Background technology
Chinese patent ZL200620149557.2 discloses a kind of jack of airborne photoelectric platform, and this mechanism is mainly used in the aviation Reconnaissance system, is used for finishing the task that photoelectric platform exposes ventral and regains ventral.This mechanism comprises upper and lower mounting plate and the lifting disk between upper and lower mounting plate that is oppositely arranged, four lead screw shaft correspondences are assemblied in four bights of two plates, one dish successively, between upper and lower fixing plate and each lead screw shaft bearing is installed, is spiral between lifting disk and each lead screw shaft and cooperates; Four lead screw shaft connect by a Synchronous Belt Drives, and one of them lead screw shaft is the active lead screw shaft, and this is driven by gear pair by the drive motor that is installed on the upper mounted plate.During work, photoelectric platform is installed on the lifting disk, and drive motor drives initiatively lead screw shaft rotation, realizes the synchronous rotation of four lead screw shaft by synchronous cog belt, thereby drives the lifting disk up-and-down movement, realizes the folding and unfolding of photoelectric platform.Because this mechanism has adopted four lead screw shaft to drive the lifting disk up-and-down movement, and is all very high to the working accuracy and the matching requirements of this mechanism element, otherwise clamping stagnation even stuck phenomenon very easily occur, the frequency that occurs the clamping stagnation fault in the use also can be higher; On the other hand, it is also comparatively complicated on the structure of this mechanism self is formed.
The utility model content
At above-mentioned defective, the purpose of this utility model provide a kind of simple in structure, reduce the jacking system of processing and assembly precision requirement simultaneously.
For achieving the above object, the utility model adopts following technical scheme: a kind of jacking system, comprise two adapter plates that are oppositely arranged and place lifting disk between two adapter plates, two adapter plates and lifting disk are worn by four axles of correspondence setting and are connected together, one of them adapter plate is provided with drive motor, in four axles, two axles that are arranged on one group of diagonal angle are lead screw shaft, two axles that are arranged on another group diagonal angle are the axis of guide, be normal-running fit between lead screw shaft and two adapter plates, for worm drive cooperate, between the lifting disk and the axis of guide bearing fit between lead screw shaft and the lifting disk; Rotation is provided with imput shaft on the adapter plate of drive motor being provided with, described drive motor drives the imput shaft rotation by a transmission device, between imput shaft and two lead screw shaft, be equipped with synchronous drive mechanism, drive two lead screw shaft by two synchronous drive mechanisms and rotate synchronously.
Described drive motor drives the imput shaft rotation by Worm and Worm Gear Driving mechanism.
Described synchronous drive mechanism is a synchronous belt drive mechanism.
Be connected by the corresponding synchronous band between the corresponding driven synchronous pulley of installing on two active synchronization belt wheels that described synchronous belt drive mechanism comprises that crankshaft drive on the imput shaft installs and two lead screw shaft, two active synchronization belt wheels and cooresponding driven synchronous pulley.
Described synchronous drive mechanism is the chain type synchronous drive mechanism.
The corresponding driven sprocket of installing on two drive sprockets that described chain type synchronous drive mechanism comprises that crankshaft drive on the imput shaft installs and two lead screw shaft, be connected by corresponding messenger chain between two drive sprockets and the cooresponding driven sprocket, two chain-drive transmitting ratios are 1.
The utility model adopts the worm drive lifting mechanism of two lead screw shaft and two axis of guides, add that employing drives two cover synchronous drive mechanisms simultaneously by same power and drives cooresponding lead screw shaft respectively and do synchronous rotation, compare with the lifting mechanism of four lead screw shaft, this device is not only simple in structure, compact, and the accuracy requirement that can reduce processing and assemble, simultaneously can also improve its net synchronization capability, realize the lifting that lifting disk can be nimbly and freely, reduce the frequency that clamping stagnation occurs.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Jacking system shown in Figure 1, comprise two adapter plates 2,5 that are oppositely arranged and place lifting disk 4 between two adapter plates, two adapter plates and lifting disk 4 are worn by four axles of correspondence setting and are connected together, one of them adapter plate 2 is provided with drive motor 8, in four axles, two axles that are arranged on one group of diagonal angle are lead screw shaft 3,9, two axles that are arranged on another group diagonal angle are the axis of guide, between lead screw shaft 3,9 and two adapter plates 2,5 is normal-running fit, for worm drive cooperate, between the lifting disk 4 and the axis of guide bearing fit between lead screw shaft and the lifting disk 4; On the adapter plate 2 that drive motor is set, rotate and be provided with imput shaft, described drive motor 8 drives the imput shaft rotation by Worm and Worm Gear Driving mechanism 7, be equipped with synchronous drive mechanism between imput shaft and two lead screw shaft, this two synchronous drive mechanism drives two lead screw shaft 3,9 and rotates synchronously.
Synchronous drive mechanism in the present embodiment is the chain type synchronous drive mechanism, the corresponding driven sprocket of installing 1,11 on two drive sprockets that this mechanism comprises that crankshaft drive on the imput shaft installs and two lead screw shaft, be connected by corresponding messenger chain 10 between two drive sprockets and the cooresponding driven sprocket 1,11, the transmitting ratio of this two chain drive is 1.As required, can also the degree of tension that two chain tensioning mechanism (not shown)s are used for adjusting corresponding messenger chain be installed on adapter plate 2, to strengthen the reliability of whole lifting mechanism transmission.
During work, drive motor 8 drives imput shaft by Worm and Worm Gear Driving mechanism and rotates, imput shaft drives the two drive sprockets rotation synchronously thereupon on it again, rotary power further drives two lead screw shaft 3,9 by corresponding messenger chain and driven sprocket and does synchronously and rotatablely move, thereby drive lifting disk 4 and do straight-line motion along the axis of guide, the straight-line direction of lifting disk is changed by the rotation direction of drive motor.
During concrete enforcement, above-mentioned synchronous drive mechanism also can adopt synchronous belt drive mechanism, at this moment, only need get final product with corresponding sprocket wheel and messenger chain in synchronous pulley and the said mechanism of band replacement synchronously.
