Description

Technical Field

[0001] The utility model relates to the field of belt conveyor rollers, in particular to a roller group capable of quickly assembling and disassembling rollers. Background Art

[0002] As belt conveyors are increasingly used, rollers, as the main load-bearing components of belt conveyors, play a vital role. As consumable parts, rollers have a certain damage rate and need to be replaced regularly. Traditional roller racks are fixed brackets. Before replacing rollers, it is necessary to release the tension of the belt above the rollers and then lift the belt before replacing the rollers. This has low work efficiency and high labor intensity. Especially for trough rollers, the angle is large and the installation position is relatively high, so replacement is time-consuming and labor-intensive.

[0003] The patent document with announcement number CN202296113U discloses a quick-change trough roller, including two middle pillars and two side pillars, each of which is provided with two staggered notches with openings upward, each of which is provided with a notch with openings upward, the middle trough roller and the two side trough rollers are arranged in a T-shape, the two ends of the middle trough roller are respectively stuck in the notches of the two middle pillars, one end of the side trough roller is stuck in the notch of the middle pillar, and the other end of the side trough roller is stuck in the notch of the side pillar. This roller installation method requires lifting the tape above the roller before replacing the roller, so that the middle trough roller and the two side trough rollers can be taken out from above the notch for replacement, which has low work efficiency and high labor intensity.
