Description
Technical Field
The utility model relates to a wind wheel kuppe centering device.
Background
The coaxiality of the blade hole center of the wind wheel air guide sleeve of the wind turbine generator set and the center of the hub variable pitch bearing cannot be measured, the installation quality cannot be guaranteed only by visual inspection and tape measure, labor and time are wasted, and a great mass accident that the outer circle of the root of the blade collides with the inner circle of the blade hole of the air guide sleeve occurs too much when the blade is installed in a wind field.
Disclosure of Invention
In order to overcome the not enough of prior art, the utility model provides a wind wheel kuppe centering device effectively guarantees wheel hub and becomes the axiality in oar bearing and kuppe paddle hole, improves installation work efficiency and precision, eliminates wind field paddle installation quality potential safety hazard.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a novel wind wheel kuppe centering device, includes horizontal pole, connecting block assembly, fixed inserted bar and adjusting screw, the horizontal pole both ends are connected with the connecting block assembly, and fixed inserted bar is connected with connecting block assembly and change oar bearing centre bore respectively, adjusting screw is connected with the silk hole on the connecting block assembly.
Furthermore, a mounting hole is formed in the connecting hole assembly, the upper end of the fixed inserting rod penetrates through the mounting hole, and a gasket and a nut are sleeved on the thread section of the upper end of the fixed inserting rod.
Still further, the outer end of adjusting screw is equipped with the position sleeve.
The beneficial effects of the utility model are that: the coaxiality of the hub variable pitch bearing and the blade hole of the air guide sleeve is effectively ensured, the installation work efficiency and precision are improved, and the potential safety hazard of the installation quality of the blades in the wind field is eliminated.

Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Referring to fig. 1-3, a novel wind wheel air guide sleeve centering device comprises a cross rod, a connecting block assembly, a fixed inserted rod and an adjusting screw rod, wherein two ends of the cross rod are connected with the connecting block assembly, the fixed inserted rod is respectively connected with the connecting block assembly and a center hole of a variable pitch bearing, and the adjusting screw rod is connected with a screw hole in the connecting block assembly and can be used for adjusting the size precision in a left-right mode.
Furthermore, a mounting hole is formed in the connecting hole assembly, the upper end of the fixed inserting rod penetrates through the mounting hole, and a gasket and a nut are sleeved on the thread section of the upper end of the fixed inserting rod.
Still further, the outer end of adjusting screw is equipped with the position sleeve.
The way of fixing the hub: the guide cover is hoisted and sleeved outside the hub, and the guide cover is fastened by bolts after the centering size meets the standard through the upper and lower connecting supports.
And taking the inner circle of the variable pitch bearing as an installation reference, respectively installing a wind wheel and air guide sleeve centering device on the 3-surface variable pitch bearing, and respectively supporting 2 adjusting screws on the wind wheel and air guide sleeve centering device on the inner circle of the air guide sleeve blade hole.
The distance between the center point of the air guide sleeve mounting frame and the four points of the air guide sleeve blade hole in the diameter direction is measured by a circle ruler, and the error is not more than 10mm by adjusting 2 adjusting screws on the air guide sleeve centering device of the wind wheel.
And after all the bolts for connecting the air guide sleeve and the hub are screwed down to a rated torque, the air guide sleeve mounting frame is dismounted, and the mounting is finished.
The working process of the embodiment is as follows:
1. fixing the hub, hoisting the air guide sleeve and sleeving the air guide sleeve outside the hub, connecting the air guide sleeve and the hub by bolts through an upper connecting support and a lower connecting support, and fastening the bolts after the centering size meets the standard.
2. And taking the inner circle of the variable pitch bearing as an installation reference, respectively installing a wind wheel and air guide sleeve centering device on the 3-surface variable pitch bearing, and respectively supporting 2 adjusting screws on the wind wheel and air guide sleeve centering device on the inner circle of the air guide sleeve blade hole.
3. The distance between the center point of the air guide sleeve mounting frame and the four points of the air guide sleeve blade hole in the diameter direction is measured by a circle ruler, and the error is not more than 10mm by adjusting 2 adjusting screws on the air guide sleeve centering device of the wind wheel.
4. And after all the bolts for connecting the air guide sleeve and the hub are screwed down to a rated torque, the air guide sleeve mounting frame is dismounted, and the mounting is finished.
According to the scheme of the embodiment, 1 set of equipment only needs 1 person to spend 5 minutes, and a travelling crane does not need to be occupied; the assembly space occupies little; time and labor are saved; after the embodiment is adopted, only 5 minutes are needed for installing 1 air guide sleeve centering bracket by 1 person, and the assembly space is very small; time and labor are saved. 4.5 working hours are saved compared with the original work. If 2000 machines are produced annually, 60 yuan per hour, 4.5 × 60 × 2000 × 54 ten thousand yuan can be saved for the company annually. The installation can be completed only by the following implementation. The working safety of operators is better ensured.
