During the ship construction process, a large amount of materials (such as decoration materials, equipment and the like) need to be transported to a ship; meanwhile, a large amount of garbage in the ship also needs to be transported to a wharf or outside the ship from the ship and then transported to a garbage yard. At present, the common practice is to place the material into the material hopper, then use the wharf crane to hoist the material hopper and the material together onto the deck of the ship, and finally transfer the material to each position on the ship, or load the garbage on the ship onto the material hopper of the ship, and then transport the material hopper and the garbage to the wharf or the outside of the ship through the wharf crane. The problems of the wharf crane are as follows: 1. the adaptability is not strong for the conditions of scattered materials and large quantity, and the hoisting preparation time of the wharf crane is too long, so that the efficiency is low; 2. the wharf crane often serves a plurality of ships at the same time, and if the lifting material quantity is large, the crane is difficult to meet the lifting requirements of the plurality of ships at the same time.

When the distance between the second concentric wheel 1243 and the inner side of the first wing 1112 is too large, the eccentric shaft 1241 can be rotated to reduce the distance between the second concentric wheel 1243 and the inner side of the first wing 1112; when the distance between the second concentric wheel 1243 and the inner side of the first wing 1112 is too small, the eccentric shaft 1241 can be rotated to increase the distance between the second concentric wheel 1243 and the inner side of the first wing 1112, so that the first wing 1112 is just clamped between the inner roller 124 and the outer roller 125. During actual rolling, the eccentric shaft 1241 is fastened to the roller frame 121, the second concentric wheel 1243 rolls with respect to the first concentric wheel 1242, and the first concentric wheel 1242 and the eccentric shaft 1241 do not rotate.

For the working process that the ship material hoister of the embodiment lifts materials into a ship, the main steps are as follows: 1. a worker loads materials on a wharf or other small ship platforms or on the shore into the material hopper 200; 2. the suspension cage 2 is driven by the driving mechanism 3 to do descending movement until a pressure contact of a position sensor 24 at the bottom of the suspension cage 2 abuts against a wharf or other small ship platforms or a shore, and the suspension cage 2 stops moving; 3. the front door 23 of the cage 2 is opened, and a worker uses a carrying tool such as a forklift to feed the material hopper 200 into the cage 2; 4. the suspension cage 2 is driven by the driving mechanism 3 to do ascending movement until the ship unloading outlet of the suspension cage 2 ascends to the position of the inlet 101 of the ship needing to convey materials, and the suspension cage 2 stops ascending; 5. the split doors 22 of the cage 2 are opened and the crew quickly transfers the material into the vessel.

The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description of the present invention, which should be interpreted as a limitation.
