Abstract
The utility model discloses a radar antenna pitching feed screw transportation unlocking mechanism which comprises a pitching feed screw, a rotation table supporting base and a pin shaft, wherein a kidney round pin hole is arranged on the rotation table supporting base, the pitching feed screw and a contact surface of the rotation table supporting base are circular arc-shaped structures, and the pitching feed screw is located in the unlocking state or the locating state through the adjustment of the circular arc contact surface and the kidney round pin hole. The radar antenna pitching feed screw transportation unlocking mechanism enables a radar antenna to automatically realize unlocking and locating functions of the pitching feed screw in the pitching movement process, alleviates alternating stress forced on the driving system, the rotation table and the radar antenna, and prolongs the service life of the product.
Description
Technical field
The utility model discloses a kind of radar antenna pitching screw mandrel transportation release mechanism, relates to the elevating movement control of radar antenna, especially can realize the automatic unlocking of pitching screw mandrel under travel position of radar antenna, slows down and continues the alternate stress impact.
Background technology
The conventional at present radar antenna that adopts mechanical pitching, antenna is in to bow and puts or face upward configuration state under travel position, and antenna one end connects with the turntable bearing by the pitching drive system, and the other end adopts fixed support or resiliency supported and shipping platform to link.In transportation, shipping platform can produce distortion with the variation of road conditions, cause the two ends of antenna to produce relative displacement, and the effect of the power of generation, make pitching drive system, turntable and radar antenna etc. continue to be under the alternate stress environment, cause properties of product and life-span to be reduced, will damage pitching drive system, turntable and radar antenna in some cases.
Chinese invention patent 200610161299.4 discloses a kind of its technical characterictic of radar antenna base elevating mechanism and has been: be made of bearing and gantry column; The gantry column front end is installed radar antenna base, the strong point and the back strong point before the rear end is provided with; The back strong point connects with bearing hinge, and the hinged power set of the preceding strong point, power set promote gantry column and rotate up and down around the back strong point.
This device strong point and bearing, the strong point and power set are hinge-coupled, influenced by alternate stress, and anti-stress impact ability is low, influence product useful life.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the defective that prior art exists, slow down or eliminates pitching drive system, turntable and radar antenna suffered lasting alternate stress under travel position, thus raising product reliability and life-span.
The utility model for realizing the technical scheme that purpose is taked is: a kind of radar antenna pitching screw mandrel transportation release mechanism, include pitching screw mandrel, turntable bearing, bearing pin, it is characterized in that: on the pitching screw mandrel circular pin hole is arranged, have the oval shaped pin hole on the turntable bearing, both connect by bearing pin, and can carry out freely rotating; Pitching screw mandrel tail end is designed to the convex structure, and the contact-making surface of turntable bearing and pitching screw mandrel tail end is designed to the arcs of recesses structure.
Radar antenna of the present utility model is in travel position following time, and the pitching screw mandrel is in the configuration state of bowing, and concave arc does not contact with convex arc, the pitching screw mandrel can be free to slide along about the oval pin-and-hole, bearing pin also can slide thereupon together, can effectively alleviate alternate stress and impact, and realizes unlocking function.
In radar antenna in running order following time,, the pitching screw mandrel rotates up, and is in to face upward configuration state, and concave arc closely contacts with convex arc, pushes bearing pin the left end of oval pin-and-hole to, and therefore screw mandrel is positioned, and can not horizontally slip, and reaches the requirement of operating state.
The utility model has following advantage compared to existing technology:
(1) on the basis of the function that realizes prior art, can slow down or eliminate pitching drive system, turntable and radar antenna suffered lasting alternate stress under travel position, thus raising product reliability and life-span.
(2) conversion of the positioning function of the unlocking function of travel position and operating state along with the pitching of radar antenna is finished automatically, does not need manual intervention.

Embodiment
The explanation of mark in the accompanying drawing: pitching screw mandrel 1, bearing 2, bearing pin 3, pin-and-hole 4, convex 5, arcs of recesses 6, pin-and-hole 7.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment as shown in Figure 1, radar antenna pitching screw mandrel transportation release mechanism is made up of pitching screw mandrel 1, turntable bearing 2 and 3 three members of bearing pin.Pitching screw mandrel 1 has pin-and-hole with turntable bearing 2 and links together by bearing pin 3, and pin-and-hole 7 is circular on the pitching screw mandrel 1, and pin-and-hole 4 is an oval shape on the turntable bearing 2.Pitching screw mandrel 1 tail end is designed to convex 5 shown in Figure 1, turntable bearing 2 and pitching screw mandrel 1 tail end contact-making surface are designed to arcs of recesses 6. shown in Figure 1
The unlocking function of this mechanism under travel position seen Fig. 2 and shown in Figure 3.Pitching screw mandrel 1 is in the limit on the left position among Fig. 2, and bearing pin 3 is in oval shaped pin hole 4 left ends simultaneously; Pitching screw mandrel 1 is in the limit on the right-right-hand limit position among Fig. 3, and bearing pin 3 is in oval shaped pin hole 4 right-hand members simultaneously, screw mandrel can left and right sides extreme position with interior free movable, thereby the alternate stress that reduces in the transportation impacts, and realizes unlocking function.
The positioning function of this mechanism under in working order seen shown in Figure 4.Pitching screw mandrel 1 is by rotating to an angle among Fig. 4, make radar antenna enter operating state, the convex 5 of screw mandrel tail end matches with turntable bearing 2 arcs of recessess 6 simultaneously, closely contact, promote the left end that bearing pin 3 slides to oval shaped pin hole 4, pitching this moment screw mandrel 1 is positioned, and can not horizontally slip the state that the work that reaches is required.
When radar antenna transforms to travel position (or transform to operating state from travel position) from operating state, this mechanism can be from state transformation shown in Figure 4 to Fig. 2, state shown in Figure 3 (or from Fig. 2, state transformation shown in Figure 3 to state shown in Figure 4), whole conversion process is realized by mechanism's self-characteristic, be need not to carry out manual intervention.
