Description

Technical Field

[0001] The present invention belongs to the technical field of pipeline anti-seismic auxiliary supports, and in particular relates to a system capable of real-time monitoring of pressure changes in anti-seismic support component parts to implement early warning. Background Art

[0002] Existing components such as cable ducts or air ducts used on the top of buildings are made by first inserting expansion wire sleeves into the ceiling (ceiling) and connecting the expansion wires as hangers. The connection strength is very weak. When an earthquake occurs, the building will swing, and the pipes and cables installed on the top of the building will also swing. This component swing will not disappear by itself, and the swing amplitude of the component will gradually increase with the swing of the building, and may even resonate with the swing of the building. Repeated high-intensity swinging will cause damage to the fixed parts of the pipeline components, and then cause damage to the pipeline components and important components inside them, expanding the extent of earthquake damage.

[0003] The existing solutions for solving the above problems are mostly through the method of reinforcing the pipeline fixing components. For example, the seismic support with publication number CN208670283 U is the most typical. This solution includes a first support rod extending perpendicular to the axial direction of the pipeline, a second support rod extending obliquely along the axial direction of the pipeline, and a third support rod extending along the radial direction of the pipeline. The seismic support also includes a pipe clamp assembly sleeved on the pipeline, the pipe clamp assembly includes a first pipe clamp and a second pipe clamp arranged adjacent to each other, and the first pipe clamp and the second pipe clamp are both sleeved on the pipeline; one end of the first support rod and the third support rod are respectively fixedly connected to the first pipe clamp, and the other end is respectively fixedly connected to the mounting surface, one end of the second support rod is fixedly connected to the second pipe clamp, and the other end is fixedly connected to the mounting surface; a fourth support rod is also connected between the first support rod and the second support rod, and a fifth support rod is also connected between the first support rod and the third support rod. It can be seen that the seismic support provided by this scheme mainly improves the strength of the pipeline fixing components from a three-dimensional perspective, so that the fixed ends of the pipeline fixing components become multiple, and the pipeline is pulled from different angles. Although this scheme has a certain seismic effect, it still has a strength limit. The components are in a rigid connection and have no shock absorption or damping function. When the magnitude is high, due to the large gravity of the pipeline components, simply relying on improving the strength of the pipeline fixing components still has disadvantages. The deformation coordination and adaptive adjustment capabilities of the entire pipeline are poor. When the building swings at a large frequency and the amplitude increases with the number of swings, the constraint limit of the connection strength of the pipeline components will be exceeded, which will cause greater damage.

[0004] Therefore, the method of fixing the pipeline components by pulling from multiple angles can significantly improve the stability of the pipeline components, but it has a strength limit. When this limit is exceeded, it often causes greater damage. If the strength is improved by increasing the amount of material used for the fixed components, such as increasing the thickness of the material, the construction cost will be greatly increased. The number of hanging parts used to fix the pipeline components is huge. In order to prevent accidental events, it is obviously less feasible to take the approach of generally increasing costs, especially in the current situation of fierce market competition. By generally increasing costs, the market share will be greatly reduced, which is not conducive to the normal and sustainable development of enterprises. The existing shock-absorbing bracket components still need to be improved. Summary of the invention

[0014] Beneficial effects of the present invention: The present invention adds a warning rod with shock absorption and damping effects to the seismic support. By installing EMES pressure sensors or matching sensors at the pressure parts of each rod containing a strong spring, the pressure changes of each pressure part can be monitored in real time through the control system, and even the displacement changes of each rod can be monitored. When the change amplitude is greater than the set threshold, a warning signal is issued through the controller or cloud monitoring system, thereby providing an automatic warning function.

[0015] The present invention applies thrust to the centers of the traction ends at both ends of the supporting crossbeam respectively and applies balanced pulling force around the thrust at the same time, and utilizes the interaction between the thrust and pulling force to increase the prestressed thrust to the top rod assembly providing the thrust, and to provide prestressed pulling force to the traction components providing the pulling force, so that the traction ends at both ends of the supporting crossbeam are in a stress state. When there is swing in this state, the corresponding tensile repulsive force needs to be overcome first. Therefore, the structure can well improve the stability of the supporting crossbeam, thereby improving the stability of the pipeline component.

[0016] When the swing amplitude and frequency exceed the tension-repulsion limit, the present invention can also provide buffering through the strong springs provided by each traction component or the push rod assembly to achieve the effect of energy dissipation, thereby further improving the stability of the supporting beam and the pipeline component.

[0017] The present invention has various and simple adjustment modes, is easy to operate, and has good use effects. Since each traction component has a buffering function, each traction component can dissipate energy by itself to prevent hard damage, so the consumables of each traction component are relatively small, thereby reducing production costs.

[0018] The present invention can provide forces to the supporting crossbeams and pipeline components at multiple angles, and the top rod assembly and each traction component can be hinged at the upper and lower ends, thereby providing a structural relationship of the supporting crossbeams and pipeline components that are movably connected, ensuring that there are no stress concentration areas on the supporting crossbeams and pipeline components, thereby having the characteristics of stability and not being easily damaged, and having a long service life.

When the threshold value is exceeded, an alarm is issued, thereby realizing the early warning function of the seismic support.

The fixed structure of the combined sphere used in this embodiment, by setting an enlarged ball cavity inside the joint of the combined sphere and matching the sub-sphere 12, can well constrain the connection of each sub-sphere 12, but does not constrain the swing of each rod, so that each rod can rotate or swing independently and freely.

A sensor lead hole 913 is set on the supporting wall 904. The upper end of the middle push rod is connected to the ceiling, and the middle push rod is used to support the traction end. The upper ends of each pull rod are respectively fixed to the ceiling through an articulated seat (for example, through a universal joint and a connecting fixed seat 27 and the fixed seat is fixed by an expansion wire). The lower ends of the middle push rod and each pull rod are respectively connected to the combined sphere, and each pull rod provides a balanced traction force to the traction end, so that each pull rod forms a repulsive relationship with the middle push rod at its corresponding center, and the signal line of each pressure sensor is connected to the controller or the input end of the cloud system to form an early warning system.

[0050] This embodiment applies thrust to the center of the traction ends at both ends of the supporting beam and applies balanced tension around the thrust at the same time, and utilizes the interaction between the thrust and tension to increase the prestress thrust to the top rod assembly that provides the thrust, and provide prestress tension to the traction components that provide the tension, so that the traction ends at both ends of the supporting beam are in a stress state. When there is swing in this state, the corresponding tensile repulsive force needs to be overcome first. Therefore, this structure can well improve the stability of the supporting beam, thereby improving the stability of the pipeline component.

[0051] This embodiment installs EMES pressure sensors or matching sensors at the pressure parts of each rod containing a strong spring, and can monitor the pressure changes of each pressure part in real time through the control system, and even monitor the displacement changes of each rod. The pressure sensor preferably adopts a MEMS pressure sensor, and each group of brackets can be further equipped with a MEMS accelerometer or MEMS gyroscope along with the MEMS pressure sensor to sense the displacement changes of the bracket and issue an early warning. The control system for receiving each pressure sensor and sending it to a speaker or indicator light to provide an alarm is a common known technology and will not be described in detail. When the amplitude of the change is greater than the set threshold, a warning signal is issued by the controller or cloud monitoring system, thereby providing an automatic early warning function. When the swing amplitude and frequency exceed the tension repulsion limit, the present invention can also provide a buffer through the strong springs provided by each traction component or the top rod assembly to achieve the effect of energy dissipation, so that the stability of the supporting beam and the pipeline component can be further improved.
