Problems solved by technology
[0003] 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. When the mobile catenary is much higher than the height of the carriage, there is a safety hazard when the goods hoisted by the gantry crane pass through the mobile catenary
[0004] In some cases, the column of the mobile catenary is relatively close to the track, and the mobile catenary moves to the non-working position, which is relatively close to the train carriage. When loading and unloading goods, it is easy to touch the catenary cables and / or catenary wires on the mobile catenary

Embodiment Construction
[0057] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.
[0058] In the traditional existing technology, the contact wire is used to drive the movement of the wrist-arm support structure. The current mobile catenary is easy to form a bending point during the movement, because the length of the catenary is very long, and it is easier to form an arc. The wire rope itself has Due to the characteristics of thermal expansion and cold contraction, any wrist ...

The invention relates to a middle supporting column adjusting device for a mobile overhead line system, a mobile overhead line system and an operation method. One end of the connecting piece is directly or indirectly movably connected with a stand column; the other end of the connecting piece is directly or indirectly movably connected with a supporting structure; a moving mechanism is directly or indirectly arranged on the stand column and can move in the length direction of the stand column. One end of the supporting structure is directly or indirectly movably connected with the moving mechanism; a motor drives a chain to move to drive the moving mechanism to move in the length direction of the stand column and drive one end of the supporting structure to move, so that the other end of the supporting structure moves to a working position or a non-working position; the situation that bending points exist in the prior art can be effectively avoided, and the technical defect that an arc line appears in the prior art is overcome; the situations that in the prior art, pulling cannot be conducted, and a telescopic mechanism cannot be unfolded in place are avoided.
Description
technical field [0001] The invention belongs to the technical field of electrified railway mobile catenary, and in particular relates to a mobile catenary middle support adjusting device, a mobile catenary and an operation method. Background technique [0002] In the existing catenary, the gantry is installed at both ends, and the traveling device is arranged on the gantry, and the two ends of the moving contact line assembly are respectively connected. When the traveling device is walking, it can drive the contact line assembly to move and drive the entire contact line to move synchronously. . [0003] 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 carriag...
