Description

Automatic device for peeling multi-core control cable

Technical Field

The utility model belongs to the technical field of mechanized construction in the power construction industry, and particularly relates to an automatic device for peeling a multi-core control cable.

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.

1. initializing the device, opening an upper clamping block and a lower clamping block in a driving clamping rotating member and a driven clamping rotating member through a clamping motor, putting a cable in the clamping rotating member, and determining stripping length; when the cable is put into the middle position of the upper clamping block and the lower clamping block, the clamping motor rotates to drive the upper clamping block and the lower clamping block to be closed, the cable is clamped, the position is recorded, and the first insulating layer stripping operation is started.

2. After the cable is clamped, the rotating motor is started to drive the tool rest assembly to rotate along with the rotating gear, and meanwhile, the tool adjusting motor in the circular cutting tool rest rotates, so that the tool rest is slowly fed in the process of rotating around the cable until the cutter touches the second aluminum armor layer of the cable, the double tool tips touch the metal piece to form a loop, namely, the feeding is stopped, the position is maintained, the circular cutting of the first insulating layer is continuously completed through rotating around the cable.

3. After the annular cutting operation of the insulating layer is completed, the annular cutter heads are retracted, the rotating disc stops rotating, at the moment, two groups of radial cutter heads on the radial direction of the feeding cable cut into the insulating layer, metal pieces are sensed in the same sensing mode, then the feeding is stopped, then the wire feeding wheels in the driving and driven clamping rotating members contacted with the cable are controlled to rotate in the same direction, the insulating layer of the cable is cut to the section end of the cable from the radial direction of the cable, and then the wire feeding wheels in the driving and driven clamping rotating members are controlled to rotate reversely, so that the cable returns to the annular cutting position.

4. At this time, the insulating layer is completely cut around and cut off radially, the wire feeding wheels in the driving and driven clamping rotary members are respectively positioned at two sides of the annular tangential surface, the wire feeding wheel at one side which is not cut off radially is locked, the wire feeding wheel at one side which is completed radially is started, the insulating layer at one side which is completed circumferentially cut off and cut off radially is separated from the cable by friction force between the wire feeding wheel and the insulating layer of the cable, and the cutting off and discharging of the insulating layer are completed.

5. The operation of stripping of next layer aluminium armor is carried out, feed motor in the aluminium armor blade holder is started, make sled shovel head be close to the aluminium armor on the cable, start rotating electrical machines simultaneously, make the knife rest dish rotate along with rotatory tooth, when sled shovel head contact aluminium armor, aluminium armor can be pressed to the induction wheel at rear, continue to feed sled shovel head and progressively extrude aluminium armor, and along with rotating, sled shovel head can imbed in the gap of aluminium armor, then in lasting rotating, sled shovel head progressively prizes aluminium armor, because the centre gripping position of cable is close to aluminium armor sled origin, hide aluminium armor in it can not be pulled open.

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. Finally, the fourth nylon and copper foil shielding layer stripping operation is performed, at the moment, the motor in the front cutter holder in the flexible cutter holder is controlled to run, when the annular cutter head is fed to touch the nylon and copper foil shielding layer, the supporting force of the cutter head, which is applied by a cable, is counteracted by a pressure spring at the rear end of the flexible cutter holder to the majority, but at the same time, the cutter head part is kept not to be separated from the layer, and the cutter head can gradually scrape the nylon and copper foil shielding layer along with the gradual rotation of the cutter holder disc; when the layer is scraped, the cutter head is not contacted with the metal piece any more, and the loop is disconnected; at the moment, the annular cutter head is controlled to retract, and then the annular cutter head is matched with a wire feeding wheel in the driving and driven clamping rotating component to realize the complete coating stripping function.
