TECHNICAL FIELD

[0001] The application relates to the technical field of radar masts, in particular to a hydraulic tiltable radar mast. BACKGROUND

[0002] A dredger is a ship used for underwater engineering, such as dredging waterways, maintaining ports and blowing sand to fill the sea. The ship completes the task by excavating, pumping or blowing sand. The radar mast on the ship is a support structure for installing radar antennas, communication equipment and other sensors, usually located at the highest point of the ship to ensure that the equipment has a good view and signal coverage, while reducing the interference of the ship structure on electromagnetic waves.

[0003] The prior art does not have a structure for lowering the height of the radar mast by tilting, so that the existing dredger adopts a hard connection mode to ensure stability during use. However, due to the need for dredging tasks in inland waterways, the high mast causes the dredger to be unable to normally pass to the designated location due to the height limit of the bridge in the inland waterway, and manual disassembly and assembly of the mast are too cumbersome. Based on the existing technical deficiencies, the application designs a hydraulic tiltable radar mast. SUMMARY

[0004] The application provides a hydraulic tiltable radar mast, which has the advantage of lowering the height of the radar mast by tilting.

[0005] The application provides the following technical scheme: a hydraulic tiltable radar mast, comprising a lower platform, an upper platform arranged above the lower platform, and a tilting mechanism arranged between the lower platform and the upper platform and facilitating tilting and lowering of the upper platform and the radar. The tilting mechanism comprises a support, a rotating frame, a rotating rod, a mast body, a balance block, a positioning ring, a hinge joint, a hinge seat and an extension cylinder, the support is fixedly connected to the upper surface of the lower platform, the rotating frame is fixedly connected to the top of the support, the rotating rod is rotatably connected in the rotating frame, the mast body is fixedly connected to the rotating rod, the balance block is fixedly connected to the bottom end of the mast body, the positioning ring is fixedly connected to the side wall of the mast body, the hinge joint is fixedly connected to the side wall of the positioning ring, the hinge seat is fixedly connected to the upper surface of the lower platform, and the extension cylinder is rotatably connected at both ends to the hinge joint and the hinge seat.

[0007] As a preferred technical scheme of the present application, the side wall of the upper platform is fixedly connected with a platform extension frame, the upper surface of the upper platform is fixedly connected with an upper guardrail, the upper surface of the upper platform is fixedly connected with a fixed support, the top end of the fixed support is fixedly connected with a radar antenna main body, the side wall of the fixed support is fixedly connected with a lightning rod, the lower surface of the upper platform is fixedly connected with a cage ladder, and the upper surface of the upper platform is provided with a cover-containing operation opening.

[0008] As a preferred technical scheme of the present application, the mast main body is rotatably connected between the support and the rotating frame, and the top end of the mast main body is fixedly connected to the lower surface of the upper platform.

[0009] As a preferred technical scheme of the present application, the hinge joint is fixedly connected to the side wall of the mast main body through a positioning ring, and the telescopic cylinder is supported on one side of the mast main body through the hinge joint.

[0010] As a preferred technical scheme of the present application, the cage ladder is fixedly connected to the side wall of the mast main body.

[0014] As a preferred technical scheme of the present application, the mast main body and the balance block are movably arranged in the movable opening.

[0015] Compared with the prior art, the present application has the following beneficial effects: This hydraulic tilting radar mast is controlled via a telescopic cylinder on the control panel in the bridge. The cylinder retracts, pulling the hinge joint downwards under the limit of the hinge seat. The downward-moving hinge joint, through a positioning ring, pulls the mast body to rotate under the support of the rotating rod, swivel frame, and support. During the rotation of the mast body, the upper platform and other components at the top rotate and descend in height until the radar antenna and lightning rod reach a passable height. Then, the telescopic cylinder extends, pushing the mast body in the opposite direction under the support of the hinge seat, swivel frame, and rotating rod. This pushes the mast body back to a vertical position, restoring the upper platform and other components to their original angle and height. This device facilitates tilting the mast body, allowing ships to pass smoothly. Attached Figure Description

By setting up support 301, rotating frame 302 and rotating rod 303, the upper platform 2 can be rotated and tilted to lower its height, so that the ship can pass smoothly under the lower area. By setting up positioning ring 306, hinge joint 307, hinge seat 308 and telescopic cylinder 309, the tilting or vertical reset of the mast body 304 and the upper platform 2 can be controlled. By setting up balance block 305, the stability of the mast body 304 can be maintained when moving or in use.

[0022] Please see Figure 5 - Figure 7 The upper platform 2 is fixedly connected to the side wall of the upper platform 2, the upper guardrail 202 is fixedly connected to the upper surface of the upper platform 2, the upper surface of the upper platform 2 is fixedly connected to the fixed bracket 203, the top of the fixed bracket 203 is fixedly connected to the radar antenna body 204, the side wall of the fixed bracket 203 is fixedly connected to the lightning rod 205, the lower surface of the upper platform 2 is fixedly connected to the cage ladder 206, the upper surface of the upper platform 2 is provided with a covered working opening 207, the cage ladder 206 is fixedly connected to the side wall of the mast body 304, and the covered working opening 207 is opened directly above the cage ladder 206.

[0023] By setting up a fixed bracket 203 and a radar antenna body 204, it is possible to facilitate navigation and positioning of the vessel. By setting up a lightning rod 205, it is possible to prevent lightning from directly striking the radar antenna body 204 during thunderstorms and causing damage. By setting up a cage ladder 206 and a covered access port 207, it is possible to enable personnel to climb onto the upper platform 2 to inspect and maintain the radar antenna body 204.

[0024] Working principle: When a hydraulic tilting radar mast is used, in the initial state, the platform support 104 and the reinforcing column 105 are first set on the lower surface of the lower platform 1. The top of the side support 110 set on one side of the platform support 104 is connected to the lower platform 1. At the same time, the navigation radar 103 is set on the upper surface of the lower platform 1. The upper platform 2, the fixed bracket 203 and the radar antenna body 204 are also set above the lower platform 1 through the tilting mechanism 3, so as to use radar to detect the information required for navigation during ship navigation. The tilting mechanism 3 is set between the upper platform 2 and the lower platform 1, so that the upper platform 2, the radar antenna body 204 and the support 301 can be tilted and lowered in the lower area to lower the highest point of the ship so that the ship can pass smoothly. When it is necessary to tilt the mast body 304 to allow the ship to pass smoothly, the telescopic cylinder 309 is first controlled on the control panel in the wheelhouse. The telescopic cylinder 309 retracts under the limit of the hinge seat 308, pulling the hinge joint 307 downward. The downward-moving hinge joint 307 pulls the mast body 304 to rotate under the support of the rotating roller 303, the rotating frame 302, and the support 301 through the positioning ring 306. During the rotation of the mast body 304, the upper platform 2 at the top and other components rotate and descend in height until the highest position of the radar antenna body 204 and the lightning rod 205 is lowered to a passable height. Then, the telescopic cylinder 309 is controlled to extend. Under the support of the hinge seat 308, the telescopic cylinder 309 pushes the mast body 304 to rotate in the opposite direction under the support of the support 301, the rotating frame 302, and the rotating roller 303. This pushes the mast body 304 to maintain a vertical state and restores the upper platform 2 and other components above it to their original angle and height. This device facilitates the tilting of the mast body 304 to allow the ship to pass smoothly.
