Freight winch structure with good use function

Abstract

The invention belongs to the technical field of winches, and discloses a freight winch structure with a good use function. The freight winch structure comprises a machine shell, a driving device is fixedly arranged at the rear end of the machine shell, a first duplicate gear is movably connected to the front end of the right end of the machine shell, a traction assembly is fixedly arranged at the left end of the first duplicate gear, and the bottom of the front end of the machine shell is movably connected with a double-thread ball screw. According to the freight winch structure, a forward rotation gear drives the double-thread ball screw to rotate, an air cylinder drives a selection gear to move rightwards, the selection gear is separated from the forward rotation gear and meshed with a second duplicate gear, therefore periodic reverse rotation of the double-thread ball screw is achieved, and the double-thread ball screw can drive two meshing blocks to periodically reciprocate left and right, so that traction ropes can be uniformly arranged on the surface of a winding pipe, the winding positions and the winding displacement directions of the two groups of traction ropes are ensured to be completely the same, and the traction and dragging stability of a device is ensured.

Description

technical field [0001] The invention belongs to the technical field of winches, in particular to a cargo winch structure with good usability. Background technique [0002] The electric traction winch is mainly used to tow cargo such as containers, vehicles and large equipment into the interior of the helicopter cargo compartment. When the aircraft cannot provide effective power supply or its own electrical components fail, it can switch to manual mode to perform the cargo traction function, mainly driven by an external motor. , controllers, sensors and cables. [0003] When the existing winch is in use, the rotation of the winch drives the traction rope to be released from the winch and wound up on the winch, so as to realize the release and drag of the goods, but when the goods are pulled, Most of the cargo is connected to both ends of the traction rope to ensure the stability of the cargo when dragging.

AI Technical Summary

Problems solved by technology

[0003] When the existing winch is in use, the rotation of the winch drives the traction rope to be released from the winch and wound up on the winch, so as to realize the release and drag of the goods, but when the goods are pulled, Most of the cargo is connected to both ends of the traction rope to ensure the stability of the cargo when dragging. However, when the two sets of traction ropes are rewound, the winding position and direction of the two sets of traction ropes on the reel may appear. Deviations may cause one end of the cargo to move a certain distance instantaneously when dragging the cargo, which may cause interference between the cargo being towed and the side wall of the cabin, resulting in damage to the cargo and the cabin, and reducing the efficiency of towing and dragging. stability

[0004] When the existing winches are rewinding and unwinding the traction rope, most of them directly drive the hoist drum to rotate through the driving device to realize rewinding and unwinding, but when the device suddenly loses power supply, although the manual device can be used to continue to complete the rewinding However, at the moment of sudden power failure, the cargo may slide backwards due to the loss of traction power, and may touch the walking personnel when sliding out of the cabin, resulting in injury to personnel, thus reducing the safety of the device. safety

[0005] When the existing winch is rewinding and unwinding the traction rope, although the driving device can control the winding speed of the traction rope, it may still occur that the traction rope is not tightly wound on the winch during winding. situation, resulting in slack in the traction rope. When it is released, the traction rope at the slack part may slip out of one end in an instant, resulting in different stretching lengths of the two sets of traction ropes, which cannot pull the goods smoothly, thereby reducing the The scope of use of the device
