Accompanying drawing explanation
Fig. 1 is the structural representation of hydraulic turbine air admission valve of the present utility model dismounting special hanger.
Detailed description of the invention
Below in conjunction with preferred embodiment and accompanying drawing thereof, technical solutions of the utility model are further non-limitingly described in detail.
Dismounting special hanger of the present utility model is for hydraulic turbine air admission valve, for air admission valve is hung out maintenance or hangs in back dress from water-turbine top cover, owing to water-turbine top cover and air admission valve have specific shape and structure, therefore, the shape and structure of dismounting special hanger of the present utility model needs to match with actual condition, is otherwise difficult to organize work.
Concrete condition is with reference to shown in Fig. 1:
Dismounting special hanger is with support bar 1 for trunk, and in the present embodiment, support bar 1 adopts stainless steel, cylindrical, its hardness, durability degree and price substantially conform to requirement, certainly also can be selected for the material that other cost performances are higher, support bar 1 is of a size of: long 2070mm, diameter of section 46mm.
A piece connecting rod 2 of fixing connection on the top of support bar 1, wherein one end of connecting rod 2 interfixes with the top of support bar 1 and welds, and connecting rod 2 is perpendicular with support bar 1, and in the present embodiment, connecting rod 2 is the iron bar of thick 16mm, long 365mm；The other end one suspension ring 3 of welding of connecting rod 2, suspension ring 3 are positioned at the lower section of connecting rod 2, and in the present embodiment, suspension ring 3 are M42 nut.
For ensureing that connecting rod 2 and support bar 1 have firm connection, being welded with first girth member 10 in the junction of connecting rod 2 with support bar 1, this first girth member 10 is the iron bar of thick 16mm, long 95mm；Simultaneously, also has the second girth member 20, this second girth member 20 is iron bar equally, wherein one end is welded with connecting rod 2, pad is near suspension ring 3, and the other end welds with support bar 1, and pad and support bar 1 top are apart from about 340mm, support bar 1, connecting rod 2 and the second girth member 20 form a triangle so that connecting rod 2 has stable support.
Weld a sleeve 4 in the lower end of support bar 1, the model of this sleeve is M65, and length is 55mm.Weld an inserted link 5 in the lower end of sleeve 4, this inserted link 5 model is M24, and length is the screw rod of 110mm.
At one piece of connecting plate 6 of lower weld of support bar 1, this connecting plate 6 is positioned at the top of sleeve 4, and with connecting rod 2 homonymy, in the present embodiment, connecting plate 6 is one piece of iron plate, and it is of a size of: long 115mm, wide 75mm, thick 8mm.Bottom outside connecting plate 6, welding balance element 7, this balance element 7 height adjustable, is used for adapting to different operating mode, in the present embodiment, balance element 7 includes a two nut 7a and screw rod 7b, the model of nut 7a is all M36, and the model of screw rod 7b is M36, and screw rod 7b can be threadeded mutually with nut 7a, by rotary screw 7b, may be height adjusted.
Use dismounting special hanger of the present utility model dismounting air admission valve flow process approximately as:
1) the break pin hole on a guide vane arm near air admission valve is utilized; the inserted link 5 of support bar 1 lower end is inserted in the hole (performing protection with copper sheet) of this break pin; because the practical situation of every unit is different; connecting lever break pin hole or connecting lever surface height are not quite similar; therefore the height of screw rod 7b should be adjusted according to practical situation, until support bar 1 VE is this.
2) in suspension ring 3, buckle the shackle (not shown) fulcrum as 1T hoist of a 2T, then the hoist of 1T is hung up, adjust direction, make hoist be in the top of air admission valve, after hanging up properly destructive valve, pull hoist to be lifted by air admission valve.
3) after certain altitude sling by air admission valve (bottom exceedes pedal or connecting lever, and inspection is repaiied the needs of situation and determined), it is possible to artificially put destructive valve to relevant position, pine is except starting upkeep operation after hoist.
The direction that dismounting special hanger of the present utility model adjusts specific purpose tool when returning dress air admission valve according to practical situation can use.
