Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Example 1: Please refer to Figure 1-4 The utility model provides a technical solution: a cable threading tool for a cable trough of a port equipment yard bridge, comprising a glass fiber reinforced plastic threader 1, a threader cable 2 is arranged on the glass fiber reinforced plastic threader 1, a threading block 3 is movably installed on the threading cable 2, a threading structure is installed on the threading block 3, a threading head 4 is installed on the threading structure, a connecting structure is arranged on the threading head 4, a threading ring 5 is fixedly installed on the threading block 3, and an auxiliary bending structure is installed on the threaded ring 5;
[0025] The threading structure includes a cable trough 31, which is provided on the threading block 3. The threader cable 2 is movably installed in the cable trough 31. The threading block 3 is provided with a plurality of threading troughs 32. The threading block 3 is threaded with a plurality of first hexagon socket bolts 33. One end of the first hexagon socket bolt 33 is located in the corresponding threading trough 32. Two second hexagon socket bolts 34 are threadedly installed on the threading block 3. One end of the two second hexagon socket bolts 34 are both located in the cable trough 31. The two second hexagon socket bolts 34 are both in contact with the threader cable 2.
[0026] The wiring structure includes a hanging groove 41, which is opened on the threading head 4. The threading head 4 is provided with an arc surface 42. The cable to be pulled can be inserted into the threading groove 32, and then the first hexagon socket bolt 33 at the corresponding position is rotated to fix the cable. The first hexagon socket bolt 33 can be rotated and moved to different degrees, so that cables of different specifications can be fixed. The cable groove 31 can be used to insert the threader cable 2, and the two second hexagon socket bolts 34 are rotated to fix the threader cable 2. After connecting the threader cable 2 and the cable, the mask 51 is re-sleeved on the threading head 4, the threading head 4 is inserted into the pipe, and the fiberglass threader 1 is used to release the threader cable 2 and extend it into the pipe. The threading head 4 is driven by the threader cable 2 to move in the pipe. During the movement, the threading head 4 can turn along the inner wall of the pipe corner through the arc surface 42. After passing through the pipe, the hook can be used to hook the hanging groove 41 on the threading head 4 to pull out the threading head 4 and the cable.
[0027] In order to be able to connect and fix the cable and the threader cable 2, two first threaded holes 35 are provided on the inner wall of the threading block 3, and the two first threaded holes 35 are connected to the cable groove 31. Two second hexagon socket bolts 34 are threadedly installed in the two first threaded holes 35 respectively. The inner wall of the threading block 3 is provided with multiple second threaded holes 36, and the second threaded hole 36 is connected to a corresponding threading groove 32. The first hexagon socket bolt 33 is threadedly installed in the second threaded hole 36. Rotate the first hexagon socket bolt 33 at the corresponding position, and the rotating first hexagon socket bolt 33 will rotate and move in the corresponding second threaded hole 36. Rotate the two second hexagon socket bolts 34, and the second hexagon socket bolts 34 will rotate and move in the corresponding first threaded hole 35.
[0028] The working principle is as follows: by rotating the mask 51, the mask 51 slides on the threaded collar 5 through the cooperation with the threaded mounting groove 55, and finally the mask 51 is separated from the threaded collar 5, at which time the restriction on the mask 51 can be released, and then the mask 51 is pulled, and the mask 51 moves on the threading head 4 through the mounting hole 57, and finally the mask 51 is pulled out from the threading head 4, at which time the first hexagon socket bolt 33 and the second hexagon socket bolt 34 are exposed, and the cable to be pulled can be inserted into the threading groove 32, and then the first hexagon socket bolt 33 at the corresponding position is rotated, and the rotating first hexagon socket bolt 33 is in the corresponding The first hexagon socket bolt 33 is rotated and moved in the second threaded hole 36 of the cable, so that the moved first hexagon socket bolt 33 finally abuts on the cable, completing the fixation of the cable, and the first hexagon socket bolt 33 can be rotated and moved to different degrees, so that cables of different specifications (8 square, 10 square, 16 square) can be fixed, and the cable groove 31 can be used to insert the threader cable 2. After the threader cable 2 is inserted into the cable groove 31, the two second hexagon socket bolts 34 are rotated, and the second hexagon socket bolts 34 will rotate and move in the corresponding first threaded holes 35, so that the second hexagon socket bolts 34 abut on the threader cable 2, completing the fixation with the threader cable 2 After the threading device cable 2 and the cable are connected, the shield 51 is re-sleeved on the threading head 4 and rotated so that the shield 51 is re-screwed on the threaded collar 5 through the threaded installation groove 55 to complete the reinstallation of the threaded collar 5. The threaded collar 5 after installation can shield the first hexagon socket bolt 33 and the second hexagon socket bolt 34 to prevent the first hexagon socket bolt 33 and the second hexagon socket bolt 34 from rotating and loosening due to friction with the pipe during the threading process. Then, the threading head 4 is inserted into the pipeline, and the fiberglass threader 1 is used to release the threader cable 2 and extend it into the pipeline. The fiberglass threader 1 can be classified into φ4 in rod diameter .5mm, 10m long threader assists in threading, and the threading head 4 is driven by the threader cable 2 to move in the pipe. When encountering a corner, the threading head 4 will contact the inner wall of the corner. The arc surface 42 and the inclined surface 54 can reduce the friction with the inner wall of the pipe, so that the threading head 4 can turn along the inner wall of the pipe corner through the arc surface 42 during movement. During the turning process, the roller 53 on the fixed seat 52 will contact and rotate with the inner wall of the pipe, making the threading smoother. After passing through the pipe, the hook can be used to hook the hanging groove 41 on the threading head 4 to pull out the threading head 4 and the cable.

The mask 51 can be pulled out from the threading head 4 by rotating the mask 51. At this time, the first hexagon socket bolt 33 and the second hexagon socket bolt 34 can be exposed for installing the cable. The mask 51 can be re-sleeved on the threading head 4 and rotated to reinstall the threaded collar 5. The installation position of the mask 51 can be limited by setting the retaining ring 56. After installation, the threaded collar 5 can block the first hexagon socket bolt 33 and the second hexagon socket bolt 34 to avoid rotation and loosening due to friction with the pipe during the threading process. During the turning process, the roller 53 on the fixed seat 52 will contact and rotate with the inner wall of the pipe, making the threading smoother. The remaining features are the same as those in Example 1.
