Horizontal rotation and flexible movement contact network control system and method thereof

Abstract

The invention relates to a horizontal rotation and flexible movement contact network control system and a method thereof. At a terminal, a mobile flexible contact network adopts an unilateral constant-tension compensation balance weight for carrying out tension compensation; at an initial end, a motor serves as a power mechanism to drive a power rotating cantilever to horizontally rotate so as to drive the mobile flexible contact network to be opened or closed; and at a middle end and a transition end, the horizontally rotated cantilever serves as a rotating assist so as to realize horizontal lateral displacement of the mobile flexible contact network. Automatic safety interlocking control of the whole processes is completed by virtue of a PLC (Programmable Logic Controller) as well as middle end and transition end radars, initial end and transition end video monitors, an initial end position sensor, a transition end grounding detection sensor, a load switch for fixing the flexible contact network and an initial end motor which are communicated with the PLC, thereby solving the problems that the cantilever structure suffers large lifting force, the flexible hanging mobile contact network has no tension compensation in the movement process, a following mechanism is uneven in stress and the synchronism is poor.

Description

technical field [0001] The invention relates to the technical field of electrified railway catenary, in particular to a horizontally rotating flexible mobile catenary control system and a method thereof. Background technique [0002] At present, electrified freight trains enter the cargo loading and unloading area and the maintenance garage are generally completed by diesel locomotive traction, and a small number of cargo loading and unloading areas or maintenance garages have realized the electrification design with catenary, and most of these catenaries are fixed and suspended, which restricts the way of cargo loading and unloading and vehicle overhaul work. [0003] In order to solve the above problems, rigid movable catenary systems and flexible movable catenary systems have been developed at home and abroad for different application situations in recent years. According to the length of the work area, it can be divided into point-type operation and line-type operation....

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a horizontally rotating flexible mobile catenary control system and its method, which can be used in large loading and unloading yards, container terminals, maintenance garages, etc. The control of the horizontally rotating flexible mobile catenary solves the problems of large lifting force on the wrist arm structure, no tension compensation during the movement of the flexible suspension mobile catenary, uneven force on the follower mechanism, and poor synchronization.
