Description

Technical Field

[0001] This application relates to transportation operation equipment, and more particularly to a ship unloader. Background Technology

[0002] A ship unloader is a machine used on shore to move cargo from inside a cargo ship. In operation, a ship unloader uses lifting equipment to raise the cargo, and then uses conveyor belts or other transport equipment connected to the lifting equipment to transport it to a designated location on shore.

[0003] The ship unloaders using this technology also have certain drawbacks. In these machines, the bottom of the lifting equipment is connected to a bag retrieval machine inside the ship's hold. Because the bag retrieval machine is in contact with the hold, it is affected by fluctuations in the hold, which are then transmitted to the lifting equipment. This causes changes in the lifting equipment's posture, affecting cargo transport. Summary of the Invention

[0004] This application provides a ship unloader with high assembly efficiency. To achieve the above objective, this application adopts the following technical solution:

[0006] As an optional implementation, the transport body also includes: a tail conveyor; and a traveling frame for movably supporting the tail conveyor, the traveling frame being hinged to the second end of the support truss so that the inlet end of the tail conveyor is aligned with the outlet end of the intermediate conveyor.

[0007] As an optional implementation, the transport body further includes: at least one second telescopic rod, the first end of each second telescopic rod being hinged to the traveling frame, and the second end of each second telescopic rod being hinged to the support truss, so as to adjust the posture of the support truss by extending and retracting the second telescopic rod.

[0008] As an alternative implementation, the tail conveyor extends downward from its inlet end to its outlet end.

[0009] As an optional implementation, the transport body also includes a counterweight, which is mounted on the traveling frame to balance the transport body.

[0010] As an optional implementation, the intermediate conveyor also includes an intermediate conveying section and an intermediate insulation cover, with the intermediate insulation cover covering the intermediate conveying section; the main transport body also includes a tail conveyor, which includes a tail conveying section and a tail insulation cover, with the inlet end of the tail conveying section connected to the outlet end of the intermediate conveying section, and the tail insulation cover covering the tail conveying section.

[0011] As an optional implementation, there are two upper loading platforms arranged side by side; the intermediate conveyor has two sets of intermediate conveying sections arranged side by side, and the inlet ends of the two sets of intermediate conveying sections are respectively connected to the two upper loading platforms.

[0012] As an optional implementation, the ship unloader also includes a tail conveyor having two sets of tail conveying sections arranged in parallel, which are respectively connected to two intermediate conveying sections.

[0013] As an optional implementation, the lifting mechanism further includes: a telescopic frame connected to the main frame and capable of moving along the axial direction of the main frame, the telescopic frame being provided with at least one loading platform, and the loading platform being located below the upper loading platform; at least one set of lifting machines, the lifting machines, the loading platform and the upper loading platform corresponding one-to-one, each set of lifting machines having at least one lifting part, the lifting machines being configured to drive at least one lifting part to move, so as to transfer the goods on the loading platform to the upper loading platform.

[0014] As an optional implementation, there are two upper loading platforms arranged side by side; there are two lower loading platforms arranged side by side; there are two sets of elevators arranged side by side, with each set of elevators corresponding to one upper loading platform and one lower loading platform.

[0015] In the ship unloader of this application, the supporting truss of the transport body is hinged to the main frame of the lifting mechanism, and the first end of the first telescopic rod is hinged to the main frame, while the second end of each first telescopic rod is hinged to the supporting truss. Thus, by pulling or pushing the main frame of the lifting mechanism with the first telescopic rod, the tilt angle of the main frame can be adjusted, thereby adjusting the attitude of the entire lifting mechanism. In this way, even if the entire lifting mechanism is affected by external factors (such as the swaying of the cargo ship), the first telescopic rod can ensure that the overall attitude of the lifting mechanism does not change significantly, ensuring the stability of the entire ship unloader system and improving reliability.

Detailed Implementation

[0026] In existing ship unloading machines, the bottom of the lifting equipment is connected to the bag retrieval machine inside the ship's hold. Since the bag retrieval machine is in contact with the ship's hold, it will be affected by the fluctuations in the hold, which will then be transmitted to the lifting equipment, causing changes in the lifting equipment's posture and affecting cargo transportation.

[0027] To overcome the shortcomings of the prior art, this application provides a ship unloader in which the supporting truss of the transport body is hinged to the main frame of the lifting mechanism, and the first end of the first telescopic rod is hinged to the main frame, while the second end of each first telescopic rod is hinged to the supporting truss. Thus, by pulling or pushing the main frame of the lifting mechanism with the first telescopic rod, the tilt angle of the main frame can be adjusted, thereby adjusting the posture of the entire lifting mechanism. In this way, even if the entire lifting mechanism is affected by external factors (such as the swaying of the cargo ship), the first telescopic rod can ensure that the overall posture of the lifting mechanism does not change significantly, ensuring the stability of the entire ship unloader system and improving reliability.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will be combined with the embodiments of this application. Figures 1 to 7 The technical solutions in the embodiments of this application are clearly and completely described. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] This application provides a ship unloader that can be used to transport cargo from a ship's hold. The ship unloader may include a transport body 100, a lifting mechanism, and at least one first telescopic boom 130.

[0030] The transport body 100 is located on shore and is used for transporting goods. The transport body 100 includes a support truss 110 and an intermediate conveyor 120, with the support truss 110 supporting the intermediate conveyor 120. A lifting mechanism is installed in the ship's hold to lift goods onto the intermediate conveyor 120. The lifting mechanism includes a main frame 200, which has at least one upper loading platform 210 for carrying goods. The main frame 200 is hinged to a first end of the support truss 110 so that the upper loading platform 210 is aligned with the entrance end of the intermediate conveyor 120. A first end of each first telescopic rod 130 is hinged to the main frame 200, and a second end of each first telescopic rod 130 is hinged to the support truss 110, allowing adjustment of the main frame 200's posture by extending and retracting the first telescopic rods 130.

[0031] The main transport vehicle 100 is located on shore, and at least part of the lifting mechanism is located inside the ship's hold. The lifting mechanism raises the cargo inside the hold to the upper loading platform 210 of the main frame 200. Since the main frame 200 is hinged to the supporting truss 110, the upper loading platform 210 is connected to the entrance end of the intermediate conveyor 120, so that the cargo on the upper loading platform 210 can continue to be transported to shore via the intermediate conveyor 120.

[0032] In this embodiment, the support truss 110 of the transport body 100 is hinged to the main frame 200 of the lifting mechanism, and the first end of the first telescopic rod 130 is hinged to the main frame 200, while the second end of each first telescopic rod 130 is hinged to the support truss 110. Therefore, the main frame 200 of the lifting mechanism can be pulled or pushed by the first telescopic rod 130, thereby adjusting the tilt angle of the main frame 200 and adjusting the posture of the entire lifting mechanism. In this way, even if the entire lifting mechanism is affected by external factors (such as the swaying of the cargo ship), the first telescopic rod 130 can ensure that the overall posture of the lifting mechanism does not change significantly, ensuring the stability of the entire unloading machine system and improving reliability.

[0033] In some specific embodiments, the first telescopic rod 130 may be configured as a hydraulic rod. The number of first telescopic rods 130 may be two, three, or more, so as to jointly maintain the posture of the lifting mechanism.

[0034] In some embodiments, the transport body 100 may further include a tail conveyor 140 and a traveling frame 150. The traveling frame 150 is used to movably support the tail conveyor 140. The traveling frame 150 is hinged to a second end of the support truss 110 so that the inlet end of the tail conveyor 140 is aligned with the outlet end of the intermediate conveyor 120.

[0035] Both the intermediate conveyor 120 and the tail conveyor 140 can be conveyor belt conveyors. The main body of the traveling frame 150 can be a truss structure made of channel steel, H-beams, or other profiles, which is relatively simple and lightweight. The traveling frame 150 also includes a traveling drive mechanism, which can be a heavy-duty AGV with autonomous walking capabilities.

[0036] After the traveling frame 150 is hinged to the second end of the support truss 110, the inlet end of the tail conveyor 140 is connected to the outlet end of the intermediate conveyor 120, so that the goods on the intermediate conveyor 120 can enter the tail conveyor 140 and continue to be transported by the tail conveyor 140.

[0037] Furthermore, the transport body 100 may also include at least one second telescopic rod 180, with the first end of each second telescopic rod 180 hinged to the walking frame 150 and the second end of each second telescopic rod 180 hinged to the support truss 110, so as to adjust the posture of the support truss 110 by the extension and retraction of the second telescopic rod 180.

[0038] In this embodiment, the first end of the second telescopic rod 180 is hinged to the traveling frame 150, and the second end of each second telescopic rod 180 is hinged to the support truss 110. Therefore, the pitch angle of the support truss 110 can be adjusted by pulling or pushing the support truss 110 through the extension and retraction of the second telescopic rod 180, thereby adjusting the pitch angle of the intermediate conveyor 120.

[0039] Furthermore, the tail conveyor 140 extends downward from its inlet end to its outlet end, so that the outlet end of the tail conveyor 140 is close to the ground, thus allowing the goods on it to be transported to the vicinity of the ground.

[0040] In some embodiments, the transport body 100 may further include a counterweight 160, which is disposed on the walking frame 150 to balance the transport body 100.

[0041] Since the second end of the traveling frame 150 is hinged to the support truss 110, and the traveling frame 150 is used to movably support the tail conveyor 140, that is, the traveling frame 150 is the main stress point of the shore equipment of the ship unloader. Moreover, the support truss 110 and the intermediate conveyor 120 are tilted relative to the traveling frame 150, which makes the overall structure of the traveling frame 150 unbalanced. In this embodiment, a counterweight 160 is provided in the traveling frame 150 to make the overall structure more balanced and ensure the stability of the transportation process.

[0042] In some embodiments, the ship unloader may further include an electro-hydraulic unit 170, which can be used to provide hydraulic control of the first telescopic boom 130 and the second telescopic boom 180. The housing of the electro-hydraulic unit 170 is a standard shipping container, which can be arranged on the traveling frame 150. This allows for a more compact overall design and provides a certain amount of counterweight to the traveling frame 150 to balance it.

[0043] In some embodiments, the intermediate conveyor 120 may further include an intermediate conveying section 122 and an intermediate insulation cover 124. The intermediate insulation cover 124 covers the intermediate conveying section 122, and the intermediate conveying section 122 can play a role in heat preservation and protection, reducing the probability of goods being damaged during transportation.

[0044] Furthermore, the transport body 100 also includes a tail conveyor 140, which may further include a tail conveying section 142 and a tail insulation cover 144. The inlet end of the tail conveying section 142 is connected to the outlet end of the intermediate conveying section 122, and the tail insulation cover 144 is installed over the tail conveying section 142. The tail conveying section 142 can provide insulation and protection, reducing the probability of damage to goods during transport.

[0045] In some embodiments, there are two upper loading platforms 210 arranged side by side. The intermediate conveyor 120 has two sets of intermediate conveying sections 122 arranged side by side, which are connected to the two upper loading platforms 210.

[0046] In this embodiment, the lifting mechanism can simultaneously lift goods onto two upper loading platforms 210, and the two upper loading platforms 210 respectively transport goods to two intermediate conveying sections 122. This "dual-channel" conveying method can improve work efficiency.

[0047] Furthermore, the tail conveyor 140 has two sets of tail conveying sections 142 arranged in parallel, and the two sets of tail conveying sections 142 are respectively connected to the two intermediate conveying sections 122. In this way, the two tail conveying sections 142 of the tail conveyor 140 can respectively receive the goods output from the two intermediate conveying sections 122 of the intermediate conveyor 120, thereby improving work efficiency.

[0048] In some embodiments, the lifting mechanism may further include a telescopic frame 300 and at least one set of lifting machines 400. The telescopic frame 300 is connected to the main frame 200 and is movable along the axial direction of the main frame 200. The telescopic frame 300 is provided with at least one loading platform 310, and the loading platform 310 is located below the loading platform 210. The lifting machines 400, the loading platform 310, and the loading platform 210 correspond one-to-one. Each set of lifting machines 400 has at least one lifting part 410, and the lifting machine 400 is configured to drive at least one lifting part 410 to move in order to transfer the goods on the loading platform 310 to the loading platform 210.

[0049] Specifically, the telescopic frame 300 is fitted inside the main frame 200 so that it can move axially along the main frame 200. At least one elevator 400 may be disposed inside the telescopic frame 300 to lift goods on the loading platform 310 to the loading platform 210.

[0050] In some embodiments, the elevator 400, the download platform 310, the loading platform 210, the intermediate conveying section 122 of the intermediate conveyor 120, and the tail conveying section 142 of the tail conveyor 140 correspond one-to-one.

[0051] For example, the elevator 400, the download platform 310, the loading platform 210, the intermediate conveyor 122, and the tail conveyor 142 are each set in a one-to-one correspondence. The elevators 400 are arranged side by side, the two download platforms 310 are arranged side by side, the two loading platforms 210 are arranged side by side, the intermediate conveyor 122 is arranged side by side, and the two tail conveyors 142 are arranged side by side. In this way, each elevator 400 lifts the goods on the corresponding download platform 310 to the corresponding loading platform 210, the loading platform 210 conveys the goods to the corresponding intermediate conveyor 122, and the intermediate conveyor 122 conveys the goods to the corresponding tail conveyor 142.

[0052] In some embodiments, each elevator 400 may further include a frame 420 and a drive chain 430. The frame 420 is fixed inside the telescopic frame 300 and has an annular guide rail 422. The drive chain 430 is disposed on the annular guide rail 422, and at least one lifting part 410 is disposed on the drive chain 430. The drive chain 430 is configured to move controllably along the annular guide rail 422 to drive at least one lifting part 410 to move up and down around the platform 310, such that the lifting part 410 passes through the lower loading platform 310 from bottom to top to transfer goods on the lower loading platform 310 to the lifting part 410, and passes through the upper loading platform 210 from top to bottom to transfer goods on the lifting part 410 to the upper loading platform 210.

[0053] In this embodiment, the frame 420 can be fixed inside the telescopic frame 300 by fasteners, and the transmission chain 430 is set inside the annular guide rail 422 so as to hide it.

[0054] The lifting part 410 is fixedly mounted on the transmission chain 430 and protrudes from the frame 420, so that the lifting part 410 can move up and down in a circular motion under the drive of the transmission chain 430.

[0055] In this embodiment, the lifting section 410 moves vertically in a circular motion. Specifically, each lifting section 410 may first move upward in a straight line, then turn at the highest point to move downward, and finally turn at the lowest point to move upward, in a continuous cycle.

[0056] Both the upper loading platform 210 and the lower loading platform 310 can be positioned between the highest and lowest points of the lifting unit 410's operation. The lower loading platform 310 can be positioned on the upward movement trajectory of the lifting unit 410, and the upper loading platform 210 can be positioned on the downward movement trajectory of the lifting unit 410. In this way, the lifting unit 410 can pass through the lower loading platform 310 from bottom to top to take away the goods on the lower loading platform 310, and pass through the upper loading platform 210 from top to bottom to transfer the goods to the upper loading platform 210.

[0057] Therefore, the unloader in this embodiment of the application uses the vertically rotating lifting part 410 to lift the cargo by passing through the loading platform 310 and the loading platform 210. There is no interruption during the lifting process, and the path is relatively short, so the lifting efficiency is high.

[0058] Furthermore, each hoist 400 may also include a circumferential drive mechanism, which includes a circumferential motor 440 and a sprocket assembly 450. The circumferential motor 440 is fixed to the frame 420 and connected to the sprocket assembly 450. The transmission chain 430 is disposed on the sprocket assembly 450.

[0059] Specifically, the sprocket assembly 450 may include an upper sprocket 452 and a lower sprocket 454, both of which are rotatably mounted on the frame 420. A drive chain 430 is stretched between the upper sprocket 452 and the lower sprocket 454 and engages with them. A circular motor 440 may be connected to either the upper sprocket 452 or the lower sprocket 454 to drive one of them, which in turn drives the other to rotate via the drive chain 430.

[0060] In some embodiments, each lifting unit 410 has a plurality of spaced-apart forks 411. The plurality of forks 411 may be arranged horizontally to form a bearing surface for carrying goods. The lifting unit 410 also includes a mounting bracket 412, through which the plurality of forks 411 are fixed to the frame 420.

[0061] The loading platform 310 has multiple loading cylinders 312 spaced apart. These loading cylinders 312 can also be arranged horizontally, collectively forming a loading surface for carrying goods. On the operating trajectory of the lifting unit 410, multiple forks 411 are staggered with the multiple loading cylinders 312. When the lifting unit 410 passes through the loading platform 310, the multiple forks 411 pass through the gaps between the multiple loading cylinders 312.

[0062] The upper loading platform 210 has multiple spaced loading cylinders 212. On the running trajectory of the lifting unit 410, multiple loading forks 411 are staggered with the multiple loading cylinders 212. When the lifting unit 410 passes through the upper loading platform 210, the multiple loading forks 411 pass through the gaps between the multiple loading cylinders 212.

[0063] During a cargo lifting operation, the lifting unit 410 turns upward at its lowest point, passing through the loading platform 310 from bottom to top. Multiple forks 411 of the lifting unit 410 pass through multiple loading bins 312 of the loading platform 310 to lift the cargo from the loading bins 312 upwards. As the lifting unit 410 turns downward at its highest point, it passes through the upper loading bins 212 from top to bottom. Multiple forks 411 of the lifting unit 410 pass through the upper loading bins 212 of the upper loading platform 210, leaving the cargo on the upper loading platform 210.

[0064] Furthermore, the loading platform 310 also has a loading rack 314, in which a plurality of loading cylinders 312 are rotatably arranged on the loading rack 314 around their respective circumferences, so as to transfer goods from the outside to the loading platform 310.

[0065] Specifically, the multiple loading cylinders 312 can be driven to rotate by a drive motor, or they can be rotated by the friction of the cargo.

[0066] In this embodiment, the multiple loading cylinders 312 are configured to rotate around their respective circumferences. This reduces friction during the transfer of goods to the loading platform 310, making the transfer process more convenient and efficient.

[0067] Furthermore, the upper loading platform 210 also has upper loading racks 214, wherein a plurality of upper loading racks 214 are rotatably arranged on the upper loading platform 210 about their respective circumferences, so as to transfer goods out of the upper loading platform 210.

[0068] Similarly, the multiple loading cylinders 212 can be driven to rotate by a drive motor, or they can rotate due to the friction of the goods. The multiple loading cylinders 212 are configured to rotate around their respective circumferences, which reduces friction during the transfer of goods onto the transport body 100, making the transfer process more convenient and efficient.

[0069] In some embodiments, the lifting mechanism may further include a transport machine 500, which is disposed outside the main frame 200 and connected to the loading platform 310 for transporting goods to the loading platform 310.

[0070] In some specific embodiments, the transport machine 500 may be a telescopic roller conveyor. The telescopic roller conveyor, equipped with rollers, can be flexibly bent and can be assembled in groups, providing a wide operating range within the cargo hold, thereby saving time on the relocation of the unloader and improving operational efficiency.

[0071] When the telescopic frame 300 is lowered to the bottom of the cabin, it can be connected to the telescopic roller with fasteners, and the outlet of the telescopic roller machine is aligned with the loading platform 310 on the telescopic frame 300.

[0072] During operation, packages and cargo in the ship's hold are manually moved to the telescopic roller conveyor and transported to the loading platform 310 on the telescopic frame 300. They are then lifted by the hoist 400 to the loading platform and finally transported to the shore by the main transport unit 100.

[0073] Furthermore, the loading platform 310 also includes a protective plate 316, which is located on the side of the loading platform 310 away from the conveyor 500 to stop the goods and prevent them from falling.

[0074] Furthermore, the loading platform 310 may also include a stop plate 317, which is movably disposed on the side of the loading platform 310 near the conveyor 500. The stop plate 317 has a stopping state and a releasing state. When in the stopping state, the stop plate 317 protrudes from the upper surface of the loading platform 310. When in the releasing state, the stop plate 317 avoids the upper surface of the loading platform 310.

[0075] In this embodiment, the stop plate 317 can control the goods entering the loading platform 310 by switching between the stop state and the release state. This can prevent subsequent goods from crowding the loading platform 310 when the goods on it have not been transferred out, prevent multiple goods from blocking the path of the lifting part 410, and also prevent multiple goods from being taken away at the same time when they are on the loading platform 310, thus preventing them from falling.

[0076] Furthermore, the lifting device is also configured to: drive the stop plate 317 into a release state when a lifting part 410 is detected approaching below the download platform 310, or drive the stop plate 317 into a stop state when no lifting part 410 is detected approaching below the download platform 310.

[0077] In this way, when a lifting part 410 is detected approaching from below the loading platform 310, it can be assumed that a lifting part 410 is about to lift the goods. At this time, the stop plate 317 is driven to avoid the upper surface of the loading platform 310, allowing the goods to enter the loading platform 310. When the lifting part 410 arrives, it can take away the goods without causing the goods to be stuck.

[0078] When no lifting part 410 is detected approaching from below the loading platform 310, the drive stop plate 317 is in a stop state. At this time, the drive stop plate 317 protrudes from the upper surface of the loading platform 310, preventing goods from entering the loading platform 310 and avoiding goods from being stuck on the loading platform 310 for a long time.

[0079] In some embodiments, the loading platform 310 further includes a stop bracket 318 and a drive push rod 319. The stop bracket 318 is fixed to the side of the loading platform 310 near the conveyor 500. The drive push rod 319 is disposed on the stop bracket 318 and connected to a stop plate 317, and the drive push rod 319 is configured to controllably drive the stop plate 317 to switch between a stop state and a release state.

[0080] In some specific embodiments, the drive push rod 319 can be configured as a power cylinder (pneumatic or hydraulic), the main body of the power cylinder is fixed on the stop bracket 318, and the piston of the power cylinder is connected to the stop plate 317.

[0081] When the stop plate 317 switches from the release state to the stop state, the piston of the power cylinder controller extends upward to push the stop plate 317 upward, protruding from the upper surface of the download stage 310. When the stop plate 317 switches from the stop state to the release state, the piston of the power cylinder controller retracts downward to retract the stop plate 317 downward to below the download stage 310, thus avoiding the upper surface of the download stage 310.

[0082] In some embodiments, the lifting mechanism may further include a lifting drive mechanism disposed between the main frame 200 and the telescopic frame 300, for controlled lifting of the telescopic frame 300.

[0083] During the initial assembly, the main frame 200, telescopic frame 300, and hoist 400 are installed first. The transport vehicle 100 approaches the cargo ship and stops. The telescopic frame 300 is then raised within the main frame 200 to a suitable position, ensuring it is above the hatch opening and its lowest point is higher than the top of the hatch to maintain a safe distance. Finally, the telescopic frame 300 is propelled over the hatch roof and into the interior via the lifting drive mechanism. The telescopic frame 300 remains vertical to the bottom of the hatch. Pressure sensors and anti-collision blocks are installed at the bottom of the telescopic frame 300. As the telescopic frame 300 descends towards the bottom of the hatch, it gradually decelerates and lands on the bottom of the hatch. After the transport operation is completed, the telescopic frame 300 is raised out of the hatch roof via the lifting drive mechanism, and the transport vehicle 100 drives the vehicle back to shore along with the telescopic frame 300 and its lifting mechanism.

[0084] Therefore, the lifting mechanism of this embodiment, which sends the telescopic frame 300 into and out of the cabin through the lifting drive mechanism, is simple and easy to implement, and the disassembly is efficient, which helps to improve the transfer efficiency.

[0085] In some embodiments, the lifting drive mechanism may further include a lifting motor 600 and a transmission component 610. The lifting motor 600 is fixed to the main frame 200, and the transmission component 610 is mounted on the output shaft of the lifting motor 600 and connected to the telescopic frame 300.

[0086] Furthermore, the transmission component 610 can also be configured as a gear and rack mechanism. Specifically, the transmission component 610 may include a gear 612 and a rack 614, wherein the gear 612 is mounted on the lifting motor 600, and the rack 614 is connected to the telescopic frame 300 and meshes with the gear 612. When the telescopic frame 300 is being raised or lowered, the lifting motor 600 is started, the lifting motor 600 drives the gear 612 to rotate, the gear 612 drives the rack 614 to move up and down, and the rack 614 drives the telescopic frame 300 to move up and down.

[0087] Of course, the transmission component 610 may not be limited to the gear and rack mechanism mentioned above. The transmission component 610 may also be configured as other linear conversion mechanisms, such as ball screw mechanisms.

[0088] Furthermore, the lifting drive mechanism may also include a reducer, which may be disposed between the reducer and the transmission component 610 to reduce the speed of the lifting motor 600, so as to control the lifting rate of the telescopic frame 300 within a reasonable and stable range and avoid accidents.

[0089] In some embodiments, the lifting motor 600 may further include a clutch 620, which is disposed on the output shaft of the lifting motor 600 and is used to release or maintain the output of the lifting motor 600 to the transmission member 610.

[0090] In some specific embodiments, the clutch 620 may be an electromagnetic clutch, which is a device that uses electromagnetic force to achieve the clutch action. Its working principle is: when energized, the electromagnetic coil generates a magnetic field, which attracts or repels the moving part of the clutch 620, thereby realizing the transmission or interruption of power.

[0091] As can be seen from the above, during the assembly process, the telescopic frame 300 is lowered into the cabin using a lifting drive mechanism. During the handling operation, the telescopic frame 300 needs to maintain a free lifting state relative to the main frame 200 so that it can float up as the cabin floats.

[0092] In this embodiment, the clutch 620 is located on the output shaft of the lifting motor 600 and can control the output of the lifting motor 600 to the transmission component 610.

[0093] During assembly, the clutch 620 is controlled to maintain the output of the lifting motor 600 to the transmission component 610, so that the telescopic frame 300 is driven to rise and fall through the output of the lifting motor 600 to the transmission component 610.

[0094] During the transportation operation, the control clutch 620 releases the output of the lifting motor 600 to the transmission component 610, so that the telescopic frame 300 is in a free lifting state. As the cargo in the hold is continuously transported out, the hold causes the telescopic frame 300 to float. The telescopic frame 300 floats relative to the main frame 200 without affecting the main frame 200, and thus will not cause the swaying of the transport body 100 or the change of the transport angle of the transport body 100.

[0095] In some embodiments, the ship unloader may further include at least one set of limiting mechanisms for constraining the lifting trajectory of the telescopic frame 300. Each set of limiting mechanisms includes a guide rail 650 and a guide wheel 640 that cooperates with the guide rail 650. The guide rail 650 is disposed on one of the main frame 200 and the telescopic frame 300, and the guide wheel 640 is disposed on the other of the main frame 200 and the telescopic frame 300.

[0096] In some specific embodiments, two sets of limiting mechanisms are provided, with the two sets of limiting mechanisms respectively located on opposite sides of the telescopic frame 300.

[0097] Furthermore, the guide rail 650 can be fastened to the telescopic frame 300, and the guide wheel 640 is rotatably mounted to the main frame 200, with at least a portion of the guide wheel 640 extending into the interior of the guide rail 650 to engage with it. During the lifting and lowering of the telescopic frame 300, the engagement of the guide wheel 640 and the guide rail 650 constrains the lifting and lowering trajectory of the telescopic frame 300. In addition, the rotatable arrangement of the guide wheel 640 within the guide rail 650 effectively reduces friction between the two, resulting in smoother lifting and lowering of the telescopic frame 300 and reduced noise.

[0098] Of course, in some other embodiments, the guide rail 650 may also be set in the main frame 200, and the guide wheel 640 may be installed in the telescopic frame 300 by fasteners. The two work together to constrain the lifting trajectory of the telescopic frame 300.

[0099] The working principle of the ship unloader in this application is as follows:

[0100] I. Preliminary configuration process of the ship unloader:

[0101] The transport body 100, main frame 200, telescopic frame 300, and lifting mechanism are pre-installed. The transport body 100 is driven close to the cargo ship and then stopped. The telescopic frame 300 is raised to a suitable position within the main frame 200 so that the telescopic frame 300 is above the hatch opening, with the lowest point of the telescopic frame 300 higher than the top of the hatch, while maintaining a certain safe distance.

[0102] The telescopic frame 300 is propelled over the top of the cabin and into the interior via a lifting drive mechanism. The telescopic frame 300 remains vertical to the bottom of the cabin. Pressure sensors and anti-collision blocks are installed at the bottom of the telescopic frame 300. As the telescopic frame 300 descends and approaches the bottom of the cabin, it gradually decelerates and lands on the bottom of the cabin.

[0103] When the telescopic frame 300 descends to the bottom of the cabin, the control clutch 620 releases the output of the lifting motor 600 to the transmission component 610, thus allowing the lifting frame to be in a free lifting state. As the cargo in the cabin is continuously transported out, the cabin causes the telescopic frame 300 to float upwards. The telescopic frame 300 rises relative to the main frame 200. Therefore, the floating of the telescopic frame 300 will not affect the main frame 200, and thus will not cause the swaying of the transport body 100 or the change of the transport angle of the transport body 100.

[0104] When the telescopic frame 300 is lowered to the bottom of the cabin, it is connected to the transport aircraft 500 by fasteners, and the outlet of the transport aircraft 500 is aligned with the loading platform 310 on the telescopic frame 300.

[0105] II. Working process of the ship unloader:

[0106] The system includes a starting conveyor 500, a surrounding drive mechanism for the lifting mechanism, an intermediate conveyor 120, and a tail conveyor 140.

[0107] Packaged goods in the ship's hold are manually transferred to the conveyor. When a lifting unit 410 is detected approaching from below the loading platform 310, the drive stop 317 is put into the release state, and the goods enter the loading platform 310.

[0108] As the lifting unit 410 moves upward through the loading platform 310, multiple forks 411 of the lifting unit 410 pass through multiple loading bins 312 of the loading platform 310 to carry the goods on the multiple loading bins 312 upward.

[0109] During the downward movement of the lifting section 410 after it turns, the lifting section 410 passes through multiple loading cylinders 212 of the upper loading platform 210 from top to bottom, leaving the goods on the upper loading platform 210.

[0110] The goods are transported outward to the intermediate conveyor 120 by the rolling of multiple loading cylinders 212 on the loading platform 210. The intermediate conveyor 120 then transports the goods to the tail conveyor 140, and finally the goods fall to the ground near the exit end of the tail conveyor 140.
