Description

Technical Field

[0001] This invention relates to the field of radar antenna technology, specifically to a rapid erection and dismantling mechanism for a heavy-duty, high-rigidity digital array radar antenna. Background Technology

[0002] Digital array radar has advantages such as flexible resource scheduling, strong anti-interference capability, and easy realization of multi-functional intelligence. With the continuous improvement of technology maturity and the significant reduction of component costs, radar systems are developing towards broadband and multi-functionality, and applications are constantly expanding into traditional fields such as meteorological and air traffic control radar.

[0003] Rapid erection and dismantling mechanisms for heavy radar antennas mainly fall into two structural categories: hydraulic multi-link lifting mechanisms and hydraulic inverting lifting mechanisms. For example, Chinese invention patent application CN201710718481.3 discloses a hydraulic multi-link lifting mechanism for radar antennas. While this mechanism, through the combined movement of multiple hydraulic cylinders driving the back frame and multiple supporting links, can automatically erect and dismantle an antenna measuring 19.2m in length and carrying a 17-ton load, its inherent rigidity is weak, resulting in significant array deformation under wind loads, thus affecting radar detection accuracy. Hydraulic inverting lifting mechanisms primarily use dual hydraulic cylinders to directly and synchronously drive the antenna for lifting and lowering. Although they offer high automatic erection and dismantling efficiency, their load-bearing capacity and rigidity are limited, failing to meet the requirements for erecting heavy, high-rigidity radar antennas.

[0004] A new type of airport airway support radar based on digital array technology adopts a dual-polarization, digital array system. A single radar unit has multiple functions including meteorological, air traffic control, and non-cooperative target tracking. The antenna array has an aperture of 8.6m × 9.1m, consists of four sub-arrays, and weighs a total of 25 tons. After installation, the array surface accuracy is better than 2mm. The setup and dismantling mechanism is required to quickly position, assemble, and erect the antenna, and drive it at a maximum speed of 6 rpm in wind conditions of 25m / s. It must also be able to operate stably at any angle within a 90° elevation range, and maintain accuracy during rapid relocation and repeated installation. As analyzed above, existing rapid setup and dismantling mechanisms for heavy radar antennas are all insufficient to meet these requirements due to their inherent limitations. Summary of the Invention

The inner ring of the slewing bearing is screwed onto the base, and the turntable is screwed onto the outer ring of the slewing bearing. The motor reducer is mounted on the semi-trailer platform via the eccentric sleeve. The rotary assembly is installed between the turntable and the base. The lifting hydraulic system and the lifting control box are installed at the tail of the turntable.

[0014] The present invention discloses a rapid erection and dismantling mechanism for a heavy-duty, high-rigidity digital array radar antenna. The semi-trailer platform includes a frame, a traveling mechanism, six anti-overturning booms, four heavy-duty leveling legs, six anti-overturning legs, outriggers, a transport support mechanism, a platform hydraulic system, an azimuth servo control box, an erection servo control box, a platform electrical distribution cabinet, and a liquid cooling source. The traveling mechanism is installed on the bottom surface of the rear of the frame. The four heavy-duty leveling legs are installed on the front and rear sides of the frame. The six anti-overturning legs are distributed around the frame via the six anti-overturning booms. The transport support mechanism and the erection servo control box are installed at the rear of the vehicle. The platform hydraulic system is installed on the gooseneck of the frame. The azimuth servo control box, the platform electrical distribution cabinet, and the liquid cooling source are installed on the upper rear surface of the frame.

[0015] The present invention discloses a rapid erection and dismantling mechanism for a heavy-duty, high-rigidity digital array radar antenna. The transport support mechanism includes a bracket, a locking hook, a tilting hydraulic cylinder, a hook-action cylinder, and a position sensor. The bracket is hinged to the rear of the semi-trailer platform, the locking hook is hinged to the upper rear side of the bracket, the cylinder of the tilting hydraulic cylinder is hinged to the semi-trailer platform, and the piston rod is hinged to the bracket. The cylinder of the hook-action cylinder is hinged to the bracket, and the piston rod is hinged to the locking hook.

[0016] With the above structure, compared with the prior art, the beneficial technical effects of the present invention are reflected in the following aspects:

[0017] 1. This invention's rapid setup and dismantling mechanism is based on a heavy-duty automatic leveling and anti-tipping semi-trailer platform. It employs a large-diameter turntable, a high-rigidity antenna back frame, and two sets of horizontal support deployment mechanisms as the support structure for four sub-arrays, totaling 25 tons. A set of arbitrary-stroke locking lifting cylinders and an angle encoder drive the antenna to any working position within the range of 0–90°. A KFH 125 hydraulic locking device installed between the piston rod and cylinder barrel of the lifting cylinder mechanically grips the piston rod, enabling the antenna to operate continuously and stably at any elevation angle for extended periods. The rapid setup and dismantling mechanism possesses sufficient rigidity and strength. After the radar antenna is erected, it can operate normally at a maximum speed of 6 rpm in a 25 m / s wind environment, and the system remains undamaged in a 35 m / s wind environment.

[0018] 2. The rapid setup and dismantling mechanism of this invention incorporates antenna longitudinal guide grooves, antenna transverse guide rollers, and surface accuracy adjustment mechanisms on the antenna back frame and the assembly of two sets of cross braces. When installing the four sub-array antennas, the antenna longitudinal guide grooves achieve vertical repeatability, and the antenna transverse guide rollers achieve horizontal repeatability. During the initial antenna installation, 32 surface accuracy adjustment mechanisms on 10 cross braces adjust the surface accuracy of the four sub-array antennas to within 2mm. Then, each surface accuracy adjustment mechanism is locked, and finally, a series of bolts secures each sub-array to the antenna back frame and the two sets of cross braces. This rapid setup and dismantling mechanism enables rapid repeatability, assembly, or disassembly of the four sub-arrays during radar relocation. After repeated disassembly and assembly, the repeatability of the four antenna sub-arrays is within ±0.3mm, and the surface accuracy of the antenna array is better than 2mm, solving the problem of repeatability during the rapid setup of heavy, high-rigidity digital array radar antennas.

[0019] 3. The support structure of the antenna array of the rapid erection and dismantling mechanism of this invention is composed of two sets of horizontal support unfolding mechanisms, ten sets of horizontal support locking mechanisms, and an antenna back frame. The ten horizontal supports are rapidly unfolded by four unfolding hydraulic cylinders and eight connecting rods. The twenty locking pins of the horizontal support locking mechanism are locked to the antenna frame after unfolding by the ten driving hydraulic cylinders. The entire unfolding and locking action can be completed in just two minutes under the automatic control of a servo hydraulic system. This not only reduces manual operation but also significantly shortens the erection time and improves the rapid relocation capability of the radar antenna.

[0020] 4. The rapid erection and dismantling mechanism of this invention uses multiple methods, including horizontal sensors, rotary encoders, and position sensors, to detect motion control signals for the erection and dismantling actions. This enables automatic leveling of the semi-trailer platform, lifting or lowering of the antenna back frame, unfolding or retracting of the cross brace deployment mechanism, locking or unlocking of the cross brace locking mechanism, and flipping and hook locking or unlocking of the transport support mechanism. At the same time, the motion software of each mechanism is interlocked, which improves control accuracy and safety.

[0021] 5. The rapid erection and dismantling mechanism of this invention uses a transport support mechanism installed at the rear of the semi-trailer dismantling platform to support the antenna back frame during transport. After the radar antenna is erected, the transport support mechanism is flipped over to avoid obstructing the radar antenna detection. This not only achieves the functions required for rapid erection, dismantling, and transport of the radar antenna, but also does not affect the radar antenna detection performance.

[0022] 6. The entire setup process of the rapid setup and dismantling mechanism of this invention can be completed by only 6 people within 1 hour. Compared with heavy radar antennas of the same level, which require dozens of people and several hours, the rapid relocation capability is greatly improved. Attached Figure Description
