[0002] CN220751595U discloses a steel structure fatigue damage detection device, which ensures the overall automatic movement along the steel structure surface for detection through the setting of rotating magnetic suction movement; increases the overall adsorption force on the steel structure surface through the setting of suction and dust removal with negative pressure suction; and increases the accuracy of steel structure fatigue damage detection by rotating and cleaning the dust on the steel structure surface. The above device performs flaw detection health monitoring by moving on the steel structure, but in the actual construction process of steel structure buildings, it is difficult to have a steel structure of sufficient length, straight and unobstructed for the above device to perform mobile monitoring. At the same time, due to the limitation of movement, the above device also has monitoring blind spots, and in larger steel structure buildings, multiple monitoring is required. The above device is relatively bulky and lacks flexibility in use, and it is difficult to meet actual use needs. Summary of the invention

[0003] The present invention provides a BIM-based assembled steel structure building health monitoring device with a detection head isolation protection function, which solves the problems existing in the prior art.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

The mounting tube is movably sleeved on the outer side of the top end of the probe rod. The outer wall of the mounting tube is provided with a first through groove. The top outer side of the mounting tube is fixedly sleeved with a driving disk. The driving disk is connected to the protective tube bearing.

[0023] On the basis of the above structure, the monitoring instrument 1 is electrically connected to the probe rod 3 via the connecting wire 2 , and the probe rod 3 is electrically connected to the ultrasonic flaw detector 4 .

[0024] In this embodiment, by setting up the connecting wire 2, the health monitoring result of the steel structure by the ultrasonic flaw detector 4 can be fed back to the monitor 1 in time, so that the staff can deal with it in time.

[0025] Based on the above structure, one end of the connecting wire 2 passes through the bottom of the sleeve 5 and is slidably connected to the sleeve 5. A third through groove 13 is opened on the right outer wall of the bottom of the sleeve 5, and a spring 10 is fixedly connected between the bottom end of the probe rod 3 and the inner bottom of the sleeve 5.

[0026] In this embodiment, the spring 10 is provided to facilitate the automatic retraction and reset of the probe rod 3 and the ultrasonic flaw detector 4 after the handle 12 is released.

[0027] On the basis of the above structure, the opening and closing control component 8 includes a mounting tube 81, a first through groove 82, a driving disk 83 and a second through groove 84. The mounting tube 81 is movably sleeved on the outer side of the top end of the probe rod 3. The first through groove 82 is provided on the outer wall of the mounting tube 81. The driving disk 83 is fixedly sleeved on the outer side of the top end of the mounting tube 81. The driving disk 83 is connected to the bearing of the protective tube 6. Second through grooves 84 are provided inside the left and right ends of the driving disk 83. The two second through grooves 84 are symmetrical about the center point of the center of the driving disk 83.

[0028] In this embodiment, when the probe rod 3 is raised or lowered, the two sets of protective cleaning components 9 can be automatically opened and closed by the opening and closing control component 8.

[0029] Based on the above structure, the end of the fixed column 7 away from the probe rod 3 is guided and slid in the first through groove 82. The first through groove 82 includes a vertical section and an inclined section at the bottom of the vertical section, and the inclined section is connected to the vertical section.

[0030] In this embodiment, by utilizing the inclined section at the bottom of the first through groove 82, when the probe rod 3 is raised, it is convenient to squeeze the inclined section of the first through groove 82 through the fixed column 7, so that the mounting tube 81 and the driving disk 83 can be controlled to rotate, thereby facilitating the protective cleaning assembly 9 to move and open.

[0031] Based on the above structure, the protective cleaning assembly 9 includes a protective plate 91, a cleaning pad 92, a cross bar 93 and a vertical bar 94.

[0033] On the basis of the above structure, the bottom end of the vertical rod 94 extends into the second through slot 84 , and the protective plate 91 forms a horizontal sliding structure through the driving disk 83 .

[0035] The working principle of the present invention is as follows:

[0036] When in use, first turn on the monitor 1, hold the bottom of the sleeve 5 and lift it up, so that the cleaning pad 92 bonded to the top of the protective plate 91 is in contact with the position to be monitored on the steel structure, then squeeze the handle 12, and the push rod 11 can push the probe rod 3 to drive the ultrasonic flaw detector 4 to rise. At this time, the fixed column 7 on the outer wall of the top of the probe rod 3 can squeeze the bottom inclined section of the first through groove 82, so that the mounting tube 81 and the driving disk 83 can be rotated, and the second through groove 84 can be used to push the left and right vertical rods 94 to control the two groups of protective cleaning components 9 to move in directions away from each other, so that the top of the protective tube 6 can be opened. When the fixed column 7 moves in When the first through slot 82 is inserted into the vertical section, the opening and closing control component 8 and the protective cleaning component 9 are stationary, and the probe rod 3 continues to rise until the ultrasonic flaw detector 4 is extended from the protective tube 6. The ultrasonic flaw detector 4 is used to conveniently monitor the flaw detection health of the steel structure, and the monitoring results can be fed back to the monitor 1 in time through the connecting wire 2, which is convenient for the staff to deal with it in time. Moreover, when the protective cleaning component 9 is moved and opened, the cross bar 93 can be used to improve the stability of its sliding opening and closing, and the cleaning pad 92 can also be used to wipe and clean the position to be tested of the steel structure to avoid dust adhesion and affect the accuracy and reliability of the detection results;

[0037] After completing the health detection of the steel structure, release the handle 12. At this time, the handle 12, the push rod 11 and the probe rod 3 can be reset by the spring 10, and the ultrasonic flaw detector 4 can be stored in the protective tube 6. At the same time, two sets of protective cleaning components 9 can be used to close the top opening of the protective tube 6, so as to isolate and protect the ultrasonic flaw detector 4 and avoid damage. Compared with the comparative documents, this device adopts a handheld monitoring method, which is lighter to carry and more flexible to use. It is suitable for monitoring various positions of assembled steel structures, can reduce detection blind spots, and is more practical.
