In the description of the present invention, it is to be understood that the terms "center", "front-back direction", "left-right direction", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", and the like indicate the directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and thus, should not be construed as limiting the present invention.

The following describes in detail a rope guide according to an embodiment of the present invention with reference to the accompanying drawings.

As shown in fig. 8 to 14, the rope guide 5 according to the embodiment of the present invention includes a slider 50, a rope guide drum 51, a rope guiding axle 52, a rope guiding axle 53, and an adjusting handle 54, and the slider 50 has a central cavity 500 penetrating in the front-rear direction. The front and rear surfaces of the slider 50 are opened so that the cable L can pass through the slider 50 in the front-rear direction.

The rope drum 51 includes an upper rope drum 511 and a lower rope drum 512. An upper cord guide 511 is rotatably disposed within the central chamber 500, a lower cord guide 512 is rotatably disposed within the central chamber 500, the lower cord guide 512 being opposite the upper cord guide 511 and spaced apart from each other. As shown in fig. 8 and 9, the upper rope guide 511 and the lower rope guide 512 are provided in the central chamber 500 with their central axes parallel to each other, and the upper rope guide 511 and the lower rope guide 512 are opposed to each other in the up-down direction and spaced apart from each other.

The rope sheave 53 is rotatably mounted on the rope sheave axle 52 and is located within the central cavity 500. Therefore, when the cable L is wound on the drum 2 of the winch (reeling in) or unwound from the drum 2 (unreeling), the cable L passes around the highest point of the rope aligning surface of the rope aligning roller 53 and passes through the gap between the upper and lower rope guiding drums 511 and 512, thereby guiding the cable L.

An adjustment handle 54 is connected to the roping axle 52 for adjusting the roping wheel 53 between a tensioned position for tensioning the cable L and a released position for releasing the cable L. In other words, the adjustment handle 54 is connected to the rope guiding axle 52, and by adjusting the adjustment handle 54, the rope guiding axle 52 can move the rope guiding wheel 53, so that the rope guiding wheel 53 moves between the tensioning position for tensioning the rope L and the releasing position for releasing the rope L. The cable L has a certain tension during the reeling in to ensure that the cable L is tightly arranged on the reel 2, whereby the winding sheave 52 is in a tensioned position when the free end L1 of the cable L is reeled in under load (unloaded reeling in) to ensure that the cable L is wound neatly on the reel 2.

According to the utility model discloses rope guider can conveniently adjust rope arranging wheel 53 through adjustment handle 54 to make rope arranging wheel 53 remove between tensioning mooring rope L's tensioning position and release mooring rope L's release position, thereby simple structure, with low costs, it is reliable to adjust.

In one example, the central axis of the lower cord reel 512 is aligned in the up-down direction with the central axis of the upper cord reel 511. In other words, as shown in fig. 9, the axial lengths of the lower rope guide 512 and the upper rope guide 511 are the same, and the left end surface of the lower rope guide 512 is aligned with the left end surface of the upper rope guide 511 in the up-down direction, and the right end surface of the lower rope guide 512 is aligned with the right end surface of the upper rope guide 511 in the up-down direction. The upper and lower rope drums 511 and 512 are spaced apart by a predetermined distance in the up-down direction, so that a gap through which the rope L passes is formed between the upper and lower rope drums 511 and 512.

In some embodiments, the cord aligning roller 53 and the cord guide drum 51 are offset from each other in the front-rear direction. Specifically, as shown in fig. 8, the rope aligning roller 53 is located behind the upper and lower rope drums 511 and 512.

It will be appreciated that the rope aligning wheel 53 is movable in the up-down direction, and the free end L1 of the rope L passes over the rope aligning wheel 53 around the rope aligning wheel 53 and passes between the upper rope guide 511 and the lower rope guide 512. When the rope discharging pulley 53 moves upward from the releasing position to the tensioning position, the distance between the rope discharging pulley 53 and the upper rope guide 511 in the up-down direction decreases, thereby tensioning the rope L.

In some embodiments, in the tensioned position, the highest point of the rope guiding surface of the rope guiding wheel 53 is higher than the lowest point of the rope guiding surface of the upper rope guiding drum 511, and in the released position, the highest point of the rope guiding surface of the rope guiding wheel 53 is lower than the highest point of the rope guiding surface of the lower rope guiding drum 512 or is substantially flush with the highest point of the rope guiding surface of the lower rope guiding drum 512.

The operation of the winch according to an embodiment of the present invention will be described with reference to fig. 15 to 18.

When the free end L1 of the cable L is unloaded and it is necessary to wind the cable L onto the winding drum 2 (unloaded winding), as shown in fig. 15, the engaging plate 433 of the clutch 43 engages with the spiral groove 420 of the transmission shaft 42 to make the sheath body 41 carry the slider 50 to move in the left-right direction under the driving of the transmission shaft 42. Both ends of the rope sheave 52 are located in the first recess 505 and the second recess 506, respectively, so that the rope sheave 53 is in a tensioned position, thereby tensioning the rope L. In other words, the portion of the cable L between the drum 2 and the lower rope drum 512 is curved.

The rope L passes over the rope sheave 53, passes around the rope sheave 53, and passes between the upper rope guide 511 and the lower rope guide 512. Since the highest point of the rope aligning surface of the rope aligning pulley 53 is higher than the lowest point of the rope aligning surface of the upper rope guide 511, the rope L is wound around the drum 2 in order with tension.

When the free end L1 of the cable L is unloaded and it is desired to unwind the cable L from the reel 2 (unloaded payout), as shown in fig. 16, the engaging plate 433 of the clutch 43 disengages from the spiral groove 420 of the drive shaft 42 so that the drive shaft 42 can no longer drive the slider 50 to move. Both ends of the rope discharging pulley 52 are respectively located in the lower ends of the first long groove 503 and the second long groove 504 so that the rope discharging pulley 53 is in the release position. The rope L passes around the rope discharging pulley 53 and passes between the upper rope guide 511 and the lower rope guide 512, and the highest point of the rope discharging surface of the rope discharging pulley 53 is lower than the highest point of the rope guiding surface of the lower rope guide 512 or is substantially flush with the highest point of the rope guiding surface of the lower rope guide 512.

When the free end L1 of the cable L is loaded and loaded greatly (exceeding the strength of the drive shaft 42), and it is necessary to wind the cable L onto the reel 2 (load winding), as shown in fig. 17, the engaging plate 433 of the clutch 43 is disengaged from the spiral groove 420 of the drive shaft 42, so that the drive shaft 42 can no longer drive the slider 50 to move, thereby protecting the safety of the drive shaft 42. Both ends of the rope discharging pulley 52 are located in the lower ends of the first long groove 503 and the second long groove 504 so that the rope discharging pulley 53 is in the release position. The rope L passes around the rope discharging pulley 53 and passes between the upper rope guide 511 and the lower rope guide 512, and the highest point of the rope discharging surface of the rope discharging pulley 53 is lower than the highest point of the rope guiding surface of the lower rope guide 512 or is substantially flush with the highest point of the rope guiding surface of the lower rope guide 512.

When the free end L1 of the cable L is loaded and loaded more (beyond the strength to which the drive shaft 42 is subjected), and the cable L is unwound from the reel 2 (load payout), as shown in fig. 18, the engaging plate 433 of the clutch 43 disengages from the spiral groove 420 of the drive shaft 42 so that the drive shaft 42 no longer drives the slider 50 to move. Both ends of the rope discharging pulley 52 are located in the lower ends of the first long groove 503 and the second long groove 504 so that the rope discharging pulley 53 is in the release position. The rope L passes around the rope discharging pulley 53 and passes between the upper rope guide 511 and the lower rope guide 512, and the highest point of the rope discharging surface of the rope discharging pulley 53 is lower than the highest point of the rope guiding surface of the lower rope guide 512 or is substantially flush with the highest point of the rope guiding surface of the lower rope guide 512.
