【摘要】：在當(dāng)前社會(huì)中隨著經(jīng)濟(jì)的快速發(fā)展,鋼絲繩在實(shí)際生活生產(chǎn)中的應(yīng)用越來越多,如港口、起重提升、煤礦、電梯等中都得到了廣泛的使用。但是隨著鋼絲繩在生活生產(chǎn)中的長(zhǎng)期使用,其不免會(huì)發(fā)生銹蝕、磨損、斷絲等損傷,如果不及時(shí)發(fā)現(xiàn)并處理這些問題,那么就必將造成生產(chǎn)損失和人員安全威脅,因此鋼絲繩是否能安全使用就成為人們關(guān)注的重點(diǎn)。因?yàn)槠涫褂玫陌踩灾苯雨P(guān)乎到人員的生命以及正常的工作能否順利完成。要判定安全性就需要對(duì)其進(jìn)行檢測(cè),不同的檢測(cè)方法有不同的精度,因此,需要進(jìn)一步探究其檢測(cè)方法。鋼絲繩損傷檢測(cè)的結(jié)果可為準(zhǔn)確評(píng)價(jià)鋼絲繩目前的使用狀態(tài)以及其剩余使用時(shí)間提供科學(xué)依據(jù),以確保鋼絲繩在生產(chǎn)生活中安全、穩(wěn)定、長(zhǎng)期的使用。本論文首先對(duì)鋼絲繩的結(jié)構(gòu)和各種損傷情況及其特點(diǎn)進(jìn)行分析,其損傷檢測(cè)主要針對(duì)鋼絲繩在使用過程中常見的兩種損傷類型:一種是金屬截面積損傷類型,另一種是局部損傷類型。重點(diǎn)研究這兩種損傷類型的定性、定量檢測(cè),通過對(duì)檢測(cè)得到的漏磁信號(hào)進(jìn)行預(yù)處理和定量計(jì)算,進(jìn)而建立漏磁場(chǎng)信號(hào)與其損傷量值之間的關(guān)系,從而實(shí)現(xiàn)對(duì)其損傷判定。其次,利用基于集成霍爾元件的鋼絲繩損傷檢測(cè)系統(tǒng)所獲得的鋼絲繩損傷狀況信息,判別鋼絲繩的目前使用狀態(tài),為鋼絲繩的安全使用評(píng)定提供有效的依據(jù)。同時(shí),依據(jù)對(duì)鋼絲繩的使用安全規(guī)程和報(bào)廢標(biāo)準(zhǔn)開發(fā)鋼絲繩使用狀態(tài)評(píng)定系統(tǒng),實(shí)現(xiàn)鋼絲繩損傷的定量識(shí)別,并對(duì)其剩余使用時(shí)間做出估算。最后總結(jié)了研究過程中所取得的成果和顯露出的不足,提出接下來對(duì)鋼絲繩檢測(cè)技術(shù)研究的基本構(gòu)想,即針對(duì)實(shí)現(xiàn)鋼絲繩多種損傷類型同時(shí)進(jìn)行檢測(cè)的方法。
[Abstract]:In the current society, with the rapid development of economy, the application of wire rope in real life production is more and more, such as port, lifting, coal mine, Elevators have been widely used. But with the long term use of wire ropes in daily life, corrosion, wear, wire breakage and other damage will inevitably occur. If these problems are not detected and dealt with in time, Then it will inevitably cause production losses and threats to the safety of personnel. Therefore, whether the wire rope can be used safely has become the focus of attention, because the safety of the wire rope is directly related to the life of the personnel and the smooth completion of the normal work. To determine the safety, it is necessary to test it. Different detection methods have different accuracy, therefore, it is necessary to further explore the detection methods. The results of damage detection of steel wire rope can provide scientific basis for accurate evaluation of the current status of wire rope and its remaining service time. In order to ensure the safety, stability and long-term use of the wire rope in production and life, this paper first analyzes the structure, various damage conditions and their characteristics of the wire rope. The damage detection is mainly aimed at two kinds of damage types: one is the metal cross section damage type, the other is the local damage type. Through preprocessing and quantitative calculation of magnetic flux leakage signal, the relationship between magnetic leakage signal and its damage value is established, and the damage judgement is realized. By using the damage information of wire rope obtained by the damage detection system of steel wire rope based on integrated Hall element, the current usage status of wire rope is judged, which provides an effective basis for the safety evaluation of wire rope. According to the safety rules for the use of steel wire rope and the scrap standard, a system for evaluating the use status of steel wire rope is developed to realize the quantitative identification of wire rope damage. Finally, the paper summarizes the achievements and shortcomings of the research, and puts forward the basic idea of the research of the steel wire rope detection technology. That is, the method of simultaneously detecting various damage types of wire rope at the same time.
