Inspection system

An inspection system comprising a base, a boom lifting mechanism provided on said base and a detector mounting boom, wherein said boom lifting mechanism comprising at least two support arms arranged sequentially, said at least two support arms comprising a base arm and a distal arm, said base arm being connected to said base, said boom being mounted on said distal arm, said inspection system having a scanning state and a transporting state, two adjacent support arms of the at least two support arms being rotatably connected so that the height of said boom in the scanning state is different from that in the transporting state;

• wherein said boom comprising a first detection arm and a second detection arm rotatably provided on said first detection arm;
• wherein when said inspection system is in the scanning state, said first detection arm is horizontally arranged and said second detection arm is vertically arranged, and said boom lifting mechanism, said first detection arm and said second detection arm jointly constituting a door-shaped structure;
• and
• wherein when said inspection system is in the transporting state, said second detection arm is in the same direction as said first detection arm by rotation relative to said first detection arm, and said first detection arm and said second detection arm are both horizontally arranged.
