Description
Technical field
The utility model relates to Francis turbine field, tears structure open under particularly relating to a kind of vertical unit runner.
Background technology
Francis turbine is a kind of existing hydro-electric power generating equipment, and its primary structure comprises main shaft, being arranged at below main shaft for connecting the ring flange of runner, being connected to the runner on ring flange, the pouring mechanism that arrange corresponding to runner.Be wherein directly connect as one by Li Anie bolt between ring flange and runner, when runner needs maintenance or replaces, just need to carry out removing and installing of runner.
At present, when needs dismounting runner, generally have two kinds of modes, the first is that runner and main shaft entirety upwards hang out by the rear use drivings such as dismounting generator, main shaft seal, water pilot bearing; The second way is dismantled with ring flange by runner after runner and main shaft entirety being winched to after removing main shaft seal, water pilot bearing the safe ground below runner downwards to separate again, then process runner.After handling well, be also first after runner and spindle flange dish first assemble by safe ground, then integral lifting is installed to installation site.In the prior art, the directly handling separately to runner cannot be realized, this mainly because the location that cannot realize when directly installing between runner and spindle flange dish and fastening at narrow space place to runner connecting bolt, cannot solve the problem of the potential safety hazard of operating personnel simultaneously.And after hanging under runner and spindle flange are checked and regulated body, realize the dismounting between runner and spindle flange dish and installation on the ground, just there is not the problem cannot located with potential safety hazard.But, so very inconvenience and add the mounting or dismounting cost of runner greatly.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, structure is torn open under providing a kind of vertical unit runner, the utility model the utility model has running cost ground, saves operating time, advantage that security is good, and can not have influence on the installation quality of fit of main shaft self because of dismounting runner.
The technical solution of the utility model is: tear structure open under a kind of vertical unit runner, comprise main shaft, runner, sleeve, saddle, ring flange, alignment pin, dowel hole, mounting or dismounting screw rod and nut, it is characterized in that: below described main shaft, be provided with runner, main shaft and runner corresponding position are provided with sleeve, sleeve and runner are mutually permanently connected, described sleeve inner ring is provided with detachable saddle, described ring flange is arranged on main shaft, ring flange and main shaft are mutually permanently connected, ring flange lower end surface is provided with the alignment pin be mated and the dowel hole mated, described mounting or dismounting screw rod is arranged at ring flange lower end surface, mounting or dismounting screw rod lower end is provided with detachable nut, nut is rotatably connected mutually with mounting or dismounting screw rod.
The beneficial effects of the utility model are: tear structure open under a kind of vertical unit runner, comprise main shaft, runner, sleeve, saddle, ring flange, alignment pin, dowel hole, mounting or dismounting screw rod and nut, it is characterized in that: below described main shaft, runner corresponding position is provided with sleeve, sleeve inner ring is provided with detachable saddle, described ring flange is arranged on main shaft, ring flange lower end surface is provided with the alignment pin be mated and the dowel hole mated, described mounting or dismounting screw rod is arranged at ring flange lower end surface, mounting or dismounting screw rod lower end is provided with detachable nut, nut is rotatably connected mutually with mounting or dismounting screw rod.The utility model has running cost ground, saves operating time, advantage that security is good, and can not have influence on the installation quality of fit of main shaft self because of dismounting runner.
