Abstract

The invention relates to a rotate tool for disassembly and assembly of a grinding roller device of a medium-speed roller-type coal pulverizer, a maintenance door (8) is arranged on a housing (11) of the coal pulverizer (10), a rotatable main shaft (3) is arranged on one side of the maintenance door (8), the rotatable main shaft (3) is fixed on the housing (11) of the coal pulverizer (10) by two bearings seats (1), the rotatable main shaft (3) is fixedly connected with the grinding roller device (9) by a bracket (4) and a tensioning device (2), and when the an external force is applied to the grinding roller device (9), the grinding roller device (9) may be turned over to the external of the coal pulverizer (10) in the rotation process of the main shaft (3). The rotate tool has the advantages of flexible operation, less occupied space, reduction of the labor intensity of workers, shortening of the maintenance cycle and reduction of the maintenance cost.

Description

technical field [0001] The invention relates to a maintenance tool for disassembling and assembling an internal grinding roller device in a medium-speed roller coal mill without dismantling the coal mill. mounted rotary tool. Background technique [0002] The medium-speed roller coal mill is widely used in the coal pulverization system of electric power, metallurgy, chemical industry, building materials and other industries. There are three grinding roller devices in the coal mill, which are evenly distributed in the coal mill. The grinding roller device is the core grinding part of the medium-speed roller coal mill, which is composed of roller frames, roller sleeves, roller cores, roller shafts, bearings and other parts. The roller sleeves, bearings, roller frames and other parts in the grinding roller device are vulnerable parts, which need to be repaired and replaced after reaching their service life. [0003] Due to the limited operating space inside the coal mill, and...
