Description

Technical Field

[0001] The utility model belongs to the technical field of winches, and in particular relates to a wire rope guiding device for a winch. Background Art

[0002] The winch, also known as the winch, is a light and small lifting equipment that uses a drum to wind a wire rope or chain to lift or pull heavy objects. The winch consists of a power, a reduction mechanism, and a wire rope drum. It has the characteristics of simple structure, flexible use, and is not prone to failure. It is also the basic equipment of the crane. According to the different forms of the power device, the winch is divided into a manual winch, an electric winch, an internal combustion winch, a hydraulic winch, and a steam winch. According to the speed of the wire rope, there are fast winches, slow winches, and speed-adjustable winches. The working principle is to control the wire rope mainly through the rotation of the drum, thereby controlling the rise and fall of the heavy object. It can lift vertically, horizontally or tilt the heavy object, and 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 amount of rope winding, and convenient relocation. It is mainly used in the lifting or flat dragging of materials in construction, water conservancy projects, forestry, mines, docks, etc. The winch should be installed firmly and stably to prevent displacement and tilting when subjected to force.

[0003] Application No. 202222828502.6 provides a wire rope guide device for a winch, which is provided by installing a guide groove wheel on one side of the winch, and then limiting the wire rope or chain on the winch with the guide groove wheel, and finally lowering one end of the slide bar to make it tilted, so that during the operation of the winch, the guide groove wheel will slowly move the wire rope or chain to the lower point of the slide bar, so that the wire rope or chain can be arranged regularly and neatly on the winch drum;

[0004] However, the device tilts the slide bar so that the guide groove wheel slides on the surface of the slide bar. Since the winding process of the winch is relatively uniform, the sliding speed of the guide groove wheel on the surface of the slide bar is uneven due to the influence of friction, making it impossible for the guide groove wheel to cooperate with the winch to wind up evenly; and when the winch rewinds the second layer, the guide groove wheel needs to overcome gravity and friction to slide upward, resulting in poor winding uniformity of the winch and poor practicality.
