Description

Technical Field

[0001] The utility model relates to the technical field related to drag chain cables, in particular to a drag chain cable with dust accumulation resistance. Background Art

[0002] Drag chain cable is a highly flexible special cable that can move back and forth with the drag chain without being easily worn. It is called drag chain cable. It is also commonly called towing cable or tank chain cable.

[0003] Some existing drag chain cables lack protective cleaning devices against external dust and debris during use. As the use time increases, dust will gradually accumulate on the surface of the cable in the chain link. Excessive accumulation will damage the cable surface and affect the service life of the cable.

[0013] The beneficial effects of the utility model are:

[0014] 1. This drag chain cable with dust resistance is provided with chain links, toothed rings, gears, threaded rods, cleaning brushes and branching frames.

[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0026] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the utility model is a drag chain cable with dust accumulation resistance, including a plurality of chain links 1 rotatably connected head to tail, the chain link 1 includes a threading frame 2 and two side plates 3 respectively fixedly installed on both sides of the threading frame 2, the two side plates 3 are rotatably installed with toothed rings 4, two threaded rods 5 are rotatably installed between the two side plates 3, the two side plates 3 are provided with through holes 6, the outer surfaces of the two threaded rods 5 are fixedly installed with gears 7, the two gears 7 are respectively located on both sides of the chain link 1, the gears 7 are meshed with the toothed rings 4 on the adjacent chain links 1 on the same side, the two threaded rods 5 are fixedly installed with fan blades 8, the two fan blades 8 are respectively located in the two through holes 6, the two threaded rods 5 are rotatably installed with cleaning brushes 9, the threading frame 2 is provided with a plurality of threading holes 10, and the threading holes 10 are provided with cleaning brushes 9. A cable body 11 is penetrated, and two cover plates 12 are fixedly installed between the two side plates 3. The two threaded rods 5 are distributed up and down and are located in the same vertical plane. When the drag chain cable moves, the two adjacent chain links 1 that move relative to each other occur, and the toothed rings 4 on both sides respectively drive the gears 7 on the same side to rotate, and the rotation of the gear 7 drives the threaded rod 5 on the same side to rotate. When the threaded rod 5 rotates, it drives the fan blades 8 on the same side to rotate, so that one of the fan blades 8 can inhale fresh air from the outside through the through hole 6 on one side of the chain link 1, and the other fan blade 8 can discharge the dirty air in the chain link 1 through the through hole 6 on the other side of the chain link 1, thereby increasing the air circulation speed in the chain link 1, facilitating the full discharge of dust brushed off by the cleaning brush 9 and the heat dissipation of the cable, thereby improving the cleaning efficiency and the heat dissipation efficiency.

[0027] Among them, the two cover plates 12 are respectively located on the upper and lower sides of the threading frame 2, and the cover plates 12 are rotatably connected to the cover plates 12 on the adjacent chain links 1 on the same side. The two cover plates 12 located on the same chain link 1 are symmetrically distributed and are used to seal the upper and lower sides of the chain link 1. The two cover plates 12 realize the sealing of the upper and lower sides of the chain link 1 and cooperate with the chain link 1 to form a closed drag chain structure, thereby preventing external dust, debris, etc. from entering the chain link 1, thereby achieving the effect of preventing dust accumulation.

[0028] Among them, one side of the cleaning brush 9 is in contact with the threading frame 2, which can guide and limit the movement of the cleaning brush 9 to prevent the cleaning brush 9 from being offset and skewed when moving on the threaded rod 5, thereby ensuring the stability of the movement of the cleaning brush 9.

[0029] Among them, the two cleaning brushes 9 are symmetrically distributed and are respectively located on the upper and lower sides of the cable body 11. The brush surface of the cleaning brush 9 is in contact with the outer surface of the cable body 11. The two threaded rods 5 rotate to drive the two cleaning brushes 9 to move back and forth on the threaded rods 5 and clean the upper and lower sides of the cable body 11, sweeping off the dust adhering to the outer surface of the cable body 11 to prevent dust accumulation on the cable body 11. When the threaded rod 5 rotates, it will drive the fan blades 8 on the same side to rotate, and then fully discharge the dust brushed off by the cleaning brush 9 to prevent dust from accumulating in the chain link 1.

[0030] A mounting bracket 13 is fixedly installed in the through hole 6 , and the mounting bracket 13 is rotatably connected to one end of the threaded rod 5 on the same side. The stability of the threaded rod 5 during rotation can be ensured by providing the mounting bracket 13 .

[0031] During operation, the cable body 11 is inserted into the plurality of chain links 1 through the threading hole 10. When the drag chain cable moves during use, the two adjacent chain links 1 that move relative to each other drive the gears 7 on the adjacent chain links 1 to rotate through the toothed rings 4 on both sides of the chain links 1. The rotation of the gear 7 drives the threaded rod 5 on the same side to rotate. The rotation of the two threaded rods 5 drives the two cleaning brushes 9 to move back and forth on the threaded rod 5 and clean the upper and lower surfaces of the cable body 11, sweeping away the dust adhering to the outer surface of the cable body 11 to prevent dust accumulation on the cable body 11. When the threaded rod 5 rotates, it drives the fan blades on the same side. 8 rotates, so that one of the fan blades 8 inhales fresh air from the outside through the through hole 6 on one side of the chain link 1, and the other fan blade 8 discharges the dirty air in the chain link 1 through the through hole 6 on the other side of the chain link 1, thereby increasing the air circulation speed in the chain link 1, facilitating the full discharge of dust brushed off by the cleaning brush 9 and the heat dissipation of the cable, thereby improving the cleaning efficiency and the heat dissipation efficiency. In addition, by fixing the two cover plates 12 between the two cover plates 12, the two cover plates 12 realize the sealing of the upper and lower sides of the chain link 1 to form a closed drag chain structure, thereby preventing external dust, debris, etc. from entering the chain link 1, thereby achieving the effect of preventing dust accumulation.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
