Description

Technical Field

[0001] The utility model relates to the technical field of high-strength fans for mines, in particular to a high-strength fan for mines. Background Art

[0002] Mining fans are mechanical equipment used for ventilation, exhaust or cooling in mines and similar industrial environments. They play a vital role in mines, tunnels, underground projects and other places, providing necessary ventilation and air circulation for the working environment and ensuring the health and safety of workers. Mining fans are usually divided into two main types: axial flow fans and centrifugal fans. Axial flow fans are suitable for occasions requiring a large amount of air flow, such as mine ventilation; while centrifugal fans are suitable for occasions requiring higher wind pressure, such as underground tunnel exhaust. Mining fans are usually made of high-strength, wear-resistant and corrosion-resistant materials, such as high-quality steel or special alloys. The fan's blades, casing, impeller and other components must be precisely processed and balanced to ensure their stability and safety when running at high speeds. Modern mining fans are usually equipped with advanced operation control systems that can realize functions such as automatic control, speed and air regulation. Mining fans are usually composed of larger fan blades, motors and casings, and are heavy. The function of the bracket is to bear and support the weight of the fan to ensure that it is stably installed in the required position. Mining fans will generate greater vibration and impact force during operation, especially when running at high speeds. The bracket can stabilize the fan, prevent it from excessive shaking and deformation, and maintain its balance and stability in the working environment.

[0003] Existing mining fans will generate large vibrations and impact forces during operation, especially when running at high speeds. Conventional brackets will cause displacement and fall apart after long-term use. The displacement or fall apart of the bracket may cause the overall instability of the fan, increasing the safety risk during the operation of the fan. If the bracket falls apart completely or partially loosens, the fan may lose balance, resulting in severe vibration, tilting or even collapse, causing personal injury or equipment damage. Therefore, in response to the above problems, the inventor proposes a high-strength mining fan to solve the above problems. Utility Model Content
