The invention provides a device and method for anti-loosening tests of power transmission iron tower bolt wherein the device comprises a vibration device, a transmission device, an installation station, a temperature preserving device and a first testing device. The vibration device is used for generating vibrations. The transmission device is in connection with the vibration device to transmit vibrations. The installation station is in connection with the transmission device and is used for the installation of the power transmission iron tower bolt. The installation station is arranged inside the temperature preserving device and the temperature preserving device is further provided with a refrigeration device. The first testing device is arranged outside the temperature preserving device and is connected with the power transmission iron tower bolt to test the remaining pre-tightening force of the power transmission iron tower bolt. The device for anti-loosening tests of power transmission iron tower bolt of the invention provides a low temperature environment for conducting anti-loosening tests of power transmission iron tower bolt and enables the power transmission iron tower bolt to undergo anti-loosening tests at a low temperature. In addition, since the first testing device is arranged outside the temperature preserving device, the performances of the first testing device are immune to the impacts of the low temperature. Therefore, a more accurate testing result can be obtained.
Description
technical field [0001] The invention relates to the technical field of power transmission and transformation, in particular to a test device and method for anti-loosening bolts of power transmission towers. Background technique [0002] UHV technology is the basis for building the Global Energy Internet and realizing the coordinated development, allocation and utilization of energy resources, because only the UHV AC and DC power grids with high voltage levels, large transmission capacity, and long transmission distances can realize the interconnection between continents and continents in the world. Energy transmission between the internal energy base and the load center. [0003] my country is carrying out the construction of UHV power transmission projects. Compared with low- and middle-latitude regions, some UHV power transmission projects are located in high-latitude regions. In the construction of power transmission and transformation projects in this region, the first ...
