Description
Technical field
This utility model relates to a kind of wind turbine gearbox pipe axle scotch and damages maintenance unit, belongs to wind generating technology neck
Territory.
Background technology
In cabin, the block junction such as generator tube axle with planet carrier loosens, and gear-box pipe axle and main shaft and planet carrier are not
Energy synchronous rotary, ultimately results in gear-box pitch control cable and the asynchronous rotation of pipe axle, twists off cable；Maintenance pipe axle cannot be straight
Connect the gear-box of extraction to be required for hanging complete machine and solve；Old way in the past, is not only affected greatly by weather, and the cost keeped in repair is very
Greatly, and cause shutdown, impact generating.The expense transported without electric quantity loss etc., light lifting cost is general with the cost of 1 gear-box
About 200,000.Plus transport, returning factory's expense, also electric quantity loss will be about 300,000.
Cause this reason main, relevant with limited space in cabin and gear box structure.Cannot directly take out for pipe axle
The gear-box gone out, pipe axle cannot keep in repair with planet carrier junction, be necessary for by increase similar pipe axle construction again by pipe axle with
Become oar cable, planet carrier, main shaft connect such that it is able to allow pipe axle and main shaft synchronous rotary.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of wind turbine gearbox pipe axle scotch and damages maintenance unit,
This wind turbine gearbox pipe axle scotch damage maintenance unit solves gear-box pipe axle can not synchronous rotary with main shaft and planet carrier
Thus ultimately result in gear-box pitch control cable and the asynchronous rotation of pipe axle, twist off cable and maintenance of equipment time length and expense
By big problem.
In order to solve above-mentioned technical problem, a kind of wind turbine gearbox pipe axle scotch of the present utility model damages maintenance unit
The conduit that is connected including some joints, the first flange, the second flange, the conduit that described some joints are connected runs through and is arranged on gear-box
In the main shaft of pipe axle and blower fan, described pipe axle outer end connects the first flange, and main shaft outer end connects the second flange, described first method
Blue, the second flange is all threadeded with conduit.
It is threaded connection between described often joint conduit.
Described first flange is all bolted to connection with main shaft with pipe axle and the second flange.
Described conduit is aluminum pipe.
After this utility model uses said structure and method, have the advantage that
The conduit being connected due to some joints runs through in the main shaft of pipe axle and the blower fan being arranged on gear-box, described pipe axle outer end
Connecting the first flange, main shaft outer end connects the second flange, and described first flange, the second flange are all threadeded with conduit, thus
Pipe axle is linked together with main shaft by conduit, it is achieved synchronous rotary, such treating method solve gear-box pipe axle with
Main shaft and planet carrier can not synchronous rotary thus ultimately result in gear-box pitch control cable and the asynchronous rotation of pipe axle, twist off electricity
Cable, and use this maintenance unit reduce the original maintenance cost of equipment and shorten original maintenance time.
Accompanying drawing explanation
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Wherein have: 1, the first flange, 2, bolt, 3, pipe axle, 4, conduit, the 5, second flange, 6, main shaft.
Detailed description of the invention
Shown in Fig. 1, a kind of wind turbine gearbox pipe axle scotch damages maintenance unit, the conduit 3 that is connected including some joints, the
One flange the 1, second flange 5, the conduit 4 that described some joints are connected runs through the main shaft 6 of pipe the axle 3 and blower fan being arranged on gear-box
In, described pipe axle 3 outer end connects the first flange 1, and main shaft 6 outer end connects the second flange 5, described first flange the 1, second flange 5
All threaded with conduit 4.
It is threaded connection between described often joint conduit 4.
Described first flange 1 is all connected by bolt 2 is fixing with main shaft 6 with pipe axle 3 and the second flange 5.
Described conduit 4 is aluminum pipe.
A kind of wind turbine gearbox pipe axle scotch damages the installation method of maintenance unit, and the method comprises the following steps:
Some joint conduit 4 screw threads are docked, the conduit 4 connected will run through pipe axle 3 He being arranged on gear-box by step one
In the main shaft 6 of blower fan；
Step 2, connects the first flange 1 in pipe axle 3 outer end by bolt 2, runs through the one of the pipe axle 3 being arranged on gear-box
The conduit 4 of end is connected with the first flange 1；
Step 3, connects the second flange 5 in main shaft 6 outer end by bolt 2, runs through the one end of the main shaft 6 being arranged on blower fan
Conduit 4 be connected with the second flange 5；
Step 4, installs in conduit 4 and becomes oar cable and slip ring.
The conduit 4 being connected due to some joints runs through in the main shaft 6 of pipe the axle 3 and blower fan being arranged on gear-box, described pipe axle 3
Outer end connects the first flange 1, and main shaft 6 outer end connects the second flange 5, described first flange the 1, second flange 5 all with conduit 4 screw thread
Connect, thus pipe axle 3 is linked together with main shaft 6 by conduit 4, it is achieved synchronous rotary, such treating method solves
Gear-box pipe axle 3 and main shaft 6 and planet carrier can not synchronous rotary thus ultimately result in gear-box pitch control cable with pipe axle 3 not
Synchronous rotary, twist off cable, and when using this maintenance unit reduce the original maintenance cost of equipment and shorten original maintenance
Between.
