The purpose of the utility model is realized like this: a special mounting bracket for a wind power tower cylinder bus comprises an upper connecting plate, a lower connecting plate, an upper mounting seat and a lower mounting seat, wherein the upper connecting plate and the lower connecting plate are arranged transversely and used for connecting a power transmission bus; the lower connecting plate is longitudinally provided with a waist-shaped hole, and the lower connecting screw penetrates through the waist-shaped hole to be connected with the lower mounting seat after being sleeved with the first base plate, the spring and the second base plate.
The utility model can install the transmission buses in the tower, the upper and lower transmission buses can be connected by flexible connection, the upper mounting seat and the upper connecting plate are rigidly connected by the upper connecting screw, and the whole weight of the transmission buses is mainly born by the upper connecting screw; the lower connecting screw provides a flexible connection; the self expansion caused by heat and contraction caused by cold of the power transmission bus can be compensated by the up-and-down position movement of the lower connecting screw and the waist-shaped hole, and the left-and-right shaking of the tower can also be compensated by slight rotational deformation between the waist-shaped hole and the lower connecting screw; the left-right shaking of the tower barrel can be compensated through the expansion and contraction of the spring. Compared with the prior art, the utility model discloses can provide the three-dimensional compensation, through pretension adjustment spring force, it is convenient to make, can adapt to the installation of the transmission of electricity generating line of different weight, specification, uses more reliably. The installation of the transmission bus of the wind power tower is specially used.
The improved structure is characterized in that the upper connecting plate and the lower connecting plate are U-shaped bent plates. The U-shaped bending plate is high in strength, convenient to install and easy to manufacture, and waist-shaped holes can be formed through punching.
The further improvement is that the upper and lower power transmission buses are connected in a flexible connection in the tower barrel. And the flexible connection is adopted, so that the tower can adapt to the deformation of the tower from top to bottom in a large range.
The improved structure is characterized in that the upper mounting seat and the lower mounting seat are respectively provided with two mounting seats, the upper mounting seat and the lower mounting seat are distributed in a rectangular shape, and the lower mounting seat is provided with two corresponding waist-shaped holes. The mounting bases are distributed in a rectangular mode, the upper two mounting bases provide fixed locating points, and when the tower barrel shakes left and right, the lower two waist-shaped holes can move left and right within a proper range.
Further, the width of the waist-shaped hole is 1.05-1.25 times of the diameter of the lower connecting screw. The structure of the tower drum is that when the tower drum is rocked left and right, the lower connecting plate has enough movement space to adapt to left and right rocking of the tower drum.
