Specific implementation manner

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-4 , an automatic catenary single-pole removing device, including a vertical channel steel 1, with horizontal channel steels 2 fixed at both the left and right ends of the vertical channel steel 1, and square steels 3 fixed at the lower ends of the horizontal channel steels 2. The forks of the forklift penetrate into the horizontal channel steels 2, and then the vertical channel steel 1 can be lifted, enabling the single pole to enter the vertical channel steel 1. At this time, the single pole is limited by three sides of the vertical channel steel 1;

[0020] A retaining rod 6 is rotatably connected to the front of the right end of the vertical channel steel 1. A fixed plate 4 is fixed to the front of the right end of the vertical channel steel 1. A shaft rod 5 is rotatably connected to the front end of the fixed plate 4. The retaining rod 6 is perpendicularly fixed on the surface of the shaft rod 5. On the other side of the vertical channel steel 1, by rotating the retaining rod 6, the retaining rod 6 rotates through the shaft rod 5, so that the retaining rod 6 lies across the notch of the vertical channel steel 1, preventing the single pole from tilting and moving out of the vertical channel steel 1;

[0021] A chute 7 is opened on the left side of the front end of the vertical channel steel 1. A slider 9 is slidably connected inside the chute 7. A spring 11 is fixedly connected between the upper end of the slider 9 and the top end inside the chute 7. Guide grooves 8 are opened at both the left and right ends of the inner wall of the chute 7. Guide blocks 10 are fixed at both the left and right ends of the slider 9. The guide blocks 10 are located inside the guide grooves 8 and are slidably connected to the guide grooves 8. A lock seat 12 is fixed to the front end of the slider 9. A lock groove 15 is opened at the lower end of the lock seat 12. After the retaining rod 6 lies across the notch of the vertical channel steel 1, the lock seat 12 can be moved downward. The lock seat 12 drives the slider 9 to move downward along the chute 7, and the slider 9 drives the guide blocks 10 to move downward along the guide grooves 8, so that the retaining rod 6 is inserted into the lock groove 15 of the lock seat 12 to prevent the retaining rod 6 from rotating away from the notch of the vertical channel steel 1. At this time, the spring 11 gives the slider 9 a downward force, making the lock seat 12 tightly press the retaining rod 6 and improving the stability of the lock seat 12;

[0022] A ratchet and pawl mechanism is installed at the front end of the lock base 12. A knob 14 is connected to the front part of the ratchet and pawl mechanism. A rectangular groove 24 is opened at the rear end of the slider 9. A threaded sleeve 22 is embedded and rotatably connected to the bottom of the rectangular groove 24. The threaded sleeve 22 is connected to the ratchet and pawl mechanism. The ratchet and pawl mechanism includes a ratchet box 13, a rotating shaft 16, a ratchet 17, a pawl 18, and a spring piece 19. The ratchet box 13 is fixed to the lock base 12. The rotating shaft 16 is rotatably connected inside the ratchet box 13. The front end of the rotating shaft 16 penetrates through the ratchet box 13 and is fixed to the knob 14. The rear end of the rotating shaft 16 is fixed to the threaded sleeve 22. The ratchet 17 is fixed to the outside of the rotating shaft 16. The pawl 18 is located to the right of the ratchet 17 and is rotatably connected inside the ratchet box 13. The pawl 18 is connected to the ratchet 17. The spring piece 19 is connected between the pawl 18 and the inner wall of the ratchet box 13. When the lock base 12 tightly presses the stop lever 6, the knob 14 can be rotated counterclockwise. The knob 14 drives the rotating shaft 16 to rotate counterclockwise. The rotating shaft 16 drives the ratchet 17 to rotate counterclockwise. The connection between the pawl 18 and the ratchet 17 will not prevent the ratchet 17 from rotating counterclockwise, but will prevent the ratchet 17 from rotating clockwise. In this way, after rotating the knob 14 counterclockwise, the knob 14 is self-locked.

[0023] A rectangular block 25 is slidably connected inside the rectangular groove 24. A threaded shaft 23 is fixed to the front end of the rectangular block 25. The front part of the threaded shaft 23 extends into the threaded sleeve 22 and is threadedly connected to the threaded sleeve 22. When the rotating shaft 16 rotates counterclockwise, it can drive the threaded sleeve 22 to rotate counterclockwise. With the threaded cooperation between the threaded sleeve 22 and the threaded shaft 23, the threaded shaft 23 moves backward. The threaded shaft 23 drives the rectangular block 25 to move backward. The upper and lower ends of the rectangular block 25 are in close contact with the upper and lower inner walls of the rectangular groove 24 and slide. Therefore, the rectangular block 25 will not rotate. In this way, the rectangular block 25 moves backward and abuts against the rear end inside the chute 7 to prevent the slider 9 from moving upward, thereby further improving the stability of the lock base 12.

[0024] A pull rope 20 is fixed to the surface of the pawl 18. The end of the pull rope 20 penetrates through the ratchet box 13 and is fixed with a pull head 21. When it is necessary to rotate the ratchet 17 clockwise, the pull head 21 is pulled. The pull head 21 pulls the pull rope 20. The pull rope 20 drives the pawl 18 to rotate. At this time, the pawl 18 is no longer connected to the ratchet 17, and the knob 14 can be rotated clockwise to drive the ratchet 17 to rotate clockwise, which can drive the threaded sleeve 22 to rotate clockwise. With the threaded cooperation between the threaded sleeve 22 and the threaded shaft 23, the threaded shaft 23 moves forward. The threaded shaft 23 drives the rectangular block 25 to move forward. In this way, the rectangular block 25 moves forward and no longer abuts against the rear end inside the chute 7. After that, the slider 9 can move up and down, and then the lock base 12 can be moved upward to separate from the stop lever 6. Finally, the stop lever 6 can be rotated until it no longer blocks the notch of the vertical channel steel 1.

[0025] Working principle: The forks of the forklift penetrate into the horizontal channel steel 2, and then the vertical channel steel 1 can be lifted, enabling the single pole to enter the vertical channel steel 1. At this time, through the three-sided limit of the vertical channel steel 1, and on the other side of the vertical channel steel 1, the lock seat 12 is first pushed upward, and then the shift lever 6 can be rotated. The shift lever 6 rotates through the shaft rod 5, so that the shift lever 6 lies across the notch of the vertical channel steel 1, preventing the single pole from tilting and moving out of the vertical channel steel 1. Subsequently, the lock seat 12 is lowered, causing the shift lever 6 to insert into the lock groove 15 of the lock seat 12 to prevent the shift lever 6 from rotating away from the notch of the vertical channel steel 1. At this time, the spring 11 gives a downward force to the slider 9, pressing the lock seat 12 tightly against the shift lever 6 to improve the stability of the lock seat 12. Then, the knob 14 can be rotated counterclockwise. The knob 14 drives the rotating shaft 16 to rotate counterclockwise, and the rotating shaft 16 drives the ratchet wheel 17 to rotate counterclockwise. After rotating the knob 14 counterclockwise, the knob 14 is self-locked. When the rotating shaft 16 rotates counterclockwise, it can drive the threaded sleeve 22 to rotate counterclockwise. As the threaded sleeve 22 is in threaded engagement with the threaded shaft 23, the threaded shaft 23 moves backward. The threaded shaft 23 drives the rectangular block 25 to move backward. The upper and lower ends of the rectangular block 25 are in close sliding contact with the upper and lower ends of the inner wall of the rectangular groove 24. Therefore, the rectangular block 25 does not rotate. In this way, the rectangular block 25 moves backward and abuts against the rear end inside the chute 7 to prevent the slider 9 from moving upward, thereby further improving the stability of the lock seat 12. Finally, the single pole is removed by the forklift, which can avoid the situation where the single pole falls to the ground and causes the single pole to deform and bend, and will not have a greater impact on the secondary use, and improves the safety.
