Embodiment
Fig. 1 is refer to, the invention provides a kind of side-mounted grading ring, including annulus body 1, rigid connector 4, connection
Bolt 7 and limited support leg 2.In view of the use of grading ring, in order to avoid point discharge phenomenon, annulus body 1, it is rigidly connected
All equal roundings of seamed edge and corner angle of part 4 and connecting bolt 7.Incorporated by reference to referring to figs. 2 and 3 Fig. 2 and Fig. 3 are annulus body 1
Sectional view, in order to show the section view of the fixed plate 3 of different angle on madial wall and limited support leg 2, Fig. 2 and Fig. 3
Angle is different.Fig. 6 is refer to, the madial wall of annulus body 1 welds at least two fixed plates 3, and fixed plate 3 is provided with the first screwed hole
9, the first screwed hole 9 is engaged with connecting bolt 7, and the position of the first screwed hole 9 is less than the lower edge of annulus body 1.In order that
The relatively uniform setting of stress balance fixed plate in, the number and size of fixed plate can be according to the weight and volumes of grading ring
Setting, the present invention are not limited.It refer to Fig. 4, Fig. 4 A, B are respectively the side view and front view of limited support leg 2, stepped ramp type
Horizontal segment it is parallel with annulus body 1, the vertical section of stepped ramp type is 15-20mm beyond the length of the lower edge of annulus body 1.It please tie
Close with reference to figure 5, Fig. 5 A, B, C are respectively the left view, front view and top view of rigid connector 4.Such as figure rigid connector 4 is L
Type, the vertical section of L-type are provided with the second screwed hole 5 coordinated with connecting bolt 7, and the horizontal segment of L-type is provided with mounting hole 6, it is contemplated that
With the welding of aluminium material grading ring, 4 optional aluminium of rigid connector.
For above-mentioned side-mounted grading ring, coordinated designed by the high-tension testing apparatus of cylinder, therefore, of the invention
A kind of installation method is additionally provided, step is as follows：
The first step, installation connecting element：Symmetrical 2 nuts of high-tension testing apparatus top flange are backed out first, will be rigidly connected
Mounting hole 6 on the horizontal segment of part 4 is installed at this 2 points with bolt, the size of rigid connector blue Position Design in accordance with the law, this
Invent without limitation, the aperture of mounting hole 6 blue size design in accordance with the law, common mounting hole pore diameter range is Φ 10- Φ
18。
Second step, place grading ring：Annulus body 1 is sheathed on to the periphery at the top of cylindrical pressure testing equipment 8 so that
The limited support leg 2 of stepped ramp type is connected in cylindrical peripheral side wall, and limited support leg is fixed on the annulus in angular distribution
When on the inside of body, screens effect can be played, still, if larger-size cylindrical pressure experimental facilities, limited support
The number and setting angle of leg can redesign, and the present invention is without limitation.
Then, slewing circle ring body 1 so that fixed plate 3 on the second screwed hole 9 and L-type rigid connector 4 it is vertical
