Spinning blade mechanism of automatic preprocessing equipment for three-core crosslinked cable joint

Abstract

The invention discloses a spinning blade mechanism of automatic preprocessing equipment for a three-core crosslinked cable joint, and the mechanism comprises a pedestal, a spinning blade positioning pin, a battery, a controller, a stepping motor, and a rotary-cut depth reference plate. The interior of the pedestal is also provided with a screw rod, a rectangular sliding block, a blade fixing screw, and a spinning blade. The screw rod is connected with the stepping motor, and is cooperatively connected with a thread at the central part of the rectangular sliding block. The blade fixing screw enables the spinning blade to be fixed in a blade groove below the rectangular sliding block. The stepping motor rotates to drive the screw rod to rotate, thereby driving the rectangular sliding block to rotate, and achieve the adjustment of the depth of the spinning blade. Through the above mode, the mechanism can rotate along a preset cutting track, completes the annular cutting, peeling, chamfering and flattening at a time, greatly reduces the labor intensity of a construction worker, effectively manages and controls the construction quality of a cable joint, guarantees the safety operation of a power cable, and is considerable in economic benefits.

Description

technical field [0001] The invention relates to the field of power cable installation and construction, in particular to a rotary blade mechanism for automatic pretreatment equipment for three-core cross-linked cable 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, sealing technology, coupled with the heavy weight of the cable body, the installation work can be rega...

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
