Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is done to further detailed description:
As shown in Figure 1, 2, 3, the present invention includes base 1, turbine and worm mechanism 2, two-way stop clutchDevice 16, turbine wheel shaft 3, nut 4, load sleeve 5, fairlead 6, limit switch 7, oblique cone bearing 8,Bearing cutting ferrule 9, end cap 10, LOAD CELLS 11, ball head structure 12, bellows 13 and displacement sensingDevices 15 etc., turbine and worm mechanism 2 is arranged on base 1 by a pair of oblique cone bearing 8, oblique cone bearing 8By bearing cutting ferrule 9 axial restraints, the upper design of turbine wheel shaft 3 becomes ball screw assembly,, and stepper motor 14 is logicalCross two-way stop clutch 16 and drive worm-and-wheel gear 2 speed reducing rotations, the effect of two-way stop clutchBe to prevent the rotation of worm gear pair under non-motor drives, nut 4 is fixedly connected with load sleeve 5, turbineAxle 3 is connected with nut 4 by ball screw assembly,, and nut 4 is converted into rotatablely moving of ball screw assembly,Axially-movable, the load sleeve 5 being fixed on nut 4 moves up and down with nut 4, and load sleeve 5 is with solidThe fairlead fixing on base 1 connects by bonding, and for preventing the rotation of nut 4, it can be spiral shell simultaneouslyFemale 4 motion guide, the bottom of load sleeve 5 is provided with limit switch 7, by being connected on nut 4Lance clash into limit switch 7 and carry out the spacing up and down of supporting leg lifting, load sleeve 5 end is installed aboveLid 10 is for LOAD CELLS 11 is installed, and end cap 10 is installed ball head structure 12 above, at end cap 10 and ballLOAD CELLS 11 is installed between header structure 12, and the top of ball head structure 12 is platform, at the bottom of itself and horizontal standThe fixing ball bowl of portion matches, and has relatively rotating of two orthogonal directions between bulb and ball bowl in leveling process,Thereby drive the motion of horizontal stand, reach the object of leveling.
The connected mode of turbine and worm structure and motor is: stepper motor 14 is by two-way stop clutch 16Drive worm screw revolution, under stepper motor 14 powering-off states, two-way stop clutch 16 limits worm shaft and revolvesTurn, prevent that support leg mechanism from producing motion under gravity and load effect, ensure the security of platform legs mechanism.
As shown in Figure 3, the LOAD CELLS 11 that supporting leg ball head structure 12 is embedded with, props up in order to surveillance satelliteThe distribution situation of the load that frame transmission is got off in platform legs, avoids sending out of the unsettled this unsafe condition of fulcrumRaw, load sleeve 5 outside wall surface are provided with displacement transducer 15, the top nut 4 of direct-detection worm-wheel shaft and leading screwBetween relative position, more accurate to the measure of the change of leg length, coordinate the high accuracy of installing on satelliteLevel meter is combined use and is realized levelness fine adjustment. In order to ensure levelling gear in normal temperature atmospheric environment,Platform legs mechanism adopts bellows 13 to seal, and displacement transducer 15 and lead limit switch 7 are all pacifiedThe bellows 13 that is contained in the strong point seals in normal temperature environment, between LOAD CELLS 11 and levelling gear, passes throughTemperature control is unified in heat conduction, and displacement transducer 15 and limit switch 7 holding wires are by being arranged on baseSealing to through the wall plug be connected to sylphon seal cavity outside. At the outside coated multilayer insulation material of supporting leg,Heat insulation with satellite L support junction thickening glass epoxy, stick on heating plate in supporting leg outside, several measuresEmploying ensured that supporting leg inside remains on normal room temperature environment, make platform legs can normally be operated in vacuumUnder low temperature environment.
