Problems solved by technology

[0004] The gantry manipulator has the advantages and foundation of large load, fast speed, high precision, large-span movement, and programmable automatic control. It meets the requirements of high speed, large load, and large span for handling and palletizing. The slider-driven gantry manipulator has high precision requirements, limited carrying capacity, and high cost. It is not suitable for large-span and heavy-load movements. It needs a reasonable structural design to achieve this goal.
But the key issue in the design is to solve the guide drive of the gantry manipulator truss, as well as the stability and safety issues during rapid start-stop and high-speed movement

Description

technical field [0001] The invention relates to the field of cargo handling manipulators used in long-distance logistics in workshops, and in particular to a truss guiding drive device for high-speed, heavy-load and large-span gantry manipulators. Background technique [0002] At present, in workshop logistics operations, logistics equipment such as forklifts or cranes are often used for transporting heavy goods that need to be palletized over long distances. Completed by human operation. In order to improve logistics efficiency, in a relatively small workshop, increasing the transportation capacity by adding logistics equipment will inevitably lead to increased difficulty in logistics on-site management, and even chaos in logistics order. The existing methods of long-distance transport and palletizing of heavy goods have problems such as low work efficiency, poor quality of palletizing, large amount of labor, and high labor intensity, which has become a bottleneck affectin...
