Description

Technical Field

[0001] The present invention relates to the technical field of AGV construction, and in particular to an AGV for transporting steel plates. Background Art

[0002] With the rapid development of Industry 4.0 and intelligent manufacturing, the demand for automation, flexibility, and efficiency in steel transportation is becoming increasingly urgent. As a fundamental industrial material, steel is bulky, heavy, and prone to vibration. Traditional transportation methods present significant drawbacks: manual flatbed truck transportation relies on cranes for auxiliary loading and unloading, resulting in low efficiency and high labor costs. Furthermore, steel plates are prone to shifting or sliding during transportation, posing a significant safety hazard. Conventional magnetic AGVs lack dynamic stability control mechanisms, and inertia or road bumps during transportation can easily cause steel plates to vibrate, compromising positioning accuracy.

[0003] The current industry urgently needs an AGV equipment that combines efficient handling capabilities with dynamic and stable control to solve the safety, reliability and efficiency bottlenecks in steel transportation. Summary of the Invention

[0004] In light of this, the present invention provides an AGV for transporting steel plates to address significant drawbacks of traditional transportation methods: manual flatbed transport relies on crane-assisted loading and unloading, resulting in low efficiency and high labor costs. Furthermore, the steel plates are prone to shifting or sliding during transport, posing a significant safety hazard. Conventional magnetic AGVs lack dynamic stability control mechanisms, and inertia or road bumps during transport can easily cause the steel plates to wobble, affecting positioning accuracy.

[0005] In a first aspect, the present invention provides a steel plate transport AGV, comprising:

[0006] AGV car;

[0007] A support platform, the support platform is mounted on the AGV trolley, and a support portion is provided on the side of the support platform facing the steel plate;

[0008] a limiting structure, the limiting structure being mounted on the lower side of the supporting portion, the supporting portion and the limiting structure enclosing a accommodating space open downward;

[0009] A lifting structure is installed on the supporting platform, and the lifting structure can lift the steel plate into the accommodating space.

[0010] Beneficial effect: When the steel plate needs to be transported, the AGV trolley moves until the accommodation space is located directly above the steel plate. The lifting mechanism sucks the steel plate and moves the steel plate upward into the accommodation space. The AGV trolley is started, and the AGV trolley drives the steel plate toward the end point. Through the above arrangement, there is no need for manual transportation, and there is no need to rely on crane-assisted loading and unloading. The efficiency is high, and the steel plate is not easy to fall during transportation. By installing a limiting structure on the lower side of both ends of the support part, the steel plate is confined to the accommodation space by the limiting structure during the movement of the AGV trolley, and it can be stably controlled to prevent the steel plate from shaking due to inertia or road bumps during transportation, thereby improving the positioning accuracy of transportation.

[0011] In an optional embodiment, a plurality of limiting structures are provided, and the plurality of limiting structures are installed on the supporting portion at intervals along the first direction.

[0012] In an optional embodiment, the limiting structure includes two limiting frames, and the two limiting frames are arranged at intervals on both sides of the support portion along the second direction.

[0013] In an optional embodiment, the distance between the two limiting frames is equal to the width of the steel plate.

[0014] In an optional embodiment, the lifting structure includes:

[0015] a lifting mounting seat, the lifting mounting seat being fixed on the supporting portion;

[0016] A power member, the power member is mounted on the lifting mounting seat, and an output end of the power member faces the steel plate;

[0017] A guide assembly, the guide assembly being arranged at an output end of the power member;

[0018] A suction component is installed on the guide component, and the suction component is used to suck the steel plate.

[0019] In an optional embodiment, the lifting structure further comprises a guide rail support plate, wherein the guide rail support plate is vertically mounted on the lifting mounting seat;

[0020] The guide assembly comprises:

[0021] A linear guide rail, the linear guide rail being vertically mounted on the guide rail support plate;

[0022] A lifting plate is installed on the power component, a slider is installed on the linear guide rail, and the slider is connected to the lifting plate.

[0023] In an optional embodiment, the suction assembly includes:

[0024] A linear bearing is vertically arranged on the lifting plate, and a mounting hole is provided in the linear bearing;

[0025] a spring guide post, the spring guide post being installed in the mounting hole;

[0026] A floating plate, the floating plate being mounted on the lower end of the spring guide column, and an adsorption member being fixed on a side of the floating plate close to the steel plate;

[0027] A spring is sleeved on the linear bearing and the spring guide column between the floating plate and the lifting plate, one end of the spring abuts against the lifting plate, and the other end abuts against the floating plate.

[0028] In an optional embodiment, the adsorption member is an electromagnet.

[0029] Beneficial Effects: When a steel plate needs to be picked up, the power unit's output pushes the horizontal plate of the lifting plate downward. The vertical plate of the lifting plate, via a slider, moves vertically downward along a linear guide, driving the floating plate and electromagnet toward the plate. When the electromagnet contacts the plate, the spring is compressed, causing the floating plate to float relative to the lifting plate, ensuring full contact between the electromagnet and the plate's surface. The electromagnet is then energized to attract the plate, and the power unit's output retracts, pulling the lifting plate upward along the linear guide until it stops at the preset position within the holding space. As the floating plate ascends with the lifting plate via spring guides and linear bearings, the spring provides continuous downward pressure, preventing the plate from swaying and falling. The floating design of the spring and floating plate allows the electromagnet to automatically adjust upon contact with the plate, adapting to uneven surfaces and ensuring reliable suction. The linear guide and slider form a guide assembly that constrains the lifting plate's trajectory, preventing the plate from shifting during lifting. The linear bearings, mounting holes, and spring guides also provide a reliable grip. Using electromagnets to directly attract the plate replaces traditional overhead cranes for assisted loading and unloading, improving automation efficiency.

[0030] In an optional embodiment, the steel plate transport AGV further includes a protective cover, which is installed on the supporting part corresponding to the lifting structure.

[0031] In an optional embodiment, the blocking structure includes: a driving assembly and a blocking block, the driving assembly is mounted on the limiting frame, and the blocking block is mounted at the output end of the driving assembly.

[0032] Beneficial Effect: Before and during the lifting mechanism's process of moving the steel plate into the accommodation space, the blocking block is in its initial, back-up position, located above the horizontal bars of the limit frame. In this position, the blocking block vertically overlaps the bars, preventing the steel plate from entering the accommodation space. When the lifting mechanism raises the steel plate to the set height, the blocking action is triggered, and the rotary motor starts. The reducer receives power from the motor, reducing speed and increasing torque, driving the output end to rotate. The blocking block rotates with the output end of the drive assembly, rotating from the back-up position to the horizontal position, locking under the steel plate to form a physical barrier. With this arrangement, the blocking block immediately rotates into place after the steel plate is lifted, directly and mechanically preventing the steel plate from sliding downward. The L-shaped blocking mount integrates the drive assembly, ensuring overall rigidity. The reducer, coupled with the rotary motor, provides high torque output, ensuring the blocking block can withstand the inertial impact of the steel plate. The electromagnetic attraction of the blocking structure and the lifting mechanism provides a double safeguard, mitigating the risk of the block falling due to sudden power outages or shaking during transportation.

[0045] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0046] With the rapid development of Industry 4.0 and intelligent manufacturing, the demand for automation, flexibility, and efficiency in steel transportation is increasingly urgent. As a fundamental industrial material, steel is bulky, heavy, and prone to vibration. Traditional transportation methods present significant drawbacks: manual flatbed truck transportation relies on cranes for auxiliary loading and unloading, resulting in low efficiency and high labor costs. Furthermore, steel plates are prone to shifting or sliding during transportation, posing a significant safety hazard. Conventional magnetic AGVs lack dynamic stability control mechanisms, and inertia or road bumps during transportation can easily cause steel plates to vibrate, compromising positioning accuracy.

[0047] The current industry urgently needs an AGV equipment that combines efficient handling capabilities with dynamic and stable control to solve the safety, reliability and efficiency bottlenecks in steel transportation.

[0048] In order to solve the above technical problems, the following Figures 1 to 4 , describing embodiments of the present invention.

[0049] According to an embodiment of the present invention, on the one hand, a steel plate transport AGV is provided, comprising: an AGV trolley 1, a support platform 2, a limiting structure and a lifting structure 4.

[0050] The support platform 2 is a frame, fixed to the top surface of the AGV trolley 1 via pins. A support portion 21 protrudes from the side of the support platform 2 that faces the steel plate. The support portion 21 is generally a rectangular frame. Limiting structures are mounted on the undersides of both ends of the support portion 21. Together, the support portion 21 and the limiting structures form a downwardly open accommodation space. The lifting structure 4 is mounted on the support portion 21 directly above the accommodation space.

[0051] When the steel plate needs to be transported, the AGV trolley 1 moves until the storage space is directly above the steel plate. The lifting mechanism sucks the steel plate and moves the steel plate upward into the storage space. The AGV trolley 1 is started, and the AGV trolley 1 drives the steel plate toward the end point. Through the above arrangement, there is no need for manual transportation, and there is no need to rely on crane-assisted loading and unloading. The efficiency is high, and the steel plate is not easy to fall during transportation. By installing a limiting structure on the lower side of both ends of the support part 21, during the movement of the AGV trolley 1, the steel plate is restricted in the storage space by the limiting structure, which can be stably controlled to prevent the steel plate from shaking due to inertia or road bumps during transportation, thereby improving the positioning accuracy of transportation.

[0052] There are several limiting structures, which are installed on the support part 21 at intervals along the first direction. In this embodiment, there are two limiting structures, which are installed at intervals along the first direction at both ends of the support part 21. The specific structure of one of the limiting structures is described as follows: the limiting mechanism includes two limiting frames 3, which are installed at intervals on both sides of the support part 21 along a second direction perpendicular to the first direction. The first direction in this embodiment is the length direction of the steel plate. By setting two limiting structures to limit the two ends of the steel plate respectively, when the steel plate is lifted into the accommodation space by the lifting structure 4, the two limiting frames 3 are located on both sides of the steel plate, thereby limiting the steel plate and stably controlling it, preventing the steel plate from shaking due to inertia or road bumps during transportation, and improving the positioning accuracy of transportation. The distance between the two limiting frames 3 is equal to the width of the steel plate, or the distance between the two limiting frames 3 is slightly larger than the width of the steel plate. Avoid situations where the gap between the two limiting frames 3 is too narrow so that the steel plate cannot enter the accommodation space, or too wide so that the steel plate cannot be limited. Figure 1 The arrow A is the first direction, and the arrow B is the second direction.

[0053] A lifting structure 4 is mounted on a support portion 21. The specific structure of the lifting structure 4 is described using one example. The lifting structure 4 comprises a lifting mount 41, a power member 42, a guide assembly 43, a suction assembly 44, and a guide rail support plate 45. The two sides of the lifting mount 41 are fixed to the support portion 21. The guide rail support plate 45 is vertically fixed to the lifting mount 41. A mounting base for the power member 42 is mounted in the center below the lifting mount 41. The power member 42 is an electric cylinder. The fixed end of the power member 42 is fixed to the mounting base of the power member 42 via a pin, and the output end of the power member 42 faces downward. The guide assembly 43 comprises a linear guide rail 431 and a lifting plate 432. The two linear guide rails 431 are vertically mounted at intervals on the side of the guide rail support plate 45 near the power element 42. A slider is mounted on the linear guide rail 431. The lifting plate 432 is L-shaped, consisting of a vertical plate and a horizontal plate connected vertically. The horizontal plate of the lifting plate 432 is mounted on the output end of the power element 42, and the vertical plate of the lifting plate 432 is mounted on the slider. The suction assembly 44 comprises a linear bearing 441, a spring guide column 442, and a floating plate 443. The linear bearing 441 is fixed on the horizontal plate in the lifting plate 432. The linear bearing 441 runs through the lifting plate 432, and its two ends are respectively located at the upper and lower sides of the horizontal plate in the lifting plate 432. A mounting hole is vertically opened in the linear bearing 441, and the spring guide column 442 is installed in the mounting hole. The length of the spring guide column 442 is greater than the length of the mounting hole. A shaft retaining ring is installed at both ends of the spring guide column 442. The outer diameter of the upper shaft retaining ring is greater than the inner diameter of the mounting hole to prevent it from falling off from the mounting hole. The floating plate 443 is installed under the spring guide column 442. At the end, after the lower end of the spring guide column 442 passes through the floating plate 443, a shaft retaining ring is set at the lower end of the spring guide column 442, and a screw is used to pass through the shaft retaining ring and the floating plate 443 to fix the floating plate and the spring guide column. An adsorption part 444 is fixed on the side of the floating plate 443 close to the steel plate. The adsorption part 444 is an electromagnet. The spring 445 is mounted on the linear bearing 441 and the spring guide column 442 between the floating plate 443 and the lifting plate 432. One end of the spring 445 abuts against the lifting plate 432, and the other end abuts against the floating plate 443.

[0054] When the steel plate needs to be picked up, the output end of power element 42 pushes downward on the horizontal plate of lifting plate 432. The vertical plate of lifting plate 432 moves vertically downward along linear guide 431 via a slider, driving floating plate 443 and the electromagnet toward the steel plate. When the electromagnet contacts the steel plate, spring 445 is compressed, causing floating plate 443 to float relative to lifting plate 432, ensuring that the electromagnet is in full contact with the steel plate surface. The electromagnet is then energized to attract the steel plate. The output end of power element 42 retracts, pulling lifting plate 432 upward along linear guide 431 until the steel plate stops at the preset position within the receiving space. As floating plate 443 moves upward with lifting plate 432 via spring guide post 442 and linear bearing 441, spring 445 continuously provides downward pressure, preventing the steel plate from swaying and falling off. This floating design of spring 445 and floating plate 443 allows the electromagnet to automatically adjust to uneven surfaces when in contact with the steel plate, ensuring reliable suction. The guide assembly 43, consisting of a linear guide rail 431 and a slider, constrains the movement trajectory of the lifting plate 432 to prevent the steel plate from shifting during lifting. At the same time, the linear bearing 441, mounting holes, and spring guide pillars 442 use electromagnets to directly absorb the steel plate, replacing traditional overhead cranes to assist in loading and unloading, thereby improving automation efficiency.

[0055] In one embodiment, the blocking structure 6 includes a drive assembly 61 and a blocking block 62. The drive assembly 61 is mounted on the limiting frame 3. An L-shaped blocking mounting base is mounted on the limiting frame 3. The vertical plate of the blocking mounting base is fixed to the limiting frame 3. The horizontal plate of the blocking mounting base is mounted above the vertical plate of the blocking mounting base, and the horizontal plate of the blocking mounting base is bent inward. The drive assembly 61 includes a rotary motor and a reducer. The rotary motor and reducer are mounted on the blocking mounting base. The input end of the reducer is connected to the output shaft of the rotary motor. The blocking block 62 is mounted on the output end of the drive assembly 61 and is located between the horizontal plate and the vertical plate of the blocking mounting base.

[0056] Before and during the process of the lifting structure 4 moving the steel plate into the accommodation space, the blocking block 62 is in its initial, avoidance position, located above the horizontal rod of the limit frame 3. In this avoidance position, the blocking block 62 vertically overlaps with the horizontal rod of the limit frame 3, preventing the steel plate from entering the accommodation space. When the lifting mechanism raises the steel plate to the set height, the blocking action is triggered, and the rotary motor starts. The reducer receives power from the motor, reducing the speed and increasing the torque, driving the output end to rotate. The blocking block 62 rotates with the output end of the drive assembly 61, rotating from the avoidance position to the horizontal position, locking under the steel plate to form a physical barrier. With this arrangement, the blocking block 62 immediately rotates into place after the steel plate is lifted, directly mechanically preventing the steel plate from sliding downward. The L-shaped blocking mount integrates the drive assembly 61 to ensure overall rigidity. The reducer is matched with the rotary motor to provide high torque output, ensuring that the blocking block 62 can withstand the inertial impact of the steel plate. The blocking structure 6 and the lifting mechanism's electromagnetic attraction provide a double guarantee, eliminating the risk of falling due to sudden power outages or shaking during transportation.

[0057] In one embodiment, the steel plate transport AGV further includes a protective cover 5 , which is installed on the support portion 21 corresponding to the lifting structure 4 to provide protection and a certain degree of dust prevention.
