Description
Technical Field
The utility model belongs to the technical field of hang the contact net in the tunnel, concretely relates to anchor assembly fixed knot constructs under carrier cable.
Background
The overhead line system is an important component of an urban rail transit power supply system, is a special form power transmission line which is arranged along a rail transit line and supplies power to an electric locomotive, is a special power supply device for supplying power to the electric locomotive or an electric locomotive group for rail transit and has no standby power supply equipment. The contact net can always keep normal and stable contact current collection in the high-speed running of the locomotive, has enough wear resistance and good conductivity, has the service life as long as possible, strives for simple structure, and stable performance is easy to construct and maintain.
And a rigid-flexible transition system is arranged at the tunnel portal where the flexible suspension and the rigid suspension are connected. The pantograph suspension device is a key part for realizing seamless connection between the rigid suspension and the flexible suspension, and ensures stable transition of the pantograph between the two suspensions. The main components comprise a chemical anchor bolt, a wrist support device, a positioning device, a contact line, an overhead ground wire, a rigid-flexible transition element and the like.
At present, partial carrier cables are unbalanced in connection, so that the carrier cables are not required to be installed, and finally the resistance test is unqualified.
