At the beginning of the 19th century, the use of aerial ropeways began to transport bulk materials in the United States of America. By the middle of the 19th century, a variety of conveyors with various structures began to appear one after another. In England, the belt conveyor was introduced in 1868; in 1887, the screw conveyor also appeared in the United States; at the beginning of the 20th century, Switzerland, the United Kingdom, and Germany respectively developed steel belt conveyor lines and inertial lines. Then in the following decades, due to the influence of industrial developments such as metallurgy and chemical industry, belt conveyors have also been continuously innovated and continuously improved.
After the explanation, we will return to the topic and talk about the specific classification of conveyor belts: conveyor belt equipment with traction elements, and various types of conveyor belt equipment with traction elements, mainly escalators, moving walkways, belt conveyor lines, bucket elevators, suspensions Conveyor lines, belt mesh conveyors, plate chain conveyors, trolley-type assembly lines, scraper/embedded scraper conveyors and aerial ropeways.
The structural features of the traction device are directly mounted on the traction device (such as the conveyor belt) or the traction device and the transportation material are installed in a load member connected together, and the traction device bypasses all the sprocket or the roller and then the head and the tail. Next, a closed loop is formed of the no-load and load-bearing branches of the non-conveyed material containing the conveyed material, and the continuous motion of the traction element is used to transport the material. The traction member conveyor generally includes a traction member, a tensioner, a redirecting device, a load member, a drive device, a support member, and the like.
Traction members are generally used to transmit traction. They can use conveyor belts, wire ropes, or traction chains. Load components are used to load cargo, hoppers, spreaders, or brackets, etc.; 2. Tensioners are generally heavy hammer type and screw type. In both cases, the traction members can maintain a certain tension and sag to ensure the normal operation of the conveyor belt; 3, the drive device provides power to the conveyor, and is generally composed of a motor, a brake (stopper), and a speed reducer; The support member is generally used to support the traction member or the load member, and a support roller, a roller, and the like can be used. The composition of beltless conveyor equipment is different, and the working components used to transport cargo are also different.
