[0031] As is generally known, a load sensor (often also called a "load transformer") is an electronic device that converts tension and compressive force into corresponding electrical signals. The following is a detailed introduction to load sensors: The working principle of a load sensor is based on strain measurement. When an object is subjected to a force, its shape and size undergo minute changes; this deformation is called strain. Strain is directly proportional to the magnitude and direction of the force applied to the object. Load sensors measure weight or load-bearing capacity by measuring the strain caused by the force applied to an object. Specifically, a load sensor typically consists of a metallic elastic body (such as a spring or winding). When subjected to a force, the elastic body deforms, causing changes in physical quantities such as resistance, capacitance, or inductance. This change can be measured by electronic components within the sensor and converted into an electrical signal output proportional to the magnitude of the applied force.
[0032] refer to Figure 1 and Figure 2 The anti-eccentric load pipeline load monitoring device of this utility model includes a ball cone washer 1, a load sensor 2, a fixed channel steel 3, a bearing rod 4, an anti-eccentric load fixing sleeve 5, an anti-eccentric load fixing plate 6, and a locking nut 7.
[0033] The load-bearing member 4 passes through the locking nut 7, the ball-cone washer 1, the anti-eccentric load fixing plate 6, the load sensor 2, the anti-eccentric load fixing sleeve 5, and the fixing channel steel 3 from top to bottom. The lower end of the load sensor 2 is inserted into the anti-eccentric load fixing sleeve 5, and the upper end of the load sensor 2 is in contact with the bottom of the anti-eccentric load fixing plate 6.
[0034] It should be noted that the ball-cone washer 1 is located on top of the anti-eccentric load fixing plate 6. When the bearing member 4 experiences unavoidable eccentric loading, the sliding assembly of the ball-cone washer 1 undergoes adaptive structural deformation, ensuring that the force acting on the anti-eccentric load fixing plate 6 remains in its initial direction regardless of the eccentric load on the bearing member 4. This guarantees that the load sensor 2 is in a standard testing environment, ensuring the reliability and stability of the experimental data. The load sensor 2, the anti-eccentric load fixing sleeve 5, and the bearing member 4 are dimensionally matched to ensure the accuracy of the monitoring data while fixing the load sensor 2. The inner diameter D1 of the load sensor 2 is the same as the inner diameter d of the lower end of the anti-eccentric load fixing sleeve 5 and the diameter of the bearing member 4. The outer diameter D3 of the load sensor 2 is the same as the inner diameter D of the sleeve portion in the anti-eccentric load fixing sleeve 5. The detection section of the bearing member 4 is placed inside the load sensor 2, which is fixed inside the anti-eccentric load fixing sleeve 5. The height of the load sensor 2 is higher than that of the anti-eccentric load fixing sleeve 5. The anti-eccentric load fixing sleeve 5 and the anti-eccentric load fixing plate 6 act directly on the load sensor 2 and are not affected by the eccentric load of the bearing member 4. The bearing member 4 is fixed to the ball-cone washer 1 by the locking nut 7 to prevent the anti-eccentric load fixing plate 6 from loosening due to vibration or other external forces during service, ensuring the stability of the equipment and the accuracy of the measurement data. The anti-eccentric load fixing sleeve 5 is welded to the fixing channel steel 3, which can be modified according to the bearing structure under actual working conditions.
[0035] It should be noted that this utility model greatly improves the accuracy and stability of pipeline load monitoring, especially for pipeline load monitoring with off-center loads. The simple structure improves the stability of the system, reduces the impact of external interference on the data, and ensures the stability and durability of the equipment during long-term service. This design adapts to various working conditions, improves the efficiency and accuracy of pipeline load monitoring, and provides a reliable guarantee for pipeline safety management and equipment maintenance.
