Description

Technical Field

[0001] This invention relates to the field of space environment testing technology, and in particular to a high-precision mechanism for moving large doors inside a vacuum container. Background Technology

[0002] Large test containers typically have pre-reserved passageways on their side walls to facilitate the entry and exit of samples and personnel. Because some tests require maintaining the container's complete aerodynamic shape, the openings in these passageways must be filled with door structures whose diameter matches the container's inner wall. These door structures are locked in place during use and withstand a certain amount of pneumatic pressure during operation. For personnel and goods to enter and exit, the door structure can be moved along the passageway. Therefore, a high-precision infeed / outfeed mechanism must be designed and installed inside the passageway to ensure the door structure's repeatability and positioning accuracy.

[0003] Currently, there are very few domestically available mechanisms for moving large components into and out of vacuum container doorways, and there are no similar examples of the moving mechanism for large door structures described in this invention. This invention addresses the specific testing requirements within vacuum containers and discloses a high-precision moving mechanism for large door structures within doorways. This mechanism comprises two parts: a mechanical system and a control system. It achieves high-precision automatic moving of large door structures, and this mechanism can also be extended to high-precision movement of large components in other similar working conditions.

The locking clamps are symmetrically arranged on both sides of the receiving frame.

[0013] Preferably, the operation of the infeed / outfeed mechanism includes the following steps:

[0038] The doorway moving guide rail mechanism 5 is provided with at least four, the sliding contact power supply mechanism 3 and at least four doorway moving guide rail mechanisms 5 are installed on the inner wall of the doorway 4, the doorway moving guide rail mechanism 5 is used for the door body structure 9 to move in the doorway diameter-depth direction, and the sliding contact power supply mechanism 3 provides driving power to the door body structure 9;

[0039] The power supply flange 6 is installed on the doorway 4, and the power supply cable of the sliding contact power supply mechanism 3 is connected through the power supply flange 6. The control cabinet 8 is installed on the side of the doorway 4 to control the entire process.

[0040] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the receiving structure 7 includes a sliding contact power supply docking mechanism 10, a moving guide rail 11, a receiving frame 12, and a locking clamp 13. The receiving structure 7 is used to receive the door structure 9, and the receiving structure 7 moves along the hanging guide rail 1 outside the door opening.

[0041] The sliding contact power supply docking mechanism 10 and the moving guide rail 11 are both installed on the receiving frame 12. Their installation positions are consistent with the height of the corresponding docking parts inside the door opening 4. The locking clamp 13 is symmetrically arranged on both sides of the receiving frame 12 and is used to lock the receiving structure 7 to the door opening 4.

[0042] The operation of the transfer-in / transfer-out mechanism includes the following steps:

[0043] S1, Unlock the inner door structure 9 of doorway 4;

[0044] S2. Start the external support structure 7 of the doorway 4 and move it laterally along the external hoisting guide rail 1 to the doorway 4;

[0045] S3, The supporting structure 7 is locked to the doorway 4 and extends out to connect with the track on the inner wall of the doorway 4 passageway;

[0046] S4. Start the drive motor of the gate structure 9, so that the gate structure 9 moves along the track to the receiving structure 7;

[0047] S5. Release the locking status of the supporting structure 7 and the doorway 4;

[0048] S6. Start the receiving structure 7, so that it moves laterally along the outside of the door opening to complete the door opening action;

[0049] S7. Start the receiving structure 7 and move it laterally along the hoisting guide rail 1 outside the doorway to the doorway 4;

[0050] S8. The supporting structure 7 locks with the doorway 4 and drives the door structure 9 to extend out of the docking track and dock with the track on the inner wall of the doorway passage.

Then, the receiving structure 7 is activated. The receiving structure 7 moves laterally along the external hoisting guide rail 1 of the door opening. After moving laterally to the position of the door opening 4, the moving guide rail 11 on the receiving structure 7 connects with the moving guide rail mechanism 5 inside the door opening, and the receiving structure 7 is locked by the locking clamp 13. After the receiving structure 7 is locked, the door structure 9 moves along the moving guide rail mechanism 5 inside the door opening to the moving guide rail 11. At this time, the moving guide rail 11 retracts and moves into the frame of the receiving structure 7. The receiving structure 7 drives the door structure 9 to move laterally to complete the door opening action.

[0055] When the door structure 9 is moved in, the receiving structure 7 is activated first. The receiving structure 7 moves laterally along the external hoisting guide rail 1 of the door opening. After moving to the position of the door opening 4, the locking clamp 13 locks the receiving structure 7. At this time, the moving guide rail 11 on the receiving structure 7 drives the door structure 9 to connect with the moving guide rail mechanism 5 inside the door opening. After the connection is completed, the door structure 9 moves along the moving guide rail mechanism 5 inside the door opening to the door frame 2. The receiving structure 7 moves laterally again along the external hoisting guide rail 1 of the door opening. After moving to the position of the door opening 4, the personnel enter the door opening 4 and lock the door to complete the closing action.
