Description

Technical Field

[0001] This invention relates to the field of cargo loading technology, specifically to a port cargo loading device and method. Background Technology

[0002] Port cargo is highly diverse, with bulk materials such as coal, sand, grain, and cement typically loaded by ship loaders. Existing ship loaders usually consist of a cantilever, belt conveyor, telescopic chute, tail car, traveling mechanism, gantry, and slewing structure. The telescopic chute, the final component in the material handling process, is directly suspended downwards and used to transport materials into the ship's hull. However, existing ship loader telescopic chutes still have some problems in operation, as detailed below:

[0003] Existing telescopic chutes are mainly composed of cloth bags. During use, dust is generated as the bulk material falls. This dust flows upwards within the chute and is discharged from the top, eventually flowing from one end of the belt conveyor into the loading environment. Another portion enters the ship's hull along with the bulk material from the bottom of the chute. This dust is stirred up by the falling material, and combined with the dust from above, it leads to excessive dust during cargo loading, severely impacting the loading environment. Furthermore, existing telescopic chutes are only vertically positioned in the middle during loading. This causes the bulk material to gradually accumulate in a cone shape at the bottom of the chute during loading, resulting in excessive material buildup at the bottom and insufficient material at the edges. This can clog the bottom of the chute, necessitating early raising of the chute to allow material to continue flowing. However, additional leveling of the material inside the ship is still required to ensure sufficient loading. Therefore, existing loading devices are inefficient. To address this, we propose a port cargo loading device and method. Summary of the Invention

[0011] In a preferred embodiment, two rope grooves are symmetrically formed in the middle of the wheel, and two traction ropes are wound and movably arranged in the two rope grooves respectively. One bottom end of the traction rope is fixedly connected to the adjustment component.

[0012] In a preferred embodiment, the top end of the connecting sleeve is provided with a telescopic corrugated pipe that is fixedly connected to the bottom end of the top cylinder. The adjusting component is movably inserted into the clamping seat assembly. The telescopic chute assembly is provided in multiple stacked layers, and the bottom end of the telescopic chute assembly is provided with an installation ring. The outer side of the installation ring is provided with a threaded groove, and the installation ring is located inside the top end of the bottom pipe assembly and is threadedly connected. The bottom end of the suspension rod is fixedly connected to the top end of the dust removal assembly.

[0013] In a preferred embodiment, the base has insertion holes at both ends, which are rotatably connected to the clamping seat assembly. There are two positioning slots, which are symmetrically located on the base. The upper part of the drive screw has a non-threaded section, which is located at the height corresponding to the connecting sleeve.

[0017] In a preferred embodiment, the base is U-shaped, the side groove is located at one of the outer ends and its width is greater than or equal to the width of the base, the end block is elastically telescopic, one end of the insertion rod has a sloping structure on its lower side, and both ends of the base are movably engaged with the insertion rod.

[0018] The specific steps of using a port cargo loading device are as follows:

[0019] S1. Install the bottom end of the telescopic chute assembly and the connecting sleeve, install the bottom pipe assembly and the bottom end of the telescopic chute assembly, check the device and start it.

[0020] S2. Bulk materials are fed in from the feed inlet via an external conveyor belt, then discharged into the bottom pipe assembly through the inner lining spacer ring, and finally fall into the ship. The second motor drives the impeller to rotate during the process, thereby generating suction in the telescopic chute assembly and the bottom pipe assembly, sucking the dust into the base shell, and finally discharging it into the bulk stockpile of the ship from the exhaust pipe at the bottom.

[0021] S3. After loading for a period of time, start the first motor to drive the wheel to rotate, which in turn causes the traction rope on one side to wind up and pull the bottom block, so that the adjustment component on that side rotates slightly around the plug rod connected to the adjustment component on the other side. Then continue to transport bulk materials for loading. After that, the first motor can be turned in the opposite direction again to make the telescopic chute component rotate to the other side until the loading of materials is completed.

[0022] S4. After loading is completed, start the internal motor to drive the drive screw to rotate, which causes the base rings to move upward one by one and collect on the non-threaded section above the drive screw for the next use.

[0023] The present invention has the following beneficial effects:

[0024] 1. The port cargo loading device and method, by installing a dust removal component on the side of the bottom pipe assembly, utilizes the rotation of the dust removal component to centrally adsorb the dust generated by the material inside the telescopic chute assembly during the conveying process, preventing dust from being discharged from the top feed inlet and the bottom pipe assembly and affecting the loading environment. Furthermore, the adsorbed dust can be discharged through the exhaust pipe installed at the bottom into the material. This not only prevents dust from flying but also does not affect the normal loading of materials. Moreover, the structure of this method is simple and effective, eliminating the need for additional dust collection and treatment devices, greatly improving the applicability of the overall device.

[0025] 2. The port cargo loading device and method, by setting the telescopic chute assembly into a multi-layer structure, with base rings spaced apart between each layer, allows the base rings to move using the rotation of the drive screw. Multiple base rings meshing on the drive screw can move simultaneously with the rotation of the drive screw, ensuring that the already extended sack below remains extended. The upper part of the drive screw has a non-threaded section, ensuring that the telescopic chute assembly fitted onto this non-threaded section can maintain this height during rotation, ready to be lowered and deployed at any time. The telescopic chute assembly also has a retractable... The inner lining spacer not only ensures that the material does not directly impact the duct bag during transportation, thus greatly improving the service life of the duct bag, but also provides sufficient flow space for dust generated during material transportation by setting an interval between the duct bag and the inner lining spacer. This, in turn, provides sufficient airflow channels for the bottom dust collection component to adsorb dust, ensuring effective dust adsorption. In particular, when the device rotates the wheel, the telescopic chute assembly tilts at a certain angle, causing the material to impact the inner lining spacer longitudinally during its descent, thus effectively ensuring the integrity of the telescopic chute assembly and demonstrating the applicability of the device.

Detailed Implementation

[0036] 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 port cargo loading device and method involved in the present invention are 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.

[0037] Please see Figure 1-2 A port cargo loading device includes a top cylinder 1, a feed inlet 2 on one side of the top cylinder 1, upright plates symmetrically installed on the top of the top cylinder 1, and a first motor 3 fixedly installed on one side of the upright plate. A rotating wheel 4 is fixedly installed on the output shaft of the first motor 3 via a drive rod. A traction rope 5 is wound on the rotating wheel 4. A connecting sleeve 6 is fixedly installed at the bottom of the top cylinder 1. Adjustment components 7 are symmetrically fixedly installed on both sides of the connecting sleeve 6. A telescopic chute assembly 8 is fixedly installed at the bottom of the connecting sleeve 6. A bottom pipe assembly 9 is fixedly installed at the bottom of the telescopic chute assembly 8. A dust removal component 10 is fixedly installed on one side of the bottom pipe assembly 9. A suspension rod 11 is fixedly installed on one side of the top cylinder 1. Clamping seat assemblies 12 are fixedly installed on both sides of the bottom of the top cylinder 1. An inner lining spacer 13 is movably installed inside the bottom pipe assembly 9. A ventilation grid is evenly opened on the inner lining spacer 13.

[0038] Compared with the prior art, this application provides a dust removal component 10 on the side of the bottom pipe assembly 9. The rotation of the dust removal component 10 allows for the concentrated adsorption of dust generated during the conveying process inside the telescopic chute assembly 8, preventing dust from being discharged from the top inlet 2 and the bottom pipe assembly 9, thus avoiding impact on the loading environment. Furthermore, the adsorbed dust can be discharged through the exhaust pipe 108 at the bottom, which is inserted into the material. This not only prevents dust from flying but also ensures normal loading of the material. The structure is simple and effective, eliminating the need for additional dust collection and processing devices, greatly improving the overall applicability of the device. Additionally, by designing the telescopic chute assembly 8 as a multi-layered structure, with base rings 82 spaced between each layer, the rotation of the drive screw 73 drives the base rings 82 to move. Multiple base rings 82 meshing with the drive screw 73 can move simultaneously with the rotation of the drive screw 73, ensuring the smooth flow of dust from the bottom layer. The unfolded duct bag 81 can remain in an extended state, while the upper part of the drive screw 73 is provided with a non-threaded section. This ensures that the telescopic chute assembly 8, which is fitted onto the non-threaded section, can maintain this height during rotation and is ready to be lowered and unfolded at any time. The telescopic chute assembly 8 is also provided with a retractable inner liner ring 13. This not only ensures that the material does not directly impact the duct bag 81 during the conveying process, but also greatly improves the service life of the duct bag 81. Furthermore, the duct bag 81 and the inner liner ring 13 are spaced apart, which leaves enough flow space for the dust generated during material conveying, and thus provides sufficient airflow channels for the bottom dust collection assembly 10 to adsorb dust, ensuring the adsorption effect. In particular, when the device is rotated by the wheel 4, the telescopic chute assembly 8 is tilted at a certain angle. During the fall, the material will impact the inner liner ring 13 longitudinally, thus ensuring the integrity of the telescopic chute assembly 8 and demonstrating the applicability of the device.

[0039] Please see Figure 1-4 A port cargo loading device includes a turntable 4, with two rope grooves symmetrically opened in the middle of the turntable 4. There are two traction ropes 5, which are respectively located in the two rope grooves and are wound and movable. One bottom end of the traction rope 5 is fixedly connected to the adjustment component 7.

[0040] In this embodiment, it should be noted that the rotation of the wheel 4 can drive the two traction ropes 5 to rotate in opposite directions, thereby realizing the action of one traction rope 5 winding up and the other traction rope 5 unwinding. This causes the adjusting component 7 on one side of the winding traction rope 5 to be pulled upward under its traction, and rotate around the adjusting component 7 on the other side, thereby causing it to tilt the telescopic chute assembly 8. This can expand the range of bulk material that can be transported at the bottom of the telescopic chute assembly 8, thereby improving the efficiency and effect of loading bulk materials on the ship.

[0041] Please see Figure 1-6A port cargo loading device includes a connecting sleeve 6, the top end of which is provided with a telescopic corrugated pipe and fixedly connected to the bottom end of the top cylinder 1; an adjusting component 7 is movably inserted into the clamping seat component 12; multiple telescopic chute components 8 are stacked, and the bottom end of the bottom telescopic chute component 8 is provided with an installation ring; the outer side of the installation ring is provided with a threaded groove, and the installation ring is located inside the top end of the bottom pipe component 9 and threadedly connected; and the bottom end of the suspension rod 11 is fixedly connected to the top end of the dust removal component 10.

[0042] In this embodiment, it should be noted that when adjusting the angle of the telescopic chute assembly 8, the corrugated pipe can be used to ensure the connection between the connecting sleeve 6 and the top cylinder 1, ensuring that the material can be continuously conveyed. The connection method between the telescopic chute assembly 8 and the bottom pipe assembly 9 at the bottom end can facilitate the disassembly of the bottom pipe assembly 9, thereby ensuring the overall ease of use of the device.

[0043] Please see Figure 1-6 A port cargo loading device includes an adjustment assembly 7, which includes a base 71. The base 71 has a positioning groove 72. An internal motor is installed inside the base 71, and a drive screw 73 is fixedly installed on the output shaft of the internal motor. A positioning rod 74 is fixedly installed at the bottom end of the base 71, and a bottom block 75 is installed at the bottom end of the drive screw 73 and the positioning rod 74.

[0044] In this embodiment, it should be noted that the base 71 has insertion holes at both ends, and the insertion holes are rotatably connected to the clamping seat assembly 12. There are two positioning slots 72, which are symmetrically located on the base 71. The upper part of the drive screw 73 is provided with a non-threaded section, which is located at the position corresponding to the height of the connecting sleeve 6. There are two positioning rods 74, which are symmetrically located on both sides of the drive screw 73. The bottom end of the drive screw 73 is rotatably located on the bottom block 75. In this way, the internal motor can drive the drive screw 73 to rotate, thereby allowing the telescopic chute assembly 8 sleeved on it to move up and down with the rotation of the drive screw 73 to adjust its extension degree, thereby realizing the extension control of the telescopic chute assembly 8. At the same time, it can also serve as a support drive for the lateral rotation of the telescopic chute assembly 8, driving the traction telescopic chute assembly 8 to rotate and expand the discharge range at the bottom of the telescopic chute assembly 8, thereby improving the loading effect of the device.

[0045] Please see Figure 2-7 A port cargo loading device includes a telescopic chute assembly 8, which includes a tubular bag 81. A base ring 82 is fixedly installed at one end of the tubular bag 81. The tubular bag 81 and the base ring 82 are fixedly installed alternately. An mounting base block 83 is fixedly installed on the upper surface of the top base ring 82, and a threaded sleeve 84 is fixedly installed on the top base ring 82.

[0046] In this embodiment, it should be noted that a mounting ring with a threaded groove is fixedly installed at the bottom of the bottom tube 81, and the mounting ring is threadedly connected to the top of the bottom tube assembly 9. The drive screw 73 passes through the threaded sleeve 84 and is threadedly connected to its interior. The mounting base block 83 is fixedly connected to the bottom of the connecting sleeve 6 by mounting screws. The top of the inner lining spacer ring 13 is fixedly connected to the inner ring of the top base ring 82. In this way, the rotation of the drive screw 73 can drive the base rings 82 to move one by one on the drive screw 73, thereby causing the tube 81 to unfold downwards for material transfer.

[0047] Please see Figure 7-8 A port cargo loading device includes a bottom pipe assembly 9, the bottom pipe assembly 9 includes a pipe body 91, an annular groove 92 is provided above the pipe body 91, and an inner ring 93 is fixedly installed inside the pipe body 91.

[0048] In this embodiment, it should be noted that a support rod is provided at the bottom end of the tube body 91, and the support rod supports the bottom end of the inner lining spacer ring 13. The mounting ring provided on the tube bag 81 is threadedly connected to the ring groove 92. The inner ring 93 is placed at intervals inside the tube body 91, so that the inner lining spacer ring 13 can be placed therein. Then, the extension of the telescopic chute assembly 8 is used to drive the inner lining spacer ring 13 to extend and retract, thereby ensuring that the material will not directly impact the tube bag 81 during the downward conveying process, ensuring the integrity and service life of the tube bag 81. At the same time, the spaced inner ring 93 can ensure the smooth flow of air in it, thereby ensuring the dust adsorption effect of the dust removal assembly 10 on dust.

[0049] Please see Figure 2-9 A port cargo loading device includes a dust removal assembly 10, which includes a base shell 101. A second motor 102 is fixedly installed on the outside of the base shell 101. An impeller 103 is fixedly installed on the output shaft of the second motor 102 inside the base shell 101. A pin block 104 is fixedly installed at the top of the base shell 101. A horizontal plate 105 is movably installed on the pin block 104. A partition ring 106 is fixedly installed at one end of the horizontal plate 105. An air inlet hose 107 is fixedly installed at one end of the partition ring 106. An exhaust pipe 108 is fixedly installed at the bottom of the base shell 101.

[0050] In this embodiment, it should be noted that the pin block 104 and the horizontal plate 105 are rotatably connected. The top end of the horizontal plate 105 is fixedly installed with the bottom end of the suspension rod 11. The partition ring 106 is set perpendicular to the horizontal plate 105 and a duct hose is provided between it and the base shell 101. The air inlet hose 107 is sealed and connected to the inside of the pipe body 91. The exhaust pipe 108 is inserted into the bulk material. In this way, the impeller 103 can be rotated by the second motor 102, forming a suction force inside the telescopic chute assembly 8 and the bottom pipe assembly 9, which adsorbs the dust formed during the conveying of the bulk material into the base shell 101, and then discharges it into the bulk material that has been conveyed into the ship and accumulated inside through the exhaust pipe 108. In this way, the setting of the inner lining partition ring 13 can not only separate the dust in the bulk material well, but also convey the dust into the bulk material through the exhaust pipe 108. There is no need to set up an additional dust collection and treatment device. While ensuring the dust treatment effect, the structure of the device is greatly simplified and the applicability of the device is improved.

[0051] Please see Figure 2-5 A port cargo loading device includes a clamping seat assembly 12, which includes a seat body 121. The seat body 121 has a side groove 122. End blocks 123 are movably installed on both sides inside the seat body 121, and a plug rod 124 is fixedly installed at the end of the end block 123.

[0052] In this embodiment, it should be noted that the base 121 is U-shaped, with a side groove 122 located at one outer end and its width being greater than or equal to the width of the base 71. The end block 123 is elastically telescopic. One end of the insertion rod 124 has a sloping structure on its lower side. Both ends of the base 71 are engaged with the insertion rod 124 and are movably mounted. In this way, when the traction rope 5 does not generate an upward traction force, the insertion rod 124 can be used to support the base 71. When the traction rope 5 generates a traction force on one side, due to the sloping structure on the lower surface of the insertion rod 124, the base 71 can smoothly compress the end block 123 and slowly detach it from the insertion rod 124. This can then cause the telescopic chute assembly 8 to tilt, increasing the bottom discharge range of the telescopic chute assembly 8 and thus improving the loading effect of the device.

[0053] The specific steps of using a port cargo loading device are as follows:

[0054] S1. Install the bottom end of the telescopic chute assembly 8 and the connecting sleeve 6, install the bottom pipe assembly 9 and the bottom end of the telescopic chute assembly 8, check the device and start it.

[0055] S2. Bulk materials are fed in from the feed inlet 2 via an external conveyor belt, then discharged into the bottom pipe assembly 9 through the inner liner 13, and finally fall into the ship. During the process, the second motor 102 drives the impeller 103 to rotate, thereby generating suction in the telescopic chute assembly 8 and the bottom pipe assembly 9, sucking the dust into the base shell 101, and finally discharging it into the bulk stockpile of the ship from the exhaust pipe 108 at the bottom.

[0056] S3. After loading for a period of time, start the first motor 3 to drive the wheel 4 to rotate, which in turn causes the traction rope 5 on one side to wind up and pull the bottom block 75, so that the adjustment component 7 on that side rotates slightly around the plug rod 124 connected to the adjustment component 7 on the other side. Then continue to transport bulk materials for loading. After that, the first motor 3 can be rotated in the opposite direction again to make the telescopic chute assembly 8 rotate to the other side until the loading of materials is completed.

[0057] S4. After loading is completed, start the internal motor to drive the drive screw 73 to rotate, which causes the base rings 82 to move upward one by one and collect on the non-threaded section above the drive screw 73 for the next use.

[0058] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
