[0034] As Figure 1-7 shown, this embodiment provides a vibration monitoring device for a building covering a subway, including an instrument body and multiple groups of vibration sensors 3. The instrument body includes a vibration measurement main component 1 and a monitoring host 2 installed on the surface of the vibration measurement main component 1. The vibration measurement main component 1 is fixed on the covering building. A number of annularly arranged mounting grooves 101 are equally angled on the periphery of the vibration measurement main component 1. The vibration sensors 3 are detachably connected to the mounting grooves 101, and the vibration sensors 3 are electrically connected to the monitoring host 2 through plug-in connectors. By installing the vibration sensors 3 in the corresponding mounting grooves 101, vibration can be measured in a certain direction.

[0035] The vibration monitoring device of this embodiment installs multiple groups of vibration sensors 3 through the vibration measurement main component 1. Since the vibration sensors 3 are detachably connected to the mounting grooves 101, the staff can install the vibration sensors 3 in different positions on the vibration measurement main component 1 according to needs, thereby realizing multi-point monitoring operations, with flexible operation, which can greatly reduce the work burden and improve the monitoring efficiency.

[0036] Optionally, in a possible implementation manner, the vibration measurement main component 1 is in a disc shape, and an annular scale line 7 is provided at a position on the surface of the vibration measurement main component 1 close to the mounting grooves 101. The scale line 7 is arranged around the monitoring host 2 with the monitoring host 2 as the center. The position of the abnormal vibration source can be accurately distinguished and identified through the scale line 7.

[0037] Optionally, in a possible implementation manner, the vibration sensors 3 are plugged and connected to the mounting grooves 101 through mounting parts 4. The mounting parts 4 are fixedly connected to the side surfaces of the vibration sensors 3. The mounting parts 4 are adapted to the mounting grooves 101, and the cross-sections of the mounting parts 4 and the mounting grooves 101 are semi-circular or rectangular cross-sections, which is convenient for the staff to assemble and improves the operation efficiency.

[0038] Optionally, in a possible implementation, the interior of the installation groove 101 is convex, and the top of the installation groove 101 covers the edge of the installation part 4. The installation groove 101 with this structure can achieve the preliminary positioning of the installation part 4 and improve the assembly efficiency.

[0039] Optionally, in a possible implementation, four locking holes 102 arranged in a rectangular or trapezoidal shape are provided on the installation groove 101. A limit screw for locking the installation part 4 is provided in the locking hole 102. An adhesive structure is provided on the bottom surface of the main vibration measuring part 1. The adhesive structure is composed of a base layer and an adhesive layer. The base layer is preferably made of foam or silica gel or rubber. The adhesive layer covers the surface of the base layer and adheres to the wall surface of the building to be measured through the adhesive layer. Since the base layer has deformability, when pressing the instrument body forcefully, the base layer squeezes the adhesive layer, and the base layer adheres to the building more tightly through the adhesive layer.

[0040] Optionally, in a possible implementation, an avoidance groove 6 is formed on the bottom surface of the vibration measuring instrument 3, and a bottom plate 5 is detachably installed in the avoidance groove 6. The bottom plate 5 is connected to the vibration measuring instrument 3 by screwing or clamping. A detection element is also provided at the bottom of the vibration measuring instrument 3. When the vibration measuring instrument 3 is installed in the installation groove 101, the detection element is in close contact with the building, and the bottom surface of the bottom plate 5 is on the same horizontal plane as the bottom surface of the main vibration measuring part 1. The subway superstructure is vibration-detected through the detection element, and the vibration detection values are transmitted to the monitoring host 2. Through the setting of multiple installation grooves 101 and installation parts 4, multi-point detection work can be realized. The data detected by multiple vibration measuring instruments 3 are transmitted to the monitoring host 2. A signal transmission element is installed in the monitoring host 2, and it can be wirelessly transmitted to the terminal system of the building management, which is convenient for the vibration prediction work of the subway superstructure. For example, if the rightmost vibration measuring instrument 3 is instrument a, then the vibration measuring instruments 3 arranged in a counterclockwise order with instrument a as the first are instrument b, instrument c, instrument d... Each vibration measuring instrument 3 is named separately in the monitoring host 2. For example, when instrument b detects a strong vibration feeling, the terminal system of the building management can receive an instruction, quickly identify the vibration detection position of the corresponding vibration measuring instrument 3, and can take protective measures in time.

[0041] Optionally, in a possible implementation, an avoidance groove 6 is formed on the bottom surface of the vibration measuring instrument 3, and an adhesive structure is detachably installed in the avoidance groove 6. The vibration measuring instrument 3 is fixed on the superstructure through the adhesive structure.

[0042] During use, the staff can separate the vibration measuring instrument 3 from the installation groove 101, remove the bottom plate 5 from the bottom of the vibration measuring instrument 3, stick the adhesive structure to the bottom wall of the avoidance groove 6, and then use the adhesive structure to install the vibration measuring instrument 3 separately on the building. The staff can flexibly separate individual vibration measuring instruments 3 from the main vibration measuring part 1 according to needs. At this time, the vibration measuring instrument 3 is fixed on the superstructure through the adhesive structure, thereby increasing the monitoring range and having strong overall practicability.

[0043] Obviously, the above embodiments are merely examples given for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
