Technical field
The utility model relates to a kind of static equilibrium proving installation, especially relates to a kind of for the statically balanced solid of revolution static equilibrium of testing large solid of revolution proving installation.
Background technology
At present, when solid of revolution being carried out the static equilibrium test, generally be in the center pit of solid of revolution, to assemble rotating shaft and make the two ends of rotating shaft extend solid of revolution, then the two ends with rotating shaft lie on the bracing frame, and solid of revolution is unsettled.If under static state roll, this static equilibrium that this solid of revolution is described is relatively poor, can occur wraparound the rocking of center of turning in the rotation work process, need to adjust solid of revolution.But this mode is also more applicable for the less solid of revolution of diameter, and for several meters even the larger solid of revolution, this mode just is unfavorable for operation for diameter.
The utility model content
Technical problem to be solved in the utility model provides a kind of solid of revolution static equilibrium proving installation, can be beneficial to the static equilibrium test of large revolving body.
The technical scheme that its technical matters that solves the utility model adopts is: solid of revolution static equilibrium proving installation, comprise bracing or strutting arrangement, be provided with at least three stress rods that highly equate at the bracing or strutting arrangement upper surface, described at least three stress rods are distributed on the same circumference, are provided with laser measuring device for measuring on bracing or strutting arrangement or by the bracing or strutting arrangement.
Further be to be provided with backing plate in the upper end of described at least three stress rods.
Further be around bracing or strutting arrangement, to be provided with a plurality of auxiliary supports.
Further be that described a plurality of auxiliary supports are distributed on the same circumference.
Further be around bracing or strutting arrangement, to be provided with a plurality of lifting jack.
Further be that described a plurality of lifting jack are distributed on the same circumference.
The beneficial effects of the utility model are: it not be used in the interior assembling of solid of revolution rotating shaft and carries out the static equilibrium test again, can also whether meet processing request by the size that stress rods intuitively reflects the solid of revolution all directions, can simplify the static equilibrium test job of solid of revolution, reduce the static equilibrium difficulty of test, be particluarly suitable for applying in the static balancing test of large revolving body.
Description of drawings
Fig. 1 is structural representation of the present utility model, and the two-dot chain line of stress rods top is depicted as the solid of revolution that needs test among the figure;
Fig. 2 is the vertical view of Fig. 1.
Be labeled as among the figure: bracing or strutting arrangement 1, stress rods 2, auxiliary supports 3, backing plate 4, lifting jack 5, solid of revolution 6, laser measuring device for measuring 7.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Such as Fig. 1 and shown in Figure 2, solid of revolution static equilibrium proving installation of the present utility model, comprise bracing or strutting arrangement 1, be provided with at least three stress rods 2 that highly equate at bracing or strutting arrangement 1 upper surface, described at least three stress rods 2 are distributed on the same circumference, are provided with laser measuring device for measuring 7 on bracing or strutting arrangement 1 or by the bracing or strutting arrangement 1.Bracing or strutting arrangement 1 is used for supporting the gravity of whole solid of revolution 6, and stress rods 2 is used for measuring solid of revolution 6 at the pressure of all directions.During work, solid of revolution 6 is winched to stress rods 2 tops, and the bottom surface that makes solid of revolution 6 is pressed in stress rods 2 end faces, when the center pit axis of solid of revolution 6 overlaps with circle center's line at stress rods 2 places, solid of revolution 6 will intuitively embody on stress rods 2 at the pressure of all directions counter stress rod 2, thereby know just whether solid of revolution 6 meets the requirements with respect to the size of its center axially bored line in all directions, and then the size of solid of revolution 6 is adjusted so that it meets statically balanced requirement.But, in hoisting process, substantially can not realize the center pit axis of solid of revolution 6 and disposable coincidence of circle center's line at stress rods 2 places, need to carry out adjustment repeatedly, therefore, the setting of laser measuring device for measuring 7, even the center pit axis of solid of revolution 6 did not overlap with circle center's line at stress rods 2 places after lifting was finished, departure between actual apertures center that also can be by laser measuring device for measuring 7 Measurement accuracy solid of revolution 6 and the circle center's line position at stress rods 2 places, then the force value that reflects by stress rods 2 is calculated, the center pit axis that obtains solid of revolution 6 and actual pressure size after circle center's line at stress rods 2 places overlaps, whether also can obtain solid of revolution 6 meets the requirements with respect to the size of its center axially bored line in all directions, therefore, the setting of laser measuring device for measuring 7 can avoid repeatedly adjusting solid of revolution 6, can reduce better static equilibrium test operation difficulty.Present embodiment not be used in solid of revolution 6 interior assembling rotating shafts, can also whether meet processing request by the size that stress rods 2 intuitively reflects solid of revolution 6 all directions, can simplify the static equilibrium test job of solid of revolution 6, reduces the static equilibrium difficulty of test.In the present embodiment, stress rods 2 can arrange more than three, but for better the realization static equilibrium of solid of revolution 6 is tested, and preferably stress rods 2 is set to three.
In the above-described embodiment, in order better solid of revolution 6 to be supported, be provided with backing plate 4 in the upper end of described at least three stress rods 2.Like this, solid of revolution 6 just transfers the pressure on the stress rods 2 by backing plate 4, can avoid in the hoisting process solid of revolution 6 can not prepare to be placed on the stress rods 2.
In hoisting process, when the placement location of solid of revolution 6 is crossed when inclined to one side, turn down from stress rods 2 upsides for preventing solid of revolution 6, around bracing or strutting arrangement 1, be provided with a plurality of auxiliary supports 3.Like this, when rollover occurs solid of revolution 6, can support by 3 pairs of solid of revolution 6 of auxiliary supports, avoid causing security incident.Certainly, these a plurality of auxiliary supports 3 preferably are distributed on the same circumference, in order to better solid of revolution 6 is supported.
In hoisting process, impact for avoiding solid of revolution 6 counter stress rod 2 in transferring process to form, around bracing or strutting arrangement 1, be provided with a plurality of lifting jack 5.Like this, when solid of revolution 6 is transferred from stress rods 2 tops, can be placed into first on the lifting jack 5, and then by the slowly decline of lifting jack 5 solid of revolution 6 be placed on the stress rods 2.In this embodiment, in order to guarantee lifting jack 5 in the decline process, solid of revolution 6 is acted on three stress rods 2 simultaneously, as preferred mode, described a plurality of lifting jack 5 are synchronous hydra-ulic jacks.Like this, in lifting jack 5 decline processes, can make three stress rods 2 bear simultaneously the weight of solid of revolution 6, thereby can avoid unbalance loading crushing stress rod 2.In addition, in the present embodiment, lifting jack 5 can be arranged in arbitrarily around the bracing or strutting arrangement 1, but as optimal way, described a plurality of lifting jack 5 preferably are distributed on the same circumference, are beneficial to better accept the solid of revolution 6 in the process of transferring.
