Description

Technical Field

[0001] This utility model relates to the technical field of vehicle-mounted mobile antenna equipment, and in particular to a lifting and lowering device for container-type medium and large aperture parabolic antennas, which enables the antenna to be laid down for storage during transportation and quickly erected during operation. Background Technology

[0002] Large vehicle-mounted parabolic antennas, due to their high mobility and strong battlefield adaptability, have become a key component of modern aerospace telemetry and communication equipment. To meet the stringent requirements of various transportation modes such as highways and railways, and to achieve rapid deployment and dismantling, these antennas generally adopt a design scheme with an azimuth-elevation two-axis mount plus a third axis (i.e., a horizontal axis). Containerized antennas, as an important form, integrate the entire antenna system within a standard shipping container, not only possessing high mobility but also significantly improving the equipment's concealment and battlefield survivability.

[0003] Currently, there are two main technical solutions for the design of container-type antenna lifting and lowering devices:

[0004] The first type of solution: low-support base mounting. This solution directly mounts the antenna's horizontal axis (third axis) in a hinged support at the bottom of the container. Its advantages lie in its simple structure and direct transmission. However, to ensure the antenna reflector is above the container's top wall in the upright position to avoid obstruction, the antenna support column must be designed to be very long. This results in an excessively large overall horizontal dimension of the antenna and support column during horizontal transport, requiring even longer containers to accommodate them. This severely reduces the equipment's maneuverability and maneuverability, increases the overall vehicle weight and inertia, and affects transport stability and leveling accuracy.

[0005] The second type of solution: Lifting platform type. This solution mounts the entire antenna mount (including azimuth and elevation axes) on a heavy-duty lifting platform. During operation, the lifting platform first raises the antenna to a predetermined height before performing alignment. While this solution effectively reduces the height of the support columns and shortens the container length, it introduces a complex lifting mechanism, guiding devices, and corresponding hydraulic or electric systems. This not only significantly increases the overall weight, manufacturing cost, and power consumption of the system, but also introduces new potential points of failure, reducing the system's reliability. Furthermore, the lifting mechanism requires regular maintenance, increasing the total life-cycle cost.

[0006] In summary, existing technologies struggle to simultaneously achieve both high reliability and compact container structure with high equipment mobility. Therefore, there is an urgent need in this field for a novel lifting and lowering device design to fundamentally resolve these contradictions. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a containerized antenna high-fulcrum deployment and retraction device. This device aims to achieve reliable housing and rapid deployment and retraction of the antenna system within a miniaturized container by optimizing the fulcrum position and structural design, without introducing a complex lifting mechanism, ultimately achieving the dual goals of improving equipment mobility and reliability.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A container-type antenna high-fulcrum raising and lowering device includes a container and a raising and lowering device disposed therein; the raising and lowering device is a rigid motion mechanism capable of achieving precise angle control, which includes a drive mechanism, a support column, a hinge support and a base.

[0010] The base is fixedly installed on the upper part of the side wall frame of the container, and its installation position is much higher than the bottom surface of the container, forming a high support point;

[0011] The lower end of the support column is hinged to the base through the hinge support, so that the support column can rotate around a horizontal axis.

[0012] One end of the drive mechanism is hinged to the bottom of the container, and the other end is hinged to the side of the support column;

[0013] The antenna mount is fixedly installed on the upper end face of the supporting column;

[0014] The hinge support is a combined component, which includes a pin, a flange self-lubricating copper sleeve, an angle detection element, and a locking component; the flange self-lubricating copper sleeve is fixed in the connecting hole at the lower end of the support column, forming a rotating pair with the pin; the angle detection element is a rotary transformer, installed at the end of the pin; the locking component is a lock nut or lock screw, used to axially fix the pin.

[0015] The drive mechanism is selected from one of an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder, preferably an electric cylinder.

[0016] Furthermore, there are two hinge supports, symmetrically arranged on the left and right sides of the lower end of the support column; of the two hinge supports, one is equipped with the rotary transformer and the locking nut, and the other is equipped with the locking screw.

[0017] Beneficial effects

[0018] Compared with the prior art, the present invention has the following significant advantages:

[0019] Compact structure and excellent mobility: This invention places the hinge point (lifting / lowering axis) of the lifting / lowering device at the upper end of the container side wall frame, forming a "high fulcrum" structure. This design significantly increases the effective height of the support column when the antenna is erected, thereby significantly shortening the physical length of the support column while ensuring the antenna reflector surface is above the container top. The shortened column directly leads to a smaller horizontal projection size when the antenna is lowered, allowing the use of shorter standard containers, greatly improving the equipment's mobility and maneuverability, and reducing transportation costs and difficulties.

[0020] High reliability and easy maintenance: This invention abandons the complex and cumbersome lifting platform mechanism, returning to a simple and reliable rotary lifting principle. The entire transmission chain consists only of an electric cylinder and a hinge support, resulting in a simple structure and low failure rate. The flange self-lubricating copper sleeve used in the hinge support has excellent wear resistance and self-lubricating properties, requiring no additional lubrication and maintenance, and has a long service life. The entire device has few moving parts, low maintenance requirements, and significantly improves the overall reliability and environmental adaptability of the system.

[0021] Precise control and high safety: By integrating a rotary transformer into the high-fulcrum hinge support, the antenna's tilting angle can be detected and controlled in real time and with precision, achieving self-locking upon positioning. This avoids the impact caused by mechanical limits, ensuring smooth and controllable movement and high safety.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0034] (a) Structural composition:

[0035] See Figures 4 to 6 The container-type antenna high-support point lifting and lowering device provided by this utility model can be divided into two main parts: container 1 and lifting and lowering device integrated therein.

[0036] The lifting and lowering device is a rigid motion mechanism capable of precise angle control, which can be further subdivided into the following core components:

[0037] Drive mechanism: In this embodiment, an electric cylinder 2 is specifically used, which includes a cylinder body, a piston rod, and a built-in motor and transmission mechanism.

[0038] Load-bearing and transmission structure: including support column 3 and base 5.

[0039] The core rotary connection structure, namely the hinge support 4, is a composite component composed of multiple sub-parts, including: pin 7, which serves as the central axis of rotary motion; flange self-lubricating copper sleeve 13, which acts as a sliding bearing and is fitted onto the pin 7; angle detection element, specifically a rotary transformer 11, used to detect the rotation angle; locking components, including a locking nut 12 and a locking screw 8, used for axial fixation; and auxiliary components, including washers 6 and 9 and a dust cover 10.

[0040] (ii) Connection relationship:

[0041] The components form a complete and reliable rigid kinematic chain in the following way:

[0042] Connection between base 5 and container 1: Base 5 is a rigid component, which is fixedly connected to the upper inner side of the side wall frame of container 1 by welding or high-strength bolts. This installation position is much higher than the bottom surface of the container, forming the "high fulcrum" of the entire device.

[0043] The hinged connection between the support column 3 and the base 5: The lower end of the support column 3 is hinged to the base 5 through two symmetrically arranged hinge supports 4. Specifically, coaxial connecting holes are machined on the left and right sides of the lower end of the support column 3, and the flange self-lubricating copper sleeve 13 is pressed into these connecting holes with an interference fit. The base 5 has a mounting hole coaxial with the flange self-lubricating copper sleeve 13. The pin 7 passes sequentially through the mounting hole on one side of the base 5, the washer 9 on one side, the flange self-lubricating copper sleeve 13 on the support column 3, the washer 9 on the other side, and finally into the mounting hole on the other side of the base 5. Thus, the support column 3 can rotate flexibly relative to the base 5 through the cooperation of the flange self-lubricating copper sleeve 13 and the pin 7.

[0044] The assembly relationship of the hinge support 4 itself includes:

[0045] Axial fixation: In the two hinge supports 4, the pin 7 of one of them is machined with external threads and locked to the washer 6 by the lock nut 12; the pin 7 of the other is fixed by the radially driven locking screw 8 to prevent it from moving axially.

[0046] Angle detection: On the side with the locking nut 12, the rotary transformer 11 is fixedly installed at the end of the pin 7 by screws and can rotate synchronously with the pin, thereby accurately measuring the rotation angle of the support column 3.

[0047] Dust protection: The dust cover 10 is fixed to the support column 3 with screws, covering the entire hinge part, effectively preventing dust, mud and moisture from entering, and ensuring the long-term reliable operation of the rotating pair.

[0048] Connection of drive mechanism 2: The end of the cylinder body of the electric cylinder 2 is hinged to the bottom plate of the container 1 via lugs and pins. The end of its piston rod is also hinged to the side of the lower part of the support column 3 via lugs and pins. The two hinge points of the electric cylinder 2 and the hinge point (high fulcrum) of the support column 3 together constitute a stable planar linkage drive mechanism.

[0049] Antenna mount installation: The entire antenna mount (including azimuth, elevation axis and antenna reflector, not shown in the figure) is fixedly mounted on the upper surface of the support column 3 via its base plate.

[0050] (III) Working principle and motion process:

[0051] This device is based on the lever principle, and the linear motion of an electric cylinder drives the support column to rotate around the highest fulcrum. The motion process is as follows:

[0052] The process of setting up the work status (Collection → Work):

[0053] When the control system receives the "erect" command, the piston rod of the electric cylinder 2 begins to extend outward under the drive of the motor. Since the piston rod is hinged to the side of the support column 3, and the rotation center (high fulcrum) of the support column 3 is located at its lower end, the thrust of the piston rod will exert a clockwise (or even) rotational force on the support column 3 around the pin 7. Figure 1 (Taking a perspective as an example) A strong rotational torque. Driven by this torque, the supporting column 3 drives the entire antenna mount at its top to rotate smoothly and uniformly upwards. During this process, the rotary transformer 11 feeds back the rotation angle signal of the supporting column 3 to the control system in real time. When the angle reaches the preset vertical working position (e.g., perpendicular to the bottom of the container), the control system immediately sends a stop command to the electric cylinder 2, the electric cylinder 2 locks the piston rod, and the entire antenna system is then stably maintained in the vertical working state (e.g., Figure 1 As shown in the image, the antenna reflector is much higher than the top of the container, with no obstructions.

[0054] The process of lying down in the "Collection" state (Work → Collection):

[0055] When retraction and transfer are required, the control system issues a "lie down" command, and the piston rod of electric cylinder 2 begins to retract. The pulling force of the piston rod is converted into a torque that causes the support column 3 to rotate counterclockwise around the pin 7. Under the traction of electric cylinder 2, the support column 3 and its antenna mount smoothly and controllably lie down into the container. The rotary transformer 11 continuously monitors the angle to ensure movement accuracy. When the antenna is fully inside the container and reaches the horizontal storage position, electric cylinder 2 stops and locks. At this time, the antenna is completely stored within the protective space of container 1 (e.g., Figure 2 and Figure 3 As shown), the equipment enters a safe transportation state.

[0056] Through the above-mentioned high-fulcrum design, this utility model replaces the complex and cumbersome lifting motion with a simple and reliable rotational motion, thereby maximizing the utilization of the antenna's working height and improving mobility and reliability while ensuring high performance.

[0057] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention.
