Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

The utility model provides a harbour portal crane prevent wind mooring cable interlocking device, includes four sets of prevent wind mooring cable detection device 1, prevent wind mooring cable detection device 1 and include the protective housing 5 of cylindricality, and 5 upper ends of protective housing are equipped with can dismantle lid 51, the lower extreme of connection and are equipped with swing joint's suspension hook 4, the inside lower extreme of protective housing 5 is equipped with can dismantle the inductive pick-up 2 of connection, is equipped with the control box 6 of electricity connection on the inductive pick-up 2, and control box 6 is located protective housing 5's the outside.

An air switch 61 and an overhaul socket 62 which are electrically connected with a 220V alternating current power supply in parallel are arranged in the control box 6, and a direct current power supply 63 and a logic controller 64 which are electrically connected with each other in series are arranged on the air switch 61.
