At this time, the driving motor 3021 rotates, and the vertical plate 4 and the sleeve block 501 are controlled to rotate through the second telescopic rod 3031 and the connecting rod 503. The sleeve block 501 moves down along the threaded rod 2 under the action of the semi-ring plate 5011. The downwardly moved sleeve block 501 pushes the vertical plate 4 to approach the inner wall of the boiler through the connecting rod 503, and the adjustment of the detection equipment is completed.

Both ends of the two rotating shafts 605 are rotatably connected to the inner wall of the protective shell 101, and the ends of the two worm gears 604 are rotatably connected to the inner wall of the protective shell 101. The bidirectional motor 601 is installed on the mounting plate 1 by bolts, and a support plate 603 is movably sleeved on the two connecting shafts 602, and the bottom ends of the two support plates 603 are fixedly connected to the mounting plate 1.

[0025] The bidirectional motor 601 in the lifting assembly 6 works, and its two output ends both drive the fixed connecting shaft 602 to rotate. The two connecting shafts 602 drive the worm 604 to rotate, so that the two worms 604 drive the worm wheels 606 to rotate, and the two worm wheels 606 drive the driving gear 607 to rotate through the rotating shaft 605, so that the tooth surface of the driving gear 607 controls the rack 1022 to move vertically during the rotation process, and the moving rack 1022 drives the U-shaped lifting plate 102 to move, thereby completing the height control of the U-shaped lifting plate 102, which is convenient for better detection of the inner wall of the boiler.

[0026] See also Figure 3 , Figure 5 and Figure 6 As shown, the lateral extension assembly 5 includes a sleeve block 501, which is sleeved on the threaded rod 2. A first mounting seat 404 is fixed to the outer wall of the sleeve block 501. A second mounting seat 502 is fixed to the top of the outer wall of the vertical plate 4 close to the heat insulation shell 302. An inclined connecting rod 503 is provided between the first mounting seat 404 and the second mounting seat 502.

At this time, the two half-ring plates 5011 are connected to form a whole. Then, under the action of the driving motor 3021, the vertical plate 4 drives the sleeve block 501 to rotate through the connecting rod 503. During the rotation process, the half-ring plate 5011 is meshed with the threaded rod 2, and the sleeve block 501 slides along the two T-shaped sliders 3011 through the T-shaped ring groove 504. The sleeve block 501 will move downward along the threaded rod 2, and the downward moving sleeve block 501 will shrink the telescopic ends of the two first telescopic rods 301, and will also push the connecting rod 503 to change its angle through the second mounting seat 502. The connecting rod 503 with changed angle will push the vertical plate 4 to approach the inner wall of the boiler through the first mounting seat 404, and the moving vertical plate 4 will stretch the second telescopic rod 3031 until the sleeve block 501 contacts the fixed plate 3, and the telescopic ends of the two electric telescopic cylinders 5013 shrink, so that the semi-ring plate 5011 is separated from the threaded rod 2. At this time, the vertical plate 4 and the sleeve block 501 will rotate around the threaded rod 2.

At this time, the two semi-ring plates 5011 are connected to form a whole. Then, the external controller starts the driving motor 3021, and drives the rotating block 303 to rotate through the output end. The rotating block 303 drives the vertical plate 4 to rotate through the second telescopic rod 3031, and the vertical plate 4 drives the sleeve block 501 to rotate through the connecting rod 503. During the rotation process, the semi-ring plates 5011 are meshed with the threaded rod 2, and the sleeve block 501 is also connected. 01 will slide along the two T-shaped sliders 3011 through the T-shaped ring groove 504, so that the sleeve block 501 will move downward along the threaded rod 2, and the downwardly moving sleeve block 501 will shrink the telescopic ends of the two first telescopic rods 301, and will also push the connecting rod 503 to change the angle through the second mounting seat 502. The connecting rod 503 with the changed angle pushes the vertical plate 4 to approach the inner wall of the boiler through the first mounting seat 404, and the moving vertical plate 4 stretches the second telescopic rod 3031 until the sleeve block 501 contacts the fixed plate 3, and the telescopic ends of the two electric telescopic cylinders 5013 shrink, so that the semi-ring plate 5011 is separated from the threaded rod 2, and at this time, the vertical plate 4 and the sleeve block 501 will rotate around the threaded rod 2; At this time, the high temperature resistant camera 401, the laser scanner 402 and the ultrasonic flaw detector 403 are started by an external controller. When the vertical plate 4 rotates around the threaded rod 2, the inner wall of the boiler is photographed, scanned and flaw detected and sent to the computer through the transceiver for observation and judgment by the inspection personnel.
