Description

Technical Field

[0001] The utility model belongs to the field of belt conveyors, and particularly relates to a lightweight combined idler support. Background Art

[0002] Belt conveyors are continuously operating transportation equipment and are modern large-scale transportation equipment with long distances, large transportation volumes, and high powers. They play a significant role in heavy industrial fields such as metallurgy, mining, food, and building materials, as well as in the transportation field. With the increasing shortage of world energy, coal mining is imminent. However, as a highly efficient continuous transportation equipment, compared with other transportation equipment, belt conveyors not only have the advantages of long distance, large transportation volume, and continuous transportation, but also operate reliably and are easy to achieve automation and centralized control. They are particularly suitable for high-yield and high-efficiency transportation. Belt conveyors have become key equipment for the mechatronics technology and equipment of high-efficiency coal mining.

[0003] However, currently, the belt widths of belt conveyors can range from below 500mm to over 2000mm, and even up to 3000mm. Even the most commonly used widths of 800mm - 1400mm vary greatly, making it impossible to share components, resulting in a large number and variety of coal mine spare parts. Moreover, currently, the large structural parts and the fuselage of belt conveyors are basically made of carbon steel. Occasionally, materials such as stainless steel are used, but they are all very heavy, and transportation, disassembly, and assembly are extremely inconvenient, which will greatly increase the workload and working intensity, causing great adverse effects on both the manufacturing factory and the user.

For this purpose, a lightweight combined idler support is provided, which includes idler struts, intermediate connecting rods, and frame connection seats. On both sides of the side wall of the intermediate connecting rod, a group of idler struts are arranged respectively. The frame connection seat is located outside the idler struts and connects the intermediate connecting rod and the frame of the belt conveyor. The idler struts include middle struts and side struts, and the number of both is two. Both the middle struts and the side struts can change their positions relative to the intermediate connecting rod and be locked. A space for installing bottom idlers is left between the two middle struts and is located in the middle of the intermediate connecting rod. The two side struts are located at both ends of the intermediate connecting rod, and a space for installing side idlers is left between the side struts and the adjacent middle struts.
