Cable self-centering holding device

Abstract

A cable self-centering holding device comprises a clamping portion which is used for clamping a target cable, wherein the clamping portion comprises a plurality of first clamping parts arranged on theperiphery of the target cable; first connecting parts, wherein the number of the first connecting parts is matched with that of the first clamping parts, and the first connecting parts are rotationally connected with the first clamping parts respectively; first rotating parts, wherein the number of the first rotating parts is matched with that of the first clamping parts, and the first rotating parts are connected with the ends, away from the first clamping parts, of the first connecting parts; a second connecting part which is in transmission connection with the first rotating parts, so thatthe first rotating parts rotate synchronously; and a driving part which is in transmission connection with at least one first rotating part and can drive at least one first rotating part to rotate. When the device is in use, the target cable is located at the position of a center shaft among the multiple first clamping parts during clamping each time, the center of the cable is located at the same position when the subsequent target cable enters a stripping and / or polishing mechanism, and the cable stripping and polishing precision is improved.

Description

technical field [0001] The invention relates to a tightening device, in particular to a cable self-centering tightening device. Background technique [0002] High-voltage cables are an important part of urban power distribution systems, which can effectively save line corridors and reduce the impact of environmental factors. The proportion of high-voltage cables in many urban distribution networks is increasing. Since the manufacturing length of a single cable is generally less than limited, the installation of cables In the process of laying and overhauling, intermediate joints are indispensable, and the demand is huge. At present, cable joints mainly rely on manual on-site production, and the construction quality has become a major hidden danger in the operation of cable lines. In the process of cable joint production, it is easy to be affected by the surrounding environment, construction personnel's technology, construction period, etc., leaving various small defects on ...

AI Technical Summary

Problems solved by technology

[0003] At present, in the production of high-voltage cable intermediate joints and terminal heads, it is necessary to strip and / or polish the high-voltage cable insulation shielding layer at the cable intermediate joints and terminal heads. The existing cable intermediate joints and terminal heads are stripped and / or polished. The method is to manually insert the cable to be polished into the exploitation and / or grinding mechanism for grinding, but when the cable to be polished is manually inserted into the exploitation and / or grinding mechanism, due to human subjective judgment Different, when extending into the corresponding mechanism, the center of the cable is different when extending, resulting in insufficient grinding precision
