Abstract
The utility model provides a specialized tool is installed and removed to impulse unit runner, wide application in the new tool structure of impulse unit runner loading and unloading. Runner lift servomotor piston is arranged at the hydraulic turbine alignment of shafts downtheholely, utilizes the promotion of runner lift servomotor piston rod to install and dismantle the runner with descending. The utility model discloses utilize hydraulic turbine alignment of shafts hole, runner lift servomotor is arranged wherein, does not occupy other spaces, the runner is between the turn(a)round simultaneously, and when needing to dismantle the runner, the outside oil sources that removes of switch -on just can convenient be dismantled the runner, does not need extra other instruments, and is convenient, high -efficient, the utility model discloses simple structure, safety, high efficiency are easily promoted, in can extensively applying to the runner installation of impulse turbine group and dismantling.
Description
Technical field: the utility model relates to a kind of novel rotating wheel assembly and Disassembly special tool structure.
Background technology: the head of impulse turbine is usually higher, more than 200 meters, most high water head 1800 meters at present, runner subjects the enormous impact power of current, under this severe service condition, runner needs regularly to carry out inspection and maintenance, needs to carry out repair welding to damage location, polishing, the operations such as flaw detection, spraying, now runner needs to disassemble from main shaft, after waiting maintenance qualified, being returned by runner installs on main shaft again, and dismounting and installation runner all need to use specific purpose tool.Often adopt the several stock hydraulic relay device in 2-3m place below runner at present, be temporarily fixed on travelling bogie, servomotor is utilized to be elevated mounting or dismounting runner, installment and debugging stock hydraulic relay device and fluid pressure line is all needed before mounting or dismounting runner, mounting or dismounting runner efficiency is low, also dangerous, in order to shorten the runner mounting or dismounting time, design safety, efficient, practical specific purpose tool just seem particularly important.
Summary of the invention: the purpose of this utility model is to provide the new tool structure that a kind of specific purpose tool can installing and removing runner is widely used in runners of impulse turbine handling.The purpose of this utility model is achieved through the following technical solutions: overall is vertical structure, runner lifting servomotor piston (1) is arranged in hydraulic turbine main shaft (2) centre bore, end face seal lid (3) is connected with hydraulic turbine main shaft (2) by the first bolt (4), oil pocket is formed between runner lifting servomotor piston (1) and end face seal lid (3), end face seal lid (3) is provided with into, flowline interface, piston rod (5) end arranges pallet (6), pallet (6) is connected with piston rod (5) and runner (9) with the second bolt (8) respectively by nut (7).
The utility model advantage is: 1) utilize hydraulic turbine main shaft centre bore, and runner lifting servomotor is arranged wherein, does not take flow channel space; 2) between runner turn(a)round, when needing dismounting runner, connect outside mobile oil sources, just can conveniently dismantle runner, do not need other instrument extra, convenient, efficient; 3) structure simply, safely, efficiently, is easy to promote, and can extensively apply in the installation and removal of impulse water wheel unit runner.
Accompanying drawing illustrates:
Fig. 1 is the overall structure of the utility model specific purpose tool.
Detailed description of the invention:
The runner that a kind of impulse turbine uses as shown in Figure 1 is installed, tool special for dismounting structure.Runner lifting servomotor piston 1 is arranged in hydraulic turbine main shaft 2 centre bore, end face seal lid 3 is connected with hydraulic turbine main shaft 2 by bolt 4, oil pocket is formed between piston 1 and end face seal lid 3, end face seal lid 3 is provided with turnover tubing interface, piston rod 5 end arranges pallet 6, and pallet 6 is connected with piston rod 5 and runner 9 with bolt 8 respectively by nut 7.
Between runner turn(a)round, when needing dismounting runner, connect outside mobile oil sources, utilize the lifting of lifting servomotor piston rod and decline to mount and dismount runner, do not need other instrument extra, improve installation effectiveness.
This new tool structure is simple, compact, be easy to operation, is beneficial to the runner assembly and Disassembly special tool application of spindle hole design and promotes.
