The present application relates to a kind of accompanying turnover assembly and conveying mechanism with the assembly, it relates to conveying equipment technical field, accompanying turnover assembly includes turnover guide base and turnover piece, base is provided with the cross broken line type guide groove of positive slope section, reverse slope section, turnover piece is provided with the guide pin of central symmetry arrangement, guide pin and guide groove are gapless sliding fit, rely on the spatial trajectory constraint of guide groove, turnover piece is limited driving synchronous rotation in linear conveying process by groove wall, conveying mechanism connects into annular chain body by connecting mechanism to multiple turnover pieces, and supporting plate linkage opening and closing of two groups of material is realized by matched connecting rod gear meshing structure.The present application discards independent rotating driving element, and pure mechanical groove direction is realized accompanying synchronous turnover, structure is simple and compact, action linkage precision is high, can change turnover parameter by adjusting guide groove line type, is applicable to automatic turnover moulding condition in the conveying process of various workpieces.

The invention provides a large vehicle-mounted antenna lifting platform, and belongs to the technical field of antenna lifting platforms. Comprising a carrying table and a tower body, the tower body is arranged above the carrying table, the tower body is formed by sleeving a main tower, an auxiliary tower and a plurality of sub-towers from outside to inside, a lodging device is arranged at the top of the carrying table, and the telescopic end of the lodging device is hinged to the main tower to drive the tower body to rotate to be in a vertical or horizontal state above the carrying table; the lifting mechanism is used for driving the tower body to stretch out and draw back, and the lifting mechanism is connected with the main tower; and the outer side of the main tower is fixedly connected with a winding device. The sliding mechanism composed of the rail and the sliding block is arranged among the main tower, the auxiliary tower and the sub-tower to replace a guide piece of a traditional U-shaped pulley, when the tower body stretches out and draws back, the rail slides on the inner side of the sliding block, lateral constraint can be provided for stretching out and drawing back of the tower body, the movement gap can be reduced, and the movement efficiency is improved. And transverse shaking of the tower body under the action of a load or wind power can be inhibited, so that the stability of the antenna working platform is ensured.
