Description

Technical Field

[0001] The utility model relates to the technical field of cable laying, in particular to a cleaning mechanism for a cable threading device. Background Art

[0002] The commonly used tool in cable laying is a threading device. An ordinary threading device is mainly made of fiberglass and high-strength resin through high-temperature pultrusion into a fiberglass rod, and the outer surface of the fiberglass rod is made of a sheath layer of high-density polyethylene engineering plastic. The smooth and elastic surface enables the perforator to easily pass through a narrow channel.

[0003] The threading device was originally mainly used for underground traction of walls, and later developed for the traction of optical cable lines in sewers and other lines. It can be used for cleaning of telecommunication pipelines and the laying of optical cables, cables and plastic sub-tubes. When in use, first lead out the fiberglass-covered rod from the guiding wheel, then connect it with the corresponding metal head and insert it into the pipeline. When used for cleaning, the guiding head drives the cleaning tool to clean the pipeline; when used for laying cables, steel wires or iron wires can be brought in first, and then the cables are pulled into the pipe by the steel wires or iron wires.

[0004] Due to the presence of sundries inside the pipeline, the threading device is prone to be contaminated with dust, oil stains, etc. when driving the cable in the channel. When recovering the lead wire after guiding the cable threading, additional cleaning work needs to be carried out on the lead wire, which increases the workload, and it is extremely inconvenient to clean after the lead wire reel is wound up. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a cleaning mechanism for a threading device, which has the advantage of facilitating the cleaning of the traction wire of the threading device.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions:

[0007] A cleaning mechanism for a threading device includes a mounting plate, a connecting frame, a circular brush, a guiding wheel, a first bevel gear, a gear shaft, and a toothed ring. The circular brush is rotatably connected to the mounting plate. The connecting frame is rotatably connected to the mounting plate at the center. A through hole is provided at the hinge joint between the connecting frame and the mounting plate. There are two circular brushes fixedly connected to the connecting frame. There are two guiding wheels, which are rotatably connected to the mounting plate up and down. The first bevel gear is fixedly connected to the lower guiding wheel. The gear shaft is rotatably connected to the mounting plate. Two bevel gears and a spur gear are respectively fixedly connected to both ends of the gear shaft. The second bevel gear meshes with the first bevel gear. The toothed ring is fixedly connected to the connecting frame and meshes with the bevel gear.

[0008] With the above technical solution, the traction wire of the wire pay-off is located between the upper and lower guide wheels, and the through hole of the connecting frame through which it passes is located between two circular brushes. When the traction wire is retracted, pulling the traction wire drives the guide wheels to rotate. The first bevel gear fixedly connected to the lower guide wheel rotates, and the rotation of the first bevel gear drives the second bevel gear meshed with it, causing the spur gear to rotate. The rotating spur gear drives the connecting frame to rotate through the ring gear meshed with it, thereby driving the circular brushes to rotate around the traction wire to clean the whole body of the traction wire.

[0009] Preferably, it further includes a conduit, and the conduit is fixedly connected to the through hole of the connecting frame.

[0010] With the above technical solution, the traction wire passes through the conduit and the through hole and is located between two circular brushes, guiding the traction wire from between the guide wheels to between the circular brushes.

[0011] Preferably, it further includes a rotating arm and a tension spring. The rotating arm is rotatably connected to the mounting plate, the upper guide wheel is rotatably connected to the rotating arm, and both ends of the tension spring are respectively hinged to the mounting plate and the rotating arm.

[0012] With the above technical solution, when the rotating arm is lifted, the two guide wheels move away from each other, and at the same time the tension spring is stretched. Pass the traction wire through the guide wheels, and the tension spring rebounds to pull the rotating arm to drive the upper guide wheel to approach the lower guide wheel, pressing on the traction wire. The elastic force of the tension spring makes the upper guide wheel press tightly on the traction wire, increasing the friction between the traction wire and the guide wheels and better driving the guide wheels to rotate.

[0016] The following are only the preferred embodiments of the present invention, and the scope of protection is not limited to this embodiment. All technical solutions within the idea of the present invention should belong to the scope of protection of the present invention. At the same time, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the scope of protection of the present invention.

[0017] Refer to Figure 1 , Figure 2, A cleaning mechanism for a threader, comprising a mounting plate 1, a connecting frame 2, a circular brush 3, a guide wheel 4, a first bevel gear 5, a gear shaft, a ring gear 6. The circular brush 3 is rotatably connected to the mounting plate 1. The connecting frame 2 is rotatably connected to the mounting plate 1 at the center. A through hole is provided at the hinge joint between the connecting frame 2 and the mounting plate 1. There are two circular brushes 3 fixedly connected to the connecting frame 9. There are two guide wheels 4, which are rotatably connected to the upper and lower parts of the mounting plate 1. The first bevel gear 5 is fixedly connected to the lower guide wheel 4. The gear shaft is rotatably connected to the mounting plate 1. Two second bevel gears 7 and spur gears 8 are respectively fixedly connected to both ends of the gear shaft. The second bevel gear 7 meshes with the first bevel gear 5. The ring gear 6 is fixedly connected to the connecting frame 2. The ring gear 6 meshes with the spur gear 8. The traction line of the wire dispenser is located between the upper and lower guide wheels 4 and passes through the through hole of the connecting frame 2 and is located between the two circular brushes 3. When the traction line is retracted, pulling the traction line drives the guide wheel 4 to rotate. The first bevel gear 5 fixedly connected to the lower guide wheel 4 rotates. The rotation of the first bevel gear 5 drives the second bevel gear 7 meshing with it, and the spur gear 8 rotates. The rotating spur gear 8 drives the connecting frame 2 to rotate through the ring gear 6 meshing with it, so as to drive the circular brush 3 to rotate around the traction line and clean the whole body of the traction line.

[0018] Refer to Figure 1 , It further includes a conduit 9. The conduit 9 is fixedly connected to the through hole of the connecting frame 2. The traction line passes through the conduit 9 and the through hole and is located between the two circular brushes 3, guiding the traction line from between the guide wheels 4 to between the two circular brushes 3.

[0019] Refer to Figure 1 , It further includes a rotating arm 10 and a tension spring 11. The rotating arm 10 is fixedly connected to the mounting plate 1. The upper guide wheel 4 is rotatably connected to the rotating arm 1. Both ends of the tension spring 11 are respectively hinged to the mounting plate 1 and the rotating arm 10. Lift the rotating arm 10, the two guide wheels 4 move away from each other, and at the same time the tension spring 11 is stretched. Pass the traction line through the two guide wheels 4, and the tension spring 11 rebounds to pull the rotating arm 10 to drive the upper guide wheel 4 to approach the lower guide wheel 4 and press the traction line. The elastic force of the tension spring 11 makes the upper guide wheel 4 press the traction line tightly, increasing the friction between the traction line and the guide wheel 4 and better driving the guide wheel 4 to rotate.

[0020] Working principle: Lift the swing arm 10, the two guide wheels 4 move away from each other, and at the same time the tension spring 11 is stretched. Pass the traction wire through the two guide wheels 4, and then the tension spring 11 rebounds to pull the swing arm 10 to drive the upper guide wheel 4 closer to the lower guide wheel 4, pressing on the traction wire. The elastic force of the tension spring 11 causes the upper guide wheel 4 to tightly press the traction wire, increasing the friction between the traction wire and the guide wheel 4 and better driving the guide wheel 4 to rotate. The traction wire passes through the catheter 9 and the through hole between the circular brushes 3, and continues to be conveyed forward. When the traction wire is retracted, pulling the traction wire drives the guide wheel 4 to rotate, and the first bevel gear 5 fixedly connected to the lower guide wheel 4 rotates. The rotation of the first bevel gear 5 is driven by the second bevel gear 7 meshed with it, and the spur gear 8 rotates. The rotating spur gear 8 drives the connecting frame 2 to rotate through the gear ring 6 meshed with it, thereby driving the circular brush 3 to rotate around the traction wire to clean the whole body of the traction wire.
