The specific implementation mode is as follows:
the invention will be further described with reference to the following examples, which are intended only for better understanding of the invention and therefore do not limit the scope of the invention.
Referring to fig. 1, fig. 2, fig. 3, fig. 4, fig. 5, fig. 6, fig. 7, fig. 8, fig. 9, a vertical mill roller shell assembly and disassembly tool, including the ring layer board that is used for holding up vertical mill roller shell 1, the ring layer board is split type structure, including controlling two circular arc boards 3, weld corresponding bolted connection gusset 5 on the lower terminal surface of two circular arc board 3 links respectively, it has two bolt holes to process on the bolted connection gusset 5, corresponding bolted connection gusset 5 is in the same place through the bolt 6 bolt connection, and then connect two circular arc boards 3 as an organic whole and constitute the ring layer board, four hoisting gusset 4 have evenly arranged on the circumference of ring layer board, hoisting gusset 4 is the L type, with the outer disc and the lower terminal surface welding of ring layer board, the upper portion processing of every hoisting gusset 4 has the hole of hoist and be used for connecting wire rope 7.
The preparation method comprises the following steps:
manufacturing two arc plates 3: the steel plate is made of an arc steel plate with the thickness of 30mm, the outer diameter of 1660mm and the inner diameter of 1460 mm.
Manufacturing four bolt connecting rib plates 5: is made of a steel plate with the thickness of 80mm multiplied by 120mm and is welded with the arc plate 3.
Manufacturing four hoisting rib plates 4: the steel plate is made of an L-shaped steel plate with the thickness of 250mm multiplied by 250mm and 30mm, and is welded with the arc plate 3 four evenly.
The using method comprises the following steps:
during operation, hoisting rib plates 4 on the left arc plate and the right arc plate 3 are horizontally hoisted by a steel wire rope 7 for a crane and are placed below the vertical grinding roller sleeve 1, corresponding bolt connecting rib plates 5 on the two arc plates 3 are butted and connected and fixed by four bolts 6 with the diameter of M24 multiplied by 150mm to form a circular ring supporting plate, the circular ring supporting plate is further sleeved on the roller shaft 2, the circular ring supporting plate is hoisted by the crane through the steel wire rope 7 to support the vertical grinding roller sleeve 1, and therefore the vertical grinding roller sleeve 1 is detached from the roller shaft 2.
The utility model discloses make the dismantlement process of vertical mill roller shell 1 simplify, labour saving and time saving has practiced thrift cost of maintenance, and this instrument can safe frequent use, has improved maintenance efficiency greatly, simple structure, and the cost of manufacture is low, and the practicality is strong, and safe and reliable has avoided the potential safety hazard.
The above description is only a preferred and practical embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent variations made by using the contents of the specification and the drawings are included in the scope of the present invention.
