Problems solved by technology

[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. 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
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 approach

[0130] Another embodiment of the present invention: the support mechanism adopts a retractable support mechanism, and the retractable support mechanism stretches out to drive the bearing cable 1 and / or the contact line 2 to move from the non-working position to the working position; or The retractable support mechanism described above drives the catenary cable 1 and / or the contact line 2 to move from the working position to the non-working position. Such as Figure 6A to Figure 6C As shown, adopt described supporting mechanism to stretch out or withdraw in the mode of scissors row. Such as Figure 7A to Figure 7C As shown, stretching out is realized by adopting a telescopic step-by-step stretching method.

[0131] Such as Figure 7D As shown, a horizontal slideway 25 is set on the column, and a driving mechanism, such as an electric drive, is used to drive the support mechanism 4 to stretch out from the horizontal slideway to the working position; Horizontal slideway 25 so...

Abstract

The invention relates to a lifting type mobile contact network supporting device, a mobile contact network and an operation method. The lifting type mobile contact network supporting device comprises a stand column, a supporting mechanism and a moving mechanism and further comprises a carrier cable and / or a contact line. The supporting mechanism is directly or indirectly connected with the moving mechanism; the moving mechanism is directly or indirectly arranged on the stand column. The supporting mechanism is used for driving the carrier cable and / or the contact line to move to a working position or a non-working position or to be switched between the working position and the non-working position. The moving mechanism moves to drive the supporting mechanism to ascend or descend, and therefore the height of the carrier cable and / or the contact line is driven to ascend or descend. When the gantry crane hoists goods, especially when the movable contact net moves to a non-working position and is close to a train carriage, the goods or loading and unloading tools can be effectively prevented from colliding with the carrier cable and / or the 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...
