Abstract
Description
Technical Field
[0001] This invention belongs to the field of lifting equipment technology, and in particular relates to an antenna lifting platform. Background Technology
[0002] As a crucial mobile communication node, the rapid deployment, high elevation, and precise alignment capabilities of the antenna system in shortwave communication vehicles directly determine communication range and anti-interference performance. Vehicle-mounted antenna systems must achieve multiple objectives within limited space: high elevation, rapid deployment and retraction, and low height restrictions. Therefore, multi-stage electric lifting mast solutions are commonly used to meet road height restrictions, allowing the antenna to be quickly raised to the ideal working height while parked.
[0003] Currently, various vehicle-mounted lifting mechanisms have been applied in such scenarios. Chinese utility model patent CN219507559U discloses a lifting mechanism for military vehicles. This mechanism uses a drive motor and gearbox to drive multi-stage lead screw-nut sleeve assemblies on both sides to lift synchronously, thereby driving the top worktable to achieve vertical movement. Through structures such as rotation-limiting lifting guide blocks and guide rings, it ensures the stability of the lifting process and achieves a large stroke through a multi-stage nested design. This structure has certain advantages in realizing basic lifting functions.
[0004] However, the aforementioned existing technologies have significant limitations when applied to the specific scenario of antenna lifting platforms. First, they only provide a single vertical lifting degree of freedom, while modern antenna systems often require not only elevation during deployment but also azimuth rotation and collapsing / erecting movements during transport. The structure of CN219507559U cannot meet these complex motion requirements. Second, the existing technology uses a rigid or semi-floating connection between the worktable and the lifting column, lacking the ability to automatically, accurately, and reliably connect mechanically and electrically to the antenna body. In field conditions, manual insertion and removal of connectors is inefficient and error-prone, failing to meet the requirements of rapid response. Finally, its overall layout is a vertical tower structure, which occupies a large vertical space when collapsed and stored while the vehicle is in motion, negatively impacting the vehicle's concealment and maneuverability. Summary of the Invention
[0005] This invention addresses the shortcomings of existing technologies by providing an antenna lifting platform.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: an antenna lifting platform, including a platform mounting base plate, and further comprising: The mounting base is fixed to the mounting plate of the platform.
[0007] The main lifting rod is rotatably connected to the mounting base at its bottom via a pivot, and the main lifting rod is composed of multiple nested and retractable main rod sleeves.
[0008] An electric push rod has its cylinder bottom hinged to a push rod mounting seat fixed on the platform mounting base plate, and its extended end hinged to the outer sleeve of the main lifting rod, used to drive the main lifting rod to stand up or fall down around the rotating shaft.
[0009] A pair of lifting frames are symmetrically arranged on the platform mounting base plate and located on both sides of the main lifting rod.
[0010] An antenna erection mechanism is mounted on top of the pair of lifting frames.
[0011] The gimbal is connected to the top of the main lifting rod via a mounting shaft and has the freedom to rotate around the axis of the main lifting rod.
[0012] An automatic antenna connection mechanism is fixed to the top of the gimbal and is used to dock with and lock or detach from an antenna base.
[0013] Furthermore, the antenna erection mechanism includes an erection motor, an antenna bracket, and an electric locking pin; both ends of the antenna bracket are supported on the top of a pair of lifting frames via bearing seats, and the rotation shaft at one end of the antenna bracket is fixedly connected to the output shaft of the erection motor, which drives the antenna bracket to rotate between a vertical state and a folded state; the erection motor integrates a worm gear reducer to achieve self-locking of the antenna bracket in any rotating position.
[0014] Specifically, the first end of the antenna support is connected to a lifting frame, and the second end of the antenna support is connected to another lifting frame.
[0015] Furthermore, the antenna bracket is provided with an electric locking groove, and the antenna base is provided with an ear seat that cooperates with the electric locking groove; the electric locking pin is used to insert when the electric locking groove and the ear seat are aligned, so as to realize the locking between the antenna erection mechanism and the antenna base.
[0016] That is, the electric locking pin 2 is used to insert into the concentric hole between the electric locking groove and the ear seat after they are in place, so as to realize the fixed connection and locking between the antenna erection mechanism and the antenna base.
[0017] Furthermore, the automatic antenna connection mechanism includes a docking base plate fixed to the top of the gimbal; the upper surface of the docking base plate has a guide shaft hole at its center, and multiple connecting shaft holes are evenly distributed around the guide shaft hole; the lower surface of the docking base plate is equipped with an electric pin corresponding to the position of each connecting shaft hole, and the electric pin is used to extend out and pass into the pin hole of the connecting shaft to lock it after the guide shaft hole is aligned and the connecting shaft hole and the connecting shaft of the antenna base are inserted into place.
[0018] Furthermore, the mounting base is equipped with a vertical limit switch, which is triggered when the main lifting rod is raised or lowered to a set angle to control the electric push rod to stop moving.
[0019] Furthermore, the platform mounting base plate is also provided with a main lifting rod bracket for providing support when the main lifting rod is in a collapsed state.
[0020] Furthermore, an antenna connecting plate is fixed on the antenna base; an alignment guide shaft is provided on the antenna connecting plate at the position corresponding to the guide shaft hole, and a connecting shaft is provided at the position corresponding to the connecting shaft hole; the alignment guide shaft is used to first insert into the guide shaft hole for docking guidance.
[0021] Furthermore, it also includes a control system configured with interlocking control logic for use during the transfer of the antenna base between the antenna erection mechanism and the automatic antenna connection mechanism: When the antenna base moves from the antenna erection mechanism to the antenna automatic connection mechanism, the locking pin of the antenna erection mechanism can only be released after the locking pin of the antenna automatic connection mechanism has been locked; and when the antenna base moves from the antenna automatic connection mechanism to the antenna erection mechanism, the locking pin of the antenna automatic connection mechanism can only be released after the locking pin of the antenna erection mechanism has been locked.
[0022] Furthermore, the control system determines whether the locking or unlocking state is in place by reading the position feedback signal or limit switch signal on the antenna erection mechanism and the antenna automatic connection mechanism, so as to trigger the program interlock logic.
[0023] Furthermore, the automatic antenna connection mechanism and the antenna base are configured to perform a three-level progressive docking logic, specifically including: First-stage preliminary alignment: The alignment guide shaft at the center of the antenna connecting plate is first inserted into the guide shaft hole at the center of the docking base plate to establish preliminary coaxial guidance between the antenna base and the gimbal; Second-level positioning: Under the guidance of the alignment guide shaft, multiple connecting shafts distributed around the alignment guide shaft are respectively inserted into the corresponding connecting shaft holes to restrict the rotational freedom of the antenna base relative to the docking base plate and achieve precise positioning; Third-level locking: After each of the connecting shafts is inserted into place, the electric pin extends and passes into the pin hole of the connecting shaft, thereby achieving axial locking between the antenna base and the automatic antenna connection mechanism.
[0024] Compared with the prior art, the present invention has the following advantages.
[0025] This invention enables communication equipment antennas to be quickly and automatically transferred and locked at the top of 4-meter and 13.5-meter electric lifting poles, and to automatically raise and align the antennas, thereby ensuring the communication quality and communication distance of the communication equipment. Furthermore, by measures such as lowering the 13.5-meter electric lifting pole and automatically transferring the antenna, the height restriction requirements of communication vehicles are met to the greatest extent.
[0026] This invention features automatic raising and lowering, automatic antenna deployment, storage and pre-alignment, and automatic feeder cable deployment and retraction. It enables fully automated antenna erection, alignment, and dismantling, boasting a high degree of automation and ease of operation, significantly improving troop combat effectiveness. It is an important supporting product for communication equipment. Its control system coordinates the logical control between various actions to achieve the transfer of the antenna on the lifting frame and main lifting mast, completing the erection and dismantling process.

[0037] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.
[0038] The terminology used in the embodiments of this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The singular forms “a,” “the,” and “the” as used in the embodiments of this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.
[0039] Depending on the context, words such as “if” or “suppose” used here can be interpreted as “when”, “in response to determination”, or “in response to detection”.
[0040] For ease of understanding, the embodiments of this disclosure will be described in detail first.
[0041] like Figure 1-8 As shown, this embodiment provides an antenna lifting platform, including a platform mounting base plate 1, a main lifting rod 2, a pair of lifting frames 3, an antenna erection mechanism 4, a gimbal 5, an automatic antenna connection mechanism 6, a control box 7, and an antenna base 8. Each module is integrated into one unit through connecting cables, auxiliary support structures, and accessories.
[0042] The platform mounting base plate 1 serves as the basic support structure for the entire lifting platform. The main lifting rod 2 is rotatably connected to the mounting seat 205 fixed on the platform mounting base plate 1 via a pivot 206 at its bottom. The main lifting rod 2 consists of multiple nested and retractable main rod sleeves 212, used to lift the gimbal 5 and antenna equipment to the working height.
[0043] A pair of lifting frames 3 are symmetrically arranged on both sides of the main lifting mast 2, and an antenna erection mechanism 4 is installed on top of each frame. A gimbal 5 is connected to the top of the main lifting mast 2 via a mounting shaft and can rotate around the central axis of the main lifting mast 2 to adjust the antenna's azimuth during operation. An automatic antenna connection mechanism 6 is fixed to the top of the gimbal 5 and is used for automatic docking, locking, or detachment from the antenna base 8. A control box 7 is located on the platform mounting base 1 and is used to control the erection / retraction process of the platform, and to display the status of each action and operating parameters.
[0044] Detailed descriptions of each component: Lifting frame 3: When in the retraction state, it serves as a support for the antenna equipment in the driving state; during the erection process, it is used to lift the antenna lifting equipment to the docking height to complete the erection and retraction of the antenna equipment.
[0045] Electric push rod 202: Its cylinder bottom is hinged to push rod mounting seat 201 fixed on the platform mounting base plate 1, and its extended end is hinged to the connecting lug seat in the middle of the outer sleeve of the main lifting rod 2. By adjusting the extension length of the electric push rod 202, the main lifting rod 2 can be driven to complete the uprighting or lowering action around the rotating shaft 206. When the main lifting rod 2 is in the upright state, the electric push rod 202 also plays an auxiliary support role.
[0046] Antenna erection mechanism 4: mainly responsible for erecting the antenna equipment during installation and laying down and locking the antenna equipment during dismantling.
[0047] Main lifting mast 2: Used to lift the gimbal 5 and antenna equipment to the predetermined working height.
[0048] Gimbal 5: It has the ability to rotate around the central axis of the main lifting mast 2, and is used to adjust the azimuth angle of the antenna.
[0049] Example 1: The gimbal 5 includes a housing, a mounting shaft, and a reduction gear mechanism and a drive motor housed within the housing. The mounting shaft is fixedly connected to the top of the main lifting rod 2. The drive motor drives the housing to rotate around the mounting shaft via the reduction gear mechanism, thereby adjusting the angle of the antenna equipment relative to the axis of the main lifting rod 2. It is understood that the specific implementation of this gimbal is not the key to this design; any existing mechanism capable of azimuth rotation can be applied here. This is existing technology and will not be elaborated upon here.
[0050] Antenna automatic connection mechanism 6: Fixed to the top of the gimbal 5, it automatically completes docking, locking or unlocking with the antenna base 8 during the erection or dismantling process.
[0051] Control Box 7: Integrates power supply and control circuitry to coordinate the sequence of actions of each actuator and to monitor and display the system status in real time.
[0052] Connecting cables: used to connect the power supply and control signals between the control box 7 and each functional module.
[0053] Regarding the preferred embodiment and the structure of the lifting frame 3 and the main lifting rod 2, it should be noted that the multi-stage screw-sleeve synchronous telescopic drive structure used in the lifting frame 3 and the multi-stage screw-sleeve segment-by-segment telescopic drive structure used in the main lifting rod 2 can be implemented using existing technologies. For example, the lifting mechanism scheme disclosed in patent CN219507559U can be referred to. The innovation of this invention lies in the technical coordination of such lifting mechanisms with antenna erection, automatic docking, and other mechanisms, rather than an improvement to the lifting drive structure itself. Therefore, only two embodiments are provided for illustration: In one specific embodiment of the lifting frame, the lifting frame 3 consists of two identical lifting frame sleeves on the left and right sides. Each lifting frame sleeve adopts a multi-stage nested screw-sleeve synchronous telescopic structure, specifically including three layers of lifting frame screws 307 and three layers of lifting frame sleeves 308. The screws 307 of each layer achieve synchronous rotation through a rotation-limiting lifting guide key. Each screw is fitted with a lifting frame nut 306, and each nut is fixedly connected to the lower end of the corresponding layer's lifting frame sleeve 308 through a nut seat. Rotation-limiting lifting guide blocks are provided between adjacent sleeves to ensure that each sleeve can only move relative to the other along the axial direction and cannot rotate. The lifting frame motor 304 drives the transmission shaft 309 through the lifting frame reduction device 305, thereby synchronously driving the extension and retraction of the two lifting frame sleeves, avoiding the asynchronous lifting problems that may be caused by dual-motor drive.
[0054] In one specific embodiment of the main lifting rod, the bottom of the main lifting rod 2 is rotatably connected to the mounting base 205 via a rotating shaft 206. A connecting lug is provided in the middle of its outer sleeve, hinged to the extended end of the electric push rod 202. The bottom of the cylinder of the electric push rod 202 is hinged to the push rod mounting base 201, which is fixed to the platform mounting base plate 1, forming a stable triangular support structure. The main lifting rod 2 adopts a multi-section (seven-stage) screw-sleeve segment-by-segment telescopic structure, including seven layers of main rod screws 211 and seven layers of main rod sleeves 212. Each layer of main rod screws 211 rotates synchronously via a rotation-limiting lifting guide key. Each screw is equipped with a main rod nut 210, and each nut is fixedly connected to the lower end of the corresponding main rod sleeve 212 via a nut seat. A rotation-limiting lifting guide block is provided between adjacent sleeves to restrict the degree of rotational freedom, allowing only axial extension and retraction. The main pole motor 208 drives the main pole lead screw 211 to rotate via the main pole reduction gear 209, thereby causing the main pole sleeves 212 at each stage to extend and retract section by section. The lifting stroke is controlled by the stroke controller inside the main pole reduction gear 209, and it automatically stops when it reaches the desired position. When the main lifting pole 2 collapses, its body rests on the main lifting pole bracket 213, forming a mechanical limit; if the drive continues at this time, the motor will trigger the protection shutdown due to overload.
[0055] In addition, the mounting base 205 is equipped with a vertical limit switch 204, which is used to detect whether the main lifting rod 2 has reached the set angle of vertical or horizontal movement, and control the electric push rod 202 to stop moving accordingly.
[0056] In one specific embodiment, after the main lifting rod 2 reaches the vertical position, the electric locking pin 203 extends to lock the posture of the main lifting rod 2.
[0057] The preferred embodiment, the antenna erection mechanism 4, includes an erection motor 401, an antenna bracket 402, an electric locking pin 403, and a limit switch. The erection motor 401 is mounted on the top of one of the lifting frames 3, and its output shaft is fixedly connected to the rotation shaft at one end of the antenna bracket 402 via its own worm gear reducer. The antenna bracket 402 is supported at both ends by bearing seats on the top of the two lifting frames 3, and can be rotated within the range of 0° to 90° under the drive of the erection motor 401.
[0058] Example 2: The worm gear reducer has a self-locking characteristic, which allows the antenna bracket 402 to remain stable in any flipping position. A limit switch is installed on the bracket mounting base to detect whether the antenna bracket 402 has reached its vertical or horizontal limit position and automatically stops the motor.
[0059] The antenna bracket 402 has an electric locking groove 404 in the middle, which cooperates with the lug on the antenna base 8. When the two are aligned, the electric locking pin 403 is inserted into the concentric hole, thereby locking the antenna erection mechanism 4 and the antenna base 8.
[0060] In the preferred embodiment, the automatic antenna connection mechanism 6 includes a docking base plate 603 fixed to the top of the gimbal 5. The upper surface of the docking base plate 603 has a guide shaft hole 602 at its center, and multiple connecting shaft holes 601 are evenly distributed around it. An electric latch 604 is installed on the lower surface of the docking base plate 603, corresponding to each connecting shaft hole 601. An antenna connecting plate 803 is fixed to the corresponding antenna base 8, which has a connecting shaft 801 corresponding to the connecting shaft hole 601, and an alignment guide shaft 802 located at its center. During docking, the alignment guide shaft 802 first inserts into the guide shaft hole 602 to complete initial alignment, and then the connecting shaft 801 inserts into the connecting shaft hole 601. After reaching the desired position, the electric latch 604 extends and passes into the pin hole of the connecting shaft 801, achieving reliable locking between the antenna base 8 and the automatic antenna connection mechanism 6.
[0061] Example 3: To prevent equipment damage or antenna detachment due to misoperation, the system is equipped with program interlocking logic: During the automatic antenna connection mechanism 6, or the reverse transfer process, when the antenna base is transferred from the lifting frame 3 to the main lifting rod 2, it must be ensured that one of the locking mechanisms (antenna erection mechanism 4 or automatic antenna connection mechanism 6) is completed before the locking pin at the other location can be released. Furthermore, only after both steps are completed can subsequent lifting actions of the main lifting rod 2 or the lifting frame 3 be performed.
[0062] The operation of the antenna lifting platform specifically includes two processes: erection and dismantling. I. Setup process.
[0063] 1. In the initial state, the antenna is in a horizontal inverted state, and its bottom antenna base 8 is locked on the antenna inverted mechanism 4 on the top of the two side lifting frames 3; the main lifting rod 2 is inverted on the main lifting rod bracket 213 on the platform mounting base plate 1.
[0064] 2. Start the control box 7. The lifting frame 3 rises synchronously under the drive of the lifting frame motor 304, raising the antenna to the preset docking height. Then the electric push rod 202 extends, pushing the main lifting rod 2 to rotate upward around the rotating shaft 206 to the vertical position; 3. The inverting motor 401 in the antenna inverting mechanism 4 starts, and drives the antenna bracket 402 to rotate 90° through the worm gear reducer, so that the antenna changes from a horizontal state to a vertical state.
[0065] 4. Align the antenna automatic connection mechanism 6 on the gimbal 5 with the antenna base 8: First, the alignment guide shaft 802 is inserted into the guide shaft hole 602 to complete the coarse positioning, and then the connecting shaft 801 enters the connecting shaft hole 601; after it is in place, the electric pin 604 automatically extends and locks into the pin hole of the connecting shaft 801 to achieve a reliable connection.
[0066] 5. After confirming that the antenna automatic connection mechanism 6 is locked, the electric locking pin 403 of the antenna inverting mechanism 4 is unlocked, and the lifting frame 3 descends and resets.
[0067] 6. The main lifting mast 2 continues to extend under the drive of the main mast motor 208, raising the antenna to the working height; the gimbal 5 can rotate as needed to adjust the antenna azimuth angle and enter the normal working state.
[0068] II. Withdrawal Process.
[0069] 1. The control box 7 issues a retraction command, and the main lifting mast 2 descends, bringing the antenna back to the docking height.
[0070] 2. The lifting frame 3 rises synchronously to the docking position, and the antenna bracket 402 of the antenna erection mechanism 4 remains vertical and is aligned with the antenna base 8.
[0071] 3. The electric locking pin 403 of the antenna erection mechanism 4 first extends and inserts into the ear hole of the antenna base 8 to complete the initial locking of the antenna base 8, ensuring that the antenna base 8 is in a locked state at the beginning of the transfer.
[0072] 4. After confirming that the antenna inverting mechanism 4 has been locked, the electric pin 604 of the antenna automatic connection mechanism 6 retracts, releasing its connection with the antenna base 8; then the inverting motor 401 runs in reverse, driving the antenna bracket 402 and the antenna base 8 to slowly flip from the vertical position to the horizontal position.
[0073] 5. Under the action of the electric push rod 202, the main lifting rod 2 falls backward and lands on the main lifting rod bracket 213; the lifting frame 3 descends to the lowest position simultaneously.
[0074] The system has entered the transportation phase; the overall structure is compact and it can be moved safely.
[0075] The entire working process is coordinated by the control box 7. Each actuator can be equipped with travel limit switches and interlock logic to ensure correct action sequence, reliable connection, and safe operation.

The antenna lifting platform according to claim 7, characterized in that: The automatic antenna connection mechanism (6) and the antenna base (8) are configured to perform a three-level progressive docking logic, specifically including: First-stage preliminary alignment: The alignment guide shaft (802) at the center of the antenna connecting plate (803) is first inserted into the guide shaft hole (602) at the center of the docking base plate (603) to establish preliminary coaxial guidance between the antenna base (8) and the gimbal (5); Second-level positioning: Under the guidance of the alignment guide shaft (802), a plurality of connecting shafts (801) distributed around the alignment guide shaft (802) are respectively inserted into the corresponding connecting shaft holes (601) to restrict the rotational freedom of the antenna base (8) relative to the docking base plate (603) and achieve precise positioning. Third-level locking: After each of the connecting shafts (801) is inserted into place, the electric pin (604) extends out and passes into the pin hole of the connecting shaft (801) to achieve axial locking between the antenna base (8) and the antenna automatic connection mechanism (6).
