The invention relates to the technical field of anti-explosion armored vehicles, particularly to a military vehicle flexible antimine ground plate. The military vehicle flexible antimine ground platecomprises an upper plate, a bottom limiting connecting plate and a support, wherein the upper plate is a hollow-out plate, a plurality of slots are formed around the three sides of the upper plate andsequentially arranged into bar-shaped slots, a plurality of rows of bar-shaped slots are arranged side by side to form a slot zone, which separates the outer circle and the inner circle of the upperplate, and during explosion, the slot zone is deformed to cut off force transferred by the outer circle of the upper plate as well as the part in contact with the feet of the inner circle of the upperplate; the bottom limiting connecting plate is in a frame shape composed of two vertical plates and a horizontal plate; the support is in an L-shaped structure and connects the upper plate and the bottom limiting connecting frame; between the upper plate and the bottom limiting connecting frame is hollow. By means of the support connected with the upper plate and the bottom limiting connecting frame, the military vehicle flexible antimine ground plate can achieve certain deformation resistance and support properties, increase the overall static rigidity and ensure sufficient strength during daily application.

The invention discloses a splicing type vibration-damping lead wooden frame used in an oil-immersed transformer, which comprises cross beams fixed on an upper transformer clamping plate and a lower transformer clamping plate and a longitudinal beam used for fixing the lead, wherein the two ends of the longitudinal beam are respectively connected with the two cross beams through tenon and an mortise structures. A certain gap is arranged between the tenon and the mortise in the mortise and mortise structure, and the gap is filled with an elastic sealing glue after curing. Through the non-rigid connection of the tenon and mortise structure, the vibration of the transformer can be buffered, and the effect of damping and noise reduction is realized on the basis of meeting the lead supporting function.

The invention relates to the technical field of coating equipment, in particular to automobile coating equipment in the field of intelligent manufacturing, the automobile coating equipment comprises a conveying mechanism and a coating assembly, and the conveying mechanism is further provided with a first brush head assembly, a lifting assembly, a cleaning assembly and a drying assembly. The cleaning assembly cleans the workpiece polished by the friction mechanism, so that dust and impurities cannot remain on the surface of the workpiece, the subsequent coating effect is improved, then a coating agent is sprayed to the workpiece through the coating assembly, and the lifting assembly drives the first brush head assembly to be matched with the size of the workpiece; the first brush head assembly is driven to uniformly smear the surface of the workpiece, so that a coating agent is uniformly attached to the workpiece, marks left on the surface of vehicle paint due to non-uniform smearing are reduced, and the coating effect is further improved; and the workpieces are dried through the drying assembly, so that the whole coating process is completed.
