Information

Single drum winder is one of the main equipment in mine production. Its use directly affects the safety and output of mine production. In the past, Single drum winder mostly used wooden lining plates. Because they were not durable, the rope groove was quickly worn, resulting in rope running and rope biting, so they were replaced frequently. Some mines solve the problem of frequent replacement of rope lining by manufacture the steel drum lining with rope groove, but there are some disadvantages, such as too high cost and serious wear of steel wire rope.

According to the problems existing in the above two kinds of rope linings, after years of tackling key problems, our company has developed a new product - plastic lining plate ofSingle drum winder (hereinafter referred to as plastic lining)

Comparison of plastic lining with wood lining and steel lining

1.1 influence of rope lining material on steel wire rope

The wood lining itself has little wear on the steel wire rope, but due to its low strength and poor fatigue resistance, it is easy to crush and flatten the convex part of the rope groove by the steel wire rope, resulting in irregular arrangement of winding rope and rope biting, resulting in intensified wear of the steel wire rope and scrapping of broken wire exceeding the limit. Not only the direct cost is large, but also affects the safe operation of the hoist. Due to the large contact stress between the steel drum lining and the wire rope, the wear of the wire rope is more serious. The rope lining made of materials with low elastic modulus can significantly reduce the contact stress between the steel wire rope and the rope groove, greatly reduce the wear of the steel wire rope and effectively prolong the service life of the steel wire rope.

1.2 comparison of material selection, processing and installation

The lining wood of the drum of Single drum winder is strictly selected, usually oak , followed by high-quality Manchurian ash and hard miscellaneous wood. According to the technical requirements, it also needs to go through drying, blanking, oil immersion, grooving, installation , and the cycle is long. Due to the rough hand carved rope groove, poor dimensional accuracy and irregular rope arrangement, rope biting is very easy to occur, especially for the winch with multi-layer winding, rope disorder and rope biting are more likely to occur. The rope groove made by the mechanical rope groove device is of good quality, but the process is cumbersome, so the shutdown time is long (generally 2-5 days)

The steel drum lining with rope groove is actually equivalent to replacing two new drums. The installation workload is large, which generally takes at least 5 days.

The plastic lining plate is formed by pressing, and its thickness can be selected within a certain range. The rope groove is smooth and flat, and the steel wire rope is arranged neatly, which is particularly beneficial to multi-layer winding. Its installation method is simple and easy to operate.

1.2 comparison of cost and service life

Take 2JK-3 / 20 Double drum winder ( drum diameter:2000m, length:3000Mm) as an example: wood lining is adopted and 15 m³ round log is purchased ,1350 yuan / m³.According to the calculation, it is USD3068. The cost of storage, transportation and processing after purchase is about USD1820, and the total cost is USD 4888. The mine with an annual output of 80T can generally be used for about 1 year; The steel rope groove drum is adopted, the cost is about USD46000, and the service life is generally 20-25 years. With plastic lining, the cost is USD9400 yuan and the service life is generally 8-10 years. It can be seen that the comprehensive advantages of plastic lining in terms of price and use of longevity noodles are obvious.
