the utility model provides a steam turbine main throttle pipe support, includes the support body, the equal fixed mounting in four angle departments at the top of support body has hoist and mount piece, the clamp is installed to the bottom of support body, the clamp includes the clamp body, lower clamp body, go up the clamp body and clamp body detachable connects down, go up the top of the clamp body and install the fixing base, fixing base and support body fixed connection.

The hoisting piece comprises a guide cylinder fixedly connected with the frame body, a guide post is installed in the guide cylinder, and a spring is installed between the guide post and the guide cylinder.

The outer diameter of the guide post is smaller than the inner diameter of the guide cylinder, the limiting block is fixedly installed at the bottom end of the guide post, the outer diameter of the limiting block is matched with the inner diameter of the guide cylinder, a limiting ring is fixedly welded to the top of the guide cylinder, the spring is sleeved outside the guide post, one end of the spring is abutted to the limiting block, and the other end of the spring is abutted to the limiting ring.

And a second flange is installed at the bottom of the guide cylinder and is matched with a stud fixedly installed at the top of the frame body.

And a first flange is fixedly arranged at the top end of the guide column.

The clamp has two, installs respectively at the both ends of support body.

The utility model has the following technical effects

The utility model discloses an install the spring in the hoist and mount subassembly, can play certain cushioning effect, take place to shake when the pipeline and can cushion, still install the rubber pad on the clamp, prevent that the pipeline from taking place the damage, this support is held the pipeline simultaneously and is reduced the pulling force of pipeline gravity to steam turbine main throttle department flange.

Detailed Description

The following are only embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.

In the present invention, the words describing the directional relationship such as "front", "back", "inner", "outer" are only used for convenience of description of the embodiment, and are not considered as limitations of the present invention. The terms "first," "second," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance. The fixed connection or installation mode includes but is not limited to welding, spiro union, joint, interference fit, integrated into one piece.

Fig. 1 to 3 show an embodiment of the present invention. This embodiment provides a steam turbine main throttle pipe support, including support body 1, there is hoist and mount piece at four equal fixed mounting in angle departments at the top of support body 1 for install support body 1 on steam turbine mounting platform, a pair of clamp 8 is installed to the bottom of support body 1, is used for fixed main throttle pipe.

The hoisting piece comprises a guide cylinder 3, a second flange 7 is installed at the bottom of the guide cylinder 3, and the second flange 7 is matched with a stud 2 fixedly installed at the top of the frame body 1. Install guide post 6 in guide cylinder 3, the external diameter of guide post 6 is less than the internal diameter of guide cylinder 3, at the bottom fixed mounting stopper 10 of guide post 6, the external diameter of stopper 10 and the internal diameter phase-match of guide cylinder 3, the top welded fastening of guide cylinder 3 has stopper ring 4, prevents 6 slippage of guide post, and the top fixed mounting of guide post 6 has first flange 5 for fix whole device in steam turbine mounting platform's bottom. Install spring 9 between spacing ring 4 and stopper 10, spring 9 covers outside guide post 6 promptly, and one end offsets with stopper 10, and the other end offsets with spacing ring 4.

Two clamps 8 are installed respectively at the both ends of support body 1, and clamp 8 includes the clamp body 8.1, down the clamp body 8.3, goes up clamp body 8.1 and down clamp body 8.3 and is the semicircle ring-type, and the two is connected through the engaging lug cooperation bolt detachable at both ends.
