Positioning mechanism used for cable cutting

Abstract

The invention relates to a positioning mechanism used for cable cutting. The positioning mechanism comprises a supporting mechanism; the supporting mechanism includes a top plate and a bottom plate which are symmetrically arranged in the vertical direction; four vertical bars arranged symmetrically in pairs are fixedly connected between the top plate and the bottom plate; a sliding slot is formedin each vertical bar; two floating rollers are arranged between the top plate and the bottom plate; and the two floating rollers separately slide on two symmetrical vertical bars. Since the detectingend of a distance measuring wheel touches a fixed roller, the detecting end of the distance measuring wheel can rotate, and calculates the reeling and unreeling length of a cable, and thus, an operator can visually observe the reeling and unreeling length of the cable; during cutting, the fixed rollers and the floating rollers are locked through locking mechanisms to increase the friction of the cable, and thereby, the cable is fixed; and then, cable shear pliers are utilized to cut off the cable from a position between the two floating rollers, so that positioning of the reeling and unreelinglength of the cable is realized, and meanwhile, the cable is limited to guarantee stability during cable cutting.

Description

technical field [0001] The invention relates to the technical field of electric power auxiliary equipment, in particular to a positioning mechanism for cable cutting. Background technique [0002] The wire and cable industry is the second largest industry in China after the automobile industry, and the product variety satisfaction rate and domestic market share both exceed 90%. In the world, the total output value of China's wire and cable has surpassed that of the United States, becoming the world's largest producer of wire and cable. It is usually a rope-like cable twisted by several or groups of wires (at least two in each group), each group of wires is insulated from each other, and is often twisted around a center, and the entire outer surface is covered with a high degree of insulation the covering layer. Most of them are erected in the air or installed underground or underwater for telecommunications or power transmission. Cables can be divided into power cables, co...
