When the spiral material taking rod takes the material, the motor 48 is started, and the vacuum suction force generated after the motor 48 is started is used to absorb the material taken by the spiral material taking rod and then transport it to the storage bottle 49 for storage. Then the staff can rotate the storage bottle 49 out, take out some wall materials and place them, and then place the storage bottle 49 in the placement groove 46, so that the powder collected in the storage bottle 49 is transported to the pressing cylinder 494 in cooperation with the guide groove 495. Inside, the curing agent and water are injected into the injection port 43 respectively, and transported to the inside of the pressing cylinder 494 and mixed with the collected powder with the cooperation of the delivery pipe 44. Then, under the power supply of the high-efficiency battery pack 17, the drive controller 496 drives the electric push rod 497 to lift and lower back and forth to press and solidify the materials inside the pressing cylinder 494. After that, the staff can open the movable window 45 to take out the solidified cylindrical core column inside the pressing cylinder 494.

[0041] The use method and working principle of the device are as follows: first, when the staff needs to inspect the building structure, the whole structure is pushed and placed in the predetermined position under the action of the wheels 3, and then the travel component 6 is driven out of the placement space 5 under the operation of the display screen 20. Then the staff can place the whole structure of the travel component 6 in the inner groove of the steel beam at a high place or on the ground plane, and use the drive motor to drive the rear drive wheel 12 to rotate, and move forward according to the preset working path. Then the stepper motor 71 is started to drive the screw rod 75 to rotate, so that the dovetail sliding seat 76 slides with the dovetail sliding rail 62 under the cooperation of the dovetail slider, thereby driving the traction rope connection end 81 on the first sliding wheel 82, the second sliding wheel 84 and the third sliding wheel 86 is wound around and rotated inside, and the bevel gear and the driven gear 85 cooperate to form a reduction gear set, so that the handheld pulse generator 10 drives the mounting frame 64 to adjust the angle by 90 degrees under the cooperation of the rotating column 63 and the rotating groove 65, so that the handheld pulse generator 10 forms a vertically opposed state with the steel beam surface or the ground plane under the rotation cooperation of the mounting frame 64, and then the piezoelectric chip inside the detection probe 13 vibrates to generate ultrasonic waves, which are vertically incident on the steel beam or concrete plane. When the ultrasonic wave passes through the steel beam frame or concrete surface, gap and bottom surface in turn, some of the ultrasonic waves are reflected back. These reflected waves have experienced different round trips and return to the detection probe 13, and the detection probe 13 converts them again The electric pulse signal is then amplified by the receiving amplifier 16, and at the same time, the signal other than that transmitted by the receiving amplifier 16 is filtered out by the filter, ensuring that each reflected wave passes through the D / A converter to display the input signal on the display screen 20, which is convenient for the staff to observe. At the same time, during the driving process, using the wide-angle camera 14, the staff can observe the detection operation in real time, so that the signal transmitted by the wide-angle camera 14 is transformed into an analog signal and transmitted to the display screen 20 under the cooperation of the switch 15 and the decoder 18. The overall structure is light and with the cooperation of the high-efficiency battery pack 17, the high-efficiency battery pack 17 adopts a 2500 mAh battery pack to ensure the endurance of the overall operation. While the above structure is performing the detection operation, the staff The water drill 47 can also be taken out from the side chamber shell 41 to perform core drilling detection on the wall. When the spiral material taking rod takes material, the motor 48 is started, and the vacuum suction force generated after the motor 48 is started is used to absorb the material taken by the spiral material taking rod, and then the material is transported to the storage bottle 49 for storage. Then the staff can rotate the storage bottle 49 out, take out some wall materials and place them, and then place the storage bottle 49 in the placement groove 46, so that the powder collected in the storage bottle 49 is transported to the inside of the pressing cylinder 494 with the cooperation of the guide groove 495, and then the curing agent and water are respectively injected into the injection port 43, and transported to the inside of the pressing cylinder 494 with the cooperation of the conveying pipe 44 to mix with the collected powder, and then under the power supply of the high-efficiency battery pack 17,After the driving controller 496 drives the electric push rod 497 to move up and down to press and solidify the material inside the pressing cylinder 494, the staff can open the movable window 45 and take out the solidified cylindrical core column inside the pressing cylinder 494. The solidified cylindrical core column has the same diameter as the hole drilled by the water drill 47 each time, so it is easy to put it into the drilled hole. Then, the damage on the surface is repaired with a paint repair gun, which effectively avoids the need for repairing again in the later stage, which is time-consuming and labor-intensive, and improves the inspection efficiency.
