Description

Automatic device for stripping multi-core control cable and stripping method thereof

Technical Field

The invention belongs to the technical field of mechanized construction in the power construction industry, and particularly relates to an automatic device for stripping a multi-core control cable and a stripping method thereof.

Background

At present, the secondary equipment of a built transformer station mostly adopts a multi-core control cable to be responsible for signal acquisition and transmission. The control cable structure is different from the current-carrying cable, and the control cable is formed by wrapping a plurality of control wires in the control cable by using a plurality of layers of skins made of different materials, wherein the skins can be divided into an insulating layer, an aluminum armor layer, an insulating layer and a shielding layer.

The traditional cable stripper has higher stripping efficiency on a current-carrying single-core cable, and the traditional stripper operation mode needs an operator to hold a device and realizes the stripping of the cable skin by means of continuous feeding and rotary cutting of a cutter. However, for a multi-core control cable with a complex structure, the conventional peeler has the following defects:

(1) The work environment and objects have limitations. The traditional stripper is mostly suitable for carrying cables on the overhead transmission line of the distribution network, and cannot be suitable for control cables of a transformer substation.

(2) The peeling mode is single. The cable type and specification of different structures have no strong adaptability, and the outer layers of various different materials cannot be peeled off in a single peeling operation mode.

(3) Too large to accommodate in-situ environments. The environment of a transformer substation under construction is complex, the available space in front of a secondary equipment cabinet is narrow, the road surface jolts, and part of large-scale devices cannot perform operation.

(4) The peeling process cannot meet the requirements. The traditional peeling mode has the defect of damaging the inner core, and the efficiency is greatly reduced along with the increase of the peeling length, so that the peeling effect cannot meet the construction process requirements of the transformer substation.

Simultaneously, the purpose that the stripped covering layer is separated in time is achieved by synchronously rotating the wire feeding wheels in the two parts or rotating the wire feeding wheels in the single part.

As shown in fig. 9, the electronic control unit 4 includes a control box, a circuit board, and a battery.

The control box is a base, is fixed on the box body of the driving clamping rotating member 1, and is connected with the fixed seat of the driven clamping rotating member 3, so that four parts in the peeling device are connected in series to form a whole.

6. Along with the aluminium armour is torn the separation, the induction wheel is rotated to aluminium armour with the knife rest dish and is broken away from the position after, does not have the metalwork between induction wheel and the sled shovel head, and the return circuit of both components is broken off, and sled shovel head stops feeding, but knife rest dish continues to rotate, until aluminium armour layer is completely by sled shovel head shovel tearing, accomplishes the operation of peeling off of second aluminium armour layer, then same control initiative and follow-up clamp wire feeding wheel in the rotating member independently rotate, discharges the cable with second aluminium armour layer.

7. And then stripping the third insulating layer by adopting the method which is the same as the stripping mode of the first insulating layer.

8.
