Description

Technical Field

[0001] This utility model relates to the field of AGV guided vehicles, and in particular to a high-load-bearing automatic AGV guided vehicle. Background Technology

[0002] Against the backdrop of rapid development in industry and intelligent manufacturing, Automated Guided Vehicles (AGVs) have become core equipment in modern logistics and manufacturing, widely used for material handling in factories, warehouses, and other scenarios. Their technological development has evolved from fixed-path guidance to flexible autonomous navigation, with core technologies encompassing navigation systems, control systems, and drive systems. Heavy-duty AGVs, as an important branch, are primarily used for handling ton-sized goods, suitable for scenarios with high load-bearing capacity requirements, such as automobile manufacturing, logistics warehousing, and steel smelting.

[0003] Traditional heavy-duty AGVs have a fixed platform area. When faced with extra-wide, extra-long, or irregularly sized materials, they lack an expandable load-bearing structure, which can easily lead to materials exceeding the platform's edge, causing tilting or falling risks. Furthermore, if materials are misplaced or encounter uneven ground while the heavy-duty AGV is in motion, unilateral overload can easily occur, leading to accelerated wear on the drive wheels or vehicle rollover. Utility Model Content

[0004] The main purpose of this invention is to provide a high-load-bearing automatic AGV guided vehicle, which can effectively solve the problem of low operational stability of traditional heavy-duty AGVs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] Preferably, the guide module includes a support frame three, the housing is fixedly connected to the support frame three, and the housing is fixedly connected to a support frame four and a support frame two on the left and right sides of the support frame three, respectively.

[0013] 1. This utility model provides a high-load-bearing automatic AGV guided vehicle. The drive module of the guided vehicle is fixed at the middle position of the bottom of the loading platform. Together with the front guide module and the rear auxiliary wheel, the overall center of gravity is concentrated in the middle of the vehicle body, reducing the center of gravity offset.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1As shown, this utility model provides a high-load-bearing automatic AGV (Automated Guided Vehicle), including a housing 1. A loading platform 10 is slidably connected to the top of the housing 1. An anti-slip mat 9 is fixedly connected to the top of the loading platform 10. Guardrails 7 are rotatably connected to both the left and right sides of the loading platform 10 and the anti-slip mat 9. An electric push rod 8, the power source of the guardrail 7, is rotatably connected to the outer side of the guardrail 7. The other end of the electric push rod 8 is rotatably connected to the housing 1. Guide rods 6 are rotatably connected to both the front and rear sides of the electric push rod 8 on the guardrail 7. A sleeve 5 is slidably connected to the outer side of the guide rod 6. The side of the sleeve 5 away from the guide rod 6 is rotatably connected to the housing 1. A drive module 4 is fixedly connected to the bottom of the loading platform 10 on the housing 1. A [missing information - likely a device or component] is fixedly connected to the front of the drive module 4 on the housing 1. The guide module 2 and the housing 1 are equipped with auxiliary wheels behind the drive module 4. When the material to be transported is placed on the anti-slip mat 9, the anti-slip mat 9 prevents the material from sliding due to inertia when the AGV starts, stops suddenly, or turns. At the same time, the guardrails 7 on the left and right sides of the loading platform 10 are in a vertical state, which can directly prevent the material from falling from the edge of the platform, forming basic protection. The electric push rod 8 rotatably connected to the outside of the guardrail 7 is in a retracted state, and the guide rods 6 on its front and rear sides are partially retracted into the sleeve 5, providing initial support for the guardrail 7. The housing 1 serves as the foundation of the overall structure. The drive module 4 fixed in the middle of its bottom provides reserve power for subsequent driving. The guide module 2 fixed in front and the auxiliary wheels set at the rear together ensure the stability of the AGV when driving and turning.

[0023] like Figure 2 As shown, this utility model provides a high-load-bearing automatic AGV guided vehicle. A shock absorber 12 is fixedly connected to the bottom of the cargo platform 10, and a support frame 11 is fixedly connected to the other end of the shock absorber 12. The support frame 11 is fixedly connected to the shell 1. When the AGV travels on uneven ground, the vibration generated by the ground bumps will first be transmitted to the shell 1, and then transmitted to the shock absorber 12 through the support frame 11. The shock absorber 12 absorbs and weakens the vibration energy through the deformation and damping effect of the internal elastic element, avoiding the vibration from being directly transmitted to the material on the cargo platform 10, reducing material damage, and at the same time reducing the impact of vibration on the connection structure between the cargo platform 10 and the shell 1, extending the service life of the components.

[0024] like Figure 3As shown, this utility model provides a high-load-bearing automatic AGV (Automated Guided Vehicle). A battery compartment 3 is fixedly connected to the housing 1 below the loading platform 10. The drive module 4 includes a transmission rod 41, which is rotatably connected to the housing 1. Drive wheels 43 are fixedly connected to both sides of the transmission rod 41. A driven pulley 42 is fixedly connected between the two drive wheels 43. A fixing frame 45 is fixedly connected to the housing 1 in front of the transmission rod 41. A driving pulley 44 is rotatably connected to the fixing frame 45 in front of the driven pulley 42. 44 and driven pulley 42 are driven by a belt. A motor that provides power to drive pulley 44 is fixedly connected to the fixed frame 45. When the motor on the fixed frame 45 is started, the motor output shaft drives the drive pulley 44 fixed to it to rotate. Then the drive pulley 44 drives the driven pulley 42 to rotate through the belt, thereby transmitting power to the transmission rod 41. When the transmission rod 41 rotates, it synchronously drives the two drive wheels 43 to rotate, so that the drive wheels 43 contact the ground to generate friction, thereby converting the rotational power into the AGV's forward or backward linear travel power.

[0025] like Figure 4 As shown, this utility model provides a high-load-bearing automatic AGV guided vehicle. The guide module 2 includes a support frame 3 22. The housing 1 is fixedly connected to the support frame 3 22. The housing 1 is fixedly connected to the support frame 4 23 and the support frame 21 on the left and right sides of the support frame 3 22, respectively. The support frame 4 23 and the support frame 21 can withstand the lateral force transmitted by the guide wheel 24 when the AGV turns, and at the same time provide a stable foundation for the installation and power output of the electric push rod 210.

[0026] like Figure 5 As shown, this utility model provides a high-load-bearing automatic AGV guided vehicle. A rotating seat 26 is rotatably connected to the lower part of support frame 21, and a rotating seat 28 is rotatably connected to the lower part of support frame 4 23. Guide wheels 24 are rotatably connected to the outer sides of both rotating seat 1 26 and rotating seat 28. Support frame 5 25 is fixedly connected to the front of both rotating seat 1 26 and rotating seat 28. A linkage rod 27 is rotatably connected between the two support frames 5 25. A support frame 6 29 is fixedly connected to the rear of rotating seat 28. The inner side of support frame six 29 is rotatably connected to electric push rod two 210, which is the power source of the support frame. The other end of electric push rod two 210 is rotatably connected to support frame three 22. When the AGV needs to change direction, electric push rod two 210 pushes rotating seat two 28 to rotate through support frame six 29, thereby changing the guiding direction of guide wheel 24 on the outer side of rotating seat two 28. At the same time, rotating seat two 28 and rotating seat one 26 form a parallel four-bar linkage through support frame five 25 and linkage rod 27, so that the two guide wheels 24 always remain parallel.

[0027] The working principle of this high-load-bearing automated AGV will be explained in detail below.

[0028] like Figure 1-5As shown, when materials are placed on the anti-slip mat 9 above the loading platform 10, the anti-slip mat 9 increases the friction between the materials and the platform, preventing the materials from sliding due to inertia when the AGV starts, stops suddenly, or turns. Simultaneously, the loading platform 10 is connected to the support frame 11 via the shock absorber 12 at the bottom. The support frame 11 is fixed to the housing 1. The shock absorber 12 buffers vibrations caused by ground bumps, reducing damage to heavy materials and minimizing the impact on the vehicle structure. When the material size exceeds the fixed area of ​​the loading platform 10, the electric gate on the outside of the guardrail 7 is activated. The electric push rod 8 is rotatably connected at one end to the housing 1 and at the other end to the guardrail 7. When the electric push rod 8 extends, it causes the guardrail 7 to rotate outward around the connection point of the loading platform 10 until the guardrail 7 and the loading platform 10 are level, forming an expanded bearing surface. During this process, the guide rods 6 rotatably connected to the front and rear sides of the guardrail 7 will slide synchronously along the inner side of the sleeve 5. When the guardrail 7 is completely flattened, the guide rods 6 are completely retracted into the sleeve 5, and the two form a rigid support structure, which enhances the bearing capacity of the guardrail 7, prevents heavy materials from crushing the guardrail 7, and prevents materials from falling off the platform. When the edge tilts and falls, the motor starts, driving the drive pulley 44, which is fixed on the fixed frame 45, to rotate. The drive pulley 44 forms a transmission engagement with the driven pulley 42 via a belt, and then drives the transmission rod 41 to rotate via the driven pulley 42. Because both ends of the transmission rod 41 are rotatably connected to the housing 1, and drive wheels 43 are fixedly connected to both its left and right sides, the rotation of the transmission rod 41 will synchronously drive the two drive wheels 43 to rotate. The drive wheels 43 generate friction with the ground, providing the AGV with forward or backward driving power, meeting the power requirements under heavy load conditions. The housing 1 is fixedly connected to the battery compartment 3 below the loading platform 10. The battery pack inside the battery compartment 3 provides continuous power to the motor, electric push rod 8, and electric push rod 210 for subsequent steering adjustment of the drive module 4. When the AGV needs to change its driving direction, the electric push rod 210 in the guide module 2 is activated. Because one end of the electric push rod 210 is rotatably connected to the support frame 3 22 and the other end is rotatably connected to the support frame 6 29, when the electric push rod 210 extends or shortens, it will push the rotating seat 2 28 to rotate around its connection point with the support frame 4 23.A guide wheel 24 is rotatably connected to the outer side of the rotating seat 28. Therefore, when the rotating seat 28 rotates, it will synchronously drive the guide wheel 24 to change its orientation, realizing the directional adjustment of a single guide wheel 24. A support frame 5 25 is fixedly connected to the front of both the rotating seat 1 26 and the rotating seat 28. A linkage rod 27 is rotatably connected between the two support frames 5 25, forming a parallel four-bar linkage: when the rotating seat 28 rotates, it will drive the linkage rod 27 to move through the support frame 5 25, and the linkage rod 27 will then drive the support frame 5 25 on the other side and the rotating seat 1 26 to rotate synchronously. The guide wheels 24 on the outer side of rotating seat 1 26 and the outer side of rotating seat 28 are kept parallel to ensure that the guide wheels 24 on both sides are in the same direction when the AGV turns, preventing the vehicle from veering off course. This, combined with the auxiliary wheels at the rear, further improves stability during turning. The drive module 4 is fixed to the center of the bottom of the loading platform 10. The housing 1 has a guide module 2 in front of the drive module 4 and auxiliary wheels behind it, concentrating the AGV's center of gravity in the middle of the vehicle, reducing center of gravity shift caused by material placement misalignment or unilateral overload.
