[0002] The transmission box of an electric shovel is the component responsible for transmitting power in mechanical equipment. During the operation of the electric shovel, the transmission box will protect the stability and normal operation of the machine, and can realize the speed change of different axes to meet the needs of various tasks. The electric shovel, also known as a rope shovel, is a single-bucket excavator that uses transmission parts such as gears, chains, and steel cable pulleys to transmit power. The transmission box of the electric shovel is a key part of the entire equipment, ensuring that the electric shovel can complete the excavation task efficiently and stably.

[0003] The transmission boxes currently on the market have the following problems when used:

[0004] 1. In actual use, the traditional transmission box is usually composed of transmission parts such as gears, chains, and steel cable pulleys, but it will generate noise during operation. Since there is no separate soundproof structure, the noise reduction effect of the transmission box is weak during use;

[0005] 2. Most transmission boxes need to be fixed by drilling holes and fasteners during use. However, holes may be misaligned during drilling, and the bottom plate can only be removed for secondary fixation. Therefore, the position of the mounting plate cannot be adjusted well during use, and operation is also difficult. Utility Model Content
