Winch cable wiper assembly
A winch is described comprising a rotatable drum for winding and unwinding a first cable therefrom. The winch contains a cable-wiping apparatus with one or more actuators are activated when the drum rotates in a direction for winding the first cable onto the drum. A mechanical force may be transmitted from the actuator to a second cable that is operatively connected to a wiper clamp. The wiper clamp compresses around the first cable when the cable is pulled in.
1. A winch, comprising:
a rotatable drum for winding and unwinding a first cable therefrom;
a cable guide for positioning said cable onto the drum;
the cable guide comprising a cable-wiping apparatus;
the cable-wiping apparatus comprising:
one or more actuators powered by an electricity source that also powers rotational movement of the drum, and wherein the one or more actuators are activated only when the drum rotates in a direction for winding the cable onto the drum;
a second cable for transmitting a mechanical force comprising an inner cable positioned within an outer cable housing and operatively connected to at least one actuator;
a wiper clamp operatively connected to the second cable and positioned near the first cable;
wherein the wiper clamp comprises at least one jaw surface that is in contact with the first cable when the first cable is pulled in.
2. The winch of claim 1 , wherein the electricity source is a lithium-ion battery.
3. The winch of claim 2 , wherein the lithium-ion battery is small cylindrical, large cylindrical, pouch, or prismatic in shape.
4. The winch of claim 2 , wherein the lithium-ion battery is rechargeable.
5. The winch of claim 1 , wherein the shape of the jaw surface is concave, planar, porous, and/or include one or more depressions.
6. The winch of claim 1 , wherein the jaw surface is comprised of rubber, plastic, polypropylene, polyvinyl chloride, acrylonitrile butadiene styrene, polyurethane, or latex.
7. The winch of claim 1 , wherein the cable-wiping apparatus comprises a side-pull clamping mechanism.
8. The winch of claim 1 further comprising a tension motor for rotating the drum.
9. The winch of claim 8 , wherein the tension motor is operatively connected to the same power source as the actuator.
10. The winch of claim 1 , wherein the second cable is a flexible metal cable comprising a composite outer cable housing, a longitudinal incompressible layer.
11. A winch, comprising:
a rotatable drum for winding and unwinding a first cable therefrom;
a first electricity source operatively connected to a tension motor located within the drum;
a cable guide for positioning said cable onto the drum;
the cable guide comprising a cable-wiping apparatus;
the cable-wiping apparatus comprising:
one or more actuators powered by a second electricity source located internal to the winch;
wherein the one or more actuators are activated only when the drum rotates in a direction for winding the cable onto the drum;
a second cable for transmitting a mechanical force comprising an inner cable positioned within an outer cable housing and operatively connected to at least one actuator;
a wiper clamp operatively connected to the second cable and positioned near the first cable;
wherein the wiper clamp comprises at least one jaw surface that is in contact with the first cable when the first cable is pulled in.
12. The winch of claim 11 , wherein the second electricity source is a lithium-ion battery.
13. The winch of claim 12 , wherein the lithium-ion battery is small cylindrical, large cylindrical, pouch, or prismatic in shape.
14. The winch of claim 12 , wherein the lithium-ion battery is rechargeable.
15. The winch of claim 12 , wherein the lithium-ion battery is located within a frame that supports the drum.
16. The winch of claim 11 , wherein the first electricity source is located external to the winch.
17. The winch of claim 11 , wherein the cable-wiping apparatus comprises a side-pull clamping mechanism.
18. The winch of claim 11 , wherein the shape of the jaw surface is concave, planar, porous, and/or include one or more depressions.
19. The winch of claim 11 , wherein the jaw surface is comprised of rubber, plastic, polypropylene, polyvinyl chloride, acrylonitrile butadiene styrene, polyurethane, or latex.
20. The winch of claim 11 , wherein the second cable is a flexible metal cable comprising a composite outer cable housing, a longitudinal incompressible layer.
