AI Technical Summary
The existing winches using double-drum winches do not have a limit device during the rope unwinding process, resulting in uneven distribution of the wire rope, which is prone to tangling and wear.
A double-cylinder winch with a wire rope protection mechanism was designed, including a support frame, motor, pulley set, reciprocating screw, sliding sleeve, threaded rod, limit block and other components. The motor drives the pulley set to rotate the reciprocating screw, and the sliding sleeve moves to limit the wire rope, ensuring that the wire rope is wound in the same direction, reducing wear, and the snap-fit structure facilitates disassembly and maintenance.
This allows the wire rope to be wound evenly on the drum, reducing wear and facilitating drum disassembly and maintenance.

Description
Technical Field
[0001] The utility model relates to the technical field of double-cylinder reels for winches, in particular to a double-cylinder reel for winches with a wire protection mechanism. Background Art
[0002] A winch is a small and light lifting equipment that uses a drum to wind a wire rope or chain to lift or pull heavy objects. It is also called a winch. The winch can lift vertically, pull heavy objects horizontally or tilted. There are three types of winches: manual winches, electric winches and hydraulic winches. Electric winches are the main ones. It can be used alone or as a component of machinery such as lifting, road construction and mine hoisting. It is widely used because of its simple operation, large rope winding capacity and convenient relocation. It is mainly used for lifting or flat towing materials in construction, water conservancy projects, forestry, mines, docks, etc., but the existing winches use double-cylinder drums, which have some shortcomings, such as:
[0003] Publication No.: CN208932858U A winch of a dragline excavator uses a built-in double-cylinder drum, and a matching drum tile is set, which is equivalent to setting a second winding drum. The inner drum is used to wind the reserved wire rope, and the drum tile is used to wind the wire rope used this time. When the head end of the wire rope is worn and needs to be replaced, it is not necessary to replace the entire wire rope, but only the worn part of the head end needs to be replaced, which saves the use of wire rope, reduces unnecessary waste, and saves costs. However, the device has certain defects;
[0004] This device does not have a limit device during the rope release process, which results in uneven distribution of the wire ropes during rope winding and easy entanglement, causing friction between the wire ropes and a certain amount of wear.
[0005] Therefore, we propose a double-cylinder drum for a winch with a wire protection mechanism to solve the above-mentioned problems. Utility Model Content

[0033] A connecting block 15 is welded to one side of the reel body 14 , and a fixing block 16 is welded to one side of the support frame 1 . The reel body 14 and the support frame 1 are connected via the connecting block 15 and the fixing block 16 .
