Many people do not know much about the connection device of Mining Hoist Winch. Let me introduce the inspection and maintenance of the winch connection device for you.
There are three types of Mining Hoist Winch connection devices: clip-type hook head, plug-in hook head, and sliding head hook head.
The clip-type hook head is composed of a U-shaped rope clamp, a rope guard ring and a single-loop chain (or a double-loop chain or a triple-loop chain), which is often used for lifting of small winches. Its structure is simple, it is easy to make, it is convenient to change parts, and it is used more. However, the u-shaped clip nut is easy to loosen and fall off, and a sports car accident may occur. You must check the Mining Hoist Winch tightening once every shift, and ensure that each hook head has no less than 4 pairs of clips and rope guards intact.
The plug-in hook head uses the frictional force between the strands after the Mining Hoist Winch is inserted to bear the lifting load, and is also composed of a rope guard ring, a chain and a plug-in buckle. Its safety is good, it is easy to make, and it has many uses. However, the quality of the plug must be guaranteed. The length of the plug should be no less than 4 to 5 twist lengths, and the rope guard ring should be intact and not fall off. Each shift should be inspected for broken wires, abrasion, corrosion and deformation.
The sliding head type hook head is a connection device which injects the loosening rope head with hooks of Mining Hoist Winch into the body of the sliding head with tungsten gold, and is often used for the lifting of the main inclined shaft. Its safety is good, the life of the winch operator is long, but the production process is more complicated, so the small winch is less used, and it is mostly used for the surface wellhead lifting of the main inclined shaft. Hook head tungsten gold infusion process quality must be strictly guaranteed, otherwise the wire rope head pullout accident will occur. The key to ensuring quality is to strictly degrease the inner wall of the slider and the wire of the rope head, and to reliably coat the surface with a tin layer, so as to ensure that the tungsten alloy is closely connected to the inner wall of the slider and the wire head after the pouring of tungsten, preventing the occurrence of the extraction .
