The device does not protrude outside the ship body when the ship body is moving or docking, avoiding safety hazards and providing good protection for the device. However, when the device bears the LNG hose, it does not limit the LNG hose, which can easily cause the LNG hose to detach from the bearing device, resulting in wear of the LNG hose. Therefore, a marine LNG hose bearing device is proposed to solve the above problems. UTILITY MODEL CONTENT

[0004] To overcome the shortcomings of the prior art, the utility model provides a marine LNG hose bearing device, which has the advantages of limiting the LNG hose and solving the problem of the prior art that the LNG hose is not limited and easily detaches from the bearing device, causing wear of the LNG hose.

[0006] Further, the fixing mechanism comprises a U-shaped block, a fixing bolt, and a fixing nut, the outer peripheral wall of the first annular clamp plate and the second annular clamp plate is fixedly installed with a U-shaped block, the inside of the U-shaped block is rotatably installed with a fixing bolt extending to the top of the upper U-shaped block, and the outer peripheral wall top end of the fixing bolt is threadedly connected with a fixing nut.

[0007] Further, the inner peripheral wall of the first annular clamp plate and the second annular clamp plate is provided with a roller, the outer peripheral wall back surface of the first annular clamp plate and the second annular clamp plate is provided with a hinge, and the first annular clamp plate and the second annular clamp plate are rotatably connected through the hinge.

[0008] Furthermore, the driving mechanism includes a sliding rod, a sliding block, and a hydraulic push rod. The sliding rod is fixedly installed at both the front and rear ends of the U-shaped base. A sliding block with one end fixedly connected to the bottom of the top plate is slidably sleeved on the outer peripheral wall of the sliding rod. A hydraulic push rod is embedded on the right side of the U-shaped base, and the output end of the hydraulic push rod is fixedly connected to the sliding block.

[0009] Furthermore, the limiting mechanism includes an electric push rod, a limiting sleeve, a positioning block, and a U-shaped sleeve. The electric push rod is fixedly installed on both the front and back of the U-shaped base. Two limiting sleeves are fixedly installed on both the front and back of the top plate. U-shaped sleeves are fixedly installed on both the front and back of the U-shaped base and above the electric push rod. A positioning block with one end penetrating through the U-shaped sleeve and extending into the limiting sleeve is fixedly installed at the output end of the electric push rod.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] 1. This marine LNG hose support device, through its fixed mechanism, allows the second annular clamp to be flipped over and fastened to the outside of the LNG hose when the LNG hose is placed inside the first annular clamp for support. The fixing bolts are then flipped over so that their top ends are inserted into the upper U-shaped block, and the fixing nuts are tightened to limit the LNG hose and prevent it from running out of the first annular clamp. This solves the problem of existing support devices not limiting the LNG hose, which can easily cause the LNG hose to detach from the support device and thus cause wear on the LNG hose.

[0014] 2. The LNG hose support device for ships, through the setting of the limiting mechanism, operates the electric push rod to drive the positioning block into the middle limiting sleeve. In this way, the position of the top plate can be fixed, so that when the top plate and the supporting part extend out, the device is more stable and improves the practicality of the device.
