[0033] refer to Figure 1-Figure 9 , this embodiment provides an auxiliary device for pulling cables and wires, including: a base 1, a lifting frame 2, a winding wheel 3, a guide wheel 4 and a driving assembly 5;

[0034] The lifting frame 2 includes a fixed part 21 fixedly connected to the base 1, and a movable part 22 movably connected to the fixed part 21 along the height direction of the lifting frame 2; the guide wheel 4 is arranged on the movable part 22, and the winding wheel 3 is arranged on the base 1;

[0035] The movable part 22 drives the guide wheel 4 to move up and down along the height direction relative to the winding wheel 3 to change the distance between the guide wheel 4 and the winding wheel 3, thereby changing the height of the auxiliary equipment, so as to adjust the height to be close to the outlet of the threading rope 6, or parallel to the outlet of the threading rope 6. The best is to adjust the auxiliary equipment to be higher than the outlet of the threading rope 6. The threading rope 6 at the outlet section is generally arranged along the height direction of the wall. If the height of the auxiliary equipment is lower than the outlet, that is, the threading rope 6 is pulled downward at an angle greater than ninety degrees relative to the wall, it is easy to cause friction between the threading rope 6 and the wall. The lower the auxiliary equipment is below the outlet of the threading rope 6, the easier it is to rub the threading rope 6 and cause damage.

[0036] The driving assembly 5 is used to drive the winding wheel 3 to rotate around its own axis; the guide wheel 4 is used to guide the threading rope 6 of the cable to be stretched to a direction perpendicular to the axis of the winding wheel 3; the threading rope 6 of the cable to be stretched is fixed to the winding wheel 3 after passing around the guide wheel 4.

[0037] The above-mentioned auxiliary equipment for pulling cables and wires can move the guide wheel 4 to a suitable height by adjusting the height of the lifting frame 2, and the wires to be stretched are passed around the guide wheel 4 and fixed on the winding wheel 3, and then the driving component 5 can be used to drive the winding wheel 3 to rotate, and then the threading rope 6 coming out of the bottom box is pulled and wound on the winding wheel 3, and then the threading rope 6 pulls the cables and wires to be stretched in the bottom box, thereby completing the purpose of pulling the cables and wires.

[0038] In order to fix the threading rope 6 on the winding wheel 3, so that the threading rope 6 is wound around the winding wheel 3 when the winding wheel 3 rotates, and then the cable wire is pulled. The surface of the winding wheel 3 is provided with a spirally distributed winding groove 31; one end of the winding groove 31 is provided with a pressing block 32, and the pressing block 32 is used to fix the threading rope 6 of the cable wire to be stretched in the winding groove 31. The pressing block 32 and the winding wheel 3 are fixed by bolts. When in use, the bolts are first loosened, and the threading rope 6 or one end of the threading rope 6 is set under the pressing block 32, and then the bolts are tightened, so that the threading rope 6 can be squeezed by the pressing block 32, so that the threading rope 6 is fixed in the winding groove 31.

[0039] In this embodiment, the driving assembly 5 includes a motor 51, and a rotating shaft 33 is extended axially from one end surface of the winding wheel 3, and the rotating shaft 33 is fixedly connected to the output rotating shaft of the motor 51 through a coupling 52. In addition, the winding wheel 3 is provided with bearings 32 at both ends along the axial direction, and the surface of the base 1 is provided with a bearing seat 11 for fixing the bearing 32. In this way, the winding wheel 3 can be fixed on the base 1. Similarly, the surface of the base 1 is also provided with a platform 12 for fixing the motor 51.

[0040] The coupling 52 is used to connect the two rotating shafts 33 together. It is a conventional part in the prior art and will not be described in detail in this embodiment.

[0041] In order to realize the lifting and lowering of the lifting frame 2, the fixed part 21 and the movable part 22 of the lifting frame 2 in this embodiment are respectively rectangular frames, wherein the upper end surface of the rectangular frame of the fixed part 21 is provided with a slot for plugging and matching with the movable part 22, and the slot and the part of the movable part 22 inserted into the slot are respectively provided with a plurality of connection holes 23; a connecting piece connects the connection holes 23 of the movable part 22 with different connection holes 23 in the slot. In this embodiment, the connecting piece is a latch 24, and the fixed part 21 and the movable part 22 can be connected together by passing the latch 24 through the connection holes 23 of the fixed part 21 and the movable part 22, and the connection between the fixed part 21 and the movable part 22 can be released after the latch 24 is pulled out, so as to further adjust the relative position of the fixed part 21 and the movable part 22.

[0042] The lifting frame can also be lifted by providing a locking structure on the fixed part 21, such as a knob and a bolt. Rotation can lock or release the fixed part 21 and the movable part 22. The bolt can lock the fixed part 21 at different positions of the movable part 22 to change the height of the auxiliary equipment.

[0043] Since the movable part 22 is also a rectangular frame, a U-shaped opening is provided on the top of the movable part 22 , and the guide wheel 4 is connected to the side wall of the U-shaped opening through the optical axis 41 .

[0044] In addition, for the convenience of users, the sides of the fixed part 21 and the movable part 22 are respectively provided with anti-collision blocks 25. In this way, when in use, the sides of the fixed part 21 and the movable part 22 can be supported against the wall through the anti-collision blocks 25, and the auxiliary device can be used normally for traction.

[0045] The auxiliary device is static when in use, but needs to be able to be easily moved to a position where traction is required, so the base 1 is provided with a walking wheel 13 on one side along the length direction, and the base 1 is provided with a support column 14 on the other side along the length direction. Under normal circumstances, the support column 14 is in contact with the base 1. When the auxiliary device needs to be moved, one side of the base 1 is tilted to separate the support column 14 from the ground, and the walking wheel 13 can be used for normal walking. In order to facilitate the user to tilt the base 1 and move the auxiliary device, a handrail 15 is also provided on one side of the base 1 where the walking wheel 13 is provided. In addition, a switch 16 for operating the drive assembly 5 is provided on the handrail 15.

[0046] When in use, since the cable and wire are soft and difficult to be threaded into the wire tube 7, the threading rope 6 with a harder material is first passed through the wire tube 7, and the wire tube 7 is buried in the wall. Then one end of the threading rope 6 is connected to the cable and wire, and the other end of the threading rope 6 passes through the guide wheel 4 of the auxiliary device and is guided to the winding wheel 3 by the guide wheel 4. After starting the motor 51, the movement of the threading rope 6 drives the cable and wire to pass through the wire tube 7, making it easier for the cable and wire with a softer material to pass through the wire tube 7. The details are as follows:

[0047] The user presses the handrail 15 to tilt the front end of the base 1 so that only the running wheel 13 is on the ground, and uses the running wheel 13 to move the auxiliary device to the threading position. Adjust the height of the lifting frame 2, and connect the guide wheel 4 and the movable part 22 with the optical axis 41. Then pass the threading rope 6 through the wheel groove 42 of the guide wheel 4 to the winding wheel 3. The threading rope 6 is fixed to the winding wheel 3 by the pressing block 32. Adjust the threading machine so that the anti-collision block 25 is close to the wall, and start the motor 51 switch on the handle to pull the wires and cables.

[0048] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
