The utility model discloses a kind of replacement frock for yaw friction plate of wind driven generator, including fixed plate, more than one mounting hole is offered in the fixed plate, the mounting hole is corresponding with the adjustment bolt hole on wind-driven generator side bearings, for fixing fixed plate by adjusting bolt, one end downward bending of the fixed plate forms spacing stressed plate, and clamping screw of the spacing stressed plate on wind-driven generator side bearings set, for making the reaction arm of force of hydraulic spanner be resisted against when dismantling clamping screw on spacing stressed plate.The utility model has the advantages that simple and compact for structure, flexible to operation, low manufacture cost, can effectively improve hydraulic spanner reaction arm of force security reliability.
Description
Technical field
The utility model is mainly concerned with field of wind power equipment, and in particular to one kind is rubbed for wind driven generator yaw
The replacement frock of pad.
Background technology
Need to dismantle horizontal hanger rod and main frame in 1.65MW fan yaw friction plate replacement process, wherein needing to remove position
In multiple connection bolts on wind-driven generator side bearings.The multiple connection bolt includes multiple adjustment bolts and multiple locks
Tight bolt.Clamping screw model M36 × 220, moment values 3400Nm, needs to be added with TU-3 hydraulic spanners in disassembly process
55 sleeves, but due to the shape and structure problem of horizontal hanger rod, cause hydraulic spanner during dismantling with clamping screw, instead
Without safe and reliable stress point, this to dismantle operation dangerous reliable and fragile clamping screw acting force arm.
Utility model content
The technical problem that the utility model is solved is：In view of the problems of the existing technology, there is provided a kind of structure letter
Single compact, flexible to operation, low manufacture cost, can effectively improve hydraulic spanner reaction arm of force security reliability be used for wind
Power generator yaws the replacement frock of friction plate.
In order to solve the above technical problems, the utility model uses following technical scheme：
A kind of replacement frock for yaw friction plate of wind driven generator, including fixed plate, offer in the fixed plate
More than one mounting hole, the mounting hole is corresponding with the adjustment bolt hole on wind-driven generator side bearings, for passing through
Adjustment bolt fixes fixed plate, and one end downward bending of the fixed plate forms spacing stressed plate, and the spacing stressed plate leans on
Clamping screw on nearly wind-driven generator side bearings sets, for making the reaction arm of force of hydraulic spanner in dismounting locking screw
It is resisted against during bolt on spacing stressed plate.
As further improvement of the utility model, the spacing stressed plate is equipped with one layer of elastic layer, makees in order to counter
With the arm of force against.
As further improvement of the utility model, the elastic layer is made of rubber.
As further improvement of the utility model, the mounting hole is three.
Compared with prior art, the utility model has the advantage of：
First, the replacement tool structure simple and compact of the utility model, easily fabricated, and take full advantage of wind-power electricity generation
Original adjustment bolt hole and adjustment bolt are fixed on pusher side spherical bearing, occupy little space, and have well adapted to wind-force hair
The reality of motor group narrow space so that installation operation is convenient, flexible.Second, the replacement frock of the utility model is using admittedly
Spacing stressed plate after fixed, the reaction arm of force that can be to the hydraulic spanner in operation are formed reliably against support so that anti-
Acting force arm has safe and reliable stress point, and then improves the safety-type and stability of operation, improves work efficiency.

Embodiment
The utility model is described in further detail below in conjunction with specific embodiments and the drawings.
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model provides a kind of replacement work for yaw friction plate of wind driven generator
Dress, including fixed plate 1, offers more than one mounting hole 11, the mounting hole 11 and wind-driven generator in the fixed plate 1
Adjustment bolt hole on side bearings is corresponding, for fixing fixed plate 1 by adjusting bolt, one end of the fixed plate 1
Downward bending forms spacing stressed plate 12, and clamping screw of the spacing stressed plate 12 on wind-driven generator side bearings is set
Put, for making the reaction arm of force of hydraulic spanner be resisted against when dismantling clamping screw on spacing stressed plate 12.Specific implementation
Principle is as follows：
Remove operation when, first the adjustment bolt A on wind-driven generator side bearings is pulled down, recycle adjustment bolt A and
Fixed plate 1 is fixed on wind-driven generator side bearings by mounting hole 11, and causes the spacing stress of 1 downward bending of fixed plate
Plate 12 is set towards clamping screw B, then carries out dismounting clamping screw B using work such as hydraulic spanners, and in disassembly process,
All the time so that the reaction arm of force C of hydraulic spanner is resisted against on spacing stressed plate 12（As shown in figure 3, reaction arm of force C has been supported
Lean against on spacing stressed plate 12, be ready for the adjustment bolt A of dismounting top）.The special scientific design more than, has as follows
Advantage：
First, the replacement tool structure simple and compact of the utility model, easily fabricated, and take full advantage of wind-power electricity generation
Original adjustment bolt hole and adjustment bolt are fixed on pusher side spherical bearing, occupy little space, and have well adapted to wind-force hair
The reality of motor group narrow space so that installation operation is convenient, flexible.Second, the replacement frock of the utility model is using admittedly
Spacing stressed plate 12 after fixed, reaction arm of force C that can be to the hydraulic spanner in operation are formed reliably against support so that
Reaction arm of force C has safe and reliable stress point, and then improves the safety-type and stability of operation, improves work effect
Rate.
Further, in the preferred embodiment, the spacing stressed plate 12 is equipped with one layer of elastic layer 13, in order to reaction
The arm of force against.Elastic layer 13 can to against the reaction arm of force formed elastic buffer so that spacing stressed plate 12（Fixed plate 1）
It will not be subject to the vibration effect of the reaction arm of force, improve the stability of the present apparatus.
Further, in the preferred embodiment, the elastic layer 13 is made of rubber.Certainly, in other embodiments, it is elastic
Layer 13 can also have other elastic materials such as silica gel or elastic cotton to be made, and should all belong to the scope of protection of the utility model.
Further, in the preferred embodiment, the mounting hole 11 is three.Three mounting holes 11 respectively pass through three tune
Whole bolt A is fixed on wind-driven generator side bearings, can play more firm support effect, stability is more preferably.
