Problems solved by technology
Due to the high quality of the sealing plate 93, the risk of manpower moving is relatively high. There are no bolt holes or other structures on the sealing plate 93, which are easy to be hoisted by a general lifting tool, and the anti-rotation teeth and anti-rotation grooves are located between the sealing plate and the anti-rotation groove. In the closed cavity formed by the primary disc, its position is difficult to observe accurately
In the traditional assembly process, the sealing plate is lifted by multiple people, and the positions of the anti-rotation teeth and the anti-rotation slots are observed through the tiny observation hole 933 on the sealing plate (see Figure 4 ), the assembly is more difficult, the assembly cycle is longer, and the labor intensity of the operator is greater

A hoisting device for an interstage sealing disc, which can reduce the risk of manual handling and reduce the difficulty of assembly. Wherein the end of each boom of the base is provided with a short seam for seam positioning with the seam of the interstage sealing disc, each boom is also provided with a claw, the claw has a base and a claw, and the claw has a base and a claw. The end of the protruding boom, the base is slidingly fitted with the boom, so that the distance between the claw and the short notch can be adjusted, thereby allowing the claw to switch between the open state and the closed state. In the closed state, the claw uses When positioning the short spigot and the slit of the interstage sealing disc, buckle the flange side of the interstage sealing disc at the same time, in the open state, the claws can be connected to the flange side of the interstage sealing disc Tripping; the turntable is rotatably set on the base. Multiple connecting rods correspond to multiple claws, one end of each connecting rod is connected to the turntable, and the other end is connected to the base of the claws, so as to convert the rotation of the turntable into the sliding of the base; the locking device is used to unlock the turntable and the base locked tightly.
Description
technical field [0001] The invention relates to a hoisting device for an interstage sealing disc. Background technique [0002] figure 1 The two-stage turbines 92 and 94 shown are installed on the turbine shaft 90, and the sealing between the two is realized by the interstage sealing disc 93, and the sealing disc 93 is connected with the first-stage turbine disc 94 through an interference fit spigot 950 , is connected with the secondary turbine disc 92 through the interference fit spigot 920 . In order to prevent the interstage sealing disk 93 from rotating relative to the turbine disk under the action of thermal deformation and centrifugal force in the working state, a plurality of small-sized anti-rotation teeth are arranged on the interstage sealing disk 93. Correspondingly, the first stage An anti-rotation slot 940 is provided on the turbine disk, and the anti-rotation tooth and the anti-rotation slot need to be aligned during assembly. Due to the high quality of the ...
