Abstract
The invention relates to a turnover satellite borne antenna locking releasing device which consists of a switchover piece, a rotor shaft, a torsional spring, a pressure plate, a locking lever, a limitcover, a spring cover, a spring, a locknut, a ball pad, a support and a cutter. The invention effectively transforms the impact force applied to the locking lever in cutting to the release power through the limit cover on the pressure plate, and the release power and the torsional force of the torsional spring act together, thereby increasing the separating speed between the pressure plate and the support and increasing the separating reliability. The exposed part of the locking lever under the pressure plate is shorter after the locking lever is cut, the turnover angle of the pressure plateis big, and the pressure plate is kept to be fixed after being in place under the moment action of the torsional spring so as to enable the pressure plate to keep a longer distance from the support, thereby ensuring the rotation reliability of the antenna; meanwhile, the invention has simple structure, therefore facilitating production and manufacture.
Description
Technical field
The present invention relates to a kind of turnover space-borne antenna locking releasing device, relate in particular to a kind of locking releasing device of spaceborne continuous 360 degree rotable antennas, be mainly used in satellite antenna.
Background technology
Continuous 360 degree rotable antennas mainly are made up of reflector and high frequency case, and the high frequency case is connected with rotating mechanism as the supporting construction of reflector, and rotating mechanism drives the high frequency case and then driven antenna is done continuous 360 degree scannings.
At present, locking of using on the satellite antenna and releasing device, need two parts of locking can in short distance, make rectilinear motion up and down, adopt traditional locking to discharge aft antenna and move upward, finally finish the release separating action, after traditional locking and the releasing device release together with pressing plate with the releasing device release, rely on antenna to move upward to drive pressing plate and together move upward, make pressing plate and bearing contact-making surface separately, and be in more remote, no two-way process.Because the undirected motor function that goes up of the antenna of continuous 360 ° of rotations, after the separation not only pressing plate can not effectively separate with the bearing contact-making surface and also cut check lock lever can not effectively extract bearing hole bottom, so antenna can't freely rotate, so adopting conventional apparatus to discharge rear fender can not effectively separate with bearing, conventional apparatus antenna can't be rotated freely, so can not be applied to the locking and the release of continuous 360 ° of rotable antennas.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, a kind of turnover space-borne antenna locking releasing device is provided, the present invention is simple in structure, and pressing plate is effectively separated with bearing, has guaranteed antenna rotation reliability.
Technical scheme of the present invention is: a kind of turnover space-borne antenna locking releasing device, by adaptor, rotating shaft, torsion spring, pressing plate, check lock lever, position-limiting cover, spring shield, spring, locking nut, the ball pad, bearing and cutter are formed, adaptor be connected with the rotating part of antenna, bearing is connected with the standing part of antenna, adaptor by rotating shaft and pressing plate shaft to being connected, torsion spring is installed in the rotating shaft, and apply torsion by adaptor and pressing plate, pressing plate is connected by check lock lever with bearing, one end and the bearing of check lock lever are connected, the other end is successively by the ball pad, locking nut, spring is connected with pressing plate locking with spring shield, priming system is housed on the bearing to be used to cut off screw rod pressing plate is separated with bearing, position-limiting cover is installed on pressing plate is used to transmit the impulsive force that produces when check lock lever cuts off, spring is maintained fixed after screw motion is put in place.
Priming system is cutter or blasting bolt or distinguish nut.
The present invention's beneficial effect compared with prior art is: impulsive force suffered when the present invention cuts check lock lever by the position-limiting cover on the pressing plate effectively is converted into release power, this discharges the torsion acting in conjunction of power and torsion spring, thereby increased the speed that pressing plate separates with bearing, improved the reliability of separating; Check lock lever of the present invention exposed parts under pressing plate after being cut is shorter, and the pressing plate flip angle is big, under the moment loading of torsion spring pressing plate is maintained fixed after pressing plate puts in place, makes pressing plate and bearing keep more remote, has guaranteed antenna rotation reliability; The present invention is simple in structure, is convenient to manufacture.
Description of drawings
Fig. 1 is for adopting antenna locking view of the present invention;
Fig. 2 is a locking state structural representation of the present invention;
Fig. 3 is a release condition structural representation of the present invention;

Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, owing to will experience the mechanical environment of emission process complexity, it is firm that antenna need utilize convertible locking releasing device of the present invention to lock when emission, and this device connects the rotating part and the standing part of antenna.As shown in Figure 2, the present invention is by adaptor 1, rotating shaft 2, torsion spring 3, pressing plate 4, check lock lever 5, position-limiting cover 6, spring shield 7, spring 8, locking nut 9, ball pad 10, bearing 11 and priming system 12 are formed, adaptor 1 is connected with the antenna rotating part, bearing 11 is connected with the antenna standing part, adaptor 1 axially is connected with pressing plate 4 by rotating shaft 2, torsion spring 3 is installed in the rotating shaft 2, and apply torsion by adaptor 1 and pressing plate 4, pressing plate 4 is connected by check lock lever 5 with bearing 11, one end and the bearing 11 of check lock lever 5 are connected, the other end is successively by ball pad 10, locking nut 9, spring 8 is connected with pressing plate 4 lockings with spring shield 7, have on the bearing 11 separation that priming system 12 is used for tie down screw 5 is housed, the impulsive force that produces when position-limiting cover 6 being installed on pressing plate 4 being used to transmit check lock lever 5 and being cut off, spring 8 is used to be cut off and is maintained fixed after screw portion puts in place, wherein the installation site of priming system 12 is as far as possible by last, exposes the short reliable separation of being convenient to pressing plate 4 and bearing 11 of the part of pressing plate 4 after check lock lever 5 is cut off.Above-mentioned priming system 12 can adopt cutter or adopt blasting bolt or adopt the distinguish nut all can realize cutting off check lock lever 5.
During locking state, by locking nut 9 pad 10 of trapping the ball, and then pressing plate 4 and bearing 11 compressed binding, bearing 11 is connected by rotating shaft 2 with adaptor 1, and rotating shaft 2 is subjected to limiting the circumferential degree of freedom of antenna from the bending of adaptor 1 and shearing, thereby locks antenna.After receiving the release telemetered signal, priming system 12 detonates and cuts off check lock lever 5, cut check lock lever 5, spring 8 and when cutting impulsive force effect under, move upward together with spring shield 7, put in place impact force action in position-limiting cover 6, and rely on spring 5 to remain secured to position-limiting cover 6 times, and pressing plate 42 rotates under the double action of torsion spring 3 and the position-limiting cover 6 suffered impulsive forces that are connected with it around the shaft in the direction of arrows, and it is spacing that pressing plate 4 forwards a back connected piece 1 to, moment by torsion spring 3 remains secured to the present position that puts in place, thereby finish release movement, as Fig. 3, shown in Figure 4, device after the release, the parts that are connected with the antenna rotating part rotate together with antenna.
The unspecified content of the present invention is a technology as well known to those skilled in the art.
