Background

A belt conveyor is a simple mechanical device for conveying materials by converting electric power into friction force through a conveying belt. The belt conveyor is simple to manufacture, low in cost and high in conveying speed, can continuously convey materials in a short distance or a long distance, and is widely applied to places such as factories, wharfs, warehouses, mines and mixing stations. The belt conveyor mainly comprises components such as an electric roller, a bend roller, a carrier roller bracket, a carrier roller, a conveying belt, a sweeper, a rack, supporting legs and the like. The conveyer belt is made by canvas and rubber processing, and in the material production transportation process, the impact and the friction of material are directly born to the conveyer belt, especially to the wearing and tearing of conveyer belt when transporting slay or rubble more serious. The conveyer belt must be changed after receiving serious wearing and tearing as the vulnerable part and can normally work, receives the limited space influence, and it is consuming time and arduous to change the conveyer belt.

According to the requirements of actual construction and production, the belt conveyor needs to be disassembled, assembled and transported in a transition mode for many times. Because the part of the upper carrier roller bracket of the belt conveyor, which protrudes out of the top surface of the frame, is higher, the upper carrier roller bracket is easy to deform or damage under pressure, so that the upper carrier roller bracket cannot be stacked and loaded, the vehicle and the transportation cost are increased during transition transportation, and particularly, a large amount of transportation cost is required to be paid for more than one ore or gravel processing equipment with a large number of belt conveyors during transition transportation. Therefore, to avoid damage to the upper idler supports during transport, the upper idler supports are typically removed from the frame and transported. However, in the prior art, the two ends of the upper idler support are usually connected with the frame of the belt conveyor through bolts, so that a wrench and other tools are required for disassembly, and the disassembly and the assembly are time-consuming and labor-consuming.
