Abstract

The invention discloses a novel indoor and outdoor contact line connection and isolation device. The device comprises an outdoor dead anchor fixed contact net segment and an indoor dead anchor moving contact net segment in a wall, and the outdoor dead anchor fixed contact net segment comprises a pull line, a single-arm suspension bracket, an insulator, a contact line transition frame and a busbar; the indoor dead anchor moving contact net segment comprises a pull line, a pre-arranged installation steel frame, a movable beam, an insulator, a movable trolley, a contact line transition frame and a busbar, the pre-arranged installation steel frame is fixed to the inner wall of the wall and is provided with the movable beam, the movable beam is provided with the insulator, the tail end of the insulator is connected to the busbar, the contact line transition line is fixedly connected with the busbar, a movable trolley is arranged on the movable beam and is connected with the movable beam in a sliding mode, and a speed reduction motor driving the movable trolley is arranged on the pre-arranged movable beam. The mode that the movable trolley and the movable beam are connected in a sliding mode is adopted for the device, the structure is simple, and assembling is easy; maintenance is not needed after the device is put into use, and movement is stable.

Description

technical field [0001] The invention relates to the field of railway locomotive power supply line engineering equipment, in particular to a new type of equipment for connecting and isolating indoor and outdoor contact lines. Background technique [0002] At present, there must be a catenary to provide power to the electric locomotive above the electrified railway line. Due to the live catenary line above the railway, in cold climate areas, areas prone to blowing sand weather and areas with harsh natural conditions, indoor loading and unloading operations and maintenance operations Waiting has certain difficulties, and it is not safe. There are two solutions at the present stage. One is that after the train pulled by the electric locomotive enters the station track with catenary, the internal combustion shunting machine will be used to pull the whole train, and the train that needs to be loaded, unloaded or overhauled will be pulled to stop Work in a warehouse without cate...
