Large vacuum container door operating mechanism

Abstract

The invention discloses a large vacuum container gate operation mechanism. The large vacuum container gate operation mechanism comprises a walking rail, two sets of driving walking hanging devices and a gate clamping mechanism, wherein the two sets of driving walking hanging devices both include driving wheels for rolling and walking in walking rails, clutches, motors, height adjusting mechanisms and gravity center adjusting mechanisms; the motors drive the driving wheels to roll along the walking rails through the clutches so as to drive a vacuum container gate to walk along the walking rails; the height adjusting mechanisms realize swing of the gate by a certain angle in the vertical direction; and height adjusting screw rods adjust the gate hanging height to realize up-down adjustment of the position of the gate, so that the gate hanging position is overlapped with the gravity center of the gate to realize perpendicularity between a flange sealing surface and the horizontal plane after gate hanging. The large vacuum container gate operation mechanism has the characteristics of compact layout and less factory building occupied space, is simple in structure, convenient to adjust, stable in operation and high in reliability, and can satisfy high-performance requirements of opening and closing of a large spacecraft space environment simulator gate.

Description

technical field [0001] The invention belongs to the field of design and manufacture of a large-scale spacecraft space environment simulation equipment, that is, a vacuum vessel. Specifically, the invention relates to a gate operating mechanism for translationally opening and closing a gate of a large-scale vacuum vessel. Background technique [0002] In large-scale spacecraft space environment simulation equipment, in order to meet the needs of spacecraft entering and exiting the vacuum container of space environment simulation equipment, there is usually a large door on the vacuum container. Usually, the gates of these large vacuum containers have the characteristics of large size and heavy weight; for example, a circular gate with a diameter of about 10 meters, a thickness of about 3 meters, and a weight of 30 tons; a square gate with a height and width of about 5 meters , the thickness can reach 1 meter, and the weight can reach 20 tons. At the same time, the door needs ...

AI Technical Summary

Problems solved by technology

The opening of the rotary door requires the door to rotate around the shaft, which takes up a lot of space; the translation and opening perpendicular to the flange sealing surface also takes up a lot of space; when the door is opened parallel to the direction of the flange sealing surface, and the ground running trolley method is used, Running trolleys on the ground requires the construction of special trolley tracks, which occupy a relatively large area
