洞内运输电瓶机车车轮拆装专用压床的设计及运用

Design and Application of Dedicated Press Machine for Wheel Dismounting of Transportation Battery Locomotive in Tunnel

城市地铁施工主要以盾构施工为主,而使用电瓶机车组水平运输是盾构施工耗材运输的主要渠道。在盾构机掘进过程中,电瓶机车编组通常满载渣土、以极高的频率往返于碴场与盾构机之间,导致车轮与轨道长时间的摩擦造成车轮磨损。由于施工现场维修条件简陋,维保人员只能依靠人工进行轮对拆卸、检修、组装等各项工作,造成电瓶机车的维保效率低,进而影响到盾构施工的正常进行。阐述了自主发明的一套隧道用电瓶机车车轮拆装专用压床,可用于快速拆装电瓶机车轮对,极大地提高了电瓶机车的维保效率。

The shield construction is the main method in urban subway construction,and the horizontal transportation of battery locomotive crew is the main method of shield construction consumables transportation.In the process of shield tunneling,the battery locomotive crew is usually loaded with muck,and it travels between the spoil yard and the shield machine at a very high frequency,resulting in long-term friction between the wheels and the track,and thus resulting in wheels wear.Due to the poor maintenance conditions at the construction site,the maintenance personnel can only rely on manual work for wheel set disassembly,maintenance,assembly and other work,resulting in the low maintenance efficiency of the battery locomotive,thus affecting the normal progress of shield construction.This paper introduces a set of dedicated press machine for dismounting the wheel of battery locomotive in tunnel,which can be used for quickly dismounting the wheel of battery locomotive and has greatly improved the maintenance efficiency of the battery locomotive.
