Abstract
The utility model relates to a large-scale hydroelectric power plant overhaul tool, in particular to a vertical type hydroelectric generating set top cover disassembling tool. The vertical type hydroelectric generating set top cover disassembling tool comprises two threaded rods with screw threads at the two ends, wherein a transverse beam is connected between the upper ends of the two threaded rods. A bridge base crossing sleeves and a jack are additionally arranged. The twenty-four sleeves are evenly distributed along the circumference of a top cover, when the vertical type hydroelectric generating set top cover disassembling tool is used, the lower ends of the two threaded rods are connected with the top cover in a screwed mode, the bridge base crossing the top cover is placed, the jack is placed on the bridge base, the jack abuts between the bridge base and the transverse beam, the jack is operated to jack up the transverse beam so as to bring out the sleeves, and the sleeves are brought out one by one to achieve separation between the sleeves and the top cover. The vertical type hydroelectric generating set top cover disassembling tool has the advantages of being simple in structure, simple, practical and good in disassembling effect. A large quantity of manpower and a large number of material resources are saved, labor productivity is greatly improved, the disassembling speed of a set is quickened, good effects are obtained, and the vertical type hydroelectric generating set top cover disassembling tool can be comprehensively popularized in the industry and has wide application prospects.
Description
Technical field
The utility model relates to a kind of large-scale hydraulic power plant service kit, and namely vertical Hydropower Unit top cover decomposes instrument.
Background technology
In the prior art, Component of Hydraulic Turbines all will all be decomposed and hung out, and goes back dress after treatment again.Because Component of Hydraulic Turbines all is positioned at unit lower floor, always decompose at last, return dress at first, so the decomposition of Component of Hydraulic Turbines, processing and time dress speed is determining the maintenance duration of whole unit.And in the Component of Hydraulic Turbines decomposable process, what take time and effort most is exactly the decomposition of water distributor part, and it mainly comprises the decomposition of connecting lever, the decomposition of sleeve and the decomposition of top cover etc.
Want to shorten the maintenance duration of unit, must improve the decomposition rate of these parts, can only improve the decomposition rate of sleeve and top cover.And the top cover decomposition technique that always adopts at present is: decompose sleeve earlier, the handling top cover is decomposed in the back.Adopt not only time-consuming but also consumption power of this kind technology, add that the water wheel chamber working space is narrow and small, personnel's utilization rate is not high, again serious waste human resources.In addition, after top cover was removed, ability handling stator decomposed base ring and labyrinth ring, adopts this kind technology, has incured loss through delay the carrying out of follow-up work, has prolonged the maintenance duration of unit.For this reason, I have proposed a kind of novel top cover decomposition technique and instrument through conscientious research and analysis.
The utility model content
The purpose of this utility model is to provide a kind of at above-mentioned deficiency sleeve and top cover are hung out in the lump, decomposes sleeve again, has simple in structurely, decomposes effective vertical Hydropower Unit top cover and decomposes instrument.
Technical solution of the present utility model is: vertical Hydropower Unit top cover decomposition instrument comprises the screw rod of two two ends band screw threads, is connected with crossbeam between two screw rod upper ends, and other is equipped with bridge chair and the jack of crossing over sleeve.
After the connecting lever decomposition finishes, decompose the handling top cover earlier, sleeve is decomposed in the back.Utilize stator deadweight, stator is separated with sleeve, then sleeve and top cover are hung out in the lump, being transported to behind the space for maintenance again, row decomposes sleeve.Top cover is uniformly distributed with 24 sleeves along the circumference, two screw rod lower ends and top cover is twisted connect, and puts the bridge chair of crossing over top cover, puts jack at bridge chair, jack withstands between bridge chair and the crossbeam, operation jack, jack-up crossbeam, take sleeve out of, operation one by one realizes that sleeve separates with top cover.
The utility model has the advantages that: problems such as 1, new technology has solved when decomposing sleeve in water wheel chamber, and working space is narrow and small, and personnel's utilization rate is low, saved great amount of manpower and material resources, improved labor productivity greatly; Improve the decomposition rate of unit, unit straight line maintenance duration can have been shortened 1 day than traditional handicraft, if calculate with unit unit hour generated energy 100,000 kWh, 0.18 yuan/kWh of rate for incorporation into the power network, can produce 432000 yuan of economic benefits, obtained good effect.Facts have proved, this kind technology be feasible, also be reliable.Novel process, instrument can be used for all vertical Hydropower Unit, in industry popularize in an all-round way, are with a wide range of applications.2, used tool has simple in structurely, simple and practical, decomposes good effectiveness.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Description of drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is Fig. 1 plan structure sketch.
The specific embodiment
Referring to Fig. 1,2, the parts title is as follows: screw rod 1,2, crossbeam 3, sleeve 4, bridge chair 5, jack 6, top cover 7, depression bar 8.
Referring to Fig. 1,2, vertical Hydropower Unit top cover decomposition instrument comprises between the screw rod 1 of two two ends band screw threads, 2, two screw rods 1,2 upper ends and is connected with crossbeam 3 that other is equipped with bridge chair 5 and the jack 6 of crossing over sleeve 4.
During use, two screw rods 1,2 upper ends and crossbeam 3 stubborn connecing, two screw rod lower ends and sleeve 4 stubborn connecing, put the bridge chair 5 of crossing over sleeve 4, put jack 6 at bridge chair 5, jack 6 withstands between bridge chair 5 and the crossbeam 3, operation depression bar 8 moves on the jack 6 jack-up crossbeams 3, takes sleeve 4 out of, operation realizes that all sleeves 4 separate with top cover 7 one by one.
Claims (1)
