Description
Technical field
The utility model relates to a kind of suspension pull bar of superconducting magnet low-temperature (low temperature) vessel.
Background technology
Superconducting magnet comprises room temperature part and is placed in the low temperature part of room temperature partial interior, and the suspension pull bar both connecting.Low temperature part provides pole low temperature environment, and as liquid helium region or liquid nitrogen temperature, room temperature part contacts with atmospheric environment, and the temperature difference is very large between the two, requires that hanging Tiebar structure leaks hot few.Simultaneously, superconducting magnet is under arms in the phase, different according to use scenes, can bear different load, the superconducting magnetic such as vehicle-mounted, carrier-borne or airborne is known from experience and is born larger shock and vibration, this shock resistance just requiring superconducting magnet to hang Tiebar structure to have had, shock resistance.Existing suspension pull bar, complex structure, manufacturing cost is high, and intensity is poor, and fail safe is not high.
Utility model content
The utility model aims to provide a kind of low-temperature (low temperature) vessel Tiebar structure, and leak hot little, intensity is high, simple for structure, low cost of manufacture, and fail safe is high.
The technical solution of the utility model is: a kind of low-temperature (low temperature) vessel Tiebar structure, comprises pull bar main body, metallic sheath, pre-load nut; Described metallic sheath has through hole, and external cylindrical surface has screw thread; Described metallic sheath is arranged on described pull bar body end, and metallic sheath and pull bar main body are interference fit; Described pre-load nut is arranged on metallic sheath.
Further, the mating surface of described pull bar main body and metallic sheath arranges interface glue, further bonding strength.
Further, there is one section of cone described pull bar main body termination, and cone, for reduce gradually from pull bar main body termination toward centre, improves the connection reliability of pull bar main body and metallic sheath further.
Further, the tapering of described cone is 1-5 degree.
Further, described pull bar main body termination is embedded with cone-shaped metal pin, forms bullet in pull bar body end, improves the connection reliability of pull bar main body and metallic sheath.
Further, the two-end structure of described pull bar main body is identical.
Further, an end face of described pre-load nut is sphere.
Further, described pull bar main body be low thermal conductivity without magnetic preparation of metals, as titanium alloy, stainless steel etc.
Further, described pull bar main body is the preparation of low thermal conductivity non-metallic material CFRP, GFRP, boron fibre or aramid fiber, or the combination preparation of above material.
The utility model is simple for structure, compact, and required installing space is little, low cost of manufacture, and intensity is high, and fail safe is high, leaks hot little, dependable performance.
