Secondly, when installing the scaffolding, it should be installed in a reliable part of the hull, and appropriate measures should be taken to ensure that it is fixed and stable, and there should be no shaking or sliding.

[0003] There is a hatch coaming scaffolding structure with a patent application number of 201120446844.0, which includes a hatch coaming, a lifting lug, a chain and a scaffolding board, wherein the lifting lug is fixedly arranged on the outside of the hatch coaming, and the chain has two pieces. The scaffolding is formed by hanging the scaffolding board on the outside of the hatch coaming through the lifting lug and the chain. The structure is simple, the space is small, the assembly and disassembly are very convenient, the time consumption is short, and other operations will not be affected. Moreover, the position of the scaffolding board can be adjusted by the length of the chain, which is convenient for the staff to operate.

[0004] There are some problems. Chains cannot be used for direct connection, and additional structures are required for connection, which will increase instability. When the lifting lugs are used, they are usually welded or bolted, and the bolted connections may become loose during use, which may cause danger. Therefore, a fixed lifting lug device for oil tanker scaffolding is proposed. Utility Model Content

Based on the described embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1-3 The utility model embodiment proposes a fixed lifting ear device for oil tanker scaffolding, comprising a U-shaped piece 1, both sides of the U-shaped piece 1 are provided with through holes 2, the front of the U-shaped piece 1 is fixedly connected with a mounting seat 3, the mounting seat 3 is rotatably connected with a connecting piece 4, the connecting piece 4 is fixedly connected with a limiting rod 5, the lower side of the front of the U-shaped piece 1 is fixedly connected with a load-bearing rod 6, a disassembly connection component is arranged between the limiting rod 5 and the load-bearing rod 6, and limiting components are arranged on both sides of the U-shaped piece 1.

[0030] The connecting piece 4 is pin-connected to the mounting seat 3 through a pin shaft, and the limiting rod 5 and the load-bearing rod 6 form a U-shape. Openings are provided on the front and top of the mounting seat 3. The connecting piece 4 can be used to allow the limiting rod 5 to rotate away from the load-bearing rod 6, which facilitates the installation and disassembly of the chain. The opening is used for the rotation of the connecting piece 4.

[0031] The disassembly connection assembly includes a connection block 71 fixedly connected to one end of the limit rod 5 and a connection block 72 fixedly connected to one end of the load-bearing rod 6. The end of the connection block 72 away from the load-bearing rod 6 is provided with a protruding block 73, and the outer side of the protruding block 73 is provided with a plurality of splicing threads 74. The end of the connection block 71 away from the limit rod 5 is provided with an embedded groove 710, and the outer sides of the connection block 71 and the connection block 72 are provided with a main body thread 75. The outer side of the connection block 72 is movably connected with a nut 76, and the outer side of the nut 76 is provided with a connecting hole 77. The limit rod 5 is hinged with an arc rod 79. The other end of the arc rod 79 is close to the plug block 78 on one side of the connecting block 71. By disassembling the connecting assembly, the engaging groove 710 on the limit rod 5 and the protruding block 73 are engaged, and then the nut 76 is rotated to allow the nut 76 to rotate to the connection between the engaging groove 710 and the protruding block 73. Subsequently, the arc rod 79 is rotated to allow the plug block 78 to rotate to the connecting hole 77 for insertion. This can prevent the self-rotation caused by external factors such as vibration during use, thereby ensuring the stability of the connection. This is not only convenient for assembling the limit rod 5 and the load-bearing rod 6, but also convenient for separating the limit rod 5 and the load-bearing rod 6, which is easy to use.

[0032] The plug block 78 is made of magnetic material and is matched with the connecting hole 77. The plug block 78 is adsorbed on the connecting hole 77 to prevent it from falling off.

[0033] The protruding block 73 and the splicing thread 74 form a complete thread, the protruding block 73 and the splicing groove 710 are matched, and the nut 1 76 is matched with the whole formed by the protruding block 73 and the splicing groove 710. By utilizing the structure of the protruding block 73 and the splicing thread 74, the nut 1 76 can be moved on the connecting block 1 71 and the connecting block 2 72. By inserting the protruding block 73 into the splicing groove 710, the limiting rod 5 and the load-bearing rod 6 can be connected, which is convenient for the subsequent use of the nut 1 76.

The bottom of the moving block 81 located on the upper side is fixedly connected to a threaded rod 84, and the upper side of the moving block 81 located on the lower side is rotatably connected to a rotating cylinder 83. By using the limiting assembly, after the bolts and nuts are installed on the through holes 2, the nuts and bolt heads are both located on the side close to the limiting seat 82 in the limiting assembly, and then the rotating cylinder 83 is rotated to allow the rotating cylinder 83 to drive the threaded rod 84 to move, thereby allowing the limiting seat 82 to approach the outside of the nut and the bolt head to prevent the nut and bolt head from rotating on their own due to external factors such as vibration, resulting in a loose connection and causing danger.

[0035] The threaded rod 84 is inserted into the rotating cylinder 83 and threadedly connected to the rotating cylinder 83. A sliding groove matching the moving block 81 is opened on the side of the U-shaped piece 1. By rotating the rotating cylinder 83, the rotating cylinder 83 drives the threaded rod 84 to move up and down to control the distance between the two moving blocks 81.

[0036] The specific implementation method is as follows: when in use, the chain can be carried on the load-bearing rod 6 located below, and then the connecting block 1 71 on the limiting rod 5 and the protruding block 73 of the connecting block 2 72 are embedded, so that the splicing thread 74 and the main thread 75 are aligned, and then the nut 1 76 is rotated to make the nut 1 76 be at the connection between the connecting block 1 71 and the protruding block 73, and then the arc rod 79 is swung to allow the plug block 78 to be inserted into the connecting hole 77, which is not easy to separate and can avoid the self-rotation of the nut 1 76, thereby ensuring the stability of the connection. This not only facilitates the installation of the chain but also facilitates the disassembly of the chain. After the bolts and nuts are installed on the through holes 2, the nuts and bolt heads are both on the side close to the limiting seat 82 in the limiting assembly, and then the rotating cylinder 83 is rotated to allow the rotating cylinder 83 to drive the threaded rod 84 to move, so as to allow the limiting seat 82 to approach the outside of the nut and the bolt head to prevent the nut and bolt head from rotating by themselves due to external factors such as vibration, resulting in a loose connection and causing danger.
