The invention relates to the technical field of inclined overlapping winding type composite material processing, in particular to an accompanying trolley for inclined overlapping winding. The accompanying trolley comprises a feeding mechanism and an accompanying trolley body, a deflection device is arranged between the feeding mechanism and the accompanying trolley body, a belt disc, a balance swinging rod, a tension module, a shearing module, a deflection correcting module and a hot pressing module are arranged on the accompanying trolley body, wherein a fiber band on the belt disc sequentially passes through the balance swinging rod, the tension module, the shearing module, the deflection correcting module and the hot pressing module; the deflection correcting module is used for realizing accurate control of deflection quantity of the fiber band, so that the accuracy is greatly improved when winding is conducted; the accompanying trolley body is provided with a deflection structure,the deflection of the accompanying trolley body is controlled through a motor, so that the accompanying trolley body can meet winding requirements of different sizes and angles; the operation inconvenience and the yarn threading difficulty are avoided, so that moving of the fiber band in the winding process is facilitated, and manual operation is not needed; the overall structure is compact, and action is reliable; and the shearing module is arranged, so that a notch with a certain length can be produced through cutting on the fiber band according to requirements, and the influence of tensioncaused by fan-shaped deformation during inclined overlapping winding of the fiber band is eliminated.
