The utility model relates to a technical field of hanger, concretely is a socket type reinforced concrete pipe hanger, including gallows, the lifting lug that sets in the middle part of gallows upside, the load bearing chain that sets in the both ends of gallows downside respectively, and the C type lifting hook that is connected with two load bearing chain lower end respectively and symmetrical layout, still including the unhooking tensioning mechanism that sets in the inside upside of two C type lifting hooks, the telescopic drive mechanism that sets in the middle part of gallows downside, and the inside support clamping mechanism that sets in the downside of two C type lifting hooks respectively and symmetrical layout, the output of telescopic drive mechanism is connected with the upside middle part transmission of unhooking tensioning mechanism, this hanger can form reliable restraint from inside and outside two sides through the cooperation of inside support clamping mechanism, unhooking tensioning mechanism and telescopic drive mechanism, eliminates the hidden danger of pipe body slip in the hoisting process, improves the operation safety.

The application provides a high altitude balloon launching method and a composite high altitude balloon. The high altitude balloon launching method comprises the following steps: putting the high altitude balloon into a windproof air bag, and connecting the high altitude balloon, a cable and a gondola in sequence; arranging winch pull ropes on the periphery of the windproof air bag, and arranging cutters on the winch pull ropes respectively; filling air into the windproof air bag and filling helium into the high altitude balloon, and controlling the pressure difference between the windproof air bag and the high altitude balloon within a preset pressure difference range after the filling is completed; releasing the windproof air bag and synchronously releasing the winch pull ropes; cutting the winch pull ropes by using the cutters when the distance between the gondola and the ground is greater than a first safety height; and detaching the windproof air bag to make the windproof air bag separate from the high altitude balloon when the distance between the gondola and the ground is greater than a second safety height. The high altitude balloon launching method and the composite high altitude balloon provided by the application aim to solve the problem that the wind resistance of the high altitude balloon is weak and the high altitude balloon is easy to be damaged in the launching process in the prior art.

The application discloses a SAM2 small sample segmentation method based on semantic-visual double memory fusion, constructs semantic query memory, visual query memory and query related support visual memory, fuses the semantic query memory and the visual query memory through a memory refinement module guided by the query related support visual memory, and combines SAM2 dense matching and decoding module end-to-end training. The method solves the single memory and foreground-background confusion problems of the existing method, enhances target semantic consistency and fine-grained modeling capability, significantly improves segmentation precision and generalization capability in a complex scene, and is suitable for medical image analysis, automatic driving and the like.
