The invention discloses a catenary constant tension pay-off car, comprising a pay-off device fixedly arranged on a road flat car and penetrated through bearing wires in sequence, a guiding device, a tension applying device, a wire column and a control device. A slide rail device and a hydraulic cylinder for moving a bracket along the slide rail device are fixedly arranged on the road flat car. A hydraulic motor is fixedly arranged on the bracket, and the direction of force applying when the hydraulic motor provides tension for a winding device is opposite to the direction of paying-off of thewinding device. The control device comprises a generator set and a hydraulic control assembly; the hydraulic control assembly comprises a signal control assembly and an oil storage device, a hydraulicoil pump and an integrated valve group connected in sequence. The pay-off car has a high degree of automation, the modularization is achieved, the size is small, constant tension is ensured, and thetension is automatically adjusted according to actual conditions during the working process. In addition, the quality of winding is ensured, the service life is long, the disassembly and assembly areconvenient, the orientation is stable, the energy is saved, the emission is reduced, the environmental pollution is low, and the pay-off car is suitable for all catenary pay-off cars.

    本发明公开了一种接触网恒张力放线车,包括固设于路用平车上且承导线依次穿过的放线装置、导向装置、张力施加装置、导线柱和控制装置,路用平车上固设有滑轨装置和用于使支架沿着滑轨装置运动的液压油缸,支架上固设有液压马达,液压马达为绕线装置提供张力时的施力方向与绕线装置的放线方向相反;控制装置包括发电机组和液压控制组件;液压控制组件包括信号控制组件和依次连接的储油装置、液压油泵和集成阀组。本发明的自动化程度高,模块化、尺寸小,可保证张力恒定、并在工作过程中根据实际情况自动调节张力,保证放线质量,使用寿命长,拆装方便,导向稳定,节能减排,对环境污染较小,适用于所有接触网放线车。
