Description

Technical Field

[0001] This utility model relates to the field of industrial automation technology, specifically to a heavy-duty truck chassis handling AGV. Background Technology

[0002] In the heavy-duty truck manufacturing industry, the chassis is one of the most critical components in the entire vehicle production process, and its transfer needs are present at multiple stages of the production line. Currently, the transfer of truck chassis between different production lines mainly uses overhead cranes. Overhead crane transport utilizes overhead rails and lifting equipment installed within the factory to lift the chassis from one workstation to a designated location. The advantage of this method is that it can directly complete the horizontal and vertical movement of the chassis through lifting, without occupying ground space.

[0003] However, overhead crane lifting is limited by the structural layout of workshops and factories. In some factories, due to constraints in track layout, limited space, or complex lifting paths, effective lifting of the chassis is difficult. Furthermore, during long-distance lifting, the large size and heavy weight of the chassis make it prone to significant swaying at high altitudes, increasing instability. This not only reduces lifting efficiency but also poses significant safety hazards, such as the risk of equipment damage or personnel injury. Utility Model Content

[0004] The purpose of this invention is to provide a heavy-duty truck chassis handling AGV to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heavy-duty truck chassis handling AGV, comprising:

[0006] Vehicle body;

[0007] A first support mechanism is mounted on the vehicle body and is used to support the truck chassis.

[0008] The second support mechanism is installed on the vehicle body. The second support mechanism works in conjunction with the first support mechanism to support truck chassis of different sizes.

[0009] Preferably, the first support mechanism includes a first fixed shelf fixedly connected to one side of the top of the vehicle body.

[0010] Preferably, the second support mechanism includes two slide rails fixedly connected to the top of the vehicle body, the two slide rails being fixed on the side of the top of the vehicle body opposite to the first fixed shelf.

[0011] Preferably, a slider is slidably connected to the top of each of the two slide rails, and a second fixed shelf is fixedly connected to the top of the two sliders.

[0012] Preferably, an adjustable locking structure is provided on both sides of the second fixed shelf near the slider position.

[0013] Preferably, a laser obstacle avoidance radar is provided on the edge side of the vehicle body.

[0014] Preferably, a safety emergency stop switch and a three-color warning light are provided next to the second support mechanism on the vehicle body.

[0015] Preferably, two load-bearing wheels are respectively provided on both sides of the bottom of the vehicle body, and a shock-absorbing servo motor is provided next to each pair of load-bearing wheels.

[0016] Preferably, an RFID sensor is provided at the middle position of the bottom of the vehicle body, a magnetic navigation sensor is provided on one side of the RFID sensor on the vehicle body, and an automatic charging brush block is provided on the other side of the RFID sensor on the vehicle body.

[0017] Preferably, the shock-absorbing servo motor includes a spring-damping structure and a dual-axis rotary servo motor, used to maintain continuous contact between the load-bearing wheel and the ground.

[0018] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0019] This heavy-duty truck chassis transport AGV, through the setting of a first support mechanism and a second support mechanism, can adapt to the transport needs of truck chassis of different sizes. The slide rail and slider design of the second support mechanism allows for adjustable support spacing, further improving the AGV's versatility and applicability to various truck chassis models. The adjustable spacing locking structure of the second support mechanism ensures the chassis's stability during transport. Combined with the layout of the load-bearing wheels and shock-absorbing servo motors, it effectively reduces vibration and swaying during transport, improving the stability and safety of chassis transportation. The AGV is equipped with laser obstacle avoidance radar, three-color warning lights, and a safety emergency stop switch, enabling real-time monitoring of the surrounding environment and rapid response to emergencies, significantly improving the safety of equipment operation and avoiding obstacles. To prevent potential accidents, precise positioning is achieved through RFID and magnetic navigation sensors. Combined with the use of automatic charging devices, the AGV can automate the entire process of chassis handling, positioning, and standby operations, reducing manual intervention and lowering operating costs. Through the optimized design of the chassis support mechanism and the integration of functions of the vehicle body, the handling of heavy truck chassis no longer relies on overhead cranes, breaking free from the limitations of factory structure layout and adapting to complex production line arrangements. This improves the flexibility and efficiency of chassis transfer. The shock-absorbing servo motor adopts a spring shock-absorbing structure and a dual-axis rotating servo motor design to ensure continuous contact between the load-bearing wheels and the ground, improving the stability of driving force output and further enhancing the accuracy and reliability of the handling process.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-5 As shown, a heavy-duty truck chassis handling AGV includes a vehicle body 1; a first support mechanism 2, disposed on the vehicle body 1, for supporting the truck chassis; and a second support mechanism 3, disposed on the vehicle body 1, cooperating with the first support mechanism 2 to support truck chassis of different sizes.

[0028] The vehicle body 1, as the core structure of the entire device, provides overall load-bearing capacity and stability. The first support mechanism 2 is used for fixed-position truck chassis support, while the second support mechanism 3, through its adjustable design, adapts to truck chassis of different sizes, enabling the AGV to meet diverse usage needs. The combination of the two support mechanisms achieves stable handling of heavy-duty truck chassis. This embodiment can adapt to truck chassis of different sizes, providing greater operational flexibility, and the combined support structure improves the stability and reliability of the handling process.

[0029] The specific structure or materials of the first support mechanism 2 and the second support mechanism 3 can be adjusted. For example, a lighter alloy material can be used to improve convenience while maintaining their load-bearing capacity. In addition, the operational efficiency when supporting chassis of different sizes can be optimized by adjusting the way the two work together.

[0030] In one possible implementation, the first support mechanism 2 includes a first fixed rack 201 fixedly connected to one side of the top of the vehicle body 1. The first fixed rack 201 acts as a stable support platform, ensuring stable load-bearing capacity of the truck chassis during transport through its integrated fixed connection with the vehicle body 1. Using the fixed rack 201 as the first support mechanism not only simplifies the structural design but also enhances the stable support effect on standard-sized chassis, reducing the failure rate.

[0031] The design of the first fixed shelving unit 201 allows for the selection of different materials, such as carbon fiber or high-strength composite materials, to further enhance structural strength and reduce overall weight, depending on actual needs.

[0032] In one possible implementation, the second support mechanism 3 includes two slide rails 301 fixedly connected to the top of the vehicle body 1. The two slide rails 301 are fixed to the side of the top of the vehicle body 1 opposite to the first fixed rack 201. As a core component of the second support mechanism 3, the slide rails 301, through their arrangement on the vehicle body 1, achieve flexibility and adjustability of the support mechanism to adapt to the handling needs of chassis of different sizes. The design of the slide rails 301 enhances the flexibility of the support mechanism, enabling the equipment to adapt to various specifications of truck chassis and improving the versatility of the equipment.

[0033] The slide rail 301 can be replaced with other linear guide types, such as ball screw guides or magnetic levitation guides, to further optimize structural performance and service life.

[0034] In one possible implementation, a slider 302 is slidably connected to the top of each of the two slide rails 301, and a second fixed shelf 303 is fixedly connected to the top of the two sliders 302. The sliders 302 achieve an adjustable sliding function through the slide rails 301, thereby flexibly adjusting the position of the second fixed shelf 303 to suit the size and shape of the truck chassis for better support. The cooperation between the sliders 302 and the slide rails 301 significantly improves the adaptability of the second support mechanism while ensuring the smoothness and positioning accuracy of the sliding process.

[0035] The slider 302 can be designed as a self-locking slider with a locking function to further improve the stability of positioning; at the same time, the second fixed shelf 303 can use a modular design to adapt to more size changes.

[0036] In one possible implementation, an adjustable-distance locking structure 304 is provided on both sides of the second fixed shelf 303 near the slider position. The adjustable-distance locking structure 304 is used to lock the relative position of the slider 302 and the slide rail 301, thereby ensuring the stability of the second fixed shelf 303. During chassis handling, the locking structure ensures that the shelf position will not accidentally shift. This structure improves the stability and precise positioning capability of the shelf, further reducing vibration and impact during equipment operation. The adjustable-distance locking structure 304 can be pneumatically or hydraulically controlled, further improving the automation level and operational efficiency of locking.

[0037] In one possible implementation, a laser obstacle avoidance radar 4 is installed on the edge of the vehicle body 1. The laser obstacle avoidance radar 4 scans the surrounding environment in real time to detect obstacles and optimize the path during the AGV's operation, ensuring safe operation. The laser obstacle avoidance radar 4 significantly improves the intelligence and safety of the equipment, especially its adaptability in complex environments. The laser obstacle avoidance radar 4 can be replaced with ultrasonic radar or a visual sensor, selecting the appropriate detection solution based on different environmental requirements.

[0038] In one possible implementation, a safety emergency stop switch 5 and a tri-color warning light 6 are provided next to the second support mechanism 3 on the vehicle body 1. The safety emergency stop switch 5 is used to immediately cut off the power and operation of the AGV in an emergency, ensuring the safety of the equipment and personnel. The tri-color warning light 6 provides real-time feedback on the operating status, displaying the normal operation, warning, or fault status of the equipment through different colored lights. By configuring the safety emergency stop switch and the tri-color warning light, the operational safety of the equipment and the visual management of its operating status are significantly improved, facilitating timely response to emergencies.

[0039] The emergency stop switch 5 can be replaced with a wireless remote control emergency stop device to improve remote control capabilities. The three-color warning light 6 can be combined with an audible alarm function to enhance the warning effect.

[0040] In one possible implementation, two load-bearing wheels 7 are respectively provided on both sides of the bottom of the vehicle body 1, and a shock-absorbing servo motor 8 is provided next to each pair of load-bearing wheels 7. The load-bearing wheels 7 provide the mobility of the equipment, and their design ensures the load-bearing capacity and driving stability of the equipment. The shock-absorbing servo motor 8, through spring damping and rotation adjustment functions, ensures continuous contact of the load-bearing wheels 7 on uneven ground, reducing the impact of vibration on the equipment and chassis. This implementation improves the driving stability of the AGV on complex terrain, while protecting the equipment and chassis structure and extending its service life.

[0041] The load-bearing wheel 7 can be replaced with an omnidirectional wheel or a tracked wheel set to adapt to different ground conditions. The shock-absorbing servo 8 is designed to add electronic control functions, automatically adjusting the shock absorption intensity to optimize driving performance.

[0042] In one possible implementation, an RFID sensor 9 is located at the center of the bottom of the vehicle body 1. A magnetic navigation sensor 10 is mounted on one side of the RFID sensor 9, and an automatic charging brush block 11 is mounted on the other side. The RFID sensor 9 achieves precise device positioning by reading RFID tags on the ground or landmarks. The magnetic navigation sensor 10 provides a navigation path by detecting magnetic strips or signals on the ground. The automatic charging brush block 11 is used to contact the charging device to achieve automatic charging of the device. Through the combination of the RFID sensor 9 and the magnetic navigation sensor 10, the device can achieve high-precision autonomous positioning and path navigation. The automatic charging brush block 11 ensures the continuous operation of the device and reduces human intervention.

[0043] The RFID sensor 9 can be replaced with a visual positioning system, and the magnetic navigation sensor 10 can be combined with laser navigation technology to improve navigation flexibility. The automatic charging brush block 11 can be replaced with a wireless charging device to further enhance charging convenience.

[0044] In one possible implementation, the shock-absorbing servo 8 includes a spring-loaded shock-absorbing structure and a dual-axis rotary servo for maintaining continuous contact between the load-bearing wheel 7 and the ground. The spring-loaded shock-absorbing structure reduces vibration and impact during equipment operation by absorbing ground vibrations. The dual-axis rotary servo ensures the stability of the load-bearing wheel 7 during movement and its continuous contact with the ground by flexibly adjusting its direction and angle. The combined design of the spring-loaded shock-absorbing structure and the dual-axis rotary servo improves the equipment's adaptability to uneven ground, enhances stability during handling, and improves operational precision.

[0045] The shock-absorbing servo motor 8 can be replaced with a hydraulic or pneumatic shock absorber to adapt to different load and environmental conditions. Meanwhile, the control method of the dual-axis rotary servo motor can be upgraded to an intelligent algorithm, improving its dynamic adjustment capabilities.

[0046] Working Process: The AGV receives the handling task instruction through its control system. The laser obstacle avoidance radar 4 and magnetic navigation sensor 10 start working, planning the optimal travel path according to the pre-set task path and environmental layout to ensure safe and efficient operation. Under the guidance of path navigation, the AGV travels along the planned path to the chassis lifting area. When it reaches the designated position, the RFID sensor 9 reads the area identification information for precise positioning, and the three-color warning light 6 indicates the equipment status through corresponding color signals. The chassis is placed on the AGV's first support mechanism 2 and second support mechanism 3 by the lifting equipment. Through the cooperation of the slide rail 301 and slider 302 in the second support mechanism 3, the position of the second fixed rack 303 is adjusted to adapt to chassis of different sizes. After confirming that the chassis is stably placed, the adjustable locking structure 304 automatically locks to ensure safety. After the AGV completes the chassis loading, it moves to the chassis lifting area via the load-bearing wheels 7. During the journey, the spring damping structure of the shock-absorbing servo motor 8 reduces vibration, and the dual-axis rotating servo motor ensures that the load-bearing wheels 7 are in continuous contact with the ground, thereby ensuring the stability of chassis handling and the safety of the equipment. Upon reaching the chassis unloading point, the AGV stops at the designated position and confirms its accurate positioning via laser obstacle avoidance radar 4 and RFID sensor 9. Manually operated lifting equipment lifts the chassis off the AGV, and the AGV's no-load status is confirmed. At this time, the tri-color warning light 6 changes to an indication state, showing the equipment is ready for no-load operation. After completing the task, the AGV returns to the charging area according to the navigation path. Upon reaching the charging position, the automatic charging brush 11 contacts the charging device, initiating the charging process. Simultaneously, the AGV enters standby mode, receiving the next task instruction via magnetic navigation sensor 10 or other signals. After receiving a new handling task, the AGV repeats the above operations, achieving efficient and automated handling of heavy truck chassis.
