DETAILED DESCRIPTION

[0024] To facilitate the understanding of the present invention, the present application will be described more comprehensively below with reference to the relevant drawings; the drawings show preferred embodiments of the present invention, but the present invention can be implemented in many different forms and is not limited to the embodiments described herein; on the contrary, the purpose of providing these embodiments is to enable a more thorough and comprehensive understanding of the disclosed content of the present invention.

[0025] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are only for illustrative purposes and do not represent the only implementation method.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the present invention are only for the purpose of describing specific implementation methods and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] like Figures 1 to 7 As shown, the present application provides a novel column retracting winch, including a base 100, a vehicle body 200 on the base 100, the vehicle body 200 including a drum 210, a rope 220 wound around the drum 210, and a primary cleaning component 300 and a secondary cleaning component 400, the primary cleaning component 300 is used to clean the rope 220 being wound, and the secondary cleaning component 400 is used to clean the rope 220 on the drum 210;

[0028] The primary cleaning assembly 300 includes a return-shaped member 310 fixed to one side of the reel 210, the return-shaped member 310 has a limiting function for the reeled rope 220, and the other side of the return-shaped member 310 is movably connected to a follower brush assembly 320, one end of the rope 220 movably passes through the return-shaped member 310 and the follower brush assembly 320 and then extends outward, and the follower brush assembly 320 and the rope 220 movably conflict with each other;

[0029] The secondary cleaning assembly 400 includes a wire roller brush 410 , and the wire roller brush 410 and the drum 210 are in active contact with each other.

[0030] To be further described in detail: by adopting the primary cleaning component 300 and the secondary cleaning component 400, the rope 220 being wound and the rope 220 already wound on the drum 210 can be cleaned successively, thereby reducing dust or dirt on the rope 220, thereby reducing the running resistance during the winding or unwinding process and increasing the service life of the rope 220.

[0031] Specifically, the primary cleaning assembly 300 is inclined, and the inclination direction of the primary cleaning assembly 300 is consistent with the inclination direction of the rope 220 .

[0032] To further explain in detail: the primary cleaning assembly 300 and the rope 220 have the same inclination direction, which can reduce the wear of the primary cleaning assembly 300 during the winding and winding of the rope 220 and extend the service life of the primary cleaning assembly 300.

[0033] Specifically, the follower brush assembly 320 includes a U-shaped plate 321, which is movably arranged on the return-shaped member 310. A connecting column 322 is provided on one side of the return-shaped member 310. Annular rollers 323 are fixed on both sides of the connecting column 322. Cleaning brushes 324 are fixed on the inner sides of the annular rollers 323. The inner ends of the cleaning brushes 324 movably contact with the rope 220. The annular rollers 323 and the U-shaped plate 321 are fixedly connected.

[0034] Further specific description: Through the design of the follower brush assembly 320, the rope 220 being wound can be cleaned of dust or dirt, reducing the situation where the rope 220 with dust or dirt adhered to it is directly wound around the drum 210, causing dust to be difficult to clean, and reducing the running resistance of the rope 220 when it is retracted and released.

[0035] Specifically, the U-shaped plate 321 and the connecting column 322 are both provided with a slot 325 for the rope 220 to pass through, and the slot diameter of the slot 325 is smaller than the inner diameter of the annular roller 323 .

[0036] Further specific description: Through the above structural design, the U-shaped plate 321 and the connecting column 322 allow the rope 220 to pass through. Since the groove diameter of the groove 325 is smaller than the inner diameter of the annular roller 323, a accommodating space is provided for the cleaning brush 324 after being squeezed, and it will not be excessively squeezed by the rope 220.

[0037] Specifically, sliders are fixed on both sides of the inner wall of the U-shaped plate 321 , and a slide groove cooperating with the slider is provided on the return-shaped member 310 , and the slider is slidably connected inside the slide groove.

[0038] To be further described in detail, the design of the slider and the slide groove can enhance the stability of the U-shaped plate 321 and prevent the U-shaped plate 321 from slipping off the return member 310 .

[0039] Specifically, movable plates 420 are fixed at both ends of the wire roller brush 410, and a square plug-in cylinder 430 is fixed at the top of the base 100 below the reel 210 at a position corresponding to the movable plate 420. There are two square plug-in cylinders 430, and the movable plate 420 is movably connected in the square plug-in cylinders 430 on the same side. A driving member is fixed at one end of the wire roller brush 410.

[0040] To further explain in detail: the driving member is fixed on the moving plate 420 , and the driving member is a motor, and the output shaft of the motor is fixedly connected to one end of the wire roller brush 410 .

[0041] Specifically, a plurality of elastic springs 440 are fixed between the bottom end of the inner wall of the square insert 430 and the bottom end of the movable plate 420. A limiting groove is provided on the inner wall of the square insert 430. A limiting block matching the limiting groove is fixed on the movable plate 420. The limiting block is slidably connected in the limiting groove.

[0042] To further explain in detail: the elastic spring 440 is used in conjunction with the damper; in addition, the limiting groove has a limiting effect on the limiting block, and further has a limiting effect on the moving plate 420, thereby preventing the moving plate 420 from detaching from the square insert 430.

[0043] During actual use of the new column-retracting winch of the embodiment of the present application: when the drum 210 rotates to reel in the line, the rope 220 first passes through the primary cleaning component 300 for cleaning, and the rope 220 passes through the annular roller 323, the connecting column 322, the U-shaped plate 321 and the return member 310. The cleaning brush 324 on the inner side of the annular roller 323 cleans the surface of the rope 220 to reduce dust and dirt adhering to the outside of the rope 220. After the rope 220 is wound around the drum 210, the driving part on the wire roller brush 410 is synchronously started, and the motor of the driving part drives the wire roller brush 410 to rotate, and the rope 220 wound around the drum 210 is cleaned at a secondary level, further reducing dust and dirt, making the rope 220 cleaner, reducing the running resistance of the rope 220 during subsequent winding or unwinding, and increasing the service life of the rope 220.

[0044] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
