Automatic pretreatment device of three-core cross-linked cable connector

Abstract

The invention discloses an automatic pretreatment device of a three-core cross-linked cable connector. The automatic pretreatment device comprises an automatic rack, a rotary cutter mechanism, a rotary blade mechanism, a precision saw blade cutting mechanism, a cutter longitudinal movement guide rail, a cutter longitudinal driving synchronization belt, a cutter longitudinal moving base and a cutter longitudinal driving stepping motor. The rotary cutter mechanism is arranged at the upper end of the cutter longitudinal moving base; and the precision saw blade cutting mechanism is arranged at one side of the rotary cutter mechanism by the rotary blade mechanism. When the rotary cutter mechanism rotates, the rotary blade mechanism and the precision saw blade cutting mechanism are driven to make annular motions. Therefore, cable pretreatment process problems of largest labor amount and highest fineness requirement in cable connector construction are solved; and thus the labor intensity of the construction worker is reduced, the construction quality of the cable connector is controlled, the safety operation of the power cable is guaranteed, and the great economic benefits are created.

Description

technical field [0001] The invention relates to the field of power cable installation and construction, in particular to an automatic pretreatment equipment for three-core cross-linked cable joints, which can automatically complete the cable pretreatment process for making cable terminal joints and intermediate joints. Background technique [0002] With the continuous and rapid development of urbanization, overhead power supply lines are gradually replaced by power cables. The power cable body and cable accessories (cable terminal joint accessories and intermediate joint accessories) can be made by professional manufacturers according to national standards, but the cable accessories Installation must be done at the construction site. Cable accessories are mainly used for the connection of various electrical equipment such as switches, transformers, and cables. Key technologies: conductor connection technology, electric field control technology, insulation technology, sealin...

AI Technical Summary

Problems solved by technology

Due to the complicated manufacturing process, it is not easy for construction workers to master it skillfully, construction defects often appear, and most of the power failures are caused by such reasons

In order to reduce construction defects, the industry gradually uses some simple manual tools with reference to foreign methods, such as cable cutters, small electric band saws, manual strippers, electro-hydraulic pliers, etc., which only slightly reduce the amount of labor. For cable pretreatment Key quality factors, such as the cutting depth and position accuracy control of the cable sheath, the stripping depth and position accuracy of the shielding layer, semiconducting layer, and insulating layer of the phase-splitting cable, the shape of the cutting section and the surface quality, etc., have almost no improvement, on the contrary Because these tools are generally heavy, the operation and adjustment still rely on the experience and feel of the construction personnel, and the flexibility is very poor. Construction personnel are often reluctant to use them and continue to use the most primitive tools for operation.

Since there is no better way to ensure the quality of cable joint construction, the only way in the industry at present is to conduct repeated technical level training and assessment for construction personnel, and the tools used in the training and assessment are all the most advanced ones mentioned above. Original tools, low efficiency, and the quality of workmanship cannot be effectively guaranteed
