Abstract
The utility model relates to an auxiliary support device of gas turbines, including a base, an upper connecting rod and lower connecting rod and auxiliary support base; mainly, said upper connecting rod and the lower connecting rod are provided with a radial spherical plain bearing and both ends are provided with positive and negative double-helical rod, and said auxiliary support is provided with a disc spring. The center height of the auxiliary support device of gas turbines of the utility model can be easily adjusted, with little thermal absorption expansion and reduction and blocking vibration functions, ensuring the simplicity of the center height and the level adjustment in the installation process of gas turbines, eliminating the adverse effects on gas turbines resulting from thermal expansion in the different directions in the use process of the units, and meanwhile reducing effectively the vibration of gas turbines, and blocking the transmission of the vibration among gas turbines and other parts of the units.
Description
Technical field
The utility model relates to a kind of gas turbine auxiliary support apparatus, belongs to the engineering class.
Background technique
Gas turbine needs support device to support when using on ground, to guarantee normal use.Usually load such as the main weight of gas turbine, output torque are born by main the support; Supplemental support is born partly gas turbine weight, is reduced the moment of flexure on main the support, and adapts to the cold and hot variation in the gas turbine using process and reduce and intercept vibration.
Original auxiliary support structure is comparatively complicated, and it is inconvenient that its shortcoming is that the gas turbine center height is adjusted, and the thermal expansion that can only adapt to the axial direction of gas turbine changes, and can not adapt to it and radially change with the thermal expansion of Vertical direction.Original besides supplemental support is a rigid support, can not lower vibration and blocking-up transfer of vibration effectively.
Summary of the invention
The utility model is in order to overcome the shortcoming that prior art exists, and it is easy to adjust to have proposed a kind of center height, has the absorption thermal expansion, reduces, intercepts the support device of vibration function.
The utility model is to realize above-mentioned purpose like this.
Include base, last connecting rod and lower link, the supplemental support seat, main feature is that described upward connecting rod and lower link are provided with plain radial bearing, two ends are positive and negative double helix bar, establish belleville spring on the described supplemental support seat.
Gas turbine auxiliary support apparatus of the present utility model, center height is easy to adjust, has the function that absorbs thermal expansion and reduce, intercept vibration, both guaranteed the simplification of center height and horizontal adjustemt in the gas turbine installation process, eliminated the adverse effect that all directions thermal expansion causes gas turbine in the unit using process, transfer of vibration between other each part of gas turbine and unit has been blocked in the vibration of having lowered gas turbine effectively simultaneously.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the left view of the utility model structure.
Fig. 3 is the I part enlarged view among Fig. 2.
Among the figure: connecting rod 4 double helix bars 5 lower links on 1 gas turbine, 2 plain radial bearings 3,6 pins, 7 supplemental support seats, 8 guide spiro rods, 9 belleville springs, 10 bases.
Embodiment
By Fig. 1, Fig. 2 and Fig. 3 as can be seen, the utility model is to be provided with supplemental support seat 7 on base 10, and last connecting rod 3 and lower link 5 are provided with plain radial bearing 2, and two ends are positive and negative double helix bar 4, establish belleville spring 9 on supplemental support seat 7.Because the use of upper and lower each two plain radial bearing 2 makes joining with it upward connecting rod 3 and lower link 5 can do the rotation motion of several angle around pin 6, to adapt to the radial deformation that the gas turbine thermal expansion causes; And the beat that can make several angle in supplemental support seat 7 moves, to adapt to the axial linear distortion that gas turbine 1 thermal expansion causes, make gas turbine 1 be in state relatively freely on axial direction, the normal temperature state all can move down and under the working state unfetteredly.Gas turbine 1 only bears the load of Vertical direction on supplemental support point, and not because thermal expansion makes gas turbine bear other power or moment.Can regulate the height at gas turbine center easily by the length of regulating auxiliary support bar, guarantee that gas turbine is in level, avoid bearing extra moment of flexure because of the assembly quality problem supports the gas turbine master.The upper and lower some groups of belleville springs 9 of respectively having installed of supplemental support seat 7; make supplemental support seat 7 can be installed in guide spiro rod 8 on the base 10 like this and move up and down the Δ h (thermal expansion amount of Δ h＞Vertical direction+gas turbine vibration values+by the driven equipment vibration values in the effect lower edge of belleville spring; the size of Δ h value has also determined what of group number of belleville spring); make gas turbine 1 in supplemental support everywhere in a kind of flexible support state; to support, to protect gas turbine effectively and to absorb vibrational loading, avoid the mutual transmission of vibrating.
