Description
Technical field
The present invention relates to steam turbine brush envelope field, particularly a kind of turbine steam seal back of the body arc is repaiied and is scraped device.
Background technology
For steam turbine and gas turbine, in order to improve unit efficiency and to guarantee its safe operation, during overhaul, all to adjust labyrinth clearance.Adjusting labyrinth clearance is meticulous a, hard work.Each combustion gas of the whole nation, thermal power plant mainly adopt in two ways now:
1, artificial scraping: for labyrinth clearance gland blocks bigger than normal, staff on bench vice, manually scrapes off the amount of required adjustment by clip with wooden board on gland blocks pad with scraper, and the gland blocks material of HTHP section is generally all 12CrMoV, and hardness is higher.For the gland blocks of wanting adjustment amount at 0.3-0.5mm, a masterful technique workman one day can only scraping 3-4 piece.And bench vice can make labyrinth clearance inhomogeneous gland blocks folder distortion, cause gland leak-off serious.The machined surface roughness of artificial scraping is poor, is contained in easy bite on conduit, threatens unit safety operation.
2, routine is scraped sealing gland: this device looks for concentricity more difficult, for look for an error at 0.05mm with interior gland blocks, masterful technique workman needs 60 minutes, look for the gland blocks of different-diameter all must be from new adjustment, hand moving knife arm of staff, the feed of another hand, labour intensity is larger, and can process at most 25 every day.
Existing market back of the body arc used machine is all by radius formula cutting back of the body arc, and for diameter packing bigger than normal, conventional back of the body arc machine is too heavy, and size is larger, therefore in each transportation difficulty, and existing back of the body arc machine can only meet the processing of part specification packing, precision is difficult to control, and working ability is limited.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of packing back of the body arc to repair and scrape device, main by adjusting horizontal displacement and vertical displacement, guarantee the cutting accuracy of packing back of the body arc.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
Back of the body arc is repaiied and is scraped a device, it is characterized in that, comprise horizontal adjustment district, vertically adjust district and Bei Huxiugua district, Bei Huxiugua is fixed in district vertical adjustment district, vertically adjusts district and is fixed on horizontal adjustment district; Described horizontal adjustment district comprises horizontal adjustment seat, on horizontal adjustment seat, is fixed with support column; The vertical district that adjusts comprises vertical adjusting seat, and one end and the support column of vertical adjusting seat are fixed, and vertical adjusting seat side is connected with motor fixing plate, adjusts screw rod one end and is connected with motor fixing plate; Bei Huxiugua district comprises motor, and motor is fixed on motor fixing plate, and motor below is provided with base, and base is connected with horizontal adjustment seat, and base is provided with packing fixed leg.
Back of the body arc is repaiied and is scraped a device, it is characterized in that, between horizontal adjustment seat and support column, is bolted; Between motor fixing plate and motor, be bolted.
Back of the body arc is repaiied and is scraped a device, it is characterized in that, described packing fixed leg quantity is more than 3.
Back of the body arc is repaiied and is scraped a device, it is characterized in that, is using state Xia， Bei Huxiugua district also to comprise packing, and packing is fixed on base by packing fixed leg.
Usefulness of the present invention is: 1. by mobile packing cutting back of the body arc, one time turning amount is large, and working (machining) efficiency is high, greatly alleviates operating personnel's labour intensity simultaneously; 2. adopted " bikini location " principle, kept motor to maintain static, by packing fixed leg, found out packing moving track, make operating personnel faster, find the packing center of circle accurately; 3. save back of the body arc machine spiral arm and base plate lot of materials, alleviate back of the body arc machine weight, easy to carry, greatly reduce cost of transportation; 4. can process the packing of arbitrary diameter, can adapt to multi-form gland seal structure and repair and scrape.
