Owing to being subject to the restriction of volume and weight, the miniaturization of lifting mechanism, lightweight and high rigidity are the subject matter that designer considers all the time.In the prior art, the lifting mechanism majority that airborne photoelectric platform is used is to adopt upper, middle and lower three ply board formula structure to reach lifting object, then this upper, middle and lower three ply board formula structure is owing to adopting two independent parts, between the two, nothing is directly rigidly connected, this connection is unsteady, work is easily to produce and relatively move, and the lifting of lifter plate is caused to adverse effect, when serious, can cause lifter plate stuck.
Summary of the invention
The object of the invention is in order to solve lifting device structure that existing airborne photoelectric platform uses built on the sand, the problem that being rigidly connected property is poor, and the jacking system that provides a kind of airborne photoelectric platform to use.
For achieving the above object, technical scheme of the present invention is:
The jacking system that a kind of airborne photoelectric platform is used, this device comprises gear cluster, motor, matrix, lifter plate, four rhizoid thick sticks, four profile of tooth belt wheels and tooth form synchronous belt, described matrix is integral type structure, four rhizoid thick sticks are respectively through the lower end of matrix, lifter plate is passed by the upper end of matrix, profile of tooth belt wheel is fixed on the upper end of leading screw, tooth form synchronous belt is enclosed within on four profile of tooth belt wheels, when motor rotation, a rhizoid thick stick in gear set drive four rhizoid thick sticks rotates, by tooth form synchronous belt, drive four screw synchronous to rotate again, rotatablely moving of four rhizoid thick sticks is converted to the up-and-down movement of lifter plate.
Gear cluster of the present invention comprises driving gear and driven gear, and driving gear is arranged on motor, and motor is arranged on matrix, and described driven gear is connected with the rhizoid thick stick in four rhizoid thick sticks.
Device of the present invention also comprises four clutch shaft bearing assemblies and four the second bearing assemblies, and the two ends up and down of four described rhizoid thick sticks are connected with matrix with four the second bearing assemblies by four clutch shaft bearing assemblies.
Four rhizoid thick sticks of the present invention are connected with lifter plate by nut.
Beneficial effect of the present invention: and prior art compares, the present invention adopts the synchronous rotation of four rhizoid thick sticks, local stiffness is strengthened, prevented the distortion of lifter plate, made every rhizoid thick stick all play the effect of guide-localization, simultaneously, matrix adopting integrative-structure of the present invention, make lifting mechanism main body rigidity higher, structure is more succinct, firm.
