At present, for domestic power generation enterprises, in recent years, large-scale power generation group companies develop rapidly, and newly built units continuously build high-capacity high-parameter green coal power with higher speed to gradually replace old units. Under the conditions of high capacity and large output of the unit, most axial flow fans are adopted as large-scale fan equipment mainly used by coal-fired power plants. One of the most important models is the TLT movable blade adjustable axial flow fan manufactured by German original factory introduction or Shanghai blower factory introduction German technology.

A petiole nut needs to be rotated when the TLT movable vane adjustable axial flow fan petiole component is installed and removed. Due to the fact that no corresponding fixing part exists, all parts rotate with the blade shank in 360 degrees during the process of dismounting or mounting. In the existing installation or removal process, a maintainer often inserts an iron rod or an iron pipe to fix. This mode is comparatively rude, and if the iron bar is fixed not in place, also easy damage equipment and produce the potential safety hazard such as iron bar pop-up.

Preferably, the front side mounting include first arm lock and second arm lock, first arm lock, second arm lock fixed locate the front side bottom of bottom plate, first arm lock and second arm lock parallel relative setting.

Preferably, the horizontal height of the top surfaces of the first clamping arm and the second clamping arm is lower than that of the top surface of the bottom plate.

Preferably, the first positioning hole and the second positioning hole have the same aperture, and the central axes of the first positioning hole and the second positioning hole are overlapped.

Preferably, the fixing device further comprises a positioning pin, and the positioning pin is inserted into the first positioning hole and the second positioning hole.

Preferably, the side surfaces of the first vertical plate and the second vertical plate are parallel to the front side surface of the bottom plate.

Compared with the prior art, the utility model has the advantages of as follows:

the utility model discloses can carry out dual installation to TLT movable vane petiole and fix, utilize arm lock, riser to restrict the petiole rotation, can effectively mutually support with the balancing piece structure of petiole, simple to operate, the security performance is high, has avoidd the potential danger that original dismouting in-process maloperation causes, can promote the safety and stability of maintenance efficiency and maintenance greatly in the batch production maintenance.
