鋼絲繩使用和報廢標準
  一、絲繩繩采用準備事情   (一)選用前檢驗方式   不銹鋼鋼纜的磨損情況、脫漆、延展、變行、變行、疲倦、斷絲、不銹鋼鋼纜繩芯顯示的因素。   (二)養護要留意裝修細節   1. 綱絲繩的實用執行期與實用做法有相當大關聯,故而應達到按設定實用,不許拖拉、拋擲,實用中禁止超工況,禁止使綱絲繩發生了銳角折曲,禁止急驟優化上下的速度,制止震蕩承載力。   2. 剛絲繩有鐵銹和灰垢時,用剛絲刷刷去并涂油。   3. 鋼條繩每施用4六個月涂油以此,涂油時最容易用熱油(50℃兩邊)浸濕繩芯,再擦去多此一舉的食用油。   4. 不銹鋼繩盤好后應擺在清潔衛生低溫干燥的地兒,不宜重合堆置,可以防止腰扭傷。   5. 鐵絲繩受拉區用鐵絲系緊或用溶點低的碳素鋼焊牢,也也可以鐵箍箍緊,否則繩頭干硬。   6. 施用中,綱絲繩表明若有油滴擠壓,標識綱絲繩已必須很大的魔力,這個時候應結束增強強度,齊頭并進行常規檢查,有必要的時更新新綱絲繩。   7. 在用方式中,應注重以防以內前提導致:   (1)絲繩繩與電氣焊線接觸的面積。   (2)鋼板繩間同時了解。   (3)絲繩繩與輕金屬急劇割痕一直靜摩擦。   (4)鋼條繩從都已經開裂的滑輪上走過。   (5)起吊偏角已超60o。   (6)在高溫裝飾物上便用的鋼條繩,需運用隔冷方法,避免削減承載力和期。   (7)鋼纜繩車輛報廢斷掉時,應用杜絕繩股炸開的預防措施。     二、不銹鋼鋼纜報廢不能使用準則   不銹鋼吊車鋼絲繩誕生下列不屬于具體情況的一種,還應以拆卸:   1. 相對 交繞的材料繩在1個捻距(指任意尺寸1個材料繩股3d環繞十天的軸徑空距)內的斷絲數達該繩總絲數的10%。   2. 吊運熾烈彩石或安全風險品的鐵絲繩,其報費斷絲數取似的起重設備機的一邊,如斷絲的問題集結有于不規則,或在六倍于鐵絲繩內徑總長度內斷絲集結有在1股上,應按第5項中歸定的一邊可以報費。   3. 不銹鋼鐵絲外層層不銹鋼鐵絲灼傷或磨損情況達外層原絲徑的40%。   4. 不銹鋼鍍鋅鋼絲繩有很大的里面金屬腐蝕。   5. 綱絲繩直徑為減一些達7%。   6. 剛絲繩與鋁合金型材類接線頭布位有裂痕或滑移彎曲;插編剛絲繩鎖具插編布位有難治抽脫;澆鑄剛絲繩錨具與剛絲繩銜接處這位移,形成抽脫表現。   7. 鋼條繩表面上有偏磨或腐燭,又一定數量的斷絲,斷絲數應在第四項或第2項的標準規定優良以折減指數后認定:當偏磨或腐燭率各自在10%、15%、20%、30%-40%時,折減指數使用85%、75%、70%、60%、50%。   8. 整股損傷或短路。   9. 高斯模糊表面層剛絲繩張拉呈“籠”形或剛絲繩化學纖維芯的直徑不低于變高較明顯。   10. 不銹鋼主繩發現扭結、?盲區、硬彎、塑形發生形變、麻芯脫落等較為嚴重的發生形變。   1. Matters needing attention in the use of wire rope (1) Check the content before use The degree of wear, corrosion, stretching, bending, deformation, fatigue, broken wire, and exposure of the core of the wire rope. (2) Maintenance precautions 1. The service life of the wire rope has a lot to do with the method of use. Therefore, it should be used according to the regulations, dragging and throwing are prohibited, overloading is not allowed during use, the wire rope is not allowed to bend at an acute angle, and the lifting speed is not allowed to change sharply. Avoid shock loads. 2. When the wire rope has rust and dust, use a wire brush to remove it and apply oil. 3. The steel wire rope should be oiled every 4 months. It is best to soak the rope core with hot oil (about 50℃) and wipe off the excess grease. 4. After the wire rope is wound, it should be placed in a clean and dry place, and should not be stacked to prevent sprain. 5. The end of the wire rope should be fastened with steel wire or welded with alloy with low melting point, or can be fastened with iron hoops to avoid loosening of the rope head. 6. ??During use, if oil droplets are squeezed out on the surface of the wire rope, it means that the wire rope has been subjected to considerable strength. At this time, the load should be stopped and the inspection should be carried out. If necessary, replace with a new wire rope. 7. During use, care should be taken to prevent the following situations from appearing: (1) The wire rope is in contact with the welding wire. (2) Direct contact between steel wire ropes. (3) Steel wire rope and metal sharp edges and corners are often rubbed. (4) The wire rope is passed through the broken pulley. (5) The hoisting angle exceeds 60o. (6) The steel wire rope used on high temperature objects must be insulated to prevent the strength and lifespan from being reduced. (7) When the wire rope is scrapped and cut, there should be measures to prevent the strands from spreading. 2. Steel wire rope scrap standard The wire rope should be scrapped if one of the following occurs: 1. The number of broken wires in a lay length (referring to the axial distance of any wire rope strand around a circle) for the entangled wire rope reaches 10% of the total wire number of the rope. 2. For steel wire ropes that are used for lifting hot metal or dangerous goods, the number of scrapped and broken wires is half of that of ordinary cranes. If wire breakage occurs locally, or within six times the diameter of the wire rope, it should be Half of the stipulated in item 1 can be scrapped. 3. The corrosion or abrasion of the steel wire on the surface of the wire rope reaches 40% of the original wire diameter. 4. The steel wire rope has obvious internal corrosion. 5. The wire rope diameter is reduced by 7%. 6. ??There are cracks or slipping deformation at the joint between the steel wire rope and the aluminum alloy; the insertion part of the inserted braided steel wire rope is severely pulled off; the cast wire rope anchorage and the wire rope have displacement at the connection point, and the phenomenon of pulling off occurs. 7. The surface of the steel wire rope is worn or corroded, and there are a certain number of broken wires. The number of broken wires should be determined by multiplying the provisions of item 1 or item 2 by the reduction factor: when the wear or corrosion rate is 10%, 15 %, 20%, 30%-40%, the reduction factor corresponds to 85%, 75%, 70%, 60%, 50%. 8. The whole strand is broken or burned out. 9. The local outer steel wire rope elongates in a "cage" shape or the diameter of the steel wire rope fiber core increases severely. 10. The wire rope is seriously deformed such as kinks, dead ends, hard bends, plastic deformation, and hemp core out.
