Description
Technical field
The utility model relates to a kind of unsteady isolation mounting of vacuum reservoir of experimental facilities, belongs to mechanical structure field.
Background technology
Carry out in the equipment of space environment simulation test at present, adopt between the opening and closing device at vacuum reservoir gate and gate and be rigidly connected, and after vacuum reservoir was installed on the vibration-isolating platform that floats, opening and closing device can import exterior vibration into vacuum reservoir, and vibration will influence a jar build-in test effect.
The utility model content
The utility model purpose provides a kind of vacuum reservoir isolation mounting that floats, and produces the problem of vibration effect test effect in the time of can solving the vacuum reservoir gate and close.A kind of vacuum reservoir isolation mounting that floats, comprise " door " cabinet frame, overhead traveling crane, the unloading isolation mounting, vacuum reservoir, the vacuum reservoir gate, vibration-isolating platform and ground float, the unloading isolation mounting is by downside pin, connector, post carried by overhead traveling crane and last pin is formed, wherein " door " cabinet frame is fixedly mounted on the ground, overhead traveling crane be installed in " door " cabinet frame top and can about walking, the upper end of unloading isolation mounting is carried post by last pin with the overhead traveling crane of overhead traveling crane bottom and is linked to each other, captive joint with the vacuum reservoir gate by downside pin in the lower end of unloading isolation mounting, pin joint is on connector about last pin and the downside pin, the pin-and-hole of last pin is an ellipse, and oval path is greater than the diameter of last pin; Vacuum reservoir is fixedly mounted on the vibration-isolating platform that floats, and unsteady vibration-isolating platform is installed on the ground.
Mode of operation: under sky vehicle motor effect, overhead traveling crane is carried the post upward movement, and pin is subjected to upper pulling force, by the transmission of connector, downside pin is upward movement also, because downside pin is connected with the vacuum reservoir gate, so the vacuum reservoir gate is mentioned by overhead traveling crane, to the left or the right side remove.When closing the vacuum reservoir gate, overhead traveling crane hangs the vacuum reservoir gate and shifts to vacuum reservoir, after treating that vacuum reservoir gate and vacuum reservoir are fixing, overhead traveling crane is carried post and is moved down, because the pin-and-hole of last pin is an ellipticity, the gap appears in the pin bottom on this moment, causes pin not to be subjected to upper pulling force, overhead traveling crane and the disengaging of last pin are rigidly connected, i.e. overhead traveling crane and vacuum reservoir gate disengaging is rigidly connected; The vibration of being passed to cart by ground can not imported vacuum reservoir gate and vacuum reservoir into.
Beneficial effect: the utility model is used in space flight vacuum experiment equipment, the vacuum processing apparatus, and the vacuum reservoir gate can not import external vibration into vacuum system when opening with closure, has effectively guaranteed the accuracy of test.

Wherein: 1-" door " cabinet frame, 2-overhead traveling crane, 3-unloading isolation mounting 4-vacuum reservoir gate, the unsteady vibration-isolating platform of 5-, 6-ground, 7-downside pin, 8-connector, 9-overhead traveling crane are carried post, the last pin of 10-.
The specific embodiment
As shown in Figure 1, a kind of vacuum reservoir isolation mounting that floats, comprise " door " cabinet frame 1, overhead traveling crane 2, unloading isolation mounting 3, vacuum reservoir, vacuum reservoir gate 4, float vibration-isolating platform 5 and ground 6, unloading isolation mounting 3 is carried post 9 by downside pin 7, connector 8, overhead traveling crane and is gone up pin 10 and form; Wherein " door " cabinet frame 1 is fixedly mounted on the ground 6, overhead traveling crane 2 be installed in " door " cabinet frame 1 top and can about the walking, the upper end of unloading isolation mounting 3 is carried post 9 by last pin 10 with the overhead traveling crane of overhead traveling crane 2 bottoms and is linked to each other, captive joint with vacuum reservoir gate 4 by downside pin 7 in the lower end of unloading isolation mounting 3, last pin 10 and downside pin about in the of 7 pin joint on connector 8, the pin-and-hole of last pin 10 is an ellipse, and oval path is greater than the diameter of last pin 10; Vacuum reservoir is fixedly mounted on the vibration-isolating platform 5 that floats, and the vibration-isolating platform 5 that floats is installed on the ground 6.
Under sky vehicle motor effect, overhead traveling crane is carried post 9 upward movements, and pin 10 is subjected to upper pulling force, by the transmission of connector 8, downside pin 7 is upward movement also, because downside pin 7 is connected with vacuum reservoir gate 4, so vacuum reservoir gate 4 is mentioned by overhead traveling crane 2, to the left or the right side remove.When closing vacuum reservoir gate 4, overhead traveling crane 2 hangs vacuum reservoir gate 4 and shifts to vacuum reservoir, after treating that vacuum reservoir gate 4 and vacuum reservoir are fixing, overhead traveling crane is carried post 9 and is moved down, because the pin-and-hole of last pin 10 is an ellipticity, the gap appears in pin 10 bottoms on this moment, causes pin 10 not to be subjected to upper pulling force, overhead traveling crane 2 is rigidly connected with last pin 10 disengagings, and promptly overhead traveling crane 2 is rigidly connected with 4 disengagings of vacuum reservoir gate; The vibration of being passed to overhead traveling crane 2 by ground 6 can not imported vacuum reservoir gate 4 and vacuum reservoir into.
