Description

Technical Field

[0001] The utility model relates to the technical field of warehousing equipment, in particular to a jacking structure for an AMR transport robot. Background Art

[0002] Logistics warehousing is an essential component of modern supply chain management, integrating efficient cargo storage, sorting, packaging, and distribution. Advanced warehouse management systems and automated equipment enable precise inventory control and rapid response, ensuring the smooth flow of goods throughout the supply chain. Logistics warehousing not only optimizes storage space utilization and reduces operating costs, but also enhances customer service through real-time tracking and data analysis. From the receipt of raw materials to the shipment of finished products, every step is meticulously planned and managed to meet market demand for fast, accurate, and safe delivery of goods. AMRs are used in logistics warehousing to autonomously move and transport pallets. The system generates signals to control the AMRs' automatic operation. Using their own electrical system, the AMRs connect to the WMS system via a wireless network. Upon receiving system instructions, they move to designated locations and transport pallets to designated storage points, enabling the storage and retrieval of goods.

[0003] AMR trucks use lidar navigation, which requires more complex algorithms to constantly adjust their routes. The position of the AMR vehicle body must be precisely controlled when entering and exiting storage and retrieval addresses. Other electrical systems are needed to assist in precise positioning to achieve the task of safely storing and retrieving pallets. This places high demands on the extraction of signals around the site and the algorithm system of the onboard computer. When arriving at the designated pickup or delivery point, the trolley's lifting mechanism moves to raise or lower the cargo pallet based on instructions, lifting it away from the original delivery point or dropping it to the designated location. AMR trucks in the prior art have longer support plates due to the lengthening of the vehicle body, which changes the lifting fulcrum. This can easily lead to insufficient lifting fulcrums, and large-sized cargo pallets tend to shake after being lifted, affecting the lifting stability.

[0004] Therefore, it is necessary to provide a lifting structure for an AMR handling robot to solve the above technical problems. Utility Model Content

[0008] As a further scheme of the utility model, a chain wheel is fixed on the output end of the direct current servo motor and the side surface of the transmission shaft, and a chain is connected between the two chain wheels.

[0009] As a further scheme of the utility model, a reversing device is arranged in the vehicle body between the two screw lifting mechanisms, a bevel gear b that is meshingly connected with the bevel gear a in the screw lifting mechanism is fixed on one end of the transmission shaft, and a shaft coupling is connected between the other end of the transmission shaft and the reversing device.

[0010] As a further scheme of the utility model, a mounting bracket is fixed on the inner side wall of the vehicle body, and the direct current servo motor is fixed on the mounting bracket.

[0011] As a further scheme of the utility model, a material supporting plate is fixed on the top end of the material top body.
