Description

Technical Field

[0001] This utility model relates to the field of modular equipment technology, specifically a modular quick-installation structure for a security door of an air cargo terminal assembly platform. Background Technology

[0002] In the scenario of pallet assembly at air cargo terminals, safety doors are the core facilities to ensure the safe connection between TV trucks and the assembly platform. Traditional safety doors are mostly integral welded structures, which have problems such as long installation cycles, poor adaptability, and high maintenance costs.

[0003] This modular quick-install structure consists of four parts: a door frame module, a sensor protection module, an intelligent control module, and quick-install connectors. The number of door frame modules is selected according to the size of the assembly platform, and the complete door frame is assembled by using quick-install connectors. After installing the sensor protection and intelligent control modules and connecting to the freight station management system, the infrared sensors detect the status of the TV vehicle and personnel in real time, and trigger alarms and lockouts when abnormalities occur.

[0004] However, the above-mentioned equipment has obvious shortcomings in use. Existing assembly platform safety doors mostly use welding and bolt fastening methods for fixing. During installation, dozens of bolts need to be welded or tightened point by point. During disassembly, the weld seams need to be cut or the bolts need to be removed one by one, which seriously affects the turnover efficiency of the cargo terminal. In view of this, we propose a modular quick-installation structure for the assembly platform safety door of the air cargo terminal. Utility Model Content
