Equipment and process for weaving composite material

Abstract

The invention provides equipment and a process for weaving a composite materials; the equipment comprises a knitting machine and a mechanical arm, the knitting machine comprises a large circle, yarn spindles, two circular rings and a core mould; the yarn spindles are arranged on the inner side wall of the large circle, and are uniformly arranged along the circumferential direction of the inner side wall of the large circle; the two circular rings are arranged side by side, the two circular rings coincide with the central axis of the large circle, and a preset distance is reserved between the two circular rings, so that woven yarns can pass through the preset distance; the core mould is arranged in the circular rings in a penetrating mode, one end of the core mould is connected with the mechanical arm, and the mechanical arm is used for driving the core mould to do reciprocating motion along the central axis direction of the large circle; the type of the yarn spindles is at least two, the yarn spindles of all types rotate synchronously with the large circle, and the large circle revolves according to a preset trajectory. An insulation operating rod produced by the weaving process and the equipment is higher in fiber density compared with other insulating rod formed by other processes, internal air bubbles are fewer, the insulation operating rod has the advantages of being lighter in weight, better in mechanical and insulating performance and capable of being applied to overhauling work of extra-high voltage electric power engineering.

Description

technical field [0001] The invention relates to the technical field of braiding and pultrusion forming of insulating operating rods for high-voltage electric power, in particular, to a device and process for braiding composite materials. Background technique [0002] At present, with the development of electric power engineering, the UHV power grid (AC 1000kV, DC ±800kV, ±1100kV) has become the backbone grid of the State Grid. Insulated operating rods are often required for maintenance work items. Due to the high voltage level and large insulation interval of the UHV system, the size and weight of the insulating operating rod doubled. In order to reduce the workload of the operators, it is necessary to develop a light-duty UHV maintenance on the basis of satisfying the electrical and mechanical strength of the operating rod. Use an insulated operating rod. [0003] At present, insulated operating rods are used for UHV maintenance in China, and the molding process of insula...
