Description

Cement electric pole stress testing device Technical Field The utility model relates to the technical field of testing devices, in particular to a cement electric pole stress testing device. Background The cement electric pole stress testing device is key equipment for evaluating the structural safety of the cement electric pole in the field of electric power engineering, and is mainly used for detecting the stress distribution and bearing capacity of the electric pole under the actual working condition. The method has the core functions of judging whether the electric pole has structural defects or performance hidden trouble by simulating loads such as axial pressure, bending moment, torque and the like born by the electric pole during service and combining stress data acquired by a sensor. The device generally comprises a loading system, a stress measuring system, a displacement monitoring module and a control unit, wherein the loading system applies load to the electric pole in a hydraulic or mechanical mode, the stress measuring system captures internal stress changes of the electric pole by means of sensors such as strain gauges and stress meters, and the displacement monitoring module synchronously records deformation data of the electric pole. In the production link, the testing device can carry out quality spot check on the cement electric pole to ensure that the product meets the design standard, and in the operation and maintenance stage, the stress abnormality caused by aging, corrosion or external damage can be timely found through the periodic detection on the service electric pole, so that the data support is provided for the safe operation of the electric power infrastructure. Currently mainstream cement pole stress testing devices generally adopt a loading mode of clamping one end and pulling one end, namely one end of a pole is fixed through a clamping part, and a pulling part is utilized to apply load to the other end. However, the structural design has the obvious defect that the clamped end of the electric pole is in a suspended state in the test process, and the sag deformation of the detection end can be caused by the gravity of the electric pole due to the lack of an additional supporting structure. The additional stress caused by gravity not only disturbs the accuracy of the test data, but also can cause the stress distribution to deviate from the actual working condition, so that the deviation of the detection result occurs.
