Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is that proposing a kind of assembled hydraulic cylinder unloads roller mechanism, the quick-replaceable requirement of collars can not only be met, and can breaker roll entirety carry out dismantling and assembling, have simple to operation, efficiency is high, take up room little feature.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of assembled hydraulic cylinder unloads roller mechanism, comprise using first piston 6 as cylinder body, second piston 7 is contained in the interior hydraulic cylinder of composition in first piston 6, is provided with cylinder body 10 outside first piston 6, and cylinder body 10 is connected on suspender by bolt handle, outer hydraulic cylinder is formed with first piston 6, first piston 6 is fixedly connected with fixture 8, and bar cover 3 runs through the second piston 7, is equipped with stock 1 in bar cover 3, stock 1 right part and nut 9 internal-external hexagon are connected, and nut 9 and bar overlap 3 and be fixedly connected with.
Described bar cover 3 is arranged in splicing sleeve 5, and be slidably connected with it, splicing sleeve 5 is arranged between first piston 6 and the second piston 7.
Described bar overlaps 3 leading sections and is provided with screw thread, can be connected with the pull bar 13 of roll assembly.
Described bar cover 3 has the shaft shoulder, and left end end is equipped with handle 2.
Described stock 1 right-hand member is outer-hexagonal structure, can be connected with hexagonal structure in the pull bar 13 of roll assembly.
Be provided with screw thread transparent cover 11 between the port of described cylinder body 10 and first piston 6, cylinder body 10 is fixedly connected with screw thread transparent cover 11 by screw thread.
Described first piston 6 port and bar are provided with transparent cover 12 between overlapping 3, and transparent cover 12 is fixedly connected with first piston 6 by bolt 4.
Because the utility model adopts the combination of two hydraulic cylinders, the quick-replaceable requirement of collars can be met, can breaker roll entirety carry out dismantling and assembling again.Meet instructions for use well, total is compact simultaneously, takes up room little, simple, convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is using state figure of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1, a kind of assembled hydraulic cylinder unloads roller mechanism, comprise using first piston 6 as cylinder body, second piston 7 is contained in the interior hydraulic cylinder of composition in first piston 6, cylinder body 10 is provided with outside first piston 6, cylinder body 10 is connected on suspender by bolt handle, outer hydraulic cylinder is formed with first piston 6, first piston 6 is fixedly connected with fixture 8, extracts roll assembly to transmit pulling force, and bar cover 3 runs through the second piston 7, stock 1 is equipped with in bar cover 3, stock 1 right part and nut 9 internal-external hexagon are connected, and nut 9 and bar are overlapped 3 and be fixedly connected with by screw thread, to locate stock 1.
Described bar cover 3 is arranged in splicing sleeve 5, and be slidably connected with it, splicing sleeve 5 is arranged between first piston 6 and the second piston 7.
Described bar overlaps 3 leading sections and is provided with screw thread, can be connected with the pull bar 13 of roll assembly.
Described bar cover 3 has the shaft shoulder, and left end end is equipped with handle 2.
Described stock 1 right-hand member is outer-hexagonal structure, the outer-hexagonal of stock 1 end can be inserted in pull bar 13 in hexagonal, to be mated connection.
Be provided with screw thread transparent cover 11 between the port of described cylinder body 10 and first piston 6, cylinder body 10 is fixedly connected with screw thread transparent cover 11 by screw thread.
Described first piston 6 port and bar are provided with transparent cover 12 between overlapping 3, and transparent cover 12 is fixedly connected with first piston 6 by bolt 4.
See Fig. 2, operation principle of the present utility model is:
In figure, bold portion is for unloading roller mechanism, and dotted portion is the corresponding roll assembly needing dismounting.
Hollow flange axle 15, the flange 17 of roll assembly clamp collars 16, and pull bar 13 one end is fastening by pull-rod nut 14, and the other end and flange 17 are threaded connection.When roll assembly the whole series are dismantled by needs, unload the outer hydraulic cylinder pressurization of roller mechanism, first piston 6 is to left movement, and fixture 8 is subject to pulling force left, whole roll assembly can be extracted out in rolling-mill housing.
When only needing to change separately collars 16, the pull bar 13 overlapped by bar in 3 front ends and roll assembly is threaded connection, and after connection, interior hydraulic cylinder pressurization, the second piston 7 of interior hydraulic cylinder moves to the shaft shoulder place of bar cover 3 left, and catch bar cover 3 is to left movement.Pull bar 13 extends after being subject to pulling force left, and pull-rod nut 14 and hollow flange axle 15 disengage, and so can eliminate the effect of pretightning force when pull bar 13 is installed, pull-rod nut 14 just can unclamp.After unclamping nut 14, pushed away to the right by pull bar 13 by stock 1, the flange 17 of clamping collars 16 can be unclamped, rotary handle 2 releasing lever 13 is threaded with flange 17.After disengaging, extract pull bar 13 out, can change separately collars 16.
Outer hydraulic cylinder for dismantling whole roll assembly, to carry out inspection and maintenance to whole assembly; Interior hydraulic cylinder is used for the independent replacing of collars 16, can meet rolling different size steel requirement, simple, convenient.
