A clamping block 8 is installed at the lower end of the quick mounting component 7, and a vibration sensor 11 is also installed in the quick mounting component 7. At present, steel structures are required in large-span buildings. When reinforcing a building, it is necessary to monitor the support of the steel structure for safety reasons. Workers clamp the monitoring device to the load-bearing steel structure (rectangular steel structure) by installing the handle 3, wherein the shape of the detection device changes according to the shape of the load-bearing steel structure.

[0044] According to some embodiments of the present application, Figure 8-Figure 10As shown, the lower end of the rotating plate 710 is fixedly connected to an extension plate 711, and a limiting groove 712 is provided in the middle of the extension plate 711. A second limiting rod 716 is installed in the limiting groove 712, and the second limiting rod 716 is fixedly connected to the lower end of the fixed leg 6. The lower end of the extension plate 711 is fixedly connected to a mounting sheet metal 713, and a second mounting block 714 is rotatably installed in the mounting sheet metal 713. The lower surface of the second mounting block 714 is fixedly connected to a clamping block 8, and the second Transmission plates 717 are rotatably mounted on both sides of the mounting block 714, and side support rods 707 are rotatably mounted on the upper ends of the transmission plates 717. One end of each side support rod 707 is fixedly connected to a third central axis 718, and each third central axis 718 is rotatably mounted on a fixed leg 6. A connecting piece 706 is fixedly connected to the upper end of each side support rod 707, and the connecting piece 706 is rotatably mounted on the lower end of the first mounting block 704. During the installation process, since most steel structures are square and rectangular The four corners of one side of the steel structure will push against the side support rod 707 and move toward the fixed leg 6, which can drive the No. 1 mounting block 704 to extend to the outside of the mounting shell 702, and the mounting shell 702 is rotated and installed in the bottom mounting plate 12 through the No. 1 central axis 701, so that the No. 1 mounting block 704 and the side support rod 707 are closely attached to the surface of the steel structure. When the No. 1 mounting block 704 is extended, it passes through the fixed block 708 and the connecting sheet metal 709 and is rotated and installed on the rotating plate 710 and the extension plate 711. When the extension plate 711 is installed on the No. 2 limiting rod 716 through the limiting groove 712, the rotating plate 710 and the extension plate 711 can be pushed up and down along the No. 2 limiting rod 716, driving the mounting sheet metal 713 at the lower end of the extension plate 711 to move to the other side of the steel structure, and then through the restraint of the transmission plate 717, the block 8 can be pulled from a vertical state to a horizontal state and form a concave fixing method with the fixed leg 6. This fixing method is quick and firmly fixed, thereby improving the quickness and practicality of the device installation.

[0045] The working principle of this embodiment is:

[0046] First, during the installation process, since most of the columns of steel structures are square and rectangular, the four corners of the steel structure columns will push against the side support rod 707 and move toward the side of the fixed leg 6, which can drive the No. 1 mounting block 704 to extend to the outside of the mounting shell 702, and the mounting shell 702 is rotated and installed in the bottom mounting plate 12 through the No. 1 central axis 701, so that the No. 1 mounting block 704 and the side support rod 707 are close to the surface of the steel structure. When the No. 1 mounting block 704 is extended, it passes through the fixed block 708 and the connecting sheet metal 709 and is rotated and installed on the rotating plate 710 and the extension plate 711. Since the extension plate 711 is installed on the No. 2 limiting rod 716 through the limiting groove 712, the rotating plate 710 and the extension plate 711 can be pushed up and down along the No. 2 limiting rod 716, driving the mounting sheet metal 713 at the lower end of the extension plate 711 to move to the other side of the steel structure, and then through the restraint of the transmission plate 717, it can The card block 8 is pulled from a vertical state to a horizontal state and forms a concave fixing mode with the fixed leg 6. This fixing mode is quick and firmly fixed, thereby improving the quickness and practicality of the device. When the No. 1 mounting block 704 is extended, the circuit board 2 can be close to the surface of the steel structure column, so that the vibration sensor 11 is vertically set on the surface of the steel structure column. Then, by tightening the spring top rod 101, the connecting rod 103 and the fixed bracket 104 can be driven to follow the slider 102 to move in the slide groove 10, thereby driving the sensing block 111 to be close to the sensing end of the vibration sensor. When the steel structure vibrates, the sensing block 111 will vibrate with the steel structure. The spring top rod 101 can make the sensing block 111 return to its position and contact the sensing end of the vibration sensor 11, and then the support spring 109 can support the sleeve 108 and the movable rod 110, thereby achieving the effect of balancing support for the sensing block 111.

[0047] The specific model of the vibration sensor 11 in the embodiment of the present application may be: IR333C; the specific model of the displacement sensor 11 in the embodiment of the present application may be: LTS400-A1.

[0048] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention.
