A connection structure between a heat sink container and a lifting platform

Abstract

The invention relates to the technical field of space environment simulation test equipment, and discloses a connecting structure of a heat sink container and an ascending and descending platform. The connecting structure comprises the heat sink container and the ascending and descending platform, wherein the outer bottom of the heat sink container is fixed with a base through support feet, the lower side of the ascending and descending platform is connected with a plurality of ascending and descending upright posts, the bottom of the heat sink container is provided with a plurality of connecting holes, a support sleeve is fixedly arranged in each connecting hole, the lower end of each ascending and descending upright post is vertically connected with the base through passing through the corresponding support sleeve, the ascending and descending upright posts are in clearance fit with the support sleeves, annular notches are formed in the inner wall of two ends of each support sleeve, a guide sealing sleeve is arranged in each annular notch, three annular grooves are formed in positions, positioned among the guide sealing sleeves, on the inner wall of each support sleeve, and a sealing ring is arranged in each annular groove. Therefore the connecting structure has the beneficial effects that the load of the heat sink container is not increased, and the sealing performance at a connecting part is good.

[0002] The heat sink container is a common space simulation test equipment. The heat sink is installed on the inner wall of the heat sink container to ensure the low temperature environment in the heat sink container. During the test, the air in the heat sink container is pumped out by a vacuum machine to create a vacuum environment. , so as to simulate the low temperature and vacuum environment in space. In order to meet various experimental requirements, a lifting platform will be installed in the heat sink container. The load on the sinking container increases. The general heat sinking container is very large in size, with a diameter ranging from a few meters to more than ten meters. In order to ensure its own strength, the heat sinking container has a thicker wall and a heavier self-weight. However, the lifting platform is also very heavy. , the lifting platform of a large heat sink weighs tens of tons, and the load of the lifting platform directly acts on the heat sink container, which will obviously seriously affect the strength and service life of the heat sink container itself; the second heat sink container itself Deformation will occur, which will affect the flatness and verticality of the lifting platform. Third, the lifting platform is driven by a motor, and the oil inside the motor will float out and pollute the vacuum environment in a vacuum state, which cannot meet some experimental requirements.
