[0002] After the building electrical lines are pre-buried in wire tubes, a tape is pre-placed in the wire tube for guiding the cable into the wire tube later. The tape is generally made of steel wire. After the building pipeline is buried later, the cable is pulled by the steel wire for threading. When it is necessary to guide the cable through the steel wire as a tape, one end of the cable is generally tied to one end of the steel wire, and then the steel wire is pulled from the other end of the steel wire to pull the cable into the wire tube. In the process of using the cable tape to pull it through, because the wire tube is not completely straight buried in the building, when the cable is pulled by the tape, due to the angle, the side wall of the cable will rub against the wire tube, and then in the process of pulling the cable through the steel wire, the operation will be more laborious, which increases the labor intensity of the operator and reduces the cable threading efficiency. Therefore, a building cable threading auxiliary device is proposed to address the above problems. Utility Model Content

Example

[0022] like Figure 1 and Figure 3As shown, in order to solve the problem that it is inconvenient to determine the angle at which the fixed tube 5 drives the guide wheel 7 to rotate when the angle of the guide wheel 7 in the fixed tube 5 is adjusted according to the cable's passing-out orientation, a scale ring 8 is fixedly connected to the right end of the support plate 6, a pointer 9 is provided on the inner side of the scale ring 8, and the pointer 9 is fixedly connected to the fixed tube 5. When the angle of the guide wheel 7 in the fixed tube 5 is adjusted according to the cable's passing-out orientation, it is convenient to determine the angle at which the fixed tube 5 drives the guide wheel 7 to rotate by observing the angle at which the pointer 9 points to the scale ring 8 driven by the fixed tube 5. Example

[0023] like Figure 1-3 As shown, in order to solve the problem that it is inconvenient to adjust the angle of the guide wheel 7 in the fixed tube 5 according to the cable outlet orientation, a fixing sleeve 10 is rotatably connected to the left end of the outer side of the fixed tube 5, and the fixing sleeve 10 is fixedly connected to the fixing cover 1, and a worm 11 that penetrates the fixing sleeve 10 is rotatably connected to the top of the fixing sleeve 10, and a worm wheel 12 is meshedly connected to the outer side of the worm 11, and the worm wheel 12 is fixedly connected to the fixed tube 5. By rotating the worm 11 to mesh the worm wheel 12, the worm wheel 12 further drives the guide wheel 7 in the fixed tube 5 to rotate, which facilitates the adjustment of the angle of the guide wheel 7 in the fixed tube 5 according to the cable outlet orientation. Example

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, in order to solve the problem that it is inconvenient to adjust the height of the fixed tube 5, the guide wheel 7 and the support plate 6 according to the cable outlet height, the outer side of the fixed cover 1 is fixedly connected to a fixed frame 13 through a connecting block, and the bottom end of the inner side of the fixed frame 13 is slidably connected to a bracket 14, and the top end of the inner side of the bracket 14 is spirally connected to an adjusting threaded shaft 15, and the adjusting threaded shaft 15 is rotatably connected to the fixed frame 13. By controlling the spiral connection between the adjusting threaded shaft 15 and the bracket 14, the fixed frame 13 is further slid up and down, which facilitates the adjustment of the height of the fixed tube 5, the guide wheel 7 and the support plate 6 according to the cable outlet height. Example

[0027] In this embodiment, before the cable is threaded through the device, the sprocket 16 and the chain 17 are meshed, and the handle 18 is used to control the adjustment of the threaded shaft 15 and the bracket 14 to further make the fixed frame 13 slide up and down continuously. At this time, the height of the fixed tube 5, the guide wheel 7 and the support plate 6 can be adjusted according to the cable's passing height. After the adjustment, when the device assists the operator to thread the cable, the angle of the guide wheel 7 in the fixed tube 5 is first adjusted according to the cable's passing direction. At this time, the worm 11 is rotated to engage the worm wheel 12 so that the worm wheel 12 drives the guide wheel 7 in the fixed tube 5 to rotate, and the fixed tube 5 drives the guide wheel 7 to rotate. When the angle of the needle 9 on the scale ring 8 is ninety degrees and the guide wheel 7 can guide the cable in the specified outlet direction, the steel wire 4 passes through the wire tube and is connected to the cable, and then the device is pushed to make the support plate 6 contact with the building to ensure that the fixed block 21 is inserted into the wiring groove, and then the fixed threaded shaft 20 is rotated to be spirally connected with the fixed block 21 to position the support plate 6 outside the wiring groove, and finally the motor 2 is started by the controller 19 to drive the reel 3 to reel the steel wire 4.
