Description

Guide vanes of water turbine arm extracting tool

Technical field

The utility model relates to Component of Hydraulic Turbines, and more particularly it is a kind of guide vanes of water turbine arm extracting tool.

Background technology

The guide vane lever of turbine gate mechanism connecting lever needs dismounting between turn(a)round, and the method for dismounting usually fixes steel wire rope on guide vane lever, can easily extract with the electric block lifting in water wheel chamber.But due to unit long-play, stator opens and closes for a long time, can there is heavy wear in part guide vane lever and stator upper shaft, adopts that the method for lifting is just very dangerous like this and efficiency is low in the process of dismounting guide vane lever.

Summary of the invention

The purpose of this utility model is the guide vanes of water turbine arm extracting tool a kind of safe and efficient, easy to use carried.

It realizes by following technical scheme:

Guide vanes of water turbine arm extracting tool, comprises stator upper shaft; Described stator upper shaft right-hand member is connected with connecting lever; Described stator upper shaft is also provided with jack; Described jack is provided with circular top plate; Described circular top plate is provided with four top board screws; Described stator upper shaft is fixedly connected with described circular top plate by four screw rods; Described four screw rods are threaded with described circular top plate by four described top board screws; Described circular top plate is provided with the top board set square perpendicular to described circular top plate; Described top board set square is triangular structure, and described top board set square top offers the roof water flat hole of horizontal direction.

The utility model guide vanes of water turbine arm extracting tool obvious especially to the guide vane lever result of use using conventional lifting to be not easy to extract, instrument installing/dismounting simple and fast, operate laborsaving and safety.

In figure: screw rod 1; Circular top plate 2; Top board set square 21; Top board screw 22; Roof water flat hole 23; Jack 3; Connecting lever 4; Stator upper shaft 5.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described in further detail, but this embodiment should not be construed restriction of the present utility model, only for example, simultaneously by illustrating that advantage of the present utility model will become clearly and easy understand.

Guide vanes of water turbine arm extracting tool, comprises stator upper shaft 5; Stator upper shaft 5 right-hand member is connected with connecting lever 4; Stator upper shaft 5 is also provided with jack 3; Jack 3 is provided with circular top plate 2; Circular top plate 2 is provided with four top board screws 22; Stator upper shaft 5 is fixedly connected with circular top plate 2 by four screw rods 1; Four screw rods 1 are threaded with circular top plate 2 by four top board screws 22; Circular top plate 2 is provided with the top board set square 21 perpendicular to circular top plate 2; Top board set square 21 is triangular structure, and top board set square 21 top offers the roof water flat hole 23 of horizontal direction.

Place the mechanical spiral jack 3 of a 50T at stator upper shaft 5 top during use, be that the hole of 4 M30 of the utility model guide vanes of water turbine arm extracting tool and guide vane lever couples together by the M30 screw rod 1 of 500mm again by length, each screw rod 1 is fixed by extracting tool with the 8.8 grade high-strength nuts of two M30, checking tool levelness, then fasten steel wire rope at the top of instrument and be suspended on electric block, in the process of jack stand, steel wire rope remains stress, is finally extracted by guide vane lever always.

It should be noted that: to those of ordinary skill in the art, can also make some changes or distortion to the utility model under the prerequisite not changing the utility model principle, this belongs to protection domain of the present utility model equally.
