Method for treating subway monolithic track bed sleeper dead bolt by applying electric heat conduction
The invention discloses a method for treating a dead bolt of a subway monolithic track bed sleeper by applying electric heat conduction, and relates to the technical field of subway track maintenance, and the method comprises the following steps: Step 1, cleaning the surface and the peripheral area of the dead bolt by using a brush; 2, whether a metal rod is additionally installed or not is determined according to the length of the dead bolt left in the nylon sleeve, and if the dead bolt is a broken bolt, a metal rod piece is additionally installed; otherwise, executing the step 3; 3, the dead bolt is heated through the hot melting welding technology, then a molten pool and welding slag are polished, and standing is conducted for more than ten seconds to several minutes; and step 4, circulating the step 3 for a plurality of times. According to the invention, the dead bolt is heated by high temperature generated by hot melting welding, so that the nylon sleeve is gradually softened, the dead bolt clamped in the large base plate is loosened, the dead bolt is disassembled, the track maintenance operation time is shortened, the work intensity is reduced, the track maintenance operation efficiency is improved, and the track maintenance operation cost is reduced.
本发明公开了一种应用电导热处理地铁整体道床轨枕死螺栓的方法，涉及地铁轨道维修技术领域，Step1：使用毛刷将死螺栓表面以及四周区域清扫干净；Step2：根据死螺栓留在尼龙套管内在长度决定是否加装金属杆，若死螺栓为断头螺栓，则加装金属杆件；否则，执行Step3；Step3：利用热熔焊技术对死螺栓进行加热处理，然后打磨熔池和焊渣，静置十几秒至数分钟不等；Step4：循环数次Step3。本发明利用热熔焊产生的高温加热死螺栓，使尼龙套管逐步软化，从而松动卡死大垫板内的死螺栓，进而实现死螺栓的拆卸，减少了轨道维修作业时间和工作强度，增加了轨道维修作业效率，降低了轨道维修作业成本。
