The Wire

In order to improve the service life of wire rope used n tensile stringing, an automatic cleaning, detection and maintenance integration system was designed. Through the simulation analysis of elastic plates that fix the fixed brushes and the design of the rotating brushes driving system, a wire rope decontamination device assembled fixed brushes and rotating brushes was developed according to the demand of steel wire decontamination. The brush head adopts the design concept of elastic device, which makes the wire rope pressing force adjustable, ensures the wire connectors passable and makes the axial dirt sweeping of different diameter wire rope possible. The overall rotation mechanism with multiple brushes can circumferentially sweep the dirt in the wire rope gap. Then, the wire ropes were comprehensively sweeped with no dead cleanup. The device has been actually used, and the results showed that the decontamination effect is good.

Electromagnetic testing is the most widely used technique for the inspection of steel wire ropes. As one of the electromagnetic detecting approaches, the magnetic flux leakage (MFL) method has the best effect for the detection of broken wires. However, existing sensors based on MFL method still have some problems. (1) The size of the permanent magnet exciter is usually designed according to experience or rough calculation, and there is not enough depth analysis for its excitation performance; (2) Since the detectable angular range for a single Hall component is limited, Hall sensor arrays are often employed in the design of MFL sensors, which will increase the complexity of the subsequent signal processing due to the extensive use of Hall components; (3) Although the new magneto-resistance sensor has higher sensitivity, it is difficult to be applied in practice because of the requirement of the micron-level lift-off. To solve these problems, a sensor for the detection of broken wires of steel wire ropes based on the principle of magnetic concentration is developed. A circumferential multi-circuit permanent magnet exciter (CMPME) is employed to magnetize the wire rope to saturation. The traditional Hall sensor array is replaced by a magnetic concentrator to collect MFL. The structural parameters of the CMPME are optimized and the performance of the magnetic concentrator is analyzed by the finite element method. Finally, the effectiveness of the designed sensor is verified by wire breaking experiment. 1–5 external broken wires, handcrafted on the wire rope with a diameter of 24 mm, can be clearly identified, which shows great potential for the inspection of steel wire ropes.

The Wire

Anchor chocks are used in the sport of rock climbing for providing secure attachment to a rock face. They are used at regular intervals and must be light weight (since many are carried) and also sufficiently strong to withstand an impact force should a climber fall from a height. In chock design, steel wire cable is widely used for connecting the nut component, which is wedged into a rock crevice, to the free end which attaches, via a karabiner link, to the safety rope. However, the wire cable is vulnerable to failure as it can fray with use at exposed ends - especially when folded into a loop using tight bends. Also, the ferrule end connections are considered a potential design weakness. In a research programme tests have been carried out on new and also some well used anchor chocks and has revealed very different, and some unpredicted, failure modes – depending on the state of the wire rope and whether the applied load at failure was static or impact. This paper presents the results of test failures for a range of chocks and discusses the benefits of using single lengths of wire cable with suitably swaged end ferrules.

This article introduces unbalance phenomenon when several steel wire ropes hoist skip and some main methods of measuring steel wire ropes tension in coal mine. Use the strain effects to design a sensor which can be used to measure the tension of steel wire rope, to provide reliable data for the subsequent online tension inspection system. In order to facilitate the sensor in this system, the height of the sensor needs to be low enough. As one of the most important parts of the strain sensor, the elastic body is also low-height. To solve that problem, first using the SolidWorks software modeling and analysis of elastic body to design the sizes and obtain the best patch position of strain gauge.

The Impact

The paper considers the causes of increased vibration of four auxiliary diesel-generator sets of "Sulzer" 5АL25 type on board nine refrigerated vessels of B437 / 11 project after 15 years of operation. The proposed wide range of possible applications to address the problem of high vibration of diesel generators and motor vessels there were generally implemented upgraded turbocharger brackets, engine sub-frame and supporting spiral-rope vibration isolators in the shock absorption system of the diesel-generator. Four original patented technical solutions have been presented, among which one solution is implemented in 5AL25 diesel generator and 2H 8.5/11 diesel damping systems. There has been offered wide application both wire rope vibration isolators and combined isolators, in which elastic elements are made of nonflammable materials. Wire rope vibration isolators combine high bearing capacity (static loads within 1 N - 50 kN) with high elasticity under dynamic effects; their natural frequencies can drop to 2.5 Hz. Under the worst conditions 75% of the free moving weakens the impact to values that ensure the necessary safety of the object. Experience in designing vibration isolation systems allows to set the maximum range of loads within 15 - 25 g. The vibration isolators made of steel wire rope are practically not affected by the environment, they are made of stainless steel. They effectively operate at temperatures -200°C - +370°C in the presence of oil, dirt, sand, salt fog, etc. They usually have a service life comparable with the service life of the insulated object. Wire rope vibration isolators and combined vibration isolators can be used in all fields of modern technology: shipbuilding, power engineering, automotive, aviation and space industries, etc.

A rope is an important, highly effective and one of the oldest transportation systems used in transport by mankind. Nowadays, steel ropes are mainly used for moving loads in mining - coal and ore exploitation, vertical or horizontal transport of persons and goods by cranes, elevators, lifts and cable ways. In many cases steel wire ropes are employed in extreme conditions with respect to the load of the rope: high temperature plants, mining corrosive environments and etc. In terms of labor safety it is necessary to certify each rope people come in contact when working with loads or a rope is used for transportation. It has to be done earlier than a rope is put into operation or on the market. Despite the fact the tests were performed correctly, a rope may not achieve the desired rope life. The great impact on the life of a wire rope has its interaction with a device a rope is deployed on. Interaction of a steel wire rope with a device it is deployed on has a great impact on its life. Durability is also affected by the way a rope is loaded, its maintenance and regular re-examination as well as its construction. Design accuracy is assessed according to strength and deformation properties of wires a rope is made of and a rope cross-section construction is taken in account as well. The important aspect of steel wire rope durability (which can be mostly influenced by a manufacturer) is an appropriate design of diameters and angles of wires winding in accordance with exactly defined conditions of operation. The paper presents models of ropes equally loaded which eliminates the most unfavorable factors affecting their life cycle.
