The radar antenna lifting mechanism design is composed of a fixing mechanism, a screw rod, a sliding block, a two-side cushion block, a central cushion block, and a swinging mechanism, wherein the fixing mechanism is fixed on two outer side surfaces of an azimuth box by using fasteners; the screw rod is movably arranged on the fixing mechanism; the sliding block and the screw rod are in threaded connection and then arranged on the fixing mechanism; the two-side cushion block is movably arranged inside the fixing mechanism on the sliding block; the swinging mechanism is movably arranged on the fixing mechanism by using a bolt; the central cushion block is movably fixed on the fixing mechanism by using a bolt; and the upper end surface of the swinging mechanism is detachably arranged and connected with the lifting mechanism. The invention provides an antenna servo device which is simple in structure, convenient to mount and maintain and high in precision. The mechanism of the invention also has advantages of good mechanical structure technological performance, light weight, low cost, good electrical performance and the like, and is particularly suitable for serving as a weather early warning radar antenna servo device.
Description
Technical field
The present invention relates to the radar antenna in meteorological telecommunication field, be specially adapted to the elevating mechanism making weather warning radar antenna.
Background technology
Current large aperture antenna structure generally have employed comparatively complicated Steel material back frame structure, and the important indicator reflector precision of antenna structure will be debugged in erecting bed simultaneously.This structure produces multiple adverse effect, first be that weight is large, the many index of antenna pedestal is as unfavorable in power of motor, decelerator, natural frequency and overall structure etc., secondly complicated structure and Precision adjustment both increase erecting bed workload, and be not easy to maintenance, 3rd, its processing technology is poor, and cost is high.And existing large-scale antenna seat adopts straight-tooth transmission or lead screw transmission more, the former makes huge structure, and the latter's crossing-over rate is low, and speed is slow.Existing antenna pedestal is when keeping in repair in addition, sometimes needs antenna to dismantle, reduces the index safeguarded of system.
Summary of the invention
The technical problem to be solved in the present invention is just to provide that a kind of structure is simple, lightweight, the design of the radar antenna lifting gearing of being convenient to installation and maintenance, and the present invention also to have mechanical structure precision high, the features such as processing performance is good, with low cost, and antenna electrical performance is good.
Technical problem to be solved by this invention is realized by following technical scheme:
A kind of radar antenna lifting gearing design is made up of fixed mechanism, leading screw, slide block, both sides cushion block, center cushion block, swing mechanism, wherein fixed mechanism securing member is fixed on orientation casing two lateral surface, leading screw is movably arranged on fixed mechanism, slide block is arranged on fixed mechanism after connecting with threads of lead screw structure, both sides cushion block activity mat is contained in the fixed mechanism above slide block, swing mechanism bolt is movably arranged on fixed mechanism, center cushion block bolt is movably fixed on fixed mechanism, and the removable installation in movable stand upper surface is connected with elevating mechanism.
Beneficial effect of the present invention:
1. elevating mechanism of the present invention, can carry out maintain and replace under the condition not dismantling antenna, improves antenna maintainability.
2. structural manufacturing process performance of the present invention is good, and mechanical precision is high, and replaceable units modular construction is reasonable in design, is convenient to very much processing and installation and maintenance.
Accompanying drawing explanation
Fig. 1 is antenna and servosystem structural representation in radar system.
Fig. 2 is mounting structure schematic diagram of the present invention.
Embodiment
Referring to figs. 1 through Fig. 2, elevating mechanism 24 of the present invention securing member is fixed on orientation casing 8 liang of lateral surfaces, its effect is when orientation casing 8 inner orientation speed changer 13, pitching casing 9 and orientation casing 8 depart from by the swing mechanism that azimuth mechanism such as azimuth axis 17 grade is risen by elevating mechanism 24 when needing repairing, utilize the space that orientation casing 9 rises, bearing can be split out or orientation transmission mechanism is keeped in repair, keep in repair rear lifting mechanism and fall recovery, maintain and replace can be carried out easily like this under the condition not dismantling antenna, be convenient to antenna maintenance and reduce maintenance load.Elevating mechanism 24 is made up of fixed mechanism 18, leading screw 19, slide block 20, both sides cushion block 21, center cushion block 22, swing mechanism 23.Fixed mechanism 18 securing member is fixedly mounted on the both sides of orientation casing 8, is connected by swing mechanism 23 during maintenance with elevating mechanism 7 with securing member, has keeped in repair the securing member be connected with elevating mechanism 7 of dismantling and has restored.By center cushion block 22 jack-up while rotational lead screw 19 makes slide block 20 produce horizontal movement left, now there is gap between both sides cushion block 21 and swing mechanism 23, gap is encased inside with both sides cushion block 21, rotate backward while leading screw 19 makes slide block 20 produce horizontal movement to the right again by center cushion block 22 jack-up, make to occur gap between center cushion block 22 and swing mechanism 23, gap is encased inside with center cushion block 22, repeat above step just swing mechanism 23 to be risen, pitching casing 9 and orientation casing 8 are departed from, utilize the space that pitching casing 9 rises, parts such as azimuth axis 17 grade can be keeped in repair, reach the object not dismantling antenna maintenance, keep in repair the former mounting structure of rear recovery, antenna is normally worked.Embodiment fixed mechanism 18 adopts the steel plate of commercially available 20 millimeters thick to be machined into italic structure, is convenient to center cushion block 22 jack-up when italic structure slide block moves.Both sides cushion block 21, center cushion block 22 all adopt the steel plate of commercially available 20 millimeters thick to be machined into rectangle strip cushion block structure.Swing mechanism 23 adopts commercially available angle steel material mechanical to be processed into frame structure, swing mechanism 23 jack-up elevating mechanism 7 during maintenance.
The concise and to the point operation principle of the present invention: during Antenna Operation, driving instruction is sent to the servomotor in orientation speed changer 10, pitching speed changer 13 by servo controller, make orientation casing 8, pitching casing 9 produces orientation and elevating movement, antenna direction sends the target with Received signal strength.During the antenna transmission signal of telecommunication, first be electromagnetic wave signal by high the putting transmitting transform electrical signals of external transmitter, feed 1 is transferred to by waveguide 3, feed l by electromagnetic radiation on parabolic reflector 4, by parabolic reflector 4, electromagnetic wave is sent, Received signal strength is then reverse process, by receiver, the electromagnetic wave signal of reception is converted into the reception signal of telecommunication, reaches reception and the transmission of signal of communication.
