Description

Technical Field

[0001] The present invention relates to a support device, and more specifically to a support device for guiding a transport vehicle to carry heavy loads. Background Art

[0002] Guided transport vehicles generally require support devices. Existing support devices generally include flat support devices, lifting support devices, and tray support devices. Flat support transportation is a traditional transportation method, which has the advantages of simple structure, easy use, easy maintenance, and large load-bearing capacity. For a guided transport vehicle with a flat support device, because it is relatively convenient for loading and unloading large and heavy goods, and can load more goods than other guided transport vehicles of the same specifications. The flat support belongs to an open-source support method, and box corner fixing devices can be installed according to the distance between the box corners of the goods, and are installed on the flat plate with screws to ensure the reliable fixation of the goods and ensure transportation safety. However, the flat support device has disadvantages such as large size, poor passability in narrow warehouse spaces, and the need to install various box corner fixing devices to adapt to the transportation of different types of goods. The lifting support device can lift the goods rack and transport it to the designated position, and can rotate 360°, which is suitable for running in narrow spaces or flat warehouses. However, it is only suitable for the transportation of small goods and not suitable for the transportation of large heavy loads. The tray support device can achieve reliable locking with the storage rack and the goods; when the tray enters / leaves the warehouse, it cooperates with the guided transport vehicle and the storage rack to realize automatic transfer, automatic unlocking / locking. It is mostly used for the rapid access of goods in a three-dimensional storage warehouse. It has the advantages of reliable fixation, reliable load-bearing, binding of goods information, and intelligent storage.
