and the deflection detection assembly 7 is arranged on the travelling crane 2 and is used for detecting the deflection of the travelling crane 2 in the axial direction of the second saddle 4.
According to the invention, the position (along the direction of the first track 111) of the steel coil workpiece 01 on the second saddle 4 can be detected through the arranged offset detection assembly 7, so that the accidents such as rollover and the like of the steel coil workpiece 01 on the second saddle 4 are avoided; in addition, the invention can detect the overflow edge of the steel coil workpiece 01 by arranging the image detection sensor 5 at one end of the steel coil workpiece 01 arranged on the second saddle 4, thereby improving the delivery quality of the steel coil workpiece 01.
As shown in fig. 1, since the steel coil workpiece 01 needs to be put down to the second saddle 4 from the crane 2 on the second rail 112, during the putting down process, since the second saddle 4 is provided with two second seats 41, there may be a situation that the steel coil workpiece 01 protrudes too much on one side, causing the steel coil workpiece 01 to roll over to the place; therefore, to avoid the above situation, the offset detection assembly 7 is now provided, specifically, the offset detection assembly 7 includes two groups of detection probes, the two groups of detection probes are respectively disposed on two sides of the travelling crane 2 along the direction of the first track 111, and the two groups of detection probes are respectively disposed on two sides of the steel coil workpiece 01 along the axial direction.
Since the deflection of the steel coil workpiece 01 at the two second seats 41 has a permissible range, at least two detection probes are arranged for each group of detection probes; by measuring the length of the coil work pieces 01 in advance, a detection probe can be provided for each measured position of the coil work pieces 01 to be shifted, and a detection probe can be provided at a position which is beyond the allowable range.

step three, a crane in-place detector 8 detects the position of the crane 2; if the specified position is not reached, the crane 2 adjusts the position; specifically, the traveling crane 2 moves on the first track 111 until the traveling crane in-place detection 8 detects that the traveling crane 2 reaches a specified position, that is, the traveling crane 2 reaches the middle part of the first saddle 3 in the length direction; if the designated position is reached, executing the fourth step;
as shown in fig. 3, in the third step, when the travelling crane 2 moves to the first saddle 3, the offset detection assembly 7 detects whether the end face offset of the coiled steel workpiece 01 exceeds 25mm, and if so, the travelling crane 2 is stopped; if the offset detection assembly 7 does not find that the end face offset of the steel coil workpiece 01 exceeds 25mm, the movement of the steel coil workpiece 01 onto the second saddle 4 is continued.
Step four, the travelling crane 2 drives the steel coil workpiece 01 to move on the second track 112 until the steel coil workpiece moves to the second saddle 4; specifically, the travelling crane 2 drives the steel coil workpiece 01 to move to a position close to the second saddle 4, and the lifting assembly lifts the travelling crane 2; when the travelling crane 2 moves to the middle part of the second saddle 4 along the direction of the second track 112, the lifting assembly descends the travelling crane 2, so that the steel coil workpiece 01 is placed on the second saddle 4;
step five, when the steel coil workpiece 01 is placed on the second saddle 4; the image detection sensor 5 starts to detect, and the image detection sensor 5 detects whether the overflow coil of the steel coil workpiece 01 is larger than or equal to 20mm; if yes, the crane 2 pauses, and the steel coil workpiece 01 is packaged after being repaired; if not, the steel coil workpiece 01 is directly packaged.
Specifically, the image detection sensor 5 photographs one end of the steel coil workpiece 01, so as to determine whether the end of the steel coil workpiece has overflow coil, if the steel coil has inward shrinkage or protrusion, and if the steel coil exceeds 20mm compared with the flush end, the steel coil workpiece 01 cannot be repaired manually in a short time, and the steel coil workpiece 01 is repaired to a repair site after stopping.
In summary, the steel coil workpiece 01 can be ensured to be positioned in the middle of the first saddle 3 along the first track 111 direction by the driving in-place detector 8, so that the steel coil workpiece 01 is prevented from overturning on the first saddle 3; so that the steel coil workpiece 01 can measure the weight, surface defects and the like of the steel coil workpiece on the first saddle 3; and then to the second saddle 3, running through the second track 112; in addition, the invention can detect whether one end of the steel coil workpiece 01 has overflow edges or not through the arranged image detection sensor 5, so that the steel coil workpiece 01 can be dragged to a repair place for repair under the condition that the steel coil workpiece cannot be repaired manually for a short time, and the yield of the steel coil workpiece 01 is improved; in addition, the deviation detecting component 7 provided by the invention can correct the position of the second saddle 4 of the steel coil workpiece 01, and can prevent the steel coil workpiece 01 from turning on one of the second seats 41 on the second saddle 4.
