Auxiliary device for replacing conveying belt of belt conveyor

Technical Field

The application relates to the technical field of belt conveyors, and particularly discloses an auxiliary device for replacing a conveyor belt of a belt conveyor.

Background

The belt conveyor is the most ideal efficient continuous transportation equipment in the metallurgy field and the mine field, has the advantages of long transportation distance, large transportation capacity, continuous transportation and the like compared with other transportation equipment, is reliable in operation, is easy to realize automation and centralized control, and becomes the key equipment for transporting raw materials in steel plants. The belt conveyer consists of two end rollers and closed conveyer belt. The roller driving the conveyer belt to rotate is called a driving roller (transmission roller); the other is referred to as a direction-changing drum, which simply changes the direction of movement of the conveyor belt. The driving roller is driven by the motor through the speed reducer, and the conveying belt is dragged by the friction force between the driving roller and the conveying belt. The conveyor belt is the main component for pulling and carrying the material. It should not only have sufficient strength, but also have a corresponding load-bearing capacity. The belt conveyor of the steel plant has the advantages that the belt conveyor is aged quickly due to large transportation capacity, continuous conveying and high stability of conveyed materials, so the belt conveyor needs to be replaced; because the belt conveyor used in the steel plant has long conveying distance and wide conveying belt, spare parts of the conveying belt are heavy (reaching several tons), and the conveying belt is difficult to replace. Traditional conveyer belt is changed and needs large-scale engineering machine tool to hoist the conveyer belt unsettledly, needs manual fit to send into the belt input machine with the spare part conveyer belt at the conveyer belt change in-process, so work efficiency is low, intensity of labour is big, and the safety risk is high, and large-scale engineering machine tool receives the place restriction, consequently, the inventor is in view of the above, provides belt conveyor conveyer belt and changes auxiliary device to solve above-mentioned problem.
