The above purpose is realized by the following technical scheme:
a wind generating set gear box replacing oil-cooled radiating fin supporting tool comprises a lifting platform, a driving device for driving the lifting platform to vertically ascend and descend, a base with a circular arc-shaped bottom surface and a positioning support;
the driving device is fixed on the base and connected with the lifting platform, four guide devices are connected between the lifting platform and the base, and the positioning support is fixed on the bottom surface of the base.
The wind generating set replaces a gear box oil cooling fin supporting tool, and the driving device comprises two lifter screws and two lifter supports;
the lifter support is fixed on the top of the base through a fixing bolt, the lifter screw is connected with the lifter support through a bearing, the thread directions of two ends of the lifter screw are opposite, the lifter screw is in threaded connection with a thread sleeve, each thread sleeve is hinged to one end of a lifter connecting rod, and the other end of the lifter connecting rod is hinged to the bottom of the lifting platform.
The wind generating set replace the oil cooling fin supporting tool of the gear box, and the guiding device is a telescopic sleeve rod.
The wind generating set replace the oil cooling fin support tool of the gear box, and a positioning baffle is fixed at the top of the lifting platform.
The wind generating set replace the oil cooling fin support tool of the gear box, and the lifting platform is arranged in an inclined mode.
Has the advantages that:
1. the utility model discloses when changing wind turbine generator system gear box oil cooling fin, use manpower sparingly, easy operation, work efficiency is high.
2. The utility model discloses when changing gear box oil cooling fin, mention the gear box top with the rope for the fin after, put the carriage between fin and gear box shock attenuation cover, insert the gear box shock attenuation cover manhole with the locating support, make the base position effectively fixed, difficult emergence lateral shifting, adjust the lift platform height through rotatory two riser handles, be equipped with guider, lateral shifting can not take place when the platform goes up and down, be favorable to fin fixing bolt's installation, and when demolising the fin, still can steadily descend the fin, whole working process saves the manpower and supports, use manpower sparingly, eliminate the rope and carry the difficult problem of drawing difficult installation fixing bolt, and elevating gear, lift platform, the base all can dismantle the connection, and convenient carrying.
Description of the drawings:
FIG. 1 is a front view of the present invention;
fig. 2 is a side view of the present invention;
FIG. 3 is a schematic structural view of a positioning bracket;
in the figure: 1. positioning a baffle plate; 2. a lifting platform; 3. a riser link; 4. a lifter handle; 5. a lifter screw; 6. a riser mount; 7. a base; 8. fixing the bolt; 9. positioning the bracket; 10. a guide device; 11. and (4) a threaded sleeve.
The specific implementation mode is as follows:
example 1:
a wind generating set changes gear box oil cooling fin and supports frock, the said wind generating set changes gear box oil cooling fin and supports frock and includes the lifting platform 2, drive the said lifting platform to rise vertically and the drive unit that descends, bottom surface take the form of arcuate base 7 and locating support 9;
the driving device is fixed on the base and connected with the lifting platform, four guide devices 10 are connected between the lifting platform and the base, and the positioning support is fixed on the bottom surface of the base.
Example 2:
according to the supporting tool for replacing the oil cooling fins of the gear box of the wind generating set in the embodiment 1, the driving device comprises two lifter screws 5 and two lifter brackets 6;
the lifter support pass through fixing bolt 8 to be fixed the base top, the lifter screw rod with the lifter support pass through the bearing and connect, the both ends screw thread opposite direction of lifter screw rod and on it with screw thread sleeve 11 threaded connection, each the screw thread sleeve on all with even the one end of lifter connecting rod 3 articulated, the other end of lifter connecting rod with lift platform's bottom articulated.
Example 3:
according to embodiment 1 or 2, the wind generating set replaces the oil cooling fin supporting tool of the gear box, and the guide device is a telescopic sleeve rod.
Example 4:
according to embodiment 1 or 2 or 3, the wind generating set oil cooling fin replacing support tool is characterized in that a positioning baffle is fixed to the top of the lifting platform.
Example 5:
according to the wind generating set replacement gearbox oil cooling fin support tool in the embodiment 1, 2, 3 or 4, the lifting platform is arranged in an inclined mode.
The working principle is as follows: the lifter frame passes through bolted connection with the base, the lifter connecting rod passes through round pin hub connection with lift platform, all be the swing joint, all can dismantle, when changing gear box oil cooling fin, mention the gear box top with the rope after with the fin, put between gear box shock attenuation cover and the fin after accomplishing the whole equipment of support frame, locating support inserts the gear box shock attenuation cover manhole at this moment, it is effectively fixed to make the base position, the difficult lateral shifting that takes place, the cambered surface and the gear shock attenuation cover appearance of base are identical, it is more firm to make the base like this, and is steady. After the support frame is fixed, the two lifter handles 4 are rotated, the angle of the lifter connecting rod can be changed, so that the function of adjusting the height of the lifting platform is realized, the lifting platform is in full contact with the surface of the radiating fin, the lifting platform is provided with a positioning baffle plate which is used for preventing the radiating fin from sliding on the lifting platform, the radiating fin is fixed and is not horizontal, and one side of the radiating fin is higher than the other side of the radiating fin, so that the lifting platform has inclination, at the moment, a rope for lifting the radiating fin is detached, the height of the lifting platform is adjusted by rotating the two lifter handles, the radiating fin is high, the bolt holes at the low end of the radiating fin correspond to the bolt holes of the radiating fin fixing frame, the device is provided with a guide device, the platform cannot shake when lifting, or the front side, the back side and the right side can move transversely, and the installation of the radiating fin fixing bolt is facilitated.
If the support frame is used for removing the oil cooling radiating fins, the height of the lifting platform is adjusted firstly to fully prop against the surfaces of the oil cooling radiating fins, then the oil cooling radiating fin fixing bolts are removed, then the height of the lifting platform is slowly adjusted to be lowered to the lowest point, then the lifting platform is fixed to the ground through the ropes, if the radiating fins are directly fixed through the ropes, after the fixing bolts are removed, the radiating fins are not horizontal and easy to shake, the danger of damaging personnel and other parts is caused, the whole process operation can be completed only by 2-3 persons, a large amount of manpower is saved, the operation is simple, and the working efficiency is high.
