Description

Method for detecting whether F-TR lock falling position is normal or not

Technical Field

The invention relates to a method for detecting whether an F-TR lock drop position is normal or not.

Background

In the existing railway container cargo transportation, a special container flat car is mostly adopted, an F-TR lock is used as an important part for guaranteeing the transportation safety, and the transportation safety is greatly influenced by the normal falling position of the F-TR lock. The detection of the F-TR lock is divided into detection before loading, detection during loading and detection after loading in actual operation. At present, the detection of the three stages mostly depends on manual detection, the efficiency is low, the detection is easy to miss, and the detection is complex.

Disclosure of Invention

The invention aims to overcome the defects of the existing product and provide a method for detecting whether an F-TR lock drop position is normal or not.

In order to achieve the purpose, the invention is realized by the following technical scheme:

a detection method for whether an F-TR lock drop position is normal or not comprises the following steps:

step one, judging whether a rope loosening signal of a lifting appliance on the container crane is acquired, if the rope loosening signal of the lifting appliance on the container crane is acquired, starting releasing the container by the lifting appliance on the container crane and entering step two, and if not, exiting;

acquiring heights of four corners of the top surface of the container from the plane of the flat car through sensors, wherein the heights of the four corners from the plane of the flat car are represented as H1, H2, H3 and H4, so that when the spreader starts to release the container, distances of four corners of the bottom surface of the container from the plane of the flat car are obtained, the distances of the four corners of the bottom surface of the container from the plane of the flat car are represented as H1, H2, H3 and H4, the height of the container is known as H, H1= H1-H, H2= H2-H, H3= H3-H and H4= H4-H;

and step three, judging whether H1, H2, H3 and H4 are all smaller than the height of the FTR lock, if H1, H2, H3 and H4 are all smaller than the height of the FTR lock, the container is normally located on the flat car, namely the FTR lock is normally located, otherwise, the container is not normally located on the flat car, namely the FTR lock is not normally located.

Preferably, the top and bottom surfaces of the container are rectangular.

Preferably, the container is located above the flatbed, and the spreader is located above the container.

Preferably, in the second step, the sensor is a laser radar sensor.

The invention has the following beneficial effects: the invention detects whether the falling position of the F-TR lock is normal or not by detecting the loading stage, is very convenient to use, has simple detection method, low cost, very high efficiency and high speed of detection, and can not cause the problem of missed detection.

FIG. 1 is a schematic view of the present invention in operation.

Detailed Description

The technical scheme of the invention is further explained by combining the attached drawings of the specification:

step one, as shown in fig. 1, judging whether a rope loosening signal of a spreader 3 on the container crane is acquired, if the rope loosening signal of the spreader 3 on the container crane is acquired, the spreader 3 on the container crane starts to release the container 2, namely the container crane is in a loading stage, and entering step two, otherwise, exiting;

step two, as shown in fig. 1, acquiring heights of four corners of the top surface of the container 2 from the plane of the flat car 1 through sensors, wherein the heights of the four corners from the plane of the flat car 1 are represented as H1, H2, H3 and H4, so that when the spreader 3 starts to release the container 2, the distances of the four corners of the bottom surface of the container 2 from the plane of the flat car 1 are obtained, the distances of the four corners of the bottom surface of the container 2 from the plane of the flat car 1 are represented as H1, H2, H3 and H4, the height of the container 2 is known as H, the H1= H1-H, the H2= H2-H, the H3= H3-H, and the H4= H4-H;

and step three, judging whether H1, H2, H3 and H4 are all smaller than the height of the FTR lock, if H1, H2, H3 and H4 are all smaller than the height of the FTR lock, enabling the container 2 to normally fall on the flat car 1, namely the FTR lock normally falls, otherwise enabling the container 2 to be abnormal in falling on the flat car 1, namely the FTR lock abnormally falls. The top and bottom surfaces of the container 2 are rectangular. The container 2 is positioned above the flat car 1, and the spreader 3 is positioned above the container 2. In the second step, the sensor is a laser radar sensor.

The method is characterized in that the hanger is in a parallel state relative to the container at the moment when the hanger loosens the rope, the height of the four corners of the bottom surface of the container from the flat car 1 can be deduced by measuring the height of the four corners of the top surface of the container 2 from the flat car 1, if H1, H2, H3 and H4 are all smaller than the height of the FTR lock, the container 2 normally falls on the flat car 1, namely the FTR lock normally falls, otherwise, the container 2 abnormally falls on the flat car 1, namely the FTR lock abnormally falls, and the container restarts to fall.

The invention detects whether the falling position of the F-TR lock is normal or not by detecting the loading stage, is very convenient to use, has simple detection method, low cost, very high efficiency and high speed of detection, and can not cause the problem of missed detection.

It should be noted that the above list is only one specific embodiment of the present invention. It is clear that the invention is not limited to the embodiments described above, but that many variations are possible, all of which can be derived or suggested directly from the disclosure of the invention by a person skilled in the art, and are considered to be within the scope of the invention.
