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

specific Embodiment 1

[0099] see figure 1 and figure 2 As shown, in this embodiment, the distance between the top of the variable-height support mechanism and the rail surface is variable, and the setting mechanism adopted is: the variable-height support mechanism includes a telescopic support mechanism, and the telescopic support mechanism The elongation of the mechanism drives the support mechanism to rise, and the retraction of the telescopic support mechanism drives the support mechanism to descend. The upper lifting unit 7 is accommodated in the lower lifting unit 6 in this embodiment. figure 1 The supporting mechanism is in the working position (on the top of the railway, the pantograph of the freight train 5 can take power from the contact wire 4), and the supporting mechanism adopts the rotating mode to move the catenary cable 3 and or the contact wire 4 to the non- Working position (one side of railway), support mechanism can adopt the mode of horizontal rotation, has and can adopt tele...

specific Embodiment 2

[0110] In this embodiment, the distance between the top of the variable-height support mechanism and the rail surface is variable, and the setting mechanism adopted is: the variable-height support mechanism includes a multi-level lifting mechanism, and the multi-level lifting mechanism rises Or fall, and drive the directly or indirectly set support institutions to rise or fall.

[0111] It should be added that the setting method of the multi-level lifting mechanism in this embodiment is as follows:

[0112] The lower end of the multi-stage lifting mechanism is arranged below the ground or in the artificial building foundation pit;

[0113] At least one level of the multi-level lifting mechanism is set below the ground or in the artificial building foundation pit; or

[0114] Part of the main body of at least the lowest level in the multi-level lifting mechanism is arranged below the ground or in the artificial building foundation pit.

[0115] In this embodiment, after the m...

specific Embodiment 3

[0118] Such as Figure 7 As shown, in this embodiment, the distance between the top of the variable-height support mechanism and the rail surface is variable, and the setting mechanism adopted is: the variable-height support mechanism is movably connected with the base 9, and on the base 9 A connecting piece 10 is provided, through which the height-variable support mechanism is movably connected with the base 9 . The height-variable support mechanism has a vertical state and a tilted state.

[0119] Include push-pull mechanism 11 in the present embodiment, as Figure 7 As shown, the push-pull mechanism is used to push the height-variable support mechanism to be in a vertical state, or as Figure 8 As shown, the pushing mechanism is also used to pull the height-variable support mechanism to fall down and be in a dumped state. The pushing mechanism adopts an electric pushing mechanism or a hydraulic pushing mechanism. The push mechanism at least adopts an electric push mecha...

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...
