Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to a wind wheel hub locking device.
[ background of the invention ]
A fan hub locking device is a safety protection device of a wind generating set. A wind wheel locking device of the wind driven generator is used for fixing the wind wheel in the process of overhauling the generator or other special conditions. When the wind generating set is maintained and overhauled, the wind wheel must be locked, and safety accidents caused by rotation of the wind wheel are prevented. The locking disk is fixedly arranged on a wind wheel of the wind driven generator and rotates along with the wind wheel, the cabin underframe is relatively static, pin holes are formed in the locking disk, and the locking pin is arranged on the underframe. When the fan starts to brake, the wind wheel gradually decelerates until the wind wheel is close to a stop state, maintenance personnel insert the locking pins into the corresponding pin holes to stop the rotation of the wind wheel, and the maintenance personnel can safely enter the hub to perform related maintenance work.
At present, the structure of a blade locking device of a wind generating set mainly adopts a pin shaft type structure, and a pin shaft is pushed into a blade fixing groove by manual operation. The manual locking designed by the original factory is controlled by a manual screw, the friction resistance is large in the working operation process, and the fan is likely to rust in the later period, so that the friction resistance is larger, the time and labor are wasted during the operation and maintenance of the fan, and as is known, a wind driven generator is very high and is positioned at a position with larger wind power, so that the original generator set servomotor locking device cannot meet the requirement of the fan, and the safety of the fan cannot be fully ensured.

[ description of the drawings ]
The invention will be further described with reference to the following examples with reference to the accompanying drawings.
Fig. 1 is a schematic view of a wind wheel hub locking device of the present invention.
[ detailed description ] embodiments
The embodiment of the utility model provides a through providing a wind wheel hub locking device, solved the hard technical problem of operation among the prior art, realized field operation function simple, rational in infrastructure, small, installation maintenance convenience, easy operation is laborsaving, and factor of safety is high. The technical effect of (1).
The utility model relates to an embodiment:
as shown in figure 1, the utility model relates to a wind wheel hub locking device, include
The cylinder body 1 is internally provided with a cavity 11;
a manual hydraulic pump 2; the manual hydraulic pump 2 is arranged on one side of the cylinder body 1; the manual hydraulic pump 2 is provided with a handle 21, and the piston rod 4 can be driven to move by shaking the handle 21 up and down;
the fixed flange 3 is arranged on the other side of the cylinder body 1;
the piston rod 4 is arranged in the cavity 11 of the cylinder body 1, and the piston rod 4 penetrates through the fixed flange 3;
the locking pin shaft 5 is connected with one end part of the piston rod 4, the locking pin shaft 5 further comprises a half-dividing clamping ring 8, and one end part of the piston rod 4 is connected to the locking pin shaft 5 through the half-dividing clamping ring 8;
a pressure gauge 6, wherein the pressure gauge 6 is connected to the cavity 11;
and the reversing valve 7 is arranged on the cylinder body 1 and connected to the cavity 11, the reversing valve 7 is a manual reversing valve, a locking mechanism is arranged on the manual reversing valve and used for locking after reversing of the manual reversing valve is completed, and the manual reversing valve cannot be touched by workers by mistake. The manual directional control valve is a rotationally operated directional control valve 7 which controls the insertion and withdrawal of the locking device piston rod 4. The control valve core is operated by a manual adjusting knob (the rotation angle is 2 multiplied by 90 degrees), the generated rotation is converted into axial movement through a screw device and directly acts on the control valve core, and the control valve core moves to a required tail end position and is opened to a required flow quantity position. The position of the knob can control the actual switching position of the valve core according to the eye force.
The wind wheel hub locking device has the function of converting mechanical energy of a power machine (such as a motor) into pressure energy of liquid. Thereby dropping the locking pin into the wind wheel hole.
After the wind wheel hub locking device is put into operation, the piston and the locking pin are in a self-holding state, the locking pin can only be withdrawn by manually operating the direction control valve to a withdrawing position and continuously operating the manual hydraulic pump 2, and meanwhile, the pressure gauge 6 is arranged, so that the pressure of the operation of the device can be checked more visually.
When the oil pressure regulating device is used, the direction is set through the reversing valve 7, then the manual hydraulic pump 2 is used for braking, so that the oil in the cavity 11 is subjected to pressure, the piston rod 4 is moved according to the pressure, and the piston rod 4 can drive the locking pin shaft 5 to move.
