Description

Technical Field

[0001] The utility model relates to the technical field of risk management of fastening systems, in particular to a monitoring system. Background Art

[0002] In order to identify whether the fastening system fixed on the ceiling or dome is still in an effective state, the existing technology generally relies on manual regular on-site inspection. For example, the upper brackets of trains and subway tunnels (including power systems, water pipes or contact network systems, etc.) have a great risk of loosening and failure due to the dual effects of vibration caused by long-term reciprocating operation of trains and train piston wind, such as fatigue fracture of some parts of the fastening system, bond failure of chemical anchors, cracking of concrete, and displacement of the bolted structure itself.

[0003] The existing inspection technology mainly determines whether there is displacement based on the relative position of the nut relative to the mark of the bolted structure. There are also methods of taking photos for comparison, but they still rely on manual analysis and judgment of the captured images. Both of the above solutions rely solely on the naked eye of the staff, which is bound to cause a lot of high-intensity repetitive labor. With the generation of massive data, the recognition rate decreases and the missed detection rate increases due to visual fatigue, this kind of manual inspection is actually unreliable; there are also technical solutions that consider using computer software to identify the above video images, but when the displacement of the nut is small or it just moves one circle, it is still difficult to accurately identify it, which makes the corresponding risks continue to exist.

[0020] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by terms such as “upper”, “lower”, “left”, “right”, “inside”, “outside”, “front”, “back”, “lateral” and “vertical” are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention. They do not indicate or imply that the device or component referred to must have a specific direction and therefore should not be understood as a limitation on the present invention.

[0022] It should be specially explained that the terms “horizontal” and “vertical” in the present invention are used to illustrate a rough positional relationship, rather than a strict “horizontal plane” or “vertical plane”.

[0023] like Figure 1 and Figure 2 As shown, a monitoring system of a preferred embodiment is shown, which is applicable to a fastening system. The fastening system includes a fixed part 2 attached to a mounting surface 1 and one or more bolt structures 3 fixing the fixed part 2 to the mounting surface 1. The monitoring system includes an inclination meter 4, which is arranged on the fixed part 2. The inclination meter 4 is used to monitor the angle change between the fixed part 2 and the mounting surface 1 to determine whether the fastening system fails.

[0024] Furthermore, the fixed part 2 can be effectively fixed at a specified position of the mounting surface 1 by means of a plurality of bolt structures 3, and at this time, the position of the fixed part 2 is an initial position, which is preferably a horizontal position; when the inclinometer 4 is enabled, it will obtain the angle change of the fixed part 2 relative to the mounting surface 1 in real time or periodically, that is, when the fastening system fails, the fixed part 2 will at least partially displace relative to the above-mentioned initial position, especially in the vertical direction, so that the angle of the fixed part 2 itself relative to the mounting surface 1 changes, and whether the fastening system fails can be judged based on the angle change.

[0025] Preferably, when the angle between the fixed part 2 and the mounting surface 1 does not change or its change is within the allowable range, the fastening system is judged to be effective; when the angle between the fixed part 2 and the mounting surface 1 changes or its change exceeds the allowable range, the fastening system is judged to be failed, and the staff 7 should perform maintenance accordingly.

[0026] Further, as a preferred embodiment, the bolt structure 3 can be a bolt or an anchor bolt or other types of bolted structures.

[0027] Furthermore, as a preferred embodiment, the failure of the fastening system may be: the bolt structure 3 is displaced or detached relative to the mounting surface 1 due to its own deformation or breakage, or the chemical bonding between the bolt structure 3 and the mounting surface 1 fails, or the base structure such as a concrete structure on which the mounting surface 1 is located causes its own quality problems, resulting in the displacement or detachment of the bolt structure 3, or the nut of the bolt structure 3 is loosened due to rotation.

[0028] Further, as a preferred embodiment, when the fastening system fails, the contact position between at least one bolt structure 3 and the fixed part 2 changes relative to the mounting surface 1. Further, the bolt structure 3 has at least one contact portion, and the position where the contact portion contacts the fixed part 2 is the above-mentioned contact position, and the contact portion preferably provides a vertical upward supporting force so that the fixed part 2 is fixed at the mounting surface 1.

[0029] Preferably, the contact portion is formed at the upper end of the nut of the bolt structure 3. The above-mentioned change in contact position relative to the mounting surface 1 may be that the portion of the bolt structure 3 that is in contact with the fixed member 2 changes in the vertical direction, that is, the bolt structure 3 and at least a portion of the fixed member 2 are displaced simultaneously; or the contact portion of the bolt structure 3 and the fixed member 2 at the initial position no longer keeps contact with the fixed member 2, and the bolt structure 3 itself is displaced.

[0030] Further, as a preferred embodiment, the fixed member 2 is preferably an anchor plate structure, and a plurality of bolt structures 3 are used to jointly fix the anchor plate structure to the mounting surface 1, and the lower end of the anchor plate structure may be additionally provided with a lifting bracket for train and subway tunnel elevated systems.

[0031] Further, as a preferred embodiment, the lower surface of the anchor plate structure is formed with at least one mounting surface, and the mounting surface is used for mounting the inclinometer 4 .

[0032] Further, as a preferred embodiment, the above-mentioned mounting surface is preferably extended in a horizontal direction.

[0033] Furthermore, as a preferred embodiment, the size of the above-mentioned anchor plate structure in the horizontal direction is preferably 30cm*30cm; preferably, when at least one bolt structure 3 is displaced by 0.1mm in the vertical direction, the inclination meter 4 should have an angular resolution of at least 0.02° to achieve precise monitoring.

[0034] Further, as a preferred embodiment, the inclinometer 4 is an electronic inclinometer. Further, by fixing the electronic inclinometer on the fixed part 2, the electronic inclinometer moves along with at least a part of the fixed part 2, thereby obtaining the angle change of the fixed part 2 relative to the mounting surface 1.

[0035] Further, as a preferred embodiment, it also includes: a data storage device, which is at least connected to the inclination meter 4 in communication, and the data storage device is used to store angle changes. Further, by storing the angle change data obtained by the inclination meter 4 in the data storage device, it can record all historical change data since the monitoring system is activated, which is conducive to further evaluation. For example, when all bolt structures 3 fail, the angle between the fixed part 2 and the mounting surface 1 may not change in the end, but the fixed part 2 still has displacement relative to the initial position; however, in the above case, the range of motion of the fixed part 2 itself will increase, that is, when external vibration or other force is transmitted to the fixed part 2, the fixed part 2 will still move at a certain moment in the process, so that the inclination meter 4 obtains the corresponding angle change data; in addition, considering that in actual use, the failure of multiple bolt structures 3 generally does not occur at the same time, but gradually occurs at multiple moments in the process, so further evaluation of the above historical change data will also help the staff 7 to find failure problems.

[0036] Furthermore, as a preferred embodiment, it further comprises: a display device 5, which is connected to the inclinometer 4 in communication, and is used to display the current angle change. Furthermore, the display device 5 allows the staff 7 to directly observe the angle change, which is convenient for recording and analysis.

[0037] Further, as a preferred embodiment, when the inclinometer 4 is an electronic inclinometer, the display device 5 is preferably a display screen arranged at the lower end of the electronic inclinometer.

[0038] Furthermore, as a preferred embodiment, it further comprises: a communication device 6, which is connected to the electronic inclination sensor via wired or wireless communication. Furthermore, the staff 7 can easily obtain the angle change data obtained by the current electronic inclination sensor or query the historical record data of the data storage through the communication device 6.

[0039] Furthermore, as a preferred embodiment, the electronic inclination sensor is built-in or externally connected with a corresponding power supply unit and a communication unit to realize the functions of power supply and communication with the outside world.

[0040] Furthermore, as a preferred embodiment, the above-mentioned communication device 6 can be a portable mobile phone or other dedicated communication device 6, or a computer configured with a corresponding management system program, etc.

[0041] Furthermore, as a preferred embodiment, it also includes: an alarm device, which is connected to the inclination meter 4 in communication, and is used to alarm when the fastening system is judged to be failed. Furthermore, the alarm device can realize the alarm function through sound, light, communication, etc., so as to immediately notify the staff 7 of the occurrence of the failure problem of the corresponding fastening system.

[0042] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention.

[0043] The utility model also has the following implementation methods based on the above:

[0044] In a further embodiment of the present invention, the inclination meter 4 is a bubble level. Further, the installation cost can be reduced by providing the bubble level, and no external or internal power supply is required.

[0045] In a further embodiment of the present invention, the bubble level has at least one display surface, which is used to display the position of the bubble in the bubble level. Further, the display surface is preferably formed at the lower end of the bubble level, and the display surface made of a transparent material facilitates the staff 7 to directly observe the bubble position at the display surface.

[0046] In a further embodiment of the utility model, corresponding scale lines may be provided on the display surface to facilitate the determination of the position change of the bubble. Preferably, the setting of the scale lines can directly reflect the current angle change value.

[0047] In a further embodiment of the utility model, it further comprises: an image acquisition device, which is used to acquire the position of the bubble. Furthermore, the image acquisition device can also directly take a photo or video of the display surface or the display device 5 to acquire the corresponding angle change data.

[0048] In a further embodiment of the present invention, the image acquisition device is a camera.

[0049] In a further embodiment of the present invention, the camera is preferably a component of a high-resolution camera system.

[0050] In a further embodiment of the present invention, the above-mentioned camera can preferably be installed at each or each of a plurality of fastening systems, or only one camera can be installed via one mobile device.

[0051] In a further embodiment of the utility model, the mobile device is preferably a mobile cart, which can be moved to pass directly under a fastening system or multiple fastening systems, and the camera is installed on the mobile cart.

[0052] In a further embodiment of the present invention, the inclination meter 4 is an accelerometer. Further, when the fastening system fails, the fixed part 2 will at least partially displace in the vertical direction, and at least the acceleration will change. At this time, through the real-time monitoring of the acceleration change of the fixed part 2 by the accelerometer, the user can obtain the corresponding state change of the fastening system through the information obtained by the accelerometer.

[0053] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention.
