The present invention relates to the technical field of roller
changing equipment, and specifically to a roller changing trolley for a
grinding machine, comprising a trolley, a fixed support frame, a rotating support frame and a rolling
assembly, wherein the fixed support frame is arranged on the trolley, a rotating hole is opened on the fixed support frame, the axis of the rotating hole is horizontal, and the rotating support frame is rotatably connected in the rotating hole. The present invention is provided with a rotating support frame, a loading frame and a rolling
assembly, and when the
grinding roller is disassembled and installed, the rolling
assembly is in a rolling state, and at this time, there is rolling friction between the rubber roller and the
grinding roller, and the grinding roller can be quickly placed in the placement hole and the grinding roller in the placement hole can be installed on the grinding
machine, so that the work efficiency can be improved, so that the staff can quickly complete the replacement of the grinding roller, and during the rotation of the rotating support frame, the rolling assembly is in a locked state, and at this time, the rolling assembly limits the movement of the grinding roller along its axis direction, so as to prevent the relative movement between the grinding roller and the placement hole during the rotation of the grinding roller, thereby preventing the occurrence of safety accidents.
