Abstract
The utility model provides a tool for measuring radiation deviation in a process of assembling locking plate groove type blades of a turbine rotor, relating to a tool for measuring the radiation deviation in the process of assembling the blades. With the adoption of the tool provided by the utility model, the problems that the conventional radiation deviation measuring tool cannot ensure the measurement precision, is inconvenient to measure, and cannot realize radiation deviation measurement of penultimate stage blades of a large-scale low-pressure rotor can be solved. A base comprises a main board and two edge boards; the two edge boards are respectively arranged at the front side and the back side of the main board; two cylindrical pins are mounted on the bottom face of each edge board; an L-shaped bracket is mounted on the upper end face of the main board; a positioning pin is mounted on the left lateral face of the main board; a dial indicator is mounted on a stand board of the L-shaped bracket; and the top point of a meter head of the dial indicator and the top point of the positioning pin are located on the same vertical line. The tool provided by the utility model is used for measuring the radiation deviation in the process of assembling the locking plate groove type blades of the turbine rotor.
Description
Technical field
The utility model relates to a kind of turbine rotor blade assembling radiant rays deviation survey instrument, is specifically related to a kind of turbine rotor locking plate slot type blade assembling radiant rays deviation survey instrument.
Background technology
The radiant rays deviation of spinner blade assembling directly has influence on the through-flow parameter of steam passage of blade, and through-flow parameter is with the generated output that has influence on unit between straight.This just requires in the blade assembling process must strictness to control well blade radiant rays deviation, could guarantee the accuracy of blade rigging position, makes blade when unit operation, can be in correct working position.The high-power unit of steam turbine product more than 600,000; The second last stage blade of low pressure rotor adopts the blade locking mode of locking plate groove structure more; Mostly this structure impeller wheel face is the inclined-plane; And two impellers are opened shelves bottoms cylindrical and the wheel face cylindrical differs bigger, and generally about 800mm, and mostly blade is the blade of 530mm.The blade assembling process; If adopt traditional radiant rays measuring method; The radiant rays measurer of design is positioned at two impellers and opens on the cylindrical of shelves bottom; The measurer gauge head will stretch out millimeters long more than 100 and could contact with the blade root intermedium, and measurer top gauge outfit will be stretched out more than 100 millimeter long dozen on blade shroud, and the measuring stent length is wanted about 1 meter.Measurer self precision can't guarantee that at all the too big workman of measurer also can't carry out work by hand simultaneously, and the low pressure rotor second last stage blade radiant rays deviation of high-power unit adopts conventional gauges to measure, and can't guarantee measuring accuracy, and is not easy to measure.
The utility model content
The purpose of the utility model is to exist heavy in order to solve existing radiant rays deviation survey instrument; Can't guarantee measuring accuracy; And be not easy to problems of measurement; And can't realize large-scale low pressure rotor second last stage blade radiant rays deviation problems of measurement, and then a kind of turbine rotor locking plate slot type blade assembling radiant rays deviation survey instrument is provided.
The technical scheme of the utility model is: turbine rotor locking plate slot type blade assembling radiant rays deviation survey instrument comprises dial gauge, L type support, register pin, base and four straight pins; Base comprises mainboard and two side plates; The both sides, front and back of mainboard respectively are provided with a side plate; Two straight pins are installed on the bottom surface of each side plate, and L type support is installed on the upper surface of mainboard, on the left surface of mainboard register pin is installed; On the riser of L type support dial gauge is installed, the gauge outfit summit of dial gauge and the summit of register pin are on same vertical curve.
The utility model compared with prior art has following effect: the survey instrument of the utility model utilizes the positioning supports of the locking plate groove periphery of impeller both sides as measurer; On the impeller wheel face that survey instrument is ridden over, the gauge head of survey instrument is short, the top of survey instrument and vane tip height basically identical; Survey instrument length is controlled in the 550mm; Greatly reduce length measured, improve the precision of survey instrument self, the gauge head of survey instrument directly drops on the blade measuring point; Improve measuring accuracy, the weight of survey instrument is urinated and is used in the workman.The survey instrument of the utility model is accurately controlled the radiant rays deviation of blade assembling; Solved large-scale low pressure rotor second last stage blade radiant rays deviation problems of measurement; Guaranteed to be in correct working position after the blade assembling; Make blade when unit operation, be in correct working position, improve unit generation efficient.
