鋼絲繩使用和報廢標準

鋼絲繩使用和報廢標準
  一、鋼線繩應用考慮應當   (一)采用前定期檢查方式   絲繩繩的磨損情況、銹跡、拉伸運動、可以彎曲的、磨損、勞累、斷絲、絲繩繩繩芯展露的的程度。   (二)清洗保養注意力事情   1. 不銹不銹鋼絲的的適用時間期限與的適用的方式有不小影響,故此應練好按規范的適用,禁用拖拉、拋擲,的適用中不對時超功率,不對時使不銹不銹鋼絲遭受銳角折曲,不對時激增改善生降訪問速度,防止出現沖洗荷載。   2. 鋼纜繩有鐵銹和灰垢時,用鋼纜刷刷去并涂油。   3. 鋼板繩每用4個月時間涂油有一次,涂油時做好用熱油(50℃控制)浸濕繩芯,再擦去多余的的潤滑油。   4. 不銹鍍鋅鋼絲繩盤好后應擺在潔面潮濕的去處,不應偏移堆置,處理腰扭傷。   5. 鋼纜繩兩端用鋼纜扎好或用融點低的合金鋼焊牢,也可作鐵箍箍緊,立即繩頭渙散。   6. 運用中,鋼條繩外面此事油滴抽出,代表鋼條繩已所能承受一樣大的能量,這個時候應中斷增大負荷什么意思,并舉行進行檢查,必需時換成新鋼條繩。   7. 在使用的環節中,應注意力放置接下來事情產生:   (1)不銹索道鋼絲繩與電氣焊線觸碰。   (2)綱絲繩間間接接觸性。   (3)鍍鋅鋼絲繩繩與金屬件有凸起棱邊三天兩頭磨蹭。   (4)鋼條繩從早就破損掉鍍的滑輪上越過。   (5)吊裝作業弧度超60o。   (6)在室溫生活用品上實用的材料繩,必需使用保溫舉措,謹防較低強度和壽命短。   (7)綱絲繩車輛報廢截斷時,需要有解決繩股炸開的的具體措施。     二、鋼線繩報廢不能使用標準單位   絲繩繩出顯下例原因中之一,還應以折舊:   1. 關于交繞的材料繩在有是一個捻距(指相同有是一個材料繩股超重低音半個月的軸徑距離感)內的斷絲數達該繩總絲數的10%。   2. 吊運熾烈鋁合金或有危險品運輸的鋼板繩,其換新斷絲數取尋常起重機設備機的二分之一以上,如斷絲現像聚焦進行于輪廓,或在六倍于鋼板繩外徑時長內斷絲聚焦進行在一般上,應按第22項里面標準的二分之一以上既能換新。   3. 鋼板繩界面層鋼板腐燭或磨花達界面原絲徑的40%。   4. 鐵絲繩有突出的組織結構腐化。   5. 不銹鋼鍍鋅鋼絲繩直徑約減一少部分達7%。   6. 鐵絲繩與鋁和金線接頭部位零件零件有波浪紋或滑移變彎;插編鐵絲主繩具插編部位零件零件有特別嚴重抽脫;澆鑄鐵絲繩錨具與鐵絲繩進行接頭處某位移,遭受抽脫狀況。   7. 鋼條繩面上有受損或被氧化,又全是定數量的斷絲,斷絲數應在第2項或第2項的暫行規定上品以折減公式后區分:當受損或被氧化率主要在10%、15%、20%、30%-40%時,折減公式相關聯85%、75%、70%、60%、50%。   8. 整股斷或損壞。   9. 部分區域表層鋼繩繩受力呈“籠”形或鋼繩繩纖維板芯的厚度變高較造成。   10. 鐵絲繩發生扭結、方位、硬彎、延性出現易變型、麻芯滑脫等造成出現易變型。   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.
