Description

An adjustable lifting lug installation structure for transport aircraft

technical field

The invention relates to the technical field of equipment adjustment, in particular to an adjustable lifting lug installation structure for a transport aircraft.

Background technique

Belt conveyors are widely used in metallurgy, coal, ports, electric power and other fields, and are important material conveying equipment. During the operation of the belt conveyor, belt deviation is a common process phenomenon. Slight deviation can lead to wear of the belt edge, and serious problems can lead to spilled transported materials, or even tearing of the belt and scrapping, which restricts production and cost control. At present, there are two types of deviation adjustment devices commonly used: manual and automatic. The manual type is too simple and cannot meet the production needs well, while the automatic type is expensive and unacceptable to many production units, so the application cannot be popularized.

In the prior art, there is also the phenomenon that the lifting lug is used to adjust the belt deviation on the belt conveyor. Generally, the adjustment groove of the lifting lug adopts a three-point card slot. This kind of lifting lug adjustment device cannot realize the fine adjustment of the belt and the random adjustment of the belt. Therefore, the present invention provides an adjustable lifting lug installation structure for a transporter.
