Abstract
The invention discloses an intelligent detection system for an ordinary gantry crane container F-TR lock. The intelligent detection system comprises four tension sensors connected to an ordinary container gantry crane, and a signal recognition processor connected with the tension sensors. The tension sensors are column strain sensors each of which comprises a load column beam. The middle of the load column beam is provided with two corresponding coaxial blind holes in radial symmetry about the load column beam. Resistance strain gauges are disposed in the blind holes. Pulleys for fixing a wire rope fixedly sleeve the load column beams. Support plates are fixed to both sides of the pulley and outside the load column beam. The tension values of the four tension sensors are changed when the ordinary container gantry crane lifts. When the deviation of the tension change value of one tension sensor and the tension change value of another one or a few tension sensor does not exceed a set threshold, it is detected that the container F-TR lock is not normally disengaged to achieve rapid alarm prompting.

F-TR lock connections, it is ensured that the fixation of container, when container needs unloading to depart from, by 1#F-TR locks, 2#F-TR locks, 3#F-TR
Lock and 4#F-TR locks depart from container location hole, the container location hole at four turnings of container top with of the invention four
Pulling force sensor (1# pulling force sensors, 2# pulling force sensors, 3# pulling force sensors and 4# pulling force sensors) connects, and works as container
When common door hangs lifting container, the pulling force that each pulling force sensor is subject to can keep a value of thrust (packaging being basically unchanged
Case overall weight and unbalance loading amount no longer increase substantially), now system can receive the metastable detection that every sensor is provided
Signal.
See Fig. 8, when normally lifting by crane, four pulling force sensor signal output differences will not be very big, i.e.,:Four four pulling force are passed
The value of thrust of sensor output is not above the departure of 2t；See Fig. 9, the four F-TR sensings when improper lifting, on suspender
Device signal output departure can be very big, i.e.,:Departure of the value of thrust of four sensors output more than 3t (4# pulling force sensors and
Other 3 pulling force sensor values of thrust differ by more than 3t).4# pulling force sensors are the container body pulling force of the 4th, container
Value plus without departing from the weight sum that is gradually pulled up of flatcar vehicle.Using this overproof value, can be with by analysis circuit
Container F-TR locks are judged immediately without normal disengaging, and alarm 05 realizes that warning function or control container common door hang 06
