Abstract
The utility model aims to provide an automatic guiding propeller stirring device, and solves the technical problem that propeller stirring operation is inconvenient in the prior art. The automatic guiding propeller stirring device comprises a rotating shaft and a lever stirring component, wherein the rotating shaft is mounted on the inner side at the top of an emitting box in a position near a box door; the lever stirring component comprises a blade supporting rod and a propeller stirring blade which is coaxially connected with the blade supporting rod through a torsion spring; the middle of the blade supporting rod adopts a return spring structure, and can drive the front part of the blade supporting rod to deviate from the axial line of the blade supporting rod under the action of external torque; and the rear part of the blade supporting rod is fixedly connected with the rotating shaft perpendicularly, so as to ensure that the rotating shaft can drive the lever stirring component to rotate. According to the automatic guiding propeller stirring device, a propeller in any position can be stirred to be smooth, so as to avoid interference between the propeller of an airplane and a box body, and ensure that the airplane can enter into the box smoothly; and the operation is mechanical completely, and the propeller stirring operation can be guided automatically due to the relative positions of the propeller stirring component and the propeller.
Description
Technical field
The utility model relates to a kind of mechanical type and dials the oar device, is particularly useful for the oar of dialling to the unmanned plane screw propeller.
Background technology
When aero-engine stopped, screw propeller was to be parked in the optional position at random, and when screw propeller stops and the angle of level attitude during greater than certain value, screw blade can exceed the firing box upper side frame, and aircraft can not take in the case.If with a bar screw propeller is allocated to the state near level attitude, aircraft could be taken in the case.Because there is a bigger end face screw propeller end, when driving lever is allocated to this position, can produce the dead point, screw propeller can not sway, if strength is excessive, and also can the wrap up screw propeller.
General single box emission coefficient can adopt the artificial oar of dialling that aircraft is regained; What adopt now is the many casees of multilayer; Be difficult to observe the state of the properller that is in middle and high layer firing box; Adopt the artificial oar mode of dialling directly to touch screw propeller, therefore need a kind of automatic group of this problem of oar device solves.
The utility model content
The utility model aims to provide a kind of group oar device of homing guidance, dials the technical matters of oar inconvenience to solve prior art.
The technical scheme of the utility model is following:
A kind of group oar device of homing guidance; Comprise turning cylinder and driving lever assembly; Said turning cylinder is installed on the position of firing box inside top near chamber door; Said driving lever assembly comprises blade pole and dials the blade sheet through torsion spring and the coaxial bonded assembly of blade pole that the middle part of blade pole is the retracing spring structure, externally makes the front portion of blade pole depart from the axis of blade pole under the moment loading; The rear portion of blade pole is connected with the turning cylinder vertical fixing, makes that the driving lever assembly can be by the turning cylinder driven rotary.
Above-mentioned turning cylinder can be the turning cylinder by the retarder assembly of electric motor drive.
Above-mentioned transmission shaft is dialled plane, blade sheet place during preferably perpendicular to normality.
The utlity model has following advantage:
1, can move flat the screw propeller that is in the optional position suitablely, avoid properller and casing to interfere, make the smooth cartonning of aircraft.
2, adopt mechanical operation completely, rely on the relative position of dialling oar assembly and screw propeller to guide automatically and dial oar.
Description of drawings
Fig. 1 a---Fig. 1 c is the structural representation of the utility model; Wherein, Fig. 1 a is front view (horizontal plane), and Fig. 1 b is a birds-eye view, and Fig. 1 c is a right elevation.
Fig. 2 a, Fig. 2 b are group oar assembly scheme drawing of the utility model; Wherein, group blade sheet compares to Fig. 1 and has turned over 180 degree, and Fig. 2 a is a birds-eye view, and Fig. 2 b is a front view.
The drawing reference numeral explanation:
1-driving lever assembly; The 2-electric motor assembly; 3-retarder assembly; The 31-turning cylinder;
20-blade pole; The front portion of 201-blade pole (swing arm parts); The 22-spline housing; The 23-spring; 24-dials the blade sheet; The 25-locating part; The 26-sheath; The 27-torsion spring; The 28-blanking cover.
The specific embodiment
A kind of screw propeller that the utility model provides is dialled the oar device can be used for the box unmanned aerial plane launching system of accumulating; Before after unmanned plane is accomplished training, test, regaining in the firing box; Use the utility model to move flat the screw propeller that is in the optional position suitable; Avoid properller and casing to interfere, make the smooth cartonning of aircraft.
Below in conjunction with accompanying drawing this device is detailed:
The utility model is equipped with the electric reducer structure of dialling the oar blade by one to be formed, and dials the oar blade and is installed on the output shaft (turning cylinder) of deceleration electric mechanism through blade pole.
Group blade sheet of the utility model is under external torque, to rotate to a direction around blade pole, and can relies on the torsion spring self-return that blade pole also can upwards be lifted an angle under external force simultaneously, and retracing spring is arranged.Screw propeller is dialled the oar device and is installed on the upper side frame of firing box inside top near chamber door.Before aircraft income case; Dial the oar device and drive group blade sheet along the revolution of firing box inside top, group blade sheet outwards goes to and will touch properller, if the contact site is the lower side of screw propeller body; Then dial the blade sheet as straight-bar, directly stir screw propeller and turn near level; If the contact site is the screw propeller end, then dials the slurry blade and upwards rotate, and guide blade pole to lift automatically along the screw propeller end; Cross dead center position; After dialling the blade sheet and crossing the screw propeller end, pole leans on retracing spring and gravity that screw propeller is depressed, and makes it near level attitude.Like this, no matter propeller is in any angle when dialling slurry, dials blade sheet total energy safety and is allocated to level to screw propeller smoothly.
The deceleration electric mechanism of this device can be common Worm-gear type or other forms of speed reduction gearing.
The utility model has solved the problem of the automatic smooth-going screw propeller in the unmanned plane recovery box of multilayer accumulating formula unmanned aerial plane launching system; Make the unmanned plane receipts case of the multiple-layer box type accumulating unmanned aerial plane launching system of control cluster far away accomplish automation, guaranteed aircraft safety receipts case.
