Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is the top view of the utility model under access door open mode.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
This coal pulverizer turns over roller apparatus for examination and repair, comprise coal pulverizer cylindrical shell 4, inner grinding roller 2 and fixed mount 6, in coal pulverizer cylindrical shell 4, be fixed with fixed mount 6, fixed mount 6 is coaxial setting with coal pulverizer cylindrical shell 4, on fixed mount 6, be fixed with grinding roller support 5, inner grinding roller 2 is installed on grinding roller support 5, on coal pulverizer cylindrical shell 4, offer access hole, on coal pulverizer cylindrical shell 4 outer walls of access hole one side, be hinged with access door 1, the radian of access door 1 is consistent with the radian of coal pulverizer cylindrical shell 4, and access door 1 coordinates with access hole; On coal pulverizer cylindrical shell 4 outer walls of access hole opposite side, be provided with and can make the roller mechanism that turns over that inner grinding roller 2 shifts out from access hole.
The described roller mechanism that turns over is included in hard-wired rotating shaft installation sleeve 3 on coal pulverizer cylindrical shell 4 outer walls of access hole opposite side, in rotating shaft installation sleeve 3, be rotatablely equipped with rotating shaft 7, the end of rotating shaft 7 is driven by rotating shaft elevating mechanism, connector 8 is installed in rotating shaft 7, and described grinding roller support 5 is selectively connected with connector 8.
During the action of rotating shaft elevating mechanism, can drive shaft 7 do elevating movement.Rotating shaft elevating mechanism can be hydraulic mechanism.At coal pulverizer cylindrical shell 4 and inner grinding roller 2 contour point position perforates installation and repairing door 1, access door 1 is consistent with coal pulverizer cylindrical shell 4 radians, when coal pulverizer normally uses, access door 1 is closed and the closed one of coal pulverizer cylindrical shell 4, avoid flow-disturbing to affect powder process, access door 1 adopts hinge form, in order to opening and closing.While needing to change grinding roller, access door 1 is opened, and inner grinding roller 2 is shifted out smoothly.
Coal pulverizer cylindrical shell 4 outsides are set up and are turned over roller arrangement mounting bracket, while changing grinding roller, open access door 1, by connector 8, grinding roller support 5 is reliably connected with rotating shaft 7, by hydraulic pump, raise grinding roller support 5, make grinding roller support 5 and access door 1 matched, rotating shaft 7, inner grinding roller 2 is shifted out from access door 1, utilize the equipment such as fork truck that inner grinding roller 2 is unloaded from turning over roller arrangement 3.Another two inner grinding rollers 2 are connected on fixed mount 6 one by one, by fixed mount 6, rotate to access door 1 position, shift out grinding roller with the first grinding roller identical operation.
