The utility model relates to the technical field of office tables, in particular to a supporting frame of an office table, which comprises foot stools, a cross beam assembly connected between the foot stools and a plurality of longitudinal beams connected on two sides of the cross beam assembly, the cross beam assembly comprises a cross beam and at least two groove covers, the cross beam forms a containing groove with a downward opening, and the containing groove is used for containing cables. The groove covers are used for covering the bottoms of the containing grooves and supporting the cables, the groove covers can slide in the transverse direction relative to the cross beam, after part or all of the groove covers slide, more than 95% of the containing grooves can be covered, after part or all of the groove covers slide, operation holes can be formed between the groove covers or between the groove covers and the foot stands, and the operation holes are used for communicating the outside with the containing grooves. According to the supporting frame of the office table, the problem that due to the fact that the length of the cross beam is large, cable wiring is difficult can be solved.

The invention relates to a fault diagnosis method for a circulating washing water pump based on wireless vibration waveform frequency spectrum monitoring, which solves the problems of difficulty in wiring and easiness in corrosion in a chemical field through LoRa wireless transmission and rigid installation of a sensor, and ensures the stability of signal acquisition. In addition, the method utilizes a frequency domain integral algorithm and fast Fourier transform to realize multi-dimensional spectrum analysis of vibration acceleration, speed and displacement, and overcomes the limitation of single index monitoring; meanwhile, in combination with characteristic frequency automatic labeling and fault judgment logic based on equipment parameters, accurate positioning and early warning of faults such as bearing abrasion and impeller abnormity are achieved, the operation and maintenance mode is converted into predictive maintenance from passive first-aid repair, and the risk of unplanned shutdown is effectively reduced.

The invention relates to the technical field of bolt fault detection, in particular to a bolt looseness detection method. The method comprises the following steps: acquiring a structure vibration video, and extracting synchronous vibration displacement signals of all selected pixel points from the video by using a phase method to construct an original signal sample library with labels; constructing a preprocessing module, combining the synchronization signals, and expanding training samples; constructing a recognition model, connecting a preprocessing module with a main classification network in series, carrying out supervised training by using an expanded data set, and carrying out combined optimization on parameters of a preprocessing convolution kernel and the classification network, so that the model can learn a mapping relation between a vibration signal and a bolt state; during actual detection, vibration videos of a structure in an unknown state are collected under the same excitation, a synchronizing signal is extracted, the synchronizing signal is input into the trained classification model for state prediction after being expanded by the trained preprocessing module, and the loosening position and degree of the bolt are comprehensively judged. According to the invention, non-contact and high-precision bolt looseness detection is realized.
