Problems solved by technology

[0003] At present, during the hoisting process, the crane driver can only see the near side ladle trunnion and the crane hook due to the blocking of the line of sight, but cannot see the near side far ladle trunnion and the crane hook, and can only rely on experience or feeling Judging whether the far side trunnion is correctly aligned with the crane hook, if the driver is inexperienced, fatigued, distracted, etc., it is easy to make a misjudgment, resulting in major accidents such as the ladle overturning and falling off

Embodiment 1

[0062] as attached figure 1 - attached image 3 As shown, a ladle trunnion hoisting alignment identification device, which includes a main control unit, and a first hoisting alignment image acquisition unit, a second hoisting alignment image acquisition unit and a lifting alignment unit respectively connected to the main control unit Lift control loop;

[0063] The ladle trunnion and the hook tip of the crane are painted with white marks;

[0064] The first hoisting alignment image acquisition unit captures in real time the image of the trunnion on one side of the ladle and the white mark of the crane hook tip as the first alignment image information, and transmits it to the main control unit;

[0065] The second hoisting alignment image acquisition unit captures in real time the image of the trunnion on the other side of the ladle and the white mark of the crane hook tip as the second alignment image information, and transmits it to the main control unit;

[0066] The lift...

Embodiment 2

[0073] as attached Figure 4 And attached Figure 5 As shown, a ladle trunnion hoisting alignment identification method, using the alignment identification device described in the above claims, includes the following steps:

[0074] Step 1, paint the end faces of the trunnions on both sides of the ladle to be hoisted and the tip of the crane hook in white;

[0075] Step 2, moving the ladle to be hoisted to a hoisting position, and moving the hook below the trunnion;

[0076] Step 3, the first hoisting alignment image acquisition unit and the second hoisting alignment image acquisition unit collect the alignment image information of the trunnions on both sides of the ladle and the crane hook in real time, and transmit it to the main control unit;

[0077] Step 4, the main control unit recognizes two types of outline rectangles according to the alignment image information, and determines whether it is a trunnion outline rectangle or a hook outline rectangle according to the a...

Embodiment 3

[0097] The difference between this embodiment and embodiment 2 is: as attached Image 6 As shown, in the step 4, the main control unit recognizes the first white area representing the outline rectangle of the steel ladle trunnion according to the alignment image information, and the specific steps are:

[0098] Step 4.1, set the leftmost pixel position of the first white area as Left1=0, the uppermost pixel position Top1=0, the rightmost pixel position Right1=0, the lowermost pixel position Bottom1=0; white pixels Number N(i)=0;

[0099] Step 4.2, progressively scan the alignment image information; set i=0;

[0100] Step 4.3, set j=0;

[0101] Step 4.4, set k=0;

[0102] Step 4.5, if the (i, j+k)th pixel is white, then the number of white pixels in row i is N(i)=N(i)+1;

[0103] Record the first white pixel position F(i)=j of the i-th line, and the last white pixel position L(i)=j+N(i) of the i-th line, and then go to step 4.6; otherwise Go directly to step 4.8;

Abstract

The invention provides a steel ladle trunnion hoisting aligning recognition device and method. The recognition device comprises a first hoisting alignment image collecting unit, a second hoisting alignment image collecting unit and a lifting control loop, wherein a trunnion on one side of a steel ladle and a white identification of a lifting hook tip of a crane are shot by the first hoisting alignment image collecting unit in real time and taken as first alignment image information, and the first alignment image information is transmitted to a main control unit; a trunnion on the other side ofthe steel ladle and the white identification of the lifting hook tip of the crane are shot by the second hoisting alignment image collecting unit and taken as second alignment image information, andthe second alignment image information is transmitted to the main control unit; a lifting control loop is connected with the main control unit, which is used for controlling the lifting and lowering of the lifting hook of the crane; the main control unit drives the lifting control loop to work according to the information returned by the first hoisting alignment image collecting unit and the second hoisting alignment image collecting unit. The steel ladle trunnion hoisting aligning recognition device and method are scientific in design, high in practicability, simple in structure and accuratein identification.

Description

technical field [0001] The invention relates to the technical field of steel ladle hoisting, in particular to a ladle trunnion hoisting alignment identification device and method. Background technique [0002] During the steelmaking process of iron and steel enterprises, the ladle often needs to be lifted by a crane and transferred to different production process positions. [0003] At present, during the hoisting process, the crane driver can only see the near side ladle trunnion and the crane hook due to the blocking of the line of sight, but cannot see the near side far ladle trunnion and the crane hook, and can only rely on experience or feeling Judging whether the far side trunnion is correctly aligned with the crane hook, if the driver is inexperienced, fatigued, distracted, etc., it is easy to make a misjudgment, resulting in major accidents such as the ladle overturning and falling off. [0004] In order to solve the above existing problems, people have been seeking...
