Abstract
The invention discloses an on-site gland sealing back-profile milling machine for a turbine. The on-site gland sealing back-profile milling machine comprises a frame base, an operating board, a side upright post, a cantilever, a milling component and a gland sealing clamp, wherein slide rails are arranged on two sides of the frame base; the operating board is connected to the slide rails in a sliding manner; the gland sealing clamp is fixed on the operating board; the side upright post is fixed at one end of the frame base; the cantilever is connected to the upper part of the side upright post in a swinging manner; a horizontal slideway is arranged on the cantilever; the milling component is connected to the cantilever in a sliding manner. During gland sealing field installation of the turbine, if the gland sealing segmental arc is subject to tiny size deviation, the distance between the inner arc and the rotor of the turbine can not meet the design requirement of the clearance, and time and labor are both wasted for depot repair. The on-site gland sealing back-profile milling machine has a simple structure, can realize on-site gland sealing back-profile correction, is very practical and improves the working efficiency.
Description
Technical field
The present invention relates to turbine steam seal production equipment field, be specifically related to the on-the-spot mill of turbine steam seal back of the body arc.
Background technology
In order to reduce the gas leakage of each inter-stage of steam turbine, guarantee again the normal safe operation of steam turbine, therefore the spy is provided with various packings in steam turbine, and whole labyrinth ring is comprised of multistage packing segmental arc.The packing of steam turbine is installed and is generally first carried out scene mapping design, then in process plants, produce multistage packing segmental arc, install on the spot at the scene that finally is transported to, while therefore installing, can run into unavoidably product minimum dimensional discrepancy is arranged, the designing requirement that the inner arc of packing segmental arc and the spacing of turbine rotor do not reach assemblage gap, need to carry on the back arc to packing and carry out the milling correction.If labyrinth casing is returned when repair in shop is corrected errors and delays work, design a kind of equipment that can carry out in erecting bed the correction of packing back of the body arc necessary.
Summary of the invention
The technical problem to be solved in the present invention is to provide the on-the-spot mill of a kind of turbine steam seal back of the body arc, in erecting bed, packing back of the body arc is carried out to accurate milling correction, makes it to meet the designing requirement of assemblage gap, and device structure is simple, practicality.
The present invention is achieved through the following technical solutions:
The on-the-spot mill of turbine steam seal back of the body arc, comprise gantry base, operating desk, heel post, cantilever, milling parts and packing fixture, described gantry base both sides are provided with slide rail, operating desk is slidably connected on slide rail, the packing fixture is fixed on operating desk, and heel post is fixed in gantry base one end, and cantilevered swing is connected to the top of heel post, cantilever is provided with horizontal slide, and the milling parts are slidably connected on cantilever.
The further improvement project of the present invention is, is provided with rotating shaft in the middle of the horizontal slide of described cantilever, and the milling parts are connected in rotating shaft by rocking-arm driving.By rocking arm slip milling parts, adjust the milling cutter horizontal level, operate lighter.
The present invention further improvement project is that described milling parts are provided with the milling cutter height regulating rod.By the milling cutter height regulating rod, adjust the milling cutter height and position.
The present invention further improvement project is, described packing fixture is fan-shaped, and its circle centre position is provided with the fixing hole fixing with operating desk, several locating holes of radially arranging, and the selective assembling of packing locating dowel is wherein.According to the radian of packing segmental arc, the packing locating dowel is installed on to the packing for the treatment of the milling correction in different locating holes in order to location, a sleeve clamp meets the requirement of different size packing, has versatility.
The present invention further improvement project is, also comprises pole bracket, is held on the cantilever below, supports and retrain cantilever.When equipment was not used, pole bracket was held on the cantilever below, plays the effect of an overfill protection cantilever, and during transportation, the constraint cantilever, swing while preventing from transporting.
The present invention compared with prior art, has following obvious advantage:
When steam turbine being carried out to the on-the-spot installation of packing, there is minimum dimensional discrepancy in the packing segmental arc if find, the designing requirement that causes the spacing of its inner arc and turbine rotor not reach assemblage gap, return when repair in shop is corrected errors and delay work, the present invention is simple in structure, can realize the correction of on-the-spot packing back of the body arc, very practical, increase work efficiency.
