が発生するという問題があった。2. Description of the Related Art In a coke oven in which coke is obtained by carbonizing coal, a coking chamber and a combustion chamber separated by refractory brick partitions are alternately arranged, and coal charged from a coal charging port above the coking chamber is removed. The coke is extruded from the side of the carbonization chamber after heating by the adjacent combustion chamber and completion of carbonization. However, the partition walls of the carbonization chamber are subject to temperature fluctuations from room temperature to 1200 ° C. due to the dry distillation cycle, and are subjected to friction and extrusion stress generated during coke extrusion. Damages such as breakage occur, and if left unchecked, the furnace body strength and furnace life will be reduced, or penetration of the partition walls will cause incomplete combustion, causing problems such as black smoke generation and fluctuations in the carbonization temperature. There was a problem.

確に把握できないという問題があった。For this reason, after the coke is extruded, damage is visually confirmed from a side opening of the carbonization chamber, but it is difficult to observe a deep portion due to a high temperature. Further, since the diameter of the combustion chamber was about 80 mm, visual observation from outside the furnace was impossible. Therefore, there have been proposed devices and methods for inserting a video camera into a coke oven to check a partition wall. (For example, JP-A-3-105195, JP-A-62-2
88503, JP-A-63-252242)
However, these devices and methods cannot accurately detect the width, unevenness, size, or displacement of a partition wall of a refractory brick due to joint breakage, rough skin, penetration, cracks, or damage, and the displacement of a partition wall cannot be accurately detected. There was a problem that it was not possible to accurately determine the repair time or the life of the furnace.

The imaging signal taken into the AM is subjected to difference processing, binarization processing,
Reduction / enlargement processing is performed to detect damaged joints, such as broken joints, rough skin, penetrations, cracks, and missing parts of refractory bricks. Since the reference linear light SL that scans the detected damaged portion is emitted from the light projecting unit 9 having the light projecting axis angle θ that intersects the imaging optical axis RA orthogonal to the partition wall W at the reference partition position SW, When the reference linear light SL is irradiated over the uneven portion of the damaged portion and the non-damaged portion of the partition (becoming the reference partition position), the reference linear light SL is changed according to the amount of unevenness of the damaged portion. S
The projection linear light RL is displaced below or above W, and a partial displacement amount h having a partial displacement width s is generated. The partial displacement width s and the partial displacement amount h are calculated from a captured image having a fixed ratio to the actual size, and the actual displacement amount, that is, the width of the damaged portion and the unevenness of the damaged portion are measured.

を行う。Further, when the partition wall W is displaced or when the damaged portion is larger than the reference linear light SL, the position of the projection linear light RL fluctuates from the position of the reference linear light SL. The position of the linear light RL is calculated from the captured image having a fixed ratio with the actual size, and the difference between the position of the projected linear light RL and the position of the reference linear light SL stored in the memory is calculated. Calculate the amount of displacement. In this way, the damaged part can be accurately measured to find serious damage such as joint breaks, penetrations, cracks, defects, etc., to prevent the generation of black smoke resulting from incomplete combustion, and to reduce fluctuations in the carbonization temperature. That is exactly what happens. Then, while moving the mobile trolley 1, a large number of the carbonization chambers 2 and the partition walls W of the combustion chambers 3 are sequentially inspected, and the captured image or the image-processed image data is transferred to the position data of the mobile trolley 1 by the position detecting device 18, that is, the image is captured. The information that specifies the carbonization chamber 2 and the combustion chamber 3 that have performed the above is matched with the captured image. Then, a comparison is made between the captured image of the carbonization chamber 2 or the combustion chamber 3 that was inspected at the next inspection and the previous captured image,
The displacement of the damaged part is examined, and the repair time of the furnace and the life of the furnace are predicted.

に寄与するところ極めて大なものである。According to the present invention, as is apparent from the above description, the projection linear light projected on the partition wall is formed by intersecting the reference linear light with the imaging optical axis orthogonal to the partition wall at a predetermined light projection axis angle. Length and position according to the amount of displacement of the partition,
Since the projected linear light is displaced into a partial displacement amount and a partial displacement width corresponding to the unevenness amount and the width of the damaged portion of the partition wall, the displacement amount of the partition and the length, width, unevenness amount, etc. of the damaged portion can be accurately measured. Thus, it is possible to accurately predict the degree of damage to the furnace, the repair time, and the life of the furnace.

隔壁の損傷部測定方法。A reference linear light SL having a constant projection axis angle θ at which an intersection of the imaging section (8) with an imaging optical axis RA becomes a reference partition position SW is projected from the projection section (9). , The reference linear light SL
The imaging unit in which the partition wall W on which the image is projected is separated from the reference partition position SW by a fixed distance L 0 by making the imaging optical axis RA orthogonal to the partition wall W.
(8), the captured image is subjected to image processing to detect a damaged portion of the partition wall W, and the amount of displacement between the captured projected linear light RL and the reference linear light SL and the projected linear light RL From the partial displacement amount h and the partial displacement width s, the displacement of the partition wall W and the width of the damaged portion,
A method for measuring a damaged portion of a coke oven partition, comprising measuring an amount of unevenness of the damaged portion.
