Problems solved by technology

In the prior art, in order to realize the function of adjusting the angle of the overall structure of the antenna, it is necessary to set up arc bolt holes on the flange plate at the bottom of the antenna pole. When the adjustment angle is large, the length of the arc bolt holes will also increase. In addition, , a large area of ​​cable holes is opened on the flange, and due to the need for rotation, the ends of the arc bolt holes cannot be provided with bolts, which will cause uneven bolt layout on the flange, which is very unfavorable in strength calculation , making bolted connections less reliable

Abstract

The embodiment of the invention discloses a rotation device. The rotation device comprises a first flange disc, a second flange disc, a first connection piece and a second connection piece, wherein afirst through hole and a first rail groove are formed in the first flange disc, a second through hole and a second rail groove are formed in the second flange disc, the first connection piece penetrates through the first through hole and the second rail groove, the second connection piece penetrates through the first rail groove and the second through hole, when the first flange disc or the secondflange disc rotates, the first connection piece moves in the second rail groove, and the second connection piece moves in the first rail groove. The stress of the first flange disc and the second flange disc can be more uniform as well as integral rotation is achieved, so that the connection reliability is improved.

Description

technical field [0001] The present application relates to the transmission field, in particular to a rotating device. Background technique [0002] In the iron tower base station, in order to achieve the beautification effect of the iron tower, the pole is connected to the tower on the top of the tower through the flange, and then the antenna or radio remote unit (radio remote unit, RRU) equipment and other equipment are installed on the pole, which can reduce the The installation volume of the antenna and other equipment can be coordinated and unified with the tower body after adding a camouflage cover to achieve a beautifying effect. However, since the directional antenna needs to adjust the direction angle, the existing technology realizes the angle adjustment of a single antenna by adjusting the connection between the antenna and the pole, and the flange connecting the antenna section and the iron tower is a fixing bolt hole, which cannot be rotated as a whole. Therefor...
