Natural gas, as a clean, economical, safe, and efficient energy source, is highly favored by various countries and energy industries. Against this backdrop, the importance of liquefied natural gas (LNG) transportation and storage equipment is self-evident. The Mark III membrane containment system is a new type of LNG cargo containment system developed by the French company GTT. It holds approximately 90% of the market share in large LNG carriers. The cargo hold is fully covered with MARK III corrugated sheets. Therefore, the installation of the corrugated sheets on the top surface is very difficult during construction, and how to install the corrugated sheets smoothly and stably has become a major challenge.

[0003] Currently, the installation of corrugated sheets on the top surface is carried out using a lift or robot in conjunction with fixed fixtures. However, since the scaffolding is nearly 3.5 meters high, the existing lifts or robots are large in size, heavy in weight, expensive, and have high maintenance costs. They are also inconvenient to transport and store, have long operating strokes, and are prone to vibration. Furthermore, the installation accuracy of the corrugated sheets is difficult to control. Therefore, a new fixed fixture for installing corrugated sheets on the top surface of LNG fuel ships is designed to solve the problems of the large size and heavy weight of the fixed fixture and the inconvenience of transportation during the installation of corrugated sheets on the top surface.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Please see Figure 1-3 The present invention provides a technical solution: a mounting fixture for the top surface of a corrugated plate for LNG fuel ships, including a bracket 1. The bracket 1 includes four vertical square tubes 101. Both the upper and lower ends of the vertical square tubes 101 are threaded with horizontal square tubes 102. One side of the upper horizontal square tube 102 is threaded with a circular support plate 103. The bracket 1 itself has a certain height, which is conducive to reducing the lifting stroke, thereby making the lifting operation more stable.

[0022] A long lead screw 2 is inserted through the middle of the vertical square tube 101. The long lead screw 2 is inserted through the center of the circular support plate 103. The long lead screw 2 is connected to the worm gear 3. The connection between the long lead screw 2 and the worm gear 3 facilitates the lifting and lowering of the long lead screw 2.

[0023] The worm gear disk 3 and the worm gear rod 4 are adapted to form a worm gear mechanism. One end of the worm gear rod 4 is coaxially welded with shaft 5, and the other end of shaft 5 is threadedly connected to parasol wheel 6. Parasol wheel 7 is meshed with one side of parasol wheel 6. The threaded connection between shaft 5 and parasol wheel 6 facilitates the disassembly and assembly of parts. Shaft 8 is inserted through the middle of parasol wheel 7, and motor 9 is connected to one side of shaft 8.

[0024] Several balls 104 are fitted and connected above the circular support disk 103. The balls 104 are located below the worm gear disk 3. The balls 104 help to convert sliding friction into rolling friction, thereby facilitating the rotation of the worm gear disk 3.

[0025] A universal clamp 201 is fixedly installed above the long lead screw 2. The universal clamp 201 is beneficial for clamping and fixing the corrugated plate.

[0026] A motor frame 10 is provided below the motor 9, and the motor frame 10 is threadedly connected to the horizontal square tube 102.

[0027] A support rod 11 is welded to the top of the motor frame 10. A ball bearing 13 is fitted and connected to the top of the support rod 11. The ball bearing 13 is located below the parasol wheel 7, which helps to support the parasol wheel 7 and enable it to rotate smoothly.

[0028] A second support rod 12 is welded to the top of the motor frame 10. A through hole 14 is provided above the second support rod 12. The shaft 5 passes through the through hole 14. The second support rod 12 helps to support the shaft 5 and enable it to rotate smoothly.

[0029] Working principle: The LNG marine corrugated plate is fixedly installed on the universal clamp 201. The motor 9 is started. The motor 9 drives the parapet wheel 7 to rotate through the shaft 2 8. At the same time, the rotation of the parapet wheel 7 drives the parapet wheel 6 to rotate through the meshing between the gear teeth. The parapet wheel 6 drives the worm gear 4 to rotate through the shaft 5. The worm gear 4 drives the worm wheel disk 3 to rotate through the worm gear transmission. Since the worm wheel disk 3 is connected to the long screw 2, the rotation of the worm wheel disk 3 will cause the long screw 2 to move vertically, which is conducive to completing the lifting and installation operation of the LNG marine corrugated plate.
