Description
Technical Field
The invention relates to a vertical mill, in particular to a roller sleeve dismounting tool of a vertical mill.
Background
At present, the roll sleeve of the vertical mill needs to be turned over and replaced regularly, but in the dismounting process, four 50-ton jacks are needed to horizontally jack up the roll sleeve for 200mm, and then the roll sleeve is fixed by four steel wire ropes and then hoisted, so that time and labor are wasted, and great potential safety hazards exist in the process of fixing the roll sleeve by the steel wire ropes and in the subsequent hoisting process.
Disclosure of Invention
The invention aims to solve the problems, and provides a safe and reliable vertical mill roller sleeve dismounting tool which can realize quick dismounting and mounting and improve maintenance efficiency.
The invention solves the problems and adopts the technical scheme that:
the utility model provides a vertical mill roller shell assembly and disassembly tools, including the ring layer board that is used for holding up vertical mill roller shell, the ring layer board is split type structure, including controlling two circular arc boards, be provided with corresponding bolted connection gusset on the lower terminal surface of two circular arc board links respectively, be provided with the bolt hole on the bolted connection gusset, corresponding bolted connection gusset passes through bolted connection together, and then connect two circular arc boards and constitute the ring layer board as an organic whole, evenly arranged four at least hoist and mount gussets on the circumference of ring layer board, be provided with the hole for hoist and mount that is used for connecting wire rope on the hoist and mount gusset.
Compared with the prior art, the invention adopting the technical scheme has the outstanding characteristics that:
the vertical mill roller sleeve dismounting process is simplified, time and labor are saved, maintenance cost is saved, the tool can be used safely and frequently, maintenance efficiency is greatly improved, the structure is simple, manufacturing cost is low, practicability is high, safety and reliability are achieved, and potential safety hazards are avoided.
Preferably, the further technical scheme of the invention is as follows:
the hoisting rib plate is L-shaped and is welded with the outer circular surface and the lower end surface of the circular ring supporting plate, and the hoisting hole is formed in the upper part of the hoisting rib plate.

in the figure: a vertical mill carrier roller 1; a roll shaft 2; an arc plate 3; hoisting a rib plate 4; the bolt is connected with a rib plate 5; a bolt 6; a steel cord 7.
The specific implementation mode is as follows:
the invention will be further illustrated by the following examples, which are intended only for a better understanding of the present 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 vertical mill roller sleeve 1 dismounting tool has the advantages that the dismounting process of the vertical mill roller sleeve 1 is simplified, time and labor are saved, the maintenance cost is saved, the tool can be used safely and frequently, the maintenance efficiency is greatly improved, the structure is simple, the manufacturing cost is low, the practicability is high, the safety and the reliability are realized, and the potential safety hazard is avoided.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, which is defined in the appended claims.
