Is installed. 8c in the figure is a motor for rotating the annular member 8a.

A single cable C is connected to the control device 18. The cable C is connected to a control room H disposed on the ground outside the chimney 2 via a cable reel R disposed outside the chimney 2. The cable C is fed out from the cable reel R as the cleaning and inspection device 1 is moved up and down. Or rolled up. Reference numeral 36 in the figure denotes a power supply unit for supplying power to the operation device 35.

Further, inside the control box 20, there is provided a position detector for detecting the height position of the cleaning and inspection device 1 based on the amount of unwinding and winding of the rope body 7B of the winch device W, and the first arm 11 And a circumferential detector for specifying a circumferential position from the rotation angle of the second arm 23 and the absolute azimuth of the gyrocompass.

In the cleaning and checking device 1 configured as described above, the operator operates the operating device 35 in the operating room H,
Further, the winch device W is driven. This makes the cable 7B
Is wound up, the cleaning and inspection device 1 rises, and the cleaning and inspection device 1 rises to the upper end of the chimney 2. Next, the third cylinder device 30 is driven, and the fixing roller 31 attached to the distal end of the third arm 29 abuts against the inner surface of the chimney 2 to position and fix the entire device with respect to the chimney 2.

Next, the control device 18 drives the first cylinder device 12, whereby the peripheral surface of the cleaning brush 13 contacts the lining surface 2a of the chimney 2, and the control device 18
When the cleaning motor 14 and the rotating motor 9 are driven, the rotating body 10 slowly rotates around the vertical axis, and the cleaning brush 13 rotates around the vertical axis 13a, and the chimney 2
Is cleaned.

When the cleaning brush 13 makes a full turn around the lining surface 2a of the upper end of the chimney 2, the third cylinder device 3
0 to drive the fixing roller 31 to the chimney 2
To make the entire device lowerable.

Next, the winch device W is driven so that the cleaning brush 13 is lowered by an amount slightly smaller than the height of the cleaning brush 13 (for example, 40 cm), and the rope body 7B is extended, and the cleaning brush 13 is rotated and turned. The lining motor 2 is rotated in the reverse direction to clean the lining surface 2a.

By performing such an operation from the upper end to the lower end of the chimney 2, the lining surface 2a of the chimney 2
Clean everything. During the cleaning as described above, the second cylinder device 24 is contracted so that the tapping sound inspection device 26 does not contact the lining surface 2a.

Next, when the cleaning operation is completed, the first cylinder device 12 is contracted and the cleaning brush 13 is moved to the lining surface 2a.
, The entire area from the lower end to the upper end of the lining surface 2a is photographed at a fixed pitch by the primary inspection photographing device 22 and the unevenness sensor (not shown), and the turning center of the turning body 10 (vertical axis) The distance from 10a) to the lining surface 2a is measured.

The image data is analyzed by an analyzer in the operation room H. If the lining surface 2a is damaged, the winch device W is driven to move the second arm to the height at which the lining surface 2a is damaged. 23, the third cylinder device 30 is driven, and the fixing roller 31 is used to position the device. Then, the second cylinder device 24 is driven to move the hammering sound inspection device 26 to the place where the damage has occurred, and the hammering sound inspection device 26 hits the lining surface 2a a predetermined number of times to perform the hammering sound inspection.

Next, by the photographing device 25 for secondary inspection,
An image of a portion including the damaged lining surface 2a is taken, and the distance from the turning center of the turning body 10 to the damaged lining surface 2a is more accurately measured by an ultrasonic sensor (not shown). Then, the inspection data of the hitting result, the still image, and the distance are recorded in a recording device (for example, a magneto-optical disk is used) in the operation room H, and the lining surface 2a is repaired based on the inspection data. Do.

The operation status of the entire apparatus is monitored by the monitoring camera 8.
It is monitored at any time by b and used as a reference for cleaning and inspection work. In this manner, most of the work of inspecting and cleaning the lining surface 2a inside the chimney 2 can be performed automatically and without introducing an operator to the inside of the chimney 2, and therefore, the attachment to the lining surface 2a can be performed. Work in a bad environment where the kimono is floating can be eliminated. Then, the operator operates the operation room H
The lining surface 2 of the chimney 2 can be operated in an extremely sanitary environment simply by operating the control device 18 and the winch device W in the interior.
a cleaning and inspection work can be performed.

In addition, since the cleaning and inspection work by the operator at a high place is eliminated, the cleaning and inspection of the lining surface 2a of the chimney 2 can be performed safely. Further, since the driving of the entire apparatus is controlled by the control device, accurate and accurate inspection can be performed, and the inspection result is stored as an image or a numerical value in the recording device, so that the inspection result can be easily processed. become.

Here, the above-described protective device 5 used when assembling the cleaning and checking device 1 as described above will be described with reference to the enlarged views of the main parts of FIGS. 1, 7 and 8.
