Description

Technical Field

[0001] This utility model belongs to the field of winch technology, specifically relating to a winch that prevents rope damage. Background Technology

[0002] A winch is a small, lightweight lifting device that uses a drum to wind steel wire rope or chain to lift or pull heavy objects; it is also called a winch. Winches can lift vertically and pull heavy objects horizontally or at an angle. Winches are divided into three types: manual winches, electric winches, and hydraulic winches. Electric winches are the most common. They can be used independently or as components in lifting, road construction, and mine hoisting machinery. They are widely used due to their simple operation, large rope capacity, and ease of relocation. They are mainly used for lifting or dragging materials in construction, water conservancy projects, forestry, mining, and docks.

[0003] In the existing technology, when the winch is reversed during use, the wire rope is prone to getting tangled with the winch drum, which can easily lead to wire rope pinching and pulling. The rope strands may be cut or overstretched, causing the rope strands to loosen, break, or damage the internal structure, accelerating the wear and fatigue of the wire rope, thereby shortening its service life. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a winch designed to prevent wire rope damage, characterized by preventing wire rope deviation and ensuring precise positioning.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a winch for preventing rope damage, comprising a winch base, a drive motor installed on one side of the upper end of the winch base, a gearbox connected to the output end of the drive motor, a second vertical plate fixed to the upper end of the winch base corresponding to the output end of the gearbox, a take-up roller movably connected to one side of the second vertical plate, a first vertical plate movably connected to one end of the take-up roller, and a plurality of positioning anti-pinch components inserted between the first vertical plate and the second vertical plate.

[0006] Preferably, bearing seats are installed inside the first and second vertical plates corresponding to the take-up rollers.

[0007] Preferably, the positioning anti-pinch component includes an anti-slip sleeve, which is inserted into the inside of the first upright plate. The anti-slip sleeve has symmetrically opened limit grooves inside, and a positioning protrusion is movably connected inside the limit groove. A round steel rod is fixedly connected to one end of the positioning protrusion, and a limit spring is fixedly connected to the middle of the anti-slip sleeve corresponding to the round steel rod.

[0008] Preferably, the first and second upright plates have several insertion holes corresponding to the anti-slip sleeves inside, and both ends of the round steel insertion rod are equipped with anti-slip sleeves.

[0009] Preferably, the round steel insert and the positioning protrusion are an integral structure, and the surface of the positioning protrusion is flush with the anti-slip sleeve.

[0010] Preferably, the outer wall surface of the anti-slip sleeve is bonded with a damping pad, and the surface of the round steel insert is fitted with a wear-resistant sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention, by incorporating a positioning and anti-pinch component, allows for convenient positioning and installation of the round steel insert. Even when the winding roller reverses direction during use, the wire rope remains orderly wound around the surface of the winding roller. The surface of the round steel insert is also equipped with a wear-resistant sleeve, which reduces wear from the wire rope over long-term use. This prevents the wire rope from being cut or excessively stretched, thus reducing the risk of strand loosening, breakage, or internal structural damage when the wire rope is pinched or excessively stretched. This slows down wear and fatigue of the wire rope, thereby extending its service life. Attached Figure Description

[0017] By adopting the above technical solution, the normal rotation of the winding roller 3 is guaranteed, thus ensuring the stability of the wire rope winding.

[0018] Specifically, the positioning anti-pinch component 2 includes an anti-slip sleeve 22, which is inserted into the inside of the first upright plate 1. The anti-slip sleeve 22 has symmetrically opened limit grooves 23 inside. The limit grooves 23 are movably connected to the inside of the limit grooves 23. One end of the positioning protrusion 24 is fixedly connected to a round steel rod 25. The middle of the inside of the anti-slip sleeve 22 is fixedly connected to a limit spring 21 corresponding to the round steel rod 25.

[0019] By adopting the above technical solution, the anti-slip sleeve 22 is pressed to move along the positioning protrusion 24 and the limiting spring 21 is compressed. Then, the anti-slip sleeves 22 at both ends of the round steel rod 25 are installed in accordance with the insertion hole. At this time, the limiting spring 21 resets and pushes the anti-slip sleeve 22 to be inserted into it, ensuring the convenience and stability of the positioning and installation of the round steel rod 25.
