Detailed Description

The invention is further described below with reference to the accompanying drawings and examples.

The automatic unlocking method for the F-TR lock in the embodiment shown in fig. 1 is realized by an operation table, a controller, a driver, a lifting appliance height encoder, a lifting appliance rotary lock scale, a monitoring camera and the like.

The lifting appliance absolute value encoder is used for measuring the lifting height value of the lifting appliance in real time, the measuring precision is within 1mm, and the measured lifting height of the lifting appliance is transmitted to the automatic unlocking controller in real time.

The lifting appliance angle sensor is used for measuring the rotating angle of the lifting appliance in real time, the measuring precision is 0.1 degree, and the measured rotating angle of the lifting appliance is transmitted to the automatic unlocking controller in real time.

The monitoring camera is arranged on the side of a container track gantry crane unloading train, and is aligned with an F-TR lock of the train and a container corner, and the effect after each step of operation can be observed and confirmed through videos in the F-TR unlocking process.

The automatic unlocking controller is used for determining whether the container is completely separated from the F-TR or not by comparing the container weight and the unbalance loading data obtained from the production management system, and when the weight is not matched, the automatic unlocking controller prohibits the lifting of the lifting appliance, so that further accidents caused by container padlocks are avoided.

The first height in this embodiment is the height H1 of the box spreader, which is the basis of the subsequent lifting height, the second height H2 is the first lifting in-place height for the value H1+70mm, and the third height H3 is the second lifting in-place height for the value H1+120 mm. The first spreader angle is the box spreader angle R1 and the second spreader angle is R2 for values of R1+ 2.5.

In this embodiment, the automatic controller automatically controls lifting and rotation of the lifting appliance according to lifting handle information of the operating platform, lifting appliance height information and lifting appliance angle information, so that the container is safely disengaged from the train F-TR lock, and meanwhile, due to the fact that padlock redundancy safety protection is realized by spin-lock weight information, special working conditions such as further accidents caused by the fact that a container lock hole or the train F-TR lock is deformed and blocked can be avoided, and the method specifically comprises the following steps:

step 1, a rail gantry crane controller receives a train box unloading command, a driver normally operates a lifting appliance to place the lifting appliance above an operation box, the lifting appliance is locked, operation information and measurement information are transmitted to an automatic unlocking controller in real time, and a first height H1 and a first rotation angle R1 are recorded;

step 2, a driver operates a lifting handle to ascend and keep, an automatic unlocking controller receives a handle ascending signal, the automatic unlocking controller controls a lifting driver to operate the lifting appliance at a low speed to ascend, meanwhile, the lifting height of the lifting appliance is measured in real time through a lifting encoder, when the lifting height of the lifting appliance reaches a second height, the lifting of the lifting appliance is automatically stopped, the transverse and longitudinal stress on the container by an F-TR lock is relieved, the container is in a suspended state, and the weight W1 of each lock head of the lifting appliance is recorded;

step 3, after the lifting sling reaches a second lifting height, continuously keeping the lifting handle to lift, controlling a sling rotating driver to rotate the sling anticlockwise at a low speed by an automatic unlocking controller, and stopping a sling rotating mechanism when the sling reaches a second angle R2 to remove the container from being blocked by an F-TR eagle head lock, wherein the effect is shown in figure 3;

step 4, the lifting appliance reaches a second lifting height and a second rotation angle, the lifting handle is kept to lift, the automatic unlocking controller controls the lifting appliance to lift at a low speed according to lifting height information of the lifting appliance and rotation angle information of the lifting appliance, when the lifting height of the lifting appliance reaches a third lifting height, the lifting handle returns to zero, and the weight W2 of each lock head of the lifting appliance is recorded;

and 5, judging that the lifting appliance reaches a third lifting height, judging that W2-W1 is larger than 500KG, if not, completely separating the container from the F-TR lock, and if so, locking the container with the F-TR lock, outputting an alarm, prohibiting the lifting appliance from lifting, and completing an automatic unlocking process, wherein the effect is shown in figure 4.

By the aid of the system and the method, unlocking efficiency and smoothness of the F-TR lock can be effectively improved, and hidden dangers that manual unlocking control precision is insufficient, accidents are easily expanded after padlock operation and the like are solved.

It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are intended to be included within the scope of the invention as defined in the appended claims.
