Automatic comprehensive detection flaw detection equipment for railway line
ActiveCN119611441Aimprove performanceEfficient and accurate detectionRailway inspection trolleysRailway cleaningStructural engineeringMechanical engineering
The invention relates to the technical field of railway line flaw detection, in particular to railway line automatic comprehensive flaw detection equipment which comprises two steel rails and a flaw detection car and further comprises a C-shaped mounting plate, a buffer assembly, a waist detection mechanism and a bottom detection mechanism. A first fixing rod is transversely arranged in the C-shaped mounting plate, fixing sleeves are slidably connected to the two ends of the first fixing rod correspondingly, and balance assemblies are arranged at the ends, away from each other, of the two fixing sleeves correspondingly. The device has the advantages that different detection assemblies are arranged for different detection areas, so that steel rail detection of different parts is more efficient and accurate, it is ensured that different types of defects can be detected, the detection period is shortened, the balance assembly and the buffer assembly cooperate with each other to enable the head detection assembly to keep a dynamic balance state, and the detection efficiency is improved. The probe is effectively protected from vibration damage, and the adaptability of the probe to the change of the steel rail and the detection stability of the probe are improved.

A self-adjusting landing structure for unmanned aerial vehicles
This utility model relates to the field of unmanned aerial vehicle (UAV) technology and discloses a self-adjusting landing structure for UAVs. The structure includes a UAV body, a mounting base fixedly mounted on the UAV body, a mounting plate at the bottom of the mounting base, grooves and slots on the outer wall of the mounting plate, a locking disc on the outer wall of the mounting plate, and a locking rod on the outer wall of the mounting plate. Through the linkage design of the buffer airbag and the air outlet component, adaptive adjustment to different ground hardness is achieved. When the UAV lands, the internal air pressure of the buffer airbag increases after being compressed, and the pressure pushes the sealing plate to slide open the air hole for pressure relief. The greater the impact force, the larger the air hole opening, the faster the pressure relief speed, and the stronger the buffering effect. Whether it is the high impact of hard cement ground or the continuous compression of soft sand, this structure can dynamically adjust the buffering force to avoid excessive vibration or sinking of the fuselage, effectively protecting the precision equipment inside the UAV and significantly improving landing safety.
