MODULAR CONSTANT TENSION PAY-OFF VEHICLE

摘要

A modular constant tension pay-off vehicle, comprising winding devices (5), a guide device (9), a tension applying device (12), a line post (20), and a control device which are fixedly provided on a rail flat car (13) and through which an overhead contact line (10) passes in sequence. Slide rail devices (8) and hydraulic oil cylinders (14) used for enabling supports (1) to move along the slide rail devices (8) are fixedly provided on the rail flat car (13). Hydraulic motors (17) are fixedly provided on the supports (1). When the hydraulic motors (17) provide tension for the winding devices (5), the direction of force application is opposite to the pay-off direction of the winding devices (5). The control device comprises a generating set (25) and a hydraulic control assembly. The hydraulic control assembly comprises a signal control assembly, and an oil storage device (22), a hydraulic oil pump, and an integrated valve group (26) connected in sequence.
