Description
Technical Field
The utility model belongs to the field of tool clamps, and particularly relates to a power turbine guide installation device.
Background
The power turbine is of an axial flow type structure and is divided into two-stage and four-stage turbine structures. The two-stage turbine structure consists of a 3 rd-stage guider, a 4 th-stage guider, a guider transition section, a power turbine rotor and a power turbine supporting ring; the four-stage turbine structure consists of a 3 rd stage guide, 4 th to 6 th stage guides, a power turbine rotor and a power turbine support ring. The power turbine is used for driving power consumption equipment, and is assembled with the low-pressure turbine supporting ring in a butt joint way through the front flange of the outer casing of the 3 rd-stage guider and the front flange of the adapter cylinder, so that the whole gas turbine is formed. The existing equipment has the problems that the suspended assembly of parts has no supporting point, the centering is difficult and the like.
Disclosure of Invention
The utility model aims at providing a power turbine guide installation device which has special part structure of 4 th-6 th level guides, is free of supporting points in part suspension assembly and has difficult centering problem in each level of guide assembly.
A power turbine guide mounting device comprising: the centering device comprises a centering plate A, a supporting plate A, a centering plate B, a supporting plate B, a mandrel, a short sleeve, a long sleeve, a bolt and a centering plate C; the mandrel is fixed on the support plate B through bolts; the centering plate A is arranged at the upper end of the supporting plate B through a bolt; the upper end of the centering plate A is provided with a long sleeve and a centering plate B; the upper end of the centering plate B is provided with a supporting plate A, and the upper end of the supporting plate A is provided with a short sleeve and a centering plate C.
Furthermore, the centering plates A, B and C are provided with rabbets for fixing the guides at all levels through the rabbets, so that the radial centering effect on the guides at all levels is achieved.
Further, the centering plates A, B and C are welded structures.
The utility model has the beneficial effects that:
the utility model not only can solve the problems of no supporting point in the suspended assembly of parts and difficult assembly and centering of each level of guide, but also omits the assembly preparation work of operators for adjusting the axial size and the position of the guide by a jack, and has the characteristics of convenient use, simple operation and improvement of assembly efficiency.
