Description

Technical Field

[0001] The utility model belongs to the technical field of motor equipment, and in particular relates to a vertical motor installation mechanism for coal mines. Background Art

[0002] A coal mine is an area where humans exploit coal resources in coal-rich mining areas. It is generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, people generally choose to directly strip off the surface soil layer to mine coal. This is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines. The scope of coal mines includes a large area above and below the ground and related facilities. Coal mines are reasonable spaces excavated by humans when digging geological strata rich in coal, usually including tunnels, shafts, mining faces, etc.

[0003] Coal mining requires the use of various mechanical equipment, and the operation of mechanical equipment is inseparable from the drive of motors. Therefore, the stable installation of motors is particularly important. The temperature of the motor will rise during operation. In order to ensure the stable operation of coal mine motors, coal mine motors are generally equipped with cooling fans. When the coal mine motors are working, the cooling fans are driven to rotate, driving the airflow to blow to the motors to dissipate heat. However, the installation mechanism of the motor used for installation is fixed on the side of the motor, or the working environment of the motor is complex, which affects the heat dissipation, and eventually the motor temperature is too high and burns, causing property loss.

[0004] In view of the shortcomings of existing technologies, further improvements are needed. Utility Model Content
