Description

Technical Field

[0001] This utility model relates to the field of trailer technology, specifically to a radio frequency antenna turnover trailer. Background Technology

[0002] As a core component in modern wireless communication, radar detection, electronic countermeasures, and satellite navigation systems, the performance of radio frequency antennas directly affects the effective range, signal quality, and transmission reliability of the entire system. In practical applications, such precision equipment often needs to be moved between different locations, such as during field surveys, temporary site construction, military deployments, or equipment maintenance and repair. According to publication number CN214524112U, a semi-trailer device for carrying antennas is disclosed. This technology discloses a technical solution that includes "a front section for mounting the antenna, a rear section configured to form a transport vehicle with the front section, and a docking device disposed between the rear section and the front section. By designing the front section, the rear section, and the docking device, the antenna is carried by the front section and the rear section, and the height of the antenna is adjusted by the docking device, thus improving the transport performance of the antenna." Existing methods for fixing antennas to trailers often rely on a single lateral clamping or vertical pressing, which makes it difficult to form a stable force system in dynamic transportation environments. This can lead to the antenna slipping, warping, or even detaching from the fixing surface when subjected to inertial forces or impacts from different directions, thus posing a risk of insecure fixing. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a radio frequency antenna transport trailer. By using horizontal lateral clamping of the clamping components and vertical top pressing of the locking components, a constraint is formed on the radio frequency antenna base, improving the stability and safety of the radio frequency antenna during transportation and preventing shaking, displacement, or jumping due to bumps.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a radio frequency antenna transport trailer, comprising a trailer frame, wherein a fixing mechanism is provided on the trailer frame for fixing the radio frequency antenna, the fixing mechanism comprising: The clamping assembly includes a base plate fixed inside the upper part of the trailer frame. Slide plates are slidably installed through both the left and right ends of the trailer frame. A connecting frame is fixed to the top of the outer end of the slide plate. A clamping plate is fixed to the inner side of the upper end of the connecting frame and is located above the base plate. A threaded rod is threadedly installed at the front end of the trailer frame. A handwheel is fixed to the front end of the threaded rod. A connecting plate is rotatably installed at the rear end of the threaded rod. Connecting rods are pivotally connected to both the left and right sides inside the connecting plate, and the connecting rods are pivotally connected to the bottom of the slide plate. A locking assembly is provided on the clamping assembly and is used to press the radio frequency antenna fixed on the clamping assembly.

[0005] Preferably, the locking assembly includes a bearing fixed to the top of the connecting frame, a shaft bracket rotatably mounted between the two ends inside the bearing, a pressure plate mounted on the shaft bracket, a support arm fixed to the end of the shaft bracket, a sliding groove opened inside the support arm, an electric push rod mounted on the top of the connecting frame, a connector fixed to the output end of the electric push rod, and a roller rotatably mounted inside the connector and located inside the sliding groove.

[0006] Preferably, the locking assembly further includes a guide rail fixed to the top of the connecting frame, a slider slidably mounted on the guide rail, and a connector fixed to the top of the slider.

[0007] Preferably, the locking assembly further includes a pad fixed to the inner wall of the pressure plate, and the pad is made of polyurethane.

[0008] Preferably, the shaft frame has mounting holes, and the pressure plate is fixed to the shaft frame by bolts through the mounting holes.

[0009] Preferably, the clamping assembly further includes two guide seats fixed at the left and right ends of the substrate, with a guide rod slidably installed inside the guide seats and fixed to the clamping plate.

[0010] Beneficial effects This invention provides a radio frequency antenna turnover trailer. Compared with the prior art, it has the following advantages: 1. After the RF antenna is transported onto the substrate, the screw rod is rotated by turning the handwheel, which in turn pushes the connecting plate to move backward. The connecting rods on both sides drive the left and right slide plates to slide towards each other, so that the clamping plate fixed on the slide plate clamps the RF antenna base placed on the substrate from the horizontal direction, realizing the rapid centering and firm lateral fixation of the RF antenna.

[0011] 2. After the clamping assembly completes the initial lateral positioning of the RF antenna, the output end of the electric push rod drives the roller on the connector to move linearly. The roller rolls in the groove opened inside the support arm and applies a thrust. Since the support arm is fixedly connected to the shaft frame and the shaft frame is rotatably mounted on the shaft seat, this thrust is converted into a torque that forces the support arm and the shaft frame to rotate around the shaft seat. This torque drives the shaft frame to rotate downward, which in turn drives the pressure plate fixed on it to swing downward, so that the pressure plate presses tightly against the upper surface of the RF antenna base. The horizontal lateral clamping of the clamping assembly and the vertical top pressing of the locking assembly form a constraint on the RF antenna base, improving the stability and safety of the RF antenna during transportation and preventing shaking, displacement or jumping caused by bumps.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a radio frequency antenna turnover trailer, including a trailer frame 1, on which a fixing mechanism 2 is provided for fixing the radio frequency antenna, the fixing mechanism 2 including: The clamping assembly 21 includes a base plate 211 fixed inside the upper part of the trailer frame 1. Slide plates 212 are slidably installed through both the left and right ends of the trailer frame 1. A connecting frame 213 is fixed to the top of the outer end of the slide plate 212. A clamping plate 214 is fixed to the inner side of the upper end of the connecting frame 213 and is located above the base plate 211. A threaded rod 215 is threadedly installed at the front end of the trailer frame 1. A handwheel 216 is fixed to the front end of the threaded rod 215. A connecting plate 217 is rotatably installed at the rear end of the threaded rod 215. Connecting rods 218 are pivotally connected to the left and right sides of the connecting plate 217, and the connecting rods 218 are pivotally connected to the bottom of the slide plate 212. The locking component 22 is disposed on the clamping component 21 and is used to press the radio frequency antenna fixed on the clamping component 21.

[0016] In this embodiment, after the radio frequency antenna is transported onto the substrate 211, the threaded rod 215 is rotated by turning the handwheel 216, which in turn pushes the connecting plate 217 to move backward. The connecting rods 218 on both sides drive the left and right sliding plates 212 to slide towards each other, thereby causing the clamping plate 214 fixed on the sliding plate 212 to clamp the radio frequency antenna base placed on the substrate 211 from the horizontal direction, thus achieving rapid centering and firm lateral fixation of the radio frequency antenna.

[0017] Specifically, the locking assembly 22 includes a bearing seat 221 fixed to the top of the connecting frame 213, a shaft bracket 222 rotatably mounted between the two ends inside the bearing seat 221, a pressure plate 223 mounted on the shaft bracket 222, a support arm 224 fixed to the end of the shaft bracket 222, a slide groove 225 opened inside the support arm 224, an electric push rod 226 mounted on the top of the connecting frame 213, a connector 227 fixed to the output end of the electric push rod 226, and a roller 228 rotatably mounted inside the connector 227 and located inside the slide groove 225.

[0018] In this embodiment, after the clamping assembly 21 completes the initial lateral positioning of the RF antenna, the output end of the electric push rod 226 drives the roller 228 on the connector 227 to move linearly. The roller 228 rolls in the groove 225 inside the support arm 224 and applies a thrust. Since the support arm 224 is fixedly connected to the shaft frame 222 and the shaft frame 222 is rotatably mounted on the shaft seat 221, this thrust is converted into a torque that forces the support arm 224 and the shaft frame 222 to rotate around the shaft seat 221. This torque drives the shaft frame 222 to rotate downward, thereby causing the pressure plate 223 fixed on it to swing downward, so that the pressure plate 223 presses tightly against the upper surface of the RF antenna base. The horizontal lateral clamping of the clamping assembly 21 and the vertical top pressing of the locking assembly 22 form a constraint on the RF antenna base, improving the stability and safety of the RF antenna during transportation and preventing shaking, displacement or jumping caused by bumps.

[0019] Specifically, the locking assembly 22 also includes a guide rail 229 fixed to the top of the connecting bracket 213, a slider 2210 slidably mounted on the guide rail 229, and a connector 227 fixed to the top of the slider 2210.

[0020] In this embodiment, the guide rail 229 and the slider 2210 cooperate to provide linear guidance for the movement of the connector 227, avoiding efficiency loss and component wear caused by movement jamming or offset.

[0021] Specifically, the locking assembly 22 also includes a pad 2211 fixed to the inner wall of the pressure plate 223, and the pad 2211 is made of polyurethane.

[0022] In this embodiment, when the pressure plate 223 presses against the surface of the antenna base, the polyurethane pad makes flexible contact with the surface of the antenna base, effectively absorbing and isolating the high-frequency vibration and instantaneous impact generated by the trailer during its movement.

[0023] Specifically, the shaft bracket 222 has mounting holes, and the pressure plate 223 is fixed to the shaft bracket 222 by bolts through the mounting holes.

[0024] In this embodiment, when it is necessary to transfer radio frequency antennas of different models or sizes, the current pressure plate 223 can be quickly removed and replaced with a special pressure plate that is more suitable in terms of length, shape or contact area.

[0025] Specifically, the clamping assembly 21 also includes two guide seats 219 fixed at the left and right ends of the substrate 211. A guide rod 2110 is slidably installed inside the guide seat 219 and fixed to the clamping plate 214.

[0026] In this embodiment, when the clamping plate 214 on the slide plate 212 slides laterally under the drive of the connecting rod 218, it is restricted in the channel of the guide seat 219 by the guide rod 2110, and can only move in a straight line, so as to prevent the clamping plate 214 from tilting, shaking or even jamming due to uneven force during the movement.

[0027] The working principle and usage process of this utility model are as follows: First, after the radio frequency antenna is transported to the substrate 211, the threaded rod 215 is driven to rotate by rotating the handwheel 216, which in turn pushes the connecting plate 217 to move backward. The connecting rods 218 on both sides drive the left and right sliding plates 212 to slide towards each other, so that the clamping plate 214 fixed on the sliding plate 212 clamps the radio frequency antenna base placed on the substrate 211 from the horizontal direction, thereby realizing the rapid centering and firm lateral fixation of the radio frequency antenna. Then, the output end of the electric push rod 226 drives the roller 228 on the connector 227 to move linearly. The roller 228 rolls in the groove 225 inside the support arm 224 and applies a thrust. Since the support arm 224 is fixedly connected to the shaft frame 222 and the shaft frame 222 is rotatably mounted on the shaft seat 221, this thrust is converted into a torque that forces the support arm 224 and the shaft frame 222 to rotate around the shaft seat 221. This torque drives the shaft frame 222 to rotate downward, which in turn drives the pressure plate 223 fixed on it to swing downward, so that the pressure plate 223 presses tightly against the upper surface of the RF antenna base. The horizontal lateral clamping of the clamping assembly 21 and the vertical top pressing of the locking assembly 22 form a constraint on the RF antenna base, improving the stability and safety of the RF antenna during transportation and preventing shaking, displacement or jumping caused by bumps.
