Efficient, accurate and safe transfer of heavy material workpieces is achieved.

Description

technical field [0001] The present invention relates to the logistics operation system of the workshop of the heavy equipment manufacturing industry, more specifically, relates to a kind of heavy-duty right-angle track changing RGV trolley device and its track changing operation. Background technique [0002] In the manufacturing process of the automated manufacturing system, the workpiece transportation equipment and storage equipment are inseparable to complete the flow and storage of various materials. The widely used automatic conveying equipment includes conveyor belts and transport trolleys. [0003] Rail Guide Vehicle (RGV for short) is a means of transportation that walks along the rails in a straight line. The gear rack on the side is meshed and driven by AC and DC servo motors; the trolley driven by it is pulled by an external chain cable, and a guide pin is installed on the front and rear of the chassis of the trolley, and a set of grooves with fixed routes are re...

AI Technical Summary

Problems solved by technology

The characteristics of the trolley are: 1. The acceleration and moving speed are relatively fast, which is suitable for transporting heavy workpieces; 2. Because the guide rail is fixed, the running is stable and the parking position is relatively accurate; 3. The control system is simple, reliable, low manufacturing cost, It is easy to promote and apply; 4. It is inconvenient to change the walking route, and the turning angle cannot be too small; 5. The noise is loud, which affects the operator's monitoring of the processing status and protection of his own safety

[0004] At present, in the process of upgrading the automation and intelligentization of the heavy-duty manufacturing industry, the automated logistics operation system of the production line in the workshop is mostly based on the later construction of the existing factory building, which makes the basic construction difficult for the traditional RGV transfer track system of the mother and child vehicles. The construction period is long, the excavation volume is large, and the infrastructure construction cost of the space-constrained logistics transfer system is high, and the construction period is long and other defects; and most of the transfer methods in the existing industry use the main line straight rail RGV bicycle to travel, and the branch line docking position adopts a cross conveyor line Or the structural form of the docking of the branch line trolley, which adds a transfer, the overall logistics operation rhythm and docking accuracy are not high, and the efficient operation of the entire logistics line cannot be effectively guaranteed
