Description

Technical Field

[0001] This utility model relates to the technical field of IGV vehicle body structure, and in particular to a dual-pallet synchronous forklift device for IGV logistics robots. Background Technology

[0002] With the development of logistics automation, AGVs (Automated Guided Vehicles) are being used more and more widely in various warehousing and logistics operations. Especially in large-scale warehousing systems, AGVs can efficiently complete the handling of goods, improve operational efficiency, and reduce labor costs. However, traditional AGVs can usually only handle one pallet at a time when carrying pallets, resulting in low efficiency when handling multiple pallets and failing to fully realize the potential of automated equipment.

[0003] Currently, most dual-pallet forklift devices on the market suffer from poor synchronization and low forklift accuracy. Especially in confined spaces or complex environments, the accuracy and stability of forklift operations are difficult to guarantee, easily leading to pallet shifting or jamming. Traditional dual-pallet handling methods often require multiple adjustments, resulting in wasted operation time and failing to meet the demands for efficient and precise automation. Therefore, how to improve the working efficiency and operational accuracy of equipment while ensuring synchronized and accurate pallet forklift operations has become a crucial issue in logistics robot technology.

[0004] Furthermore, forklifts are prone to significant impact and wear during frequent operation, especially in environments with repeated operations, which can lead to increased equipment failure rates and higher maintenance costs. To ensure stable long-term operation, a design solution that effectively mitigates impact and reduces wear is needed. Therefore, existing technologies still face significant technical bottlenecks in improving handling efficiency and extending equipment lifespan.

[0005] In view of this, the inventors have specifically designed a dual-pallet synchronous forklift device for IGV logistics robots, which leads to this invention. Utility Model Content

[0018] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0019] This utility model relates to a dual-pallet synchronous forklift device for IGV logistics robots, mainly used to improve the forklift efficiency and accuracy of logistics robots in automated operations such as warehousing and sorting, and is especially suitable for scenarios that require the simultaneous handling of two pallets. Through optimization and innovation of the existing single-pallet forklift structure, this utility model solves the technical problems of asynchronous forklifting, inaccurate positioning, and easy damage in traditional structures, and has the advantages of simple structure, high synchronization, and strong adaptability.

[0020] like Figure 1 As shown, the device is installed on the IGV (Intelligent Guided Vehicle) logistics robot body and mainly includes a base plate structure 1, a double fork arm structure 2, a synchronous drive mechanism 3, a buffer and shock absorption structure 4, and an optional laser detection unit. All parts work together to simultaneously insert, pick up, and transport two standard pallets, ensuring stability and safety during operation.

[0021] The base plate structure 1 serves as the mounting foundation for this device, fixed to the IGV robot body, and supports and connects all functional components of the forking device. The base plate is preferably made of high-strength steel plate and has multiple pre-drilled mounting holes (6 positions) for quick installation of components such as the sliding rail 31 and drive motor 34, facilitating overall assembly and subsequent maintenance. Its rigidity and stability directly affect the alignment accuracy and mechanical response capability during the forking process.

[0022] like Figure 1 As shown, the double fork arm structure 2 is mounted on the base plate structure 1, including a first fork arm assembly 21 and a second fork arm assembly 22 that are symmetrically arranged on the left and right sides. The two forks are used to insert into and support two pallets respectively, achieving stable clamping through the engagement of the fork ends with slots on the bottom of the pallets. To accommodate the handling needs of pallets of different sizes, the two fork arm assemblies are designed with adjustable lengths, allowing the forks to extend and retract within a certain range via adjusting screws or sliders, thus enhancing the versatility of the device.

[0023] To ensure synchronized movement of the two fork arm assemblies during pallet insertion and removal, the device is equipped with a synchronous drive mechanism 3. This mechanism includes a sliding rail 31 fixedly mounted on the base plate structure 1, a slide block 32 moving along the rail, a connecting assembly 33 connecting the slide block 32, and a drive motor 34 driving the connecting assembly 33. Preferably, the sliding rail 31 adopts a U-shaped guide rail structure to improve guiding accuracy and load-bearing capacity; the slide block 32 is fixedly connected to the rear end of the fork arm to transmit power to it. The connecting assembly 33 can adopt a steel connecting rod or rack and pinion 331 structure, ensuring mechanical synchronization between the two slide blocks 32 while maintaining structural stability. The drive motor 34 is linked to the connecting assembly 33 through a lead screw mechanism 5 or a gear 332-rack and pinion 331 mechanism, enabling high-precision control of the synchronous movement of the two fork arms and effectively preventing pallet misalignment or jamming caused by step deviation.

[0024] In actual operation, the insertion or removal of the fork arm from the pallet inevitably generates a certain amount of impact force. To protect structural components and improve the smoothness of the fork lifting process, this invention provides a buffer and shock absorption structure 4 on the front end of the fork arm or on the base plate structure 1. This structure is preferably a rubber pad, spring, or flexible shock absorber, which can absorb part of the impact energy the moment the fork arm contacts the pallet, reduce structural fatigue, and extend the service life of the equipment.

[0025] like Figure 1 As shown, to further improve the automation control precision during the forklift process, the device can also be equipped with a laser sensor 7 to detect status information such as whether the pallet is aligned and whether the forks are inserted in place. This sensor is located at the front end or in front of the base plate of the double forklift structure 2, and can provide real-time feedback on the insertion status to the robot control system, assisting the robot in adjusting its position or implementing safety strategies to avoid device damage or cargo tipping due to misoperation.

[0026] The dual-pallet synchronous forklift device provided by this utility model not only has a reasonable structural design and good mechanical synchronization capability, but also has significant advantages in improving work efficiency, reducing operational errors, and enhancing equipment adaptability. Compared with the traditional single-pallet structure, this device can complete the forklift and handling operations of two pallets at one time, greatly improving the processing capacity per unit time, and is suitable for large-volume, high-frequency logistics operation environments.

[0027] In addition, the various modules of this device are designed with good modularity and scalability, making it easy to match with different models of IGV robots. Different sensors, buffer structures or drive mechanisms can be selected according to the needs of field applications, which has broad prospects for engineering applications.

[0028] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
