Problems solved by technology

[0002] Radar is often used in air traffic control for monitoring, electronic positioning and identification of flight equipment. The pitching mechanism of the radar can better maintain the connection between the radar antenna and the flying unit. Most of the existing pitching mechanisms combine a part of the antenna The other part is connected to it through a pull rod or telescopic mechanism, and the pitch of the antenna is realized through the action of the pull rod or telescopic mechanism. Since this structure requires multiple components to be linked, any failure of any one of them will cause the pitch mechanism to fail. Operation, especially the rotating joints are mostly made of metal hinges, which are easy to rust if exposed for a long time
[0003] The technical solution provided by the patent document CN105489998B only improves the adjustment assembly, the action of the entire pitch mechanism still needs the linkage of the adjustment assembly and the hinge parts, and the rotation connection is still a metal hinge, and there is also a failure in any of the above-mentioned ones. That will lead to the problem that the pitching mechanism cannot operate

Embodiment 1

[0029] Such as Figure 1-4 As shown, according to the technical solution provided by the present invention: a pitching mechanism for air traffic control radar antenna, including a fixed frame 1, the fixed part 2 on the fixed frame 1 is fixedly connected with the radar antenna 3, and the arc on the fixed frame 1 A tilting mechanism 5 is sleeved on the curved part 4 of the shape.

[0030] Protruding teeth 6 are provided on the inner side of the curved portion 4 , and stepped surfaces 7 are symmetrically provided on the inner wall of the curved portion 4 located on both sides of the convex tooth 6 , and limiting grooves 8 are provided on the outer wall of the curved portion 4 .

[0031] The pitching mechanism 5 includes an upper shell 9 and a lower shell 10 with a circular arc structure, so that the pitching mechanism 5 constitutes a detachable structure, which is convenient for later installation, maintenance and replacement. The upper shell 9 and the lower shell 10 pass through...

Embodiment 2

[0035] Such as Figure 5-6 As shown, on the basis of Embodiment 1, the following technical solution can also be adopted: the fixed frame 1 is designed as a complete ring structure, the inner wall of the fixed frame 1 is still provided with convex teeth 6, and only the lower shell of the U-shaped structure is reserved. body 10, and both sides of the top of the lower housing 10 are provided with installation grooves 15, and the positions of the installation grooves 15 and the positioning grooves 16 on both sides of the fixed frame 1 are corresponding, and the inner sides of the installation grooves 15 are provided with a plurality of third rollers 17. The third roller 17 is matched with the positioning groove 16, so that the fixed frame 1 is not easy to tilt and derail during the rotation process. The limit switch 14 is placed on the side close to the connection with the fixed frame 1, so as to avoid the possibility that the adjustment angle is too large, and the support frame 1...

Abstract

The invention relates to the field of air traffic control radar and discloses a pitching mechanism for an air traffic control radar antenna. The pitching mechanism comprises a fixing frame, wherein afixing portion on the fixing frame is fixedly connected to the radar antenna; an arc curved portion on the fixing frame is sleeved with a pitching mechanism; convex teeth are disposed on the inner side of the curved portion; stepped surfaces are symmetrically disposed on the inner side wall of the curved portion located on both sides of the convex teeth; a stopping groove is disposed on the outerside wall of the curved portion; the pitching mechanism includes an arc upper casing and an arc lower casing; the upper casing and the lower casing are fixedly connected by lock nuts on edges. First and second rollers perform rolling friction on the curved portion, so that the upper and lower casings are not in contact with the curved portion. Further, the first and second rollers are made of nonmetallic materials such as rubber and the like so as to reduce the friction during the operation of the pitching mechanism and improve the transmission efficiency of the pitching mechanism.
