The utility model provides an integral double-airbag electric drive trailer axle, which relates to the technical field of trailer chassis and comprises a first trailer axle assembly, a second trailer axle assembly and a third trailer axle assembly. The first trailer axle assembly comprises a first trailer axle body; the first trailer axle body comprises a first body middle section, a front guide arm, a front support boss, a rear guide arm, an air bag installation boss, a disc brake flange, a half shaft sleeve, a damping rod boss, an axle package and an oil drainage hole boss. Compared with an existing electrically-driven trailer axle housing, the integral type double-airbag electrically-driven trailer axle has the advantages that high integration of the trailer axle body is achieved, use of connecting pieces is reduced, the problem that the shape and the space of the corbel are seriously limited is solved, the structure of the corbel is simplified, the quality cost of the axle housing unit is reduced, the assembly process is simplified, and the production efficiency is improved. Failure risk points of current traditional axle housing bolt connection are eliminated, and the overall stability of the electrically-driven trailer axle housing is improved.

The present application discloses a method for identifying small parts faults in power transmission lines, including: obtaining a field image containing a target small part category on the power transmission line, performing multi-scale processing on the field image to obtain a multi-scale image feature map and a multi-scale sub-region feature map; performing enhancement processing on the multi-scale sub-region feature map, performing feature fusion on the processed multi-scale sub-region feature map and the multi-scale image feature map to obtain a multi-scale target region enhancement feature map, and then processing it to obtain a feature-optimized multi-scale fusion feature map; using the created image data set as a training set to train the constructed initial model, and using the trained model as a small part fault feature analysis model; analyzing the feature-optimized multi-scale fusion feature map based on the small part fault feature analysis model to obtain small part fault identification information. The method can realize accurate identification of small part faults in power transmission lines and meet the inspection needs under different terrains and landforms.
