Embodiment Construction

[0017] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] like figure 1 As shown, the structure of this embodiment includes a bearing support plate 301, a fixed block 101, a cylinder connector 201 and a horizontal pin. The fixed block 101 is fixed on the bearing support plate 301, and one end of the cylinder connector 201 is fixedly connected to the cylinder. , the other end is a U-shaped fork structure, the fixed block 101 is arranged in the U-shaped fork, a through hole 1021 is provided on each side of the U-shaped fork, the two through holes are coaxial, and the positions corresponding to the two through holes on the fixed block 101 A coaxial through hole is also provided, and the horizontal pin 102 is passed through the through hole to connect the U-shaped fork with the fixed block 101 .

[0019] In this embodiment, the bearing seat support plate 301 is integrated with the steam turbine bearing se...

Abstract

The invention provides a novel cat claw structure used for a small steam turbine. Connection of a steam cylinder and a bearing seat is achieved, the structure is novel, it can be effectively guaranteed that the relative positions of the steam cylinder and the bearing seat are not changed, and meanwhile the smooth free expansion of the steam cylinder is guaranteed. According to the technical scheme, the novel cat claw structure comprises a bearing seat supporting plate, a fixed block, a steam cylinder connecting piece and a transverse pin; and the fixed block is fixed to the bearing seat supporting plate, one end of the steam cylinder connecting piece is fixedly connected with the steam cylinder, the other end of the steam cylinder connecting piece is of a U-shaped fork structure, the fixedblock is arranged in the U-shaped fork, the two sides of the U-shaped fork are each provided with a through hole, the two through holes are coaxial, coaxial through holes are also formed in the positions, corresponding to the two through holes, of the fixed block, the transverse pin is arranged in the through holes in a penetrating manner, and therefore the U-shaped fork is connected with the fixed block.

Description

technical field [0001] The invention relates to a steam turbine cylinder support device, in particular to a novel cat's claw structure for a small steam turbine. Background technique [0002] On steam turbines, in order to ensure that the cylinder can expand freely after being heated, and the relative expansion difference between the dynamic and static parts does not exceed the allowable value, the cat claw structure used for supporting and positioning on the cylinder is a key structure in the design of the unit. [0003] The support of the cylinder is on the base plate, and the base plate is fixed on the foundation with anchor bolts. There are generally two ways to support the cylinder: one is that the cylinder is supported on the bearing seat through the cat claw structure, and placed on the platen through the bearing seat; the other is directly placed on the platen with the outstretched legs. [0004] The cat claws that extend forward and backward from the horizontal fla...
