Technical Field

[0001] The utility model relates to the technical field of self-unloading ships, in particular to a detachable hole cover structure of a conveying hole of a conveyor belt of a self-unloading ship. Background Art

[0002] It is well known in the water transport industry that a self-unloading ship is a large transport ship, which refers to a cargo ship with unloading equipment equipped with an automatic control device and can automatically and continuously complete unloading operations at high speed. On board, workers do not directly participate in the operation, but only need to make necessary adjustments and controls to the equipment. The unloading efficiency is high and the turnover is fast, but the cost is high. Compared with conventional bulk carriers of the same carrying capacity, the main dimensions and empty displacement of a self-unloading ship are larger. A self-unloading ship mainly relies on high unloading efficiency and fast turnover to obtain good economic benefits, while saving equipment investment at the arrival terminal. Self-unloading ships are generally suitable for routes with shorter voyages and poor equipment at the arrival terminal.

[0003] A self-unloading ship is a dry bulk cargo transport ship that can unload cargo in a continuous conveying manner. The conveyor belt is an important carrier for the self-unloading ship to continuously convey cargo. Therefore, when designing and manufacturing a self-unloading ship, the installation of the conveyor belt becomes a top priority.

[0004] In the past, the removable hole cover for the conveyor belt of the self-unloading ship was in the form of an ordinary manhole cover, with bolts passing from the outside to the inside and nuts fixed inside.

DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0027] Reference Figure 1-6As shown, the detachable hole cover structure of the conveying hole position of the self-unloading ship conveyor belt of the utility model comprises: a seat plate 1, a cover plate 2 and several bolts 3 as main parts; the seat plate 1 is welded at the internal position of the hole position of the cabin body, and a through hole 11 is opened on the seat plate 1, and a plurality of mounting holes 12 are arranged on the seat plate 1, and the plurality of mounting holes 12 are located around the through hole 11; the cover plate 2, whose cross-sectional area is larger than the cross-sectional area of ​​the through hole 11, the cover plate 2 is arranged at the position of the through hole 11, and the cover plate 2 is located outside the hole position of the cabin body, and a plurality of threaded holes 21 are arranged on the cover plate 2, and the plurality of threaded holes 21 and the plurality of mounting holes 12 are arranged in a one-to-one correspondence; the bolts 3 are arranged in a plurality, and the plurality of bolts 3, the plurality of threaded holes 21 and the plurality of mounting holes 12 are arranged in a one-to-one correspondence, and the bolts 3 pass through the mounting holes 12 from the inside of the hole position of the cabin body and are locked with the threaded holes 21.

[0028] In the above structure, a plurality of toggle plates 4 are connected to the end surface of the seat plate 1 located inside the cabin, and the toggle plates 4 and the seat plate 1 are vertically arranged.

[0029] In the above structure, the cover plate 2 is a rectangular flat plate, and the four corners of the cover plate 2 are all rounded, and a plurality of threaded holes 21 are arranged along the edges of the cover plate 2. The threaded holes 21 are formed by tapping M20 bolt holes on the cover plate 2, and are used as bolt fastening holes for fixing the cover plate.

[0030] In the above structure, a plurality of reinforcing angle steels 1 5 are provided at the center line position in the length direction of the cover plate 2, and the reinforcing angle steels 1 5 are arranged on the end surface of the cover plate 2 close to the interior of the cabin. A plurality of reinforcing angle steels 2 6 and a plurality of reinforcing angle steels 3 7 are provided on the cover plate 2, and the plurality of reinforcing angle steels 2 6 are arranged in a row, and the plurality of reinforcing angle steels 3 7 are arranged in a row, and the plurality of reinforcing angle steels 2 6 and the plurality of reinforcing angle steels 3 7 are all arranged on the end surface of the cover plate 2 close to the interior of the cabin. The plurality of reinforcing angle steels 2 6 and the plurality of reinforcing angle steels 3 7 are all located on the end surface of the cover plate 2 close to the interior of the cabin. The functions of the reinforcing angle steels 1 5, 2 6 and 3 7 are mainly achieved by using composite fiber reinforced materials, which are closely combined by metal materials (such as iron, steel) and fiber reinforced materials (such as glass fiber, carbon fiber) through composite technology, thereby improving the strength, corrosion resistance and construction convenience of the angle steel. In addition, the reinforcing angle steels 1 5, 2 6 and 3 7 themselves have the characteristics of high strength and corrosion resistance, and can withstand great forces, ensuring that the building will not be deformed or damaged during long-term use. The angle steel is relatively light, which can reduce the deadweight of the seat plate 1 and improve the earthquake resistance.

[0031] In the above structure, the through hole 11 is a rectangular hole, and the four corners of the through hole 11 are all set to be rounded corners, and the center of the cover plate 2 coincides with the center of the through hole 11.

[0032] In the above structure, a flat washer 8 is provided between the bolt 3 and the seat plate 1. The flat washer 8 is used to reduce friction, prevent leakage, isolate, prevent loosening or disperse pressure. Due to the material and process limitations of threaded fasteners, the bearing surface of fasteners such as bolts is not large, so in order to reduce the compressive stress of the pressure-bearing surface, the surface of the connected part is protected. A spring washer 9 is provided between the bolt 3 and the seat plate 1. The spring washer 9 can prevent loosening and increase the preload force, while the flat washer does not have this function. It can be used to increase the fastening contact area, prevent friction between the bolt and the workpiece, and protect the surface of the connecting part to prevent the surface of the workpiece from being scratched when the bolt and nut are tightened.

[0033] In the above structure, the seat plate 1 is a rectangular flat plate, and the four corners of the seat plate 1 are all set to rounded corners, and a number of mounting holes 12 are set along the edges of the seat plate 1. The mounting hole 12 is an opening of φ24, and the position of the mounting hole 12 on the seat plate 1 must be aligned with the position of the threaded hole 21 on the cover plate 2 to ensure smooth installation of the bolt. Pass the M20x60 hexagonal head bolt through the bottom of the seat plate 1 and tighten it to the cover plate 2. The bolt 3 is tightened with a leveling washer and a spring washer, and the spring washer has the function of locking the bolt.

[0034] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
