Technical Field
[0001] The utility model relates to the technical field of sand dredging ships, in particular to a gear box body structure of a sand dredging ship. Background Art
[0002] A sand dredger is a floating mining and selection combined device for mining underwater sand deposits or loose materials. The ore sand is mined by the excavation mechanism installed on the flat-bottomed bow and lifted to the ship's silo. After being crushed, washed and graded by the circular screen, the fine-grained materials containing ore flow by gravity into the roughing chute or jig for roughing. The tailings are discharged into the goaf behind the stern through the tailings chute or sand pump, and the waste rock on the circular screen is discharged into the tailings pile behind the stern through the belt conveyor or gravel chute. Since this type of floating device was originally used to mine gold in New Zealand, it was named a gold dredger. Later, it was also used to mine platinum, cassiterite, diamond, rutile, monazite, zircon, sulfur, phosphate, coal, silver, ilmenite, silver-containing lead-zinc ore, iron sand, niobium, tantalum, thorium and other minerals and sand and pebbles for construction. All methods of mining useful minerals with sand dredging ships are collectively referred to as sand dredging ship mining, or ship mining for short. The box structure of the sand dredging ship gearbox usually adopts a variety of installation methods such as horizontal, vertical, swing base, and torque arm to adapt to different working conditions and needs. These installation methods ensure that the gearbox can stably withstand the force from the wind wheel and the reaction force generated during gear transmission, and has sufficient rigidity to prevent deformation, thereby ensuring the transmission quality. The main function of the gearbox is to transmit the power generated by the wind wheel under the action of wind to the generator, and realize power transmission through the speed increase effect of the gear pair, so it is also called a speed increaser. In the application of sand dredging ships, the gearbox also plays a key role. Through its speed increase function, the sand dredging ship can efficiently complete the sand mining operation. With the development of society, the box structure is used when the gearbox of the sand dredging ship needs to be protected.
[0003] When workers need to control the sand mining ship to move forward, they control the gearbox so that the gearbox can transmit power. However, the existing gearbox structure will allow sand and gravel to enter after long-term use, causing a large amount of sand and gravel to accumulate inside the gearbox, which will lead to serious wear of the internal parts of the gearbox.
