Abstract
The present invention discloses a pulling device for a container inspection system including a pulling vehicle () arranged inside an inspection passage, a winch () and wire tension mechanisms ('). Front and rear ends of the pulling vehicle are connected to a wire rope so as to drive the pulling vehicle to move back and forth inside the inspection passage. The wire rope connected to front and rear ends of the pulling vehicle is wound around a wire tension mechanism arranged at front and rear ends of the inspection passage and is turned around by a swerving pulley () which is positioned at the same horizontal plane as that of the wire rope, the pulling vehicle, and the wire tension mechanisms, then the wire rope passes through the vertical pulley block, and finally it is connected to a single winding drum () of the winch () and wound around the single winding drum () respectively. Compared with the prior arts, the present invention is advantageous in reduction in equipment investment and decrease in area occupied by the pulling device. Further, the inspection operation can be carried out more reliably and safely.
