Description
Technical field：
The utility model is related to a kind of simple wind turbine brake gears.
Background technology：
Two model ASS-2700/1700-2D's of every unit outfit of the current overcritical thermal power plant units of 2 × 350MW
Air-introduced machine, the method for operation two transport 0 standby, rotation speed of fan 990r/min, and total head is upgraded to 11072pa, and TB operating mode flows are 302.82m3/
S, opposite direction are arranged in juxtaposition, and a set of four flabellums louver type damper door is arranged in outlet, are confluence threeway behind the door, be equipped in threeway every
Plate.
When normal startup operation, first side wind turbine is started, it is rear to start other side wind turbine, after a Fans start, by
Arrange that wind pressure flow is larger in wind turbine opposite direction, whole air quantity can not be drained or hindered by partition board and offside fan outlet baffle door
Gear, the wind turbine started after causing the wind with pressure to scurry into, causes to reverse, and such as starts wind turbine at this time, certainly will increase to wind turbine
Damage, exist simultaneously larger hidden danger.
Invention content：
The purpose of this utility model is to provide a kind of simple wind turbine brake gear.
Above-mentioned purpose is realized by following technical scheme：
A kind of simple wind turbine brake gear, composition include：The side of brake plug and fan shaft, the brake plug is vertical
Face is connect with thrust plate, and one end plate face of the thrust plate is connect with screw thread distance rod, the end of the screw thread distance rod
It is fixedly connected with threaded rod force outer-hexagonal head, the threaded rod is inserted in inner screw sheath, the both sides of the brake plug
Parallel is provided with two pieces of side shields adjustable in pitch, and the side shield described in two pieces is connect with the side of the brake plug, institute
The two pieces of thread bush that are provided with that the side for the inner screw sheath stated is parallel support, the inclined-plane and the fan shaft of the brake plug
Axial plane contact.
The simple wind turbine brake gear, side shield, thread bush support, the internal thread described in two pieces
Set and the brake plug are vertically mounted on the top of platen.
The simple wind turbine brake gear, the brake plug are the triangular structure of right angle or rubber skin of stopper material
Fill in the triangular structure of right angle of material.
The beneficial effects of the utility model：
1. the utility model, which avoids Fan Equipment under old terms, does not have brake apparatus, rear start can only band after wind turbine reverses
The components such as axis, shaft coupling are played the role of protection by the phenomenon that turned upside down starts, convenient and practical, of low cost.
The utility model carried out operation before wind turbine is reversed or reversed, to the device and braked, in wind turbine
The device can release braking state when startup, realize and protected to wind turbine.
The utility model is provided with three directions of thrust plate and side shield and fills in capable force to brake, effectively controls its brake
Car state, while the tangential friction force generated to contact wedge shape brake plug using reversing shaft, are driven while retarding braking and are stopped
Vehicle plug stoppers inwards, forms more more dynamic tighter on-position, and frictional force is enough when to ensure just contact, prevents from skidding, with one
Determine thrust to stopper brake plug on axis and table top；When the axis rotates forward, tangential friction force drives brake plug to extract outward, until
Brake plug is thoroughly detached from bearing, realizes and releases brake function.
Utility model device is filled in before use, brake should be installed first, is adjusted side shield and push plate, is made brake plug side
Face, bottom surface, thrust face four direction are fixed, and in wind turbine inversion process, are revolved to the external turret head force of compaction direction with spanner
Turn threaded rod, threaded rod connection thrust plate is moved, and brake plug is filled between platen and axis, instead under the thrust of thrust plate
The frictional force retarding braking that the wedge shape brake plug that shaft contacts are filled in generates, while tangential friction force can also drive brake plug inwards
It stoppers, forms more more dynamic tighter on-position, stop until reversing, can also realize the system to axis by above step before reversing
It is dynamic；Wind turbine withdraws thrust plate force before starting, and slowly removes after thrust plate leaves brake plug a distance and starts wind turbine, wind turbine
Start rear axle to rotate forward, tangential friction force directly drives brake plug to extract outward, and brake releases, and such as brake the tension filled in, and opens
Thrust plate should be positioned before dynamic, adjust side shield, axial force distribution loosens brake plug, and such as brake is filled in more loose, can started
The tightness for starting synchronous adjustment thrust plate with wind turbine in the process, makes wind turbine smoothly start.
