 20. The partition plates 22 divide the closed feeding channel into multiple sealed chambers 210. A belt or other transmission parts can be used to connect the support rollers of the main conveyor belt 13 and the auxiliary conveyor belt 20, so that the actions of the two are synchronized, and at the same time, the number of power sources is reduced.

[0030] The basic principle of the above - mentioned embodiment is as follows: During the process of the main conveyor 1 transporting materials, the auxiliary conveyor works synchronously with it. In the lifting section 11 of the main conveyor 1, the partition plates 22 of the auxiliary conveyor divide the material receiving area 15 of the main conveyor belt 13 into one - by - one sealed chambers. The effect is that even if the lifting section 11 uses a relatively large inclination angle, or a vertical inclination angle, or even an inclination angle exceeding 90 degrees for transportation, the materials will not be unable to be transported along the conveyor belt due to the large transportation angle, thus ensuring the original transportation function and efficiency.

[0031] This embodiment can refer to Figures 4 - 6 , The main conveyor 1 further includes a cleaning structure 16 arranged at the end of the discharging section 12. The cleaning structure 16 includes a pressing roller 161, a cleaning cavity 162, and a cleaning roller 163. The pressing roller 161 is arranged at the lower rear side of the end of the discharging section 12 and presses the main conveyor belt 13 upward, pushing the main conveyor belt 13 into the cleaning cavity 162. A cleaning liquid is provided in the cleaning cavity 162. An inlet - outlet pipe can be arranged on the cleaning cavity 162 to facilitate the replacement of the cleaning liquid. The cleaning roller 163 is arranged in the cleaning cavity 162. Cleaning bristles 1631 are arranged on the surface of the cleaning roller 163. The lower cleaning bristles 1631 are immersed in the cleaning liquid, and the upper cleaning bristles 1631 are in contact with the main conveyor belt 13. The cleaning roller 163 can be power - connected to the roller of the main conveyor belt 13 through a belt or a gear, etc., so that the two work synchronously and the structural complexity is also reduced.

[0032] The beneficial effects of the above embodiments are as follows: When the main conveyor belt 13 is used to convey bulk materials such as sand, cement, and coal, the conveyed materials are extremely likely to adhere to the surface of the conveyor belt. When the conveyor belt receives bulk materials from the receiving section 10 and then reaches the end of the discharging section 12 along the upper surface of the main conveyor 1, the conveyor belt starts to operate along the lower surface of the main conveyor 1 and prepares for the next cycle. However, during the process of the conveyor belt moving from the lower side of the end of the discharging section 12 along the lower surface of the main conveyor 1 to the receiving section 10, due to reasons such as the vibration of the conveyor belt operation and the gravity of the materials, materials such as coal ash adhering to the surface of the conveyor belt will fall off, resulting in a large amount of coal ash scattered along the layout path of the main conveyor 1 and below the main conveyor 1, which may be the deck of the ship, the water surface between the ship and the shore, and part of the shore ground; and as the main conveyor belt 13 moves back and forth along the ship to load different cargo holds on the ship, it will eventually cause the ship, the water surface, and the ground to be covered with coal ash, which not only results in waste but also increases the cleaning task and even pollutes the environment. With the cleaning function of the cleaning roller 163 and the cleaning bristles 1631 on its surface, the above situation will not occur, which can reduce the cleaning work after the cargo ship is loaded, shorten the berthing time of the cargo ship, and protect the surrounding environment.

[0033] In the previous embodiment, there is also a beneficial effect that the main conveyor belt 13 is cooled by the cleaning liquid. The running length of the main conveyor belt 13 is relatively long, and multiple idlers are required for transmission along the way, and it also bears materials on its surface. Therefore, during the operation of the main conveyor belt 13, friction will cause the temperature of the main conveyor belt 13 to rise, and the performance of the main conveyor belt 13 will decrease with the increase in temperature, such as becoming soft. Due to the cooling effect of the cleaning liquid, the main conveyor belt 13 will always be able to work in a better temperature environment, ensuring the conveying performance and efficiency.

[0034] As a further solution of the above embodiment, the cleaning cavity 162 is located at the end of the outer side of the main conveyor 1. The main conveyor belt 13 is lifted by the pressing roller 161 and passes through the housing of the cleaning cavity 162. Hard bristles 1621 are provided on the housing of the cleaning cavity 162, and the ends of the hard bristles 1621 are in contact with the surface of the main conveyor belt 13.

[0035] The hardness of the hard bristles 1621 means that the bristles can maintain their original shape without bending when not under external force. Compared with soft bristles, they can also clean materials that adhere firmly to the surface of the main conveyor belt 13. First, the hard bristles 1621 clean the surface of the main conveyor belt 13 to remove firmly adhered and excess coal or other materials, allowing them to directly fall into the cargo hold of the cargo ship, which can improve the loading and cleaning efficiency and reduce material backflow. Combining this solution with the previous one can ensure that in the previous solution, only a very small amount of residual coal ash can enter the cleaning cavity 162, relieve the cleaning pressure on the cleaning roller 163 and its surface cleaning bristles 1631, reduce the usage amount of the cleaning liquid in the cleaning cavity 162, and also enable the surface of the main conveyor belt 13 to be cleaned more thoroughly.

[0036] Further, the cleaning cavity 162 is located at the end of the inner side of the main conveyor 1. The main conveyor belt 13 is lifted by the pressing roller 161 and passes through the housing of the cleaning cavity 162. A fan blade roller 164 with fan blades is arranged between the housing of the cleaning cavity 162 and the main conveyor belt 13.

[0037] For the solution in the above embodiment, reference can be made to Figure 5 , the main conveyor belt 13 enters the cleaning cavity 162 from the left top of the cleaning cavity 162 and then leaves the cleaning cavity 162 from the right side of the cleaning cavity 162. During the rotation of the fan blade roller 164, gas can be inhaled from the gap between the right side of the cleaning cavity 162 and the main conveyor belt 13, then pass through the cleaning cavity 162, and be blown out from the left side of the cleaning cavity 162, from the gap between the cleaning cavity 162 and the main conveyor belt 13, that is, at the above-mentioned hard bristles 1621. Its beneficial effects at least include: First, an outward blowing force is formed at the hard bristles 1621 to prevent coal ash from entering the cleaning cavity 162; Second, an air flow is formed at the gap between the left side of the cleaning cavity 162 and the main conveyor belt 13, so as to quickly blow off the cleaning liquid on the surface of the main conveyor belt 13 and prevent the cleaning liquid from following the main conveyor belt 13 and dripping to the bottom. After the excess cleaning liquid is blown back into the cleaning cavity 162, the remaining small amount of cleaning liquid can spontaneously dry during the operation of the main conveyor belt 13 before reaching the receiving section 10 to receive the incoming material, without affecting the material.

[0038] This embodiment can be referred to Figure 2 、 Figure 3 and Figure 7 , and further includes an incoming material conveyor 4. The incoming material conveyor 4 is arranged perpendicular to the main conveyor 1. The incoming material conveyor 4 includes an incoming material conveyor belt 40 and a traversing machine 41. The traversing machine 41 moves along the incoming material conveyor belt 40 and bends the incoming material conveyor belt 40 to form an inclined convex part 401. The main conveyor 1 is fixedly connected to the traversing machine 41. The receiving section 10 is located below the inclined convex part 401 to receive the material.

[0039] In the above embodiments, a dedicated bulk material yard is provided around the berth of the port cargo ship. The starting point of the incoming material conveyor belt 40 is set in the bulk material yard, and the material is continuously sent along the way to the port cargo ship berth. The traversing machine 41 can move along the incoming material conveyor belt 40, and the main conveyor 1 can be fixedly installed on the traversing machine 41 to load cargo ships at different positions. During the movement of the traversing machine 41 along the incoming material conveyor belt 40, it will support and bend the incoming material conveyor belt 40, thereby forming an oblique convex portion 401 as shown in Figure 7 . As a result, the material on the incoming material conveyor belt 40 is cut off by the traversing machine 41 and sent onto the receiving section 10 of the main conveyor 1 located below the oblique convex portion 401. Through the mutual cooperation of the incoming material conveyor belt 40, the traversing machine 41, and the main conveyor 1, the entire ship loading process can be automated. When loading different cargo ships, the switching process is relatively simple, without the need to disassemble and assemble equipment, nor the need for external equipment assistance. Only the traversing machine 41 needs to move forward or backward.

[0040] Furthermore, the incoming material conveyor 4 further includes: a gantry-shaped body 410 slidably installed on the track, support rollers 411 connected to both sides of the body 410 for supporting the main conveyor belt 13, and upper and lower reversing rollers 412 and 413 for forming the oblique convex portion 401. Both the upper and lower reversing rollers 412 and 413 are rotatably connected to the body 410. During the traversing process of the incoming material conveyor 4, it will take over the support work of the incoming material conveyor belt 40 in the target area section and make certain adjustments to the path of the incoming material conveyor belt 40, thereby forming the oblique convex portion 401.

[0041] This embodiment can be referred to Figure 2 and Figure 3 . The incoming material conveyor 4 further includes belt idlers 42. A plurality of belt idlers 42 are installed along the incoming material conveyor belt 40. The belt idler 42 includes telescopic columns 421 on both sides and a support roller 422 horizontally connected between the two telescopic columns 421. The top height of the support roller 422 is flush with the top height of the support roller 411. The width between the two telescopic columns 421 is less than the inner width of the gantry-shaped body 410. The two sides of the top of the telescopic column 421 are guiding inclined surfaces 4210.

[0042] In the above embodiment, the incoming material conveyor belt 40 is supported by the belt rollers 42. However, when the traversing machine 41 moves to a specific area, the support rollers 411, the upper reversing roller 412, and the lower reversing roller 413 on the traversing machine 41 will take over the support work to adjust the incoming material conveyor belt 40 in a local area. The width between the two telescopic columns 421 is smaller than the inner width of the gantry-shaped body 410, so that the traversing machine 41 can move across the belt rollers 42. During the movement of the traversing machine 41, the support roller 411 of the traversing machine 41 will contact the guiding inclined surface 4210 of the support roller 422 on the belt roller 42, thereby pushing the telescopic column 421 downward, causing the support roller 422 to lower and disengage from the support of the incoming material conveyor belt 40, and then being taken over by the support roller 411.

[0043] This embodiment can be referred to Figure 3 , in which one of the telescopic columns 421 is shown in a sectional view. The telescopic column 421 includes a bottom fixed seat and an upper sliding body. The upper sliding body is slidably connected to the inner cavity of the bottom fixed seat, and an elastic member is provided between the bottom of the upper sliding body and the bottom of the inner cavity of the bottom fixed seat. The elastic member can be a spring, so as to be able to complete automatic telescoping. When the traversing machine 41 passes by, the traversing machine 41 causes the telescopic column 421 to automatically lower its height. When the traversing machine 41 leaves, the elastic member makes the telescopic column 421 automatically return to its original position. The beneficial effect is that multiple groups of belt rollers 42 arranged along the incoming material conveyor belt 40 can automatically adjust their own support height according to the position of the traversing machine 41 under the conditions of without an automated control system, without electricity, without communication, etc. It is reliable in operation and simple in maintenance.

[0044] In this embodiment, the pressing roller 161, the cleaning roller 163, and the fan blade roller 164 transmit power to each other through a conveyor belt, which can not only ensure synchronous operation among them, but also reduce the control difficulty and reduce the use of components such as power sources.

[0045] This embodiment is an embodiment of an automated ship loading method for a port. An automated ship loader as described above can be adopted, including the following steps: The incoming material conveyor belt 40 conveys materials from the port yard to the shore corresponding to the port berth. The traversing machine 41 moves along the incoming material conveyor belt 40 to the target cargo ship 3. The upper reversing roller 412 and the lower reversing roller 413 of the traversing machine 41 bend the incoming material conveyor belt 40 at the corresponding part to form an inclined convex part 401. The materials fall from the inclined convex part 401 into the main conveyor 1, and the main conveyor 1 and the auxiliary conveyor lift the materials into the cargo hold of the cargo ship 3. Since the structures and related working processes of the incoming material conveyor belt 40 and the main conveyor 1 have been described in the foregoing embodiments, they will not be described herein again. Through the cooperation of the above-mentioned automatic loading and automatic loading method, the entire loading process can be automated. When loading different cargo ships, the switching process is extremely simple, without the need to disassemble and assemble the loading equipment, nor the need for external equipment assistance. It only requires the traversing machine 41 to move forward or backward.

[0046] In summary, the present invention effectively overcomes various disadvantages in the prior art, can produce beneficial technical effects, and has remarkable progress.

[0047] The above embodiments are only illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
