Description
Technical field
The aid in Pressure Vessel Manufacture Process is the utility model is related to, specially a kind of pressure container cylinder school circle
Frock.
Background technology
When producing large-size cylinder body, such as large-scale storage tank is extremely important to the school circle of cylinder, and the circularity of only cylinder reaches will
Ask, just can guarantee that the quality of product.All trades and professions justify method mainly useful jack school circle to the school of cylinder a few days ago, utilize metal
Performance of expanding with heat and contract with cold carry out school circle, use sufficiently complex, expend many manpower and materials, operating efficiency is relatively low.
The content of the invention
The utility model solves existing school circle method installation, dismounting inconvenience, wastes time and energy, less efficient present situation, carries
For a kind of roll-round tool of pressure vessel cylinder.
The utility model adopts the following technical scheme that realization：
A kind of roll-round tool of pressure vessel cylinder, including central tube, on the outer wall circumference of the central tube it is radial
Cloth is welded with some positioning pipes, and support tube, the support tube end installation school nahlock are fitted with the positioning pipe；The school circle
Block includes top plate, the middle side part welding round steel of the top plate, and the round steel inserts support tube, and the both ends of the top plate are provided with use
In circle screw rod in radially installed school in the mounting hole of fixed welded nut, the nut.
In a state of use, cylinder school sired results installing is placed in pressure container cylinder, and support tube is according to cylinder internal diameter size
From appropriate length and appropriate number of support tube, insert in the positioning pipe of its annulus outer wall, then the round steel of high-ranking officers' nahlock is inserted
Enter and support tube end, adjusting bolt is equal to pressure container cylinder against internal pressure vessel walls, then screw rod end in a diameter
On the circle of internal diameter, reach the purpose of school circle.If internal pressure vessel walls are non-round, then at the non-round position of internal pressure vessel walls,
School circle screw rod stretches out nut length then can be accordingly longer, and survey crew then can conveniently measure.
The utility model has advantages below：
1st, it is simple to operate, school circle efficiency high.
2nd, with dress, avoid carrying out frock making every time because different cylinders are of different sizes.3rd, it is simple in construction, it is easy to
Make.
4th, it is cheap, it is easy to safeguard.
Brief description of the drawings
Fig. 1 represents utility model structural representation.
Fig. 2 represents Fig. 1 partial enlarged drawing.
In figure：1- central tubes, 2- positioning pipes, 3- support tubes, 4- schools nahlock, 5- locating rings, 6- supporting plates, 41- top plates,
42- round steel, 43- nuts, 44- schools circle screw rod.
Embodiment
Specific embodiment of the utility model is described in detail below in conjunction with the accompanying drawings.
A kind of roll-round tool of pressure vessel cylinder, as shown in figure 1, including central tube 1, the outer wall circumference of the central tube 1
Above radially distributed to be welded with 12 positioning pipes 2, i.e., positioning pipe is located in same circumferential plane, and equidistantly distributes in center
Pipe outer wall, support tube 3 is fitted with the positioning pipe 2, and school nahlock 4 is installed in the end of support tube 3.
As shown in Fig. 2 the school nahlock 4 includes top plate 41, the middle side part welding round steel 42 of the top plate 41, the circle
Steel 42 inserts support tube 3, and the both ends of the top plate 41 are provided with the mounting hole for fixing welded nut 43, the internal diameter of nut 43
To installation school circle screw rod 44.
When specifically preparing the cylinder school sired results dress, the size for the pressure container cylinder internal diameter justified according to school, first make one and close
The central tube 1 of suitable diameter, 12 positioning pipes 2 are distributed in the outer wall of central tube 1 and firm welding, separately with 12 root long degree identical branch
Stay tube 3 is one group, makes some groups of different support tubes of length 3, and make 12 school nahlocks 4,41 liang of the top plate of school nahlock 4
The mounting hole for fixing tubular nut 43 is opened at end, the tubular axially middle part of nut 43 is welded at mounting hole, school circle screw rod
44 are radially installed on top plate 41 by above-mentioned nut 43, make 12 pitch circle steel 42, the above-mentioned center weld of round steel 42 is arrived
At the center of top plate 41, top plate 41 is rectangular slab.Then, it is U-shaped ring to make locating ring 5 and supporting plate 6 each one, locating ring 5
（Flat ring）, it is welded on the anchor ring of central tube 1, supporting plate 6 is welded in central tube 1 after being located at locating ring 5 on same diameter line
Anchor ring on.
When carrying out school bowlder to pressure container cylinder, it is adapted to according to cylinder size from one group of long degree, the branch that quantity is suitable
Stay tube 3 is inserted in positioning pipe 2, and same amount of school nahlock 4 is inserted into the end of support tube 3, justifies the position of screw rod 44 by adjusting school
Move, reach the school circle to pressure container cylinder, the school circle screw rod 44 of relevant position is just tightened in the place of adjustment in need.
In order to bear larger stress, school circle screw rod 44 can select suitable length as needed.
As the further improvement filled to school sired results, the support in cylinder school sired results dress includes locating ring 5 and supporting plate 6,
In mounting tool, after horizon rule is inserted into locating ring 5, its bottom is contacted with supporting plate 6, and frock is adjusted by observing horizon rule
Orientation so that school sired results dress axis it is parallel with tubular axis/coincidence.
The utility model has the advantages that：When to cylinder school bowlder, the frock being put into inner barrel, passes through adjusting screw rod
Displacement, reach the school circle to cylinder, the frock is simple to operate, easy for installation, school circle efficiency high, it is most important that repeatable to make
With according to cylinder of different sizes the support tube of different length varying number being selected to carry out school circle, prevent each cylinder school from justifying
Frock, which will be remake, causes the waste of time and material.
Exemplary description is carried out to the utility model above in conjunction with accompanying drawing, it is clear that the utility model concrete implementation is not
Limited by aforesaid way, if the various improvement that methodology and technical scheme of the present utility model are carried out are employed, or not
Improved directly application and other occasions, in the scope of protection of the utility model.
