The invention discloses a frame of an overhead line system maintenance operation vehicle without a middle beam. The frame comprises side frames, traction beams connected with the side beams and located at the two ends of the frame, sleeper beams connected with the side beams to form a main bearing structure, cross beams which are distributed at intervals and provided with two ends connected with the side beams, a power and auxiliary system installation base connected to the cross beams, a traction air cooling system air flue, a tunnel three-platform installation base, a hydraulic aerial cage hopper mounting seat, traction seats fixed to the side frames, hydraulic systems set on the traction beams, an air braking system and an electrical system accessory. The middle-beam-free overhead linesystem maintenance operation vehicle frame is longer, higher in bearing capacity and capable of meeting the requirement for installation of an operation mechanism, a traction power system and other components, and therefore the purpose of facilitating the maintenance operation of overhead line system suspension, a supporting device, a positioning device and the like is achieved.
本发明公开了一种无中梁接触网检修作业车车架,包括边梁、与所述边梁连接且位于车架两端的牵引梁、与所述边梁连接组成主承载结构的枕梁、多个间隔分布且两端分别与所述边梁连接的横梁、连接于所述横梁的动力及其辅助系统安装座和牵引风冷系统风道、隧道三平台安装座、高空作业车斗安装座、固定于所述边梁的牵引座、以及设于所述牵引梁的液压系统、空气制动系统和电气系统附件。本发明提供的无中梁接触网检修作业车车架,长度更长、承载能力更强,可满足作业机构、牵引动力系统等部件的安装,从而达到更加便于接触网悬挂、支持装置、定位装置等检修作业的目的。
