Description

Technical Field

[0001] This invention relates to the field of cargo transportation technology, and in particular to an automated cargo transport machine for ports. Background Technology

[0002] With the expansion of global trade and the increasing demand for intelligent port logistics, the transfer and storage of bulk cargo, containers and precision equipment need to be handled efficiently and with low damage in the process of surging port cargo throughput and rising labor costs. This requires the use of transport aircraft.

[0003] In practical use, similar transport aircraft still have many shortcomings. For example, traditional transport aircraft mostly use fixed conveyor belts or intermittent lifting equipment, requiring manual intervention in loading, unloading, turning, and route planning, resulting in fragmented operation processes. At the same time, traditional transport aircraft lack dynamic protection mechanisms for cargo during transfer. For instance, containers may suffer surface wear due to shaking and collisions during lifting, and precision instruments may be displaced or fall due to the inertial impact of the conveyor belt, causing economic losses. Therefore, it is necessary to design an automated port cargo transport aircraft. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an automated port cargo transport machine.

[0005] This invention is achieved using the following technical solution: an automated port cargo transport machine, comprising a transport component, the transport component including a main frame, a load-bearing conveyor roller rotatably connected inside the main frame, a conveyor belt sleeved on the outer surface of the load-bearing conveyor roller, cargo guide plates fixedly connected to the inner wall of the main frame on both sides of the conveyor belt, and casters rotatably connected inside the bottom of the main frame, and further comprising:

[0006] A lifting assembly, the lifting assembly including a fixed base plate fixedly connected to the top of the main frame, and a winch fixedly connected to the top of the fixed base plate via a winch bracket;

[0007] An adjustment assembly, comprising a first rotating rod and a second rotating rod rotatably connected to the inner wall of the main frame, wherein the first rotating rod and the second rotating rod are connected by a connecting chain;

[0008] The collection assembly includes a collection rack slidably installed inside the main frame, a hanging connecting plate fixedly connected to the top of the collection rack, a lifting wire rope fixedly connected to the top of the hanging connecting plate, a cargo clamping plate slidably installed inside the collection rack, and a linear guide groove provided inside the collection rack.

[0009] The discharge assembly includes a discharge cylinder fixedly connected to the rear end of the main frame. The output end of the discharge cylinder passes through the main frame and is fixedly connected to a push block, which is located at the rear end of the collection rack.

[0010] As a further improvement to the above solution, a servo motor is fixedly connected to the outer surface of the main frame, and the output end of the servo motor is fixedly connected to a power transmission shaft through the main frame. A conveyor belt is sleeved on the outer surface of the power transmission shaft.

[0011] The above technical solution directly drives the conveyor belt to rotate via a servo motor, replacing the traditional mechanical transmission method. This enables precise control and dynamic adjustment of the conveyor belt speed. The motor speed can be adjusted according to the weight of the goods or the conveying requirements, avoiding goods slipping or impact due to inertia, and improving the stability and adaptability of transportation.

[0012] As a further improvement to the above solution, a base bracket is fixedly connected to the outer surface of the main frame, a fixed base plate is fixedly connected to the top of the base bracket, a mounting frame is fixedly connected to the top of the fixed base plate, and a winch is fixedly connected to the top of the mounting frame via a winch bracket, with a lifting wire rope sleeved at the output end of the winch.

[0013] Through the above technical solution, the layered design of the base bracket and the mounting frame fixes the winch at a high position on the top of the main frame, optimizes the tension direction of the lifting wire rope, and reduces swaying deviation during suspension. At the same time, the rigid connection of the winch bracket ensures the stability of the winch during operation and avoids the risk of the lifting wire rope loosening or breaking due to vibration.

[0014] As a further improvement to the above solution, a first rotating seat is rotatably connected inside the main frame, a first sprocket is fixedly connected to the outer surface of the first rotating seat, and a first rotating rod is fixedly connected to the outer surface of the first sprocket.

[0015] Through the above technical solution, the fixed connection between the first sprocket and the first rotating rod transmits the rotational power to the connecting chain through chain drive, realizing multi-axis synchronous drive, simplifying the complex structure of traditional gear sets, reducing equipment failure rate, and ensuring the uniformity of force transmission through sprocket meshing, avoiding single-point overload.

[0016] As a further improvement to the above solution, a first force-bearing gear is fixedly connected to the outer surface of the first rotating rod, and the first force-bearing gear is connected to the main frame through a connecting seat. The side of the first rotating rod away from the first rotating seat is rotatably connected to the inside of the connecting seat.

[0017] Through the above technical solution, the first force-bearing gear is fixed to the main frame through the connecting seat. When bearing the high load when the collection frame descends, the radial pressure of the gear is dispersed, preventing the gear shaft from deforming or breaking. In addition, the rotating bearing design of the connecting seat reduces friction loss and extends the service life of the transmission components.

[0018] As a further improvement to the above solution, a second rotating seat is provided on the top of the first rotating seat and rotatably connected to the inner wall of the main frame. A second sprocket is fixedly connected to the outer surface of the second rotating seat, and a second rotating rod is fixedly connected to the outer surface of the second sprocket. The second sprocket and the first sprocket are connected by a connecting chain.

[0019] Through the above technical solution, the second sprocket is linked to the first sprocket by a connecting chain, which ensures the rotational synchronization of the first rotating rod and the second rotating rod, balances the force difference of the two transmission systems, avoids the equipment tilting due to excessive load on one side, and improves the operational stability under heavy load conditions.

[0020] As a further improvement to the above solution, a first drive rack is fixedly connected to the outer surface of the collection rack, the first drive rack meshes with a first force-bearing gear, a limit baffle is fixedly connected to the outer surface of the collection rack, a linear guide rod is fixedly connected to the center of the limit baffle, and a movable seat is slidably connected to the outer surface of the linear guide rod.

[0021] Through the above technical solution, the meshing drive of the first drive rack and the first force-bearing gear, combined with the limiting effect of the limiting baffle and the linear guide rod, constrains the descent trajectory of the collection frame and prevents it from deviating laterally. The low-friction sliding sleeve design of the linear guide rod further reduces the motion resistance and ensures the smoothness and controllability of the descent process of the collection frame.

[0022] As a further improvement to the above solution, a second drive rack is fixedly connected to one side of the outer surface of the movable seat, and the second drive rack meshes with a second force-bearing gear. A cargo clamping plate is fixedly connected to the side of the outer surface of the movable seat away from the second drive rack. The cargo clamping plate is slidably installed inside the linear guide groove. A buffer pulley is rotatably connected to the bottom of the collection rack.

[0023] Through the above technical solution, the meshing drive of the second drive rack and the second force-bearing gear pushes the moving seat down along the linear guide rod, causing the cargo clamping plate to move closer synchronously in the linear guide groove, realizing the adaptive clamping of the cargo. The mechanical linkage replaces manual fixing, reducing the complexity of operation. At the same time, the uniform distribution of clamping force avoids local pressure damage to the cargo.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] This invention forms a "transportation to collection" linkage system through the guiding cooperation of the conveyor belt and the cargo guide plate, the flexible steering of the moving wheels, and the suspension control of the collection rack by the winch. The conveyor belt achieves continuous transportation under the drive of the servo motor. With the limiting effect of the cargo guide plate, it ensures that the cargo moves stably towards the collection component. The winch initially suspends the collection rack at a high position. Combined with the low-friction transition design of the buffer sliding wheel, the cargo slides smoothly into the collection rack and avoids collision damage. Through standardized conveying path and adaptive collection method, the transfer efficiency of port logistics is significantly improved. At the same time, the high suspension and buffer sliding wheel transition structure reduces the risk of mechanical damage to the cargo. It is especially suitable for fragile or high surface precision requirements of cargo.

[0026] This invention utilizes a two-stage meshing transmission—one with a first driving rack and a first force-bearing gear, and the other with a second driving rack and a second force-bearing gear—combined with synchronous linkage of a connecting chain, to drive the collection rack to descend and the moving seat to clamp. During descent, the first and second rotating rods rotate in the same direction via the connecting chain, achieving mechanical balance. The moving seat slides vertically down the linear guide rod, pushing the cargo clamping plate to synchronously approach within the linear guide groove, thus clamping and fixing the cargo. The precise meshing of the gears and racks, along with the synchronous chain transmission, ensures the stability of the collection rack's descent, preventing uneven loading due to varying cargo weight. Simultaneously, the linkage clamping mechanism of the cargo clamping plate effectively prevents cargo displacement or tipping, providing dual safety guarantees for subsequent transportation or storage and enhancing the equipment's versatility and reliability.

[0038] Example:

[0039] Please combine Figure 1-8 An automated port cargo transport machine according to this embodiment includes a transport component 1. The transport component 1 includes a main frame 101. A load-bearing conveyor roller 104 is rotatably connected inside the main frame 101. A conveyor belt 105 is sleeved on the outer surface of the load-bearing conveyor roller 104. Cargo guide plates 106 are fixedly connected to the inner wall of the main frame 101 on both sides of the conveyor belt 105. A movable wheel 107 is rotatably connected to the bottom of the main frame 101. The machine also includes:

[0040] The lifting assembly 2 includes a fixed base plate 202 fixedly connected to the top of the main frame 101, and a winch 205 is fixedly connected to the top of the fixed base plate 202 via a winch bracket 204.

[0042] The collection component 4 includes a collection rack 401 that is slidably installed inside the main frame 101. A hanging connection plate 410 is fixedly connected to the top of the collection rack 401, and a lifting wire rope 206 is fixedly connected to the top of the hanging connection plate 410. A cargo clamping plate 407 is slidably installed inside the collection rack 401, and a linear guide groove 408 is provided inside the collection rack 401.

[0043] The discharge assembly 5 includes a discharge cylinder 501 fixedly connected to the rear end of the main frame 101. The output end of the discharge cylinder 501 passes through the main frame 101 and is fixedly connected to a push block 502, which is located at the rear end of the collection rack 401.

[0044] A servo motor 102 is fixedly connected to the outer surface of the main frame 101. The output end of the servo motor 102 passes through the main frame 101 and is fixedly connected to a power transmission shaft 103. A conveyor belt 105 is sleeved on the outer surface of the power transmission shaft 103.

[0045] After the servo motor 102 is started, the power transmission shaft 103 at its output end drives the conveyor belt 105 and the carrying conveyor roller 104 to rotate synchronously, forming continuous conveying power. Under the guidance of the cargo guide plate 106, the conveyor belt 105 stably conveys the cargo to the collection component 4.

[0046] A base bracket 201 is fixedly connected to the outer surface of the main frame 101. A fixed base plate 202 is fixedly connected to the top of the base bracket 201. A mounting bracket 203 is fixedly connected to the top of the fixed base plate 202. A winch 205 is fixedly connected to the top of the mounting bracket 203 via a winch bracket 204. A lifting wire rope 206 is sleeved at the output end of the winch 205.

[0047] The main frame 101 is rotatably connected to a first rotating seat 301. A first sprocket 302 is fixedly connected to the outer surface of the first rotating seat 301. A first rotating rod 303 is fixedly connected to the outer surface of the first sprocket 302.

[0048] In its initial state, the winch 205 suspends the collection rack 401 at a high position by lifting the wire rope 206, providing sufficient vertical space for the goods and avoiding collisions with the collection rack 401 during transportation. This design effectively reduces the risk of mechanical damage when the goods are stacked.

[0049] A first force-bearing gear 304 is fixedly connected to the outer surface of the first rotating rod 303. The first force-bearing gear 304 is connected to the main frame 101 through a connecting seat 305. The side of the first rotating rod 303 away from the first rotating seat 301 is rotatably connected to the inside of the connecting seat 305.

[0050] The top of the first rotating seat 301 is provided with a second rotating seat 307 rotatably connected to the inner wall of the main frame 101. A second sprocket 308 is fixedly connected to the outer surface of the second rotating seat 307. A second rotating rod 309 is fixedly connected to the outer surface of the second sprocket 308. The second sprocket 308 and the first sprocket 302 are connected by a connecting chain 306.

[0051] The first drive rack 402 on the outer surface of the collection rack 401 meshes with the first force-bearing gear 304, driving the first rotating rod 303 to rotate. Through the synchronous transmission of the connecting chain 306, the second rotating rod 309 rotates in the same direction as the first rotating rod 303, forming a stable force transmission system.

[0052] A first drive rack 402 is fixedly connected to the outer surface of the collection rack 401. The first drive rack 402 meshes with the first force-bearing gear 304. A limit baffle 403 is fixedly connected to the outer surface of the collection rack 401. A linear guide rod 404 is fixedly connected to the center of the limit baffle 403. A movable seat 405 is slidably connected to the outer surface of the linear guide rod 404.

[0053] The cargo clamping plates 407 on both sides of the movable seat 405 approach synchronously under the limit of the linear guide groove 408, clamping the cargo in the collection rack 401 to prevent it from shifting or tipping over during subsequent transportation or storage. The combined design of the limiting baffle 403 and the linear guide rod 404 ensures the stability of the descent trajectory of the movable seat 405 and avoids the problem of uneven load caused by uneven weight of cargo.

[0054] A second drive rack 406 is fixedly connected to one side of the outer surface of the movable seat 405. The second drive rack 406 meshes with the second force-bearing gear 310. A cargo clamping plate 407 is fixedly connected to the side of the outer surface of the movable seat 405 away from the second drive rack 406. The cargo clamping plate 407 is slidably installed inside the linear guide groove 408. A buffer pulley 409 is rotatably connected to the bottom of the collection rack 401.

[0055] The implementation principle of an automated port cargo transport machine in this embodiment is as follows: the cargo to be transported is placed on the surface of the conveyor belt 105. Driven by the moving wheels 107, the transport component 1 can move along a predetermined path to the target area. After the servo motor 102 is started, the power transmission shaft 103 at its output end drives the conveyor belt 105 and the carrying conveyor roller 104 to rotate synchronously, forming continuous conveying power. Under the guidance of the cargo guide plate 106, the conveyor belt 105 stably transports the cargo towards the collection component 4. During this process, the main frame 101 can achieve flexible steering through the moving wheels 107. The efficient handling across multiple angles and regions significantly improves the transfer efficiency of port logistics. When the goods are transported to the collection rack 401 of the collection component 4, the buffer sliding wheel 409 inside the collection rack 401 forms a smooth transition surface through the inclined design, reducing the frictional resistance between the goods and the collection rack 401 and ensuring that the goods slide smoothly into the collection rack 401. In the initial state, the winch 205 suspends the collection rack 401 at a high position by lifting the wire rope 206, providing sufficient vertical space for the goods and avoiding collisions with the collection rack 401 during transportation. This design effectively reduces the risk of mechanical damage when the goods are piled up.

[0056] After the goods enter the collection rack 401, the winch 205 gradually releases the lifting wire rope 206. Under the combined action of its own weight and the weight of the goods, the collection rack 401 slowly descends along the main frame 101. At this time, the first drive rack 402 on the outer surface of the collection rack 401 meshes with the first force-bearing gear 304, driving the first rotating rod 303 to rotate. Through the synchronous transmission of the connecting chain 306, the second rotating rod 309 rotates in the same direction as the first rotating rod 303, forming a stable force transmission system. As the collection rack 401 descends, the second drive rack 406 on its outer surface meshes with the second force-bearing gear 310, driving the moving seat 405 to slide vertically down the linear guide rod 404. The goods clamping plates 407 on both sides of the moving seat 405 are in the linear guide groove. The limit switch 408 moves synchronously closer to clamp the goods in the collection rack 401, preventing them from shifting or tipping over during subsequent transportation or storage. The combined design of the limit baffle 403 and the linear guide rod 404 ensures the stability of the descent trajectory of the moving seat 405 and avoids the problem of uneven load caused by uneven weight of goods. When the lifting component 2 lifts the collection rack 401 to rise, and ensures that the goods are in the fixed state of the goods clamping plate 407, the push block 502 is driven by the discharge cylinder 501 to slide. At this time, the push block 502 will resist the goods and push them. The rollers installed in the collection rack 401 push the goods to the conveyor belt 105, and the operation of the transport component 1 transports the goods to the storage area.

[0057] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
