Description

Technical Field

[0001] This utility model relates to the field of load measurement technology, specifically a load measuring device for pipe hanging. Background Technology

[0002] The boiler roof area of ​​a thermal power plant contains numerous hanging devices, suspending components such as boiler headers and pipe banks. During operation, if the pipe support system experiences abnormal load, the load will deviate significantly from the design value. In extreme cases, this can lead to structural damage and hanger failure. Furthermore, when the load at the suspension point fluctuates greatly or is excessive, the pipe stress at the suspension point may exceed the allowable stress of the pipe material, causing pipe cracking and deformation. Therefore, testing and evaluating the load conditions of these hanging devices in the boiler roof area, where headers and pipe banks are densely packed, is essential. Utility Model Content

[0023] Compared with the prior art, the present invention has the following beneficial technical effects:

[0024] This invention provides a load measuring device for pipe hanging. By setting stress detection plates on the bearing component and connecting the bearing component to the top of the pipe hanging device through a support component, the bearing component can perform its load-bearing function normally without affecting the original working state and stress structure of the hanging device. The lifting component is driven by a controller, so that the force on the bearing component gradually increases until the bearing component bears the same load as the hanging device. The strain value is detected by the controller, which improves the accuracy of pipe hanging load measurement.

[0025] Furthermore, the load-bearing assembly includes a load-bearing screw and a connecting sleeve. One end of the load-bearing screw vertically penetrates the support assembly and connects to the connecting sleeve, which in turn connects to the top of the pipe hanging device. The combined design of the load-bearing screw and the connecting sleeve makes the entire load-bearing assembly structurally more stable. The use of the connecting sleeve ensures more even stress distribution on the load-bearing screw, preventing structural damage caused by excessive stress at a single point.

[0027] Furthermore, the support assembly includes two sets of load-bearing channel steels; the two sets of load-bearing channel steels are arranged in a parallel shape, and the top two sides of the two sets of load-bearing channel steels are connected by connecting plates respectively; a pad is provided at the top center of the two sets of load-bearing channel steels; and a gap is provided between the two sets of load-bearing channel steels, the load-bearing screw is connected to the connecting sleeve through the gap between the two sets of load-bearing channel steels via the pad, and the locking nut abuts against the pad; two sets of lifting components abut against the bottom two sides of the two sets of load-bearing channel steels respectively, and the top two sides of the two sets of load-bearing channel steels are connected by connecting plates, which enhances the integrity and stability of the structure.

[0028] Furthermore, the longitudinal section of the bearing channel steel is U-shaped, which gives it better bending and torsional strength; the openings of the two sets of bearing channel steels are respectively set outward; and each set of bearing channel steels is provided with several reinforcing ribs, which can increase the rigidity and strength of the channel steel and prevent it from deforming or breaking under stress.

[0029] Furthermore, a level is installed on the connecting plate on either side of the top of the two sets of supporting channel steels. The level can monitor the levelness of the connecting plate and the entire support assembly in real time.

[0030] Furthermore, the lifting assembly includes a lifting rod and a pad; one end of the lifting rod is fixed to the pad, and the other end abuts against the bottom of two sets of supporting channel steels; the pad abuts against the top of the pipe hanging device; the drive end of the lifting rod is connected to the control end of the controller. The lifting rod abuts against the bottom of the supporting channel steel, providing an additional support point for the entire structure. This helps to enhance the stability of the structure and prevent twisting or deformation under stress.

[0031] Furthermore, the controller includes a control module. The input of the control module is connected to a signal input module, and the output of the control module is connected to a signal output module. The input of the signal input module is connected to a stress detection plate. The output of the signal output module is connected to a processor and a drive module. The output of the drive module is connected to the drive end of the lifting rod. The stress detection plate can monitor the stress changes experienced by the pipe suspension device and support components in real time. When the stress exceeds a preset threshold, the stress detection plate sends a signal to the signal input module. Upon receiving the signal, the control module can quickly process it and trigger the corresponding response mechanism. Through the signal output module, the control module transmits instructions to the drive module, which then adjusts the height of the lifting rod to adapt to stress changes and ensure system stability.

This gives the load-bearing channel steel 6 better bending strength and load-bearing capacity. Simultaneously, each group of load-bearing channel steel 6 is equipped with several reinforcing ribs 7, enhancing its structural strength and stability.
