The invention provides an electric heat tracing guide cylinder of a passenger train, and belongs to the technical field of railway vehicles. The guide cylinder comprises an inner cylinder, an outer cylinder and a hoop, and a heat tracing band is wound on the outer side surface of the inner cylinder; the outer cylinder fixedly sleeves the outer side of the inner cylinder, and a gap is formed between the outer cylinder and the inner cylinder; the outer cylinder is of a split structure; and the hoop sleeves the outer surface of the outer cylinder. According to the electric heat tracing guide cylinder of the passenger train, the outer cylinder of the split type structure is used for sleeving the outer side of the inner cylinder, the outer cylinder is fixed, then the split type structure is fastened through the hoop, and the stability of the whole electric heat tracing guide cylinder is guaranteed. When overhauling is needed, the hoop can be detached firstly, then the split type structure is directly disassembled, the heat tracing band in the gap can be replaced, after maintenance work is finished, the split type structure is arranged outside the inner cylinder in a sleeving mode again, installation can be recovered, and the electric heat tracing guide cylinder can be normally used. By means of the mode, maintenance operation steps are simplified, maintenance time is saved, the maintenance period is shortened, and maintenance efficiency is improved.
本发明提供了一种铁路客车电伴热导筒,属于轨道车辆技术领域,包括内筒、外筒以及卡箍,内筒的外侧面缠绕伴热带;外筒固定套设于内筒的外侧,且与内筒之间设有间隙;外筒为分体式结构;卡箍套设于外筒的外侧面上,用于紧固外筒,本发明提供的铁路客车电伴热导筒,使用分体式结构的外筒套在内筒外侧,并与外筒固定,然后使用卡箍将分体式结构紧固,保证整个电伴热导筒的稳定性,在需要检修时,可以先拆除卡箍,然后将分体式结构直接拆开,即可更换间隙内的伴热带,检修工作结束后,将分体式结构重新套设于内筒外就可以恢复安装,使电伴热导筒正常使用,采用这种方式,简化了维修操作步骤,节约维修时间并缩短检修周期,提高了检修效率。
