The outer surfaces of the first rotating shaft 7 and the second rotating shaft 8 are fixedly connected to a wire feeding wheel 9. The end of the support rod away from the first right-angle seat 4 is provided with a thread matched with the second stop block. After the second stop block is unscrewed from the support rod, the first winding roller 5 can be slid off the support rod, and then the cable can be wound on the first winding roller 5. After reinstalling the first winding roller 5 with the cable on the support rod, one end of the cable is passed between the two wire feeding wheels 9, and the cable can be pushed by starting the driving mechanism.

[0024] like Figure 1-3 As shown, a cutting mechanism is also provided on the upper surface of the support platform 1, and the cutting mechanism is located between the wire feeding wheel 9 and the sleeve 2. The cutting mechanism includes a first shell 10 fixedly connected to the upper surface of the support platform 1, and two symmetrical reciprocating screws 11 are rotatably installed inside the first shell 10, and the ends of the two reciprocating screws 11 close to each other are fixedly connected by a round block, and the outer surfaces of the two reciprocating screws 11 are threadedly connected with a threaded seat 12, and the threaded seat 12 is slidably connected to the first shell 10, and the sides of the two threaded seats 12 close to each other are fixedly installed with cutting knives 13, and the rotation of the reciprocating screw 11 can drive the threaded seat 12 to move back and forth along the reciprocating screw 11, and the movement of the threaded seat 12 can drive the cutting knife 13 to move accordingly. When the two cutting knives 13 move to contact each other, the cable between the two cutting knives 13 can be cut.

[0025] like Figure 1-3 As shown, a driving mechanism is also provided on the upper surface of the support platform 1, and the driving mechanism includes a second right-angle seat 14 fixedly mounted on the upper surface of the support platform 1, a servo motor 15 is mounted on the second right-angle seat 14, a driving shaft 16 is fixedly connected to the output end of the servo motor 15, a first one-way bearing 17 is mounted on the outer surface of the driving shaft 16, a first synchronous wheel 18 is mounted on the first one-way bearing 17, a second synchronous wheel 19 is fixedly connected to the outer surface of the support rod, and the second synchronous wheel 19 and the first synchronous wheel 18 are connected through a first synchronous belt transmission, the servo motor 15 has a self-locking function, when the servo motor 15 is controlled to rotate forward, the servo motor 15 can drive the driving shaft 16 to rotate forward, the forward rotation of the driving shaft 16 can drive the first one-way bearing 17 and the first synchronous wheel 18 to rotate accordingly as a whole, the rotation of the first synchronous wheel 18 can drive the second synchronous wheel 19 and the first winding roller 5 to rotate, and the first winding roller 5 can release the cable when it rotates.

[0026] like Figure 2 and Figure 3As shown, a second one-way bearing 20 is installed on the outer surface of the drive shaft 16, and a third synchronous wheel 21 is installed on the second one-way bearing 20. A fourth synchronous wheel 22 is fixedly connected to the outer surface of the second rotating shaft 8, and the fourth synchronous wheel 22 and the third synchronous wheel 21 are connected by a second synchronous belt transmission. A third rotating shaft 23 is rotatably installed on one of the support seats 6, and the outer surfaces of the third rotating shaft 23 and the second rotating shaft 8 are fixedly connected with a fifth synchronous wheel 24, and the two fifth synchronous wheels 24 are connected by a third synchronous belt transmission. The outer surfaces of the third rotating shaft 23 and the first rotating shaft 7 are A gear 25 is fixedly connected, and the two gears 25 are meshed with each other. The second one-way bearing 20 and the first one-way bearing 17 have the same rotation direction, so that the positive rotation of the drive shaft 16 can drive the second one-way bearing 20 and the third synchronous wheel 21 to rotate accordingly as a whole. The rotation of the third synchronous wheel 21 can drive the fourth synchronous wheel 22, the second rotating shaft 8, the third rotating shaft 23 and the first rotating shaft 7 to rotate simultaneously. The rotation of the first rotating shaft 7 and the second rotating shaft 8 can drive the two wire feeding wheels 9 to rotate in the direction of the sleeve 2 at the same time. The two wire feeding wheels 9 rotate in the direction of the sleeve 2 to push the cable.

[0027] like Figure 2 and Figure 3 As shown, a third one-way bearing 50 is installed on the outer surface of the driving shaft 16, and a sixth synchronous wheel 51 is installed on the third one-way bearing 50. A seventh synchronous wheel 52 is fixedly connected to the outer surface of one of the reciprocating screw rods 11. The seventh synchronous wheel 52 and the sixth synchronous wheel 51 are connected through a fourth synchronous belt transmission. The third one-way bearing 50 and the second one-way bearing 20 rotate in opposite directions. Therefore, when the driving shaft 16 rotates forward, it will only drive the third one-way bearing 50 to rotate idly, and the sixth synchronous wheel 51 will not rotate accordingly. Therefore, in the process of pushing the cable, the cutting knife 13 will not move. After the cable is pushed, the servo motor 15 is controlled to reverse, and the servo The motor 15 can drive the driving shaft 16 to rotate in the opposite direction. The opposite rotation of the driving shaft 16 can drive the third one-way bearing 50 and the sixth synchronous wheel 51 to rotate accordingly as a whole. The rotation of the sixth synchronous wheel 51 can drive the seventh synchronous wheel 52 and the two reciprocating screw rods 11 to rotate. The rotation of the two reciprocating screw rods 11 can drive the threaded seat 12 to move back and forth along the reciprocating screw rods 11. The movement of the threaded seat 12 can drive the cutting knife 13 to move accordingly. When the two cutting knives 13 move to contact each other, the cable between the two cutting knives 13 can be cut. After cutting the cable, the reciprocating screw rod 11 continues to rotate to drive the threaded seat 12 to move in the opposite direction to the initial state, and then the servo motor 15 can be turned off.

[0028] like Figure 1-4 and Figure 7As shown, two semicircular covers 49 are arranged outside the sleeve 2, and the semicircular covers 49 are connected to the clamping plate 44 through a connecting plate 48. A second slide groove for the connecting plate 48 to slide horizontally is provided inside the sleeve 2. The upper surface of the support platform 1 is fixedly connected to the first support plate 38. The upper surface of the first support plate 38 is provided with a support mechanism for supporting the sleeve 2. The support mechanism includes a Z-shaped plate 42 fixedly connected to the upper surface of the first support plate 38. The upper surface of the Z-shaped plate 42 is fixedly connected to two third support plates 43. The two third support plates 43 are fixedly connected to the sides away from each other. A connecting seat 26 is fixedly connected, and two bending rods 27 are fixedly connected to one side of the two connecting seats 26 close to the sleeve 2, and the bending rod 27 is located between the second shell 46 and the semicircular cover 49. The bending rod 27 is a column with horizontal ends and an outwardly inclined middle part. When the sleeve 2 is pulled to reset, the bending rod 27 will first be inserted between the second shell 46 and the semicircular cover 49, and then when the semicircular cover 49 gradually moves to the bending position of the bending rod 27, the bending rod 27 will gradually drive the semicircular cover 49 to move toward the center and open the semicircular cover 49, thereby achieving the center positioning of the semicircular cover 49 and the sleeve 2.

[0029] like Figure 4-6 and Figure 8-10As shown, the outer surface of the sleeve 2 is fixedly connected to two symmetrical second shells 46, and two clamping plates 44 are movably arranged inside the sleeve 2. The ends of the two clamping plates 44 away from each other are fixedly connected with plug posts 45, and the ends of the plug posts 45 away from the clamping plates 44 slide through the sleeve 2 and extend into the interior of the second shell 46. The outer surfaces of the two plug posts 45 located in the inner parts of the two second shells 46 are fixedly connected to the first rectangular plates 29, and the outer surfaces of the two first rectangular plates 29 are fixedly connected to the first springs 30, and the other ends of the first springs 30 are fixedly connected to the inner walls of the second shells 46. The interiors of the two second shells 46 are provided with release limit mechanisms, and the release limit mechanisms are connected to the pull-back mechanism. The release limit mechanisms include fixed A second rectangular plate 31 is connected to the upper surface of the plug post 45, and a first wedge block 32 is fixedly connected to a side of the second rectangular plate 31 close to the sleeve 2. A second spring 34 is fixedly connected to the inside of the second shell 46, and one end of the second spring 34 is fixedly connected to a third rectangular plate 33, and the third rectangular plate 33 is slidably connected to the inside of the second shell 46. The second shell 46 is provided with a third sliding groove for the third rectangular plate 33 to slide horizontally. A second wedge block 35 adapted to the first wedge block 32 is fixedly connected to the upper surface of the third rectangular plate 33, and a baffle 36 is fixedly connected to a side of the second wedge block 35 away from the second spring 34. Anti-skid pads 47 are installed inside the two clamping plates 44. By setting the anti-skid pads 47, the clamping plate 44 and the cable can be increased. The friction between them improves the fixing effect. A first sliding groove is provided inside the sleeve 2 for the plug post 45 to slide horizontally. After one end of the cable passes through the protective tube, the staff holds the shell 3 and starts the pull-back mechanism to pull the third rectangular plate 33 to move. The movement of the third rectangular plate 33 can drive the second wedge block 35 to move accordingly and compress the second spring 34. The movement of the second wedge block 35 can squeeze the first wedge block 32 to move outward. The movement of the first wedge block 32 can drive the plug post 45 and the clamping plate 44 to move accordingly and compress the first spring 30. The clamping plate 44 moves outward to release the cable. When the third rectangular plate 33 moves to the maximum extent, the second wedge block 35 is no longer in contact with the first wedge block 32. At this time, under the action of the first spring 30 , the first wedge block 32 will move to abut against the stop bar 36, so as to limit the second wedge block 35, thereby preventing the clamping plate 44 from re-clamping the cable due to the loosening of the wire rope 41 during the movement of the pulling sleeve 2. When the sleeve 2 moves to the bending rod 27 and inserts between the second shell 46 and the semicircular cover 49, the sleeve 2 continues to be pulled. The bending rod 27 will gradually drive the semicircular cover 49 to move toward the center and open the semicircular cover 49. The semicircular cover 49 moves outward and can drive the clamping plate 44 to move accordingly again. When the sleeve 2 is reset to the initial position, the semicircular cover 49 will move outward to the maximum extent. At this time, the first wedge block 32 and the second wedge block 35 are flush with each other and there is a gap between them to ensure that when clamping the cable,The first wedge block 32 will not block the second wedge block 35.

[0030] like Figure 1-3 As shown, a pulling mechanism for pulling the sleeve 2 for resetting is provided on the right side of the first support plate 38, and the pulling mechanism includes a support frame fixedly connected to the upper surface of the support platform 1, and a double-axis motor 37 is installed on the support frame. The two output ends of the double-axis motor 37 are fixedly installed with second winding rollers 40, and the ends of the two second winding rollers 40 that are away from each other are rotatably installed with a second support plate 39, and the second support plate 39 is fixedly connected to the right side of the first support plate 38. Steel wire ropes 41 are wound around the two second winding rollers 40, and the other end of the steel wire rope 41 slides through one side of the second shell 46 and is fixedly connected to the third rectangular plate 33. The double-axis motor 37 has a self-locking function. A circular hole for the second shell 46 to slide is opened inside the second shell 46. When the double-axis motor 37 is started, the double-axis motor 37 can drive the second winding rollers 40 to rotate. When the second winding rollers 40 are driven to rotate forward, The wire rope 41 is wound up, and when the second winding roller 40 is driven to rotate in the opposite direction, the wire rope 41 can be released. While releasing the wire rope 41, the cable is pushed to move in the direction of the sleeve 2. Releasing the wire rope 41 will release the tension limit on the sleeve 2, and the third rectangular plate 33 and the second wedge block 35 will move in the direction away from the support platform 1. Under the action of the elastic force of the first spring 30, the semicircular cover 49 will also gradually slide along the curved part of the curved rod 27 in the direction away from the support platform 1. When the second wedge block 35 moves to the maximum extent in the direction away from the support platform 1, the first wedge block 32 and the clamping plate 44 will also move to the maximum extent in the direction of the cable, so that the two clamping plates 44 will clamp the cable. At this time, the inclined surface of the first wedge block 32 contacts the inclined surface of the second wedge block 35. Then, continue to push the cable to make the sleeve 2 and the semicircular cover 49 separate from the curved rod 27 and enter the interior of the protective tube.

[0031] like Figure 2 As shown, the left end of the sleeve 2 is fixedly connected to the shell 3, and the sleeve 2 and the two semicircular covers 49 are both located inside the shell 3, and the fixed pulley 28 for guiding and supporting the wire rope 41 is rotatably installed on the sides of the two third support plates 43 close to each other.

[0032] Working principle: When pushing the cable, first pass one end of the cable between the two wire feeding wheels 9, and then control the servo motor 15 to rotate forward and the dual-axis motor 37 to rotate reversely. The servo motor 15 can rotate forward to push the cable to move in the direction of the sleeve 2, and the dual-axis motor 37 can release the wire rope 41 by reversing. Releasing the wire rope 41 will release the tension limit on the sleeve 2, and the third rectangular plate 33 and the second wedge block 35 will move in the direction away from the support platform 1. Under the action of the elastic force of the first spring 30, the semicircular cover 49 will also gradually slide along the curved part of the bent rod 27 away from the support platform 1. When the second wedge block 35 moves to the maximum extent in the direction away from the support platform 1, the first wedge block 32 and the clamping plate 44 will also move to the maximum extent in the direction of the cable, so that the two clamping plates 44 will clamp the cable, and then continue to push the cable to make the sleeve 2 and the semicircular cover 49 separate from the bent rod 27 and enter the interior of the protective tube.

[0033] After one end of the cable passes through the protective tube, one of the staff members moves here to hold the shell 3 and operate the passed cable, and the other staff member turns off the servo motor 15 at the initial position and controls the dual-axis motor 37 to rotate forward. The dual-axis motor 37 rotates forward to reel in the wire rope 41, so that the wire rope 41 will pull the third rectangular plate 33 to move. The movement of the third rectangular plate 33 can drive the second wedge block 35 to move accordingly and compress the second spring 34. The movement of the second wedge block 35 can squeeze the first wedge block 32 to move outward. The movement of the first wedge block 32 can drive the plug column 45 and the clamping plate 44 to move accordingly and compress the first spring 30. The clamping plate 44 moves outward to release the cable. When the third rectangular plate 33 moves to the maximum extent, the second wedge block 35 is no longer in contact with the first wedge block 32. At this time, when the first spring Under the action of 30, the first wedge block 32 will move to press against the stop bar 36, so as to limit the second wedge block 35, thereby preventing the clamping plate 44 from re-clamping the cable due to the loosening of the wire rope 41 during the movement of the pulling sleeve 2, and then continuing to reel in the wire rope 41 can drive the third rectangular plate 33 and the sleeve 2 to return to the original path. When the sleeve 2 moves to the bending rod 27 and is inserted between the second shell 46 and the semi-circular cover 49, in the process of continuing to pull the sleeve 2, the bending rod 27 will gradually drive the semi-circular cover 49 to move toward the center and open the semi-circular cover 49. The outward movement of the semi-circular cover 49 can drive the clamping plate 44 to move accordingly again. When the sleeve 2 is reset to the initial position, the semi-circular cover 49 will move outward to the maximum extent, and then the servo motor 15 can be controlled to reverse and cut the cable.
