Description

Technical Field

[0001] The utility model relates to the technical field of hoppers, in particular to a special hopper for loading pig iron onto ships. Background Technique

[0002] A hopper is a device used to load pig iron from a storage area onto a ship. It usually has a strong structure, high-temperature resistant materials, and is designed with a dumping or discharging system to efficiently and safely transfer pig iron into the ship's hold. This hopper helps improve the efficiency and accuracy of the ship loading operation.

[0003] When using a grab bucket to load pig iron blocks onto a barge, due to the large volume of the pig iron blocks, whether using a lotus grab bucket or a flat mouth grab bucket, the bucket mouth will be clamped. The grab bucket often clamps the iron blocks and cannot close completely, resulting in the pig iron blocks spilling along the closing path and posing a risk of high-altitude falling objects.

[0004] Therefore, we propose a special hopper for loading pig iron onto ships to solve the problems mentioned above. Content of the Utility Model

[0005] The purpose of the utility model is to provide a special hopper for loading pig iron onto ships to solve the problem that the grab bucket often clamps the iron blocks and cannot close completely as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A special hopper for loading pig iron onto ships, including a hopper structure, and the hopper structure includes a fixed member and a movable member installed on one side inside the fixed member;

[0007] The fixed member includes an inclined long plate A and an inclined long plate B arranged on one side of the inclined long plate A, and an inclined short plate A is installed between the same ends of the inclined long plate A and the inclined long plate B;

[0008] The movable member includes an inclined short plate B, and the inclined short plate B is installed inside between the inclined long plate A and the inclined long plate B. A bottom plate is installed between the lower ends of the inclined long plate A, the inclined short plate A, the inclined long plate B, and the inclined short plate B, and the bottom plate is welded to the inclined long plate A, the inclined short plate A, and the inclined long plate B, and the side end of the inclined short plate B is in contact with one end of the bottom plate.

[0009] Preferably, the bottom end of the bottom plate is higher than the bottom end of the inclined long plate A, and the bottom ends of the inclined long plate A, the inclined short plate A, the inclined long plate B, and the bottom plate are at the same level.

[0010] Preferably, lifting lugs A are installed on both sides of one end of the inclined short plate A, and lifting lugs B are installed on both sides of one end of the inclined short plate B.

[0011] Preferably, a lower strip is installed on the lower side of one end of the inclined short plate B, and the lower strip is located at the bottom end of the bottom plate.

[0012] Preferably, lower blocks are installed on both sides of the bottom end of the bottom plate, and through holes are formed in the middle ends of the two lower blocks.

[0013] Preferably, rotating shafts are installed at both ends of the lower strip, and the rotating shafts are movably installed inside the through holes.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] (1) For the special hopper for pig iron loading onto ships of the present utility model, when the hopper structure is placed on the ground, the bottom ends of the inclined long plate A, the inclined short plate A, the inclined long plate B and the inclined short plate B are in full contact with the ground surface. Pig iron can be put into the hopper composed of the inclined long plate A, the inclined short plate A, the inclined long plate B, the bottom plate and the inclined short plate B for loading. After the pig iron loading is completed, the gantry crane contracts the fixed-length steel wire rope, and the inclined short plate B maintains its original position under the upward pulling force of the fixed-length steel wire rope, reducing the risk of high-altitude falling objects.

[0016] (2) For the special hopper for pig iron loading onto ships of the present utility model, when the hopper structure moves down to the position where pig iron can be dumped, the fixed-length steel wire rope can stop releasing. The fixed-length steel wire rope of the lifting lug B installed inside the inclined short plate B is continuously released. One end of the fixing member moves downward, making the fixing member inclined. As the fixed-length steel wire rope is released, the rotating shaft rotates inside the through hole, and the lower end of the inclined short plate B rotates along the rotating shaft, facilitating the dumping of the pig iron inside the hopper structure.

Detailed Embodiment

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1: Please refer to Figure 1 , Figure 2 and Figure 4 , a special hopper for loading pig iron onto ships, including a hopper structure 1, and the hopper structure 1 includes a fixed member 11 and a movable member 12 installed on one side inside the fixed member 11.

[0024] The fixed member 11 includes an inclined long plate A111 and an inclined long plate B113 arranged on one side of the inclined long plate A111. An inclined short plate A112 is installed between the same ends of the inclined long plate A111 and the inclined long plate B113.

[0025] The movable member 12 includes an inclined short plate B121. The inclined short plate B121 is installed inside between the inclined long plate A111 and the inclined long plate B113. A bottom plate 115 is installed between the lower ends of the inclined long plate A111, the inclined short plate A112, the inclined long plate B113, and the inclined short plate B121. Moreover, the bottom plate 115 is welded to the inclined long plate A111, the inclined short plate A112, and the inclined long plate B113. The side end of the inclined short plate B121 is in contact with one end of the bottom plate 115 without any gap, preventing pig iron with a relatively small volume from getting stuck between the side end of the inclined short plate B121 and the bottom plate 115, which may affect the normal rotation of the inclined short plate B121. The inclined long plate A111, the inclined short plate A112, the inclined long plate B113, the bottom plate 115, and the inclined short plate B121 form a hopper to carry and transport pig iron.

[0026] The bottom end of the bottom plate 115 is higher than the bottom end of the inclined long plate A111. The bottom ends of the inclined long plate A111, the inclined short plate A112, the inclined long plate B113, and the inclined short plate B121 are flush, facilitating the hopper structure 1 to be placed horizontally on the ground. The bottom end of the inclined short plate B121 is in full contact with the ground to fix the position of the inclined short plate B121 and prevent the inclined short plate B121 from rotating. At this time, the inclined short plate B121 and the inclined short plate A112 are in a symmetric position, facilitating the loading of pig iron into the hopper structure 1.

[0027] On both sides of one end of the inclined short board A112, lifting lugs A114 are installed. On both sides of one end of the inclined short board B121, lifting lugs B122 are installed. The fixed-length steel wire rope in the gantry crane is connected to the lifting lugs B122 and A114 for lifting and lowering the hopper structure 1. The positions where the lifting lugs A114 and B122 are installed are at the upper inner side of the hopper structure 1 to prevent the pig iron from damaging the fixed-length steel wire rope when pouring the pig iron, thus affecting the safety of the gantry crane when handling the pig iron.

[0028] In this embodiment: On both sides of one end of the inclined short board A112, an inclined long board A111 and an inclined long board B113 are respectively installed. The inclined short board B121 is installed between the inclined long board A111 and the inclined long board B113. The fixed-length steel wire rope on the gantry crane is connected inside the lifting lugs A114 and B122. When the hopper structure 1 is placed on the ground, the bottoms of the inclined long board A111, the inclined short board A112, the inclined long board B113, and the inclined short board B121 are in full contact with the ground surface. At this time, both sides of the inclined short board B121 are in contact with the surfaces of the inclined long board A111 and the inclined long board B113, preventing gaps from existing between the inclined short board B121 and the inclined long board A111 and the inclined long board B113. The pig iron can be poured into the hopper formed by the inclined long board A111, the inclined short board A112, the inclined long board B113, the bottom plate 115, and the inclined short board B121 for loading the pig iron. After the pig iron is loaded, the gantry crane contracts the fixed-length steel wire rope, and the inclined short board B121 is lifted by the fixed-length steel wire rope and remains in its original position, preventing gaps from occurring.

[0029] Embodiment 2: Please refer to Figure 3 and Figure 4 , a lower strip 123 is installed on the lower side of one end of the inclined short board B121, and the lower strip 123 is at the bottom end of the bottom plate 115. The width of the lower strip 123 is smaller than the distance between the lower ends of the inclined long board A111 and the inclined long board B113, facilitating the rotation of the lower strip 123 and the inclined short board B121 between the inclined long board A111 and the inclined long board B113.

[0030] On both sides of the bottom end of the bottom plate 115, lower blocks 116 are installed, and through holes 117 are drilled through the middle of the two groups of the lower blocks 116. The length of the lower strip 123 is the same as the distance between the two groups of lower blocks 116.

[0031] On both ends of the lower strip 123, rotating shafts 124 are installed, and the rotating shafts 124 are movably installed inside the through holes 117, facilitating the position constraint of the rotating lower strip 123 and the inclined short board B121 and preventing the movable member 12 from falling off.

[0032] In this embodiment: During unloading, the gantry releases the fixed-length wire rope, and the hopper structure 1 moves downward. When the hopper structure 1 moves downward to a position where pig iron can be dumped, the release of the fixed-length wire rope can stop. Then, continue to release the fixed-length wire rope of the lifting lug B122 installed inside the inclined short board B121. One end of the fixing member 11 moves downward, making the fixing member 11 inclined. As the fixed-length wire rope is released, the rotating shaft 124 rotates inside the rotating hole 117, and the lower end of the inclined short board B121 rotates along the rotating shaft 124, facilitating the dumping of the pig iron inside the hopper structure 1. The rotatable inclined short board B121 can prevent the pig iron from getting stuck between the lifting lug B122, the inclined long board A111, and the inclined long board B113.

[0033] Working principle: When the hopper structure 1 is placed on the ground, the bottoms of the inclined long board A111, the inclined short board A112, the inclined long board B113, and the inclined short board B121 are in full contact with the ground surface. Pig iron can be fed into the hopper structure 1 for loading. After the pig iron loading is completed, the gantry contracts the fixed-length wire rope. The inclined short board B121 is kept in its original position due to the upward pulling force of the fixed-length wire rope, reducing the risk of falling objects from a height. During unloading, the gantry releases the fixed-length wire rope, and the hopper structure 1 moves downward. When the hopper structure 1 moves downward to a position where pig iron can be dumped, the release of the fixed-length wire rope can stop. Then, continue to release the fixed-length wire rope of the lifting lug B122 installed inside the inclined short board B121. The fixing member 11 is inclined. As the fixed-length wire rope is released, the lower end of the inclined short board B121 rotates along the rotating shaft 124, facilitating the dumping of the pig iron inside the hopper structure 1. The rotatable inclined short board B121 can prevent the pig iron from getting stuck between the lifting lug B122, the inclined long board A111, and the inclined long board B113.
