The wire rope is sleeved on the outer end of the winch drum. The driven gear and the drive gear mesh. The driven gear is fixedly sleeved on the outer wall of the winch drum. A connecting plate and a fixing plate are fixedly connected to both sides of the lower end face of the base, respectively. A deflector plate is rotatably connected between the connecting plates. Brush bristles are fixedly connected to the outer walls of the deflector plate and the fixing plate on opposite sides. The wire rope passes through the brush bristles. By setting up the deflector plate, the fixing plate, and the brush bristle structure, the wire rope is effectively cleaned. This solves the problem that the wire rope, which is traditionally wound on the winch drum and exposed, easily accumulates dust and clumps on its surface with increasing use, affecting its performance. This invention is practical.

[0024] A vertical winch-type gate opener includes a winch 1, and the winch 1 has a wire rope winding mechanism 2 inside for orderly winding of the wire rope. The wire rope winding mechanism 2 includes:

[0025] The base unit 21 is disposed inside the winch 1 and includes a slide rail base plate 211. A guide groove 212 is provided on the front side of the slide rail base plate 211. A set of guide rails 213 are fixedly installed inside the slide rail base plate 211. A sliding guide seat 214 is slidably installed inside the guide rails 213. A linkage rod 215 is fixedly installed on one side of the sliding guide seat 214. A cable guide ring 216 is fixedly installed on one side of the linkage rod 215. The support rod of the cable guide ring 216 slides inside the guide groove 212. Reciprocating cable laying is achieved by the cable guide ring 216 sliding inside the guide groove 212.

[0026] A reciprocating drive unit 22 is disposed on the rear side of the base unit 21 and is used to drive the base unit 21.

[0027] In this embodiment, the reciprocating drive unit 22 includes a first sprocket 221 and a second sprocket 222 rotatably mounted on the inner side of the slide rail base plate 211. A reciprocating chain 223 is installed between the first sprocket 221 and the second sprocket 222. A servo motor 224 is fixedly mounted on the front side of the slide rail base plate 211. The output end of the servo motor 224 passes through the slide rail base plate 211 and is fixedly connected to the second sprocket 222.

[0028] The servo motor 224 is model OMV800. It is electrically connected to an external power supply and is operated by a human control panel. The servo motor 224 directly drives the second sprocket 222 to achieve synchronous matching between the moving speed of the cable guide ring 216 and the rotation speed of the drum 12.

[0029] In this embodiment, a fixed seat 225 is fixedly installed on the rear side of the reciprocating chain 223, and a linkage wheel 226 is rotatably installed on the rear side of the fixed seat 225.

[0033] In this embodiment, the winch 1 includes a frame 11, and a slide rail base plate 211 is fixedly installed inside the frame 11. A drum 12 is rotatably installed inside the frame 11 via bearings. A driven sprocket 13 is fixedly installed on the shaft of the drum 12. A linkage shaft 14 is rotatably installed inside the frame 11 via bearings. A linkage sprocket 15 is fixedly installed on the surface of the linkage shaft 14.

A first chain 19 is installed between the secondary drive sprocket 16 and the drive sprocket 18.

[0034] The drive motor 17 is a three-phase asynchronous motor with a self-locking function. It is electrically connected to an external power supply and can be opened and closed via a human-operated control panel. The steel cable of the drum 12 passes through the cable guide ring 216. The operation of the drive motor 17 drives the drive sprocket 18 to rotate. The drive sprocket 18 drives the secondary sprocket 16 to rotate via the first chain 19. The secondary sprocket 16 drives the linkage shaft 14 and the linkage sprocket 15 to rotate. The linkage sprocket 15 drives the driven sprocket 13 to rotate via the second chain 110. The driven sprocket 13 drives the drum 12 to rotate, and the drum 12 winds up the steel cable.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] During operation, firstly, the steel cable of the drum 12 passes through the cable guide ring 216. The drive motor 17 runs and drives the drive sprocket 18 to rotate. The drive sprocket 18 drives the secondary sprocket 16 to rotate through the first chain 19. The secondary sprocket 16 drives the linkage shaft 14 and the linkage sprocket 15 to rotate. The linkage sprocket 15 drives the driven sprocket 13 to rotate through the second chain 110 installed between them. The driven sprocket 13 drives the drum 12 to rotate, and the drum 12 winds up the steel cable.

[0037] Then, when the drum 12 winds up the steel cable, the servo motor 224 drives the second sprocket 222 to rotate. The second sprocket 222 drives the reciprocating chain 223 to rotate through the first sprocket 221. The reciprocating chain 223 drives the fixed seat 225 to rotate. The fixed seat 225 drives the linkage wheel 226 to slide inside the linkage slide rail 217. The linkage wheel 226 drives the cable guide ring 216 to slide back and forth inside the guide groove 212. The cable guide ring 216 drives the steel cable to move back and forth, and performs reciprocating motion to wind up the steel cable.
