Problems solved by technology

Since the gap between the two blades is smaller than the width of the sealing piece, and at the same time, the interference fit between the positioning pin and the turbine casing is difficult to disassemble, making it difficult to install the sealing piece. This problem also exists when replacing the turbine stator blades in the later stage. Therefore, it is necessary to design An installation device to solve the installation problem of sealing sheet

Abstract

The invention relates to a device, in particular to a packing-off piece installation device of turbine stator blades and a use method of the packing-off piece installation device. According to the technical scheme, the packing-off piece installation device comprises an installation plate, an installation edge, first screws, balancing weights, limiting blocks, second screws, fixing bolts and nuts; the installation plate is a semicircular plate and is provided with two end plates and an auxiliary plate on the top of the arc; first installation holes are formed in the semicircular plate, the interval of the first installation holes is the same as the interval of end holes of the two turbine stator blades, and hoisting holes are formed in the end plates and the auxiliary plate; the balancing weights are fixedly arranged on the end plates, and the limiting blocks are arranged on the end plates through the second screws; the installation edge is in a semicircular shape and provided with second installation holes; the installation plate and the installation edge are connected together through the first screws, and the positions of the first installation holes correspond to the positions of the second installation holes; and the fixing bolts and the nuts are used for fixing the turbine stator blades. By means of the packing-off piece installation device, installation of packing-off pieces is achieved under the condition that positioning pins of the turbine stator blades are not decomposed.

Description

technical field [0001] The invention relates to a device, in particular to a turbine stator vane sealing piece installation device and a usage method thereof. Background technique [0002] In the gas turbine structure, the installation of sealing sheets between the turbine stator blades is an important means to ensure the efficiency of the gas turbine. There is an existing gas turbine turbine structure, the casing of which is a horizontal split structure, the stator blades are positioned circumferentially by positioning pins, axially positioned by retaining rings, radially positioned by outer ring blocks, and fixed by inner ring blocks on the stator blade. During the machining process of the turbine case, the outer ring block and the inner ring block need to be installed on the casing to combine and process the honeycomb size. Therefore, the positioning pins and the stator blades need to be installed in place first. After combined processing, the inner and outer ring blocks...
