Abstract
The utility model relates to a servo folding mechanism which belongs to the technical field of an antenna array surface folding device. The servo folding mechanism is composed of an array antenna and a servo folding mechanism. The servo folding mechanism is characterized in that: a left plate and a right plate are symmetrically arranged in front of and behind a high-frequency box frame of the array antenna; an active rocker of the servo folding mechanism is fixedly arranged on the left plate and the right plate respectively; the active rocker is connected with a driven rocker through a connecting rod; the driven rocker is fixedly connected with the high-frequency box frame through a rotating shaft; unit antennas are fixedly arranged on the driven rocker through a supporting board; and the supporting board is fixedly connected with the rotating shaft. The active rocker, the connecting rod and the driven connecting rod form a double-rocker servo folding mechanism. The active rocking rod acts through a hydraulic oil cylinder. The left plate and the right plate are driven for being folded for 90 DEG. Through the connecting rod and the driven rocker, on condition that no power transmission device is added, downward folding of the unit antenna can be performed in a servo manner, thereby shortening erecting/withdrawing time, reducing number of transmission and power devices, causing free folding and unfolding of the planar array antenna, and realizing stable operation.
Description
Technical field
The utility model relates to a kind of servo-actuated fold mechanism, belongs to antenna array folding device technical field.
Background technology
Large-scale antenna is by highway, railway transportation, and its height and width are the maximum bottlenecks of transportation.How farthest to reduce large-scale antenna shipping height, dwindle transportation width, meet movement requirement, be a difficult problem of pendulum in face of the designer.On antenna array, design and installation fold mechanism can meet movement requirement substantially.Fold mechanism is but installed and will be avoided the impact of structural member on telecommunications index on the one hand, will consider to connect between plate on the one hand the impact of the turning of cable radius on hinge and element antenna, more should consider the reliability that fold mechanism expansion bracket is put on the other hand.
Summary of the invention
The purpose of this utility model is, provide a kind of can servo-actuated downward folding unit antenna, shorten and set up, remove between the time receiving, reduce transmission and power set, reliable operation, retractable is smooth and easy, while solving existing planar array antenna by highway, railway transportation, the transfinite servo-actuated fold mechanism of problem of profile.
The utility model is to realize by the following technical solutions above-mentioned purpose
This servo-actuated fold mechanism consists of array antenna, servo-actuated fold mechanism, it is characterized in that: array antenna comprises left plate, high-frequency box frame, right panel piece; Before and after high-frequency box frame, be symmetrically installed with left plate, right panel piece; Servo-actuated fold mechanism comprises drive crank, connecting rod, driven rocking bar; Drive crank is packed in respectively on left plate, right panel piece, drive crank is by connecting rod and driven rocking bar attaching, driven rocking bar is connected with high-frequency box framework fixed installing by rotating shaft, on driven rocking bar, by supporting bracket, is fixed with element antenna, and supporting bracket is fixedly mounted with and is connected with rotating shaft.
The utility model beneficial effect is compared with prior art
This servo-actuated fold mechanism adopts drive crank, connecting rod, driven rocking bar to form the servo-actuated fold mechanism of double rocking lever, by hydraulic jack, drive crank is moved, and drives left plate, right panel piece to do 90 ° and folds; By connecting rod, driven rocking bar, in the situation that not increasing actuating unit, can servo-actuatedly carry out the folding of element antenna downwards, shorten and set up/remove between the time receiving, reduce transmission and power set, make planar array antenna retractable freely, working stability is reliable, effectively improved transportation suitability, while having solved existing planar array antenna by highway, railway transportation, the problem that profile transfinites.

Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention are described in detail:
This servo-actuated fold mechanism consists of array antenna, servo-actuated fold mechanism, and array antenna comprises left plate 1, high-frequency box frame 2, right panel piece 3; High-frequency box frame 2 front and back are symmetrically installed with left plate 1, right panel piece 3; Servo-actuated fold mechanism comprises drive crank 4, connecting rod 5, driven rocking bar 6; Drive crank 4 is packed in respectively on left plate 1, right panel piece 3, drive crank 4 is by connecting rod 5 and driven rocking bar 6 attachings, driven rocking bar 6 is fixedly mounted with and is connected with high-frequency box frame 2 by rotating shaft 7, on driven rocking bar 6, by supporting bracket 9, is fixed with element antenna 8, and supporting bracket 9 is fixedly mounted with and is connected with rotating shaft 7.(referring to accompanying drawing 1～6)
Because railway transportation exists the height upper limit, and the tail cable of element antenna 8 folds interference rear and that high-frequency box frame 2 exists, determined the height lower limit of element antenna 8, therefore, left plate 1, right panel piece 3 drive drive crank 4 to rotate 90 ° under the effect of hydraulic cylinder 10, in this process, the element antenna 8 of left plate 1 is along with driven rocking bar 6 rotates 35 °, and the element antenna 8 of right panel piece 3 is along with driven rocking bar 6 rotates 33 °.
The process of antenna array from deployed condition to travel position is: the drive crank 4 of right panel piece 3 turns clockwise 90 ° under the driving of hydraulic cylinder 10, and drive driven rocking bar 6 to turn clockwise 33 ° by connecting rod 5, and the supporting bracket 9 of element antenna 8 is packed in rotating shaft 7, also along with 33 ° of driven rocking bar 6 rotations, shrink and arrive below railway transportation height boundary.
In like manner, left plate 1 drives 35 ° of element antenna 8 rotations by connecting rod 5, arrives below railway transportation height boundary.
This servo-actuated fold mechanism utilizes the folding power of left plate 1, right panel piece 3, servo-actuated the folding downwards of the super wide territory element antenna 8 of superelevation that carry out, shorten and set up/remove between the time receiving, reduce transmission and power set, improve the problem that large planar array antenna transfinites when train transportation and railway transportation that solved.
The above is the embodiment of this utility model, above-mentioned not illustrating is construed as limiting flesh and blood of the present utility model, person of an ordinary skill in the technical field can make an amendment or be out of shape above-mentioned embodiment after having read this specification, and does not deviate from essence of the present utility model and scope.
