Abstract

The invention relates to a lifting type mobile catenary supporting device, a mobile catenary and an operation method, the lifting type mobile catenary supporting device comprises height-variable supporting mechanisms and supporting mechanisms, and the supporting mechanisms are directly or indirectly arranged on the height-variable supporting mechanisms; and the distances between the tops of the height-variable supporting mechanisms and the rail surface are variable. A plurality of height-variable supporting mechanisms in the mobile catenary increase the distance between the tops of the height-variable supporting mechanisms and the rail surface, and the heights of carrier cables and / or contact lines in the supporting mechanisms are increased; the distance between the tops of the height-variable supporting mechanisms and the rail surface is shortened, and the heights of carrier cables and / or contact lines in the supporting mechanisms are lowered. The whole supporting mechanism can descend to be not higher than the height of the highest position of a freight train, so that when the gantry crane hoists goods, especially when the mobile catenary moves to be close to a train carriage, the goods or loading and unloading tools can be effectively prevented from colliding with a carrier cable and / or a contact line, and safety guarantee is provided for goods loading and unloading.

Description

technical field

[0001] The invention belongs to the technical field of mobile catenary, and in particular relates to a lifting type mobile catenary supporting device, a mobile catenary and an operation method. Background technique

[0002] The catenary wire and catenary cables in the existing catenary cannot be completely moved to the side of the railway. During hoisting operations, they need to be moved from the freight yard to the mobile train. The gantry crane needs to pass above the mobile catenary to be hoisted onto the train. At this time, the mobile catenary is much higher than the height of the carriage, and there are potential safety hazards when the goods hoisted by the gantry crane pass through the mobile catenary. In some cases, the column of the mobile catenary is relatively close to the track, and the mobile catenary moves to a non-working position, which is relatively close to the train carriage. When loading and unloading goods, it is easy to touch the catena...
