Dewar winding platform

Abstract

The invention discloses a Dewar winding platform comprising an operating room; a safety door for closing or opening the operating room is arranged on the operating room, a lifting mechanism for lifting or lowering a liquid nitrogen Dewar is arranged in the operating room, a support frame is arranged above the lifting mechanism, a clamping and rotating mechanism for clamping and rotating the liquidnitrogen Dewar is arranged above the lifting mechanism, a side-turning mechanism capable of driving the overall clamping and rotating mechanism to turn over in the rotating process of the clamping and rotating mechanism is arranged on the support frame, the clamping and rotating mechanism comprises a rotating motor arranged on the support frame, and a clamping chuck capable of clamping the liquidnitrogen Dewar is fixedly arranged at the shaft end of the rotating motor. A binding platform capable of adjusting binding speed according to Dewar width and performing comprehensive and automatic binding is provided, comprehensive binding is ensured, and the identical spaces between binding materials are guaranteed.

Description

technical field [0001] In particular, the present invention relates to Dewar dressing methods. Background technique [0002] Liquid helium Dewar is a container for liquid helium medium at a temperature of 4.5K. The liquid helium Dewar is an inner and outer interlayer container structure, with a high vacuum interlayer in the middle, and the inner container is wrapped with thermal insulation materials. The above structures are all to improve the thermal insulation performance of the Dewar. The wrapping quality of the material is the key to affect the thermal insulation performance of the liquid helium Dewar. Factors that affect the wrapping quality include the cleanliness of the wrapping material and the wrapping method. The material is wrapped in a spiral multi-layer, [0003] At present, the domestic liquid helium Dewar basically uses manual bandaging, which has the following defects: [0004] Unstable construction quality, uncontrollable degree of wrapping, errors in the ...

AI Technical Summary

Problems solved by technology

[0004] Unstable construction quality, uncontrollable degree of wrapping, errors in the calculation of wrapping layers, and uneven spacing between layers directly affect the thermal insulation performance of the Dewar;

[0005] The Dewar mezzanine space has strict cleanliness requirements, and there is a risk of artificial contamination in manual dressing;

[0006] Due to the need to strictly control the water absorption rate of the material, the wrapping process needs to strictly control the wrapping time, and the manual wrapping time is too long

Seriously affect the subsequent interlayer vacuum

have a significant impact on the performance of the device;

[0007] During the manual bandaging process, it is difficult to control the angle of the superimposed part, so that the bottom is superimposed

Contact with the bottom of the case causes a short circuit condition;

[0008] Workers bandaging has the disadvantage of low construction efficiency and cannot achieve mass production;

[0009] The quality control of wrapping has not been fundamentally guaranteed, and the efficiency is low. Manual wrapping is carried out in the form of Dewar circumferential surface, and the wrapping effect is not good; and it cannot provide a reasonable way of wrapping Dewar, which can guarantee the wrapping material after wrapping. At the same time, the end of the liquid helium Dewar axis is not easy to wrap, so the wrapping is not comprehensive; with the increase in the domestic demand for liquid helium, the demand for liquid helium Dewar will inevitably increase, and the liquid helium The stable mass production of Dewar becomes a reality, and a reasonable and comprehensive dressing platform must be provided
