The utility model has advantages below compared with prior art：
1st, the rolling sleeve pipe being sleeved on by rolling bearing on axis of traction is provided with the utility model, and is had on the axis of traction
The suspension parts being used cooperatively with overhead traveling crane pull rope, simple in construction, in use, rolling with cylinder steel plate, lodge is rolling
Cylinder turnup end on sleeve pipe can adjust height with the lifting or reduction of frock, as rolling sleeve pipe is on axis of traction
Rotate and rotate, realized with this and easily and efficiently roll traction auxiliary, it is not necessary to stop rolling the position that can also adjust cylinder,
Operating efficiency is improved, reduces cylinder roundness error, ensures production safety.
2nd, the utility model frock is applied to the plate welding type cylinder of any material, versatile.
3rd, in the utility model, rolling bearing, locating ring and spacing ring are further located at axis of traction both ends by different level, and limit
There is the projection to be offseted with locating ring on the ring of position so that rolling sleeve pipe can be sleeved on axis of traction relatively stablely.
Brief description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In figure：1- rolls sleeve pipe, 2- axis of traction, 3- rolling bearings, 4- locating rings, 5- spacing rings.
Embodiment
As shown in figure 1, a kind of major diameter ultra-thin-wall shell rolling traction frock, the frock include axis of traction 2, are sleeved on
Rolling sleeve pipe 1 on the axis of traction 2 and being symmetrically arranged at rolls the spacing ring 5 at the both ends of sleeve pipe 1, the spacing ring 5 on axis of traction 2
The moving left and right in the axial direction of sleeve pipe 1 is rolled for limiting；By being sleeved on the axis of traction 2 between axis of traction 2 and rolling sleeve pipe 1
On rolling bearing 3 be flexibly connected, rolling bearing 3 and roll sleeve pipe 1 between appropriate gap be present, when have cylinder lodge pressure
When, roll sleeve pipe 1 and contacted with rolling bearing 3 and then realize rolling freely the rotating on axis of traction 2 of sleeve pipe 1；Axis of traction 2 is by limiting
Suspension parts is provided with the both ends that the position center of ring 5 is stretched out, the suspension parts can be the card that can be used cooperatively with overhead traveling crane pull rope
Groove or through hole.
In practical application, for overhead traveling crane pull rope usually using steel wire rope, rolling sleeve pipe 1 can use seamless steel pipe to manufacture；Lead
Draw axle 2 to process using round steel；The selection standard rolling bearing of rolling bearing 3；Spacing ring 5 is processed using steel plate.Spacing ring 5 and lead
Draw axle 2 to connect using welding manner, using flexible connection between other parts.
Above-mentioned frock is in use, (1) first hangs the neck at the both ends of axis of traction 2 or through hole to overhead traveling crane via haulage cable
Suspension hook on, and frock is adjusted to proper height；(2) during shell rolling, shell rolling roll of steel plate origin or beginning lodge is existed
Roll on sleeve pipe 1, frock is lifted with the rise overhead traveling crane of steel sheet edge folded part, when cylinder steel plate rises to peak (in cylinder
Footpath size is adapted) when overhead traveling crane stop movement；(3) progress rolled with steel plate, turned up portion is with turn for rolling sleeve pipe 1
It is dynamic and freely sagging, until being docked with the other end；(4) spot welds postwelding to be spliced, cylinder continue edge rolling on veneer reeling machine, realize
The school circle of major diameter ultra-thin-wall cylinder；(5) shell rolling is completed at the end of the circle of school, first removes cylinder from veneer reeling machine, then by steel
Cord removes from the neck or through hole of axis of traction 2 and whole frock is removed into cylinder.It can be seen that above-mentioned roll traction auxiliary
Process operation is easily and efficiently, it is not necessary to stops rolling the position that can also adjust cylinder, improves operating efficiency, reduces cylinder circle
Error is spent, ensures production safety.
On the basis of above-mentioned frock, to ensure that steady load-bearing rolls sleeve pipe 1, rolling bearing 3 can symmetrically be sleeved on traction
The both sides of axle 2, meanwhile, cause rolling bearing 3 in axis of traction 2 to avoid existing between rolling bearing 3 and spacing ring 5 larger gap
On be axially moveable, can be set between rolling bearing 3 and spacing ring 5 and accept both locating ring 4, the locating ring 4 is optional
Manufactured with steel pipe.
Further, to enable rolling sleeve pipe relatively stable it is sleeved on axis of traction, is cut in the axial direction of the frock
In face (axial direction and the center overlapping of axles of axis of traction 2), the diameter of axis of traction 2 successively decreases at both ends in three layers of step, middle
Maximum gauge section is first layer step, and rolling bearing 3 and locating ring 4 are sequentially located on second layer step, and spacing ring 5 is located at
On three layers of step, the outward flange of the spacing ring 5, which props up, rolls the end of sleeve pipe 1, and spacing ring 5 also has along second layer step upper table
The projection that face is stretched out, the raised front end offset with locating ring 4, ensure stability of the spacing ring 5 on axis of traction 2 with this, and then
It is stable to ensure that limitation rolls the movement of sleeve pipe 1 vertically.
When assembling the frock, the rolling bearing 3 and locating ring 4, Ran Houtao at the both ends of axis of traction 2 can be first assembled by figure
Upper rolling sleeve pipe 1, the spacing ring 5 at both ends is then reassembled, wherein, spacing ring 5 is connected with axis of traction 2 using welding manner, its
His part, which uses, to be flexibly connected.
Certainly, above-mentioned specific configuration settings are only that for example, can also be layered and set without this step, only
The scheme that part with set-up function is assembled according to the utility model essence thinking is all protected in the utility model
In the range of.
