Technical Field
The utility model relates to the technical field of belt conveyors, in particular to a deep groove type carrier roller frame structure of a large-inclination-angle belt conveyor.
Background
The belt conveyor is a friction-driven machine for continuously conveying materials, has the advantages of large conveying capacity, simple structure, convenient maintenance, reliable operation, standardized components and the like, is widely applied to a plurality of important production units needing continuous operation, such as coal mine, power plant coal conveying, steel plant and cement plant conveying loose materials or finished articles, an upper groove carrier roller of the belt conveyor is a rotating component for supporting a belt to convey materials, and the structure of a groove carrier roller group directly influences the application of the belt conveyor in coal conveying in a coal conveying roadway at a large inclination angle.
The inclination angle alpha of a coal conveying roadway of the belt conveyor for the coal mine is 16-18 degrees and is not more than 18 degrees, and the inclination angles alpha of carrier rollers on two sides of an upper groove-shaped carrier roller of the belt conveyor are 35-45 degrees, so that the normal coal conveying can be carried out. When the inclination angle alpha of the coal conveying roadway in the inclined upward direction is larger than 18 degrees, the coal conveying roadway belongs to large-inclination-angle roadway conveying, a large-inclination-angle belt conveyor needs to be adopted for conveying, and the inclination angles of carrier rollers on two sides of an upper groove-shaped carrier roller of the belt conveyor are 45-60 degrees. When the inclination angle alpha of the coal conveying tunnel in the inclined direction is 25 degrees, the inclination angles alpha of the carrier rollers on two sides of the upper groove-shaped carrier roller of the adopted coal conveying belt conveyor with the large inclination angle are 60 degrees.
When the inclination angle alpha of the coal transporting tunnel in the inclined upward direction is greater than 25 degrees, namely alpha is 28 degrees, the inclination angles alpha of the carrier rollers at two sides of the groove-shaped carrier roller of the adopted large-inclination-angle belt conveyor are 60 degrees, in the process of transporting coal upwards when the belt conveyor works, the sliding force of the coal on the belt of the belt conveyor is greater than the friction force between the coal and the belt due to the gravity, the coal cannot be transported upwards because the coal slides on the belt of the belt conveyor, and therefore when the inclination angle alpha of the coal transporting tunnel in the inclined upward direction is greater than 25 degrees, namely alpha is 28 degrees, the belt conveyor cannot be used for transporting coal, and only the bucket-lifting belt conveyor with a complex structure and high manufacturing, maintenance and use costs can be used for transporting coal.
