Abstract

The invention discloses an installation accessory of a hanging carrier roller set, and belongs to the technical field of belt conveyors. The mounting accessory comprises a carrier roller fixing piece, a position adjusting plate and a positioning plate. The position adjusting plate is rotatably connected to the idler fixing member in a manner capable of being positioned at least two angles. The hanging pieces at two ends of the hanging carrier roller group sequentially penetrate through the position adjusting plate and the carrier roller fixing piece, and the positioning plate is detachably connected with the hanging pieces, so that the hanging carrier roller group is locked. The carrier roller set can be quickly adjusted to be in a normal working or forward-leaning deviation rectifying position by rotating the position adjusting plate by a specific angle (such as 180 degrees) relative to the carrier roller fixing piece. The invention adopts the conventional materials such as steel plate, round steel and the like, and can be manufactured through simple cutting, drilling and welding, thereby replacing the original complex casting process, obviously reducing the processing cost and working hours, and simultaneously realizing the convenience of installation, adjustment and disassembly.
