[0037] Among them, the shell 2 is placed on one side of the wall 1, the infrared laser rangefinder 3 is arranged on one side of the shell 2, the receiving plate 4 is arranged on one side of the infrared laser rangefinder 3, the intelligent controller 5 is arranged on the outside of the shell 2, the mobile chassis 6 is arranged below the shell 2, the flip plate 7 is arranged inside the shell 2, the folding plate 8 is rotatably connected to one end of the flip plate 7, and the infrared laser rangefinder 3 is arranged on the folding plate 8. The mobile chassis 6 is provided with a motor and a roller inside, and the motor is started by the intelligent controller 5 to drive the roller to rotate and drive the shell 2 to move; the intelligent controller 5 is connected to the host computer and issues a control instruction; the shell 2 is moved to the vicinity of the measuring wall 1 through the mobile chassis 6; the flip plate 7 rotates, thereby driving the infrared laser rangefinder 3 to emit infrared lasers upward and downward in turn, respectively, to the ceiling and the ground, and then measure the height of the wall 1; the folding plate 8 is folded, and then the infrared laser rangefinder 3 is aimed at one side of the wall 1, and the laser distance measurement is emitted, so that the length of the wall 1 can be measured; the folding plate 8 is reset, and the width of the wall 1 is clamped by the folding plate 8 and the receiving plate 4, and then the infrared rays are emitted on the receiving plate 4 to measure the thickness of the wall 1.

[0038] Secondly, the plurality of lifting components 9 are sequentially arranged above the mobile chassis 6, the output ends of the plurality of lifting components 9 are fixedly connected to the outer shell 2, the flipping driving component 10 is arranged inside the outer shell 2, the output end of the flipping driving component 10 is fixedly connected to the flip plate 7, and the folding driving component 11 is arranged at the connection between the folding plate 8 and the flip plate 7. The lifting component 9 is a cylinder, the flip driving component 10 is a motor, and the folding driving component 11 is a self-locking motor; when the lifting component 9 is started, it can drive the shell 2 to adjust the height, and then measure the thickness and length of the wall 1 at different heights to ensure the accuracy of the data. At the same time, if it is found that the data of the wall 1 at different heights are different, it means that the wall 1 is uneven. When the flip driving component 10 is started, it can drive the flip plate 7, the folding plate 8 and the infrared laser rangefinder 3 to flip, and the folding driving component 11 can drive the folding plate 8 to rotate on the flip plate 7 to fold.

[0039] At the same time, the internal monitoring unit is arranged inside the shell 2; the shell 2 has two slide grooves 18, the screw machine 12 is arranged inside the shell 2, the moving block 13 is arranged at the output end of the screw machine 12, the two sliders 14 are symmetrically arranged at both ends of the moving block 13, the sliders 14 are slidingly connected to the slide grooves 18, the rotating mechanism is arranged on one side of the moving block 13, the two clamping plates 15 are symmetrically arranged on both sides of the receiving plate 4, the knocking block 16 is arranged on the corresponding clamping plate 15, the sound receiver 17 is arranged on one side of the knocking block 16, and the ultrasonic detection unit is arranged below the shell 2.

Then the rotating mechanism is started, driving the receiving plate 4 to rotate, so that the knocking block 16 is aligned with the wall 1. Through the repeated movement of the moving block 13, the knocking block 16 knocks on the wall 1. At the same time, the sound receiver 17 collects the knocking sound, and transmits the sound data to the host computer through the intelligent controller 5. The host computer server stores the sound of the existence of holes or cracks in the wall 1, compares the sound data with the data in the server, and then analyzes whether there are holes and cracks inside the wall 1. At the same time, cooperate with the ultrasonic detection unit to perform ultrasonic detection on the inside of the wall 1 to further detect the internal holes and cracks.

[0040] In addition, the rotating component 19 is arranged on one side of the moving block 13, and the two gears 20 are arranged on one side of the moving block 13 in sequence.

One end of the receiving plate 4 is fixedly connected to one end of the rotating shaft 21, and the other end of the rotating shaft 21 is rotatably connected to the moving block 13. The limiting component is arranged on the rotating shaft 21. The rotating component 19 is a motor. When the rotating component 19 is started, it drives the gear 20 to rotate, drives the rotating shaft 21 to rotate, makes the receiving plate 4 rotate, and finally drives the clamping plate 15 to rotate. The limiting component can limit the rotating shaft 21 so that it cannot rotate, and then the wall 1 can be knocked.

The limiting block 23 and the limiting hole 25 are adapted to each other. When the limiting cylinder 22 is started, the limiting block 23 is driven to move so that the limiting block 23 enters the limiting hole 25, thereby limiting the limiting plate 24, so that the rotating shaft 21 cannot rotate.

[0042] Again, the pushing component 26 is disposed below the housing 2, and the output end of the pushing component 26 is fixedly connected to the ultrasonic detector 27. The pushing component 26 is a cylinder, and the pushing component 26 drives the ultrasonic detector 27 to approach the wall 1, and uses ultrasonic waves to detect cavities and cracks inside the wall 1.

The camera 28 can take a picture of the knocked wall 1, and then transmit the picture back to the host computer, so as to observe whether there are cracks on the outside of the wall 1. If there are cracks, it means that the quality is unqualified. The moving part 29 is an electric slide rail. When the moving part 29 is started, it drives the abutting plate 30 to move, and moves to one side of the folding plate 8 through the abutting plate 30, and then when the folding plate 8 and the receiving plate 4 clamp the wall 1, the folding plate 8 is abutted and supported to improve stability.

[0044] Finally, the anti-skid unit is arranged on the mobile chassis 6; the telescopic component 31 is arranged above the mobile chassis 6, the output end of the telescopic component 31 passes through the mobile chassis 6 and is fixedly connected to the lifting plate 32, and a plurality of anti-sliding blocks 33 are sequentially arranged below the lifting plate 32. The telescopic component 31 is a cylinder, and when the telescopic component 31 is started, the lifting plate 32 is driven to move downward, so that the anti-sliding block 33 contacts the ground, thereby increasing friction and avoiding slipping and inaccurate measurement.

The host computer server stores the sound of the existence of holes or cracks in the wall 1, and compares the sound data with the data in the server to analyze whether there are holes and cracks inside the wall 1. At the same time, in conjunction with the ultrasonic detection unit, ultrasonic detection is performed on the inside of the wall 1, thereby fully exploring the internal holes and cracks, and further ensuring the safety of the building structure; through the above-mentioned structural setting, the infrared laser rangefinder 3 can be moved and folded and turned over at the same time, so that the wall 1 can be fully measured to avoid the dead angles on the back and height that cannot be measured, and the interior of the wall 1 can be deeply detected, the external cracks can be photographed and inspected, and the building structure can be fully detected to fully ensure the safety of the building structure.
