Project Background:

The body of the empty track freight train is mainly composed of bogies and lifting equipment, and the basic track is mainly composed of box girders and suspended support arms. It can generally be used for standard container transfer from shipping ports to railway yards. The customer requires a fully automatic docking device that can hook up and down containers on ground racks and suspended on overhead rail hoists, and can automatically adapt to the parking error (± 3m) of overhead rail trains and outdoor working environments.

Solution:

Hangfa provides an OmniTurtle heavy-duty AGV equipped with Mecanum wheels, with a carrying capacity of 40 tons and a total weight of 80 tons. By using a double scissor lifting device, it is possible to achieve a large stroke lifting of over 2 meters for standard containers of 20 feet, 40 feet, and 45 feet. The adjustable accuracy is better than ± 1mm, and the whole vehicle adopts a 24 wheel design, with each wheel set having independent hydraulic suspension. AGV adopts laser reflector navigation positioning to achieve workpiece picking and placing on the ground rack. The AGV system is equipped with a laser scanning position detection device that adopts a God's perspective. By identifying and analyzing sensor point cloud data, it can accurately determine the position of the empty track train and its lifting equipment, as well as the position of the container, guiding the AGV to achieve precise docking.
