In some alternative embodiments, as shown in fig. 2, the front end of the body portion 422 of the cutter 42 is provided with a proximity switch 424. The proximity switch 424 is used to detect whether the aluminum strapping tape 100 is encountered, so that the aluminum strapping tape 100 is cut by being driven by the driving mechanism 41 when the aluminum strapping tape 100 is encountered.

In some alternative embodiments, the cutting device 40 further comprises a collection bin 43 located below the cutter 42.

Limiting device 50

As shown in fig. 1, 9, 10 and 12, the stopper 50 is mounted on the holding body 10 and moves along with the holding body 10. The limiting device 50 is used for stopping the aluminum armor tape 100, and when the cutter 42 of the cutting device 40 cuts the aluminum armor tape 100 and axial force on the aluminum armor tape 100 is inevitably generated, the limiting device 50 is used for limiting the aluminum armor tape 100 to axially move relative to the overhead line 200. The stopper 50 includes: a stopper mechanism 51 and a drive mechanism 52. The stop mechanism 51 comprises two oppositely arranged pinch plates 511, and the two pinch plates 511 are opened or closed through pivoting; the driving mechanism 52 is used for driving the stopping mechanism 51 to vertically move to be close to or far away from the overhead line 200 in the radial direction; wherein: a guide face 5111 is formed on the outer side of the lower portion of the buckle 511, when the driving mechanism 52 makes the stopper mechanism 51 in the closed state move down to contact with the overhead wire 200, the overhead wire 200 forces the two buckles 511 to open by contacting with the guide face 5111, and then the buckles 511 close to make the overhead wire 200 located between the two buckles 511; so that the stop mechanism 51 can stop the end of the aluminum armor tape 100 on the overhead wire 200. Thus, when the whole device moves and the cutting device 40 encounters the aluminum armor tape 100, before the cutting knife 42 of the cutting device 40 cuts the aluminum armor tape 100, the driving mechanism 52 drives the stopping mechanism 51 to move downwards, so that the overhead line 200 is located between the two buckle plates 511, at this time, the two buckle plates 511 are stopped at one end of the aluminum armor tape 100, which is far away from the cutting knife 42, by adjusting the axial position, so that when the cutting knife 42 cuts the aluminum armor tape 100 through axial movement, the aluminum armor tape 100 cannot move relative to the overhead line 200 (or is synchronous to the cutting knife 42) in the whole cutting process, so that the cutting knife 42 can cut the aluminum armor tape 100. After the aluminum armor tape 100 is cut by the cutter 42, the stopper mechanism 51 moves upward by the driving mechanism 52, and the two clips 511 are separated from the overhead wire 200 and stop above the overhead wire 200.

In some alternative embodiments, the two fastening plates 511 of the stopping mechanism 51 are provided with a cutting strip 513 at one end facing the aluminum armor tape 100, as shown in fig. 9 and in combination with fig. 1, after the overhead line 200 is located at the two fastening plates 511, the position of the whole device is adjusted again, so that the cutting strip 513 extends into the gap between the aluminum armor tape 100 and the overhead line 200, so that the gap between the aluminum armor tape 100 and the overhead line 200 is increased, and the aluminum armor tape 100 is cut by the cutter 42.

In some alternative embodiments, as shown in fig. 9 in combination with fig. 1, the end of each of the two buckle plates 511 of the stop mechanism 51 facing the aluminum armor tape 100 is provided with a proximity switch 514, and the proximity switch 514 determines that the buckle plate 511 is in contact with the end by contacting with the end of the aluminum armor tape 100, so as to control the motor 212 of the traveling mechanism 21 to stop moving, and simultaneously control the brake mechanism 30 to brake the whole device.

In some alternative embodiments, as shown in fig. 10 in combination with fig. 1, stop mechanism 51 further includes a frame 512, and two latch plates 511 are pivotally connected to frame 512 via a pivot 515, and the two latch plates 511 are kept closed by a ruler spring 517. That is, both of the two catching plates 511 are opened only after moving down to be in contact with the overhead wire 200 (by the guide faces 5111), and both of the two catching plates 511 are closed by the blade spring 517 when the stopper is above the overhead wire 200. It should be noted that: the purpose of the spring 517 is also that after the overhead line 200 is located between the two clips 511, the spring 517 also acts to close the clips 511 again to facilitate stopping of the aluminum armor tape 100.

In some alternative embodiments, as shown in fig. 11 and 12 in conjunction with fig. 1, the drive mechanism 52 includes: a spring 522 and an electromagnetic mechanism. The spring 522 is provided between the holding body 10 and the frame 512; the electromagnetic mechanism is disposed between the holding body 10 and the frame 512; wherein: the electromagnetic mechanism drives the stopping mechanism 51 to move upwards through the frame 512 by applying a magnetic force, and the spring 522 is compressed; when the magnetic force is removed, the spring 522 is reset and the frame 512 drives the limiting mechanism to move downwards. Specifically, as shown in fig. 11, the electromagnetic mechanism includes a plurality of pairs of electromagnets 521 on which the holding body 10 and the frame body 512 are respectively provided, and when the electromagnets 521 are energized, the paired electromagnets 521 are attracted so that the frame body 512 moves upward, and the spring 522 is compressed; as shown in fig. 12, when the electromagnet 521 is not energized, the spring 522 is returned to move the frame 512 downward.

In some alternative embodiments, as shown in fig. 1, frame 512 extends horizontally for a length to form a barrier 5121; the limiting device 50 further comprises a clamping mechanism; screens mechanism includes: a motor 531 and a rotating arm 533. The motor 531 is provided on the holding body 10; a rotating arm 533 which is driven to rotate horizontally by the motor 531; wherein: when the electromagnetic mechanism applies a magnetic force to move the frame 512 upward, the rotating arm 533 rotates horizontally to move its head portion below the stopper 5121, so that the stopper mechanism 51 is held above the overhead wire 200. When it is desired to move the stopper mechanism 51 downward, the head of the rotating arm 533 is rotated away from the stop 5121, and the stopper mechanism 51 is moved downward by the spring 522 to perform a stopper of the end of the aluminum armor tape 100. Preferably, a rotating sleeve 532 is disposed on the motor 531, the tail portion of the rotating arm 533 is connected to the rotating sleeve 532, and the motor 531 drives the rotating sleeve 532 to rotate so as to drive the rotating arm 533 to rotate horizontally. A guide post 515 is fixed to the frame 512, a guide sleeve 11 is provided on the holding body 10, and the upper end of the guide post 515 extends into the guide sleeve 11.

The operation of the above-described device for breaking aluminium armour tape is briefly described as follows:

as shown in fig. 11, when the entire apparatus passes through the aluminum armor tape 100 and the proximity switch 424 on the cutter 42 senses that the cutter 42 is approaching the aluminum armor tape 100, the brake mechanism 30 is caused to apply braking to the entire apparatus.

As shown in fig. 12, the motor 531 of the locking mechanism is controlled to rotate the head of the rotating arm 533 away from the stopper 5121, the stopper mechanism 51 moves downward by the spring force of the driving mechanism 52, and the buckle 511 covers the overhead line 200 by opening and closing the buckle 511, and at this time, the two buckles 511 are opposite to and spaced apart from the front end of the aluminum armor tape 100.

Then, the whole device is retracted by the traveling mechanism 21 for a distance, so that the insert 513 on the buckle plate 511 extends into the space between the aluminum armor tape 100 and the overhead line 200 to increase the gap between the aluminum armor tape 100 and the overhead line 200, when the proximity switch 514 on the buckle plate 511 contacts the aluminum armor tape 100, the buckle plate 511 and the aluminum armor tape 100 are contacted and play a role in stopping and limiting, at this time, the proximity switch 514 enables the traveling mechanism 21 to stop driving the whole device, and the braking mechanism 30 brakes the whole device.

As shown in fig. 13, the motor 411 of the cutting device 40 rotates to make the cutting move forward to perform the cutting action on the aluminum armour tape 100, and the cut portion slides down the upper guide surface 4221 under the action of the guide surface 4221 to be separated from the overhead wire 200, as shown in fig. 14, until the aluminum armour tape 100 is completely cut, the cut aluminum armour tape 100 falls into the collection box 43 under the action of gravity.

After the aluminum armor tape 100 is cut, the filament mother plate 413 under the cutting blade 42 moved forward comes into contact with the proximity switch 45 on the ear plate of the collection box 43, and after the contact with the proximity switch 45, the proximity switch 45 controls the motor 411 to rotate in reverse to retract the cutting blade 42, and when the cutting blade 42 retracts to the rear end of the main body 422 (tile-shaped body) of the cutting blade 42 and the proximity switch 46 provided on the U-shaped plate 441, the proximity switch 46 controls the motor 411 of the driving mechanism 41 of the cutting device 40 to stop operating, and at this time, the cutting blade 42 is reset. Thereby completing the cutting of the aluminum armor tape 100.

The advantages of the device for breaking aluminum armour tape and its accessories provided by the above embodiments are described as follows:

1. the device for breaking the aluminum armor tape can automatically cut and collect the aluminum armor tape 100 on the overhead line 200, and a series of problems caused by manual cutting are avoided.

2. The guide mechanism 22 in the running gear 20 can effectively prevent the entire device from coming off the overhead wire 200, so that the entire device can stably run on the overhead wire 200.

3. The rolling mechanism 23 in the traveling device 20 rolls the aluminum armour tape 100 before cutting by the rolling wheel 231, so as to increase the gap between the aluminum armour tape 100 and the overhead line 200, so that the cutting knife 42 can cut the aluminum armour tape 100.

4. The limiting device 50 utilizes two buckle plates 511 to stop the front end of the aluminum armor tape 100 so as to prevent the aluminum armor tape 100 from moving synchronously with the cutting knife 42 when being cut.

5. The detent mechanism of the position limiter 50 is rotated to the bottom of the stop plate 5121 by the rotating arm 533 to prevent the stop mechanism 51 from moving downward so as to make the stop mechanism 51 away from the overhead line 200 (when the aluminum armor tape 100 is not passed, the stop mechanism 51 is separated from the overhead line 200 to facilitate the movement of the whole device).

6. The limiting mechanism drives the stopping mechanism 51 to move by utilizing the electromagnetic mechanism, so that the space is saved, and the response of the movement of the stopping mechanism 51 is quicker.

7. The brake mechanism 30 can make the response of the friction block faster by using the electromagnetic mechanism as the driving force, thereby making the braking more timely.

8. The front end of the cutter 42 forms a guide surface so that the cut portion of the aluminum armor tape 100 moves up by the guide surface to be separated from the overhead wire 200.

9. When the cutter 42 moves along the overhead wire 200, the bar 44 separates the blade 421 from the overhead wire 200, and further prevents the blade 421 from scratching the conductor.
